Description

Technical Field

[0001] This invention relates to the field of precast floor slab manufacturing equipment, specifically to a molding device and method for producing precast floor slabs. Background Technology

[0002] Precast concrete slabs are generally manufactured in factories using standardized and mechanized methods, while traditional cast-in-place concrete requires on-site molding, pouring, and curing, which takes longer and is less efficient.

[0003] In the existing production process of precast concrete floor slabs, concrete needs to be transported into the mold through concrete pouring equipment. To avoid pouring concrete onto the top surface of the mold and to avoid subsequent cleaning of the top surface of the mold, the discharge port of the pouring equipment is generally smaller than the width of the mold. Due to the poor fluidity of concrete, the edge area of ​​the mold is difficult to be fully filled with concrete, affecting the production quality of the precast floor slab. At this time, it is necessary to manually fill the edge of the mold with concrete, which increases labor costs, slows down the entire production rhythm, and seriously affects production efficiency. Furthermore, after the concrete is filled, it is necessary to manually use a vibrator to vibrate and expel air from the concrete, which can easily affect the efficiency of the equipment in producing and shaping the precast floor slab.

[0017] Preferably, the feeding mechanism includes a first cylinder, the driving end of the first cylinder is connected to a C-shaped plate, a stabilizing rod is fixed on one side of the bottom of the C-shaped plate, and a casting device is slidably connected to one side of the stabilizing rod.

[0018] The C-shaped plate is connected to a second motor on one side. The drive end of the second motor is connected to a threaded rod.

The bottom of the pouring equipment is connected to a first motor, a first telescopic component, a fourth gear, and a push block. A timer is installed at the bottom of the pouring equipment. The timer is electrically connected to the first motor and the second motor.

[0019] Preferably, the method of using the molding device for precast floor slab production includes the following steps:

[0020] S1: The position of the feeding plate is adjusted by the feeding mechanism, and then concrete is injected into the mold body by the pouring equipment. Then, the filling vibration component is rotated by the transmission component to fill the edge of the mold body, so that the guide column moves along the C-shaped guide groove. When the guide column moves to the first corner of the C-shaped guide groove, the feeding plate starts to move. At the same time, the transmission component is stopped by the timer.

[0021] S2: When the guide column moves to the second corner of the C-shaped guide groove, the feeding plate stops moving. At this time, there is a gap between the vibrating column and the inner wall of the mold body. Then, the transmission component is controlled by the timer to work, so that the filling vibration component rotates. When the guide column moves to the end of the C-shaped guide groove, the L-shaped block squeezes the bending rod to make the bending rod descend, so that the limit component disengages from the lifting slider, so that the lifting slider rises, thereby changing the working state of the filling vibration component and making the vibrating column located in the concrete. At this time, the feeding plate continues to move, so that the T-shaped rod squeezes the C-shaped plate, thereby changing the working state of the transmission component and making the filling vibration component reciprocate.

[0022] S3: During the return stroke of the material plate, the filling vibration component reciprocates, and the vibration column vibrates to expel air from the concrete.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] In this invention, the transmission component and T-shaped rod work together to achieve flexible switching of the working state of the transmission component. Before the transmission component changes its working state, it can drive the first arm, screed, and vibrating column to rotate 360° in all directions, which facilitates the precise and comprehensive filling of concrete to all corners of the edges, ensuring the uniformity and integrity of the filling and avoiding insufficient filling at the edges. After the transmission component changes its working state, it can make the first arm, screed, and vibrating column reciprocate. In this motion mode, the vibrating column can swing back and forth regularly inside the concrete. The vibration generated when the vibrating column is started, and the vibration will promote the expulsion of air inside the concrete during the swinging process, which can effectively reduce structural defects caused by air bubbles inside the concrete. By switching between the two working states of the transmission component, not only can the smoothing and filling of concrete be completed efficiently, but the air in the concrete can also be vented, which greatly improves the efficiency and quality of the entire construction process.

