Escalator step loading test device

Abstract

The invention provides an escalator step loading test device, which comprises a loading base, a loading pressing block, a loading connecting rod, a loading execution part and a proportional loading unit, wherein the loading base is fixedly connected to step teeth of a step; the loading pressing block is located on the step, and the loading pressing block and the loading base are arranged in parallel; the loading connecting rod comprises a transverse rod and a vertical rod which are perpendicular to each other; the lower end of the vertical rod is connected with the upper end face of the loading pressing block; the upper end of the vertical rod is fixedly connected with one end of the transverse rod; the transverse rod is located above the step; the loading execution part and the vertical rod are arranged in parallel; the loading execution part comprises a fixed part and a telescopic part; the upper end of the telescopic part is fixedly connected to the other end of the transverse rod; the lower end of the telescopic part is in telescopic connection with the upper end of the fixed part; the lower end of the fixed part is fixedly connected to the upper end face of the loading base; the proportional loading unit is used for providing a variable load for the loading execution part; the vertical rod is provided with a force sensor; and the loading pressing block is provided with a displacement sensor.

Description

technical field [0001] The present application relates to the technical field of step testing, in particular to an escalator step loading test device. Background technique [0002] The steps are important load-bearing components of the escalator. During the long-term operation of the steps, the steps are prone to deformation and insufficient strength of the steps. The need is becoming more and more urgent. In the traditional test method, the cascade test is mainly carried out in the laboratory through special equipment. The laboratory test cannot fully reflect the actual working conditions of the cascade. Using weights to load the steps requires a lot of manpower and material resources, and the loading of the steps cannot be accurately realized, and the deformation of the steps cannot be accurately recorded at the same time. [0003] Therefore, it is necessary to provide an improved technical solution for the above-mentioned deficiencies in the prior art. Contents of the...
