Elevator rolling wheel guide shoe

Abstract

The invention provides an elevator rolling wheel guide shoe installed on an elevator guide rail. The elevator rolling wheel guide shoe comprises a shoe seat connected with an elevator car and a pair of buffering rolling wheel devices symmetrically installed on the shoe seat. Each buffering rolling wheel device comprises an L-shaped support, a supporting plate, a wheel seat and a rolling wheel, wherein the supporting plate is fixed to the inner side of the L-shaped support, the wheel seat is fixed to the supporting plate, and the rolling wheel is installed on the wheel seat. The rolling wheels of the pair of buffering rolling wheel devices are mutually and symmetrically clamped on tracks on two sides of the elevator guide rail with the guide rail as a symmetrical shaft. The outer side of the cross side and the outer side of the vertical side of each L-shaped support are connected with the shoe seat through bolts. The bolts are sleeved with springs and the springs are located between the L-shaped support and the shoe seat. The problem that the installing accuracy of a traditional guide shoe is difficult to control is solved. In addition, due to long-term usage, the guide rail is abraded, the springs play a self-adapting function and can still abut against the guide rail, and stable running of an elevator is ensured.

Description

technical field [0001] The invention relates to the field of elevator equipment, in particular to an elevator roller guide shoe. Background technique [0002] The guide shoe is a sliding nylon block between the elevator guide rail and the car. It is called a guide shoe. It can fix the car on the guide rail so that the car can only move up and down. There is an oil cup on the upper part of the guide shoe to reduce the lining For friction with the guide rail, 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 gear seat at the bottom of the car; four sets of counterweight guide shoes are installed on the bottom and upper part of the counterweight beam, fixed The guide shoes on the car can move up and down along the fixed guide rail installed on the well wall of the building to prevent the car from deflecting or swinging during operation. The elevator guide shoes are divided into rol...
