Abstract
The invention discloses a power transmission line weight pallet. The power transmission line weight pallet comprises two transverse supporting plates, two first longitudinal supporting plates and two second longitudinal supporting plates, wherein the six supporting plates are symmetrically installed to form a #-shaped structure; the two transverse supporting plates are horizontally arranged, the two first longitudinal supporting plates are vertically in screwed connection with the lower surfaces of the two transverse supporting plates, side edges of the two second longitudinal supporting plates are provided with long-strip-shaped through grooves, and the second longitudinal supporting plates are respectively in screwed connection with side edges of the corresponding first longitudinal supporting plates through cooperation between bolts and the long-strip-shaped through grooves. The weight pallet provided by the invention is small in overall structure and simple to operate, is highly portable and firm, lifts a jumper wire insulator string with a weight through cooperation with other response live-line operation tools and utensils, breaks the trouble of power failure maintenance-induced energy loss and economic loss of users from various circles of the society, caused by incapability of eliminating defects due to lack of a correlation weight pallet by a conventional 500kV weight type jumper wire string, mitigates power supply pressure and improves the demand-supply contradiction.
Description
Technical field
The present invention relates to a kind of transmission line weight pallet, belong to transmission line technical field.
Background technology
Electric power is a national energy lifeblood, is the power producer of a social progress.Along with the fast development of economy, the demand of every profession and trade to electric power also increases year by year, unprecedented pressure is brought to supply of electric power, supply falls short of demand, so the reliability of transmission line should be improved constantly, for avoiding line outage, to alleviate power supply pressure, reduce economic loss and electric energy loss, extensively carry out service without power-off and seem particularly important.
Along with the further maturation of technology patrolled and examined by the application of transmission line status detection technique and helicopter, enriched polling transmission line means, transmission line equipment hidden danger discovery rate progressively promotes, and also more to become specific aim and correctness to the discovery of hidden trouble of equipment simultaneously.Patrol and examine in process at Power Bureau, Shaoxing City's helicopter of 2013 and just found 2 place 500kV transmission line jumper string composite insulator fever phenomenons, and this 2 place jumper string is the middle phase weight type jumper string of JT2 turriform, wherein place's composite insulator heating temperature difference has reached 18.7 DEG C, belong to critical defect, all may generate heat because of composite insulator core bar at any time, mechanical strength is caused to decline and insulator string occurs fall string accident, the safe and stable operation of serious threat electrical network.And this circuit is again important hingeline road, if changed by normally carrying out power failure, be restricted making multiple electric substations of this area power, the power supply reliability of whole electrical network also will be a greater impact, therefore the live line working scheme of this type of hidden danger process of research is badly in need of, both will play positive role to raising power supply reliability, guarantee electric power netting safe running, also provide concrete practical experience by the expansion for live line working project.
But 500kV jumper string insulator is when having a weight, adopt general Work tool to be difficult to promote insulator in the case of not charged, because the existence of weight, conductors on quad bundled is difficult to as hoist point, and weight not having easy colligation firmly local, this has buried hidden danger to upkeep operation.
In view of this, the present inventor studies this, and develop a kind of transmission line weight pallet specially, this case produces thus.
Summary of the invention
The object of this invention is to provide a kind of transmission line weight pallet, jumper string weight can be held up, coordinate with other live working tools and wire jumper insulator string is promoted, conveniently carry out relevant service work.
To achieve these goals, solution of the present invention is:
A kind of transmission line weight pallet, comprise 2 blocks of horizontal supporting plates, 2 piece of first longitudinal supporting plate and 2 piece of second longitudinal supporting plate, above-mentioned 6 pieces of supporting plate symmetries are mounted to " well " font structure; Wherein, described 2 pieces of horizontal pallets level are arranged, 2 piece of first longitudinal supporting plate is vertically screwed onto the lower surface of 2 blocks of horizontal supporting plates, described 2 piece of second longitudinal supporting plate side is provided with strip groove, second longitudinal supporting plate, by the cooperation of bolt and strip groove, is screwed onto first corresponding longitudinal supporting plate side respectively.
As preferably, the two ends of described horizontal supporting plate are equipped with fixed head, described fixed head bottom vertical is fixed on horizontal supporting plate, fixed head upper end is provided with through hole, in described through hole, adjusting bolt is installed, the fixed broadband of horizontal supporting plate can be adjusted by adjusting bolt, and then adapt to the weight of different size.
