Description

Technical Field

[0001] The present invention relates to the technical field of building prefabrication production, and particularly to a prefabricated component production line for buildings. Background Art

[0002] Prefabricated components for buildings include beams, slabs, columns, and building decoration fittings, etc. Prefabricated components are building components prefabricated in a factory with concrete as the basic material for on-site assembly. They are the material basis for building industrialization. Concrete prefabricated components are widely used in the fields of construction, transportation, water conservancy, etc., and play an important role in the national economy. Such as precast reinforced concrete column foundations, precast steel structure steel column foundations, reinforced concrete foundations for street lamp billboard columns, and precast floor slabs.

[0003] Among them, the production process of prefabricated components is divided into processes such as building construction drawing design, component disassembly design, mold design drawings, mold manufacturing, steel bar processing and binding, embedding of water and electricity prefabricated parts and doors and windows, pouring concrete, curing, etc. Among them, in the mold manufacturing of concrete prefabricated components, it is further divided into processes such as mold table mold cleaning, applying mold release agent to the table mold, and component support.

[0004] In the prior art, the cleaning process of the mold table mold is divided into fixed table mold and moving table mold cleaning. Among them, in the moving table mold cleaning, mainly the table mold is driven by a cylinder or an oil cylinder to pass through the cleaning table to clean the residual concrete residues on the surface of the table mold. The cleaning table in the prior art has two problems: First, the cleaning table in the prior art mainly uses the front scraper to clean the residual concrete on the surface of the table mold, and mainly relies on the gap between the table mold and the scraper to scrape off the residues. In this way, the concrete within the gap is not easily cleaned, and at the same time, the heights of different types of table molds are different, and the height between the cleaning mechanism at the top of the prior art and the table mold is also not adjustable. In this way, a cleaning table cannot adapt to the cleaning table surfaces of various types of table molds with different heights; Second, in the prior art, when cleaning the concrete on the surface of the table mold, the residual concrete is directly scraped into the cleaning tank, and the residual concrete is not treated at all, which is more troublesome in subsequent recycling. At the same time, a large amount of dust will be generated when scraping the concrete, which greatly affects the working environment and also has a certain impact on the health of workers. Summary of the Invention

[0005] The purpose of the present invention is to provide a prefabricated component production line for buildings, which solves the problems of unclean cleaning of the table mold and difficult recycling of the residual concrete without treatment in the prior art.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A prefabricated component production line for construction, comprising a workbench. A conveying component is arranged at the bottom of the workbench. The conveying component is connected with a dust suction component through a connecting belt. A cleaning mechanism is arranged above the conveying component. Lifting components are arranged on both sides of the cleaning mechanism. A driving motor is arranged at the top of the workbench. The output end of the driving motor is provided with a transmission shaft. The transmission shaft is movably connected with the cleaning mechanism through a connecting piece.

[0008] Preferably, the cleaning mechanism comprises a cleaning table and a cleaning component. A cleaning groove is formed inside the cleaning table. Three meshing gears are arranged inside the cleaning groove. The lower part of the gear is connected with the cleaning component through a connecting rod. Scrapers are detachably connected to the front and rear sides of the cleaning table.

[0009] Preferably, the cleaning component comprises a rotating disc and a cleaning brush. A number of annularly distributed limiting buckles are arranged on the rotating disc. An activity groove adapted to the limiting buckle is formed on the surface of the cleaning brush.

[0010] Preferably, the lifting component comprises a rotating frame, a moving rod and a disc. One end of the moving rod is fixedly connected to both sides of the cleaning table. The other end of the moving rod is slidably connected to the inner wall of the workbench. A lifting belt is sleeved on the moving rod. The lifting belt is fixedly connected with the rotating frame. Rotating rods are arranged on both sides of the rotating frame. One side of the rotating rod is fixedly connected with the disc.

[0011] Preferably, a receiving groove is arranged on one side of the workbench. One end of the rotating rod penetrates through the receiving groove. A toothed ring is sleeved on the side of the rotating rod close to the disc. A driven wheel is arranged through the rotating rod. The driven wheel is fixedly connected with the receiving groove.

[0012] Preferably, a matching groove is formed on the other side of the workbench. The other end of the rotating rod is located in the matching groove. A convex block is arranged at the other end of the rotating rod. Limiting grooves matched with the convex block are arranged above and below the matching groove.

[0013] Preferably, sliding grooves are formed on the opposite sides of the workbench. The moving rod is slidably connected with the sliding grooves.

