Description
Technical field
The present invention relates to a kind of resin plastic combined recoverable anchor rod, relate to a kind of cover that bonds specifically and adopt that resin composite materials is made, the colliery support anchor rod of the recyclable utilization of Metallic rod, belong to coal mine roadway safety technics supporting field.
Background technology
In recent years, coal mining accident takes place frequently, and exploitation is all paid much attention to safety of coal mines from the country to the place, how to adopt an effective measure, and prevents that the coal mine roadway landslide from being the emphasis of coal mining security protection.At present, in coal mine roadway, generally take the safety support anchor pole to prevent the tunnel landslide, mainly contain several anchor poles such as pipe seam formula, resin formula, cement formula and mechanical swelling type.Wherein resin anchor is big with its anchored force, and dependable performance is extensively adopted by roadway support under the coal mine.But in resin anchor cover, be difficult for removing because the metallic rod body of existing resin anchor is solid, make that metallic rod body is easily on the excavator head in the exploitation process of tunnel, cause the excavator tool damage, reduce problems such as excavator speed, even owing to clash into the generation spark between excavator head and metallic rod body, there is the hidden danger that causes mine lane gas from explosion, influence production efficiency and bring other potential safety hazards, also have some resin anchors, though metallic rod body separates easily with resin anchor cover, but, also form the potential safety hazard of landslide easily because anchor pole self insufficient strength and anchoring strength are not enough.
Summary of the invention
The object of the present invention is to provide a kind of anchored force big, processing performance is good, and labour-saving easy to use resin plastic combined recoverable anchor rod is to overcome the deficiencies in the prior art.
The object of the present invention is achieved like this, it is mainly by Metallic rod (1), pallet (2), clamp nut (3) and bonding cover (4) are formed, wherein: Metallic rod (1) two ends are equipped with screw thread, and Metallic rod (1) tail end is provided with homalocephalus (11), and be connected to pallet (2) and clamp nut (3), Metallic rod (1) head end is provided with ring washer (12), and overlap (4) and be connected with boning by the band wing of interior notes in bonding cover (4) centre bore nut (43) of blocking up, bonding cover (4) head is the pyramid type structure, the forecone of bonding cover (4) is provided with R type screw thread bulge loop (42), and bonding cover (4) shank portion is provided with spiral bulge loop (40) successively, middle part circumference bulge loop (41) and spiral bulge loop (40).
Wherein, bonding cover (4) material formula is:
ABS raw material 100kg
Deca-BDE 7.5kg
Antimony oxide 2.5kg
French chalk 10kg
Ethoxylated amine 1kg
Conductive carbon black color masterbatch 2kg
Stearic acid 2kg
Wherein: R type spiral bulge loop (42) is the right hand helix type.
Wherein: spiral bulge loop (40) is left-handed screw type.
Wherein: middle part circumference bulge loop (41) cross section is an isosceles trapezoid.
The present invention compared with prior art, anchored force is big, processing performance is good, the anchor rod strength height, Metallic rod is recyclable.
Description of drawings
Fig. 1 is a structural principle schematic diagram of the present invention.
Wherein: 1, Metallic rod, 11, homalocephalus, 12, ring washer, 2, pallet, 3, clamp nut, 4, the bonding cover, 40, the spiral bulge loop, 41, middle part circumference bulge loop, 42, R type screw thread bulge loop, 43, the band wing nut of blocking up.
The specific embodiment
The present invention is further described below in conjunction with drawings and Examples:
Referring to accompanying drawing, mainly by Metallic rod 1, pallet 2, clamp nut 3 and bonding cover 4 are formed, Metallic rod 1 two ends are equipped with screw thread, Metallic rod 1 tail end is provided with homalocephalus 11, homalocephalus 11 is used for Metallic rod 1 use of removing stage makeup and costume, this end also is connected with pallet 2 and clamp nut 3, Metallic rod 1 head end overlaps 4 with bonding and is connected by the band wing of interior notes in the bonding cover 4 centre bores nut 43 of blocking up, this end also is provided with ring washer 12, this ring washer 12 is used for reinforced cementitious cover 4 and Metallic rod 1 integral rigidity after fastening, bonding cover 4 heads are the pyramid type structure, wherein the forecone of bonding cover 4 is provided with dextrorotation R type screw thread bulge loop 42, and bonding cover 4 cylinders part is provided with left-handed spiral bulge loop 40 successively, middle part circumference bulge loop 41 and left-handed spiral bulge loop 40.
Wherein, bonding cover 4 plastic materials are a kind of high strength of special formulation, anti-aging, plastic material that the flame-retardant and anti-static performance is good, and its material adopts following prescription:
ABS raw material 100kg
Deca-BDE 7.5kg
Antimony oxide 2.5kg
French chalk 10kg
Ethoxylated amine 1kg
Conductive carbon black color masterbatch 2kg
Stearic acid 2kg
During use, at first Metallic rod 1 and bonding cover 4 are combined into anchor pole, resin anchoring agent is inserted in the anchor hole that has bored then, aiming at the anchoring agent with rock bolt head pushes, because the head of bonding cover 4 is a cone, be easy to the resin anchoring agent squeeze crack, rotating jumbolter again makes anchor pole stir fast the anchoring agent and pushes to the anchor hole bottom direction, this process makes plastic bonding cover 4 realize well-bonded by anchoring agent and anchor hole wall, but Metallic rod 1 can not contact with the anchoring agent, the convenient recovery used, because plastic bonding overlaps 4 tops and is provided with dextrorotation R type screw thread bulge loop 42, can better impel the anchoring agent in anchor hole, to move, plastic bonding is overlapped 4 outer walls and is provided with left-handed spiral bulge loop 40, make and push laborsaving and can increase the mixture homogeneity of anchoring agent, when the anchoring agent moves to middle part circumference bulge loop 41, the anchoring agent that stirs is contacted with the anchor hole wall more uniformly, increase both caking abilities, when the anchoring agent continues when anchor hole pushes, left-handed spiral bulge loop 40 on the bonding cover 4 continues the anchoring agent is stirred, make anchoring agent and coal dust can not form the coal dust musculus cutaneus, thereby make bonding more firm.This set not only reduces the resistance that the workman pushes inward, and has also reduced the labour intensity the when workman operates simultaneously.When the tunnel needs back production,, can easily realize the recycling of Metallic rod 1 and pallet 2 with the homalocephalus 11 of the stubborn Metallic rod 1 of spanner reverse rotation.
Plastic combined recoverable anchor rod proposed by the invention, compare with the binding type anchor pole of similar technology and to have the following advantages: one, bonding cover 4 is owing to adopt the plastic materials of special formulation, and is in light weight, intensity is high, flame-retardant and anti-static, fully realizes to mould the purpose of Dai Gang; Its two, adopt plastic material, feasible and High-efficient Production in batches on the technology; Its three, plastic bonding cover cylindrical adopts the compound mode of spiral bulge loop and the protruding row of straight trough, thereby makes more all even closely knit that the anchoring agent stirs, and makes the adhesion stress raising; Its four, on Metallic rod 1, increase back-up ring 2 structures, the rock bolt head stiffness is strengthened, self intensity reaches optimum efficiency.They are five years old, because plastic bonding cover 4 adopts nut to be connected with Metallic rod 1, and anchoring agent and flyash can not enter the junction, so can be by oppositely screwing Metallic rod 1, reach reclaim Metallic rod 1, pallet 2 is reused, and reduces the roadway support cost, the purpose of economical with materials, improve back production efficient again, avoided the generation of hidden danger, reached safe and efficient.
