Description
Technical field
The present invention relates to a kind of ground connection hammer drills suitable for winter assembly and disassembly ground line.
Background technique
The Northeast's winter can generate frozen soil layer, and soil property becomes abnormal hard, distribution operation (power transmission work containing part) dress
During dismounting ground wire, existing ground connection hammer drill, which is difficult to install, to be more difficult to pull out, and also often occurs making a mess of or even scrapping ground connection hammer drill
The phenomenon that.
Chinese Patent Application No. 201420462776.0 discloses a kind of ground connection hammer drill structure for being not easy loosening and conveniently pulling up,
The intensity of ground connection hammer drill is increased to a certain degree, hand steered structure is arranged in top, and it is more convenient to pull up, but in the Northeast's winter
It is season, extremely difficult by hand to extract ground connection hammer drill even if there is hand steered structure on frozen soil since drill pole is cylindrical structure.To jelly
It drills a blasting hole in soil, usually using sledgehammer, dynamics control does not with great difficulty bend hammer drill or coup injury ground wire terminal plate, very
It is grounded to damage, lacks whether in place mark is unfavorable for detection ground connection hammer drill.
Summary of the invention
In order to overcome the deficiencies of the prior art, the object of the present invention is to provide a kind of ground connection suitable for winter assembly and disassembly ground line
Whether hammer drill has the advantages that facilitate embedment, pull out convenient for rising, while being embedded to convenient for observation ground connection hammer drill in the construction process
Position avoids ground line from causing to damage due to embedded ground connection hammer drill.
To achieve the above object, the invention is realized by the following technical scheme:
A kind of ground connection hammer drill suitable for winter assembly and disassembly ground line, including drill steel, pricker point, handrail, drill steel and pricker point are one
Body structure, pricker point are conical structure, and handrail is welded at the top of drill steel, and the handrail is isosceles triangle, and drill steel top is stretched
The waist on the bottom edge of isosceles triangle out, handrail offers mounting hole；Drill steel bottom end extends to form pricker point, and drill steel is equipped with mark
Line；Drill steel is regular prism structure or drill steel is up big and down small truncated cone-shaped structure.
The drill steel is hexagonal prisms structure.
The marking line bottom to drill steel bottom end is 600mm.
The pricker point surface is equipped with quenching layer.
The mounting hole is two, and a mounting hole is circle, another mounting hole is oblong.
The handrail is bent to form isosceles triangle by round steel.
Compared with prior art, the beneficial effects of the present invention are:
Ground connection hammer drill suitable for winter assembly and disassembly ground line is structurally reasonable, production easy to process.Isosceles triangle handrail, i.e.,
It protects manpower safety to increase sledgehammer focusing surface again, handrail is stretched out on drill steel top, resistance to the beating property of ground connection hammer drill can be increased.Drill steel
Using regular prism or frustum cone structure, ground connection hammer drill easily can be extracted into frozen soil.Marking line is set on drill steel, convenient for safety prison
It examines, effectively identification buried depth.Pricker point enhances penetration power using quenching mode.Handrail is bent into horizontal abduction structure in vertex,
It can play the role of protective ground wire, prevent sledgehammer exertin, drill steel embedment is too deep, the connection of damage ground line and ground connection hammer drill
Place.

Specific embodiment
The present invention is described in detail with reference to the accompanying drawings of the specification, it should be noted that implementation of the invention is unlimited
In the following embodiments and the accompanying drawings.
See Fig. 1, Fig. 2, a kind of ground connection hammer drill suitable for winter assembly and disassembly ground line, including drill steel 1, pricker point 3, handrail 2, pricker
Bar 1 is structure as a whole with pricker point 3, and pricker point 3 is conical structure, and handrail 2 is welded on 1 top of drill steel, and the handrail 2 is isosceles
The bottom edge of isosceles triangle is stretched out on triangle, 1 top of drill steel, and the waist of handrail 2 offers mounting hole 5；1 bottom end of drill steel extends to form
Pricker point 3, drill steel 1 are equipped with tag line 4, when tag line 4 is concordant with native face or can't see tag line 4 with regard to stopping operation of drilling a blasting hole, side
Construction, effectively identify buried depth convenient for safety monitor；Drill steel 1 is regular prism structure or drill steel 1 is up big and down small rotary table
Shape structure, is shown in Fig. 2.See Fig. 1, Fig. 3, if drill steel 1 be hexagonal prisms structure, rise pull out ground connection hammer drill when, first positive and negative rotation handrail 2 each 30
Degree, makes gap occur between drill steel 1 and frozen soil, so that drill steel 1 is entered ground space and becomes larger, convenient for pulling up.Drill steel 1 is up big and down small circle
The power although the more cylindrical embedment of drill steel 1 frozen soil of platform shape structure need to add some points, the laborsaving side of cone space can be made full use of when pulling out by rising
Just.
3 surfaces of pricker point are equipped with quenching layer, then zinc-plated after quenching, increase the intensity of ground connection hammer drill, enhance penetration power.Mark
Line bottom to 1 bottom end of drill steel is 600mm, meets ground connection hammer drill embedment and requires.See Fig. 4, the handrail 2 being arranged at mounting hole 5 is flat
Face structure increases the contact area with ground line；Mounting hole 5 is two, and a mounting hole 5 is circle, another mounting hole 5 is
Oblong, to facilitate adjustment ground line installation site.Handrail 2 is bent to form isosceles triangle by round steel, and hand is facilitated to enter handrail 2
It exerts a force in the delthyrium formed with drill steel 1, and symmetrical beautiful.
It is grounded hammer drill and uses high strength steel material, such as: 45# steel, the hardness of enhancing ground connection hammer drill itself.It is whole to be grounded hammer drill
Surface is zinc-plated, antirust, enhances durability.
Ground connection hammer drill suitable for winter assembly and disassembly ground line is structurally reasonable, and production easy to process facilitates winter northeast and applies
Work.Isosceles triangle handrail 2, i.e. protection manpower safety increase sledgehammer focusing surface again, and handrail 2 is stretched out on 1 top of drill steel, can be increased
It is grounded resistance to the beating property of hammer drill.Drill steel 1 uses regular prism or frustum cone structure, especially hexagonal prisms structure, can be easily by ground connection
Hammer drill extracts frozen soil.It adds whether tag line 4 is embedded in place convenient for observation ground connection hammer drill on drill steel 1, is convenient for safety monitor.Pricker
Point 3 enhances penetration power using quenching mode.Handrail 2 is bent into horizontal abduction structure in vertex, can play protective ground wire
Effect, prevent sledgehammer exertin, drill steel 1 is embedded to too deep, the junction of damage ground line and ground connection hammer drill.