[0014] Preferably, the connecting piece comprises a connecting block. A through groove is formed inside the cleaning table. The connecting block is located in the through groove. The connecting block is rotatably connected with the cleaning table. A cylindrical groove is formed on the surface of the connecting block. The transmission shaft is inserted into the cylindrical groove. Moving blocks are arranged on both sides of the transmission shaft. A strip-shaped groove is formed inside the connecting block. The moving block is slidably connected with the strip-shaped groove.

[0015] Preferably, an annular groove is formed inside the cleaning table. A transverse block is arranged on the surface of the connecting block. The transverse block is slidably connected with the annular groove.

[0016] Preferably, the conveying component comprises a rotating cylinder. The rotating cylinder is rotatably connected with the inner wall of the workbench through a rotating shaft. A plurality of rotating cylinders are arranged at the bottom of the workbench.

The fan is rotationally connected to the dust suction groove through a central shaft, and the central shaft of the fan rotates synchronously with the connecting belt.

[0018] The present invention has at least the following beneficial effects:

[0019] In the present invention, scrapers are provided on both the front and rear sides of the cleaning table. When the table mold moves, the scraper on the front side of the cleaning table first performs a preliminary scraping on it, then the secondary brushing is performed by the cleaning assembly, and then the three - time scraping is performed by the scraper on the rear side. The scraper on the rear side is lower in position than the scraper on the front side. The cleaning of the tabletop of the table mold is carried out through multiple cooperations. By setting up a cleaning mechanism to clean the table mold, the cleaning mechanism divides the cleaning of the table mold into three steps. Therefore, compared with the prior art in which the residual concrete on the surface of the table mold is mainly cleaned by the front scraper, and the residue is mainly scraped off by the gap between the table mold and the scraper, the multi - layer cleaning in this solution has a better cleaning effect and is cleaner; at the same time, when dealing with table molds of different models and different heights, pull the rotating rod outwards to disengage the toothed ring on the rotating rod from the driven wheel, and then rotate the rotating rod to drive the lifting belt to move upwards, thereby driving the cleaning mechanism to move upwards, so that it can adapt to cleaning the tabletop of table molds of different heights; through the self - rotation of the table mold during the cleaning process, the rotating cylinder is driven to rotate. Through the interaction between the rotating cylinders, large concrete residues are crushed. The rotating cylinder can perform primary crushing treatment, which is convenient for subsequent recycling; when the rotating cylinder rotates, the fan is driven to rotate through the connecting belt, thereby sucking away the dust generated during the concrete scraping process, reducing the impact on the working environment and at the same time reducing the impact on the health of workers.

Detailed implementation mode

[0031] In order to make the purpose, technical solutions and advantages of the present invention clearer, the following further elaborates on the present invention in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0032] Example 1, please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 and Figure 7, A prefabricated component production line for construction, including a workbench 1. A conveying component 2 is arranged at the bottom of the workbench 1. The conveying component 2 is connected to a dust suction component 4 through a connecting belt 3. A cleaning mechanism 5 is arranged above the conveying component 2. Lifting components 6 are arranged on both sides of the cleaning mechanism 5. A driving motor 7 is arranged on the top of the workbench 1. The output end of the driving motor 7 is provided with a transmission shaft 8. The transmission shaft 8 is movably connected to the cleaning mechanism 5 through a connecting piece 9. Specifically, during use, the table mold moves forward in the conveying component 2. When the table mold moves in the conveying component 2, the conveying component 2 drives the dust suction component 4 to suck dust through the connecting belt 3. At the same time, the table mold uses the cleaning mechanism 5 at the bottom to clean the residual concrete on the surface. Compared with the prior art, the linkage method can not only clean the surface of the table mold, but also perform primary treatment on the residual concrete for convenient recycling.

[0033] Further, the cleaning mechanism 5 includes a cleaning table 501 and a cleaning component 502. A cleaning groove 503 is opened inside the cleaning table 501. Three meshing gears 504 are arranged inside the cleaning groove 503. The lower part of the gear 504 is connected to the cleaning component 502 through a connecting rod 505. Scrapers 506 are detachably connected to the front and rear sides of the cleaning table 501. Specifically, through the meshing between the three gears 504, when the middle gear 504 rotates, it drives the two side gears 504 to rotate. At the same time, according to the principle of coaxial rotation, it drives the cleaning component 502 at the bottom to rotate.