[0025] In this invention, the combined use of a filling vibration component, a limiting component, and an L-shaped block enables flexible switching of the screed's state. Before changing the screed's state, it smooths and fills the edge area of ​​the mold body, ensuring that the concrete at the edges is densely filled and the surface is flat. This effectively avoids problems such as uneven edges or insufficient filling that may affect the subsequent construction quality. After changing the screed's state, it will switch to a vertical position. At this time, the vibration column can be inserted into the concrete, and the screed in this state can still make just contact with the concrete, thereby allowing air inside the concrete to be effectively expelled. This avoids quality problems such as insufficient strength of the precast floor slab due to residual air, thus effectively ensuring the density and stability of the precast floor slab and improving the construction quality.

[0026] In this invention, the combined use of a timer, a feeding mechanism, and a smoothing vibration mechanism can effectively control the start and stop of the feeding mechanism and the smoothing vibration mechanism. This allows for precise setting of the start and stop times of the feeding mechanism, as well as the start, stop, and continuous operation times of the smoothing vibration mechanism. This ensures that each step can be carried out in an orderly manner at the most appropriate time, greatly improving work efficiency. Attached Figure Description

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Please see Figures 1 to 15 The present invention provides a technical solution: a molding device for producing precast floor slabs, including a mold body 1 and a feeding mechanism 2, the feeding mechanism 2 being located above the mold body 1, and C-shaped guide grooves 11 being provided on both sides of the top of the mold body 1.

[0045] The bottom of the feeding mechanism 2 is connected to a symmetrically distributed smoothing vibration mechanism 3. The smoothing vibration mechanism 3 is used to fill the concrete to the edge area of ​​the mold and to expel the air in the concrete. The smoothing vibration mechanism 3 includes a first motor 31 set at the bottom of the feeding mechanism 2. The drive end of the first motor 31 is connected to a transmission component. The bottom of the transmission component is connected to a filling vibration component. The transmission component is used to switch the working state of the filling vibration component.

[0046] In this embodiment, as Figures 7 to 10 As shown, the transmission assembly includes a fixed cylinder 32 connected to the drive end of the first motor 31. A first spring 33 is connected to the lower surface inside the fixed cylinder 32. A lifting rod 34 is connected to the top of the first spring 33. The lifting rod 34 is slidably connected to the fixed cylinder 32. A first gear 35 is connected to the top of the lifting rod 34. A second gear 38 is connected to the top of the first gear 35. An L-shaped rod 36 is rotatably connected to the top of the first gear 35. The L-shaped rod 36 is located between the first gear 35 and the second gear 38. A vertical plate 37 is fixed to the end of the L-shaped rod 36 away from the first gear 35. The vertical plate 37 is slidably connected to the groove at the bottom of the feeding mechanism 2. It should be noted that the lifting rod 34 can be reset by the elastic force of the first spring 33. The first motor 31 drives the fixed cylinder 32 and the lifting rod 34 to rotate, thereby driving the first gear 35 and the second gear 38 to rotate.

[0047] The bottom of the feeding mechanism 2 is provided with symmetrically distributed T-shaped rods 5. A push block 51 is fixed to the side of the T-shaped rod 5 near the first motor 31. The bottom of the push block 51 is slidably connected to the feeding mechanism 2, and the push block 51 cooperates with the L-shaped rod 36. It should be noted that: the bottom side of the L-shaped rod 36 is provided with a fourth inclined edge, and the top side of the push block 51 is provided with a fifth inclined edge. Through the cooperation of the fourth and fifth inclined edges, the push block 51 can squeeze the L-shaped rod 36, thereby causing the L-shaped rod 36 to rise, which in turn can drive the first gear 35 and the second gear 38 to rise.

[0048] The bottom of the feeding mechanism 2 is rotatably connected to a first telescopic member 311. The bottom end of the first telescopic member 311 is connected to a third gear 310. The top of the third gear 310 is rotatably connected to a C-shaped rod 39. One end of the C-shaped rod 39 is rotatably connected to a second gear 38.

[0049] The bottom of the feeding mechanism 2 is rotatably connected to a fourth gear 312, which meshes with the first gear 35. The bottom of the fourth gear 312 is connected to a first half-gear 313, which engages with the first gear 35. The bottom of the first half-gear 313 is connected to a second half-gear 314, which engages with the third gear 310. It should be noted that the first telescopic member 311 improves the stability of the third gear 310. The C-shaped rod 39 allows the second gear 38 to drive the third gear 310 upwards, thus engaging the first gear 35 with the first half-gear 313, and simultaneously engaging the third gear 310 with the second half-gear 314. When the first gear 35 is in its initial state, it engages with the fourth gear 312, thereby driving the fourth gear 312 to rotate, which in turn drives the filling vibration assembly to rotate.

