Description

Technical Field

[0001] This utility model relates to the field of railway freight car maintenance tools, and more specifically, to a tooling for removing a railway freight car limit baffle. Background Technology

[0002] During the operation of railway freight cars, the failure of the limit baffle plate of the Type 17 coupler to detach and move out frequently occurs. After the failure is discovered on site, the extremely narrow space between the coupler shoulder and the buffer makes manual handling extremely difficult. Currently, only a temporary solution of binding with wire is used, which is very likely to detach during subsequent operation, seriously threatening the safety of train operation.

[0003] In actual maintenance work, due to the lack of specialized tools, workers attempted to widen the working space between the hook shoulder and the buffer by adding an extension rod to the jack and pressing down the coupler. However, because the distance between the hook shoulder and the buffer was too close, the jack could only be placed on one side next to the hook shoulder. Under this unconventional operating mode, the torque imbalance could easily cause the coupler to shift, leading to the jack slipping off, posing a significant occupational safety hazard and seriously endangering the personal safety of the workers. Utility Model Content

[0004] The purpose of this utility model is to solve the problems mentioned in the background art, and then to propose a tooling for removing the limit baffle of a railway freight car.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A tooling for removing a limit stop on a railway freight car includes a jack, a fixed frame, a movable frame, a connecting rib seat, a base, and a top block. The bottom of the jack is mounted on the fixed frame, and the top of the jack is connected to the movable frame, which is slidably mounted on the fixed frame, so that the movable frame can rise or fall along the fixed frame as the jack operates. A connecting rib seat is installed at the end of both the fixed frame and the movable frame. The connecting rib seat on the fixed frame is hinged to the base for locking onto the hook shoulder of the railway freight car coupler, and the connecting rib seat on the movable frame is hinged to the top block for abutting against the connection between the end wall panel and the crossbar of the railway freight car.

[0007] Furthermore, the above solution includes two slides formed on the inner side of the fixed frame, and guide rails that cooperate with the two slides on the movable frame.

[0008] Furthermore, in the above scheme, both the slide and the guide rail are rectangular in structure.

[0009] Furthermore, the bottom of the slide is open so that the guide rail can extend to the outside of the slide.

[0010] Furthermore, the above solution includes an open top and front surface of the fixing frame to form a shell that can enclose the jack.

[0011] Furthermore, the above solution includes a docking seat on the inner surface of the top of the movable frame for connection with the end of the jack rod.

[0012] Furthermore, the above solution includes viewing windows on both sides of the base.

[0013] Furthermore, the above solution includes fastening screw holes on both sides of the base to secure the base by adding bolts.

[0014] Furthermore, the top block of the above scheme has a triangular structure, and the top is composed of a central arc surface and two inclined surfaces on both sides.

[0015] Furthermore, the angle between the two inclined planes is consistent with the angle between the end wall panel and the crossbar of the railway freight car.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] Compared to traditional operating methods, this tooling can quickly and accurately increase the working space, significantly reduce the time required to remove the limit stop, greatly improve work efficiency, and reduce labor and time costs. Through the cooperation of the base with the coupler shoulder, the top block with the end wall plate, and the cross strap, a stable support structure is formed. The hinged design effectively transforms the lifting force of the jack into downward pressure on the coupler body, successfully widening the narrow space between the coupler body and the buffer, allowing operators to easily access the limit stop and greatly improving operational convenience. Furthermore, the stable support and reasonable force transmission mechanism avoid the risk of vehicle component damage due to insufficient operating space, while reducing safety hazards caused by improper operator posture or inconvenient tool use, effectively ensuring operational safety and reducing the accident rate.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0024] See attached document Figure 1 -Appendix Figure 4 As shown, a tooling for removing a limit baffle of a railway freight car includes a jack 1, a fixed frame 2, a movable frame 3, a connecting rib seat 4, a base 5, and a top block 6. The bottom of the jack 1 is mounted on the fixed frame 2, and the top of the jack 1 is connected to the movable frame 3, which is slidably mounted on the fixed frame 2, so that the movable frame 3 can rise or fall along the fixed frame 2 as the jack 1 operates. In addition, a connecting rib seat 4 is installed at the end of both the fixed frame 2 and the movable frame 3. The connecting rib seat 4 on the fixed frame 2 is hinged to the base 5, which is used to lock onto the hook shoulder of the railway freight car coupler, and the connecting rib seat 4 on the movable frame 3 is hinged to the top block 6, which is used to abut against the connection between the end wall panel and the crossbar of the railway freight car.

