DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Now, the present invention will be further described in detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so they only show the components related to the present invention.

[0022] Please refer to Figures 1-4, a rolling storage device for wind power tower barrels, comprising the tower barrel 100 to be stored and a plurality of parallel slide beams 5. Two driving rollers 1 or driven rollers 2 are respectively arranged on each slide beam 5. A connecting piece 7 is arranged on one side of the slide beam 5, and a movable joint 11 is arranged on the other side. The plurality of slide beams 5 are spliced and matched through the connecting piece 7 and the movable joint 11. The connecting piece 7 and the movable joint 11 are detachably connected by a spring pin 10.

[0023] As Figure 2 shown, two driving rollers 1 or driven rollers 2 are respectively arranged on each slide beam 5, and the driving rollers 1 and the driven rollers 2 are arranged adjacent to each other; in this embodiment, the driving rollers 1 and the slide beam 5 can be understood as a driving wheel module, and the driven rollers 2 and the slide beam 5 can be understood as a driven wheel module. When in use, the driving wheel module and the driven wheel module are plugged and matched through the connecting piece 7; after matching, the driving wheel module and the driven wheel module form a set of storage devices.

[0024] Please refer to Figure 1 again, the tower barrel 100 is supported and stored by at least two sets of storage devices; after storage, the driving rollers 1 are active, so that the tower barrels stored above and the driven rollers rotate accordingly.

[0025] In this embodiment, the connecting piece 7 is a steel sleeve, and the connecting piece 7 can be nested with the movable joint. After nesting, it is released by the spring pin 10 to achieve the connection purpose.

[0026] Among them, a support structure is further arranged at the middle of the slide beam 5. The support mechanism includes a reinforcing plate 9 and reinforcing ribs 91. The reinforcing ribs 91 are welded and fixed on both sides of the middle of the slide beam 5. The reinforcing plate 9 is welded at the bottom of the reinforcing ribs 91. The reinforcing plate 9 and the reinforcing ribs 91 are in an inverted T shape. Such a setting can greatly improve the support strength of the middle part of the slide beam. When in use, the reinforcing plate 9 plays a supporting role, and its bottom is in contact with the ground.

[0027] Specifically, both the driving rollers 1 and the driven rollers 2 are arranged on a sliding base 8. A chute 51 is arranged on the surface of the slide beam 5 along its own length direction. A slider matching with the chute 51 is arranged on the bottom surface of the sliding base 8. The distance between every two driving rollers 1 and the driven rollers 2 can be adjusted through the sliding base 8 so as to meet tower barrels of different sizes and specifications. A locking bolt penetrating upward is arranged at the bottom of the slide beam 5, and the locking bolt extends vertically downward to the bottom of the sliding base 8.

[0028] That is to say, both the driving roller 1 and the driven roller 2 can move on the slideway beam 5 through the sliding base 8, so as to adjust the distance between the driving rollers and between the driven rollers to meet the tower barrels with different outer diameters; after the sliding base 8 moves to the required position, turn the locking bolt at the bottom of the slideway beam 5 to make the locking bolt extend into the corresponding sliding base 8, so as to lock the position of the rollers.

[0029] In this embodiment, a plurality of locking holes for cooperating with the locking bolts are provided at the bottom of the sliding base 8 to meet the locking at different positions.

[0030] In this embodiment, the two driving rollers 1 are arranged on the same slideway beam 5. During specific installation and use, the two driving rollers 1 can also be arranged at diagonal positions to disperse the power and improve the rotation effect of the tower barrel.

[0031] One side of the driving roller 1 is provided with a power system 3. The power system 3 is fixed on the sliding base 8. The power system 3 can move along with the driving roller 1. A power transmission device 4 connecting the driving roller 1 is provided at the output end of the power system 3; the power system 3 is a driving motor, and the power transmission device 4 is a gear transmission group. The gear transmission group includes two mutually cooperating gears. One gear is in transmission connection with the motor, and the other is in transmission connection with the driving roller 1. When the driving motor runs, the driving roller 1 is driven to rotate through the gear transmission group, and the purpose of the tower barrel rolling is achieved through power transmission.

[0032] In order to further improve the stable support and rotation of the tower barrel 100, a connecting plate 6 is further provided outside the driving roller 1. The connecting plate 6 is fixed on the surfaces of the two movable joints 11. The two sides of the connecting plate 6 are horizontally penetrated with safety bolts 61. A plurality of connecting holes 81 are provided outside the sliding base 8. The safety bolts 61 penetrate through the connecting plate 6 and extend into one of the connecting holes 81.

[0033] During use, after the sliding base 8 moves to the required position, first turn the locking bolt at the bottom of the slideway beam 5 to make the locking bolt extend into the corresponding sliding base 8, so as to initially lock the positions of the driving and driven rollers; after the initial locking, turn the safety bolt 61 to make the safety bolt 61 extend into one of the connecting holes 81; at this time, the locking bolt is vertically locked and the safety bolt 61 is horizontally locked. When any one of the locking bolts or safety bolts fails and breaks, the others can also play a limiting and insurance role to prevent the tower barrel from failing to rotate.

[0034] Based on the above embodiments, the storage device of the present application can also be extended and spliced according to the length, outer diameter, mass, etc. of the tower barrel 100; for details, please refer to Figure 5 .

[0035] During use, since the connecting piece 7 and the movable joint 11 can be inserted and matched, when it is difficult for the two sets of devices at both ends to drive the tower barrel 100 to rotate, additional splicing and storage devices can be installed to improve the overall driving ability and load-bearing capacity.

[0036] The present invention also discloses a method for using a rolling storage device for a wind power tower barrel, including the following steps: S1: Install the main rolling wheels and the slave rolling wheels according to the diameter of the tower barrel to be carried, and adjust the distance between the two main rolling wheels and the slave rolling wheels through the slideway beam and the sliding base; S2: Install the power system, the power transmission device and the connecting plate, and after the installation is completed, conduct a power-on test run to check the rotation direction and speed of the main rolling wheels; S3: Use the connecting piece and the movable joint for splicing and nesting. After the nesting is completed, release the spring pin, and use the main rolling wheels and the slave rolling wheels to splice and connect the two modules into a whole; S4: Level and tamp the storage site of the tower barrel, mark the storage positions of the storage devices at both ends of the tower barrel on the ground, and hoist the storage devices to the predetermined support positions; S5: Hoist the tower barrel so that the circumferences at both ends of the tower barrel are respectively in contact with the active rollers and the driven rollers; S6: Conduct a test run after the tower barrel is placed in place to ensure that the tower barrel rotates in the axial direction.

[0037] In the step S1, bolts are passed through the bottom holes of the sliding base and tightened into the slideway beam to fix the distance between the two rolling wheels.

[0038] Preferably, in the step S4, after the storage device is hoisted to the predetermined support position, ensure that the reinforcing plate is in close contact with the ground.

[0039] Obviously, the above embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
