Rail-gnawing preventing end beam device and hoisting equipment

Abstract

The invention discloses a rail-gnawing preventing end beam device and hoisting equipment, and belongs to the technical field of hoisting equipment. The rail-gnawing preventing end beam device comprises an end beam body and a guiding mechanism. The end beam body comprises wheels rotationally arranged on the end beam body, and the wheels roll along a guide rail, namely the end beam body can move along the guide rail. The guiding mechanism comprises a box, a transmission shaft, a transmission wheel and a transmission rail. The box is arranged on one side of the end beam body, internally and rotationally provided with the transmission shaft and arranged at one end of the transmission shaft in a sleeving mode. The transmission wheel is configured to move on the transmission rail, and the transmission rail and the guide rail are arranged parallelly. The transmission shaft drives the transmission wheel to move on the transmission rail so that the wheels on the end beam body can move on the guide rail, and accordingly, the end beam device moves on the guide rail; and through matching of the transmission wheel and the transmission rail, the end beam body can be guided so as to enable the wheels and the guide rail not to make contact, and the rail-gnawing phenomenon is prevented effectively. The invention further provides the hoisting equipment applying the rail-gnawing preventing end beam device

Description

technical field [0001] The invention relates to the technical field of lifting equipment, in particular to an anti-gnawing rail end beam device and lifting equipment. Background technique [0002] At present, in the production of workshops, bridge-type lifting equipment is often used to move larger and heavier parts. like Figure 1-3 As shown, the traditional bridge lifting equipment includes a bridge frame 1', a bridge end beam 2', an end beam device 3' and a trolley 4', wherein the two ends of the trolley 4' are respectively arranged on two end beam devices 3', The two end beam devices 3' are respectively arranged on the bridge frame 1' on both sides, that is, the trolley 4' can move relative to the bridge frame 1', and the parts can be hoisted by the trolley 4' for transportation. In addition, the end beam device 3' is rotatably provided with wheels 5', the wheels 5' cooperate with the rails 6' provided on the bridge frame 1', and the two sides of the wheels 5' are respe...

AI Technical Summary

Problems solved by technology

However, in the actual use process, due to the influence of comprehensive factors such as uneven gravity distribution, out-of-synchronization of the end beam running motors on both sides, installation error of the track 6', and manufacturing and installation error of the end beam device 3', the trolley 4' is in the process of running. It will always deviate in one direction, and the rim 51' of the wheel 5' will rub against the track 6' in a rather long stroke, so that the rail gnawing phenomenon common to cranes occurs

Rail gnawing by the crane will accelerate the wear of the rail 6' and the wheel 5', seriously affecting the life of the rail 6' and the safe operation of the crane
