[0038] like Figure 1As shown, an embodiment of the present invention provides an anchor pulling test device with adjustable anchor lip posture, comprising a hull longitudinal inclination adjustment mechanism 1, an anchor chain barrel inclination adjustment mechanism 2, an anchor lip adjustment mechanism 3, a hull model bracket 5, an anchor angle adjustment mechanism 6, a hull transverse inclination adjustment hydraulic cylinder 9, an anchor system assembly and a hull model, wherein the anchor system assembly comprises a winch, a steel wire rope, an anchor, an anchor chain, an anchor lip 4 and an anchor chain barrel 201.

[0039] Combination Figures 2 to 4 The hull model bracket 5 has a symmetrical arrangement of a hull trim adjustment mechanism 1 at both ends thereof. The hull trim adjustment mechanism 1 comprises a lifting ring shaft 101 and an adjustable slider bearing seat 104. The adjustable slider bearing seat 104 comprises two door-type frames arranged side by side. The inner side of the door-type frames is provided with a slide groove up and down and a slider guide frame is slidably arranged. The slider guide frame has a vertical guide rail. A fixed plate is arranged on the outer side of the two door-type frames, and a push plate is arranged on the inner side. A first turbine-worm mechanism is installed on the fixed plate. The worm of the first turbine-worm mechanism is connected to the push plate, and the push plate is fixed to the two slider guide frames. Rotating the horizontal adjustment wheel 104a on the first turbine-worm mechanism can push the two slider guide frames to move along the slide groove.

[0040] The rear bearing slider 104c and the front bearing slider 104d are slidably arranged on the two slider guide rail frames, and the rear bearing slider 104c and the front bearing slider 104d are kept coaxially through the eye shaft 101. A second worm gear mechanism is fixed on the top of the rear bearing slider 104c and the front bearing slider 104d, and rotating the vertical adjustment wheel 104b on the second worm gear mechanism can make the rear bearing slider 104c and the front bearing slider 104d move up and down synchronously.

[0041] When the trim of the hull needs to be adjusted (for example, the hull is lower on the left and higher on the right), the vertical adjustment wheel 104b in the right hull trim adjustment mechanism 1 is turned to make the rear bearing slider 104c and the front bearing slider 104d rise vertically at the same time. Because the eye shafts 101 at both ends of the hull are on the same center line, the eye shafts 101 need to move closer to the center, so the horizontal adjustment wheel 104a is turned at the same time to make the rear bearing slider 104c and the front bearing slider 104d move horizontally toward the center at the same time. The trim adjustment method of the hull with the left side higher and the right side lower is the same.

[0042] A front eye bearing seat 102 and a rear eye bearing seat 103 are rotatably arranged on the eye shaft 101, and the hull model is fixed to the eye bearing seat by bolts. The cylinder end of the hull heel adjustment hydraulic cylinder 9 is fixed to the hull model bracket 5 through the second ball joint 11, and the rod end is fixed to the hull model through the first ball joint 10. When the hull heel adjustment hydraulic cylinder 9 is extended or shortened, the hull model can rotate around the two eye shafts 101, thereby adjusting the heel angle of the hull model, and different extensions correspond to different heel angles.

[0043] Combination Figures 5 to 11The anchor chain tube inclination adjustment mechanism 2 includes a horizontal adjustment electric cylinder 202 and a vertical adjustment electric cylinder 208. The anchor chain tube 201 is installed on the anchor chain tube support. The anchor chain tube support is divided into upper and lower parts. The upper part has an upper connecting plate 205 at the bottom and a lower connecting plate 206 at the top. A thrust shaft 207 is rotatably arranged on the lower connecting plate 206 through a thrust bearing 209. The upper connecting plate 205 is fixed to the thrust shaft 207 by bolts. A rear shaft 201c and a front shaft 201d are radially welded to the outer side of the upper end of the anchor chain tube 201, which are respectively assembled with the anchor chain tube rear bearing seat 203 and the anchor chain tube front bearing seat 204 provided on the upper part of the anchor chain tube support, so that the upper end of the anchor chain tube 201 is rotatably connected to the upper part of the anchor chain tube support.

[0044] The cylinder end of the vertical adjustment electric cylinder 208 is fixed to the electric cylinder bracket 8 in the hull model through a ball joint, and the rod end is fixed to the front ball joint base 201e on the anchor chain tube 201 through a ball joint. When the elongation of the vertical adjustment electric cylinder 208 is changed, the anchor chain tube 201 can rotate around the rear axis 201c and the front axis 201d in the vertical plane. The cylinder end of the horizontal adjustment electric cylinder 202 is fixed to the hull model through a ball joint, and the rod end is fixed to the rear ball joint base 201a on the anchor chain tube 201 through a ball joint. When the elongation of the horizontal adjustment electric cylinder 202 is changed, the anchor chain tube 201 can rotate around the thrust axis 207 in the horizontal plane, such as Fig.12 shown.

[0045] The anchor lip 4 is arranged at the lower end of the anchor chain tube 201, and the anchor lip adjustment mechanism 3 includes an anchor lip rotating ring seat 306, a ring seat driving mechanism and a three-cylinder parallel mechanism. The outer wall of the anchor chain tube 201 is vertically welded with a slide groove 201b, and the anchor lip rotating ring seat 306 includes a slip ring 306e rotatably arranged in the slide groove 201b. The ring seat driving mechanism includes a motor 302 and a driving sprocket 304, wherein the motor 302 is fixed to the surface of the anchor chain tube 201 through a motor bracket 301. After the motor 302 increases the torque through the reducer 303, it is connected to the sprocket shaft 311 of the driving sprocket 304 through a flange coupling 310, thereby outputting power to the driving sprocket 304. The bottom of the slip ring 306e is coaxially connected to a driven sprocket 306d, and the driving sprocket 304 and the driven sprocket 306d are connected through a chain 305, so that the motor 302 can drive the anchor lip rotating ring seat 306 to rotate around the axis of the anchor chain tube 201.

