Description

Technical Field

[0001] The utility model relates to the technical field of elevator guide rail detection, in particular to an elevator guide rail detection device. Background Technique

[0002] An elevator guide rail is an elevator component composed of a steel rail and a connecting plate, and is a safe rail for an elevator to travel up and down in a hoistway. The guide rail is installed on the hoistway wall and is fixedly connected to the hoistway wall by a guide rail frame and a guide rail bracket. The commonly used guide rail of an elevator is a "T"-shaped guide rail, which has the characteristics of strong rigidity, high reliability, safety and low cost. The surface of the guide rail must be smooth without obvious unevenness. After the elevator guide rail is processed, it is necessary to detect whether the straightness is qualified to ensure the product quality.

[0003] In the prior art, the straightness detection of elevator guide rails mostly relies on manual operation. However, through manual detection, there are problems of time-consuming, laborious, low detection accuracy, and the detection results cannot be directly presented. Therefore, it is necessary to propose an elevator guide rail detection device to solve the above-mentioned problems. Content of the Utility Model

A drawing board in contact with the rear side of the marker pen is installed between the two vertical plates.

[0007] The upper end surface of the placement table is fixedly connected with a fixed clamping plate that abuts against the right end of the guide rail. The left end of the left vertical plate penetrates and is threadedly connected with a second screw rod. The right end of the second screw rod is rotatably connected with a movable clamping plate that abuts against the left side of the guide rail. The movable clamping plate is slidably connected to the upper end surface of the placement table through a chute.

[0008] In order to facilitate the positioning of the placement position of the guide rail, as an optimization of an elevator guide rail detection device of the present invention, a positioning plate that abuts against the rear end of the guide rail is fixedly connected to the upper end surface of the placement table.

Then the spring is compressed, and the ball is in contact with the left side of the upper end of the guide rail. Then, by moving the movable clamping seat to the left and cooperating with the fixed clamping seat, the marker pen can be clamped and fixed, and the pen tip at the rear of the marker pen is in contact with the drawing board. Then, by pushing the frame and the connecting cylinder to the right, the ball will roll on the upper end of the guide rail. When there are protrusions or depressions on the guide rail, the spring will be shortened or elongated, and at the same time, the drawing trajectory of the marker pen will also fluctuate until the detection of the guide rail is completed. Thus, through this detection method, the effects of time and labor saving, high detection accuracy, and the ability to directly present the detection results can be achieved.
