Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0069] Please see Figure 1-5 This utility model provides a technical solution: a concrete wind turbine tower transportation and fixing device, comprising:

[0070] The splicing base plate 1 has concrete wind turbine tower support plates 4 fixedly assembled on both the left and right sides of its upper surface.

[0071] The bottom surface of the splicing base plate 1 is equipped with base plate fixing components 3 on both the left and right sides;

[0072] The lower end of the base plate fixing component 3 is welded to the transport vehicle plate or the ship deck, and its upper end is located on the outside of the concrete wind turbine tower support plate 4 on the same side.

[0073] A first splicing connecting rod 5 is screwed to the rear side between the two concrete wind turbine tower support plates 4 on both sides, and a first connecting bend 9 is rotatably assembled on its right end.

[0074] A second splicing connecting rod 6 is screwed to the front side between the two concrete wind turbine tower support plates 4 on both sides, and a second connecting elbow 10 is rotatably assembled on its left end.

[0075] The upper ends of the first connecting bend 9 and the second connecting bend 10 are bent laterally and facing each other.

[0076] The upper ends of the first connecting bend 9 and the second connecting bend 10 are respectively fixedly mounted with conical positioning blocks 7 on the same axis.

[0077] A transverse sliding guide structure 8 is installed between the outer wall of the conical positioning block 7 and the outer side of the concrete wind turbine tower support plate 4 on the same side.

[0078] The upper ends of the concrete wind turbine tower support plates 4 on both sides support the concrete wind turbine tower, and the inner end of the conical positioning block 7 is inserted and positioned on the inner ring surface of the concrete wind turbine tower on the same side.

[0079] Specifically, in this embodiment, the splicing base plate 1 and the concrete wind turbine tower support plate 4 are made of steel to ensure support strength;

[0080] Furthermore, the base plate fixing assembly 3 is welded and fixed to the transport vehicle board or the ship deck, and the two ends of the spliced ​​base plate 1 are fixed by the base plate fixing assembly 3. The concrete wind turbine tower is supported by the concrete wind turbine tower support plates 4 on both sides of the upper end of the spliced ​​base plate 1.

[0081] More specifically, the conical positioning block 7 on the same side is supported and guided by the transverse sliding guide structure 8 set on the outer wall of the concrete wind turbine tower support plate 4 on both sides. The first splicing connecting rod 5 screwed to the concrete wind turbine tower support plate 4 on both sides drives the first connecting bend 9 to push and pull the conical positioning block 7 on the same side along the transverse sliding guide structure 8. The second splicing connecting rod 6 screwed to the concrete wind turbine tower support plate 4 on both sides drives the second connecting bend 10 to push and pull the conical positioning block 7 on the same side along the transverse sliding guide structure 8. The tip of the conical positioning block 7 is inserted into the inner ring surface of the concrete wind turbine tower. Both sides are positioned by the insertion of the conical positioning block 7, which provides stable limiting and fixing for the concrete wind turbine tower, ensuring its stability during transportation.

[0082] It is understandable that the concrete wind turbine tower support plate 4 is manufactured according to the concrete wind turbine tower to be fixed, and the inner diameter of the semi-circular groove 42 is the same as the outer shape of the concrete wind turbine tower.

[0083] In some embodiments, the conical positioning block 7 includes:

[0084] The outer side of the circular plate 71 is fixedly assembled to the transversely bent end of the first connecting bend 9 and the second connecting bend 10 via a flange at the middle part of its outer side.

[0085] A hollow frustum 72 is attached and fixed to the inner side of the circular plate 71, with its smaller end facing inward.

[0086] A rubber layer 73 is attached to the outer wall of the hollow truncated cone 72, and its outer wall is in contact with the inner ring surface of the concrete wind turbine tower.

[0087] Specifically in this embodiment, the hollow frustum 72 is made of aluminum alloy, which combines lightweight and strength, and the rubber layer 73 is made of wear-resistant elastic rubber.

[0088] Furthermore, a rubber layer 73 is provided on the outer wall of the hollow truncated cone 72. After the hollow truncated cone 72 is inserted into the inner ring surface of the concrete wind turbine tower, the rubber layer 73 adheres to the inner wall of the concrete wind turbine tower. The hollow truncated cone 72 is inserted until it can no longer move. At this time, the rubber layer 73 is compressed and deformed to ensure the firmness of the contact.

[0089] More specifically, the maximum outer diameter of the hollow frustum 72 is greater than the inner diameter of the concrete wind turbine tower, and the minimum outer diameter of the hollow frustum 72 is less than the inner diameter of the concrete wind turbine tower.

