Self-sensing repair type ball guide shoe for elevator

Abstract

The invention discloses a self-sensing repair type ball guide shoe for an elevator, and belongs to the technical field of elevators. The self-sensing repair type ball guide shoe for the elevator greatly reduces the friction coefficient of the elevator guide shoe and a guide rail during operation, ensure the stability and safety in the operation process of the elevator and can autonomously sense the abrasion of composite high-abrasion-resistance balls in the operation process. Once the abrasion loss reaches a design value, the composite high-abrasion-resistance balls are repaired in a targetedmode through a repairing rod arranged in a repairing ball seat, and fixed-point accurate repairing is conducted based on the magnetic attraction effect. Repairing microspheres are released to a worn area to actively repair the matched composite high-wear-resistance balls, and the worn area of the composite high-wear-resistance balls is supplemented, so that normal high-precision guidance is restored. Therefore, the elevator guide shoe has the advantages of long service life and long maintenance period, regular independent maintenance work by technicians is approximately avoided, and only supplementing of the repairing microspheres during overall maintenance of the elevator is needed.

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