[0034] Furthermore, the cleaning component 502 includes a rotating disk 5021 and a cleaning brush 5022. A number of annularly distributed limiting buckles 5023 are arranged on the rotating disk 5021. An activity groove 5024 adapted to the limiting buckles 5023 is opened on the surface of the cleaning brush 5022. Specifically, during use, the rotation of the gear 504 drives the connecting rod 505 to rotate. The connecting rod 505 drives the rotating disk 5021 in the cleaning component 502 to rotate. The rotation of the rotating disk 5021 drives the cleaning brush 5022 to rotate. The cleaning brush 5022 performs an arc movement around the limiting buckles 5023, thereby brushing the surface of the table mold. The cooperation between the activity groove 5024 and the limiting buckles 5023 can make the movement intensity and movement track of the cleaning brush 5022 larger, and the overall cleaning is cleaner.

[0035] Furthermore, the lifting assembly 6 includes a rotating frame 601, a moving rod 602 and a disc 603. One end of the moving rod 602 is fixedly connected to both sides of the cleaning table 501, and the other end of the moving rod 602 is slidably connected to the inner wall of the workbench 1. A lifting belt 604 is sleeved on the moving rod 602, and the lifting belt 604 is fixedly connected to the rotating frame 601. Rotating rods 605 are provided on both sides of the rotating frame 601, and the rotating rod 605 on one side is fixedly connected to the disc 603. Specifically, the turntable is rotated, and the turntable drives the rotating frame 601 to rotate, thereby driving the lifting belt 604 to drive the cleaning table 501 to move up and down. The height of the table molds of different models is different, and the height of the cleaning table 501 can be adjusted to clean the table mold.

[0036] Furthermore, a receiving groove 606 is provided on one side of the workbench 1, one end of the rotating rod 605 passes through the receiving groove 606, a toothed ring 607 is sleeved on the side of the rotating rod 605 close to the disc 603, and a driven wheel 608 is penetrated by the rotating rod 605, and the driven wheel 608 is fixedly connected to the receiving groove 606. Specifically, the driven wheel 608 and the toothed ring 607 cooperate to limit the rotating rod 605, and the driven wheel 608 is sleeved on the rotating rod 605. The rotating rod 605 rotates to drive the driven wheel 608 to rotate. When the rotating rod 605 does not rotate, it pushes the rotating rod 605, and the toothed ring 607 on the rotating rod 605 engages with the driven wheel 608, so that the rotating rod 605 does not rotate.

[0037] Furthermore, a mating groove 609 is opened on the other side of the workbench 1, and the other end of the rotating rod 605 is located in the mating groove 609. A protrusion 610 is provided at the other end of the rotating rod 605. The mating groove 609 is provided with limiting grooves 611 that cooperate with the protrusion 610 above and below. Specifically, the protrusion 610 and the limiting groove 611 limit the position of the rotating rod 605 to prevent it from leaving the mating groove 609.

[0038] Furthermore, sliding grooves 612 are provided on two opposite sides of the workbench 1, and the moving rod 602 is slidably connected to the sliding grooves 612. Specifically, the sliding grooves 612 limit the movement direction of the cleaning table 501 to keep the cleaning mechanism 5 able to move vertically.

[0039] Furthermore, the connecting member 9 includes a connecting block 901, a through groove 902 is provided in the cleaning table 501, the connecting block 901 is located in the through groove 902, the connecting block 901 is rotatably connected to the cleaning table 501, a cylindrical groove 903 is provided on the surface of the connecting block 901, the transmission shaft 8 is inserted into the cylindrical groove 903, and moving blocks 904 are provided on both sides of the transmission shaft 8. A strip groove 905 is provided in the connecting block 901, and the moving block 904 is slidably connected to the strip groove 905. Specifically, the connection member 9 is arranged so that when the lifting component 6 moves up and down, the transmission shaft 8 can be always connected to the cleaning mechanism 5 through the connecting member 9, so as to ensure that the transmission shaft 8 can always drive the gear 504 to rotate, thereby driving the cleaning component 502 to move.

[0040] Furthermore, an annular groove 906 is provided in the cleaning table 501, and a cross block 907 is provided on the surface of the connecting block 901. The cross block 907 is slidably connected to the annular groove 906. Specifically, the annular groove 906 and the cross block 907 limit the position of the connecting block 901 to prevent it from detaching from the cleaning table 501 when rotating. After the setting, it can rotate without detaching, thereby ensuring the reliability of operation.

