Description

Technical Field

[0001] This invention relates to the field of automatic leveling technology, and more specifically, to an automatic leveling device for the prefabrication of concrete tower segments. Background Technology

[0002] Concrete towers are typically constructed using a precast segment splicing process, which involves prefabricating standardized tower segments in a factory and then transporting them to the construction site for assembly. This process effectively shortens the on-site construction cycle and improves the stability of project quality.

[0003] In the existing prefabrication process of concrete tower segments, after the concrete grout is injected into the inner cavity of the tower segment mold through the grouting groove, exposed concrete grout remains at the grouting groove, requiring smoothing to ensure the flatness of the segment end face. Currently, the industry commonly uses manual smoothing, where workers use trowels, scrapers, and other tools to manually smooth the concrete grout at the grouting groove. However, concrete tower segments are large in size, and the grouting groove is long. Manual smoothing requires repeated work along the groove, and due to the initial setting time of the concrete, the smoothing operation of a single segment is time-consuming, making it difficult to adapt to the pace requirements of large-scale prefabrication production. Furthermore, manual operation is susceptible to fatigue and operator skill level, leading to low work efficiency and poor smoothing quality stability. In view of this, we propose an automatic smoothing device for the prefabrication of concrete tower segments. Summary of the Invention

[0010] Preferably, the inner sidewall of the sliding cavity is provided with multiple slide rails 3, and the sidewall of the smoothing head is provided with multiple slide grooves 3. The smoothing head slides with the slide rails 3 through the slide grooves 3. The sidewall of the fixed arc block is provided with a movable chamber that communicates with the sliding cavity. The top of the smoothing head is connected to multiple slide rods, which are movably arranged in the movable chamber. The top of the slide rod is connected to a limit block. The outer circumference of the slide rod is fitted with a spring 2, which is arranged between the limit block and the bottom of the movable chamber.

[0011] Preferably, the bottom of the smoothing head is a flat structure and the top is provided with a downward pressing slope; multiple pressure rollers are rotatably arranged on the inner side wall of the rotating arc plate.

The pressure rod is slidably arranged in the inner cavity of the support block. A spring three is sleeved on the outer circumference of the pressure rod. The spring three is arranged at the bottom of the support block. The spring three can generate downward pressure on the pressure rod, so that the pressure rod can generate downward thrust on the pressure cylinder. A column groove is opened at the bottom of the pressure cylinder. A reset lever is arranged on the side wall of the pressure cylinder. The diameter of the column groove is consistent with the outer diameter of the locking pin. The column groove can be inserted and matched with the locking pin.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention designs an inner diameter guide plate and an outer diameter guide plate on the top of the tower tube segment mold. An automatic smoothing mechanism can slide within the smoothing channel between the inner diameter guide plate and the outer diameter guide plate to automatically smooth the exposed concrete at the grouting groove. This solves the problems of low efficiency and unstable quality of manual smoothing in the prior art.

[0015] 2. This invention utilizes an execution component designed with two rotating arc plates that can switch between a merged state and an unfolded state through synchronous rotation. In the merged state, the two rotating arc plates combine with the semi-cylindrical structure to form a closed roller structure. When the automatic smoothing mechanism slides within the smoothing channel, the roller structure can adhere to the surface of the concrete slurry at the grouting groove. Through the sliding driving force of the automatic smoothing mechanism and the contact friction between the roller structure and the top of the tower segment mold, the roller structure can roll on top of the concrete slurry, creating a rolling and flattening effect. During this process, the protruding concrete slurry, subjected to the squeezing force generated by the roller, flows to fill the surrounding low-lying areas, thus ensuring that the concrete slurry at the grouting groove is fully smoothed. By compacting and evenly spreading the concrete slurry to form a dense filling state, this design solves the problems caused by uneven distribution and internal density of the exposed concrete slurry at the grouting groove. Directly smoothing the concrete slurry in this state can easily result in a seemingly smooth surface with internal voids, shrinkage cracks, or uneven thickness and surface flatness due to local slurry accumulation. In the unfolded state, the smoothing head can extend from between two rotating arc plates and closely fit the surface of the concrete slurry after being compacted and spread by the roller structure. With the help of the automatic smoothing mechanism, the surface of the concrete slurry is scraped and smoothed by the smoothing channel. This design achieves the step-by-step operation of compaction followed by smoothing through the deformation of the actuator.

