Description

Technical Field

[0001] The present invention relates to the field of concrete pouring, and specifically relates to a concrete wall panel pouring device for civil engineering. Background Art

[0002] In the field of civil engineering, as an important building component, the pouring quality of concrete wall panels directly affects the overall structural safety and stability of buildings. There are many problems with traditional concrete wall panel pouring devices in practical applications. First of all, after the concrete is transported to the construction site, during the process of transferring from the transportation equipment to the pouring formwork, phenomena such as concrete segregation and stratification are likely to occur. Common grouting equipment cannot effectively maintain the uniformity of the concrete during the pouring process, resulting in uneven internal quality of the poured wall panels and weak strength areas.

[0003] Secondly, there are also deficiencies in the vibration link. Some vibration devices are difficult to accurately control the vibration depth and time. Either the vibration is insufficient, making it impossible to completely eliminate the air bubbles and gaps inside the concrete, affecting the strength and durability of the wall panels; or the vibration is excessive, causing the concrete aggregates to sink and the cement paste to float, also reducing the quality of the wall panels. Moreover, the vibration device and the leveling device are often independent of each other, and the work connection is not smooth, resulting in low construction efficiency.

[0004] Furthermore, in terms of the leveling operation, the traditional screed board has a simple structure and cannot flexibly adjust the angle according to the actual situation of the concrete surface during the leveling process. For large-area concrete wall panels, it is difficult to ensure the consistency of the surface flatness, and problems such as uneven surface strength and shrinkage cracks are likely to occur, affecting the appearance and service life of the wall panels.

[0005] In addition, the existing pouring devices have a low degree of automation, and each process requires frequent manual operation and intervention, which not only increases the labor intensity and labor costs, but also the human factors have a greater impact on the pouring quality, making it difficult to ensure that the quality of each concrete wall panel can reach a high standard. At the same time, the overall structural design of the equipment is not compact and reasonable enough, occupying a large space, and is greatly restricted in use at some construction sites with narrow spaces. In summary, it is of great practical significance to develop a new type of device that is efficient, precise, highly automated and can ensure the pouring quality of concrete wall panels. Summary of the Invention

[0006] Based on this, it is necessary to provide a concrete wall panel pouring device for civil engineering in view of the problems of the existing technology.

[0007] In order to solve the problems of the existing technology, the technical solution adopted by the present invention is as follows:

[0008] A concrete wall panel pouring device for civil engineering, including a carrier for positioning the formwork, and further including:

The moving direction of the pushing frame is opposite to that of the sliding seat. A leveling mechanism is arranged on the pushing frame. The leveling mechanism includes a reciprocating sliding table and a trowel plate with an adjustable inclination angle.

[0014] Furthermore, the leveling mechanism further includes a driving motor, a screw rod, a screw sleeve and two limiting rods. The driving motor is fixedly connected to one end of the pushing frame. The screw rod is rotatably arranged in the middle of the pushing frame and one end thereof is fixedly connected to the output end of the driving motor coaxially. The screw sleeve is threadedly connected to the screw rod. The two limiting rods are arranged on both sides of the screw rod and both ends thereof are fixedly connected to the pushing frame respectively. The sliding table is fixedly connected to the screw sleeve and is slidably connected to the limiting rods on both sides respectively.

[0015] Furthermore, the leveling mechanism further includes a pushing baffle, two deflecting frames, two pressing rods, two power racks, two power gears, two reversing gears, two power pulleys and two deflecting pulleys. The two deflecting frames are respectively fixedly connected to the lower end of the sliding table. The two deflecting pulleys are respectively rotatably connected to the two deflecting frames. The two deflecting pulleys are respectively fixedly connected to the screeding plate. The two power pulleys are respectively arranged above the two deflecting pulleys and are rotatably connected to the side wall of the sliding table. The two reversing gears are respectively fixedly connected to the two power pulleys coaxially. The two power gears are respectively arranged above the two reversing gears and are meshed with the reversing gears. The two power racks are respectively slidably connected to both sides of the sliding table and are meshed with the corresponding power gears. The two pushing baffles are respectively arranged at both ends of the sliding table and are fixedly connected to the ends of the power racks. The two pressing rods are respectively fixedly connected to the side of the pushing frame close to the sliding table. The sliding table will drive the pushing baffle to collide with the pressing rod when approaching the pressing rod. The pushing baffle is the movable end of the leveling mechanism.

