Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated steps, and more particularly to a device and method for producing prefabricated concrete steps. Background Art

[0002] Precast steps are modular components made of concrete, stone, or other materials, produced in a factory using molds. Once prefabricated, they are transported to the construction site for installation. Compared to traditional on-site casting, precast production offers advantages such as high precision, speed, and consistent quality. The production process typically includes mold design, concrete pouring, surface treatment, and maintenance, meeting the diverse design needs of the construction industry.

[0003] The production of precast steps relies on molds to ensure precise dimensions, consistent shapes, and compliance with design and quality requirements, while also improving production efficiency and reducing labor costs. During the previous precast process, some concrete will inevitably remain on the mold surface. Therefore, before the next step is poured, it is generally necessary to manually remove the concrete from the mold surface using a spatula. However, the time interval between the two step pouring processes can easily cause the residual concrete to dry out, making it even more time-consuming and labor-intensive for workers to remove. Therefore, it is necessary to propose a device and method for producing precast concrete steps to address this issue. Summary of the Invention

[0014] Compared with the prior art, the advantages of the present invention are: 1. For each step, a shell mechanism is installed on the surface of the step mold. Driven by a motor, the mobile mechanism slides in cabinets 1 and 2, thereby driving the scraping mechanism and dust removal mechanism to scrape and wipe the surface of the step mold respectively, thereby removing the residual concrete blocks and dust adhering to the surface of the step mold. Compared with manually using a spatula to remove concrete blocks, the above method is significantly more time-saving and labor-saving. In addition, the one-time scraping range is large, the cleaning speed is fast, the efficiency is higher, and the cleaning effect is better, which indirectly improves the production efficiency of prefabricated steps. At the same time, the recycling mechanism can directly collect concrete and other impurities scraped off by the scraping mechanism, preventing concrete blocks from splashing, improving safety, facilitating concrete recycling and processing, and avoiding pollution of the working environment.

[0015] 2. The motor drives the moving gear to rotate, thereby driving the rotating rod to rotate, and then the top head intermittently pushes the side rod and the vertical rod to slide, which can not only drive the grinding plate to reciprocate, rub the surface of the step mold, and grind off some small-particle concrete blocks with strong adhesion and hardness that are difficult to remove with a scraper, further improving the efficiency and effect of the scraping mechanism in removing concrete blocks; it also drives the piston to move, pumping the water in the inner cavity into the sprinkler pipe, and spraying it onto the surface of the step mold through the nozzle, thereby improving the efficiency and effect of the scraping plate in removing dust.

[0016] 3. When the box body reaches the top of cabinet No. 1 and cabinet No. 2, the pressure rod and the pressure block are inserted into the box body to move the wiping plate toward the inside of the box body. During the movement of the wiping plate, it can not only cooperate with the tooth row to turn itself 180 degrees, with the clean side facing outward, so as to facilitate better dust removal effect during the next cleaning; but also the spring can store power during the sliding process of the wiping plate. When the wiping plate is reset, the spring drives the inner ring to rotate, so that the column drives the scraper to rise, and the scraper scrapes the dirty side of the wiping plate. Several nozzles on the top surface of the scraper spray water on the dirty side of the wiping plate at the same time. The water spray cooperates with the scraper to remove the dust adsorbed by the wiping plate, maintain the cleanliness of the wiping plate, and make the wiping plate always have a good dust removal effect.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0020] For example 1, please refer to Figures 1 to 13 As shown, the present invention discloses a concrete prefabricated step production device, comprising: the shell mechanism 2 includes a first cabinet 21 and a second cabinet 22, the second cabinet 22 is staggered and arranged on the side of the first cabinet 21; A moving mechanism 3 is installed in cabinet No. 1 21 and cabinet No. 2 22. The moving mechanism 3 includes a box body 31 installed inside cabinet No. 1 21 and cabinet No. 2 22 respectively. A material guide bin 32 and a sliding bin 33 are provided in the box body 31. One end of the material guide bin 32 and the sliding bin 33 passes through the side of the box body 31. A scraping mechanism 4 is installed in the material guide bin 32, and the scraping mechanism 4 includes a scraper 41 installed in the material guide bin 32; A dust removal mechanism 5 is installed inside the sliding bin 33 . The dust removal mechanism 5 includes a wiper plate 51 installed inside the sliding bin 33 .

