Description

Technical Field

[0001] This invention belongs to the field of beam and slab casting technology, specifically a casting and placing device and operating method for forming concrete beams and slabs. Background Technology

[0002] With the rapid and large-scale development of prefabricated buildings, municipal bridges, and transportation infrastructure in my country, precast concrete beams and slabs have become core precast components for building structures, bridge paving, and floor load-bearing systems due to their advantages such as high rigidity, strong integrity, high construction efficiency, and low on-site pollution. Under the industry's trend towards large-scale, standardized, and high-quality development, the market has placed more stringent demands on the appearance flatness, dimensional accuracy, structural density, and overall durability of precast concrete beams and slabs. Refined casting and molding processes have become the core key to ensuring the quality of precast beam and slab production. Currently, precast concrete beams and slabs generally adopt an industrialized production model of mold-based casting, where concrete mixture is poured into a precast mold, and after leveling, curing, and demolding, standard beam and slab components are formed.

[0003] However, during the concrete pouring and placement process, irregularly shaped enclosed areas such as the inner corners of the mold are weak points in the pouring process. The concrete's fluidity is limited, making it prone to issues such as insufficient compaction of the slurry. This ultimately leads to defects at the edges and corners of the formed beam and slab components, and makes it difficult to meet the dimensional accuracy standards. Secondly, during the pouring process, the concrete mixture cannot achieve a tight fit with the inner wall of the mold. Air bubbles and voids are easily left on the contact surface between the inner wall of the mold and the concrete. After demolding, the sides of the beam and slab are prone to surface defects such as pitting and unevenness. In addition, after the concrete is poured, when leveling with traditional manual or mechanical scrapers, the excess concrete overflowing from the top of the mold is very easy to stick to the scraper surface and will continue to pile up as the scraper is leveling. This part of the concrete cannot naturally fall back to fill the depressions and pores on the concrete surface, resulting in uneven thickness and local material shortages on the top surface of the beam and slab. This leads to poor surface flatness and inconsistent density of the components after leveling.

[0004] Therefore, the present invention provides a concrete pouring and placing device and operating method for forming concrete beams and slabs. Summary of the Invention

[0005] To address the shortcomings of existing technologies and solve the problems of irregularly shaped enclosed areas such as the inner corners of molds being weak points during pouring, where concrete fluidity is limited and the vibration transmission effect is significantly weakened, easily leading to insufficient grout filling and ultimately resulting in missing edges and corners of the formed beam and slab components, making it difficult to meet dimensional accuracy standards. Secondly, during the pouring process, the concrete mixture cannot achieve a tight fit with the inner wall of the mold, and air bubbles and gaps are easily left on the contact surface between the inner wall of the mold and the concrete. After demolding, the sides of the beam and slab are prone to surface defects such as pitting and unevenness. In addition, after the concrete is poured, during traditional manual or mechanical scraping leveling, excess concrete overflowing from the top surface of the mold easily adheres to the scraper surface and continues to accumulate upwards during the leveling operation. This part of the concrete cannot naturally fall back to fill the depressions and pores on the concrete surface, resulting in uneven thickness and local material shortages on the top surface of the beam and slab, leading to poor surface flatness and inconsistent density of the components after leveling.

[0015] An operating method for a concrete beam and slab forming casting and placing device, applicable to the aforementioned concrete beam and slab forming casting and placing device, the steps of which are as follows:

[0016] S1: Pour concrete into the mold, start the hydraulic cylinder to control the slide plate to move downward, so that the extrusion block is inserted into the concrete, start the second motor to control the extrusion block to move laterally, so that the extrusion block repeatedly squeezes the concrete against the inner wall of the mold.

[0017] S2: After the slide plate moves downward, it drives the extrusion plate to insert into the concrete. The third motor is started to control the first cam to rotate. With the cooperation of the second spring, the concrete under the extrusion plate fills the corner of the bottom of the mold.

[0018] S3: After compacting the concrete inside the mold, start the hydraulic cylinder to retract the slide plate, start the first motor to control the U-shaped frame to move laterally, so that the scraper moves laterally and smooths the excess concrete on the top of the mold.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. The concrete pouring and placing device and operating method for forming concrete beams and slabs according to the present invention control the connecting plate to move laterally via a second motor, which drives two rotating shafts and two gears to move laterally. While the gears move laterally, they cooperate with the rack, causing the gears to rotate while moving laterally, which in turn drives the rotating shafts to rotate while moving laterally, causing the eccentric wheel to rotate. Through the cooperation of the eccentric wheel and the first spring, the extrusion block continuously extrudes concrete against the inner wall of the mold during the lateral movement, helping the concrete to fit tightly against the inner wall of the mold and preventing pitting or unevenness on the sides of the formed beams and slabs. By setting one side of the extrusion block as a symmetrical inclined plane, it is convenient for the extrusion block to move through the concrete.

