Turnover protection method, turnover protection device and engineering mechanical equipment of cab

Abstract

The invention provides a turnover protection method of a cab, which is used for engineering mechanical equipment capable of turning over a cab of the equipment. The turnover protection method comprises the following steps: step 102, in which a control device acquires the opening and closing states of doors of the cab; and step 104, in which when at least one door of the cab is determined to be in an open state, the control device transmits a locking signal to a cab turnover mechanism, so that the cab turnover mechanism is in a locked state. Accordingly, the invention also provides a turnover protection device and the engineering mechanical equipment of the cab. With the adoption of the technical scheme of the invention, the falling-off of the doors caused by opening in the turnover process of the cab is avoided, so that the door damage and the personal casualty are prevented.

Description

Technical field [0001] The invention relates to the field of mechanical control, in particular to a turning protection method and a turning protection device of a cab, and a kind of engineering machinery equipment. Background technique [0002] The vehicle cab usually needs to be turned up for maintenance and repair of the engine and its surrounding components under the cab. The vehicle cab is relatively high and has a large turning angle. The inventor found at least the following problems in the prior art: [0003] When the cab is turned over, the user's negligence and failure to close the cab door and the mechanical failure of the door lock often occur, causing the door to suddenly fall after the cab is turned to a certain angle, causing casualties and damage to the door; [0004] Sometimes after the cab is turned to a certain angle, the user realizes or finds that the door is not locked. At this time, it is very difficult to open the door and then close it again. It is very diffi...

AI Technical Summary

Problems solved by technology

[0003] When the cab is turned over, it often occurs that the user neglects to close the cab door and the mechanical failure of the door lock, causing the door to suddenly fall after the cab is turned over to a certain angle, causing casualties and damage to the door;

[0004] Sometimes the user realizes or finds that the door is not locked after the cab is flipped to a certain angle. At this time, it is very difficult to open the door and close it again. big trouble

[0005] Therefore, there is a need for a new cab overturn protection technology, which can avoid the car door from falling off due to the opening of the car door during the cab overturning process, causing damage to the car door and casualties