[0025] In use, the tooling is secured to the coupler shoulder via the base 5, and the top block 6 rests against the connection between the railway freight car end wall and the crossbar, forming a stable support structure. After the jack 1 is activated, the lifting force of the jack 1 is transmitted to the movable frame 3, which rises along the fixed frame 2. Since the movable frame 3 is hinged to the top block 6 and the fixed frame 2 is hinged to the base 5, this hinged structure allows the lifting force of the jack 1 to be converted into a gradually downward pressure on the coupler body. Under the action of the downward pressure, the coupler body overcomes the original positional limitations and moves downward, thereby gradually increasing the distance between the coupler body and the coupler buffer, widening the originally narrow working space, and creating conditions for removing the limit baffle.

[0026] Specifically, refer to the appendix Figure 2 As shown, the fixed frame 2 has two slides 21 formed on its inner side, and the movable frame 3 is provided with guide rails 31 that cooperate with the two slides 21. Through the sliding cooperation design of the two, the tooling is designed as a split structure, which is convenient for on-site use and carrying. Moreover, both the slides 21 and the guide rails 31 are rectangular structures. The rectangular guide rails 31 and the slides 21 are easy to cooperate during use, and at the same time, the safety hazard of the tooling rotating due to the torque generated during use is eliminated. Furthermore, the bottom of the slides 21 is open so that the bottom of the guide rails 31 can extend to the outside of the slides 21.

[0027] Among them, refer to the appendix Figure 1As shown, the top and front of the fixed frame 2 are open to form a shell that can enclose the jack 1. In use, the jack 1 is installed inside the shell, and the lifting force it generates is vertically transmitted to the movable frame 3 through the fixed frame 2. The movable frame 3 rises stably along the shell's guide structure, and then the force is converted into a downward pressing force on the coupler body through the connecting rib seat 4. The open design does not affect the installation, disassembly, or observation of the working status of the jack 1, and it also uses the side of the shell to constrain its lateral displacement, ensuring that the force is accurately transmitted in the vertical direction. This avoids force transmission deviations caused by the tilting or shaking of the jack 1, thereby stabilizing the downward pressing of the coupler, widening the working space between the coupler body and the buffer, and creating conditions for the smooth removal of the limit baffle.

[0028] Additionally, please refer to the appendix. Figure 2 As shown, the inner surface of the top of the movable frame 3 is provided with a docking seat 32 to connect with the top rod end of the jack 1, forming a tight force transmission interface. This point-to-point force transmission method avoids the deviation or loss of the lifting force during the transmission process, ensuring that the thrust of the jack 1 can be efficiently and stably converted into the power to move the movable frame 3.

[0029] In the above scheme, refer to the appendix Figure 2 As shown, viewing windows 51 are provided on both sides of the base 5. These windows allow users to check whether the base 5 and the coupler shoulder are fully fitted during use, thus achieving weight reduction. Due to tolerances in the manufacturing process of the coupler shoulder, the base 5 is designed with an interference fit. To ensure the stability of the base 5 during use, please refer to the attached diagram. Figure 2 As shown, fastening screw holes 52 are also provided on both sides of the base 5, and the base 5 can be fastened by adding bolts to ensure stability.

[0030] In addition, to ensure a perfect fit between the tooling and the vehicle body and to eliminate the safety hazard of existing tooling top movement, the following measures are taken, with reference to the attached... Figure 1 As shown, the top block 6 has a triangular structure, and the top is composed of a central arc surface 61 and two inclined surfaces 62 on both sides. The included angle between the two inclined surfaces 62 is consistent with the included angle of the railway freight car end wall panel and the cross strip.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
