Aerial platform vehicle work platform leveling device with platform tiling prevention function

Abstract

The invention discloses an aerial platform vehicle work platform leveling device with a platform tiling prevention function. A working platform is hinged to an arm I through a shaft I, the arm I is hinged to an arm II through a shaft II, an arm X at the bottommost is hinged to a rotating table through a shaft X+1, and a forward leveling wheel I,... until a forward leveling wheel X+1, a reverse leveling wheel I,... until a reverse leveling wheel X+1 are arranged on a hinge shaft of every two arms; the upper end of a forward inhaul cable and the upper end of a reverse inhaul cable are fixed to the working platform; the forward inhaul cable sequentially passes through the outer edge of the forward leveling wheel I... until the lower end of the outer edge of the forward leveling wheel X+1 and is connected to the rotating table; the reverse inhaul cable sequentially passes through the inner edge of the reverse leveling wheel I ... until the lower end of the inner edge of the reverse leveling wheel X+1 and is connected to the rotating table; and according to the device, the working platform is adjusted to be in the horizontal state so as to facilitate aerial work, tilting caused by conditions of motion impact or the external force effect of the working platform and the like can be prevented, the structural principle is simple, the manufacturing cost is low, mounting and adjusting are convenient, and leveling is continuous and stable.

Description

technical field [0001] The invention relates to a leveling device for a working platform of an aerial work vehicle with the function of preventing the platform from tipping over, and belongs to the technical field of aerial work vehicles. Background technique [0002] An aerial work vehicle is a device used to transport personnel, tools and materials to a designated location at high altitude for work. When the working platform is working on the aerial work vehicle, it needs to be kept in a horizontal state at all times to ensure that the platform operators can perform high-altitude operations stably and safely. Therefore, it is necessary to set up a working platform leveling device. The included angle of the frame keeps the working platform level at all times. Existing folding aerial work vehicles mostly adopt two forms of parallelogram connecting rod leveling or chain sprocket leveling. Both of these two forms maintain balance with the gravitational moment of the working ...

Problems solved by technology

The working principle of this mechanism is correct, but the structure is complicated, and the installation and adjustment are very inconvenient. It is necessary to adjust the length of each connecting rod. The mechanism itself is an over-positioning device, and the length error will cause damage to the mechanism due to internal force, which will lead to failure of the mechanism. possibility of