[0050] In this embodiment, as Figure 6 , Figure 8 , Figure 10 and Figure 13 As shown, the filling vibration assembly includes a fixing block 315 connected to the bottom of the second half gear 314. A second spring 316 is connected to one side of the fixing block 315. One end of the second spring 316 is connected to a slide rod 317. One end of the slide rod 317 is slidably connected to a hole provided in the fixing block 315. The bottom of the other end of the slide rod 317 is rotatably connected to a stepped column 318. The bottom of the stepped column 318 is fixedly connected to a first arm 319. A locking assembly is connected to one side of the top of the first arm 319. A long rod 320 is fixed to one end of the first arm 319 away from the stepped column 318. A smearing plate 322 is rotatably connected to one side of the bottom of the long rod 320. A vibration column 323 is connected to one side of the smearing plate 322 near the inner wall of the mold body 1. A connecting rod 324 is rotatably connected to the top of the smearing plate 322. A lifting slider 325 is rotatably connected to the top of the connecting rod 324. It should be noted that: the elastic force of the second spring 316 can reset the slide bar 317, and the fourth gear 312 can drive the fixed block 315 and the slide bar 317 to rotate, thereby pushing the first arm 319 to move, which in turn can move the long rod 320 and the slurry plate 322 to fill the concrete to the edge area of ​​the mold body 1. The slurry plate 322 and the inner wall of the mold body 1 have an angle, and the angle is acute. When the lifting slider 325 moves up, it can drive the slurry plate 322 to rotate 90° through the connecting rod 324, so that the vibrating column 323 is inserted into the concrete. At this time, the vibration column 323 can be activated to expel the air in the concrete, and during the return stroke of the feeding mechanism 2, the vibration column 323 can swing back and forth, so that the vibration column 323 can fully vent the concrete.

[0051] In this embodiment, as Figure 6 , Figure 8 , Figure 12 , Figure 13 and Figure 14 As shown, a limiting component is connected to one side of the bottom of the long rod 320. The limiting component cooperates with the lifting slider 325. A limiting groove is provided on one side of the long rod 320. The groove body is slidably connected to the lifting slider 325. A second cylinder is connected to the top of the limiting groove body. The second cylinder consists of a cylinder barrel 321 and a piston rod 326. A third spring 328 is connected to the bottom of the piston rod 326. A guide rod 327 is slidably connected to the inner wall of the piston rod 326. The bottom of the guide rod 327 is connected to the lifting slider 325. It should be noted that the elastic force of the third spring 328 can cause the lifting slider 325 and the guide rod 327 to rise, thereby causing the connecting rod 324 to rotate, which in turn causes the squeegee 322 to rotate 90°. The second cylinder can cause the lifting slider 325 to fall, thereby allowing the limiting component to cooperate with the lifting slider 325 to limit the lifting slider 325.

[0052] The top of the lifting slider 325 is connected to the second telescopic member 335, and the top of the second telescopic member 335 is connected to the fixing plate 336. Two guide posts 337 are rotatably connected to the bottom of the fixing plate 336. The guide posts 337 are located on both sides of the locking assembly. The bottom end of the guide post 337 passes through the first arm 319 and engages with the groove of the C-shaped guide groove 11 and the outer wall of the mold body 1. It should be noted that when the lifting slider 325 returns to its top position, the second telescopic member 335 and the fixing plate 336 drive the guide post 337 to rise, thereby disengaging the guide post 337 from the C-shaped guide groove 11. One guide post 337 remains within the groove of the C-shaped guide groove 11, while the other guide post 337 engages with the outer wall of the mold body 1.

