Description

Technical Field

[0001] This invention relates to the field of concrete pouring technology, and in particular to an integrated green concrete municipal pavement pouring equipment and method. Background Technology

[0002] Green concrete is an inevitable product of the advancement of materials science and technology and the sustainable development of society. It is an advanced civil engineering material with environmental compatibility and self-adaptive properties. Green concrete can be divided into: recycled aggregate concrete, environmentally friendly concrete, etc. It achieves the effects of saving and protecting the environment by replacing some of the concrete with other materials.

[0003] Recycled aggregate concrete refers to concrete made by adding waste concrete, waste bricks, and waste mortar as aggregates to cement mortar. Although this type of concrete is more environmentally friendly, the use of waste materials instead of the original aggregates can lead to uneven mixing during the mixing process, which can affect the quality of the pouring. Summary of the Invention

[0004] To address the problem that uneven mixing and poor casting quality can occur during green concrete mixing due to the use of waste materials instead of original aggregates in existing technologies, this application provides an integrated green concrete municipal pavement casting device, the specific solution of which is as follows.

[0005] A green concrete municipal road integrated pouring equipment includes a pouring track and an aggregate mixer. The pouring track is used to be laid on both sides of the construction area and along the construction area. A pouring frame is slidably installed on the pouring track and can slide along the pouring track. The aggregate mixer is used to mix raw materials and aggregates. The pouring frame is equipped with a pouring mixer for mixing concrete. The pouring frame is also equipped with a pouring pipe that is connected to the pouring mixer and is used to discharge concrete. An inlet pipe is provided between the aggregate mixer and the pouring mixer for feeding concrete mixed by the aggregate mixer into the pouring mixer. A spiral mixing rod is provided inside the inlet pipe, which can drive the concrete to move towards the pouring mixer. One end of the feed pipe is rotatably connected to the aggregate mixer, and the other end of the feed pipe is provided with a connecting rod. The end of the connecting rod away from the feed pipe is connected to the casting frame. When the casting frame moves, it can drive the feed pipe to move. When the feed pipe moves, it can always pass raw materials toward the casting mixer.

[0006] By adopting the above technical solutions, pouring tracks are laid on both sides of the construction area, allowing the pouring frame to slide along the tracks, facilitating the movement of the pouring operation within the construction area; the aggregate mixer mixes the raw materials and aggregates, and the spiral mixing rod in the feed pipe drives the mixed concrete to move towards the pouring mixer, which can further mix to avoid uneven mixing of recycled aggregate concrete and improve the pouring quality; the feed pipe is rotatably connected to the aggregate mixer and connected to the pouring frame through a connecting rod, so that the feed pipe can rotate with the movement of the pouring frame and always supply raw materials to the pouring mixer, ensuring the continuity of the pouring process.

[0007] Optionally, the end of the connecting rod near the feed pipe is ball-jointed with the feed pipe.

[0008] By adopting the above technical solution, the connecting rod and the feed pipe are ball-jointed, which makes the feed pipe more flexible and adjustable when it moves with the casting frame. It can better adapt to the movement of the casting frame, ensure that the feed pipe can always pass raw materials toward the casting mixer when it moves, and avoid damage or interference with the normal feeding of the feed pipe due to the rigid connection between the feed pipe and the connecting rod during movement.

[0009] Optionally, a circulation seat is provided on the pouring frame corresponding to the pouring pipe. The pouring pipe is deformable and fixed on the circulation seat. The circulation seat is movably connected to the pouring frame and circulates along the length of the pouring frame.

[0010] By adopting the above technical solutions, concrete can be poured through the pouring pipe at different locations, expanding the pouring range of concrete and improving pouring efficiency and uniformity.

[0011] Optionally, two casting mixers are provided on the casting frame, with the casting mixers respectively located at both ends of the casting frame along its length. Corresponding aggregate mixers are also provided on both sides of the casting track, and feed pipes are provided between the aggregate mixers and the casting mixers.

[0012] By adopting the above technical solutions and setting up two pouring mixers and aggregate mixers, a larger construction area can be achieved, and the fixation on both sides is more stable, which can further improve the stability and accuracy of construction.

[0013] Optionally, the casting mixer is equipped with a feeding funnel, the interior of which is connected to the interior of the casting mixer. The feeding funnel is positioned corresponding to the nearby feeding pipe, and the feeding pipe is always aligned with the feeding funnel when it moves.

[0014] By adopting the above technical solutions, the feeding funnel can provide a guiding effect for the concrete, allowing the concrete to be more accurately poured into the concrete mixer. Furthermore, through the cooperation between the feeding funnel and the feeding pipe, the feeding pipe can repeatedly change the position of the concrete as the pouring frame moves, making the concrete pouring more uniform and reducing the situation where the aggregate is not completely crushed and gets stuck in the feeding funnel.

[0015] Optionally, a conveying pipe is also provided between the feeding hopper and the casting mixer. The two feeding hoppers are respectively set on the upper side of the two casting mixers. One end of the conveying pipe is connected to one of the feeding hoppers, and the other end of the conveying pipe is connected to the other feeding hopper. A spiral conveying rod is provided inside the conveying pipe, and the spiral conveying rod is used to drive the concrete to move along the conveying pipe.

