Abstract
The invention relates to a handrail speed measuring part, belonging to the technical field of handrails. The handrail speed measuring part is composed of an angular piece, a sleeve, a rolling wheel bracket, a speed measuring rolling wheel, a compression spring and a speed measuring photoelectric part, wherein one end of the angular piece is fixedly mounted on a truss by using a bolt and the other end of the angular piece is connected with the sleeve; the sleeve and the rolling wheel bracket are welded together; the speed measuring rolling wheel is provided with a small speed measuring hole; the compression spring is mounted on the sleeve between the angular piece and the rolling wheel bracket; and the speed measuring photoelectric part penetrates through the inner part of the sleeve. According to the handrail speed measuring part, the speed measuring rolling wheel is tightly pressed on a handrail through pressure generated by compressing the spring; when the handrail moves, friction force is generated to drive the speed measuring rolling wheel to move together; the speed measuring photoelectric part can measure the linear speed of the handrail through the small speed measuring hole in the speed measuring rolling wheel; and when the handrail has an abnormal speed, a signal can be rapidly and effectively sent to a main control cabinet so that an escalator or an automatic side pavement stops running.
Description
technical field:
The present invention relates to a kind of handrail to test the speed parts, belong to staircase technical field.
background technology:
The handrail parts that test the speed are a kind of staircase components guaranteeing that staircase normally runs.In GB16899-2011,5.6.1 has made relevant regulations to handrail running velocity: the running velocity of handrail is 0% ~ 2% relative to the franchise of step, pedal or adhesive tape actual speed under normal operating conditions.Handrail speed monitoring should be provided, when running on escalator and footway, when handrail speed deviations step, pedal or adhesive tape actual speed are greater than 15% and time length is greater than 15s, should make escalator or moving sidewalk out of service.
summary of the invention:
Technical matters to be solved by this invention is: provide a kind of and can detect the handrail of speed that handrail runs and to test the speed parts, comprise test the speed roller and the photoelectricity that tests the speed.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: a kind of handrail tests the speed parts, the described parts that test the speed are by angle-shaped piece, sleeve, rolling wheel support, test the speed roller, Compress Spring and the photoelectricity composition that tests the speed, described angle-shaped piece one end uses bolt to be fixedly mounted on truss, the other end and sleeve connection, described sleeve and rolling wheel support weld together, with the aperture that tests the speed on the described roller that tests the speed, described Compress Spring is arranged on the sleeve between angle-shaped piece and rolling wheel support, the described roller that tests the speed to be arranged on rolling wheel support and to fit tightly with handrail, the described photoelectricity that tests the speed is through sleeve inner.
Further, can regulating to make Compress Spring tests the speed fits tightly degree between spring and handrail, prevents sleeve from departing from from angle-shaped piece, is provided with back-up ring in the lower end of sleeve.
Compared with prior art, usefulness of the present invention is: the handrail parts that test the speed can record handrail speed effectively accurately, when ensureing that staircase and footway are run, there is velocity anomaly in handrail, master control cabinet can be sent a signal to fast and effectively, realize stop main frame, ensure passenger safety.
accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is front view of the present invention.
In figure: 1, truss, 2, angle-shaped piece, 3, sleeve, 4, rolling wheel support, 5, test the speed roller,
6, Compress Spring, 7, back-up ring, 8, test the speed photoelectricity, 9 handrails.
detailed description of the invention:
Describe the present invention below in conjunction with the drawings and the specific embodiments:
According to Fig. 1, a kind of handrail tests the speed parts by angle-shaped piece 2, sleeve 3, rolling wheel support 4, test the speed roller 5, Compress Spring 6 and the photoelectricity 8 that tests the speed form, described angle-shaped piece 2 one end uses bolt to be fixedly mounted on truss 1, the other end is connected with sleeve 3, described sleeve 3 and rolling wheel support 4 weld together, the described roller 5 that tests the speed to be arranged on rolling wheel support 4 and to fit tightly with handrail 10, with the aperture 9 that tests the speed on the described roller 5 that tests the speed, described Compress Spring 6 is arranged on the sleeve 3 between angle-shaped piece 2 and rolling wheel support 4, the described photoelectricity 8 that tests the speed is inner through sleeve 3.
According to Fig. 1, sleeve 3 bottom is provided with back-up ring 7.
During use, by the pressure that spring-compressed 6 produces, the roller 4 that makes to test the speed is pressed on handrail 10 tightly, when handrail 10 runs, producing friction force drives the roller 4 that tests the speed to move together, the photoelectricity 8 that tests the speed realizes recording handrail 10 linear velocity by the pin-and-hole 9 that tests the speed tested the speed on roller 4, the method is owing to there being Compress Spring 6 predetermincd tension, thus handrail 10 speed can be recorded effectively accurately, there is velocity anomaly in handrail 10, can send a signal to master control cabinet fast and effectively, escalator or moving sidewalk out of service.
It is emphasized that: be only preferred embodiment of the present invention above, not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
