Safety warning and control device for construction hoist guide rail frame

Abstract

The invention provides a safety warning and control device for a construction hoist guide rail frame. A bump rod is arranged on a driving plate of a transmission trolley of a construction hoist; a warning and control mechanism is arranged at the top of a cage; a push rod of the warning and control mechanism is in contact with the bump rod; the driving plate of the transmission trolley vertically moves along the guide rail frame of the construction hoist. When the driving plate of the transmission trolley climbs to a standard guide rail frame section with transfinite incline or deformation, the bump rod on the driving plate of the transmission trolley pushes the push rod to generate displacement, then the warning and control mechanism is started and gives out a potential risk alarm, the cage continuous climbing after warning, the control mechanism automatically disconnects a power source of a transmission motor forcefully, people acts in violation of regulations are eradicated, equipment potential risks are eradicated from extending to a higher level, and security incidents are avoided.

Description

[0001] Technical field: [0002] The invention is a safety technology field of construction lift, which involves a safety warning and control device of a construction elevator rail. Background technique: [0003] With the continuous expansion of my country's basic construction scale and the increasing mechanization of construction construction, the construction technology has changed rapidly, and vertical transportation equipment, especially the construction elevator (also known as the construction elevator for construction) in construction construction in construction construction. usage of.As a convenient and fast -moving vertical transportation machinery, the construction lift machine is widely used in various high -rise buildings, and is favored by many construction enterprises.However, it is also a very dangerous construction machinery. In recent years, the vicious accident of construction lifts has occurred. The root cause is that the management measures are not in place....

AI Technical Summary

Problems solved by technology

However, due to the low cost, simple structure, and poor operation process, the construction elevators for construction are often exposed to the outside, and most construction elevators for construction are temporarily leased, and they often need to be changed in height and frequently assembled and disassembled during use. During the process of dismantling, assembling, hoisting and transportation of the standard section, often due to unsafe behaviors of people, there are false fixes and missing connecting bolts in the connection between the standard section and the standard section, thus giving rise to the elevator guide rail frame. Safety lays a hidden danger of accidents

With the frequent up and down movement of the elevator cage, and the lack of personnel inspection, and because the false fixed standard joints do not reach the pre-tightening force of the bolts, it is difficult to see the loosening of the bolts under the condition of no force, etc. Over time, the safety of the elevator guide rail frame will become worse and worse, which means that elevator safety accidents may occur at any time
