Tool for measuring verticality of side plate of elevator framework

Abstract

The invention discloses a tool for measuring verticality of a side plate of an elevator framework. The tool comprises an electromagnetic base. At least two positioning pins are arranged on the electromagnetic base. A guide post which is perpendicular to the electromagnetic seat is arranged on one side, near the positioning pins, of the electromagnetic base. A linear guide rail is slidably connected with the guide post and connected with the positioning pins in a linear parallel manner. A dial indicator is slidably connected to the linear guide rail. The tool is capable of precisely measuring data of the verticality of the side plate of the elevator framework, so measurement precision is ensured and inaccuracy caused by quite big errors caused by tedious operation of workers can be avoided.

Description

technical field [0001] The invention belongs to the field of elevator measuring tools, and more specifically relates to a tool for measuring verticality of elevator frame side plates. Background technique [0002] After the side plate of the elevator frame is welded, it is necessary to measure the angle of each welding point to ensure the verticality between the two plates. At present, the existing detection usually takes one side of the frame side plate as the reference plane. Place a plate on the surface, and at the same time make a part of the plate protrude out of the frame side plate, then place a square on the plate, and then use a feeler gauge to measure the data of the frame side plate to check whether the frame side plate is qualified, but this method requires work. The personnel have skilled operation, and they are accurate when placing the plate, square and feeler gauge. However, since each part is placed manually by the testing staff, the uncontrollable factors a...

[0002] After the side plate of the elevator frame is welded, it is necessary to measure the angle of each welding point to ensure the verticality between the two plates. At present, the existing detection usually takes one side of the frame side plate as the reference plane. Place a plate on the surface, and at the same time make a part of the plate protrude out of the frame side plate, then place a square on the plate, and then use a feeler gauge to measure the data of the frame side plate to check whether the frame side plate is qualified, but this method requires work. The personnel have skilled operation, and they are accurate when placing the plate, square and feeler gauge. However, since each part is placed manually by the testing staff, the uncontrollable factors are relatively large, and at the same time, the small contact surface between the square and the plate leads to errors, which makes the measurement Not accurate enough
