Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a self-compacting concrete pouring device for building foundation construction. Background Technology

[0002] Building foundation construction, as the basic engineering of the entire building construction, mainly refers to the process of injecting the mixed concrete into the foundation formwork, then vibrating it to make the concrete dense, and curing it to ensure that the concrete hardens, forming a stable base that can bear the load of the superstructure. Currently, some building construction uses self-compacting concrete, which can achieve the effect of dense forming by its own weight, without the need for vibration, thus improving the overall construction efficiency.

[0003] Currently, in some concrete pouring processes, concrete is usually injected directly into the formwork through a hose. The concrete is then discharged directly by a pump truck. There is a significant difference between the height of the concrete falling and the height of the foundation. During the pouring process, the aggregate and mortar are prone to separate, resulting in the accumulation of stones and insufficient mortar inside the foundation, which affects the pouring quality. In addition, if the pouring point is fixed, the concrete will accumulate in the same position, prolonging the time for the self-compacting concrete to spread and form itself, which can easily affect the efficiency of the overall pouring operation. Summary of the Invention

[0004] The purpose of this invention is to provide a self-compacting concrete pouring device for building foundation construction. Based on the same drive source, it can simultaneously achieve the effects of mixing, feeding, and expanding the pouring range, reducing the segregation of concrete during direct pouring. Furthermore, it can automatically expand the pouring range during the pouring process, reducing the possibility of large amounts of concrete accumulating in the same position. This solves the problems of some current pouring devices, where differences in pouring height easily affect the pouring quality, and fixed-position pouring easily affects the concrete spreading effect and even the overall work efficiency.

[0018] 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.

[0019] Please see Figures 1-7A self-compacting concrete pouring device for building foundation construction includes a storage tank 200 and a frame assembly 100 mounted on the storage tank 200. The frame assembly 100 includes a main frame 110. The storage tank 200 is fixed above the inner wall of the main frame 110. A receiving assembly 300 is provided on the top of the storage tank 200. The receiving assembly 300 includes a feed hopper 310 fixed on the top of the storage tank 200. A crossbar 320 is fixed on the inner wall of the feed hopper 310. Self-compacting concrete is injected into the feed hopper 310 through a pump pipe of a pump truck. The crossbar 320 supports the concrete and prevents it from falling directly downwards. The frame assembly 100 also includes a partition plate 120 bolted to the inner wall of the main frame 110. A drive assembly 400 is provided on the partition plate 120. The drive assembly 400 includes... The system includes a motor 410 mounted on one side surface of the partition 120, a conveying section 420 and a mixing section 430 mounted on the storage tank 200, and a connecting section 440 mounted on the partition 120. The conveying section 420 includes a power shaft 421 that movably penetrates the storage tank 200 and the partition 120. An auger blade 422 is fixed to the surface of the power shaft 421. One end of the power shaft 421 is fixed to the output shaft of the motor 410. When the motor 410 starts, it can drive the auger blade 422 to rotate through the power shaft 421, thereby conveying the concrete in the storage tank 200 outward. The mixing section 430 includes a support rod 431 that movably penetrates the storage tank 200 and the partition 120. A mixing rod 432 is fixed to the surface of the support rod 431. The surface of one side of the support rod 431 is fixed to the mixing section 430. A double-groove synchronous pulley 433 is fixed to the surface of the power shaft 421 and the other side support rod 431. Single-groove synchronous pulleys 423 are also fixed to the surfaces of the single-groove synchronous pulleys 423 and the double-groove synchronous pulleys 433, as well as between the two single-groove synchronous pulleys 423, via synchronous belt drives. When the power shaft 421 rotates, one side of the single-groove synchronous pulley 423 rotates with the power shaft 421 and drives the double-groove synchronous pulley 433 to rotate via the synchronous belt. Simultaneously, through the connection between the double-groove synchronous pulley 433 and the synchronous belt, the two support rods 431 can rotate simultaneously. Furthermore, the stirring rod 432 rotates with the support rod 431 to mix the concrete in the storage tank 200, preventing segregation of the concrete when it is poured into the storage tank 200 from above. The stirring rod 432 is located in the storage tank 200. Inside the storage tank 200, both the single-groove synchronous pulley 423 and the double-groove synchronous pulley 433 are installed on the surface of the storage tank 200. This isolates the concrete from the single-groove synchronous pulley 423 and the double-groove synchronous pulley 433, reducing the impact on the normal operation of the synchronous belt, the single-groove synchronous pulley 423, and the double-groove synchronous pulley 433. A compression ring 434 is fixed to the surface of the support rod 431, and the surface of the compression ring 434 abuts against the surface of the partition plate 120, which can strengthen the stability of the support rod 431. The connecting part 440 includes an anti-detachment plate 441 fixed to the surface of the partition plate 120. A vertical rod 442 rotatably passes through the anti-detachment plate 441. A bevel gear 443 is fixed to the top of the vertical rod 442. A conical gear ring 444 is fixed to the surface of the drive shaft 421, and the bevel gear 443 meshes with the conical gear ring 444.When the motor 410 starts and drives the power shaft 421 to rotate, the bevel gear 444 rotates accordingly, and the bevel gear 443 drives the vertical rod 442 to rotate. A moving part 450 is provided below the connecting part 440. The moving part 450 includes a turntable 451 fixed to the bottom of the vertical rod 442. A protrusion 452 is fixed to the bottom of the turntable 451, and a hollow frame 453 is fitted onto the surface of the protrusion 452. A guide rod 460 is fixed to the inner wall of the main frame 110. The guide rod 460 slides through the hollow frame 453, guiding the movement of the hollow frame 453. Accordingly, the protrusion 452... As the turntable 451 rotates, the hollow frame 453 is subjected to force and, guided by the guide rod 460, can reciprocate laterally. A ball bearing 454 is embedded in the bottom of the hollow frame 453. A base plate 130 is fixed to the inner wall of the main frame 110, and a partition plate 120 is engaged with the base plate 130. The base plate 130 supports the partition plate 120, thus reinforcing the stability of the main frame 110 and increasing the stability of the partition plate 120 after installation. The ball bearing 454 contacts the top of the base plate 130. When the hollow frame 453 moves, the ball bearing 454 cooperates with the base plate 130, increasing the smoothness of the hollow frame 453's movement and reducing air pockets. The hollow frame 453 experiences jamming during movement. A feeding assembly 500 is installed on the storage tank 200, including a feeding pipe 510 bolted to the surface of the storage tank 200. The outer edge of the auger blade 422 is clearance-fitted with the inner wall of the feeding pipe 510. Rotation of the auger blade 422 allows for stable conveying of concrete within the feeding pipe 510. A flexible hose 520 is connected to the end of the feeding pipe 510 furthest from the storage tank 200. A bracket 530 is fixed to the surface of the flexible hose 520, and an L-shaped rod 540 is fixed to the surface of the bracket 530. The end of the L-shaped rod 540 furthest from the bracket 530 is fixed to the hollow frame 453. The hollow frame 453... 3. During lateral reciprocating movement, the support 530 moves laterally and reciprocally via the L-shaped rod 540. The position of the end of the hose 520 furthest from the feeding pipe 510 is adjusted, expanding the pouring area and improving the overall efficiency of foundation pouring. A positioning ring 560 is fixed to the surface of the hose 520, and a limit ring 550 is fixed to the end of the feeding pipe 510 furthest from the storage tank 200. The limit ring 550 is rotatably positioned inside the positioning ring 560. The connection between the limit ring 550 and the positioning ring 560 stabilizes the connection between the hose 520 and the feeding pipe 510, preventing the hose 520 from falling and affecting the large-scale pouring operation.

