[0002] ‌TBM grippers‌ are a key component in the propulsion system of TBM (full-face rock tunnel boring machine). The main function of the grippers is to tighten the surrounding rock during the excavation process, providing the force required for the cutterhead to move forward and the torque required for the cutterhead to rotate.‌

[0037] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0039] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0040] When TBM encounters soft rock and broken zones during excavation, low surrounding rock strength or cavity collapse occurs. The surrounding rock cannot withstand the force transmitted by the support shoe, resulting in arch extrusion and support shoe slippage, causing damage to the completed primary support, and causing unsafe factors such as cave deformation and even roof collapse.

[0041] The on-site method generally uses sealed molds to cast early-strength concrete to improve the stress conditions of the surrounding rock. The problem is that sealing the molds and grouting and waiting for the concrete strength to recover usually takes about 10 hours, causing the construction surface to stop and occupying normal excavation time. This is the biggest obstacle affecting the progress of TBM construction.

[0042] To solve this problem, the idea of ​​using finished protection and force transmission materials is proposed. Traditional steel plates and concrete prefabricated blocks are heavy, difficult to assemble on site, and have low reuse rates. Therefore, the finished protection and force transmission materials are required to have certain strength and toughness, and low density, and are easy to install and disassemble. They can be reused while ensuring that the TBM can advance normally, reducing the investment in machinery and labor, and pursuing maximum benefits.

[0043] Therefore, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 6 As shown, the purpose of this embodiment is to provide a high-strength and lightweight composite plate that can be matched with TBM gripper shoes to transmit force, including a force transmission structure 1 and a bite fixing structure 2 arranged on the force transmission structure 1;

[0044] The force transmission structure 1 includes a plurality of superimposed solid plates 11, a laminated plate connector 12 and an anchor rod 13 arranged on the solid plates 11. The plurality of solid plates 11 are positioned and superimposed by the laminated plate connector 12, and the anchor rod 13 is used to fix the solid plates 11 on the bedrock.

[0045] The bite fixing structure 2 includes a movable part 21 arranged on both sides of the endurance plate 11 and a threaded bite body 22 arranged in the endurance plate 11. The movable part 21 is threadedly connected to the threaded bite body 22. The movable part 21 is used to control the threaded bite body 22 to bite and lock the anchor rod 13. After multiple endurance plates 11 are positioned and stacked through the stacking plate connector 12, the anchor rod 13 is passed through the endurance plate 11 and inserted into the bedrock. Then, by rotating the movable part 21, the movable part 21 drives the threaded bite body 22 to bite and lock the anchor rod 13, and the threaded bite body 22 will clamp the stacking plate connector 12, so that the stacking plate connector 12 combines multiple endurance plates 11 into a whole, thereby ensuring the structural strength of the composite plate.

[0046] The above structure is disclosed as follows:

[0047] First, if Figure 3 , Figure 4 , Figure 5As shown, the laminated plate connector 12 includes a fixing frame 121 and a positioning rod 122. The fixing frame 121 is embedded in the surface of the endurance plate 11. One end of the positioning rod 122 is engaged with the middle part of the fixing frame 121. The other end of the positioning rod 122 passes through the fixing frame 121. The endurance plate 11 is provided with a plurality of holes. One end of the anchor rod 13 is inserted into the bedrock through the holes. The other end of the anchor rod 13 is provided with a pad 131 and a nut 132. When positioning and stacking a plurality of endurance plates 11, a positioning rod 122 of a corresponding length is selected according to the number and thickness of the stacked endurance plates 11 to be inserted into the fixing frame 121, so that one end of the positioning rod 122 is stuck on the fixing frame 121, and the other end of the positioning rod 122 is locked in the fixing frame 121. One end passes through the fixing frame 121, and the other end of the positioning rod 122 is inserted into the fixing frame 121 on the other endurance plates 11, so as to realize the positioning and superposition of multiple endurance plates 11, and then one end of the anchor rod 13 passes through the hole through the multiple endurance plates 11 and is inserted into the bedrock. After the anchor rod 13 is subsequently fixed, a pad 131 is put on the other end of the anchor rod 13 and threadedly connected with the nut 132, so that the other end of the anchor rod 13 is stuck in the hole through the pad 131. It is worth noting that the structural shape of the pad 131 matches the structural shape of the hole, so that when the anchor rod 13 is fixed, the pad 131 can be stuck in the hole without shaking, thereby ensuring the fixing effect of the anchor rod 13.

[0048] It is worth noting that the endurance board 11 is a board composited with a solid polycarbonate endurance board and a high-strength carbon fiber cloth, and the high-strength carbon fiber cloth is composited with the force-bearing surface of the polycarbonate endurance board. According to the use characteristics, the high-strength carbon fiber cloth is selected to be grade I or grade II. The high-strength grade I carbon fiber cloth has a tensile strength of ≥3400MPa, and the high-strength grade II carbon fiber cloth has a tensile strength of ≥3000MPa. The polycarbonate endurance board is a widely used board in the market. It has super mechanical properties, high strength, high toughness, high heat resistance, high waterproofness, and excellent light transmittance and light weight. Its disadvantage is that the molding size is limited, with a maximum width of 3m, a maximum thickness of 2cm, and an unlimited length. In addition, bonding high-strength carbon fiber cloth is widely used in engineering to reinforce the surface of concrete and steel structures, with a tensile strength greater than 3000MPa. The present invention utilizes the characteristics of these two materials and uses special glue for bonding carbon fiber cloth for compounding, so as to maximize their compressive and tensile properties and produce an endurance plate 11 with high strength and lightness. When the support boot changes steps, the loss of the endurance plate 11 can be reduced, and the difficulty of disassembling and assembling the endurance plate 11 can be reduced, thereby reducing the TBM construction cost.

