Referring to figure 1, prior to piling on water, it is necessary to erect a pontoon 11 carrying a pile driver for use as a water platform 1. The above-water platform 1 is formed by connecting a plurality of buoyancy tanks 11, one or more buoyancy tanks 11 are selected from the buoyancy tanks 11 to install positioning piles 2, the positioning piles 2 are usually steel pipes, and the positioning piles 2 are inserted into a river bed to fix the buoyancy tanks 11, so that the invention provides a positioning mechanism 12 to realize the positioning of the buoyancy tanks 11.

In this embodiment, the positioning mechanism 12 is installed by selecting the buoyancy tanks 11 at the four corners of the water platform 1. Fig. 2 is a top view of the buoyancy tank with the positioning mechanism installed, and fig. 3 is a front view of the buoyancy tank of fig. 2. The positioning mechanism 12 provided in this embodiment includes a fixed seat 14 for inserting the positioning pile 2 and a movable seat 13 disposed opposite to the fixed seat 14, and the movable seat 13 and the fixed seat 14 are disposed separately. Wherein, the fixing seat 14 is fixedly connected to a buoyancy tank 11 of the above-water platform 1, the buoyancy tank 11 is hollow, and the buoyancy tank 11 is provided with a gap for people to enter.

In this embodiment, as shown in fig. 4 and 5, the bottom of the fixing seat 14 is fixedly connected to the bottom surface inside the floating box 11, wherein the fixing seat 14 is a hollow circular tube, and correspondingly, a hole for the positioning pile 2 to pass through is formed in the bottom surface inside the floating box 11, and the aperture of the hole is smaller than the inner aperture of the fixing seat 14. The spud 2 is put into the fixing seat 14 from the upper part of the floating box 11 and inserted into the floating box 11, and falls into the river bed by the gravity of the spud 2. Since the spud 2 for pile driving is a heavy object, if the spud 2 directly touches the floating box 11 when the fixing base 14 is inserted, the surface of the floating box 11 is easily damaged, so in this embodiment, the top of the fixing base 14 penetrates the top surface of the floating box 11 and exposes the top surface of the floating box 11, and the distance L1 between the top of the fixing base 14 and the top surface of the floating box 11 can be set to be 200mm-500mm (as shown in fig. 5), and this distance plays a guiding role for inserting the spud 2 into the floating box 11.

Further, in order to strengthen the connection between the bottom of the fixing seat 14 and the buoyancy tank 11, a plurality of reinforcing ribs 15 are arranged on the bottom surface inside the buoyancy tank 11, as shown in fig. 5, and are uniformly arranged on the circumferential side wall of the bottom of the fixing seat 14, and meanwhile, in order to strengthen the strength of the side wall of the fixing seat 14 exposed out of the top surface of the buoyancy tank 11, a plurality of first annular plates 144 are also arranged in the axial direction of the outer wall of the fixing seat 14 exposed out of the top surface of the buoyancy tank 11, as shown in fig. 4.

When the spud 2 is inserted into the fixing seat 14, the surface of the spud 2 is directly contacted and rubbed with the inner side wall of the fixing seat 14, a plurality of first cylinders 141 in a substantially strip shape are uniformly distributed on the inner side wall of the fixing seat 14, each first cylinder 141 has the same curvature radius, wherein the length of the first cylinder 141 is substantially two thirds of the height of the fixing seat 14. As shown in fig. 4 and 5, when the spud 2 is inserted into the fixing base 14, the spud 2 makes tangential line contact with each first cylinder 141, thereby protecting the side wall of the fixing base 14 to the maximum extent. In addition, when the positioning pile 2 is inserted into the fixing seat 14 or pulled out from the fixing seat 14, the positioning pile 2 and the fixing seat 14 are not parallel in most cases, and in order to avoid the end of the first cylinder 141 obstructing the positioning pile 2, the axial end face of the first cylinder 141 is arranged in an inclined plane shape, wherein the axial end face of the top of the first cylinder 141 is inclined downwards, and the axial end face of the bottom of the first cylinder 141 is inclined upwards, in this embodiment, the angle α between the axial end face of the first cylinder 141 and the side wall of the fixing seat 14 is 20 ° to 45 °. Thus, when the positioning stud 2 is initially placed in the fixing seat 14, the positioning stud falls into the fixing seat 14 according to the inclined orientation of the axial end surface of the first cylinder 141, and the coaxial arrangement between the first cylinder 141 and the fixing seat 14 is ensured at this time.

Further, a first through hole 143 for inserting the first lock pin is formed in the fixing base 14 exposed out of the top surface of the buoyancy tank 11, and accordingly, a plurality of positioning holes 21 are axially formed in the positioning pile 2, and the plurality of positioning holes 21 are linearly arranged along the outer wall of the positioning pile 2, as shown in fig. 6. After the spud 2 is inserted into the fixing base 14, the technician may insert the first locking pin into the positioning hole 21 through the first through hole 143 to position the spud 2. In addition, after the first lock pin is inserted into the positioning pile 2, the first through hole 143 bears the acting force on part of the positioning pile 2, so that the first lock pin is arranged between the two annular plates, and the first annular plate 144 strengthens the side wall strength of the periphery of the first through hole 143 and avoids deformation.

