Abstract

The utility model relates to a fixing clamp for a pre-twisting wire, which comprises an upper clamping block, a lower clamping block and a plurality of bolts, wherein the upper clamping block and the lower clamping block are respectively provided with one or more than one through hole and screw hole which are correspondingly matched on both sides, and opposite inner surfaces of the upper clamping block and the lower clamping block are respectively provided with a center concave slot and two edge slots. When the upper clamping block and the lower clamping block are correspondingly overlapped and arranged on a combining body of conducting wires and the pre-twisting wire, the center concave slot can contain the conducting wires. The two edge slots are respectively used for two edge pins of the pulling ring end of the pre-twisting wire to pass through and be locked into the through hole and the screw hole by bolts, which enables the fixing clamp to be stably locked on the pre-twisting wire wound with the conducting wires. The pulling ring end of the pre-twisting wire is guaranteed not to reversely rotate to cause disconnection when the pulling ring end is pulled.

Description

The stationary fixture of preformed armor rods

Technical field

The utility model relates to a kind of stationary fixture of preformed armor rods, refers to a kind of fixing jig structure of specializing in the combination draw ring end that is locked in lead and preformed armor rods especially, by comprising that fixture block, following fixture block and most bolts are formed.

Background technology

As shown in Figure 5, known height hang on the overhead transmission line between iron tower, mainly be plurality of wires 10 (outer tool insulating barrier 101) to be wrapped up in be located at one and protect in the lines 20, again in protecting the lines 20 outside preformed armor rodses 30 that twine, promptly constitute the combination of a lead 10 (comprise and protect lines 20) and preformed armor rods 30, the end of preformed armor rods 30 then forms a draw ring end 301, the application of preformed armor rods 30, it mainly is the construction that continues of wire line being built for simplifying, and guardwire avoids impaired, and prolongs service life, reduce maintenance frequency, promote lead useful life, and make things convenient for the maintenance of circuit, rush to repair, still can keep the pulling force and the electric conduction quantity of former lead; The combination of right known lead 10 (comprise and protect lines 20) and preformed armor rods 30, because of preformed armor rods 3 be interleaved be wrapped in parcel lead 10 continuously protect lines 20 outsides, so the draw ring end 301 of preformed armor rods 30 is during by powerful dragline, tend to because of the reverse rotation stretcher strain of stranded position, so cause preformed armor rods 30 phenomenon that gets loose, the stability after being unfavorable for constructing.

Summary of the invention

Main purpose of the present utility model is to provide a kind of stationary fixture of preformed armor rods, it comprises fixture block on, once fixture block and most bolts, on, following fixture block is offered one or more respectively at both sides and is coupling corresponding perforation and screw, and last, the relative inner face of following fixture block is equipped with a drop-center and two limit grooves, to go up during use, following fixture block bridges relatively at the combination of lead and preformed armor rods, drop-center holds the lines that protect that wrap up lead, two limit grooves can pass through for two limit pin of preformed armor rods draw ring end respectively, lock perforation and screw with bolt again, stationary fixture firmly is locked on the combination of lead and preformed armor rods, so the draw ring end of preformed armor rods is during by powerful dragline, its stranded position can't reverse rotation and cause stretcher strain, therefore can guarantee effectively that preformed armor rods will not get loose.

Embodiment

As shown in Figures 1 and 2, the stationary fixture of preformed armor rods of the present utility model, its formation comprises: fixture block 1 on, once fixture block 2 and most bolts 3, wherein:

Last fixture block 1 is one slightly to be camber arch shape and to have the plate body of suitable thickness, and one or more perforation 11 is respectively offered in its both sides, and is provided with a drop-center 12 and two limit grooves 13 at inner face;

Following fixture block 2, be that coupling is corresponding to last fixture block 1, also be one slightly to be camber arch shape and to have the plate body of suitable thickness, one or more screw 21 is respectively offered in its both sides, and inner face and be provided with a drop-center 22 and two limit grooves 23, perforation 11, drop-center 2, the limit groove 13 relative couplings of this screw 21, drop-center 22, limit groove 23 and last fixture block 1;

A most bolt 3 are the perforation 11 and screw 21 (as Fig. 2) of locking aforementioned upper and

lower fixture block

1,2 for running through;

As shown in Figures 3 and 4, stationary fixture as above-mentioned composition, when using, it will go up, following

fixture block

1,2 bridge is relatively comprising on the combination that protects lines 20 and preformed armor rods 30 of lead 10, make drop-

center

12,22 can hold and protect lines 20 (having included lead 10), and two

limit grooves

13,23 supply two limit pin of preformed armor rods 30 draw ring ends 301 to pass through respectively, and then utilize bolt 3 to lock perforation 11 and screw 21, make stationary fixture can firmly be locked in (as shown in Figures 3 and 4) on the above-mentioned combination, with the draw ring end 301 of guaranteeing preformed armor rods 30 during by powerful dragline, its stranded position can reverse rotation and cause stretcher strain, is therefore guaranteed that preformed armor rods 30 can not get loose.

According to the foregoing description, it only is the explanation that exemplifies of the utility model major technique, it is not in order to limiting the utility model technical scope, relates to equivalent application such as or based on preceding paragraph technological means do simple and easy change or displacement, all should be considered as belonging to the utility model technical scope; For example at the alteration of form of upper and

lower fixture block

1,2, if the upper and

lower fixture block

1,2 of the circle of employing, ellipse, cerioid or other face shaping, all its has the utility model primary structure feature, all still do not take off the utility model technical scope, for example increase again, also belong to simple and easy equivalence techniques at the number of described perforation 11 with screw 21 and bolt 3.
