Problems solved by technology

However, in many cases, due to the harsh working environment of the crusher or the excessive force on the pulley, the large pulley is rusted or deformed. It is difficult to remove it with the commonly used removal tools only by the rotation of the thread, and the female thread of the large pulley often appears If the belt pulley cannot be removed in time, it needs to be removed by smashing with a sledgehammer or bombing, which is more destructive to the crusher.

Abstract

The invention relates to a detaching tool for a big belt pulley. The detaching tool comprises a guiding sleeve, a hydraulic cylinder and an end cover, wherein the guiding sleeve comprises a plate body on the front part and a plurality of supporting rods connected to the plate body along circumference; the end cover is arranged on the tail parts of the supporting rods and is parallel and opposite to the plate body; the hydraulic cylinder is arranged between the plate body and the end cover and is located inside the supporting rods; an extended threaded section is arranged at the front end of the plate body; a through hole is formed in the middle of the plate body; and a piston rod of the hydraulic cylinder stretches in the through hole. The detaching tool for the big belt pulley comprises three parts: the guiding sleeve, the hydraulic cylinder and the end cover, and has convenience in detaching, taking, and combining and mounting on site, wherein clearances among the supporting rods onthe guiding sleeve are convenient for placing of the oil tubes on the hydraulic cylinder and the position of the hydraulic cylinder can be flexibly adjusted.

Description

technical field [0001] The invention relates to the technical field of maintenance tools for coal mine equipment, in particular to a large pulley removal tool. Background technique [0002] At present, known breaker belt pulley is to utilize the torque force of screw thread that pulley is pulled down. However, in many cases, due to the harsh working environment of the crusher or the excessive force on the pulley, the large pulley is rusted or deformed. It is difficult to remove it with the commonly used disassembly tools only by the rotation of the thread, and the female thread of the large pulley often appears If the belt pulley cannot be removed in time, it needs to be removed by smashing with a sledgehammer or bombing, which is more destructive to the crusher. Contents of the invention [0003] The object of the present invention is to provide a large pulley removal tool in order to solve the above problems. [0004] The technical solution of the present invention...
