Description

Technical Field

[0001] The present invention relates to the field of precast floor slab manufacturing equipment, and particularly to a forming device and a using method for precast floor slab production. Background Art

[0002] Concrete precast floor slabs are generally processed and produced in factories in a standardized and mechanized manner, while traditional cast-in-place concrete requires on-site formwork making, on-site pouring, and on-site curing at the construction site, which takes a long time and has low efficiency.

[0003] During the production process of existing concrete precast floor slabs, it is necessary to transport concrete into the mold through a concrete pouring device. In order to prevent the pouring device from pouring the poured 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 device is generally smaller than the width of the mold. Since the concrete itself has poor fluidity, it is difficult for the concrete to fully fill the edge area of the mold, which affects the production quality of the precast floor slab. At this time, it is necessary to manually fill the concrete into the mold edge, which increases the labor cost and slows down the entire production rhythm, seriously affecting the production efficiency; and after the concrete filling is completed, it is necessary to manually use a vibrating rod to vibrate to discharge the air in the concrete, which easily affects the efficiency of the device for forming the precast floor slab.

[0019] Preferably, a method for using the forming device for precast floor slabs includes the following steps:

[0020] S1: Adjust the position of the blanking plate through the blanking mechanism, then inject concrete into the mold body through the pouring equipment, and then rotate the filling and vibrating assembly through the transmission assembly to achieve the filling of the edge of the mold body, so that the guide post moves along the C-shaped guide groove. When the guide post moves to the first corner of the C-shaped guide groove, the blanking plate starts to move, and at the same time, the transmission assembly is controlled to stop working by the timer;

[0021] S2: When the guide post moves to the second corner of the C-shaped guide groove, the blanking plate stops moving. At this time, there is a gap between the vibrating post and the inner wall of the mold body. Then, the transmission assembly is controlled to work by the timer, so that the filling and vibrating assembly rotates. When the guide post 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 limiting assembly disengages from the lifting slider, so that the lifting slider rises, thereby changing the working state of the filling and vibrating assembly, making the vibrating post located in the concrete. At this time, the blanking plate continues to move, so that the T-shaped rod squeezes the C-shaped plate, thereby changing the working state of the transmission assembly, and making the filling and vibrating assembly perform reciprocating motion;

[0022] S3: During the return process of the blanking plate, the filling and vibrating assembly performs reciprocating motion, and the vibrating post vibrates to discharge the air in the concrete.

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

[0024] In the present invention, through the combined use of the transmission assembly and the T-shaped rod, the flexible switching of the working state of the transmission assembly is realized. Before the transmission assembly changes the working state, it can drive the first arm rod, the screed plate and the vibrating post to perform a full-range 360° rotation, which is convenient for accurately and comprehensively filling the concrete into every corner of the edge, ensuring the uniformity and integrity of the filling, and avoiding situations such as insufficient filling in the edge part. After the transmission assembly changes the working state, it can make the first arm rod, the screed plate and the vibrating post perform reciprocating motion. In this motion mode, the vibrating post can swing back and forth regularly inside the concrete. The vibrating post starts to vibrate, and the vibrating post will promote the air in the concrete to be discharged during the swinging process, which can effectively reduce the structural defects caused by the presence of air bubbles in the concrete. By switching the two working states of the transmission assembly, not only can the screeding and filling work of the concrete be efficiently completed, but also the concrete can be exhausted, greatly improving the efficiency and quality of the entire construction process;

[0025] In the present invention, through the combined use of a filling vibration assembly, a limiting assembly, and an L-shaped block, the flexible switching of the state of the screed plate is achieved. Before changing the state of the screed plate, the screed plate can level and fill the edge area of the mold body, ensuring that the concrete at the edge is filled densely and the surface is flat, effectively avoiding problems such as unevenness or insufficient filling at the edge that may affect the subsequent construction quality. After changing the state of the screed plate, the screed plate will switch to a vertical state. At this time, the vibration column can be inserted into the concrete smoothly, and the screed plate in this state can still just contact the concrete, so that the air inside the concrete can be effectively discharged, avoiding quality hazards such as insufficient strength of the precast floor slab caused by air residue, thus effectively ensuring the density and stability of the precast floor slab and improving the construction quality;

[0026] In the present invention, through the combined use of a timer, a blanking mechanism, and a leveling vibration mechanism, the start and stop of the blanking mechanism and the leveling vibration mechanism can be effectively controlled, so that the start and stop times of the blanking of the blanking mechanism can be accurately set, and the start, stop, and continuous working times of the leveling vibration mechanism can be set, ensuring that each link can be carried out orderly at the most appropriate time node, which can greatly improve the work efficiency.

