The purpose of this utility model is to propose further improvement, flexible connecting device peculiar to vessel after the improvement, below the position of former automatic lock pincers, increase a fork type clamp device that plays clamping action, this strengthening part can guarantee to make above-below direction free lifting between the head and the tail that connect hull, be subjected to effectively spacing on the left and right directions, the force-bearing situation of coupling member overcomes the safety hazard that is brought by stress concentration when improving operation, improves the work life and the reliability of connecting device.

The flexible connecting device peculiar to vessel that the utility model provides, comprise the intermediate connector of a band master cylinder that is located on the push boat and the automatic lock pincers that is divided into push boat front end both sides, with be arranged on the top and refute the post that pushes away of the intermediate connector joint chute of tail end and both sides, it is corresponding to push away post and automatic lock pincers, it is characterized in that below automatic lock pincers on the push boat, being set with on the certain distance and with push away the cooresponding fork type clamp device of post.

Described fork type clamp device, its shift fork mount pad is embedded in the push boat antetheca, and seat is provided with the shift fork piece of a trough of belt mouth in the shift fork mount pad.

Two medial surfaces of described shift fork mount pad are provided with the cushion rubber that damping is used.

The inboard of described shift fork piece is provided with the anti-attrition piece that anti-attrition is used.

Good effect of the present utility model is: 1, owing to increased the clamp device of spacing usefulness, point of attachment, top fulcrum between the hull head and the tail become five points from three original points, the huge moment that produces when wherein the arm of force that forms between two origin of force of Zeng Jiaing is used for reducing the hull labor, guarantee safe operation, make hull maintain the pulsation-free state as far as possible.2, owing to shipborne cooresponding two origin of force of post that push away, two position of the fulcrum distances of promptly cooresponding automatic lock pincers and shift fork piece are bigger, so strained condition can design more rationally on the framing member of connecting device.Moment is constant, but the arm of force is long, and stressed just little, stress is corresponding to be reduced, thereby has improved the work life and the reliability of framing member.

3, this device has increased by two fork type clamp devices on the basis of original structure, and simple and reasonable, volume is less, so cost reduces; And make easy for installationly, and operation is convenient, and effect is apparent in view.

Be described further below in conjunction with embodiment and accompanying drawing thereof.

Fig. 1 is the prior art constructions scheme drawing.

Fig. 2 is a structural representation of the present utility model.

Fig. 3 is the example structure figure of fork type clamp device.

Fig. 4 is shift fork block part figure.

Referring to accompanying drawing.As shown in Figure 1, the utility model is the improvement of doing on the prior art basis, the basic composition of this flexible connecting device peculiar to vessel comprises two automatic lock pincers 3 on an intermediate connector 5, both sides, push boat 4 clamps 3 obvolvents by automatic lock and pushes away post 2 and pushing tow top refute 1 forward, on the push boat automatic lock clamp 3 belows be respectively equipped with one with the corresponding fork type clamp device of two thruster posts.This intermediate connector 5 adopts the controlled flexible mechanism of fluid pressure types, and it has and connects and the double action of ejection, and its head construction is common T font joint and ball-joint joint, and push rod can stretch and rotate.The automatic lock on both sides pincers 3 are with to push away post 2 corresponding, and the phase obvolvent, are that activity connects, and hold firmly the pusher post and can center on the action radius that jaw circumferentially have the 3-5 degree.Simultaneously, pushing away post can be up and down in jaw with hull, free lifting.The regimen in inland river changes not quite generally speaking, and the gap that its obvolvent position is stayed can guarantee to connect the action radius that the 3-5 degree is arranged between ship relatively, just can satisfy operating needs.Automatic lock shown in Figure 1 pincers about 3 are respectively established one, and each fulcrum of framing member of connecting device stressed is in very abominable situation, when waving when going beyond the limit the final result that all will cause the automatic lock pincers to damage between hull.Traditional compensation way is to adopt the increasing scantling of structure to guarantee its safeguard construction performance.

