Large stroke combined type hydraulic jacking oil cylinder

Abstract

The invention discloses a large stroke combined type hydraulic jacking oil cylinder. The large stroke combined type hydraulic jacking oil cylinder comprises a single-acting multi-stage plunger oil cylinder, a double-acting oil cylinder and a pulling wire sensor used for detecting the position of a cargo tray, wherein the single-acting multi-stage plunger oil cylinder is installed above the double-acting oil cylinder, the pulling wire sensor is installed on a cylinder body of the double-acting oil cylinder, and a pulling wire inside the pulling wire sensor is connected with the top end of the single-acting multi-stage plunger oil cylinder. By means of the large stroke combined type hydraulic jacking oil cylinder, a short installation length can be realized, and a large working stroke can berealized, when jacking is performed on a weight, the weight can be made to reach different heights according to different height requirements, meanwhile, when the weight on the tray is moved to one other station, a jacking mechanism is made to retract a certain height quickly by controlling the jacking oil cylinder, the fact that the jacking oil cylinder does not interfere with the tray of the weight in horizontal moving of the weight is guaranteed, unnecessary work processes are finally reduced, the time for jacking the weight is saved, and the work efficiency is improved.

Description

technical field [0001] The invention relates to a jacking cylinder, in particular to a large-stroke combined hydraulic jacking cylinder, which is suitable for occasions where the difference between the installation distance and the working stroke is relatively large and the station needs to be rotated to the next station, and belongs to the multi-station The technical field of feeding mechanism for assembly line operation. Background technique [0002] The jacking cylinder is an important auxiliary mechanism in the lifting and transportation of heavy objects, which can reduce the physical labor of workers and improve work efficiency. At present, in construction sites and factory buildings, the lifting of heavy objects is mostly done by gantry or bridge cranes, which occupy a relatively large space and are limited by space, and can only be carried out under specific working conditions. At the same time, for those mechanisms that lift heavy objects vertically, the installatio...

Problems solved by technology

At present, in construction sites and factory buildings, the lifting of heavy objects is mostly done by gantry or bridge cranes, which occupy a relatively large space and are limited by space, and can only be carried out under specific working conditions.

At the same time, for those mechanisms that lift heavy objects vertically, the installation length is often longer, the working stroke is short, and the bottom needs to be fixed to the ground

When the jacking cylinder sends the heavy object to the specified height, when the heavy object is moved to other stations in the space level, it is easy to interfere with the lifting mechanism. If the lifting mechanism is removed, unnecessary trouble will be caused
