Abstract
The invention discloses a device for horizontally installing a heavy nut, which comprises a lifting lug, a lifting ring, a plurality of bolts, a plurality of ball bodies and a transition lantern ring, wherein the lifting lug is arranged on the lifting ring, the transition lantern ring is arranged in the lifting ring, more than two bolt holes are symmetrically arranged in the outer cylindrical surface of the lifting ring by using a center shaft where the lifting lug is in, the outer surface of the transition lantern ring is provided with an arc groove in the circumference direction, the bolts are arranged in the bolt holes, and the ball bodies are arranged in contact parts of the bolt holes and the arc groove in the transition lantern ring and the lifting ring. The device is used for improving the traditional installing mode so as to increase lifting stability; and the steel balls are arranged on the lifting ring, and sliding friction is changed into rolling friction, thus the labor intensity of workers is lowered, and working efficiency is increased. The invention has the advantages of simple structure, compact size, convenience for maintenance, low cost and reliable property, and is suitable for installing nuts with polygon and round outer edges.
Description
Technical field
The present invention relates to a kind of level the device of heavy nut is installed, relate in particular to a kind of erecting device that replaces sliding friction with rolling friction.
Background technology
At present the shipyard method that level is installed heavy nut aboard ship or on the main equipment is to entangle nut with steel wire rope, and is coaxial through bottle gouard moved by hands hoisting nut and double-screw bolt, rotates nut again it is screwed on the double-screw bolt.This method is because contact area causes the poor stability of nut for a short time, screw in very difficulty and have potential safety hazard, simultaneously again since when screwing in nut the friction between nut and the steel wire rope be sliding friction, working strength of workers is big, shortcomings such as inefficiency.
Summary of the invention
The objective of the invention is to: overcome the above-mentioned defective of conventional art, provide a kind of level of rolling friction mounting means of large tracts of land contact that heavy nut apparatus is installed.
The present invention is made up of hanger, suspension ring, a plurality of bolt, a plurality of spheroid, the transition collar; Hanger is arranged on the suspension ring; The transition collar is arranged in the suspension ring, on the suspension ring external cylindrical surface, have two above screws with hanger place central shaft symmetry, correspondingly has the garden arc groove on the circumferencial direction at the spacer shell ring outer surface; Bolt all is housed in the screw, and in each screw and the contact position of the inherent transition collar of arc groove and suspension ring is provided with spheroid.
The transition collar according to the invention is round outside but spuare inside structure.
Spheroid according to the invention is a steel ball.
The present invention improves traditional mounting means; Former steel wire rope contacted with the nut line change suspension ring into and contact with the face of the transition collar (or round nut); Increase the stability of lifting, simultaneously steel ball is set on suspension ring, sliding friction is become rolling friction; Reduce working strength of workers, increase work efficiency.The present invention is applicable to that outer rim is that polygon and circular nut are installed, and when nut is the polygon outer rim, then directly puts into the transition collar with nut; When nut was circular outer rim, then the arc groove on round nut outer rim car rounding Zhou Fangxiang was directly put into suspension ring (not needing the transition collar under this operating mode) with it.It is simple in structure, and compact dimensions is easy to maintenance, and is with low cost, dependable performance.
Description of drawings
Fig. 1 is a structure principle chart of the present invention;
Fig. 2 is the A-A cutaway view of Fig. 1, and the center of gravity that device is described overlaps with the center of suspension ring and the perpendicularity of device and horizontal plane, has guaranteed the security of lifting.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is elaborated.
The present invention is made up of hanger 1, suspension ring 2, a plurality of bolt 3, a plurality of steel ball 4, the transition collar 5.Hanger 1 is arranged on the suspension ring 2; The transition collar 5 is arranged in the suspension ring 2; Outside suspension ring 2 on the cylinder of garden, have seven screws with hanger 1 place central shaft symmetry, one of them is positioned on the hanger 1 place central shaft, correspondingly has the arc groove on the circumferencial direction at the spacer shell ring outer surface; Bolt all is housed in the screw, and in each screw and the contact position of the inherent transition collar of arc groove and suspension ring is provided with spheroid.
Bolt 3 screws in the screws in order to the supporting steel ball, makes simultaneously that the transition collar (or round nut) is unlikely to skid off from suspension ring 2.So just can nut be sling through hanger 1, it is coaxial with double-screw bolt to adjust nut then, rotates the installation that nut can be accomplished nut again.Concrete method for using is the steel ball of garden arc groove to hold to put on circumferencial direction of outer rim car system of the transition collar; Suspension ring are inserted on the transition collar; The garden arc groove of the transition collar is put into and aimed to steel ball from the screw of the outer cylinder surface of suspension ring, screw in the supporting steel ball with bolt again.The hanger on the suspension ring of utilizing that so just can be very safe is sling this device and very easily nut is screwed on the double-screw bolt.
Claims (3)
1. a level is installed the device of heavy nut; It is characterized in that: be made up of hanger, suspension ring, a plurality of bolt, a plurality of spheroid, the transition collar, hanger is arranged on the suspension ring, and the transition collar is arranged in the suspension ring; On the suspension ring external cylindrical surface, have two above screws with hanger place central shaft symmetry; Correspondingly have the arc groove on the circumferencial direction at the spacer shell ring outer surface, bolt all is housed in the screw, in each screw and the contact position of the inherent transition collar of arc groove and suspension ring is provided with spheroid.
2. level as claimed in claim 1 is installed the device of heavy nut, it is characterized in that: the transition collar is round outside but spuare inside structure.
