Description

Prefabricated part hoist

Technical Field

The utility model relates to a prefabricated component hoist for the prefabricated component of heterotypic hoist and mount hole.

Background

At present, the common prefabricated parts are mostly hoisted by adopting embedded lifting lugs. But there is a prefabricated component, does not set up pre-buried lug, but is equipped with 4 heterotypic hole for hoist in its main part, and this heterotypic hole for hoist upper portion is the cuboid, and the bottom is the cylinder. The construction can not be directly carried out according to the conventional hoisting operation.

Disclosure of Invention

The utility model aims to solve the technical problem that a prefabricated component hoist is provided, the hoist and mount of the above-mentioned prefabricated component of taking abnormal shape hole for hoist is exclusively used in.

In order to solve the technical problem, the utility model discloses the technical scheme who adopts is:

a prefabricated part lifting appliance comprises an inverted T-shaped plate, wherein the inverted T-shaped plate extends into a special-shaped hole, and the horizontal part of the inverted T-shaped plate is limited by a sleevelet at the upper end of the special-shaped hole; the top end of the inverted T-shaped plate is fixed with a rotating shaft, the rotating shaft is rotatably arranged on a bearing locking mechanism, and the bearing locking mechanism is detachably connected with the support.

The bearing locking mechanism comprises a fixed seat which is rotatably connected with the rotating shaft through a bearing; the upper end of the rotating shaft is locked by a nut and a gasket.

And a reinforcing plate is arranged at the transition position of the horizontal part and the vertical part of the inverted T-shaped plate.

The utility model relates to a prefabricated component hoist, through set up on the support with the prefabricated component on the heterotypic hole for hoist of the corresponding quantity of hoist T template, the T template that falls passes through bearing locking mechanism and support rotatable coupling, through the rational design to the T template size that falls for the T template that falls breaks away from in the heterotypic hole for can conveniently hoist fast like this, accomplishes this kind of prefabricated component's the operation of lifting by crane through rotatory unable follow heterotypic hole after stretching into heterotypic hole for hoist. The inverted T-shaped lifting appliance is simple to process, low in cost, economical and applicable.

In the figure: the novel inverted T-shaped plate comprises an inverted T-shaped plate 1, a rotating shaft 2, a bearing locking mechanism 3, a support 4, a round hole 5, a fixed seat 6, a bearing 7, a nut 8, a gasket 9, a reinforcing plate 10, a square sleeve 11, a limiting screw rod 12, a lead screw 13, a lug plate with a hole 14, a prefabricated part 15, a special-shaped hoisting hole 16 and a cuboid groove hole 17.

Detailed Description

As shown in figure 1, the prefabricated part lifting appliance comprises an inverted T-shaped plate 1, wherein the inverted T-shaped plate 1 is a Q235 steel plate, the thickness of the inverted T-shaped plate is 40mm, and the length of the inverted T-shaped plate is 1300 mm. The length here can also be varied according to the actual need. And a reinforcing plate 10 is arranged at the transition position of the horizontal part and the vertical part of the inverted T-shaped plate 1, and the inverted T-shaped plate 1 and the reinforcing plate 10 are fully welded. Reinforcing plate 10 is Q235 steel sheet, and is isosceles triangle, and reinforcing plate 10's thickness is 10mm, because this department is the atress section, strengthens handling in order to guarantee to lift by crane safety this.

As shown in fig. 1 and 3-4, a connecting part is bent at the top end of the inverted T-shaped plate 1, and the connecting part is fixedly connected with the square sleeve 11 above the connecting part through a plurality of bolts. The upper end of the square sleeve 11 is provided with a through hole, the rotating shaft 2 passes through the through hole, and the lower end of the rotating shaft is fixedly connected with the limit screw 12 through threads. The upper end of the rotating shaft 2 is connected with the inner ring of the bearing 7 in an interference fit manner, and the outer ring of the bearing 7 is connected with the counter sink on the fixed seat 6 in an interference fit manner. The top end of the rotating shaft 2 is in threaded connection with a screw rod 13, and the nut 8 and the gasket 9 penetrate through the screw rod 13 and then are locked. The gasket 9 here is great, can with the terminal surface contact of pivot 2 terminal surface, fixing base 6, consequently after the nut 8 of screwing, the unable fixing base 6 of pivot 2 relative rotation, after loosening the nut 8, the relative fixing base 6 of pivot 2 rotates.

As shown in fig. 2, the fixing seats 6 are mounted on the front, rear, left and right corners of the bracket 4 by bolts. Four perforated ear plates 14 are arranged on the bracket 4, and the lifting operation can be carried out by connecting the perforated ear plates 14 with a steel wire rope.

Here, as shown in fig. 2, the special-shaped hoisting hole 16 on the prefabricated part 15 comprises an upper rectangular slotted hole 17 and a lower round hole 5. The length of the horizontal part of the inverted T-shaped plate 1 is larger than the width of the cross section of the cuboid groove hole 17 and smaller than the length of the cross section of the cuboid groove hole 17, and the height of the horizontal part of the inverted T-shaped plate 1 is smaller than the depth of the round hole 5.

The working principle and the process are as follows: before the operation of lifting by crane, at first, loosen nut 8, put into the board 1 of falling T (as shown in A department in figure 5) along the long edge direction of cuboid slotted hole 17, when waiting to touch the hole bottom of round hole 5 completely, the manual work is to the board 1 of falling T rotatory 90, makes the horizontal part of the board 1 of falling T and the long limit of cuboid slotted hole 17 be 90 (as shown in B department in figure 5), lock nut 8, the board 1 of falling T like this limits can' T shift out in heterotypic hoist and mount hole. After all the inverted T-shaped plates 1 are installed in place, the perforated ear plates 14 are provided with standard lifting ring snap rings which are connected with lifting hooks of lifting equipment by using steel wire ropes, and lifting operation is carried out. After the hoisting operation is finished, the nut 8 is loosened, the inverted T-shaped plate 1 is rotated by 90 degrees, the long edge of the horizontal part of the inverted T-shaped plate 1 corresponds to the long edge of the cuboid slotted hole 17, and then the inverted T-shaped plate is taken out.
