Description

Technical Field

[0001] This utility model relates to the field of power generation equipment construction and installation technology, specifically to a verticality correction device for a concrete tower of a wind turbine generator set. Background Technology

[0002] The construction of large-scale wind turbine generators has become a trend in new energy development, especially the construction of large-scale onshore wind turbine generators. This is beneficial for increasing the proportion of renewable energy, optimizing the local power supply system structure, and reducing local power supply pressure. In recent years, steel-concrete hybrid wind turbine generator towers have been widely used. They have the advantages of convenient manufacturing, fast construction, stable structure, and low construction cost. Most importantly, this structure can increase the height of the wind turbine hub to 120m and above, which can better utilize wind resources. The precast prestressed segmented concrete tower installation construction method has been widely adopted, which has the advantages of short construction period, controllable quality, and low cost.

[0003] Currently, the installation of segmented concrete towers requires the tower body to be hoisted and adjacent sections to be installed. However, during the hoisting process, steel cables are often used directly for hoisting and fixing. If a tilt occurs on one side during hoisting or alignment, it is difficult to correct, increasing transportation risks and installation difficulty. Construction personnel need to be below the tower to direct the crane to adjust its direction, resulting in low construction efficiency and safety hazards.

[0004] Therefore, there is an urgent need for a verticality correction device for the concrete tower of a wind turbine generator to solve the problem of inconvenience in correction when the tower body tilts on one side. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing a verticality correction device for the concrete tower of a wind turbine generator set, thereby solving the problem of inconvenient correction when a certain side of the tower body tilts.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A verticality correction device for a concrete tower of a wind turbine generator includes a support rod, a bracket, a support ring, a support sleeve, a drive adjustment assembly, several push rods, and a telescopic assembly. The support ring has a centrally located support rod vertically fixed to its inner side via several brackets. The upper end of the support rod is used to connect to external hoisting equipment. A coaxial support sleeve is rotatably fitted onto the outer side of the upper end of the support ring. The upper end of the support sleeve has an upwardly protruding arc-shaped protrusion. The inner diameter of the support sleeve is larger than the inner diameter of the support ring. Several push rods are equidistantly arrayed on the upper end of the support sleeve, with one end of each push rod slidably against the upper end of the support sleeve, and the other end extending towards the inner side of the support ring and connected to a steel cable. The push rods are mounted vertically on the upper end of the support ring located inside the support sleeve via the telescopic assembly. The steel cable passes through the gaps in the brackets and hangs downwards, connecting to an installation cylinder. The drive adjustment assembly is mounted on the bracket and drives the support sleeve to rotate, carrying the protrusion.

[0008] To optimize the above technical solution, the specific measures also include:

[0009] Furthermore, the drive adjustment assembly includes an internal gear ring, a drive motor, and a gear. An internal gear ring is provided on the inner side of the support sleeve. The drive motor is mounted on the bracket, and the output end of the drive motor is connected to a gear. The gear meshes with the internal gear ring, and the drive motor is used to drive the gear to rotate and drive the internal gear ring to rotate with the support sleeve.

[0010] Furthermore, the telescopic assembly includes a telescopic rod and a crossbar. The upper end of the support ring located inside the support sleeve is fixedly connected to a vertically arranged telescopic rod. The telescopic rod is slidably connected to a vertically arranged crossbar inside. The top of the crossbar is fixedly connected to a push rod.

[0011] Furthermore, the outer upper end of the support ring is movably connected to the inner lower end of the support sleeve via a bearing.

[0012] Furthermore, an auxiliary ring is provided on the inner side of the support ring, through which the steel cable can pass.

[0013] Furthermore, it also includes a disc, the lower end of the support rod extends to the bottom of the support ring, and a disc coaxial with the support ring is fixedly connected by several connecting rods, and an auxiliary ring is provided on the inner side of the disc for the steel cable to pass through.

[0014] Furthermore, the auxiliary ring on the inner side of the support ring is vertically aligned with the auxiliary ring on the inner side of the disk.

[0015] Furthermore, it also includes a support shell, which is used to snap onto the top of the mounting cylinder, and the support shell is equipped with a level.

[0016] Furthermore, a screw is threaded through the side of the support shell, and a knob is fixedly connected to one end of the screw away from the support shell. The other end of the screw can be moved to abut against the side wall of the mounting cylinder.

