Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] Example
[0020] like Figure 1-Figure 2 As shown, the utility model provides a special tool for disassembling the leg pins of a slag ladle car.
[0021] It includes an impact sleeve 1 and a connecting pin rod 2, a plug-in mechanism is arranged between the impact sleeve 1 and the connecting pin rod 2, the plug-in mechanism includes a plug-in rod 3 and a connecting rod 4, the plug-in rod 3 is arranged at the output end of the impact sleeve 1, the connecting rod 4 is arranged at one end of the connecting pin rod 2, a square groove 5 is arranged inside the end of the plug-in rod 3 facing the connecting pin rod 2, the connecting rod 4 is plugged into the inside of the square groove 5, a cavity 6 is provided inside the end of the connecting rod 4 facing the plug-in rod 3, two symmetrically arranged L-shaped limit blocks 7 are arranged in the cavity 6, the vertical part of the limit block 7 passes through the side wall of the connecting rod 4 and extends to the outside of the connecting rod 4, a spring 8 is arranged between the two groups of the limit blocks 7, the upper and lower side walls of the plug-in rod 3 are provided with positioning holes, the positioning holes are connected with the square groove 5, the impact sleeve 1 and the connecting pin rod 2 are spliced through the plug-in rod 3 and the connecting rod 4,
[0022] An impact hammer is arranged inside the impact sleeve 1, one end of the impact hammer is connected to the input end of the impact sleeve 1, and the other end is opposite to one end of the plug rod 3. The impact hammer is used to apply an impact force to one end of the plug rod 3 through the air pressure or hydraulic pressure introduced from the input end of the impact sleeve 1, thereby driving the connecting pin rod 2 to impact, so as to facilitate the removal of the pin on the connecting pin rod 2;
[0023] During use of the utility model, the tool of the application is installed on the input end of the impact sleeve 1, the output end of the impact sleeve 1 is connected to one end of the plug-in rod 3, the other end of the plug-in rod 3 is plugged into one end of the connecting rod 4, and the other end of the connecting rod 4 is connected to one end of the connecting pin rod 2 to form a whole.
[0024] Align the other end of the connecting pin rod 2 with the pin that needs to be removed, and pass the pin through the hole of the connecting pin rod 2 so that the connecting pin rod 2 fits tightly with the pin.
[0025] Air pressure or hydraulic pressure is introduced through the input end of the impact sleeve 1 to drive the impact hammer to exert an impact force on one end of the plug-in rod 3, thereby driving the connecting pin rod 2 to impact, so that the pin is gradually loosened and removed from the support leg.
[0026] When the pin is completely disassembled, the tool of the present application is pulled out from the pin, the pin and the tool are separated, and the disassembly work is completed.