[0021] 2. The concrete pouring and placing device and operating method for forming concrete beams and slabs according to the present invention, wherein a third motor controls the rotation of a first cam, which, in conjunction with a second spring, causes the extrusion plate to move up and down reciprocally. By installing the extrusion plate at an angle, as the extrusion plate slowly moves upward, the concrete at its top flows down the inclined surface of the extrusion plate to the bottom of the extrusion plate. When the extrusion plate moves downward, the extrusion of the bottom inclined surface of the extrusion plate causes the concrete below the extrusion plate to impact the corner of the bottom of the mold, helping the concrete to fill the inner corner of the mold and preventing the edges and corners of the formed beam and slab components from being damaged. After the sliding plate is controlled to move upward and drive the extrusion plate upward to remove the concrete, the third motor continues to control the rotation of the first cam, causing the two extrusion plates to vibrate downward continuously. This facilitates the shaking of concrete adhering to the outside of the two extrusion plates into the mold, preventing concrete from adhering to the extrusion plates and causing the concrete inside the mold to be missing.

[0022] 3. The concrete pouring and placing device and operating method for forming concrete beams and slabs according to the present invention, by setting one side of the baffle to an arc surface, facilitates the scraper to move to the top of the mold, and the baffle can wrap the concrete adhering to the bottom of the scraper, preventing the concrete from overflowing to both sides during the lateral movement of the scraper. By setting two third springs, the scraper is pressed against the top of the mold. The first motor controls the U-shaped frame to continue to move laterally, so that the scraper continues to move laterally and smooths the excess concrete at the top of the mold. By setting the scraper to an arc shape, the concrete adhering to the bottom of the scraper and accumulating upward can fall along the concave surface of the scraper under the action of gravity.

[0023] 4. The concrete beam and slab forming pouring and placing device and operating method of the present invention, when the concrete surface is found to be missing, the second cam is controlled to rotate by the fourth motor. When the second cam rotates, it cooperates with the third spring to make the scraper vibrate continuously downward, thereby shaking the concrete adhering to the scraper back into the mold to fill the top of the concrete layer and avoid missing material at the top of the concrete layer.

Detailed Implementation

[0036] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0037] like Figures 1 to 10As shown, the present invention provides a technical solution: a concrete beam and slab forming casting and placing device, comprising a base 1, a first motor 3 fixedly connected to one side of the base 1, the output end of the first motor 3 extending into the interior of the base 1 and fixedly connected to a first lead screw 4, the end of the first lead screw 4 being rotatably connected to the base 1, a first slider 5 connected to the outer wall of the first lead screw 4 via a lead screw and nut pair, the first slider 5 being slidably connected to the base 1, a leveling component being provided on the top of the first slider 5, a mold 2 fixedly connected to the top of the base 1, and two side plates 6 symmetrically fixedly connected to the top of the base 1, the tops of the two side plates 6 sharing a common... A support plate 7 is fixedly connected, and four hydraulic cylinders 8 are fixedly connected inside the support plate 7. The output ends of the four hydraulic cylinders 8 are all fixedly connected to a slide plate 9. A second motor 10 is fixedly connected inside the slide plate 9, and a second lead screw 11 is fixedly connected to the output end of the second motor 10. The end of the second lead screw 11 is rotatably connected to the slide plate 9. A second slider 12 is connected to the outer wall of the second lead screw 11 through a lead screw and nut pair. The second slider 12 is slidably connected to the slide plate 9. A pressing assembly is provided at the bottom of the second slider 12. The pressing assembly includes a connecting plate 13, which is fixedly installed at the bottom of the second slider 12. Two brackets 14 are symmetrically fixedly connected to the bottom of the connecting plate 13. A rotating rod 15 is rotatably connected to the inner wall of each bracket 14. An extrusion block 16 is fixedly connected to the bottom of each rotating rod 15. One side of the extrusion block 16 is a symmetrical inclined surface, and the other side is a straight surface. A drive unit is provided at the bottom of the sliding plate 9. The drive unit includes two racks 17, which are symmetrically fixedly installed at the bottom of the sliding plate 9. Two rotating shafts 18 are symmetrically rotatably connected to the bottom of the connecting plate 13. Gears 19 are fixedly connected to the outer wall of each of the two rotating shafts 18. The two gears 19 mesh with the two racks 17 respectively. Eccentric wheels 20 are fixedly connected to the bottom of each of the 8. The eccentric wheels 20 and the rotating rod 15 are used in conjunction with each other. Two fixed plates 21 are symmetrically fixedly connected to the bottom of the connecting plate 13. The inner walls of the two fixed plates 21 are slidably connected to the first sliding shaft 22. One end of the first sliding shaft 22 is fixedly connected to the support block 23. One side of the support block 23 abuts against the outer wall of the rotating rod 15. The other end of the first sliding shaft 22 is fixedly connected to the first limiting block 25. The outer wall of the first sliding shaft 22 is fitted with a first spring 24. One end of the first spring 24 is fixedly connected to the fixed plate 21. The other end of the first spring 24 is fixedly connected to the support block 23.

