Description

Technical Field

[0001] This utility model relates to the technical field of height adjustment devices, specifically a height adjustment device for railway freight car couplers. Background Technology

[0002] The railway freight car coupler height adjustment device is a special equipment used to adjust the vertical height of the coupler centerline to the rail surface. Its main height adjustment device is based on the jack. The core function of the railway freight car coupler height adjustment device is to ensure that the coupler height meets the technical standards.

[0003] The existing coupler height adjustment devices have the problem that it is inconvenient to change the height adjustment point;

[0004] The reason for this problem is that when the height of the railway freight car coupler does not meet the standard, a jack device needs to be placed under the coupler whose height needs to be adjusted. Then, the jack is turned on to push the coupler upwards to make the coupler height meet the connection standard. However, the coupler is heavy and large in size. Most couplers only need to be adjusted in part. Before using the jack, the base needs to be reinforced to ensure the safety of the jack during use. This means that the support point of the jack cannot change with the adjustment position during the adjustment of large couplers, resulting in a large deviation between the adjustment point and the support point, which affects the adjustment effect of the coupler. Therefore, we propose a railway freight car coupler height adjustment device. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model proposes a railway freight car coupler height adjustment device, which solves the problem that the existing coupler height adjustment devices are inconvenient to change the height adjustment point.

[0007] Preferably, a sliding frame is slidably provided on the outside of the support plate, and the movable roller is rotatably disposed inside the sliding frame.

[0008] Preferably, a mounting frame is fixedly connected to the lower surface of the sliding frame, and a threaded rod is rotatably connected inside the mounting frame, the threaded rod being rotatably connected to the lower surface of the sliding frame.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] This application provides a railway freight car coupler height adjustment device, which solves the problem that existing coupler height adjustment devices are inconvenient to change the height adjustment point.

[0021] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0022] According to the appendix Figure 1-4 As shown, the device includes a height adjuster body 1, and a control mechanism is provided on the outside of the height adjuster body 1. The control mechanism includes a support plate 2, which is movably disposed at the top of the height adjuster body 1. A movable roller 201 is movably disposed outside the support plate 2. The movable roller 201 changes the support point position by moving. A movable frame 202 is movably sleeved on the outside of the movable roller 201. The movable frame 202 is used to increase the stability of the support. A locking block 205 is disposed below the movable frame 202. The locking block 205 is movably disposed below the movable roller 201 and is movably locked below the support plate 2. The locking block 205 is used to fix the position of the movable roller 201.

[0023] A sliding frame 208 is slidably mounted on the outside of the support plate 2. A movable roller 201 is rotatably mounted inside the sliding frame 208. A mounting frame 207 is fixedly connected to the lower surface of the sliding frame 208. A threaded rod 206 is rotatably connected inside the mounting frame 207. The threaded rod 206 is rotatably connected to the lower surface of the sliding frame 208.

[0024] The threaded rod 206 is externally threaded with a movable plate 203. The movable plate 203 is movably sleeved on the outside of the mounting frame 207. The locking block 205 is fixedly connected to the outside of the movable plate 203. The two sides of the movable plate 203 are fixedly connected with a sleeve frame 204. The sleeve frame 204 is movably sleeved on the outside of the support plate 2. The movable frame 202 is fixedly connected to the top of the sleeve frame 204. The lower surface of the support plate 2 is fixedly connected with a rack 209. The locking block 205 is movably locked on the outside of the rack 209.

[0025] By adjusting the position of the moving roller 201, the sliding frame 208 will slide outside the support plate 2. The sliding frame 208 will then move the threaded rod 206, the moving plate 203, and the movable frame 202 until the moving roller 201 reaches the desired height for the coupler. Then, rotating the threaded rod 206 will move the moving plate 203 upwards. The moving plate 203 will then move the locking block 205 upwards, causing the movable frame 202 and the connecting frame 204 to move upwards along with the moving plate 203 until the movable frame 202 is higher than the moving roller 201. At this point, the locking block 205 will be engaged with the outside of the rack 209. The moving roller 201 reduces friction caused by the sliding frame 208 contacting other structures, facilitating the movement of the sliding frame 208. The movement of the movable frame 202, followed by moving it above the moving roller 201, increases the stability of the height adjustment process. Simultaneously, the movement of the movable frame 202 also moves the locking block 205 to fix the entire control mechanism. Finally, the height adjuster body 1 is activated, moving the movable frame 202 to support and adjust the position of the coupler that needs to be raised. The sliding frame 208 and the moving roller 201 support the support point. Then, the threaded rod 206 is rotated, simultaneously moving the locking block 205 and the movable frame 202. This fixes the structure of the sliding frame 208 while moving the movable frame 202 upwards, thereby increasing the stability of the height adjustment point support after the movement. This increases the flexibility of the height adjuster body 1 without affecting the stability of the height adjustment support.

[0026] In summary, compared with existing technologies, it has the following beneficial effects:

[0027] By moving the position of the moving roller 201 and the sliding frame 208 until the position of the moving roller 201 is moved to the position where the coupler needs to be adjusted, the threaded rod 206 is rotated to drive the moving plate 203 and the locking block 205 to move upward until the position of the movable frame 202 is higher than the position of the moving roller 201. At this time, the locking block 205 will also be movably locked to the outside of the rack 209. Finally, the height adjuster body 1 is activated to drive the movable frame 202 to support and adjust the position where the coupler needs to be adjusted. The sliding frame 208 and the moving roller 201 support the support point. Then, the threaded rod 206 is rotated to drive the locking block 205 and the movable frame 202 to move. While fixing the structure of the sliding frame 208, the movable frame 202 is moved upward, thereby increasing the stability of the height adjustment point support after the movement, increasing the flexibility of the height adjuster body 1 in use, and not affecting the stability of the height adjustment support of the height adjuster body 1.