[0016] 3. This invention designs a locking column. When the two rotating arc plates are in a combined state, the two sliding blocks inside the locking column are subjected to the elastic force of spring one and move in opposite directions. This causes the inserts on the side walls of the sliding blocks to insert into the locking grooves of the frame, locking the frame and preventing it from sliding on the fixed block. Furthermore, the toothed edge of the locked frame forms a lock on gear four, preventing gear four from rotating. This further prevents the rotating arc plates from rotating, and the two rotating arc plates always maintain a stable combined state. When the roller structure formed by the combination of the two rotating arc plates and the semi-cylindrical structure rolls along the smoothing channel, it can effectively resist the reverse extrusion and impact force generated by the concrete slurry, preventing the rotating arc plates from accidentally unfolding or shifting. This ensures that the roller structure is stable and firm during the rolling and smoothing process of the concrete slurry.

[0017] 4. This invention utilizes multiple pressure rollers arranged rotatably on the inner wall of a rotating arc plate. These rollers, combined with the elastic force generated by spring two, drive the smoothing head to remain within the sliding cavity. As the rotating arc plate rotates, the multiple pressure rollers on its inner wall gradually contact the downward pressure slope at the top of the smoothing head, exerting downward pressure on the slope. As the rotating arc plate continues to rotate, the pressure rollers roll onto the downward pressure slope, causing the smoothing head to overcome the elastic force of spring two and move downwards. This allows the smoothing head to extend between the two rotating arc plates for smoothing operations. At this time, the smoothing head is still subject to the elastic force of spring two, resulting in an upward displacement tendency. This ensures that after the two rotating arc plates are fully rotated and unfolded, the smoothing head can be stably held in a fixed position, preventing excessive downward movement or even detachment of the smoothing head within the state switching zone. This solves the problem that if the smoothing head moves excessively downwards, the automatic smoothing mechanism cannot slide back from the state switching zone to the smoothing channel at the top of the tower tube mold.

[0018] 5. This invention achieves automated and precise switching between the combined and expanded states of the execution components by designing a pressure cylinder. In the combined state, the pressure cylinder is locked by the release gear to maintain its upper position and not interfere with the rolling operation. When switching to the expanded state, the pressure cylinder is driven by a second motor to move downward, inserts into the hole of the round cover, and then squeezes the inclined block to unlock the locking column, thereby driving the frame to slide to realize the expansion of the rotating arc plate and the extension of the smoothing head. No manual intervention is required throughout the process, ensuring continuous and stable operation.

[0019] 6. During the downward movement of the pressure cylinder, the position of the insertion hole of the circular cover is affected by the rolling motion of the roller structure, resulting in uncertainty in the position of the insertion hole. If the pressure cylinder cannot be directly inserted into the insertion hole, it will be pressed down by the pressure rod, and the bottom of the pressure cylinder will slide against the circumferential side wall of the circular cover. At this time, the toothed plate, the release gear, and the control gear are all in a separated state, and the control gear is in an idle state until the circular cover rolls with the roller structure, aligning the insertion hole with the pressure cylinder, and then the pressure cylinder is inserted into the insertion hole of the circular cover. This design achieves an adaptive and precise docking effect between the pressure cylinder and the insertion hole of the circular cover. Even if the insertion hole position is uncertain due to the rolling of the roller structure, the pressure cylinder can still adhere to the circumferential side wall of the circular cover under the downward pressure of the pressure rod and wait for alignment. During this process, the toothed plate separates from the double gears and the control gear idles, avoiding component jamming or damage caused by forced docking. It effectively solves the problem of difficult pressure cylinder docking caused by the uncertainty of the insertion hole position due to the rolling of the roller. Attached Figure Description

[0038] like Figures 1 to 17 As shown, the present invention relates to an automatic smoothing device for prefabrication of concrete tower segments, comprising a tower segment mold 1, which is a conventional mold mechanism as described in the example. The tower segment mold 1 includes a base, a fixed mold, multiple moving molds, and multiple side molds. When the moving molds, side molds, and fixed molds are closed, the shape of the enclosed inner cavity is adapted to the outer contour of the concrete tower segment to be prefabricated. A grouting groove 2 is arranged on the top of the tower segment mold 1. The grouting groove 2 is used to inject concrete slurry into the inner cavity after the mold is closed. After the concrete slurry solidifies, the concrete tower segment product is formed. An inner diameter guide plate 3 and an outer diameter guide plate 4 are installed on the top of the tower segment mold 1. A smoothing channel is formed between the inner diameter guide plate 3 and the outer diameter guide plate 4. The grouting groove 2 is arranged in the smoothing channel. An automatic smoothing mechanism 5 is slidably arranged between the inner diameter guide plate 3 and the outer diameter guide plate 4. The automatic smoothing mechanism 5 includes an execution component 6 and a state adjustment component 7.

