Anti-extrusion device and high-altitude operation machine

Abstract

The invention discloses an anti-extrusion device. The anti-extrusion device comprises a movable mechanism, fixed mechanisms and a position signal detection mechanism, wherein the movable mechanism comprises a collision rod and movable frames; the two ends of the collision rod are connected with the movable frames respectively; a plurality of elastic elements are arranged between the movable framesand the inner walls of the fixed mechanisms and surround the movable frames; rod sections at the two ends of the collision rod are hinged to the fixed mechanisms respectively; the rod sections can rotate around a public sphere center relative to the corresponding fixed mechanisms, so that the collision rod can respond to extrusion thrust exerted on an operator and freely rotate; after the extrusion thrust disappears, the collision rod is automatically recovered to an initial state under the action of the elastic elements; and the position signal detection mechanism is mounted to detect and transmit a movable position signal of the collision rod, so that a control unit can perform control operation based on the movable position signal. The invention further discloses a high-altitude operation machine. The anti-extrusion device can be triggered in all directions, has an automatic resetting function, and is low in cost and high in reliability.

Description

technical field [0001] The invention relates to a safety protection device, in particular to an anti-extrusion device. In addition, it also relates to a high-altitude working machine provided with the above-mentioned anti-extrusion device. Background technique [0002] The working platform is usually installed on the lifting operation machine, and the working platform is used to accommodate the operator. The operating platform is usually installed on the working platform, and the operating platform is fixed on the side of the working platform facing forward along the main movement direction of the machine, so that the operator can carry out corresponding operations. Operation. [0003] For this type of equipment, there is a risk of crushing injury to the operator during operation; for example, for aerial work machinery (tower cranes, elevators, etc.), if the operation platform is moving, if the operation is careless, it will not be noticed When there is a large obstacle in...
