The present invention has safe overhaul, convenient operation, high material intensity, light weight, and strong stability, thereby reducing live-line overhaul difficulty of 500kv large span overhead ground wire, and increasing working efficiency.
Description
Technical field
The present invention relates to the electric power apparatus examination device, a kind of large span overhead ground wire live-line overhaul car is used for 500 kilovolts big of power departments and crosses over transmission line overhead ground wire or built on stilts line maintenance, equipment and the facility maintenance of common 500 kilovolts of transmission lines.
Background technology
At present, domestic employed operation tool is simple type for the 500 kilovolts big hotline maintenances of crossing over overhead ground wire, and execute-in-place is poor, and adaptive capacity is not strong.The simple type driving is not steady in the process of moving, and it is very difficult to break the barriers, and needs to consume very big muscle power.The simple type driving can not make the staff carry out work under safety, balance, stable status.
The special-purpose manned driving of the big leap overhead ground wire of existing a kind of actual simple type that uses is made of band iron, can cross under the power-off condition big basically, uses in the enterprising enforcement of overhead ground wire.But the maintainer rides on the driving, for keeping driving balance and stable, need use lanyard below driving, and be drawn below by another person.When stockbridge damper, damping wire and the wire clamp, need that the maintainer firmly impacts moving runner on the driving, physical demands is big.The staff takes driving, and its weight is in driving one side, and human body is difficult to balance.This driving does not have and becomes sloping function, personnel can not around the conversion moving position.This makes corresponding work exist big, the ineffective problem of operation easier.
Summary of the invention
The present invention is for avoiding above-mentioned existing in prior technology weak point, provide a kind of maintenance safety, easy to operate, intensity is high, in light weight, stablize strong large span overhead ground wire live-line overhaul driving, to reduce by 500 kilovolts big hotline maintenance operation easier of crossing over overhead ground wire, increase work efficiency.
Technical solution problem of the present invention adopts following technical scheme:
The design feature of large span overhead ground wire live-line overhaul driving of the present invention is rectangle to be set take advantage of people's framework, and it is extensible pedal that rectangle is taken advantage of the bottom of people's framework, and the top has front beam and the rear cross beam that be arranged in parallel; Between front beam and rear cross beam, the outstanding longeron of the pair of parallel that is inclined to set combination, described outstanding longeron is supported on the overhead ground wire with the race buckle by front-wheel and tail wheel; Leverage is set, and the tail end of lever and the rear end of outstanding longeron are hinged, and the front end of lever takes advantage of people's framework place one side to extend as manual depression bar to described rectangle, are that rotating shaft is provided with auxiliary wheel with the rotating fulcrum of lever, and described auxiliary wheel is supported on the overhead ground wire; Rear end at described outstanding longeron is provided with towing point.
The design feature of large span overhead ground wire live-line overhaul driving of the present invention also is:
In described outstanding longeron, sliding rail is set along the length direction that hangs longeron; Front beam is arranged in sliding rail, and two crossbeam side levers that are used to support front beam are the hinge bar that rectangle is taken advantage of people's frame roof, and described two crossbeam side levers are taken advantage of on people's framework at rectangle with a pair of strut of adjustable in length and formed gusseted.
Rectangle is set takes advantage of top, the both sides frame of people's framework to be the adjustable guardrail of level for can outwards overturning.
In service, during by obstacles such as stockbridge dampers, damping wire clamp, its front-wheel often passes through easily at driving, and difficulty is to be trailing wheel.Auxiliary wheel is set among the present invention, and leverage is set, the exert oneself front end of depress lever of operator promptly presses down manual depression bar, and making with the auxiliary wheel is fulcrum, lifts tail wheel slightly, makes tail wheel be broken the barriers smoothly.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, maintenance safety of the present invention, easy to operate, intensity is high, in light weight, stability is strong.
2, the present invention can be widely used in:
A, cross under the charging operation situation, vibration measuring equipment is installed on the position of stipulating on the overhead ground wire big.
B, cross under the charging operation situation, overhead ground wire, vibrationproof facility are checked, the parts that go wrong are overhauled big.
C, be applied on the crossover tower of any structure.
D, be applied on the general circuit.
