Total-travel reciprocating mechanism driven by hydraulic cylinders

Abstract

The invention relates to a total-travel reciprocating mechanism driven by hydraulic cylinders and belongs to the technical field of manufacture of special vehicles. The total-travel reciprocating mechanism comprises a framework, synchronization supports, hydraulic cylinders, sliding rails, sliding trolleys and the like and is characterized in that the synchronization supports are symmetrically mounted on the left side and the right side of the framework, a hydraulic cylinder I is mounted on the left side of the framework, a hydraulic cylinder II is mounted on the right side of the framework, the sliding rails are vertically symmetrically mounted on the framework, the sliding trolleys are vertically symmetrically mounted on the sliding rails through the synchronization supports, a pulley I is mounted at the end part of a piston rod of the hydraulic cylinder I, a pulley II is mounted at the end part of a piston rod of the hydraulic cylinder II, a chain I and a chain II wind around one end of the pulley I and one end of the pulley II to be connected with the framework, and the other ends are connected with the synchronization supports. The problem that hydraulic cylinders in the prior art are difficult to mount and use on existing total-travel reciprocating mechanisms due to the fact that the hydraulic cylinders are limited by the proportion of travel to the minimum mounting distance and the effective travel cannot exceed the minimum mounting distance is solved.

Description

technical field [0001] The invention relates to a full-stroke reciprocating mechanism driven by a hydraulic oil cylinder, which belongs to the technical field of special-purpose vehicle manufacturing. Background technique [0002] The full stroke reciprocating mechanism is a very important part for the forklift to realize vertical displacement and horizontal displacement. The hydraulic cylinder has many advantages such as compact structure, large force, stable operation and low failure rate, and is very suitable as a driving device for linear motion. The organic combination of the hydraulic cylinder and the full-stroke reciprocating mechanism can greatly increase the driving force of the full-stroke reciprocating mechanism and ensure the effective stroke of the forklift mast. However, the hydraulic cylinder is limited by the proportional relationship between its own stroke and the minimum installation distance, so that its effective stroke cannot exceed its minimum installa...

AI Technical Summary

Problems solved by technology

However, the hydraulic cylinder is limited by the proportional relationship between its own stroke and the minimum installation distance, so that its effective stroke cannot exceed its minimum installation distance and it is difficult to install and use it on the existing full-stroke reciprocating mechanism. Since the mechanical structure and stroke of the hydraulic cylinder cannot be changed, Therefore, it is very necessary to develop a model that can extend the effective stroke of the hydraulic cylinder close to the total length of the full-stroke reciprocating mechanism, avoiding the limitation of the minimum installation distance and stroke of the hydraulic cylinder on the effective stroke of the full-stroke reciprocating mechanism, simple structure, easy assembly, and improve the overall working efficiency of the forklift.
