Liftable transverse beam for bridge crane and operation method

Abstract

The invention discloses a liftable transverse beam for a bridge crane and an operation method. The liftable transverse beam comprises two bottom plates, wherein supporting mechanisms are arranged on the outer walls of the tops of the two bottom plates. Each supporting mechanism comprises two supporting plates, wherein the two supporting plates of each supporting mechanism are welded to the outer walls of the two ends of the top of the corresponding bottom plate, a transverse plate is arranged above each bottom plate, the two ends of each transverse plate are welded to the outer walls of the tops of the two corresponding supporting plates, and lifting mechanisms are arranged on the outer walls of the tops of the two transverse plates correspondingly. Each lifting mechanism comprises a supporting frame, wherein the bottom of each supporting frame is welded to the outer wall of the top of the corresponding transverse plate, a sliding plate is installed in each supporting frame in a sliding mode, a supporting column is welded to the outer wall of the top of each sliding plate, and a limiting frame is welded to the inner wall of the top end of each supporting frame. According to the liftable transverse beam for the bridge crane and the operation method, the stability is improved, the overall supporting strength of a device is improved, the height of a guide rail can be adjusted, the bridge crane can be suitable for hoisting occasions with different heights, the flexibility is improved, fixing blocks and the guide rail can be supported, the guide rail is prevented from being inclined, and the safety is improved.

Description

technical field [0001] The invention relates to the technical field of bridge cranes, in particular to a liftable crossbeam for bridge cranes and an operation method. Background technique [0002] The bridge crane is a lifting device that is horizontally placed over the workshop, warehouse and stockyard for material lifting. Because its two ends are located on tall cement columns 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 and the largest number. [0003] After retrieval, the Chinese patent application number is 201920413172.X, and the patent publication number is CN210048392U, which discloses a liftable beam for bridge cranes. The above-mentioned device can not only realize the pa...

[0003] After retrieval, the Chinese patent application number is 201920413172.X, and the patent publication number is CN210048392U, which discloses a liftable beam for bridge cranes. The above-mentioned device can not only realize the parallel lateral movement of the beam, but also combine the liftable mechanism to realize the beam It can be adjusted up and down to adapt to the lifting and hoisting of different goods, which greatly improves the practicability, effectively realizes the lifting of the beam, facilitates the operation of the bridge crane, and effectively realizes the lifting needs of various goods. However, the above-mentioned device is in use In the process, there is a disadvantage of low stability, and the whole device is easy to topple over. At the same time, when the beam of the above device is raised and lowered, there is no fixing mechanism. As a result, after the beam is raised, the weight of the beam as a whole acts on the two lifting support rods. The stability is not high, it is easy to cause the beam to tilt or even bend the lifting support rod
