In order to solve the technical problem that the concrete base plates of the long and large bridge are required to be connected and formed at one time, the construction of the concrete base plates on the long and large bridge adopts a construction method of arranging a plurality of temporary end thorns and a conventional area, the concrete base plates are poured in blocks, and the post-pouring belt of the base plates is reserved, so that the post-pouring belt reserved in the construction of the concrete base plates on the bridge can prevent the concrete from shrinking and cracking and release most of the shrinkage stress of the concrete.

When the track structure is routinely overhauled according to the work section of the railway bureau, the base plate post-cast strip is broken and cracked, which is a common defect of the ballastless track structure on the bridge, and the existing post-cast strip repairing method comprises a uncovering plate complete repairing method and a base plate cross-linking side width reinforcing repairing method. Although the post-cast strip fracture joint can be thoroughly repaired by adopting a plate uncovering thorough repair method and the post-cast strip fracture joint is restored to the original construction state, the repair method has the advantages of complex working procedures, great influence on travelling crane and long repair construction time, 9 skylight periods are needed for completing single-line repair construction, 18 skylight periods are needed for completing double-line construction, and the time consumption is long; the base plate transverse connection side width reinforcing repair method is relatively simple, has small damage to the main structure of the existing track and small interference to the travelling crane, and has the defects that the large-area whole concrete poured can generate shrinkage cracks, the surface of new and old concrete is contacted with the new and old concrete and cracks are generated, the repair time of the base plate post-cast strip is short compared with that of the plate uncovering complete repair, but 10 skylight periods are required for completing all double-line construction.

Chinese patent with application number CN201910759609.X discloses a device, a system and a method for breaking a post-cast strip of a ballastless track base plate. This patent need not accomplish the abolishment to the post-cast strip under the condition of taking off the board promptly, and can furthest's remain the structure of steel reinforcement cage when the construction, realizes rejecting concrete structure under the harmless state of reinforcing bar, makes the abolishing speed in post-cast strip improve 20 ~ 50 times.

However, the high-pressure nozzle of the breaking device can move back and forth and up and down, but cannot move left and right. In actual operation, the gun rod is only punched and broken through gaps among the reinforcement cages, at least two holes are blocked by the shear nails, the gun rod cannot penetrate through the gaps, in the single-hole breaking process, the temporary space for stripping concrete is lacked, the high-pressure water ejected by the spray head is obstructed by the large amount of high-pressure water filled in the closed space, and the broken stone slag is difficult to remove, so that the deeper the breaking depth is, the lower the efficiency is, and the device cannot complete the concrete breaking of the post-cast strip in effective time.

In the process of breaking the post-cast strip by the high-pressure water, along with the breaking of the high-pressure water, the distance between the high-pressure spray nozzle 56 at the front end of the rotary breaking mechanism 5 and the post-cast strip is increased, the advancing distance of the high-pressure water is gradually increased, and the breaking force of the high-pressure water on the post-cast strip is gradually reduced, so that the high-pressure spray nozzle 56 is required to be gradually advanced in the process of breaking the post-cast strip by the high-pressure water, the distance between the high-pressure spray nozzle 56 and the post-cast strip is always kept unchanged, the breaking force exerted by the high-pressure water on the post-cast strip is always kept unchanged, the breaking effect of the high-pressure water on the post-cast strip is always kept consistent, and the post-cast strip can be quickly broken. In the implementation, the front and back movement of the high-pressure spray head 56 is realized through the first linear module 21, so that the distance between the high-pressure spray head 56 and the post-cast strip is always kept unchanged, and the post-cast strip is quickly broken.

As an optimized solution of the present embodiment, as shown in fig. 1, the left-right moving mechanism 3 includes a second linear module 31 mounted on the module assembling plate 23, the second linear module 31 is perpendicular to the first linear module 21, and the output slider thereof moves in the left-right direction. Because upper concrete does not have the reinforcing bar, but the lateral shifting of mechanism promotes and abolishes efficiency. In the implementation, the high-pressure spray head 56 moves left and right through the second linear module 31, so that the post-cast strip is quickly broken.