[0038] Using the above technical solution, concrete is injected into mold 2. Hydraulic cylinder 8 controls the sliding plate 9 to move downwards, causing connecting plate 13 to move downwards. This drives two rotating rods 15 and two extrusion blocks 16 to move downwards and insert into the concrete. The second motor 10 is started, driving the second lead screw 11 to rotate, causing the second slider 12 to move laterally. This, in turn, drives connecting plate 13 to move laterally, causing the two rotating rods 15 and two extrusion blocks 16 to move laterally. Simultaneously, this drives two rotating shafts 18 and two gears 19 to move laterally. When gears 19 move laterally, they engage with rack 17, causing gears 19 to rotate while moving laterally. This rotation drives rotating shafts 18 to rotate while moving laterally, causing eccentric wheel 20 to rotate. When the protruding end of eccentric wheel 20 rotates close to rotating rod 15, it pushes rotating rod 15 to swing to one side, causing extrusion blocks 16 to move to one side. The oscillation mechanism, by setting one side of the extrusion block 16 as a symmetrical inclined plane, facilitates the extrusion block 16 to move within the concrete. After the rotating rod 15 rotates, it pushes the support block 23 to move, compressing the first spring 24. When the protruding end of the eccentric wheel 20 rotates away from the rotating rod 15, it loses the extrusion of the eccentric wheel 20. Under the action of the first spring 24, it drives the rotating rod 15 to swing back, causing the extrusion block 16 to swing back. By setting the other side of the extrusion block 16 as a straight plane, when the extrusion block 16 swings back, it squeezes the concrete in the mold 2 against the inner wall of the mold 2. This process repeats itself. As the connecting plate 13 moves laterally, the extrusion block 16 continuously squeezes the concrete against the inner wall of the mold 2 during the lateral movement, helping the concrete to fit tightly against the inner wall of the mold 2 and preventing pitting or unevenness on the sides of the formed beam slab.

[0039] Specifically, a mounting bracket 26 is fixedly connected to the bottom of the skateboard 9. Two second sliding shafts 27 are symmetrically slidably connected to the inner wall of the mounting bracket 26. Connecting brackets 28 are fixedly connected to both sides of each of the two second sliding shafts 27. Extrusion plates 29 are fixedly connected to the bottom of the two mutually distant connecting brackets 28. Both extrusion plates 29 are installed at an inverted V-shape, tilted outwards from top to bottom. A fabric assembly is provided at the top of the mounting bracket 26. The fabric assembly includes two third motors 35, which are symmetrically fixedly installed at the top of the mounting bracket 26. First cams 36 are fixedly connected to the output ends of both third motors 35. The top of the two sliding shafts 27 are fixedly connected to a first top plate 33. The bottom of the first top plate 33 is symmetrically fixedly connected to two first top blocks 34. The bottom of the first top blocks 34 is set as a symmetrical inclined surface and cooperates with the first cam 36. The outer wall of the second sliding shaft 27 and above the mounting bracket 26 is fixedly connected to a first limiting plate 30. The outer wall of the second sliding shaft 27 and below the mounting bracket 26 is fixedly connected to a second limiting block 31. The outer wall of the second sliding shaft 27 is fitted with a second spring 32. The top of the second spring 32 is fixedly connected to the mounting bracket 26, and the bottom of the second spring 32 is fixedly connected to the second limiting block 31.

