Embodiment
For further setting forth the utility model for the technological means reaching predetermined utility model object and take and effect, below in conjunction with accompanying drawing and preferred embodiment, to according to its embodiment of the special demagnetizer of a kind of steel wire rope, structure, the method that the utility model proposes, be described in detail as follows.
Refer to Fig. 1 to Fig. 3, the utility model provides a kind of steel wire rope special demagnetizer, includes: shell, and top casing 2 is set to stepped, and two sides shell 8 bottom has arch through hole, and this top casing 2 is orthogonal with two sides shell 8 to be connected; Side plate 1, this top casing 2 is provided with side plate 1 in two ends in addition; Support bar 7, this two sides shell 8 inside is provided with support bar 7, and this support bar 7 is orthogonal with side plate 1 to be connected; Residual magnetization checkout gear 6, in the inside of top casing 2 bossing; Anti-magnetized coil, in the enclosure, this anti-magnetized coil is provided with the coil 4 of U-shaped iron core 3 and enamelled wire coiling, and this U-shaped iron core 3 is through the coil 4 of this enamelled wire coiling; And lining 5, below anti-magnetized coil.
This shell, support bar 1, side plate 1 are made of aluminum.This side plate 1 top is set to handle shapes.This residual magnetization checkout gear 6 is provided with the LED showing the residual magnetization detected, is shown the residual magnetization detected by 9 LED light.On the skeleton that this coil 4 makes around epoxy plate, this coil rack is hollow, and this U-shaped iron core 3 is bonded through this coil rack by two parts in the middle part of this coil rack, and it forms magnetic boots at outer two end faces of coil 4 and be arc surface.This lining 5 is made up of nylon material.