[0046] In order to prevent the driving sprocket 304 from axially moving, an axial end baffle 312 is provided at the tail of the sprocket shaft 311 , and the axial end baffle 312 is fixed to the tail of the sprocket shaft 311 by bolts 313 .

[0047] The three-cylinder parallel mechanism includes electric cylinders 307, 308 and 309 of the same model. The bottom of the slip ring 306e is provided with electric cylinder bases 306a, 306b and 306c in the circumferential direction, wherein the electric cylinder bases 306a and 306c are radially opposite to each other, and the electric cylinder base 306b is located in the middle of the electric cylinder bases 306a and 306c. In the three-cylinder parallel mechanism, the cylinder barrel end of the electric cylinder is fixed to the electric cylinder base through an I-type joint, and the push rod end is fixed to the ball joint base of the anchor lip 4 through a ball joint. At this time, the parallel motion of the three electric cylinders can control the three degrees of freedom of the anchor lip 4, including translation along the axis of the anchor chain barrel 201 (z direction) and rotation around the x and y axes. In addition, the anchor lip rotating ring seat 306 can drive the anchor lip 4 to rotate around the axis of the anchor chain barrel 201, so the anchor lip 4 has a total of 4 degrees of freedom that can be adjusted, such as Fig.13 shown.

[0048] like Fig.14 As shown, the O-XYZ coordinate system is established with the center of the three electric cylinder bases as the origin O, and the coordinate system o-xyz is established with the ellipse center of the anchor lip chamfer as the origin o. The Z axis and the z axis are on the axis of the anchor chain barrel, the X axis is parallel to the x axis, and the Y axis is parallel to the y axis. The length of the electric cylinder connected to the A1 base is L1, the length of the electric cylinder connected to the A2 base is L2, and the length of the electric cylinder connected to the A3 base is L3.

[0049] The coordinates of the three mobile sub-bases A1, A2 and A3 in the O-XYZ coordinate system are:

[0050]

[0051] The coordinates of the spherical joints a1, a2 and a3 in the o-xyz coordinate system are:

[0052]

[0053] Take the ZYX type Euler angle (α, β, γ),

[0054] cα=cosα,sα=sinα,cβ=cosβ,sβ=sinβ,cγ=cosγ,sγ=sinγ. When adjusting the angles of γ and β, one angle is kept at 0, α is fixed at 0, and the direction cosines of the moving coordinate system o-xyz relative to the fixed coordinate system O-XYZ are:

[0055]

[0056] P=[P X P Y P Z ] T represents the position vector of the origin o in the moving coordinate system o-xyz in the fixed coordinate system, and the coordinates C of the three spherical joints in the fixed coordinate system i for:

[0057] C i =Ra i +P(i=1,2,3)

[0058] From the above, we can calculate the lengths of the electric cylinder L1, L2, and L3 as:

[0059] L i =|C i -A i | (i=1,2,3).

[0060] The target position adjustment of the anchor lip can be achieved by controlling the corresponding electric cylinder through PLC according to the required electric cylinder length.

[0061] Combination Fig.15 The anchor angle adjustment mechanism 6 is arranged on the top of the hull model, including a chain guide roller base 7. A waist-shaped hole is opened on the chain guide roller base 7 and a front chain guide roller 601 and a rear chain guide roller 602 are installed by bolts. The anchor angle adjustment is achieved by adjusting the relative positions of the two chain guide rollers.

[0062] The anchor pulling test device provided in the embodiment of the present invention is made of steel as a whole, which is closer to the actual anchor pulling process.

[0063] According to the hull heel angle, the anchor chain barrel spatial inclination angle and the position and posture of the anchor lip required by the test conditions, the length of the hull heel adjustment hydraulic cylinder 9 and the adjustable slider bearing seat 104 are adjusted to achieve the target heel and heel angle adjustment of the hull, the length of the horizontal adjustment electric cylinder 202 and the vertical adjustment electric cylinder 208 are adjusted to achieve the target inclination angle adjustment of the anchor chain barrel, and the position and posture of the anchor lip are adjusted by the three-electric cylinder parallel mechanism and the motor 302.

[0064] After completing the setting of the anchoring angle, the spatial inclination of the anchor chain barrel and the position and posture of the anchor lip, the tail end of the anchor chain is fixed by the wire rope of the winch, and the winch is set to different speeds (generally eight are set, and the anchor chain linear speed is 28-250mm / s). At each speed, different hull transverse and longitudinal inclination angles are set, and the initial position of the anchor is fiddled with at will, and the fit between the anchor and the anchor lip at different anchor pulling speeds and different hull transverse and longitudinal inclination angles is recorded (preferably four-point contact). If the anchor and the anchor lip do not fit or are stuck, the anchor chain barrel inclination angle, the anchor lip position and the anchoring angle can be adjusted through this device, and the test is continued according to the above method until the anchor and the anchor lip can fit closely and no anchor jam occurs at different speeds and different hull transverse and longitudinal inclination angles.
