Abstract
The invention relates to a maintenance tool, namely a hoisting support for maintenance of an isolating switch. It comprises a vertical rod, and a hanging hole for hanging a pulley is arranged at the upper end of the vertical rod. A base is arranged below the vertical rod, a screw rod is respectively arranged on the bases at two sides of the vertical rod, and a pressing plate capable of moving up and down and adjusting is arranged on the base; the pressing plate is provided with three holes which correspondingly penetrate through the two screw rods and the upright rod, and the screw rods are provided with locking screw caps. Through shortening pole length and changing pole fixed mode, weight has been alleviateed, the on-the-spot fixed connection of being convenient for, and is light nimble, tear quick convenience, safe and reliable has alleviateed working strength, has stopped many people in the past and has overhauld the situation of a set of switch, has improved labor efficiency, reduces the manpower expenditure, and work efficiency is high, has guaranteed the maintenance quality.
Description
Technical field
The present invention relates to a kind of maintenance frock, i.e. isolating switch maintenance hoisting bracket.
Background technology
In the prior art, in the electric power system 66kV isolating switch overhaul process, adopt aluminium alloy pole or inspection platform to carry out.Utilize the operation of aluminium alloy pole, pole is longer, and weight is big, needs 8 people usually, fixing armful of four backguys doing, and the also bad choosing in the position of backguy is not easy control, can't guarantee safe distance, causes electric shock easily.The pole height is not easy control, and the upright pole of group is abnormally dangerous, causes the phenomenon of falling the bar easily, and very near from charging equipment, and dangerous especially when moving pole, this method is not suitable in the nearer regional work of charging equipment (referring to Fig. 1).Use pole to lift, poor stability, dangerous big, work danger occurs often, and repair quality is qualified low, service kit complicated operation, inefficiency.The inspection platform volume is big, and weight is big, and complicacy is installed, and needs many people cooperate installation, and the time consuming time is long, and the eminence action is inconvenient.These two kinds of operational methods, the activity duration is long, needs personnel many, and is near with charging equipment, dangerous big, causes operating efficiency low, can not satisfy need of work.And because personnel are many, the activity duration is long, and the staff is prone to produce physical fatigue, causes danger easily, is unfavorable for safety in production.
Summary of the invention
The objective of the invention is provides a kind of quick-mounting soon to above-mentioned deficiency, tears open, improves the isolating switch maintenance hoisting bracket of service work efficient.
Technical solution of the present invention is: the vertical rod of isolating switch maintenance hoisting bracket, there is hanging hole or the hook of hanging pulley the vertical rod upper end.Base is arranged below the vertical rod, a screw rod is respectively arranged on the base of vertical rod both sides, the pressing plate that can move up and down adjustment is arranged on the base; Three holes are arranged on the pressing plate, and correspondence is passed two screw rods and vertical rod, and lock nut is arranged on the screw rod.
Advantage of the present invention is: 1, shorten pole length, weight reduction changes the pole fixed form, is convenient to fixed in place and connects, and light and flexible is torn open quick and convenient, safe and reliable.2, the saving personnel have alleviated working strength, have stopped the situation that many in the past people overhaul one group of switch, have improved efficiency, and safety also is guaranteed.3, shorten interruption duration, reduce the manpower expenditure, high efficiency has guaranteed repair quality.
To combine accompanying drawing that execution mode of the present invention is described in further detail below.
Description of drawings
Fig. 1 is a pole user mode structure diagram in the prior art.
Fig. 2 is a structure diagram of the present invention.
Fig. 3 is a user mode structure diagram of the present invention.
Embodiment
Referring to Fig. 2, isolating switch maintenance hoisting bracket comprises vertical rod, and vertical rod is made up of the following pillar 1 and the body of rod 2 that inserts in the pillar 1, and this two body structure is convenient to assembling.There is the hanging hole 3 of hanging sister block the body of rod 2 upper ends.The base 4 that has channel-section steel to make below the pillar 1 has the pressing plate 5 that can move up and down adjustment on the base 4; A screw rod 6 is respectively arranged on the base 4 of vertical rod both sides, three holes are arranged on the pressing plate 5, correspondence is passed two screw rods 6 and pillar 1, and lock nut 7 is arranged on the screw rod 6, is used for clamping between pressing plate 5 and the base 4.Pillar 1 upper end has group to prick the hanging ring 8 of maintainer's waist rope.
Referring to Fig. 3, utilize the channel-section steel of isolating switch base to fix the base 4 of hoisting bracket.Isolating switch maintenance hoisting bracket is clamped on the channel-section steel of equipment base angle through pressing plate 5, base 4.
Referring to Fig. 1,9-is a pole, and 10-is backguy, and 11-is the position of pole when moving for the second time.
Claims (3)
1. an isolating switch maintenance hoisting bracket comprises vertical rod, and there is hanging hole (3) or the hook of hanging pulley the vertical rod upper end, it is characterized in that below the vertical rod base (4) being arranged, and a screw rod (6) is respectively arranged on the base of vertical rod both sides (4); The pressing plate (5) that can move up and down adjustment is arranged on the base (4), three holes are arranged on the pressing plate (5), correspondence is passed two screw rods (6) and vertical rod, and lock nut (7) is arranged on the screw rod (6).
2. according to the described isolating switch of claim 1 maintenance hoisting bracket, it is characterized in that vertical rod is made up of following pillar (1) body of rod (2) interior with inserting pillar (1).
