Description
Technical field
The utility model relates to electrical network and hot line maintenance technical field, particularly a kind of right angle link plate clamping tool for live replacement of 220 kV tension-resistant insulator string.
Background technology
Along with socioeconomic development, society is increasing for the demand of electric power, is impelling electrical network scale constantly to expand, the main body mode that overhead wire transmission is carried as current electric power, and line size also constantly increases thereupon.And along with the quickening of urbanization process, land resource is more and more aobvious nervous, conventional typical angle steel tower busy line channel width and steel tower are large with opening, present situation that can not adapt to economic development developed regions shortage of land resource.If but adopt steel pipe pole, although can meet the requirement that reduces floor space, steel pipe pole circuit, service condition requires high than steel tower, processing transport difficulty is large, the vertical heavy mechanical equipment that needs of group, high to job site environmental requirement, project cost is large, is unfavorable for operation maintenance.
On this basis, arise at the historic moment taking narrow base steel tube tower as the narrow base tower of example.Compared to conventional angle steel iron, steel tube tower, narrow base steel tube tower has the advantages such as little, the overall turriform of floor space is compact firmly, the exhibition of tower body arm is compact, line holding space is few, and therefore newly-increased circuit construction project more and more tends to use such turriform in recent years.
Along with the continuous lifting of society to electric power degree of dependence, it has great requirement for the quality of power supply and continued power, will cause huge economic loss and social effect once have a power failure, therefore service without power-off is safeguarded has become the conventional means that grid maintenance is safeguarded.But narrow base steel tube tower is because tower body compactness own, arm are opened up the features such as short, and the operation gap that conventional charged operational method requires cannot meet; Can say that service without power-off on narrow base tower safeguards that aspect is almost a blank field.
The use of at present new narrow base tower, it is followed and has carried out New insulated configuration, and traditional machete jig and wing type clamp apparatus cannot use thereon.Between the general same group of yoke plate of the existing device for charged changing tension-resisting insulator, at least need to install two groups of devices, complex structure, load and unload loaded down with trivial details, and syndeton is connected with yoke plate by screw, therefore intensity is low, easily, because loosened screw causes potential safety hazard, security reliability is low, and cannot meet the safety requirements in its operation process for some narrow base tower.
Utility model content
Main purpose of the present utility model is the shortcoming that overcomes prior art, provide a kind of simple in structure, easily install and operation, can reduce service work difficulty, raise the efficiency, intensity is high, and security reliability is high, and can effectively meet the right angle link plate clamping tool for live replacement of 220 kV tension-resistant insulator string of the safety requirements in narrow base tower live line working process.
The utility model adopts following technical scheme:
For the right angle link plate clamping tool of live replacement of 220 kV tension-resistant insulator string, described right angle link plate clamping tool is removably connected to insulation pull-rod one end for connecting right angle yoke plate, it forms double plate structure for the one end that connects right angle yoke plate, right angle yoke plate can be folded in fixing therebetween, on described insulation pull-rod, be also provided with a hydraulic screw rod, one end that described right angle link plate clamping tool connects right angle yoke plate is formed with train wheel bridge and lower plate, right angle yoke plate can be folded in therebetween, train wheel bridge and lower plate end respectively correspondence offer two pin-and-holes, can right angle link plate clamping tool be locked on right angle yoke plate by two movable latch.
Further, between described right angle yoke plate and right angle link plate clamping tool end, be also arranged with an adjusting block, described adjusting block is formed with a draw-in groove, can be arranged in the movable latch that is arranged on right angle link plate clamping tool end.
Further, described right angle link plate clamping tool is fixed on yoke plate centre position, right angle.
From above-mentioned to description of the present utility model, compared with prior art, the beneficial effects of the utility model are: right angle link plate clamping tool is connected in yoke plate centre position, right angle, two right angle link plate clamping tools are connected and are installed between two right angle yoke plates by insulation pull-rod, can complete the charged for replacement operation of its both sides insulator string, only need to install one group of instrument, simple in structure, easily install and operation, can reduce service work personnel's work difficulty, shorten working hours, raise the efficiency, simultaneously, right angle link plate clamping tool adopts double plate structure, lock and connect by movable latch and right angle yoke plate, it is more firm to connect, intensity is high, and balance is good, can avoid occurring that slippage rocks, get loose and drop or " cannot get up, under do not go " etc. bad phenomenon, can reduce potential safety hazard, effectively meet the safety requirements in narrow base tower live line working process.Therefore, can realize safe hotline maintenance, reduce the change that stops power transmission operational ton and whole power system operating mode, not only can realize huge economic benefit, also can greatly improve the security reliability of operation of power networks.
