Description

Technical Field

[0001] The present invention relates to the field of prefabricated concrete parts production, and in particular to a prefabricated concrete parts processing and conveying system. Background Art

[0002] Prefabricated buildings refer to buildings that are made by transporting prefabricated reinforced concrete parts and accessories prepared in a factory to a construction site and then assembling and installing them on site through reliable connection methods. They have the advantages of high construction efficiency, low labor intensity, and low environmental pollution, and have been widely used.

[0003] In the production process of small concrete precast parts, the concrete raw materials are first distributed into the mold through the distribution mechanism. After completion, the surface needs to be smoothed and finally dried and solidified. The smoothing operation directly determines the surface quality of the concrete precast parts. Currently, there is still manual participation in the smoothing operation. For example, when the concrete slurry is mixed and spread unevenly, manual adjustment is required, which leads to slow production speed and difficult to control the smoothing quality. Some machines are also used for automatic smoothing, but the existing machines often have poor smoothing effects and uneven surfaces. Therefore, it is necessary to provide a concrete precast part processing equipment with good smoothing effect and convenient operation. Summary of the Invention

[0004] The present invention aims to provide a prefabricated concrete part processing and conveying system, so as to provide a prefabricated concrete part processing equipment with good leveling effect and convenient operation.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical solution: a concrete precast part processing and conveying system, including a support frame and a trowel mechanism, the trowel mechanism is slidably arranged on the support frame, the trowel mechanism includes a lifting part and a trowel part, the trowel part is connected to the support frame through the lifting part, the trowel part includes a trowel plate, the trowel plate and the lifting part can rotate relative to each other, and the two sides of the trowel plate can respectively contact the concrete and smooth its surface through rotation, and a rotating roller is also rotatably provided on the trowel plate, and a plurality of rotating disks are coaxially provided on the rotating roller. When the trowel plate rotates to be parallel to the concrete surface, the rotating disk can contact the concrete.

[0006] The beneficial effects of this program are:

[0007] When producing slab-shaped precast concrete parts, a mixed concrete slurry is usually poured into a mold and smoothed using a tool. In this technical solution, a smoothing plate is provided. The two sides of the smoothing plate can respectively contact the concrete and smooth its surface by rotating. When smoothing the concrete surface, the angle of the smoothing plate is adjusted so that it starts to slide from one side of the mold to smooth the concrete surface. When it slides to the other side of the mold, the angle of the smoothing plate is rotated so that the other side of the plate contacts the concrete surface and begins to slide in the opposite direction to smooth it. Generally, in order to process precast concrete plates of different depths and to facilitate repeated use of the mold, the height of the mold is generally higher than the height of conventionally processed plates. Generally, when the scraper slides obliquely from one side to the other, concrete material often accumulates under the scraper, resulting in an uneven surface of the processed precast concrete part. The smoothing plate angle of the present technical solution is adjustable. When the smoothing plate slides to the end of the mold, the smoothing plate is rotated so that the smoothing plate contacts the concrete surface without dead angles. When it slides in the opposite direction, it can smooth the concrete material accumulated on the previous side, making the concrete surface smoother.

[0008] The trowel plate is also equipped with a rotating roller, and multiple rotating disks are coaxially arranged on the rotating roller. When the trowel plate rotates to be parallel to the concrete surface, the rotating disk can contact the concrete. By setting multiple rotating disks in contact with the concrete surface, the concrete can be pre-leveled. Some concrete materials have poor fluidity and often cannot be evenly leveled in the mold, resulting in gaps in the corners of the mold, affecting the strength and quality of the product. The conventional vibration leveling method will cause uneven distribution of coarse and fine aggregates inside the prefabricated part. Therefore, the setting of the rotating disk can pre-level the concrete before leveling, so that the concrete is evenly distributed in the mold, ensuring the quality of the subsequent leveling. The above setting is used to perform surface leveling operations on the mold that has been filled with concrete, realizing the automation of the leveling operation and improving the leveling quality.

