Improvement method for hydraulic lifter for building and reel structure

Abstract

The invention discloses an improvement method for a hydraulic lifter for a building. According to the method, a hydraulic oil path and a hydraulic element are used as a control system; a motor drives an oil pump as a power source of the system; a travel switch is used as a positioning element for realizing precise positioning of the position of a hanging basket. In order to realize automatic operation requirements, a PLC (programmable logic controller) is adopted as a control element of an electrical appliance device, so that automatic control on the system is realized; in order to increase the system safety, an anti-dropping device is additionally arranged the tail end of a steel wire rope, so that the system reliability is reinforced; the brake part of the device is completed by dragging a belt type brake by a brake oil cylinder. The improvement method is simple in principle, convenient in operation, high in precision and reliability and capable of greatly reducing equipment fault risk.

Description

technical field [0001] The invention relates to the field of construction equipment. , especially an improved method and reel structure of a hydraulic lift for construction. Background technique [0002] Since the 1970s, with the continuous increase of high-rise and super high-rise buildings, construction elevators have been widely used in order to efficiently transport construction materials, equipment and operators. With the rapid development of science and technology, the field of construction elevators has been continuously introduced, making the technology of construction elevators more and more mature. Serialized and composite new models continue to emerge, showing strong vitality. Construction elevators are not only used in urban high-rise and super high-rise buildings, but also with the increase in building height, the demand for construction elevators with a height greater than 200m is also increasing. [0003] There are many manufacturers of construction elevator...

AI Technical Summary

Problems solved by technology

However, in the process of building construction, because the construction floors are generally high, it is often necessary to transport various materials, such as bricks, sand, stones, cement, steel bars and various equipment, etc., but these materials are generally transported by elevators to self-built buildings. Then a large amount of labor is required to move to the corresponding place in the building, which not only brings safety hazards to our staff, but also takes time and effort, reducing work efficiency
