Description

Transformer station's Simple lifter

Technical field

The utility model relates to a kind of transformer station simple and easy hoisting equipment, specifically a kind of transformer station Simple lifter.

Background technology

In order to the power delivery that power plant is sent is to place far away, voltage must be raised, make it become high-tension electricity, on demand voltage be reduced after near user again, the work of this buck/boost has come by transformer station.Transformer station is the assembly place of transmission and disttrbution, be voltage of transformation in electric power system, acceptance and distribution electric energy, the flow direction of control electric power and the electric power facility of adjustment voltage, the capital equipment of transformer station comprises the switchgear such as transformer, instrument transformer, thunder resisting equipment and circuit breaker, isolating switch, on-load switch, high-tension fuse.

Because transformer station is mostly arranged on open air, its equipment can be damaged by the impact of varying environment, therefore needs often to carry out inspection and maintenance to the equipment in transformer station.In the service work of transformer station's reality, usually utilize crane to carry out the replacing of the heavier equipment such as switch, voltage transformer or current transformer, but crane operation not only operation task weight, formality is loaded down with trivial details, and power failure area is large, cost is high.

Utility model content

The purpose of this utility model is just to provide a kind of transformer station Simple lifter, to solve the problem that power failure area is large, operation task heavy and cost is high that existing crane operation exists.

The utility model is achieved in that a kind of transformer station Simple lifter, includes:

Standpipe, by being connected on the transverse arm of riser upper outward, suspension type is fixedly connected on the supporting framework of transformer station;

Swing bar is tubular body, is inclined at the upper end of described standpipe, in order to change the horizontal level of lifting object; Be connected to the insertion pipe for grafting standpipe in the lower port of swing bar, be connected to pulley in the upper port of swing bar; And

Manual hoist structure, is arranged on the lower end of described standpipe, for being elevated weight; After standpipe, described insertion pipe and described swing bar described in steel wire penetrating in manual hoist structure, stretched out by the upper port of described swing bar, and at connecting shackle after described pulley.

The utility model is provided with deep floor in the junction of described insertion pipe and described swing bar.

The utility model is provided with deep floor in the junction of described standpipe and described transverse arm.

During use, first the transverse arm of bracing frame is fixed on pinnacled framework, then the insertion pipe of swing bar is plugged on the riser top ends of bracing frame, make it be pressed in the slideway of pulley steel wire rope pull-out, i.e. the installation of complete cost apparatus; After installing, with the hook weight (switchgear, current transformer, voltage transformer etc.) of steel cord ends, rotating swing bar makes weight go to the fixed station departed from supporting framework, the jack shaft of rotation manual hoisting mechanism, weight is declined gradually until kiss the earth, then suspension hook is removed from weight.Same, also by the heavy lift of lower to eminence, namely can use hook weight, rotate backward jack shaft, make weight increase gradually, after heavy lift to eminence, rotate swing bar and make weight go on fixed mesa, then suspension hook is removed from weight.

The utility model structure is ingenious, easy to use, and installation site can flexible, all adopts dismountable connected mode between each several part, dismounting is flexible, workable, is convenient to store and carry, and it is little to take up room, and does not need large-area power-cuts during use, reduce loss electricity; Simultaneously low, the small investment of the utility model cost, easy to utilize.

The operation of use the utility model and crane operation are compared, by onsite application, use crane operation to change a switch and need time 3h, after using device of the present utility model, changing a switch needs the time to be 2h, and power failure range is had a power failure by original full station or one section of bus has a power failure changes wall scroll outlet power failure operation into.Calculate according to a 10kV switch institute on-load 1000kW, during crane operation, have a power failure and need 3h, stop 4 circuits, use the utility model is 2h, stop 1 circuit, save time 1h, then losing electricity is less (3 × 4-2 × 1) × 1000kW=10000kWh, by annual maintenance 3 switch statistics, then lose electricity 10000 × 3=30000kWh less, as can be seen here, benefit is considerable.

Embodiment

As depicted in figs. 1 and 2, the utility model is primarily of part compositions such as standpipe 1, swing bar 5 and manual hoist structures 3.

Standpipe 1 is columned body, has transverse arm 2 at the upper weld of standpipe 1, for being fixed on the supporting framework of transformer station, makes standpipe 1 keep hanging state; Transverse arm 2 is perpendicular to standpipe 1 and be divided equally into left and right two parts by standpipe 1, the top of standpipe 1 protrudes from the upper surface of transverse arm 2, weld the deep floor 6 of a ring shape with the junction of standpipe 1 at transverse arm 2, transverse arm 2 is welded on deep floor 6, is fixedly connected with intensity to improve.

Swing bar 5 is tubular body, is inclined at the upper end of standpipe 1, in order to change the horizontal level of lifting object.One section of insertion pipe 4(Fig. 2 is welded in the lower port of swing bar 5), insertion pipe 4 is plugged in the upper port of standpipe 1, and can rotate in standpipe 1.During use, moderate lubrication oil can be smeared on the periphery of insertion pipe 4, be convenient to the rotation of swing bar 5 around standpipe 1.Also be welded with the deep floor 6 of ring shape at insertion pipe 4 and the junction of swing bar 5, form the block plate after insertion pipe 4 grafting.

Also insertion pipe 4 can be made socket pipe, namely its internal diameter is slightly larger than the external diameter of standpipe 1, with the outer surface making it be socketed in standpipe 1.

Weld a pulley 8 in the upper port of swing bar 5 by otic placode, the race of pulley aims at the upper port of swing bar 5.

The bottom of standpipe 1 is provided with manual hoist structure 3.Manual hoist structure 3 is socketed with steel wire rope on reel, turning handle is had in reel arranged outside, after steel wire penetrating standpipe 1, insertion pipe 4 and swing bar 5, stretch out from the upper port of swing bar 5, and under hanging after pulley 8, a suspension hook 7 is connected, to lift by crane the switchgear, current transformer, voltage transformer etc. that use in transformer station in bottom.