[0009] Preferably, as an improvement, the trowel plate includes a straight plate portion and curved plates symmetrically arranged at both ends of the straight plate portion, the curved plates can respectively contact the concrete surface, and the trowel plate is provided with an opening through which the rotating disk passes.

[0010] The beneficial effects are: the contact between the curved plate and the concrete surface is line contact, which can reduce resistance during the leveling process and make the trowel plate slide more smoothly. On the other hand, it can make the concrete surface smoother. In addition, the curved plate can avoid the material accumulation phenomenon caused by traditional straight plates during the leveling process to a certain extent, especially at the edge of the plate, which helps to maintain the uniformity and flatness of the surface of the prefabricated part.

[0011] Preferably, as an improvement, the lifting part includes a connecting rod and two telescopic rods, the connecting rod is used to connect the two telescopic rods, and fan-shaped plates connected to the polishing plate are provided on both sides of the length direction of the polishing plate, and one fan-shaped plate is hinged to a telescopic rod respectively, and a rotating gear is fixed on the fan-shaped plate. The telescopic rods are provided with a first motor and a first gear meshing with the rotating gear, and the first motor realizes the adjustment of the rotation angle of the polishing plate by driving the first gear to rotate.

[0012] The beneficial effects are as follows: the above-mentioned configuration allows the trowel plate to be flexibly adjusted at different angles to accommodate precast concrete parts of varying thicknesses and shapes. By varying the angle of the sector plate, the trowel plate can better conform to the concrete surface. The first motor drives the engagement of the first gear with the rotating gear, enabling precise control of the trowel plate angle. The combination of angle control by the first motor and bilateral adjustment allows the trowel plate to distribute pressure more evenly, ensuring a smoothing effect and a more even surface for the precast part. The provision of a telescopic rod enables processing of concrete parts of varying thicknesses, ensuring both precision and stability of adjustment and making the troweling process more controllable.

[0013] Preferably, as an improvement, sliding pressure roller portions are provided on both sides of the length direction of the trowel plate, and the pressure roller portions include a sleeve, a first spring and a pressure roller fixed at the end of the sleeve, the cross-section of the pressure roller is trapezoidal and the pressure roller on one side close to the trowel plate is smaller in diameter than the other end, a slide plate is provided on the sleeve, and reinforcing plates are fixed on both sides of the trowel plate, and the two ends of the first spring are respectively against the reinforcing plate and the slide plate.

[0014] The beneficial effect is as follows: by setting the first spring, the pressure rollers on both sides can be close to the molds on both sides. When the pressure rollers are in contact with the concrete surface under the drive of the trowel plate, the cross-section of the pressure rollers is trapezoidal and the pressure roller on the side close to the trowel plate is smaller in diameter than the other end, which can push the concrete on the edge to the middle of the mold. The traditional integrated scraper has certain problems. When the scraper is used for troweling in the later stage, the concrete in the middle often flows to both sides. If multiple troweling operations are performed, the concrete materials on both sides will accumulate above the scraper, resulting in waste. The above setting helps to reduce the lateral accumulation of concrete and ensure the uniform distribution of concrete in the mold; the reinforcement plate helps to strengthen the structural strength of the trowel plate; the first spring structure enables the pressure rollers on both sides to be close to the molds on both sides, and at the same time can tension the trowel plate in the mold so that the trowel plate is parallel to the mold in the length direction to prevent it from tilting to one side, which helps to ensure that the two ends of the trowel plate are level during the troweling operation and improve the troweling effect.

[0015] Preferably, as an improvement, a second motor for driving the rotating roller to rotate is provided on the trowel plate, and friction teeth are also provided on the rotating disk.

[0016] The beneficial effects are: some prefabricated concrete parts require a rough surface to ensure the stability of their fixation with other parts through cement. By setting friction teeth, the surface of semi-dry prefabricated concrete parts can be roughened to increase the roughness of the surface, thereby improving its adhesion to other structural parts or coating materials. This technical solution system can not only achieve smooth surface finishing of concrete, but also achieve different degrees of surface roughening by adjusting operating conditions such as the depth of friction teeth, rotation speed, etc., to meet the needs of different application scenarios.

