Abstract
The utility model provides a hoisting rack, comprising a fixation seat, a pillar, a cross beam and a hoisting pulley, wherein the pillar is fixed on the fixation seat and a rotary axle is arranged on the upper end of the pillar; the cross beam is fixed on the rotary axle; the hoisting pulley is mounted below the cross beam and flexibly slides on the cross beam; an end plug is arranged at the end of the cross beam; a plurality of long groove holes are arranged on the fixation seat and a plurality of hook head clamping plates are arranged at the bottom of the fixation seat. The hoisting rack has features of simple structure, convenient mounting, safety and reliability and effectively prevents the human and device failure.
Description
Technical field
The utility model relates to a kind of lifting machinery, more particularly relates to a kind of mast-up that is used for lifting by crane on the pantograph out of doors voltage, current transformer.
Background technology
At present, in safeguarding the outdoor lifting operation of voltage, current transformer, when installation or dismounting transformer is to adopt traditional approach basically, promptly hanging pulley on pole lifts by crane, this hoisting method is because the restriction of position, Heave Here, the equipment that hangs can't be placed on the position that will install when winching to the high-altitude, the operator will accurately be placed in desired location with the equipment of kilogram weight more than 100, need overcome very big difficulty, so construction, have a big risk, safety factor is low, the on-the-spot person and the equipment breakdown of taking place easily.
Summary of the invention
The utility model has overcome shortcoming of the prior art, and a kind of mast-up that is used for lifting by crane on the pantograph out of doors equipment such as voltage, current transformer is provided.
The utility model is realized by following concrete scheme: a kind of mast-up, comprise that permanent seat, column, crossbeam have reached Hanging roller, column is fixed on the permanent seat, the upper end of column is provided with rotating shaft, crossbeam is fixed in the rotating shaft, play Hanging roller and be installed in the below of crossbeam, and can slide flexibly on crossbeam, the termination of crossbeam is provided with plug; A plurality of long slot bores are set on the permanent seat, and the bottom surface of permanent seat is provided with a plurality of gib head clamping plate.
A kind of mast-up of the utility model compared with prior art, its beneficial effect is: 1, because crossbeam can rotate around column, play a Hanging roller and can slide flexibly along crossbeam, so can accurately be placed in assigned address by lifting appliance; 2, simple in structure, easy for installation, safe and reliable, can effectively avoid the generation of the person and breakdown of equipment.
Description of drawings
Accompanying drawing is the structural representation of a kind of mast-up of the utility model.
Among the figure: 1. a Hanging roller, 2. crossbeam, 3. digonal link, 4. rotating shaft, 5. bearing carrier ring, 6. bearing, 7. column, 8. permanent seat, 9. gib head clamping plate, 10. fixed mount, 11. bolts, 12. nuts, 13. reinforcing sleeves, 14. plugs.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment a kind of mast-up of the utility model is further described: among the figure, column 7 is fixed on the upper surface of permanent seat 8, reinforcing sleeve 13 is enclosed within on the lower end cylindrical of column 7 and is fixed on the permanent seat 8, the upper end of column 7 is fixed with bearing carrier ring 5, rotating shaft 4 is fixed in the bearing carrier ring 5 by bearing 6, crossbeam 2 is fixed in the rotating shaft 4, play Hanging roller 1 and be installed in the below of crossbeam 2, and can on crossbeam 2, slide flexibly, for having prevented Hanging roller 1 slippage from the crossbeam 2, be provided with plug 14 in the termination of crossbeam 2.In order to reduce the weight of mast-up, and will guarantee that mast-up has enough intensity, crossbeam 2 and column 7 all adopt the light aluminum alloy section bar, simultaneously, are provided with digonal link 3 between the termination of crossbeam 2 and rotating shaft 4.Four long slot bores evenly are set on permanent seat 8, are used for installing and fixing, the bottom surface of permanent seat 8 is provided with four gib head clamping plate 9, all has bolt 11 and nut 12 on each gib head clamping plate 9.
During use, at first permanent seat 8 is fixed on by gib head clamping plate 9, bolt 11 and nut 12 on the channel-section steel 10 on the pantograph of equipment requiring installation, the column 7 that will have crossbeam 2 again is fixed by bolts on the permanent seat 8, fixes reinforcing sleeve 13 simultaneously.Lifting rope has been walked around Hanging roller 1, and an end of lifting rope is tied up on the quilt voltage or current transformer that lift by crane, and the other end that the workman holds lifting rope pulls down, and will be moved on the pantograph that needs to install by lifting appliance.At this moment, rotating beam 2 moves on to equipment on the accurate position that needs to install, and slowly puts lifting rope, equipment is dropped on the pantograph fix.
The utility model mast-up simple structure is light and handy, be convenient to move and install, and independent stationary, easy and simple to handle can effectively avoid the person, equipment breakdown to take place.
