[0018] The utility model is further described with reference to the accompanying drawings.

[0019] As shown in the figure, a railway freight car door hasp cutting tool includes an electric hydraulic pump 1, a hydraulic jack 2 and a fixture 3. The output end of the electric hydraulic pump 1 is connected to the input end of the hydraulic jack 2. The fixture 3 includes a hook with a C-shaped cross-section. A lifting ring 4 is provided at the top of the hook and a supporting base is provided at the bottom. The hydraulic jack 2 is located on the supporting base, the door axle pin is located in the fixture, and the hydraulic jack 2 is located at the bottom of the freight car provided with the door axle pin.

[0020] The inner side of the upper end of the clamp 3 is a 45° inclined surface inclined upward.

[0021] The support base includes two support columns 5 located at the bottom of the fixture 3 , and a base 6 is provided at the bottom of the support columns 5 .

[0022] A clamping plate 7 with an arc-shaped cross section is disposed at one end of the base 6 close to the support column 5 , and the arc of the clamping plate 7 matches the outer diameter of the hydraulic jack 2 .

[0023] The support column 5 is provided with a fixing card for fixing the hydraulic jack 2, and the fixing card includes an arc-shaped card 8 matching the outer diameter of the hydraulic jack 2 and a sleeve 1 9 and a sleeve 2 10 respectively located on the support column 5. One end of the arc-shaped card 8 is provided with a sleeve 3 12 corresponding to the sleeve 1 9, and the other end is provided with a sleeve 4 16 corresponding to the sleeve 2 10. The sleeve 1 9 and the sleeve 3 12 are rotatably connected by a pin shaft 11, and a pin shaft 2 13 is inserted into the sleeve 2 10 and the sleeve 4 16.

[0024] The cutting tool further comprises a sling 14, one end of which is connected to the sling ring 4 at the top of the fixture 3 through an S-shaped hook 15, and the other end of which is hung on the truck door.

[0025] The electric hydraulic pump 1 utilizes the plug in the electric hydraulic pump 1 to reciprocate and transmits the generated power to the hydraulic jack 2 through the hydraulic oil pipe. The hydraulic jack 2 cuts off the deformed door buckle seat by combining the shear force and the hydraulic pressure to form a strong combined force.

[0026] The S-shaped hook 15 is inserted into the lifting ring 4, and the clamp is hung on the door axis pin to prevent the utility model from falling.

[0027] The method of using the utility model is as follows:

[0028] Step 1. After the technical inspection finds that the door hasp seat is deformed, ineffective, or damaged, the train inspection personnel will replace the door hasp seat on site and first lift the lower door;

[0029] Step 2. The end 3 of the fixture is hung on the door shaft pin seat, the S-shaped hook 15 is hung in the lifting ring 4, and the cut door buckle seat fixture is lifted;

[0030] Step 3. Place the hydraulic jack on the support base and insert the positioning pin;

[0031] Step 4. After fixing, use the oil pipe to connect the electric hydraulic pump 1 and the hydraulic jack 2;

[0032] Step 5. The train inspection personnel operate the manual switch of the electric hydraulic pump 1 to pressurize the hydraulic jack 2. When a certain shear force is reached, the door buckle seat can fall off. At this time, the deformed, invalid, and damaged door buckle seat can be replaced.

[0033] In the past, door latch seat processing methods were centralized repair or use of angle grinders. With the development of this tool, door latch seat deformation failures can be handled in the train fleet, reducing the links of shunting and train detention. At the same time, the tool material is made of scrap steel, achieving the purpose of reducing costs and increasing efficiency.

[0034] In the past, angle grinders were usually used to cut door buckle seat deformation problems in train fleets. However, due to battery life issues, they could not operate continuously and the cutting speed was slow, resulting in low efficiency. The development of this tool effectively solved this problem.

[0035] It reduces the potential safety hazards caused by the use of angle grinders in the past, reduces the occurrence of technical inspection time overtime caused by handling door buckle seat deformation failures in train teams, improves train turnover rate, and ensures safe and punctual operation of trains. At the same time, this special repair tool is suitable for various working environments and sites, and is suitable for large-scale promotion and use.