[0090] In some embodiments, the lateral sliding guide structure 8 includes:

[0091] There are two horizontal plates 82 distributed at the front and back, and the inner ends of the two horizontal plates 82 are fixedly connected to the outer wall of the conical positioning block 7 on the same side.

[0092] Guide rods 81 are vertically fixedly installed on the front and rear sides of the outer wall of the concrete wind turbine tower support plate 4, corresponding to the horizontal plates 82.

[0093] A through hole 83 is provided on the outer wall of the horizontal plate 82 corresponding to the guide rod 81, and the outer end of the guide rod 81 passes through the corresponding through hole 83.

[0094] Specifically, in this embodiment, the guide rod 81 is made of steel, and the end weld is reinforced with additional welding to ensure connection strength;

[0095] Furthermore, the front and rear guide rods 81 support the horizontal plate 82 that slides on it, thereby supporting the conical positioning blocks 7 on the same side of the horizontal plates 82 that are fixed on both sides. The horizontal plate 82 can slide along the guide rods 81 and guide the conical positioning blocks 7 on the same side.

[0096] In some embodiments, the splicing base plate 1 includes;

[0097] Left base plate 11 and right base plate 12;

[0098] The right side of the left base plate 11 is integrally formed with a first wedge-shaped slider 13 along the length direction;

[0099] A first wedge-shaped groove 14 is provided on the left side of the right base plate 12 along the length direction;

[0100] Splicing panel 15, adjacent splicing panels 15 are spliced ​​end to end;

[0101] After splicing, the left and right ends of the splicing plate 15 are respectively spliced ​​with the first wedge slider 13 and the first wedge groove 14.

[0102] Specifically in this embodiment, the splicing plate 15 used on the left and right sides of the left bottom plate 11 and the right bottom plate 12 is selected according to the length of the concrete wind turbine tower to ensure that the length of the concrete wind turbine tower support plate 4 does not exceed half the length of the concrete wind turbine tower itself.

[0103] Furthermore, adjust the spacing between the left base plate 11 and the right base plate 12 according to the number of splicing panels 15 selected, and then splice the splicing panels 15 together. If there is only one splicing panel 15, skip this step. Then splice the two ends of the spliced ​​splicing panel 15 to the left base plate 11 and the right base plate 12 respectively.

[0104] It is understandable that the above splicing is achieved through the sliding engagement of wedge-shaped grooves and wedge-shaped sliders.

[0105] In some embodiments, the splicing panel 15 includes:

[0106] The flat plate 151 has a second wedge-shaped groove 152 on its left side along the corresponding first wedge-shaped slider 13;

[0107] The right side of the flat plate 151 is integrally formed with a second wedge-shaped slider 153 corresponding to the first wedge-shaped groove 14;

[0108] The second wedge-shaped slider 153 of the splicing plate 15 is slidably engaged in the second wedge-shaped groove 152 of the adjacent splicing plate 15;

[0109] The second wedge-shaped groove 152 of the leftmost splicing plate 15 is slidably sleeved on the outside of the first wedge slider 13;

[0110] The second wedge-shaped slider 153 of the rightmost splicing plate 15 is slidably engaged in the first wedge-shaped groove 14.

[0111] Specifically, in this embodiment, a second wedge-shaped groove 152 and a second wedge-shaped slider 153 are respectively provided at both ends of the plate 151, and adjacent plates 151 are spliced ​​together by the cooperation of the second wedge-shaped groove 152 and the second wedge-shaped slider 153.

[0112] In some embodiments, the first splicing connecting rod 5 includes:

[0113] The first screw 51 is fixedly connected to the adjacent first screws 51 by flanges at both ends;

[0114] The left end of the first screw 51 is fixedly connected to the second screw 52 via a flange. The left end of the second screw 52 is screwed and passes through the corresponding reserved internal thread through hole on the concrete wind turbine tower support plate 4 on the same side.

[0115] The right end of the first screw 51 is fixedly connected to the third screw 53 via a flange. Its right end is screwed and passes through the corresponding reserved internal thread through hole on the concrete wind turbine tower support plate 4 on the same side.

[0116] The right end of the third screw 53 is rotatably connected to the lower end of the first connecting bend 9.

[0117] Specifically in this embodiment, multiple first screws 51 are spliced ​​together end to end by flanges and bolts. Then, the two ends of the spliced ​​first screws 51 are still fixedly connected to the second screws 52 and the third screws 53 by flanges and bolts. The number of first screws 51 can be single.

