Description

Technical Field

[0001] This utility model relates to the field of tunnel construction technology, and in particular to a high-efficiency tunnel secondary lining concrete pouring balanced distribution device. Background Technology

[0002] When pouring concrete for tunnels, concrete pumps are usually used to directly distribute the concrete through the pouring window. However, in order to improve pouring efficiency and make reasonable use of the tunnel's height, a tunnel secondary lining concrete pouring balance distribution device is set up to quickly complete the lateral distribution of concrete, while preventing concrete slurry separation and ensuring the quality of the concrete.

[0003] The existing high-efficiency tunnel secondary lining concrete pouring balanced distribution device has the following drawbacks:

[0004] Chinese Patent Publication No. CN208330405U, published on January 4, 2019, discloses a balanced material distribution and diversion device for tunnel secondary lining concrete pouring. The device includes a silo with four horizontal diversion pipes evenly distributed on it. Each horizontal diversion pipe's outlet is connected to a longitudinal diverter. This device achieves multi-point balanced material distribution and gravity-flow into the silo during tunnel secondary lining concrete pouring, overcoming the problems of trolley misalignment and poor concrete uniformity caused by single-point material distribution. This creates conditions for rapid tunnel secondary lining construction. Compared with existing technologies, it has advantages such as convenient construction, controllable quality, low labor intensity, and high efficiency. It is suitable for railway, highway, and subway tunnel construction and has significant application value.

[0005] However, the devices described in the aforementioned published documents mainly focus on how to solve the problems of labor-intensive and time-consuming processes, without considering the inconvenience of assembling existing devices. When assembling the device, flanges and bolts are usually used to connect and fix multiple sections of main pipe. However, since bolts require matching tools for installation and the installation process is cumbersome and time-consuming, it affects the convenience of the device.

[0006] In view of this, it is necessary to develop a high-efficiency tunnel secondary lining concrete pouring balance distribution device, so as to improve the convenience of using the high-efficiency tunnel secondary lining concrete pouring balance distribution device. Utility Model Content

Distribution pipes are provided on both sides of the main pipe, and an extension structure is provided on the outer side of the distribution pipe. The distribution pipe and the main pipe are both provided with an isolation structure. The connecting structure includes a fixed seat, a connecting rod, a pressure plate and a cam block. The fixed seat is fixed to the top of both sides of the main pipe, and a connecting rod is hinged to one side of the fixed seat.

[0011] The high-efficiency tunnel secondary lining concrete pouring balanced distribution device using this technical solution receives the poured concrete through the feed hopper and guides it into the interior of the main pipeline. The concrete is then distributed through the distribution pipe to facilitate simultaneous introduction into multiple locations. The connection between the distribution pipe and the main pipeline is controlled by an isolation structure, the length of the distribution pipe is extended by an extension structure, and the connection structure facilitates quick and easy connection and fixation of the feed hopper to the main pipeline or multiple sets of main pipelines.

[0012] Preferably, a cam block is installed at the top of the connecting rod, and the pressure plate is fixed to the bottom of the feed hopper. By aligning the feed hopper with the main pipe, the connecting rod is then pulled to move the cam block above the pressure plate. By pulling the cam block, the cam block flips downward and pushes the connecting rod downward, so that the feed hoppers are tightly connected.

[0013] Preferably, the cam block and the connecting rod form a rotating structure, and the connecting rod passes through the pressure plate and is connected to the cam block.

[0014] Preferably, the isolation structure includes a partition, a mounting groove, and a handle. The mounting groove is fixed inside the distribution pipe, the partition is inserted inside the mounting groove, and the handle is fixed to the top of the partition. The partition blocks the flow of concrete inside the distribution pipe, and pulling the handle away from the inside of the distribution pipe allows the concrete to flow inside the distribution pipe.

[0032] Example 1

[0033] Please see Figure 1-5 This utility model provides a high-efficiency tunnel secondary lining concrete pouring balanced distribution device, including a feed hopper 1, a main pipe 3, and a distribution pipe 5. The bottom end of the feed hopper 1 is provided with a connecting structure 2, and the bottom end of the connecting structure 2 is provided with the main pipe 3. The two sides of the main pipe 3 are provided with distribution pipes 5, and the outer side of the distribution pipes 5 is provided with an extension structure 6. The distribution pipes 5 and the main pipe 3 are both provided with an isolation structure 4. The connecting structure 2 includes a fixed seat 201, a connecting rod 202, a pressure plate 203, and a cam block 204. The fixed seat 201 is fixed to the top of both sides of the main pipe 3. The connecting rod 202 is hinged to one side of the fixed seat 201. The cam block 204 is installed at the top of the connecting rod 202. The pressure plate 203 is fixed to the bottom end of the feed hopper 1. The cam block 204 and the connecting rod 202 form a rotating structure. The connecting rod 202 passes through the pressure plate 203 and is connected to the cam block 204.

[0034] The working principle of the high-efficiency tunnel secondary lining concrete pouring balanced distribution device based on Embodiment 1 is as follows: the concrete is received by the feed hopper 1 and introduced into the interior of the main pipe 3. The concrete is then distributed through the distribution pipe 5 to facilitate simultaneous introduction into multiple locations. The connection between the distribution pipe 5 and the main pipe 3 is controlled by the isolation structure 4. The length of the distribution pipe 5 is extended by the extension structure 6. The feed hopper 1 is quickly connected and fixed to the main pipe 3 or multiple main pipes 3 by the connecting structure 2. The feed hopper 1 is placed on top of the main pipe 3 to align it with the main pipe 3. Then, the connecting rod 202 is moved to move the cam block 204 above the pressure plate 203. By pulling the cam block 204, the cam block 204 is flipped downwards. At the same time, the cam block 204 pushes the connecting rod 202 downwards, so that the feed hopper 1 is tightly connected to the main pipe 3, and the device is assembled and fixed.

[0035] Example 2

[0036] This embodiment includes: the isolation structure 4 includes a partition 401, a mounting groove 402 and a handle 403. The mounting groove 402 is fixed inside the distribution pipe 5. The partition 401 is inserted inside the mounting groove 402. The handle 403 is fixed at the top of the partition 401. The partition 401 and the mounting groove 402 form a sliding structure. The width of the partition 401 is greater than the inner diameter of the distribution pipe 5.

[0037] In this embodiment, the partition 401 is placed horizontally inside the distribution pipe 5 to block the flow of concrete inside the distribution pipe 5. Pulling the handle 403 upward causes the partition 401 to leave the inside of the distribution pipe 5, allowing the concrete to flow inside the distribution pipe 5. The installation groove 402 guides the movement of the partition 401, so that the partition 401 accurately seals the distribution pipe 5.

[0039] This embodiment includes: the extension structure 6 includes a lead screw 601, an extension cylinder 602 and a moving groove 603. The extension cylinder 602 is sleeved on the outside of the distribution pipe 5. Lead screws 601 are inserted on both sides of the extension cylinder 602. A moving groove 603 is provided on one side of the lead screw 601. The moving groove 603 and the extension cylinder 602 form a sliding structure. The lead screw 601 passes through the extension cylinder 602 and is connected to the moving groove 603.

[0040] In this embodiment, by pulling the extension cylinder 602, the extension cylinder 602 slides on the outside of the distribution pipe 5, adjusting the position of the concrete pouring in the distribution pipe 5. By rotating the screw 601, the screw 601 moves closer to the moving groove 603, increasing the resistance of the extension cylinder 602 moving on the outside of the moving groove 603, and fixing the position of the screw 601.
