Description

Technical Field

[0001] The invention belongs to the technical field of concrete slab production equipment, in particular to a continuous concrete slab production equipment. Background Art

[0002] Concrete slab, also known as reinforced concrete slab, is a slab made of reinforced concrete material. It is the basic structure or component in house construction and various engineering structures. It is often used as roof, floor, platform, wall retaining wall, foundation, floor, pavement, pool, etc. It has a wide range of applications. Concrete slabs are divided into square slabs, round slabs and special-shaped slabs according to their plane shape. They are divided into one-way slabs and two-way slabs according to the force action mode of the structure. The most common ones are one-way slabs, four-side supported two-way slabs and beamless slabs supported by columns. The thickness of the slab should meet the requirements of strength and stiffness.

[0003] A Chinese patent with publication number CN219171253U discloses a casting device for the production of reinforced concrete prefabricated panels of concrete structures, which belongs to the technical field of concrete structure production, and includes a fixed base, a fixed frame, a screw slide rail, a support frame, a slide rail A, a sliding frame, an electric roller A, a storage tank, a guide pipe, a concrete delivery pump and a casting platform. Fixed frames are fixedly installed at both ends of the top of the outer wall of the fixed base, and screw slide rails are fixedly installed on the opposite surfaces of the top of the outer wall of the fixed frame; after the concrete is evenly poured into the space between the baffle and the sliding baffle by the guide pipe at the bottom of the sliding frame, the staff buries the steel frame in the concrete, and then pulls the relative slide groove B to slide on the surface of the slide rail C to a specified position through the slider, so that the limit frame is at the top of the steel bar that needs to be fixed. After that, the staff pushes the limit frame to slide downward on the inner side of the slide groove B and contacts the steel bar surface of the steel frame. After the steel frame is limited, the steel frame can be prevented from deflecting.

[0004] In the above technology, the steel frame is limited to prevent it from being offset and reducing the quality of the cast concrete slab. However, the diameter of the storage tank when discharging materials is fixed. If thick concrete slabs need to be cast, it is necessary to cast twice more or reduce the operating speed of the storage tank to cast more concrete, resulting in a lower casting speed. If thin concrete slabs need to be cast, it is necessary to increase the operating speed of the storage tank and reduce the discharge. The fast speed may cause part of the concrete to not fall, resulting in the concrete may not reach the predetermined thickness.

[0043] Usually, the diameter of the storage tank is fixed when discharging. If a thick concrete slab needs to be poured, it is necessary to pour twice more or reduce the running speed of the storage tank to pour more concrete, resulting in a lower pouring speed. If a thin concrete slab needs to be poured, it is necessary to increase the running speed of the storage tank and reduce the discharge. A fast speed may cause some concrete to not fall, resulting in the concrete not reaching the predetermined thickness.

[0044] Based on the above, when the dispensing unit provided by the present invention is in use, the second motor 575 is turned on through the cooperation of the bidirectional ball screw 574, the rotating wheel 576, and the belt 577. The second motor 575 drives the connected bidirectional ball screw 574 to rotate through the output shaft, and the connected rotating wheel 576 is driven to rotate through the rotation of the bidirectional ball screw 574, and the belt 577 is driven to rotate through the rotating wheel 576. The belt 577 drives another rotating wheel 576 to rotate, and the connected bidirectional ball screw 574 is driven to rotate through the rotating wheel 576, thereby realizing the two bidirectional ball screws 574. 74 synchronous rotation; since the connection between the bidirectional ball screw 574 and the connecting plate 573 is provided with a ball nut seat, the radial movement of the connecting plate 573 is ensured by the ball nut seat, so that the bidirectional ball screw 574 drives the connecting plate 573 to move in opposite directions, and the connecting plate 573 drives the material distribution box 571 to move in opposite directions. Through computer program control, according to the thickness of the cast concrete slab and the running speed of the electric guide rail 4, the second motor 575 is controlled to drive the material distribution box 571 to a suitable position, so as to realize the function of controlling the concrete flow rate by controlling the size of the discharge port;

