In the description of this utility model, it should be understood that if terms such as "upper," "lower," "left," "right," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this utility model. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0025] like Figures 1 to 3 As shown, this utility model provides a shield tunneling support device, which is used to support and adjust the tunneling posture of the tunneling machine 60. The tunneling machine 60 is placed on the shield tunneling support device, and the tunneling machine 60 can tunnel from the corresponding angle under the support and push of the shield tunneling support device, without the need to construct complex tunnels, launching and receiving structures.

[0026] The shield tunneling support device includes a base mechanism 10, a propulsion mechanism 30 mounted on the base mechanism 10, and four sets of support legs 40. The support legs 40 are hinged to opposite sides of the base mechanism 10. The support legs 40 are distributed on opposite sides of the base mechanism 10; that is, two sets of support legs 40 are provided on one side of the base mechanism 10, and another two sets of support legs 40 are provided on the opposite side. The four sets of support legs 40 constitute four drive points, each of which can operate independently or move in conjunction, thereby enabling the base mechanism 10 to move in pitch (forward and backward), tilt (left and right), and rise and fall (up and down).

[0027] The outrigger mechanism 40 is equipped with a power unit 41 for telescopic movement. The base mechanism 10 includes intersecting support seats 12 and reaction frames 11. The support seats 12 are used to support the tunnel boring machine 60. The power unit 41 adjusts the angle of the diagonal bracing of the outrigger mechanism 40 to adjust the pitch angle of the base mechanism 10. The outrigger mechanism 40 controls the angle of the diagonal bracing through the power unit 41 to adjust the attitude of the base mechanism 10, thereby realizing the automatic adjustment of the tunneling direction of the tunnel boring machine 60, which can adapt to tunneling at any angle.

[0028] Four sets of support mechanisms 40 are distributed at the four corners of the base mechanism 10. The support mechanisms 40 can be adjusted by the undulation of the power unit 41 to achieve different heights and pitch angles, thereby flexibly adjusting the tunneling angle of the tunneling machine 60 and achieving good adaptability.

[0029] After the tunneling machine 60 completes the adjustment of its tunneling direction, the propulsion mechanism 30 is installed on the reaction frame 11, with at least a portion of the propulsion mechanism 30 located within the projection range of the tunneling machine 60 on the reaction frame 11. The base mechanism 10 is equipped with the reaction frame 11, and the reaction frame 11 and the support base 12 form an integrated structure, which can be welded or locked together. The propulsion mechanism 30 adopts a hydraulic cylinder structure, which can push the tunneling machine 60 into the tunneling position. The entire shield support device can move flexibly, greatly improving the convenience of construction.

[0030] Preferably, the support base 12 and the reaction frame 11 intersect perpendicularly.

[0031] In one embodiment, the support base 12 is a rigid frame structure, and two support leg mechanisms 40 located on the same side of the support base 12 are symmetrically arranged.

[0032] The outrigger 42 is longer than the boom 43. The outrigger 42 is used to diagonally support the platform, which is the perimeter area of ​​the tunnel construction site. The first end of the outrigger 42 is hinged to the middle area of ​​the support base 12, and the second end of the outrigger 42 extends obliquely toward the end of the support base 12.

[0033] The first end of the swing arm 43 is hinged to the support base 12 and located near the end region of the support base 12. The power unit 41 is configured as a hydraulic cylinder, with its cylinder body hinged to the second end of the swing arm 43. The output shaft of the power unit 41 is hinged to the middle of the outrigger 42. The power unit 41 is hinged to both the end of the swing arm 43 and the middle of the outrigger 42, with the end of the outrigger 42 tilted away from the center of the base mechanism 10. When the power unit 41 extends or retracts, it can cause the outrigger 42 to swing and adjust the support angle.

[0034] The middle part of the outrigger 42 connected to the power unit 41 is the area, including but not limited to the midpoint of the outrigger 42.

[0035] More preferably, the support mechanism 40 further includes a support shoe 44 hinged to the support leg frame 42. The support shoe 44 is located at the second end of the support leg frame 42 and can rotate relative to the support leg frame 42, thereby adjusting the force-bearing connection part of the support mechanism 40 to always be perpendicular to the support platform. The support mechanism 40 and the support platform can be fixed by welding or expansion bolts to fix the support shoe 44.

[0036] Preferably, the support shoe 44 and the support leg frame 42 are rotatably connected by a pin, wherein the bottom of the support shoe 44 is provided with a support plate to increase the contact area between the support shoe 44 and the support platform.

