Description
Technical field
The utility model relates to a kind of transmission line construction auxiliary equipment, particularly relates to a kind of rock bolt borer chassis, is mainly used in various transmission line of electricity rock bolt small-sized drill drilling construction.
Background technology
Transmission line of electricity adopts Rock Bolt Foundation, can save raw materials consumption, reduce construction costs, avoid heavy excavation, corresponding environmental issue that great explosion or digging foundation bring, reaches the object of engineering environmental protection, joint consumption, has important economy and social effect.Study widely although rock bolt technology at home and abroad has, getting more and more in recent years is applied on power transmission line iron tower foundation.But because domestic and international existing anchor bolt construction plant equipment is heavier, volume is large, is difficult to be applicable to mountain region transport and install, although therefore anchor rod foundation has good economic benefit and social benefit, is also difficult to promote on a large scale in transmission line of electricity always.Key lacks the miniaturization rock bolt drilling equipment that can adapt to the complicated terrain environments such as mountain area; Small-sized drill of the prior art is in physical features cliffy mountain drilling construction difficulty, large mainly due to borer chassis weight, and mountain area ground wire is complicated, cannot ensure rig stability, thus the bore dia of impact construction and verticality.
Utility model content
The utility model, for Problems existing in the construction of transmission line of electricity Rock Bolt Foundation small-sized drill, provides a kind of rock bolt borer chassis, when solving drill hole of drilling machine in existing construction technology, and the problem of poor stability, constructional difficulties.
The technical solution of the utility model is as follows:
Comprise cross-arm and bracket, bracket is vertical with cross-arm to be arranged; Bracket is made up of two brace summers, and two brace summers be arranged in parallel, and the both sides of brace summer connect folded sheet, and brace summer is provided with the restraint zone of fastening rig; The top of bracket arranges drill rod rack chassis, and drill rod rack is fixed on chassis.
Described bracket welds with cross-arm.
Arrange gusset plate between described brace summer and cross-arm, gusset plate, brace summer and cross-arm form triangle.
Described gusset plate and brace summer and cross-arm are welded and fixed.
Described folded sheet is connected with brace summer by folding.
The utility model has the advantages of as follows:
1, bracket and cross-arm support borer chassis, and borer chassis constructing operation is convenient, flexibly, cost is lower, produces easy, effectively ensure that the stability that drill hole of drilling machine is constructed, and meets bore dia and the verticality quality requirement of rock bolt small-sized drill drilling construction.
2, brace summer both sides arrange folded sheet, folded sheet can be opened during work, increase Area of bearing, during end-of-job, receive to brace summer, save folding for folded sheet space, be easy to carry.
3, between brace summer and cross-arm, gusset plate is set, enhances the steadiness of bracket.
4, brace summer is provided with the restraint zone of fastening rig, ensure that the stability of rig, thus ensures that construction is effectively carried out.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is bracket cross-arm plan structure schematic diagram of the present utility model.
In figure, 1, cross-arm, 2, brace summer, 3, folded sheet, 4, chassis, 5, drill rod rack, 6, drilling rod, 7, near coal-mine, 8, gusset plate.
Detailed description of the invention
Embodiment
As shown in Figure 1-2, comprise cross-arm 1 and bracket, bracket and cross-arm vertical welding; Bracket is made up of two brace summers 2, and two brace summers be arranged in parallel, and the both sides of brace summer 2 connect folded sheet 3, and folded sheet is connected with brace summer by folding; Reinforcement of weld plate 8 between brace summer 2 and cross-arm 1, gusset plate, brace summer and cross-arm form triangle; Brace summer is provided with the restraint zone of fastening rig; The top of bracket arranges drill rod rack chassis 4, and drill rod rack 5 is fixed on chassis.
When transmission line of electricity rock bolt small-sized drill is constructed on the rock of mountain area, channel-section steel cross-arm load is on the construction of transmission line of electricity Rock Bolt Foundation is near coal-mine, as the spandrel girder bearing rig weight, form wood bracket by two square long wood to carry on a shoulder pole on cross-arm, borer drill rod stentplacement is on flexible wood bracket, fixing by steel wire flexibility, due to wood bracket and borer drill rod bracket base contact area larger, add the support of borer drill rod support, effectively ensure that the stability of borer drill rod stentplacement on wood bracket, meet bore dia and the verticality quality requirement of rock bolt small-sized drill drilling construction.
Through the real model experiment in twice two places, test 3 test specimens altogether.Compare with other small-sized drill bracket, rig can be shortened and creep into the duration 35%, reduce investment outlay 17 ~ 21%.
