Abstract
The utility model relates to an anchor mesh (rope) support of a coal mine underground tunnel, in particular to an anchor rope breakage ejection-preventive protection device, which solves the problem that ejection of a broken anchor rope of a coal mine underground anchor mesh (rope) support causes personnel casualty accidents. The anchor rope breakage ejection-preventive protection device comprises a steel pipe capable of being sleeved on an exposed end of an anchor rope of a tunnel inner anchor mesh (rope) support and used for supporting an anchor rope lock, at least two iron chains or steel wire ropes are fixedly evenly distributed at one end of the steel pipe via connectors, and hooks fixed onto free ends of the iron chains or steel wire ropes via connectors are capable of being suspended on beams, or W steel bands, or metal mesh sheets of an ejector plate anchor rod ladder near the tunnel inner anchor mesh (rope) support in a hooked manner. The anchor rope breakage ejection-preventive protection device has the advantages of simple and reasonable structure, fine utilization effect, safety, reliability, high practicality, reusability, and capabilities of effectively preventing casualty accidents caused by anchor rope breakage and providing guarantee for personal safety for underground employees.
Description
Technical field
The utility model relates to anchor net (rope) supporting of colliery underworkings; specifically be a kind of high-strength prestress anchor cable that uses when colliery underworkings anchor net (rope) supporting when being subjected to suddenly fracture taking place under the effect of geological structure stress, can avoid anchor cable to penetrate the anti-protective device of penetrating of anchor cable fracture that the accident that causes casualties takes place.
Background technology
Along with the reform of mine support technology, colliery tunnel support has experienced wooden support, has built the arch supporting, the shaped steel supporting is to the very long process of anchor net (rope) supporting.Anchor net (rope) supporting belongs to " active support ", can in time reinforce country rock, reduces surrouding rock deformation, prevent the early stage absciss layer of top board, and have and simplify the face end supporting, reduce support cost, reduce characteristics such as labor strength, thereby, be widely used as the agent technology of mine support.Yet, we find in anchor net (rope) supporting practice, when crossing the geological structure band or being subjected to mining influence, anchor cable can rupture because of the effect that is subjected to tensile force and shearing force, the anchor cable of fracture is under the elastic stress effect, can fly away moment, bring very big threat for the life safety of underground operators.
Summary of the invention
The utility model penetrates the problem that the accident that causes casualties takes place when rupturing for the anchor cable that solves colliery underworkings anchor net (rope) supporting, provides a kind of anchor cable fracture the anti-protective device of penetrating.
The utility model is to adopt following technical scheme to realize: the anti-protective device of penetrating of anchor cable fracture; comprise that the anchor cable that can be placed in anchor net (rope) supporting in the tunnel exposes the steel pipe that the end is used to hold the anchor cable lockset; steel pipe one end is by uniform at least two iron chains or the wire rope of being fixed with of connector, and the free end of iron chains or wire rope is fixed with by connector and can be hooked in the tunnel near the roofbolt ladder beam anchor net (rope) supporting anchorage cable or on the W steel band or the hook on the wire lath sheet.
During use, the anchor cable that steel pipe is placed in anchor net (rope) supporting in the tunnel exposes the end, and make a end that steel pipe is fixed with iron chains or wire rope inwardly, then iron chains or the free-ended hook of wire rope are hooked in the tunnel near the roofbolt ladder beam anchor net (rope) supporting anchorage cable or get final product on the W steel band or on the wire lath sheet, after wherein requiring to install, the state of iron chains or wire rope is in the nature hang, promptly non-tensioned state.
Like this; when anchor net (rope) supporting anchorage cable because when being subjected to the effect of geological structure stress under taking place suddenly moment fracture release elasticity kinetic energy and flying out; because the buffering and the constraint of protective device described in the utility model are arranged; limited the outer displacement space of penetrating the anchor cable part; effectively stoped anchor cable, pallet and the lockset etc. of fracture to fly away together; thereby eliminated potential safety hazard, avoided the generation of anchor cable casualty accident.
Compared with prior art; the utility model not only can prevent the generation of anchor cable fracture ejaculation casualty accident; can also serve as warning simultaneously; when the iron chains of protective device described in the utility model or wire rope change tensioned state into by natural hang; show that locating the corresponding anchor cable of protective device described in the utility model with this ruptures; remind the personnel in the pit in time to take to strengthen supporting measure, prevent roof collapse.
The utility model is simple and reasonable for structure, and result of use is good, and is safe and reliable, practical, and cost is low, can reuse; Can effectively prevent the generation of anchor cable fracture casualty accident, for down-hole worker's life safety provides guarantee.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: the 1-steel pipe; The 2-wire rope; The 3-hook; 4,5-connector.
The specific embodiment
As shown in Figure 1; the anti-protective device of penetrating of anchor cable fracture; comprise that the anchor cable that can be placed in anchor net (rope) supporting in the tunnel exposes the steel pipe 1 that the end is used to hold the anchor cable lockset; steel pipe 1 one ends are by connector 5 uniform at least two iron chains or the wire rope 2 of being fixed with, and the free end of iron chains or wire rope 2 is fixed with by connector 4 and can be hooked in the tunnel near the roofbolt ladder beam anchor net (rope) supporting anchorage cable or on the W steel band or the hook 3 on the wire lath sheet.
During concrete enforcement, the diameter of the specification of steel pipe 1, the visual anchor cable of size is adjusted voluntarily; The size of iron chains or wire rope 2 does not limit, the kinetic energy when requiring to have enough intensity and can bear anchor cable and penetrate and not rupturing; Connector 4 between the connector 5 that iron chains or wire rope 2 and steel pipe are 1, iron chains or wire rope 2 and hook can adopt multiple structure to realize, as long as can guarantee to be connected firmly.
The utility model mainly is applicable to the getting working face that uses anchor cable to add strong supporting.In tunneling process; when running into geological structure band, soft unstable country rock, compound roof work plane, fender driving face and being subjected to the driving face of mining influence; because above-mentioned headwork surface pressure is big; the tectonic stress complexity; absciss layer takes place in top board easily; anchor cable takes place easily to rupture to penetrate and hurts sb.'s feelings under various pulling force and shearing force effect; so when driving, must use the anti-protective device of penetrating of anchor cable fracture described in the utility model; so just can eliminate accident in bud, accomplish obviate.Must use the anti-protective device of penetrating of anchor cable fracture described in the utility model in stope two crossheading advance support sections in addition; because stope advance support section abutment pressure is very big; under the cycle pressure effect, the part anchor cable is along with crushing and factor affecting such as discontinuity equalization is easy to fracture and penetrates.