[0040] Through the above technical solution, as the slide plate 9 moves downward, it drives the mounting bracket 26 downward, causing the two second sliding shafts 27 to move downward, which in turn drives the two extrusion plates 29 downward and inserts them into the concrete inside the mold 2. The third motor 35 is then activated, causing the first cam 36 to rotate slowly. When the protruding end of the first cam 36 rotates to a position close to the first top block 34, under the pressure of the first cam 36, the first top block 34 is pushed upward slowly, causing the first top plate 33 to move upward slowly. This causes the two second sliding shafts 27 and the two second limiting blocks 31 to move upward slowly, which in turn drives the two extrusion plates 29 to move upward slowly. Simultaneously, as the two extrusion plates 29 move upward slowly, the concrete on their tops moves along the slope of the extrusion plates 29. As the concrete flows to the bottom of the extrusion plate 29, the two second limiting blocks 31 move upward while pressing the two second springs 32. When the protruding end of the first cam 36 rotates to a position away from the first top block 34, it loses the extrusion of the first cam 36. Under the action of the two second springs 32, it pushes the two second limiting blocks 31 downward, causing the two second sliding shafts 27 to move downward, which in turn drives the two extrusion plates 29 to move downward. Through the extrusion of the bottom inclined surface of the extrusion plate 29, the concrete below the extrusion plate 29 impacts the corner of the bottom of the mold 2. This process repeats. As the third motor 35 starts, it drives the extrusion plate 29 to continue to extrude downward, helping the concrete to fill the inner corner of the mold 2 and preventing the corners of the formed beam and slab components from being damaged.

[0041] Specifically, the leveling component includes a U-shaped frame 37, which is mounted on top of the base 1 and slidably connected to it. The top of the first slider 5 is fixedly connected to the U-shaped frame 37. Two third sliding shafts 38 are symmetrically slidably connected to the inner wall of the U-shaped frame 37. A mounting plate 39 is fixedly connected to the bottom of the two third sliding shafts 38. A scraper 40 is fixedly connected to one side of the mounting plate 39. The scraper 40 is arc-shaped. Two baffles 41 are symmetrically fixedly connected to the arc surface at the bottom of the scraper 40. One side of each baffle 41 is arc-shaped. A guide plate 42 is fixedly connected to the side wall of the scraper 40. The guide plate 42 is installed at an angle. A fourth motor 47 is fixedly connected to the top of the third slide shaft 37. A second cam 48 is fixedly connected to the output end of the fourth motor 47. A second top plate 45 is fixedly installed on the top of the two third slide shafts 38. A second top block 46 is fixedly connected to the bottom of the second top plate 45. The bottom of the second top block 46 is set as a symmetrical inclined surface and cooperates with the second cam 48. A second limiting plate 43 is fixedly connected to the outer wall of the third slide shaft 38 and above the U-shaped frame 37. A third spring 44 is sleeved on the outer wall of the third slide shaft 38. The bottom of the third spring 44 is fixedly connected to the mounting plate 39, and the top of the third spring 44 is fixedly connected to the U-shaped frame 37.

