Description

Technical Field

[0001] The present application relates to the technical field of door closing tools for open wagons, and in particular to a door closing tool for a lower side door of an open wagon compartment. Background Art

[0002] An open car is a railway freight vehicle with end walls but no roof. It is mainly used to transport coal, ore, building materials, steel, etc. It is widely used in industrial and mining enterprises. Each open car has a middle side door and two lower side doors. The doors need to be closed and tied for reinforcement after unloading and loading.

[0003] For the lower side door, the lower side door hinge needs to be pressed against the side wall of the carriage so that the lower side door buckle can be rotated downward into the buckle seat to lock the hinge. However, because the door is opened and closed violently or squeezed by the cargo, the lower side door door belt, hinge or round pin is deformed, making it difficult to insert the buckle into the lower side door buckle seat. In the past, multiple operators cooperated to use a flame-heated sledgehammer to correct the hinge and make it close to the side wall. In serious cases, the cargo needed to be unloaded and returned to the repair workshop to replace the lower side door round pin before production could be put into operation, which increased labor intensity and prolonged production time. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide a door closing tool for the lower side door of an open car compartment, which can solve the technical problems raised by the background technology.

[0005] An embodiment of the present application provides a tool for closing the lower side door of an open car compartment, comprising a hook, a connecting rod, a connecting assembly and a force rod, wherein the hook is connected to one end of the connecting rod, and the other end of the connecting rod is rotatably connected to the force rod through the connecting assembly, and the length of the hook after connection with the connecting rod is greater than or equal to the distance between the upper end of the force rod and the connecting assembly, and the upper end of the force rod is provided with a locking groove.

[0006] Furthermore, the connecting assembly includes a fixed clamp and a rotating shaft, the fixed clamp is close to the upper end of the force rod and is fixedly arranged on the force rod, the rotating shaft is rotatably arranged on the fixed clamp, and one end of the connecting rod away from the hook is fixedly connected to the rotating shaft.

[0007] Furthermore, the hook is U-shaped.

[0008] Furthermore, the hook and the connecting rod are integrally formed.

[0009] Furthermore, the fixing clamp is provided with a groove, the rotating shaft passes through the groove, and one end of the connecting rod away from the hook is located in the groove and fixedly connected to the surface of the rotating shaft.

[0010] Beneficial effects of the utility model:

[0011] The utility model utilizes the lever principle and can easily apply several times the force to the object through the reasonable distribution of the hook and the force-adding rod, and easily completes the closing of the deformed lower side door, avoiding the waste of resources caused by replacing parts and unloading the vehicle due to the inability to close the door, thereby shortening the loading time and avoiding safety risks.

[0023] like Figure 1 As shown, the present application provides a door closing tool for the lower side door of an open car compartment, including a hook 1, a connecting rod 2, a connecting assembly and a force rod 5. The hook 1 is connected to one end of the connecting rod 2, and the other end of the connecting rod 2 is rotatably connected to the force rod 5 through the connecting assembly. The length of the hook 1 after being connected to the connecting rod 2 is greater than or equal to the distance between the upper end of the force rod 5 and the connecting assembly. The upper end of the force rod 5 is provided with a locking groove 6. When in use, the lower side door hinge is closed and lifted up until the hanging ring is separated from the lower side door hook column on the upper side beam, the lower side door hinge is as close to the side wall as possible, the force rod 5 is parallel to the side wall, and the hook 1 is hooked vertically Hold the inner steel plate of the lower side beam, rotate the force rod 5 and use its top locking groove 6 to support the end of the hinge. The operator works upward on the tail end of the force rod 5, uses the lever principle to press the hinge against the side wall, and rotates the lower side door buckle downward into the buckle seat until the hinge is completely locked. The structure is simple and practical. It uses the lever principle and the reasonable distribution of the hook 1 and the force rod 5 to easily apply several times the power to the object, and easily completes the closing of the deformed lower side door, avoiding the waste of resources caused by replacing accessories and unloading the car due to the inability to close the car door, which shortens the loading time and avoids safety risks.

[0024] like Figure 1 The connecting assembly shown includes a fixed card 3 and a rotating shaft 4. The fixed card 3 is close to the upper end of the force rod 5 and is fixed on the force rod 5. The rotating shaft 4 is rotatably set on the fixed card 3. The end of the connecting rod 2 away from the hook 1 is fixedly connected to the rotating shaft 4. The connecting assembly is used to realize that the connecting rod 2 can rotate relative to the force rod 5, so that the hook 1 on the connecting rod 2 hooks the inner steel plate of the lower side beam, and can apply rotational force to the force rod 5.

[0025] like Figure 1 The hook 1 shown is U-shaped, which is convenient for hooking the inner steel plate of the lower side beam.

[0026] like Figure 1 The hook 1 and the connecting rod 2 are formed in one piece, making the structure more stable.

[0027] like Figure 1 The fixing clamp 3 shown is provided with a groove, and the rotating shaft 4 passes through the groove. The end of the connecting rod 2 away from the hook 1 is located in the groove and is fixedly connected to the surface of the rotating shaft 4. Specifically, the end of the connecting rod 2 away from the hook 1 is welded to the surface of the rotating shaft 4, and the end of the connecting rod 2 away from the hook 1 is located in the groove, and combined with the rotating shaft 4, it can prevent slipping.

[0028] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
