Description
Technical field
The utility model belongs to escalator and moving sidewalk detecting device technical field, is specifically related to a kind of escalator and moving sidewalk stop characteristic detection device
.
Background technology
Escalator is a kind of with circulating motion ladder road, for the fixing power driven equipment of the conveying people that tilts up or down; Moving sidewalk is board-like or belt-type cycle runs aisle, is not more than the fixing power driven equipment of 12 ° of transport of passengers for level or leaning angle; Escalator and moving sidewalk are by compositions such as drive system, terraced road system, handrail system, control and safety guards; all the equipment collecting mechanical, electrical integration; use quite general in the public place that the stream of peoples such as subway station, Railway station, airport, harbour, mansion, market comparatively concentrate; but the casualty accident of escalator, moving sidewalk happens occasionally, its safe operation uses most important.Therefore, escalator as public place transport facility and included in the management of special equipment respectively by state compulsion, and formulated relevant criterion and the specifications such as manufacture, installation, maintenance maintenance.
About the design safety requirement of escalator and moving sidewalk service brake, in GB16899-2011 " manufacture and the installation safety standard of escalator and moving sidewalk ", 5.4.2.1.3.2 joint defines the deceleration/decel along sense of motion in brake process when the braking distance of escalator and escalator run downwards, the deceleration/decel along sense of motion in brake process when 5.4.2.1.3.4 joint defines the braking distance of moving sidewalk and moving sidewalk level or runs downwards; On the whole, escalator and the requirement of moving sidewalk to braking procedure are should " jail of stopping ", again " that stops is steady "; The braking distance that " jail of stopping " is reflected in escalator and moving sidewalk can not be greater than limit value; The stop deceleration/decel that " that stops is steady " is reflected in escalator and moving sidewalk can not be greater than limit value, makes escalator and moving sidewalk with close to even deceleration/decel stop as far as possible, avoids the excessive passenger of causing of deceleration/decel to fall down.
But along with the place in operation of escalator, the wearing and tearing of brake coil adhesive frequently, brake block all can cause braking, brake coil adjusts the situation generations such as not in place, the braking characteristics of drg all can be made can not to meet the requirement of GB16899-2011 " manufacture and the installation safety standard of escalator and moving sidewalk ", thus bring risk to the safe operation of escalator and moving sidewalk.For guaranteeing the safe operation of escalator and moving sidewalk, the installation of national regulation escalator and moving sidewalk, transformation, maintenance, use should according to TSG7005-2012 " elevator surveillance be checked and periodical survey rule-escalator and moving sidewalk ", exercised supervision by special equipment inspection mechanism and check and periodical survey, being up to the standards can place in operation.
At present the test method of escalator and moving sidewalk stop characteristic is mainly contained:
(1) by range estimation match line manual stop method: draw match line respectively on the pedal skirt panel of escalator or moving sidewalk, make before the match line on pedal is positioned at skirt panel match line on escalator or moving sidewalk moving direction, first tested escalator or moving sidewalk is started during measurement, when the match line guaranteeing on pedal moves to overlapping with the match line on skirt panel, escalator and moving sidewalk can reach the test run speed of regulation; During test, tester's hand, by the manual stop button of escalator or moving sidewalk, while the match line of estimating skirt panel and step or pedal just in time aligns, presses the manual stop button of escalator or moving sidewalk; After escalator or moving sidewalk come to a complete stop, measure the distance of two match lines at escalator or moving sidewalk service direction, be the braking distance of escalator or moving sidewalk; Simultaneously with the time that stopwatch is measured alignment and come to a complete stop, the stop deceleration/decel of escalator or moving sidewalk can be calculated.
This method of measurement by match line between range estimation skirt panel and step or pedal, range estimation is all leaned on manually with manual, there is larger time delay, cause measured error larger during execution.
(2) by detecting the rotation number of teeth of drive sprocket: application number 201110408320.7, patent name is the utility application of stopping distance overrun testing device on escalator or moving sidewalk, disclose stopping distance overrun testing device on a kind of escalator or moving sidewalk, when drive motor drives escalator or moving sidewalk to operate, rosette rotates together along with drive sprocket, proximity transducer can respond to tooth on rosette and teeth groove, often sense a tooth and adjacent teeth groove, then proximity transducer can export a square waveform pulse.Control module and proximity transducer communicate, once escalator or moving sidewalk generation stop, then control module detects stop signal, now to the step-by-step counting that proximity transducer exports, because the number of pulses of sensor is directly proportional to the stopping distance of escalator or moving sidewalk, therefore by count pulse quantity, can stopping distance be indicated.
This test method measures the stop characteristic of escalator and moving sidewalk by the method detecting the rotation number of teeth of drive sprocket, and resolution is escalator and moving sidewalk main drive wheel two gear spacing, and therefore survey precision is not high.
(3) tested by vibration measuring set: application number 201210064642.9, patent name are the utility model patent of elevator running performance in-line analyzer and on-line analysis, propose and utilize the acceleration/accel of vibration to obtain the speed values of measured body vibration to time integral, speed values is obtained the test method of the displacement information of measured body to time integral, directly can measure the stop deceleration/decel of escalator and moving sidewalk, and calculate the braking distance of escalator and moving sidewalk.
The stop characteristic of escalator and moving sidewalk is tested by vibration measuring set, project testing requirement can be met, also there is the feature that measuring accuracy is high, but because vibration measuring set is all universal, cannot fixedly secure on the pedal of escalator or moving sidewalk, easily slide on step or pedal during test, cause test result inaccurate.And usually costly, complex operation, is unfavorable for that elevator on-site inspection uses to this vibration measuring instrument.
In a word, each special equipment inspection mechanism is not yet sought at present can simple, the method for implementing escalator or the characteristic test of moving sidewalk stop accurately and effectively, actual detection in enforcement easily causes measured error large, even because too loaded down with trivial details and undetected phenomenon, thus hide some dangers for the safe operation of escalator and moving sidewalk.
