Description

Technical Field

[0001] This utility model relates to the field of concrete tower technology, specifically to a concrete tower segment splicing device. Background Technology

[0002] Concrete wind turbine towers are assembled from a large number of precast concrete components, which can be cylindrical, circular, rectangular, or other shapes. They are then assembled into a cylindrical structure of the required specifications for the wind power project and anchored to the foundation to support the entire wind turbine. During on-site construction, the concrete tower segments are pre-assembled into tower sections using splicing equipment before being hoisted.

[0003] Chinese patent CN114046227A discloses a concrete tower segment splicing device. It uses a clamping component set on a support beam to clamp and fix the segments. An adjustment component that drives the clamping component to move in the horizontal plane realizes automatic adjustment of the segment position. This reduces the segment position deviation caused by hoisting or other external factors, improves the accuracy of subsequent segment splicing, and eliminates the need for manual pushing, thus improving splicing efficiency.

[0004] The above solution uses clamping and adjusting components to adjust the position of the tube segments fixed on the clamping components. However, since each clamping component is adjusted using different adjusting components, it is difficult to accurately position the tube segments spliced ​​by the clamping components, resulting in splicing errors and affecting the installation quality of the tower.

[0005] Therefore, this utility model provides a concrete tower segment splicing device to solve the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, this utility model provides a concrete tower segment splicing device to solve the problem that the segments spliced ​​by the clamping components are difficult to be accurately positioned due to the fact that each clamping component is adjusted by different adjustment components, resulting in splicing errors and affecting the quality of tower installation.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A concrete tower segment splicing device includes a first support, a rotating shaft rotatably connected to the first support, a rotating component for rotating the rotating shaft on the first support, a fixed platform fixedly connected to the rotating shaft, and an adjusting seat arranged in a circular array fixedly connected to the fixed platform. Each adjusting seat has a groove, and a slider is slidably connected in each groove. The slider is provided with a clamping component for clamping the segment and a supporting component for supporting the segment.

[0009] A second support is fixedly connected to the fixed platform, and a second motor is installed on the fixed platform. A screw is installed on the output shaft of the second motor, and a lifting block is threaded onto the screw. A series of hinged rods arranged in a circular array are hinged onto the lifting block, and one end of each hinged rod is hinged to a slider.

[0010] Preferably, a chassis is fixedly connected to the first support, and the bottom surface of the adjusting seat is rotatably connected to rollers arranged at equal intervals, with the bottom ends of the rollers abutting against the chassis.

[0011] Preferably, the rotating assembly includes a first motor mounted on a first support, and bevel gears are fixedly connected to both the output shaft of the first motor and the rotating shaft, with the two bevel gears meshing with each other.

[0012] Preferably, the clamping assembly includes a clamping seat fixedly connected to the slider, the clamping seat having a clamping groove, an adjusting screw threadedly connected to the clamping seat, one end of the adjusting screw being fixedly connected to a clamping plate, and the clamping plate being located within the clamping groove.

[0013] Preferably, the support assembly includes a fixed rod fixedly connected to the slider, the fixed rod having a rotating groove, a rotating rod rotatably connected within the rotating groove, and a stop rod fixedly connected to the rotating rod.

[0014] Preferably, the support assembly further includes an electric push rod mounted on a fixed rod, one end of the rotating rod passing through a rotating groove and fixedly connected to a transmission gear, and the telescopic end of the electric push rod being fixedly connected to a rack, which meshes with the transmission gear.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. Through the coordinated arrangement of the rotating shaft, fixed platform, rotating assembly, and clamping assembly, the rotating assembly drives the fixed platform to rotate, which can flexibly adapt to the initial position deviation of the hoisted segments. Meanwhile, the screw driven by the second motor moves, and the hinged rod mechanism can synchronously control the movement of multiple sliders, ensuring that all clamping components are adjusted synchronously. This avoids the cumulative error caused by traditional independent adjustment, significantly improves the splicing accuracy of the segments, reduces manual intervention, and improves construction efficiency.

[0017] 2. Through the coordinated arrangement of clamping and support components, the clamping slot and adjustable clamping plate achieve a firm clamping of the tube segment, while the electric push rod driven abutment rod can dynamically adjust the support angle to further stabilize the tube segment. The design of the roller and chassis distributes the force on the adjustment seat and ensures the stability during rotation. Attached Figure Description

[0023] The following will refer to the attached reference. Figures 1 to 4 The various embodiments of this utility model will be described in detail below. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this utility model and are not intended to limit the scope of protection of this utility model.

