Abstract
The invention relates to a displacement measuring device for a wire rope of an elevator. An optical mouse chip component is applied to form a displacement detecting system of an optical image. A guide wheel with a rope groove is arranged on a meter rack; and a member of the guide wheel is made of magnetic materials. The guide wheel has magnetic attraction to the wire rope to be measured so that regulated mutual positions of the measuring device and the wire rope to be measured can be kept and contactless displacement measurement is realized. The displacement measuring device is suitable for measuring the operation speed and the travel of the elevator, and has the advantages of simple operation and higher detection accuracy.
Description
Technical field
The present invention 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 measuring instrument of linear velocity of detecting.
Background technology
The running velocity of elevator is lift car upstream or downstream speed, is one of most important elevator test item.Because elevator traction steel rope or speed limiter wire rope are connected with car respectively, so can obtain the running velocity of elevator indirectly through measuring the displacement of traction steel-cable or speed limiter wire rope.The method of inspection of prior art is following:
1. by " elevator test method " GB/T10059-2009, use speed 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-towing machine reduction ratio;
The i-traction ratio.
2. use elevator speed meter (being commonly called as speed 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 speed gauge is contacted with operating elevator traction steel rope or speed limiter wire rope lightly, can measure the linear velocity of steel 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 inspector, 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 objective of the invention is to overcome the deficiency of prior art, a kind of novel elevator wire rope displacement measurement mechanism that adopts the optical imagery detection technique is provided.
The present invention 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 track adjusting wheel with grooving; Said ccd sensor and DSP image processing system are made up of optical mouse chip assembly etc.
The present invention is all right: in the member of track adjusting wheel, use the magnetic material manufacturing, track adjusting wheel has magnetic attraction to tested steel rope.Use Agilent laser engine mouse chip in the said optical mouse chip assembly, the spacing of its optical lens to tested steel rope external diameter is set to 2 to 3mm.
Compared with prior art, the invention has the beneficial effects as follows: detecting device and tested steel rope are realized noncontacting measurement, and easy and simple to handle, accuracy of detection is higher.