In this embodiment, the positioning mechanism 12 further includes a telescopic member, the telescopic member can select a hydraulic cylinder, one end of the telescopic member is fixedly connected to the floating box 11 where the fixed seat 14 is located, and the other end of the telescopic member is connected to the movable seat 13. Specifically, as shown in fig. 4 and fig. 6, two expansion pieces may be symmetrically disposed in the circumferential direction of the fixed seat 14, one end of each expansion piece is fixed on the bottom surface inside the buoyancy tank 11, the other end of each expansion piece penetrates through the top surface of the buoyancy tank 11 and is connected to the movable seat 13, for example, the cylinder body of the hydraulic cylinder is fixedly connected to the bottom surface inside the buoyancy tank 11, and the telescopic rod of the hydraulic cylinder penetrates through the top surface of the buoyancy tank 11 and is connected to the movable seat 13, so that the movable seat 13 has a large stroke. Of course, the telescopic members may be directly mounted on the top surface of the buoyancy tank 11. Furthermore, the installation seats 16 are symmetrically arranged on the bottom surface of the inner part of the floating box 11 relative to the fixed seat 14, and the telescopic pieces are fixedly connected to the installation seats 16. Specifically, the mounting seat 16 is formed by two wing plates, and the two wing plates can clamp the telescopic piece through fasteners such as bolts and screws.

Further, the movable seat 13 is similar to the fixed seat 14, and is generally a hollow circular tube, and a plurality of second annular plates 134 are also axially disposed on the outer wall of the movable seat 13, as shown in fig. 4, so as to enhance the strength of the side wall of the movable seat 13. Meanwhile, the movable seat 13 is provided with a second through hole 133 for inserting the second lock pin, and the second through hole 133 is arranged between the two second annular plates 134 for enhancing the strength of the side wall of the peripheral fixed seat 14 of the second through hole 133. A mounting plate 132 may be further provided outside the movable base 13, and the other end of the telescopic member is connected to the mounting plate 132 after passing through the top surface of the pontoon 11.

In the present invention, the two ends of the movable seat 13 can be pulled to reciprocate up and down by using the hydraulic cylinders, in this embodiment, since the buoyancy tanks 11 at four corners are selected to install the positioning mechanism 12 on the whole water platform 1, and 4 positioning piles 2 are used for positioning, wherein each positioning pile 2 is pulled by using two hydraulic cylinders through the movable seat 13, and the jacking force of each hydraulic cylinder can reach 30 tons.

In addition, when the spud 2 is inserted into the movable seat 13, in order to ensure that the wall surface of the movable seat 13 does not directly contact and rub with the surface of the spud 2, a second cylindrical body 131 having a bar shape corresponding to the first cylindrical body 141 is disposed on the inner side wall of the movable seat 13, and the second cylindrical body 131 and the first cylindrical body 141 have the same curvature radius. As shown in fig. 5, when the spud 2 is inserted into the movable seat 13, the spud 2 is tangent to each second cylinder 131, so as to protect the side wall of the movable seat 13 to the maximum extent. Meanwhile, the included angle alpha between the axial end surface of the second cylinder 131 and the side wall of the movable seat 13 is 20-45 degrees. Thus, when the positioning pile 2 is initially placed in the movable seat 13, it falls into the movable seat 13 according to the inclination of the axial end face of the second cylinder 131, and the coaxial arrangement between the cylinder and the movable seat 13 is ensured at this time.

In addition, according to the installation manner of the telescopic member on the buoyancy tank 11 (one end is fixedly connected to the inner bottom surface of the buoyancy tank 11, and the other end passes through the top surface of the buoyancy tank 11), two parts in contact with the telescopic member exist on the buoyancy tank 11, namely the inner bottom surface of the buoyancy tank 11 in contact with the telescopic member and the top surface of the buoyancy tank 11 in contact with the telescopic member, when the telescopic member is in action, the contact part of the buoyancy tank 11 can bear the acting force thereof, the acting force in action is larger, and in order to prevent the contact part of the buoyancy tank 11 from deforming, in the embodiment, the wall thickness L2 of the contact part of the telescopic member on the buoyancy tank 11 is larger than the wall thickness L3 of the other part of the plate where the contact part is located, wherein the wall thickness L2 is approximately more than 10mm compared with the wall thickness L3, and. Meanwhile, the contact part of the fixed seat 14 and the buoyancy tank 11 is locally reinforced, so that the fixed seat 14 and the contact part of the telescopic piece and the buoyancy tank 11 form a locally reinforced area.

The working process is as follows:

according to fig. 6, the spud 2 is positioned: inside spud 2 inserted buoyancy tank 11 from sliding seat 13, fixing base 14, relied on spud 2 gravity to fall into the riverbed, after spud 2 can't fall according to the gravity, technical staff inserted the locating hole 21 that corresponds with it earlier through the first through-hole 143 of fixing base 14 with the first lockpin, comes the spud 2 of location. And starting the hydraulic cylinder, lifting the movable seat 13, selecting the lifting height according to the required pressing distance, inserting the second lock pin into the positioning hole 21 corresponding to the second lock pin through the second through hole 133 of the movable seat 13, pulling out the second lock pin, and pressing down the positioning column through the movable seat 13 by the hydraulic cylinder to finish the pressing down of the positioning pile 2 at one time. Can carry out many times spud 2 according to the riverbed condition and push down, need not to push down the back again as spud 2, first lockpin passes through first through-hole 143 and inserts in corresponding locating hole 21, locks spud 2, accomplishes spud 2 and fixes a position.
