Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to an automatic calibration 100-meter laser plumb line system for an elevator shaft. Background Art

[0002] During the installation of the elevator, the installation of the elevator guide rails and landing door components is an important part of the elevator installation, and the installation quality directly affects the comfort and safety of the elevator operation. During the installation of the elevator, the elevator guide rails and landing door components need to be fixed vertically along the elevator shaft, and all the shaft components in the same vertical linear direction need to be installed on the same straight line to ensure that there will be no shaking or abnormal noise during the operation of the elevator. Therefore, it is necessary to calibrate the installation position of the elevator shaft components.

[0003] The existing elevator installation calibration technology generally calibrates the elevator guide rails by placing sample lines in the elevator shaft. The sample lines are usually thin steel wires, which are easily affected by the airflow in the elevator shaft, resulting in poor layout accuracy. Due to the poor layout accuracy, the installation error of the shaft components is large, affecting the safety of elevator operation. Utility Model Content

[0006] The first substrate is installed on the top of the shaft to carry the laser automatic adjustment transmitter and the plumb bob reeling device. The laser point receiving positioning disk is installed at the bottom of the shaft to receive the laser beam emitted by the laser automatic adjustment transmitter or the laser plumb bob. A winch rope is wound around the take-up disk. The winch rope is a 100-meter nylon line. The winch rope passes through the small hole on the adjustment block so that the winch rope is located below the center point of the laser automatic adjustment transmitter. A laser plumb bob is installed at the lower end of the winch rope. The position of the first substrate in the X-axis and Y-axis directions is adjusted through the adjustment component, so that the laser beam emitted by the laser plumb bob is at the approximate center position of the laser point receiving positioning disk. The laser point receiving positioning disk measures the position coordinates of the vertical point and calibrates it.

[0007] Then remove the laser plumb bob, wind up the winch rope through the take-up drum, adjust the position of the adjustment block to avoid the center point below the laser automatic adjustment transmitter; connect the laser emitting lamp to the power supply, emit a laser beam that falls on the laser point receiving positioning disk and is compared with the vertical point coordinates of the laser plumb bob.
