Description

Technical Field

[0001] The utility model relates to the technical field of remote control devices, in particular to a movable small-sized aerial work vehicle remote control system. Background Art

[0002] The mobile small aerial work vehicle is a convenient, efficient and safe working equipment, which is widely used in various aerial work fields, such as electricity, street lights, municipal administration, gardening, communications, airports, shipbuilding (repair), transportation, advertising, photography, etc. This equipment can provide workers with the convenience of reaching the aerial work position while ensuring their work safety.

[0003] Small mobile aerial work vehicles usually adopt a folding boom structure, with key components such as working arm, slewing structure, and center swivel joint. The working arm usually consists of an upper folding arm, a basic arm, and a balancing structure, which can meet the requirements of a maximum angle of 68 degrees between the basic arm and the horizontal, and a maximum angle of 134 degrees between the upper folding arm and the basic arm. The slewing structure consists of a turntable, a cycloidal motor, a worm gear reducer, etc., which can achieve a 360-degree rotation. The center swivel joint is a hydraulic component used to transmit pressure oil to ensure the smooth flow of oil and circuits.

[0004] The control panel of the mobile small aerial work vehicle can control the circuit board through buttons, transmit the circuit board signal to the signal receiver, and then transmit it out by the signal receiver. Such a control system can ensure that the staff can control various actions of the equipment through buttons and improve work efficiency.

[0005] When controlling the aerial work vehicle, the existing remote control system inputs control signals through buttons to move the work vehicle to a certain working position, and then performs aerial work. However, the existing control panel is not equipped with an anti-accidental touch cover. When the staff accidentally touches the button or joystick while working, it may cause the work vehicle to shake, which is dangerous.

[0006] Therefore, it is necessary to provide a kind of movable small aerial work vehicle remote control system to solve the above-mentioned technical problems. Utility Model Content
