Abstract

A telescoping anti-collision device for a self-propelled type aerial working platform comprises a fixed square tube, a movable square tube and a limit switch. The fixed square tube is connected with the movable square tube in a sleeving mode, and the limit switch is arranged at the top end of the movable square tube; and the telescoping anti-collision device further comprises a limit switch installing base and a spring fixing base which is connected in the movable square tube, a connection portion of the limit switch installing base is linearly and movably connected in the movable square tube through a sliding rail structure, a buffer spring is arranged between the connection portion and the spring fixing base, and the limit switch is connected with an installing portion of the spring fixing base. The telescoping anti-collision device for the self-propelled type aerial working platform can effectively protect an operator, and danger, caused by a collision with a top obstacle, to the operator can be prevented; and meanwhile, the spring can have a certain buffer function after the limit switch makes contact with the top obstacle, and therefore the limit switch is prevented from being destroyed and losing efficacy due to inertia of the platform.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a retractable anti-collision device for a self-propelled aerial work platform. Background technique [0002] Self-propelled aerial work platforms are mainly used in the construction industry, warehouses, venue maintenance, etc., and are mainly composed of chassis, scissors, working platforms, hydraulic systems, electrical systems, etc. At present, when the self-propelled aerial work platform is working, when the operator is standing on the working platform, due to operational errors or accidents, the head of the working platform or the operator collides with the top of the building, causing danger. Existing anti-collision devices have a complete mechanical structure, which is not safe enough for engineering machinery, or is not retractable, and is inconvenient for walking or transportation. [0003] Another example is an anti-collision device for an aerial work pla...
