[0027] like Figures 1 to 4 As shown, the present invention provides a sleeve adjustment device, which is mounted on a support platform 10 and is used to adjust the connection posture of a sleeve device 70. The sleeve adjustment device includes a lifting mechanism 20 and an adjustment frame device. The adjustment frame device is mounted on the top of the support platform 10 and is used to support the sleeve device 70. The support platform 10 is a rigid structure, and the lifting mechanism 20 can drive the support platform 10 to move up and down as a whole. Accordingly, the sleeve device 70 is mounted on the adjustment frame device to form an overall lifting adjustment, so that the center line of the sleeve device 70 is at different heights, which can achieve a large range of height adjustment.

[0028] Furthermore, the lifting mechanism 20 includes at least two groups of lifting components 21, which are spaced apart on opposite sides of the support platform 10. The lifting components 21 are movable to adjust the total height and / or tilt angle of the support platform 10. Multiple groups of lifting components 21 are spaced apart on the support platform 10, and each group of lifting components 21 can be controlled individually, or multiple lifting components 21 can be controlled synchronously to enrich the posture adjustment of the support platform 10 and subsequently adjust the movement posture of the sleeve device 70. Optionally, the number of lifting components 21 can be set to two, three, four, five, six, or eight groups. The lifting components 21 are distributed on both sides of the support platform 10 to lift the support platform.

[0029] In one embodiment, four groups of lifting assemblies 21 are provided, and the four groups of lifting assemblies 21 are distributed on opposite sides of the support platform 10. The two groups of lifting assemblies 21 are located on the same side of the support platform 10. When the two lifting assemblies 21 on the same side are raised and lowered synchronously, the inclination angle of the center line of the sleeve device 70 in the vertical direction can be adjusted. When the two lifting assemblies 21 located at the same end of the support platform 10 are raised and lowered, the lateral angle of the sleeve device 70 can be adjusted. Optionally, the center point connection line of the four groups of lifting assemblies 21 is rectangular, and the four groups of lifting assemblies 21 are distributed in a rectangular shape to form a balanced lifting distribution. Alternatively, the center lines of the four groups of lifting assemblies 21 are trapezoidal, rhombus-shaped or other four-point positioning support structures.

[0030] The adjustment frame assembly, combined with the support platform 10, supports the sleeve assembly 70. The lifting mechanism 20 drives the support platform 10 to move upward and downward as a whole, thereby adjusting the center of the sleeve assembly 70 to different heights. Each lifting assembly 21 can also move upward and downward independently to adjust the sleeve assembly 70 to different tilt angles, providing high adjustment flexibility.

[0031] In a specific embodiment, four support frames 22 are installed on the side of the support platform 10, and a set of lifting components 21 are installed on each support frame 22. The lifting components 21 can be adjusted by using hydraulic cylinder components, screw components or pads.

[0032] The adjustment frame assembly enables further fine adjustments to the sleeve assembly 70, thereby further enhancing ease of adjustment. In one embodiment, the adjustment frame assembly includes an adjustment frame 40 movably connected to the support platform 10 and a translation mechanism 30 connected to the adjustment frame 40. The adjustment frame 40 restrains and supports the sleeve assembly 70. The adjustment frame 40 is mounted on the support platform 10 to support and restrain the sleeve assembly 70. Preferably, the adjustment frame 40 is provided with a positioning groove, into which the sleeve assembly 70 is hoisted, thereby ensuring a stable position of the sleeve assembly 70 on the adjustment frame 40.

