Description

Technical Field

[0001] The invention relates to the field of concrete pouring, in particular to a concrete wallboard pouring device for civil engineering. Background Art

[0002] In the field of civil engineering, concrete wall panels are important building components, and their casting quality directly affects the overall structural safety and stability of the building. Traditional concrete wall panel casting devices have many problems in practical applications. First, after the concrete is transported to the construction site, it is easy to segregate and stratify during the process of transferring from the transportation equipment to the casting formwork. Common grouting equipment cannot effectively maintain the uniformity of concrete during the casting process, resulting in uneven quality inside the wall panels after casting and the presence of weak strength areas. Secondly, there are also deficiencies in the vibration process. Some vibration devices are difficult to accurately control the vibration depth and time. Either the vibration is insufficient, so that the bubbles and gaps inside the concrete cannot be completely eliminated, affecting the strength and durability of the wallboard; or the vibration is excessive, causing the concrete aggregate to sink and the cement slurry to float, which also reduces the quality of the wallboard. Moreover, the vibration device and the smoothing device are often independent of each other, and the work connection is not smooth, resulting in low construction efficiency. Furthermore, in terms of leveling operations, the traditional trowel plate has a simple structure and cannot flexibly adjust the angle according to the actual conditions of the concrete surface during the leveling process. For large-area concrete wall panels, it is difficult to ensure the consistency of surface flatness, and problems such as uneven surface strength and shrinkage cracks are prone to occur, affecting the appearance and service life of the wall panels. In addition, the existing pouring device has 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 factor has a greater impact on the pouring quality, making it difficult to ensure that the quality of each concrete wall panel can meet high standards. At the same time, the overall structural design of the equipment is not compact and reasonable enough, and it occupies a large space. In some construction sites with narrow space, its use is greatly restricted. 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.

[0015] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0016] refer to Figures 1 to 8 , a concrete wall panel casting device for civil engineering, comprising a bearing platform 2 for positioning a template 1, and also comprising: A positioning frame 4 is fixedly connected to the output end of the three-axis moving mechanism 3, the positioning frame 4 is arranged beside the bearing platform 2, an electric push rod 9 is fixedly connected to the positioning frame 4 and the output end is arranged downward, a sliding seat 10 is 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 push frame 11 is vertically slidably arranged on the positioning frame 4, the push frame 11 and the sliding seat 10 move in opposite directions, and a smoothing mechanism 13 is arranged on the push frame 11, and 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 by reciprocating movement To smooth the concrete, a grouting mechanism 35 is provided at the bottom of the positioning frame 4. The grouting mechanism 35 includes a grouting box 36 which is connected to the tank body of the concrete mixer truck and can be tilted. A feeding port 37 is formed at the lower part of the grouting box 36 on the side close to the trowel plate 20. A box door 47 is slidably provided on the side of the grouting box 36 close to the feeding port 37. A stirring paddle 41 is rotatably provided 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 provided at the bottom of the grouting box 36. When the grouting box 36 is tilted, the feeding plate 48 moves toward the direction close to the trowel plate 20 and the box door 47 moves upward.

[0017] When the device is in operation, the wall panel formwork 1 for shaping concrete is placed on the supporting platform 2, and then the three-axis moving mechanism 3 drives the positioning frame 4 to approach the supporting platform 2. At this time, the grouting box 36 temporarily stores the concrete transported by the concrete mixer truck, and the stirring paddle 41 stirs the concrete in the grouting box 36 to prevent the concrete from being stratified in the grouting box 36. Then, 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 toward the direction close to the trowel plate 20 to guide 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.

[0018] After pouring is completed, the output end of the vibrator 5 is extended into the template 1 to vibrate the concrete to eliminate the bubbles and gaps in the concrete. After the vibration is completed, as the output end of the vibrator 5 leaves the concrete, the trowel plate 20 moves downward and approaches the upper end of the concrete. Then, under the action of the smoothing mechanism 13, the trowel plate 20 smoothes the concrete to avoid problems such as uneven strength and shrinkage cracks on the surface, thereby ensuring the consistency and stability of the overall performance of the concrete.

