Description

Technical Field

[0001] This invention relates to the field of prefabricated building materials technology, and in particular to a modular prefabrication and rapid splicing device for wind power foundation steel reinforcement skeleton. Background Technology

[0002] To reduce the difficulty of wind power foundation construction and increase construction speed, the steel reinforcement cage used in wind power foundations generally adopts modular prefabrication construction. However, the splicing and assembly of modular steel reinforcement cages requires a special splicing and positioning device to achieve efficient operation. For example, the patent with application number CN202311703638.7 discloses a steel reinforcement cage for prefabricated piles, which can effectively complete equidistant positioning welding while ensuring the original shape of the clamps and steel bars.

[0003] Existing precast steel reinforcement splicing devices, such as those mentioned above, typically employ two independent positioning mechanisms in actual use to position the steel reinforcement module and the clamp structure separately, and then connect and fix them sequentially. While this method ensures the stability of the positioning, it has significant drawbacks. The positioning and connection of the steel reinforcement and the clamp need to be carried out step by step, making it impossible to achieve synchronous positioning and fixing, resulting in a long on-site splicing time. Summary of the Invention

[0004] This invention relates to a modular prefabrication and rapid splicing device for wind power foundation steel reinforcement skeletons. By rotating the splicing transmission screw via a handle, the device synchronously drives the trigger slider and transmission slider forward. The trigger push block, through its inclined surface, drives the steel reinforcement sliding clamp to move laterally outward, automatically clamping the steel reinforcement structure using the sliding clamp groove to ensure stable welding positioning. Simultaneously, the transmission push block pushes the force-bearing push plate, causing the clamp positioning seat to open and close vertically. Combined with the fault-tolerant guide plate, this automatically centers and precisely positions the clamp structure, achieving simultaneous positioning and clamping of the steel reinforcement structure and the clamp structure in one operation. This results in high positioning accuracy, fewer operation steps, and significantly improved prefabrication and splicing efficiency.

[0005] In a first aspect, this invention provides a modular prefabrication and rapid splicing device for a wind power foundation steel reinforcement frame, specifically comprising: a splicing fixing base, wherein splicing insertion holes are provided at the four corners of the front side of the splicing fixing base; a steel reinforcement structure is inserted into the splicing insertion holes; a clamping structure is fitted onto the steel reinforcement structure; steel reinforcement sliding clamps are slidably installed on the left and right sides inside the splicing fixing base; sliding clamping grooves are provided at the upper and lower ends of the outer side of the steel reinforcement sliding clamps; a force-bearing push groove is provided at the inner end of the steel reinforcement sliding clamps; the force-bearing push groove has an inclined internal structure; a transmission base is inserted and fixed at the center of the splicing fixing base; a splicing transmission screw is rotatably installed at the center of the transmission base; a row of linear guide grooves A is provided on the top of the transmission base; a linear guide groove B is provided on the rear side of the top of the transmission base; a trigger is slidably installed inside the linear guide groove B. A slider; the trigger slider is connected to the splicing transmission screw via threads; trigger push blocks are fixedly installed on the left and right sides of the trigger slider; the front outer end of the trigger push block has an inclined structure; a transmission slider is slidably installed inside the stroke linear guide groove A; the transmission slider is connected to the splicing transmission screw via threads; transmission push blocks are symmetrically fixedly installed at the upper and lower ends of the front side of the transmission slider; the front end of the transmission push block has an inclined structure; guide slide plates are slidably installed on the left and right sides of the transmission base; a connecting horizontal plate is fixedly installed at the outer end of the guide slide plate; a clamping positioning clamp is fixedly installed on the outer side of the connecting horizontal plate; a clamping groove is opened inside the clamping positioning clamp; a fault-tolerant guide plate is fixedly installed at the outer end of the clamping positioning clamp; the fault-tolerant guide plate has an inclined structure; a force-bearing push plate is fixedly installed at the center position on the inner side of the connecting horizontal plate; the rear side of the force-bearing push plate has an inclined structure.