[0016] Furthermore, the leveling mechanism further includes a positioning sliding plate, a limiting short pin, a sliding block, a movable magnetic block and a positioning magnetic block. The positioning sliding plate is slidably connected to the sliding table. A V-shaped limiting hole is formed in the middle of the positioning sliding plate. Both ends of the positioning sliding plate are fixedly connected to the movable end of the leveling mechanism. A limiting groove is formed inside the sliding table. The sliding block is slidably connected to the limiting groove. One end of the limiting short pin is fixedly connected to the sliding block and the other end is slidably connected to the V-shaped limiting hole. The movable magnetic block is fixedly connected to the lower end of the sliding block. The positioning magnetic block is arranged below the movable magnetic block and is fixedly connected to the sliding table. The movable magnetic block is attracted to the positioning magnetic block by magnetic force when they are in contact with each other.

[0017] The beneficial effects of the present invention compared with the prior art are as follows:

[0018] Firstly, in the grouting mechanism of the present device, the stirring motor drives the stirring paddle to continuously stir the concrete in the grouting tank, effectively preventing the concrete from stratifying and precipitating during the waiting process for pouring. Compared with the traditional device, it can ensure that the concrete poured into the formwork always maintains a uniform mix ratio and good fluidity, greatly improving the internal quality of the concrete wall panel, enhancing the strength and durability of the wall panel, reducing the quality hidden dangers caused by uneven concrete, and making the structure of the building more stable and safe;

[0019] Second: In this device, the vibrator and the screeding mechanism are linked through transmission structures such as racks and gears. When vibrating, the screeding plate automatically moves away from the formwork to avoid damage. After vibration, the screeding plate quickly approaches and performs the screeding operation. This precise collaborative working mode greatly improves the construction efficiency, reduces the construction time, and at the same time ensures the vibration and screeding effects, making the surface of the concrete wall panel smoother and the internal quality more reliable, thus enhancing the overall construction quality compared with the traditional independently operated vibrator and screeding device;

[0020] Third: The screeding plate in the screeding mechanism of this device can adjust the corresponding tilt angle according to the moving direction during the moving process. When the sliding table moves to both ends of the screw rod, through the gear and rack transmission structure, the screeding plate deflects at an angle, and its two arc-shaped corners on both sides are used to better adapt to the unevenness of the concrete surface, and perform fine screeding on the concrete. Compared with the traditional screeding plate with a fixed angle, it can effectively improve the flatness and smoothness of the concrete surface, reduce problems such as uneven surface strength and dry shrinkage cracks, extend the service life of the concrete wall panel, and enhance the aesthetic degree and quality of the building.

Detailed implementation mode

[0031] In order to further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation modes.

[0032] Refer to Figures 1 to 8 , a concrete wallboard pouring device for civil engineering, including a loading platform 2 for positioning the template 1, and further including:

[0033] A positioning frame 4 fixedly connected to the output end of the three-axis moving mechanism 3, the positioning frame 4 is arranged beside the loading platform 2, an electric push rod 9 fixedly connected to the positioning frame 4 and with the output end arranged downward, a sliding seat 10 fixedly connected to the output end of the electric push rod 9, the vibrator 5 is fixedly connected to the upper end of the positioning frame 4 and the output end is flexibly connected to the sliding seat 10, a pushing frame 11 is vertically slidably arranged on the positioning frame 4, the moving direction of the pushing frame 11 is opposite to that of the sliding seat 10, a smoothing mechanism 13 is arranged on the pushing frame 11, the smoothing mechanism 13 includes a reciprocating slide 18 and a smoothing plate 20 with an adjustable inclination angle. When the smoothing plate 20 contacts the upper end of the concrete in the template 1, the slide 18 drives the smoothing plate 20 to smooth the concrete through reciprocating movement. A grouting mechanism 35 is arranged at the bottom of the positioning frame 4. The grouting mechanism 35 includes a grouting box 36 communicated with the tank body of the concrete mixing truck and capable of tilting. A feeding port 37 is formed at the lower part of the side of the grouting box 36 close to the smoothing plate 20. A box door 47 is slidably arranged on the side of the grouting box 36 close to the feeding port 37. A stirring paddle 41 is rotatably arranged inside the grouting box 36. The stirring paddle 41 is used to keep the concrete inside the grouting box 36 in a flowing state during the pouring process. A feeding plate 48 is slidably arranged at the bottom of the grouting box 36. When the grouting box 36 tilts, the feeding plate 48 moves towards the direction close to the smoothing plate 20 and the box door 47 moves upward.

