Description

Technical Field

[0001] This utility model relates to an adjustable spacing translation trolley device for static load testing of railway sleepers, belonging to the technical field of static load testing devices for railway sleepers. Background Technology

[0002] The basic principle of a railway sleeper static load testing machine: A railway sleeper static load testing machine is a device specifically designed to test the load-bearing capacity of railway sleepers. Its basic principle is to apply a certain static load to the sleepers under simulated train operation, and then evaluate the sleepers' load-bearing capacity and service life by observing and measuring the deformation and stress distribution under the load. Existing railway sleeper static load testing machines use fixed bolts to connect the crossbeams of the trolley that places the sleepers, resulting in a fixed beam spacing. This fixed beam spacing is not suitable for sleepers of varying lengths. When the sleepers are not placed correctly, alignment will not be achieved during static load testing. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide an adjustable spacing translation trolley device for static load testing of railway sleepers. This device can adjust the spacing of the crossbeams, is suitable for railway sleepers of different lengths, and ensures centering during static load compression testing.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] An adjustable spacing translation trolley device for a sleeper static load test includes two parallel supports, each with rollers at both ends. The supports are connected and fixed together by a cover plate. A first sliding rail and a second sliding rail are arranged inside each support, with the first and second sliding rails arranged opposite each other. A first crossbeam is positioned between the first and second sliding rails, and a second crossbeam is positioned between the second sliding rails. The first crossbeam can slide along the length of the support on the first sliding rail, and the second crossbeam can slide along the length of the support on the second sliding rail. Locking structures for restricting the movement of the first and second crossbeams are respectively provided on the first and second sliding rails.

[0006] Both the first and second crossbeams are rectangular parallelepipeds, and ball bearings are respectively provided on both sides of the lower surface of the first and second crossbeams.

[0007] The first and second sliding tracks are both right-angled in shape. The vertical portions of the first and second sliding tracks are connected to the bracket, and the horizontal portions of the first and second sliding tracks are in contact with the ball bearings.

[0008] The vertical portions of the first and second sliding rails are fixed to the bracket by screws and welding.

[0009] The locking structure is a U-shaped fixing clip, which is fixed on the transverse part of the first sliding track and the second sliding track. There are two U-shaped fixing clips on a single first sliding track, located on both sides of the first crossbeam. There are also two U-shaped fixing clips on a single second sliding track, located on both sides of the second crossbeam.

[0010] The U-shaped fixing clamp includes an arc-shaped plate, and a threaded rod is provided on the upper plate of the arc-shaped plate. A ring is connected to the upper end of the threaded rod, and a pressure plate is connected to the lower end of the threaded rod.

[0011] The number of balls on each side of the first and second crossbeams is two.

[0012] The upper ends of the vertical sections of the first and second sliding tracks are provided with stop sections.

[0013] The beneficial effects of this utility model are as follows: This utility model provides an adjustable spacing translation trolley device for static load testing of railway sleepers. The support has a first sliding rail and a second sliding rail inside. A first crossbeam is set between the two first sliding rails, and a second crossbeam is set between the two second sliding rails.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to illustrate the technical solution of the present invention more clearly, and should not be used to limit the protection scope of the present invention.

[0019] Example 1

[0020] like Figure 1 and Figure 2 As shown, this utility model discloses an adjustable spacing translation trolley device for a sleeper static load test, including two parallel supports 3, each with rollers 5 at both ends to facilitate trolley movement. The two supports 3 are connected and fixed by a cover plate 8, forming the main frame structure of the trolley. A first sliding rail 4 and a second sliding rail 6 are provided inside the supports 3, with the two first sliding rails 4 and two second sliding rails 6 arranged opposite to each other. A first crossbeam 2 is provided between the two first sliding rails 4, and a second crossbeam 7 is provided between the two second sliding rails 6. The first crossbeam 2 can slide along the length of the supports 3 on the first sliding rail 4, and the second crossbeam 7 can slide along the length of the supports 3 on the second sliding rail 6. The positions of the first crossbeam 2 and the second crossbeam 7 can be adjusted as needed. Locking structures are provided on the first sliding rails 4 and the second sliding rails 6 to restrict the movement of the first crossbeam 2 and the second crossbeam 7. After adjustment, the first crossbeam 2 and the second crossbeam 7 are fixed by the locking structures.

