Technical field
The utility model relates to a kind of elevator wire rope displacement measuring device, more particularly, is a kind of traction steel-cable of elevator or the displacement that speed limiter wire rope is in operation and surveying instrument of linear velocity of detecting.
Background technology
The travelling speed of elevator is lift car upstream or downstream speed, is one of most important elevator test item.Because elevator traction wire rope or speed limiter wire rope are connected with car respectively, so can obtain the travelling speed of elevator indirectly through measuring the displacement of traction steel-cable or speed limiter wire rope.The detection method of prior art is following:
1. by " elevator test method " GB/T10059-2009, use tachometer gage record motor speed and be calculated as follows cage operation speed:
In the formula: v-cage operation speed, m/s;
D-traction sheave pitch diameter, mm;
N-surveys motor speed, r/min;
I-traction machine reduction gear ratio;
The i-traction ratio.
2. use elevator speed meter (being commonly called as tachometer gage) to measure; For example use EC-2100 or EC-900 elevator speed meter; The peripheral speed ring (being commonly called as the roller that tests the speed) of velograph is contacted with operating elevator traction wire rope or speed limiter wire rope lightly, can measure the linear velocity of wire rope.
State on the implementation in the detection, measurement mechanism need well contact with tested mechanism, and by the hand-held detecting instrument operation of reviewer, its operant level directly influences accuracy of detection usually; The wearing and tearing of peripheral speed ring and skid and also can cause the detection error.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes prior art, and a kind of novel elevator wire rope displacement measurement mechanism that adopts the optical imagery detection technique is provided.
The utility model is achieved through following technical proposals: the elevator wire rope displacement measuring device is made up of ccd sensor, DSP image processing system, displacement data reception and disposal system, power supply and instrument calibration etc., on instrument calibration, is provided with the angle sheave with grooving; Said ccd sensor and DSP image processing system are made up of optical mouse chip assembly etc.
The utility model is all right: in the member of angle sheave, use the magnetic material manufacturing, angle sheave has magnetic attraction to tested wire rope.Use Agilent laser engine mouse chip in the said optical mouse chip assembly, the spacing of its optical lens to tested wire rope external diameter is set to 2 to 3mm.
Compared with prior art, the beneficial effect of the utility model is: pick-up unit and tested wire rope are realized noncontacting measurement, and easy and simple to handle, accuracy of detection is higher.