[0039] This invention designs an inner diameter guide plate 3 and an outer diameter guide plate 4 on the top of the tower tube segment mold 1. An automatic smoothing mechanism 5 can slide in the smoothing channel between the inner diameter guide plate 3 and the outer diameter guide plate 4 to automatically smooth the exposed concrete at the grouting groove 2. This solves the problems of low efficiency and unstable quality of manual smoothing in the prior art.

[0040] In an embodiment of the present invention, the execution component 6 includes two fixed arc blocks 61, two rotating arc plates 62, a smoothing head 63, and two fixed circular plates 64. The fixed arc blocks 61 are detachably arranged between the two fixed circular plates 64, and the two fixed arc blocks 61 are combined to form a semi-cylindrical structure. The inner sidewall of the semi-cylindrical structure is provided with a sliding chamber 6101 and two rotating chambers 6102. The rotating arc plates 62 are rotatably arranged in the rotating chambers 6102. The smoothing head 63 is slidably arranged in the sliding chambers 6101. The two rotating arc plates 62 can be switched to a combined state or an unfolded state through synchronous rotation. In the combined state, the two rotating arc plates 62 and the semi-cylindrical structure are combined to form a closed roller structure. The roller structure can roll along the smoothing channel to compact and flatten the concrete slurry injected at the grouting groove 2, so that the concrete slurry forms a dense filling state. In the unfolded state, the smoothing head 63 can extend from between the two rotating arc plates 62 and adhere to the surface of the concrete slurry to perform smoothing operations.

[0041] This invention, through the design of the execution component 6, utilizes two rotating arc plates 62 that can switch between a merged state and an unfolded state via synchronous rotation. In the merged state, the two rotating arc plates 62 combine with the semi-cylindrical structure to form a closed roller structure. When the automatic smoothing mechanism 5 slides within the smoothing channel, the roller structure can adhere to the surface of the concrete slurry on the grouting groove 2. Through the sliding driving force of the automatic smoothing mechanism 5 and the contact friction between the roller structure and the top of the tower segment mold 1, the roller structure can roll on top of the concrete slurry, creating a rolling and flattening effect. During this process, the protruding concrete slurry, subjected to the squeezing force generated by the roller, flows to fill the surrounding low-lying areas, thereby ensuring that the concrete slurry at the grouting groove 2 is fully... The compaction and even spreading process creates a dense filling state, solving the problems caused by uneven distribution and internal density of the exposed concrete slurry at the grouting groove 2. Directly smoothing the concrete slurry in this state can easily result in a seemingly smooth surface but with internal voids, leading to shrinkage cracks later on, or uneven thickness of the smoothing layer and difficulty in achieving the required surface smoothness due to local slurry accumulation. In the unfolded state, the smoothing head 63 can extend between the two rotating arc plates 62, closely adhering to the surface of the concrete slurry after being compacted and spread by the roller structure. With the help of the automatic smoothing mechanism 5, which slides smoothly along the smoothing channel, the surface of the concrete slurry is scraped and smoothed. This design achieves the step-by-step operation of compaction followed by smoothing through the deformation of the actuator 6.

[0042] In an embodiment of the present invention, the inner diameter guide plate 3 is integrally formed with a suspended area guide plate 301 extending to the side of the tower tube segment mold 1, and the outer diameter guide plate 4 is integrally formed with a suspended area guide plate 401 extending to the side of the tower tube segment mold 1. A state switching area is formed between the suspended area guide plate 301 and the suspended area guide plate 401. The state switching area is used to provide switching space for the two rotating arc plates 62 to switch from the merged state to the unfolded state. At the same time, the state switching area facilitates the automatic smoothing mechanism 5 to be derailed and disassembled for maintenance, or to be connected and installed for smoothing operations.

