The present application relates to the technical field of coal mine equipment, and more particularly to a mine hoist guide wheel rope lining automatic online assembly mechanism, which comprises a portal frame, a guide wheel body, a feeding assembly, a feeding assembly and a press-fitting assembly. The portal frame is arranged on one side of the guide wheel body. The feeding assembly is used for conveying the guide wheel rope groove gasket. The feeding assembly is used for feeding the guide wheel rope groove gasket on the feeding assembly to the guide wheel body. The press-fitting assembly comprises a linear actuator, a high-frequency vibrator, an extended connecting rod, a knocking module and a position detection unit. The linear actuator is installed on the portal frame. The output end of the linear actuator is connected with the high-frequency vibrator. The output end of the high-frequency vibrator is connected with the knocking module. The position detection unit is arranged on the knocking module. In this way, the technical problem of high labor intensity and time-consuming and laborious work of workers in the prior art is solved.

The utility model discloses a novel vibrating screen structure that can improve and enhance screening efficiency, which comprises a base, a vibrating exciter round beam, longitudinal beams, a main channel steel, a screen mesh and bolts. The vibrating exciter round beam is horizontally and transversely arranged on the base, and five longitudinal beams are vertically arranged on the upper end face of the vibrating exciter round beam along the length direction of the vibrating exciter round beam. The main channel steel is horizontally and transversely arranged on the upper end face of the five longitudinal beams at the position close to the front end of the longitudinal beams, and the opening groove of the main channel steel is arranged in the forward direction. The screen mesh is horizontally arranged in the rectangular structure, and the left and right ends of the screen mesh are vertically upwardly turned up. The lower surface of the screen mesh is supported on the upper surface of the main channel steel at the position close to the front edge of the screen mesh, and a plurality of bolts are vertically arranged on the upper surface of the main channel steel along the length direction of the front edge of the screen mesh. The screen mesh and the main channel steel are fixed by the bolts. Then, the screen mesh is vibrated by the vibrating exciter round beam to perform the screening operation. The utility model effectively solves the problem of material sticking on the screen mesh under various working conditions of the lump ore.