[0021] The outer shell mechanism 2 covers one step at a time, and a first cabinet 21 and a second cabinet 22 are set to cover the surface and side of each step of the step mold 1 respectively. The first cabinet 21 and the second cabinet 22 are staggered in height. When performing the scraping operation, the moving mechanism 3 inside the first cabinet 21 moves first, and the moving mechanism 3 inside the second cabinet 22 moves later. This ensures that the scraping mechanism 4 scrapes away the concrete blocks on the surface of the step mold 1 with the largest cleaning range, thereby reducing cleaning blind spots and improving the scraping effect.

[0022] The box body 31 inside cabinet No. 1 21 or cabinet No. 2 22 is moved by electric drive, driving the scraping mechanism 4 to scrape the surface of the step mold 1. The scraping mechanism 4 can cover the surface and side of one step at a time. Compared with the traditional method of manually scraping residual concrete blocks with a scraper, this solution saves time and effort, has a large scraping range at one time, and has a high scraping speed, higher efficiency, and better results, thereby shortening the cleaning time of the step mold 1 and indirectly improving the production efficiency of the prefabricated steps. In addition, the recycling mechanism 7 can directly collect impurities such as concrete scraped by the scraping mechanism 4, preventing concrete blocks from collapsing and splashing, improving safety, facilitating the recycling and processing of concrete, and avoiding pollution of the working environment.

[0023] Example 2: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 13 The shell mechanism 2 also includes a rack groove 23 provided on the side of cabinet No. 1 21 and cabinet No. 2 22, a positioning plate 24 is installed on the back of cabinet No. 1 21 and cabinet No. 2 22, and two pressure rods 25 are symmetrically installed on the inner top surface of cabinet No. 1 21 and cabinet No. 2 22, and a pressure block 26 is fixed to the bottom side of the pressure rod 25.

[0024] The moving mechanism 3 also includes a slide groove 34 provided in the box body 31 on both sides of the sliding warehouse 33. The box body 31 on both sides of the sliding warehouse 33 is also rotatably connected with a rotating rod 35. A cylindrical circumferential array is provided at one end of the rotating rod 35. A moving gear 37 is installed at the other end of the rotating rod 35. Brackets 38 are installed on both sides of the box body 31. The moving gear 37 is rotatably connected in the bracket 38. The bracket 38 is slidably connected in the corresponding rack groove 23, and the moving gear 37 is meshed with the rack groove 23. A motor 39 is installed on the outside of the bracket 38. The output end of the motor 39 is installed on the side of the moving gear 37. A plurality of stop teeth 391 are provided at one end of the slide groove 34 close to the moving gear 37.

[0025] The scraping mechanism 4 also includes side grooves 42 provided on both sides of the scraper 41, and a grinding plate 43 is slidably connected to the scraper 41. Side rods 44 are symmetrically installed on both sides of the grinding plate 43. The side rods 44 pass through the side grooves 42, and the bottom ends of the side rods 44 abut against the top head 36. A first spring 45 is sleeved on the side rod 44, and the side rod 44 is elastically connected to the inside of the box body 31 through the first spring 45.

[0026] A recovery mechanism 7 is provided inside the box body 31, and the recovery mechanism 7 includes a recovery box 71 slidably connected to the inside of the box body 31, a recovery groove 72 is provided in the recovery box 71, and the recovery groove 72 is communicated with the material guide bin 32, a water tank 73 is provided in the recovery box 71, and an inner cavity 74 is provided in the recovery box 71 on both sides of the water tank 73, and the inner cavity 74 is respectively communicated with the water tank 73 and the water pipe 58, a sixth spring 75 and a piston 76 are installed in the inner cavity 74, and the piston 76 is elastically connected to the inner cavity 74 through the sixth spring 75. A vertical rod 77 and a seventh spring 78 are also symmetrically installed in the box body 31, and the vertical rod 77 is elastically connected to the inside of the box body 31 through the seventh spring 78, and the bottom end of the vertical rod 77 abuts the piston 76, and the top end of the vertical rod 77 abuts the top head 36.

