Abstract
The invention relates to a chassis of a drilling machine for a rock bolt on an electric transmission line. The chassis comprises a cross arm and a bracket, wherein the bracket is arranged vertical to the cross arm; the bracket is composed of two support beams and a support rod, the two support beams are arranged in parallel, one end of each of the two support beams arranged in parallel is fixed on the cross arm, and the support rod is connected between the other ends of the two support beams; a drill pipe support chassis is arranged above the bracket, and a drill pipe support is fixed on the chassis. The chassis is mainly applied to various small drilling machines for the rock bolt on the electric transmission line, is simple and convenient to produce and manufacture and low in cost, and can guarantee that the small drilling machine for a rock bolt foundation is convenient and flexible for transportation and construction.
Description
Technical field
The present invention relates to a kind of transmission line construction auxiliary equipment, particularly relate to a kind of transmission line of electricity rock bolt borer chassis, be 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.
Summary of the invention
The present invention is directed to Problems existing in the construction of transmission line of electricity Rock Bolt Foundation small-sized drill, provide a kind of transmission line of electricity rock bolt borer chassis, when solving drill hole of drilling machine in existing construction technology, the problem of poor stability, constructional difficulties.
Technical scheme of the present invention 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 support bar, and two brace summers be arranged in parallel, and the one end of two brace summers be arranged in parallel is fixed on cross-arm, connects support bar between the other end of two brace summers; The top of bracket arranges drill rod rack chassis, and drill rod rack is fixed on chassis.
Described cross-arm is arranged row's cross-arm screwed hole.
Described cross-arm screwed hole spacing is 10cm.
One end that described brace summer is connected with cross-arm arranges brace summer screwed hole, and brace summer screwed hole and cross-arm screwed hole match, bolt through brace summer screwed hole and cross-arm screwed hole fastening.
Described support bar is telescopic loop bar.
Arrange gusset plate between described brace summer and cross-arm, gusset plate, brace summer and cross-arm form triangle.
Described gusset plate is fixed by bolt screw and brace summer and cross-arm, and gusset plate screwed hole and cross-arm screwed hole match.
Described brace summer is provided with the restraint zone of fastening rig.
Advantageous effect of the present invention is as follows:
1, brace summer, support bar and cross-arm form sweet font steel bracket, and borer chassis constructing operation is convenient, flexibly, cost is lower, produces easy.
2, by the support of sweet font steel bracket and drill rod rack, effectively ensure that the stability that drill hole of drilling machine is constructed, meet bore dia and the verticality quality requirement of rock bolt small-sized drill drilling construction.
3, cross-arm is arranged row's cross-arm screwed hole, brace summer can be fixed on different screwed holes as required, thus effective spacing.
4, support bar is telescopic loop bar, can regulate the length of support bar, easy to use and flexible according to brace summer spacing.
5, between brace summer and cross-arm, gusset plate is set, enhances the steadiness of bracket.
6, 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.

Detailed description of the invention
Embodiment
As shown in Figure 1, comprise cross-arm 1 and bracket, bracket is vertical with cross-arm to be arranged; Bracket is made up of two brace summers 2 and support bar 3, and two brace summers be arranged in parallel, cross-arm is arranged row's cross-arm screwed hole, and adjacent cross-arm screwed hole spacing is 10cm; One end that described brace summer is connected with cross-arm arranges brace summer screwed hole, and brace summer screwed hole and cross-arm screwed hole match, bolt through brace summer screwed hole and cross-arm screwed hole fastening; Arrange gusset plate 8 between described brace summer and cross-arm, gusset plate 8, brace summer 2 and cross-arm 1 form triangle; Gusset plate is fixed by bolt screw and brace summer and cross-arm, and gusset plate screwed hole and cross-arm screwed hole match.Connect support bar 3 between the other end of two brace summers 2, support bar is telescopic loop bar; 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, 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, connect and compose sweet font bracket by two channel-section steel bolts to carry on a shoulder pole on cross-arm, drill rod rack is fixed on sweet font bracket, with bolt or fixation with steel wire, by the support of sweet font bracket and drill rod rack, effectively ensure that the stability of rig on 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 29%, reduce investment outlay 14 ~ 18%.
