Construction elevator guide rail safety warning and control device

Abstract

The invention provides a safety early warning and control device for the guide rail frame of the construction elevator. It is provided with a bumper on the drive plate of the transmission trolley of the construction elevator, and an early warning and control mechanism on the top surface of the cage. The push rod of the early warning and control mechanism is connected with the The touch bars are in contact, and the drive plate of the transmission trolley moves up and down along the guide rail frame of the construction elevator. When the drive plate of the transmission trolley climbs to the standard section of the guide rail frame where the tilt or deformation exceeds the limit, the touch rod on the drive plate of the transmission trolley pushes the push rod to generate Displacement, so as to start the early warning and control mechanism, and issue a safety hazard alarm. After the alarm, when the cage continues to climb, the control mechanism will automatically forcibly cut off the power supply of the drive motor, so as to prevent the continuation of personnel violations and prevent the potential safety hazards of the equipment from being released to the public. Aspects of expansion, so as to avoid the occurrence of security incidents.

Description

Technical field: [0001] The invention belongs to the technical field of construction elevator safety, and in particular relates to a safety early warning and control device for a construction elevator guide rail frame. Background technique: [0002] With the continuous expansion of the scale of my country's capital construction, the degree of mechanization of building construction is increasing day by day, and the construction technology has changed rapidly. Vertical transportation equipment, especially construction elevators (also known as construction elevators) have been widely used in building construction. usage of. As a convenient and quick vertical transportation machine for people and goods, construction elevators are widely used in various high-rise building constructions, and are favored by many construction companies. However, it is also a very dangerous construction machine. In recent years, vicious accidents of construction elevators have occurred from time to...

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
