Detailed Description
The following describes the present design in detail with reference to the accompanying drawings.
As shown in fig. 1-2, a triangular lifting lug 3 for hoisting large-scale equipment structurally comprises a support frame 1, a back plate 2, lifting lugs 3 and tail support seats 4, wherein the support frame 1 is a triangular structure formed by welding three H-shaped steels and used for supporting the whole under stress, the back plate 2 is arc-shaped and is fixedly connected to the top of the front end of the support frame 1, the number of the tail support seats 4 is two, the two tail support seats are respectively and fixedly connected to the intersection of the support frame 1 at the tail end of the support frame 1, the outer edge of each tail support seat 4 is arc-shaped, and the diameter of each tail support seat is the same as that of the outer edge of the back plate 2. The outer fringe of afterbody supporting seat 4 and the outer fringe equipartition of backplate 2 are equipped with opening 6 of certain quantity, wherein backplate 2 matches each other with the outer diameter of the equipment bottom of hoist and mount with the outer diameter of the outer fringe diameter of afterbody supporting seat 4, opening 6 be used for with hoist and mount between the equipment link to each other with the bolt, 3 fixed connection in the front end of support frame 1 of lug, two atress boards 5 of top surface of backplate 2 still fixedly connected with, the convex cardboard 7 of top surface still fixedly connected with of every afterbody supporting seat 4, atress board 5 is unanimous with the equipment bottom hole shape and size of hoist, for the fixed atress, the outer fringe of cardboard 7 closely laminates with the inboard circular arc of equipment bottom apron seat, with this effect that reaches the support stress.
Examples
The specification and model of the hoisting equipment are as follows: phi 4500X20915.6mm, the weight of the equipment is: 260t, the specific gravity of tail slipping equipment is as follows: 88.528t are examples.
(1) Manufacturing a support frame 1:
three H-shaped steels (HW400 x 15Q235B) are connected end to end and are assembled and welded to form a tripod. This part is the main support part; the concrete practical size is adjusted with the skirt size at the bottom of actual equipment. Since the size of the foundation bed seat referred to this time is R2250 mm, the support frame 1 has the following dimensions: 3841mm, 3841mm and 3785 mm.
(2) Manufacturing a stressed part of the back plate 2:
a steel plate (t ═ 50mm Q235B) is used as the back plate 2, and is attached to the equipment base, and is fixedly connected to the equipment base bolt holes by bolts. And a vertical plate (3498mm x 400mm t: 50mm Q235B) is welded on the outer side of the back plate 2 to be used as a stressed top plate. The middle of the top plate, the outer side of the back plate 2 and the triangular supports are welded with the lifting lugs 3 together.
Two stress plates 5(550 x 300t is 50mm Q235B) are welded on the top surface of the back plate 2, and the stress plates 5 are consistent with the shape and size of the holes of the bottom plate of the equipment and used for fixing the stress.
(3) Manufacturing a tail supporting seat 4:
the bottom ends of the triangular supports on two sides are respectively welded with a tail supporting seat 4(1500mm x 600mm) by adopting a steel plate (t is 50mm Q235B), and the tail supporting seat 4 is attached to the equipment base and fixedly connected with a bolt hole of the equipment base by using a bolt. The top edge of the tail supporting seat 4 is made of a steel plate (t is 50mm Q235B) to form a clamping plate 7, and the edge of the clamping plate 7 is processed by an arc to be tightly attached to the inner side arc of the skirt at the bottom of the equipment, so that the supporting stress effect is achieved.
After the preparation is accomplished, hoist through lug 3, this utility model construction progress has been accelerated, has practiced thrift manual work, mechanical cost to make obtaining of the security of hoist and mount in-process guarantee. Finally, good results are obtained.
