Description
Technical field
The utility model belongs to technical field of mine support.Prevent anchor cable from breaking the security protection of injection more particularly to a kind of
Device.
Background technique
Currently, cable bolting can not only improve roadway support effect as a kind of economical and effective drift support type
Fruit reduces roadway support cost, and is conducive to quickly propelling for coal work and improves with coal production.Cable bolting has become
Coal in China and other mine workings be preferred, safe and efficient main support pattern.The equipment of mine support mainly by anchor cable,
The composition such as anchorage, aligning ball pad and supporting plate；Anchor cable is generally with having the steel strand wires of certain elasticity to be made, its main feature is that multiplying loading capability
Height can apply biggish pretightning force, can get more satisfactory volume supporting effect, be a kind of current most reliable, most effective means.
After anchor cable stirring anchoring, upper pallet, aligning ball pad, lockset are successively installed and carry out tensioning preload work.
There are many common anchor rope supporting plate type of mine support, and China's prestressed concrete member, ground anchorage process are extensive
Using flat planker and arch supporting plate.Anchor cable is fixed on by such supporting plate at the aperture of the drilling of mine support.But due to
In roadway support, anchor cable needs to bear biggish pretightning force, needs particularly with the anchor cable with high-strength prestress by opening
Preload is stretched to reach more high-prestressed.Therefore, when the pressure of greater impact formula occurs in tunnel, anchor cable bearing capacity is easy to cause to reach
To itself limit, there is a phenomenon where break.When breaking, the part that powerful impact force can make anchor cable exposed has huge
Energy.Since existing supporting plate does not have the structure and function for drawing off such energy, the anchor cable to break can be from the anchor cable on supporting plate
It is projected at high speed in hole, seriously threatens life security.
Part Coal Mine temporarily uses plastic bushing and rubber casing to place anchor cable as protective device and breaks injection at present,
Its intensity is obviously inadequate, cannot play real security protection effect.Therefore, it is necessary to one kind can prevent anchor cable height when breaking
Rapid fire goes out, the safety guards for avoiding casualty accident from occurring.
Summary of the invention
Aiming at the deficiencies in the prior art, the utility model provides a kind of roadway support anchor cable and snaps security protection
Device can effectively prevent anchor cable high speed when breaking from projecting, avoid the generation of casualty accident.
For above-mentioned purpose, technical solutions of the utility model are as follows:
A kind of roadway support anchor cable snaps safety guards, including cylinder-shaped sleeve, the stainless steel wire for fixing anchor cable
Fixed pendant and rubber sleeve shield, the cylinder-shaped sleeve are equipped with ring flange mouth, uniformly open that there are four fixed on the ring flange mouth
Circular hole；The fixed pendant of the stainless steel wire sequentially passes through the fixation of the anchor net and cylindrical shroud pipe flange mouth of anchor rope supporting plate two sides
On circular hole, the fixed pendant of stainless steel wire is fixed with lock union.
Further, the cylinder-shaped sleeve is used for the anchor cable to lock outside anchor cable hole.
Further, the cylinder-shaped sleeve lower part is cased with rubber sheath, for preventing metallic weapon outer from scratching operation
Personnel, rubber sheath bottom-thickened 10mm can be to lower part equipment and personnel if the reasons such as misoperation cause protector to fall off
It plays a protective role.
The utility model has the advantages that the utility model is structurally reasonable, easy to operate, safety protector and anchor cable, lockset and anchor cable support
Plate connects into an entirety, and in the online secondary fixed protection of roadway support anchor, realization sheds anchor cable when anchor cable breaks
The upper most strength that breaks, can effectively prevent anchor cable from projecting or break anchor at a high speed out of anchor cable hole and fall off, peace with higher
Full protection effect avoids the generation of casualty accident.Rubber sheath can effectively prevent metallic weapon outer to scrape in the utility model
Hurt operating personnel, if the reasons such as misoperation cause protector to fall off, buffer protection work can be played to lower part equipment and personnel
With.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the working condition of the utility model.
Fig. 2 is the ring flange mouth of the utility model and its structural schematic diagram of cylinder-shaped sleeve.
Fig. 3 is the closed loop schematic diagram of the fixed pendant of stainless steel wire of the utility model.
Specific embodiment
Illustrate the utility model referring to specific embodiment.It will be appreciated by those skilled in the art that these are implemented
Example is merely to illustrate the utility model, does not limit the scope of the utility model in any way.
A kind of roadway support anchor cable snaps safety guards, as shown in Figure 1, including the anchor cable that set is fixed in outside locking anchor cable hole
1 cylinder-shaped sleeve 6, the fixed pendant 5 of stainless steel wire and rubber sleeve shield 7；7 sets of rubber sheath, in 6 lower part of cylinder-shaped sleeve, are used for
Prevent metallic weapon outer from scratching lower part operating personnel, in this implementation, 7 bottom-thickened 10mm of rubber sheath, if misoperation
Etc. reasons cause protector to fall off, buffer protection function can be played to lower part equipment and personnel.
As shown in Fig. 2, cylinder-shaped sleeve 6 is equipped with ring flange mouth 61, uniformly open that there are four fixed circular holes 62 on Pan Kou；In conjunction with
Fig. 1, the fixed pendant 5 of stainless steel wire is all 4, each sequentially passes through the anchor net 3 and cylinder-shaped sleeve 6 of 2 two sides of anchor rope supporting plate
On the fixation circular hole 62 of ring flange mouth 61, the fixed pendant 5 of stainless steel wire is fixed with lock union 51, so that rubber will be cased with
The cylinder-shaped sleeve 6 of set shield 7 links together with anchor cable 2, the lockset 4 of anchor cable and anchor rope supporting plate 2, forms rock-steady structure.This reality
It applies in example, 6 internal diameter of cylinder-shaped sleeve is 25mm, wall thickness 3mm, whole high 90mm；61 diameter of ring flange mouth is 51mm, fixed circular hole
62 diameters are 5mm, the long 7.5mm of 6 inner wall of distance of center circle cylinder-shaped sleeve of fixed circular hole 62.It is placed on the rubber sleeve of cylinder-shaped sleeve 6
Protecting 7 internal diameters is 31mm, wall thickness 2mm, whole high 72mm；Wherein bottom-thickened 10mm.
As shown in figure 3, the fixed pendant 5 of stainless steel wire can directly will by setting screw thread in lock 51 both ends open of union
The fixed pendant of stainless steel wire screws tight, formation circular closed loop, and in the present embodiment, it is 2mm, length that the fixed pendant of stainless steel wire, which is diameter,
For the stainless steel wirerope of 680.8mm, the circular closed loop of diameter about 110mm can be formed.
The above content is the detailed descriptions for combining optimal technical scheme to do the utility model, and it cannot be said that utility model
Specific implementation be only limitted to these, for made under the premise of not departing from the utility model thought it is simple deduction and replacement, all
It should be considered as the protection scope of the utility model.
