Adjustable elevator guide rail detecting device

Abstract

The invention discloses an adjustable elevator guide rail detecting device, comprising an aisle-tooth bottom plate, wherein the middle position of the aisle-tooth bottom plate is provided with an aisle-tooth gear; the aisle-tooth gear is meshed with guiding-rule sliding racks positioned at the two sides; aisle-tooth guiding rules are fixed at the outer sides of the guiding-rule sliding racks; the aisle-tooth guiding rules are connected with rotatable guiding-rule balance plates by rotating pins; the surfaces of the aisle-tooth guiding rules are provided with first-group scale lines; one end of each guiding-rule balance plate is a sharp-angled pointer; the pointers points at the first-group scale lines; the surface of the aisle-tooth bottom plate is provided with second-group scale lines along the moving direction of the guiding-rule sliding racks; and the aisle-tooth bottom plate is provided with guiding structures of the guiding-rule sliding racks. The adjustable elevator guide rail detecting device disclosed by the invention has the advantages that the structure is simple and reasonable, the cost is low, the carrying is convenient, the safety and reliability are achieved, and the distance between two pairs of heavy guide rails and the level degree of tongue surfaces of the guide rails can be conveniently and quickly detected.

Description

technical field [0001] The invention relates to an elevator car inspection device, in particular to an inspection device for elevator counterweight guide rails. Background technique [0002] The verticality and parallelism of the guide rails during elevator installation will directly affect the smooth operation of the elevator, affect the failure rate of the elevator, and affect the safety of elevator passengers. So it is very important. At present, for the inspection of elevator guide rails, a square is usually matched with a test board or a special square is used. However, in the process of installing the guide rails, how to control the distance between the guide rails on both sides and whether the same side of the guide rails are flush, etc., the Chinese invention patent No. 201120445298.9 discloses a guide rail detection device, the structure of which includes at least a pair of displacement A sensor, a mounting frame and a processing system. The end of the mounting fr...
