Description

Technical Field

[0001] This invention relates to the field of wind power construction technology, and more specifically, to a modular steel cage tooling for concrete tower segments. Background Technology

[0002] With the development of the wind power industry, high-power wind turbine generators are becoming increasingly common, and their tower heights are also increasing. Steel-concrete composite towers have gained widespread use due to their excellent rigidity and economy. Concrete towers are typically produced by prefabricating sections in a factory and then assembling them on-site. These concrete segments are frustum-shaped, meaning they have different diameters at the top and bottom, and the taper and diameter also vary between segments of different heights.

[0003] In the prefabrication of tunnel segments, tying the reinforcing cage is a crucial step. Traditional reinforcing cage fixtures are mostly fixed, integrally welded frames, with dimensions such as curvature and width corresponding one-to-one with specific tunnel segments. However, the diverse specifications of tunnel segments in mixed-tower construction necessitate the production of numerous fixed fixtures of varying sizes. This not only results in significant fixture manufacturing costs but also occupies substantial factory storage and production space, making management and changeover scheduling extremely inconvenient.

[0004] To overcome the shortcomings of fixed tooling, some adjustable tooling solutions have emerged in the prior art. However, their adjustable dimensions are graded and discontinuous, and they cover a small range of design specifications, thus limiting their flexibility. More importantly, the adjustment process usually requires the disassembly and reinstallation of a large number of bolts and beams, which is cumbersome, time-consuming, and hinders rapid changeover, affecting production efficiency. In view of this, we propose a modular steel cage tooling for concrete tower segments. Summary of the Invention

The housing is fixedly connected to the gear. The slot is annularly and equally spaced on the outer wall of the housing. The inner cylinder is fixedly disposed inside the housing. The magnetic drive component is disposed inside the inner cylinder. The variable gear component is annularly and equally spaced on the outer wall of the inner cylinder. The end of the variable gear component away from the inner cylinder is movably inserted into the slot.

[0011] Preferably, the magnetic drive component includes a magnetic block body, which is inserted into the inner cylinder. The magnetic block body has a multi-prism structure and several outer wall surfaces evenly distributed along the circumference.

[0036] like Figures 1 to 16 As shown, the present invention relates to a modular steel cage fixture for concrete tower segments, comprising a fixture platform 1; a first pitch mechanism 2 disposed on the fixture platform 1 for adjusting the length of the fixture; a second pitch mechanism 3 disposed on the first pitch mechanism 2 for adjusting the width of the fixture; a binding frame 4 disposed on the second pitch mechanism 3; two modular arc plate mechanisms 5 symmetrically disposed at the top of the binding frame 4; and a plurality of crossbars 6 detachably connected between the two modular arc plate mechanisms 5. The modular arc plate mechanism 5 includes an arc plate assembly 501, a rotating assembly 502, a moving assembly 503, and a clamp 504. The arc plate assembly 501 is symmetrically arranged at the top of the binding frame 4. The rotating assembly 502 is arranged in an arc shape with equal intervals inside the arc plate assembly 501. The moving assembly 503 is movably arranged in an arc shape with equal intervals inside the arc plate assembly 501. The rotating assembly 502 and the moving assembly 503 are meshed and connected. The clamp 504 is fixedly arranged at the end of the moving assembly 503 away from the rotating assembly 502. The clamp 504 is detachably connected to the cross frame 6. The rotating component 502 has a curvature adjustment state and a radius adjustment state; in the radius adjustment state, the driving moving component 503 moves synchronously to adjust the radius of the supporting arc surface formed by the crossbeam 6; in the curvature adjustment state, the driving moving component 503 moves asynchronously to adjust the curvature of the supporting arc surface formed by the crossbeam 6.

[0037] Among them, the first pitch-changing mechanism 2 and the second pitch-changing mechanism 3 are existing technologies in this field, and therefore will not be described in detail here; secondly, as Figure 3 and Figure 4 As shown, the four connecting rods of the binding frame 4 in this invention are mutually movable and can be freely extended and retracted, thereby adapting to the length changes of the first pitch mechanism 2 and the second pitch mechanism 3.

[0038] In this invention, when it is necessary to tie steel cages of different specifications for concrete tower segments, firstly, the first pitch mechanism 2 is operated to adjust the overall length of the entire tooling, and at the same time, the second pitch mechanism 3 is operated to adjust the overall width of the entire tooling, so as to achieve preliminary adaptation of the macroscopic dimensions of the steel cage.

