Technical Field

The invention relates to the field of railway maintenance equipment, in particular to a rail tool car for overhauling.

Background

Railway maintenance mainly comprises two aspects of railway line maintenance and railway building maintenance. Maintenance of railway lines is the maintenance and repair work performed on roadbeds, tracks, and the like; railway building maintenance is the maintenance and repair work performed on railroad bridges, tunnels, house buildings, and the like. The main tasks of railway maintenance are as follows: prevent the equipment from abnormal permanent deformation and various diseases, delay the aging of each part of the equipment, prevent abnormal abrasion and prolong the service life; the overlimit permanent deformation and various diseases are eliminated, so that the equipment is always kept in a good state; local or total periodic repair reinforcement or renovation of lines and buildings and reconstruction and renovation according to transport development or other objective needs.

However, for a long time, when the crew carries out daily maintenance or overhaul operation on the railway line, materials (such as fishplates, backing plates, bolts and the like) and tools (such as presses, tamping machines, crowbars and the like) required by the site are carried by the staff in a hand-carrying and shoulder-carrying manner, and when the operation site is a little far away, the reciprocating process further increases the fatigue of the staff, and the labor intensity of the crew is increased.

To this end, i have developed and proposed a railway dolly, patent application No. 2019218406840, but a problem in the use is that the dolly cannot be used off the track because the wheels of the dolly are made of steel and the area of the factory without work is a hardened road surface, even a hard dirt road surface in some areas, and the steel wheels with tools can damage the road surface by the rims when used on the ground, and can easily get down and push the dolly when not being hardened, which results in a very small applicability of the dolly, after all the dolly cannot occupy the railway track for a long time, and even the tool between the office factory and the railway field needs to be pulled by a separate dolly, which is not a burden.

To this end, we developed and proposed new solutions and filed applications.

The frame 1 is a frame main body of a supporting structure, the roller 2 can be supported on a railway track, the rim 3 is limited relative to the track, the wheel is separated from the track in the running process, the object placing table 4 is used for placing heavy objects such as tools and materials, the supporting wheel 9 capable of controlling up-and-down movement is used for enabling the track tool vehicle for maintenance to be used when the track tool vehicle runs on the ground, the common hardened ground can not be damaged due to supporting through the supporting wheel 9, and the phenomenon that the roller 2 sinks into the ground to cause running difficulty when the roller runs on soft road surfaces such as mud and the like, for example, the supporting wheel 9 made of nylon materials with larger width is prevented. Meanwhile, when the track tool vehicle for overhauling is used on a railway track, the supporting wheels 9 are folded upwards, so that the supporting wheels 9 are prevented from interfering with sleepers, connecting pieces or accumulated objects on the railway to influence the advancing. Particularly, if the supporting wheels 9 are not folded, the track change of the track tool vehicle for overhauling on the railway is influenced. The connecting column 5 supports the handle 6, so that an operator can conveniently hold the handle 6 and move the rail tool car for overhauling.

In order to make the handle 6 comfortable when being held by a worker and have better holding feeling to facilitate force application, the handle 6 is sleeved with an elastic handle sleeve 29, the outer surface of the handle sleeve is provided with patterns for increasing friction force, and meanwhile, the handle can also protect the hand.

In order to further facilitate the workers to pull the rail tool car for maintenance off or onto the rail, the front and rear sides of the frame 1 are respectively provided with a lifting bar 26 rigidly connecting the left and right mounting seats 7, and a gap is formed between the lifting bar 26 and the object placing table 4.

The control down state can be seen in fig. 5, and the stowed state in fig. 4.

Further, in order to improve the operating performance of the up-and-down control of the support wheel 9, the upper end of the second support arm 16 is provided with a U-shaped slot, the hinge portion of the second hinge lug 15 is inserted into the U-shaped slot and is hinged with the second support arm 16, the first support arm 17 comprises two arm plates 18 which are oppositely arranged in parallel, the lower ends of the arm plates 18 are arranged at two sides of the hinge portion of the first hinge lug 14 and are hinged with the first hinge lug 14, the upper ends of the arm plates 18 are arranged at two sides of the lower end of the second support arm 16, the arm plates 18 are hinged with the lower end portion of the second support arm 16 and continue to extend towards the second hinge lug 15, two first locking holes 19 which are symmetrical with the center of the hinge portion of the first support arm 17 and the second support arm 16 are arranged on the arm plates 18, the second support arm 16 is provided with a second locking hole 20, the distance from the hinge portion of the second locking hole 20 to the first support arm 17 and the second support arm 16 is the same as the distance from the hinge portion of the first support arm 17 and the hinge portion of the second support arm 16, the second arm 16 is swung up and down to make the first locking hole 19 and the second locking hole 20 coaxial, and a locking pin 21 is provided, and the locking pin 21 can pass through the first locking hole 19 and be inserted into the second locking hole 20 when the first locking hole 19 and the second locking hole 20 are coaxial. The U-shaped cutting groove and the second hinge lug 15 are matched with each other to facilitate installation and connection, the first support arm 17 comprises two arm plates 18 which are oppositely arranged in parallel, the arm plates 18 are positioned on two sides of the second support arm 16, therefore, the arm plates 18 can smoothly avoid the second support arm 16 from being turned up and down, and the first support arm 17 and the second support arm 16 are limited by inserting the first lock hole 19 and the second lock hole 20 through the locking pin 21, so that effective support and positioning are realized. To facilitate the use of the locking pin 21, one end of the locking pin 21 has a shank 22. And an operating handle 23 coaxially connected with the hinged position of the first supporting arm 17 and the second supporting arm 16 is arranged at the hinged position. The second support arm 16 is turned up and down by holding the operating handle 23 by hand, so that the operation is convenient, the force is easy to apply, and the work is convenient.

Further, the supporting arm 8 comprises an upper arm 27 and a lower arm 28, the upper arm 27 is coaxially and rotatably connected with the lower arm 28, the upper arm 27 is provided with the seat 7, and the lower arm 28 is connected with the supporting wheel 9. Therefore, the supporting wheels 9 can swing independently, and steering is convenient when the ground travels.

Furthermore, the second arm 16 is provided with a pad 30 at the lower end thereof, and when the second arm 16 is downward and the pad 30 is supported on the mounting plate 10, the first arm 17 and the second arm 16 are in the same straight line.
