[0002] The coal required by the power plant generator set is transported by railway gondola cars, and after being unloaded by the dumper system, it is stored in the coal yard or fed into the silo. Each carriage of the gondola car has multiple side doors, each side door being 1300 mm wide, 1000 mm high, and 6 mm thick; a train of gondola cars full of coal is divided into groups of two and unloaded by the dumper. After that, the subsequent empty carriages are formed into a train and pushed out of the factory. Since the dumper cannot completely dump all the coal in the carriage, special personnel need to enter the carriage to clean it on the empty car line; the cleaning personnel enter the car through the side door on the carriage, and use shovels and brooms to remove all the remaining coal, ensuring that the carriages pushed out of the factory are clean and free of debris.

[0003] Before the cleaning personnel finish their work and withdraw from the carriage, the side doors of the carriage are in an open state. Therefore, a special tool must be used to keep the side doors open; the current fixing tool uses a special iron hook, and an iron ring is fixed on the upper part of the carriage. Among them, the total length of the iron hook is about 1.85 m, the diameter is 12 mm, and both ends are bent to hook the iron ring on the upper part of the carriage and the lower edge of the side door respectively, so as to keep the side door open; the opening angle of the side door after opening is about 60°, and the bottom opening distance is about 0.9 m, which is enough for adult men to enter and exit; when the cleaning work is over and the cleaning personnel withdraw from the carriage, the iron hook is removed and the side door is closed.

[0004] When using the iron hook to hook the lower edge of the side door, when the staff enter and exit, they may accidentally hit the iron hook, and the iron hook may become unhooked, affecting the safety of the staff. At the same time, the opening angle of the side door cannot be adjusted when the side door is open, and the applicability is lacking; in addition, when using the iron hook for fixing, when closing the side door, there may be a situation where the iron hook is forgotten to be removed. The iron hook carried out of the factory is hanging on the carriage, posing a safety hazard to railway transportation safety. Summary of the Utility Model

For example, a process, method, system, product or device comprising a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices; "fixed" or "fixed connection" generally refers to common mechanical connection methods, such as threaded connection, welding or bonding, etc.

[0031] In the prior art, before the cleaning personnel finish their work and withdraw from the carriage, the side door of the carriage is always in an open state. Therefore, a special tool must be used to keep the side door open; as Figure 1 shown, the current fixing tool uses a special iron hook 300. An iron ring is fixed on the upper part of the carriage. Among them, the total length of the iron hook 300 is about 1.85 m, the diameter is 12 mm, and both ends are bent to respectively hook the iron ring on the upper part of the carriage and the lower edge of the side door, so as to keep the side door open; the opening angle of the side door after opening is about 60°, and the bottom opening distance is about 0.9 m, which is sufficient for an adult male to enter and exit; when the cleaning work is over and the cleaning personnel withdraw from the carriage, the iron hook 300 is taken down and the side door is closed.

[0032] The existing iron hook 300 has the following problems when fixing the side door:

[0033] When using the existing fixing device, that is, the iron hook 300 hooks the lower edge of the side door, when the staff enters and exits, they will accidentally hit the iron hook 300, which will not only cause scratches on the palm, but also the iron hook 300 is prone to unhook, resulting in the side door accidentally closing and pinching the staff, there are safety hazards, and it is inconvenient to install multiple iron rings on the carriage body 100; at the same time, the opening angle of the side door cannot be adjusted when the side door is open, and the applicability is lacking; in addition, when using the iron hook 300 for fixing, when closing the side door, the side door can still be closed without removing the iron hook 300, so there will be a situation where the staff forgets to remove the iron hook 300 from the carriage, and the hanging iron hook 300 on the carriage poses a safety hazard to railway transportation safety.

[0034] In addition, since both ends of the iron hook 300 need to be bent, the two ends are prone to breakage, resulting in the side door accidentally closing, and the safety is poor. Moreover, the iron hook 300 needs to be inserted into the iron ring at the upper end, and the operation is inconvenient.

[0035] The present utility model provides a fixing device for the lower side door of an open railway wagon, as Figure 2 andFigure 3 As shown, in this embodiment, the fixing device for the lower side door of the railway gondola car is used for the side door 400 of the gondola car body 100. Specifically, it is used to fix the side door 400 of the gondola car to prevent the side door 400 from closing when the side door 400 of the gondola car is opened. The fixing device includes a handle 10 and a limiting part 20. In this embodiment, the limiting part 20 is arranged as a stop structure; the handle 10 is connected to the limiting part 20; when the side door 400 of the gondola car is opened, the limiting part 20 can be inserted between the upper end of the side door 400 of the gondola car and the gondola car body 100 to limit the closing of the side door 400 of the gondola car, and the handle 10 is for the staff to pick up and use.

