See fig. 1-6.

The invention is an improvement made on the basis of Chinese invention patent application with the patent application number of 202210050903.5 and the patent name of the invention is offshore wind turbine installation equipment.

The invention provides an electric power tower mounting device, which comprises:

the device comprises a mounting platform 1, wherein an abdicating groove 11 is formed in the mounting platform 1, a docking station 15 is positioned in the abdicating groove 11, and a base rod 2 enters the docking station 15 through the abdicating groove 11;

the supporting platform 3 is arranged on the mounting platform 1 and is used for supporting the tower column 8 and driving the tower column 8 to enter and exit the butt joint station 15;

the holding components 4 are fixed at the bottom of the mounting platform 1, at least three holding components are arranged, the holding components are respectively and symmetrically distributed on the periphery of the butt joint station 15, resultant force is generated in all directions to hold the base rod 2 at the butt joint station 15 tightly, and the distances from the end parts of the holding components to the center of the butt joint station 15 are equal;

the supporting legs 5 are arranged at the bottom of the mounting platform 1, and when each holding component holds the base rod 2 tightly, the reaction force on the holding component can push the mounting platform 1 to generate displacement relative to the supporting legs 5 or the mounting platform 1 drives the supporting legs 5 to generate displacement;

the C-shaped installation tower 6 is arranged on the top surface of the installation platform 1 and surrounds the docking station 15, and the center of the docking station 15 is superposed with the center of the installation tower 6;

the limiting device is arranged on the installation tower 6, so that the tower column 8 in the installation tower 6 is kept vertical and the tower column 8 is limited in the vertical direction;

and the first telescopic part 7 is connected with the mounting tower 6 and used for pushing the mounting tower 6 to approach and depart from the mounting platform 1 in the vertical direction.

In specific implementation, when the tower column 8 is installed, the base rod 2 enters the docking station 15 through the abdicating groove 11, then the clasping assemblies 4 combine force in all directions to clasp the base rod 2 at the docking station 15, and because the distances from the end parts of the clasping assemblies 4 to the center of the docking station 15 are equal and fixed on the mounting platform 1, when the base rod 2 is not located at the center of the docking station 15, the clasping assemblies 4 corresponding to one side of the base rod 2, and the reaction force of the clasping assemblies can drive the mounting platform 1 to move, so that the base rod 2 is located at the center of the docking station 15.

Then, moving the bearing platform 3 out of the docking station 15, vertically hoisting the tower column 8 onto the bearing platform 3 by means of small hoisting equipment, and driving the tower column 8 to return to the docking station 15 by the bearing platform 3; then, the limiting device is started to limit the tower column 8 at the butt joint station 15, and then the first telescopic part 7 is started to lift the installation tower 6 together with the limiting device and the tower column 8 upwards to a height higher than one tower column 8; then the supporting platform 3 moves out of the docking station 15 again and transfers the next section of the tower column 8 to the docking station 15, and at the moment, the first telescopic part 7 drives the mounting tower 6 to fall down, so that the tower column 8 limited by the limiting device falls to be aligned with the tower column 8 on the supporting platform 3 and is spliced; then the limiting device is withdrawn, the first telescopic part 7 drives the mounting tower 6 to move downwards to the bearing platform 3, and at the moment, the gravity of the spliced tower columns 8 is completely applied to the bearing platform 3 and is supported by the bearing platform 3; then the first telescopic part 7 drives the mounting tower 6 and the limiting device to move downwards to the lowest tower column 8, and then the limiting device is started again to limit the tower column 8 on the bearing platform 3; then the first telescopic part 7 is started again to lift the installation tower 6 together with the limiting device and the spliced tower columns 8 upwards to a height higher than that of one tower column 8; and the process is repeated until all the tower columns 8 are spliced together.

After all the tower columns 8 are spliced together, the bearing platform 3 moves out of the butt joint station 15, the mounting tower 6 drives the limiting device and the spliced tower columns 8 to move downwards through the first telescopic part 7, and the limiting device and the spliced tower columns 8 fall on the base rods 2 at the butt joint station 15 to be spliced with the base rods 2.

It should be noted that, because the position of the installation tower 6 relative to the installation platform 1 is fixed, the center of the docking station 15 and the center of the installation tower 6 can be designed to be in the same line during the manufacturing process of the equipment, so that the tower column 8 in the installation tower 6 can be automatically coaxial with the base rod 2; this is a simple and quick way compared to the coaxial alignment of the original patent.

