Description

Technical Field

[0001] This utility model belongs to the field of track maintenance and adjustment construction technology, and relates to an auxiliary clamp for disassembling and assembling rail leveling pads. Background Technology

[0002] In the metallurgical machinery industry and rail transit sector, one of the tasks in rail maintenance is rail leveling. Leveling involves removing the mounting bolts at uneven sections of the rail surface, lifting the rail, and adjusting the existing shims underneath to reduce or eliminate unevenness. Currently, the most labor-intensive part of this work is lifting the rail. Previously, this was done by hammering a pre-prepared wedge into the rail, raising the rail support. Then, depending on the required height, shims were replaced or added. The wedges were then removed, the rail mounting bolts were tightened, and the leveling was measured. In practice, if the support is not suitable, the rail sometimes needs to be lifted and the shims adjusted multiple times. Lifting the rail using a hammer and wedge method is labor-intensive, and when working at heights or near edges, there is a risk of workers, tools, and wedges falling. Furthermore, removing the wedges is time-consuming and labor-intensive.

[0003] Therefore, in order to avoid the above problems and risks, it is necessary to find a track clamping tool to simplify the track leveling and support operation, reduce labor intensity, and reduce operational safety risks. Utility Model Content

[0004] The purpose of this utility model is to address the problems existing in the prior art by providing an auxiliary clamp for the disassembly and assembly of rail leveling pads. This solves the problems of high labor intensity and the risk of personnel, tools, and wedges falling and causing injuries in the existing rail leveling operation methods, which involve lifting the rail and using a hammer to strike the wedge plate.

[0005] Therefore, the present invention adopts the following technical solution:

[0006] An auxiliary clamp for disassembling and assembling rail leveling pads includes a first crossbar with clamping rods symmetrically provided at both ends of the first crossbar and the two are movably connected. A second crossbar is provided below the first crossbar, and connecting rods are symmetrically provided at both ends of the second crossbar. The two ends of the connecting rods are movably connected to the first crossbar and the second crossbar, respectively. A hydraulic jack is provided at the top of the second crossbar, and its top is in contact with the bottom of the first crossbar.

[0007] Furthermore, the first crossbar and the second crossbar are arranged in parallel.

[0008] Furthermore, the clamping rod is L-shaped and has a wedge at its bottom.

[0009] Furthermore, the wedges of the adjacent clamping rods are in a clamping position.

[0010] Furthermore, a lifting lug is provided at the top of the first crossbar.

[0011] The beneficial effects of this utility model are as follows:

[0012] This invention employs a small-sized hydraulic jack to drive a linkage mechanism, which generates clamping force. The clamping end is designed as a sharp wedge structure, replacing the method of manually striking the wedge plate to lift the track. Specifically, this invention has two advantages: firstly, the hydraulic pressure is much greater than the hammering force, making it easier for the wedge plate to be driven in; secondly, the hydraulic pressure drive allows for precise control of the degree of wedging.

[0013] Furthermore, since most rail leveling operations are conducted at height, the use of this invention can reduce the risk of easily scattered parts such as wedges and hammers falling from heights. While achieving the goal of quickly supporting and lifting the rail, it can also improve construction efficiency, reduce labor intensity, and ensure operational safety. Attached Figure Description

[0016] The technical solution of this utility model will be described below with reference to the accompanying drawings and implementation methods.

[0017] like Figure 1 As shown, an auxiliary clamp for disassembling and assembling a rail leveling pad includes a first horizontal bar 1, with a lifting lug 7 at the top; clamping rods 2 are symmetrically arranged at both ends of the first horizontal bar 1 and are movably connected; the clamping rods 2 are L-shaped and have wedge feet 6 at their bottom, with the wedge feet 6 of adjacent clamping rods 2 clamping each other; a second horizontal bar 3 is arranged below the first horizontal bar 1; specifically, the first horizontal bar 1 and the second horizontal bar 3 are arranged in parallel.

[0018] The second crossbar 3 is symmetrically provided with connecting rods 4 at both ends. The two ends of the connecting rods 4 are movably connected to the first crossbar 1 and the second crossbar 3 respectively. The top of the second crossbar 3 is provided with a hydraulic jack 5, and its top is in contact with the bottom of the first crossbar 1.

[0019] In use, this utility model is secured to the rail 8 that needs to be lifted. The hydraulic jack 3 is operated to press down the first crossbar 1 and the second crossbar 3. The clamping rod 2 pulls the two wedge feet 6 together, creating a clamping force. Under this clamping force, the wedge feet 6 are inserted between the rail 8 and the rail beam 9, lifting the rail 8 away from the rail beam 9 and creating a gap. Then, the rail 8 support plate is installed or adjusted to level the rail 8. After the rail 8 is supported, the hydraulic jack 3 is depressurized, and a small pry bar is used to pull out the wedge feet 6. If the adjustment is not satisfactory the first time, the above operation can be repeated until the rail 8 is leveled.