[0034] When this device is in operation, the wall formwork 1 for shaping concrete is placed on the bearing platform 2. Subsequently, the three-axis moving mechanism 3 drives the positioning frame 4 to approach the bearing platform 2. At this time, the grouting box 36 temporarily stores the concrete transported by the concrete mixer truck. The stirring paddle 41 stirs the concrete in the grouting box 36 to prevent the concrete from stratifying in the grouting box 36. Subsequently, under the action of the grouting mechanism 35, the grouting box 36 tilts. During the tilting process of the grouting box 36, the feeding plate 48 moves towards the screeding plate 20 to facilitate guiding the concrete in the grouting box 36. At the same time, the box door 47 moves upward to avoid the feeding port 37. At this time, the concrete will fall into the formwork 1 to complete the pouring of the wall panel.

[0035] After the pouring is completed, the output end of the vibrator 5 extends into the formwork 1 to vibrate the concrete to eliminate the air bubble gaps in the concrete. After the vibration is completed, as the output end of the vibrator 5 leaves the concrete, the screeding plate 20 moves downward and approaches the upper end of the concrete. Subsequently, under the action of the screeding mechanism 13, the screeding plate 20 levels the concrete to avoid problems such as uneven strength and dry shrinkage cracks on the surface, thereby ensuring the consistency and stability of the overall performance of the concrete.

[0036] In order to achieve the tilting of the grouting box 36 and drive the stirring paddle 41 so that the concrete in the grouting box 36 can be poured into the formwork 1, the following features are specifically set:

[0037] The grouting mechanism 35 further includes a deflection motor 39, a stirring motor 40, and two positioning seats 38. The two positioning seats 38 are respectively arranged on both sides of the grouting box 36 and are fixedly connected to the positioning frame 4. The deflection motor 39 is fixedly connected to one of the positioning seats 38 and the output end is fixedly connected to the side wall of the grouting box 36. The stirring motor 40 is fixedly connected to one side of the grouting box 36 and the output end is fixedly connected to the stirring paddle 41. When the deflection motor 39 is started, the rotation of the output shaft drives the grouting box 36 to deflect around the connection point of the positioning seat 38, thereby realizing the tilting action of the grouting box 36 and facilitating the pouring of the internal concrete into the formwork 1. The stirring motor 40 is installed on one side of the grouting box 36, and its output end is connected to the stirring paddle 41. When the stirring motor 40 works, it drives the stirring paddle 41 to rotate at a high speed inside the grouting box 36 to continuously stir the concrete, preventing the concrete from stratifying and precipitating during the waiting for pouring process, ensuring the uniformity and fluidity of the concrete, and providing guarantee for high-quality pouring operations.

[0038] In order to achieve the upward displacement of the box door 47 when the feeding plate 48 moves towards the screeding plate 20, the following features are specifically set:

