Abstract
The utility model discloses an anchor chain swivel which comprises a swivel bolt and a connecting box body; a threaded hole is arranged in the connecting box body; and the threaded end of the swivel bolt is inserted into the threaded hole and connected. According to the utility model, the anchor chain switch has the advantages that by the connection of a box body-type connecting structure, gaps at the joint of the swivel bolt are significantly reduced and the gaps at the joint between the connecting box body and the swivel bolt are distributed uniformly, so that underwater sand and other impurities are effectively prevented from entering the connecting box body and being accumulated inside; and in addition, lubricating oil can be injected into the connecting box body, so that the clamping and rusting phenomena of the anchor chain swivel are reduced, the service life is prolonged and the manufacturing is simple.
Description
Technical field
The utility model relates to a kind of swivel, is applicable to the fixing of offshore waters marine engineering works and is connected.
Background technology
Change is the middle shot of anchor chain and being connected and rotatable parts of swivel piece, and its effect not only can transfer torque, and can alleviate because the impact that the effect of wind, wave produces anchor chain.Therefore, it is the indispensable anchor chain accessory that connects and fix facilities such as all kinds of boats and ships, floating drum, landing stage.Along with oil production is progressively moved towards the ocean from land, a large amount of marine engineering works constantly arise at the historic moment, and to the demand of all kinds of mooring gears more and more widely, require also to have nothing in common with each other.
The marine anchor chain change be mainly used in steamer, naval vessels at the harbour, the of short duration captive joint in anchorage, its time used is not long in the whole of life of marine anchor chain service, the most of the time is suspended on fore together with anchor; Therefore; Marine anchor chain change according to above-mentioned working condition requirement manufactures and designs can be satisfied operating needs basically, can be because of not having tens of mm clearance between the ring bolt of change and the body, and cause under water foreign material such as silt to pile up; Cause the ring bolt and the body corrosion of change, rotate ineffective.But, the change of this pattern, if use under water for a long time, silt and foreign material will constantly get between ring bolt and the body, take care of the pence, and finally cause change to change motionless, malfunctioning.The shape and structure of body is special, forges and must adopt die-forging forming and special mould and fixture thereof or production machine processing, and difficulty of processing is big.
The utility model content
The utility model purpose: to the problems referred to above, the purpose of the utility model provides a kind of silt etc. of can preventing and invades the swivel of piling up, and improves its service life.
Technical scheme: a kind of swivel, comprise the ring bolt, also comprise connect box, offer tapped bore on the said connect box, the thread end of said ring bolt inserts said tapped bore and connects.
On the said connect box lubricating cup is set, can prevents that corrosion is ineffective with rotation the lubricating oil of annotating in the connect box.
Said connect box is split type, makes things convenient for set collar bolt and dismounting cleaning.
Beneficial effect: compared with prior art; The utility model has the advantages that the box-type connection structure connects the gap of significantly reducing ring bolt junction, and connect box is even with the junction gap distribution of ring bolt, prevents effectively that under water foreign material such as silt invade accumulation in the connect box; And can be to connect box inside filling lubricating oil; Reduce swivel bite and corrosion phenomena, improve service life, make simple.
Description of drawings
Fig. 1 is the utility model front view;
Fig. 2 is the birds-eye view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment; Further illustrate the utility model; Should understand these embodiment only be used to the utility model is described and be not used in the restriction the utility model scope; After having read the utility model, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the utility model.
Like accompanying drawing 1, shown in 2; A kind of swivel comprises ring bolt 1, connect box 2, and connect box 2 is divided into protruding casing 5 and recessed casing 6; The faying face of protruding casing 5 and recessed casing 6 is offered tapped bore 3; The thread end of ring bolt 1 inserts tapped bore 3, and protruding casing 5 and recessed casing 6 are clipped in the middle it, and is with bolt that protruding casing 5 is fastening with recessed casing 6.Outside lubricating cup 4 is set on the connect box 2, leads to connect box 2 inside.
The processing and manufacturing of connect box 2 is relatively easy, and in general the processing of open die forging and universal machine tools can obtain, and manufacturing cost and production efficiency are occupied clear superiority.
Claims (3)
1. a swivel comprises ring bolt (1), and it is characterized in that: also comprise connect box (2), offer tapped bore (3) on the said connect box (2), the thread end of said ring bolt (1) inserts said tapped bore (3) and connects.
2. a kind of swivel according to claim 1 is characterized in that: lubricating cup (4) is set on the said connect box (2).
