The invention discloses a high and low altitude operation vehicle leveling mechanism and a high and low altitude operation vehicle. The high and low altitude operation vehicle comprises a lifting arm,a lifting fork and an operation platform; the lifting fork comprises a lifting fork-lifting arm connecting part and a lifting fork-operation platform connecting part; the middle part of the lifting fork-lifting arm connecting part is connected with the end part of the lifting arm; the two ends of the lifting fork-operation platform connecting part are both connected with the end part of the operation platform; the leveling mechanism comprises a motor and a speed reducer; the speed reducer is connected to the upper edge of the operation platform; the end part of the motor is connected with thespeed reducer; a power output shaft of the motor is connected with an input end of the speed reducer; an output end of the speed reducer is connected with the lifting fork-lifting arm connecting part; and the motor is connected with a power device used for driving the motor to rotate. According to the high and low altitude operation vehicle leveling mechanism and the high and low altitude operation vehicle, by controlling the hydraulic motor, the angle of the operation platform relative to a horizontal position is adjusted by using the speed reducer so that the operation platform is always kept in a vertical state. According to the high and low altitude operation vehicle leveling mechanism and the high and low altitude operation vehicle, through a self-locking function of a worm and gearspeed reducer, the operation platform can also be fixed to prevent the operation platform from shaking when the hydraulic motor fails to work.
Description
technical field [0001] The invention relates to a leveling mechanism of a high and low altitude work vehicle and the high and low altitude work vehicle, belonging to the technical field of high and low altitude work vehicles. Background technique [0002] The high-altitude operation vehicle is a special equipment that can complete high-altitude and low-altitude operations. The operation platform needs to reach the designated work position to complete the specified operations, such as the maintenance of high-altitude street lights, low-altitude bridge inspection and other work content. When the working platform is working, the working platform is lifted to the working position by the lifting arm. During the lifting process, the working platform must always be kept in a horizontal state, but because the angle of the lifting arm relative to the horizontal plane is constant during the lifting process Therefore, the angle between the working platform and the lifting arm is changi...
