Description
Technical field
This utility model relates to a kind of equipment for detecting brake ability and insensitivity, the detection equipment of the additional brake braking ability of a kind of escalator or moving sidewalk.
Background technology
Escalator should just can ensure that the safety of operation with the stopping power of the additional brake of moving sidewalk in a proper range, and correlation standard must is fulfilled for deceleration a≤1m/s2Requirement.Main cause is: brake force is too strong, and deceleration is the biggest, and passenger can be caused to topple over danger.Brake force is too small, then deceleration is too small, cannot the situation such as stop occur when can cause staircase danger.Therefore, the size of additional brake deceleration is an important performance detection project.
Additional brake is the principle by friction, and the frictional force utilizing friction plate to provide acts in main driving, reaches the purpose of braking.During onsite acceptance inspection, needing every staircase carries out fully loaded stop test, the brake force of additional brake needs to be adjusted according to different hoisting depths at the scene, meets the requirement of deceleration, but because on-the-spot working place is little, therefore debug the most thorny difficulty.At present a lot of Elevator Factories are fixed value when dispatching from the factory to the brake-force control of additional brake, hoisting depth are not connected with brake force, exist the most highly staircase cannot stop, the various problems that low height staircase deceleration is big.If annual, escalator carrying out fully loaded braking performance test, then repeatedly braking can make the coefficient of friction of friction plate change, even if scene was checked qualified at that time, still can there is potential safety hazard in follow-up operation.Traditional counterweight that utilizes replaces the method running load to additional brake test, not only needs to carry the heaviest counterweight iron block, wastes time and energy, and if operationally braking the damage that also can cause equipment out of control.
According to Patents, once recorded and changed traditional method of testing, " a kind of flywheel replaces the method for counterweight test escalator stopping power " such as Publication No. 104150338A, technical scheme disclosed in the method, replaces, in counterweight test process, needing repeatedly to remove and install the flywheel at motor shaft end with flywheel, load onto corresponding fully loaded counterweight, under conditions of brake force is constant, measure fully loaded braking distance, compare with flywheel with by the surveyed braking distance of counterweight and deviation；Then measure the measurement distance of escalator with the flywheel of certain specification, thus judge the braking distance that escalator is fully loaded, if the upper limit complied with the national standard requirements.Although the inconvenience of carrying counterweight when finally eliminating onsite acceptance inspection, but the method is replacing in counterweight test with flywheel, remain a need for repeatedly carrying the counterweight that experiment acquired results needs, the most do not save the hard work of carrying counterweight, but also want continuous dismounting and change record, the different size calculated, the flywheel of Different Weight, carry out running the comparison of load, both wasted time and energy, again it is difficult to ensure that accuracy of measurement.
A kind of method testing escalator and/or moving sidewalk stopping power in Publication No. 103395680A, disclosing the mode utilizing driving host axle head to change flywheel in its technical scheme replaces counterweight to carry out simulation load, the rotational energy produced when rotating with flywheel, the energy consumed during replacing being supported on stop on escalator, it is intended to reach to test the purpose of moving sidewalk stopping power.But the program needs continuous superposition flywheel, so relatively big on electric machine main shaft impact, main shaft fracture can be caused in the course of time or because bias causes damaging motor.The flywheel that quality is excessive simultaneously can make driving host not have enough staring torques, and the method only utilizes the flywheel on main frame to be simulated load energy, because flywheel can not infinitely increase, therefore motor cannot provide bigger corresponding staring torque, and big height staircase load will be caused to be difficult to simulation.
In sum, these two disclosed patents all simulation loads in the way of changing or changing main frame flywheel, but while changing flywheel, but change the unitary rotation inertia of drive system, therefore cannot simulate actual condition accurately；The result of its test is linear expression, can not embody the corresponding relation of concrete load value and brake force；The method used needs practical operation at the scene, field adjustable in test process, considerably increases the workload of on-the-spot test.And when measuring braking distance, because have employed the modes such as manual measurement, therefore cause the data tested inaccurate.
