Freight elevator guide shoe

The guide shoe is a sliding nylon block between the elevator guide rail and the cage, called the guide shoe. It can fix the cage on the guide rail, so that the cage can only move up and down. The upper part of the guide shoe also has an oil cup, reducing the friction between the shoe liner and the guide rail.

Each elevator cage is equipped with four sets of guide boots, which are respectively installed on both sides of the upper beam and under the safety clamp seat at the bottom of the cage; Four pairs of heavy guide boots are installed at the bottom and top of the heavy beam.

The guide boots fixed on the cage can move up and down along the fixed guide rails installed on the wall of the building shaft to prevent the cage from slanting or swinging in operation.

Guide boots consist of guide boots head, guide boots body, guide boots seat, etc.

Guide shoe installation method is on the install a 臵 capsules frame rail, seek after orthotopic 臵, bolted in capsules guide frame. The installation of guide boots must meet the following requirements:

1. After the upper and lower guide boots are installed in place, they should be on the same vertical line, no skew or deflection is allowed, and ensure that the upper and lower guide boots are aligned with the center of the safety clamp mouth at three points. Roller type guide shoe fixed guide shoe

2. Fixed guide boots are mainly used for cargo ladder. Clearance on both sides should be the same. Clearance between lining and top surface of track should be O. 5 ~ 2 mm.

Elevator guide boots rolling guide boots and sliding guide boots!

1 rolling guide boots are 3 or 6 wheels stuck in the track is generally used for the speed of the elevator in more than 2 meters!

Features: rolling friction replaces sliding friction, reduces friction loss, reduces vibration and noise in operation, and improves ride comfort, but this kind of guide shoe processing and installation requirements are relatively high.

2. Fixed sliding guide boots is a slideway stuck on the guide rail "is concave groove" is generally used for the speed of the elevator below 2 meters!

Features: as the guide shoe head is fixed and has a simple structure and no adjusting mechanism, as the operation time of the elevator increases, the gap between the guide shoe and the guide rail will become larger and larger, and the cage will shake or even impact during the operation.

3. Elastic sliding guide boots are divided into spring type sliding guide boots (applicable to elevators with rated speed less than 1.7m /S) and rubber spring type sliding guide boots (applicable to medium-high speed elevators).
