Abstract

The invention discloses a hydraulic free lifting device, comprising a main body box, the outer end of the main body box is provided with a support seat, and the support seat is fixedly connected in the main body box, and the outer surface of the main body box is provided with a power distribution box. box, and the distribution box is fixedly connected in the main box, and the outer surface of the distribution box is provided with a transmission tube, and the transmission tube is embedded in the distribution box. This kind of hydraulic free lifting device has a simple structure. It is easy to operate, equipped with a hydraulic pump station, and there is an overflow valve in the hydraulic pump station, and the hydraulic pump station is connected to the handle. This structure is conducive to the emergency descent of the machine when the power is cut off. The descent can be manually controlled by the handle, which greatly improves the original It has the function that the machine cannot be emergency when the power is cut off, which reduces the failure rate. Because there is an overflow valve inside, it can prevent the system from being too pressured when it is running upwards, and it plays the role of overload protection.

Description

technical field [0001] The invention relates to the technical field of lifting devices, in particular to a hydraulic free lifting device. Background technique [0002] The hydraulic lift mainly realizes the function of lifting through the pressure transmission of hydraulic oil. Its scissor mechanical structure makes the lift have high stability in lifting, and the wide operating platform and high carrying capacity make the range of high-altitude operations wider Large and suitable for multiple people to work at the same time, it makes high-altitude work more efficient and safer. [0003] However, the hydraulic pump station provided with the existing hydraulic free lifting device has no overflow valve and no handle, so the machine cannot be lowered in an emergency when the power is cut off, and the emergency effect cannot be achieved. As a result, the object will fall. At the same time, the original structure is relatively complicated, the hydraulic effect is not strong, and...
