The utility model can simultaneously detect one root or more roots of steel wire ropes, and reach the effect of simplicity and portability, and use effect with high sensitivity.

Description

Wire rope flaw detector

The utility model relates to a kind of harmless flaw detector, particularly is exclusively used in the probe of wire rope flaw detection.

Wire rope is visited detector in the eighties, and the development of existing producer is also produced.It mainly is wearing and tearing and the fracture of wire degree that detects wire rope, but the steel rope flow detector of producing at present, volume is big, carries inconvenience, and probe and wave tracer, complete machine, sound and light alarm instrument all are separately assemblings, connects badly, directly influences the data of detection.Operating, also very trouble, especially probe (sensor) are the critical components of a signal extraction in detecting.The neodymium nickel cobalt (alloy) that material adopts is made magnetic induction part, volume is big, magnetic field intensity is weak, demagnetization is fast.This makes the index that detects wire rope can't be accurate.Because steel rope flow detector mainly is that the big more sensitivity of sensitivity, magnetic field intensity of probe is just high more.Probe can connect multiple execution unit, represents the breakage of wire rope, and as wave mode registering instrument or sound and light alarm instrument etc., the signal that probe is extracted amplifies demonstration, and therefore the quality of probe will directly influence the effect of defectoscope.

The purpose of this utility model is to provide the open and close type probe of several design features, detects one or more wire rope simultaneously and reaches simple, portable, highly sensitive result of use to adapt to.

The purpose of this utility model realizes by following technical measures.

Described probe is by constituting with lower member: outer closure box, bale handle, lock, sleeve pipe, bottom bale handle, magnet steel, hinge, magnet steel web joint; The outer closure box is an open-close type up and down, be provided with lock opening the place's of connecing one side, opposite side is provided with hinge, top is fixed with bale handle, the bottom is fixed with the bottom bale handle, and two sleeve pipes of opening are equipped with at the center of box, and rare earth magnetic steel and magnet steel web joint that four equidimensions are equipped with in the outside of sleeve pipe are solidly installed, in the middle of the bottom sleeve magnetic induction coil is housed, two groups of taps are connected on the accessory power outlet; Bale handle on the probe is the circular arc of dividing right and left respectively; The probe box body is the opening and closing left and right formula, and the box body center is provided with four sleeve pipes.

Advantage of the present utility model and effect are:

1. what its probe adopted is the open and close type structure, is not subjected to the restriction of specification and position when detecting wire rope.

2. Tan Tou magnetic induction part is to adopt the high strength magnetic material, aluminium, iron, boron (rare earth), and therefore the probe size of design is little, and magnetic field intensity is big, and never demagnetization is easy for installation.

3. this probe improves greatly to ability and the scope that detects wire rope, the scope of former detection wire rope is φ 20-φ 50mm, and need with three probes, can detect the various wire rope of φ 6-60 φ mm after now improving, only need a probe, sensitivity has improved 2-3 doubly, and can arrange wire rope more to elevator and detect.

4. whole defectoscope has made up wave tracer and acoustooptic alarm system, and is provided with power of alterating and direct current, with probe have after linking to each other volume little, in light weight, easy to carry, be not subjected to characteristics such as operating infulence.

Fig. 2 is the utility model probe component left view;

Fig. 3 is the structural representation of another embodiment of the utility model probe component;

Fig. 4 is the structural representation of the another embodiment of the utility model probe component;

Fig. 5 is the utility model control assembly synoptic diagram.

Below in conjunction with the accompanying drawing illustrated embodiment, the utility model is done further detailed description:

As shown in Figure 1, the sleeve pipe 4 of folding up and down is equipped with in the horizontal center of outer closure box 1, for the purpose of wear-resisting, the material of this sleeve pipe 4 can select for use nylon to make, and the aluminium of identical size, iron, boron are equipped with in the outside of sleeve pipe, and promptly rare earth magnetic steel 7, be connected on the web joint 10, in the middle of the bottom sleeve 7 inductive coil is housed, links to each other, after forming closed high-strength magnet ring coils induction, export to the execution display with accessory power outlet 6.Bale handle 2 is equipped with on the top of box, and bottom bale handle 5 is equipped with in the bottom, in order that convenient when carrying or operating, a side of box body is provided with hinge 8, and opposite side is provided with cracks formula lock 3 between the teeth.

Embodiment 2: probe as shown in Figure 3 is the opening and closing left and right formula, and bale handle 2 is circular-arc, is more convenient for like this carrying and operating.The probe of this structure, the main dedicated probe that is fit to the detection wirerope diameter in the following specification of 20mm.

Embodiment 3: probe as shown in Figure 4 also is the opening and closing left and right formula, and the center of box can be provided with a plurality of sleeve pipes, is four as elevator wire rope, can establish four sleeve pipes, can detect four wire rope simultaneously.

Fig. 5 is the controller synoptic diagram, during use, connects power lead and probe wire, turns on the power switch 11, and pilot lamp 12 is bright, and gain potentiometer 13 is transferred to centre position (gain that turns clockwise increases, and inhour rotation gain reduces).Pull out the paper feed switch 15 on the wave tracer 14, recording chart begins to walk out, and this explanation instrument is normal, turns off the registering instrument switch then.Probe lock 3 opened be enclosed within on the tested wire rope, lock then, wire rope is pulled out registering instrument paper feed switch 15 simultaneously with the speed operation of 2mm-2m/s, can detect.Before detecting wire rope, the very important person is the sample rope for making a defective wire rope, and this instrument is calibrated.(the sample rope is identical with detected wire rope model specification).The state peak value of damaged wire rope be will on waveform paper, clearly show like this, thereby the damaged condition and the position of wire rope found.
