Description

Technical Field

[0001] This utility model relates to the technical field of maintenance tools for controllable parking devices, specifically an expansion and tightening combination tooling for the WKT-1 type controllable parking device. Background Technology

[0002] In modern railway transportation systems, the controllable stop device is a crucial parking braking device. Due to the high-frequency friction between the brake rail and the wheels over a long period, surface wear is inevitable. As wear intensifies, the braking performance of the brake rail gradually declines, directly affecting the safety and reliability of train stops. Currently, the industry commonly uses a method of adding U-shaped adjusting clips and wear-resistant pads to the flag block of the controllable stop device's support arm. By precisely adjusting the contact area between the brake rail and the wheels, the braking efficiency of the brake rail is restored to the design standard.

[0003] However, in actual maintenance operations, the lack of suitable specialized tools makes it impossible to effectively expand or tighten the brake rails, resulting in significant difficulties in installing U-shaped adjusting clips and wear-resistant pads. Workers not only expend considerable time and energy during operation but also face problems such as cumbersome procedures and inaccurate positioning, severely restricting equipment maintenance efficiency, increasing labor costs, and posing potential hazards to the efficient and safe operation of railway transportation. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the purpose of this invention is to provide an expansion and tightening combination tooling for a controllable parking device, so as to solve the problem of the inability to effectively expand or tighten the brake rail.

[0005] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0006] An expansion and tightening assembly for a controllable parking device mainly includes a first hollow column, with slots on both sides of the first hollow column. A first cylinder is fitted to both sides of the first hollow column. A second hollow column is fixedly connected to the inner wall of the first cylinder, with its surface fitting against the inner wall of the first hollow column. A first horizontal plate is fixedly connected to the inner wall of the second hollow column, with a threaded hole inside the first horizontal plate. A vertical plate is fixedly connected to the upper surface of the first hollow column, and a second horizontal plate is fixedly connected to the upper surface of the vertical plate. A first circular hole is formed on the upper surface of the first hollow column, and a second circular hole is formed inside the second horizontal plate. Fixing bolts are fitted to the inner wall of the second circular hole and the upper surface of the second horizontal plate, with their surfaces threadedly connected to the inner wall of the threaded hole. A threaded column is fixedly connected to the inner wall of the second hollow column, with a fixing nut threadedly connected to its surface. A limiting block is sleeved on the surface of the threaded column, located between the first cylinder and the fixing nut.

[0007] The present invention is further configured such that the threaded hole is located outside the second hollow column, and the axis of the threaded hole coincides with the axis of the first circular hole.

[0008] The present invention is further configured such that a first positioning groove is provided on the side of the threaded column, a positioning post is fitted to the inner wall of the first positioning groove, and the upper and lower sides of the positioning post are fixedly connected to the inner wall of the limiting block.

[0009] The present invention is further configured such that a second cylinder is fixedly connected to the inner wall of the first hollow column, and a third cylinder is fitted to both the left and right sides of the second cylinder and the inner wall of the first hollow column. A third circular hole is provided on both the upper and lower sides of the third cylinder, and a cylinder is fixedly connected to the inner wall of the third circular hole. A strip-shaped hole is provided at the bottom of the first hollow column, and the inner wall of the strip-shaped hole is fitted to the surface of the cylinder.

[0010] The present invention is further configured such that a second positioning groove is provided on the side of the first horizontal plate, and the inner wall of the second positioning groove is in contact with the surface of the cylinder.

[0011] The present invention is further configured such that the center of the first horizontal plate coincides with the axis of the second hollow column, and the width of the first horizontal plate is smaller than the inner diameter of the third cylinder.

[0012] Compared with the prior art, this utility model has the following advantages:

[0013] 1. This utility model comprises a first hollow column, a slot, a first cylinder, a second hollow column, a first horizontal plate, a threaded hole, a vertical plate, a second horizontal plate, a first round hole, a second round hole, a fixing bolt, a threaded column, a fixing nut, and a limiting block. When the second hollow column is removed from the first hollow column, the slot abuts against the inner beam of the brake rail, creating a gap between the brake rail and the support arm flag block, facilitating the installation of the U-shaped adjusting clip and the wear-resistant pad. Simultaneously, when the second hollow column is fixed inside the first hollow column, the limiting block presses against the friction surface of the brake rail, tightening the brake rail and ensuring a tight fit between the brake rail, the U-shaped adjusting clip, the wear-resistant pad, and the support arm flag block. This expansion and tightening assembly effectively expands or tightens the brake rail, simplifying the installation process of the U-shaped adjusting clip and the wear-resistant pad and improving the maintenance efficiency of the controllable parking device.

