Nondestructive measuring instrument for thickness of covering rubber layer of steel wire lining conveyer belt and measuring method thereof

Abstract

The invention relates to a nondestructive measuring instrument for the thickness of a covering rubber layer of a steel wire lining conveyer belt and a measuring method of the nondestructive measuring instrument. The nondestructive measuring instrument for the thickness of the covering rubber layer of the steel wire lining conveyer belt comprises a base, a power source, an adjusting lead screw, a stand column, an induction limiting stopper and a displacement measurer used for measuring the moving distance of the induction limiting stopper. The stand column is vertically arranged on the base, the adjusting lead screw is connected with a threaded hole in the stand column, the lower end of the adjusting lead screw is fixedly connected with the induction limiting stopper through a connecting rod, the induction limiting stopper is suspended on the side edge of the base and electrically connected with the power source, and the displacement measurer is fixedly connected with the stand column through a fixing frame. According to the measuring instrument, after a probe of the induction limiting stopper makes contact with the working face of the steel wire lining conveyer belt and induces steel wires, the adjusting lead screw is rotated to make the probe of the induction limiting stopper slowly move upwards until the probe does not induce the steel wires, the moving distance of the probe can be known through the displacement measurer, and the thickness of the covering rubber layer is known through calculation.

Description

technical field [0001] The invention relates to a thickness measuring instrument, in particular to a non-destructive measuring instrument and a measuring method for the thickness of a rubber layer covered by a steel wire-lined conveyor belt. Background technique [0002] The steel wire lined conveyor belt has the advantages of high tensile strength and good impact resistance, and is widely used in the transfer and transportation of bulk materials in ports and mines. During the use of the conveyor belt, the thickness of the rubber covered on the steel wire-lined conveyor belt will gradually be worn due to friction. Timely control of the critical point of the thickness of the covered rubber layer and taking corresponding measures are important measures to maintain stable production. [0003] At present, the following two methods are mainly used to measure the thickness of the rubber layer of the steel wire-lined conveyor belt. The first one is acupuncture. See figure 1 , us...

Problems solved by technology

During the use of this method, although the thickness measurement is more accurate, it will bring some damage to the conveyor belt 3 and it is not suitable to carry out it many times.

In order to improve the accuracy of the measurement data, the conveyor belt 3 with a length of more than 200 meters needs to measure multiple points in sections. The exposed steel wire 31 will be corroded soon after the rainwater seeps in, and the water will seep in along the axial direction of the steel wire 31, seriously It affects the adhesion between the steel wire 31 and the conveyor belt 3, and brings great potential safety hazards to the subsequent use of the conveyor belt 3

[0005] There are certain defects in the above-mentioned methods of measuring the thickness of the rubber layer of the steel wire-lined conveyor belt. Therefore, it is still waiting for people to develop a non-destructive measuring instrument for the thickness of the rubber layer of the steel wire-lined conveyor belt that has high measurement accuracy and will not damage the conveyor belt. One of the technical problems, at the same time, a set of measurement methods for the above-mentioned measuring instrument is required, which can make the detection have better results
