Abstract
The utility model relates to a ground anchor which can be used for fixing large-sized movable type tower and frame guy ropes. The utility model is composed of a cone, a first stage taper sleeve, a second stage taper sleeve, a screw rod, an anchor body, a supporting tube and a side hole nut, wherein the side hole nut and the cone form screw connection with both ends of the screw rod, and the first stage taper sleeve, the second stage taper sleeve, the anchor body and the supporting tube are sheathed at the center section of the screw rod. A drill head of the ground anchor is driven by a hand electric drill with a large horsepower or an electric hammer, a ground anchor hole is drilled and the diameter of the drill head is equal to that of an anchor body. The utility model which is assembled is arranged in the drilled ground anchor hole, the side hole nut arranged at an upper part is rotated, and the first stage taper sleeve, the second stage taper sleeve and an anchor fluke are opened to an umbrella shape through the screw rod, the supporting tube and the cone. When the opening angle of the anchor fluke reaches the design requirement, the side hole nut can be disassembled, the supporting tube is taken out and the side hole nut is installed for fixing the guy rope. The supporting tube can be repeatedly used.
Description
One, art field
The utility model belongs to the instrument of a kind of fixing large-scale mobile type tower, frame guy wire.
Two, background technology
General fixedly Large Towers, frame need four guy wires at least.Guy wire one end is fixed on the top of tower, frame, and the other end by earth anchorage on the ground.Common earth anchor is manually to dig one long 2 meters, wide 0.8 meter, dark about 2 meters heatable adobe sleeping platform on the ground, imbeds a steel pipe that is about 2 meters, steel wire loop of steel pipe intermediate sleeve fixedly guy wire that bassets.This flush type earth anchor, construction is wasted time and energy, and dig pit northerly especially winter, very difficulty.In recent years, a kind of mobile ground anchor vehicle is arranged, utilize the power of automobile that the screw anchor of the similar tapping screw of shape is screwed in underground fixedly guy wire.When mobile tower, frame, by mobile ground anchor vehicle screw anchor is screwed out ground again and reuse.The operating expenses of this earth anchor is very high, and in northerly winter, it is underground quite difficult that mobile ground anchor vehicle screws in screw anchor, just can't construct at extremely frigid zones.
Three, summary of the invention
Waste time and energy and the high problem of screw anchor mounting cost in order to solve existing flush type earth anchor installation, the utility model provides a kind of earth anchor, and heavy manual labor has not only been removed in the installation of this earth anchor, and expense is low.
The technical scheme that its technical problem that solves the utility model adopts is: cone and side opening nut are by being threaded in the two ends of screw rod, and one-level tapered sleeve, secondary tapered sleeve, anchor body and stay pipe are sleeved on the stage casing of screw rod.Drive the earth anchor drill bit with a bigger hand electric drill or an electric hammer of power, bore an anchor hole, bit diameter is identical with anchor body diameter.The earth anchor that assembles put into bore good anchor hole, rotation top side opening nut, the one-level tapered sleeve, secondary tapered sleeve and the anchor fluke that make the bottom by the effect of screw rod, stay pipe and cone be in underground flare up umbrella, thereby reached the purpose at underground fixedly earth anchor.
The beneficial effects of the utility model are: the guy wire that can firmly fix tower, frame.Experiment showed, that at loess formation 1.8 meters of earth anchor depth of settings can bear the pulling force more than 5 tons on the direction that becomes 45 degree with ground.

Accompanying drawing 4 is the diagrammatic sketch of analysing and observe of the utility model anchor body structure
Among the figure: 1 cone, 2 one-level tapered sleeves, 3 secondary tapered sleeves, 4 screw rods, 5 anchor bodies, 6 stay pipes
7 side opening nuts, 8 anchor flukes, 9 guide strips
Five, the specific embodiment
In conjunction with the accompanying drawings, the specific embodiment of the present utility model is described.As shown in Figure 1, cone (1), one-level tapered sleeve (2), secondary tapered sleeve (3), screw rod (4), anchor body (5), stay pipe (6), side opening nut (7) are assembled by order illustrated.The big end of one-level tapered sleeve (2) and secondary tapered sleeve (3) is cut into many lobes uniformly, the lobe number is identical and be connected at the less end of diameter and be integral, guide strip (9) is housed in the cutting groove of one-level tapered sleeve (2), secondary tapered sleeve (3), and an end of guide strip (9) is welded on the bigger end face of tapered sleeve diameter.Anchor body (5) is a cylindrical body, and an end is cut many lobes uniformly becomes anchor fluke (8), and its quantity is identical with tapered sleeve lobe number.During assembling, guide strip (9) (see figure 3) that is welded on one-level tapered sleeve (2) end face will be inserted in the side channel of secondary tapered sleeve (3), the guide strip of secondary tapered sleeve (9) will insert in the side channel between anchor fluke (8) (see figure 4) of anchor body (5), and anchor fluke (8) is opened.The utility model that assembles is put into the good anchor hole of brill, and rotation top side opening nut (7) makes one-level tapered sleeve (2), secondary tapered sleeve (3) and the anchor fluke (8) of bottom in underground flare up umbrella (see figure 2) by the effect of screw rod (4), stay pipe (6) and cone (1).The open angle of anchor fluke (8) reaches designing requirement can unload lower-side hole nut (7), takes out stay pipe (6) and refills fixedly guy wire of upper-side hole nut (7).Stay pipe (6) is reusable.
Claims (4)
1, a kind of earth anchor, it is made of cone, one-level tapered sleeve, secondary tapered sleeve, screw rod, anchor body, stay pipe and side opening nut, it is characterized in that: cone (1) and side opening nut (7) are by being threaded in the two ends of screw rod (4), and one-level tapered sleeve (2), secondary tapered sleeve (3), anchor body (5) and stay pipe (6) are sleeved on the stage casing of screw rod (4).
2, according to the described earth anchor of claim 1, it is characterized in that: the big end of one-level tapered sleeve (2) and secondary tapered sleeve (3) is cut into many lobes uniformly, the lobe number is identical and be connected at the less end of diameter and be integral, guide strip (9) is housed in the cutting groove of one-level tapered sleeve (2), secondary tapered sleeve (3), and an end of guide strip (9) is welded on the bigger end face of tapered sleeve diameter.
