Description
Technical Field
The invention relates to the field of escalator and moving sidewalk braking systems, in particular to a device and a method for setting braking torque of a main shaft brake.
Background
An additional brake represented by a main shaft brake is used as a redundant safety guarantee, and can directly apply enough braking torque to the main shaft under the conditions of failure of a working brake, chain breakage of a driving chain, driving displacement and the like, so that dangerous conditions of reversion, vehicle sliding, descending overspeed and the like of the escalator are avoided. However, the braking torque of the spindle brake cannot be too high, which would otherwise lead to the risk of the passengers falling over. For this purpose, in GB16899 it is proposed that "additional brakes" should be able to effectively decelerate and stop escalators and moving walkways running downwards with a braking load and to keep them stationary. The deceleration should not exceed 1m/s 2. "requirement, and at the same time, the standard also states that" the braking distance required for the service brake (GB16899-20115.4.2.1.3) does not have to be guaranteed when the additional brake is activated ".
In the design process, a designer usually does not directly use standard requirements as the ex-factory debugging requirements of the escalator, but provides additional brake braking torque through strict calculation to meet the requirements of effectively braking the escalator in the standard, and the deceleration does not exceed 1m/s2The requirements of (1). Conventional main shaft brakeThe dynamic torque is obtained by an indirect method, namely the positive pressure of the friction plate is indirectly controlled by controlling the fastening torque of the bolt, and the method has larger deviation under the influence of the friction coefficient between the friction plate and the ratchet wheel, the friction coefficient of the thread pair, the quality of the thread pair, the accuracy of a torque wrench and the like. The tool is also used for applying static load to the additional brake to enable the friction pairs to rotate just, the static load at the moment is used as braking torque of the additional brake, and large errors exist due to large difference from the actual working condition (actually, the braking torque output in the continuous rotation process).
With the increasing of the quantity of the staircase, the action of the main shaft brake occurs for many times, but the car sliding accident caused by the fact that the actual braking torque does not reach the designed value causes great personal and property loss. The reason is that at present, a reliable device for testing and setting the braking torque is not available for ensuring that the actual braking torque of the additional brake meets the design requirement. Therefore, there is a strong need for a braking torque setting device and method with higher reliability and more accurate setting method.