[0017] Preferably, as an improvement, pressure sensors are provided on both sides of the trowel plate in the width direction.

[0018] The beneficial effect is that when one side of the trowel plate contacts the mold, it can be sensed in time and the angle of the trowel plate can be adjusted.

[0019] Preferably, as an improvement, a shock absorbing portion is provided on one side of the trowel plate, and the shock absorbing portion includes a plurality of telescopic shock absorbers, and the two ends of the telescopic shock absorbers are hinged to the trowel plate and the bottom of the telescopic rod respectively.

[0020] The beneficial effects are: the design of the telescopic shock absorber enables the trowel plate to absorb and cushion the vibrations and impacts generated during the troweling process, helping to reduce the instability of the trowel plate caused by fluctuations when the trowel plate contacts the concrete surface, thereby improving the smoothness of the surface trowel; through the cushioning effect of the shock absorber, the trowel plate can run more smoothly, reducing surface defects and unevenness, and improving the surface quality of precast concrete parts.

[0021] Preferably, as an improvement, a support plate supporting the connecting rod is fixed on the support frame, and at least one slide groove is provided on the support plate. A chain driving the connecting rod to slide back and forth is provided in the slide groove, and a self-cleaning block for cleaning the slide groove is also provided on the chain.

[0022] The beneficial effect is that the support plate is fixed to the support frame, providing stable support for the connecting rod and the trowel mechanism below it. This ensures that the trowel mechanism remains stable during operation and reduces vibration and error in its movement.

[0023] Preferably, as an improvement, the self-cleaning block includes a sliding plate and a plurality of supporting legs provided on the sliding plate, the supporting legs are clamped with the chain, the bottom surface of the sliding plate fits with the bottom surface of the slide groove, and the two side surfaces of the sliding plate fit with the side walls on both sides of the slide groove respectively.

[0024] The beneficial effect is: in order to ensure the smooth operation of the chain, it is often necessary to add lubricating oil to the chain. However, there is a lot of dust in the concrete processing workshop, which is easy to accumulate in the chute to form silt, affecting the rotation of the chain and hindering subsequent cleaning. In this technical solution, the silt accumulated in the chute is removed by setting a sliding plate to slide back and forth under the drive of the chain, so as to achieve the cleaning effect of the chute without disassembling the chain. Finally, the two ends of the chute can be opened and cleaned regularly. The sliding plate fits the bottom and side walls of the chute. While improving the silt removal effect, the fitted sliding plate interacts with the chute. Under the connection of the vertically fixed support legs, it plays a role of limiting support for the moving chain, thereby improving the stability of the chain operation, reducing the vibration of the chain, and achieving smooth sliding of the polishing mechanism.

[0025] Preferably, as an improvement, a limit block is provided on the surface of the connecting rod opposite to the slide groove, and the limit block can be inserted into the slide groove.

[0026] The beneficial effect is that the limit block plays a guiding role, restricting the connecting rod from always sliding along the slide groove, thereby ensuring the accuracy of the reciprocating sliding of the connecting rod and the polishing mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following is further described in detail through specific implementation methods:

[0036] The figure marks in the drawings of the specification include: straight plate part 1, curved plate 2, opening 3, connecting rod 4, telescopic rod 5, fan-shaped plate 6, rotating gear 7, first motor 8, first gear 9, collar 10, first spring 11, pressure roller 12, slide plate 13, reinforcing plate 14, second motor 15, rotating roller 16, telescopic damping rod 17, second spring 18, support plate 19, slide 20, chain 21, sliding plate 22, support leg 23, rotating disk 24, self-cleaning block 25, mold 26.