As a preferable solution of the present embodiment, as shown in fig. 3 and 4, the lifting mechanism 4 includes a screw fixing plate 41, a connecting plate 42, a rotation assembly plate 43, a screw 44, a handle 45, and a polish rod 46;

the screw rod fixing plate 41, the connecting plate 42 and the rotating assembly plate 43 are sequentially arranged from top to bottom; the upper end of the screw rod fixing plate 41 is arranged on an output slide block of the second linear module 31, and the bottom end of the screw rod fixing plate is fixedly connected with the connecting plate 42 through a bearing seat 47; a nut is arranged on the rotary assembling plate 43, the screw rod 44 penetrates through the nut and is in threaded connection with the nut, the top end of the screw rod 44 penetrates through the connecting plate 42 and then is arranged on a bearing in the bearing seat 47, and the bottom end of the screw rod is connected with the handle 45; four polished rods 46 are arranged and are fixedly arranged on the screw rod fixing plate 41 and downwards penetrate through the connecting plate 42 and the rotating assembly plate 43 in sequence.

The lifting mechanism 4 is used for adjusting the height of the high-pressure spray head 56, and the lifting mechanism 4 is used for changing the height of the high-pressure spray head 56, so that the horizontal height of high-pressure water is changed, and the high-pressure water can break the post-cast strip with the corresponding height. Specifically, the screw rod 44 is rotated by rotating the handle 45, the screw rod 44 is rotated on the bearing in the bearing seat 47, the rotating assembly plate 43 on the screw rod 44 is driven to move up and down, and then the rotating breaking mechanism 5 mounted on the rotating assembly plate 43 is driven to move up and down, so that the high-pressure spray head 56 on the rotating breaking mechanism 5 is lifted up and down. By providing four polish rods 46, the rotation assembling plate 43 slides thereon, and the rotation assembling plate 43 is restrained to move smoothly in the vertical direction.

As an optimized solution of the present embodiment, as shown in fig. 3 and 4, the rotary breaking mechanism 5 includes a rotary motor 51, a hollow rotating shaft 52, a rotary joint 53, a gun rod 54, a gun rod holder 55, and a high-pressure nozzle 56;

the rotating motor 51 is connected with a hollow rotating shaft 52 through a belt set, one end of the hollow rotating shaft 52 is connected with a rotating joint 53, and the other end of the hollow rotating shaft is connected with a gun rod 54; the gun bar holder 55 is installed at the bottom end of the elevating mechanism 4, the gun bar 54 passes through the gun bar holder 55, and the high pressure nozzle 56 is installed at the front end thereof.

The rotary breaking mechanism 5 is used for rotatably spraying high-pressure water to break the post-cast strip. Specifically, the rotary joint 53 is connected with a high-pressure water pipe, and high-pressure water enters the hollow rotating shaft 52 from the rotary joint 53, then enters the gun rod 54, and finally is sprayed out from the high-pressure spray head 56. When the high-pressure spray head 56 sprays high-pressure water, the rotating motor 51 drives the hollow rotating shaft 52 to rotate through the belt set, the hollow rotating shaft 52 drives the gun rod 54 to rotate, and then the high-pressure spray head 56 at the front end is driven to rotate, so that high-pressure water columns sprayed by the high-pressure spray head 56 rotate, the post-cast strip is broken through the high-pressure rotating water, and the breaking effect of the post-cast strip is improved.

Compared with the prior art, this embodiment has changed the transmission mode between rotating electrical machines 51 and the hollow rotating shaft 52, changes prior art's chain drive or gear drive into the belt group transmission of this embodiment, because a large amount of ballast that produces in the actual work progress has certain probability card rifle, leads to the rifle bar to rotate inefficacy, and chain and gear revolve are rigid connection, and the torsion that produces behind the card rifle can produce fatigue impact to spare part, can lead to wearing and tearing, fracture etc. for a long time. The belt transmission is flexible connection, and the torque impact is offset through the toughness of belt itself, can provide effectual protection to spare part.