[0020] More preferably, a sealing ring can be added at the connection between the feeding pipe 510 and the storage tank 200 to improve the sealing effect after the feeding assembly 500 is installed, and to prevent the self-compacting concrete from overflowing from the connection between the storage tank 200 and the feeding pipe 510.

[0021] A baffle 140 is fixed to the inner wall of the main frame 110. The top of the baffle 140 is fixed to the bottom of the storage tank 200. A groove is provided on the surface of the baffle 140. The surface of the L-shaped rod 540 contacts the inner wall of the groove. The groove on the surface of the baffle 140 can support the L-shaped rod 540. A rectangular frame 570 is fixed to both sides of the baffle 140. A bellows cover 580 is fixed to the inner wall of the rectangular frame 570. The L-shaped rod 540 is fixed through the bellows cover 580. The bellows cover 580 can cover the rectangular frame 570 and the groove, reducing the amount of concrete entering the groove and below the storage tank 200, and ensuring that the L-shaped rod 540 can move laterally normally in the future.

[0022] Working principle: The pump pipe of the pump truck is aligned with the top of the feed hopper 310, and then the self-compacting concrete is injected into the receiving group 300. At this time, the crossbar 320 can support the concrete and reduce its downward impact. The operator starts the motor 410, and the power shaft 421 rotates accordingly, driving the auger blades 422 and the single-groove synchronous pulley 423 to rotate. The auger blades 422 rotate and transport the concrete. The single-groove synchronous pulley 423 cooperates with the synchronous belt to drive the double-groove synchronous pulley 433 to rotate. The double-groove synchronous pulley 433 cooperates with the synchronous belt, and the two side support rods 431 simultaneously drive the mixing rod 432 to rotate, thereby mixing the concrete in the storage tank 200 to prevent the concrete from segregating, so as to prepare for subsequent concrete transportation and use for pouring the foundation. When the support rod 431 rotates, the material conveying section 420 and the mixing section 430 start simultaneously. At the same time, the bevel gear 443 and the bevel gear ring 444 cooperate to drive the vertical rod 442 to rotate. The turntable 451 rotates accordingly and drives the protrusion 452 to rotate. The hollow frame 453 is subjected to force when the protrusion 452 moves. At this time, under the guidance of the guide rod 460, the hollow frame 453 drives the L-shaped rod 540 to move back and forth laterally. The movement of the L-shaped rod 540 can adjust the position of one end of the hose 520 through the bracket 530, thereby expanding the pouring range and improving the overall work efficiency. When the hose 520 is pulled, the positioning ring 560 can rotate inside the limiting ring 550 to avoid folding and affecting the pouring operation.
