Description

From drawing self-locking burst Combined anchor ear

Technical field

The utility model relate to concrete bar in the line sending road that prevents from transmitting electricity topple over and rupture certainly draw self-locking burst Combined anchor ear.

Background technology

Steel concrete concrete bar is the most frequently used electric pole during electric power is carried, particularly in the high pressure transmission line of electricity, not only transmission line of electricity is long for it, and usually to cross over the mountain ridge, river and field, because impact and the restriction of construction and geology, cause some concrete bar embedded depth of foundation inadequate, root basis and backguy are insecure, the concrete bar is subjected to pulling force and external environment condition function influence, easily produce vertical or horizontal crackle, cause the coarse stone bar that bar occurs, the situation of disconnected bar etc., not only can cause electric power to carry interrupts, the conveying cost that increases electric power, impact are produced and life, and can produce the electric power safety accident.

The utility model content

For the problem that concrete bar in the above-mentioned prior art easily produces bar, the bar that breaks brings, the utility model provides a kind of concrete bar that can not make to produce vertical or horizontal crackle, can prevent effectively that the concrete bar from falling bar and disconnected bar, guarantee that electric power carries normal from drawing self-locking burst Combined anchor ear.

The technical scheme that the technical problems to be solved in the utility model is taked is: described from drawing self-locking burst Combined anchor ear to comprise gripper shoe, strain plate, U-loop and hoop plate, described gripper shoe interval arranges, described gripper shoe two ends are mutually vertical, between the adjacent end of two gripper shoes, be movably set with strain plate with screw shaft, described strain plate movable upper end is connected with U-loop, the strain plate lower end is provided with anchor ear, and U-loop links to each other with backguy one end.

When simultaneously downward fastening backguy, the strain plate rotation moves inward anchor ear to hold tightly the concrete bar fixing simultaneously.

The utility model is applicable to 10KV-220KV and does not use with the steel concrete concrete bar of climbing nail, and its installation instructions using method is:

1) device checks: need check the anchor ear device outward appearance using, confirm each position especially connecting portion without damaged, without heavy wear and corrosion situation,

2) check before the bar: step on the bar operating personnel and must determine before operation whether concrete pole-footing section and backguy be firm, stringing band stressing conditions and abrasion condition etc. are determined the easy breakpoint of concrete bar,

3) two staff are enclosed within concrete pole-footing section with U-shaped ring, strain plate, gripper shoe with bolton together, and U-shaped ring is passed in 4 backguys,

4) other 4 staff are mutually 90 degree angle directions according to four of topography and geomorphology selections and lay anchoring pile.Solid soil is selected in the anchoring pile place as far as possible, and anchoring pile should become with ground 45 degree to squeeze in the soil, and the degree of depth is not less than 1 meter, in case of necessity can the stake of the company of employing etc. mode increase anchoring pile,

5) with four backguy one ends fixedly on the anchoring pile, two staff stand in the places of symmetry direction beyond 50 centimeters of the electric poles, with the strut jack-up anchor ear device that is equipped with,

6) whether four of the anchoring pile place staff's finder lifting heights put in place, slowly discharge wire rope along with anchor ear device rises, and guarantee that anchor ear steadily rises to the target location,

7) in the reason hoop device uphill process, the operating personnel forbids standing in might the break direction of bar of concrete bar,

8) so anchor ear device must rise to more than the easily broken knick point of concrete bar, generally highly be advisable more than 2/3 with the concrete bar, otherwise can't play protective action,

9) reach behind the target location should the maintenance level for device, cubic backguy should be simultaneously even slow stringing, guarantee hoop bar force balance,

10) when cubic backguy begin stressed after, two personnel unclamp strut under the bar, leave concrete pole-footing section, cubic backguy continues evenly slowly stringing, after obvious tension force is born in backguy, and device is fixing, namely stops; Such as device loosening phenomenon is arranged, should re-start adjustment,

11) in the cubic backguy stringing process, prevent concrete bar discontinuity, disconnected bar phenomenon occurs,

10) step in the bar operation process four necessary rear personnels in anchoring pile place, the fixing situation of supervision anchoring pile the maintainer.As it is stressed excessive and cause mobile situation to find that anchoring pile has, and should stop immediately working on the bar, and the operating personnel is lower beam immediately, again reinforces rear upper boom until anchoring pile,

11) work is complete, on the bar behind the whole lower beams of operating personnel, and can detaching device.Unloading process is opposite with installation process, and two staff are on symmetry direction, and device is withstood with strut in the place that stands in outside 50 centimeters of electric poles, and cubic backguy is evenly slowly loosened simultaneously.Device slow decreasing under the effect of strut arrives ground,

12) in complete, the unloading process of device dismounting, cubic backguy is forbidden to unclamp suddenly,

13) stripping device checks whether component are excellent, and if any breakage, timely and manufacturer contacts replacing, can not arbitrarily change voluntarily.

The utility model can prevent that the concrete bar from producing vertical or horizontal crackle, makes in the transmission line of electricity concrete bar not fall bar, disconnected bar, can not only guarantee that electric power carries normally, reduces electric power and carries cost, and can prevent that the electric power safety accident from occuring.The utility model compact conformation, dismounting, carry, operation and maintenance is convenient, durable reliability is strong.
