The elevator needs the cooperation of various accessories to make the elevator operate normally. The elevator guide wheel is one of the most important equipment in elevator accessories. Then China Bed Elevator Supplier will introduce its function
The main function of the guide wheel is to limit the freedom of the car and the counterweight, so that the car and the counterweight can only move up and down along the guide wheel. The main purpose is to increase the distance between the car and the counterweight and change the direction of movement of the wire rope.
The elevator guide wheel has a pulley structure, and its role is to save the effort of the pulley block. When installing the guide wheels, first hang a plumb line on the floor of the machine room or on the load-bearing beam to align with the center point of the counterweight on the sample frame. On both sides of this vertical line, with the width of the guide wheel as the interval, hang two auxiliary vertical lines respectively, and use these three lines as the reference to install and correct the traction wheel.
1. Alignment of the parallelism of the guide wheels: The alignment of the parallelism of the guide wheels means that the connection line between the vehicle center point on the traction wheel and the counterweight center point on the guide wheel is perpendicular to the supporting beam, traction wheel, and guide wheel. The reference line coincides with the two sides of the guide wheel and should be parallel to the reference line.
2. Correction of the verticality of the guide wheel: The verticality of the guide wheel is exactly that the two sides of the guide wheel should be parallel to the vertical line.
3. Technical requirements for the installation of the guide wheel: the vertical error of the guide wheel should be no more than 2.0mm; the parallelism error between the end face of the guide wheel and the end face of the traction wheel should be no more than 1mm.