Preferably, as shown in fig. 6 to 9, the high pressure nozzle 56 includes a water inlet part 01 at a rear end and a water spray part 02 at a front end, wherein a water inlet 011 is provided in the water inlet part 01, a plurality of first water spray holes 021 are provided in a front end surface of the water spray part 02, a plurality of second water spray holes 022 inclined upward and third water spray holes 023 inclined rearward are provided in an outer sidewall, and the first water spray holes 021, the second water spray holes 022 and the third water spray holes 023 are all communicated with the water inlet 011.

In this embodiment, the inner diameter of the water inlet 011 is larger than the inner diameter of the water spray holes, the water inlet 011 is connected to a water supply mechanism for high pressure water, and the high pressure water enters the nozzle through the water inlet 011 and is sprayed out from the first water spray hole 021, the second water spray hole 022 and the third water spray hole 023 of the nozzle to crush the concrete. All be provided with a plurality of hole for water sprayings on the preceding terminal surface and the lateral wall at water spray portion 02, can break the concrete from different angles, increase the probability of looking for concrete gap or weak point, make to break the effect better, break more thoroughly.

The third hole 023 is set in this embodiment, and is considered based on the following three points:

1. the high-pressure water jet breaks concrete mainly by means of water jet to find gaps or weak points of the concrete, the forward first water jet hole has certain residues after the gun rod moves forward, if the gun rod is struck by the water jet backwards, the residual concrete can be broken from different angles, the probability of finding the gaps or the weak points of the concrete is increased, the breaking effect is better, and the concrete is broken more thoroughly.

2. A large amount of concrete residues are remained in the holes in the breaking process, particularly after deep breaking, the residues are accumulated too much and are not beneficial to the movement of a follow-up gun rod, and backward spray holes can flush out the broken slag to achieve the effect of actively discharging the slag.

3. When the gun rod penetrates into the inside of the breaking hole, particularly after a closed space is formed, concrete lacks a free surface and cannot be stripped efficiently, the concrete is broken by the striking force of high-pressure water jet, and a large amount of water with certain pressure is extremely easy to accumulate in the closed space in the state. The water is filled in the space to form certain resistance to the high-pressure water sprayed by the spray head, the hitting power of the high-pressure water is greatly reduced, meanwhile, besides water is accumulated in the space, a large amount of concrete grains are also accumulated in the space, the grains cannot flow out of the space along with the vortex effect, and the hitting power is greatly weakened after the grains block the water jet, so that the breaking efficiency is linearly reduced. And the backward high-pressure water jet forms a vacuum negative pressure belt in the opposite direction of the jet. The negative pressure can suck out the accumulated water and the stone slag, and the accumulated water and the stone slag are far away from the nozzle area, so that the breaking efficiency is improved.

The preceding terminal surface of hydrojet portion 02 is provided with two first hole for water 021, and two first hole for water 021 are the Y type with inlet opening 011 to right the place ahead concrete is abolished, increases certain abolishing scope simultaneously, for the barral of a gun advances and provides effectual space, offsets horizontal recoil each other simultaneously, does not eccentrically when keeping the barral of a gun to rotate. The included angle between the central axis of the first water spray hole 021 and the central axis of the water inlet hole 011 is 155-170 degrees. Because the contained angle is bigger, abolish the dynamics and be big more, speed is faster, but the aperture is less, is unfavorable for row's sediment. Experiments prove that the effect is best when the included angle is 165 degrees.

