Abstract

The invention discloses a tool of suspending an insulated flexible ladder on live wires, solving the problems that a current tool is hard to perform overhead working, is easy to damage seriously, and is difficult in guaranteeing operation effectiveness. The tool is characterized in that the top of a tackle hook head is provided with a groove and a connection hole I, and a separated pull plate is inserted into the groove, and is fixed through a pin I; the head is provided with a groove and a connection hole II, and a guide plate is inserted into the groove, and is in shaft connection through a second pin II; the guide plate is in connection with a suspension power rope through the connection hole II, and the separated pull plate is in connection with a separated power rope through the connection hole I; the tackle hook head is in connection with an insulated pulley through a fixing clamping plate, a connection bolt and a connection screw. The tool is portable, flexible, safe, reliable and practical, is convenient to operate, and can overcome deficiencies of traditional working methods, solve the problem of time and energy waste in suspending an insulated flexible ladder in a hot-line work process, and substantially reduces work personnel labor intensity and hot-line work risks.

Description

Live wire hangs the instrument of insulated flexible ladder
Technical field
The present invention relates to a kind of hanging tool, relate to a kind of instrument hanging insulated flexible ladder on overhead transmission line conductor or rather.
Background technology
At present, all need to hang insulated flexible ladder in service works such as power industry overhead transmission line replacing insulator under electrified, repairing wire, dismounting foreign matters and enter side of wire operation, effectively hanging insulated flexible ladder is the key that can decision enter side of wire operation.The method of conventional suspension insulated flexible ladder has two kinds: one hangs somersault coaster method, operating personnel carries insulating cord, somersault coaster, insulating bar rod-rising tower to cross-arm uses action bars to hang on wire by the somersault coaster with insulation ropes, by somersault coaster, insulated flexible ladder is suspended from wire under ground staff coordinates, action bars is directly used to take off rear freely falling body to ground during disengaging, but along with electric pressure raises, action bars length constantly increases, tower hangs, remove somersault coaster difficulty larger, and dismounting somersault coaster freely falling body very easily damages instrument.Another kind is direct shooting rope method, operating personnel threw wire by a little shooting rope on the ground, little shooting rope traction insulating cord strides across wire, directly promote insulated flexible ladder by drawing insulating cord and hang insulated flexible ladder on wire, but the wire coarse when lifting, whereabouts insulated flexible ladder is very serious to the wearing and tearing of insulating cord, and needing ground operating personnel to coordinate, labour intensity is large.Adopt above two kinds of methods all effectively cannot complete the suspension of insulated flexible ladder.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art provides a kind of live wire to hang the instrument of insulated flexible ladder, simple and practical, overcome that work high above the ground difficulty is large, tool damage is serious, operation effectiveness is difficult to the deficiencies such as guarantee, solve in live line working process and hang insulated flexible ladder and the difficult problem such as to waste time and energy, substantially increase efficiency, reduce operating risk.
The present invention includes and hang dynamic ropes, depart from dynamic ropes, characterized by further comprising coaster gib head, connecting hole, disengaging arm-tie, guide plate, pin, connecting bolt, connecting screw rod, strap, insulating block; Described tackle hook head top-slitting beats connecting hole I, inserts and depart from arm-tie in groove, and depart from arm-tie and fixed by pin I, slotted head beats connecting hole II, inserts guide plate in groove, and guide plate uses pin II axle to connect; Described guide plate is connected with suspension dynamic ropes by connecting hole II, depart from arm-tie is connected with disengaging dynamic ropes by connecting hole I; Described coaster gib head is connected with insulating block by strap, connecting bolt, connecting screw rod.
As shown from the above technical solution, the present invention is light, flexible, safe and reliable, practical, convenient operation in use, the deficiency in traditional work method can be overcome, solve in live line working process the difficult problem hanging insulated flexible ladder and waste time and energy, greatly reduce the labour intensity of operating personnel and the risk of live line working.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the schematic diagram that coaster gib head of the present invention is connected with strap, connecting bolt, connecting screw rod.
In figure, 1A, connecting hole I; 1B, connecting hole II; 2, arm-tie is departed from; 3A, pin I; 3B, pin II; 4, coaster gib head; 5, guide plate; 6, strap; 7, connecting bolt; 8, connecting screw rod; 9, insulating block; 10, dynamic ropes is hung; 11, dynamic ropes is departed from.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
As shown in Figure 1, the present invention includes connecting hole I 1A, connecting hole II 1B, depart from arm-tie 2, pin I 3A, pin II 3B, coaster gib head 4, guide plate 5, strap 6, connecting bolt 7, connecting screw rod 8, insulating block 9, hang dynamic ropes 10, depart from dynamic ropes 11 etc.
Described coaster gib head 4 top-slitting is beaten connecting hole I 1A and is inserted disengaging arm-tie 2, is fixed, disengaging arm-tie 2 can not be rotated by pin I 3A; Slotted head is beaten connecting hole II 1B and is inserted guide plate 5, and connect with pin II 3B axle, namely guide plate 5 can around pin II 3B flexible rotating.
Shown in composition graphs 2, described coaster gib head 4 is connected with insulating block 9 by strap 6, connecting bolt 7 and connecting screw rod 8, and insulating block 9 can reliably rotate around connecting screw rod 8.
Described connecting hole 1A dockingundocking dynamic ropes 11, described connecting hole II 1B connects suspension dynamic ropes 10, and the insulating cord in described insulating block 9 is directly connected with insulated flexible ladder.
When hanging insulated flexible ladder, hanging after dynamic ropes 10 threw wire, traction suspension dynamic ropes 10 is suspended on coaster gib head 4 on wire, then pulls the insulating cord in insulating block 9 can promote insulated flexible ladder to be suspended from wire.During disengaging, by the disengaging pulling the insulating cord in insulating block 9 to complete insulated flexible ladder, the disengaging then by pulling the disengaging dynamic ropes 11 departing from arm-tie 2 connection easily can complete coaster gib head 4 and live wire.