[0027] During use, the operator first holds the shell mechanism 2 against the surface of the step mold 1, so that the two positioning plates 24 on the back of cabinet No. 1 21 respectively contact the two sides of the step mold 1, and the back of cabinet No. 1 21 just contacts the front of the step of the step mold 1 (the front refers to the treading surface), and cabinet No. 2 22 contacts the side of the step of the step mold 1. After installing the shell mechanism 2, the operator starts the motor 39, and the motor 39 drives the moving gear 37 to rotate. Through the engagement of the moving gear 37 with the rack groove 23, the box body 31 can slide in cabinet No. 1 21 or cabinet No. 2 22, and the brackets 38 on both sides of the box body 31 also slide in the rack groove 23. First, it can keep the box body 31 sliding stably and reduce shaking. Second, the connection with the motor 39 plays a role in supporting the motor 39.

[0028] Initially, the box body 31 is located at the bottom of the No. 1 cabinet 21 and the No. 2 cabinet 22 (according to the attached Figure 1 The box body 31 in cabinet No. 1 21 is higher than the box body 31 in cabinet No. 2 22), and during the upward movement of the box body 31 driven by the moving gear 37, the scraper 41 installed in the guide bin 32 near the step mold 1 contacts the surface of each step of the step mold 1 (during the sliding process of the box body 31 in cabinet No. 2 22, the internal scraper 41 will contact the side of each step of the step mold 1. The box body 31 in cabinet No. 1 21 and its internal structure are the same as the box body 31 in cabinet No. 2 22 and its internal structure, and the working principle and state are the same. Therefore, in this embodiment, the relevant structure in cabinet No. 1 21 is mainly described), and the residual concrete blocks on the surface of the step mold 1 are shoveled off wherever they pass, and enter the recovery trough 72 along the guide bin 32 and are collected by the recovery trough 72.

[0029] When the motor 39 drives the moving gear 37 to rotate, the moving gear 37 drives the head 36 to rotate inside the box body 31 through the rotating rod 35, thereby intermittently contacting the side rod 44, causing the side rod 44 to slide upward, compressing the first spring 45 and driving the grinding plate 43 to slide upward in the scraper 41. When the head 36 does not contact the side rod 44, the first spring 45 pushes the side rod 44 to descend, and the side rod 44 drives the grinding plate 43 to slide downward. The reciprocating motion of the grinding plate 43 rubs the surface of the step mold 1, and the surface of the grinding plate 43 is relatively rough, which can grind off some small-particle concrete blocks with strong adhesion and hardness that are difficult to be removed by the scraper 41, thereby further improving the efficiency and effect of the scraping mechanism 4 in removing concrete blocks.

[0030] Example 3: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 13 The dust removal mechanism 5 also includes support plates 52 installed on both sides of the wiping plate 51. A triangular plate 53 is fixed on the outside of the support plate 52, and the triangular plate 53 is slidably connected to the corresponding slide groove 34. A second spring 54 is installed in the slide groove 34. The triangular plate 53 is elastically connected to the slide groove 34 through the second spring 54. Two flip gears 55 are symmetrically installed on both sides of the wiping plate 51, and the flip gear 55 passes through the corresponding support plate 52 and the triangular plate 53. A pipe rack 56 is fixed on the top of each support plate 52. The two pipe racks 56 are connected to the corresponding support plate 52. 6 is installed with a sprinkler pipe 57, and both ends of the sprinkler pipe 57 are connected to a water pipe 58. A vertical rod 59 is fixed to the bottom end of the triangular plate 53, and a sleeve 591 and a third spring 592 are provided at the bottom end of the vertical rod 59. The sleeve 591 is elastically connected to the vertical rod 59 through the third spring 592. A paddle 593 and a torsion spring 594 are provided at the bottom of the sleeve 591. The paddle 593 is elastically connected to the sleeve 591 through the torsion spring 594. A baffle 595 is fixed to the bottom of the sleeve 591, and the paddle 593 contacts the baffle 595.

