In some embodiments, the clip is lined with a rubber pad.

In some embodiments, the push plate and the side push plate are provided with cambered surfaces.

In some embodiments, the side push plate cambered surface edges are frosted.

In some embodiments, the hydraulic jack is 2t gauge.

In some embodiments, a hook is arranged on each side of the middle of the hydraulic jack.

To sum up, the utility model discloses following beneficial effect has:

this kind of correction instrument, during the correction, bulldoze the subassembly and not only played the corrective action to the wire splicing sleeve, two side push pedals have still increased the point of bulldozing to the wire splicing sleeve simultaneously for the stress site of wire splicing sleeve becomes many, and the atress is more even, and the surface of wire splicing sleeve is more level and smooth after rectifying, improves the life of wire splicing sleeve.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, a simple and easy overhead transmission line wire splicing sleeve correction tool, including hydraulic jack 5, hydraulic jack 5's base both sides respectively are provided with a fixed establishment 3, respectively are connected with a fag end 2 on two fixed establishment 3, and the one end that fixed establishment 3 was kept away from to two fag ends 2 respectively is connected with a clamp 1, and hydraulic jack 5's pars contractilis are provided with one and bulldoze subassembly 4, and bulldoze subassembly 4 including bulldozing board 41, bulldoze board 41 both sides and respectively rotate through the torsional spring and be connected with a side push pedal 42. When the device is used, an operator clamps the two clamps 1 at two ends of a bent part of a wire splicing sleeve respectively, then the two rope sleeves 2 and the fixing mechanism 3 are adjusted to keep the same vertical axis of the rope sleeves 2, the rope sleeves 2 are preferably steel rope sleeves to avoid the phenomenon that the coaxial lines cannot be kept due to wind blowing, the fixing mechanism 3 is preferably a double-cap bolt to meet the fixing requirement and low in cost, then a nut of the fixing mechanism 3 is screwed for fixing, then the pushing and pressing component 4 is aligned to the bent part of the wire splicing sleeve, the operator supports a base of the hydraulic jack 5 with one hand and controls a handle with the other hand to enable the telescopic part of the hydraulic jack 5 to extend and push the pushing and pressing component 4 to slowly move towards the bent part of the wire splicing sleeve, and the pushing and pressing component 4 pushes the bent part of the wire splicing sleeve to slowly move along the extending direction of the telescopic part of the hydraulic jack 5 at a constant speed, in the pushing process, the side push plate 42 contacts with the wire splicing sleeve before the push plate 41 contacts with the wire splicing sleeve, and then is blocked by the wire splicing sleeve, so that the two side push plates 42 are opened, when the push plate 41 also contacts with the wire splicing sleeve, the two side push plates 42 are not opened any more, then the push plate 41 and the side push plate 42 simultaneously contact and push the wire splicing sleeve, a point for applying thrust to the wire splicing sleeve is increased, the surface covered by the push plate 41 after correction and the surrounding crease are avoided, then the hydraulic jack 5 is controlled to reset, the push component 4 is also kept away from the wire splicing sleeve, the two side push plates 42 reset under the action of the torsion spring, and finally the steps are repeated for a plurality of times until the bending part of the wire splicing sleeve is completely corrected, the correcting tool is simple in operation and convenient for flexible operation in high altitude, and increases the thrust point to the wire splicing sleeve, avoiding crease after correction and improving the correction quality of the wire splicing sleeve.

In some embodiments, the band 1 is lined with a rubber pad to protect the wire splicing sleeve from damage when the band 1 is used to clamp the wire splicing sleeve.

In some embodiments, the pushing plate 41 and the side pushing plate 42 are both provided with an arc surface, and the design of the arc surfaces can make the pushing plate 41 and the side pushing plate 42 be attached to the bending part of the wire splicing sleeve more tightly, so as to further increase the stressed area and prevent the pushing force from being concentrated at one position.

In some embodiments, the edges of the cambered surfaces of the side push plates 42 are both frosted, and the frosted surfaces of the two side push plates 42 repeatedly polish and remove burrs on the surface of the wire splicing sleeve along with the reciprocating motion of the two side push plates 42 on the wire splicing sleeve in the process of repeatedly pushing and pressing the wire splicing sleeve, so that the correction quality of the wire splicing sleeve is further improved.

In some embodiments, the hydraulic jack 5 adopts 2t specification, so that the operator can conveniently carry to high altitude to carry out operation, the weight of the tool is reduced under the condition of meeting the thrust, the cost is saved, and even a single person can use the correction tool.

In some embodiments, the two sides of the middle of the hydraulic jack 5 are respectively provided with the hook 6, so that the rope sling 2 and the hoop 1 can be hung during high-altitude operation, and an operator can take and store the hoop 1 conveniently.

The specific embodiments are only for explaining the present invention, and it is not a limitation to the present invention, and those skilled in the art can make modifications to the embodiments without inventive contribution as required after reading the present specification, but all the embodiments are protected by patent law within the scope of the claims of the present invention.
