[0002] A shield tunnel boring machine, abbreviated as a shield machine, is a special engineering machinery for tunnel excavation. It has been widely used in tunnel projects such as subways, railways, highways, municipal engineering, and hydropower. The shield machine is indispensable for the pipe segment. During the production process of the shield pipe segment, it needs to be formed through the corresponding mold. Usually, the pipe segment is formed and demolded through the cooperation of the hand hole box.

[0003] In the existing technology, the demoulding angle of the hand hole box is not enough and cannot be demoulded normally. The hand hole box is divided into two parts. The part that affects the demoulding is made into a sliding rubber block. When the pipe segment is demoulded, the rubber block falls off along with the pipe segment, making it easy to take out and recycle after demoulding.

[0004] In the existing technical solution, rubber blocks are used to assist in demoulding the pipe segments, but the installation of the rubber sheets is generally fixed with auxiliary parts such as bolts, so the disassembly and assembly method is less efficient, affecting production efficiency.

An extension plate 406 is fixedly installed at the position of the positioning hole 407 at the bottom of the block 402. A sliding structure is formed between the slide groove 401 and the block 402. The structure of the block 402 is a T-shaped structure. The transverse reinforcing ribs 404 penetrate into the interior of the connecting plate 403. The transverse reinforcing ribs 404 and the vertical reinforcing ribs 405 are perpendicular to each other. A sliding structure is formed between the extension plate 406 and the slide groove 401. The outer dimensions of the extension plate 406 are consistent with the outer dimensions of the positioning hole 407.

[0028] By adopting the above technical solution, the block 402 fixed by the connecting plate 403 inside the rubber slider body 2 is convenient for sliding connection along the slide groove 401 of the fixed hand hole box 1, so as to quickly perform disassembly and assembly, and cooperate with the horizontal reinforcement ribs 404 and the vertical reinforcement ribs 405 to improve the durability and life of the rubber slider body 2. At the same time, the extension plate 406 at the bottom end of the block 402 is inserted into the positioning hole 407 to improve the stability of the connection between the fixed hand hole box 1 and the rubber slider body 2 to avoid loosening.

[0029] Specifically, such as Figure 1 、 Figure 2 and Figure 5 As shown, a stabilizing mechanism 5 is provided on one side of the rubber slider body 2, and the stabilizing mechanism 5 includes a connecting plate 501, which is embedded in the front end of the rubber slider body 2, and the end of the connecting plate 501 that penetrates the rubber slider body 2 is fixedly installed with a penetration block 502, and the end of the penetration block 502 that penetrates the rubber slider body 2 is embedded with a damping spring 503, and the end of the damping spring 503 away from the penetration block 502 is fixedly installed with a roller 504, and the stabilizing mechanism 5 also includes a limiting hole 505, which is opened on one side of the outer wall slide groove 401 of the fixed hand hole box 1, and the inner wall of the limiting hole 505 is embedded with a contact plate 506, and the roller 504 forms an elastic structure between the damping spring 503 and the penetration block 502, and a sliding structure is formed between the roller 504 and the fixed hand hole box 1.

[0030] By adopting the above technical solution, the connecting plate 501 and the penetration block 502 are fixed to the inner wall of the rubber slider body 2, and the roller 504 is elastically pushed by the damping spring 503. When the fixed hand hole box 1 and the rubber slider body 2 are assembled, the roller 504 slides along the fixed hand hole box 1 until it penetrates the limiting hole 505 and elastically abuts against the abutment plate 506. The roller 504 penetrates the limiting hole 505 normally, and is easy to disengage during disassembly and assembly while being engaged. Through the elasticity of the damping spring 503 and the limitation of the extension plate 406, a relative force is formed to improve the stability of the fixed hand hole box 1 and the rubber slider body 2 during assembly.

[0031] Working principle: The connecting plate 403 fixed inside the rubber slider body 2 is slidably connected to the fixed hand hole box 1 through the block 402 and the slide groove 401, which facilitates the quick disassembly and assembly of the fixed hand hole box 1 and the rubber slider body 2. The hardness of the rubber slider body 2 is improved by the horizontal reinforcement ribs 404 and the vertical reinforcement ribs 405. At the same time, the extension plate 406 is inserted into the positioning hole 407 to improve the connection stability. The connecting plate 501 and the penetration block 502 are fixed to the inner wall of the rubber slider body 2. The damping spring 503 elastically pushes the roller 504 to slide along the fixed hand hole box 1 until it penetrates the limiting hole 505 and contacts the contact plate 506 for limitation, and has a certain shock absorption effect. At the same time, it can cooperate with the extension plate 406 and the positioning hole 407 to form a relative force, which can improve the stability of the fixed hand hole box 1 and the rubber slider body 2. The positioning hole 407 engages half of the roller 504 for convenient disassembly and assembly.