When the tower column 8 is aligned with the screw hole on the base rod 2, a scribing alignment mode in the prior art can be adopted, namely, a line is scribed at the corresponding position of the base rod 2 and the mounting platform 1, when the mounting platform 1 is in place, firstly, the scribing line on the mounting platform 1 is aligned with the scribing line on the base rod 2, and the angle of the mounting platform 1 relative to the base rod 2 is ensured to be fixed. Then because the angle of the tower column 8 relative to the installation platform 1 is fixed (because the limiting device in the prior art limits the tower column 8 in the vertical direction in an inserting mode, the angle of the tower column 8 relative to the installation tower 6 and the installation platform 1 is a fixed value), when the installation platform 1 is aligned with the base rod 2, the tower column 8 is driven to be indirectly aligned with the base rod 2, so that the tower column 8 in the installation tower 6 cannot be dislocated with the base rod 2, and the screw holes are aligned.

It should be noted that when the mounting platform 1 is displaced relative to the leg 5, the leg 5 and the mounting platform 1 may be slidably engaged in this manner. When the mounting platform 1 drives the supporting legs 5 to displace, in this way, rollers or sliding parts can be arranged below the supporting legs 5, so that the supporting legs 5 move together with the mounting platform 1.

It should be noted simultaneously that when mounting platform used as offshore floating platform, this application can use when installation offshore wind power generation machine, under the effect of the holding power of landing leg and each holding subassembly, the ability that floating platform resisted toppling improves greatly for very little that floating platform can be built reduces floating platform's manufacturing cost. When this application uses on land, mountain region, can make this application modularization detachable assemble together to the destination is transported to the modular mode, then assembles, and its transportation problem that not only can solve equipment can also be solved when installing large-scale aerogenerator on the mountain region, and inconvenient problem is come in and go out to large-scale crane.

Since the supporting platform is disclosed by the prior art, it is not described herein in detail, and the supporting platform in the offshore wind turbine installation equipment is directly used with the patent application No. 202210050903.5 with the patent name of 202210050903.5.

Preferably, the hoisting equipment can be integrated on the mounting platform for the equipment to use when hoisting each section of tower column.

In an embodiment, since the spliced towers 8 are heavy, in order to prevent the tower 3 from being damaged by the crushed tower 8, the following technical means are adopted:

the C-shaped installation tower 6 is divided into an upper tower body 61 and a lower tower body 62, the upper tower body is arranged above the lower tower body, and a second telescopic part 63 is arranged on the installation tower 6 and used for pushing the lower tower body 62 to be close to or far away from the upper tower body 61 in the vertical direction;

the limiting device comprises a first limiting component and a second limiting component, wherein the first limiting component is arranged on the upper tower body 61 and is used for keeping the tower column 8 in the installation tower 6 vertical and limiting the tower column 8 in the vertical direction; the second limiting component is arranged on the lower tower body 62 and used for limiting the tower column 8 in the installation tower 6 in the vertical direction.

In specific implementation, when the first telescopic part 7 drives the mounting tower 6 together with the limiting device and the tower column 8 to fall to align with the tower column 8 on the supporting platform 3 and splice, the falling distance of the first telescopic part 7 is controlled, so that the upper tower column 8 and the lower tower column 8 are just butted together (a gap can be formed in the height direction), and at the moment, the upper tower column 8 and the lower tower column 8 are preliminarily spliced by a screw rod; then the second telescopic part 63 pushes the lower tower body 62 to move downwards, and then the second limiting assembly is started to limit the tower column 8 on the bearing platform 3; then the first telescopic part 7 drives the mounting tower 6 to move upwards to enable the spliced tower column 8 to integrally move upwards and separate from the bearing platform 3; the first limiting assembly releases the limit of the corresponding tower column 8 in the vertical direction and moves downwards, and because the upper tower column 8 does not have the limit in the vertical direction at the moment, the upper tower column 8 moves downwards to be in close contact with the primarily spliced tower column 8 below under the action of gravity, and at the moment, the upper tower column 8 and the lower tower column 8 can be further connected, so that the upper tower column 8 and the lower tower column 8 are connected together as required; because the first limiting assembly can also enable the tower column 8 in the installation tower 6 to be kept vertical, the tower column 8 does not need to be inclined at the moment; first spacing subassembly continues to carry on spacingly to the vertical direction of pylon 8 after the concatenation is accomplished, then first extensible part 7 drives installation tower 6 and upwards rises to the height that is higher than a pylon 8.

By the design, the bearing platform can only bear the weight of one section of tower column, the bearing platform is effectively prevented from being crushed by a plurality of spliced tower columns, and meanwhile, the design requirement of the bearing platform is lowered.