The leveling and vibrating mechanisms 3 include a first motor 31 arranged at the bottom of the feeding mechanism 2. The driving end of the first motor 31 is connected with a transmission component, and the bottom of the transmission component is connected with a filling and vibrating component. The transmission component is used to switch the working state of the filling and vibrating component.

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

The cooperation of the fourth bevel edge and the fifth bevel edge can make the push block 51 squeeze the L-shaped rod 36, so as to make the L-shaped rod 36 rise, and further drive the first gear 35 and the second gear 38 to rise.

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

[0049] The bottom of the blanking mechanism 2 is rotatably connected to a fourth gear 312. The fourth gear 312 is meshed and connected with a first gear 35. The bottom of the fourth gear 312 is connected to a first half gear 313. The first half gear 313 cooperates with the first gear 35. The bottom of the first half gear 313 is connected to a second half gear 314. The second half gear 314 cooperates with a third gear 310.

Through the C-shaped rod 39, the second gear 38 can drive the third gear 310 to rise, so that the first gear 35 cooperates with the first half gear 313. At the same time, the third gear 310 cooperates with the second half gear 314. When the first gear 35 is in the initial state, the first gear 35 cooperates with the fourth gear 312, so that the fourth gear 312 can be driven to rotate by the first gear 35, and then the filling vibration assembly can be driven to rotate.

[0050] In this embodiment, as Figure 6 , Figure 8 , Figure 10 and Figure 13 shown, the filling vibration assembly includes a fixed block 315 connected to the bottom of the second half gear 314.

The bottom of the stepped column 318 is fixedly connected to a first arm rod 319. One side of the top of the first arm rod 319 is connected to a locking assembly. One end of the first arm rod 319 away from the stepped column 318 is fixed with a long rod 320. One side of the bottom of the long rod 320 is rotatably connected to a trowel plate 322. One side of the trowel plate 322 close to the inner wall of the mold body 1 is connected to a vibration column 323. The top of the trowel plate 322 is rotatably connected to a connecting rod 324. The top end of the connecting rod 324 is rotatably connected to a lifting slider 325. It should be noted that: the elastic force of the second spring 316 can reset the slide rod 317. The fourth gear 312 can drive the fixed block 315 and the slide rod 317 to rotate, so that the first arm rod 319 can be pushed to move, and then the long rod 320 and the trowel plate 322 can be moved, realizing the filling of concrete into the edge area of the mold body 1. There is an included angle between the trowel plate 322 and the inner wall of the mold body 1, and the included angle is an acute angle. When the lifting slider 325 moves upward, the trowel plate 322 can be driven to rotate 90° through the connecting rod 324, so that the vibration column 323 is inserted into the concrete. At this time, starting the vibration column 323 can discharge the air in the concrete. And during the return process of the blanking mechanism 2, the vibration column 323 can swing reciprocally, so that the vibration column 323 can fully exhaust the concrete.

The other end of the first telescopic rod 333 passes through the first telescopic cylinder 331 and is connected with a moving block 334. It should be noted that: the elastic force of the fourth spring 332 can make the first telescopic rod 333 enter the clamping groove 3251, so as to limit the position of the lifting slider 325. The first bevel edge can facilitate the lifting slider 325 to squeeze the first telescopic rod 333 to make the first telescopic rod 333 contract.

[0054] One side of the long rod 320 is slidably connected to the bent rod 329. One end of the top of the bent rod 329 is provided with a second bevel edge.

The moving block 334 drives the first telescopic rod 333 to move, so that the first telescopic rod 333 disengages from the card slot 3251.

[0056] In this embodiment, as Figures 10 to 13 shown, the locking assembly includes a second telescopic cylinder 341 connected to the top of the first arm rod 319.

At the bottom of one end of the second arm rod 338, a plurality of limiting columns 339 are fixed. One end of the second arm rod 338 is rotatably connected to the top of the stepped column 318. On the outer side of the top of the larger-diameter end of the stepped column 318, a plurality of limiting grooves 340 are provided, and the groove body of the limiting groove 340 cooperates with the limiting column 339. It should be noted that: the elastic force of the fifth spring 342 can make the second telescopic rod 343 descend, so that the second arm rod 338 and the limiting column 339 descend, and further the limiting column 339 enters the limiting groove 340 to realize the rotation restriction of the stepped column 318, which is more conducive to the reciprocating swing of the first arm rod 319. The second telescopic rod 343 pressing the mold body 1 can make the second telescopic rod 343 rise, so that the limiting column 339 disengages from the limiting groove 340 and the stepped column 318 can rotate.

