Abstract
The utility model relates to an overhaul tooling, namely a hoisting support for overhaul of an isolating switch. The hoisting support comprises an upright rod, wherein a hanging hole for hanging a pulley is arranged at the upper end of the upright rod. A base is arranged below the upright rod, screw rods are respectively arranged on the base on the two sides of the upright rod, and a pressure plate which can be moved and adjusted up and down is arranged on the base; and three holes are arranged on the pressure plate, the two screw rods and the upright rod penetrate the three holes correspondingly, and a locking screw cap is arranged on each screw rod. By shortening the length of a derrick and changing the fixing way of the derrick, the weight is reduced, the on-site fixed connection is facilitated, and the hoisting support has the advantages of portability, flexibility, fast and convenient detachment, safety, reliability and high working efficiency, and can reduce working strength, avoid the situation that overhauling a group of switches by multiple persons in the past, improve labor efficiency, reduce manpower expenditure and ensure overhaul quality.
Description
Technical field
The utility model 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.
The utility model content
The purpose of the utility model is a kind of quick-mounting soon is provided, tears open to above-mentioned deficiency, and the isolating switch that improves service work efficient overhauls hoisting bracket.
The technical solution of the utility model 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.
The utility model has the advantages that: 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 the execution mode of the utility model 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 the utility model structure diagram.
Fig. 3 is the utility model user mode structure diagram.
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).
3. according to claim 1 or 2 described isolating switch maintenance hoisting brackets, it is characterized in that there is hanging ring (8) at the vertical rod middle part.