[0118] Furthermore, the number of first screws 51 selected is adjusted according to the splicing length of the splicing base plate;

[0119] It is understandable that rotating the left end of the second screw 52 drives the connected first screw 51 and third screw 53 to rotate. The first screw 51, the second screw 52 and the third screw 53 have the same thread direction and thread pitch. The thread pitch of the reserved internal thread through holes on the concrete wind turbine tower support plates 4 on both sides is also the same. The second screw 52 and the third screw 53 match. The second screw 52 and the third screw 53 rotate and are screwed in or out of the reserved internal thread through holes on the corresponding concrete wind turbine tower support plates 4. Screwing in corresponds to moving to the right and screwing out corresponds to moving to the left, thereby driving the first connecting bend 9 and the conical positioning block 7 on the same side to move along the guiding direction of the transverse sliding guide structure 8 on the same side.

[0120] In some embodiments, the second splicing connecting rod 6 includes:

[0121] The fourth screw 61 is connected to the adjacent fourth screws by flanges at both ends;

[0122] The left end of the fourth screw 61 is fixedly connected to the fifth screw 62 via a flange. Its left end is screwed and passes through the corresponding reserved internal thread through hole on the concrete wind turbine tower support plate 4 on the same side.

[0123] The left end of the fifth screw 62 is rotatably connected to the lower end of the second connecting bend 10;

[0124] The right end of the fourth screw 61 is fixedly connected to the sixth screw 63 via a flange. The right end of the sixth screw 63 is screwed and passes through the corresponding reserved internal thread through hole on the concrete wind turbine tower support plate 4 on the same side.

[0125] Specifically in this embodiment, multiple fourth screws 61 are spliced ​​together end to end by flanges and bolts. Then, the two ends of the spliced ​​fourth screws 61 are still fixedly connected to the fifth screw 62 and the sixth screw 63 by flanges and bolts. The number of fourth screws 61 can be a single one.

[0126] Furthermore, the number of fourth screws 61 selected is adjusted according to the splicing length of the splicing base plate;

[0127] It is understandable that rotating the right end of the sixth screw 63 drives the connected fourth screw 61 and fifth screw 62 to rotate. The thread direction and thread pitch of the fourth screw 61, fifth screw 62 and sixth screw 63 are the same. The thread pitch of the reserved internal thread through holes on the concrete wind turbine tower support plates 4 on both sides is also the same and matches the fifth screw 62 and sixth screw 63. The fifth screw 62 and sixth screw 63 rotate and are screwed in or out of the reserved internal thread through holes on the corresponding concrete wind turbine tower support plates 4. Screwing in corresponds to leftward movement, and screwing out corresponds to rightward movement, thereby driving the second connecting bend 10 and the conical positioning block 7 on the same side to move along the guiding direction of the transverse sliding guide structure 8 on the same side.

[0128] In some embodiments, the concrete wind turbine tower support plate 4 includes:

[0129] Vertical plate 41 is fixedly assembled to the upper surface of splicing base plate 1 along the width direction;

[0130] A semi-circular groove 42 is provided at the upper end of the vertical plate 41, and the lower end of the concrete wind turbine tower is inserted into the semi-circular groove 42. The semi-circular groove 42 is provided corresponding to the outer diameter of the concrete wind turbine tower.

[0131] In some embodiments, baffles 2 are attached and fixed to the rear walls of the left bottom plate 11 and the right bottom plate 12;

[0132] The rear end of the splicing panel 15 abuts against the front wall of the baffle 2.

[0133] Specifically in this embodiment, the baffle 2 is glued to the rear ends of the left bottom plate 11 and the right bottom plate 12, and can be torn off to facilitate length adjustment of the spliced ​​bottom plate 1;

[0134] Furthermore, the baffle 2 can be selected in different lengths according to the length of the splicing base plate 1 to ensure that it can be pasted and fixed to the rear end of the left base plate 11 and the right base plate 12;

[0135] More specifically, by setting the baffle 2, the rear end of the splicing panel 15 is blocked during the splicing process. When the rear end of the splicing panel 15 abuts against the baffle 2, the wedge-shaped slider during the splicing process is completely inserted into the wedge-shaped groove.

[0136] In some embodiments, the base plate fixing assembly 3 includes:

[0137] The steel plate 31 has grooves on the left and right sides of the bottom surface of the splicing base plate 1 corresponding to the steel plate 31, and the steel plate 31 is inserted into the corresponding grooves.

[0138] Steel plate 31 is welded and fixed to the transport vehicle deck or ship deck;

[0139] The upper surface of the steel plate 31 is uniformly and vertically fixed with the seventh screw 32, the upper end of which penetrates the splicing base plate 1;

[0140] The upper end of the outer wall of the seventh screw 32 is screwed with an anti-loosening nut 33, and its lower end abuts against the upper surface of the splicing base plate 1.
