Abstract

The utility model discloses a steel rope flaw detector which comprises a sensing device. The sensing device is composed of a semi-circle annular upper guiding sleeve and a semi-circle annular lower guiding sleeve in a matching mode. A magnetic tape controller (MTC) magnetic sensor is respectively installed in each guiding sleeve. The upper guiding sleeve is provided with a handle. A guiding wheel which is provided with a photoelectric encoder is connected with the handle in a movable mode through a connecting rod. A spring is arranged between the connecting rod and a transverse rod of the handle. The MTC magnetic sensors and the photoelectric encoder are connected with a mobile radio communication (MRC) real-time alarm and a computer in series through signal lines. The steel rope flaw detector is a nondestructive testing instrument based on a principle of magnet leakage. The steel rope flaw detector solves the problem that existing manual check is not reliable, and thus has the advantages of being convenient to operate, accurate in detection and capable of effectively eliminating potential safety hazard.

Description

Steel rope flow detector

Technical field

The utility model relates to a kind of steel wire nondestructive detection device, is specifically related to a kind of steel rope flow detector.

Background technology

Wire rope is to be twisted thigh by the multilayer steel wire, centered by wire rope core, twists with the fingers helically wound rope by some thighs again.In material carrying machine, for promote, traction, tension and carrying.Along with continuing of service time, various damage phenomenons will appear in wire rope.For example, because steel wire wear and corrosion cause long-pending the reducing of section of steel wire; Because the variation tired, that harden in the surface, corrosion causes the steel wire internal performance; Use improper distortion that causes rope etc.Single line fracture, burn into wearing and tearing, random line equivalent damage may occur at the labour wire rope, various damages all will cause the fault of wire rope.Because importance and construction of wire rope characteristic of property that wire rope uses, after major defect appearred in a place in the wire rope, whole wire rope will be scrapped, and therefore, in a single day wire rope breaks down and will be unrepairable.At present, wire rope depends on hand inspection mostly at the degree of injury of use procedure, or scraps by pressure tenure of use, and is both unreliable, might cause waste again.

Summary of the invention

Technical problem to be solved in the utility model provide a kind of easy to operate, detect accurate steel rope flow detector.

For solving the problems of the technologies described above, the technical scheme that the utility model steel rope flow detector adopts is: it comprises sensing device, described sensing device is made of upper guide bush and the cooperation of lower guide pin bushing of semicircle annular, the MTC Magnetic Sensor all is installed in each guide pin bushing, upper guide bush is provided with handle, the guide wheel that is provided with photoelectric encoder is flexibly connected by connecting rod and handle, be provided with spring between the cross bar of connecting rod and handle, described MTC Magnetic Sensor and photoelectric encoder are connected with MRC Realtime Alerts device and computing machine by signal wire.

Because technique scheme adopts the guide pin bushing that the MTC Magnetic Sensor is installed, when wire rope to be measured produced relative motion through guide pin bushing, the MTC Magnetic Sensor was finished the axial magnetized of wire rope and collection signal, every operation one circle of guide wheel, photoelectric encoder sends the sampling command pulse, realizes spatial domain sampling.MRC Realtime Alerts device transmits the data-signal of changing by signal wire and stores in the computing machine, utilizes simultaneously the online in real time Treatment Analysis of power of the CPU of computing machine, sends the Realtime Alerts signal according to the equivalent threshold value that sets in advance.Therefore, the utility model is a kind of nondestructive detecting instrument based on magnetic flux leakage theory, has solved the insecure problem of existing hand inspection, have easy to operate, detect accurate characteristics, effectively eliminated potential safety hazard.
