Description

Power equipment is with boring stake

Technical field

This utility model is related to power construction technical field, and specifically a kind of power equipment is with boring stake.

Background technology

Going deep into further with power construction, power construction project substantially increases, and in Power Project construction, has and much sets Standby needs are realized fixing using boring stake, using fixtures such as steel wire tow lines, by power equipment fixed strain, for raising power equipment Fixing strong degree is therefore, to assure that bore the reliability of stake and stratum attachment, it is to avoid bores stake and pulls out from stratum.However, it is existing Bore stake during practice of construction, when brill stake starts to install, be difficult to screw in, even if after brill stake screws in, soil layer is easy to loosen, Reduce and bore the pulling force that pile is subject to, bore stake when actual installation screws in and screws out construction, waste time and energy.

Utility model content

The purpose of this utility model is to provide a kind of power equipment to bore stake, conveniently will bore stake and screw in and screw out.

This utility model solves technical problem and adopts the following technical scheme that

With boring stake, including drill bit, postpone in one end of drill bit has drilling rod to power equipment, and one end of described drill bit is arranged to bore Shape, being extended positioned at the conehead end outer wall of drill bit has flight, and described flight is straight along the length bearing of trend of drill bit Footpath is gradually increased, and one end of drilling rod is provided with the anchor ring being connected with equipment.

Also there is following technical characteristic in this utility model:

The outer wall of described drilling rod offers the plane that two plate faces are parallel to each other, and described two planes are along the length direction of drilling rod Insertion is arranged, and passes through two cambered surface transition and connect between two planes.

The shaft of described drilling rod is coordinated with action bars, and the rod end of action bars is provided with two planes of bayonet socket and the shaft of drilling rod Constitute and be engaged by clamping.

The end face side that described flight is located at the spiral extension initial segment of drill bit is provided with the first cutting edge, described flight End face both sides positioned at the spiral extension latter end of drill bit are respectively arranged with the second cutting edge.

Compared with the prior art, the beneficial effects of the utility model are embodied in: the drill bit one end boring stake is arranged to taper, And the conehead end outer wall in drill bit is extended flight, flight is gradually increased along bearing of trend, thus easily will bore Head screws in below ground, and the external diameter of flight is gradually increased setting, thus increasing the contact area with soil, and then can will bore Head is firmly fixed on underground, the steel wire rope that the setting of one end that drilling rod elevates above the soil is connected with external device, can avoid drill bit by In the situation bearing pulling force deficiency and leading to not fixed world equipment.

Specific embodiment

Referring to figs. 1 to Fig. 5, length adjustable is bored with the feature of stake, and details are as follows:

With boring stake, including drill bit 10, postpone in one end of drill bit 10 has drilling rod 30 to power equipment, and one end of described drill bit 10 sets It is set to taper, being extended positioned at the conehead end outer wall of drill bit 10 has flight 20, and described flight 20 is along the length of drill bit 10 The diameter of degree bearing of trend is gradually increased, and one end of drilling rod 30 is provided with the anchor ring 33 being connected with equipment.

Drill bit 10 one end boring stake is arranged to taper, and the conehead end outer wall in drill bit 10 is extended flight 20, Flight 20 is gradually increased along bearing of trend, thus easily drill bit 10 is screwed in below ground, and the external diameter of flight 20 Being gradually increased setting, thus increasing the contact area with soil, and then drill bit 10 firmly can be fixed on underground, drilling rod 30 is stretched The anchor ring 33 setting steel wire rope going out the one end on ground is connected with external device, and drill bit can be avoided to lead to no due to bearing pulling force deficiency The situation of method fixed world equipment.

For convenience of driving drilling rod 30 to rotate, in conjunction with shown in Fig. 2, the outer wall of described drilling rod 30 offers two plate faces and is parallel to each other Plane 31, described two planes 31 along drilling rod 30 length direction insertion setting, between two planes 31 pass through two cambered surface 32 mistake Cross connection；

The shaft of described drilling rod 30 and action bars 40 coordinate, and the rod end of action bars 40 is provided with the bar of bayonet socket 41 and drilling rod 30 Two plane 31 of body constitutes clamping engagement.In actual construction, block two on drilling rod 30 using the bayonet socket 41 of action bars 40 Plane 31, rotates drilling rod 30, thus drill bit 10 is screwed in below ground, two plane 31 alongst insertions of drilling rod 30, No matter operator all can block drilling rod 30 using the bayonet socket 41 of action bars 40 in which position, and then drilling rod 30 is screwed in ground Under, simple to operate, reliable.

In conjunction with Fig. 4 and Fig. 5, for convenience of drill bit 10 is threaded in or out ground, described flight 20 is located at the spiral shell of drill bit 10 The end face side that rotation extends initial segment is provided with the first cutting edge 21, and described flight 20 is located at the spiral extension latter end of drill bit 10 End face both sides are respectively arranged with the second cutting edge 22.It is located at the end face side of the spiral extension initial segment of drill bit 10 positioned at flight 20 Being provided with the first cutting edge 21, quickly can cut ground, thus conveniently piercing below ground, drill bit 10 being screwed out ground When, the end face both sides that described flight 20 is located at the spiral extension latter end of drill bit 10 are respectively arranged with the second cutting edge 22, are screwing out When, the first cutting edge 21 and the second cutting edge 22 will not cut soil further, and then during avoiding drill bit 10 to get out, new Advance on track it is ensured that drill bit 10 gets out along the hole back-out piercing, get out operation from facilitating drill bit 10.

It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and And in the case of without departing substantially from spirit or essential attributes of the present utility model, this practicality can be realized in other specific forms new Type.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, this practicality is new The scope of type is limited by claims rather than described above, it is intended that the containing of equivalency that will fall in claim All changes in justice and scope are included in this utility model.Any reference in claim should not be considered as limiting Involved claim.