[0016] By adopting the above technical solution, setting up a conveying pipe, and transporting the concrete to a relatively distant pouring mixer, the path for concrete to enter can be further increased, the concrete mixing time can be further improved, thereby further improving the degree of concrete mixing and the quality of concrete.

[0017] Optionally, the feeding funnel and the conveying pipe are detachably connected, and a baffle plate is provided on the feeding funnel corresponding to the feeding pipe, which can abut against the baffle plate when the feeding pipe moves.

[0018] By adopting the above technical solution and setting a baffle on the feed hopper, the movement of the feed pipe can be effectively limited, ensuring that the feed pipe can always discharge concrete within the range and reducing the occurrence of concrete flying out.

[0019] Optionally, a movable base is provided on the lower side of the aggregate mixer, the movable base is detachably connected to the aggregate mixer, and the bottom of the movable base is provided with lockable casters.

[0020] By adopting the above technical solution, a detachable movable base is set on the lower side of the aggregate mixer, and the bottom of the movable base is equipped with lockable casters, which can facilitate the movement and fixation of the aggregate mixer, and make it easy to adjust its position according to construction needs, thereby improving the flexibility and adaptability of the equipment.

[0021] Optionally, a connecting rod is provided between the movable seat and the casting frame, one end of the connecting rod being detachably connected to the movable seat and the other end being detachably connected to the casting frame.

[0022] By adopting the above technical solution, a detachable linkage rod is set up. When pouring is required, it can be removed and the moving seat locked. When the pouring area needs to be changed, the linkage rod is connected so that the moving seat can move together with the moving seat.

[0023] A method for integrated pouring of green concrete municipal pavement, using the aforementioned integrated pouring equipment, employs the following method: A. Set up pouring tracks and aggregate mixers on both sides of the pouring area, and set up pouring frames on the pouring tracks. After determining the area to be poured, lock the position of the aggregate mixer. B. Waste materials are used as aggregates and fed into an aggregate mixer, while raw materials are added and mixed to form concrete. C. The formed concrete is fed into the feed funnel through the feed pipe; D. The concrete in the feed hopper enters the casting mixer through the conveying pipe; E. The concrete mixer further mixes the concrete and pours it through the pouring pipe. After the pouring of this area is completed, the aggregate mixer is moved again to pour the concrete for the next area to be constructed.

[0024] By adopting the above technical solutions, the mixing time can be extended, thereby increasing the degree of mixing and further improving the quality of concrete.

[0025] In summary, this application has at least the following beneficial effects: This application solves the problem that in the prior art, when green concrete mixing uses waste materials to replace the original aggregates, uneven mixing can easily occur, affecting the quality of pouring. This application improves the mixing time by extending the conveying distance during the conveying process, thereby further improving the degree of mixing of concrete and the quality of pouring.

Circulation seat; Detailed Implementation The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] A green concrete municipal road surface integrated pouring equipment, such as Figure 1 and Figure 2 As shown, the system includes a pouring track 1 and an aggregate mixer 2. The pouring track 1 is laid on both sides of the construction area and along the construction area. A pouring frame 3 is slidably mounted on the pouring track 1 and can slide along the pouring track 1. The aggregate mixer 2 is used to mix raw materials and aggregates. In specific implementation, the movement of the pouring frame 3 on the pouring track 1 is achieved using motor-driven rollers. The aggregate mixer 2 needs to be fed with aggregates and other materials required for concrete formation, such as gels. The addition of aggregates can reduce the amount of gels and other materials used, thus enabling its use as green concrete.

[0031] like Figure 2 and Figure 3 As shown, a concrete mixing machine 31 is installed on the pouring frame 3. The concrete mixing machine 31 is used to mix concrete. A pouring pipe 32 is installed on the pouring frame 3, which is connected to the concrete mixing machine 31 and is used to discharge concrete. A feed pipe 21 is installed between the aggregate mixer 2 and the concrete mixing machine 31. The feed pipe 21 is used to feed the concrete mixed by the aggregate mixer 2 into the concrete mixing machine 31. A spiral mixing rod 211 is installed inside the feed pipe 21, which can drive the concrete to move towards the concrete mixing machine 31. In specific implementation, the concrete mixing machine 31 can continuously mix the concrete during the pouring process, so that the concrete is fully mixed, reducing various situations such as sedimentation and stratification during concrete pouring, and further improving the pouring quality. The spiral mixing rod 211 is equipped with a corresponding motor for driving.