[0042] Through the above technical solution, after the concrete inside the mold 2 is compacted, the hydraulic cylinder 8 controls the slide plate 9 to move upward, causing the mounting frame 26 to move upward, which in turn drives the two extrusion plates 29 to move upward. After the two extrusion plates 29 move upward and remove the concrete, the third motor 35 continues to control the first cam 36 to rotate. Similarly, under the action of the two second springs 32, the two extrusion plates 29 continue to vibrate downward, thereby facilitating the shaking of concrete adhering to the outside of the two extrusion plates 29 into the mold 2, preventing concrete from adhering to the extrusion plates 29 and causing the concrete inside the mold 2 to be missing. The first motor 3 is started, driving the first lead screw 4 to rotate, causing the first slider 5 to move laterally, which in turn drives the U-shaped frame 37 to move laterally, causing the scraper to... The scraper 40 moves laterally. When the scraper 40 moves close to the mold 2, the edge of the mold 2 presses against the arc-shaped surface of the baffle 41. Under the pressure of the mold 2, the baffle 41 moves upward, causing the scraper 40 to move upward, which in turn causes the mounting plate 39 to move upward, driving the two third sliding shafts 38 to move upward and pressing the two third springs 44. After the scraper 40 moves to the top of the mold 2, under the action of the two third springs 44, the scraper 40 presses against the top of the mold 2. The first motor 3 controls the U-shaped frame 37 to continue moving laterally, causing the scraper 40 to continue moving laterally, smoothing out the excess concrete on the top of the mold 2. The concrete adheres to the scraper 40 and accumulates upward along it. When observed... When the concrete surface is missing, the fourth motor 47 is activated, driving the second cam 48 to rotate. When the protruding end of the second cam 48 rotates to a position close to the second top block 46, under the pressure of the second cam 48, the second top block 46 is pushed upward, causing the second top plate 45 to move upward, driving the two third sliding shafts 38 and the second limiting plate 43 to move upward, causing the scraper 40 to move upward. Simultaneously, the scraper 40 presses against the two third springs 44. When the protruding end of the second cam 48 rotates to a position away from the second top block 46, the pressure of the second cam 48 is lost, and under the action of the third springs 44, the scraper 40 moves downward. When the scraper 40 strikes the top of the mold 2 downward, it generates a downward... The vibration can shake the concrete adhering to the scraper 40 back into the mold 2 to fill the top of the concrete layer and prevent the top of the concrete layer from being lacking material. The baffle 41 can wrap the concrete adhering to the bottom of the scraper 40 to prevent the concrete from overflowing to both sides during the lateral movement of the scraper 40. After the beam plate formed in the mold 2 is taken out, the first slider 5 is moved back by the first motor 3. When the guide plate 42 on the side wall of the scraper 40 moves close to the mold 2, the edge of the mold 2 presses against the inclined surface of the guide plate 42. Thus, under the pressure of the mold 2, the guide plate 42 moves upward, driving the scraper 40 to move upward, so that the scraper 40 can pass over the mold 2 and reset.

[0043] An operating method for a concrete beam and slab forming casting and placing device, applicable to the aforementioned concrete beam and slab forming casting and placing device, the steps of which are as follows:

[0044] S1: Inject concrete into mold 2, start hydraulic cylinder 8 to control slide plate 9 to move downward, so that extrusion block 16 is inserted into concrete, start second motor 10 to control extrusion block 16 to move laterally, so that extrusion block 16 repeatedly extrudes concrete against the inner wall of mold 2.

[0045] S2: After the slide plate 9 moves downward, it drives the extrusion plate 29 to insert into the concrete. The third motor 35 is started to control the first cam 36 to rotate. With the cooperation of the second spring 32, the concrete below the extrusion plate 29 fills the corner of the bottom of the mold 2.

[0046] S3: After compacting the concrete inside the mold 2, start the hydraulic cylinder 8 to retract the slide plate 9, start the first motor 3 to control the U-shaped frame 37 to move laterally, so that the scraper 40 moves laterally to smooth the excess concrete on the top of the mold 2.