[0014] 2. This utility model is provided with a second cylinder, a third cylinder, a third circular hole, a cylinder, a strip hole, and a second positioning groove. When the user hammers the cylinder, the hammering force is applied to the second hollow column through the second cylinder, the third cylinder, and the first horizontal plate. At this time, the hammering force can loosen the second hollow column from the first hollow cylinder, making it easier for the user to remove the second hollow column stuck in the first hollow column. At the same time, when the second hollow column is inserted into the first hollow column, the second positioning groove and the cylinder can accurately align the threaded hole with the second circular hole, making it easier for the user to screw the fixing bolt into the threaded hole.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 As shown, the expansion and tightening assembly tooling for a controllable parking device of this utility model mainly includes a first hollow column 1, with slots 2 on both the left and right sides of the first hollow column 1, and a first cylinder 3 fitted to both the left and right sides of the first hollow column 1. A second hollow column 4 is fixedly connected to the inner wall of the first cylinder 3, and the surface of the second hollow column 4 is fitted to the inner wall of the first hollow column 1. A first horizontal plate 5 is fixedly connected to the inner wall of the second hollow column 4, and a threaded hole 6 is opened inside the first horizontal plate 5. A vertical plate 7 is fixedly connected to the upper surface of the first hollow column 1, and a second horizontal plate 8 is fixedly connected to the upper surface of the vertical plate 7. A first circular hole 9 is opened on the upper surface of the first hollow column 1. The interior of the second horizontal plate 8 has a second circular hole 10. The inner wall of the second circular hole 10 and the upper surface of the second horizontal plate 8 are fitted with fixing bolts 11. The surface of the fixing bolts 11 is threadedly connected to the inner wall of the threaded hole 6. The inner wall of the second hollow column 4 is fixedly connected with a threaded column 12. The surface of the threaded column 12 is threadedly connected with a fixing nut 13. The surface of the threaded column 12 is fitted with a limiting block 14. The limiting block 14 is located between the first cylinder 3 and the fixing nut 13. The side of the threaded column 12 has a first positioning groove 15. The inner wall of the first positioning groove 15 is fitted with a positioning post 16. The upper and lower sides of the positioning post 16 are fixedly connected to the inner wall of the limiting block 14.

[0030] The threaded hole 6 is located outside the second hollow column 4, and the axis of the threaded hole 6 coincides with the axis of the first circular hole 9.

[0031] It should be noted that when the slot 2 abuts against the inner beam of the brake rail, the cooperation between the first hollow column 1 and the slot 2 creates a gap between the brake rail and the support arm flag block, facilitating the installation of the U-shaped adjusting clip and the wear-resistant pad. When the second hollow column 4 is inserted into the first hollow column 1, the second hollow column 4 can be fixed inside the first hollow column 1 by screwing the fixing bolt 11 into the threaded hole 6. When the limiting block 14 presses against the friction surface of the brake rail, the brake rail can be tightened by the expansion and tightening combination tooling, and the brake rail, U-shaped adjusting clip, wear-resistant pad and support arm flag block can fit tightly together. The limiting block 14 on the second hollow column 4 can be quickly replaced by the cooperation of the threaded column 12 and the fixing nut 13. At the same time, the limiting block 14 on the threaded column 12 can be positioned by the cooperation of the first positioning groove 15 and the positioning column 16.

[0032] The inner wall of the first hollow column 1 is fixedly connected to the second cylinder 17. The left and right sides of the second cylinder 17 and the inner wall of the first hollow column 1 are fitted with the third cylinder 18. The upper and lower sides of the third cylinder 18 are provided with the third circular hole 19. The inner wall of the third circular hole 19 is fixedly connected to the cylinder 20. The bottom of the first hollow column 1 is provided with the strip hole 21. The inner wall of the strip hole 21 is fitted with the surface of the cylinder 20. The side of the first horizontal plate 5 is provided with the second positioning groove 22. The inner wall of the second positioning groove 22 is fitted with the surface of the cylinder 20.

[0033] The center of the first horizontal plate 5 coincides with the axis of the second hollow column 4, and the width of the first horizontal plate 5 is smaller than the inner diameter of the third cylinder 18.

[0034] It should be noted that when the user hammers the cylinder 20, the hammering force can be applied to the second hollow column 4 through the second cylinder 17, the third cylinder 18 and the first horizontal plate 5. At this time, the hammering force can loosen the second hollow column 4 from the first hollow cylinder, making it easier for the user to remove the second hollow column 4 stuck in the first hollow column 1. At the same time, when the second hollow column 4 is inserted into the first hollow column 1, the second positioning groove 22 and the cylinder 20 can accurately align the threaded hole 6 with the second round hole 10, making it easier for the user to screw the fixing bolt 11 into the threaded hole 6.

[0035] The working principle of this utility model is as follows: First, unscrew the fixing bolt 11 from the threaded hole 6 and pull the second hollow column 4 out from the first hollow column 1. Then, press the slot 2 against the inner beam of the brake rail and reduce the distance between the support arm flag blocks on both sides of the controllable parking device through the hydraulic system in the controllable parking device. At this time, the cooperation between the first hollow column 1 and the slot 2 can create a gap between the brake rail and the support arm flag block. Then, install the U-shaped adjusting card and the wear-resistant pad on the support arm flag block.

[0036] After the U-shaped adjusting clip and wear-resistant pad are installed on the support arm flag block, remove the first hollow column 1 between the two brake rails. Then, insert the second hollow column 4 into the first hollow column 1. Next, pass the fixing bolt 11 through the second round hole 10 and the first round hole 9, and screw it into the threaded hole 6. At this time, the second hollow column 4 is fixed in the first hollow column 1 by the cooperation of the fixing bolt 11 and the threaded hole 6. Then, press the inner side of the two limit blocks 14 against the friction surface of the brake rail (the distance between the two limit blocks 14 is the standard distance between the two brake rails, and at the same time, it can be checked whether the added wear-resistant pad matches the wear of the brake rail). By the tension of the brake spring in the controllable parking device, the brake rail, U-shaped adjusting clip, wear-resistant pad and support arm flag block are tightly fitted. At this time, the position of the brake rail can be fixed. After the position of the brake rail is fixed, the expansion and tightening assembly tooling is removed from the brake rail.

[0037] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