[0037] The swing arm 43 can be configured as a support arm or a curved arm for hinged connection. In a preferred embodiment, the swing arm 43 is C-shaped and the first connection point between the swing arm 43 and the power unit 41 and the second connection point between the swing arm 43 and the support base 12 are connected by a curved arm. When the power unit 41 moves telescopically, the position of the force support point is changed, which can realize the rapid response of the outrigger 42 and the good force support effect without self-locking interference.

[0038] Each of the four outrigger mechanisms 40 is equipped with a power unit 41, which can be controlled synchronously or independently by the control system to achieve fine-tuning of the angle. Each power unit 41 can be adjusted independently to achieve each angle adjustment; the two outrigger mechanisms 40 located at the front can be paired and linked to form a pitch angle adjustment mechanism.

[0039] In one embodiment, the shield tunneling support device further includes an adjusting seat mechanism 20 mounted on the support base 12. The adjusting seat mechanism 20 has a recessed receiving groove 21 for defining the tunneling machine 60. The adjusting seat mechanism 20 can be adapted to one or more tunneling machines 60. The adjusting seat mechanism 20 is mounted on the support base 12, reducing the structural complexity of the support base 12. The mechanism for defining the position of the tunneling machine 60 is set in the adjusting seat mechanism 20 to improve the overall utilization rate of the base mechanism 10.

[0040] The receiving groove 21 is an arc-shaped or curved recessed structure, which can center the outer peripheral wall of the tunneling machine 60 so that the tunneling machine 60 can automatically align at the receiving groove 21.

[0041] The adjusting seat mechanism 20 is detachably connected to the support seat 12, for example, the adjusting seat mechanism 20 and the support seat 12 are locked together by fasteners; or, the adjusting seat mechanism 20 and the support seat 12 are connected by welding; or, the adjusting seat mechanism 20 and the support seat 12 are connected by a transition structure.

[0042] like Figures 1 to 4 As shown, in one embodiment, the adjusting seat mechanism 20 is rotatably connected to the support seat 12; the adjusting seat mechanism 20 is capable of rotating relative to the support seat 12, and this rotation is planar rotation. That is, the adjusting seat mechanism 20 rotates relative to the upper surface of the support seat 12.

[0043] Specifically, the bottom of the adjusting seat mechanism 20 is provided with a plug seat 24, and the support seat 12 is equipped with a rotary seat 13. The plug seat 24 is inserted into the rotary seat 13 to form a rotatable connection. Furthermore, a bearing is provided between the plug seat 24 and the rotary seat 13 to improve rotational flexibility.

[0044] In one embodiment, the shield tunneling support device further includes a swing adjustment mechanism 50 connecting the base mechanism 10 and the adjustment seat mechanism 20. The swing adjustment mechanism 50 drives the adjustment seat mechanism 20 to swing relative to the support base 12. The swing adjustment mechanism 50 locks the relative position of the adjustment seat mechanism 20 and the mounting base, thereby maintaining the stability of the position of the adjustment seat mechanism 20. The swing adjustment mechanism 50 is connected to the end of the adjustment seat mechanism 20. When the swing adjustment mechanism 50 extends or retracts, it can drive the adjustment seat mechanism 20 to swing relative to the base mechanism 10, thereby achieving swing angle adjustment.

[0045] Preferably, the swing adjustment mechanism 50 includes rotary adjustment cylinders 51 distributed on both sides of the adjustment seat mechanism 20. Two or more rotary adjustment cylinders 51 are connected to the adjustment seat mechanism 20, which can improve the swing flexibility of the adjustment seat mechanism 20 and maintain the stability of the swing angle of the adjustment seat mechanism 20, thereby improving the connection strength.

[0046] Furthermore, the adjusting seat mechanism 20 includes an adjusting seat 22, a front and rear push-pull assembly 23, and a sliding seat that slides on the adjusting seat 22. The front and rear push-pull assembly 23 connects the adjusting seat 22 and the sliding seat, and pushes the sliding seat along the adjusting seat 22. The adjusting seat 22 and the sliding seat are slidably connected, allowing the sliding seat to extend and retract, which facilitates the adjustment of the initial state of the tunneling machine 60. The front and rear push-pull assembly 23 connects the adjusting seat 22 and the sliding seat to act as the power output for the forward and backward movement of the sliding seat, thereby cooperating with the movement of the propulsion mechanism 30 and improving the attitude adjustment flexibility of the tunneling machine 60.

[0047] It should be understood that this application is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. This application is intended to cover any variations, uses, or adaptations of the present invention that follow the general principles of this application and include common knowledge or customary technical means in the art that are not disclosed in this invention.