[0039] The grouting mechanism 35 further includes a biaxial motor 42, two main belt pulleys 43, four auxiliary belt pulleys 44, four auxiliary gears 45 and four auxiliary racks 46. The biaxial motor 42 is fixedly connected to the grouting box 36. The two main belt pulleys 43 are coaxially fixedly connected to the two output ends of the biaxial motor 42. Two auxiliary belt pulleys 44 are respectively arranged beside each main belt pulley 43. The two auxiliary belt pulleys 44 are respectively rotatably connected to the side wall of the grouting box 36 and are in transmission connection with the corresponding main belt pulley 43 through a belt. The four auxiliary gears 45 are respectively coaxially fixedly connected to the four auxiliary belt pulleys 44. One auxiliary rack 46 is fixedly connected to each of the two sides of the box door 47 and the feeding plate 48. The auxiliary rack 46 meshes with the corresponding auxiliary gear 45. When the biaxial motor 42 is started, the biaxial motor 42 drives the corresponding auxiliary belt pulley 44 to rotate through the main belt pulley 43. After the auxiliary belt pulley 44 rotates, it drives the auxiliary rack 46 to move through the auxiliary gear 45. The movement of the auxiliary rack 46 can make the feeding plate 48 move in the direction close to the screed plate 20, and at the same time drive the box door 47 to move upward, realizing the opening of the feeding port 37, facilitating the smooth outflow of the concrete in the grouting box 36 for pouring operations, and the moving speed and position of the feeding plate 48 and the box door 47 can be flexibly controlled as needed during the pouring process.

[0040] In order to facilitate the screed plate 20 to level the concrete in the formwork 1 during the movement, the following features are specifically set:

[0041] Arc-shaped corners 21 are respectively formed on both sides of the screed plate 20. The screed plate 20 levels the concrete in the formwork 1 through the arc-shaped corners 21. When the screed plate 20 approaches the concrete in the formwork 1, the arc-shaped corners 21 first contact the concrete surface. The arc-shaped corners 21 make the concrete more evenly distributed on the surface of the formwork 1 during the process of being squeezed and pushed, filling the tiny depressions and gaps on the surface, thereby realizing the efficient leveling of the concrete. Compared with the ordinary straight screed plate 20, the screed plate 20 with arc-shaped corners 21 can better adapt to the unevenness of the concrete surface, reduce problems such as scratches and accumulations on the concrete surface, and effectively improve the flatness and smoothness of the concrete surface.

[0042] In order to realize that when the vibrator 5 extends into the formwork 1 to vibrate the concrete, the screed plate 20 moves away from the formwork 1; and when the vibrator 5 leaves the formwork 1, the screed plate 20 approaches the formwork 1 and levels the upper end of the concrete in the formwork 1, the following features are specifically set:

[0043] The device further includes two first racks 6, two main gears 7 and two second racks 8. The two first racks 6 are respectively fixedly connected to both sides of the sliding seat 10. The two main gears 7 are respectively rotatably connected to the positioning frame 4 and meshed with the two first racks 6. The two second racks 8 are fixedly connected to the pushing frame 11 at the same time and meshed with the two main gears 7 respectively. During the working stage of the vibrator 5, the sliding seat 10 moves downward under the action of the electric push rod 9. At this time, the two first racks 6 fixedly connected to both sides of the sliding seat 10 move downward accordingly. The two first racks 6 are meshed with the two main gears 7 rotatably connected to the positioning frame 4. The downward movement of the first rack 6 drives the main gear 7 to rotate, and the rotation of the main gear 7 drives the second rack 8 to move upward, so that the pushing frame 11 moves upward, realizing that the screed 20 moves away from the formwork 1, avoiding damage to the screed 20 during the vibration process.

[0044] After the vibrator 5 finishes working and leaves the formwork 1, the electric push rod 9 drives the sliding seat 10 to move upward. The first rack 6 moves upward, the main gear 7 rotates in the reverse direction, and the second rack 8 drives the pushing frame 11 to move downward, making the screed 20 close to the formwork 1 and leveling the upper end of the concrete. The whole process realizes the linkage switching of the working states of the vibrator 5 and the screed 20 through the transmission of the rack and the gear, improving the working efficiency and the automation degree of the device.

[0045] In order to realize the reciprocating movement of the sliding table 18, the following features are specifically set:

[0046] The leveling mechanism 13 further includes a driving motor 14, a screw rod 15, a nut sleeve 16 and two limiting rods 17. The driving motor 14 is fixedly connected to one end of the pushing frame 11. The screw rod 15 is rotatably arranged in the middle of the pushing frame 11 and one end is fixedly connected to the output end of the driving motor 14 coaxially. The nut sleeve 16 is threadedly connected to the screw rod 15. The two limiting rods 17 are arranged on both sides of the screw rod 15 and both ends are fixedly connected to the pushing frame 11. The sliding table 18 is fixedly connected to the nut sleeve 16 and slidably connected to the limiting rods 17 on both sides. When the driving motor 14 is started, the driving motor 14 drives the sliding table 18 to move through the cooperation of the screw rod 15 and the nut sleeve 16. The forward and reverse rotation of the driving motor 14 controls the rotation direction of the screw rod 15, so as to realize the reciprocating movement of the sliding table 18 on the pushing frame 11, driving the connected screed 20 to continuously level the concrete in the formwork 1. And by adjusting parameters such as the rotation speed of the driving motor 14, the moving speed and frequency of the sliding table 18 can be flexibly controlled to meet the leveling requirements under different working conditions.