[0037] Example 1

[0038] The embodiment is basically as follows Figure 1-Figure 5 As shown, Figure 1 and Figure 2 The illustrated system for processing and conveying precast concrete parts includes a support frame and a trowel mechanism. The trowel mechanism is slidably mounted on the support frame. The trowel mechanism includes a lifting portion and a trowel unit, which is connected to the support frame via the lifting portion. The trowel unit includes a trowel plate, which is rotatable relative to the lifting portion. The trowel plate rotates relative to the lifting portion. The two sides of the trowel plate contact the concrete and smooth the surface. When smoothing the concrete surface, the trowel plate is angled so that it begins sliding from one side of a mold 26 to smooth the concrete surface. When it reaches the other side of the mold 26, the trowel plate is angled so that the other side of the trowel contacts the concrete surface and begins sliding in the opposite direction to smooth the concrete surface. The trowel plate also rotatably mounts a rotating roller 16. A plurality of rotating disks 24 are coaxially mounted on the rotating roller 16. The rotating roller 16 is keyed to each rotating disk 24. A second motor 15 is provided on the trowel plate to drive the rotating roller 16. Specifically, a sprocket is mounted on the output end of the second motor 15. A sprocket is also fixed to the surface of the rotating roller 16. A sprocket is mounted on the two sprockets. The rotating disk 24 is also equipped with friction teeth. By setting up multiple rotating disks 24 to roll over the concrete surface, the concrete can be pre-flattened. The gaps between the rotating disks 24 allow the concrete material to flow, causing it to flow and be flattened within the mold 26. Some precast concrete parts require a rough surface to ensure the stability of their cement fixation with other components. The friction teeth can be used to roughen the surface of the semi-dry precast concrete parts when the trowel plate slides horizontally, increasing its surface roughness and thus improving its adhesion to other structural parts or coating materials. This technical solution system not only achieves a smooth surface finish for concrete, but also can achieve different degrees of surface roughness by adjusting operating conditions such as the depth of the friction teeth and the rotation speed to meet the needs of different application scenarios.

[0039] The lifting part includes a connecting rod 4 and two telescopic rods 5. The connecting rod 4 is used to connect the two telescopic rods 5. Both sides of the trowel plate in the length direction are provided with fan-shaped plates 6 connected to the trowel plate. A fan-shaped plate 6 is hinged to a telescopic rod 5 respectively. A rotating gear 7 is fixed on the fan-shaped plate 6. Figure 3As shown, the telescopic rod 5 is provided with a first motor 8 and a first gear 9 meshing with the rotating gear 7. The first motor 8 drives the first gear 9 to rotate, and the first gear 9 meshes with the rotating gear 7 to adjust the rotation angle of the trowel plate. This allows the trowel plate to be flexibly adjusted at different angles to accommodate concrete precast parts of different thicknesses and shapes. By changing the angle of the sector plate 6, the trowel plate can better conform to the concrete surface. The first motor 8 drives the first gear 9 to mesh with the rotating gear 7, allowing precise control of the trowel plate angle. Through the first motor 8's angle control and bilateral adjustment, the trowel plate can distribute pressure more evenly, ensuring a smoothing effect and a smoother surface for the precast part. The provision of the telescopic rod 5 enables processing of concrete parts of different thicknesses, ensuring the accuracy and stability of the adjustment, and making the trowel process more controllable. The trowel plate includes a straight plate portion 1 and curved plates 2 symmetrically arranged at both ends of the straight plate portion 1. The curved plates 2 can contact the concrete surface respectively. The contact between the curved plates 2 and the concrete surface is line contact. On the one hand, it can reduce resistance during the leveling process and make the trowel plate slide more smoothly. On the other hand, it can make the concrete surface smoother. In addition, the curved plates 2 can avoid the material accumulation phenomenon caused by traditional straight plates during the leveling process to a certain extent, especially at the edges of the plates, which helps to maintain the uniformity and flatness of the surface of the prefabricated part; the trowel plate is provided with an opening 3 through which the rotating disk 24 passes.

