Embodiment Construction

[0010] As shown in the accompanying drawings, the left and right end beams 2 are fixed at both ends of the girder 1 respectively, and the front and rear large wheels 5 are respectively fixed through the bearings under the left and right end beams 2, and the driving wheels of the front and rear large wheels 5 are coaxially fixed gears 4 , the gear 4 is driven by a reducer and a motor, and an anti-off steel plate 7 is respectively fixed on the end beam 2 near the inner side of each large wheel 5 . The gap between the anti-off steel plate 7 and the big wheel 5 is no more than 1.5mm. The size of the anti-shedding steel plate 7 is 10mm thick, 150mm long, and 80mm wide.

[0011] Proximity switches 3 are respectively fixed on the left and right end beams 2 close to the gear 4, and the proximity switches 3 are electrically connected with the control mechanism of the electric single-girder hoisting large wheel 5. When the detection signals input by the left and right proximity switche...

Abstract

The invention relates to a derailment-preventing device for big electric single-beam hanging wheels, wherein a left end beam and a right end beam are respectively fixed on two ends of a girder; a front big wheel and a rear big wheel are respectively fixed under the left end beam and the right end beam through bearings; gears are coaxially fixed with driving wheels of the front and the rear wheels; the gears are driven by speed reducers and motors; and an anti-falling steel plate is respectively fixed on the end beams close to the inner side of each big wheel. The derailment-preventing device has a simple structure, and can effectively prevent the big electric single-beam hanging wheels from derailing.

Description

technical field [0001] The invention relates to a device for preventing falling of a large wheel of an electric single beam crane. Background technique [0002] The main structure of the electric single beam crane is composed of two end beams and a large beam. There are two large wheels on each end beam, one of which is a driving wheel and the other is a driven wheel. In use, when the cart motor, reducer, large wheel, and line fail, it will cause one of the two motors running together to run and one to stop, resulting in the derailment of the large wheel. Contents of the invention [0003] In order to overcome the shortcomings of the prior art, the present invention provides an anti-falling device for large wheels of an electric single-girder crane, which has a simple structure and can effectively prevent the large wheels of an electric single-girder crane from falling off the road. [0004] The technical solution adopted by the present invention to solve the technical p...