[0006] Furthermore, a spring is embedded between the outer side of the rebar sliding clamp and the inner outer side of the splicing fixing seat; the sliding clamp groove has an arc-shaped structure, and friction grooves are formed inside the sliding clamp groove.

[0007] Furthermore, the clamp positioning seat is located inside the clamp structure; a support crossbar is fixedly installed at the bottom of the splicing fixing seat; and a handle is fixedly installed at the rear end of the splicing transmission screw.

[0008] Furthermore, embedded protrusions are fixedly installed on the left and right sides of the transmission base; a spring is embedded between the inner side of the connecting cross plate and the outer side of the embedded protrusions.

[0009] Furthermore, when the splicing transmission screw rotates, it will cause the trigger slider and the transmission slider to move along the stroke linear guide groove B and the stroke linear guide groove A respectively under the action of the thread.

[0010] Furthermore, when the trigger slider moves forward with the trigger push block, the inclined surface of the trigger push block will push against the inclined surface of the force-receiving push groove.

[0011] Furthermore, after being pushed, the inclined surface of the force-bearing groove will convert the forward force into a lateral outward force and provide it to the rebar sliding clamp; after the rebar sliding clamp moves outward, it will use the sliding clamp groove to clamp the rebar structure.

[0012] Furthermore, when the transmission slider moves forward, the inclined surface of the transmission push block will push against the inclined surface of the force-bearing push plate.

[0013] Furthermore, after being pushed, the inclined surface of the force-bearing push plate will convert the forward force into a vertical outward force, which will be provided to the connecting horizontal plate and the guide slide plate.

[0014] Furthermore, when the guide slide plate and connecting cross plate move outward, the fault-tolerant guide plate will use its own tilting structure to automatically center the clamping structure and guide it into the clamping groove of the clamping positioning clamp.

[0015] This invention provides a modular prefabrication and rapid assembly device for wind power foundation steel reinforcement cages, which has the following beneficial effects: 1. This invention abandons the traditional on-site manual binding mode and adopts modular prefabrication construction, which effectively avoids many drawbacks of on-site binding in the field, greatly shortens the on-site construction cycle, reduces labor costs and work intensity, and achieves rapid module splicing through a special positioning and locking mechanism, solving the problems of low positioning accuracy and cumbersome docking process in traditional splicing methods.

[0016] 2. This invention uses a single screw to rotate and drive, which can simultaneously complete the positioning and clamping of multiple sets of clamping structures and steel reinforcement structures, merging two independent positioning processes into one. This significantly simplifies the operation process, improves splicing and prefabrication efficiency, and, in conjunction with the automatic correction function of the fault-tolerant guide plate, can effectively ensure the assembly accuracy of the clamping structure and steel reinforcement structure. It fundamentally solves the defects of existing similar devices that require step-by-step positioning and connection, resulting in low splicing efficiency, easy positioning deviation, and poor adaptability.

