A new type of elevator roller guide shoe

Abstract

The invention relates to a new type of elevator roller guide shoe, which includes a mounting plate, on which a roller set is arranged, and the roller set includes two side rollers supported on the opposite side walls of the elevator guide rail, and can be attached to the elevator guide rail. Facing the positive roller on the side wall; the side roller and the positive roller are connected to the mounting plate through the rotation of the first swing arm and the second swing arm respectively, the first swing arm includes a first connecting plate and a first rotating plate, the first A position sensor is provided on the bottom wall of the rotating plate away from the side rollers, and a laser collimator cooperating with the position sensor is provided on the bottom of the hoistway; an elastic mechanism is arranged on the first rotating plate; Adjustment mechanism for side rollers approaching and moving away from each other. The advantages of the present invention are: when the elevator is in trial operation, the inclination angle of the guide rail can be detected through the cooperation between the guide shoe and the guide rail, and then the potential safety hazards of the elevator operation can be checked, and the contact between the guide shoe and the guide rail during use can be reduced. of friction.

Description

technical field [0001] The invention relates to the technical field of elevator equipment, in particular to a novel elevator roller guide shoe. Background technique [0002] Elevator refers to the permanent transportation equipment that serves several specific floors in the building, and its car runs on at least two rigid rails that are perpendicular to the horizontal plane or at an inclination angle of less than 15° from the plumb line. The guide shoe is a sliding nylon block between the elevator guide rail and the car. It can fix the car on the guide rail so that the car can 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. 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 seat at the bottom of the car; four sets of counterweight guide shoes are installed on the bottom and...

Problems solved by technology

However, the existing guide shoes are generally designed as sliders. The sliders slide on the fixed guide rails, and the sliders and guide rails are prone to wear, and if the inclination angle of the guide rails is greater than 15°, unless the inclination angle of the guide rails is too large, the slider and the guide rails will Large frictional shaking is generated, otherwise it is difficult for the staff to find the inclination of the guide rail
