[0061] The fixed support provided by the present invention is installed on the carrier, and a placement groove for fixing the object to be transported can be formed through the variable-diameter openable and closable side block assembly, and the variable-diameter openable and closable side block assembly can adjust the diameter and height of the placement groove. The variable-diameter openable and closable side block assembly can also form a closed state that limits the vertical displacement of the object to be transported in the placement groove through the organic cooperation of various components, an open state that is convenient for transportation, and a guiding state that is convenient for placing the object to be transported.

[0062] As shown in the figure, the variable diameter adjustable quick installation offshore platform transport fixed support provided by the present invention includes four components: a connecting base plate 100, a rotatable base 200, a variable diameter openable and closable side stop assembly 300, and a top connecting plate 400.

[0063] The connecting base plate 100 is fixed on the carrier, and the rotatable base 200 is rotatably arranged on the connecting base plate 100. The rotatable base 200 is provided with a plurality of slide grooves 221 equidistantly arranged along the circumference. The plurality of slide grooves 221 are arranged radially along the rotatable base 200.

[0064] The variable diameter openable and closable side guard assembly 300 includes a plurality of side guard bases 310 , a plurality of conversion members 320 , and a plurality of surrounding rods 330 ;

[0065] A slider 314 is provided at the bottom of the side block base 310 and is adapted to fit into the chute 221. A plurality of side block bases 310 are movably disposed in the chute 221 via the slider 314. The plurality of side block bases 310 are distributed in a ring shape on the rotatable base and together form a placement groove 315 for placing objects to be transported.

[0066] A plurality of surrounding rods 330 are connected to the side barrier base 310 via conversion members 320. The conversion members 320 are vertically adjustable and arranged on the side barrier base 310 and are rotatably connected to the side barrier base 310 via a multi-link. One end of the surrounding rod 330 is rotatably connected to the conversion member 320. The surrounding rod 330 can be formed into two states: folded and unfolded by rotating relative to the conversion member 320. The conversion member 320 can be formed into an open state, a guide state, and a closed state by rotating relative to the side barrier base 310 and cooperating with the surrounding rod 330.

[0067] When open, Figure 6 When the conversion member 320 is rotated relative to the side stop base 310 to the lowest horizontal point, the conversion member 320 is placed on the rotatable base 200. At this time, the surrounding rod 330 is rotated to form a folded state, and the conversion member 320 cooperates with the surrounding rod 330 to form an open state for easy transportation;

[0068] When the guidance state is Figure 7 The conversion member 320 is rotated to move vertically upward relative to the open state, and a plurality of conversion members 320 are distributed around the placement groove 315 in an inclined state. At this time, the surrounding rod 330 is in a folded state, and the conversion member 320 cooperates with the surrounding rod 330 to form a guiding state, so as to guide the object to be transported when entering the placement groove 315;

[0069] When closed, Figure 5 The conversion member 320 can drive the surrounding rod 330 to be relatively close to the placement groove 315 by rotating to change the inclination angle relative to the guide state. One end of several surrounding rods 330 is formed into an expanded state by rotation, and the other ends of several surrounding rods 330 are connected through the top connecting plate 400. The conversion member 320 cooperates with the surrounding rod 330 to form a closed state to vertically fix the object to be transported placed in the placement groove 315.

[0070] The specific structure of each component is described below with reference to the accompanying drawings.

[0071] like Figure 4The rotatable base 200 includes a base body 210 and a plurality of connecting portions 220 connected to the base body 210. The base body 210 is circular, and the plurality of connecting portions 220 are equidistantly distributed along the circumference of the base body 210. The connecting portions 220 are provided with a slide groove 221. The slide groove 221 is arranged along the radial direction of the base body 210 and extends to the base body 210.

[0072] The bottom of the chute 221 is provided with a bolt group 221a along the length direction, and a second bolt group 221b is equidistantly provided on both sides of the bolt group 221a on the connecting portion 220 and the base body 210;

[0073] A rotation shaft 211 is provided at the center of the bottom of the base body 210 , and a third bolt group 221 c is provided along the circumference of the rotation shaft 211 on the base body 210 .

[0074] like Figure 3 The rotatable base 200 of such a structure is rotatably connected with the connecting base plate 100. The connecting base plate 100 is a circular base plate with an opening in the middle. A ball bearing 110 is provided in the opening. The connecting base plate 100 is provided with a fourth bolt group 120, a fifth bolt group 130 and a sixth bolt group 140 corresponding to the bolt group 221a, the second bolt group 221b and the third bolt group 221c.

[0075] The rotating shaft 211 at the bottom of the base body 210 is connected to the ball bearing 110 in the connecting base plate 100 to achieve a rotatable connection between the rotatable base 200 and the connecting base plate 100. When the two are rotated relative to each other to a suitable position, the rotatable base 200 is fixed to the connecting base plate 100 by using bolts to pass through the third bolt group 221c on the base body 210 and the sixth bolt group 140 on the connecting base plate 100.

[0076] The rotation of the rotatable base 200 relative to the connecting base 100 can be rotated according to the actual opening direction of the supporting part (such as the legs) of the object to be transported, so as to avoid possible interference from rods.

