Electromagnetic guide shoe and elevator guiding system using same

Abstract

The invention discloses an electromagnetic guide shoe. The electromagnetic guide shoe comprises a base, wherein the base is T-shaped, and comprises a body and a convex part which are integrally formed, clamping grooves are symmetrically formed in the two sides, opposite to the convex part, of the body, the ends, far away from the convex part, of the clamping grooves are fixedly provided with electromagnets in a clamped mode, and the other end, close to the convex part, of the clamping grooves are provided with brake blocks made of magnetic materials in a sliding and clamping mode, and the electromagnets and the brake blocks are fixedly connected through at least one compression spring. The invention further discloses an elevator guiding system. According to the electromagnetic guide shoe and the elevator guiding system, non-contact guiding can be achieved between the electromagnetic guide shoe and guide rails, so that the maintenance cost is low, the noise is low, and the safety is high; and meanwhile, a braking function is also achieved, overspeed of upward and downward travelling of an elevator is prevented, a traditional safety clamp device is replaced, and then the cost is saved.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an electromagnetic guide shoe and an elevator guide system using the electromagnetic guide shoe. Background technique [0002] At present, most of the guide shoes used in elevators are sliding guide shoes or roller guide shoes. The guide shoes are in direct contact with the T-shaped guide rail. After a period of use, the guide shoes will wear out, causing system noise and elevator vibration. Therefore, the guide shoes need to be regularly checked. Maintenance and replacement costs are high. In recent years, some manufacturers have adopted electromagnetic guide shoes to replace traditional sliding guide shoes or roller guide shoes. The electromagnetic guide shoes do not directly contact the T-shaped guide rails, avoiding friction with the T-shaped guide rails, and the elevator runs more smoothly. However, when the existing electromagnetic guide shoes are used, it is necessary t...

AI Technical Summary

Problems solved by technology

However, when the existing electromagnetic guide shoes are used, it is necessary to install an electromagnet in the T-shaped guide rail or the T-shaped guide rail itself uses a magnetically conductive material, which is realized by energizing the T-shaped guide rail to generate an induced magnetic field. The actual operation is difficult and it is easy to cause electric shock. accident, low safety
