Description

Overrun steel structure net rack lifting reverse diagonal pulling device
Technical Field
The utility model relates to an ultralimit steel structure rack promotes technical field, in particular to ultralimit steel structure rack promotes reverse draw device to one side.
Background
The net frame is an article with a stress function in the building industry, is similar to a beam in a house and is usually a steel structure net frame. The lifting columns are columns for assisting the lifting of the rack when the rack is lifted, and are generally steel-structure lifting columns. At any time, the development is being towards the large-span, and the span exceeds 60 m's rack more and more, and when the large-span transfinites steel construction rack and lifts, because the steel construction dead weight is great, require when leading to lifting to the lifting column higher, can produce irreversible plastic deformation even, lead to the engineering failure. In order to ensure the safety of construction and engineering, measures such as additional lifting frames, increased lifting points, increased lifting column size and strength need to be taken. These measures can greatly increase construction costs.
Disclosure of Invention
In order to solve the technical problem, the utility model provides an overrun steel structure rack promotes reverse oblique pull device can realize economic, high-efficient, safe rack promotion.
The utility model discloses a transfinite steel structure net rack promotes reverse oblique-pulling device, including hoisting frame, rope and balancing weight, the hoisting frame is located the top of lifting column, the balancing weight is fixed in ground, sets for the distance with the lifting column bottom, the upper portion of hoisting frame is connected to the one end of rope, and the balancing weight is connected to the other end; the upper portion of hoisting frame sets up the connecting plate, set up the connecting hole on the connecting plate, snap ring one end passes the connecting hole, and wire rope is connected to the other end.
Compared with the prior art, the utility model discloses an advantage is with positive effect: the utility model discloses in order to strengthen the steel construction and promote the post, the steel wire rope is drawn to one side in the hoisting frame installation for the horizontal direction power that produces when balanced transfinite steel structure rack promotes reaches control and promotes post column cap displacement, reduces and promotes post load atress. The utility model has the advantages of realize reducing the structure post reinforcing bar, concrete use amount, realize ensureing that steel construction rack promotes safety, reach economy, simple and convenient, efficient purpose.

Detailed Description
The technical solution of the present invention will be described in further detail with reference to the following embodiments.
The reverse device that draws to one side of transfinite steel structure rack promotion in this embodiment, including hoisting frame 1, rope 3, balancing weight 4, the hoisting frame is located the top of lifting column 6, balancing weight 4 is fixed in ground, sets for certain distance with lifting column 6 bottom, the upper portion of hoisting frame 1 is connected to the one end of rope 3, and the balancing weight, preferred wire rope are connected to the other end. By adjusting the distance between the counterweight 4 and the lifting column, the included angle alpha between the inclination of the rope and the bottom surface is 20-70 degrees, which depends on the mass of the column top lifting frame 1.
The upper beam tail of hoisting frame 1 sets up connecting plate 4 the approximate center of connecting plate 4 puts and sets up connecting hole 5, 2 one end of snap ring is passed connecting hole 5, and wire rope 3 is connected to the other end for wire rope and connecting plate fixed connection, wire rope can utilize the connection effect of snap ring 2 to use the connecting hole as centre of a circle free rotation, and the size of connecting hole 5 and the thickness looks adaptation of snap ring 2 are irrelevant with wire rope's thickness moreover, consequently can change wire rope at will. For example, the diameter of the connecting hole is 50mm, and the diameter of the snap ring is slightly smaller than 50 mm.
The connecting plate 4 is in a combination of an arc surface and a rectangular surface, wherein the arc surface faces the steel wire rope 3, and the friction resistance of the steel wire rope 3 when the steel wire rope rotates freely by taking the connecting hole as a circle center is reduced; wherein the rectangular face is fixedly connected with the column top lifting frame 1, preferably welded. For a connecting plate 4 of 20mm thickness, the minimum weld fillet size between the connecting plate and the hoisting frame 1 is set to 12 mm.
The distance between the top end of the connecting plate 4 and the top end of the column top lifting frame 1 is L1, the distance between the bottom end of the connecting plate 4 and the top end of the connecting plate 4 is L2 (namely the length of the rectangular surface of the connecting plate 4), in order to ensure the same stress, L2 is the same as L1, preferably, L1 is 200mm, and the width of the rectangular surface of the connecting plate 4 is 100 mm.
Through set up the reverse structure of drawing to one side on the hoisting frame at the lift post, horizontal force, the shear force to the support (the junction that indicates lift post and hoisting frame, the place of atress) when balanced steel mesh frame is promoted reduce the capital atress, shorten capital displacement, guarantee to promote the post and be in elastic deformation, can optimize lift post structural dimension and concrete strength problem. The size and the strength of the lifting column are optimized, and economy, safety and high efficiency are achieved. The utility model discloses avoid using additional hoisting frame, increase and promote hoisting point or other measures, do not have additional high altitude construction, can practice thrift the cost, shorten construction cycle, reduce intensity of labour, guarantee construction safety.
The above embodiments are only some of several preferred embodiments of the present invention, and it should be noted that the present invention is not limited to the above embodiments; for a person skilled in the art, modifications may be made to the technical solutions described in the foregoing embodiments, or equivalents may be substituted for some of the technical features; such modifications and substitutions do not depart from the spirit and scope of the present invention, which is claimed.
