Abstract
The utility model discloses a device for horizontally installing a heavy nut, which is formed by a lifting lug, a lifting ring, a plurality of bolts, a plurality of balls and a transition lantern ring. The lifting lug is arranged on the lifting ring, and the transition lantern ring is arranged in the lifting ring. More than two screw holes are arranged on the outer cylindrical surface of the lifting ring symmetrical to the central axis where the lifting lug locates. Correspondingly, arc-shaped grooves are arranged on the outer surface of the transition lantern ring along the circumferential direction. The insides of the screw holes are all provided with the bolts. Balls are arranged on the contact positions of the transition lantern ring and the lifting ring in each screw hole and each arc-shaped groove. The device for horizontally installing the heavy nut improves the traditional installing mode and stability of lifting arrangement. Simultaneously, steel balls are arranged on the lifting ring, thereby changing sliding friction mode into a rolling friction mode, reducing work strength of workers and improving work efficiency. The device for horizontally installing the heavy nut is simple in structure, compact in size, convenient to maintain, low in cost, reliable in performance and suitable for the installation of nuts with polygonal and circular edges.
Description
Technical field
The utility model relates to the device that a kind of level is installed heavy nut, relates 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 by 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, screws in very difficult and has potential safety hazard, simultaneously again since when the screw-in nut 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 purpose of this utility model is: 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 utility model is made 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 have 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 described in the utility model is round outside but spuare inside structure.
Spheroid described in the utility model is a steel ball.
The utility model 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, steel ball is set on suspension ring simultaneously, sliding friction is become rolling friction, reduce working strength of workers, increase work efficiency.The utility model 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 utility model;
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 utility model is elaborated.
The utility model is made 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 have 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 by hanger 1, it is coaxial with double-screw bolt to adjust nut then, rotates the installation that nut can be finished nut again.Concrete using method 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: constitute by 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 have 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 garden 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.