[0031] A flip mechanism 6 is provided inside the box body 31, and the flip mechanism 6 includes a push block 61 and a fourth spring 62 installed inside the box body 31. The push block 61 is elastically connected to the inside of the box body 31 through the fourth spring 62. A tooth row 63 and a fifth spring 64 are installed in the box body 31. The tooth row 63 is elastically connected to the inside of the box body 31 through the fifth spring 64. A wedge block 65 is fixed on the top surface of the tooth row 63, and the push block 61 contacts the wedge block 65.

[0032] The recycling box 71 is provided with a cleaning mechanism 8, which includes a column 81 and an eighth spring 894 installed inside the recycling box 71. The bottom of the column 81 is elastically connected to the recycling box 71 through the eighth spring 894. The surface of the column 81 is provided with a guide groove 82. An inner ring 83 is installed in the recycling box 71. The inner ring 83 is sleeved on the top of the column 81. A protrusion 84 is fixed on the inner wall of the inner ring 83. The protrusion 84 is slidably connected to the guide groove 82. The bottom of the inner ring 83 is provided with a guide groove 82. It is equipped with a pentagonal plate 85, a spring 86 is installed on the outside of the inner ring 83, a gear ring 87 is installed on the outer end of the spring 86, a rack 88 is installed in the recovery box 71, and the rack 88 is meshed with the gear ring 87, another eighth spring 894 is installed at one end of the rack 88, an anti-rotation plate 89 is fixed to the bottom of the rack 88, a side plate 891 is fixed to the side of the rack 88, a scraper 892 is installed on the top surface of the column 81, and a number of nozzles 893 are set on the top surface of the scraper 892.

[0033] Although the scraper 41 can remove the concrete blocks remaining on the surface of the step mold 1, the dust generated during the scraping process may still adhere to the surface of the step mold 1, thereby affecting the subsequent application of the release agent. Therefore, a dust removal mechanism 5 is installed in the sliding chamber 33 below the scraper 41. During the upward sliding process of the box body 31, the wiping plate 51 wipes the surface of the step mold 1. The surface of the wiping plate 51 is covered with flannel. By wiping, the floating dust on the surface of the step mold 1 can be wiped off, further improving the cleaning effect. During the process of the wiping plate 51 wiping the step mold 1, a number of stop teeth 391 provided on one end of the chute 34 close to the step mold 1 engage with the flip gear 55, preventing the flip gear 55 from rotating, thereby locking the wiping plate 51 and preventing the wiping plate 51 from rotating.

[0034] The rotating rod 35 drives the top head 36 to rotate, and at the same time, it also contacts the top of the vertical rod 77, causing the vertical rod 77 to slide downward, thereby compressing the seventh spring 78 and squeezing the piston 76 (the outer wall of the piston 76 is an inclined surface), causing the piston 76 to slide into the inner cavity 74, compressing the sixth spring 75 while pushing the water in the inner cavity 74 into the water pipe 58 (a tubular cavity is provided in the recovery box 71, one end of the tubular cavity is connected to the top of the inner cavity 74, and the other end is open to the top surface of the recovery box 71, and the water pipe 58 is opened. 8 is movably connected to the opening of the tubular cavity. Because the recovery box 71 can be removed from the box body 31, when the recovery box 71 is removed, the water pipe 58 is disconnected from the tubular cavity). The inner cavity 74 is connected not only to the water pipe 58 but also to the water tank 73 through the tubular cavity. A one-way valve 79 is installed in the tubular cavity. When the piston 76 slides into the inner cavity 74, the one-way valve 79 in the tubular cavity connected to the water tank 73 is closed, and the one-way valve 79 in the tubular cavity connected to the water pipe 58 is opened. The water entering the water pipe 58 then enters the sprinkler pipe 57 on the pipe rack 56. The sprinkler pipe 57 is evenly spaced and has a number of nozzles 893. Water is sprayed from the nozzles 893 onto the surface of the step mold 1. The wiping plate 51 then wipes the surface of the step mold 1. After the water is sprayed, dust on the surface of the step mold 1 is more easily adsorbed by the wiping plate 51, thereby achieving a better dust removal effect.

