There is no at present special magnetic powder inspection instrument for detection of crane hook defectiveness whether, general A, D, E, O type probe all can not be used for detecting the crane hook defective.The method that detects at present the suspension hook defective is: use a wire to be wrapped on crane hook, then magnetic detection, this method poor operability, and time-consuming, bad grasp are carried out in energising.

The utility model content

The purpose of this utility model is to provide a kind of portable crane suspension hook magnetic detecting device, by the main iron core, the termination iron core that coordinate with crane hook root and hook end respectively and be wrapped in coil on main iron core, poor operability, time-consuming problem of taking a lot of work when being used for solving existing equipment crane hook being detected.

The technical scheme in the invention for solving the technical problem is: a kind of portable crane suspension hook magnetic detecting device comprises flexible yoke, main iron core, coil former, coil, termination iron core, UNICOM's iron core, rotating shaft, cable and plug.

Described main iron core be low carbon steel plate make turn chi shape physical components, be " ┌ " shape member, the termination on the long limit of main iron core has the groove that matches with the crane hook root, grow the limit outer cover at main iron core coil former is arranged, described coil former is that the middle part is the insulating part of plectane for right cylinder, both sides, and the coil former middle part has the rectangular opening that cooperatively interacts with main iron core, be wound with coil on the outside surface of coil former column part, described coil is coiled into by enamel insulated round copper wire, the two ends of coil is electrically connected to cable, and the other end of cable is electrically connected to plug;

The side of main iron core minor face end has a rectangular channel, have a through hole perpendicular to rectangular channel, a rotating shaft is inserted in this through hole main iron core and UNICOM's iron core is movably connected, the other end of UNICOM's iron core is connected with the termination iron core, its type of attachment is identical with the connected mode of main iron core with the UNICOM iron core, and the termination iron core other end has the groove that mutually coincide with crane hook hook end;

At main iron core and iron core fluting place, termination, flexible yoke is installed all.

Described coil former is the phenoplast parts.

Described flexible yoke is to mix parts injection molded in the flexible plastic pellet by the fabulous powdery permalloy of magnetic conductivity.

The beneficial effects of the utility model are: by the main iron core, the termination iron core that coordinate with crane hook root and hook end respectively and be wrapped in coil on main iron core, when efficiently solving existing equipment crane hook being detected, poor operability, time-consuming problem of taking a lot of work, improved work efficiency.

Description of drawings

Fig. 1 is 3 d effect graph of the present utility model;

Fig. 2 is front elevation of the present utility model;

In figure: 1 flexible yoke, 2 main iron cores, 3 coil formers, 4 coils, 5 termination iron cores, 6 UNICOM's iron cores, 7 rotating shafts, 8 plugs, 9 cables.

Embodiment

To shown in Figure 2, the utility model comprises flexible yoke 1, main iron core 2, coil former 3, coil 4, termination iron core 5, UNICOM's iron core 6, rotating shaft 7, plug 8, cable 9 as Fig. 1.

Described main iron core 2 turns chi shape physical components for what low carbon steel plate was made, be " ┌ " shape member, have at main iron core 2 long limit one ends the groove that coincide with the crane hook root, in main iron core 2 long limit outer cover, coil former 3 is arranged, described coil former 3 is that right cylinder, both sides are phenoplast spares of plectane for the centre, have the rectangular opening that cooperatively interacts with main iron core 2 at the middle part of coil former 3, column part outside at coil former 3 is provided with the coil 4 that enamel insulated round copper wire is coiled into, the two ends of coil 4 are electrically connected to cable 9, and the other end of cable 9 is electrically connected to plug 8.

At main iron core 2 minor face termination side openings, a rectangular channel is arranged, have a through hole perpendicular to rectangular channel, a rotating shaft 7 is inserted in this through hole main iron core 2 and UNICOM's iron core 6 is movably connected, and the end that described UNICOM iron core 6 coordinates with main iron core 2 is semicircle, and is inserted in above-mentioned rectangular channel.Described termination iron core 5 is connected with the other end of UNICOM iron core 6, and its connected mode and main iron core 2 are identical with the connected mode of UNICOM iron core 6, and the other end termination of termination iron core 5 has the groove that coincide with crane hook hook end.

For the fluting that makes main iron core 2 and termination iron core 5 can closely cooperate from the complex-curved of different crane hooks, fluting place at main iron core 2 and termination iron core 5 is equipped with flexible yoke 1, described flexible yoke 1 is by the fabulous powdery permalloy of magnetic conductivity, mixes soft solid injection molded in the flexible plastic pellet.Permalloy is a kind of than the iron-nickel alloy that higher magnetic permeability is arranged under low-intensity magnetic field, and nickel content at the Rhometal more than 30%, is all single-phase face-centered cubic (γ) structure when room temperature.
