Abstract

The invention discloses a stair deflection testing tool. The tool comprises a workbench, a clamping mechanism, a supporting mechanism, a testing driving mechanism, a sensor and a stair pressing head;the supporting mechanism is arranged on the upper end face of the workbench, the testing driving mechanism is installed on the supporting mechanism, the sensor is installed at the output end of the testing driving mechanism, the clamping mechanism is installed on the upper end face of the workbench, the clamping mechanism is used for limiting a stair part, the stair pressing head comprises a knuckle bearing sleeve and a pressing shaft, the knuckle bearing sleeve is connected with the output end of the testing driving mechanism, one end of the pressing shaft is connected with the knuckle bearing sleeve, and the other end of the pressing shaft is connected with the clamping mechanism. The stair deflection testing tool has the advantages that the structure is simple, the device is designed through modular combination, standardized production is achieved, adjustment and installation are facilitated, and good universality and convenience are achieved.

Description

technical field [0001] The invention relates to the technical field of step testing, in particular to a step deflection testing tool. Background technique [0002] The steps are the components that circulate on the escalator truss for passengers to stand on. These steps are generally assembled and combined by pedals, kick plates, brackets, sprocket shafts, step tugs, and step sprockets. Existing step test equipment conducts deflection tests on the steps, and by simulating people stepping on the steps, it is tested how much deformation or failure the steps will produce under the action of force in the worst environment. According to the requirements of relevant standards, the steps need to be tested in various ways, and the installation methods of the steps may be different for different test methods. However, the existing step test equipment has a complex structure and is inconvenient to install, which is far from meeting the relevant requirements of the step test. Conten...
