[0002] Reinforcing mesh, also known as welded reinforcing mesh, welded steel mesh, welded steel wire mesh, welded steel wire mesh sheet, etc., is a mesh sheet in which longitudinal and transverse reinforcing bars are arranged at certain intervals and at right angles to each other, and all intersections are welded together.

[0003] When supporting tunnels, according to the national standard "Specifications for Design of Highway Tunnels" JTGD70-2004, ribbed steel mesh should be installed inside the shotcrete. This is beneficial to improving the shear and bending strength of the shotcrete, enhancing its punching and bending resistance, improving the overall integrity of the shotcrete, reducing shrinkage cracks, preventing local spalling, and thus strengthening and protecting the tunnel.

[0004] In existing technologies, the installation of steel mesh in tunnels requires manual labor to move it to the installation point (the location on the tunnel wall) for fixation. This process is quite cumbersome, especially the installation of steel mesh at the tunnel ceiling, which is labor-intensive and inefficient, leading to a significant reduction in tunnel support efficiency. Therefore, inventing a device that can replace manual installation of steel mesh is a technical problem urgently needing to be solved by those skilled in the art. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0047] In the description of this utility model, it should be noted that, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and 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, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0048] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0049] In embodiments of this utility model, such as Figures 1 to 11 As shown, this circulating support device can be used for the installation of steel mesh, and includes a frame 1, a first telescopic rod 2, and a second telescopic rod 3; wherein,

[0050] A fixed shaft 11 is provided on the frame 1. The fixed ends of the first telescopic rod 2 and the second telescopic rod 3 are both rotatably mounted on the fixed shaft 11 around its axis. (See attached image) Figure 2 The first telescopic rod 2 is equipped with a first driving device 21 for driving the first telescopic rod 2 to rotate around the axis of the fixed shaft 11. The second telescopic rod 3 is equipped with a second driving device 31 for driving the second telescopic rod 3 to rotate around the axis of the fixed shaft 11. The telescopic end of the first telescopic rod 2 is equipped with multiple claws 22, and the telescopic end of the second telescopic rod 3 is equipped with a pressure plate 32. A slot 321 is opened on one side of the pressure plate 32. (See also...) Figure 1 .

[0051] When it is necessary to install the steel mesh, the staff can push the platform 1 to the working point of the steel mesh and make the axis of the fixed shaft 11 parallel to the extension direction of the tunnel. At this time, the staff can control the first drive device 21 to drive the first telescopic rod 2 to rotate around the axis of the fixed shaft 11.

[0052] When the first telescopic rod 2 rotates to the top of the steel mesh stack, specifically when the moving end of the first telescopic rod 2 moves between the fixed shaft 11 and the stack, the worker can control the first telescopic rod 2 to extend, that is, to move the moving end of the first telescopic rod 2 closer to the stack, until the claw 22 on the first telescopic rod 2 can contact the steel mesh at the stack and stop. At this time, the worker can control the claw 22 to grab the steel mesh at the stack, and after the claw 22 has firmly gripped it, the worker can control the first telescopic rod 2 to shorten and lift the steel mesh. Then, the worker can control the first drive device 21 to operate again to drive the first telescopic rod 2 to rotate around the axis of the fixed shaft 11 and send the steel mesh to the hanging point (the position where the steel mesh needs to be hung).

[0053] When the steel mesh is opposite to the hanging point, the workers can control the first telescopic rod 2 to extend, so that the steel mesh moves closer to the tunnel wall. The end of the exposed anchor rod on the tunnel wall will pass through the steel mesh and extend to the side of the steel mesh facing the circulating support device.

