Abstract
The utility model discloses a ground anchor comprising an anchor rod sleeve, an anchor rod and helical blades. The upper end of the anchor rod is connected with the anchor rod sleeve; the anchor rod sleeve is provided with through holes; the lower end of the anchor rod is connected with a drilling tool with an inner knife edge; the helical blades are arranged at the lower end of the anchor rod and fixedly connected with the anchor rod into a whole; and the helical blades are arranged in an evolvent form from bottom to top. The ground anchor can be conveniently knocked into ground in areas with hard geology or high-cold frozen earth and can bear large anchor rope tension; and the ground anchor is simple in structure and convenient and fast in installation.
Description
Technical field
The utility model relates to a kind of earth anchor, especially relates to the earth anchor of a kind of fixedly rig, workover rig derrick and high tower guy wire.
Background technology
Relate in the construction operations such as erectting derrick, high tower in underground work, geological prospecting and other, need with earth anchorage rig, workover rig derrick and high tower guy wire etc.At present, earth anchor commonly used adopts the oil pipe transformation of the way to form, and a taper tip is changed a social system in the anchor pole lower end, along taper tip welding helical form steel plate, anchor pole upper end welding oil pipe, and perforate on oil pipe.Press down by rotation, earth anchor is driven underground.In the earth anchor installation process, always the earth anchor tip to be compressed into the bottom surface earlier, again earth anchor is screwed in.Before the earth anchor effective blade screws in ground, need provide enough downforce,, then need to adopt earlier the boring of import drilling tool can make earth anchor again if in the harder or high alpine frost soil of geology area.Increase workman's fatigue strength with this earth anchor, greatly reduced operating efficiency.
Summary of the invention
The purpose of this utility model is exactly in order to overcome the shortcoming of prior art, a kind of earth anchor to be provided.It can squeeze into the stratum easily in the harder or high alpine frost soil of geology area, because helical blade adopts the involute form to arrange, can bear bigger guy wire pulling force.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of earth anchor, form by anchor pole sleeve pipe, anchor pole and helical blade.The anchor pole upper end is connected with the anchor pole sleeve pipe, wherein has through hole on the anchor pole sleeve pipe; The anchor pole lower end is connected with interior edge of a knife drilling tool, and helical blade is connected to one in the anchor pole lower end and with anchor pole, and helical blade is served as reasons down and up arranged with the involute form.
The beneficial effects of the utility model are: this earth anchor can be squeezed into the stratum easily in the harder or high alpine frost soil of geology area, can bear bigger guy wire pulling force, and is simple in structure, quick and easy for installation.

Among the figure: 1. edge of a knife drilling tool 2. helical blades 3. anchor poles 4. anchor pole sleeve pipes in.
The specific embodiment
As shown in Figure 1, 2, a kind of earth anchor, it is made up of anchor pole sleeve pipe (4), anchor pole (3) and helical blade (2).Anchor pole (3) upper end is welded to connect with anchor pole sleeve pipe (4), the anchor pole sleeve pipe is opened the hole on (4), anchor pole (3) lower end and interior edge of a knife drilling tool (1) are welded to connect, helical blade (2) is connected to one in anchor pole (3) lower end and with anchor pole (3), and helical blade (2) is served as reasons down and up arranged with the involute form.
Claims (3)
1. earth anchor, it is made up of anchor pole sleeve pipe (4), anchor pole (3) and helical blade (2), it is characterized in that: anchor pole (3) upper end is connected with anchor pole sleeve pipe (4), anchor pole (3) lower end is connected with interior edge of a knife drilling tool (1), and helical blade (2) is connected to one in anchor pole (3) lower end and with anchor pole (3).
2. a kind of earth anchor according to claim 1 is characterized in that: described helical blade (2) is served as reasons down and is up arranged with the involute form.