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please refer to Figures 1 to 8 Example 1: This invention proposes a modular prefabrication and rapid splicing device for wind power foundation steel reinforcement skeleton, comprising: a splicing fixing base 1, with splicing insertion holes 2 at the four corners of the front side of the splicing fixing base 1; steel reinforcement structures 19 are inserted into the splicing insertion holes 2; a clamping structure 20 is fitted onto the steel reinforcement structure 19; steel reinforcement sliding clamps 3 are slidably installed on the left and right sides inside the splicing fixing base 1; sliding clamping grooves 4 are opened at the upper and lower ends of the outer side of the steel reinforcement sliding clamps 3; a force-bearing push groove 5 is opened at the inner end of the steel reinforcement sliding clamps 3; the force-bearing push groove 5 has an inclined internal structure; a transmission base 6 is inserted and fixed at the center of the splicing fixing base 1; a splicing transmission screw 7 is rotatably installed at the center of the transmission base 6; a row of linear guide grooves A8 is opened on the top of the transmission base 6; a linear guide groove B9 is opened on the rear side of the top of the transmission base 6; a trigger slider 10 is slidably installed inside the linear guide groove B9; the trigger slider 10 is connected to... The transmission base 6 is connected to the splicing transmission screw 7 via threads; trigger push blocks 11 are fixedly installed on the left and right sides of the trigger slider 10; the front outer end of the trigger push block 11 has an inclined structure; the transmission slider 12 is slidably installed inside the stroke linear guide groove A8; the transmission slider 12 is connected to the splicing transmission screw 7 via threads; the transmission push blocks 13 are symmetrically fixedly installed at the upper and lower ends of the front side of the transmission slider 12; the front end of the transmission push block 13 has an inclined structure; the transmission base 6 is slidably installed on the left and right sides of the transmission base 6; the outer end of the guide slide plate 14 is fixedly installed with a connecting horizontal plate 15; the outer side of the connecting horizontal plate 15 is fixedly installed with a clamping positioning clamp 16; the clamping positioning clamp 16 has a clamping groove inside; the outer end of the clamping positioning clamp 16 is fixedly installed with a fault-tolerant guide plate 17; the fault-tolerant guide plate 17 has an inclined structure; the inner side of the connecting horizontal plate 15 is fixedly installed with a force-bearing push plate 18 at the center position; the rear side of the force-bearing push plate 18 has an inclined structure.

[0022] In Example 2, based on Example 1, a spring is embedded between the outer side of the rebar sliding clamp 3 and the inner outer side of the splicing fixing seat 1; the sliding clamp groove 4 has an arc-shaped structure, and friction grooves are formed inside the sliding clamp groove 4; the clamp positioning clamp 16 is located inside the clamp structure 20; a support crossbar 21 is fixedly installed at the bottom of the splicing fixing seat 1; a handle is fixedly installed at the rear end of the splicing transmission screw 7; embedded protrusions 22 are also fixedly installed on the left and right sides of the transmission base 6; a spring is embedded between the inner side of the connecting crossbar 15 and the outer side of the embedded protrusions 22; when the splicing transmission screw 7 rotates, it will move the trigger slider 10 and the transmission slider 12 along the stroke linear guide groove B9 and the stroke linear guide groove A8 respectively under the action of the thread; the rebar structure 19 is inserted into the splicing insertion hole 2, and then the clamp structure is... The clamp 20 is mounted on the steel structure 19. During mounting, the clamp structure 20 needs to be kept outside the clamp positioning seat 16. Then, the splicing transmission screw 7 is rotated by the handle, so that the trigger slider 10 and the transmission slider 12 move forward along the stroke linear guide groove B9 and the stroke linear guide groove A8 respectively under the action of rotation. When the trigger slider 10 moves forward, the inclined surface of the trigger push block 11 on the trigger slider 10 will push the inclined surface of the force push groove 5. After being pushed, the inclined surface of the force push groove 5 will convert the forward force into the lateral outward force and provide it to the steel sliding clamp 3, so that the two steel sliding clamps 3 move left and right relative to each other. After the steel sliding clamps 3 move outward relative to each other to a certain position, they will clamp the steel structure 19 with the sliding clamp groove 4 to ensure the stability of the steel structure 19 during the subsequent prefabrication and welding.