[0054] Subsequently, the staff can control the second drive device 31 to rotate the second telescopic rod 3 around the axis of the fixed shaft 11 to adjust the position of the pressure plate 32. When the pressure plate 32 is close to the hanging point, the staff can control the second telescopic rod 3 to extend so that the pressure plate 32 is close to the tunnel wall. At the same time, the staff can continue to drive the second telescopic rod 3 to rotate through the second drive device 31 so that the pressure plate 32 can squeeze and bend the anchor rod passing through the steel mesh to one side to form a hook-shaped structure during the movement, so that it can hook the steel mesh and complete the hanging of the steel mesh.

[0055] Next, the staff can control the claw 22 to release the hanging steel mesh and control the first telescopic rod 2 to retract. At the same time, control the first drive device 21 to move the moving end of the first telescopic rod 2 to the stacking area to grab the steel mesh.

[0056] After the anchor bolts at the installation points are bent, the workers can control the second telescopic rod 3 to retract, preventing the pressure plate 32 from bending the anchor bolts without steel mesh under the action of the second telescopic rod 3. By continuously and cyclically performing the above operation, the steel mesh can be installed quickly, thereby accelerating the tunnel support efficiency.

[0057] It should be noted that the pressure plate 32 is provided with a guide surface on the side facing away from the second telescopic rod 3. Under the guidance of the guide surface, the exposed anchor rod can be bent to one side to form a hook-shaped structure to fix the steel mesh.

[0058] Furthermore, when the anchor rod is squeezed by the pressure plate 32, the length of the first telescopic rod 2 is 3-5cm longer than the length of the second telescopic rod 3, so that the squeezed anchor rod has enough length to bend and form a hook-shaped structure.

[0059] In this embodiment, the area of ​​the pressure plate 32 is equal to the area of ​​the steel mesh, and when the pressure plate 32 approaches the position of the first telescopic rod 2, the slot 321 on the pressure plate 32 can accommodate the part of the first telescopic rod 2 near its telescopic end, so that the pressure plate 32 can completely overlap with the projection surface of the steel mesh at the hanging point, so that the pressure plate 32 can bend all the anchor rods passing through the steel mesh, thereby fixing the steel mesh.

[0060] Furthermore, when the side wall of the first telescopic rod 2 is in contact with the bottom of the slot 321, the telescopic direction of the first telescopic rod 2 is parallel to the telescopic direction of the second telescopic rod 3, and the orientation of the telescopic end of the first telescopic rod 2 is the same as the orientation of the telescopic end of the second telescopic rod.

[0061] Both the first drive device 21 and the second drive device 31 mentioned above are rotary motors.

[0062] Preferably, the guide surface is inclined from one side of the slot opening of the slot 321 toward the bottom of the slot 321 in a direction away from the second telescopic rod 3;

[0063] When the second telescopic rod 3 rotates, the side of the pressure plate 32 corresponding to the slot 321 first enters the area of ​​the hanging point until the pressure plate 32 and the projection surface of the steel mesh are completely overlapped, so that the pressure plate 32 can more easily bend the anchor rod passing through the steel mesh when passing through the area of ​​the hanging point, so as to fix the steel mesh.

[0064] In some embodiments, the fixed end of the first telescopic rod 2 described above is provided with a first connecting ring 23, see [reference]. Figure 6 and Figure 7 The inner diameter of the first connecting ring 23 matches the diameter of the fixed shaft 11. The inner side wall of the first connecting ring 23 is provided with a first receiving groove 231. The first telescopic rod 2 is rotatably mounted on the fixed shaft 11 through the first connecting ring 23.

[0065] The outer side wall of the first connecting ring 23 is provided with a first through hole 232 communicating with the first receiving groove 231, the actuating end of the first driving device 21 extends to the first through hole 232, and the actuating end of the first driving device 21 is provided with a first driving gear 211.

[0066] A first external gear ring 111 is coaxially disposed on the fixed shaft 11 and meshes with the first drive gear 211. The first external gear ring 111 is located in the first receiving groove 231. In this embodiment, the width of the first external gear ring 111 matches the width of the first receiving groove 231 to fix the position of the first connecting ring 23 and prevent the first connecting ring 23 from moving along the axial direction of the fixed shaft 11.

