Description
Technical Field
[0001] The utility model relates to the technical field of elevator guide rail calibration devices, in particular to an elevator guide rail automatic calibration and adjustment device. Background Art
[0002] With the acceleration of urbanization, there are more and more high-rise buildings. As an important vertical transportation tool, the safety and stability of elevators are of vital importance. As the main supporting structure for the operation of elevators, the installation accuracy and calibration adjustment of elevator guide rails are of great significance to the safe operation of elevators. When calibrating elevator guide rails, the traditional operation method is generally to manually use corresponding tools for calibration and adjustment operations. However, manual operation is difficult and consumes more time and manpower. In order to improve efficiency and save manpower, automatic calibration and adjustment devices are usually used for calibration and adjustment operations.
[0003] The utility model patent with authorization announcement number CN216918203U discloses an automatic calibration device for elevator guide rails, including a detection device and an execution device; the detection device includes an X-axis detection mechanism arranged on the elevator guide rail for detecting the deviation between the elevator guide rail and the plumb line in the X-axis direction, a Y-axis detection mechanism for detecting the deviation between the elevator guide rail and the plumb line in the Y-axis direction, and a parallelism detection mechanism for detecting the angular deviation between two relatively arranged elevator guide rails; the execution device includes a base directly or indirectly fixed on the side wall of the hoistway and an X-axis adjustment mechanism arranged on the base for adjusting the position of the elevator guide rail in the X-axis direction, a Y-axis adjustment mechanism for adjusting the position of the elevator guide rail in the Y-axis direction, and a parallelism adjustment mechanism for adjusting the parallelism of the two relatively arranged elevator guide rails and the direction of the elevator guide rails; through the above improvements, the automatic calibration device for elevator guide rails of the utility model is more portable and more flexible and convenient to use.
[0004] Although this technical solution has the advantages of being lighter and more flexible and convenient to use, when it is used in practice, the frame on it is pressed against the inner wall of the elevator shaft by the movement of the telescopic cylinder to achieve fixed operation. However, when the telescopic cylinder is used, the corresponding air source or hydraulic source component is required to control the telescopic operation. The volume of the air source or hydraulic source is relatively large. Due to the small space in the elevator shaft, it is difficult to carry the air source or hydraulic source into the elevator shaft for operation. If the pipeline is laid out, the placement of the pipeline will also affect the normal detection operation, making the support and fixing operation more troublesome and causing inconvenience to the staff. In view of this, we propose an automatic calibration and adjustment device for elevator guide rails. Utility Model Content
