Separator, cover shape separator centre, which is equipped with, accommodates the circular hole that anchor cable passes through, and separator is matched with square thread under conical sleeve.
The ear shape symmetrical configuration, which is arranged, is integrated casting, shape set in conical sleeve two sides, conical sleeve and ear shape structure
The taper aperture of cylinder, upper end aperture are greater than anchor cable diameter 3-10mm, and lower end aperture is matched with intermediate plate.
The separator be lid-like forge piece, lid-like center be provided with the matched through-hole of anchor cable, and separate
The through-hole of device is overlapped with the conical sleeve aperture center of circle, and the through-hole of separator is 3-10mm bigger than anchor cable diameter；Lid-like is circle
Or the distressed structure excessively for facilitating tool to fasten.
The intermediate plate is dovetail slip structure, and outer diameter is matched with conical sleeve center opening, and the intermediate plate is 2~3
Structure fastens conical sleeve on anchor cable by tightening separator.
A kind of application method of the dedicated gripper of coal mine, its step are as follows:
It puts first by conical sleeve is counter, then 2-3 intermediate plate is packed into conical sleeve, separator is screwed on, intermediate plate 7 is made to exist
Conical sleeve 1 forms loose but does not fall off state, and then the positive conical sleeve of separator of screwing on is from mounted anchor cable bottom
Portion is nested on anchor cable upwards, exposes anchor cable anchor head not less than 50mm, separator is tightened applied force, is made in conical sleeve
Intermediate plate and anchor cable fasten；Shackle is installed in the ear shape structure of conical sleeve, and lifting rope is installed between shackle, carries out lifting work
Industry；After the completion of lifting, shackle and lifting rope are removed；Separator is firmly backed out, taps conical sleeve upwards until intermediate plate loosens
Conical sleeve is disassembled from anchor cable.
The utility model has the advantages that
The gripper of the design is convenient for disassembly and assembly reusable, save the cost；Gripper own wt is light, installation and dismounting
Convenient, construction efficiency is high；Intermediate plate has a safety feature without the danger to fall off；
Conical sleeve and monosymmetric ear shape structure are cast member, and there is taper aperture at conical sleeve center, and cast member holds
It is easy to produce, it is at low cost.Separator is forge piece, and center is provided with conical through-hole, and is overlapped with the separator center opening center of circle, forging
Part good toughness, intensity is big, not easy to break；
Wherein intermediate plate is dovetail slip structure, and outer diameter is matched with a center opening is hung, and locking is simple, is not easy to pull, and is pacified