[0019] In order to achieve the tilting of the grouting box 36 and the driving of the stirring paddle 41 so that the concrete in the grouting box 36 can be poured into the template 1, the following features are also specifically provided: The grouting mechanism 35 also 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, which is convenient for pouring the internal concrete into the template 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 is working, it drives the stirring paddle 41 to rotate at a high speed inside the grouting box 36 to continuously stir the concrete, prevent the concrete from being layered, precipitated, etc. in the process of waiting for pouring, ensure the uniformity and fluidity of the concrete, and provide guarantee for high-quality pouring operations.

[0020] In order to achieve that when the feeding plate 48 moves toward the direction close to the trowel plate 20, the box door 47 moves upward, the following features are specifically provided: The grouting mechanism 35 also includes a dual-axis motor 42, two assembly pulleys 43, four secondary pulleys 44, four secondary gears 45 and four secondary racks 46. The dual-axis motor 42 is fixedly connected to the grouting box 36. The two assembly pulleys 43 are coaxially fixedly connected to the two output ends of the dual-axis motor 42. Two secondary pulleys 44 are respectively arranged on the sides of each assembly pulley 43. The two secondary pulleys 44 are respectively rotatably connected to the side walls of the grouting box 36 and are transmission-connected to the corresponding assembly pulleys 43 through belts. The four secondary gears 45 are respectively coaxially fixedly connected to the four secondary pulleys 44. A secondary rack 46 is respectively fixedly connected to both sides of the box door 47 and the feeding plate 48, and the secondary rack 46 is meshed with the corresponding secondary gear 45. When the dual-axis motor 42 is started, the dual-axis motor 42 will drive the corresponding secondary pulley 44 to rotate through the assembly pulley 43. After the secondary pulley 44 rotates, it will drive the secondary rack 46 to move through the secondary gear 45. The movement of the secondary rack 46 can make the feed plate 48 move toward the trowel plate 20, and at the same time drive the box door 47 to move upward, so as to realize the opening of the feed port 37, so as to facilitate the smooth flow of concrete in the grouting box 36 for pouring operations, and the moving speed and position of the feed plate 48 and the box door 47 can be flexibly controlled as needed during the pouring process.

[0021] In order to facilitate the trowel plate 20 to smooth the concrete in the template 1 during the movement, the following features are also specifically provided: The trowel plate 20 has curved corners 21 formed on both sides thereof, and the trowel plate 20 smoothes the concrete in the formwork 1 through the curved corners 21. When the trowel plate 20 is close to the concrete in the formwork 1, the curved corners 21 first contact the concrete surface. The curved corners 21 allow the concrete to be more evenly distributed on the surface of the formwork 1 during the squeezing and pushing process, filling the tiny depressions and gaps on the surface, thereby achieving efficient smoothing of the concrete. Compared with an ordinary straight trowel plate 20, the trowel plate 20 with curved corners 21 can better adapt to the unevenness of the concrete surface, reduce scratches, accumulation and other problems on the concrete surface, and effectively improve the flatness and finish of the concrete surface.

[0022] In order to realize that when the vibrator 5 is inserted into the template 1 to vibrate the concrete, the trowel plate 20 is away from the template 1; and when the vibrator 5 leaves the template 1, the trowel plate 20 is close to the template 1 and smoothes the upper end of the concrete in the template 1, the following features are specifically provided: The device also includes two first racks 6, two main gears 7 and two second racks 8. The two first racks 6 are respectively fixedly connected to the two 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 simultaneously fixedly connected to the push frame 11 and meshed with the two main gears 7. 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 the two sides of the sliding seat 10 move downward accordingly. The two first racks 6 mesh with the two main gears 7 rotatably connected to the positioning frame 4. The downward movement of the first racks 6 drives the main gears 7 to rotate. The rotation of the main gears 7 drives the second racks 8 to move upward, so that the push frame 11 moves upward, so that the trowel plate 20 is away from the template 1, and damage to the trowel plate 20 is avoided during the vibration process.

