Technical Field
[0001] This application relates to the technical field of self-compacting concrete construction, and in particular to a self-compacting concrete pouring device and method. Background Technology
[0002] In the construction industry, concrete pouring is an important construction process. However, traditional concrete pouring methods often have some problems, such as uneven pouring and difficulty in removing air bubbles. These problems can affect the strength and durability of concrete.
[0003] Self-compacting concrete is a type of concrete with high fluidity and stability. It can fill the formwork and achieve a compacted state under its own weight and vibration. The advantages of this type of concrete are that it has good workability, high strength and durability, and can reduce noise and dust during construction.
[0004] However, existing self-compacting concrete pouring devices still have some problems. For example, when pouring concrete blocks for bridges, if a vibrator is used, it is necessary to vibrate each section separately, which not only consumes a lot of manpower and resources, but also affects the construction efficiency and quality of the concrete. Summary of the Invention
[0005] In order to demonstrate that the self-compacting pouring of concrete blocks can be achieved in a time-saving and labor-saving manner, this application provides a self-compacting concrete pouring device and method.
[0006] Firstly, this application provides a self-compacting concrete pouring device, which adopts the following technical solution:
[0007] A self-compacting concrete pouring device includes a vibration device, which comprises a housing, a vibrating plate, and a vibration motor. When the housing is horizontally positioned, the bottom surface of the housing is missing. A vibration groove is formed on the side wall of the housing. The vibrating plate is located inside the vibration groove and is fitted against the side wall of the housing. Multiple vibrating plates are provided and are symmetrically arranged along the center line of the housing. The vibrating plates are slidably connected to the housing, and the sliding direction of the vibrating plates is along the direction of mutual approach or distance. The vibration motor is fixedly connected to the housing and the vibrating plates respectively. A support rod is hinged to the vibrating plate. The support rod passes through the side wall of the housing and is hinged to a drive rod. A first spring is ringed on the support rod. One end of the first spring abuts against the housing, and the other end abuts against the drive rod. A buffer assembly for damping the vibration of the vibrating plate is provided on the housing.
[0008] By adopting the above technical solution, when casting concrete blocks for bridges, due to the large quantity, self-compacting casting needs to be carried out in a decentralized manner. At this time, the vibrating device is placed on the outside of the concrete block mold, the drive rod is moved to press the vibrating plate against the side wall of the mold, and the vibrating motor is started. Because the vibrating plate has a large area in contact with the side wall of the mold, not only is the vibration area large, but continuous vibration can also be carried out at the same time as casting. This is faster and has a better self-compacting effect than using a vibrator after casting, and does not affect the casting speed. Continuous casting can be achieved. The buffer component can provide cushioning when pushing the vibrating plate and play a shock-absorbing role when the vibrating plate is working.
[0009] Optionally, the buffer assembly includes a hinge rod and a hinge seat. There are two hinge rods, one end of which is hinged to the hinge seat, and the other ends are far apart from each other. A drive rod is arranged along the central axis of the two hinge rods and is rotatably connected to the hinge seat. There are two support rods, which are symmetrically arranged along the axis of the drive rod and are hinged to the hinge rods.
[0010] By adopting the above technical solution, the drive rod is rotated and connected to the hinge seat. Since the hinge rod does not rotate, the drive rod will push the hinge rod to move towards the side wall of the outer shell. At the same time, the hinge rod will push the support rod to move towards the vibrating plate, thereby pushing the vibrating plate to fit against the concrete block mold and against the outer wall of the mold. The first spring on the support rod abuts against the side wall of the outer shell and the hinge rod respectively, which can play a shock absorption effect when the vibrating plate is working.
[0011] Optionally, the buffer assembly further includes a connecting rod, one end of which is fixedly connected to the housing, a drive rod passing through the connecting rod and threadedly connected to the connecting rod, and a second spring being provided on the drive rod, one end of which abuts against the hinge seat and the other end of which abuts against the connecting rod.