[0041] This program has the following working process:

[0042] When in use, the driving motor 7 is started, and the driving motor 7 drives the connecting member 9 to rotate through the transmission shaft 8. The connecting member 9 drives the middle gear 504 in the bottom cleaning mechanism 5 to rotate through the connecting block 901. Since the gears 504 and the gears 504 are in a meshing state, the middle gear 504 drives the gears 504 on both sides to rotate. The gears 504 drive the bottom cleaning assembly 502 to rotate through the connecting rod 505. The connecting rod 505 rotates coaxially with the rotating disk 5021. The rotating disk 5021 drives the cleaning brush 5022 to move. The cleaning brush 5022 continuously moves around the limit buckle 5023 through the movable groove 5024 on the surface, thereby cleaning the concrete on the surface of the table formwork. Scrapers 506 are provided on both the front and rear sides of the table 501. When the table mold moves, the scraper 506 on the front side of the cleaning table 501 performs preliminary scraping, and then the cleaning component 502 performs secondary brushing, and then the scraper 506 on the rear side performs tertiary scraping. The scraper 506 on the rear side is located lower than the scraper 506 on the front side, and the table mold surface is cleaned through multiple cooperations; when it comes to table molds of different models and heights, the rotating rod 605 is pulled outward to disengage the gear ring 607 on the rotating rod 605 from the driven wheel 608, and then the rotating rod 605 is rotated to drive the lifting belt 604 to move upward, thereby driving the cleaning mechanism 5 to move upward, thereby being able to adapt to table molds of different heights to clean the table 501 surface.

[0043] According to the above working process, we can know that:

[0044] In the present invention, a cleaning mechanism 5 is provided to clean the table mold. The cleaning mechanism 5 divides the cleaning of the table mold into three steps. Scrapers 506 are provided on both the front and rear sides of the cleaning table 501. When the table mold moves, the scraper 506 on the front side of the cleaning table 501 first performs a preliminary scraping on it, then the cleaning assembly 502 performs a secondary brushing on it, and then the scraper 506 on the rear side performs a third scraping. The scraper 506 on the rear side is lower in position than the scraper 506 on the front side. Through multiple cooperations, the surface of the table mold is cleaned. Therefore, compared with the prior art in which the residual concrete on the surface of the table mold is mainly cleaned by the front scraper 506 and the residue is mainly scraped off by the gap between the table mold and the scraper 506, the multi-layer cleaning in this solution has a better cleaning effect and is cleaner; at the same time, when dealing with table molds of different models and different heights, pull the rotating rod 605 outwards to disengage the toothed ring 607 on the rotating rod 605 from the driven wheel 608, and then rotate the rotating rod 605. The rotating rod 605 drives the lifting belt 604 to move upwards, thereby driving the cleaning mechanism 5 to move upwards, so that it can adapt to cleaning the surface of the cleaning table 501 of table molds of different heights.

[0045] Example two, please refer to Figure 5 、 Figure 8 and Figure 9 and, the conveying component 2 includes a rotating cylinder 201. The rotating cylinder 201 is rotationally connected to the inner wall of the workbench 1 through a rotating shaft 202. A plurality of rotating cylinders 201 are provided at the bottom of the workbench 1. Specifically, the table mold is placed on the conveying component 2, and then the table mold is driven to move by a cylinder. When the table mold moves on the conveying component 2, the table mold drives the rotating cylinder 201 to rotate, and the removed concrete falls into the collection box below through the rotating cylinder 201. When the concrete rotates through the rotating cylinder 201, the large concrete residues can be subjected to primary crushing treatment through the acting force between the rotating cylinders 201, which is convenient for later recycling.

[0046] Furthermore, the dust suction component 4 includes a fan 401. Dust suction grooves 402 are opened on both sides of the workbench 1. The fan 401 is located in the dust suction grooves 402. The fan 401 is rotationally connected to the dust suction grooves 402 through a central shaft 403. The central shaft 403 of the fan 401 rotates synchronously with the connecting belt 3. Specifically, when the rotating cylinder 201 rotates, it drives the dust suction component 4 to move through the connecting belt 3. The dust suction component 4 is composed of the fan 401. An air outlet channel (not marked in the figure) that cooperates with the fan 401 is provided on one side of the workbench 1. Through coaxial rotation, the connecting belt 3 drives the fan 401 to rotate, and the fan 401 can suck away the dust generated during the concrete scraping process.

[0047] This solution has the following working process:

[0048] In this solution, during the cleaning process, the table form rotates by itself, driving the rotating cylinder 201 to rotate. Through the interaction between the rotating cylinder 201 and the rotating cylinder 201, large concrete residues are crushed. The rotating cylinder 201 can perform primary crushing treatment, facilitating subsequent recycling treatment. When the rotating cylinder 201 rotates, the fan 401 is driven to rotate through the connecting belt 3, thereby sucking away the dust generated during the concrete scraping process, reducing the impact on the working environment and simultaneously minimizing the impact on the health of workers.
