Description

Gantry crane with windproof fixing structure Technical Field The utility model particularly relates to the technical field of portal cranes, in particular to a portal crane with a windproof fixing structure. Background The lifting mechanism provides power through a motor according to the weight and lifting height requirements of cargoes, drives the winding drum to rotate after the speed reduction and torque increase of the speed reducer, and realizes lifting movement of the lifting hook by utilizing the transmission of the steel wire rope and the pulley block so as to finish the operations of lifting, carrying, placing and the like of the cargoes; At present, the traditional portal crane is mostly used in ports or wharfs for hoisting and transferring large-scale equipment, thus the crane is required to be used in a severe scene, the heavy wind weather often exists in the ports or wharfs, the distance between the traditional crane hoisting device and the ground is larger, when the heavy wind weather works, the equipment is influenced by heavy wind, the large-amplitude shaking can be caused, the safety during the working is influenced, even the working state of the crane is influenced, the shutdown is caused, According to the retrieval, chinese patent publication No. CN202323366393.1 discloses a novel windproof crane, which comprises a gantry crane frame consisting of a main beam and supporting legs arranged on two sides of the main beam, wherein two fixed electric hoists are arranged on the main beam, each electric hoist comprises a rope and a lifting appliance, and the novel windproof crane is characterized in that a windproof device is arranged on each supporting leg, each windproof device comprises a sliding chute arranged on each supporting leg, a transverse plate and a connecting rod, the ropes penetrate through the transverse plates, a protective shell is arranged below each transverse plate, a protective cavity is arranged on each protective shell, a first sliding block and a second sliding block are arranged in each sliding chute in a sliding manner, each transverse plate is fixedly connected with each first sliding block, one end of each connecting rod is hinged with each second sliding block, the other end of each connecting rod is hinged with a supporting block, each transverse plate is provided with a movable groove, each supporting block is slidably arranged in each movable groove, a first spring is arranged between each supporting block and each movable groove, and a supporting assembly is arranged at the bottom of each sliding chute; When the device in the above patent is used, though the shaking of the rope is effectively reduced through the wind-proof device, the rope cannot be stable like a working surface in a windless state during working, when the lifting device slightly shakes, a workpiece at the bottom can shake greatly, and therefore, a large acting force can be generated between the workpiece and a clamp at the bottom of the lifting device, and therefore separation between the workpiece and the lifting device is caused, and production efficiency is affected.