[0039] Subsequently, the rotating component 502 is controlled to operate in the radius adjustment state. In this state, the rotating component 502 drives all moving components 503 to move synchronously. Since each moving component 503 is connected to the crossbeam 6 through the clamp 504, their synchronous movement will cause the support arc surface formed by all the crossbeams 6 to expand or shrink as a whole, thereby adjusting the radius of the support arc surface in one go to match the radius of the target segment.

[0040] Alternatively, the rotating component 502 can be switched to curvature adjustment mode. In this mode, the rotating component 502 drives the individual moving components 503 to move asynchronously. This allows the crossbeams 6 at different positions to generate different amounts of displacement, thereby changing the degree of curvature of the supporting arc surface at different positions, i.e., adjusting its curvature to precisely match the taper requirements of the tube segments.

[0041] Through the coordinated adjustment of the length, width, radius and curvature, the tooling can be quickly configured into an ideal form suitable for binding steel cages of specific specifications of pipe segments, effectively solving the technical problems of poor versatility and cumbersome changeover of traditional tooling.

[0042] In an embodiment of the present invention, the arc plate assembly 501 includes a plate body 5011, a shell 5012, insert strips 5013 and elongated holes 5014. The plate body 5011 is movably inserted into the top of the binding frame 4 through the insert strips 5013 at both ends. The shell 5012 is connected to the plate body 5011. The elongated holes 5014 are opened in an arc shape at equal intervals on the plate body 5011. The rotating assembly 502 is arranged in an arc shape at equal intervals on the plate body 5011 near the elongated holes 5014. The moving assembly 503 is movably inserted into the elongated holes 5014.

[0043] In an embodiment of the present invention, the rotating assembly 502 includes a gear 5021, a synchronous belt 5022, a servo motor 5023, and a magnetic drive gear variable unit 505. The gear 5021 is rotatably mounted on the plate 5011 near the elongated hole 5014 in an arc shape with equal intervals. The magnetic drive gear variable unit 505 is fixedly connected to the gear 5021. The synchronous belt 5022 is meshed and sleeved on several magnetic drive gear variable units 505. The servo motor 5023 is fixedly mounted on the housing 5012, and the output end of the servo motor 5023 is fixedly connected to one of the magnetic drive gear variable units 505.

[0044] In another embodiment of the present invention, the moving component 503 includes a sliding shaft 5031, a moving plate 5032, and a toothed groove 5033. The sliding shaft 5031 is slidably disposed on the elongated hole 5014, the moving plate 5032 is fixedly connected to one end of the sliding shaft 5031, the toothed groove 5033 is formed on the moving plate 5032, and the toothed groove 5033 is meshed with the gear 5021. The clamp 504 is fixedly connected to the end of the sliding shaft 5031 away from the moving plate 5032.

[0045] In this invention, the drive servo motor 5023 drives one of the magnetic drive gear units 505 at one end to rotate. Since the magnetic drive gear unit 505 is fixedly connected to the gear 5021, the gear 5021 rotates. The rotation of one of the gears 5021 drives the synchronous belt 5022 to rotate, and the synchronous belt 5022 drives multiple drive gear units 505 to rotate synchronously with the gear 5021. Since the gear 5021 is meshed with the tooth groove 5033, the drive moving plate 5032 drives the sliding shaft 5031, the clamp 504 and the cross frame 6 to slide along the elongated hole 5014, so as to achieve precise adjustment of the radius or curvature of the support arc surface.

[0046] In another embodiment of the present invention, the magnetic drive variable gear unit 505 includes a housing 5051, a slot 5052, an inner cylinder 5053, a magnetic drive component 506, and a variable gear component 507. The housing 5051 is fixedly connected to the gear 5021. The slot 5052 is opened in an annular shape at equal intervals on the outer wall of the housing 5051. The inner cylinder 5053 is fixedly disposed inside the housing 5051. The magnetic drive component 506 is disposed inside the inner cylinder 5053. The variable gear component 507 is arranged in an annular shape at equal intervals on the outer wall of the inner cylinder 5053. The end of the variable gear component 507 away from the inner cylinder 5053 is movably inserted into the slot 5052.

[0047] The core innovation of the magnetic drive variable gear unit 505 in this invention lies in the fact that it constitutes a structural unit with a variable gear ratio.

[0048] Specifically, there are 16 groups of variable tooth components 507, evenly distributed in a ring around the unit axis. The magnetic drive component 506 can receive external control signals and selectively drive all or some of the variable tooth components 507 to produce radial movement based on these signals. The magnetic drive component 506 can drive all 16 groups of variable tooth components 507 to simultaneously protrude radially out of the slot 5052 outer wall of the housing 5051, forming the maximum number of meshing teeth; it can also drive 12, 8, or 4 groups of variable tooth components 507 to protrude synchronously. This programmable selectable effective number of meshing teeth mechanism directly changes the effective working diameter when the unit is driven by the synchronous belt 5022, thereby realizing dynamic and stepped changes in the transmission ratio.

