Stable gantry crane with anti-falling function

Abstract

The invention relates to a stable gantry crane with an anti-falling function. The stable gantry crane comprises a cross beam, a translation mechanism, a translation block, a lifting mechanism, a connecting mechanism, a processor and two supporting columns. The connecting mechanism comprises a sliding plate, a rope, a lifting hook, two sliding rings and two clamping plates, and the lifting mechanism comprises a lifting box, a rotating assembly, a roller and two protection assemblies, wherein the rotating assembly, the roller and the two protecting assemblies are arranged in the lifting box, andeach protecting assembly comprises an electromagnet, an iron plate, a clamping block, two telescopic units and a plurality of side rods. According to the stable gantry crane with the anti-falling function, stable lifting and moving of cargoes can be realized through the connecting mechanism, and therefore the cargoes can be prevented from shaking due to wind blowing in the carrying process; moreover, in the cargo lifting process, when the equipment is suddenly powered off, the protection assemblies can be used for clamping the side rods and fixing the angle of the roller, and cargo falling caused by continuous rope loosening is prevented; and the safety and reliability of the equipment operation are enhanced, and the practicability of the equipment is improved.

Description

technical field [0001] The invention relates to the field of construction equipment, in particular to a stable gantry crane with an anti-fall function. Background technique [0002] Gantry crane is a variant of bridge crane, also known as gantry crane. It is mainly used for the loading and unloading of outdoor cargo yards, stockyards and bulk cargoes. Gantry cranes have the characteristics of high site utilization, large operating range, wide adaptability and strong versatility, and are widely used in port cargo yards. Its metal structure is like a door-shaped frame. Two right angles are installed under the bearing main beam, which can walk directly on the track on the ground. The two ends of the main beam have outrigger cantilevers. [0003] When the existing gantry crane is carrying out transportation work, it mainly relies on the hook to hook the goods, and then the hoist tightens or loosens the rope to drive the hook and the goods to lift, and adjust the horizontal posi...

AI Technical Summary

Problems solved by technology

[0003] When the existing gantry cranes are transported, they mainly rely on the hook to hook the goods, and then the hoist tightens or loosens the rope to drive the hook and the goods to go up and down, and by adjusting the horizontal position of the hoist, the transportation position of the goods is adjusted. During the process, because the equipment is running outdoors, affected by the external environment, when the wind is strong, it is easy to blow the goods on the hook, causing the goods to shake, which affects the stability of the transportation, and during the operation of the equipment, if suddenly In the event of a power outage accident, the winch stops running and the rope is no longer tightened. At this time, the cargo is likely to fall to the ground, causing a safety accident, which in turn reduces the practicability of the existing gantry crane
