Description
Technical field
The present invention relates to electrical network and hot line maintenance technical field, particularly a kind of charged for replacement 220kV narrow base tower strain insulator string instrument.
Background technology
Along with socioeconomic development, society is increasing for the demand of electric power, promotes electrical network scale constantly to expand, and aerial line transmission is as the main body mode of current power transmission, and line size the most constantly increases.And along with the quickening of urbanization process, the more and more aobvious anxiety of land resource, conventional typical angle steel tower busy line channel width and steel tower are big with opening, it is impossible to adapt to the present situation of developed area shortage of land resource.But according to steel pipe pole, although the requirement reducing floor space, but steel pipe pole circuit can be met, use condition requires high than steel tower, and processing transport difficulty is big, and group is vertical needs heavy mechanical equipment, high to job site environmental requirement, construction costs is big, is unfavorable for operation maintenance.
On this basis, the narrow base tower as a example by narrow base steel tube tower arises at the historic moment.Compared to conventional angle steel ferrum, steel tube tower, narrow base steel tube tower has compact firm, the advantage such as the exhibition of tower body arm is compact, line holding space is few of floor space turriform little, overall, increases circuit construction project the most in recent years newly and increasingly tends to use such turriform.
Along with the society's continuous lifting to electric power degree of dependence, it suffers from great requirement for the quality of power supply and continued power, once having a power failure and will cause huge economic loss and social effect, therefore service without power-off is safeguarded has become the conventional means that grid maintenance is safeguarded.But narrow base steel tube tower is due to features such as tower body own are compact, arm exhibition is short, and the operation gap that conventional charged operational method requires cannot meet；It may be said that the service without power-off maintenance aspect almost blank field on narrow base tower.
The use of the newest narrow base tower, its incident New insulated configures, i.e. double insulator, one end is triangle yoke plate, and the other end is right angle yoke plate, and traditional broadsword fixture and wing type clamp apparatus cannot use thereon.At least need two groups of devices are installed between the general same group of yoke plate of the existing device for charged changing tension-resisting insulator, structure is complicated, load and unload loaded down with trivial details, and attachment structure is connected with yoke plate by screw, therefore intensity is low relatively, easily causing potential safety hazard due to loosened screw, security reliability is low, and cannot meet the safety requirements in its operation process for some narrow base tower.
Summary of the invention
The main object of the present invention is the shortcoming overcoming prior art, a kind of simple in construction is provided, disassembled for transport can be realized, easily install and operation, can reduce service work difficulty, improve efficiency, intensity is high, security reliability is high, and can effectively meet the charged for replacement 220kV narrow base tower strain insulator string instrument of safety requirements during narrow base tower livewire work.
The present invention adopts the following technical scheme that
A kind of charged for replacement 220kV narrow base tower strain insulator string instrument, by the triangle link plate clamping tool in order to connect triangle yoke plate, insulation pull-rod, hydraulic screw rod and removably connecting composition in order to connect the right angle link plate clamping tool of right angle yoke plate, described insulation pull-rod is connected between triangle link plate clamping tool and right angle link plate clamping tool by a hydraulic screw rod, described triangle link plate clamping tool is respectively formed double plate structure for the one end and right angle link plate clamping tool connecting triangle yoke plate for the one end connecting right angle yoke plate, triangle yoke plate can be folded in and fix therebetween by the double plate of triangle link plate clamping tool, right angle yoke plate can be folded in and fix therebetween by the double plate of right angle link plate clamping tool.
Further, described triangle link plate clamping tool, hydraulic screw rod, insulation pull-rod and right angle link plate clamping tool are sequentially removably connected by securing member.
Further, described triangle link plate clamping tool connects one end of triangle yoke plate and is formed with the first train wheel bridge and the first lower plate, can triangle yoke plate be folded in therebetween, on first train wheel bridge and the first lower plate, correspondence offers two pin-and-holes matched with fixing hole on triangle yoke plate respectively, can be locked on triangle yoke plate by triangle link plate clamping tool by two movable latch.
Further, described right angle link plate clamping tool connects one end of right angle yoke plate and is formed with the second train wheel bridge and the second lower plate, can right angle yoke plate be folded in therebetween, second train wheel bridge and the second lower plate end correspondence respectively offer two pin-and-holes, can be locked on right angle yoke plate by right angle link plate clamping tool by two movable latch.
Further, being also arranged with a regulation block between described right angle yoke plate and right angle link plate clamping tool end, described regulation block is formed with a draw-in groove, can be arranged in the movable latch being arranged on right angle link plate clamping tool end.
Further, described triangle link plate clamping tool is fixed on triangle yoke plate centre position, and right angle link plate clamping tool is fixed on yoke plate centre position, right angle.
From the above-mentioned description of this invention, compared with prior art, the invention has the beneficial effects as follows: triangle link plate clamping tool and right angle link plate clamping tool are connected to triangle yoke plate and yoke plate centre position, right angle, only need that one group of instrument is installed and can complete the charged for replacement operation of its both sides insulator chain, simple in construction, easily install and operation, the work difficulty of service work personnel can be reduced, shorten working hours, improve efficiency, and disassembled for transport can be realized, simultaneously, triangle link plate clamping tool uses double plate structure with right angle link plate clamping tool, locked and connected with triangle yoke plate and right angle yoke plate by movable latch, it is more firm to connect, intensity is high, and balance is good, sliding can be avoided the occurrence of rock, get loose and drop or " cannot get up, under do not go " etc. bad phenomenon, potential safety hazard can be reduced, effectively meet the safety requirements during narrow base tower livewire work.Therefore, safe hotline maintenance can be realized, reduce and stop power transmission operational ton and the change of whole power system operating mode, not only can realize huge economic benefit, also be greatly improved the security reliability of operation of power networks.