[0047] In order to realize that when the sliding table 18 moves to both ends of the screw rod 15 each time, the inclination angle of the screed 20 will deflect, so that the screed 20 can level the upper end of the concrete through the arc angle 21 during the movement, the following features are specifically set:

[0048] The leveling mechanism 13 further includes a pushing baffle 28, two deflection frames 22, two pressing rods 12, two power racks 27, two power gears 26, two reversing gears 25, two power pulleys 24 and two deflection pulleys 23. The two deflection frames 22 are respectively fixedly connected to the lower ends of the sliding table 18. The two deflection pulleys 23 are respectively rotatably connected to the two deflection frames 22. The two deflection pulleys 23 are respectively fixedly connected to the screed plate 20. The two power pulleys 24 are respectively arranged above the two deflection pulleys 23 and rotatably connected to the side wall of the sliding table 18. The two reversing gears 25 are respectively coaxially fixedly connected to the two power pulleys 24. The two power gears 26 are respectively arranged above the two reversing gears 25 and meshed with the reversing gears 25. The two power racks 27 are respectively slidably connected to the two sides of the sliding table 18 and meshed with the corresponding power gears 26. The two pushing baffles 28 are respectively arranged at the two ends of the sliding table 18 and fixedly connected to the ends of the power racks 27. The two pressing rods 12 are respectively fixedly connected to the side of the pushing frame 11 close to the sliding table 18. When the sliding table 18 approaches the pressing rod 12, the sliding table 18 will drive the pushing baffle 28 to collide with the pressing rod 12. The pushing baffle 28 is the movable end of the leveling mechanism 13. During the movement of the sliding table 18 along the pushing frame 11, when the sliding table 18 approaches the pressing rod 12, the pushing baffle 28 at the end of the sliding table 18 will collide with the pressing rod 12. As the movable end of the leveling mechanism 13, the movement of the pushing baffle 28 drives the power rack 27 connected thereto to move. The power rack 27 is meshed with the power gear 26, and the rotation of the power gear 26 drives the reversing gear 25 meshed therewith to rotate. The reversing gear 25 drives the power pulley 24 to rotate, and the power pulley 24 drives the screed plate 20 to deflect at an inclined angle through the deflection pulley 23. That is, when the sliding table 18 moves to both ends of the screw rod 15, through the above series of transmission structures, the change of the inclined angle of the screed plate 20 is realized, so that the screed plate 20 can better level the upper end of the concrete through the arc angle 21 during the movement, improving the leveling effect and quality.

[0049] In order to limit the deflected screed plate 20 and prevent the screed plate 20 from self-resetting after the pressing rod 12 and the pushing baffle 28 are separated, the following features are specifically set:

