During the operation process, due to the occurrence of situations such as box body deformation, corner fitting deformation, and flat car deformation, the container may be stuck due to being out of the box, which has a very large impact on the unloading operation. Once forced lifting is carried out, it is extremely easy to cause a safety accident of the flat car deck being lifted and the vehicle derailing. At the same time, it has a great impact on the operation efficiency and personal safety. The methods commonly used in this situation are: one is to use other mechanical aids such as forklifts and reach stackers to assist the gantry crane in unloading the vehicle. The cross-operation of various mechanical devices is extremely easy to cause safety accidents, and vehicle collisions are also likely to cause damage to the box body; the other is to use gas welding cutting to cut the box corners and then unload the vehicle, which has great potential hazards in terms of fire safety and box body safety.

[0003] Due to the upward blocking surface of the F-TR lock being stuck with the corner fitting, the corner fitting cannot be separated from the lock head, making the container easy to be stuck during lifting. Therefore, there is an urgent need for an emergency unlocking tool for the F-TR lock of a railway container to solve the above problems. Content of the Utility Model

[0023] To make the above objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific implementation manners of the present utility model is provided in conjunction with the accompanying drawings of the specification.

[0024] Embodiment 1

[0025] Referring to Figures 1-3 , as the first embodiment of the present utility model, an emergency unlocking tool for the F-TR lock of railway containers is provided. This emergency unlocking tool for the F-TR lock of railway containers includes an external hexagonal wrench 1 and a hexagonal nut 2 that is snap-fitted with it. A threaded rod 3 is in threaded cooperation with the hexagonal nut 2. One end of the threaded rod 3 is sleeved with a support seat 4, and the other end is fixedly connected with a positioning block 5. The support seat 4 is rotatably connected with the hexagonal nut 2, and the positioning block 5 is snap-fitted with the container corner fitting.

[0026] In the above technical solution, one end of the positioning block 5 can pass through the through hole of the corner fitting, and then rotate to make the positioning block 5 snap-fitted with the corner fitting. One end of the support seat 4 can be abutted against the side plate on the flat car. After the external hexagonal wrench 1 is snap-fitted with the hexagonal nut 2, by driving the external hexagonal wrench 1 to drive the hexagonal nut 2 to rotate, due to the positioning block 5 abutting against the corner fitting and the support seat 4 abutting against the side plate, the threaded rod 3 can be limited, so that the threaded rod 3 can slide straight outward in the support seat 4 and drive the positioning block 5 to displace synchronously, so that the positioning block 5 exerts a lateral thrust on the corner fitting.

[0027] The positioning block 5 includes a first positioning plate 501. One side of the first positioning plate 501 is fixedly connected to the threaded rod 3, and the other side is fixedly connected with a connecting column 502. One end of the connecting column 502 is fixedly connected with a second positioning plate 503.

[0028] In the above technical solution, the size of the first positioning plate 501 is larger than the size of the through hole of the angle member, the size of the second positioning plate 503 is smaller than the size of the through hole of the angle member, and the diameter of the connecting column 502 is smaller than the width of the through hole of the angle member. The axial length of the connecting column 502 is slightly larger than the thickness of the through hole of the angle member. After the second positioning plate 503 penetrates into the angle member, the first positioning plate 501 is arranged outside the angle member. When the threaded rod 3 moves horizontally, it drives the positioning block 5 to exert a lateral thrust on the angle member.

[0029] Among them, the positioning block 5 is made by cutting and welding steel plate materials, with simple process, stable structure, convenient material selection and easy production.

[0030] The support seat 4 includes a bottom plate 401, and a cylinder seat 402 is fixedly connected to the bottom plate 401. One end of the threaded rod 3 is arranged inside the cylinder seat 402.

[0031] In the above technical solution, the cylinder seat 402 limits the movement of the threaded rod 3. At the same time, one side of the bottom plate 401 abuts against the side plate of the flat car, so that the threaded rod 3 can drive the positioning block 5 to move horizontally.

[0032] In the actual use process, an anti-slip pad can be set on the surface of the bottom plate 401 that contacts the side plate of the flat car, so as to increase the friction between the bottom plate 401 and the side of the flat car and prevent the support seat 4 from slipping when the hexagonal nut 2 rotates.

[0033] The outer diameter of the threaded rod 3 is smaller than the inner diameter of the cylinder seat 402, and the axial length of the threaded rod 3 is greater than the axial length of the cylinder seat 402.

[0034] In the above technical solution, the cylinder seat 402 limits the threaded rod 3, and the axis of the threaded rod 3 coincides with the axis of the cylinder seat 402, so that the threaded rod 3 moves straight inside the cylinder seat 402.

[0035] A plurality of rib plates 404 are welded between the cylinder seat 402 and the bottom plate 401.

[0036] In the above technical solution, through the arrangement of a plurality of rib plates 404, the structural stability between the bottom plate 401 and the cylinder seat 402 can be increased, and the amplitude of deformable force can be improved.

[0037] One end of the threaded rod 3 is fixedly connected with a limiting rod 301, and the limiting rod 301 is arranged inside the cylinder seat 402.

[0038] In the above technical solution, refer to Figure 3, there are two cylindrical cavities with different sizes, upper and lower, inside the cylinder base 402. The diameter of the upper cavity is smaller than that of the lower cavity. The outer wall of the threaded rod 3 is in sliding contact with the inner wall of the upper cavity, and the limit rod 301 is arranged in the radial direction of the threaded rod 3. The length of the limit rod 301 is smaller than the diameter of the lower cavity and larger than the diameter of the upper cavity, so that the limit rod 301 can limit the sliding of the threaded rod 3 in the cylinder base 402 and prevent the threaded rod 3 from detaching from the cylinder base 402.

[0039] During use, insert the second positioning plate 503 into the corner fitting, so that the connecting column 502 is arranged in the through hole of the corner fitting. Then rotate the device by 90°. Make the first positioning plate 501 and the second positioning plate 503 closely abut against the corner fitting. At the same time, make the bottom plate 401 closely abut against the side plate of the flatbed truck. After clamping the external hexagonal wrench 1 with the hexagonal nut 2, drive the hexagonal nut 2 to rotate by rotating the external hexagonal wrench 1. Since the threaded rod 3 is jointly limited by the positioning block 5 and the corner fitting, and the bottom plate 401 and the side plate, the threaded rod 3 can move straight under the rotational driving force of the hexagonal nut 2, and drive the positioning block 5 to abut against the corner fitting, so as to apply a lateral thrust to the corner fitting, which helps to create a gap between the corner fitting and the stuck surface of the lock head, facilitating the container to disengage from the lock head.

[0040] Embodiment 2

[0041] Refer to Figure 2 , which is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that arc chamfers 504 are provided at the corners of the first positioning plate 501 and the second positioning plate 503, and the length of the first positioning plate 501 is greater than the length of the second positioning plate 503.

[0042] In the above technical solution, the provision of the arc chamfer 504 can prevent scratching the hands of personnel during use. The shape of the second positioning plate 503 is the same as the shape of the through hole of the corner fitting, and the size of the second positioning plate 503 is the same as the size of the through hole of the corner fitting, so that the second positioning plate 503 can be quickly inserted into the corner fitting, enabling the first positioning plate 501 to abut against the outside of the corner fitting.

[0043] The remaining structure is the same as that of Embodiment 1.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not restrictive. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present utility model, and they should all be covered within the scope of the claims of the present utility model.