[0033] The translation mechanism 30 is connected to the adjustment frame 40. The translation mechanism 30 drives the adjustment frame 40 to translate along the support platform 10 to adjust the axial position and / or axial swing angle of the sleeve device 70. The adjustment frame 40 slides on the surface of the support platform 10, and the translation mechanism 30 serves as a power output mechanism to push the adjustment frame 40 to slide along the surface of the support platform 10. For example, the translation mechanism 30 uses a hydraulic cylinder assembly, which telescopes and drives the adjustment frame 40 along the support platform. Alternatively, the translation mechanism 30 uses a screw-nut mechanism, in which the motor portion is mounted on the support platform 10 and the nut portion is connected to the adjustment frame 40. The screw mechanism rotates to drive the nut portion to rotate, thereby precisely moving the adjustment frame 40.

[0034] In one embodiment, the translation mechanism 30 includes at least one power member 31 and a translation transmission assembly 32 connected to the power member 31. The translation transmission assembly 32 is connected to the adjustment frame 40. The power member 31 drives the translation transmission assembly 32 to move, and the translation transmission assembly 32 drives the adjustment frame 40 to adjust its posture.

[0035] The translation mechanism 30 adopts one or more power output parts to achieve different posture adjustment power output. Optionally, the translation transmission assembly 32 is set as one, and one translation transmission assembly 32 drives the adjustment frame 40 to move to form a single-point fixed-point output. In a preferred embodiment, two power members 31 are provided, and each power member 31 and the translation transmission assembly 32 are correspondingly connected. The two translation transmission assemblies 32 are spaced apart on the adjustment frame 40, and each power member 31 drives the translation transmission assembly 32 to operate independently, wherein, when one translation transmission assembly 32 moves and the other translation transmission assembly 32 does not move, the adjustment frame 40 can rotate slightly on the horizontal plane of the support platform 10. The two translation transmission assemblies 32 move synchronously, which can drive the adjustment frame 40 to move translationally on the support platform 10.

[0036] In one embodiment, the translation mechanism 30 uses a translation hydraulic cylinder, which is distributed on one side or two opposite sides of the support platform 10. The translation transmission assembly 32 is configured as an articulated joint to flexibly push the adjustment frame 40 to translate.

[0037] In another embodiment, the translation mechanism 30 adopts a screw-nut mechanism, the translation transmission assembly 32 is a screw portion installed on the adjustment frame 40, and a coupling is provided in the power transmission portion to achieve movable connection operation.

[0038] The translation mechanism 30 enables the sleeve assembly 70 to move in the axial direction and swing in the plane of the axis, thereby achieving planar posture adjustment. Furthermore, the adjustment frame device is also provided with a horizontal adjustment mechanism 50, which is used to adjust the translation movement of the sleeve assembly 70 in a direction perpendicular to the axis to achieve precise radial position adjustment.

[0039] The adjustment frame assembly includes a horizontal adjustment mechanism 50 connecting the support platform 10 and the adjustment frame 40. The movable adjustment direction of the horizontal adjustment mechanism 50 intersects the adjustment direction of the translation mechanism 30. The fixed end of the horizontal adjustment mechanism 50 is mounted on one of the support platform 10 and the adjustment frame 40, while the movable end of the horizontal adjustment mechanism 50 is mounted on the other of the support platform 10 and the adjustment frame 40. The horizontal adjustment mechanism 50 is connected via telescopic movement or a screw mechanism to achieve translational adjustment of the adjustment frame 40 on the support platform 10, thereby adjusting the radial position of the sleeve assembly 70.

[0040] Furthermore, the horizontal adjustment mechanism 50 includes at least one horizontal telescopic assembly 51, which is connected to one side of the adjustment frame 40. The horizontal telescopic assembly 51 is connected to the middle of the adjustment frame 40 to push the adjustment frame 40 to move as a whole, making adjustment convenient. Further preferably, two horizontal telescopic assemblies 51 are arranged at intervals on one side of the adjustment frame 40, and the two horizontal telescopic assemblies 51 respectively push the adjustment frame 40 to move, thereby achieving independent adjustment or joint adjustment. Specifically, when the two horizontal telescopic assemblies 51 are adjusted independently, the adjustment frame 40 can be swung at both ends. When the two horizontal telescopic assemblies 51 are adjusted jointly, the adjustment frame 40 can be horizontally translated.