[0012] By adopting the above technical solution, the drive rod and the connecting rod are threaded together, which can maintain the stability of the drive rod and prevent the drive rod from shaking. At the same time, the second spring on the drive rod can play a buffering role when the vibrating plate vibrates, reducing the vibration between the connecting rod and the hinge rod.
[0013] Optionally, a vibration block is slidably connected to the end of the vibration plate away from the outer shell. The sliding direction of the vibration block is along the direction of approaching or away from the vibration plate. Multiple vibration blocks are provided, and the multiple vibration blocks are spaced apart along the side wall of the outer shell.
[0014] By adopting the above technical solution, when the vibrating block encounters a concrete block mold with an arc shape, it can slide more closely toward the outer wall of the mold, thereby making the vibration effect of the mold better.
[0015] Optionally, a buffer pad is fixed to the side of the vibrating block away from the vibrating plate.
[0016] By adopting the above technical solution, the buffer pad can reduce the wear of the vibration block on the outer wall of the mold.
[0017] Optionally, a mixing box is fixed above the vibration device, and a feed inlet is provided on the mixing box. A mixing rod is rotatably connected inside the mixing box. The rotation axis of the mixing rod is set perpendicular to the concrete pouring direction, and mixing blades are fixed on the mixing rod circumferentially.
[0018] By adopting the above technical solution, the concrete material is first poured into the mixing box. The mixing roller and mixing fan blade can mix the concrete more evenly. After entering the mold, it is more conducive to the self-compacting of the concrete through its own gravity and vibration.
[0019] Optionally, multiple rotating plates are fixed to the end of the stirring rod, and the multiple rotating plates are spaced apart along the circumference of the stirring rod, and the rotating plates are attached to the side wall of the mixing box.
[0020] By adopting the above technical solution, the rotating plate rotates in contact with the inner wall of the mixing box while the mixing roller rotates, which can scrape off the inner wall of the mixing box and prevent concrete from sticking to the side wall of the mixing box, thus avoiding waste of raw materials.
[0021] Optionally, a guide plate is fixed inside the mixing box, and the end of the guide plate near the vibration device retracts towards the middle.
[0022] By adopting the above technical solution, after the concrete enters the mixing box, it is poured into the concrete block mold through the guide plate, which can increase the smoothness of the concrete flow. At the same time, the guide plate shrinks in the middle, which can adapt to molds of different diameters and facilitate the pouring of concrete.
[0023] Optionally, the guide plate is provided with an opening and closing assembly, which includes a rotating rod and a tilting blade. The rotating rod is fixedly connected to the tilting blade, and the rotating rod passes through the guide plate and is rotatably connected to the guide plate. The rotation axis of the rotating rod is perpendicular to the concrete pouring direction.
[0024] By adopting the above technical solution, when the concrete is first poured into the mixing box, the opening and closing component is closed, that is, the flipping blade is set parallel to the guide plate port. After the concrete is mixed in the mixing box to a certain extent, the opening and closing component is opened, that is, the rotating rod is rotated to rotate the flipping blade to a state that is not parallel to the guide plate port, and the concrete is poured into the mold.
[0025] Secondly, this application provides a method for a self-compacting concrete pouring device, which adopts the following technical solution:
[0026] A method for a self-compacting concrete pouring device includes the following steps:
[0027] S1. Place the vibration device on the outer periphery of the concrete block mold;
[0028] S2. Adjust the drive rod to fit the vibrating plate and vibrating block against the outer wall of the concrete block mold;
[0029] S3. Pour the concrete into the mixing tank and rotate the mixing roller to mix the concrete.
[0030] S4. Start the opening and closing device to pour the mixed concrete into the mold of the concrete module.
[0031] S5. Start the vibration motor to perform self-compacting vibration on the concrete block mold.
