Description

Technical Field

[0001] This invention relates to the field of tunnel construction technology, and in particular to a box culvert assembly device. Background Technology

[0002] Tunnels constructed using the shield tunneling method typically require the installation of precast box culverts as road surfaces on the segmental tunnel sections. Precast box culverts are characterized by their large structural dimensions, heavy weight, and high installation precision requirements. Currently, the assembly of precast box culverts in tunnels is primarily carried out using box culvert cranes, which mostly employ C-shaped, M-shaped, or L-shaped clamps for lifting the box culverts.

[0003] Because the box culvert hoisting method requires a large clearance inside the tunnel, the posture of the box culvert components is not fixed each time it is hoisted, and the function of adjusting the posture of the box culvert is relatively weak, resulting in long assembly time, low precision, and high failure rate. Summary of the Invention

[0004] In view of the above problems, the present invention provides a box culvert assembly equipment, which can improve the assembly accuracy and efficiency of box culverts, make the posture of box culverts more stable during the assembly process, help improve assembly efficiency and operational safety, and requires less clearance.

[0005] This invention provides a box culvert assembly device for assembling box culverts on tunnel segments. The box culvert has an inner working culvert, and its bottom wall has a perforation. The working culvert communicates with the tunnel segments through the perforation. The box culvert assembly device includes: a support mechanism, comprising a support base and a lifting column. The support base is adapted to support the tunnel segments, and the lifting column is movably mounted on the support base, extending through the perforation into the working culvert; a translation mechanism, comprising multiple interconnected translation seats, which are movable relative to each other and configured to translate relative to the support mechanism in different directions; a gripping mechanism for positioning and gripping the box culvert, which is movably connected to the translation seat with the highest degree of freedom among the multiple translation seats; and a swaying mechanism, comprising multiple swaying drive members, which are respectively connected to the gripping mechanism and the translation seat with the highest degree of freedom, and are configured to drive the gripping mechanism to sway at different angles.

[0006] According to the box culvert assembly equipment of the present invention, the translating mechanism enables the gripping mechanism to translate in multiple directions, and the oscillating mechanism enables the gripping mechanism to oscillate at multiple different angles. Through the cooperation of the translating and oscillating mechanisms, the gripping mechanism has multiple degrees of freedom, allowing for fine-tuning of the box culvert's position within a small angle and distance range, thus improving the assembly accuracy of the box culvert. Furthermore, compared to related technologies that use cranes and clamps to lift and assemble box culverts, the equipment as a whole can be supported by a support mechanism on the tunnel segments serving as bottom supports, resulting in a more stable posture of the box culvert during assembly. The equipment can also flexibly adjust the box culvert's posture, contributing to improved assembly efficiency and operational safety. Additionally, because the main structure of the equipment is located inside the box culvert, the clearance requirements for the tunnel are lower during assembly.

[0007] In some embodiments, the inner wall of the box culvert is provided with a positioning structure, and the gripping mechanism includes: a lifting base, which is ball-jointed with the translation seat with the highest degree of freedom among a plurality of translation seats; and a gripping structure, which is disposed on the side surface of the lifting base opposite to the swaying mechanism, and the gripping structure is configured to position and cooperate with the positioning structure.

[0008] In some embodiments, the positioning structure includes a positioning hole, and the gripping structure is configured as a positioning pin that positions and engages with the positioning hole.

[0009] In some embodiments, the plurality of translation seats include: a first translation seat, the two ends of which are respectively connected to the two lifting columns; a second translation seat, which is movably disposed on the first translation seat along the axial direction of the tube segment; and a third translation seat, which is movably disposed on the second translation seat along the radial direction of the tube segment, wherein the lifting base is ball-jointed with the third translation seat.

[0010] In some embodiments, the translation mechanism further includes: a first driving member disposed on the first translation seat and convexly connected to the second translation seat to drive the second translation seat to move relative to the first translation seat; and a second driving member disposed on the second translation seat and convexly connected to the third translation seat to drive the third translation seat to move relative to the second translation seat.

[0011] In some embodiments, the top wall of the third translation seat is provided with a ball seat, the ball seat defining a movable cavity, and the lifting base is provided with a first ball head, the first ball head being slidably disposed within the movable cavity relative to the ball seat.