[0077] Further, if Figure 5 , the side block base 310 includes a movable bottom plate 311, a side block 312, and two reinforcing plates 313;

[0078] like Figure 8When the cam 314 is in the closed position, the cam 314a is in the closed position, and the cam 314b is in the closed position, so that the cam 314b can be fixed to the cam 314b by the screw thread of the cam 314a.

[0079] The side guard 312 is vertically arranged on the top of the movable base plate 311. The side surface of the side guard 312 close to the center of the base body 210 is arc-shaped. The movable base plates 311 are arranged on the slide groove through the slider 314. The side guards 312 cooperate to form a circular placement groove 315.

[0080] The bottoms of the two reinforcing plates 313 are vertically connected to the movable bottom plate 311, and one side is perpendicular to and connected to the other side of the side block 312. The tops of the two reinforcing plates 313 are sequentially provided with rotation holes 313a. A plurality of adjustable horizontal shafts 316 are sequentially provided vertically between the two side blocks 312.

[0081] Further, if Figure 5 , Figure 9 The conversion member 320 is a frame-shaped structure, and a plurality of connecting shafts 321 are sequentially provided on the middle portion thereof. The connecting shaft 321 at the top is movably connected to the surrounding rod 330, and the connecting shaft 321 at the second top is movably connected to one end of the support rod 322. The other end of the support rod 322 is provided with an opening. The remaining connecting shafts 321 are movably connected with parallel links 323. The plurality of parallel links 323 are arranged in parallel, and the parallel links 323 are movably connected to the adjustable horizontal axis 316 between the two reinforcing plates 313 so that the conversion member 320 can be rotated relative to the side stop base 310. By connecting the plurality of parallel links 323 to different adjustable horizontal axes 316 between the two reinforcing plates 313, the vertical position of the conversion member 320 relative to the side stop base 310 can be adjusted.

[0082] After the conversion member 320 is rotated relative to the side block base 310, the other end of the support rod 322 is placed in the rotation hole 313a between the tops of the two reinforcing plates 313, and the opening at one end of the support rod 322 is coaxial with the two rotation holes 313a. The fastener 324 is passed through the rotation hole 313a and the opening and fixed to fix the support rod 322 to the conversion member 320.

[0083] Further, if Figure 5 The surrounding rod 330 is arc-shaped, and one end is movably connected to the top connecting shaft 321 among the plurality of connecting shafts 321. One end of the surrounding rod 330 rotates around the connecting shaft 321 so that the other end is at the lowest horizontal point to form a folded state, and the other end is at the highest horizontal point to form an unfolded state;

[0084] A notch 331 is provided at one end of the surrounding rod 330, and a connecting hole 332 is provided at the end. When the surrounding rods 330 in the variable-diameter openable and closeable side block assemblies 300 are all in the unfolded state, the other ends of the surrounding rods 330 are in contact and are all located at the top of the placement groove 315. The notches 331 at the ends of the surrounding rods 330 form a mounting groove 333 for the top connecting plate 400 to be placed.

[0085] like Figure 10 The top connecting plate 400 is provided with several second connecting holes 410 corresponding to the connecting holes 332. The number of the second connecting holes 410 is consistent with the number of the surrounding rods 330. The top connecting plate 400 is placed in the mounting groove 333 and is connected to the several surrounding rods 330 through fasteners respectively to connect the several surrounding rods 330 into a whole.

[0086] Furthermore, if Figure 2 In order to obtain the tension applied to the fixed support and the real-time status information of the support in real time, this solution provides a pressure sensor 500 between the top connecting plate 400 and the surrounding rod 330. A bolt hole is provided in the center of the surrounding rod 330, and the bolt hole is connected to the pressure sensor 500. The pressure sensor 500 is located in the installation groove, and the two end faces are respectively abutted against the bottom of the installation groove and the bottom of the top connecting plate 400. The pressure sensor 500 can display the tension applied to the support in real time and alarm when it exceeds the preset value.

[0087] Furthermore, if Figure 5 In order to improve the reliability of the overall connection of the support, a horizontal plate 312a perpendicular to the top of the side block 312 is provided, and bolt holes are provided on the horizontal plate 312a. An annular reinforcing rib 600 is provided between two adjacent side blocks 312 in the side block base 310. The two ends of the annular reinforcing rib 600 are respectively fixedly connected to the bolt holes on the horizontal plates 312a at the top of the two adjacent side blocks 312. The several annular reinforcing ribs 600 are used to connect the several side blocks 312 into a whole.

[0088] Furthermore, if Figure 1The variable-diameter adjustable quick-install offshore platform transport fixed support provided by this solution also includes an inner lining rubber pad 700, which is inserted in the placement groove 315. It includes a side ring pad and a bottom disc pad connected together. The bottom disc pad is arranged on a rotatable base 200 between several side block bases 310. The side ring pad is annular and fits with the side blocks 312 in the several side block bases 310, which can block the gaps between adjacent side blocks 312. In this way, when the object to be transported is placed in the placement groove 315, it can directly avoid contact with the support, reduce transportation vibration and friction, and ensure that the object to be transported is tightly fitted with the side block 312.
