Description

Isolating switch post insulator boom hoisting

Technical field

The utility model relates to a kind of boom hoisting.

Background technology

Isolating switch is a kind of important power equipment that the power supply department substation uses, and isolating switch needed to overhaul after operation a period of time.To overhaul isolating switch, then need and to carry out after post insulator dismounting, the transfer.The transfer to post insulator does not at present have special-purpose lifting appliance, can only be with common crane.Because the comparatively dense that the post insulator of present most of transformer station is arranged, and just there is not access path during the design that has, this just makes with the difficulty of huger common crane lifting post insulator bigger, for preventing that the crane lifting mistiming from bumping charging equipment, adjacent charging equipment and bus all must just can carry out lifting work under situation about having a power failure.As seen, adopt common crane lifting post insulator to exist the shortcoming that operating efficiency is low, influence normal power supply.

The utility model content

The purpose of this utility model is to provide a kind of isolating switch post insulator boom hoisting, and is easy to operate, flexible when lifting by crane the post insulator of isolating switch with its, and adjacent charging equipment and bus need do not had a power failure.

For achieving the above object, the utility model adopts following scheme: isolating switch post insulator boom hoisting, have on the base plate of installing hole and be fixed with a base, the vertical shaft that is with bearing is contained on the base, be connected with column on the vertical shaft, rotating shaft is equipped with at middle part at column, one end of rotating shaft is equipped with reel, be fixed with an arm in the upper end of column, a fixed pulley respectively is equipped with at the two ends of arm, and the rope that is wound with on the reel is on two fixed pulleys, the fixed pulley that rope is crossed the arm front end extends downwards, and the front end of rope is connected with arm, and rope is on the leading portion of arm below has born a movable pulley, is connected with hanging part in the bottom of movable pulley.

By such scheme as seen, base plate is fixed on the framework of isolating switch, the rope of binding post insulator is connected with hanging part, handle the rotating shaft rotation, roll up, put rope, can realize the lifting of post insulator and put down by reel; In addition, by the rotation of vertical shaft, can select suitable lifting position.

The utility model is simple and reasonable for structure, cost of manufacture is low, it is as lifting isolating switch post insulator, have characteristics easy to use, flexible, that lifting speed fast, saving is artificial, and employing of the present utility model, can be implemented under the charged situation of bus and adjacent equipment, finish the lifting of post insulator, and then reduce interruption duration.

Embodiment

Further specify the utility model below in conjunction with embodiment and accompanying drawing.

Referring to Fig. 1

In the boom hoisting that the utility model provides, have on the base plate 1 of installing hole 1a and be fixed with a base 2, the vertical shaft 3 that is with bearing is contained on the base 2, be connected with column 4 by latch 5 on the vertical shaft 3, at the middle part of column 4 rotating shaft 7 is housed, one end of rotating shaft 7 is equipped with reel 6, be fixed with an arm 11 in the upper end of column 4, a fixed pulley 9 respectively is equipped with at the two ends of arm 11, the rope 8 that is wound with on the reel 6 is on two fixed pulleys 9, and the fixed pulley 9 that rope 8 is crossed arm 11 front ends extends downwards, and the front end of rope 8 is connected with the bottom of arm 11, rope 8 is on the leading portion of arm 11 belows has born a movable pulley 12, is connected with hanging part in the bottom of movable pulley.Hanging part is made up of a snap ring 13 and the bolt 14 with opening, and the peristome that bolt 14 is through snap ring 13 seals it.Be fixed with a support wheel 10 at the middle part of arm 11 upsides, rope 8 is on this support wheel 10.

Be fixed with a bearing pedestal 18 at the middle part of column 4, rotating shaft 7 is contained in the bearing pedestal 18, and an end of bearing pedestal 18 connects with a casing 15, casing 15 is passed in rotating shaft 7, be positioned in rotating shaft 7 on the axle journal of casing 15 and be connected with worm gear 17, worm screw 16 is housed, worm gear 17 and worm screw 16 engagements in the casing 1.

Referring to Fig. 2

The end of worm screw 16 stretches out outside the casing 15, and worm screw 16 is positioned on casing 15 end outward and is connected with crank 27.

Referring to Fig. 1, Fig. 3, Fig. 4

Be fixed with a back-up ring 19 on the vertical shaft 3, on back-up ring 19, be fixed with two pairs of bolts 20, on base plate 1, be hinged with two hooks 21 that cooperate with bolt 20.When this boom hoisting carries out slinging work, the gap 21a that links up with 21 front ends is stuck on the bolt 20, can limit the rotation of vertical shaft 3.