[0043] In an embodiment of the present invention, the inner diameter guide plate 3 has multiple slide rails 302 and toothed slots 303 arranged on its side wall, and the outer diameter guide plate 4 has multiple slide rails 402 arranged on its side wall; the automatic smoothing mechanism 5 includes a frame 501, with multiple slide grooves 502 arranged on one side wall and multiple slide grooves 503 arranged on the other side wall, slide grooves 502 slidingly engaging with slide rails 302, and slide grooves 503 slidingly engaging with slide rails 402; a motor 504 is arranged in the inner cavity of the frame 501, and a bevel gear 505 is connected to the output end of the motor 504, bevel gear 506 meshing with bevel gear 505, and a gear 507 coaxially connected to bevel gear 506, which is rotatably arranged at the top of the frame 501, and meshing with toothed slots 303. This invention starts the motor 504, which drives the bevel gears 505, 506, and 507 to rotate. Since the 3rd gear 507 meshes with the toothed joint 303, the rotating 3rd gear 507 rolls on the toothed joint 303, thereby driving the equipment frame 501 to slide on the slide rails 302 and 402. The guiding and limiting function of the slide rails 302 and 402 ensures the stable sliding of the equipment frame 501 and avoids the vibration that is easily generated when the 3rd gear 507 rolls on the toothed joint 303, which would affect the stability of the automatic smoothing mechanism 5 during operation.

[0044] In an embodiment of the present invention, a plurality of inclined plates 508 are arranged on the inner sidewall of the equipment frame 501. Two inclined plates 508 are arranged in a symmetrical structure. The inclined plates 508 are used to flatten the protruding concrete piles. When there are protruding piles of concrete slurry, the inclined plates 508 move synchronously with the movement of the automatic smoothing mechanism 5, generating a forward thrust on the piled concrete slurry, so that the piled concrete slurry automatically fills the concave concrete in the process of moving forward, until the redundant concrete is pushed out of the top of the tower tube segment mold 1.

[0045] In an embodiment of the present invention, the execution component 6 is arranged between two inclined plates 508 and is rotatably arranged on the inner side wall of the equipment frame 501, and the state adjustment component 7 is arranged above the execution component 6.

[0046] In an embodiment of the present invention, a circular cover 65 is mounted on the side wall of one of the fixed circular plates 64, and an insertion hole 6501 is provided on the circumferential side wall of the circular cover 65; and a fixing block 6401 is connected to the side wall of the fixed circular plate 64, and a rotating shaft 6402 is connected to the side wall of the fixing block 6401. The rotating shaft 6402 is rotatably connected to the inner side wall of the equipment frame 501, thereby realizing the rotation state of the execution component 6 and the inner side wall of the equipment frame 501; a frame 6403 is slidably sleeved on the fixing block 6401, and a slide rail is provided on the side wall of the fixing block 6401. The frame 6403 has a sliding groove structure on its inner sidewall, which allows it to slide in conjunction with a slide rail structure. One side wall of the frame 6403 has a second toothed opening 6404, and the other side wall has the same toothed opening structure. A rotating shaft 6201 is connected to the side wall of the rotating arc plate 62, and the rotating arc plate 62 is rotatably engaged with the fixed circular plate 64 via the rotating shaft 6201. The rotating shaft 6201 passes through the side wall of the fixed circular plate 64 and is connected to a fourth gear 6202. The second toothed opening 6404 meshes with the fourth gear 6202. Through the sliding movement of the frame 6403 on the fixed block 6401, the second toothed opening 6404 drives the fourth gear 6202 to rotate, thereby controlling the combined or unfolded state of the two rotating arc plates 62.

[0047] In an embodiment of the present invention, a locking pin 6405 is connected to the top of the fixing block 6401, and a sliding hole 6406 is provided on the top of the frame 6403. The locking pin 6405 is movably inserted into the sliding hole 6406. The inner sidewall of the sliding hole 6406 is provided with multiple locking grooves 6407. Multiple guide pins 6408 are arranged inside the locking pin 6405, and two sliding blocks 6409 are slidably arranged on the guide pins 6408. The two sliding blocks 6409 are arranged symmetrically. The sliding blocks 6409 are connected by multiple springs 6410, which are sleeved on the guide post 6408. The side wall of the sliding block 6409 is integrally formed with a slope block 6411 and an insert block 6412. Both the slope block 6411 and the insert block 6412 are movably passed through the inner cavity of the locking post 6405 to its outer side. The slope block 6411 is arranged above the frame 6403, and the insert block 6412 can be in an inserted state or a separated state with the locking groove 6407.