[0012] In some embodiments, the plurality of yaw drive components include: a first yaw cylinder, one end of which is pivotally connected to one sidewall of the third translation seat along the radial direction of the tube segment, and the other end of which is pivotally connected to one end of the bottom wall of the support base along the radial direction of the tube segment; a second yaw cylinder, one end of which is pivotally connected to one sidewall of the third translation seat along the axial direction of the tube segment, and the other end of which is pivotally connected to one sidewall of the support base along the axial direction of the tube segment; and a third yaw cylinder, which is arranged along the axial direction of the tube segment between the support base and the third translation seat, and both ends of which are pivotally connected to the support base and the third translation seat, respectively.

[0013] In some embodiments, the support base is configured to make the lifting column vertical when supported on the arcuate inner wall of the tube segment.

[0014] In some embodiments, the support includes: a first body having a support surface adapted to conform to the inner wall of the tube segment, the first body further defining a ball head mounting cavity; a second body having a second ball head extending into the ball head mounting cavity, the second ball head being adapted to deflect within the ball head mounting cavity, and the bottom end of the lifting column being connected to the second body.

[0015] In some embodiments, the support base further includes a pad, the pad being disposed on the support surface to support the first base when the first base body is supported on the inner wall of the tube segment. Attached Figure Description

[0036] To make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0037] Tunnels constructed using the shield tunneling method typically require the installation of precast box culverts as road surfaces on the tunnel segments. These precast box culverts are characterized by their large structural dimensions, heavy weight, and high installation precision requirements. Currently, the assembly of precast box culverts in tunnels primarily utilizes box culvert cranes, which mostly employ C-shaped, M-shaped, or L-shaped clamps for lifting. Due to the box culvert lifting method, a large clearance is required within the tunnel. Furthermore, the box culvert's posture is not fixed during each lifting operation, and the cranes have limited adjustment capabilities, resulting in long assembly times, low precision, and a high rate of defective products.

[0038] In view of this, the present invention provides a box culvert assembly device. A translation mechanism enables the gripping mechanism to translate in multiple directions, and a swing mechanism enables the gripping mechanism to swing at multiple different angles. Through the cooperation of the translation and swing mechanisms, the gripping mechanism has multiple degrees of freedom, allowing for fine-tuning of the box culvert's position within a small angle and distance range, thus improving the assembly accuracy. Furthermore, since the entire device is supported by a support mechanism on the tunnel segments serving as the bottom support, the box culvert's posture is relatively stable during assembly, contributing to improved assembly efficiency and operational safety.

[0039] The following is for reference. Figures 1-3 The assembly equipment 100 for box culvert 200 according to an embodiment of the present invention is described.

[0040] Specifically, refer to Figure 1 and Figure 2 The box culvert 200 assembly equipment 100 of this embodiment can be used to assemble box culverts 200 on tunnel segments 300. The inner side of the box culvert 200 has a working culvert 201, and the bottom wall of the box culvert 200 is provided with perforations. The working culvert 201 is connected to the tunnel segments 300 through the perforations. The box culvert 200 assembly equipment 100 may include: a support mechanism 1, a translation mechanism 2, a gripping mechanism 3, and a tilting mechanism 4.

[0041] The support mechanism 1 may include a support base 11 and a lifting column 12. The support base 11 is adapted to support the tunnel segment 300. The lifting column 12 is movably mounted on the support base 11 and extends through a perforation into the working culvert 201. There are at least two lifting columns 12, which are arranged opposite to each other and spaced apart along the width direction of the box culvert 200. The portions of the two lifting columns 12 within the working culvert 201 can jointly define the installation space. The support mechanism 1 provides installation support for the translation mechanism 2, the gripping mechanism 3, and the swaying mechanism 4, and drives each mechanism to perform lifting movements, thereby realizing the lifting of the box culvert 200 relative to the tunnel segment 300.

[0042] The translation mechanism 2 may include multiple translation seats, which are connected to each other and can move relative to each other. The multiple translation seats are configured to translate relative to the support mechanism 1 in different directions. In this way, the gripping mechanism 3 and the swaying mechanism 4 provided on the translation mechanism 2 can translate in multiple directions with the translation mechanism 2, thereby realizing the translation of the box culvert 200 in multiple directions and adjusting the position of the box culvert 200.

[0043] The gripping mechanism 3 can be used to position and grip the box culvert 200. The gripping mechanism 3 is movably connected to the translation seat with the highest degree of freedom among multiple translation seats, such as the third translation seat 23 described below. Here, the degree of freedom refers to the number of independent coordinates required to determine the position of the translation seat in space. The translation seat with the highest degree of freedom is the one with the most motion forms among multiple translation seats. In this way, the gripping mechanism 3 can be ensured to have a high degree of freedom, which helps to flexibly adjust the position of the box culvert 200 and achieve high-precision assembly of the box culvert 200.

