Embodiment Construction

[0017] combined with Figure 1-4 The automatic deviation correction device of the crane is described in detail. The automatic deviation correction device of the crane includes an industrial computer, two free wheels and two encoders respectively arranged on the two free wheels. On the beam, the corresponding positions on the two walking beams are provided with proximity switches in pairs, and the signal output ends of the proximity switch and the encoder are all connected to the signal input end of the industrial computer. The relative positions on both sides of the two parallel tracks are respectively provided with detection and setting points. There are at least two proximity switches, and the industrial computer is also connected with a buzzer, which will automatically alarm when the deviation is exceeded. The free wheel can be a driving wheel, a driven wheel or an additional wheel for running synchronously with the driving wheel.

Abstract

The invention relates to an automatic correction device for a crane. The automatic correction device comprises an industrial personal computer, two free wheels and two encoders arranged on the two free wheels respectively, wherein the two free wheels are respectively arranged on two walking beams in a rolling manner, the walking beams walk on two parallel tracks of the crane, and the signal output ends of the two encoders are both connected with the signal input end of the industrial personal computer; in running, a traveling crane drives the two free wheels to walk and respectively drive the two encoders to work, the two encoders output signals to the industrial personal computer, the industrial personal computer calculates the rotation speed of the two encoders so as to judge whether the two walking beams are synchronous, if no, the industrial personal computer outputs a control command to automatically realize the synchronous running of the two walking beams.. The automatic correction device not only improves the correction efficiency, and reduces the hidden safety correction danger, but also can monitor the running state of the crane in real time, and conduct automatic correction in real time.

Description

technical field [0001] The invention belongs to the technical field of crane deviation correction, and relates to an automatic deviation correction device for a crane. Background technique [0002] The automatic deviation correction device technology is a supporting product with large span, high lifting height or needs deviation correction technology. When working on a large-span crane, due to the large span, the outriggers on both sides will lead or lag behind after a long period of operation, which will deform the main beam and seriously affect the service life of the crane. In order to solve this problem. Users put forward stricter requirements for deviation correction technology. The traditional method is to rely on manual operation and instrument measurement and adjustment. However, the crane runs frequently, which is not only inefficient, but also has serious safety hazards. The automatic deviation correction device overcomes the above disadvantages, and can monitor t...