The threaded rod 24 is matched with the threaded hole arranged on one side of the pouring device 25. One side of the pouring device 25 is connected with a blanking plate 26. The bottom of the pouring device 25 is connected with a first motor 31, a first telescopic member 311, a fourth gear 312 and a pushing block 51. A timer 6 is installed at the bottom of the pouring device 25. 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 lift, so as to control the height of the blanking plate 26. The second motor 23 drives the threaded rod 24 to rotate, so as to drive the pouring device 25 and the blanking plate 26 to move, realizing uniform blanking. The pouring device 25 is an existing technology and will not be elaborated here. A first slider is fixed on the top of the pushing block 51. A first chute adapted to the first slider is arranged at the bottom of the pouring device 25.

[0059] In this embodiment, as Figures 1 to 15 shown, a method for using a forming device for precast floor production includes the following steps:

[0060] S1: When starting to work, first, the first cylinder 21 drives the pouring device 25 and the blanking plate 26 to descend, so that the guide post 337 is matched with the C-shaped guide groove 11 and the outer wall of the mold body 1. At the same time, the second telescopic rod 343 presses the mold body 1, and then the second telescopic rod 343 rises, so that the limit post 339 disengages from the limit groove 340, so that the stepped post 318 can rotate. Then, the concrete is injected into the mold body 1 through the pouring device 25. Subsequently, the first motor 31 drives the fixed cylinder 32 and the lifting rod 34 to rotate, so as to drive the first gear 35 to rotate, and then drive the fourth gear 312 to rotate. The fourth gear 312 drives the fixed block 315 and the slide rod 317 to rotate, so as to be able to push the first arm rod 319 to move, and then the long rod 320 and the troweling plate 322 move, realizing filling the concrete 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 troweling plate 322 rotates 90° along with the first arm rod 319, which is convenient for the troweling plate 322 to level the concrete. At this time, the timer 6 sends a signal to stop the first motor 31. At the same time, the second motor 23 drives the threaded rod 24 to rotate, so as to drive the pouring device 25 and the blanking plate 26 to move, and then drive the leveling and vibrating mechanism 3 to move, realizing uniform blanking and filling operation in the edge area at the same time;

[0061] S2: When the guide post 337 moves to the second corner of the C-shaped guide groove 11, the blanking plate 26 stops moving. At this time, there is a gap with a large enough distance 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, so that the first arm 319 and the screeding plate 322 rotate. After rotating 90°, when the guide post 337 is located at the end of the C-shaped guide groove 11, the L-shaped block 4 squeezes the bending rod 329 to make the bending rod 329 and the pressing block 330 descend, and then makes the moving block 334 move. The moving block 334 drives the first telescopic rod 333 to move, so that the first telescopic rod 333 disengages from the clamping groove 3251. At this time, the elastic force of the third spring 328 can make the lifting slider 325 and the guide rod 327 rise, so that the connecting rod 324 rotates, and then the screeding plate 322 flips 90°, making the vibrating post 323 insert into the concrete. At this time, the vibrating post 323 is turned on to exhaust the concrete. At this time, the blanking plate 26 continues to move, so that the T-shaped rod 5 squeezes the C-shaped plate 22, and then the T-shaped rod 5 and the push block 51 move, squeezing the L-shaped rod 36 to make the L-shaped rod 36 rise, and then being able to drive the first gear 35, the second gear 38 and the third gear 310 to rise, so that the first gear 35 cooperates with the first half gear 313, and at the same time the third gear 310 cooperates with the second half gear 314;

[0062] S3: During the return process of the blanking plate 26, the elastic force of the fifth spring 342 can make the second telescopic rod 343 descend, so that the second arm 338 and the limit post 339 descend, and then the limit post 339 enters the limit groove 340 to realize the rotation restriction of the stepped post 318. The timer 6 controls the first motor 31 to work, so that the first arm 319, the screeding plate 322 and the vibrating post 323 perform reciprocating motions, and the vibrating post 323 vibrates, which can fully exhaust the air in the concrete. When the blanking plate 26 returns to the initial state, the first cylinder 21 makes the lifting slider 325 descend, and the first telescopic rod 333 restricts the position of the lifting slider 325 to realize the reset of the screeding plate 322, and the first motor 31 makes the first arm 319 rotate until it returns to the initial state.