The symmetry is provided with two ascending second hole for water sprayings 022 of slope on the lateral wall of hydrojet portion 02 to the offside concrete is broken away, increases and breaks the scope, provides certain row's sediment impact effect simultaneously, and keeps the barral of a gun rotation not off-centre. The included angle between the central axis of the second water spray hole 022 and the central axis of the water inlet hole 011 is 80-89 degrees. The larger the angle, the better the breaking effect, but the larger the energy loss, and the certain slag removing effect must be considered at the same time. Experiments prove that the effect is best when the included angle is 85 degrees.

Two third water jet holes 023 which are inclined backwards are symmetrically arranged on the outer side wall of the water jet part 02, and the third water jet holes 023 are positioned behind the second water jet holes 022. On one hand, the nozzle is struck by water jet backwards, so that the residual concrete can be broken from different angles, and the probability of searching for concrete gaps or weak points is increased; on the other hand, the backward water spray holes can flush out the slag, so as to achieve the effect of actively discharging slag; in addition, the high-pressure water jet ejected backwards forms a vacuum negative pressure belt in the opposite direction of the jet, the vacuum negative pressure belt can suck out accumulated water and stone slag and keep away from the nozzle area, and the breaking efficiency is improved. The angle between the central axis of the third water spray hole 023 and the central axis of the water inlet hole 011 is 40-50 degrees. Since the smaller the angle, the better the slag flushing effect toward the rear side, but the greater the water energy loss. Experiments prove that the effect is best when the included angle is 45 degrees.

The plane formed by the central axes of the two first water spray holes 021 and the plane formed by the central axes of the two second water spray holes 022 are perpendicular to each other and coplanar with the plane formed by the central axes of the two third water spray holes 023, so that the mechanical processing is facilitated, the porous layout is carried out in the minimum space, and meanwhile, the recoil of the water jet can be effectively balanced.

The spray head is in a stepped cylindrical shape, and is arranged in a cylindrical shape, so that the friction resistance generated by the rotation of the spray head in the operation process is reduced; the external diameter of the water inlet part 01 is smaller than that of the water spray part 02, so that when the water inlet part 01 is installed, the water spray part 02 on the ladder limits the installation of the water inlet part 01. Straight surfaces 024 are symmetrically arranged on the outer side wall of the rear end of the water injection part 02, so that the straight surfaces 024 can be clamped by using a mounting tool, and the spray head is rotated to be mounted or dismounted.

The outer wall of the water inlet part 01 is provided with external threads so as to be detachably arranged on the water supply mechanism; first hole for water spraying 021, second hole for water spraying 022 and third hole for water spraying 023 exit end inner wall all are provided with the internal thread, can install detachable jam screw on the internal thread, and the hole for water spraying that need not use is sealed according to actual demand, remains the hole for water spraying that needs to use. In this embodiment, the two first water holes 021, the two second water holes 022, and the two third water holes 023 are in a rice shape with the water inlet 011.

The locking mechanism 6 is used for laterally locking the frame 1. When the support frame is used, the tightly-pushing cylinder 61 is tightly abutted to the ballastless tracks on the two sides, so that the frame 1 is fixedly installed between the two ballastless tracks, the frame 1 is fixed, and the frame 1 is more stably installed. This embodiment adopts tight cylinder 61 in top to carry out side direction locking because there is certain error because ballastless track double-line bed plate interval on-the-spot actual dimension and design drawing, and the design size of frame must be less than this size, therefore when the line-to-line was placed to the frame, can follow perpendicular track direction round trip movement, adopts tight cylinder 61 in top to lock fast, avoids the frame to remove. In the work progress, the high pressure water jet can produce great recoil, and this recoil becomes the loading of irregular tired formula, and the tight mode in cylinder top compares in other tight modes in top (for example screw rod top tightly), can effectively prevent because the irregular change of the tight power in top leads to the pine to take off.

As an optimized solution of the present embodiment, as shown in fig. 1 and 2, the breaking device further includes a vertical slide rail mechanism 7 mounted on the front end door type frame 11, and the vertical slide rail mechanism 7 includes a second guide rail 71, a second slider 72, a slider connecting frame 73, and a connecting rod 74;
