Problems solved by technology

[0002] The positioning machine is proposed to solve the problem of complete institutionalization of the installation and positioning of the underground hydraulic support. For a long time, the installation and positioning have been in a backward manual operation state, with strong labor, low work efficiency and many safety hazards. Change this The noise in this state is very high, and all levels and departments are actively developing, but so far there is still no competent machine. The rotary mechanism and the lifting mechanism on the existing positioning machine are set separately, not only the mechanism is complicated, but also the operation is relatively difficult. cumbersome and low work efficiency

Abstract

The invention provides an integrated lifting mechanism of a hydraulic cylinder of a rotary table, and belongs to the technical field of hydraulic arming machine. The technical problem that an integrated lifting mechanism, which is simple in structure, convenient to operate and high in working efficiency, of a hydraulic cylinder of a rotary table is provided is needed to solve. Aiming to solve the technical problem, according to the technical scheme, a supporting inner ring is arranged on a bottom plate and is sleeved on a supporting outer ring through a bearing; the supporting inner ring and the bottom plate form a cylinder body of a hydraulic cylinder; the bottom end of a piston rod of the hydraulic cylinder is provided with a piston; the supporting inner ring is arranged on the bottom plate and form the cylinder body of the hydraulic cylinder with the bottom plate for lifting, and the hydraulic cylinder piston and the piston rod which are used for lifting are arranged with a bearing platform in a conjoint manner; when liquid is discharged, a piston cylinder of the hydraulic cylinder falls. The integrated lifting mechanism is simple in structure, a rotary mechanism and the lifting mechanism are integrated, operation is facilitated, and working efficiency is high.

Description

technical field [0001] The invention discloses a rotary table hydraulic cylinder integrated lifting mechanism, which belongs to the technical field of hydraulic positioning machines. Background technique [0002] The positioning machine is proposed to solve the problem of complete institutionalization of the installation and positioning of the underground hydraulic support. For a long time, the installation and positioning have been in a backward manual operation state, with strong labor, low work efficiency and many safety hazards. Change this The noise in this state is very high, and all levels and departments are actively developing, but so far there is still no competent machine. The rotary mechanism and the lifting mechanism on the existing positioning machine are set separately, not only the mechanism is complicated, but also the operation is relatively difficult. It is cumbersome and the work efficiency is low. Contents of the invention [0003] The invention overc...
