Technical field
The utility model relates to a kind of suspender that lifts usefulness, particularly a kind of special hanger that is used for the lifting fan streamlined reefer housing.
Background technology
In wind power plant, mainly rely on various blower fans to generate electricity.The blower fan quantity of installing in the wind-powered electricity generation factory is many, size is big and heavier, and Installation Flexibility is relatively poor, and installation process and installation period are longer, and it is bigger particularly influenced by wind speed at height, makes the cost of installation height, wastes time and energy.Wherein, all the more so for the installation of blower fan streamlined reefer housing.Blower fan streamlined reefer housing self shape can be handling relatively poor, one end is the semicircle sphere, smooth surface, the other end is a perpendicular end surface, last surface distribution a plurality of tie bolts hole, perpendicular end surface need guarantee vertical angle during connection, and this structure causes the streamlined reefer housing center of gravity to deflect away from laterally, and perpendicular end surface can habituation upwarp; Simultaneously, streamlined reefer housing own wt and volume are bigger, need aloft work during installation, are difficult for seeking equilibrium point aloft, and perpendicular end surface is difficult for alignment, makes that the docking operation of streamlined reefer housing end face and blower fan head is more loaded down with trivial details, has a strong impact on erection schedule.Existing streamlined reefer housing lifting all is to use common suspender, its structure is not considered the particularity of lifting streamlined reefer housing, provides convenience for the later stage installation of streamlined reefer housing, and installation process can only rely on workman's field engineering, installation effectiveness can't be improved, and cost of installation can't reduce.How provide convenience, improve workman's installation effectiveness, simplify installation process, want the problem that solves with regard to becoming the utility model for installation process.
Summary of the invention
In view of above-mentioned existing situation, the utility model aims to provide a kind of and the matching used special hanger of blower fan streamlined reefer housing, and with the lifting alerting ability and the lifting balance that improve streamlined reefer housing, it is more convenient, safer, faster that streamlined reefer housing is installed.
The utility model is achieved through the following technical solutions:
A kind of suspender, comprise lifting part, can realize that horizontal direction holds hold balance block of partial sum, the lifting partial fixing is holding on the part, balance block is fixed on and holds part one end.
Described holding section branch comprises the activity catching more than three or three, and described activity catching one end is provided with dop, and the other end evenly is hinged on the balance block.
Described dop is a fixture block that is hinged with the activity catching, and fixture block is provided with tapped bore.
Described lifting part comprises suspension hook and a gravity centre adjustment mechanism, and suspension hook is connected on the gravity centre adjustment mechanism, and gravity centre adjustment mechanism is grabbed the body middle part near what be connected the activity catching.
Described gravity centre adjustment mechanism comprises screw rod, coupling bush and two setscrew nuts, screw rod is fixed near on the position of grabbing the body middle part along the vertical equity of activity catching, setscrew nut is connected on the screw rod, suspension hook is fixed on the coupling bush, be communicated with jacket casing on screw rod, setscrew nut is positioned at the coupling bush two ends.
A kind of suspender described in the utility model, adopt three or three above activity catchings and turning fixture block to be connected with streamlined reefer housing, utilize balance block and the lifting part that has gravity centre adjustment mechanism that hoisting process is carried out Balance Treatment, make streamlined reefer housing when lifting, can keep good use attitude, for the installation process after slinging is provided convenience, reduce installation difficulty, simplified installation process, improved installation effectiveness.Utilize gravity centre adjustment mechanism to realize the adjustment of suspension hook position, the accuracy of balance control when having guaranteed to sling.Utilize three open different angles of activity catching, satisfy the lifting needs of different size streamlined reefer housing, enlarged Applicable scope.Have simple in structurely, practical, easy to use, flexible, highly versatile, durable advantage can shorten set-up time of streamlined reefer housing greatly, and its structure is highly suitable for wind power plant and promotes the use of.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of hoisting process.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, a kind of suspender described in the utility model, comprise lifting part, can realize that vertical direction holds hold balance block 9 of partial sum.The holding section branch comprises three activity catchings 1, and activity catching 1 outer end is provided with dop, and dop is a fixture block 2 that is hinged with activity catching 1, and fixture block 2 is provided with tapped bore 3, and tapped bore 3 can be connected with the tapped bore on the blower fan streamlined reefer housing end face.The inner of activity catching 1 evenly is hinged on the balance block 9 by hinge 8, and balance block 9 is a metal blocks, mainly plays the effect of carrying out balance with streamlined reefer housing, guarantees that streamlined reefer housing can be lifted by level.Pivotally attached activity catching 1 can be overturn with respect to balance block 9, to be fit to the streamlined reefer housing of different-diameter.Three activity catchings 1 have kept connection stability, have also improved the bonded assembly alerting ability simultaneously.Certainly, also can hinged more a plurality of activity catchings 1 on balance block 9 as required, to adapt to the use needs of different streamlined reefer housings liftings.
The lifting part comprises suspension hook 7 and a gravity centre adjustment mechanism.Gravity centre adjustment mechanism mainly plays on the basis that balance block 9 effects are arranged, and further finely tunes the balance center of gravity of whole suspender, guarantees smooth, the level lifting of streamlined reefer housing.Gravity centre adjustment mechanism comprises screw rod 4, coupling bush 5 and two setscrew nuts 6.Screw rod 4 is fixed near on the position of grabbing the body middle part along the vertical equity of activity catching 1, and setscrew nut 6 is connected on the screw rod 4.Coupling bush 5 is enclosed within on the screw rod 4, and suspension hook 7 is fixed on the coupling bush 5, and setscrew nut 6 is positioned at coupling bush 5 two ends.Suspension hook 7 by coupling bush 5 can be on screw rod 4 parallel motion, guaranteed the skew adjustment of center of gravity.
As shown in Figure 2, in the working process, streamlined reefer housing 10 horizontal card are held in the activity catching 1, the fixture block 2 upset backs on activity catching 1 top are connected in the tapped bore of streamlined reefer housing 10 end faces by screw, and streamlined reefer housing 10 is captiveed joint with activity catching 1.Because streamlined reefer housing 10 semicircle spheries one amount of stressing is heavier, streamlined reefer housing 10 centers of gravity can be to activity catching 1 inboard inclination.Adjust the position of coupling bush 5 on horizontal screw bolt 4, the level attitude of control suspension hook 7, and utilize setscrew nut 6 with coupling bush 5 stationkeeping, the effect of binding equilibrium piece 9, adjusted suspension hook 7 is on the equilibrium point of integral structure center of gravity, and the streamlined reefer housing of slinging 10 can remain horizontality, like this, the perpendicular end surface that is positioned at streamlined reefer housing 10 1 sides then can remain plumbness, for the high-altitude installation exercise provides convenience.When the streamlined reefer housing 10 of lifting different size, can the position of corresponding adjustment coupling bush 5 on screw rod 4, suspension hook 7 is positioned on the position of structural focus all the time, positioning of rotating nut 6 with coupling bush 5 location after, can finish once more the level lifting.
