Description

Technical Field

[0001] This utility model relates to the field of walkway guardrail technology, and in particular to an assembled walkway guardrail for shield tunneling construction. Background Technology

[0002] A tunnel boring machine (TBM) is a construction machine used to excavate underground tunnels. TBM construction enables the rapid excavation of underground tunnels. During TBM construction, workers need to walk on the bottom of the tunnel lining segments to excavate slag. If workers walk on this area, they are prone to stepping on the slag and getting injured. Therefore, walkway railings are usually installed around the TBM construction site. However, existing walkway railings typically require multiple screws during assembly, which necessitates frequent screw tightening by workers. This results in high labor intensity, low efficiency, and makes it difficult to achieve rapid assembly of walkway railings. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the existing technology, this utility model provides an assembled walkway guardrail for shield tunneling construction, which effectively solves the problem that the existing walkway guardrails require personnel to frequently tighten screws during assembly, resulting in high labor intensity, low efficiency, and difficulty in achieving rapid assembly of the walkway guardrails.

[0004] The technical solution includes a column with three mounting holes, an internal mounting post with three round holes and three square holes, a movable rod fixedly connected to one end of the mounting post, a spring sleeved on the movable rod, a fixed plate fixedly connected inside the column, the movable rod slidably connected to the fixed plate, three support rods on the column, a connecting post fixedly connected to one end of each support rod, and a round cap fixedly connected to one end of each connecting post.

[0005] Preferably, a fluorescent lamp is installed on the column, and a base is fixedly connected to the bottom of the column.

[0006] Preferably, a threaded column is fixedly connected to the support rod, and the column has three threaded holes.

[0007] Preferably, a fixing post is fixedly connected to one end of the mounting post, and a pressing cap is fixedly connected to one end of the fixing post.

[0008] Preferably, a plastic pad is provided on the pressing cap, and a plastic sleeve is fixedly connected to the support rod.

[0009] Preferably, the threaded column is threaded onto the column, and the movable rod is disposed inside the column.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This modular walkway railing for shield tunneling construction utilizes square holes, round holes, connecting posts, round caps, and springs. When assembling multiple posts, pressing the plastic pad on one post causes the pressing cap, fixing post, and mounting post to move downwards, aligning the center of the round hole with the center of the mounting hole. Then, the round cap on another post is passed through the mounting hole and the round hole, and pressing the plastic pad stops. The spring returns to its original position, pushing the mounting post upwards, causing the square hole to engage with the connecting post. Since the distance between the two faces of the square hole is equal to the diameter of the connecting post but smaller than the diameter of the round cap, the support rod is effectively limited, thus completing the assembly of multiple posts. Disassembling the posts simply requires repeating the above steps in reverse. This walkway railing requires only pressing the plastic pad and passing the round cap through the mounting hole and the round hole to complete the assembly, resulting in fewer steps, lower labor intensity, and faster assembly.

[0012] 2. This modular walkway railing for shield tunneling construction uses support rods, threaded posts, threaded holes, and plastic sleeves. When a support rod needs to be replaced, first disassemble the two posts, then hold the plastic sleeve and rotate the support rod. The support rod drives the threaded post to rotate on the threaded hole, causing the support rod to move and be removed from the post. The support rod can then be replaced. Installation is done by repeating the disassembly and reassembly process. When one support rod is damaged, it is not necessary to replace the post and multiple support rods as a whole, reducing operating costs. Attached Figure Description

[0018] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0019] Depend on Figures 1 to 4As shown, this utility model includes a column 1 with three mounting holes 2, a mounting post 8 inside the column 1, and a fluorescent lamp 3 on the column 1. Because of the fluorescent lamp 3, the fluorescent lamp 3 can emit light to attract people's attention and prevent people from tripping due to inattention, thus improving safety. A base 4 is fixedly connected to the bottom of the column 1.

[0020] The mounting post 8 has three round holes 15 and three square holes 16. A moving rod 9 is fixedly connected to one end of the mounting post 8, and a spring 10 is sleeved on the moving rod 9. A fixing post 12 is fixedly connected to one end of the mounting post 8. Because the fixing post 12 is square in shape, it can prevent the round holes 15 from shifting due to the rotation of the mounting post 8, thus improving stability. A pressing cap 13 is fixedly connected to one end of the fixing post 12.

[0021] The column 1 is fixedly connected to a fixed plate 11, and the moving rod 9 is slidably connected to the fixed plate 11. The column 1 is provided with three support rods 5, and threaded rods 6 are fixedly connected to the support rods 5. The column 1 is provided with three threaded holes 7.

[0022] One end of the support rod 5 is fixedly connected to a connecting column 17, and the other end of the connecting column 17 is fixedly connected to a round cap 18. A plastic pad 14 is provided on the pressing cap 13. Because the plastic pad 14 is made of a soft material, it is more comfortable for personnel to press the plastic pad 14, making it easier for personnel to operate. A plastic sleeve 19 is fixedly connected to the support rod 5. Because the plastic sleeve 19 is provided, the plastic sleeve 19 has a large friction and has an anti-slip function, making it easier for personnel to rotate the support rod 5 and improving the ease of operation. The threaded column 6 is threadedly connected to the column 1, and the moving rod 9 is located inside the column 1.

[0023] The working principle of this utility model is as follows:

[0024] When multiple columns 1 need to be assembled, press the plastic pad 14 on one of the columns 1 to move the pressing cap 13, the fixing column 12 and the mounting column 8 downward, so that the center of the round hole 15 and the center of the mounting hole 2 are on the same horizontal line. At this time, pass the round cap 18 on the other column 1 through the mounting hole 2 and the round hole 15 and stop pressing the plastic pad 14. The spring 10 will return to its original position and push the mounting column 8 upward, so that the square hole 16 is locked on the connecting column 17. Since the distance between the two faces of the square hole 16 is equal to the diameter of the connecting column 17 but smaller than the diameter of the round cap 18, the support rod 5 can be limited, thus completing the assembly of multiple columns 1. When disassembling the columns 1, it is only necessary to repeat the above operation in reverse.

[0025] When the support rod 5 needs to be replaced, first remove the two columns 1, and hold the plastic sleeve 19 to rotate the support rod 5. The support rod 5 drives the threaded column 6 to rotate on the threaded hole 7, which will cause the support rod 5 to move, thereby removing the support rod 5 from the column 1 and replacing the support rod 5. The disassembly operation is repeated in reverse during installation.