[0032] like Figure 1 and Figure 2 As shown, one end of the feed pipe 21 is rotatably connected to the aggregate mixer 2. The end of the connecting rod 212 near the feed pipe 21 is ball-jointed with the feed pipe 21. The other end of the feed pipe 21 is also equipped with the connecting rod 212. The end of the connecting rod 212 away from the feed pipe 21 is connected to the pouring frame 3. When the pouring frame 3 moves, it can drive the feed pipe 21 to move. During the movement of the feed pipe 21, raw materials can always be discharged towards the pouring mixer 31. The aggregate mixer 2 has a rotating frame corresponding to the feed pipe 21. In practical implementation, pouring needs to be repeated in one area, therefore the pouring frame 3 needs to move. The feed pipe 21, through a rotatable connection, can move with the pouring frame 3, improving the stability of concrete input during pouring. The concrete flow method between the aggregate mixer 2 and the feed pipe 21 in this application involves setting a funnel on the feed pipe 21. The funnel can rotate with the feed pipe 21, and the aggregate mixer 2 directly discharges concrete towards the funnel through a pipe. like Figure 3As shown, a circulation seat 33 is provided on the pouring frame 3 corresponding to the pouring pipe 32. The pouring pipe 32 is deformable and fixed on the circulation seat 33. The circulation seat 33 is movably connected to the pouring frame 3 and moves cyclically along the length of the pouring frame 3. In specific implementation, the cyclic movement of the circulation seat 33 can be driven by a reciprocating screw, or by a motor, electric cylinder, or other means.

[0033] like Figure 1 and Figure 2 As shown, two casting mixers 31 are installed on the casting frame 3, with the casting mixers 31 located at both ends of the casting frame 3 along its length. Corresponding aggregate mixers 2 are also installed on both sides of the casting track 1. Feed pipes 21 are installed between the aggregate mixers 2 and the casting mixers 31. In practice, mixing and casting can be carried out simultaneously from both sides, allowing for a larger area to be cast in one go, further improving construction efficiency.

[0034] like Figure 1 and Figure 2 As shown, a feed hopper 311 is provided on the concrete pouring mixer 31. The interior of the feed hopper 311 is connected to the interior of the concrete pouring mixer 31. The feed hopper 311 is positioned corresponding to the nearby feed pipe 21, and the feed pipe 21 is always aligned with the feed hopper 311 when it moves. A conveying pipe 312 is also provided between the feed hopper 311 and the concrete pouring mixer 31. The two feed hoppers 311 are respectively located on the upper side of the two concrete pouring mixers 31. One end of the conveying pipe 312 is connected to one of the feed hoppers 311, and the other end of the conveying pipe 312 is connected to the other feed hopper 311. A screw conveyor 313 is provided inside the conveying pipe 312, and the screw conveyor 313 is also equipped with a corresponding motor for driving. The screw conveyor 313 is used to drive the concrete to move along the conveying pipe 312. In practice, the feed pipe 21 is rotated and its movement trajectory at the concrete outlet is semi-circular. The semi-circular movement trajectory allows the concrete to be delivered according to the cyclic landing point, thereby enabling the concrete to be delivered more evenly into the feed funnel 311 and reducing the situation where the concrete gets stuck in the feed funnel 311 due to uneven delivery.

[0035] like Figure 1 and Figure 2 As shown, the feeding funnel 311 and the conveying pipe 312 are detachably connected. A baffle plate 314 is provided on the feeding funnel 311 corresponding to the feeding pipe 21, which can abut against the baffle plate 314 when the feeding pipe 21 moves. In specific implementation, the baffle plate 314 can restrict the position of the feeding pipe 21, reduce the possibility of incorrect concrete delivery, and the detachable design facilitates the overall movement and adjustment.

[0036] like Figure 1 and Figure 2As shown, a movable base 22 is provided on the lower side of the aggregate mixer 2. The movable base 22 is detachably connected to the aggregate mixer 2, and a lockable caster wheel 221 is provided at the bottom of the movable base 22. A connecting rod 23 is provided between the movable base 22 and the casting frame 3. One end of the connecting rod 23 is detachably connected to the movable base 22, and the other end of the connecting rod 23 is detachably connected to the casting frame 3. In specific implementation, the lockable caster wheel 221 can be a commercially available caster wheel 221 that can be locked by a brake pad, while the connecting rod 23 can be detachably connected by various methods such as threaded connection or hook connection.

[0037] This embodiment also provides a method for integrated pouring of green concrete municipal pavement, using the aforementioned integrated pouring equipment and the following method: A. Set up pouring tracks 1 and aggregate mixers 2 on both sides of the pouring area, and set up pouring frames 3 on the pouring tracks 1. After determining the area to be poured, lock the position of the aggregate mixers 2. B. Waste materials are fed into aggregate mixer 2 as aggregates, and raw materials are fed into the mixer to make concrete. C. The formed concrete is fed into the feed hopper 311 through the feed pipe 21; D. The concrete in the feed hopper 311 enters the pouring mixer 31 through the conveying pipe 312; E. The concrete mixer 31 further mixes the concrete and pours it through the pouring pipe 32. After the pouring of this area is completed, the aggregate mixer 2 is moved again to pour the subsequent areas to be constructed.

[0038] Working principle: Extending the conveying distance during the conveying process increases the mixing time, further improving the degree of mixing of concrete and thus the quality of pouring.

[0039] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
