Abstract

A clamping device for a live line insulator string replacement is mainly used to solve the problem that the conventional clamping device is not general, and is characterized in that a clamping frame (1) is inverted trough-shaped, the left and right sides of front and back vertical plates are equipped with longitudinal notches (2)respectively, and the left and right sides of a top plate are connected with telescopic screw sleeves (3) longitudinally; the telescopic screw sleeves (3) are connected with main telescopic screw rods (4) via screw threads, and ratchet wrenches are arranged on the outsides of the lower ends of the main telescopic screw rods (4); auxiliary telescopic screw rods (6) are connected in the lower ends of the main telescopic screw rods (4) via screw threads, and lifting hooks (7) are arranged below the auxiliary telescopic screw rods (6). The clamping device for the live line insulator string replacement has the characteristics of being strong in generality and being safe and reliable.

Description

Charged for replacement insulator string jig
Technical field
The utility model relates to the used instrument of a kind of electric power overhaul, especially charged for replacement insulator string jig.
Background technology
In the electric power overhaul field, the charged for replacement insulator is action main in the power transmission sequence live line working.Change the employed jig of straight line insulator string now; It is difference according to shaft tower cross-arm structural shape; Though the overhead line structures cross-arm that is same electric pressure all has than big-difference; Thereby will prepare out different cross-arm jigs for different cross-arm structural shapes and change the straight line insulator string. cause very big difficulty so just for the supporting of instrument, and be uneconomic.
Summary of the invention
In order to solve the existing uncurrent problem of jig.The utility model provides a kind of charged for replacement insulator string jig.This charged for replacement insulator string jig has highly versatile and safe and reliable characteristics.
The technical scheme of the utility model is: this charged for replacement insulator string jig comprises the card frame.The card frame is for falling flute profile; On the left and right sides of front and back riser gap is longitudinally arranged respectively; Vertically be connected with telescopic swivel nut on the top board of the left and right sides; Telescopic swivel nut is by the main flexible screw mandrel that has been threaded; Ratchet spanner outside the main flexible screw mandrel lower end; Main flexible screw mandrel is interior down by the secondary flexible screw mandrel that has been threaded, and under the secondary flexible screw mandrel suspension hook is arranged.
The utlity model has following beneficial effect: this charged for replacement insulator string jig has gap longitudinally respectively owing to adopt the card frame for falling flute profile on the left and right sides of front and back riser, vertically be connected with telescopic swivel nut on the top board of the left and right sides; Telescopic swivel nut is through the main flexible screw mandrel that has been threaded, the outer ratchet spanner in main flexible screw mandrel lower end, main flexible screw mandrel down in through the secondary screw mandrel that stretches that has been threaded; Under the secondary flexible screw mandrel suspension hook structure is arranged, utilize the cross-arm of the gap deck of card frame, rotate the main flexible screw mandrel of ratchet spanner drive again and rotate with the secondary screw mandrel that stretches at shaft tower; Promote or transfer the straight line insulator string through the suspension hook rope; Be implemented in that the charged for replacement insulator is the power transmission sequence live line working on the different structure shaft tower cross-arm, and then the expanding application scope, reduction work is dangerous; Strengthen fail safe, and structure and simple to operate.This charged for replacement insulator string jig has highly versatile and safe and reliable characteristics thus.
Description of drawings:
Accompanying drawing 1 is that the utility model is overlooked the sectional structure sketch map;
Accompanying drawing 2 is Fig. 1 upward views.
1-card frame among the figure, 2-gap, 3-telescopic swivel nut, 4-master's screw mandrel that stretches, 5-ratchet spanner, the secondary flexible screw mandrel of 6-, 7-suspension hook.
Embodiment:
Below in conjunction with accompanying drawing the utility model is described further:
Shown in accompanying drawing, this charged for replacement insulator string jig comprises card frame 1.Card frame 1 has gap 2 longitudinally respectively for falling flute profile on the left and right sides of front and back riser, by gap 2 this charged for replacement insulator string jig is fixed on the cross-arm on the tower; Vertically be connected with telescopic swivel nut 3 on the top board of the left and right sides; Telescopic swivel nut 3 is through the main flexible screw mandrel 4 that has been threaded, in the outer ratchet spanner 5 in main flexible screw mandrel 4 lower ends, main flexible screw mandrel 4 times through the secondary screw mandrel 6 that stretches that has been threaded; By the screw thread on main flexible screw mandrel 4 and the secondary flexible screw mandrel 6 suspension hook 7 being produced moves up and down; On carry or transfer insulator string, secondary flexible screw mandrel has suspension hook 76 times, suspension hook 7 is used for connecting and transmits rope.
Operating process:
At first, two operative employees carry and transmit rope and step on tower and hang up properly to the cross-arm place to transmit and restrict, and the terrestrial operation worker reaches this charged for replacement insulator string jig and insulated hanging pole on the tower; Two operative employees cooperate on the tower; This charged for replacement insulator string jig is pressed on the cross-arm bolt U screw through gap 2; Suspension hook 7 is hooked on the lead of insulator string both sides; Move ratchet spanner 5,, tighten up screw mandrel the lead loading is transferred on this charged for replacement insulator string jig through moving on main flexible screw mandrel 4 and the secondary flexible screw mandrel 6; Two operative employees take off the spring pin on insulator and the bowl head at tower to lead horizontal level with action bars, take a bowl head; An operative employee moves ratchet spanner 5; Through moving down of main flexible screw mandrel 4 and secondary flexible screw mandrel 6, lead is moved down 10-15 centimetre, another operation is tied up insulator string and is being transmitted on the rope; The operative employee ties up new insulator string and is transmitting on the rope on the ground; And with tower on operative employee cooperate and take off spring pin old insulator string is reached ground, new insulator passes on the tower, accomplishes the operation of charged for replacement insulator string.

Claims (1)