[0047] In use, concrete is poured into mold 2. Hydraulic cylinder 8 controls the sliding plate 9 to move downwards, causing connecting plate 13 to move downwards. This drives two rotating rods 15 and two extrusion blocks 16 to move downwards and insert into the concrete. The second motor 10 is started, driving the second lead screw 11 to rotate, causing the second slider 12 to move laterally. This, in turn, drives connecting plate 13 to move laterally, causing the two rotating rods 15 and two extrusion blocks 16 to move laterally. Simultaneously, this drives two rotating shafts 18 and two gears 19 to move laterally. The gears 19, while moving laterally, engage with rack 17, causing them to rotate. This rotation drives rotating shaft 18 to rotate laterally, causing eccentric wheel 20 to rotate. When the protruding end of eccentric wheel 20 rotates close to rotating rod 15, it pushes rotating rod 15 to one side. The oscillation causes the extrusion block 16 to swing to one side. By setting one side of the extrusion block 16 as a symmetrical inclined surface, it facilitates the movement of the extrusion block 16 within the concrete. After the rotating rod 15 rotates, it pushes the support block 23 to move, compressing the first spring 24. When the protruding end of the eccentric wheel 20 rotates away from the rotating rod 15, it loses the extrusion of the eccentric wheel 20. Under the action of the first spring 24, it drives the rotating rod 15 to swing back, causing the extrusion block 16 to swing back. By setting the other side of the extrusion block 16 as a straight surface, when the extrusion block 16 swings back, it squeezes the concrete in the mold 2 against the inner wall of the mold 2. This process repeats itself. As the connecting plate 13 moves laterally, the extrusion block 16 continuously squeezes the concrete against the inner wall of the mold 2 during the lateral movement, helping the concrete to adhere to the mold. The inner wall of mold 2 fits tightly to prevent pitting or unevenness on the sides of the formed beam. As the sliding plate 9 moves downwards, it drives the mounting bracket 26 downwards, causing the two second sliding shafts 27 to move downwards. This, in turn, causes the two extrusion plates 29 to move downwards and insert into the concrete within mold 2. The third motor 35 is activated, causing the first cam 36 to rotate slowly. When the protruding end of the first cam 36 rotates to a position close to the first top block 34, the extrusion of the first cam 36 pushes the first top block 34 upwards, causing the first top plate 33 to move upwards slowly. This causes the two second sliding shafts 27 and the two second limiting blocks 31 to move upwards slowly, and consequently, the two extrusion plates 29 to move upwards slowly. Simultaneously, the concrete on top of the two extrusion plates 29... Soil flows along the inclined surface of the extrusion plate 29 to its lower part. As the two second limiting blocks 31 move upwards, they simultaneously compress the two second springs 32. When the protruding end of the first cam 36 rotates away from the first top block 34, it loses the compression of the first cam 36. Under the action of the two second springs 32, it pushes the two second limiting blocks 31 downwards, causing the two second sliding shafts 27 to move downwards, which in turn moves the two extrusion plates 29 downwards. Through the compression of the inclined surface at the bottom of the extrusion plate 29, the concrete below the extrusion plate 29 impacts the corner of the bottom of the mold 2. This process repeats. As the third motor 35 starts, it drives the extrusion plate 29 to continuously compress downwards, helping the concrete fill the inner corner of the mold 2 and preventing defects at the edges and corners of the formed beam and slab components.After the concrete inside mold 2 is compacted, the slide plate 9 is moved upward by the hydraulic cylinder 8, causing the mounting frame 26 to move upward, which in turn moves the two extrusion plates 29 upward. After the concrete is removed from the two extrusion plates 29, the first cam 36 is rotated by the third motor 35. Similarly, under the action of the two second springs 32, the two extrusion plates 29 vibrate downward continuously, which helps to shake off the concrete adhering to the outside of the two extrusion plates 29 into the mold 2, preventing concrete from adhering to the extrusion plates 29 and causing the concrete inside the mold 2 to be missing. The first motor 3 is started, which drives the first lead screw 4 to rotate, causing the first slider 5 to move laterally, which in turn moves the U-shaped frame. 37 moves laterally, causing scraper 40 to move laterally. When scraper 40 moves close to mold 2, the edge of mold 2 abuts against the arc-shaped surface of baffle 41. Under the pressure of mold 2, baffle 41 moves upward, causing scraper 40 to move upward, which in turn causes mounting plate 39 to move upward, driving two third sliding shafts 38 upward and pressing two third springs 44. After scraper 40 reaches the top of mold 2, the two third springs 44 press scraper 40 against the top of mold 2. The first motor 3 controls U-shaped frame 37 to continue moving laterally, causing scraper 40 to continue moving laterally, smoothing out excess concrete on the top of mold 2. When concrete adheres to the scraper 40 and accumulates upwards along it, the fourth motor 47 is activated, driving the second cam 48 to rotate. When the protruding end of the second cam 48 rotates to a position close to the second top block 46, the compression of the second cam 48 pushes the second top block 46 upwards, causing the second top plate 45 to move upwards. This, in turn, causes the two third sliding shafts 38 and the second limiting plate 43 to move upwards, thus moving the scraper 40 upwards. Simultaneously, the scraper 40 compresses the two third springs 44. When the protruding end of the second cam 48 rotates to a position away from the second top block 46, the compression of the second cam 48 is lost, and the third springs 44... The scraper 40 moves downwards, and when it impacts the top of the mold 2, it vibrates downwards, causing the concrete adhering to the scraper 40 to fall back into the mold 2, filling the top of the concrete layer and preventing material shortage. After the beam slab is removed from the mold 2, the first slider 5 moves back, controlled by the first motor 3. When the guide plate 42 on the side wall of the scraper 40 moves close to the mold 2, the edge of the mold 2 presses against the inclined surface of the guide plate 42. Under the pressure of the mold 2, the guide plate 42 moves upwards, causing the scraper 40 to move upwards, facilitating its return to its original position after passing over the mold 2.