[0017] Furthermore, the upper end of the support rod is provided with a traction ring for connecting external lifting equipment.

[0018] The beneficial effects of this utility model are:

[0019] This invention, through the configuration of support rods, brackets, support rings, support sleeves, drive adjustment components, several push rods, and telescopic components, can be used in conjunction with external hoisting equipment to lift the installation cylinder and transport it above the base cylinder for subsequent installation. Furthermore, if tilting occurs on one side during the hoisting process or when the installation cylinder is aligned with the base cylinder, the drive adjustment components can be used to drive the support sleeve to rotate, and the ramp of the protrusion will push the push rod on that side, which is attached to the upper end of the support sleeve, upwards. This, in turn, lifts and tightens the steel cable attached to the push rod on that side, allowing for quick and convenient adjustment of the vertical angle of the installation cylinder. This solves the problem of inconvenient correction and effectively improves the transportation safety of the installation cylinder and the installation efficiency of the concrete tower.

Detailed Implementation

[0026] The present invention will now be described in detail with reference to the accompanying drawings.

[0027] As attached Figure 1 and attached Figure 2 As shown in the figure, a verticality correction device for a concrete tower of a wind turbine generator according to an embodiment of the present invention includes a support rod 4, a bracket 6, a support ring 7, a support sleeve 8, a drive adjustment assembly, several push rods 11, and a telescopic assembly. The support rod 4, located at the center, is vertically fixed to the inner side of the support ring 7 via several brackets 6. The upper end of the support rod 4 is used to connect external lifting equipment. A coaxial support sleeve 8 is rotatably fitted on the outer side of the upper end of the support ring 7. The upper end of the support sleeve 8 has an upwardly protruding arc-shaped protrusion 9. The inner diameter of sleeve 8 is larger than the inner diameter of support ring 7. Several push rods 11 are arranged in an equidistant array on the upper end of support sleeve 8, and one end of each push rod 11 can slide against the upper end of support sleeve 8, while the other end extends to the inner side of support ring 7 and is connected to steel cable 5. The middle part of push rod 11 is installed on the upper end of support ring 7 located inside support sleeve 8 through telescopic component. Steel cable 5 passes through the gap of bracket 6 and hangs down to connect to mounting cylinder 1. Drive adjustment component is installed on bracket 6 and is used to drive support sleeve 8 to rotate with protrusion 9.

[0028] This utility model, through the configuration of support rod 4, bracket 6, support ring 7, support sleeve 8, drive adjustment component, several push rods 11, and telescopic component, can cooperate with external hoisting equipment to lift the installation cylinder 1 and transport it above the bottom cylinder 20 for subsequent installation. When the installation cylinder 1 is being hoisted or aligned with the bottom cylinder 20, if a tilt occurs on one side, the drive adjustment component can be used to drive the support sleeve 8 to rotate with the protrusion 9. The slope of the protrusion 9 will push the push rod 11 attached to the upper end of the support sleeve 8 on that side to move upward, thereby driving the push rod 11 on that side to lift and tighten the steel cable 5, so as to quickly and conveniently adjust the vertical angle of the installation cylinder 1, solving the problem of inconvenient correction, and effectively improving the transportation safety of the installation cylinder 1 and the installation efficiency of the concrete tower.

[0029] As attached Figure 4 As shown, specifically, the surface of the protrusion 9 is in contact with one end of the push rod 11. The push rod 11 can slide along the arc surface of the protrusion 9 when the support sleeve 8 rotates, thereby adjusting the height of the push rod 11 and raising or lowering the steel cable 5.

[0030] In this design, the support ring 7 and the support rod 4 can be further reinforced by an additional bracket. The steel cable 5 and the mounting cylinder 1 can be connected by a structure such as a locking buckle, which can be installed on the top of the mounting cylinder 1.

[0031] In another specific embodiment based on the above, the drive adjustment assembly includes an internal gear ring 12, a drive motor 10, and a gear 13. An internal gear ring 12 is provided on the inner side of the support sleeve 8. The drive motor 10 is mounted on the bracket 6, and the output end of the drive motor 10 is connected to the gear 13. The gear 13 meshes with the internal gear ring 12. The drive motor 10 drives the gear 13 to rotate, thereby causing the internal gear ring 12 to rotate along with the support sleeve 8. This facilitates stable driving of the support sleeve 8.

