Detailed Description
Examples
A special tool for disassembling a pin shaft of an underground scraper consists of a screw 1, a pull hammer 2 and a supporting frame with adjustable height;
The height-adjustable support frame consists of a screw sleeve 31, 2 support rods 32 and a bottom support, wherein the support rods are formed by connecting a vertical rod 33 and an inclined rod 34, the inclined rods of the 2 support rods are fixedly connected with the outer wall of the screw sleeve, a triangle is formed between the two inclined rods and a horizontal line, the bottom support frame is provided with two cavity rods 36 with screw holes 35 and locking screws and a connecting rod 37 for connecting the two cavity rods, the height-adjustable support frame further comprises moving wheels 38, the number of the moving wheels is 2, the moving wheels are arranged at the bottom ends of the cavity rods, the vertical rods of the support rods are inserted into the cavity rods, the screw rods are horizontally arranged, one ends of the screw rods are inserted into the screw rod sleeve, external threads 11 corresponding to the central screw holes of pin shafts of the underground scraper are arranged on the outer surfaces of the other ends of the screw rods, the pull hammers are arranged on the screw rods, the pull hammers are linear bearings, and hanging rings 21 are arranged on two sides of the pull hammers.
The using method of the device comprises the following steps:
When the screw rod is used, the height of the triangular height-adjustable support frame is adjusted by adjusting the length of the vertical rod inserted into the cavity rod of the support rod, then the locking screw is screwed down, so that the height of the screw rod is consistent with the height of the pin shaft to be disassembled, the moving directions of the two locking wheels are consistent with the running direction of the pin shaft, the front end of the screw rod is screwed into the central threaded hole of the pin shaft to be disassembled, the lifting ring is used for pulling the pull hammer, and the screw rod baffle is reciprocally hit, so that the impact force is transmitted from the screw rod to the pin shaft to be disassembled, and the pin shaft can be disassembled. The fixture is used for disassembling the pin shaft, so that the pin shaft which is embedded in a complex structure and is difficult to apply force and take out can be easily disassembled, and the integrity of the end face of the pin shaft can be protected.
