Introduction to elevator guide shoes

The sliding guide shoe is a nylon block that can slide between the elevator guide rail and the car, called a guide shoe. It can fix the car on the guide rail, allowing the car to only move up and down. There is also an oil cup on the upper part of the guide shoe to reduce the friction between the shoe lining and the guide rail.

Definition of sliding guide shoes

Each elevator car is equipped with four sets of guide shoes, which are respectively installed on both sides of the upper beam and under the safety clamp seats at the bottom of the car. Four sets of counterweight guide shoes are installed at the bottom and top of the counterweight beam.

The guide shoes fixed on the car can move up and down back and forth along the fixed guide rails installed on the wall of the building's shaft, preventing the car from tilting or swinging during operation.

Sliding guide shoe structure

The sliding guide shoe is composed of the guide shoe head, guide shoe body, guide shoe seat, etc.

Installation of the sliding guide shoe

The installation method of the sliding guide shoe is to place it at the installation position of the car frame guide rail. After aligning the position, it is fixed to the car guide rail frame with bolts. The installation of sliding guide shoes must meet the following requirements:

1. After the upper and lower guide shoes are installed in place, they should be on the same vertical line without any skewing or twisting. Ensure that the upper and lower guide shoes are in a straight line with the center of the safety clamp. Roller type guide shoe fixed guide shoe

2 Fixed guide shoes are mainly used in freight elevators. The gaps on both sides should be consistent, and the gap between the inner lining and the top surface of the track should be 0.5 to 2mm.

Types of sliding guide boots

Elevator guide shoes are divided into rolling guide shoes and sliding guide shoes!

1. Rolling guide shoes, which are clamped onto the track with three or six wheels, are generally used in elevators with a speed of over 2 meters!

Features: It replaces sliding friction with rolling friction, reducing friction loss, minimizing vibration and noise during operation, and enhancing the comfort of riding. However, the processing and installation requirements for this type of guide shoe are relatively high.

2. The fixed sliding guide shoe is a sliding groove clamped on the guide rail (that is, a concave groove), which is generally used in elevators with a speed of less than 2 meters!

Features: As the guide shoe head is fixed and the structure is simple without an adjusting mechanism, as the running time of the elevator increases, the fit clearance between the guide shoe and the guide rail will become larger and larger, causing the car to shake during operation and even experience impact.

3. Elastic sliding guide shoes are further classified into spring-type sliding guide shoes (suitable for elevators with a rated speed of less than 1.7M/S) and rubber spring-type sliding guide shoes (suitable for medium and high-speed elevators).