[0045] Working process as Figure 1 As shown, the two molds 3 are respectively recorded as the first mold and the second mold, the area on the slide rail 7 corresponding to the electric guide rail 4 is recorded as the preparation area, and the areas on the slide rail 7 located on both sides of the electric guide rail 4 are respectively recorded as the first waiting area and the second waiting area; during operation, in the preparation area as described above, concrete is poured in the first mold, and the storage tank is in the process of moving forward, and the scraping plate 6 at the rear scrapes the concrete flat, and the scraping plate 6 at the front has residual material adhered to it during the previous period of scraping. When the residual material needs to be cleaned, the electric push rod 62 is turned on, and the electric push rod 62 drives the scraping rod to move, and the scraping rod cleans the residual material on the inner side of the scraping plate 6 to realize the function of cleaning the residual material; when the concrete slab is poured in the preparation area, the first mold can be moved to the first waiting area through the slide rail 7 and the limit frame 2, and then The second mold in the second waiting area is slid to the preparation area through the slide rail 7 and the limit frame 2 to cast and level the concrete slab. After the casting is completed, the second mold is moved to the second waiting area again; during this time, the concrete in the first mold is completely solidified, and then the first mold is moved from the first waiting area to the preparation area, and then it is cured. Spraying is required during the curing process. Water is transported to the water storage box 63 through the water inlet pipe 64, and then sprayed on the concrete slab through the guide groove 66 to achieve a wide range of curing. Driven by the electric guide rail 4 and the reciprocating screw 42, the concrete slab is cured as a whole. After the curing is completed, the concrete slab can be taken out and then the preparation is continued; this reciprocating process is repeated, and the two molds 3 are used alternately to alternate the casting and curing work, thereby realizing the continuous production of the concrete slab.

[0046] In a specific implementation, since the bottom inner wall of the distribution box 571 is flush with the bottom of the mixing tank 5, when the distribution box 571 moves to both sides, the concrete is scraped off by the storage tank, and the residual material on the distribution box 571 needs to be cleaned regularly.

[0047] like Figures 1 to 3 As shown, the tops of the two electric guide rails 4 are movably connected with a telescopic frame 41; the top of the telescopic frame 41 is rotatably connected with a reciprocating screw rod 42 through a bearing; two movable plates 44 are threadedly connected to the reciprocating screw rod 42; two guide rods 43 are slidably connected to the two movable plates 44; both ends of the guide rods 43 are fixedly connected to the telescopic frame 41; the mixing tank 5 is fixedly connected between the two movable plates 44.

[0048] When the electric guide rail 4, reciprocating screw rod 42 and telescopic frame 41 provided by the present invention are in use, the electric guide rail 4 drives the material storage tank to move longitudinally in the mold 3 for casting; the reciprocating screw rod 42 drives the material storage tank to move laterally in the mold 3 for casting; the telescopic frame 41 drives the material storage tank and the scraper plate 6 to move in the vertical direction, which is suitable for casting concrete slabs of different thicknesses. Through the cooperation of the electric guide rail 4, the reciprocating screw rod 42 and the telescopic frame 41, the casting range is expanded and the applicability of the material storage tank casting is improved.

[0049] like Figure 1 and Figure 4 As shown, a driving motor 52 is fixedly connected to the top of the mixing tank 5; the output shaft of the driving motor 52 is rotatably connected to the mixing tank 5; the output shaft of the driving motor 52 is fixedly connected to a second rotating rod 53; three stirring rods 54 are fixedly connected to the second rotating rod 53; a spiral blade 55 is fixedly connected to the bottom end of the second rotating rod 53; two scraping rods 56 are fixedly connected to the top of the second rotating rod 53; the scraping rods 56 are in contact with the inner wall of the storage tank; the top of the mixing tank 5 is connected and fixedly connected to a feed hopper 51.

[0050] Concrete is poured into the storage tank through the feed hopper 51, and the concrete needs to be stirred evenly. When the stirring rod 54, the spiral blade 55 and the scraper rod 56 provided by the present invention are used, the drive motor 52 is turned on, and the second rotating rod 53 is driven to rotate by the drive motor 52, and the stirring rod 54, the spiral blade 55 and the scraper rod 56 are driven to rotate by the second rotating rod 53. The stirring rod 54 fully stirs the concrete when rotating; when the spiral blade 55 rotates, it can not only stir the concrete, but also dredge the discharge when discharging; when the scraper rod 56 rotates, it scrapes off the residual material on the inner wall of the mixing tank 5, which can not only reduce the waste of concrete, but also prevent the residual material from being mixed with the concrete of the next feed, affecting the quality of the concrete, and it is easy to solidify for a long time, which is inconvenient to clean.