[0048] This invention designs a locking post 6405. When the two rotating arc plates 62 are in a combined state, the two sliding blocks 6409 inside the locking post 6405 are subjected to the elastic force of spring 6410 and move in opposite directions. This causes the insert 6412 on the side wall of the sliding block 6409 to insert into the locking groove 6407 of the frame 6403, locking the frame 6403 and preventing it from sliding on the fixed block 6401. Furthermore, the toothed edge 6404 of the locked frame 6403 locks the gear 6202, preventing it from rotating. This further prevents the rotating arc plates 62 from rotating, ensuring that the two rotating arc plates 62 remain in a stable combined state. This allows the roller structure, formed by the combination of the two rotating arc plates 62 and the semi-cylindrical structure, to effectively resist the reverse extrusion and impact forces generated by the concrete slurry when rolling along the smoothing channel. This prevents the rotating arc plates 62 from accidentally unfolding or shifting, ensuring the stability and firmness of the roller structure during the rolling and smoothing of the concrete slurry.

[0049] In an embodiment of the present invention, a plurality of slide rails 6103 are arranged on the inner sidewall of the sliding chamber 6101, and a plurality of slide grooves 6301 are provided on the sidewall of the smoothing head 63. The smoothing head 63 slides with the slide rails 6103 through the slide grooves 6301. A movable chamber 6104 communicating with the sliding chamber 6101 is provided on the sidewall of the fixed arc block 61. A plurality of slide rods 6302 are connected to the top of the smoothing head 63. The slide rods 6302 are movably arranged in the movable chamber 6104. A limit block 6303 is connected to the top of the slide rods 6302. A spring 6304 is sleeved on the outer circumference of the slide rods 6302. The spring 6304 is arranged between the limit block 6303 and the bottom of the movable chamber 6104. The elastic force of spring 6304 keeps the limiting block 6303 at the top of the movable chamber 6104, thereby driving the top of the smoothing head 63 to be kept in the sliding chamber 6101. The elastic force generated by spring 6304 can drive the smoothing head 63 to be kept in the sliding chamber 6101. The bottom of the smoothing head 63 is a flat structure, and the top is provided with a downward pressure slope 6305. The flat structure at the bottom is used to smooth the concrete slurry. Multiple pressure rollers 6203 are rotatably arranged on the inner side wall of the rotating arc plate 62. When the rotating arc plate 62 rotates, the pressure rollers 6203 can roll on the downward pressure slope 6305, driving the smoothing head 63 to move downward against the elastic force of spring 6304. This invention utilizes multiple pressure rollers 6203 arranged rotatably on the inner wall of a rotating arc plate 62. These rollers, in conjunction with the elastic force generated by spring 6304, drive the smoothing head 63 to remain within the sliding chamber 6101. As the rotating arc plate 62 rotates, the multiple pressure rollers 6203 on its inner wall gradually contact the downward pressing slope 6305 at the top of the smoothing head 63, exerting downward pressure on it. As the rotating arc plate 62 continues to rotate, the pressure rollers 6203 roll against the downward pressing slope 6305, causing the smoothing head 63 to overcome the elastic force of spring 6304. The smoothing head 63 extends from between the two rotating arc plates 62 to perform a smoothing operation. At this time, the smoothing head 63 is still subject to the elastic force of the spring 6304, which causes it to tend to move upward. This ensures that after the two rotating arc plates 62 are fully rotated and unfolded, the smoothing head 63 can be stably kept in a fixed position. The smoothing head 63 will not move down too far or even fall off in the state switching zone. This solves the problem that if the smoothing head 63 moves down too far, the automatic smoothing mechanism 5 will have difficulty sliding back from the state switching zone to the smoothing channel at the top of the tower tube mold 1.

[0050] In an embodiment of the present invention, the state adjustment component 7 includes a fixed frame 701 installed on the inner wall of the equipment frame 501. A motor 702 is arranged inside the fixed frame 701. The output end of the motor 702 is meshed with a bevel gear 704 via a bevel gear 703. A bevel gear 705 is rotatably arranged on the outer wall of the fixed frame 701. The bevel gear 704 and the bevel gear 705 are coaxially connected. The bevel gear 705 is also coaxially connected to a control gear 706. A bevel gear 807 and a gear 908, a gear 10 and a worm 710, and a worm wheel 711 and a release gear 712 are also rotatably arranged on the outer wall of the fixed frame 701. The bevel gear 705 is meshed with the bevel gear 807, the gear 908 is meshed with the gear 100, and the worm 710 is meshed with the worm wheel 711.

