Abstract

The invention belongs to the field of mining machinery, and specifically relates to a belt pulley detachment and installation device comprising a machine frame capable of rising and falling. A base isarranged at the bottom of the center of the machine frame capable of rising and falling. A rotary table is arranged at the top end of the machine frame capable of rising and falling. A pair of bossesare arranged on the rotary table. A shaft penetrates through the pair of bosses. The shaft and the bosses are connected in a rotating manner. A rotary plate is fixedly arranged on the portion, between the bosses, of the shaft. Threads are arranged at the two ends of the shaft. A gripper is arranged at one end of the shaft and connected with the shaft in a threaded manner. A heavy object is arranged at the other end of the shaft to be used as a balance device. The gripper is composed of a base and touch rods. A threaded hole is formed in the center of the base. The shaft and the base are connected in a threaded manner. Two or more touch rods are fixedly arranged on the base. The tip of each touch rod is connected with a nut through a thread. By means of the belt pulley detachment and installation device, belt pulleys can be easily detached, the detachment efficiency is improved, installation of the belt pulleys can also be achieved, and a good assistance effect is achieved in the replacement operation of belt pulley shafts.

Description

technical field [0001] The invention belongs to the field of mining machinery, and in particular relates to a device for removing and installing a belt pulley. Background technique [0002] At present, the majority of domestic concentrators use jaw crushers for coarse and medium crushing operations, which are mainly composed of frame, movable jaw assembly (including eccentric shaft), fixed jaw, pulley and other transmission devices. When the motor drives the belt pulley to rotate, at the same time the eccentric shaft drives the movable jaw to perform a pendulum motion, and the ore enters the crushing chamber and is squeezed and split by the movable jaw to achieve the purpose of ore crushing. However, since the eccentric shaft is the main transmission wear part, the general service life is about 1.5 years, so the crusher needs to complete maintenance and replacement reasonably according to the usage conditions. Because the eccentric shaft is installed in the movable jaw shaf...
