The triangular support leg has the advantages that the triangular support leg is mainly applied to a bracket of the miniature drilling machine for the rock bolts of various overhead power transmission lines, and the stable construction and drilling of the miniature drilling machine for a rock bolt foundation are guaranteed.
Description
Technical field
The present invention relates to a kind of transmission line construction aid, particularly relate to a kind of transmission line of electricity rock bolt small-sized drill Multifunctional triangle type leg.
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 overhead transmission line rock bolt small-sized drill Multifunctional triangle type leg, solve the problem that the middle-size and small-size rig bracket stability of existing construction technology can not meet quality requirement.
Technical scheme of the present invention is as follows:
Comprise triangular plate, dish nail, the fixing pincers of plug and connecting ring; The bottom surface setting dish nail of triangular plate, triangular plate is provided with through hole, and the fixing pincers of plug are through through hole, and the top of triangular plate is provided with connecting ring, and three limits of triangular plate are provided with folded sheet, and folded sheet is provided with auxiliary through hole, and the fixing pincers of auxiliary plug are through auxiliary through hole.
Described triangular plate is equilateral triangle.
Between described dish nail, interval is equal, and dish nail length is identical.
Between described through hole and plug are fixed and are clamped; Auxiliary through hole is flexibly connected by screw thread between clamping with auxiliary plug is fixing.
Described through hole internal diameter is identical with auxiliary through hole internal diameter size.
Described triangular plate is connected by folding is folding with between folded sheet.
Advantageous effect of the present invention is as follows;
1, drilling machine construction is easy to operate, flexible, and cost is low, produces easy.
2, due to three tips of Multifunctional triangle type leg, dish nail and can the fixing pincers of plug, can highly stable embedding rock mass top layer, make small-sized drill bracket stable sexual satisfaction quality requirement.
3, triangular plate is equilateral triangle, and after embedding rock mass, each limit is firm.
4, between dish nail, interval is equal, and dish nail length is identical, after embedding rock mass, ensure that whole machine balancing and steadiness.
5, through hole and plug are fixing clamp between screw thread is flexibly connected, be convenient for carrying, and use flexible, can according to job location difference, choice for use or do not use and use plug to fix the quantity of pincers.
6, through hole internal diameter is identical with auxiliary through hole internal diameter size, reduces costs, without the need to carrying the fixing pincers of plurality of specifications plug, easy to operate.
7, triangular plate three limit arranges folded sheet, can according to Specific construction situation, adjusting triangle dish size, and the used time can not fold and pack up, and opens during use, and folded sheet is agreed to arrange auxiliary through hole and the fixing pincers of auxiliary plug, enhances steadiness.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of triangular plate.
In figure, 1, triangular plate, 2, through hole, 3, connecting ring, 4, dish nail, 5, the fixing pincers of plug, 6, folded sheet, 7, auxiliary through hole.
Detailed description of the invention
Referring to accompanying drawing, in conjunction with specific embodiments, concrete structure of the present invention is described in detail.
Embodiment
As shown in Figure 1, comprise triangular plate 1, pincers 5 and connecting ring 3 are fixed in dish nail 4, plug; Triangular plate is equilateral triangle, the bottom surface setting dish nail 4 of triangular plate, and between dish nail, interval is equal, and dish nail length is identical, and triangular plate is provided with through hole 2, and plug fixes pincers 5 through through hole, and through hole is flexibly connected by screw thread between clamping with plug is fixing; The top of triangular plate is provided with connecting ring 3, and three limits of triangular plate connect folded sheet 6 by folding is folding, and folded sheet is provided with auxiliary through hole 7, and the fixing pincers of auxiliary plug are through auxiliary through hole; Auxiliary through hole is flexibly connected by screw thread between clamping with auxiliary plug is fixing.
Described through hole internal diameter is identical with auxiliary through hole internal diameter size.
When transmission line of electricity rock bolt small-sized drill is constructed on the rock of mountain area, small-sized drill Multifunctional triangle type leg inserts rock surface, and be connected with the oblique fulcrum bar of drill stand of drill, due to three tips of triangular form leg, dish nail and can the fixing pincers of plug, can highly stable embedding rock mass top layer, effectively can absorb the construction of Rock Bolt Foundation small-sized drill and creep into vibration force, ensure that drill hole of drilling machine diameter and verticality meet quality criteria requirements.Can plug fix pincers can according to landform, geological conditions, rig feature choosing, in order to strengthen fixed effect.
Through the real model experiment in twice three places in February, 2014 to June, test 6 test specimens altogether.Compare with other small-sized drill leg, rig can be shortened and creep into the duration 30%, reduce investment outlay 15 ~ 20%.