[0044] The yaw mechanism 4 may include multiple yaw drive members, which are respectively connected to the gripping mechanism 3 and the translation seat with the highest degree of freedom. The multiple yaw drive members are configured to drive the gripping mechanism 3 to swing at different angles. In this way, the yaw mechanism 4 can drive the gripping mechanism 3 to swing at multiple different angles.

[0045] According to an embodiment of the present invention, the box culvert 200 assembly equipment 100 can realize the translational movement of the gripping mechanism 3 in multiple directions through the translation mechanism 2, and the swing mechanism 4 can realize the swinging of the gripping mechanism 3 at multiple different angles through the swing mechanism 4. Through the cooperation of the translation mechanism 2 and the swing mechanism 4, the gripping mechanism 3 has multiple degrees of freedom, realizing the fine adjustment of the position of the box culvert 200 within a small angle and small distance range, thereby improving the assembly accuracy of the box culvert 200. Furthermore, compared with the related technology that uses cranes and clamps to lift the box culvert 200 for assembly, since the entire equipment can be supported on the tunnel segments 300 as the bottom support by the support mechanism 1, the posture of the box culvert 200 is more stable during the assembly process, and the equipment can adjust the posture of the box culvert 200 more flexibly, which helps to improve the assembly efficiency and operational safety. In addition, since the main structure of the equipment is located inside the box culvert 200, the clearance requirements of the tunnel are lower during the assembly operation.

[0046] In some embodiments, reference Figure 1 and Figure 2 The inner wall of the box culvert 200 may be provided with a positioning structure, such as a positioning hole, positioning groove, positioning protrusion, positioning bolt, positioning pin, etc. Of course, the present invention does not limit this, and the positioning structure may also be constructed as any other structure that facilitates the gripping mechanism 3 to position and connect the box culvert 200.

[0047] The gripping mechanism 3 may include a lifting base 31 and a gripping structure 32. The lifting base 31 may be constructed in the shape of a square platform. The lifting base 31 is ball-jointed with the translation seat with the highest degree of freedom among multiple translation seats, thus ensuring that the lifting base 31 has a high degree of freedom. The gripping structure 32 is provided on the side surface of the lifting base 31 facing away from the yaw mechanism 4. The gripping structure 32 is constructed to cooperate with the positioning structure. For example, when the positioning structure of the inner wall of the box culvert 200 is a positioning hole or a positioning groove, the gripping structure 32 may be formed as a positioning pin; when the positioning structure of the inner wall of the box culvert 200 is a positioning protrusion, a positioning bolt, or a positioning pin, the gripping structure 32 may be formed as a positioning hole, a positioning groove, or a positioning claw, etc. Of course, the present invention does not limit this, and the gripping structure 32 can be reasonably designed according to the construction of the positioning structure. Thus, the lifting base 31 facilitates the connection between the gripping mechanism 3, the swaying mechanism 4, and the translation mechanism 2. It can also be used to support the box culvert 200. The gripping structure 32 ensures a stable connection between the gripping mechanism 3 and the box culvert 200, maintaining a stable relative posture and preventing misalignment of the box culvert 200 during posture adjustments, making it safer and more reliable. The overall structure is relatively simple and easy to manufacture.

[0048] In a specific example, the positioning structure may include a positioning hole, and the gripping structure 32 may be a positioning pin, which engages with the positioning hole for positioning. This simplifies the structure and makes it easier for the gripping mechanism 3 to position the box culvert 200.

[0049] In some embodiments, reference Figure 1 and Figure 2The multiple translation seats may include: a first translation seat 21, a second translation seat 22, and a third translation seat 23. The first translation seat 21 extends radially along the segment 300, and its two ends are connected to two lifting columns 12, respectively, allowing it to move up and down with the lifting columns 12. The second translation seat 22 is movably disposed on the first translation seat 21 along the axial direction of the segment 300, allowing it to both move up and down with the first translation seat 21 and move relative to it along the axial direction of the segment 300. The third translational seat 23 is movably disposed on the second translational seat 22 along the radial direction of the tube segment 300. Thus, the third translational seat 23 can move up and down together with the second translational seat 22 along with the first translational seat 21, and can also move relative to the second translational seat 22 along the axial direction of the tube segment 300, and can also translate relative to the second translational seat 22 along the radial direction of the tube segment 300. The lifting base 31 is ball-jointed with the third translational seat 23. Thus, the lifting base 31 can move in the same way as the third translational seat 23, and can also swing relative to the third translational seat 23. This gives the gripping mechanism 3 a high degree of freedom, enabling high-precision adjustment of the box culvert 200's position. Furthermore, the overall structure is relatively simple, facilitating manufacturing and assembly.

