Problems solved by technology

[0003] In order to ensure the stability of the product, protect the life safety of the staff, and prevent the braking distance from being too long, it is required to shorten the braking distance as much as possible. However, the existing lifting platform has a long braking distance and low safety; if the brake is increased The braking torque shortens the braking distance, and the lifting platform will produce a greater impact, reducing stability and comfort

Abstract

The invention discloses a hydraulic driving system of a lifting platform. The hydraulic driving system comprises a brake, a motor and a damping reversing device, wherein the motor is communicated with an oil pump and an oil tank by virtue of the damping reversing device, the flow direction of hydraulic oil in the motor can be controlled by the damping reversing device, and the flow of the hydraulic oil in the motor is blocked after the oil supply is stopped. When braking is needed, the brake is operated, the oil supply to the motor is stopped, so that the flow of the hydraulic oil in the motor is blocked, the oil return backpressure of the motor is increased, the speed of the motor is reduced, and the brake is matched, so that the braking distance can be shortened, and the stability and comfort are increased. The invention further discloses the lifting platform, which comprises the hydraulic driving system.

Description

technical field [0001] The invention relates to the field of lifting platforms, in particular to a hydraulic drive system for lifting platforms. In addition, the present invention also relates to a lifting platform comprising the above-mentioned hydraulic drive system. Background technique [0002] Lifting platforms are widely used in many fields, generally including chassis, working platform and hydraulic drive system. By driving the motor to rotate, the whole vehicle is then driven forward. At present, the purpose of vehicle braking is achieved through the brake, and the purpose of stopping the vehicle is achieved by pressing the friction plate with the spring. In the existing hydraulic drive system, the brake is controlled by hydraulic oil. When there is pressure oil in the oil inlet of the brake, the brake is released and the vehicle can walk. When the supply of pressure oil is stopped, the brake relies on its own spring to start the vehicle. brake. [0003] In order ...