[0032] As attached Figure 3 As shown, in another specific embodiment based on the above, the telescopic assembly includes a telescopic rod 14 and a crossbar 15. The upper end of the support ring 7, located inside the support sleeve 8, is fixedly connected to the vertically arranged telescopic rod 14. The telescopic rod 14 is slidably connected to the vertically arranged crossbar 15, and the top of the crossbar 15 is fixedly connected to the push rod 11. Thus, the vertical position of the push rod 11 can be limited by the arrangement of the telescopic rod 14 and the crossbar 15.

[0033] In another specific embodiment based on the above, the upper outer side of the support ring 7 is movably connected to the lower inner side of the support sleeve 8 via a bearing.

[0034] In another specific embodiment based on the above, an auxiliary ring 17 is also provided on the inner side of the support ring 7, through which the steel cable 5 can pass.

[0035] As attached Figure 5 As shown, in a further embodiment based on the above, a disc 16 is also included. The lower end of the support rod 4 extends below the support ring 7 and is fixedly connected to the disc 16, which is coaxial with the support ring 7, by several connecting rods 18. An auxiliary ring 17 is provided on the inner side of the disc 16 for the steel cable 5 to pass through. In this way, the stability of the steel cable 5 in use can be increased by setting the disc 16 and the auxiliary ring 17.

[0036] The auxiliary ring 17 inside the support ring 7 is vertically aligned with the auxiliary ring 17 inside the disc 16. This further increases the stability of the steel cable 5 during use.

[0037] In another specific embodiment based on the above, a support shell 2 is also included. The support shell 2 is used to snap onto the top of the mounting cylinder 1, and a level 3 is provided on the support shell 2. In this solution, the level 3 can be equipped with a tilt sensor and an angle measurement function. Through these additional devices, the angle value that can indicate the tilt degree of the mounting cylinder 1, such as the angle with the vertical line, can be conveniently measured, so that the operator can directly obtain the tilt angle of the mounting cylinder 1 and thus determine whether the mounting cylinder 1 meets the design vertical requirements.

[0038] The support shell 2 has a threaded connection to a screw 21 running through its side. A knob is fixedly connected to one end of the screw 21 away from the support shell 2, and the other end of the screw 21 can be moved to abut against the side wall of the mounting cylinder 1. This facilitates the assembly and disassembly of the support shell 2.

[0039] In another specific embodiment based on the above, the upper end of the support rod 4 is provided with a traction ring 19 for connecting external lifting equipment. This facilitates connecting the support rod 4 to external lifting equipment.

[0040] One specific embodiment of this utility model is as follows:

[0041] The number of push rods 11 and steel cables 5 are provided in four sets, which are equally spaced. The top four corners of the installation cylinder 1 are provided with locking structures. When in use, after the staff installs the support shell 2 to the top of the installation cylinder 1 and connects the steel cables 5, the traction ring 19 can be used to connect with the external lifting equipment. The device and the installation cylinder 1 can be lifted by the lifting equipment. During the movement of the installation cylinder 1 or when it is aligned with the bottom cylinder 20, the verticality of the installation cylinder 1 can be checked by the level 3.

[0042] When a tilt is detected on one side of the installation cylinder, the drive motor 10 can be started by an external controller. The drive motor 10, in conjunction with the gear 13, drives the internal gear ring 12 to rotate. The internal gear ring 12, in conjunction with the support sleeve 8, drives the protrusion 9 to rotate. The protrusion 9 pushes the push rod 11 to move upward, lifting the steel cable 5, thereby hoisting the downward tilted side of the installation cylinder 1 upward. This allows for quick and convenient adjustment of the vertical angle of the installation cylinder 1. During the movement of the push rod 11, the crossbar 15 is slidably connected to the inner wall of the telescopic rod 14, which can maintain the vertical movement of the push rod 11 after it is pushed. The steel cable 5 passes through the upper and lower sets of auxiliary rings 17, which can be used to support the movement of the steel cable 5 and ensure the stability of the adjustment.

[0043] Specifically, the protrusion 9 can rotate 360 ​​degrees with the support sleeve 8. The protrusion 9 can pass through the bottom of the four sets of push rods 11 to adjust the four corners of the installation cylinder 1 individually, ensuring the adjustment of the tilt state of the installation cylinder 1, which facilitates the increase of safety during transportation, facilitates alignment and installation with the bottom cylinder 20, and effectively improves the installation efficiency of the concrete tower cylinder.