[0050] In some embodiments, the top wall of the first translation seat 21 has a first slide rail, which extends axially along the tube 300, and the bottom wall of the second translation seat 22 has a first sliding fit structure. For example, the first sliding fit structure can be a slider or a pulley. The first sliding fit structure is adapted to the first slide rail and is suitable for sliding relative to the first slide rail. In this way, the translation of the second translation seat 22 can be realized, and the structure is simple and reliable.

[0051] In some embodiments, the top wall of the second translation seat 22 is provided with flanges extending outward along the axial direction of the tube 300 on both opposite sides. The flanges extend in the radial direction of the tube 300 and can form a second slide rail. The bottom of the third translation seat 23 is provided with a second slide groove that is adapted to the second slide rail. The second slide rail fits into the second slide groove. In this way, the third translation seat 23 can move relative to the second translation seat 22, and the structure is simple and reliable.

[0052] In some embodiments, reference Figure 1 and Figure 2The translation mechanism 2 may further include a first driving member 24 and a second driving member 25. Specifically, the first driving member 24 is disposed on the first translation seat 21 and is connected to the second translation seat 22 in a transmission manner to drive the second translation seat 22 to move relative to the first translation seat 21. For example, the first driving member 24 may be one of a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder. The fixed end of the first driving member 24 is connected to the first translation seat 21, and the piston of the first driving member 24 is connected to the second translation seat 22. The movement of the second translation seat 22 is realized by the extension and retraction of the piston of the first driving member 24.

[0053] The second driving member 25 is disposed on the second translation seat 22 and is connected to the third translation seat 23 in a transmission manner to drive the third translation seat 23 to move relative to the second translation seat 22. For example, the second driving member 25 can be one of a hydraulic cylinder, a pneumatic cylinder or an electric cylinder. The fixed end of the second driving member 25 is connected to the second translation seat 22, and the piston of the second driving member 25 is connected to the third translation seat 23. The movement of the third translation seat 23 is realized by the extension and retraction of the piston of the second driving member 25.

[0054] In some embodiments, reference Figure 2 The inner side of the third translation seat 23 defines an assembly cavity that extends radially along the tube segment 300. The second driving member 25 is horizontally disposed within the assembly cavity and is connected to both the second translation seat 22 and the third translation seat 23, thereby enabling the movement of the third translation seat 23. In this way, when the third translation seat 23 has a high degree of freedom (i.e., when there are many driving members driving the third translation seat 23), the space inside the third translation seat 23 can be fully utilized, reducing the occupation of the space outside the third translation seat 23. This facilitates the optimization of the structural layout of the translation mechanism 2 and the oscillation mechanism 4, and makes the overall assembly of the equipment easier.

[0055] In some embodiments, the top wall of the third translation seat 23 is provided with a ball seat, which defines a movable cavity. The lifting base 31 is provided with a first ball head, which is slidably disposed in the movable cavity relative to the ball seat. In this way, when the swing mechanism 4 is connected to the third translation seat 23 and the lifting base 31 respectively, the lifting base 31 can be deflected in multiple directions. At the same time, the cooperation between the third translation seat 23 and the lifting base 31 is relatively simple, and easy to assemble and maintain.

[0056] In some embodiments, reference Figure 1 and Figure 2The multiple yaw drive components may include: a first yaw cylinder 41, a second yaw cylinder 42, and a third yaw cylinder 43. Specifically, one end of the first yaw cylinder 41 is pivotally connected to one side wall of the third translation seat 23 along the radial direction of the tube segment 300, and the other end is pivotally connected to one end of the bottom wall of the lifting base 31 along the radial direction of the tube segment 300. Thus, the first yaw cylinder 41 can drive the lifting base 31 to deflect axially around the tube segment 300. One end of the second yaw cylinder 42 is pivotally connected to one side wall of the third translation seat 23 along the axial direction of the tube segment 300, and the other end is pivotally connected to one side wall of the lifting base 31 along the axial direction of the tube segment 300. Thus, the second yaw cylinder 42 can drive the lifting base 31 to deflect axially around the horizontal radial line of the tube segment 300. The third sway cylinder 43 is arranged along the axial direction of the tube segment 300 between the lifting base 31 and the third translational seat 23. The two ends of the third sway cylinder 43 are pivotally connected to the lifting base 31 and the third translational seat 23 respectively. In this way, the third sway cylinder 43 can drive the lifting base 31 to deflect around the vertical diameter line of the tube segment 300.

