Abstract

The invention discloses a ground anchor, which comprises an inhaul cable connecting piece and a tensile assembly connected with the inhaul cable connecting piece, wherein the tensile assembly comprises a plurality of tensile units and a connecting piece for detachably connecting the tensile units. The ground anchor can be detached for transportation and assembled for use, is flexible and convenient in structural alteration, and is suitable to be taken as a temporary inhaul cable disk; each part has a steel frame structure, so that high bearing capacity is achieved, convenience is brought to recycling, the cost is reduced, and a good economic benefit is achieved.

Description

Earth anchor

Technical field

The invention belongs to earth anchor field, relate to a kind of combined type earth anchor that can reuse, detachably transport.

Background technology

During the construction of power circuit tower bar, to use anchor instrument, but the earth anchor using mostly at present is the cement cable quadrant of concreting, this cement cable quadrant weight is larger, be suitable for using as permanent cable quadrant, if use as temporary guy dish, carry transportation inconvenience, be unfavorable for that the problems such as recycling exist, although the temporary guy dish while also having at present other forms of earth anchor (as ship sections earth anchor) to can be used as the construction of tower bar is used, but these earth anchors have again a common problem: be only applicable in power circuit tower bar that trnamission capacity is less, for those trnamission capacities compared with large tower bar because its load that can bear is compared with little and can not be suitable for, cannot meet construction requirement.

Summary of the invention

In view of this, the object of the present invention is to provide a kind of alternative cement cable quadrant, be convenient to transportation, can recycling, be suitable for the combined type earth anchor as temporary guy dish.

For achieving the above object, the invention provides following technical scheme: a kind of earth anchor, comprise drag-line connector and the tension assembly being connected with drag-line connector, described tension assembly comprises several tension unit and by the connector of the detachable connection in tension unit.

Further, described tension unit and tensile members are steel pipe or steel bar, and described connector comprises and be arranged on the junction plate at tension unit middle part and be arranged on the bolt on junction plate, and described tension unit connects into bamboo raft type structure by junction plate and bolt.

Further, described drag-line connector is the boatswain chair being connected with tension unit, is provided with drag-line connecting hole on described boatswain chair.

Further, also comprise the covering covering on tension unit, described covering is provided with for covering being fixed on to the covering frame on tension unit.

Beneficial effect of the present invention is:

(1) by a plurality of parts, be assembled, when travelling bogie cannot transport, can be disassembled into several parts is carried respectively by several workmans, be convenient to transportation, be particularly suitable for the ungetable areas such as mountain area, during use, be assembled into one, convenient, flexible, after finishing using, dig out and take away, be suitable for using as temporary guy dish;

(2) several tensions unit is connected to form bamboo raft type structure by connector, and its overall structure specification, supporting capacity are equivalent to cement cable quadrant, completely place of cement cable quadrant, each several part adopts steel frame construction, recycling completely, has reduced cost, good in economic efficiency.

Accompanying drawing explanation

In order to make object of the present invention, technical scheme and beneficial effect clearer, the invention provides following accompanying drawing and describe:

Fig. 1 is structural representation of the present invention;

Fig. 2 is the explosive view of Fig. 1;

Fig. 3 is forward view of the present invention after removal covering;

Figure 4 Wei 〦 type structural representations;

Fig. 5 is+type structural representation;

Fig. 6 is contiguous block type structural representation.

The specific embodiment

Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.

As shown in Figure 1, Figure 2, Figure 3 shows, the earth anchor of the present embodiment, comprise drag-line connector 1 and the tension assembly 2 being connected with drag-line connector 1,2 of described tension groups comprise three tension unit 21 and are arranged on the connector 22 at 21 middle parts, tension unit, tension unit 21 is herein seamless steel pipe, the bolt 222 of connector 22 for being fixed on the junction plate 221 on seamless steel pipe and adjacent junction plate 221 being fixed together; During use, seamless steel pipe connects into bamboo raft type structure by junction plate 221 and the bolt 222 at middle part.

The seamless steel pipe of the present embodiment can be at φ 102mm, φ 121mm, φ 140mm, wall thickness is to select in several specifications of 5～6mm, steel pipe earth anchor specification after composition is consistent with existing cement cable quadrant specification, certainly, tension unit 21 herein also can select the steel bar of other types can achieve the goal equally.

The drag-line connector 1 of the present embodiment is the boatswain chair that a structure is similar to junction plate 221, and boatswain chair is provided with drag-line connecting hole 11; This boatswain chair replaces the middle part that junction plate 221 is arranged on a seamless steel pipe, and the junction plate 221 remaining on two seamless steel pipes all fixes with boatswain chair.

In the present embodiment, also comprise the covering 3 covering on tension unit 21, on covering 3, be welded with and can block the covering frame 4 of embracing seamless steel pipe, by covering frame 4 is fixed on covering 3 on seamless steel pipe, cover reliably difficult drop-off; Covering 3 has sheltered from the gap between adjacent seamless steel pipe, has increased the uplift resistance of earth anchor.

This programme also has other several variant, as the girder structure of drag-line connector 1 Wei 〦 type or+type structure, each tension unit 21 is all fixed on (as Fig. 4,5) on drag-line connector 1 by junction plate 221, or what each 21 middle parts, tension unit were fixing is square contiguous block 223, drag-line connector 1 is hinged on a middle contiguous block 223 (as Fig. 6).

Finally explanation is, above preferred embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is described in detail by above preferred embodiment, but those skilled in the art are to be understood that, can to it, make various changes in the form and details, and not depart from the claims in the present invention book limited range.
