Embodiment Construction

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0035] In the embodiment, an escalator is taken as an example, and the detection process of the moving sidewalk is completely the same, and will not be repeated.

[0036] Such as figure 1 As shown, the detection steps are as follows:

[0037] S1, initialize the controller and enter the escalator parameters, that is, enter the nominal width z of the escalator, the inclination angle α, the number of ramp steps n, and the slope length l, according to GB16899 "Safety Code for the Manufacturing and Installation of Escalators and Moving Walks" 5.4. 2.1.3.1 Table 2 stipulates that the load capacity of each step is determined, and the rated load capacity is calculated according to the number n of safety regulations for the manufacture and installation of slope step escalators and moving walk...

Abstract

The invention belongs to the field of braking performance of escalators or moving sidewalks and particularly relates to a method of determining stopping distance of an escalator or moving sidewalk. According to the method, no-load stopping distance and light-load stopping distance are measured by two running tests in no-load and light-load states, and the stopping distance of the escalator or moving sidewalk under the load smaller than or equal to rated load can be obtained through a mathematical model. The method is convenient, fast and safe; test results are accurate and reliable. Testing by a heavy-load test is not required, testing efficiency is greatly improved, damage of a lower device of the escalator or moving sidewalk, caused by braking performance not meeting the requirements when the load test method is used is avoided, and testing is less risky. The method has few measurement steps, workload is low, measurement efficiency is high, safety is high and determination results are accurate.

Description

Technical field [0001] The invention belongs to the field of braking performance of escalators or moving walks, and particularly relates to a method for determining the stopping distance of escalators or moving walks. Background technique [0002] The braking performance of escalators and moving walks has a great impact on their safety performance. Therefore, the corresponding national standards and technical specifications have stipulated their braking performance, and the escalators and moving walks are balanced under no-load conditions. Specific requirements are put forward for the stopping distance under the load condition; at the same time, the load on each step is determined for the escalator according to the nominal width of the step for the rated load test. [0003] National standards and technical specifications stipulate that all rated loads shall be concentrated on the upper 2 / 3 steps of the escalator or moving sidewalk for testing; therefore, during the rated load test,...
