Problems solved by technology

It is a kind of hoisting machinery with the widest range of use and the largest number. It is a kind of bridge type crane whose bridge frame runs on the elevated track, also known as the crane. The bridge frame of the bridge crane runs longitudinally along the tracks laid on the elevated rails on both sides. , the lifting trolley runs horizontally along the track laid on the bridge frame to form a rectangular working range, which can make full use of the space under the bridge frame to lift materials without being hindered by ground equipment. Wheel sets are essential for bridge cranes A kind of equipment, but some current wheel sets cannot be quickly disassembled during work, and once damaged, it is difficult to repair, and ordinary wheel sets brake slowly, which is not conducive to the precise control of the crane

Abstract

The invention discloses a bridge type crane wheel set structure comprising wheels, a bearing box and wheel axles. The bearing box is mounted on the surfaces of the wheel axles, the wheels rotate around the wheel axles through bearings and comprise first wheel discs and second wheel discs, and the first wheel discs and the second wheel discs are connected together through connecting shafts. Connecting holes are formed in the surfaces of the first wheel discs and the second wheel discs correspondingly, positioning screws are connected to the two ends of the connecting shafts correspondingly andfixed to the surfaces of the first wheel discs and the second wheel discs through nuts, and circular grooves are formed in the outer sides of the first wheel discs and the second wheel discs correspondingly. Metal pieces are arranged on the inner walls of the grooves, a locking table is arranged on the surface of the bearing box, and a hydraulic rod is connected to the side face of the surface ofthe locking table. The outer end of the hydraulic rod is connected with a circular disc, and an electromagnetic coil is arranged in the circular disc. The bridge type crane wheel set structure is convenient to dismount on the whole, assembly and maintenance are more convenient, rapid braking can be achieved, positioning is more rapid, safety and accuracy are greatly improved, and the bridge type crane wheel set structure is worth popularizing.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a wheel set structure of a bridge crane. Background technique [0002] The bridge crane is a lifting device that is placed horizontally 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 is laid along the The tracks on the elevated sides on both sides run longitudinally, which can make full use of the space under the bridge to lift materials without being hindered by ground equipment. It is a kind of hoisting machinery with the widest range of use and the largest number. It is a kind of bridge type crane whose bridge frame runs on the elevated track, also known as the crane. The bridge frame of the bridge crane runs longitudinally along the tracks laid on the elevated rails on both sides. , the lifting trolley runs horizontally ...
