Description

Technical Field

[0001] The invention relates to the technical field of inverted arch construction, in particular to a material distribution device used for inverted arch casting. Background Art

[0002] The material distribution device for invert pouring is mainly used in tunnel construction. The invert is a reverse arch structure to improve the stress conditions of the upper supporting structure to solve the problem of insufficient foundation bearing capacity. Therefore, the pouring material quality diameter of the invert is related to the overall stability of the tunnel.

[0003] The traditional method of laying concrete is to lay concrete on the trestle using a concrete truck. Due to the large volume of concrete in the invert, the tunnel construction channel is often interrupted during the construction of the invert due to the concrete tank truck occupying the invert trestle. In addition, the invert formwork needs to be installed before pouring and removed after pouring, which affects the construction progress. The concrete truck laying concrete on the trestle may cause cross interference with the invert excavation below, posing a safety hazard.

[0004] The existing concrete distribution device transports concrete through a chute, and it is difficult to control the flow rate of concrete, and it is impossible to ensure that the concrete can flow out evenly and stably, which affects the continuity of construction. As a result, bubbles and voids may be generated during the concrete distribution, affecting the quality of the distribution. In addition, the existing concrete distribution device requires a lot of manual intervention and operation, and has a low degree of automation, which affects the efficiency of construction.

[0014] Furthermore, the mobile unit includes a No. 1 guide rail, a No. 1 wheel, a No. 1 shell, a No. 2 machine base and a No. 2 motor.

The No. 2 sliding block moves to the outlet with the flow rate of the concrete, and the No. 2 connecting rod makes the No. 2 inclined plate follow the No. 2 sliding block and push the No. 2 baffle plate to slide upward along the No. 2 through groove, so as to accurately control the cross-sectional area of ​​the outlet and accurately adjust the flow rate. By fixedly connecting the No. 2 sliding plate and the No. 2 sliding block, the No. 2 sliding plate can slide in the No. 4 chute, so that the No. 2 sliding plate moves with the No. 2 sliding block, so that the No. 3 chute is always not through the No. 2 chute, so as to avoid the concrete from flowing out of the No. 3 chute, thereby avoiding the waste of materials.

After the laying is completed, the arch template is lifted by the hydraulic cylinder, and the No. 2 wheel is driven to rotate by the No. 3 motor to move the arch template to the next workstation, thereby realizing the automation of construction.

[0020] Furthermore, the bottom surface of the No. 1 sliding block is triangular, and the No. 1 chute outlet gradually decreases along the outflow direction.

[0021] By setting the bottom surface of the No. 1 sliding block to a triangle, the No. 1 chute outlet gradually decreases along the outflow direction.

[0022] Furthermore, the bottom surface of the No. 2 sliding block is triangular, and the No. 2 chute outlet gradually decreases along the outflow direction.

[0023] By setting the bottom surface of the No. 2 sliding block to a triangle, the No. 2 chute outlet gradually decreases along the outflow direction. When the No. 2 sliding block moves toward the No. 2 chute outlet, the area is reduced, thereby reducing the flow rate of concrete. The auxiliary No. 2 baffle further fine-tunes the flow rate of concrete to ensure a uniform flow rate of concrete.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. Through the No. 1 sliding block, according to the force of the concrete flow on the No. 1 sliding block, the No. 1 sliding block is moved, thereby controlling the lifting and lowering of the No. 1 baffle, and then controlling the area of ​​the outlet to achieve the control of the concrete flow rate. The sliding block is tapered and cooperates with the gradually decreasing outlet to further fine-tune the flow rate of the concrete to ensure that the concrete can flow out evenly and stably, so that the invert can form a dense concrete layer, reduce the bubbles and voids generated during the concrete spreading, and improve the quality of the spreading.

[0026] 2. The No. 1 motor drives the slide bar to rotate, thereby realizing the angle adjustment of the No. 1 chute, so that the concrete can fall to every corner of the invert, reducing the gap caused by insufficient local distribution, thereby improving the density of the concrete and further improving the overall quality of the distribution.

[0027] 3. The No. 1 wheel is driven to rotate by the No. 2 motor, so that the No. 1 shell drives the No. 1 chute and the No. 2 chute to move, realizing the automation of material distribution, so that the material distribution mechanism can move from the head end of the invert to the end, thereby realizing the automated connection of material distribution and improving construction efficiency.

[0028] 4. Through the No. 1 and No. 2 feeding mechanisms, the material is laid from multiple points, which shortens the time of laying and improves the efficiency of construction. At the same time, multiple points of laying make the laying more uniform.