[0023] In Example 3, based on Example 2, when the trigger slider 10 moves forward with the trigger push block 11, the inclined surface of the trigger push block 11 pushes against the inclined surface of the force-receiving push groove 5; after being pushed, the inclined surface of the force-receiving push groove 5 converts the forward force into a lateral outward force and provides it to the rebar sliding clamp 3; after the rebar sliding clamp 3 moves outward, it uses the sliding clamp groove 4 to clamp the rebar structure 19; when the transmission slider 12 moves forward, the inclined surface of the transmission push block 13 pushes against the inclined surface of the force-receiving push plate 18; after being pushed, the inclined surface of the force-receiving push plate 18 converts the forward force into a vertical outward force and provides it to the connecting horizontal plate 15 and the guide slide plate 14; when the guide slide plate 14 and the connecting horizontal plate 15 move outward, the fault-tolerant guide plate 17 uses its own inclined structure to automatically center the clamping structure 20 and guide it into the clamping groove of the clamping positioning clamp 16; when the transmission slider 12 moves forward, the inclined surface of the transmission push block 13 pushes against the inclined surface of the force-receiving push plate 18, and the force-receiving push plate 18... When the inclined surface of the push plate 18 is pushed, it converts the forward force into a vertical outward force, which is provided to the connecting horizontal plate 15 and the guide plate 14. This causes the guide plates 14 and the connecting horizontal plate 15 on both sides to move up and down relative to each other with the corresponding clamp positioning seats 16. During the movement, the fault-tolerant guide plate 17 will use its own inclined structure to automatically center the outer clamp structure 20 and guide it into the clamping groove of the clamp positioning seat 16. This not only completes the positioning of the clamp structure 20, which is convenient for prefabrication and welding with the steel structure 19, but also corrects the installation deviation of the clamp structure 20 within a certain range. Thus, the quick splicing and positioning of the steel structure 19 and the clamp structure 20 is completed. Next, the steel structure 19 and the clamp structure 20 are welded together using welding equipment. After welding, a modular steel skeleton is formed. After the welding cools down, the splicing transmission screw 7 is rotated counterclockwise to restore the positioning structure. At this time, the modular steel skeleton can be quickly removed from the device.

[0024] The working principle of this embodiment is as follows: First, the reinforcing steel structure 19 is inserted into the splicing socket 2. Then, the clamping structure 20 is fitted onto the reinforcing steel structure 19. During the fitting process, the clamping structure 20 must be positioned outside the clamping positioning seat 16. Next, the operator rotates the splicing transmission screw 7 via the handle. When the splicing transmission screw 7 rotates, it drives the trigger slider 10 to move forward synchronously along the travel linear guide groove B9 and the transmission slider 12 along the travel linear guide groove A8. When the trigger slider 10 moves forward, its trigger push block 11 presses against the inclined surface of the force-receiving push groove 5, converting the forward movement force of the trigger slider 10 into a lateral outward movement force transmitted to the reinforcing steel sliding seat 3. This causes the two reinforcing steel sliding seats 3 to move relative to each other left and right. When the reinforcing steel sliding seat 3 moves to the designated position, it securely clamps the reinforcing steel structure 19 through its own sliding clamping groove 4, ensuring the positioning stability of the reinforcing steel structure 19 during subsequent prefabrication and welding, and preventing displacement during welding. Simultaneously, when the transmission slider 12 moves forward, its transmission push block 13... The inclined surface and the inclined surface of the force-bearing push plate 18 press together, converting the forward movement force of the transmission slider 12 into a vertical outward movement force, which is transmitted to the connecting horizontal plate 15 and the guide slide plate 14. This causes the guide slide plates 14 and the connecting horizontal plate 15 on the upper and lower sides to drive the corresponding clamp positioning seats 16 to move up and down relative to each other. During the movement, the fault-tolerant guide plate 17 uses its own inclined structure to automatically center the clamp structure 20, which is sleeved on the outside of the steel structure 19, and accurately guide it into the clamping groove of the clamp positioning seat 16, thus realizing the rapid positioning of the clamp structure 20. This facilitates the prefabrication and welding of the steel reinforcement structure 19 with the clamp structure 20, and can also correct the installation deviation of the clamp structure 20 within a certain range, ensuring the splicing accuracy. Thus, the rapid splicing and positioning of the steel reinforcement structure 19 and the clamp structure 20 is completed. Then, the two are welded together by welding equipment to form a modular steel reinforcement skeleton. After the weld has cooled, the splicing transmission screw 7 is rotated counterclockwise to reset each positioning and clamping structure. The prefabricated modular steel reinforcement skeleton can then be quickly disassembled from this device, which is convenient for subsequent transportation and on-site splicing.
