Novel elevator roller guide shoe

Abstract

The invention relates to a novel elevator roller guide shoe. The novel elevator roller guide shoe comprises a mounting plate, a roller group is arranged on the mounting plate, and the roller group comprises two side rollers abutting against the opposite side walls of an elevator guide rail and a front part roller leaning against the directly-facing side wall of the elevator guide rail; the side rollers and the front part roller are correspondingly and rotatably connected with the mounting plate through a first swinging arm and a second swinging arm, the first swinging arm comprises a first connecting plate and a first rotating plate, a position sensor is arranged on the bottom wall, deviating from the side rollers, of the first rotating plate, and a laser aligner mutually matched with theposition sensor is arranged at the bottom of a well; an elastic mechanism is arranged on the first rotating plate; and an adjusting mechanism for abutting against the two sided roller to be close to each other or away from each other is arranged on the mounting plate. The novel elevator roller guide shoe has the advantages that during the test run of an elevator, an angle of inclination of the guide rail can be detected through the cooperation of the guide shoe and the guide rail, then potential safety hazards of elevator running are checked, and frictional force of the guide shoe with the guide rail in the using process can be reduced.

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...

AI Technical Summary

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