[0029] 5. Use a concrete pump to transport concrete to the chute for laying on the invert, so that the trestle is not occupied during the laying construction, allowing other construction vehicles to pass and improve construction efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] Through the No. 1 guide rail 441, the No. 1 wheel 442 can move on the trestle 1 along the No. 1 guide rail 441, and the No. 2 motor 445 is connected to the No. 1 wheel 442 through the output end, so that the No. 2 motor 445 can drive the No. 1 wheel 442 to rotate, so that the No. 1 wheel 442 is connected to drive the No. 1 shell 443 to move on the trestle 1, and the No. 1 shell 443 is fixedly connected to the fixed frame 43, thereby driving the fixed frame 43 to move on the trestle 1, so that the No. 1 chute 45 connected to the fixed frame 43 moves, and the automation of the material distribution of the No. 1 chute 45 is realized, and the No. 1 chute 45 is moved from the head end of the arch to the end, thereby realizing the automated connection and material distribution, and improving the construction efficiency.

[0052] like Figure 2 and Figure 6 As shown, the second material distributing mechanism 5 includes a second chute 51, a second sliding block 52, a second connecting rod 53, a second sliding plate 54, a second inclined plate 55 and a second baffle 56. The second chute 51 and the second sliding block 52 are slidably connected. The second chute 51 is provided with a third chute 511. The second connecting rod 53 and the third chute 511 are slidably connected. The second sliding block 52 and the second connecting rod 53 are fixedly connected. The second sliding plate 54 and the second sliding block 52 are fixedly connected. The second sliding plate 54 is slidably connected to the third chute 511, the fourth chute 512 is provided on the second chute 51, the second sliding plate 54 is slidably connected to the fourth chute 512, the second inclined plate 55 is fixedly connected to the second connecting rod 53, the second baffle plate 56 is slidably connected to the second inclined plate 55, the second chute 51 is provided with a second through groove 513, the second baffle plate 56 is slidably connected to the second through groove 513, and the second chute 51 is fixedly connected to the first shell 443.

[0053] The No. 2 chute 51 is fixedly connected to the No. 1 shell 443, so that the No. 2 chute 51 can realize automatic connection and distribution. The concrete is transported to the No. 2 chute 51 through the conveying pipe 42. The No. 2 sliding block 52 moves to the outlet with the flow of the concrete. The No. 2 inclined plate 55 follows the No. 2 sliding block 52 through the No. 2 connecting rod 53, and pushes the No. 2 baffle plate 56 to slide upward along the No. 2 through groove 513, so as to accurately control the cross-sectional area of ​​the outlet and accurately adjust the flow rate. The No. 2 sliding plate 54 is fixedly connected to the No. 2 sliding block 52, and the No. 2 sliding plate 54 can move along the No. 2 through groove 513. The No. 1 chute 512 slides, causing the No. 2 sliding plate 54 to move with the No. 2 sliding block 52, so that the No. 3 chute 511 is always not connected to the No. 2 chute 51, preventing concrete from flowing out of the No. 3 chute 511, thereby avoiding waste of materials. When the flow rate of concrete becomes smaller, the No. 2 baffle 56 slides downward and causes the height of the No. 1 baffle 475 to drop. The No. 2 inclined plate 55 can drive the No. 2 sliding block 52 to move to the initial position, thereby adjusting the flow rate of concrete. By distributing the concrete simultaneously with the No. 1 distributing mechanism 4, the distributing time is shortened, and distributing at multiple points makes the distributing more uniform.

[0055] The No. 2 wheel 32 is driven to rotate by the No. 3 motor 34, so that the No. 2 wheel 32 drives the No. 2 housing 33 to move on the No. 2 guide rail 31, so that the inverted arch formwork 36 is moved to a specified position, and the inverted arch formwork 36 is driven to move downward for installation by the hydraulic cylinder 35, and the inverted arch formwork 36 is laid by the No. 1 laying mechanism 4 and the No. 2 laying mechanism 5. After the laying is completed, the inverted arch formwork 36 is lifted by the hydraulic cylinder 35, and the No. 2 wheel 32 is driven to rotate by the No. 3 motor 34, so that the inverted arch formwork 36 is moved to the next workstation, thereby realizing the automation of construction.

[0056] like Fig.10 As shown, the bottom surface of the No. 1 sliding block 471 is triangular, and the outlet of the No. 1 chute 45 gradually decreases along the outflow direction.

[0057] By setting the No. 1 sliding block 471 to a semi-conical shape, the outlet of the No. 1 chute 45 gradually decreases. When the No. 1 sliding block 471 moves toward the outlet of the No. 1 chute 45, the area is reduced, thereby reducing the flow rate of concrete, and assisting the No. 1 baffle 475 to further fine-tune the flow rate of concrete to ensure a uniform flow rate of concrete.
