This not only has low efficiency but also cannot accurately grasp the measurement accuracy, resulting in a reduction in laying accuracy. Furthermore, there is an urgent need for a device for laying sleepers in ballastless tracks to lay sleepers in batches and ensure that the spacing between these sleepers remains within a predetermined value, improving the laying accuracy and greatly enhancing the paving efficiency.

Detailed implementation mode

[0024] The following is a description of the preferred embodiments of the present invention with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0025] The present invention discloses a ballastless track long sleeper leveling device, as Figures 1-5As shown in the figure, it includes an assembly seat 100, a scissor-type telescopic frame 200 and a plurality of clamping mechanisms 500. Among them, the assembly seat 100 is installed on the traveling vehicle, and the scissor-type telescopic frame 200 is installed on the assembly seat 100. The scissor-type telescopic frame 200 is driven to be telescopic along the length direction of the track. One end of the scissor-type telescopic frame 200 is fixedly connected to the assembly seat 100, and the other end of the scissor-type telescopic frame 200 is slidably connected to the assembly seat 100. The plurality of clamping mechanisms 500 described in the present utility model are installed at intervals along the telescopic direction of the scissor-type telescopic frame 200 at the lower end of the scissor-type telescopic frame 200. Each clamping mechanism 500 is connected with a vertical driving member 300. Each vertical driving member 300 is connected to the scissor-type telescopic frame 200, and the upper end of the vertical driving member 300 is slidably connected to the assembly seat 100 through a telescopic member 400. The working principle and advantages of the present utility model are as follows: A plurality of hydraulic cylinders can be installed between the assembly seat 100 and the traveling vehicle. These hydraulic cylinders are arranged at intervals along the length direction of the track, and these hydraulic cylinders act synchronously to drive the assembly seat 100 to move in the vertical direction, so that the plurality of clamping mechanisms 500 move in the vertical direction. In this way, these clamping mechanisms 500 clamp or release the same number of sleepers. By controlling the extension of the scissor-type telescopic frame 200 of the present utility model, the distance between the clamping mechanisms 500 clamping the sleepers gradually becomes larger until the distance between adjacent clamping mechanisms 500 reaches a predetermined value. Then, control all the vertical driving members 300 to synchronously drive each clamping mechanism 500 vertically, so that the clamping mechanism 500 places the clamped sleeper at a predetermined position. To sum up, by controlling the telescopic movement of the scissor-type telescopic frame 200 of the present utility model, the distance change between adjacent clamping mechanisms 500 is consistent, thereby ensuring that the distance adjustment between adjacent sleepers is consistent. When the distance between two adjacent sleepers reaches a predetermined value, the distance between other adjacent sleepers on the device also reaches the predetermined value, so there is no need to measure the distance of each sleeper separately. Therefore, the present utility model can efficiently lay sleepers in batches, ensure that the distance between these sleepers remains within the predetermined value, improve the laying accuracy, and greatly improve the paving efficiency.

[0026] As a preferred embodiment of the present utility model, as Figure 2As shown, the assembly seat 100 includes a guide rail 101, a first seat body 102 and a second seat body 103. Among them, the guide rail 101 extends along the length direction of the track, and the first seat body 102 and the second seat body 103 are respectively fixedly installed at both end positions of the guide rail 101. The first seat body 102 and the second seat body 103 are both connected to the traveling vehicle, or both are connected to the traveling vehicle through the above-mentioned hydraulic cylinder. A second sliding block 403 is fixed to the upper end of each telescopic member 400, and the second sliding block 403 is slidably assembled on the guide rail 101. In the process of the scissor-type telescopic frame 200 telescoping in this embodiment, the telescopic member 400 slides on the guide rail 101 accordingly. At the same time, due to the change in the vertical width generated by the telescoping of the scissor-type telescopic frame 200, the telescopic member 400 undergoes a corresponding amount of passive telescoping. The telescopic member 400 and the vertical driving member 300 in this embodiment cooperate to effectively lift the corresponding part of the scissor-type telescopic frame 200, avoiding deformation of the scissor-type telescopic frame 200 due to excessive local force when the clamping mechanism 500 clamps the sleeper. The telescopic member 400 in this embodiment includes a vertical rod 402 and a vertical tube 401. The lower end of the vertical rod 402 is detachably connected to the upper end of the vertical driving member 300. The upper end of the vertical rod 402 extends into the vertical tube 401 from the lower end of the vertical tube 401. The upper end of the vertical tube 401 is slidably connected to the guide rail 101 of the assembly seat 100 through the second sliding block 403. A connecting spring can be assembled in the vertical tube 401 in this embodiment. Both ends of the connecting spring are respectively connected to the vertical rod 402 and the vertical tube 401, so that when the vertical position of the vertical rod 402 changes in the vertical tube 401, the connecting spring stores elastic energy and limits the extreme positions of the vertical rod 402 inserted into or pulled out of the vertical tube 401.