[0049] In addition, the curvature of the solid board 11 matches the curvature of the support shoe, and the board length is the support shoe length + 1000mm (in order to facilitate on-site installation, it can be spliced ​​in blocks, and the length of each section is 1000-1500mm). In order to adapt to the support parameters of different arch frames, the width of the solid board 11 is divided into three types: 300mm, 750mm, and 1600mm, and the board thickness is divided into two types: 20mm and 10mm. It can be stacked according to the thickness required on site, and the curvature is bent according to the size of the TBM support shoe. It is factory-produced or self-compounded on site, and can be used in multiple layers. In order to increase the bite force between the board and the bedrock and the board, and facilitate on-site assembly, circular anchors with a spacing of 500mm, a diameter of 30mm, and a depth of 10mm are evenly distributed within the board range. Six holes with a hole size of 30mm are opened on each endurance board 11, and the hole size is 30mm, which are respectively set at the upper, middle, and lower positions 100mm away from the edge of the board.

[0050] After a plurality of endurance plates 11 are initially stacked, and one end of the anchor rod 13 is inserted through the endurance plates 11 into the bedrock, Figure 6 , Figure 7 As shown, the movable part 21 includes a plate ear 211 and an adjuster 212. The plate ear 211 is connected to the middle of both sides of the endurance plate 11. The adjuster 212 includes an end shaft 2121 and a middle shaft 2122 arranged at one end of the end shaft 2121. The middle shaft 2122 is located in the plate ear 211. A screw sleeve 213 is also rotatably connected in the plate ear 211. One end of the screw sleeve 213 is meshed with the middle shaft 2122, and the other end of the screw sleeve 213 is threadedly connected to the threaded engaging body 22.

[0051] like Figure 4 , Fig. 9 , Fig.10 As shown, a first inner groove 111 communicating with the hole is provided in the middle of the endurance plate 11, and the threaded engaging body 22 includes an inner frame plate 221 located in the first inner groove 111, a screw shaft 2211 is provided at one end of the inner frame plate 221, and one end of the screw shaft 2211 is located in the screw sleeve 213 and is threadedly connected to the screw sleeve 213, a plate groove 2212 is provided on the inner frame plate 221, and a bite piece 222 for contacting the anchor rod 13 is slidably connected in the plate groove 2212, and the bite piece 222 is slidably connected to the inner wall of the first inner groove 111 up and down, as shown in FIG. Fig.11 As shown by the middle arrow a, by rotating the end shaft 2121, the end shaft 2121 drives the screw sleeve 213 meshed with the middle shaft 2122 to rotate. When the screw sleeve 213 rotates, the screw shaft 2211 threadedly connected to the screw sleeve 213 drives the inner frame plate 221 to move in the first inner groove 111. The moving direction of the inner frame plate 221 is as shown in FIG. Fig.10 As shown by the arrow b in the middle, since the bite piece 222 is connected to the inner wall of the first inner groove 111 by sliding up and down, when the inner frame plate 221 moves, the bite piece 222 is driven along the inner wall of the first inner groove 111 through the plate groove 2212. Fig.11Move in the direction indicated by the middle arrow c until the bite piece 222 contacts the surface of the anchor rod 13, and the anchor rod 13 is fixed under the clamping and bite of the upper and lower bite pieces 222. Then, the pad 131 is put on the other end of the anchor rod 13 and threadedly connected with the nut 132, so that the other end of the anchor rod 13 is stuck in the hole through the pad 131, completing the fixed connection between the endurance plate 11 and the bedrock.

[0052] Further, such as Figure 5 , Fig. 9 , Fig.10 As shown, a second inner groove 123 for exposing the positioning rod 122 is opened in the middle of the fixing frame 121, and the second inner groove 123 is connected to the first inner groove 111. A plurality of rod surface grooves 124 are correspondingly opened on the surface of the positioning rod 122. A bite plate 223 is slidably connected to the inner side of the inner frame plate 221 away from the screw shaft 2211. A spring is provided on the side of the bite plate 223 away from the positioning rod 122. The bite plate 223 is connected to the inner wall of the inner frame plate 221 through the provided spring. The rod surface groove 124 is a tooth-shaped groove, and the bite plate 223 is a convex tooth corresponding to the bite plate 223. By engaging with the rod face groove 124, the inner frame plate 221 can be driven by rotating the end shaft 2121, and then the bite plate 222 is driven to lock the anchor rod 13. The movement of the inner frame plate 221 will drive the bite plate 223 to contact and clamp the rod face groove 124, so that the multiple endurance plates 11 are fixedly connected through the stacked plate connector 12, and the multiple stacked endurance plates 11 can be combined into a whole while maintaining a fixed connection with the bedrock, and then connected to the anchor rod 13 through the pad 131 and the nut 132, thereby ensuring the structural strength of the plate.

[0053] like Figure 8 As shown, the middle axis 2122 is coaxially connected to the tail axis 2123 at one end away from the end axis 2121, and the end axis 2121 is provided with a slot 2124, and the slot 2124 matches the shape of the tail axis 2123. By providing the tail axis 2123 and the slot 2124, when multiple endurance plates 11 are positioned and stacked, the tail axis 2123 can be inserted into the slot 2124 of the adjacent endurance plate 11, and then when the end axis 2121 is driven to rotate through the slot 2124, the end axis 2121 of the adjacent endurance plate 11 can be driven to rotate synchronously, thereby facilitating the locking piece 222 in the adjacent endurance plate 11 to lock the anchor rod 13, and driving the locking plate 223 in the adjacent endurance plate 11 to clamp the rod face groove 124, so as to distribute the pressure on the locking piece 222 and the locking plate 223 in a multi-point contact manner, thereby ensuring the structural strength of the plate.
