Embodiment Construction

[0052] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.

[0053] exist figure 1 The method for testing the braking capacity of an escalator in the illustrated embodiment of the invention comprises the following steps:

[0054] Step A: Provide a test flywheel 1, in order to minimize the weight of the test flywheel 1, such as Figure 4 As shown, the shape of the test flywheel 1 adopts a hollow circular sleeve structure, its inner diameter is r, the outer diameter is R, and the height is H, then the moment of inertia J of the test flywheel 1 can be obtained by the formula:

[0055] inferred, J = 1 2 MR 2 - 1 2 mr 2 ...

Abstract

The invention relates to a method for testing the braking capacity of an escalator and/or a moving pavement. The method includes the steps of providing a testing flywheel, enabling the testing flywheel to be installed at the shaft end of a driving motor to replace the energy consumed by the transmission friction force in the brake stopping process, wherein the transmission friction force is increased by energy changes and testing load bearing of testing loads placed on a stair and/or a pedal in the brake stopping process when the brake stopping distance upper limit is achieved, starting the escalator and/or the moving pavement, starting a brake device for conducting brake stopping on the stair and/or the pedal when the stair and/or the pedal achieve/achieves the operation nominal speed, testing the brake stopping distance of the testing flywheel from starting brake stopping to stopping of the stair and/or the pedal, and comparing the brake stopping distance of the testing flywheel with the brake stopping distance upper limit, and judging whether the brake stopping distance when the testing loads are loaded exceeds the brake stopping distance upper limit or not. According to the method, the testing flywheel can be easily assembled and disassembled, the testing process is simple, the testing cost is reduced, and the inspection efficiency is improved.

Description

technical field [0001] The invention relates to a method for testing the braking capacity of escalators and / or moving walks. Background technique [0002] The braking capacity of the escalator and moving walkway braking device should be within an appropriate range. If the braking capacity is too strong, the braking deceleration will be large, and sudden braking will easily cause passengers to fall forward; if the braking capacity is too weak, the If the braking deceleration is too small, the escalator or moving walk cannot stop safely in time or even accelerate downward, which will increase the risk of personal injury to passengers. Therefore, the actual braking capacity detection of escalators and moving walks is a very important inspection item to ensure safety. [0003] The general braking system of the driving host is to stop the operating system of the driving host by friction torque to brake the escalator or moving walkway running at the rated speed. Its mechanical es...
