A walking mechanism for accompanying double-girder dispatching crane

Abstract

The invention discloses a following type walking mechanism for a double-beam dispatching and transporting crane, and belongs to the technical field of crane machines. The following type walking mechanism comprises a cross beam, wherein transmission cases are both mounted at the two ends of the cross beam; each transmission case comprises a front cover and a rear cover; a first wheel body, a secondwheel body and a third wheel body are arranged between each front cover and each rear cover; each first wheel body comprises a bearing and a wheel; a plurality of rectangular groove openings are formed in one side of the corresponding front cover while a horizontal groove is formed in the other side of the corresponding front cover; the corresponding first wheel body, the corresponding second wheel body and the corresponding third wheel body are fixedly connected with each other through connecting wrenches; a pair of end plates are arranged between the two connecting wrenches; each end plateis fixedly connected with an electromagnetic pull plate and a piston rod; a transmission shaft is mounted on each rear cover; each transmission shaft is in belt connection with each rotating shaft through a corresponding belt. According to the following type walking mechanism for the double-beam dispatching and transporting crane disclosed by the invention, positions of the wheel bodies are controlled, so that a stress state of horizontal walking of the crane is changed, the wheel bodies are effectively protected, and the service life of the wheel bodies is prolonged.

Description

technical field [0001] The invention belongs to the technical field of hoisting machinery, and particularly relates to a traveling mechanism for an accompanying double-girder transfer crane. Background technique [0002] At present, a crane refers to a multi-action hoisting machine that vertically lifts and horizontally transports heavy objects within a certain range. Also known as overhead cranes, aerial cranes, cranes, bridge cranes are lifting equipment that is horizontally placed over workshops, warehouses and stockyards for material hoisting. Because its two ends sit on tall concrete columns or metal supports, it is shaped like a bridge. The bridge of the bridge crane runs longitudinally along the track laid on the elevated on both sides, which can make full use of the space under the bridge to lift materials without being hindered by ground equipment. It is the most widely used and the largest number of hoisting machinery, and the existing bridge crane's moving wheel...

AI Technical Summary

Problems solved by technology

It is the most widely used and the largest number of hoisting machinery, and the existing bridge crane's driving wheel is in direct contact with the track, and the bridge crane often starts and brakes during work, making the friction frequency of the wheel and the track increase, decrease the service life of the device
