Detailed description of the invention
Lift preferred embodiment below, and come by reference to the accompanying drawings clearlyer intactly the utility model to be described.
As illustrated in figs. 2-7, a kind of anchor platform equipment for spitkit provided by the utility model, comprise hull 10, anchor recess 20, hawse pipe 30, anchor playscript with stage directions body 40, anchor chain 31 in hawse pipe extends to outside described hull 10 through anchor recess 20, anchor playscript with stage directions body 40 is made up of anchor platform outside face 41, left and right anchor platform side end face 412, and anchor platform outside face 41 is welded to form by upper and lower two pieces of panels 413 and middle one section of arc plate 414.
Wherein, left and right anchor platform side end face 412 is respectively provided with conical suface structure 50, and conical suface structure 50 is made up of upper and lower jigsaw 501 and the zone line conical suface 502 that is connected with upper and lower jigsaw.
The manufacturing process of conical suface structure is as follows:
The first step, determines shape and the size of conical suface structure.As in Figure 3-5, former anchor playscript with stage directions body is formed by upper and lower two pieces of flat boards and middle one section of arc plate butt welding, and the docking solder joint getting anchor platform side end face place is B, C.Well dock with anchor you face to make the newly-increased conical suface structure in anchor platform both sides, first get anchor you face circular arc summit A, to become α angle (α angle is 45 °) with the side end face of anchor platform in the horizontal surface at A place, ray projection is made to ship hull plate, obtain and outside plate intersection point O, connect OB, OC, the docking solder joint getting upper and lower two pieces of dull and stereotyped places, anchor platform side end face is E, namely three pieces of jigsaw that F so just determines composition conical suface structure 50 are gone up, the butt weld of lower jigsaw 501 and conical suface 502, pass through OA, OB, OC, OE, OH determines conical suface construction geometry model, wherein upper and lower two pieces of jigsaw OEB, OHC makes even plate, zone line OBAC gets tapered panel.
Second step, three pieces of jigsaw processing of composition conical suface structure.In workshop, process three pieces of jigsaw according to dimensional characteristic, the steel plate material of use requires consistent with former anchor playscript with stage directions body with thickness of slab.
3rd step, whether three pieces of jigsaw sizes that on-the-spot confirmation processes agree with the side end face of anchor platform, excision remainder punching, after confirmation, first by three pieces of jigsaw Combination Welding, as shown in Figure 7, the crescent moon increasing by one grade of transverse direction in conical suface inside configuration strengthens gusset, the installation site that crescent strengthens gusset depends on the circumstances, and the weld seam of jigsaw requires rounding in addition, forms good transition.
4th step, in the assembling stage, conical suface structure and anchor platform and ship hull plate are welded and fixed, and butt welded seam carries out grinding process.
As shown in Figure 2, the anchor platform equipment adopting above-mentioned steps to manufacture is in real ship uses, and when anchor chain skids off anchor platform time, anchor chain is subject to anchor self gravitation G and anchor chain tensile force f
p, make anchor chain produce the power F at a Ge Xiangmaotai center on the one hand, order about anchor chain and slide to Mao Tai center along conical suface.Overcoming friction drag on the other hand conical suface positive pressure Fn and makes anchor chain slide to the propulsive effort F1 of anchor platform.
As shown in Figure 6, as long as propulsive effort F1>f, anchor chain will slide to anchor platform.
Friction drag f=Fn* μ=(F1*tan θ) * μ
Wherein μ=0.18 (1.2 times that get steel coefficient of static friction)
f＝(F1*tanθ)*0.18
By F1>f
F1> (F1*tan θ) * 0.18 can be obtained
I.e. (θ <80 °) during tan θ <5.56, propulsive effort is greater than friction drag.
In addition, the crescent being provided with one grade of transverse direction in conical suface structure strengthens gusset 60, is fixed on inside conical suface structure.To guarantee the docking intensity of three pieces of jigsaw commissures.
Although the foregoing describe detailed description of the invention of the present utility model, it will be understood by those of skill in the art that these are only casehistorys, protection domain of the present utility model is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present utility model and essence, can make various changes or modifications to these embodiments, but these change and amendment all falls into protection domain of the present utility model.
