Abstract
The utility model discloses a small electrical lifting device which comprises a chassis truck part and a lifting part, wherein the chassis truck part comprises a chassis and wheels; and the lifting part comprises a lifting arm and a ring arranged at front end of the lifting arm. A heavy object within a small range is lifted by a small chassis truck and a foldable lifting arm, so that a volume and an operation radius can be reduced effectively, and the electrified lifting device has small influence on adjacent electrical equipment. An embedded foldable hydraulic disc support leg arranged on the chassis can increase the contact area between the lifting truck and the ground and increase and the dead weight of the truck when in use and retract back to the chassis when not in use, without space occupation; moreover, the foldable lifting arm occupies small space and has large bearing capacity.
Description
Technical field
The utility model belongs to electric power lifting erecting equipment technical field, is specifically related to a kind of small-sized electric power hoisting device.
Background technology
Lifting appliance often uses crane in power station enlarging or the improvement project, common crane volume is big, use the swing and the lifting of its crane arm to be subjected to on-the-spot geographic position and the restriction of charging equipment on every side in the charging equipment district, use very inconvenient, exist safety because of suffering from, sometimes have to enlarge the power failure scope to satisfy usage condition, when for example changing the outdoor current transformer of 110KV, general current transformer is positioned at the back of switch, transformer will could be lifted by crane through switch in crane station on the way crane arm, the raising height of crane arm is subjected to the top to cross the influence of line, and pendulum angle is subjected to the restriction of switch; When changing 110KV bus PT for another example, its installation site or crane can't reach, and perhaps sling height is subjected to the influence of the charged bus in top; Analogue is a lot, in work such as 110KV first (side) disconnecting link, 35KV outdoor switch, 110KV circuit PT outside replacing or the installation room, all has the situation that enlarges the power failure scope because weight-lifting equipment is subjected to the field condition restriction, even can not use weight-lifting equipment.There is not enough, the inconvenient problem of bigger transportation of conducting oneself with dignity of rising height again in common fork truck.These are operated in substation equipment maintenance and repair or install that in the extension project right and wrong are usually seen.Similar little heavy-duty hoisting equipment is arranged both at home and abroad, and as " mechanical spider " that Japan produces, volume is little, and maximum lifting weight, operating radius, sling height all can meet the demands.But one costs an arm and a leg, and two what adopt also is lifting method for it, uses sling height seriously limited in live zone.Other products also are to adopt lifting method, and volume is bigger, do not satisfy the on-the-spot use of substation.The on-the-spot small-sized electric power hoisting device of our power transformation engineering preparing to develop is still blank out in the market at home and abroad so far.
The utility model content
The utility model provide a kind of volume little, flexible and convenient to use, to the less small-sized electric power hoisting device of charged body influence around the sky.
A kind of small-sized electric power hoisting device, it comprises chassis partial sum lifting part, and described chassis partly comprises chassis and wheel, and described lifting partly comprises crane arm and is arranged on the annulus of crane arm front end.
Embedded folding type hydraulic disk supporting leg is set on the described chassis.
Described crane arm is collapsible crane arm.
The annulus of described crane arm front end is the opening and closing type annulus.
The inboard of described annulus is provided with the flexible buffer compliant mechanism.
A plurality of suspension hooks are set on the excircle of described annulus.
Because the lifting of weight in the utility model is realized among a small circle with small-sized chassis and collapsible crane arm, volume and operating radius can reduce effectively, and be little to contiguous on every side charging equipment influence; Embedded folding type hydraulic disk supporting leg is set on the chassis, and the time spent increases crane-car area of contact over the ground, increases the dolly deadweight, in the time spent regracting chassis, does not take up space; Crane arm is collapsible crane arm, and it is little to take up room, and load-carrying capacity is big.The upper arm front end of hoisting device need design an opening and can the osed top annulus, conveniently pick and place weight, circle ring inner wall can the lining batten or flexible buffer compliant mechanism such as rubber pad, can guarantee that weight effectively avoids the collision with annulus in operation process, this annulus can also play the effect that prevents the device inclined overturning.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
A kind of small-sized electric power hoisting device, it comprises chassis partial sum lifting part, and described chassis partly comprises chassis 1 and wheel 2, and described lifting partly comprises crane arm 4 and is arranged on the annulus 5 of crane arm 4 front ends.The lifting of weight in this crane-car can be realized among a small circle, volume and operating radius can reduce effectively, and be little to contiguous on every side charging equipment influence
Embedded folding type hydraulic disk supporting leg 3 is set on the described chassis 1, and the time spent increases crane-car area of contact over the ground, increases the dolly deadweight, in the time spent regracting chassis, does not take up space.Embedded folding type hydraulic disk supporting leg 3 rotates 180 degree during use, shift out in crossbeam, extend to the outside of wheel, the support disk bottom surface of leg ends contacts with ground, by adjustable screw formula vertical lift bar, crawler belt or four wheels of dolly are supported.So not only can effectively increase the load-bearing area of dolly chassis, and can adjust the level of dolly chassis, also increase the deadweight of dolly simultaneously by this adjust bar.Behind the end-of-job, pack up support disk earlier,, be recovered to crossbeam inside by the outside of wheel again with supporting leg Rotate 180 degree.
Described crane arm 4 is collapsible crane arm, and it is little to take up room, and load-carrying capacity is big.The hoisting device of this dolly adopts " Z " font hydraulic pressure or the folding structure of electric up-down.The most significant advantage of this structure is to take up room for a short time, and load-carrying capacity is big." Z " font crane arm is horizontally fixed on the last plane of dolly chassis.
The annulus of described crane arm 4 front ends is an opening and closing type annulus 5, conveniently picks and places weight.
The inboard of described annulus 5 is provided with flexible buffer compliant mechanism 6, can guarantee that weight effectively avoids the collision with annulus in operation process.
A plurality of suspension hooks are set on the excircle of described annulus.
Small-sized electric power hoisting device mainly is made up of two parts,, chassis is 4 to take turns or caterpillar band type, can adopt miniature gasoline engine or fluid motor-driven, F-Zero is no more than 20 kilometers/hour; The folding mode of praising of double-arm hydraulic pressure is partly adopted in lifting.Ground supports area when taking to increase lifting, or the method for designing that counterweight is separated with device alleviates the equipment domestic shipping weight.Hydraulic efficiency equipment and weight-lifting equipment technology maturation, pattern is various, can be used as reference.Difficult point is the mode of praising of miniaturization and use.Annulus becomes rotating structure with the Fixed Design of upper arm front end, guarantees that annulus remains level attitude in each angle of crane arm motion, and the annulus periphery is provided with the suspension hook of suitable quantity as required, uses during with for convenience detach or erecting equipment.
