An Auxiliary Fixing Mechanism Supported by a Cantilever Column of a Portal Crane

Abstract

The invention discloses an auxiliary fixing mechanism for supporting a cantilever column of a portal crane, which comprises a crane body and a cantilever. A hoisting mechanism is fixedly installed at one end of the cantilever away from the crane body, and a support frame is fixedly installed at the bottom end of the crane body. And the number of the support frames is four, and the bottom ends of the support frames are all provided with walking carts. The present invention is provided with a first mounting frame, a first connecting rod, a support rod, a hydraulic telescopic rod, a second mounting frame, a second connecting rod and a support table, so that when the support rod works and shrinks inward, the support rod and the first A connecting rod and a second connecting rod are hinged through the rotating shaft, so when the support rod is retracted inward, the end of the first connecting rod and the second connecting rod away from the support frame is driven to move downward, so that the support rod moves downward, Therefore, it is fitted with the ground, the area of ​​the device in contact with the ground is increased, and the supporting frame is supplemented to support the upright column of the device.

Description

technical field [0001] The invention relates to the technical field of portal cranes, in particular to a supporting auxiliary fixing mechanism for a cantilever column of a portal crane. Background technique [0002] A jib crane in which the bridge frame is supported on the ground track or foundation through the outriggers on both sides. It has a track running along the ground, and can pass railway vehicles or other ground vehicles below. A jib crane with a rotatable lifting device mounted on a portal frame. The 4 legs of the portal frame form 4 "door openings" for railway vehicles and other vehicles to pass through. Most of the portal cranes run along the crane track on the ground or on the building to carry out lifting and unloading operations. In order to maintain the mobility of the existing portal cranes, the bottom end of the column is mostly equipped with a traveling car, which is convenient for the overall movement of the device. As a result, the connection between...

Problems solved by technology

[0003] The purpose of the present invention is to provide a cantilever column support auxiliary fixing mechanism of a portal type crane to solve the problem that the existing portal type cranes proposed in the background technology are mostly equipped with a trolley at the bottom of the column in order to maintain its mobility. The overall movement of the device leads to the problem that the connection between the whole device and the ground is not stable enough