[0049] See Figure 15 When all the magnetic drive variable gear units 505 on all gears 5021 are engaged with the maximum number of teeth 16, the entire system is in a state of high transmission ratio and high torque, which is suitable for rapid and synchronous adjustment of the overall radius of the support arc surface. See Figure 16 When fine adjustment of local curvature is required, the magnetic drive variable tooth unit 505 at different positions along the arc plate can operate in different effective tooth count modes, such as 12 teeth, 8 teeth, and 4 teeth. This allows the moving components 503 at different positions to obtain different linear velocities when the input speed of the servo motor 5023 is constant, thereby achieving differential adjustment and precisely shaping the required curved arc surface.

[0050] In an embodiment of the present invention, the magnetic drive component 506 includes a magnetic block body 5061, which is inserted into the inner cylinder 5053. The magnetic block body 5061 has a multi-prism structure and has several outer wall surfaces evenly distributed along the circumference. Each outer wall surface of the magnetic block body 5061 is embedded with a set of excitation coils. The magnetic block body 5061 is adapted to the inner wall of the inner cylinder 5053.

[0051] In an embodiment of the present invention, the outer wall of the magnetic block body 5061 is provided with a plurality of electrical connection points 5063, and the electrical connection points 5063 are electrically connected to the excitation coil one by one.

[0052] In another embodiment of the present invention, a power module 5062 is also embedded inside the magnetic block body 5061. The output terminal of the power module 5062 is connected to a number of electrical connection points 5063 through a controllable on / off connection structure, and can selectively supply power to any number of electrical connection points 5063.

[0053] The power module 5062 embedded inside the magnetic block body 5061 in this invention includes a battery as an energy source, a microcontroller unit, and a multi-channel output switch circuit.

[0054] It should be specifically noted that the tooling platform 1 is equipped with a main controller, which is connected to the microcontroller in each magnetic drive gear unit 505 via a communication bus. The aforementioned multi-channel output switching circuit is composed of an integrated multi-channel power drive chip. The general-purpose input and output ports of the microcontroller are directly connected to the control pins of the drive chip. This connection relationship constitutes the aforementioned controllable on / off connection structure.

[0055] The microcontroller unit has pre-stored control programs corresponding to 16-tooth, 12-tooth, 8-tooth, and 4-tooth pins. The multi-channel output switching circuit has sixteen independent output channels, each connected to one of sixteen electrical connection points 5063. The specific means of achieving selective power supply is as follows: When the system needs to switch gear ratios, the microcontroller receives a command and drives a multi-channel output switching circuit. This switching circuit is essentially an electronic switch array that selects to connect or disconnect the circuit to any specific electrical connection point 5063.

[0056] When 16 teeth are selected, the microcontroller controls the switching circuit to close all sixteen channel switches simultaneously, so that the power supply supplies power to all electrical connection points 5063, and the sixteen excitation coils work simultaneously, pushing out all the bite blocks 5072.

[0057] When 12 teeth are selected, the microcontroller controls the switching circuit to close the switches of twelve channels, for example, to intermittently disconnect four channels, so that only the corresponding 12 electrical connection points 5063 are energized.

[0058] When 8-tooth is selected, the microcontroller controls the switching circuit to close the switches of eight channels, for example, opening one switch every other channel. See details. Figure 14 This energizes the eight electrical connection points 5063.

[0059] When 4 teeth are selected, the microcontroller controls the switching circuit to close only the switches of four channels, for example, closing one every three channels, so that the four electrical connection points 5063 are energized.

[0060] In another embodiment of the present invention, the variable tooth component 507 includes a spring 5071 and a meshing block 5072. The spring 5071 is arranged in a ring at equal intervals on the outer wall of the inner cylinder 5053. One end of the meshing block 5072 is fixedly connected to the end of the spring 5071 away from the inner cylinder 5053, and the other end of the meshing block 5072 is movably inserted into the slot 5052.

[0061] In this invention, the variable tooth component 507 is an actuator that realizes dynamic change of the number of teeth. Each set of variable tooth components 507 includes two springs 5071 and one meshing block 5072. The springs 5071 are fixed to the outer wall of the inner cylinder 5053 in a ring with equal spacing. One end of the meshing block 5072 is fixedly connected to the free end of the spring 5071, and the other end is movably inserted into the corresponding slot 5052 on the housing 5051, and can slide radially in the slot 5052.

