Description

TECHNICAL FIELD

[0001] The present application relates to the field of escalator manufacturing, in particular to a gap adjusting device between escalator steps and skirt boards. BACKGROUND

[0002] An escalator is a fixed power-driven device with circulating steps for transporting passengers up or down an inclined path. As an important passenger conveying device, escalators are widely used in public places such as shopping malls, hotels, subways and train stations. While providing convenience for people, escalators also bring potential personal injury accidents.

[0003] There is a certain gap between the escalator steps and the skirt boards. According to GB16899, the gap between the escalator steps and the skirt boards should not be greater than 4mm on either side, and the total gap measured at symmetrical positions on both sides should not be greater than 7mm. During the operation of the escalator, if the gap between the steps and the skirt boards is too large, foreign objects are likely to be caught in the steps, which can easily cause accidental injury accidents.

[0004] During the installation of the skirt board of the escalator, the installer needs to use a triangular ruler or a caliper to measure the gap between each step and the skirt board at all times. If the requirements are not met, adjustments need to be made. The traditional installation and measurement method is time-consuming and inefficient for installers, with large human errors, and it is difficult to ensure the stability of the gap value precision between the steps and the skirt boards of the entire escalator.

[0005] Patent CN210165905U proposes a escalator skirt board gap measuring device, which needs to select an initial position, place the device at the selected measurement point position, and then connect the related equipment to detect. It is an indirect measurement method. The disadvantages of this measuring device are: first, the structure is complex, more additional auxiliary equipment is used, and the operation is cumbersome; second, there are restrictions on the initial position, which needs to be leveled at a fixed position, increasing the operation and use difficulty; third, the device is directly placed on the steps, and the base is not fixed. When the escalator is running, it cannot accurately measure the gap value between the steps and the skirt boards.

[0006] Patent CN21062999U proposes an automatic escalator safety gap multifunctional detector. The device is fixed on the steps, and after adjusting the distance between the positioning reference plate and the skirt board, the gap value between the steps and the skirt boards is dynamically measured by the sensor. The disadvantages of this patent are: first, it is used to measure the gap value between the installed escalator steps and the skirt boards. If the gap value between the steps and the skirt boards is detected to be poor, it needs to be reinstalled; second, in dynamic testing, it cannot accurately locate the position where the gap value between the steps and the skirt boards does not meet the requirements.

[0007] Therefore, an ideal way is to directly determine the gap value between the step and the skirt plate when installing the skirt plate on the escalator. The gap value between the step and the skirt plate is adjusted to a required value during the installation of the skirt plate, so as to avoid detecting after the installation of the skirt plate is completed, and to avoid the need to disassemble the skirt plate and re-adjust the gap value between the step and the skirt plate when the detection is not good.
