Embodiment Construction

[0020] according to Figure 1~6 The specific structure of the present invention will be described in detail. The testing equipment for the braking performance of the additional brake includes a traction machine 2 controlled by a frequency converter 1. The traction machine 2 is driven by the large and small drive sprockets 16, 12 and is provided with a main drive 4 with an additional brake 3. The main drive 4 Components such as the energy conversion device 6 driven by the large and small transmission sprockets 17, 21 and the detection control circuit. The operating speed of the equipment is controlled by the frequency converter 1, and the frequency converter 1 changes the output frequency so that the main transmission shaft 18 of the traction machine 2 can obtain a certain speed, and the small drive sprocket 12 on the traction machine 2 is driven by the drive chain 10 to The speed is transmitted to the large drive sprocket 16 on the main drive 4, and the large drive sprocket 1...

Abstract

Provided is equipment for detecting the braking performance of an additional brake. The problems that in the prior art, testing is troublesome, the workload is large, precision is low, and the simulation height is limited are solved. The equipment comprises a traction machine, a main drive, an energy conversion device and a detecting control loop. The equipment is technically characterized in that the energy conversion device is composed of a transmission energy storage wheel, a small transmission chain wheel and an angular velocity sensor; a large driving chain wheel and at least one large transmission chain wheel are assembled on a main transmission shaft of the main drive; and the main drive drives a transmission shaft of a transmission to rotate at a high speed, the rotating speed of the energy storage wheel achieves constant-speed running, rotating energy of an equivalent actual load provided by the energy conversion device is transferred to the main drive, and the additional brake is started to lock a friction disk for friction consumption till the main drive stops rotating. The equipment is reasonable in structural design and easy to operate, simulation of load energy during in-plant testing is equivalent to actual working conditions, and secondary debugging is not needed during field tests, so that the workload is reduced, and work efficiency and testing accuracy are improved.

Description

technical field [0001] The invention relates to a device for detecting the braking ability and braking stability of a brake, in particular to a device for detecting the braking performance of an additional brake used for an escalator or a moving walkway. Background technique [0002] The braking capacity of the additional brakes of escalators and moving walks should be within an appropriate range to ensure safe operation. The relevant standards must meet the deceleration a≤1m / s 2 requirements. The main reason is: the braking force is too strong, the greater the deceleration, it will cause the danger of passengers topple over. If the braking force is too small, the deceleration will be too small, which will cause the escalator to fail to stop when it is dangerous. Therefore, the size of the deceleration of the additional brake is an important performance testing item. [0003] The additional brake is based on the principle of friction, using the friction force provided by ...
