Description

A kind of replacing mine hoisting rope anti-wrap device

Technical field

The utility model relates to a kind of more changing device of multi-rope friction hoist hoisting rope, particularly relates to a kind of replacing mine hoisting rope anti-wrap device.

Background technology

In underground mining process, multi-rope friction hoist is used for from down-hole to aboveground lifting ore, personnel or material.Multi-rope friction hoist is generally with 6 rope hoistings, in replacing lifting ropes of multi-rope process, in order to guarantee that lifting container (skip bucket or cage) does not fall into shaft bottom, be all generally to extract out after 2 or 3 old hoisting ropes simultaneously, then put 2 to 3 new hoisting ropes in pit shaft.

The problem existing is: when changing the long hoisting rope of hundreds of rice, while being entangled on reel for rope due to new steel rope, exist a kind of centripetal force, while putting rope, need " broken strength ", therefore easily cause between the hoisting rope of newly putting and be mutually wound around, or the hoisting rope of newly putting is wrapped on old hoisting rope, more changed jobs and brought great difficulty.

Common terms of settlement is, finds that transferring steel rope is wound around mutually at certain degree of depth position, must to this level place, manually break strength by row personnel steel rope is separated, and safety factor is low, and labour intensity is large.

Summary of the invention

The purpose of this utility model is to provide a kind of replacing mine hoisting rope anti-wrap device, by transferring steel cord ends and installing the mode of the broken strength device of hoisting rope inhibiting device and counterweight, make it the broken strength in Fang Sheng limit, limit, solve the replacing difficult problem that in frictional geared replacing lifting ropes of multi-rope process, the mutual winding between hoisting rope brings, make to transfer steel rope everything goes well with your work and carry out, improve and change hoisting rope efficiency, reduce processing time and labour intensity that while changing hoisting rope, generation is wound around.

The purpose of this utility model realizes by following technical proposals: a kind of replacing mine hoisting rope anti-wrap device, it is characterized in that by hoisting rope inhibiting device and the broken strength installation composition of counterweight, described hoisting rope inhibiting device comprises two iron plates, is welded between two iron plates and diameter is greater than the annulus of hoisting rope diameter; The broken strength device of described counterweight comprises two symmetric parts and is bolted fixing, wherein each symmetric part is welded with semicircle gear by blocking rope device, card rope device comprises a square iron prop, ear in the welding of square iron prop both sides with bolt hole, the front of square iron prop, with radius, be less than hoisting rope radius mode and carry out turning, form a circular-arc groove; Semicircle gear comprises a smaller part round iron plate, at circular arc consistent with the circular-arc groove of square iron prop of its string center turning.

Each described annulus is comprised of two semicircular ring of correspondence, and the iron plate being welded on respectively is separately upper, and the two ends of every iron plate are provided with bolt hole and by bolt, two iron plates are connected and fixed.Described annulus is 2～6.

Compared with the prior art, the utility model has solved in hoisting rope decentralization process winding problem mutually conscientiously, in hoisting rope automatically broken strength in decentralization process, is not mutually wound around again, makes to put rope work simple.The utility model has reduced the wearing and tearing of new rope, has improved safety factor, has improved the operating efficiency of maintenance, has shortened the replacing hoisting rope time more than 24 hours simultaneously.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in Fig. 1～5, a kind of replacing mine hoisting rope anti-wrap device is comprised of the broken strength device 13 of hoisting rope inhibiting device 12 and counterweight, described hoisting rope inhibiting device 12 comprises two iron plates 1, be welded between two iron plates 1 and diameter is greater than the annulus of hoisting rope 10 diameters, number of rings is two to six, each annulus is comprised of two semicircular ring 2 of correspondence, and be welded on respectively on iron plate 1 separately, the two ends of every iron plate are provided with bolt hole 3 and by bolt 5, two iron plates 1 are connected and fixed to (referring to Fig. 1,2).The broken strength device 13 of described counterweight comprises two symmetric parts and is connected and fixed by bolt 5, wherein each symmetric part is welded with semicircle gear 7 by blocking rope device, card rope device comprises a square iron prop 9, ear 6 in square iron prop 9 both sides welding with bolt hole 3, the front of square iron prop 9, with radius, be less than hoisting rope 10 radius modes and carry out turning, form a circular-arc groove 8; Semicircle gear 7 comprises a smaller part round iron plate, at circular arc consistent with the circular-arc groove 8 of square iron prop of its string center turning.Semicircle gear 7, square iron prop 9 and two ear 6 three parts integrally welded (referring to Fig. 3,4).

Referring to Fig. 5, a kind of method of using above-mentioned replacing mine hoisting rope anti-wrap device, when hoisting rope 10 is put new hoisting rope by lifting drum 11 to down-hole, the annulus by hoisting rope 10 through inhibiting device; Open the bolt 5 of the broken strength device 13 of counterweight, make the semicircle gear 7 of the broken strength device 13 of counterweight upward, when fag end was inserted to the broken strength device 400-500mm of counterweight place, tight a bolt 5, stuck steel cable head.When the annulus of inhibiting device is comprised of two semicircular ring 2 of correspondence, at hoisting rope 10, through before inhibiting device, fixing with bolt 5 after two iron plate consistencies from top to bottom that are welded with semicircular ring 2 are aimed at, both sides are welded with welding iron plate 4 again.After the broken strength device 13 of hoisting rope inhibiting device 12 and counterweight installs, under the effect that hoisting rope 10 pulls down at the broken strength device 13 of counterweight, under the position-limiting action of hoisting rope inhibiting device 12, every new hoisting rope is all in position separately, transfer on one side, the broken strength of rotation on one side, has solved the broken strength problem of winding in hoisting rope decentralization process.
