Description

Simple disc puller Technical Field The utility model belongs to the technical field of disassembly tools, and particularly relates to a simple disc puller. Background The disc puller is a tool for removing disc-shaped parts from shaft parts, is used as a machine pump maintenance personnel of a maintenance center, is frequently disassembled for parts such as a motor impeller, a small bearing and the like in the daily maintenance operation process, and is researched to solve the problems in order to improve the working efficiency, for example, the Chinese patent application No. CN201320609854.0 discloses the disc puller which consists of a fixed disc and a jack, wherein the fixed disc is a disc, 3 or 4 pairs of fixed arms are uniformly arranged on the periphery of the side surface of the fixed disc, the fixed disc and the fixed arms are in an integral structure, each pair of fixed arms are hinged with a pulling claw, the pulling claw is an integral rod-shaped structure formed by a front rod, a rear rod and a claw hook, the lengths of the front rod and the rear rod are equal, an included angle is formed between the front rod and the rear rod, the top ends of the claw hooks face one side of the front rod and the rear rod, and all the claw hooks face one side of the disc center. The disc puller has the advantages of simple structure, quick operation, time saving and labor saving. Overcomes the defects of time and labor waste of the existing manual disc puller, avoids the complex structural design of the existing automatic disc puller, and reduces the cost. However, the automatic (hydraulic jack) disc puller is difficult to carry in daily maintenance of the pump, and the sizes of the internal parts of the pump are different, so that the position adjustment of the hook of the disc puller is difficult, and the dismantling of the parts of the pump with multiple sizes cannot be satisfied. Disclosure of Invention Based on the above, the application provides a simple disc puller, which solves the problems that the automatic (hydraulic jack type) disc puller is difficult to carry in daily maintenance of a pump, and the sizes of internal parts of the pump are different, so that the hook position of the disc puller is difficult to adjust, and the dismantling of the parts of the pump with multiple sizes cannot be satisfied. The technical scheme for solving the technical problems is as follows: A simplified disc puller comprising: the device comprises a fixing plate, a supporting component and a fixing component, wherein a first threaded hole is formed in the fixing plate, a first screw rod is in threaded fit with the first threaded hole, the first screw rod can move up and down along the vertical direction, the supporting component is arranged on two sides of the fixing plate and can move up and down along the vertical direction, the fixing component comprises at least two connecting ropes, one ends of the connecting ropes are connected with the fixing plate in a sliding mode, the other ends of the connecting ropes are fixedly connected with hooks, and the hooks are used for fixing pump parts.
