Abstract
The utility model discloses a forepole bar for driving face anchor bolt support, which is applicable to the top surface supporting of coal mine lanes or tunnels. The forepole bar is composed of an upper connecting plate and a lower connecting plate connected with each other by a connecting shaft, a sliding hole is arranged on the upper connecting plate, an anchor bolt is mounted in the sliding hole, a cushion block and a nut are arranged on the lower end of the anchor bolt, and a long beam is mounted between the lower connecting plate and the connecting shaft. The utility model mainly overcomes the defects that an anchor bolt is directly mounted with a pallet or a circular ring with iron tube for the top surface supporting of coal mine lanes or tunnels, the contact surface of the anchor bolt and the top surface is small and stones are easy to fall off. When in use, the contact surface of the forepole bar and the top surface is increased, stones are prevented from falling, the safety is improved, and the forepole bar also has the characteristics of simple mounting, firmness, reliability, good safety and feasibility.
Description
Technical field the utility model relates to a kind of driving face bolt support forestope, is used for coal mine roadway or tunnel roof supporting.
Background technology is present, people are in coal mine roadway or tunnel roof supporting, most adopt traditional anchor pole is hammered into the top in tunnel or tunnel after, then pallet directly is contained in the anchor pole pop-up and holds out against admittedly, also having a kind of is at anchor pole lower end clamping rings, the dress iron pipe is with the purpose of the end face supporting that reaches in the ring, above-mentioned any suspension device no matter all exists with the end face contact surface for a short time, and whole mask do not become whole, cause to prevent that roof fall falling rocks safety factor is little, casualty accident etc. easily takes place.
Utility model content the purpose of this utility model provides a kind of driving face bolt support forestope for people exactly, and the end face that is installed in coal mine roadway or tunnel increases and the expansion contact surface, prevents the danger of roof fall falling rocks effectively.
The purpose of this utility model is to realize by following technique measures:
Comprise anchor pole, go up lower connecting plate and long beam composition, it is that upper junction plate passes the two with lower connecting plate by connecting axle and links to each other, one end of axle has steady pin, the other end is that static line ties up on lower connecting plate and the cushion block, the upper junction plate end face has sliding eye, skyhook in this hole, and the lower end of bar is equipped with cushion block and is contacted with the upper junction plate face, nut is arranged below the cushion block, long beam is installed between lower connecting plate and connecting axle.
Sliding eye on the described upper junction plate is rectangle, and cushion block is slightly larger than the sliding eye width.
Advantage of the present utility model: compared with prior art, be to link to each other by upper and lower junction plate to load onto long beam, be fixed on the anchor pole that contacting with tunnel and tunnel roof increases and enlarged contact surface with cushion block, nut, prevent the roof fall falling rocks, improved safety factor.Install simple, solid and reliable, easily capable safely.
Description of drawings elaborates to the utility model below with reference to accompanying drawing:
Fig. 1 is the main schematic diagram of looking of the utility model assembling.
Fig. 2 is that schematic diagram is looked on the utility model Fig. 1 right side.
Fig. 3 is the utility model Fig. 1 schematic top plan view.
The specific embodiment comprises anchor pole 7, upper junction plate 1, lower connecting plate 4 and long beam 9 compositions by shown in Fig. 1-3.The two is passed upper junction plate 1 and lower connecting plate 4 by connecting axle 3 and links to each other, connecting axle 3 one ends have steady pin 2 lock shafts, make the upper and lower junction plate 1,4 can left and right slippage, the other end is that static line 8 ties up on lower connecting plate 4 and the cushion block 5, be difficult for losing when making each component-assembled or disassemble, upper junction plate 1 end face has rectangular sliding eye 10, anchor pole 7 is housed in the hole, the cushion block 5 that is slightly larger than sliding eye 10 width is equipped with in the lower end of bar, and contact with 1 of upper junction plate, there is nut 6 to tighten below the cushion block 5, the long beam 9 of dress between lower connecting plate 4 and connecting axle 3.
During installation, anchor pole 7 is hammered into earlier on tunnel or the tunnel roof, load onto upper junction plate 1 and hold and nut 6 is tightened, longer beam 9 is placed on the lower connecting plate 4, penetrate upper and lower junction plate 1,4 two ends with connecting axle 3 and connect dress together by cushion block 5.