[0053] In this embodiment, as Figures 13 to 15 As shown, the limiting assembly includes a first telescopic cylinder 331 connected to one side of the bottom of the long rod 320. A fourth spring 332 is connected to one side of the inside of the first telescopic cylinder 331. A first telescopic rod 333 is connected to one side of the fourth spring 332. One end of the first telescopic rod 333 has a first bevel at its top. One end of the first telescopic rod 333 passes through the long rod 320 and engages with a slot 3251 on one side of the lifting slider 325. The other end of the first telescopic rod 333 passes through the first telescopic cylinder 331 and connects to a moving block 334. It should be noted that the elastic force of the fourth spring 332 allows the first telescopic rod 333 to enter the slot 3251, thereby limiting the position of the lifting slider 325. The first bevel facilitates the lifting slider 325 pressing the first telescopic rod 333, causing the first telescopic rod 333 to retract.

[0054] A long rod 320 is slidably connected to a bent rod 329 on one side. The top end of the bent rod 329 has a second inclined edge, and a pressing block 330 is fixed to one side of the bottom of the bent rod 329. The pressing block 330 cooperates with a moving block 334. It should be noted that the pressing block 330 has a sixth inclined edge on one side of its bottom, and the moving block 334 has a seventh inclined edge on one side of its top. The sixth and seventh inclined edges cooperate to facilitate the pressing block 330 pressing the moving block 334, causing the moving block 334 to move. A second slider is fixed to one side of the bottom of the bent rod 329, and a second groove adapted to the second slider is provided on one side of the long rod 320.

[0055] On the top side of the mold body 1 away from the first motor 31, symmetrically distributed L-shaped blocks 4 are installed. A third inclined edge 41 is provided on the outer side of the top of each L-shaped block 4, which engages with the second inclined edge. It should be noted that the engagement of the third inclined edge 41 with the second inclined edge facilitates the bending rod 329 pressing the L-shaped block 4, thereby causing the bending rod 329 and the lowering block 330 to descend, which in turn causes the moving block 334 to move. The moving block 334 then drives the first telescopic rod 333 to move, thereby disengaging the first telescopic rod 333 from the slot 3251.

[0056] In this embodiment, as Figures 10 to 13 As shown, the locking assembly includes a second telescopic cylinder 341 connected to the top of the first arm 319. A fifth spring 342 is connected to the upper surface inside the second telescopic cylinder 341. The bottom of the fifth spring 342 is connected to a second telescopic rod 343. The bottom end of the second telescopic rod 343 passes through the first arm 319 and engages with the upper surface of the mold body 1. The top end of the second telescopic rod 343 passes through the second telescopic cylinder 341 and connects to the second arm 338. A plurality of limiting posts 339 are fixed to the bottom of one end of the second arm 338. One end of the second arm 338 is rotatably connected to the top of the stepped post 318. A plurality of limiting grooves 340 are provided on the outer side of the top of the larger diameter end of the stepped post 318. The grooves of the limiting grooves 340 engage with the limiting posts 339. It should be noted that the elastic force of the fifth spring 342 can cause the second telescopic rod 343 to descend, thereby causing the second arm 338 and the limiting post 339 to descend, and then causing the limiting post 339 to enter the limiting groove 340, thereby restricting the rotation of the stepped post 318 and making it easier for the first arm 319 to swing back and forth. The second telescopic rod 343 pressing the mold body 1 can cause the second telescopic rod 343 to rise, thereby causing the limiting post 339 to disengage from the limiting groove 340, allowing the stepped post 318 to rotate.

[0057] In this embodiment, as Figures 1 to 6 As shown, the feeding mechanism 2 includes a first cylinder 21, the drive end of the first cylinder 21 is connected to a C-shaped plate 22, a stabilizing rod 27 is fixed on one side of the bottom of the C-shaped plate 22, and a pouring device 25 is slidably connected to one side of the stabilizing rod 27.

[0058] A second motor 23 is connected to one side of the C-shaped plate 22. The drive end of the second motor 23 is connected to a threaded rod 24, which mates with a threaded hole on one side of the casting device 25. A discharge plate 26 is connected to one side of the casting device 25. A first motor 31, a first telescopic component 311, a fourth gear 312, and a push block 51 are connected to the bottom of the casting device 25. A timer 6 is installed at the bottom of the casting device 25, and the timer 6 is electrically connected to the first motor 31 and the second motor 23. It should be noted that the first cylinder 21 can drive the C-shaped plate 22 to rise and fall, thereby controlling the height of the discharge plate 26. The second motor 23 drives the threaded rod 24 to rotate, thereby moving the casting device 25 and the discharge plate 26 to achieve uniform material discharge. The casting device 25 is existing technology and will not be described in detail here. A first slider is fixed to the top of the push block 51, and a first groove adapted to the first slider is provided at the bottom of the casting device 25.

