Description

Technical Field

[0001] The utility model relates to the technical field of spray painting of counterweight blocks, in particular to a spray painting tool for processing elevator counterweight blocks. Background Art

[0002] An elevator is a permanent transportation device that serves several specific floors in a building. Its car runs on at least two rows of rigid tracks that are perpendicular to the horizontal plane or have an inclination angle of less than 15° to the plumb line. There are also stepped types, with treads mounted on tracks and running continuously, commonly known as escalators or moving walkways. The size and structure of the car are convenient for passengers to enter and exit or load and unload goods. It is customary to use elevators as a general term for vertical transportation vehicles in buildings, regardless of their driving mode.

[0003] The main function of the elevator counterweight is to control the balance and operation of the elevator, ensure that the elevator can stop smoothly when going up and down, and improve the operation efficiency and safety of the elevator. It balances the weight of the elevator itself and the weight of the passengers through the relative weight, so that the elevator always maintains a balanced state during operation. Specifically, the elevator counterweight can balance the gravity and traction that the elevator bears during operation, ensuring that the gravity and traction of the elevator are balanced when it is on different floors, thereby ensuring the smooth operation of the elevator.

[0004] During the processing of the counterweight, a protective paint layer needs to be coated on its surface by a paint spraying device to improve the aesthetics and corrosion resistance of the counterweight. However, when painting the upper and lower surfaces of the counterweight, the counterweight needs to be turned over. In the existing turning mechanism, the position of the counterweight is easily changed after turning over the counterweight, resulting in the need to readjust the position when painting the other side of the counterweight, or to add a new set of paint spraying equipment, which increases the equipment cost and reduces the quality of the paint. Therefore, those skilled in the art provide a paint spraying tool for elevator counterweight processing to solve the problems raised in the above background technology. Utility Model Content
