Description

Technical Field

[0001] The utility model relates to the technical field of train maintenance, in particular to a modified welding and repair rack for a coupler swing block. Background Technique

[0002] The swing block is one of the key components in the coupler system. Its function is to buffer the impact force during train operation and ensure the stable connection between vehicles, especially when the train starts, brakes, or passes through sections with uneven tracks. The swing block type coupler restoration device absorbs and alleviates these forces by allowing the coupler to swing within a certain range, thereby improving the riding comfort. During long-term use, the swing block will experience wear, cracks, or fractures due to frequent impacts and vibrations during train operation. These damages will reduce the performance of the coupler system and affect train operation safety. Therefore, welding and repair are required to restore or enhance its structural integrity and function.

[0003] However, during the modification of the existing swing block, generally, the operator flips the swing block by hand to adjust the angle or position of the swing block, and then performs corresponding welding and repair. The modification of one swing block usually requires multiple flipping and repetitive operations. Due to the heavy weight of the swing block, it not only results in low modification efficiency, but also causes a certain burden on the operator's body. Moreover, due to the heavy weight of the swing block, there may be a phenomenon of slipping and not being able to hold firmly, which poses a certain safety hazard to the operator.

[0023] Embodiment:

[0024] Refer to Figures 1-4, A modified welding repair rack for a coupler swing block, including a bottom plate 1, and also including: at least one set of fixed columns 2. Here, according to the actual usage situation, it is preferably two sets. The two sets of fixed columns 2 are symmetrically arranged. When in use, by setting two sets of fixed columns 2, two swing blocks can be modified simultaneously without interference with each other, which can improve the modification efficiency. The fixed columns 2 are fixed on the bottom plate 1 through brackets 201; a fixing plate 3 is arranged to be movable up and down on the fixed columns 2. Material boxes 304 are fixedly arranged on both sides of the fixing plate 3, which is convenient for taking materials required for modification, such as welding rods, adding blocks, etc. An installation plate 4 is rotatably arranged on the fixing plate 3. An installation cylinder 303 is fixedly arranged on the top of the fixing plate 3. A limiting shaft 401 is fixedly arranged on one side surface of the installation plate 4. The limiting shaft 401 is rotatably arranged in the installation cylinder 303. And a clamping assembly for clamping the swing block is arranged on the installation plate 4. A limiting assembly for restricting the rotation of the limiting shaft 401 is arranged on the installation cylinder 303. When in use, by rotatably arranging the installation plate 4 on the fixing plate 3, and then fixing the swing block on the installation plate 4 through the clamping assembly, it is convenient to fix the swing block during modification. Moreover, through the limiting assembly, the angle or position of the installation plate 4 and the swing block can be adjusted, improving the modification efficiency and reducing the labor intensity.

[0025] Refer to Figures 1-3 , The clamping assembly can use a cylinder or a hydraulic cylinder to clamp and fix the swing block. Here, we design the clamping assembly as: a first clamping plate 403 and a second clamping plate 404 are respectively fixedly arranged on the other side surface of the installation plate 4. And a first screw rod 5 is threadedly connected to the second clamping plate 404. A clamping block 501 for clamping the swing block is rotatably arranged at one end of the first screw rod 5. When in use, by placing the swing block on the first clamping plate 403, and then rotating the first screw rod 5 to make the clamping block 501 approach the swing block, the swing block can be fixed on the first clamping plate 403, preventing the swing block from moving during the modification process and affecting the modification effect.

[0026] Refer to Figures 1-3 , A handle 502 is fixedly arranged at the other end of the first screw rod 5. And the first clamping plate 403 and the second clamping plate 404 are symmetrically arranged. When in use, by fixedly arranging a handle 502 on the first screw rod 5, it is convenient to drive the first screw rod 5 to rotate, and then drive the clamping block 501 to clamp, improving the modification efficiency.

[0027] Refer to Figure 1 , Figure 3 and Figure 4, the limiting component can fix the limiting shaft 401 in the mounting cylinder 303 by bolts. Here, we preferably use a pin 6 as the limiting component. A plurality of groups of pin holes 402 are evenly formed on the limiting shaft 401. The number of groups of pin holes 402 is two to ten groups, preferably eight groups, and the eight groups are evenly distributed in a circle. Through holes corresponding to the pin holes 402 are formed on the mounting cylinder 303. The pin 6 is inserted through the through hole and extends into the pin hole 402. During use, the pin 6 is pulled out from the pin hole 402 and the through hole in sequence, and then the mounting plate 4 is rotated by hand to adjust the angle of the swing block. After the adjustment is completed, the pin 6 is inserted through the through hole into the pin hole 402 at the current position. The adjustment is convenient and the fixing effect is reliable, which can improve the transformation efficiency.

[0028] Refer to Figures 1-3 , a lifting column 301 is fixedly arranged at the bottom of the fixing plate 3. The lifting column 301 is slidably arranged in the fixing column 2, and the cross section of the lifting column 301 is rectangular. The axis of the lifting column 301 coincides with the axis of the fixing column 2. During use, by fixedly arranging the lifting column 301 at the bottom of the fixing plate 3, the height of the fixing plate 3 can be adjusted according to the height of the worker, improving the scope of use.

[0029] Refer to Figures 1-3 , a second screw rod 7 is threadedly connected to the fixing column 2. A plurality of groups of threaded holes 302 are formed on the lifting column 301. The number of groups of threaded holes 302 is two to fifteen groups, preferably ten groups, and the ten groups are equidistantly distributed along the axis of the lifting column 301. The second screw rod 7 is threadedly connected to the threaded hole 302, and a knob 701 is fixedly arranged on the second screw rod 7. During use, the second screw rod 7 is driven to rotate by the knob 701, and it is screwed off from the lifting column 301. Then the height of the fixing plate 3 can be adjusted. After the height adjustment is completed, the second screw rod 7 is threadedly connected to the threaded hole 302 at the current position again, and the lifting column 301 can be fixed in the mounting cylinder 303, improving the use effect.