[0059] In this embodiment, as Figures 1 to 15 As shown, a method of using a molding device for producing precast floor slabs includes the following steps:

[0060] S1: Upon startup, the first cylinder 21 lowers the pouring equipment 25 and the material feeding plate 26, causing the guide column 337 to engage with the C-shaped guide groove 11 and the outer wall of the mold body 1. Simultaneously, the second telescopic rod 343 presses against the mold body 1, causing it to rise and disengage the limiting column 339 from the limiting groove 340, allowing the stepped column 318 to rotate. Then, the pouring equipment 25 injects concrete into the mold body 1. Subsequently, the first motor 31 drives the fixed cylinder 32 and the lifting rod 34 to rotate, which in turn drives the first gear 35 to rotate, which in turn drives the fourth gear 312 to rotate. The fourth gear 312 then drives the fixed block 315 and the sliding rod 317 to rotate. This allows the first arm 319 to move, which in turn moves the long rod 320 and the squeegee 322, enabling the concrete to be filled into the edge area of ​​the mold body 1. At the same time, the guide post 337 moves along the C-shaped guide groove 11. When the guide post 337 moves to the first corner of the C-shaped guide groove 11, the squeegee 322 rotates 90° with the first arm 319, making it easier for the squeegee 322 to smooth the concrete. At this time, the timer 6 sends a signal to stop the first motor 31 from working. At the same time, the second motor 23 drives the threaded rod 24 to rotate, thereby driving the pouring equipment 25 and the material feeding plate 26 to move, which in turn drives the smoothing vibration mechanism 3 to move, achieving uniform material feeding while filling the edge area.

[0061] S2: When the guide post 337 moves to the second corner of the C-shaped guide groove 11, the unloading plate 26 stops moving. At this time, there is a sufficiently large gap between the vibrating post 323 and the inner wall of the mold body 1. At this time, the timer 6 controls the first motor 31 to work, thereby causing the first arm 319 and the squeegee 322 to rotate. After rotating 90°, when the guide post 337 is at the tail end of the C-shaped guide groove 11, the L-shaped block 4 presses the bending rod 329, causing the bending rod 329 and the lower pressure block 330 to descend, thereby causing the moving block 334 to move. The moving block 334 drives the first telescopic rod 333 to move, thereby causing the first telescopic rod 333 to disengage from the slot 3251. At this time, through The elastic force of the third spring 328 can cause the lifting slider 325 and guide rod 327 to rise, thereby causing the connecting rod 324 to rotate, which in turn causes the trowel plate 322 to rotate 90°, allowing the vibrating column 323 to be inserted into the concrete. At this time, the vibrating column 323 is turned on to vent the concrete. At this time, the material feeding plate 26 continues to move, which causes the T-shaped rod 5 to press the C-shaped plate 22, thereby causing the T-shaped rod 5 and push block 51 to move, which in turn presses the L-shaped rod 36 to rise, thereby driving the first gear 35, the second gear 38 and the third gear 310 to rise, so that the first gear 35 engages with the first half gear 313, and at the same time the third gear 310 engages with the second half gear 314.

[0062] S3: During the return stroke of the unloading plate 26, the second telescopic rod 343 is lowered by the elastic force of the fifth spring 342, thereby lowering the second arm 338 and the limiting post 339. The limiting post 339 then enters the limiting groove 340, thus restricting the rotation of the stepped post 318. The first motor 31 is controlled by the timer 6 to work, thereby causing the first arm 319, the slurry plate 322 and the vibrating post 323 to reciprocate. The vibrating post 323 vibrates, which can fully expel the air in the concrete. When the unloading plate 26 returns to the initial state, the lifting slider 325 is lowered by the first cylinder 21, and the first telescopic rod 333 restricts the position of the lifting slider 325, thereby resetting the slurry plate 322. The first arm 319 is rotated by the first motor 31 until it returns to the initial state.
