Elevator guide rail installation calibration device and methodTechnical Field
The invention relates to an elevator guide rail installation calibration device and method, and belongs to the technical field of elevator installation.
Background
Along with the acceleration of the urban process, the construction of high-rise and super-high-rise buildings in China is brought into new development opportunities, and the urban high-rise building has become a main matrix for the construction of global high-rise buildings. Such buildings represent not only the astronomical lines of cities, but also place higher demands on the internal vertical traffic system, especially the wide application of high-speed elevators is a necessary trend. As a key device connecting floors, a high-speed elevator has its carrying efficiency and passenger riding experience directly related to the overall operating efficiency and comfort of the building.
In elevator systems for high-rise and super-high-rise buildings, the installation accuracy of the elevator guide rails, which serve as key components for supporting and guiding the elevator car to move up and down, directly affects the stability, safety and passenger comfort of the elevator operation. Due to the high demands of high-rise and super-high-rise buildings on the elevator carrying speed, the elevator guide rails need to bear not only higher running speeds and larger dynamic loads, but also extremely low vibration and noise levels during high-speed running, which presents extremely severe challenges for the installation accuracy of the guide rails.
However, there are several problems to be solved in the current elevator guide rail installation process:
1. The labor intensity challenge brought by the material and the weight increase of the guide rail is that the guide rail adopted by the high-speed elevator has higher weight and rigidity, and the weight and the rigidity are increased by 5 to 10 percent compared with the common guide rail of the high-rise building elevator. The change obviously increases the labor intensity of installation operators, and has higher requirements on the physical strength, skill and operation efficiency of the installation operators.
2. The installation period is long, the time consumption for calibration and adjustment is high, the calibration and adjustment after the installation of the guide rail is one of the longest links in the elevator installation process of high-rise and super-high-rise buildings, the calibration and adjustment accounts for about 20% of the construction time of the whole elevator engineering, and the proportion can further rise along with the increase of the building height. This not only prolongs the construction period, increases project costs, but also affects the overall delivery schedule of the building.
3. The manual installation and calibration precision is insufficient, the traditional manual installation and calibration mode is limited by the skill level, physical condition and environmental factors of operators, and the extremely high precision requirement required by the operation of the high-speed elevator is difficult to achieve. Insufficient precision can lead to vibration, noise increase in the elevator operation process, and then influences passenger's comfort level of taking, probably threatens the safe operation of elevator even.
In addition, even though the existing elevator guide rail installation calibration device can alleviate the problems existing in the elevator guide rail installation process to a certain extent, the existing elevator guide rail installation calibration device is of a hard connection structure and adopts a mode of hard clamping the elevator guide rail. When the elevator guide rail is clamped, the problem of stress concentration caused by self clamping of the structure can be solved, the structure of the calibration device can deform due to the reasons of the structure, assembly, stress and the like, the torque generated when the elevator guide rail is clamped in a self-adaptive manner can be reduced, the stability of the assembly of the calibration device can be reduced, the parallelism requirement of guide rail calibration can not be met, and the calibration precision is low.

S4, removing the guide rail measuring mechanism 3, lifting the construction platform to a proper position, continuously installing a second group of elevator guide rails 8, loosening bolts of a guide rail bracket after installing a calibration device on the elevator guide rails, loosening the elevator guide rails 8, installing the guide rail measuring mechanism 3, measuring numerical values in the X axis and Y axis directions, comparing the numerical values with the numerical values recorded in the step S3, automatically calibrating the elevator guide rails 8, and fixing the guide rail bracket bolts again after ensuring that the numerical values are within a tolerance range (meeting the requirements), so that the elevator guide rails 8 are fixed;
S5, repeating the step S4 until the last group of guide rails are installed.
