Abstract
The utility model relates to an anchor cable end protecting bush and solves the problem that fractured anchor cables hurt people during the process of coal mining on island working faces. The anchor cable end protecting bush is composed of a protection cover plate, a protection sleeve, tensioning steel wires and fixing iron hooks, wherein the protection sleeve is vertically fixed at a center position of the protection cover plate, a plurality of through holes are evenly distributed around the protection sleeve on the protection cover plate, the tensioning steel wires respectively penetrate through the through holes on the protection cover plate to be fixedly wound on the protection cover plate, and ends of the tensioning steel wires are fixedly connected with the fixing iron hooks. During usage, a user inserts an anchor cable end into the protection sleeve, tensions the tensioning steel wires which are fixedly wound on the protection cover plate towards the periphery of the protection cover plate and finally hangs the fixing hooks onto a supporting iron net. The anchor cable end protecting bush has the advantages of being simple in structure, reasonable in design, low in manufacturing costs, convenient to use, good in protection effects, recyclable and capable of effectively preventing the fractured anchor cables from hurting human bodies to achieve the purpose of safe production in coal mines.
Description
Technical field
The utility model relates to mine laneway cable bolting technical field, specifically is that the operation of isolated island work plane influences a kind of anchor cable end protective cover in the deathtrap.
Background technology
Pass soft stratum or slide plane by boring; In hard rock stratum, (call anchor head) to an end (anchor pole) rivet clasp; Carry out stretch-draw at another free end (anchor head outside claiming) then; Thereby the rock stratum exerted pressure unstable rock mass is carried out anchoring, this method is claimed prestress anchorage cable, is called for short anchor cable.The isolated island work plane, as the term suggests be exactly work plane both sides or around be the goaf, exploitation be in the middle of the coal seam left over.When the fully mechanized coal face of mine is the isolated island face, in the process of mining, the big imagination that surpasses people of roof pressure.In order to guarantee the normal operation of this ore deposit fully mechanized coal face; Before coal mining, at first all can carry out prestressed anchor reinforcement, still to the top board and the coal group of work plane; In the coal mining process still the phenomenon that anchor cable ruptures because of can't bear the heavy load can appear; Can produce transient acceleration after the anchor cable fracture and eject, casualty accident happens occasionally, and has had a strong impact on the safety in production in colliery.
Summary of the invention
The purpose of the utility model is for fear of the generation at isolated island work plane coal mining process stream line fracture back casualty accident, reaching the purpose of safety in production, and a kind of anchor cable end protective cover is provided.
The utility model is realized through following technical scheme:
A kind of anchor cable end protective cover; By protective cover plate, protection tube, tensioning steel wire and fixedly cleek form; Wherein, protection tube is vertically fixed on the center of protective cover plate, is evenly equipped with some through holes around protection tube on the protective cover plate; Every tensioning steel wire passes the back around admittedly on protective cover plate the through hole from protective cover plate respectively, is connected with fixedly cleek on the termination of each tensioning steel wire.
During use; With the anchor cable head of protection tube sleeve outside being exposed to the rock stratum; Be to arrange and tensioning radially in the center with the protective cover plate with each tensioning steel wire then, will be fixed in fixedly cleek on each tensioning steel wire end at last and block a break iron that is suspended in the tunnel respectively and get final product on the net.After anchor cable was because of the fracture that can't bear the heavy load, this anchor cable end protective cover left a bit stroke and produces acceleration moment ejaculation for the anchor cable of fracture in the hole, let this anchor cable end protective cover bring into play the personal safety of tight protective action with the protection personnel.
Further, be evenly equipped with the even number through hole around protection tube on the protective cover plate, and intert around solid tensioning steel wire in every two relative through holes.The benefit that is provided with like this is that when producing acceleration moment ejaculation when the anchor cable fracture, the anchor cable fracture impact force that whole anchor cable end protective cover receives is more balanced, makes the anchor cable end protective cover play safer protective action.
Protective cover plate is circular steel plate, and protection tube is a coating steel pipe, and the tensioning steel wire is a zinc-coated wire.Protective cover plate adopts circular steel plate, and steel matter has strengthened the force intensity that receives of protective cover plate on the one hand, adopts circular design can avoid personnel's extension in the course of the work to hinder on the other hand, thereby reduces the probability of injury to personnel; Protection tube adopts coating steel pipe, and it all is to receive force intensity in order to strengthen it that the tensioning steel wire adopts zinc-coated wire, and its safeguard function is improved further.
Be the safeguard protection degree of this anchor cable end protective cover of Precision Test, specialize corresponding anchor cable is stressed breaks test and check the security performance of this anchor cable end protective cover.Show through tight test: after the anchor cable pressurized that does not add this anchor cable end protective cover was broken, the anchor cable of the fracture rice that can fly out surplus in the of 10 was far away; After the anchor cable pressurized of " wearing " last this anchor cable end protective cover was broken, under the pressure of the prevention dynamics of this anchor cable end protective cover, the anchor cable of its fracture was firmly entangled by this anchor cable end protective cover, thereby reduced the probability of injury to personnel, reached the purpose of safety in production.
The utlity model has simple in structure, reasonable in design, cost of manufacture is low, easy to use, protection effect good, advantage such as recyclable, the injury that can avoid anchor cable fracture back that human body is produced effectively, thus reach the purpose of Safety of Coal Mine Production.

Fig. 3 is the right view of Fig. 1.
Among the figure: 1-protective cover plate, 2-protection tube, 3-tensioning steel wire, 4-be cleek, 5-through hole fixedly.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done to describe further (following examples are illustrative, the utility model are not done any qualification):
A kind of anchor cable end protective cover; By protective cover plate 1, protection tube 2, tensioning steel wire 3 and fixedly cleek 4 form; Wherein, protection tube 2 is vertically fixed on the center of protective cover plate 1, is evenly equipped with some through holes 5 around protection tube 2 on the protective cover plate 1; Every tensioning steel wire 3 passes the back around admittedly on protective cover plate 1 through hole from protective cover plate 15 respectively, is connected with fixedly cleek 4 on the termination of each tensioning steel wire 3.
When the present embodiment practical implementation; It is that 100mm, thickness are the circular steel plate of 6mm that protective cover plate 1 adopts a diameter; It is the coating steel pipe that 26.5mm, length reach 100mm that protection tube 2 adopts a diameter; Around protection tube 2 through hole 5 that to be evenly equipped with four diameters be 11mm, and in every two relative through holes 5, intert around solid tensioning steel wire 3 on the protective cover plate 1, it is that 6mm, length are the zinc-coated wire of 1200mm that tensioning steel wire 3 adopts diameters; The affixed respectively fixing cleek 4 in four terminations of tensioning steel wire 3; Fixedly to adopt diameters be the serpentine cleek of 8mm for cleek 4, and for guaranteed strength, fixedly cleek 4 behind bending forming, also to through forging, reinforcing operation such as quenching.
