Problems solved by technology

[0003] When there is a problem with the lifting mechanism of the traditional bridge crane during use, it is necessary to manually lift to a certain height with the help of a lift, and then repair the problematic part of the lifting mechanism on the crane. There is a certain degree of danger, not only that, it is very inconvenient to use the elevator for maintenance, and it is very inconvenient for some tools to be frequently replenished on the ground

Abstract

The invention discloses a lifting device used on a bridge crane. The lifting device comprises a transverse beam, a hoisting mechanism, two limiting and fixing mechanisms and two lifting mechanisms, wherein the hoisting mechanism is arranged on the transverse beam, a notch is formed in one side of the transverse beam, and a fixing block matched with the notch is arranged at the notch; a plurality of through grooves communicated with the notch are formed in the transverse beam, and the two lifting mechanisms are arranged at the two ends in the length direction of the transverse beam respectively. The two limiting and fixing mechanisms are arranged on the fixing block, steel cables are arranged between the fixing block and the lifting mechanisms, and the steel cables penetrate through the through grooves. Maintenance personnel are prevented from carrying out maintenance high above the ground, it is ensured that the maintenance personnel safely work, and the problem that inconvenience is brought when the maintenance personnel frequently come down to get tools is solved.

Description

technical field [0001] The invention relates to the technical field of crane equipment, in particular to a lifting device for a bridge crane. 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 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 and the largest number. [0003] When there is a problem with the lifting mechanism of the traditional bridge crane during use, it is necessary to manually lift to a certain height with the help of a lift, and then repair the problematic part of the lifting mechanism on the crane. Th...
