Description

[0002] The distribution device for inverted arch pouring is mainly used for tunnel construction. The inverted arch is a reverse arch structure for improving the stress condition of the upper support structure to solve the problem of insufficient foundation bearing capacity. Therefore, the pouring distribution quality of the inverted arch is related to the overall stability of the tunnel.

[0003] In the traditional distribution method, the concrete truck is used for distribution on the trestle. Due to the large amount of inverted arch concrete, the tunnel construction channel is interrupted due to the occupation of the inverted arch trestle by the concrete tank truck during inverted arch construction. In addition, the inverted arch formwork needs to be installed before pouring and removed after pouring, which affects the construction progress. The concrete truck may interfere with the excavation of the inverted arch below, which poses a safety hazard.

[0004] The existing distribution device uses a chute to convey concrete, which is difficult to control the flow rate of the concrete and cannot ensure that the concrete flows out uniformly and stably, affecting the continuity of the construction, which may produce bubbles and cavities during concrete distribution, affecting the quality of the distribution.

[0056] like Figure 10 As shown, the bottom surface of the first sliding block 471 is triangular, and the outlet of the first chute 45 gradually decreases along the outflow direction.

[0057] By setting the first sliding block 471 into a semi-conical shape, the outlet of the first chute 45 gradually decreases. When the first sliding block 471 moves toward the outlet of the first chute 45, the area decreases, thereby reducing the flow rate of concrete. This assists the first baffle 475 in further fine-tuning the flow rate of concrete and ensuring that the concrete flow rate is uniform.

[0058] As Figure 11 shown, the bottom surface of the second sliding block 52 is triangular, and the outlet of the second chute 51 gradually decreases in the flow direction.

[0059] By setting the second sliding block 52 to be conical and gradually reducing the outlet of the second chute 51, the area is reduced when the second sliding block 52 moves to the outlet of the second chute 51, thereby reducing the flow of concrete, assisting the second baffle 56 to further fine-tune the flow rate of the concrete, and ensuring uniform concrete flow rate.

[0060] Working principle: move the trestle 1 to the construction position and erect it through the walking mechanism 2, drive the second wheel 32 through the third motor 34, drive the second shell 33 to move, erect the inverted arch formwork 36 to the inverted arch through the hydraulic cylinder 35, and make the concrete be transported to the first chute 45 and the second chute 51 through the concrete pump truck 41 and the conveying pipe 42, drive the first connecting rod 472 through the first sliding block 471 to make the first inclined plate 474 push the first baffle 475 to move upward, reduce the area of the outlet, thereby controlling the flow, set the bottom surface of the first sliding block 471 to be triangular, and gradually reduce the outlet of the first chute 45 in the flow direction, assist the first baffle 475 to further fine-tune the flow rate of the concrete, drive the second connecting rod 53 through the second sliding block 52 to make the second inclined plate 55 push the second baffle 56 to move upward, reduce the area of the outlet, thereby controlling the flow, set the bottom surface of the second sliding block 52 to be triangular, and gradually reduce the outlet of the second chute 51 in the flow direction, assist the second baffle 56 to further fine-tune the flow rate of the concrete, drive the first wheel 442 through the second motor 445 to make the first shell 443 move on the first guide rail 441, move the first chute 45 and the second chute 51, and drive the sliding rod 462 to rotate through the first motor 464, thereby adjusting the angle of the first chute 45.