[0051] like Figure 4As shown, the spiral blade 55 is arranged at the bottom end of the storage tank, and the pitch of the spiral blade 55 gradually increases from top to bottom.

[0052] When discharging concrete, the discharge port is relatively small and the concrete may be squeezed together to discharge, causing blockage. When the spiral blade 55 provided by the present invention is in use, the pitch of the spiral blade 55 gradually increases from top to bottom. During the discharging process, the concrete is transported more and more sparsely by the spiral blade 55, which facilitates orderly discharging.

[0053] like Fig. 9 As shown, the two inner side walls of the limit frame 2 that are perpendicular to the electric guide rail 4 are fixedly connected to the limit rail 21; the two outer side walls of the mold 3 are fixedly connected to the sliders 32; the sliders 32 slide in the corresponding limit rails 21; the bottom inner wall of the limit frame 2 is rotatably connected to four rollers 39 through bearings; the rollers 39 are arranged at the four corners of the mold 3 and are in contact with the bottom of the mold 3; the movement direction of the rollers 39 is perpendicular to the electric guide rail 4.

[0054] Bubbles mixed in concrete are prone to produce pores during pouring, resulting in defects in the formation of concrete slabs. By setting a shaking operation, defoaming is performed. When the limit rail 21 provided by the present invention is in use, when the mold 3 is shaken, the mold 3 drives the slider 32 to slide on the limit rail 21, and the limit roller limits the slider 32 in the horizontal direction; a roller 39 is set at the bottom of the mold 3 to prevent the mold 3 and the concrete slab from being too heavy as a whole and difficult to push.

[0055] like Figure 7 As shown, the first push plate 22 and the second push plate 36 are respectively provided on both sides of the mold 3; both ends of the first push plate 22 and the second push plate 36 are slidably connected to the limit rail 21; two first springs 23 are symmetrically fixedly connected between the first push plate 22 and the inner wall of the limit frame 2; two second springs 37 are symmetrically fixedly connected between the second push plate 36 and the inner wall of the limit frame 2.

[0056] When the first spring 23 and the second spring 37 provided by the present invention are in use, the first spring 23 and the second spring 37 have good resetting and shaking effects, and the first spring 23 and the second spring 37 facilitate the continuous shaking operation of the mold 3.

[0057] like Figure 7 As shown, two threaded bolts 24 are symmetrically fixed to the first push plate 22 ; one end of the threaded bolt 24 extends through the outside of the limiting frame 2 ; and the outside of the threaded bolt 24 is threadedly connected with a fastening nut 25 .

[0058] When the threaded bolt 24 provided by the present invention is in use, the threaded bolt 24 extends through the interior of the limit frame 2. When shaking is required, the fastening nut 25 is rotated to the end away from the first push plate 22. When the second push plate 36 is driven to move, the first push plate 22 has sufficient movement space to facilitate the shaking of the mold 3. Then, after standing for a period of time, the concrete slab is formed. When the material needs to be taken, the fastening nut 25 is rotated to the end close to the first push plate 22, so that the first push plate 22 is fixed. By driving the second push plate 36 to hit the mold 3, the mold 3 is separated from the concrete slab, which is convenient for the concrete slab to be taken out.

[0059] like Figure 8 As shown, two first fixing plates 38 are fixedly connected to the top of the base plate 1; a first rotating rod 35 is rotatably connected between the first fixing plates 38 via a rotating shaft; two elliptical blocks 34 are symmetrically fixedly connected to the outer wall of the first rotating rod 35; the elliptical blocks 34 are vertically arranged between the second push plate 36 and the fixed frame; a first motor 33 is fixedly connected to one of the second fixing plates 572; and the output shaft of the first motor 33 is fixedly connected to one end of the first rotating rod 35.

[0060] When in use, the elliptical block 34 provided by the present invention is convenient for driving the movement of the second push plate 36, turning on the first motor 33, and driving the first rotating rod 35 to rotate through the first motor 33, and the first rotating rod 35 drives the elliptical block 34 to rotate. When the long semi-axis of the elliptical block 34 is vertical, the first spring 23 and the second spring 37 are both in a balanced state. When the long semi-axis of the elliptical block 34 is horizontal, the first spring 23 is compressed, the second spring 37 is extended, and the second push plate 36 pushes the mold 3. Then the elliptical block 34 continues to rotate. Under the action of the first spring 23 and the second spring 37, the first push plate 22 and the second push plate 36 are reset, and the first push plate 22 pushes the mold 3, thereby realizing the function of shaking the mold 3.