Shown in Figure 2, structural development of the present utility model is: it is below automatic lock pincers 3, and this example is provided with a fork type clamp device (about each, generally be no less than two) under being, it and push away the post corresponding matching, push away post and be positioned among the jaw obvolvent.During normal operation, the fore-and-aft direction angle changes not quite between the connection ship, so can not push away the phenomenon that post breaks away from jaw, pushes away the moving range of post in jaw and can guarantee that (design) is in 5 of typing is spent.In fleet's navigation, push away post and have 20 centimetres approximately with respect to the lifting elevation change that automatic lock clamps, high 2 meters to be permitted be one in a small amount with respect to ship side, distance between automatic lock pincers and the fork type clamp device fulcrum is provided with easily on request, and the arm of force of choosing between stressed fulcrum is long more, and moment is constant, the fulcrum place is stressed just more little, stressed little, stress is also little, just can not cause the framing member of connecting device to damage.On the other hand, just do like this and might come cost-cutting with the approach that reduces the framing member size.

Its mode of operation is summarized as follows:

First kind of situation: when the push boat of back is refuted into the forward pushing tow with the fwd top, just in time be equivalent to two hulls and be the rigid attachment situation.The automatic lock on both sides clamps and pushes away in the obvolvent of post clamper stressed, contracts in the push rod of intermediate connector, is not subjected to vertically to connect power, only relies on the automatic lock pincers to head on and refutes navigation forward.In the navigation, the post that pushes away of hull point of attachment can free lifting with hull; The moment that labor produced between hull then acts on two fulcrums up and down that push away post, and the gap of automatic lock pincers place's obvolvent is less, below action radius big (3-5 degree) in the clamp device, make hull remain on plateau, promoting fleet and moving ahead;

Second kind of situation: when running into the inland river bend, will regulate certain angle between refute on push boat and top could navigate by water and pass through, keep automatic lock pincers on one side to push away the obvolvent of post clamper with cooresponding, another side is thrown off, intermediate connector stretches out push rod forward and is a top strained condition, regulate the length of intermediate connector push rod, guarantee the angle that two ships are flexed into to be needed, fleet is normally navigated by water along tortuous channel.But push away post with ship above-below direction free lifting still on the hull, the moment that labor produces on the left and right directions also act on its on one side push away the automatic lock pincers on the post and the fulcrum place of fork type clamp device, action effect is identical.

Fig. 3 has represented the installation and the version of fork type clamp device in detail.4 expression push boats wherein, shift fork mount pad 11 is located on the push boat antetheca, is embedded with the cushion rubber 16 that damping is used on its two sides, in the middle of the shift fork piece 12 of trough of belt mouth 14 is installed.2 are the post that pushes away under the mode of operation.The stage clip 8 of buffering usefulness is housed on the joint column cap of shift fork piece 12, is installed on then on the annular bearings 10 that is welded on the shift fork mount pad.The 9th, the end cap case that capping is used.The medial surface of notch 14 is provided with the anti-attrition piece 13 that anti-attrition is used.Seat accent both sides at shift fork mount pad 11 respectively are provided with baffle plate 15, block shift fork piece 12, do not allow it outwards deviate from.

Shift fork block part shown in Figure 4, its columniform joint column cap are used for equipped buffering with stage clip 8 and annular bearings 10, push away post and shift fork piece movable effect that connects in the shift fork mount pad in the hope of reaching.

As mentioned above, technical scheme has proposed under the principle prerequisite that guarantees the lifting of hull easy on and off, in the flexible movable connecting device of employing, and adds clamp device and carries out after greater than 5 degree effectively spacing to the hull labor.The quantity of this clamp device, similar structures form and relative position can change to some extent, and in addition, even the installation site that its framing member is refuted on push boat and top also can exchange.These variations all are to belong to equivalents of the present utility model.