[0062] In its natural state, the spring 5071 is in a contracted or pre-compressed state, and its restoring force pulls the biting block 5072 toward the center of the inner cylinder 5053, causing its working end to retract into the slot 5052, thereby disengaging from the synchronous belt 5022.

[0063] In an embodiment of the present invention, a magnetic element is embedded in the end face of the biting block 5072 away from the slot 5052. The magnetic element can generate a magnetic repulsion force with the excitation coil in the outer wall of the magnetic block body 5061 when energized. When the excitation coil is de-energized, the tension of the spring 5071 can drive the biting block 5072 to retract into the slot 5052.

[0064] In this invention, when a certain excitation coil is energized, the polarity of the magnetic field it generates is designed to be the same as the polarity of the permanent magnet embedded in the corresponding meshing block 5072. According to the principles of magnetism, a strong repulsive force is generated between magnetic fields of the same polarity. This magnetic repulsive force is sufficient to overcome the preload of the spring 5071, pushing the entire meshing block 5072 to slide outward along the slot 5052 until its working end protrudes beyond the outer edge of the gear 5021, achieving reliable meshing with the synchronous belt 5022.

[0065] Conversely, when the excitation coil is de-energized, the magnetic field disappears rapidly, and the magnetic repulsion is immediately released. At this time, the elastic restoring force stored in the spring 5071 becomes the dominant force, which pulls the meshing block 5072 back into the slot 5052 stably, thereby quickly and completely disengaging from the synchronous belt 5022.

[0066] Working principle: This embodiment provides a method for using a modular steel reinforcement cage fixture for concrete tower segments, including the following steps: S1, Macroscopic dimension pre-adjustment; According to the size of the target steel cage, the first pitch mechanism 2 and the second pitch mechanism 3 are activated. The first pitch mechanism 2 adjusts the overall length of the fixture, and the second pitch mechanism 3 adjusts the overall width of the fixture. This adjustment will cause the entire binding frame 4 and the module arc plate mechanism 5 above to deform, thereby pre-setting the overall outline size of the fixture platform. S2. Horizontal frame installation and support arc surface construction; After the macroscopic dimensions are adjusted to the correct position, the corresponding number of crossbeams 6 are installed onto the clamps 504 of the two modular arc plate mechanisms 5 to construct the initial support arc surface skeleton. S3. The radius of the supporting curved surface foundation is adjusted synchronously; Adjusting to radius adjustment mode, firstly, all magnetic drive gear units 505 are instructed to operate in 16-tooth mode, causing all meshing blocks 5072 to protrude synchronously and fully mesh with the synchronous belt 5022, forming a rigid synchronous transmission system. The servo motor 5023 is then started, and power is synchronously transmitted to all gears 5021 via the synchronous belt 5022. The synchronous rotation of the gears 5021, through meshing with the toothed grooves 5033 on the moving plate 5032, is converted into synchronous radial movement of all sliding shafts 5031, thereby driving all clamps 504 and crossbeams 6 to synchronously contract inward or expand outward, achieving overall adjustment of the radius of the supporting arc surface base to adapt to the diameter of the target segment. S4. Adjust the local curvature of the supporting arc surface; When adjusted to curvature adjustment mode, the magnetic drive variable tooth units 505 at different positions of the arc plate assembly 501 are instructed to operate in different effective tooth count modes. For example, the two sets of magnetic drive variable tooth units 505 located at the outermost ends are configured in a 16-tooth mode; the two sets of magnetic drive variable tooth units 505 adjacent to them on the inner side are configured in a 12-tooth mode; the two sets of magnetic drive variable tooth units 505 further towards the center are configured in an 8-tooth mode; the two sets of magnetic drive variable tooth units 505 further towards the center are configured in a 4-tooth mode; and the set of units located at the very center of the arc surface remains in a 0-tooth engagement state. This operation alters the effective transmission ratio between gears 5021 and synchronous belt 5022 at different positions. Subsequently, the servo motor 5023 is restarted. Under a constant input speed, gears 5021 with different transmission ratios will generate differentiated speeds and angular displacements, which in turn drive the crossbeam 6 at different positions via the moving component 503 to produce different radial displacements. Through this differential adjustment, the local curvature of the supporting arc surface is precisely shaped to perfectly match the specific curvature of the tapered tube segment. S5. Rebar tying operation; On the precisely shaped support arc surface, steel bars are laid out and tied according to design requirements to form a segment steel cage; S6. Finished product lifting and repositioning: After binding is completed, release the quick-locking mechanism on clamp 504 and lift the formed steel cage off the fixture as a whole; then, according to the needs of the next production task, the fixture can be reset or directly enter a new configuration adjustment cycle.
