Description

Technical Field

[0001] This utility model relates to the field of construction equipment technology, and in particular to a self-compacting concrete pouring device with dynamic pressure compensation. Background Technology

[0002] A self-compacting concrete pouring device is a specialized piece of equipment for pouring self-compacting concrete. Its purpose is to efficiently, uniformly, and with high quality pour self-compacting concrete into a designated structural space to meet the requirements of engineering construction.

[0003] A search revealed Chinese Patent Publication No. CN219634140U, which discloses a self-compacting concrete pouring device, comprising a support plate, a mixing device, an air bubble elimination device, and a discharge pipe. The mixing device is fixedly installed above the support plate, and the air bubble elimination device is fixedly installed below the support plate. The discharge end of the mixing device is connected to the inlet end of the air bubble elimination device, and the discharge end of the air bubble elimination device is connected to the discharge pipe. The mixing device includes a mixing tank, a second motor, a mixing roller, and mixing blades. The air bubble elimination device includes a fixed box, a first motor, and a rotating roller. The discharge pipe includes a connecting pipe and a side pipe. After the concrete is mixed in the mixing device, it enters the air bubble elimination device to eliminate internal air bubbles, and finally is discharged through the discharge pipe. This invention solves the problem that in existing pouring devices, when pouring concrete, air bubbles adhere to the surrounding structure due to the interaction between the concrete and the structure, and the air bubbles contained in the concrete affect the strength of the concrete and the structure after solidification.

[0004] In the aforementioned application, the mixed self-compacting concrete is first fed into the storage hopper of the grouting device. The mixing device inside the storage hopper operates continuously. However, since the nozzle is not cleaned, the residual concrete can easily cause partial or complete blockage of the grouting pipe after hardening. Utility Model Content

[0015] As a further description of the above technical solution: A first motor is fixed inside the injection body, and a rotating bevel gear is connected to the output end of the first motor. When the first motor drives the rotating bevel gear to rotate, the rotating bevel gear meshes with the bevel gear roller through the tooth end, and transmits power to the bevel gear roller, so that the bevel gear roller rotates.

[0035] Reference Figure 4 and Figure 5 The flipping assembly 9 includes a second support frame 901. A miniature electric push rod 902 is fixedly connected inside the second support frame 901. A support rod 903 is connected to the output end of the miniature electric push rod 902. A support plate 904 is rotatably connected to the outer wall of the support rod 903. The outer wall of the support plate 904 is rotatably connected to the inside of the second support frame 901. A cleaning nozzle 10 is fixedly connected to the lower surface of the support plate 904. A water pipe 11 is fixedly connected inside the cleaning nozzle 10. A water tank 12 is fixedly connected to the outer wall of the water pipe 11. A water inlet 13 is fixedly connected to the outer wall of the water tank 12.

[0036] Specifically, the second support frame 901 supports the miniature electric push rod 902, which drives the support rod 903 to rotate. The support rod 903 drives the support plate 904 to rotate. The second support frame 901 supports the support plate 904 to rotate, and the support plate 904 drives the cleaning nozzle 10 to flip. The water inlet 13 receives tap water, the water tank 12 stores tap water, the water pipe 11 transports tap water, and the cleaning nozzle 10 sprays tap water. This achieves the effect of flipping the cleaning nozzle 10, effectively preventing concrete from hardening and solidifying inside the grouting pipe and reducing the risk of grouting pipe blockage.

[0037] Reference Figures 3-5 The injection body 1 is internally fixedly connected to a first motor 14. The output end of the first motor 14 is connected to a rotating bevel gear 15. The tooth end of the rotating bevel gear 15 is meshed with a bevel roller 16. The injection body 1 is internally provided with a swing assembly 17. The swing assembly 17 includes a second motor 1701.

The inside of the third support frame 18 is fixedly connected to the outer wall of the first motor 14. The outer wall of the bevel roller 16 is rotatably connected to the inside of the V-shaped frame 1704.

[0038] Specifically, the first motor 14 drives the rotating bevel gear 15 to rotate, and the rotating bevel gear 15 drives the bevel roller 16 to rotate.

The swinging device allows the grouting pipe to swing within a certain angle range and expand the grouting range.

[0039] Working principle: When the self-compacting concrete pouring device is needed, the micro electric push rod 902 drives the support rod 903 to rotate, thereby rotating the support plate 904 and driving the cleaning nozzle 10 to rotate, fixing the second support frame 901, and then fixing the water pipe 11 inside the water tank 12, thereby fixing the water tank 12 to the outer wall of the second support frame 901, and then fixing the water inlet 13, thereby achieving the effect of the cleaning nozzle 10 flipping.

[0040] The first motor 14 drives the rotating bevel gear 15 to rotate, thereby causing the bevel roller 16 to rotate. This further drives the second motor 1701 to drive the transmission gear 1702 to rotate, causing the gear ring 1703 to rotate inside the third support frame 18. This, in turn, causes the third support frame 18 to be fixed to the outer wall of the first motor 14, which in turn causes the bevel roller 16 to rotate inside the V-shaped frame 1704. This, in turn, causes the V-shaped frame 1704 to be fixed, thereby achieving the effect of the bevel roller 16 rotating and oscillating.

[0041] This not only allows for the cleaning of the inside of the grouting pipe by flipping the nozzle and using high-pressure water or other cleaning media, thus promptly removing residual self-compacting concrete and effectively preventing the concrete from hardening and solidifying inside the grouting pipe, reducing the risk of grouting pipe blockage, but also enables the grouting device to move flexibly within the construction site. The swinging device allows the grouting pipe to swing within a certain angle range, expanding the grouting range.
