Summary of the invention
The technical problem to be solved in the present invention provides a kind of hanging device and suspension hook structure thereof, can offset and reduce to jolt and the deep-sea operating mode under the goods situation of jolting, improved stability and safety, and can reduce the cold punching requirement.
For solving the problems of the technologies described above, the invention provides a kind of suspension hook structure, comprising:
Suspension hook;
The body skin of captiveing joint with described suspension hook;
Be fixedly connected on the suspension rod on the flap seat;
Be fixedly connected on the lower nut on the described suspension rod;
Be arranged at the recoil spring group between described body skin and the lower nut;
Wherein, described suspension hook lifts by crane and spurs described body skin and then push described recoil spring group when stressed, described recoil spring group by described lower nut with stressed described suspension rod and the flap seat of being passed to.
Alternatively, being shaped as of described body skin is cylindric, and bottom surface has mounting hole on it, and described suspension rod penetrates in the described mounting hole and with described body skin to become to flexibly connect.
Alternatively, described suspension hook structure also comprises: be arranged at the erosion control spring assembly between described body skin and the flap seat.
Alternatively, described suspension hook structure also comprises: the spring perch between described recoil spring group and lower nut, described recoil spring group is passed to described lower nut by described spring perch with stressed.
Alternatively, described spring perch be shaped as annular, be socketed on the described suspension rod.
Alternatively, fixing for being spirally connected between described body skin and the suspension hook.
Alternatively, fixing for being spirally connected between described lower nut and the described suspension rod.
The present invention also provides a kind of hanging device, comprises above-mentioned each described suspension hook structure.
Compared with prior art, the present invention has the following advantages:
In the suspension hook structure of the embodiment of the invention; suspension hook is captiveed joint with body skin; body skin and be fixed between the lower nut on the suspension rod and be provided with the recoil spring group; in the lifting process; suspension hook is with the stressed body skin that passes to; body skin extruding recoil spring group; the recoil spring group is passed to lower nut and then is passed to suspension rod and flap seat stressed; under deep-sea or the operating mode of jolting; the recoil spring group will absorb consequent excessive power; guarantee the safety of hanging device, and be conducive to reduce the cold punching requirement of suspension hook structure and even whole hanging device.
In addition, in the suspension hook structure of the embodiment of the invention, also comprise be arranged at that shell is carried and flap seat between the erosion control spring assembly, in uninstall process, in a single day cargo load leaves suspension hook, the recoil spring group rushes at flap seat with quick jack-up body skin, and the erosion control spring assembly can absorb the excess energy that the recoil spring group recoils and produces fast, avoids body skin and flap seat to produce and impacts.
Description of drawings
Fig. 1 is the structural representation of the suspension hook structure of the embodiment of the invention.
The specific embodiment
The invention will be further described below in conjunction with specific embodiments and the drawings, but should not limit protection scope of the present invention with this.
Fig. 1 shows the structural representation of the suspension hook structure of present embodiment, comprising: suspension hook 1, body skin 2, recoil spring group 3, spring perch 4, lower nut 5, suspension rod 6, flap seat 7 and erosion control spring assembly 8.
Wherein, for captiveing joint, be specially in the present embodiment and be spirally connected between suspension hook 1 and the body skin 2, being shaped as of body skin 2 is cylindric, and its outer wall has screw thread, and suspension hook 1 is screwed onto with body skin 2 by this screw thread.The last bottom surface of body skin 2 all is provided with mounting hole, suspension rod 6 penetrate in the mounting hole and and body skin 2 between form and flexibly connect.
The upper end of suspension rod 6 is fixed on the flap seat 7, and fixedly there is lower nut 5 lower end, in the present embodiment, between lower nut 5 and the suspension rod 6 for being spirally connected.Spring perch 4 is arranged on the lower nut 5, and the be hit by a bullet annular that is shaped as of spring abutment 4 of present embodiment is socketed on the suspension rod 6.Recoil spring group 3 is arranged between body skin 2 and the spring perch 4, between spring perch 4 and lower nut 5 and the suspension rod 6 can be non-ly to captive joint or captive joint, but need to guarantee that spring perch 4 fixes with respect to the position of lower nut 5 and suspension rod 6.In addition, spring perch 4 can be so that the setting of recoil spring group 3 be more firm, and it is optional, and in other embodiments, recoil spring group 3 also can be set directly between body skin 2 and the lower nut 5.
As a preferred embodiment, also be provided with erosion control spring assembly 8 between body skin 2 and the flap seat 7.
In the lifting process, suspension hook 1 is stressed and pass to body skin 2 by screw thread, then body skin 2 pushes recoil spring groups 3, stressedly be passed to spring perch 4 along recoil spring group 3, spring perch 4 is with the stressed lower nut 5 that passes to, and then with the stressed suspension rod 6 that passes to, suspension rod 6 is again with the stressed flap seat 7 that passes to by screw thread for lower nut 5, last flap seat 7 can pass stressed via other devices such as suspension ring or steel ropes again, does not do too much expression herein.If load too fastly, above-mentioned actuating system will absorb consequent excessive power largely, to guarantee the safety of hanging device.
In uninstall process, in a single day cargo load leaves suspension hook, if uninstall process is too fast, recoil spring group 3 is with quick jack-up body skin 2 and rush at flap seat 7 so, this moment, erosion control spring assembly 8 can absorb recoil spring group 3 fast dischargings and the excess energy that produces, avoided producing between body skin 2 and the flap seat 7 impact.
In transportation, if take place unnecessary jolt and vibrate, recoil spring group 3 and erosion control spring assembly 8 will farthest absorb the energy that jolts and vibrate generation to guarantee that transportation steadily so.
In addition, present embodiment also provides a kind of hanging device that comprises suspension hook structure shown in Figure 1, and the suspension hook structure in Fig. 1, this hanging device can also have conventional hanging device in order to realize the needed miscellaneous part of conventional lifting function.
Though the present invention with preferred embodiment openly as above; but it is not to limit the present invention; any those skilled in the art without departing from the spirit and scope of the present invention; can make possible change and modification, so protection scope of the present invention should be as the criterion with the scope that claim of the present invention was defined.