[0035] The nozzle 893 on the sprinkler pipe 57 sprays water onto the surface of the step mold 1, allowing the wiper 51 to better wipe off the dust. However, after long-term use, the cleanliness and dust removal effect of the wiper 51 will be reduced. Therefore, each time the box body 31 slides from the bottom of cabinet No. 1 21 or cabinet No. 2 22 to the top, the pressure rod 25 and the pressure block 26 set on the top surface of cabinet No. 1 21 and cabinet No. 2 22 will be inserted into the box body 31, and the rotating rod 35 will resist and squeeze the corresponding triangular plate 53. The triangular plate 53 slides in the slide groove 34, compressing the second spring 54 while driving the support plate 52 to slide in the sliding warehouse 33. The support plate 52 drives the flip gear 55 to slide in the sliding warehouse 33. The flip gear 55 is separated from the stop tooth 391 and drives the wiper 51 to slide deep into the sliding warehouse 33. At the same time, the pressure block 26 contacts and squeezes the push block 61 inside the box body 31. The push block 61 compresses the fourth spring 62 while squeezing the wedge block 65, causing the tooth row 63 to slide downward. The tooth row 63 compresses the fifth spring 64 while sliding into the slide groove 34. The flip gear 55 will be meshed with the tooth row 63 during the sliding process in the slide groove 34, thereby driving the flip gear 55 to rotate through the tooth row 63. The flip gear 55 rotates relative to the support plate 52 and drives the wiping plate 51 to rotate. Finally, the wiping plate 51 rotates 180 degrees (rotates around the axis of the flip gear 55 as the axis), and the side that has wiped the dust rotates to face away from the step mold 1.

[0036] Remove the shell mechanism 2 from the step mold 1, and control the box body 31 to reset. During this process, the pressure rod 25 and the pressure block 26 gradually leave the box body 31. After the pressure rod 25 and the pressure block 26 leave the box body 31, under the elastic force of the second spring 54, the fourth spring 62 and the fifth spring 64, the triangular plate 53, the push block 61 and the tooth row 63 are reset, and the wiper plate 51 returns to the outer end of the sliding bin 33, and the clean side of the wiper plate 51 faces outward. The next time dust is removed, the wiper plate 51 can use the clean side for dust removal, thereby ensuring the dust removal effect.

