AI Technical Summary
After the side door in the open car is violently switched, the door lock device is easily deformed, making it impossible to easily insert the lock head into the upper side beam lock hole, resulting in inconvenient closing and dangerous operation.
A closed door tool including a booster rod, a pressure support arm and a hook fastener was designed. The lever principle provides double power through the reasonable distribution of the booster rod, a pressure support arm and a hook fastener, and easily completes the closing of the side door in the deformation.
The deformed mid-side door is easily closed, avoiding the risk of high-altitude operators needing to climb up the side beams and shortening the loading time.

Abstract
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 side door in 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 middle side door, it is necessary to rotate and lift the locking lever upward to the lock head, insert it into the lock pin hole of the upper side beam, and completely insert the handle into the stopper iron to complete the locking. However, since the door can be opened and closed violently, the door lock device will be deformed, making it difficult to easily insert the lock head into the lock hole of the upper side beam. In the past, the operator climbed up the side wall and used a crowbar to squeeze the upper end of the middle side door close to the upper side beam. It was inconvenient to use force and the operator needed to ride on the upper side beam, which was extremely unsafe. Summary of the invention
[0004] The purpose of the embodiments of the present application is to provide a tool for closing the side door in an open car compartment, which can solve the technical problems raised by the background technology.
[0005] An embodiment of the present application provides a side door closing tool for an open car compartment, comprising a power-assisting rod, a pressure support arm and a hook fastener, one end of the power-assisting rod is fixedly connected to the hook fastener, one end of the pressure support arm is fixedly connected to the power-assisting rod, the pressure support arm is located below the opening of the hook fastener, and the opening width of the hook fastener is adapted to the width of the upper side beam of the open car.
[0006] Furthermore, there is an angle between the power-assisting rod and the hook fastener, and the angle is 150° to 170°.
[0007] Furthermore, a silicone pad is provided at one end of the pressure support arm away from the booster rod.
[0008] Furthermore, an anti-slip sleeve is provided at one end of the power assist rod away from the hook fastener.
[0009] Furthermore, the distance between the top of the pressure support arm and the bottom of the hook fastener is 200 to 300 mm.
[0010] Furthermore, the power assist rod is a telescopic rod, and the hook fastener and the pressure support arm are fixedly arranged at the telescopic end.
[0011] Beneficial effects of the utility model:
[0012] The utility model utilizes the lever principle and can easily apply double power to the object through the reasonable distribution of the power lever, the pressure support arm and the hook fastener, and easily completes the closing of the side door during deformation, eliminating the risk of falling from a high altitude caused by the previous need for operators to climb onto the side beams for operation, and also shortens the loading time.

[0024] like Figure 1 As shown, the present application provides a door closing tool for the middle side door of an open car compartment, comprising a power-assisting rod 1, a pressure support arm 2 and a hook fastener 3. One end of the power-assisting rod 1 is fixedly connected to the hook fastener 3. Specifically, the hook fastener 3 is welded to one end of the power-assisting rod 1, and one end of the pressure support arm 2 is fixedly connected to the power-assisting rod 1. Specifically, one end of the pressure support arm 2 is welded to the power-assisting rod 1. The pressure support arm 2 is located below the opening of the hook fastener 3. The opening width of the hook fastener 3 matches the width of the upper side beam of the open car. When in use, the left door of the open car is closed first, and then the right door is closed. The entire door closing tool is hung on the inner side of the upper side beam of the open car by using the hook fastener 3, so that the opening of the hook fastener 3 is perfectly combined with the upper side beam, the pressure support arm 2 is aligned with the middle position of the middle side door lock box, and the power-assisting rod 1 is applied to the middle side door. The upper end of the middle side door is squeezed by the pressure support arm 2 to be close to the upper side beam, and the lock head is inserted into the lock hole of the upper side beam to easily close the door.
[0025] like Figure 1As shown, there is an angle 4 between the power rod 1 and the hook fastener 3, and the angle 4 is 150° to 170°. Preferably, the angle 4 between the power rod 1 and the hook fastener 3 is 160°, so that the user can better apply force to the power rod 1.
[0026] like Figure 1 As shown, a silicone pad 5 is provided at one end of the pressure arm 2 away from the booster rod 1, and the pressure arm 2 contacts the middle position of the middle door lock box through the silicone pad 5, which can prevent marks from being left in the middle position of the middle door lock box when squeezed.
[0027] like Figure 1 As shown, an anti-skid cover 6 is provided at one end of the power-assisting rod 1 away from the hook fastener 3, so as to prevent the user from slipping when picking up the power-assisting rod 1.
[0028] like Figure 1 As shown, the distance between the top of the pressure arm 2 and the bottom of the hook 3 is 200-300 mm. In this embodiment, the distance between the top of the pressure arm 2 and the bottom of the hook 3 is 250 mm to prevent the pressure arm 2 from hindering the hook 3 from hooking the upper side beam of the open car.
[0029] like Figure 1 As shown, the power-assisting rod 1 is a telescopic rod, and the hook fastener 3 and the pressure support arm 2 are fixedly arranged at the telescopic end, so that the user can adjust the length of the power-assisting rod 1 according to actual needs, which is suitable for the user to operate and apply force.
[0030] 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.
