Abstract
The utility model discloses a large-scale nut hoisting device, which comprises a support plate (3) which is horizontally arranged, a pair of cylindrical rollers (2) which is fixed by an axis and rotates around the axis is arranged in the middle part of an upper surface of the support plate (3), hanging rings (5) are respectively arranged on four corners outside the upper surface of the support plate (3), a manual pulling hoist (4) is respectively arranged on two longitudinal sides of each cylindrical roller (2), and each manual pulling hoist (4) is respectively connected with the two hanging rings (5) on the same side through ropes. By the adoption of the hoisting device, the requirement on the large-scale nut from lifting to installation is mainly satisfied, technical problems of a complex process and low efficiency during lifting and installation are solved, and the hoisting device can be applied in the lifting and installation in a horizontal direction of the large-scale nut. During the fastening process of the nut, the horizontal direction of the nut and a screw bolt can be constantly adjusted, and the three-dimensional operation is projected to be carried out on a plane, so that the efficiency of installation is greatly improved, and a damage rate of a screw thread during installing the nut is reduced.
Description
Technical field
The present invention relates to a kind of hanging device, more particularly, relate to a kind of device for the large-scale nut installation.
Background technology
Large-scale nut such as the prop shaft hydraulic efficiency nut of large vessel, generally about 1 ton, and adopts circular design mostly, so handling process more complicated.Owing to needing horizontal direction to install, after putting in place, lifting need rotating nut that it is in place, and in rotary course, need the level of timely adjusting nut to guarantee that the process that tightens realizes smoothly.The tradition lifting device can't make it be in place smoothly.
Summary of the invention
For the problems referred to above, the invention provides the large-scale nut hanging apparatus, be mainly and satisfy large-scale nut from handling to the needs of installing, solve handling installation process complexity, inefficient technical matters, the handling and the horizontal direction that can be applicable to large-scale nut are installed.
In order to achieve the above object, the invention provides a kind of large-scale nut hanging apparatus, the supporting plate that comprises a horizontal, the upper surface middle part of described supporting plate also is equipped with the cylindrical roller that a pair of axis is fixed, rotated around axis, four angles, the upper surface outside of described supporting plate are respectively arranged with suspension ring, the vertical both sides of described cylindrical roller arrange respectively a chain block, and each described chain block connects respectively two described suspension ring of homonymy by rope.Under the optimal way, the outside of cylindrical roller covers one deck soft alloy.
The process of nut tightening is the key that affects efficient, the present invention has had obvious breakthrough in this respect, the horizontal direction of adjusting nut and double-screw bolt constantly in the process of nut tightening, three-dimensional operation projection is carried out in the plane, therefore, significantly improve the efficient of installing, reduced the damage rate of mounting nuts screw thread.
Description of drawings
Fig. 1 is the principle schematic of large-scale nut hanging apparatus of the present invention;
Fig. 2 is the use view of large-scale nut hanging apparatus of the present invention.
The specific embodiment
Large-scale nut hanging apparatus of the present invention as shown in Figure 1 arranges the cylindrical roller 2 of two symmetries on the horizontal supporting plate 3 of width and moderate length.Cylindrical roller 2 is used for holding nut 1, and can freely rotate on horizontal supporting plate 3.Be surrounded by copper coin on the cylindrical roller 2, nut can freely rotate on circle roller.
During use, as shown in Figure 2, four jiaos of horizontal supporting plate 3 arrange respectively suspension ring 5, and nut 1 is placed horizontally on the cylindrical roller 2.After lifting nut 1 puts in place, utilize the level of 4 jiaos of suspension ring adjusting nuts, nut rotates at cylindrical roller 2 and is in place.
Under the optimal way, cylindrical roller 2 two ends are fixed on supporting plate 3 by two antifriction-bearing boxs, cover one deck soft alloy on the cylindrical roller 2, shield.In use, at first with large-scale nut level lifting to device, be placed on moderate position between two cylindrical rollers 2, dull and stereotyped four jiaos sizeable suspension ring are installed, prepare two chain blocks 4, respectively 4 jiaos suspension ring are coupled together.The other end of chain block is as on the same suspension centre; Then large-scale nut is together sling together with this device.After lifting puts in place, utilize the height of dull and stereotyped 4 jiaos of two chain block adjustment to adjust the level of large-scale nut.After adjusting to the right place fully, the rotation large-scale nut tightens it in cylindrical roller 2 rotations, can utilize in this course chain block to come the position of adjusting nut, reaches conveniently installation process.
The above; only be the better specific embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or change according to technical scheme of the present invention and inventive concept thereof, all should be encompassed within protection scope of the present invention.
Claims (2)
1. large-scale nut hanging apparatus, it is characterized in that, the supporting plate (3) that comprises a horizontal, the upper surface middle part of described supporting plate (3) also is equipped with the cylindrical roller (2) that a pair of axis is fixed, rotated around axis, four angles, the upper surface outside of described supporting plate (3) are respectively arranged with suspension ring (5), described cylindrical roller (2) vertically arranges respectively a chain block (4) in both sides, and each described chain block (4) connects respectively two described suspension ring (5) of homonymy by rope.
2. described large-scale nut hanging apparatus according to claim 1 is characterized in that, the outside of described cylindrical roller (2) covers one deck soft alloy.
