Abstract

The utility model relates to a device for detecting synchronization of a hand strap and steps of an escalator. The technical scheme provided by the utility model is that a guide pulley rotation coder for detecting operation speed of the steps is additionally arranged on a guide pulley of the escalator, wherein a hand strap rotation coder for detecting the operation speed of the hand strap and a coder tensioning wheel are additionally arranged on the hand strap; the hand strap rotation coder is placed on the upper surface of the hand strap; and the coder tensioning wheel is placed on the lower surface of the hand strap, so that the hand strap rotation coder reliably rotate to detect the synchronous change condition of the guide pulley rotation coder and the hand strap rotation coder and emit audible and visual alarm in case of failure of synchronization. The device has the beneficial effects of accuracy, quickness, convenience and capabilities of emitting the audible and visual alarm when the steps and the hand strap are not synchronous, stopping operation of the escalator, giving an alarm by the system to a monitoring center through a network transmission module and informing maintenance personnel of going to the field to examine and maintain by the monitoring center.

Description

Whether a kind of handrail that detects staircase and step synchronous device

Technical field

The utility model relates to a kind of escalator detecting device, particularly a kind of handrail that detects staircase and step synchronous device whether.

Background technology

Electronic Fu ladder generally is tilting, and the pedestrian is automatic step of walking on an end station of staircase, just can automatically be brought to the other end of staircase, and step can one tunnel maintenance level in the way.The Fu ladder is provided with in the both sides with the synchronization-moving handrail of step, holds up for the user and holds.Escalator can be forever to walk to a direction, but majority can be according to needs such as time, the stream of peoples, by operating personal control direction of travel.The problem that existing staircase exists is: the excessive very easily cause danger of automatic staircase handrail band and step running velocity error, so stipulate in the GB of escalator that its synchronism can not surpass 3%.Yet in practice, do not have a good method of measurement.

Summary of the invention

The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and whether synchronous device of a kind of handrail that detects staircase and step is provided, and utilizes waveform, tests the method for its synchronism.Accurate, quick and easy characteristics that this test method has.

Its technical scheme is: the pinch roller rotary encoder of the operating speed of increase checking step on the staircase pinch roller, install to detect handrail rotary encoder and the coder expansion tightening wheel of the operating speed of handrail additional at handrail, wherein, the handrail rotary encoder is installed in the upper surface of handrail, the coder expansion tightening wheel is installed in the lower surface of handrail, the handrail rotary encoder is reliably rotated, detect the synchronous situation of change of pinch roller rotary encoder and handrail rotary encoder, send sound and light alarm when asynchronous, data handler will be reported to the police to monitoring and control centre by the network sending module, and monitoring and control centre notifies the maintainer to go the spot examination maintenance.

Above-mentioned pinch roller rotary encoder and handrail rotary encoder whenever rotate a circle and can produce 2048 pulses or 1024 pulses.

The beneficial effects of the utility model are: it is accurate, quick and easy that this test method has, and when step is asynchronous with handrail, can send sound and light alarm, and can stop the elevator operation, guarantees passenger's safety.

Description of drawings

Accompanying drawing 1 is the structural representation of staircase pinch roller of the present utility model;

Accompanying drawing 2 is structural representations of handrail of the present utility model;

Accompanying drawing 3 is schematic circuit diagram of the present utility model;

Among the upper figure: handrail 1, staircase pinch roller 2, carry 3 more,, pinch roller rotary encoder 4, handrail rotary encoder 5, coder expansion tightening wheel 6.

The specific embodiment

1-3 by reference to the accompanying drawings, the utility model will be further described:

The pinch roller rotary encoder 4 of the operating speed of the utility model increase checking step on staircase pinch roller 2, staircase pinch roller are for 2 times handrail 1, and the handrail below is to carry 3 more; Install to detect handrail rotary encoder 5 and the coder expansion tightening wheel 6 of the operating speed of handrail additional at handrail 1, wherein, handrail rotary encoder 5 is installed in the upper surface of handrail, coder expansion tightening wheel 6 is installed in the lower surface of handrail, the handrail rotary encoder is reliably rotated, by detecting the synchronous situation of change of pinch roller rotary encoder 4 and handrail rotary encoder 5, can send sound and light alarm when asynchronous.

Wherein, pinch roller rotary encoder 4 and handrail rotary encoder 5 whenever rotate a circle and can produce 2048 pulses, or 1024 pulses, be used for calculating accurately the rotating speed of pinch roller and handrail, and can go out diagram of curves by Software on Drawing, surpass 3% if detect synchronism, carry out immediately sound and light alarm, stop the staircase operation, system will report to the police to monitoring and control centre by the network sending module, and monitoring and control centre notifies the maintainer to go the spot examination maintenance.
