Description

Technical Field

[0001] This utility model relates to the field of elevator guide rail spacing detection technology, specifically an adaptive elevator guide rail spacing detector. Background Technology

[0002] A guide gauge is a specialized device used to measure whether the distance between elevator guide rails conforms to installation specifications. Its function is to ensure the stability and safety of the elevator during operation. This type of equipment typically has high-precision measurement capabilities, able to detect guide rail spacing data and deviations, providing data support for elevator installation, commissioning, and routine maintenance.

[0003] In existing technologies, elevator guide rail spacing detection usually requires the use of a measuring tape. During measurement, the tape needs to be manually tightened, and the measurement requires bending over to read the value. The deviation in angle and uneven tension can easily lead to large measurement errors. During operation, one person needs to hold the end of the tape measure while the other pulls the tape measure to read the value. The two people working together need to communicate and confirm the steps frequently, which makes it difficult to achieve efficient assembly line operation, increases labor costs, and the measuring tape can only measure the track gauge and cannot simultaneously detect the levelness of the guide rail.

[0004] Therefore, this utility model provides an elevator guide rail spacing adaptive detector that is easy for single-person operation, has a certain amount of retractable space, and can perform levelness detection during installation. Utility Model Content

[0009] Preferably, both the inner sides of the measuring ruler and the telescopic ruler are fixedly connected to sliders, and both the telescopic ruler and the telescopic ruler are provided with sliding grooves on their sides. The slider on the inner side of the measuring ruler is slidably engaged with the sliding groove on the side of the telescopic ruler, and the slider on the inner side of the telescopic ruler is slidably engaged with the sliding groove on the side of the telescopic ruler.

[0010] Preferably, a fixing block is fixedly connected to the upper surface of the measuring ruler, and a fixing component is provided on the fixing block.

[0011] Preferably, the fixing component includes a fixing groove, a button is slidably connected to the inside of the fixing groove, a compression spring is fixedly connected to the bottom of the button, the side of the compression spring away from the button is fixedly connected to the fixing groove, and a retaining plate is rotatably connected to the side of the button.

[0014] The beneficial effects of this utility model are:

[0015] (1) The elevator guide rail spacing adaptive detector described in this utility model achieves quick engagement of the detector with the guide rail through the cooperation of the detection ruler, telescopic ruler two and telescopic ruler three, reducing the occupation of the operating space in the shaft.
