Work platform extrusion preventing system, aerial operation platform and control method

Abstract

The invention provides a work platform extrusion preventing system, an aerial operation platform and a control method, and the technical problem that in the prior art, mistaken triggering is likely tohappen is solved. The work platform extrusion preventing system is arranged on a work platform. The work platform comprises an operation table, and an extrusion preventing pull rope located on the rear side of the operation table is included, wherein the two ends of the extrusion preventing pull rope are connected with the work platform. At least one end of the extrusion preventing pull rope is connected with a pull rope switch arranged on the work platform, the pull rope switch is connected with an upper controller, and the upper controller is provided with a platform action stop module. Thework platform extrusion preventing system, the aerial operation platform and the control method have the beneficial effects that the extrusion preventing pull rope connected with the pull rope switchis used for detecting the extrusion situation, the detection manner is a contact manner, and mistaken triggering is not likely to happen.

Description

technical field [0001] The invention belongs to the technical field of anti-extrusion systems, and in particular relates to an anti-extrusion system for a working platform, an aerial work platform and a control method. Background technique [0002] The aerial work platform is a product that serves mobile aerial work such as aerial work, equipment installation, and maintenance in various industries. The existing aerial work platform includes a fuselage, a walking device, a lifting device and a working platform. The working platform is arranged above the lifting device, and the lifting device is arranged on the fuselage. Drum-type lifting device, with a walking device on the fuselage. [0003] When the staff is working on the aerial work platform, if there is an obstacle above the platform and the machine continues to lift because the staff did not find it, the staff may be squeezed by the obstacle, and it is more likely that the staff will not be able to release it in time. ...

AI Technical Summary

Problems solved by technology

[0003] When the staff is working on the aerial work platform, if there is an obstacle above the platform and the machine continues to lift because the staff did not find it, the staff may be squeezed by the obstacle, and it is more likely that the staff will not be able to release it in time. Operate the handle to make the machine continue to lift, eventually causing more serious accidents

[0004] The existing anti-extrusion system generally uses a non-contact photoelectric sensor, but since the signal from the photoelectric sensor is invisible, the operator easily triggers the anti-extrusion system by mistake, which affects the use effect and reduces work efficiency