In an embodiment, the first limiting assembly comprises a righting component 64 and a first inserting component 65, wherein the righting component 64 is used for keeping the tower column 8 vertical, and the first inserting component 65 is used for being inserted on the tower column 8 to limit the vertical direction of the tower column 8; the second limiting assembly comprises a second inserting part 66 which is inserted on the corresponding tower column 8 to limit the vertical direction of the tower column 8. Since the centering member 64, the first inserting member 65 and the second inserting member 66 are all disclosed in the prior art, and the patent application No. 202210050903.5 entitled centering device and inserting device in the offshore wind turbine installation device can be directly adopted, so that the details are not repeated herein.

In one embodiment, a plurality of guide posts 12 are provided on the mounting platform 1 at positions corresponding to the mounting towers 6, and each guide post 12 is slidably engaged with the mounting tower 6 in the vertical direction. Design like this, play the guide effect to the installation tower, avoid the installation tower at the in-process skew of going up and down.

In one embodiment, each clasping assembly 4 comprises a pushing member 41 and a push plate 42, the pushing member 41 being adapted to move the push plate 42 towards and away from the docking station 15. Wherein, the pushing ends of the pushing components 41 have equal distance to the center of the docking station 15 and are fixed on the mounting platform 1.

In specific implementation, when each pushing component 41 pushes the pushing plate 42, each pushing plate 42 forms a ring sleeved on the outer side of the base rod 2, and because the distances from the pushing ends of each pushing component 41 to the centers of the docking stations 15 are equal and fixed on the mounting platform 1, when the base rod 2 is not located at the center of the docking station 15, the pushing component 41 corresponding to the side of the base rod 2 deviating to the center will drive the mounting platform 1 to move due to the reaction force of the pushing component 41, so as to ensure that the base rod 2 is located at the center of the docking station 15. Because the position of the installation tower 6 in the original patent is fixed relative to the installation platform 1, the center of the butt joint station 15 and the center of the installation position in the installation tower 6 can be designed on the same straight line in the equipment manufacturing process, and thus, the tower rod positioned at the installation position can be automatically coaxial with the base rod 2 when moving to the butt joint station 15; compared with the coaxial alignment mode in the original patent, the mode is simple and quick.

Preferably, each pushing member 41 can be selected from a pneumatic pushing member, a hydraulic pushing member or an electric pushing member in the prior art.

In one embodiment, the top surface of each leg 5 is in sliding fit with the mounting platform 1, a groove 51 is formed at the top end of each leg 5, a position of the mounting platform 1 corresponding to the groove 51 is provided with a limiting column 13, and the diameter of the limiting column 13 is smaller than that of the corresponding groove 51 and extends into the groove 51; in the gap between the groove 51 and the limit column 13, elastic pieces 52 are uniformly distributed along the peripheral side of the limit column 13.

In a specific implementation, the elastic members 52 uniformly distributed on the peripheral side of the position-limiting post 13 apply a pushing force to the position-limiting post 13, so that the position-limiting post 13 is located at the center of the groove 51 in a normal state. Since the recess 11 for the base shaft 2 is only slightly larger than the base shaft 2, the displacement between the leg 5 and the mounting platform 1 is not very large during the adjustment of the movement of the mounting platform 1. Through making spacing post 13 under the conventional condition be located recess 51 center, when removing adjustment mounting platform 1, mounting platform 1 can both satisfy mounting platform 1's removal demand in the distance that can supply to remove in arbitrary one orientation, and the design is more reasonable.

Preferably, the elastic member 52 may be a spring, an elastic rubber pad, or the like.

In an embodiment, the bottom of the limiting column 13 is provided with a limiting disc 14, the diameter of the limiting disc 14 is larger than the diameter of the corresponding groove 51, and a limiting groove 53 for the limiting disc 14 to move in the horizontal direction is formed at the position of the supporting leg 5 corresponding to the limiting disc 14. By the design, the landing legs can be prevented from being separated from the mounting platform by the aid of the design of the limiting disc, assembling difficulty between the mounting platform and the landing legs is reduced, and the limiting column can be kept to normally work by arranging the limiting groove.

Preferably, each support leg 5 has an independent lifting function, and is used for driving each part of the corresponding mounting platform 1 to lift. It should be noted that the support legs with lifting function are common knowledge of those skilled in the art, and for example, the outer temporary support legs used in the excavator may be replaced by hydraulic telescopic parts in the prior art.

In the concrete implementation, because the ground below the electric power tower is mostly uneven, the landing leg with independent lifting function is convenient for leveling the mounting platform, so that the equipment can be applied to various terrains.