[0037] The pressure rod 25 squeezes the triangular plate 53. As the triangular plate 53 slides within the chute 34, the triangular plate 53 drives the sleeve 591 to slide within the recovery box 71 via the vertical rod 59. When the triangular plate 53 slides to its maximum distance, the sleeve 591 passes over the side plate 891 on the side of the rack 88. During this process, the sleeve 591 drives the shift plate 593 to contact the side plate 891. Because the movement direction of the sleeve 591 does not cause the shift plate 593 to contact the baffle 595, when the shift plate 593 contacts the side plate 891, the shift plate 593 rotates, compressing the torsion spring 594, thereby allowing the sleeve 591 to smoothly pass over the side plate 891. During the resetting process of the triangular plate 53, the vertical rod 59 drives the sleeve 591 to return, and the dial plate 593 at the bottom of the sleeve 591 again contacts the side plate 891. In this direction, the dial plate 593 contacts the baffle 595 due to the obstruction of the side plate 891. The baffle 595 prevents the dial plate 593 from rotating, so the dial plate 593 cannot rotate, and drives the rack 88 to slide through the side plate 891. The rack 88 drives the anti-rotation plate 89 to slide synchronously and compresses the eighth spring 894 installed at the end of the rack 88 (the spring on the rack 88 and the spring installed at the bottom of the column 81 are the same type of spring, the eighth spring 894). First, the end of the rack 88 close to the step mold 1 is shorter than the anti-rotation plate 89, and the end of the rack 88 away from the step mold 1 is longer than the anti-rotation plate 89. Therefore, when the rack 88 and the anti-rotation plate 89 begin to slide, the anti-rotation plate 89 first contacts the pentagonal plate 85, preventing the pentagonal plate 85 from rotating. Then the rack 88 drives the gear ring 87 to rotate, and the rotation of the gear ring 87 causes the mainspring 86 to store power. When the dust removal mechanism 5 is fully reset, the rack 88 slides to the maximum distance. At this time, since the end of the rack 88 away from the step mold 1 is longer than the anti-rotation plate 89, the rack 88 is still engaged with the gear ring 87, which is equivalent to locking the gear ring 87, and the anti-rotation plate 89 is separated from the pentagonal plate 85. Under the elastic force of the spring 86, the pentagonal plate 85 rotates, and the pentagonal plate 85 drives the inner ring 83 to rotate. The convex column 84 on the inner side of the inner ring 83 cooperates with the guide groove 82 to make the column 81 slide upward. The column 81 compresses the eighth spring 894 while driving the scraper 892 to slide upward. The scraper 892 drives the nozzle 893 to rise from the recovery box 71. The scraper 892 scrapes the dirty side of the wiper plate 51. The bottom of the column 81 is a rectangular structure, which cooperates with the inside of the recovery box 71 to prevent the column 81 from rotating, thereby allowing the column 81 to rise and fall better. At the same time, the water pump inside the water tank 73 starts to pump water into the scraper 892 (a water pump is installed in the water tank 73, not shown in the figure, and a pipe is provided inside the scraper 892, which is respectively connected to several nozzles 893 and the output end of the water pump). Finally, water is sprayed out from the several nozzles 893 and sprayed onto the surface of the wiping plate 51. The water spraying cooperates with the scraping of the scraper 892 to squeeze out the water absorbed in the wiping plate 51. The dust adsorbed in the wiping plate 51 can be scraped off together with the water, and finally the sewage flows into the recovery tank 72.

[0038] The guide groove 82 consists of a spiral groove surrounding the column 81 and a vertical groove connected to the end of the spiral groove. When the column 81 starts to rise, the lowest point of the spiral groove approaches the boss 84. When the boss 84 is at the lowest point of the spiral groove, it is also the lowest point where it enters the vertical groove. Then, under the elastic force of the eighth spring 894, the boss 84 slides in the vertical groove, and the column 81 falls rapidly, driving the scraper 892 and the nozzle 893 back to the recovery box 71.

[0039] This embodiment also discloses a method for using a prefabricated concrete step production device, comprising the following steps: S1: First, apply a release agent to the surface of the step mold 1, then inject concrete into the space formed by the step mold 1. After the concrete dries and agglomerates, separate the step mold 1 and remove the formed concrete step; S2: The back of cabinet No. 1 21 is against the pedestrian surface at one end of the step mold 1, and cabinet No. 2 22 is against the side of the step, and the positioning plates 24 on the back of cabinet No. 1 21 and cabinet No. 2 22 are clamped on both sides of the step mold 1; S3: Start the motor 39 to drive the moving gear 37 to rotate in the rack groove 23, thereby driving the box body 31 inside the No. 1 cabinet 21 and the No. 2 cabinet 22 to rise; S4: During the movement of the box body 31, the scraper 41 protruding from one side of the box body 31 against the surface of the step mold 1 scrapes the surface of the step mold 1 to remove large chunks of concrete, and the scraper 51 below the scraper 41 wipes off the dust on the surface of the step mold 1; S5: The movable gear 37 drives the rotating rod 35 to rotate, causing the grinding plate 43 to reciprocate and grind the hard-to-remove concrete blocks on the surface of the step mold 1; when the box body 31 reaches the top of the No. 1 cabinet 21 and the No. 2 cabinet 22, the pressing rod 25 drives the wiping plate 51 to flip and clean, so that the surface of the wiping plate 51 is clean when cleaning next time; S6: After the cleaning is completed, the first cabinet 21 and the second cabinet 22 are removed and the production of the next prefabricated step is continued.