[0041] Furthermore, at least two horizontal telescopic assemblies 51 are provided, and are respectively distributed on both sides of the adjustment frame 40, and both horizontal telescopic assemblies 51 are connected to the adjustment frame 40. The horizontal telescopic assemblies 51 are distributed on both sides of the adjustment frame 40. On the basis of the above embodiment, the flexibility of adjusting the adjustment frame 40 in two directions can be further improved.

[0042] As an advantage, the horizontal telescopic assembly 51 can be a hydraulic cylinder mechanism. Further, the horizontal telescopic assembly 51 can be a hydraulic cylinder mechanism in combination with a pad or a wedge or other connecting piece.

[0043] The translation mechanism 30 and the horizontal adjustment mechanism 50 can adjust the front, back, left, and right positions of the adjustment frame 40 and adjust the swing angle on the plane of the support platform 10. Accordingly, the sleeve device 70 can simultaneously achieve the above-mentioned plane position and angle adjustment.

[0044] Furthermore, the connection between the sleeve device 70 and the tunnel portal is an annular flat surface or curved surface. For example, during the construction of a connecting passage, the sleeve device 70 is welded to the steel pipe segment 80 in the main tunnel, and the welded end surface of the sleeve device 70 is configured as a convex arc-shaped curved surface. To further adjust the end surface posture of the sleeve device 70, after completing the planar position adjustment of the sleeve device 70, the sleeve device 70 can be further rotated to achieve more precise weld surface alignment.

[0045] In one embodiment, the adjustment frame device includes a rotation adjustment mechanism 60 mounted on the support platform 10 or the adjustment frame 40. The output end of the rotation adjustment mechanism 60 is connected to the outer peripheral wall of the sleeve device 70. The rotation adjustment mechanism 60 telescopically moves to drive the sleeve device 70 to rotate and adjust its posture. The rotation adjustment mechanism 60 is directly connected to the sleeve device 70 to drive the sleeve device 70 to rotate relative to the adjustment frame 40 to adjust the end face angle of the sleeve device 70. Preferably, the rotation adjustment mechanism 60 can be adjusted by pushing. For example, the rotation adjustment mechanism 60 can use a hydraulic cylinder mechanism or a wedge mechanism to lift one side of the sleeve device 70 to achieve rotational adjustment of the sleeve device 70.

[0046] In one embodiment, the rotation adjustment mechanism 60 includes at least one set of rotating and telescopic assemblies 61, which are distributed on one side of the adjustment frame 40. The rotating and telescopic assemblies 61 can be configured as hydraulic cylinders, wherein the hydraulic cylinders are mounted on the support platform 10 or the adjustment frame 40, and the output end is connected to the sleeve device 70. The center of the hydraulic cylinder is tilted or perpendicular to the platform of the support platform 10, thereby driving the sleeve device 70 to rotate in a tangential or oblique direction.

[0047] In another preferred embodiment, the rotating and telescopic assemblies 61 are distributed on both sides of the adjustment frame 40, and the hydraulic cylinders on both sides of the sleeve device 70 synchronously push and pull the sleeve device 70 to rotate. Alternatively, the hydraulic cylinders on both sides synchronously push the sleeve device 70 tangentially to rotate, thereby improving the flexibility of rotation.

[0048] On the basis of the above embodiment, the support platform 10 is configured as a starting trolley, and the starting trolley is provided with running wheels 11. The starting trolley is the basic platform for tunnel construction. Using the starting trolley as the support platform 10 can not only directly carry the sleeve device 70 to the portal area, but also directly adjust the posture on the starting trolley to avoid intermediate movement. Alternatively, the support platform 10 is a rigid platform. As a structurally stable platform structural component, the rigid platform is installed on the starting trolley or as part of the starting trolley, thereby facilitating replacement and disassembly.