[0040] Sliding pressure rollers are provided on both sides of the length direction of the troweling board. The pressure rollers include a sleeve 10, a first spring 11 and a pressure roller 12 fixed to the end of the sleeve 10. The cross-section of the pressure roller 12 is trapezoidal and the pressure roller 12 close to one side of the troweling board is smaller in diameter than the other end. A slide plate 13 is fixedly connected to the sleeve 10. The sleeve 10 is slidingly connected to the rotating roller 16 and fixedly connected to the slide plate 13. The slide plate 13 is slidingly connected to the troweling board. The arc plates 2 on both sides of the troweling board are worn to a certain extent. The two arc plates 2 may be deformed by force during the smearing process. The distance between the two arc plates 2 will become shorter during troweling. At this time, the slide plate 13 cannot slide smoothly. Through the above arrangement, the deformation can be detected and the troweling board can be replaced to ensure the quality of troweling. Reinforcement plates 14 are welded and fixed on both sides of the trowel plate, which helps to strengthen the structural strength of the trowel plate and improve the trowel effect; the two ends of the first spring 11 are respectively against the reinforcement plate 14 and the slide plate 13, and under the action of the first spring 11, the pressure rollers 12 on both sides can be close to the molds 26 on both sides. When the pressure rollers 12 are driven by the trowel plate to contact the concrete surface, the cross-section of the pressure rollers 12 is trapezoidal and the pressure roller 12 on the side close to the trowel plate is smaller than the diameter of the other end, which can push the edge of the concrete to the middle of the mold 26. The problems of the traditional one-piece scraper are that in the later scraping When troweling, concrete in the middle often flows to the sides. Repeated troweling can cause concrete to accumulate on both sides above the scraper, resulting in waste. This arrangement helps reduce lateral concrete accumulation and ensures uniform distribution within mold 26. The first spring 11 allows the pressure rollers 12 on both sides to adhere closely to the mold 26. It also tensions the trowel plate within the mold 26, keeping it parallel to the mold 26 along its length and preventing it from tilting to one side. This helps ensure both ends of the trowel plate are level during troweling, improving the troweling effect. In this embodiment, the ends of the rotating roller 16 pass through the sector plates 6 on both sides and are inserted into the collars 10 on both sides.

[0041] A support plate 19 is fixed on the support frame to support the connecting rod 4. The support plate 19 is fixed on the support frame to provide stable support for the connecting rod 4 and the polishing mechanism below it. At least one slide groove 20 is opened on the support plate 19, which is one in this embodiment. Figure 4 and Figure 5As shown, a chain 21 is provided in the slide 20 for driving the connecting rod 4 to slide back and forth, and a self-cleaning block 25 is also provided on the chain 21 for cleaning the slide 20; the self-cleaning block 25 in this embodiment includes a sliding plate 22 and a plurality of support legs 23 provided on the sliding plate 22, the support legs 23 are clamped and welded to the chain 21, and the upper ends of the support legs 23 are fixedly connected to the connecting rod 4. The support legs 23 and the sliding plate 22 in this embodiment are welded and made of steel. The bottom surface of the sliding plate 22 is in contact with the bottom surface of the slide 20, and the two side surfaces of the sliding plate 22 are respectively in contact with the side walls on both sides of the slide 20. In order to ensure the smooth operation of the chain 21, it is often necessary to add lubricating oil to the chain 21. However, there is a lot of dust in the concrete processing workshop, which is easy to accumulate in the chute 20 to form silt, affecting the rotation of the chain 21 and hindering subsequent cleaning. In this technical solution, a sliding plate 22 is set to slide back and forth under the drive of the chain 21 to remove the silt accumulated in the chute 20, so as to achieve the cleaning effect of the chute 20 without disassembling the chain 21. Finally, the two ends of the chute 20 can be opened and cleaned regularly. The sliding plate 22 is fitted with the bottom and side walls of the chute 20. While improving the silt removal effect, the fitted sliding plate 22 interacts with the chute 20. Under the connection of the vertically fixed support legs 23, it plays a role of limiting support for the moving chain 21, thereby improving the stability of the chain 21 and reducing the vibration of the chain 21, so as to achieve smooth sliding of the polishing mechanism.