[0023] When the vibrator 5 finishes its work and leaves the template 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 opposite direction, and the second rack 8 drives the pushing frame 11 to move downward, so that the trowel plate 20 approaches the template 1 and smoothes the upper end of the concrete. The whole process realizes the linkage switching of the working status of the vibrator 5 and the trowel plate 20 through the transmission of the rack and gear, thereby improving the working efficiency and the degree of automation of the device.

[0024] In order to realize the reciprocating movement of the slide 18, the following features are also specifically provided: The smoothing mechanism 13 also includes a driving motor 14, a screw 15, a screw sleeve 16 and two limit rods 17. The driving motor 14 is fixedly connected to one end of the push frame 11. The screw 15 is rotatably arranged in the middle of the push frame 11 and one end is coaxially fixedly connected to the output end of the driving motor 14. The screw sleeve 16 is threadedly connected to the screw 15. The two limit rods 17 are arranged on both sides of the screw 15 and both ends are respectively fixedly connected to the push frame 11. The slide 18 is fixedly connected to the screw sleeve 16 and both sides are slidably connected to the limit rods 17 respectively. When the drive motor 14 is started, the drive motor 14 will drive the slide 18 to move through the cooperation of the screw 15 and the screw sleeve 16. The drive motor 14 controls the rotation direction of the screw 15 by forward and reverse rotation, thereby realizing the reciprocating movement of the slide 18 on the push frame 11, driving the trowel plate 20 connected thereto to continuously smooth the concrete in the template 1, and by adjusting parameters such as the rotation speed of the drive motor 14, the moving speed and frequency of the slide 18 can be flexibly controlled to meet the smoothing requirements under different working conditions.

[0025] In order to achieve that each time the slide 18 moves to the two ends of the screw 15, the inclination angle of the trowel plate 20 will deflect, so that the trowel plate 20 can smooth the upper end of the concrete through the arc angle 21 during the movement, the following features are also specifically set: The smoothing mechanism 13 also includes a push baffle 28, two deflection frames 22, two contact pressure 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 end of the slide 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 trowel plate 20, the two power pulleys 24 are respectively arranged above the two deflection pulleys 23 and are rotatably connected to the side walls of the slide 18, and the two reversing gears 25 are respectively connected to the two power pulleys. The wheels 24 are coaxially fixed, the two power gears 26 are respectively arranged on the upper sides of 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 slide 18 and meshed with the corresponding power gears 26, the two push baffles 28 are respectively arranged at the two ends of the slide 18 and are fixedly connected to the ends of the power racks 27, the two touch-pressure rods 12 are respectively fixedly connected to the side of the push frame 11 close to the slide 18, the slide 18 will drive the push baffle 28 to collide with the touch-pressure rod 12 when it approaches the touch-pressure rod 12, and the push baffle 28 is the movable end of the smoothing mechanism 13. When the slide 18 moves along the slide frame 11, when the slide 18 approaches the touch-pressure rod 12, the push baffle 28 at the end of the slide 18 will collide with the touch-pressure rod 12. The push baffle 28 is the movable end of the smoothing mechanism 13, and its movement 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 in turn drives the power pulley 24 to rotate, and the power pulley 24 drives the trowel plate 20 to deflect at an inclination angle through the deflection pulley 23. That is, when the slide 18 moves to both ends of the screw 15, the inclination angle of the trowel plate 20 is changed through the above series of transmission structures, so that the trowel plate 20 can better smooth the upper end of the concrete through the arc angle 21 during the movement, thereby improving the smoothing effect and quality.