[0032] In summary, this application includes at least one of the following beneficial technical effects:
[0033] 1. When the drive rod is rotated, the connecting rod can increase the stability of the drive rod, and the second spring on the drive rod can provide cushioning for the drive rod when it rotates;
[0034] 2. The support rod and the hinge rod are hinged together, which not only provides support for the vibrating plate, but the first spring on the support rod can also play a role in damping the vibration of the hinge rod;
[0035] 3. When the vibrating block encounters a curved concrete block mold, it can fit more closely to the outer wall of the mold, thus making the vibration effect better. Attached Figure Description

The ground of the vibrating device 1 is missing, and the top surface of the mixing box 6 is provided with a feed inlet 61.
[0045] refer to Figure 2 Inside the mixing tank 6, a mixing roller 62 is rotatably connected. The rotation axis of the mixing roller 62 is set perpendicular to the concrete pouring direction. A mixing blade 621 is fixed circumferentially on the mixing roller 62. The mixing blade 621 is spiral. There are two mixing rollers 62, which are spaced apart horizontally. The mixing blades 621 on the two mixing rollers 62 cooperate with each other to mix the concrete more thoroughly, making the concrete flowing into the concrete block mold more uniform and dense. A rotary motor 622 for driving the mixing roller 62 to rotate is fixed on the outer wall of the mixing tank 6.
[0046] Two rotating plates 623 are fixed at both ends of the mixing roller 62. The two rotating plates 623 are spaced apart around the circumference of the mixing roller 62 and are set against the side wall of the mixing box 6. The rotating plates 623 have beveled surfaces along the radial direction of the mixing roller 62, which can scrape the inner wall of the mixing box 6 when the mixing roller 62 is mixing concrete, so as to reduce the adhesion of concrete to the inner wall of the mixing box 6.
[0047] refer to Figure 2 and Figure 3Inside the mixing chamber 6, near the vibrating device 1, there is a guide plate 7. The guide plate 7 is square-shaped, meaning it tapers towards the center from the end near the vibrating device 1, which allows the concrete inside the mixing chamber 6 to flow more smoothly. On the guide plate 7, near the vibrating device 1, there is an opening and closing assembly 8. The opening and closing assembly 8 includes a rotating rod 81, a tilting blade 82, a driving gear 83, a driven gear 84, a transmission chain 85, and a servo motor 86.

A vibration groove 111 is provided on the side wall of the housing 11. The vibrating plate 12 is located inside the vibration groove 111 and is attached to the side wall of the housing 11. There are two vibrating plates 12, which are symmetrically arranged along the center line of the housing 11. Since the vibration device 1 is symmetrically arranged along its own center line, for ease of explanation, one side of the vibration device 1 is used as an example. The vibration motor 13 is fixed on the side wall of the housing 11. At the same time, the vibration motor 13 is also electrically connected to the vibrating plate 12. The vibrating plate 12 is slidably connected relative to the housing 11. The sliding direction of the two vibrating plates 12 is along the direction of approaching or moving away from each other.
[0049] Two support rods 2 are fixed on the vibrating plate 12. A buffer assembly 4 and a drive rod 3 are mounted on the outer shell 11. The buffer assembly 4 includes a hinge rod 41, a hinge seat 42, and a connecting rod 43. The connecting rod 43 is L-shaped, with one end fixedly connected to the side wall of the outer shell 11. Two hinge rods 41 are provided, with the two support rods 2 and the two hinge rods 41 arranged symmetrically along the connecting rod 43. The support rods 2 penetrate the side wall of the outer shell 11 and are hinged to the hinge rods 41. A first spring 21 is looped around the support rod 2, with one end abutting against the outer shell 11 and the other end abutting against the hinge rod 41. A hinge shaft 4 is fixed on the hinge seat 42. 21. One end of each of the two hinge rods 41 is hinged to the hinge shaft 421, and the other ends of the two hinge rods 41 are far apart from each other.