[0042] The specific implementation process is as follows:

[0043] When producing plate-shaped concrete prefabricated parts, the mixed concrete slurry is usually poured into the mold 26 and smoothed with a tool. In this technical solution, a smoothing plate is provided. The two sides of the smoothing plate can respectively contact the concrete and smooth its surface by rotating. When smoothing the concrete surface, the angle of the smoothing plate is adjusted so that it starts to slide from one side of the mold 26 to smooth the concrete surface. When it slides to the other side of the mold 26, the angle of the smoothing plate is rotated so that the other side of the smoothing plate contacts the concrete surface and starts to slide in the opposite direction to smooth it. Generally speaking, in order to process different depths Concrete prefabricated panels, in order to facilitate the repeated use of the mold 26, the height of the mold 26 is generally higher than the height of conventionally processed panels. Generally, when the scraper slides obliquely from one side to the other, concrete materials are often accumulated under the scraper, resulting in an uneven surface of the processed concrete prefabricated panel. The angle of the trowel plate in this technical solution is adjustable. When the trowel plate slides to the end of the mold 26, the trowel plate is rotated so that the trowel plate contacts the concrete surface without dead angles. When it slides in the opposite direction, the concrete material accumulated on the previous side can be smoothed by sliding in the opposite direction, making the surface of the concrete smoother.

[0044] The trowel plate also rotates with a rotating roller 16, coaxially mounted with multiple rotating discs 24. When the trowel plate rotates parallel to the concrete surface, the rotating discs 24 come into contact with the concrete. This contact allows for pre-leveling of the concrete. Some concrete materials, due to their poor fluidity, often cannot be evenly laid flat in the mold 26, resulting in gaps at the corners of the mold 26 and affecting the strength and quality of the product. Conventional vibration paving methods can result in uneven distribution of coarse and fine aggregate within the precast part. Therefore, the rotating discs 24 enable pre-leveling prior to troweling, ensuring uniform distribution of concrete within the mold 26 and ensuring subsequent troweling quality. This arrangement allows for troweling of the surface of the mold 26, which has already been filled with concrete, to be automated, achieving improved troweling quality.

[0045] Example 2

[0046] Example 2 Figure 6 As shown, the difference from Example 1 lies in that a shock-absorbing portion is provided on one side of the trowel plate. The shock-absorbing portion comprises multiple telescopic shock absorbers, each hinged at its ends to the trowel plate and the bottom of the telescopic rod 5. Each telescopic shock absorber comprises a telescopic damping rod 17 and a second spring 18 sleeved on the outer side of the telescopic damping rod 17. This arrangement allows the trowel plate to absorb and cushion the vibration and impact generated during the troweling process, helping to reduce instability caused by fluctuations in contact between the trowel plate and the concrete surface, thereby improving the smoothness of the troweled surface. The cushioning effect of the shock absorbers allows the trowel plate to operate more smoothly, reducing surface defects and unevenness, and improving the surface quality of the precast concrete part. In this embodiment, pressure sensors are provided on both sides of the trowel plate in the width direction. The control system is also included. The control system is electrically connected to the first motor 8, the second motor 15, and the pressure sensors, so that when one side of the trowel plate contacts the mold 26, it can promptly sense and adjust the trowel plate's angle.

[0047] Example 3

[0048] Example 2 Figure 7 and Figure 8 As shown, the difference from Example 1 is that a key is provided on the inner surface of the collar 10, and the rotating roller 16 is connected to the collar 10 on both sides by key. Through the above arrangement, when the rotating roller 16 rotates, the collar 10 and the pressure roller 12 can be driven to rotate synchronously. The minimum diameter of the pressure roller 12 in this embodiment is larger than the diameter of the rotating disk 24. Figure 6 and Figure 7As shown, when the trowel plate is rotated at a certain angle, the curved plate 2 can be in full contact with the side of the mold 26, avoiding dead corners in troweling and enabling comprehensive troweling of the concrete surface; when the precast concrete part is semi-solidified, when the trowel plate is rotated at a larger angle, the edges of the front and rear sides of the precast concrete part can be chamfered, and at the same time, the rotation of the rotating roller 16 in the present technical solution can cut the other two sides of the precast concrete part to form chamfers. Through the above arrangement, the surface of the precast concrete part can be chamfered. When assembling some precast concrete parts, arranging the chamfer on the bottom surface of the precast concrete part can allow excess connecting cement to flow to the chamfer, making the surface of the laid precast part smoother and strengthening the connection strength between the precast part and the wall.
