A self-sensing and repairing ball guide shoe for elevators

Abstract

The invention discloses a self-sensing and repairing ball guide shoe for elevators, which belongs to the technical field of elevators. It is a self-sensing and repairing ball guide shoe for elevators, which can greatly reduce the friction coefficient between the elevator guide shoe and the guide rail during operation, and ensure The stability and safety of the elevator during operation, and the wear of the composite high wear-resistant ball can be independently sensed during operation. Once the wear reaches the design value, it can be repaired by repairing the repair rod set in the ball seat. Carry out precise fixed-point repair based on magnetic attraction, release repair microspheres to the worn area to actively repair the matching composite high-wear-resistant balls, supplement the wear of the composite high-wear-resistant balls to restore normal high-precision guidance, and make elevator guide shoes It has the advantages of long service life and long maintenance cycle, which almost eliminates the regular independent maintenance work of technicians, and only needs to supplement and repair the microspheres for the overall maintenance of the elevator.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a self-sensing and repairing ball guide shoe for elevators. Background technique [0002] As an important means of transportation for transporting people and goods in the vertical direction, elevators have been fully integrated into our lives and are closely related to our daily life. With the rapid development of social economy, everyone is concerned about the safety and comfort of elevator operation. More and more stringent requirements are put forward in aspects such as performance and rapidity. [0003] The elevator is mainly composed of a car system, traction system, guidance system and control system. The car system is used to load passengers or goods, the traction system is used to provide power to the car, the guidance system is used to guide the operation of the car, and the control system It is used to control the whole system of the elevator. The guidance system is ...

Problems solved by technology

[0005] However, the wear of the ball is inevitable under long-term high-load and pressure work. Once the amount of wear accumulates to a certain extent, the guiding accuracy between the guide shoe and the guide rail will be greatly reduced, and the elevator car will shake when it is raised and lowered. Certainly dangerous, since the actual amount of wear cannot be known by technicians at any time, it is still necessary to regularly detect and maintain the wear of the balls, which requires a lot of manpower and material costs, and also affects the normal use of the elevator