[0036] In order to understand the limiting part 20 in more detail, the limiting part 20 is set to have an insertion end 21 that can be inserted between the side door 400 of the gondola car and the gondola car body 100 and a connection end 22 connected to the handle 10. The insertion end 21 is inserted between the side door 400 of the gondola car and the gondola car body 100 to limit the closing of the side door 400 of the gondola car; in order to be able to adjust the opening angle of the side door 400 of the gondola car, the thickness of the limiting part 20 gradually increases from the insertion end 21 to the connection end 22 direction. Therefore, when the limiting part 20 is inserted between the side door 400 of the gondola car and the gondola car body 100, the insertion depth of the limiting part 20 can be adjusted to adjust the opening angle of the side door 400 of the gondola car.

[0037] The using method of the fixing device of the present utility model: When it is necessary to open the extra-long side door of the gondola car, the cleaning staff holds the handle 10 of the fixing device with the left hand and pulls up the lower part of the side door with the right hand. When the door is opened to a certain angle, insert the insertion end 21 of the limiting part 20 of the fixing device into the gap of the side door 400 of the gondola car from the upper end of the side door 400 of the gondola car to keep the side door 400 of the gondola car in an open state; if it is necessary to adjust the opening angle, the side door 400 of the gondola car can be further pulled, and the limiting part 20 will continue to be inserted into the gap by gravity or manually. Adjust the insertion depth of the limiting part 20, and then release the side door 400 of the gondola car. Finally, rely on the limiting part 20 to firmly fix the side door 400 of the gondola car to keep the side door 400 of the gondola car in an open state; when it is necessary to close the side door 400 of the gondola car, just pull up the lower part of the side door 400 of the gondola car again, and at the same time hold the handle 10 of the fixing device to pull out the limiting part 20. After releasing the hand, the side door 400 of the gondola car will close.

[0038] Through the setting of the fixing device of the present utility model, compared with the prior art, it is not necessary to install iron rings on the gondola car body 100 to realize the opening and fixing of the side door 400 of the gondola car. The installation is convenient, and there will be no phenomenon that the side door closes due to accidental touch during opening, improving safety; during use, only the staff needs to hold the handle 10 and insert the limiting part 20 into the upper end gap of the side door 400 of the gondola car, which is convenient to use, and the opening angle of the side door 400 of the gondola car can be adjusted according to the insertion depth, with strong applicability and convenient adjustment.

[0039] The fixing device of the utility model has a simple structure and is only composed of a handle 10 and a limiting part 20. The overall length of the fixing device is 1m and the weight is 1.5kg, which is convenient for the staff to operate. Among them, the length of the handle 10 is set to 900mm.

[0040] In order to improve the overall safety and stability of the fixing device; the limiting part 20 is set in the shape of a triangular stopper, and the cross-section of the limiting part 20 is set in the structure of a right triangle. In other embodiments, it can be adjusted according to the specific shape, for example, set in the structure of a trapezoid; among them, for the limiting part 20 with a right triangle structure, the lengths of the two right sides are 200mm and 90mm respectively, and the width of the limiting part 20 is 65mm; the end face of the long right side of the limiting part 20 is in close contact with the outside of the carriage body 100 to ensure the stability of the force on the limiting part 20 and avoid the fracture of the limiting part 20.

[0041] In order to prevent the limiting part 20 from being squeezed and deformed by the side door 400 of the open wagon, the material of the limiting part 20 is set to high-strength polyurethane, that is, cow tendon, which has high strength and strong toughness, can greatly avoid the deformation of the limiting part 20, and is light in weight, which is convenient for the staff to hold and use; the handle 10 is made of high-strength nylon material, which has high strength and is light in weight and is suitable for use.

[0042] In order to enable the staff to conveniently insert the limiting part 20 into the gap at the upper end of the side door 400 of the open wagon with one hand, the connection angle between the handle 10 and the limiting part 20 is set to 80°. In this embodiment, the handle 10 is connected to the long right side of the triangular limiting part 20 at an angle of 80°.

[0043] In order to prevent the limiting part 20 from separating from the handle 10 and improve the connection strength and connection convenience between the limiting part 20 and the handle 10; a connection hole is opened on the limiting part 20, and one end of the handle 10 passes through the connection hole and is threadedly connected to the limiting part 20; specifically, internal threads are provided in the connection hole, external threads are provided on the handle, and one end of the handle is inserted into the connection hole of the limiting part and tightened. At the same time, the part of the handle 10 inserted into the connection hole is bonded to the limiting part 20. In this embodiment, the two are bonded and fixed by hot melt adhesive, and the connection strength between the handle and the limiting part is improved through the two settings of threaded connection and bonding.

[0044] In order to further improve the installability, strengthen the strength of the limiting part 20 and avoid the phenomenon of the limiting part 20 breaking; as Figure 4 shown, a reinforcing block 30 is arranged inside the limiting part 20. The reinforcing block 30 can be set in a structure with the same material as the side door 400 of the open wagon. High-strength polyurethane is wrapped outside the reinforcing block 30. When the external polyurethane breaks, the reinforcing block 30 can resist the side door 400 of the open wagon and prevent the side door 400 of the open wagon from closing; one end of the handle 10 is inserted into the inside of the limiting part 20 and connected to the reinforcing block 30, which further avoids the separation of the limiting part 20 from the handle 10.

[0045] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
