Description
Technical Field
The invention belongs to the technical field of elevator guide rail installation, relates to an elevator guide rail installation adjusting device, and particularly relates to a rigid and flexible wall supporting mechanism for an elevator hoistway.
Background
With the rapid development of economy, high-rise buildings and super high-rise buildings are transported like bamboo shoots in spring after rain, and elevators in the high-rise buildings become an indispensable part of people's lives. The installation of the elevator guide rail plays an important role in the normal operation of the elevator, and whether the elevator can run stably at high speed depends on whether the installation of the elevator guide rail is accurate and reliable. In the elevator hoistway, the working environment is sultry, not ventilated and dusty, and the working environment of elevator guide rail installation workers is extremely severe. Currently, in the field of elevator installation, installers are extremely scarce, and automated installation and adjustment of elevator guide rails is becoming a future trend. The design of the elevator shaft wall supporting mechanism and the assembly of the manipulator on the wall supporting mechanism to realize the automatic installation and accurate adjustment of the elevator guide rail are very important.
Patent of invention device and method for calibrating guide rails in an elevator shaft (CN105398911B) proposes a device and method for calibrating guide rails in an elevator shaft, comprising a positioning unit and a calibration unit. A first attachment device is provided on the positioning unit, which is freely movable at each end of the positioning unit and supported in the elevator shaft on the opposite wall structure. The calibration unit is provided with a second attachment device, which is also freely movable at each end of the transfer unit, enabling elevator guide rail vertical calibration. However, the device has the problem of poor overall centering performance of the system, due to the fact that the device adopts a two-point supporting mode, the surface of the wall body of the elevator shaft is uneven, two supporting points of a supporting component of a supporting wall structure cannot be guaranteed to be in close contact with the wall body of the elevator shaft at the same time, and therefore the initial horizontal pose and vertical pose states of the calibration unit are affected, the initial calibration standard set by the calibration unit has certain deviation with the true value, and finally large errors occur in installation and calibration of the elevator guide rail.
The invention patent of an intelligent elevator installation system (publication number CN112520534A) discloses an intelligent elevator installation system, which comprises a guide rail installation device moving along an elevator shaft from top to bottom and installing an elevator guide rail, and a material conveying device supplying the elevator guide rail to the guide rail installation device upwards. The material conveying device also comprises a clamping component for clamping the elevator guide rail, a horizontal lifting device for driving the clamping component to move horizontally and lift, and a conveying component for conveying the elevator guide rail. The elevator guide rail is conveyed to the elevator guide rail mounting device through the guide rail material conveying device, and then the guide rail is automatically mounted in the elevator shaft, so that the automatic laying of the elevator guide rail is realized. The invention focuses on the method of automatic installation of elevator guide rails, but there is less work to describe the calibration of the device before installation of the elevator guide rails. The important factor of elevator guide rail installation is to ensure the vertical installation of the guide rail, and the calibration of the horizontal pose and the vertical pose of the device before installation is a vital preparation. The installation accuracy of the elevator intelligent installation system is low because of the lack of a calibration structure.