[0026] In order to limit the deflected trowel plate 20 and prevent the trowel plate 20 from resetting itself after the contact pressure rod 12 and the push baffle plate 28 are separated, the following features are also provided: The smoothing mechanism 13 also includes a positioning slide 29, a limiting short pin 31, a slider 32, a movable magnetic block 33 and a positioning magnetic block 34. The positioning slide 29 is slidably connected to the slide 18. A V-shaped limiting hole 30 is formed in the middle of the positioning slide 29. Both ends of the positioning slide 29 are respectively fixedly connected to the push baffle 28. A limiting groove 19 is formed inside the slide 18. The slider 32 is slidably connected to the limiting groove 19. One end of the limiting short pin 31 is fixedly connected to the slider 32, and the other end is slidably connected to the V-shaped limiting hole 30. The movable magnetic block 33 is fixedly connected to the lower end of the slider 32. The positioning magnetic block 34 is arranged below the movable magnetic block 33 and is fixedly connected to the slide 18. When the movable magnetic block 33 is against the positioning magnetic block 34, it is attracted to the positioning magnetic block 34 by magnetic force. When the trowel plate 20 deflects, the positioning slide plate 29 moves at the same time (that is, when the push baffle plate 28 collides with the pressure rod 12, the push baffle plate 28 will drive the positioning slide plate 29 to move), and the limiting short pin 31 slides in the V-shaped limiting hole 30, guiding and limiting the movement of the positioning slide plate 29 (and in this process, the limiting short pin 31 will move from one end of the V-shaped limiting hole 30 to the other end, and the corresponding slider 32 will reciprocate along the limiting groove 19, that is, the movable magnetic block 33 and the positioning magnetic block 34 will first separate and then re-adsorb). When the movable magnetic block 33 moves to the position against the positioning magnetic block 34, the two are attracted by magnetic force to fix the slider 32 at the current position, thereby limiting the deflected trowel plate 20, preventing the trowel plate 20 from resetting itself after the pressure rod 12 and the push baffle plate 28 are separated, ensuring that the trowel plate 20 always maintains a suitable tilt angle during the troweling process, and improving the stability and reliability of the troweling operation.

[0027] The working principle of this device is that in the pouring operation of concrete wall panels in civil engineering, the device first accurately places the wall panel template 1 used to shape the concrete on the supporting platform 2. At this time, the three-axis moving mechanism 3 is started, and its output end drives the positioning frame 4 fixed to it to approach the supporting platform 2. The grouting box 36 next to the positioning frame 4 is connected to the tank body of the concrete mixer truck to store the transported concrete in advance. The stirring paddle 41 inside the grouting box 36 rotates continuously under the drive of the stirring motor 40 to stir the concrete in the grouting box 36, effectively preventing the concrete from stratification, sedimentation, etc. during the pouring process, and ensuring the uniformity and good fluidity of the concrete. When pouring is ready, 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 dual-axis motor 42 is started, and the feeding plate 48 moves toward the direction close to the trowel plate 20 through the transmission structure of the pulley and the gear rack. At the same time, the box door 47 moves upward to open the feeding port 37. The concrete in the grouting box 36 flows smoothly into the template 1 through the feeding port 37 under the action of gravity, completing the pouring operation of the wall panel. After pouring is completed, the output end of the vibrator 5 extends downward into the template 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 to it to move downward under the action of the electric push rod 9, and the push frame 11 moves upward through the transmission of the main gear 7 and the second rack 8, and the trowel plate 20 is moved away from the template 1 to avoid damage to the trowel plate 20 caused by vibration. After the vibrator 5 works for a period of time, the bubbles and gaps in the concrete are eliminated, and then the electric push rod 9 drives the sliding seat 10 to move upward, and the trowel plate 20 moves downward with the push frame 11 to approach the upper end of the concrete. When the smoothing operation begins, the driving motor 14 drives the screw 15 to rotate, so that the screw sleeve 16 drives the slide 18 to move back and forth along the limit rod 17, and the slide 18 drives the trowel plate 20 to perform preliminary smoothing on the concrete. When the slide 18 moves to both ends of the screw 15, the push baffle 28 at the end of the slide 18 collides with the touch pressure rod 12, and through a series of transmission structures of pulleys, gears and racks, the trowel plate 20 is deflected at an inclined angle, and the arc angles 21 on both sides of the trowel plate 20 are used to further finely smooth the concrete, thereby improving the flatness and finish of the concrete surface. After the trowel plate 20 is deflected, the limiting structure composed of the positioning slide 29, the limiting short pin 31, the slider 32, the movable magnetic block 33 and the positioning magnetic block 34 limits the trowel plate 20 to prevent it from resetting itself, thereby ensuring the stable smoothing operation. The entire device achieves efficient and high-quality completion of the concrete wallboard pouring operation through the coordinated work between various mechanisms.
