Elevator for construction elevator shaft and construction scheme

Abstract

The invention discloses an elevator for a construction elevator shaft. The elevator for the construction elevator shaft comprises a wall-attached guide rail frame, a vertical monitoring device, an intelligent door opening device, an emergency anti-falling device, a guide rail mounting frame, a cage operation device and a safety device. The wall-attached guide rail frame comprises cylindrical guide rails, a wall-attached frame body, fixing lug plates, inclined pull rods, inclined rod connecting sleeves, fixing bolts, high-strength bolts, rod piece protruding heads, rod piece grooves, transmission racks, a height limiting baffle, limiting frame bodies and a base and is fixed to a concrete wall in the construction elevator shaft. The cylindrical guide rails with a cylindrical shape are arranged on the front side face of the wall-attached guide rail frame, the wall-attached frame body with a square tube shape is arranged on the back side face of the wall-attached guide rail frame, and the wall-attached frame body and the concrete wall body are fixed in a leaning mode. According to the elevator for the construction elevator shaft, the high-strength bolts are adopted for vertical connection and are connected with the concrete wall body in the elevator shaft, stable reliability of the elevator in operation can be ensured, and the safety problems that an outdoor elevator is large in wind load, poor in stability and high in risk are solved.

Description

technical field [0001] The invention relates to the field of elevators, in particular to elevators and construction schemes for construction of elevator shafts. Background technique [0002] At present, construction elevators are widely used in construction sites. Since they are installed outdoors at the connection position with the wall, the elevator is greatly affected by the wind during its upward operation. The higher the installation, the greater the wind resistance, the worse the operation stability, and the lower the safety factor; Because the existing elevator has an elevator cage on the left and right sides of the guide rail frame, the lateral tension and vibration of the elevator cage during operation often lead to the loosening of the connecting bolts of the guide rail frame, which in turn leads to the breakage of the bolts and the collapse of the elevator. ;Because the installation and maintenance of the elevator is performed at a high place, there is a lack of r...

Problems solved by technology

[0002] At present, construction elevators are widely used in construction sites. Since they are installed outdoors at the connection position with the wall, the elevator is greatly affected by the wind during its upward operation. The higher the installation, the greater the wind resistance, the worse the operation stability, and the lower the safety factor; Because the existing elevator has an elevator cage on the left and right sides of the guide rail frame, the lateral tension and vibration of the elevator cage during operation often lead to the loosening of the connecting bolts of the guide rail frame, which in turn leads to the breakage of the bolts and the collapse of the elevator. ;Because the installation and maintenance of the elevator is performed at a high place, there is a lack of reliable protective measures around it, which is difficult and risky; due to insufficient maintenance, the connection bolts of the elevator are loosened or broken from time to time, resulting in frequent accidents of elevator collapse , Elevator collapse casualties have become an increasing trend year by year