In an embodiment, the base rod 2 is provided with a reference slot 21, a reference inserting rod 43 is provided on the clasping component corresponding to the reference slot 21, the reference inserting rod 43 is used for being inserted into the reference slot 21, and two sides of the reference inserting rod 43 are attached to the reference slot 21 and can slide up and down in the reference slot 21.

In a specific implementation, since the clasping assembly is fixed on the mounting platform 1, the reference inserting rod 43 and the reference inserting groove 21 can be inserted to determine the angle of the mounting platform 1 relative to the base rod 2. The angle of the tower 8 relative to the mounting platform 1 can be fixed such that the tower 8 is indirectly aligned with the angle of the base pole 2 through the mounting platform 1. Thus, the screw hole of the tower column 8 on the mounting platform 1 is not easy to be dislocated with the screw hole on the base rod 2. Compared with the mode of aligning the screw holes in the original patent, the mode of aligning is simple and quick, and the consumed time is less. Compared with the traditional scribing alignment mode, the angle of the mounting platform 1 relative to the base rod 2 is easier to determine and simpler to operate.

The reference inserting rod 43 can slide up and down in the reference inserting groove 21, so that the leveling of the mounting platform 1 is facilitated, and the influence on the leveling of the mounting platform 1 caused by the matching of the reference inserting groove 21 and the reference inserting rod 43 is avoided.

Of course, the positions of the reference slot 21 and the reference plunger 43 may be interchanged, i.e. the reference slot 21 is provided on the clasping assembly and the reference plunger 43 is provided on the base pole 2. Both of these modes work the same.

Preferably, the datum bar 43 is provided on the push plate 42 of the corresponding clasping assembly. By the design, the structure is reasonable, and the reference inserting rod 43 and the reference inserting groove 21 are convenient to insert and separate.

In one embodiment, the fan blade mounting device 9 is arranged on the mounting platform 1, and the fan blade mounting device 9 is positioned on one side of the mounting tower 6 and used for mounting fan blades to a fan at the top end of the tower column 8.

In a specific implementation, the fan at the top end of the tower column can be installed when the top end of the tower column exceeds the top of the installation tower, as described in patent application No. 202210050903.5, entitled an offshore fan installation device, and since the technology of the fan blade installation device is disclosed, it is not described herein in detail. However, it should be noted that, due to the arrangement of the fan blade mounting device, the distance between the mounting tower and the fan blade mounting device is too small, and the lower first telescopic component cannot be mounted, so that the first telescopic component is arranged below the mounting tower, and the interference between the first telescopic component and the fan blade mounting device is avoided. Meanwhile, in order to reduce the height of the mounting platform and ensure that the first telescopic part has enough elongation, a multi-section telescopic hydraulic telescopic cylinder is particularly used as the first telescopic part.

s1, moving the installation platform 1 to enable the reference inserting rod 43 to be inserted into the reference inserting groove 21, and determining the angle of the installation platform 1 relative to the base rod 2 by taking the reference inserting rod as a reference;

s2, leveling the mounting platform 1, and enabling the clamping component to clamp the base rod 2 tightly;

s3, moving the supporting platform 3, and conveying the tower column 8 to the docking station 15;

s4, completing splicing and combining of the tower column 8, the fan and the fan blades under the matching of the mounting tower 6, the limiting device, the first telescopic part 7 and the fan blade mounting device 9;

and S5, removing the supporting platform 3, then driving the combined tower column 8 to move downwards under the driving of the first telescopic part 7, and butting the combined tower column with the base rod 2 in the butting station 15 to complete the installation of the electric power tower.

In specific implementation, the insertion of the reference insertion rod 43 and the reference insertion slot 21 can be used to determine the angle of the installation platform 1 relative to the base rod 2, so that the installation platform 1 uses the base rod 2 as a reference, and the tower column 8 uses the installation platform 1 as a reference, so that the tower column 8 and the base rod 2 can be unified under the same coordinate system (that is, the coordinate system using the base rod 2 as a reference), and when the angle of the installation platform 1 relative to the base rod 2 is determined, the angle of the tower column 8 aligns with the angle of the base rod 2, so that a screw hole of the tower column 8 on the installation platform 1 is not easy to be misaligned with a screw hole on the base rod 2. Through hugging closely the subassembly with base pole 2 hug closely, the reaction force of hugging closely on the subassembly can promote mounting platform 1 and remove, makes base pole 2 be in the central point department of butt joint station 15. Compared with the alignment mode in the original patent, the alignment device has the advantages of relatively simple structure and relatively simple operation process.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