[0050] The leveling mechanism 13 further includes a positioning slide plate 29, a limit short pin 31, a slider 32, a movable magnet block 33 and a positioning magnet block 34. The positioning slide plate 29 is slidably connected to the slide table 18. A V-shaped limit hole 30 is formed in the middle of the positioning slide plate 29. The two ends of the positioning slide plate 29 are fixedly connected to the pushing baffle 28 respectively. A limit groove 19 is formed inside the slide table 18. The slider 32 is slidably connected to the limit groove 19. One end of the limit short pin 31 is fixedly connected to the slider 32, and the other end is slidably connected to the V-shaped limit hole 30. The movable magnet block 33 is fixedly connected to the lower end of the slider 32. The positioning magnet block 34 is arranged below the movable magnet block 33 and is fixedly connected to the slide table 18. When the movable magnet block 33 abuts against the positioning magnet block 34, they are attracted to each other by magnetic force. When the leveling plate 20 deflects, the positioning slide plate 29 moves simultaneously (that is, when the pushing baffle 28 and the touch pressure rod 12 collide, the pushing baffle 28 will drive the positioning slide plate 29 to move). The limit short pin 31 slides in the V-shaped limit hole 30, guiding and limiting the movement of the positioning slide plate 29 (during this process, the limit short pin 31 will move from one end of the V-shaped limit hole 30 to the other end, and correspondingly, the slider 32 will reciprocate along the limit groove 19, that is, the movable magnet block 33 and the positioning magnet block 34 will first separate and then re-adsorb). When the movable magnet block 33 moves to the position where it abuts against the positioning magnet block 34, the two are attracted to each other by magnetic force, fixing the slider 32 at the current position, thereby limiting the deflected leveling plate 20 and preventing the leveling plate 20 from resetting automatically after the touch pressure rod 12 and the pushing baffle 28 separate, ensuring that the leveling plate 20 always maintains an appropriate inclination angle during the leveling process, and improving the stability and reliability of the leveling operation.

[0051] The working principle of this device is as follows. During the casting operation of civil engineering concrete wall panels, first, the wall panel formwork 1 for shaping concrete is accurately placed on the bearing platform 2. At this time, the three-axis moving mechanism 3 is started, and its output end drives the positioning frame 4 fixedly connected thereto to approach the bearing platform 2. The grouting box 36 beside the positioning frame 4 is communicated with the concrete mixer truck tank body, and the transported concrete is stored in advance. The stirring paddle 41 inside the grouting box 36 rotates continuously under the drive of the stirring motor 40, stirring the concrete in the grouting box 36, effectively preventing the concrete from stratifying and precipitating during the waiting for casting process, and ensuring the uniformity and good fluidity of the concrete.

[0052] When the casting is about to be carried out, the deflection motor 39 works, and its output end drives the grouting box 36 to tilt around the connection point of the positioning seat 38. During the tilting process of the grouting box 36, the two-axis motor 42 is started. Through the transmission structure of the belt pulley and the gear rack, the feeding plate 48 moves towards the direction close to the leveling plate 20, and at the same time, the box door 47 moves upward to open the feeding port 37. The concrete in the grouting box 36 smoothly flows into the formwork 1 through the feeding port 37 under the action of gravity, completing the casting operation of the wall panel.

[0053] After pouring is completed, the output end of the vibrator 5 extends downward into the formwork 1 under the action of the electric push rod 9 to vibrate the concrete. During the vibration process, the sliding seat 10 drives the first rack 6 connected thereto to move downward under the action of the electric push rod 9. Through the transmission of the main gear 7 and the second rack 8, the pushing frame 11 moves upward, and the screed board 20 moves away from the formwork 1 to avoid damage to the screed board 20 caused by vibration. After the vibrator 5 works for a period of time to eliminate the air bubbles and gaps in the concrete, then the electric push rod 9 drives the sliding seat 10 to move upward, and the screed board 20 moves downward along with the pushing frame 11 to approach the upper end of the concrete.

[0054] The screeding operation starts. The drive motor 14 drives the screw rod 15 to rotate, so that the screw sleeve 16 drives the sliding table 18 to reciprocate along the limiting rod 17. The sliding table 18 drives the screed board 20 to perform a preliminary screeding of the concrete. When the sliding table 18 moves to both ends of the screw rod 15, the pushing baffle 28 at the end of the sliding table 18 collides with the contact pressure rod 12. Through a series of transmission structures of pulleys, gears and racks, the screed board 20 deflects at an inclined angle, and the arc-shaped corners 21 on both sides of the screed board 20 are used to further perform a fine screeding of the concrete to improve the flatness and smoothness of the concrete surface. After the screed board 20 deflects, the limiting structure composed of the positioning slide plate 29, the limiting short pin 31, the slide block 32, the movable magnetic block 33 and the positioning magnetic block 34 limits the screed board 20 to prevent it from resetting itself and ensures the stable progress of the screeding operation. Through the coordinated work of each mechanism of the whole device, the high-efficiency and high-quality completion of the concrete wall panel pouring operation is realized.