[0057] Understandably, since the sway mechanism 4 is located between the third translation seat 23 and the lifting base 31, the gripping mechanism 3 has both the three translational degrees of freedom of the translation mechanism 2 and the three rotational degrees of freedom of the sway mechanism 4, that is, the gripping mechanism 3 has six degrees of freedom. In this way, the box culvert 200 assembly equipment 100 can flexibly and accurately adjust the angle and position of the box culvert 200, and the assembly efficiency is high, the cost is low, and the space occupied is small.

[0058] In some embodiments, combined with Figure 1 and Figure 3 The support base 11 can be configured to keep the lifting column 12 vertical when supported on the arc-shaped inner wall of the segment 300. This helps to better stabilize the posture of the box culvert 200 during assembly, thereby improving assembly efficiency and saving assembly time.

[0059] In some embodiments, reference Figure 3The support base 11 may include a first base body 111 and a second base body 112. The first base body 111 has a support surface adapted to fit against the inner wall of the tube segment 300. The first base body 111 may also define a ball head mounting cavity 1111, the inner wall of which is spherical and can open upwards. The second base body 112 has a second ball head 1123, which can extend into the ball head mounting cavity 1111 and rotate relative to the second base body 112. The second ball head 1123 is adapted to deflect within the ball head mounting cavity 1111. The bottom end of the lifting column 12 is connected to the second base body 112. In this way, the support seat 11 can adapt to the arc surface of the segment 300. When the second seat 112 is supported and engaged with different positions of the inner wall of the segment 300, the second seat 112 can adaptably rotate relative to the first seat 111, thereby keeping the lifting column 12 in a vertical state and stabilizing the posture of the box culvert 200.

[0060] In some embodiments, reference Figure 3 The second seat 112 may include a seat body 1121 and a connecting post 1122. The seat body 1121 is flat and has a slot with an opening along its thickness direction on the bottom wall. The connecting post 1122 is inserted into the slot and a second ball head 1123 is formed at the bottom end of the connecting post 1122. The bottom end of the lifting column 12 can be fixedly connected to the seat body 1121, such as by bolts. Thus, the structure of the second seat 112 is relatively simple.

[0061] In some embodiments, reference Figure 3 The support seat 11 may also include a pad 113, which is disposed on the support surface to support the first seat 111 when the first seat 111 is supported on the inner wall of the tube segment 300. In this way, the pad 113 can buffer the pressure of the support seat 11 on the tube segment 300 and prevent the tube segment 300 from being crushed.

[0062] In a specific example, the pad 113 can be a nylon pad 113. This provides good wear resistance, a long service life, and significant friction with the tube segment 300, ensuring the support seat 11 is fixed relative to the inner wall of the tube segment 300, thus facilitating better stability of the box culvert 200. However, this invention is not limited to this; the pad 113 can also be a rubber block or a pad 113 made of other materials.

[0063] In some embodiments, reference Figure 3The first base 111 has a mounting groove 1112 on its supporting surface. The bottom wall of the mounting groove 1112 has multiple first threaded connection holes. The depth of the mounting groove 1112 is less than the thickness of the pad 113. The pad 113 has multiple second threaded connection holes. The pad 113 is embedded in the mounting groove 1112 and protrudes from the supporting surface. The pad 113 and the first base 111 are connected by threaded fasteners that pass sequentially through the second threaded connection holes and the first threaded connection holes. Thus, when the first base 111 is inclined on the inner wall of the segment 300, it prevents the pad 113 from sliding relative to the supporting surface and ensures a stable connection between the pad 113 and the first base 111. This helps to further stabilize the orientation of the box culvert 200, allowing for better assembly of the box culvert 200.

[0064] In some embodiments, reference Figure 1 and Figure 2 The lifting column 12 may include a column body 121 and a lifting drive component 122. The column body 121 is movably mounted on the second seat 112. For example, the upper surface of the seat body 1121 of the second seat 112 may be provided with a guide post extending vertically. The column body 121 may be sleeved on the outside of the guide post, and the column body 121 may move up and down relative to the guide post. The lifting drive component 122 may be one of a hydraulic cylinder, an electric cylinder, or a pneumatic cylinder. The fixed end of the lifting drive component 122 may be hinged to the seat body 1121 of the second seat 112, and the piston end of the lifting drive component 122 may be hinged to the column body 121. Thus, the structure of the lifting column 12 is relatively simple and its operation is reliable.
