Description

Technical Field

[0001] This utility model relates to the field of tunnel boring machine technology, specifically a tunnel boring machine stabilization device. Background Technology

[0002] A tunnel boring machine (TBM) is a type of tunnel excavation machine that uses the shield tunneling method. The shield tunneling method involves the tunnel boring machine constructing a "shield" for the tunnel while excavating. This method differs from the open tunneling method. In a broader sense, TBMs can also be used in rock formations, but they are different from open tunnel boring machines. In my country, however, tunnel boring machines used in soft soil formations are conventionally called TBMs, while those used in rock formations are called TBMs.

[0003] Existing technology publication CN220185114U discloses a shield tunneling machine stabilization device. The device comprises two housings mounted on the front of the machine body, with outer shells movably connected to the inner sides of each housing. A block is fixed to one side of the inner wall of each outer shell, and a controller is fixed to the inner side of the outer shell. A support shoe is movably connected to the inner side of the block. A monitoring mechanism is located below the support shoe, comprising a hydraulic cylinder, a square shell, a support block, a first spring, and a switch. The back of the hydraulic cylinder is fixedly connected to the back of the inner wall of the outer shell by bolts. The output end of the hydraulic cylinder is fixedly connected to the square shell by bolts. The inner wall and one side through hole of the square shell are movably connected to the outer wall of the support shoe. The bottom of the support shoe is fixedly connected to the inner wall of the square shell by two first springs. Two support blocks are fixedly connected to the inner side of the square shell, and a switch is installed on the inner side of the square shell. A plate is attached to the inner side of the outer shell, and a rod is fixedly connected to one side of the plate. The outer wall of the rod is movably connected to the inner through hole of the outer shell. The device is dynamically connected to the shield machine. One end of the rod is fixedly connected to a locking block. One side of the locking block is fixedly connected to the inner cavity of the outer shell via two second springs. The outer side of the locking block is movably connected to the cavity of the outer shell. The upper part of the outer wall of the locking block is movably connected to a through hole on one side of the outer shell and an inner groove on the outer shell. A curved rod is movably connected to a groove on one side of the plate. A rubber locking block is fixedly connected to the inner side of the curved rod. The outer side of the rubber locking block is movably connected to the inner groove on the plate. Through the cooperation between the square shell, the support block, and the first spring, real-time monitoring of whether the support shoe is damaged is achieved. This solves the problem that existing shield machines cannot promptly detect whether the support shoe is damaged during use. If the support shoe is damaged and not detected in time, it is easy for it to rotate during tunneling, which greatly reduces the stability of the shield machine. Through the cooperation between the locking block, the curved rod, and the hydraulic cylinder, a quick connection between the stabilizing device and the shield machine body is achieved, which is convenient for users to operate and improves work efficiency.

[0004] However, due to the poor multi-stabilization capability of the shield machine stabilization device in the existing technology CN220185114U, it is impossible to perform multiple stabilizations on the shield machine as needed during the actual use of the shield machine stabilization device. This makes it inconvenient to use the shield machine stabilization device stably and affects the user experience of the shield machine stabilization device. Utility Model Content

[0005] (a) Technical problems to be solved

[0009] The fixed column is movably equipped with a stabilizing spring column at one end, and a stabilizing disc is fixedly installed at one end of the stabilizing spring column. By improving the stabilizing device, the multiple stabilizing capabilities of the stabilizing device are improved. In the actual use of the stabilizing device, the tunnel boring machine can be stabilized in multiple ways as needed, which facilitates the stable use of the tunnel boring machine stabilizing device and improves the user experience of the tunnel boring machine stabilizing device.

[0010] The lower end of the segment hoisting pipe is fixedly equipped with a support block, the lower end of the support block is fixedly equipped with a crash plate, and the lower end of the support block is fixedly equipped with an electric push rod.

The use of the fixing ring facilitates the protection of the tunnel boring machine stabilizing device. The use of the extension disc and the cutter box improves the tunneling effect of the tunnel boring machine stabilizing device.

[0011] The lower end of the electric push rod is movably equipped with a push rod, and the lower end of the push rod is fixedly equipped with a support leg. By popping out the fixed column and the stabilizing spring column, the stabilizing plate is pushed to a suitable position, which improves the stabilizing effect of the shield machine stabilizing device. Then, the use of the support block and the anti-collision plate facilitates the support of the shield machine.

[0012] The segment hoisting pipe is fixedly provided with a fixed ring in the middle, and a movable ring is movably provided in the middle of the fixed ring.

[0013] The movable ring has a fixed electric push rod 2 at one end, a movable push rod 2 at one end, and a stabilizing support plate at one end. By moving the fixed ring and the movable ring, the electric push rod 2 and the push rod 2 can be moved to a suitable angle. Then, by controlling the extension and retraction of the electric push rod 2 and the push rod 2, the stabilizing support plate can be pushed to a suitable position, which facilitates the buffer support of the shield machine stabilization device.