[0051] This invention utilizes a second motor 702 to rotate at low speed, which in turn drives a fifth bevel gear 703 and a sixth bevel gear 704 to rotate at low speed. The sixth bevel gear 704 drives a coaxially connected seventh bevel gear 705 and a control gear 706 to rotate synchronously at low speed. The seventh bevel gear 705 drives a ninth gear 708 to rotate at low speed via a meshing bevel gear 707. The ninth gear 708 drives a worm gear 710 to rotate at low speed via a tenth gear 709. The worm gear 710 drives a release gear 712 to rotate at low speed via a meshing worm wheel 711. When the second motor 702 stops rotating, the release gear 712 remains stationary due to the locking effect of the worm gear 710 on the worm wheel 711. When the second motor 702 rotates, both the control gear 706 and the release gear 712 rotate.

[0052] In another embodiment of the present invention, a slide 713 is arranged on the side wall of the fixed frame 701, and a pressure cylinder 714 is slidably arranged on the slide 713. A toothed plate 715 is arranged on the side wall of the pressure cylinder 714. The toothed plate 715 can mesh with the release gear 712, or with the control gear 706, or be separated from both the release gear 712 and the control gear 706. A support block 716 is also connected to the outer side wall of the fixed frame 701. A pressure rod 717 is arranged above the pressure cylinder 714 and is slidably arranged on the slide 714. The inner cavity of the support block 716 has a spring 718 sleeved on the outer circumference of the pressure rod 717. The spring 718 is arranged at the bottom of the support block 716 and can exert downward pressure on the pressure rod 717, so that the pressure rod 717 can exert downward thrust on the pressure cylinder 714. The bottom of the pressure cylinder 714 has a column groove 719 and a reset lever 720 is arranged on the side wall of the pressure cylinder 714. The diameter of the column groove 719 is the same as the outer diameter of the locking pin 6405, and the column groove 719 can be inserted and matched with the locking pin 6405.

[0053] The present invention designs a pressure cylinder 714 such that when the two rotating arc plates 62 are in a combined state, the pressure cylinder 714 is located above the execution component 6, the toothed plate 715 meshes with the release gear 712, and the release gear 712 is kept stationary by the locking action of the worm gear 710 on the worm wheel 711, thereby forming a locking state on the toothed plate 715, so that the pressure cylinder 714 is always kept above the execution component 6 and does not interfere with the execution component 6. This ensures that the roller structure in the combined state can roll stably along the smoothing channel to compact and flatten the concrete slurry injected at the grouting groove 2, so that the concrete slurry forms a dense filling state. When it is necessary to control the two rotating arc plates 62 to form an unfolded state, it is only necessary to first move the automatic smoothing mechanism 5 back through the smoothing channel towards the state switching area, and then start the motor 702 to rotate at low speed, driving the control gear 706 and the release gear 712 to rotate at low speed. During this process, the release gear 712 drives the toothed plate 715 to move down, that is, the pressure cylinder 714 moves down until it separates from the toothed plate 715. During the downward movement of the pressure cylinder 714, it drives the roller structure to roll in coordination with the return movement of the automatic smoothing mechanism 5. If the pressure cylinder 714 can be inserted into the insertion hole 6501 on the circumferential side wall of the round cover 65, it forms a rotation restriction on the roller structure, and the roller structure stops rolling. As the automatic smoothing mechanism 5 moves to the state switching area, and the toothed plate 715 meshes with the control gear 706, the control gear 706 drives the toothed plate 715 to continue to move down, and the pressure cylinder 714 to continue to move down. If the pressure cylinder 714 is not directly inserted into the insertion hole 6501 on the circumferential side wall of the cover 65, the pressure cylinder 714 will be pressed down by the pressure rod 717. The bottom of the pressure cylinder 714 will slide against the circumferential side wall of the cover 65. At this time, the toothed plate 715, the release gear 712, and the control gear 706 are all in a separated state. The control gear 706 is in an idle state until the cover 65 rolls with the roller structure, aligning the insertion hole 6501 with the pressure cylinder 714. Then the pressure cylinder 714 is inserted into the insertion hole 6501 of the cover 65. Similarly, the toothed plate 715 will mesh with the control gear 706. The control gear 706 will drive the toothed plate 715 to continue to move downward, and the pressure cylinder 714 will continue to move downward. As the pressure cylinder 714 continues to move downward, the inner wall of the column groove 719 gradually presses against the inclined block 6411 on the side wall of the sliding block 6409. Utilizing the inclined structure of the inclined block 6411, the downward pressure force is converted into a horizontal force that drives the two sliding blocks 6409 to move closer to each other along the guide post 6408. This causes the sliding blocks 6409 to overcome the elastic force of the spring 6410 and retract into the inner cavity of the locking post 6405, thereby driving the insert block 6412 to retract synchronously and release the insertion lock with the locking groove 6407 in the sliding hole 6406 of the frame 6403. At this time, the control gear 706 continues to drive the pressure cylinder 714 downward through the toothed plate 715. The pressure cylinder 714 presses down on the top of the frame 6403, driving the frame... 6403 slides downward along the slide rail structure of the fixed block 6401. During the sliding process, the toothed edge 6404 on its side wall meshes with the gear 6202 of the rotating arc plate 62, driving the two rotating arc plates 62 to rotate synchronously around the rotating shaft 6201 and unfold, disengaging from the merged state with the semi-cylindrical structure. At the same time, the pressure roller 6203 on the inner side wall of the rotating arc plate 62 gradually contacts the downward pressure slope 6305 on the top of the smoothing head 63 as it rotates, and pushes the smoothing head 63 to overcome the elastic force of the spring 6304 and move downward along the slide rail 6103 through the rolling action, extending from between the two rotating arc plates 62, completing the switch from the merged rolling state to the unfolded smoothing state. The entire process, with the help of the precise positioning, unlocking and driving integrated design of the pressure cylinder 714, combined with the synergistic effect of gear transmission and elastic structure, realizes the automation and precision of the state switching of the execution component 6, and requires no manual intervention throughout the process, ensuring the continuity and stability of the operation process.