[0027] As a preferred embodiment of the present utility model, as Figures 2-4As shown in the figure, the scissor-type telescopic frame 200 includes a scissor frame, a fixed seat 203 and a movable seat 204. Among them, the fixed seat 203 and the movable seat 204 are respectively installed at both ends of the scissor frame. The fixed seat 203 is fixedly connected to one end of the assembly seat 100. A first sliding block 205 is installed at the upper end of the movable seat 204, and the first sliding block 205 is slidably connected to the guide rail 101 of the assembly seat 100. Each vertical driving member 300 and each clamping mechanism 500 are connected to the scissor frame. Specifically, the scissor frame includes a plurality of scissor components, and these scissor components are sequentially hinged together along the length direction of the track. Each scissor component includes two groups of scissor rod groups, and these two groups of scissor rod groups are symmetrically arranged on both sides below the assembly seat 100. Each scissor rod group includes two scissor rods 201, and the middle parts of these two scissor rods 201 are hinged to each other through a hinge rod 206. The hinge rods 206 of two opposite scissor rod groups are connected in succession, and the end of each hinge rod 206 is hinged to the end of the hinge rod 206 of the adjacent scissor component. Among the plurality of scissor components described in this embodiment, a plurality of obliquely arranged driving members 202 are installed on one of the scissor components. One end of each obliquely arranged driving member 202 is hinged to a hinge rod 206 of a scissor rod group, and the other end of the obliquely arranged driving member 202 is hinged to another hinge rod 206 of the scissor rod group. Generally, the obliquely arranged driving member 202 is an obliquely arranged oil cylinder. By controlling the telescopic movement of the obliquely arranged oil cylinder, the scissor-type telescopic frame 200 is telescoped. The telescopic mode and principle of the scissor-type telescopic frame 200 are the same as those of the scissor-type lifting platform in the laid-down state, and will not be elaborated here.

[0028] As a preferred embodiment of the present invention, as Figures 3-5As shown in the figure, the vertical driving member 300 includes a vertically arranged hydraulic cylinder. The cylinder body 301 of the hydraulic cylinder is connected to the hinge rod 206 corresponding to the scissor-type telescopic frame 200 through the first connecting ear 303. The cylinder rod 302 of the hydraulic cylinder is drivingly connected to the corresponding clamping mechanism 500 through the second connecting ear 304, and the clamping mechanism 500 is connected to the cylinder body 301 of the hydraulic cylinder.

Each transmission arm body 501 is hinged with a transfer arm 504 through the hinge shaft 505. The mutually approaching ends of the two transfer arms 504 are hinged on the connecting rod 307, and the connecting rod 307 is connected to the second connecting ear 304 on the cylinder rod 302. In this embodiment, the scissor shaft 503 is fixedly installed on the transfer seat 506. A third connecting ear 305 is constructed on the cylinder body 301 of the hydraulic cylinder. The transfer seat 506 is detachably connected to the third connecting ear 305 on the cylinder body 301 through the transfer plate 306. The working principle and advantages of this embodiment are as follows: In this embodiment, the cylinder rod 302 of the hydraulic cylinder is used to drive the connecting rod 307 to move in the vertical direction, so that the connecting rod 307 drives the two transfer arms 504 at its respective ends to act, so that the two transfer arms 504 drive the two transmission arm bodies 501 of the clamping claws to act, so that the clamping opening between the two clamping arm bodies 502 becomes smaller or larger, thereby realizing the function of clamping or releasing the end of the sleeper, and finally cooperating with the telescopic movement of the scissor-type telescopic frame 200 to achieve the purpose of laying sleepers in batches at a fixed distance.
