Description

Technical Field

[0001] The invention relates to the technical field of road sleeper compression test, in particular to a compression test device for sleeper production. Background Art

[0002] Railroad sleepers, also known as railroad ties, are also a type of railway component. However, they're made of more than just wood, so the term "railway sleeper" is more scientific. While their uniform appearance may seem unremarkable, they serve a significant purpose. They support the rails, maintain their position, and transfer the immense pressure from the rails to the trackbed.

[0003] During railway operation, the track has curved sections in addition to straight sections. In the curved and straight sections, the direction of gravity of the train relative to the horizontal sleepers and the inclined sleepers is different, resulting in different pressures on the straight and curved sections, and the pressure directions are also different. The existing pressure testing device generally places the sleepers horizontally on the workbench when performing pressure testing on sleepers. This method is suitable for side views of sleepers at the straight end, but there is no device for pressure testing sleepers set in a curved section environment, making the detection incomplete. For this reason, we propose a compression testing device for sleeper production. Summary of the Invention

[0031] See also Figure 4 and Figure 6-Figure 7 The first limiting assembly 13 shown in the figure includes a first telescopic rod 14 connected and fixed to the baffle on the workbench 1. A second movable groove 15 is formed on the first fixing plate 7. The end of the first telescopic rod 14 passes through the second movable groove 15 and is fixedly connected to a vertically distributed limiting sleeve 16. A second telescopic rod 17 is fixedly connected to the outer surface of the pressure column 4. The end of the second telescopic rod 17 is fixedly connected to a vertically distributed third telescopic rod 18. The third telescopic rod 18 is fixedly connected to the first telescopic rod 14. Please refer to Figure 3-Figure 5 The second limiting assembly 19 shown in the figure includes a limiting ring 20 fixedly connected to the outer surface of the rotating sleeve 9, and the outer surface of the limiting ring 20 is rotatably connected to a limiting collar 21 with a U-shaped vertical cross-section, and a connecting plate 22 is fixedly connected between the limiting collar 21 and the first fixed plate 7.

[0032] See also Figure 2-Figure 3 The rotating assembly 23 shown in the figure includes a hydraulic device 24 embedded in the workbench 1, and the piston rod of the hydraulic device 24 passes through the workbench 1 and is pressed against the bottom support plate 3. The piston rod of the hydraulic device 24 is rotatably connected to the fourth telescopic rod 25, and the end of the fourth telescopic rod 25 is fixedly connected to a circular plate 26 that rotates in the workbench 1. A gear 27 is provided under the first telescopic rod 14, and a rotating rod 28 is fixedly connected to the central axis of the gear 27. The end of the rotating rod 28 is rotatably connected to a second fixed plate 29 that is connected and fixed to the baffle of the workbench 1. The edges of the gear 27 and the circular plate 26 are rotatably connected to a connecting rod 30 that passes through the workbench 1. The gear 27 is provided with a mating assembly 31 that cooperates with the adjustment assembly 2 to drive the limit sleeve 16 to move.

[0033] The bottom support plate 3 is fixedly connected with an insert rod 41 which is plugged into the sleeper.

[0034] In this embodiment, the sleeper is placed on the bottom support plate 3 and inserted into the reserved hole on the sleeper through the insertion rod 41. When the sleeper on the straight section of the railway needs to be detected, the center of gravity of the train and the center of the sleeper are on the vertical axis. When the sleeper on the curved section of the railway needs to be detected, the sleeper is in an inclined state. Although the train is also in an inclined state, the center of gravity of the train is unchanged relative to the train. Therefore, the connecting line formed by the center of gravity of the sleeper and the train is perpendicular to the sleeper, and the center of gravity of the train is vertically downward, forming a certain angle with the inclined sleeper. This solution is mainly for simulating the influence of the vertical center of gravity of the train on the inclined track in the case of a curved section.

[0035] The piston rod is lifted by the hydraulic device 24 to rotate the bottom supporting plate 3, and the fourth telescopic rod 25 rotates, driving the circular plate 26 to rotate in its original position. Under the action of the connecting rod 30, the gear 27 and the rotating rod 28 rotate in their original positions. The gear 27 drives the farming matching component 31 to shrink the first telescopic rod 14, thereby driving the limiting sleeve 16 to move. The moving limiting sleeve 16 drives the pressure column 4 to move, and the second telescopic rod 17 is adaptively adjusted. When the bottom supporting plate 3 rotates, the first fixed plate 7 rotates, driving the motor 8 and the rotating sleeve 9 to rotate and change positions. The rotating sleeve 9 and the threaded rod 5 are originally distributed on the same axis, and are transformed into a rotation point with the limiting ball 6 as the rotating point. The limiting ball 6 is distributed at an obtuse angle, that is, the limiting ball 6 is always kept on the vertical connection line formed by the oblique rail sleeper and the center of gravity of the train, and the pressure column 4 is always in a vertical downward state, thereby simulating the force direction and position of the rail sleeper under the bending section; the motor 8 is started, and under the stabilizing effect of the limiting collar 21, the motor 8 drives the rotating sleeve 9 to rotate, and the rotating rotating sleeve 9 rotates under the action of the limiting rod 10 and the first movable groove 11, and the limiting ball 6 rotates, so that the threaded rod 5 which is not on the same axis as the rotating sleeve 9 keeps a vertical state and rotates, and under the limitation of the second telescopic rod 17 and the limiting sleeve 16, the pressure column 4 moves downward, and the third telescopic rod 18 is adaptively extended and retracted.

[0036] It is worth noting that when testing the curved section, the influence of the inclined reserved hole position on the vertical downward force is different from that of the straight section. This method can be used to analyze the damage of the reserved hole position. In comparison, the influence of the reserved hole under pressure is greater.
