Description
Technical Field
The invention relates to the technical field of elevator equipment, in particular to an elevator guide rail installation accuracy detection device and method.
Background
The result of the elevator installation and debugging work is judged, the running vibration performance of the elevator car is a core index, and the installation accuracy of the guide rail is one of key influence factors, so that the accuracy detection of the elevator guide rail in the installation and debugging process is required. In the process of vertically installing guide rails in a well and debugging the performance of an elevator, the installation precision of two corresponding guide rails is required to be detected, and the detection indexes mainly comprise the perpendicularity, the opposite direction and the track gauge of the guide rails. Perpendicularity refers to the straightness of the working surface in the same direction as the guide rails of the same group and the parallelism relative to the plumb line. The opposite degree refers to the parallelism of the working surfaces on the same side of the two groups of guide rails and the axis coincidence degree of the corresponding top surfaces. The gauge refers to the distance between the two sets of rails relative to the top surface.
In the conventional inspection work, a field operator usually uses a rigid ruler to select a point to measure the distance between the working surface of the guide rail and the plumb line, records data of each measuring point and compares the data with a standard value. And judging whether the perpendicularity and the subtending degree of the guide rail are qualified according to whether the data of each measuring point meet the allowable error standard. And the distance between the corresponding top surfaces of the two groups of guide rails is measured by using a rail calibrating ruler for selecting points, the data of each measuring point is recorded and compared with a standard value, and whether the guide rail gauge is qualified is judged according to whether the data of each measuring point meets the allowable error standard. The detection mode is mainly manually operated by operators, and the data is read by human eyes, so that errors are easy to occur, and the measurement accuracy is low. And the operator can measure a plurality of data on the whole guide rail, so that the working strength is high and the measuring efficiency is low.
