Problems solved by technology

[0003] At present, due to the different lengths of the four steel wire ropes 12 of the main coil, the length judgment of the four steel wire ropes 12 is completely dependent on human vision. Length, so that it reaches the purpose of balancing the force of the four steel wire ropes 12. It takes about 120 minutes to readjust the length of the steel wire ropes 12 to make the balancer 4 balance, which is time-consuming and laborious.

Abstract

The invention discloses a steel wire rope length measuring device for a bridge crane. The steel wire rope length measuring device comprises a driving pulley, a driven pulley, two connecting plates, adetector and a digital display instrument, wherein the driving pulley is fixed on a transmission shaft and can drive the transmission shaft to rotate together, the driven pulley is installed on a screw rod and can rotate around the screw rod, the two connecting plates are connected with two sides of the transmission shaft and the screw rod, the detector is connected with one end of the transmission shaft, the digital display instrument is connected with the detector through a wire, the driving pulley and the driven pulley are horizontally installed, a gap is formed between the driving pulley and the driven pulley, a steel wire rope on a steel wire rope roll can penetrate through the gap and can be wound around a winding drum of the crane, the gap can clamp the steel wire rope, and at leastone of the screw rod and the transmission shaft is detachably connected with the connecting plates. The steel wire rope length measuring device for the bridge crane can automatically measure the length of the steel wire rope on line, and can adjust the lengths of a plurality of steel wire ropes to be the same at one time without secondary adjustment.

Description

technical field [0001] The invention relates to the technical field of bridge cranes in the metallurgical industry, in particular to a measuring device for the length of steel wire ropes of bridge cranes. Background technique [0002] In large-tonnage bridge cranes in the metallurgical industry, there are generally four steel wire ropes 12 for main lifting, and the steel wire ropes 12 are wound on a reel to move the hook up and down to extract heavy objects. Two steel wire ropes 12 are fixedly wound on one reel, and the ends of the two steel wire ropes 12 are respectively fixed on both sides of the reel. Wire rope 12 rope tail heavy-duty collars 13 are connected and fixed on the hook balancer 4 with pin shafts, as Figure 4a , 4b and Figure 8 shown. A reel, two steel wire ropes 12, and a balancer 4 are a group. And main hoisting is two reels 4 wire ropes 12 two balancers 4. When changing steel wire rope 12, must 4 steel wire ropes 12 change simultaneously, ensured safe...
