Wide-range height-adjustable hydraulic lifting device and control method thereof

Abstract

The invention provides a wide-range height-adjustable hydraulic lifting device comprising a supporting mechanism, a moving mechanism, an oil way system and a lifting height measuring device. The moving mechanism and the measuring device are both installed on the supporting mechanism. The oil way system is connected with the supporting mechanism. The supporting mechanism is a main body structure of the hydraulic lifting device and is used for installing the moving mechanism, the oil way system and the measuring device. The moving mechanism is used for transferring the lifting device, and the moving mechanism is divided into two parts which are fixed to the supporting mechanism and the oil way system correspondingly. The oil way system is used for storing and conveying hydraulic oil and installed on the supporting mechanism. The measuring device is used for visualizing the position of the lifting device, and measuring and calibrating devices of the measuring device are installed on the supporting mechanism and the oil way system correspondingly. According to the hydraulic lifting device, the movement direction of an oil cylinder can be changed through a hand-operated direction change valve, and the lifting stroke is large and can be adjusted at any time according to use conditions. Meanwhile, lifting of the device is achieved through a hand pump, no electrical requirement is needed for workplaces, and the wide-range height-adjustable hydraulic lifting device can be suitable for various workplaces.

Description

technical field [0001] The invention relates to the technical field of lifting devices, in particular to a wide-range height-adjustable hydraulic lifting device and a method for using the same. Background technique [0002] When transferring some heavy equipment, it is often necessary to lift the equipment. In this process, not only the lifting process of the equipment is required, but also the lowering process of the equipment must be controllable to avoid excessive impact when the heavy equipment falls by its own gravity , causing damage to the equipment itself or the lifting device. When traditional heavy equipment is lifted, large-scale automatic hoisting equipment is usually used, such as cranes or cranes, but in many workplaces, large-scale hoisting equipment cannot be entered or installed, and the electrical conditions of some workplaces cannot meet the needs of automatic hoisting equipment; at the same time, traditional portable lifting equipment The equipment strok...

Problems solved by technology

When traditional heavy equipment is lifted, large-scale automatic hoisting equipment is usually used, such as cranes or cranes, but in many workplaces, large-scale hoisting equipment cannot be entered or installed, and the electrical conditions of some workplaces cannot meet the needs of automatic hoisting equipment; at the same time, traditional portable lifting equipment The equipment stroke and carrying capacity are small, and it is impossible to complete the long-stroke lifting operation of heavy equipment

[0003] In order to solve the problem of lifting heavy equipment in places with limited working conditions, the present invention provides a wide range of height-adjustable manually operated hydraulic lifting device to meet the lifting requirements of heavy equipment of various sizes in multiple occasions
