Embodiment Construction

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

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

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

[0037] S1, initialize the controller, input the parameters of the escalator, that is, input the nominal width z of the escalator, the inclination angle α, the number of slope steps n, and the length of the slope l, according to GB16899 "Safety Specifications for the Manufacture and Installation of Escalators and Moving Walks" 5.4. Table 2 of Article 2.1.3.1 stipulates that the load capacity of each step is determined, and the rated load capacity, that is, the rated load m, is calculated according to the safety specification number n for the m...

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, in particular 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, so the corresponding national standards and technical specifications have stipulated their braking performance, and the escalators and moving walks under no-load and rated Specific requirements are put forward for the braking and stopping distance under the load state; at the same time, the rated load test is carried out on the escalator according to the nominal width of the steps to determine the load on each step. [0003] National standards and technical specifications stipulate that all rated loads should be tested on the upper 2 / 3 steps of the escalator or moving walk; therefore, during the load test, the running distance between the st...
