A device for preventing accidental opening of the side door of a self-rolling vehicle

Abstract

The invention belongs to the technical field of a vehicle tipping mechanism of a self-dumping car, and particularly relates to a device for preventing a side door from being accidentally opened for a self-dumping car. The device solves the problems to achieve the effects that in the vehicle operation process of the self-dumping car, the side door is prevented from being accidentally opened; the locking reliability of the side door is ensured; the accidental opening of the side door is prevented. The device comprises a gear seat, a thumb air cylinder, an air cylinder installing seat, a movable gear and an installing seat, wherein the installing seat is fixed at the outer part of the end wall of the self-dumping car; the installing seat is hinged to and connected with one end of the movable gear through a rotating shaft; the other end of the movable gear is provided with a gear hook; the gear hook is buckled on the gear seat; the gear seat is fixed on the side door of the self-dumping car; the thumb air cylinder is arranged at the lower side of the movable gear; the thumb air cylinder is connected with the movable gear through a pin shaft; the thumb air cylinder is arranged on the air cylinder installing seat; the air cylinder installing seat is fixed on the end wall of the self-dumping car. The device has the advantage that the operation safety of the vehicle is improved.

Description

technical field [0001] The invention belongs to the technical field of tipping mechanisms for self-rollover vehicles, in particular to a device for preventing accidental opening of a side door of a self-rollover vehicle. Background technique [0002] The existing tipping mechanism of the self-rollover vehicle is mainly the restraining elbow and the large folding structure (see figure 1 ). This mechanism is mainly for when the carriage is overturned, the side door on the overturned side is restrained by the elbow roller (see figure 1 ) along the fold (see figure 1 ) trajectory movement, gradually open. At the same time, the side door on the non-tipping side should keep its position unchanged under the action of restraining the elbow roller and hinge, and the side door should not move. However, for the assembled self-tipping vehicle, since the contact point between the roller and the hinge root of the side door is close to the top, when the tilting starts, the side door on...