[0024] A concrete tower segment splicing device includes a first support 1, a rotating shaft 2 rotatably connected to the first support 1, the top end of the rotating shaft 2 passing through the first support 1 and extending above the first support 1, and a rotating assembly for rotating the rotating shaft 2 is provided on the first support 1. The rotating assembly includes a first motor 3 installed on the first support 1, and bevel gears 4 are fixedly connected to both the output shaft of the first motor 3 and the rotating shaft 2, and the two bevel gears 4 mesh with each other.

[0025] When it is necessary to drive the rotating shaft 2 to rotate, the output shaft of the first motor 3 drives the rotating shaft 2 to rotate through two bevel gears 4.

[0026] Among them, a fixed platform 6 is fixedly connected to the rotating shaft 2, and an adjustment seat 7 arranged in a circular array is fixedly connected to the fixed platform 6. A chassis 5 is fixedly connected to the first support 1. Rollers 15 arranged at equal intervals are rotatably connected to the bottom surface of the adjustment seat 7, and the bottom end of the roller 15 abuts against the chassis 5.

[0027] Since the fixed platform 6 is installed on the rotating shaft 2, when the rotating shaft 2 rotates, it can drive the fixed platform 6 to rotate synchronously, thereby fine-tuning the position of the adjusting seat 7 to adapt to the concrete segments lifted by the crane. Moreover, the adjusting seat 7 will drive the roller 15 to roll on the chassis 5, and the roller 15 will provide auxiliary support for the adjusting seat 7.

[0028] In this embodiment, each adjusting seat 7 is provided with a sliding groove 8, and a slider 9 is slidably connected in each sliding groove 8. The slider 9 is provided with a clamping component for clamping the pipe segment and a support component for supporting the pipe segment.

[0029] The clamping assembly includes a clamping seat 16 fixedly connected to the slider 9. The clamping seat 16 has a clamping groove 17. An adjusting screw 18 is threadedly connected to the clamping seat 16. One end of the adjusting screw 18 is fixedly connected to a clamping plate 19, and the clamping plate 19 is located in the clamping groove 17.

[0030] When the slider 9 moves within the slide groove 8, it will drive the clamping assembly to move synchronously. After the bottom end of the tube is placed inside the clamping groove 17, the clamping plate 19 is fixed against the tube by rotating the adjusting screw 18.

[0031] The support assembly includes a fixed rod 20 fixedly connected to the slider 9, a rotating groove 21 is provided on the fixed rod 20, a rotating rod 22 is rotatably connected in the rotating groove 21, and an abutment rod 23 is fixedly connected to the rotating rod 22.

[0032] The rod-shaped structure formed by the abutment rod 23 and the fixing rod 20 provides auxiliary support for the pipe segments fixed in the clamping groove 17.

[0033] In this embodiment, the support assembly also includes an electric push rod 25 mounted on the fixed rod 20. One end of the rotating rod 22 passes through the rotating groove 21 and is fixedly connected to a transmission gear 24. The telescopic end of the electric push rod 25 is fixedly connected to a rack 26, and the rack 26 meshes with the transmission gear 24.

[0034] The extension end of the electric push rod 25 drives the rack 26 to move up and down, and the rack 26 meshes with the transmission gear 24 to drive the rotating rod 22 to swing the abutment rod 23, and abut one end of the abutment rod 23 against the tube segment to support it.

[0035] A second support 10 is fixedly connected to the fixed platform 6. A second motor 11 is installed on the fixed platform 6. A screw 12 is installed on the output shaft of the second motor 11. A lifting block 13 is threadedly connected to the screw 12. A series of hinge rods 14 arranged in a circular array are hinged to the lifting block 13, and one end of the hinge rods 14 is hinged to the slider 9.

[0036] When the positions of multiple sliders 9 in the slide groove 8 are adjusted synchronously, the output shaft of the second motor 11 drives the screw 12 to rotate and the lifting block 13 to move up and down. Under the action of the hinge rod 14, the multiple sliders 9 move synchronously in different slide grooves 8 respectively, so as to make targeted adjustments according to the size of different tube segments. Moreover, when there is a deviation in the unloading position of the crane, the position of the clamping component can be adjusted by rotating the fixed platform 6.