[0061] Working principle: Usually, the diameter of the storage tank during discharge is fixed. If thick concrete slabs need to be poured, it is necessary to pour twice more or reduce the running speed of the storage tank so that more concrete is poured, resulting in a lower pouring speed. If thin concrete slabs need to be poured, it is necessary to increase the running speed of the storage tank and reduce the discharge. A fast speed may cause part of the concrete to not fall, resulting in the concrete not reaching the predetermined thickness. The second motor 575 is turned on through the cooperation of the bidirectional ball screw 574, the rotating wheel 576, and the belt 577. The second motor 575 drives the connected bidirectional ball screw 574 to rotate through the output shaft, and the connected bidirectional ball screw 574 is driven to rotate through the rotation of the bidirectional ball screw 574. The connected wheel 576 rotates, and the belt 577 rotates through the wheel 576, and the belt 577 drives another wheel 576 to rotate, and the connected bidirectional ball screw 574 is driven to rotate through the wheel 576, so as to realize the synchronous rotation of the two bidirectional ball screws 574; because the connection between the bidirectional ball screw 574 and the connecting plate 573 is provided with a ball nut seat, the radial movement of the connecting plate 573 is guaranteed by the ball nut seat, so that the bidirectional ball screw 574 drives the connecting plate 573 to move in the opposite direction, and the connecting plate 573 drives the material distribution box 571 to move in the opposite direction, and the computer program is controlled according to the thickness of the cast concrete slab and the electric guide rail 4. The running speed is controlled to control the second motor 575, drive the distributing box 571 to a suitable position, and realize the function of controlling the flow rate of concrete by controlling the size of the discharge port; the concrete is poured into the storage tank through the feed hopper 51, and the concrete needs to be mixed evenly, and the driving motor 52 is turned on, and the second rotating rod 53 is driven to rotate by the driving motor 52, and the stirring rod 54, the spiral blade 55 and the scraper rod 56 are driven to rotate by the second rotating rod 53, and the stirring rod 54 fully stirs the concrete when rotating; when the spiral blade 55 rotates, it can not only stir the concrete, but also dredge the discharge when discharging, and the pitch of the spiral blade 55 gradually increases from top to bottom, and at the discharge During the material feeding process, the spiral blade 55 conveys the concrete more and more sparsely, which is convenient for orderly discharge; the scraper rod 56 scrapes off the residual material on the inner wall of the mixing tank 5 when rotating, which can not only reduce the waste of concrete, but also prevent the residual material from being mixed with the concrete of the next feeding, affecting the quality of the concrete, and it is easy to solidify for a long time, which is inconvenient to clean; bubbles mixed in the concrete are easy to produce air holes during pouring, resulting in defects in the formation of the concrete slab. By setting a shaking operation, defoaming is carried out. When shaking is required, the fastening nut 25 is rotated to the end away from the first push plate 22, so that the first push plate 22 has enough movement space when driving the second push plate 36 to facilitate the shaking of the mold 3;The first motor 33 is turned on, and the first rotating rod 35 is driven to rotate by the first motor 33, and the first rotating rod 35 drives the elliptical block 34 to rotate. When the long semi-axis of the elliptical block 34 is vertical, the first spring 23 and the second spring 37 are both in a balanced state. When the long semi-axis of the elliptical block 34 is horizontal, the first spring 23 is compressed, the second spring 37 is extended, and the second push plate 36 pushes the mold 3, and then the elliptical block 34 continues to rotate. Under the action of the first spring 23 and the second spring 37, the first push plate 22 and the second push plate 36 are reset, and the first push plate 22 pushes the mold 3, thereby realizing the mold 3. It has the function of shaking; after standing for a period of time, the concrete slab is formed and needs to be cured. During the curing process, it needs to be sprayed. Water is transported to the water storage box 63 through the water inlet pipe 64, and then sprayed on the concrete slab through the guide groove 66 to achieve a wide range of curing. Driven by the electric guide rail 4 and the reciprocating screw 42, the concrete slab is cured as a whole. When taking the material, the fastening nut 25 is rotated to one end close to the first push plate 22, so that the first push plate 22 is fixed, and the second push plate 36 is driven to hit the mold 3, so that the mold 3 is separated from the concrete slab, which is convenient for taking out the concrete slab. ;
