A linkage mechanism for accompanying double-girder transfer crane

Abstract

The invention discloses a linkage mechanism for accompanying type double-beam hoisting and transporting cranes, and belongs to the technical field of hoisting machinery. The linkage mechanism comprises a first cross beam, a second cross beam, a first piston rod and a second piston rod, wherein control rooms are arranged at the same ends of the first cross beam and the second cross beam correspondingly, connecting clamp seats are arranged on the opposite faces of the control rooms, and a linkage rod is cooperatively arranged between the two opposite connecting clamp seats; and the linkage rod comprises a first connecting rod, a second connecting rod and a shock absorber, the shock absorber comprises a hollow column, an end cover, a first separation plate and a second separation plate, a first two-way valve, a second two-way valve and a third two-way valve are the same in structural design, and the elastic coefficients of elastic elements in the first two-way valve, the second two-way valve and the third two-way valve are gradually decreased. According to the linkage mechanism for the accompanying type double-beam hoisting and transporting cranes, a buffering mechanism is arranged between the accompanying type double connected traveling cranes, so that positions of the parallel traveling cranes are limited, and stability and safety of hoisting are improved.

Description

technical field [0001] The invention belongs to the technical field of hoisting machinery, in particular to a linkage mechanism for an accompanying double-girder transfer crane. Background technique [0002] A crane refers to a multi-action hoisting machine that lifts vertically and carries heavy objects horizontally within a certain range. Also known as cranes, aerial cranes, cranes, bridge cranes are lifting equipment that are horizontally placed over workshops, warehouses and stockyards for material lifting. Because its two ends are located on tall concrete pillars or metal supports, it is shaped like a bridge. The bridge frame of the bridge crane runs longitudinally along the tracks laid on the elevated sides on both sides, which can make full use of the space under the bridge frame to lift materials without being hindered by ground equipment. It is a kind of hoisting machinery with the widest range of use and the largest number. When the objects retrieved by the crane...

AI Technical Summary

Problems solved by technology

It is a lifting machine with the widest range of use and the largest number. When the objects retrieved by the crane are large in size, and the objects are swaying and unstable during the driving process, two cranes are required to retrieve them at the same time, but At the start of the crane, the start of the two cranes is not synchronized, and the distance between the two cars will be opened or shortened instantly, causing the lifting objects to fall off.
