Abstract
The utility model relates to a belt joint displacement measuring device for a wire rope core. The belt joint displacement measuring device for a wire rope core is composed of a measuring head which is controlled by a magnet measuring circuit system, a moving guide board which uses the vertical height of the measuring head to regulate bolts and slots and a positioning column of the measuring head, a sliding scale and a testing stand which are fixed on the guide board. The height of the utility model can be determined by leading a fixing bracket to be supported and arranged at the upper or the lower part of a dynamic running belt, so the dynamic measurement can be realized. In addition, the utility model can measure at a surface range of one face of a rubber belt, the resolution is determined by the precision of a measuring scale, and the precision can reach 10 mu m at present. In addition, the utility model has the advantage of simple structure.
Description
The utility model relates to a kind of pick-up unit that prevents Steel cord belt broken belt, particularly steel core joint displacement measuring device.
Steel cord belt movement capacity is strong, is used widely in the bulk cargo transportation, and the per 100～200m of travelling belt is that one section centre couples together in different ways, constitutes transportation system, and the junction is exactly belt lacing, and belt lacing are buried among the rubber.The quality that joint glueds joint has or not in the bulk cargo transportation and exceeds the safety in production that displacement will directly have influence on the belt transportation, and What is more causes personal injury, and before joint is near broken belt, measure then and can in time handle, but existing than effectively detection means is also limited.The general certain hour that adopts carries out regular spot check with cutter at the belt surface indentation, but can't determine the actual displacement of the inner steel core joint of belt.At present, more advanced pick-up unit is that application number is: 91225607.9, on June 17th, 1992, the notification number by Patent Office of People's Republic of China (PRC) bulletin was: the utility model patent that CN2107444 " prevents and treats horizontal broken belt continuous detection apparatus ", this device is installed on the belt conveyor, utilize known robot calculator to handle the rubber conveyer belt joint area elongation change modeling signal of input, the joint area that it is characterized in that rubber conveyer belt is imbedded magnetic material, magneto sensor is settled on the rubber conveyer belt next door, and the output of magneto sensor connects said robot calculator.Restrictive condition is to imbed magnetic material in joint in advance, but magnetic material has the slip possibility, is to survey the steel core displacement indirectly.In addition, it is reported that in November, 91 is in Shanghai, 1081～1084 pages of " second national sensitive element and sensor academic meeting paper collection " that the whole nation sensitive element and Joint Organizing Committee of sensor learned society write, delivered " steel-core rubber belt transportation system trouble-shooter " and introduced a kind of steel-core rubber belt comprehensive monitoring GDJ system, can monitor the fracture of arbitrary steel core in 1.2 meters wide steel-core rubber belts in real time, the dislocation of arbitrary joint and the most common failures such as wearing and tearing of adhesive tape, key is the monitoring sensor of system, form by the U sections core and the field power supply that are wound with elementary secondary coil, monitoring sensor is to the corrosion of steel core, steel rope breaking and wearing and tearing and tape splice state etc. are measured under the adhesive tape normal speed usually, the U sections core of monitoring sensor is positioned over the below of adhesive tape, and the invariable gap of maintenance between tape sensor and the adhesive tape is lived with lifting roll-in in top, sensor both sides.Characteristics are used AC power, and monitoring sensor and permanent magnet place the adhesive tape two sides, and measuring accuracy is limited in practice, the systematic comparison complexity.
It is a kind of directly at the high-resolution measurement mechanism of the joint of any position of steel core that the purpose of this utility model is to provide, and make its system simple.
The purpose of this utility model is to realize like this, design one is by the gauge head of surveying the control of magnetic circuit system, regulate the motion guide plate of bolt and groove with band gauge head vertical height, be fixed in the pick-up unit that gauge head reference column on the guide plate and sliding mark are formed, the gathering sill by the motion guide plate simultaneously detects Steel cord belt lacing displacement measuring device with the testing stand formation of tape guide rail and slide scale and spiral micro actuator at adhesive tape.Gauge head is made of permanent magnetic source and survey magnetic cell.Testing stand is regulated bolt, and motion guide plate, reference column are made with non-magnet material.Survey the magnetic circuit control system, adopt three cover independent DC power supplies, supply with the gauge head power supply respectively, supply with the balancing circuitry system power supply that prior art constitutes, supply with zeroing indication, record, waveform processing power supply that prior art constitutes.Digital display scale Circuits System is self-powered.
The beneficial effects of the utility model are that pick-up unit and testing stand constitute one, gauge head is made of permanent magnetic source and survey magnetic cell, survey magnetic circuit and adopt three cover independent DC power supplies, can carry out transverse and longitudinal detects, directly survey the steel core joint location, but the not tested restriction of counting is detected on the plane, its detection resolution is decided by the scale precision, can reach 10 μ m at present, simple in structure.
