Abstract
The utility model discloses the safety device that a kind of anti-anchor cable lock launches, comprise anchor cable, anchor cable is provided with lockset, be provided with buffering compression-member at lockset to anchor cable tail end near lockset, described buffering compression-member is fixed on auxiliary anchor pole.Compared with prior art, the utility model advantage has: 1. the utility model applies certain axial compression by the length shortening the shellproof flexible net between two auxiliary anchor poles to buffering stage clip and makes it be in compressive state, first the instantaneous impact produced when the lockset of anchor cable launches acts on buffering stage clip, buffering stage clip relies on self shrinkage strain under the restriction of pressure-bearing iron pallet and shellproof flexible net, absorb and consume most of impact energy, the casualty accident that can successfully prevent from lockset from launching causing; 2. the utility model alleviates anchor cable lock and launches the potential safety hazard brought, have safe and reliable, cyclic utilization rate is high, be convenient to dismounting, the advantage such as practical.
Description
Technical field
The utility model belongs to mine safety protector, particularly relates to the safety device that a kind of anti-anchor cable lock launches.
Background technology
Anchor cable is widely used in China's coal-mine industry with the advantage of its uniqueness, particularly especially applicable in soft-rock tunnel or the high stress tunnel that affects by dynamic pressure, but, because its environment for use is more severe, often the phenomenon that anchor cable lock launches in lane is there is in practical application, serious personal injury is produced to operating personnel, becomes a major hidden danger of Safety of Coal Mine Production.At present; the device that what down-hole was commonly used prevent anchor cable lock from launching has shellproof sleeve etc.; even indivedual mine is that the steel strand of anchor cable end directly split and bending is chrysanthemum shape by the material-saving that saves time; but the enormous impact power that anchor cable lock produces when moving back anchor acts directly on shellproof sleeve or anchor cable self; therebetween without buffering energy-consumption facility, very easily cause the damage of protector and lose protection effect.
Utility model content
In order to overcome the deficiencies in the prior art, the safety device that the utility model provides a kind of anti-anchor cable lock to launch, adds buffering energy-consumption facility, has pressure release power consumption effect, strengthens protection effect, available protecting protector.
For achieving the above object, be originally that utility model adopts following technical scheme:
The safety device that anti-anchor cable lock launches, comprises anchor cable, anchor cable is provided with lockset, is provided with buffering compression-member at lockset to anchor cable tail end near lockset, and described buffering compression-member is fixed on auxiliary anchor pole.
Described buffering compression-member comprises and is set in lockset successively to the buffering stage clip of anchor cable tail end, pressure-bearing iron pallet and shellproof flexible net, described shellproof flexible net is fixed on auxiliary anchor pole end by anchor rod pallet board and nut centered by anchor cable, by pressure-bearing iron pallet, the enormous impact power that lockset ejection instantaneous produces is passed to whole shellproof flexible net, avoid at certain a bit stressed concentrated.
The free height a of described buffering stage clip is not less than 100mm, establishes enough buffer gaps for rigging launches to stay, and consumes most of impact energy by the shrinkage strain cushioning stage clip.
Described shellproof flexible net is mining high-strength polyester fibers flexible net, by regulating the length of shellproof flexible net that buffering stage clip is applied to certain axial compression and makes it be in forced compression state, avoids buffering compression-member to lose protection effect because of structural relaxation.
Anchor cable pallet is provided with between described lockset and anchor cable fixed body.
In the utility model, pressure-bearing iron pallet specification is consistent with anchor cable pallet, and the length c that anchor cable tail end exposes shellproof flexible net is not less than 100mm; Shellproof flexible net two ends diagonal position is fixed on auxiliary anchor pole end by anchor rod pallet board and nut, and wherein nut is greater than 0 to the distance d of anchor pole end.
Compared with prior art, the utility model has following advantage: 1. the shellproof flexible net of the utility model is fixed on auxiliary anchor pole end by anchor rod pallet board and nut centered by anchor cable, applying certain axial compression by the length shortening the shellproof flexible net between two auxiliary anchor poles to buffering stage clip makes it be in compressive state, first the instantaneous impact produced when the lockset of such target anchor cable launches acts on buffering stage clip, buffering stage clip relies on self shrinkage strain under the restriction of pressure-bearing iron pallet and shellproof flexible net, absorb and consume most of impact energy, the casualty accident that can successfully prevent from lockset from launching causing, 2. the utility model improves the safety factor that cable bolting uses at complex conditions such as soft-rock tunnel and the high stress tunnels that affects by dynamic pressure, alleviate anchor cable lock and launch the potential safety hazard brought, have safe and reliable, cyclic utilization rate is high, be convenient to dismounting, the advantage such as practical.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described:
As depicted in figs. 1 and 2, the safety device that the anti-anchor cable lock of the present embodiment launches, comprise anchor cable 7, anchor cable is provided with lockset 6, buffering compression-member is provided with to anchor cable tail end near lockset at lockset, this buffering compression-member comprises and is set in lockset successively to the buffering stage clip 3 of anchor cable tail end, pressure-bearing iron pallet 4 and shellproof flexible net 5, the free height a of described buffering stage clip is 100mm, and in described buffering compression-member, shellproof flexible net is fixed on auxiliary anchor pole 2 end by anchor rod pallet board 8 and nut 9 centered by anchor cable.
As preferably, the shellproof flexible net of the present embodiment is mining high-strength polyester fibers flexible net.
As further preferably, between the present embodiment lockset and anchor cable fixed body, be provided with anchor cable pallet 1.
As shown in Figure 3, the using method of the present embodiment is as follows:
(1) first, need fixing one end to be arranged in rock mass 10 anchor cable, need locking place that anchor cable pallet is installed at anchor cable, then lockset is installed; (2) at lockset to anchor cable tail end (other end) near lockset successively sheathed buffering stage clip, pressure-bearing iron pallet and shellproof flexible net, shellproof flexible net is fixed on auxiliary anchor pole end by anchor rod pallet board and nut by (3) centered by anchor cable.
