Abstract
The utility model discloses a kind of screw pull rod, comprise that the body of rod that lower end is slightly sharp and winding are at the helical blade of body of rod outer wall; The arranging of the utility model center platen and helical blade can increase the whole area of contact with underground earth of pull bar, increase frictional force, avoid because wind-force is excessive or earth is soft, the moist pull bar causing gets loose, be applicable to the environment such as wetland, quagmire, paddy field, can be used as pull bar and the revetment pull bar of utility pole.
Description
Technical field
the utility model relates to a kind of screw pull rod.
Background technique
utility pole is for cable being erected facilitate the structure of electric power or telecommunications remote transmission.Conventionally cable can be by highland frame on utility pole, and this can or stride across streets and buildings away from pedestrian.This with electric wire bridge, to play the method cost of cable transmission electricity lower, so application scale is very large, almost has the place of power supply just to there will be utility pole.In general settlement, utility pole can stand in roadside by cement production systD column, and early stage or provisional setting can be used wood to replace, and pulls and assists a ruler in governing a country in case utility pole falls down sometimes with steel wire.
existing steel wire one end for the utility pole of assisting a ruler in governing a country is fixed on utility pole, the other end generally penetrates earth by fixed blocks such as steel nail, steel prickers and realizes tension utility pole, existing anchor structure is comparatively single, and comparatively few with earth area of contact, in using process, be easy to the earth that gets loose out, and lose the original auxiliary effect of pullling of steel wire.Existing fixed block only can be pricked and be located in the harder earth of soil property in addition, and in the environment such as cannot be applicable to wetland, quagmire, paddy rice, so Applicable scope is less.
Summary of the invention
the utility model object is: a kind of simple in structure, screw pull rod of being applicable to various soil property environment is provided.
the technical solution of the utility model is: a kind of screw pull rod, comprises that the body of rod that lower end is slightly sharp and winding are at the helical blade of body of rod outer wall.
one side of the described body of rod is connected with pressing plate by link, and the lower end of described pressing plate has the insertion angle being obliquely installed, and described link is connected with the body of rod to hold and is provided with rotary bearing, and described rotary bearing is set on the body of rod and can rotates relative to the body of rod.The arranging of pressing plate can increase the whole area of contact with underground earth of pull bar, coordinates helical blade simultaneously, increases frictional force, avoids because wind-force is excessive or earth is soft, the moist pull bar causing gets loose.
underground in order to be connected steel wire and to facilitate the body of rod to penetrate between convenient and the rod member needing reinforcement, the upper end portion of the described body of rod has the vertical draw ring of indulging.
the utility model has the advantages that:
1, arranging of the utility model center platen and helical blade can increase the whole area of contact with underground earth of pull bar, increase frictional force, avoid because wind-force is excessive or earth is soft, the moist pull bar causing gets loose, be applicable to the environment such as wetland, quagmire, paddy field, can be used as pull bar and the revetment pull bar of utility pole.
, the design of body of rod top draw ring in the utility model, not only facilitated with the rod member needing reinforcement between be connected steel wire, facilitated installation simultaneously, during installation, can in the draw ring at body of rod top, wear steel pipe, then by two people while press down turn-take just the body of rod with helical blade can be penetrated underground, easy to operate, quick.
Accompanying drawing explanation
below in conjunction with drawings and Examples, the utility model is further described:
fig. 1 is the structural representation of pull bar in the utility model;
fig. 2 is that the utility model is used view.
wherein: 1 body of rod; 2 helical blades; 3 links; 4 pressing plates; 5 insert angle; 6 draw rings; 7 rotary bearings.
Embodiment
embodiment: as depicted in figs. 1 and 2, a kind of screw pull rod, comprises that the lower end slightly sharp body of rod 1 and winding are at the helical blade 2 of the body of rod 1 outer wall.
one side of the described body of rod 1 is connected with pressing plate 4 by link 3, and the lower end of described pressing plate 4 has the insertion angle 5 being obliquely installed, and described link 3 is connected with the body of rod 1 to hold and is provided with rotary bearing 7, and described rotary bearing 7 is set on the body of rod 1 and can rotates relative to the body of rod 1.In the present embodiment, preferred described pressing plate 4 is arc plate.
underground in order to be connected steel wire and to facilitate the body of rod to penetrate between convenient and the rod member needing reinforcement, the upper end portion of the described body of rod 1 has the vertical draw ring 6 of indulging, as shown in Figure 2.
during use, can in the draw ring 6 at the body of rod 1 top, wear steel pipe, then by two people, while pressing down to turn-take, just can the body of rod with helical blade 21 be penetrated underground, in rotary course, when pressing plate 4 is conflicted ground, press down pressing plate 4 simultaneously, make its insertion depth of also following the body of rod progressively insert underground, when the body of rod and pressing plate penetrate underground and draw ring substantially completely and are exposed to ground, complete installation, next as long as tie up and establish steel wire or other reinforcing cords between utility pole or other rod members needing reinforcement and draw ring.
2 of the utility model center platen 4 and helical blade arranges the area of contact that can increase pull bar integral body and underground earth, increase frictional force, avoid because wind-force is excessive or earth is soft, the moist pull bar causing gets loose, be applicable to the environment such as wetland, quagmire, paddy field, can be used as pull bar and the revetment pull bar of utility pole.
below be only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.In addition to the implementation, the utility model can also have other mode of execution.All employings are equal to the technological scheme of replacement or equivalent transformation formation, within all dropping on the utility model scope required for protection.
