Description

Technical Field

[0001] The present invention relates to the technical field of high - speed railway construction equipment, and particularly to a multi - plate type universal fixture for embedded sleeves of ballastless tracks. Background Technique

[0002] The ballastless track is an important part of high - speed railways, and the preparation of the ballastless track consists of multiple track slabs. The commonly used one is the CRTS III - type ballastless track slab. There are 4 types of high - speed railway CRTS III - type ballastless track slabs, namely P5600, P4925, P4856, and P3710 (rarely appears and is not considered). Different combinations of different slab types form different beam - type ballastless track beds. The base is connected to the beam surface through embedded sleeves on the beam surface. Similarly, according to different track slab types, embedded holes need to be opened at different positions.

[0003] In the prior art, for example, a multi - plate type universal fixture for embedded sleeves of ballastless tracks disclosed in a Chinese patent with the publication number CN119321071A includes fixture A and fixture B. The fixture A includes a first bottom plate, and two first vertical rods are fixedly connected to the top of the first bottom plate. Two first cross rods are fixedly connected to the left end of the top of the first bottom plate. When the cast - in - place beam is cast integrally, fixture A and fixture B are connected by bolts to form an integral body. The starting and ending positions of the ballastless track axis, the first protective plate, the first cross rod, the first bottom plate, the first vertical rod, the second vertical rod, the second bottom plate, and the second cross rod are measured on - site. Two people lift and place fixture A and fixture B to the designed position to align with the starting embedded hole, and the embedded sleeve is pre - buried according to the hole position number of the reserved hole. When constructing the next slab, the connecting holes (P5600 continuation, P4925 continuation, P4856 continuation) are connected and aligned with the embedded sleeve of the upper slab through M16 bolts, and then the embedding of the next base is started. When using the cantilever segmental construction method, fixture A and fixture B are used separately and alternately.

[0004] However, this patent still has deficiencies. When assembling fixture A and fixture B, manual docking is still required, and the docking accuracy is easily interfered, which has an adverse impact on the construction quality. Therefore, a multi - plate type universal fixture for embedded sleeves of ballastless tracks is proposed to solve the above problems. Summary of the Invention

[0005] In order to solve the above - mentioned technical problems, the present invention proposes a multi - plate type universal fixture for embedded sleeves of ballastless tracks. By setting connecting parts and auxiliary fixing parts, it can help fixture A and fixture B to be more accurately docked, reduce human errors, and ensure the project quality.

[0006] The technical solution for achieving the purpose of the present invention is: a multi - plate type universal fixture for embedded sleeves of ballastless tracks, including fixture A and fixture B. Auxiliary fixing parts are arranged on the sides of fixture A and fixture B that are away from each other. It also includes;

[0007] Two fixing seats are respectively fixedly connected to the sides of the fixture A and the fixture B that are away from each other, and the auxiliary fixing member is connected to the fixing seat;

[0008] A connecting member, the connecting member includes a plugging bin fixedly connected to one side of the fixture A, and a plugging block fixedly connected to the same side of the fixture B and adapted to the plugging bin, and a plugging slot is penetrated through the plugging block.

[0009] In some embodiments, the auxiliary fixing member includes an auxiliary fixing column slidably connected to one side of the fixing seat, and a fixing pressing plate is fixedly connected to one end of the auxiliary fixing column.

[0010] In some embodiments, an auxiliary fixing bolt is rotatably connected to one side of the fixing pressing plate, the auxiliary fixing bolt is screwed to one side of the fixing seat, and the upper surface of the fixing pressing plate is slidably connected to the inner top wall of the fixing seat.

[0011] In some embodiments, the connecting member further includes a clamping column slidably connected to one side of the plugging bin, a limiting block is fixedly connected to one end of the clamping column, and a separating plate is fixedly connected to the other end of the clamping column.

[0012] In some embodiments, a spring is fixedly connected to the inner wall of the plugging bin, the spring is sleeved on the surface of the connecting column, and the other end of the spring is fixedly connected to one side of the limiting block.

[0013] Compared with the prior art, the present invention has the following remarkable advantages:

[0014] Firstly: in the present invention, through the provided connecting member, when the fixture A and the fixture B are docked, the plugging block is inserted into the plugging bin. When the plugging block contacts the limiting block, the spring will be compressed. As the plugging block goes deeper, when it reaches the position of the plugging slot of the plugging block, the spring resets and pushes the limiting block into the plugging slot to fix the plugging block; it can quickly and accurately dock the two fixtures, reduce human error, speed up the docking speed, and ensure the construction quality;

[0015] Secondly: in the present invention, through the provided auxiliary fixing member, when it is necessary to fix the fixture to the template, rotate the auxiliary fixing bolt, and the auxiliary fixing bolt drives the fixing pressing plate to contact both sides of the template, making the connection between the fixture and the template tighter, further ensuring the accuracy of the position of the fixture and reducing errors;

[0016] It solves the problem that the traditional fixture needs to be manually docked, which is prone to errors and has an adverse impact on the construction quality. Brief Description of the Drawings
