Bending resistance detection device for elevator guide rail production

Abstract

A bending resistance detection device for elevator guide rail production belongs to the technical field of elevator detection. The device comprises a body, the body is a rectangular block, a display is fixedly mounted at the rear end of the right wall of the body, the display is an existing technology and is not discussed in the prior art, a display screen is fixedly mounted on the right wall of the display, and a switch is fixedly mounted at the front end of the right wall of the body. In the present invention, extrusion grooves and stabilizing blocks are arranged, during use, an elevator guide rail to be detected is placed in two groups of fixing plates on the body, the two groups of stabilizing blocks on the fixing plates are extruded by the guide rail to drive functional springs in theextrusion grooves to deform, and the functional springs reversely extrude the elevator guide rail. As the surfaces of the stabilizing blocks incline from top to bottom to the sides, away from each other, of the two groups of stabilizing plates, the elevator guide rail is prevented from being separated from the fixing plates upwards. As the surfaces of the stabilizing plates are rough, the friction force between the stabilizing plates and the elevator guide rail is increased, the effect of stabilizing the elevator guide rail on a workbench is achieved, and the detection efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of elevator detection devices, and in particular relates to a bending resistance detection device for elevator guide rail production. Background technique [0002] Elevator guide rails are elevator components composed of steel rails and connecting plates, which are divided into car guide rails and counterweight guide rails. From the cross-sectional shape, it can be divided into three types: T-shape, L-shape and hollow. While the guide rail plays a guiding role, it also bears the impact force of the car and elevator braking, and the impact force of the safety gear during emergency braking. The magnitude of these forces is related to the load and speed of the elevator, so guide rails should be selected according to the speed and load of the elevator. It is usually called the car guide rail as the main rail, and the counterweight guide rail as the auxiliary rail. [0003] In the elevator guide rail productio...

AI Technical Summary

Problems solved by technology

[0003] In the elevator guide rail production project, in order to ensure the production quality of the elevator guide rail, it is often necessary to test its bending resistance. The existing detection device has a simple structure, and the elevator guide rail is not firmly fixed when it is tested. There will be shaking, which will affect the detection results and lead to low detection efficiency