[0021] The working process of this utility model is as follows: First, remove the locking structure, and then adjust the position of the first crossbeam 2 on the first sliding rail 4 and the position of the second crossbeam 7 on the second sliding rail 6 according to the test requirements. After the adjustment is completed, install the locking structure to fix the positions of the first crossbeam 2 and the second crossbeam 7, and then conduct the subsequent static load test of the sleeper.

[0022] In this utility model, the spacing between the first and second crossbeams can be adjusted arbitrarily within the track range to meet the static load test requirements of various types of sleepers of different lengths, without the need for auxiliary work to complete the alignment when alignment cannot be achieved during the test.

[0023] Example 2

[0024] like Figure 1 and Figure 2As shown, this utility model discloses an adjustable spacing translation trolley device for a sleeper static load test, including two parallel supports 3, each with rollers 5 at both ends to facilitate trolley movement. The two supports 3 are connected and fixed by a cover plate 8, forming the main frame structure of the trolley. A first sliding rail 4 and a second sliding rail 6 are provided inside the supports 3, with the two first sliding rails 4 and two second sliding rails 6 arranged opposite to each other. A first crossbeam 2 is provided between the two first sliding rails 4, and a second crossbeam 7 is provided between the two second sliding rails 6. The first crossbeam 2 can slide along the length of the supports 3 on the first sliding rail 4, and the second crossbeam 7 can slide along the length of the supports 3 on the second sliding rail 6. The positions of the first crossbeam 2 and the second crossbeam 7 can be adjusted as needed. Locking structures are provided on the first sliding rails 4 and the second sliding rails 6 to restrict the movement of the first crossbeam 2 and the second crossbeam 7. After adjustment, the first crossbeam 2 and the second crossbeam 7 are fixed by the locking structures.

[0025] In this invention, both the first crossbeam 2 and the second crossbeam 7 are rectangular parallelepipeds. Ball bearings 1 are respectively provided on both sides of the lower surface of the first crossbeam 2 and the second crossbeam 7 to facilitate their movement. Furthermore, there are two ball bearings 1 on each side of the first crossbeam 2 and the second crossbeam 7. Both the first sliding rail 4 and the second sliding rail 6 are right-angled. The vertical portions of the first sliding rail 4 and the second sliding rail 6 are fixedly connected to the bracket 3 by screws and welding. The horizontal portions of the first sliding rail 4 and the second sliding rail 6 are in contact with the ball bearings 1. A stop is provided at the upper end of the vertical portion of the first sliding rail 4 and the second sliding rail 6 to prevent the first crossbeam 2 and the second crossbeam 7 from falling off.

[0026] like Figure 1 and Figure 3 As shown, the locking structure is a U-shaped fixing clip 9, which is fixed to the transverse portion of the first sliding rail 4 and the second sliding rail 6. There are two U-shaped fixing clips 9 on a single first sliding rail 4, located on both sides of the first crossbeam 2. Similarly, there are two U-shaped fixing clips 9 on a single second sliding rail 6, located on both sides of the second crossbeam 7. Figure 3 As shown, the U-shaped fixing clamp 9 includes an arc-shaped plate 91, with a threaded rod 93 on the upper plate of the arc-shaped plate 91. A ring 92 is connected to the upper end of the threaded rod 93, and a pressure plate 94 is connected to the lower end of the threaded rod 93. This invention allows manual rotation of the ring 92, which in turn drives the pressure plate 94 on the threaded rod 93 to move up and down. The pressure plate 94 cooperates with the upper plate of the arc-shaped plate 91, enabling the U-shaped fixing clamp 9 to be fixed and detached from the lateral portion of the first sliding rail 4 and the second sliding rail 6. When the U-shaped fixing clamp 9 is fixed on the first sliding rail 4 and the second sliding rail 6, the arc-shaped plate 91 of the U-shaped fixing clamp 9 restricts the movement of the first crossbeam 2 and the second lateral section 7.

[0027] The above are merely preferred embodiments of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