[0054] Working principle: This embodiment provides an automatic smoothing device for the prefabrication of concrete tower segments. In use, concrete slurry is first injected into the inner cavity of the tower segment mold 1 through the grouting groove 2 at the top of the mold to ensure that the slurry is filled in place. Then, the motor 504 is started, and its output end drives the bevel gear 505 to rotate. Through the meshing transmission with the bevel gear 506, the gear 507 is driven to roll on the tooth 303, thereby driving the equipment frame 501 to slide smoothly along the slide rail 302 and the slide rail 402 in the smoothing channel. At this time, the execution component 6 is in a combined state. The two rotating arc plates 62 and the fixed arc block 61 combine to form a closed roller structure. As the equipment frame 501 moves, it rolls on the surface of the concrete slurry, compacts and flattens the slurry, and makes it form a dense filling state. The inclined plate 508 on the inner side of the equipment frame 501 simultaneously pushes flat the protruding concrete pile. When the automatic smoothing mechanism 5 returns to the smoothing channel and moves towards the state switching area, the second motor 702 is started. Through multiple transmission stages such as the fifth bevel gear 703 and the sixth bevel gear 704, the release gear 712 and the control gear 706 are driven to rotate. The release gear 712 drives the toothed plate 715 and the pressure cylinder 714 to move down along the slide 713. Under the downward pressure of the pressure rod 717, the pressure cylinder 714 adaptively aligns with the insertion hole 6501 of the round cover 65 and is inserted, thus restricting the rotation of the roller structure. The continuously moving pressure cylinder 714 presses the inclined block 6411 through the column groove 719, causing the sliding block 6409 to compress the spring 6410, and the insert block 6412 to disengage from the locking groove 6407, unlocking the frame 6403; then the pressure cylinder 714 continues to press down on the frame 6403, and through the meshing of the toothed mouth 6404 and the gear 6202, it drives the rotating arc plate 62 to unfold around the rotating shaft 6201, and the pressure roller 6203 on its inner side rolls the downward pressure inclined surface 6305 of the smoothing head 63, so that the smoothing head 63 overcomes the elastic force of the spring 6304 and moves down and extends along the slide rail 6103; Finally, motor 504 reverses its rotation, driving equipment frame 501 to slide back, and the extended smoothing head 63 fits against the compacted slurry surface to perform precise smoothing.
