Abstract

The utility model relates to the field of an overhead working truck, which is a two-arm cylinder hoisting device of the overhead working truck. An upper fulcrum of the two-arm cylinder is installed in a two-arm square pipe and linked with the two-arm through a shaft pin; a lower fulcrum of the two-arm cylinder is linked with one arm through a linking base. Owing to the technical scheme with simple structure, rotary moment and rotary included angle are increased than before; meanwhile, the load of the two-arm cylinder when the two arms are hoisted is reduced; vibration of the two arms when hoisted is eliminated; the safety of the operation is guaranteed.

Description

Aerial platform two arm elevating ram devices
Technical field
The utility model relates to the aerial platform field, is a kind of aerial platform two arm elevating ram devices.
Technical background
The last fulcrum of two arm oil cylinders of former aerial platform makes that the angle in hinge axle center of oil cylinder and arm is less under two arms, near the dead point, be easy to generate shake in the lifting process, causes potential safety hazard.
Summary of the invention
The purpose of this utility model is mounting means and the position that a kind of new aerial platform two arm elevating rams will be provided.
The utility model is achieved in that the last fulcrum of two arm oil cylinders is installed in the two arm rectangular tubes, links by pivot pin and two arms, and the lower fulcrum of two arm oil cylinders links by a coupling seat and an arm.
Owing to adopted technique scheme, the utility model is simple in structure, makes rotating torque and rotation angle than increasing in the past, has reduced the load of two arm oil cylinders when lifting two arms simultaneously, has also eliminated the shake of two arms when lifting, and has guaranteed the safety of operation.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
In the drawings: 1, vehicle frame; 2, an arm; 3, coupling seat; 4, two arm oil cylinders; 5, pivot pin; 6, two arms.
The specific embodiment
