Abstract
The invention relates to an overhaul device for power supply equipment, in particular to a lifting ladder hook for insulated pulling materials. The lifting ladder hook can be used for solving the problems of on-scene overhaul and the like. The invention relates to two varieties: 1, an insulated force bearing rod is provided with conductor hooks, wherein the main principle is that two conductor hooks are arranged on the lower end of the insulated force bearing rod according to the twin bundled conductor distance, and can lift a conductor after hooking the conductor, and the equipment is used for solving the problem of generality of power failure operation and live-wire operation and solving the problem that a lifting tool for power failure operation cannot be used for lifting the conductor under the condition of live-wire operation; and 2, a step tread is arranged on the insulated force bearing rod, wherein the main principle is that the step tread for workers to go up and down an insulator string is arranged on the insulated force bearing rod, and the equipment is used for solving the problem that a ladder needs to be bound when the workers go up and down the insulator string, and reduces the number of tools performing the same operation.
Description
Technical field
The present invention relates to a kind of maintenance utensil of power supply unit, specifically a kind of lifting ladder hook of insulated pulling materials can be used to solve difficult problems such as site examining and repairing.
Background technology
When using general tool transposing straight line insulator string, the instrument of use is many, the weight of instrument is also heavier, and staff's labour intensity is also than higher; And the power failure operation need be used different Work tools with live line working.These have all brought very big trouble to construction working.So be badly in need of a kind of labour intensity that can alleviate the staff of development, the security risk that exists in the reduction work, the outfit quantity of Work tool in the minimizing work, effectively raising transfers a bottle operating efficiency, while can be applicable to that the instrument of power failure operation and live line working overhauls a difficult problem to solve.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned prior art, a kind of lifting ladder hook of insulated pulling materials is provided, with the efficient of effective raising work on it, the fail safe of safeguard work.
According to technical scheme provided by the invention, several are set on insulation load bar equably can be provided for promoting the lifting device of insulation load bar in the upper end of insulation load bar for staff's insulation step up and down; Bottom at insulation load bar is provided with two wire hooks according to the double bundle conductor spacing.
Described insulation step is straggly to be arranged on the insulation load bar.In described lifting device, plane bearing is arranged on clamping plate, on plane bearing, connect ratchet mechanism, on the ratchet of described ratchet mechanism, connect the handle be used for rotating ratchet, at the inwall of the ratchet mechanism anti-torsion wire bar that is spirally connected.
Advantage of the present invention is: 1, integrate lifting lead, staff insulator string function up and down; 2, simple in structure, compact, in light weight; 3, be applicable to line outage operation and live line working simultaneously; Lack than the required staff of conventional instrument when 4, using; 5, instrument is easy to use, and labour intensity can reduce a staff.
Description of drawings
Fig. 1 is a structure chart of the present invention.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is anti-torsion wire bar structure chart.
Embodiment
As shown in the figure: several are set on insulation load bar 4 equably can be provided for promoting the lifting device of insulation load bar 4 in the upper end of insulation load bar 4 for staff's insulation step 3 up and down; Bottom at insulation load bar 4 is provided with two wire hooks 5 according to the double bundle conductor spacing.Described insulation step 3 straggly being arranged on the insulation load bar 4.
In described lifting device, plane bearing 10 is arranged on clamping plate 9, on plane bearing 10, connect ratchet mechanism 7, on the ratchet of described ratchet mechanism, connect the handle 8 that is used for rotating ratchet, at the inwall of the ratchet mechanism anti-torsion wire bar 6 that is spirally connected.Lower end at anti-torsion wire bar 6 is provided with connecting hole 11.Upper end at insulation load bar 4 is provided with brace 2, on described brace 2 pin hole 1 is set.When needs interconnect axle together the time with described lifting device and described insulation load bar 4, latch inserted in described connecting hole 11 and the pin hole 1 get final product.
When being used for the double bundle conductor power failure transposing composite insulation period of the day from 11 p.m. to 1 a.m, the wire hook 5 of load bar 4 lower ends of will insulating earlier catches on two root leads in the transmission line; Lifting device utilizes clamping plate 9 to be fixedly mounted on the iron tower cross-arm, and the upper end of the load bar 4 that will insulate again and the lower end of the anti-torsion wire bar 6 in the lifting device utilize latch to interconnect; Grasp the handle 8 in the lifting device then, and spur handle 8 back and forth,, drive anti-torsion wire bar 6 and rotate by ratchet mechanism 7; After rotating anti-torsion wire bar 6, drive insulation load bar 4 and two wire hooks 5 and two root leads and move up together, promote two root leads.Operating personnel can be moved downward near the sub-conductor along the insulation step 3 on the insulation load bar 4, change the composite insulation substring again.So-called double bundle conductor is meant: in order to reduce corona reducing the wastage and to the interference of radio etc., and in order to reduce reactance to improve the ability of circuit transmission of electric energy, a phase conductor of employing has two root leads, the lead that has conductor spacer to connect between sub-conductor.Described anti-torsion wire thick stick 6 is different with common leading screw, and this leading screw can prevent twisting after stressed, be a kind of standard component, can outsourcing.
When being used for the charged earth potential of the double bundle conductor transposing composite insulation period of the day from 11 p.m. to 1 a.m: the wire hook 5 on the load bar 4 that will insulate earlier catches on lead, makes two wire hooks 5 reliably catch on two root leads in the transmission line respectively; Lifting device utilizes clamping plate 9 to be fixedly mounted on the iron tower cross-arm, and the upper end of the load bar 4 that will insulate again and the lower end of the anti-torsion wire bar 6 in the lifting device utilize latch to interconnect; Grasp handle 8 then, and spur handle 8 back and forth,, drive anti-torsion wire bar 6 and rotate by ratchet mechanism 7; After rotating anti-torsion wire bar 6, drive insulation load bar 4 and two wire hooks 5 and two root leads and move up together, promote two root leads.Because sub-conductor at this time is charged, so operating personnel can not can only use insulating bar transposing composite insulation substring along insulation load bar 4 near described sub-conductor.Described charged earth potential working is a kind of mode of live line working, and during operation, operating personnel are under ground (zero) potential state, use insulating tool indirect contact charging equipment.