[0067] The first drive gear 211 passes through the first through hole 232 and meshes with the first external gear ring 111. The first drive device 21 drives the first drive gear 211 to rotate, which can control the position change of the first telescopic rod 2.

[0068] In some embodiments, the fixed end of the second telescopic rod 3 described above is provided with a second connecting ring 33, see [link to previous document]. Figure 8 and Figure 9 The inner diameter of the second connecting ring 33 matches the diameter of the fixed shaft 11. The inner side wall of the second connecting ring 33 is provided with a second receiving groove 331. The second telescopic rod 3 is rotatably mounted on the fixed shaft 11 through the second connecting ring 33.

[0069] The outer side wall of the second connecting ring 33 is provided with a second through hole 332 communicating with the second receiving groove 331. The actuating end of the second driving device 31 extends to the second through hole 332, and the actuating end of the second driving device 31 is provided with a second driving gear 312.

[0070] A second external gear ring 112 is coaxially disposed on the fixed shaft 11 and meshes with the second drive gear 312. The second external gear ring 112 is located in the second receiving groove 331. In this embodiment, the width of the second external gear ring 112 matches the width of the second receiving groove 331 to fix the position of the second connecting ring 33 and prevent the second connecting ring 33 from moving along the axial direction of the fixed shaft 11.

[0071] The second drive gear 312 passes through the second through hole 332 and meshes with the second external gear ring 112. The second drive device 31 drives the second drive gear 312 to rotate, which can control the position change of the second telescopic rod 3.

[0072] In some embodiments, the aforementioned platform 1 includes a frame 12 and casters 13, see [link to previous document]. Figure 1 and Figure 4 ;in,

[0073] There are multiple rollers 13, and all rollers 13 are located at the bottom of the frame 12 to make it easier to move the frame 12.

[0074] The aforementioned fixed shaft 11 is mounted on the frame 12. Preferably, a drive motor can also be mounted on the frame 12, with the actuating end of the drive motor connected to the roller 13. By controlling the start and stop of the drive motor, the frame 12 can be moved and stopped, making the movement of the platform 1 more convenient.

[0075] In some embodiments, the rollers 13 described above include a traveling wheel and a swivel wheel. Both the traveling wheel and the swivel wheel can support the movement of the frame 12, and the swivel wheel can enable the platform 1 to turn, so as to facilitate the movement and turning of the platform 1.

[0076] In some embodiments, the frame 12 described above is provided with a lifting rail 14, see [reference]. Figure 3 and Figure 4 ;

[0077] The length direction of the lifting track 14 is perpendicular to the horizontal plane, and a rack A141 is provided on the lifting track 14. The length direction of the rack A141 is parallel to the length direction of the lifting track 14.

[0078] A first sliding seat 143 capable of sliding along the length of the lifting track 14 is sleeved on the lifting track 14. A vertical drive motor 142 is provided on the first sliding seat 143. The actuating end of the vertical drive motor 142 is provided with a drive gear A that cooperates with the rack A141.

[0079] The fixed shaft 11 is mounted on the first sliding seat 143. By controlling the vertical drive motor 142, the position of the first sliding seat 143 on the lifting track 14 can be adjusted to adjust the height of the fixed shaft 11. This makes it more convenient for the circulating support device to grab steel mesh and hang steel mesh on the top of the tunnel. It also makes the circulating support device suitable for hanging steel mesh in tunnels of various heights.

[0080] In some embodiments, the first sliding seat 143 described above is provided with a transverse track 15, see [link / reference] Figure 4 and Figure 5 ;

[0081] The length direction of the transverse track 15 is perpendicular to the length direction of the lifting track 14 and the axis of the fixed shaft 11. A rack B151 is provided on the transverse track 15, and the length direction of the rack B151 is parallel to the length direction of the transverse track 15. A second sliding seat 153 that can slide along the length direction of the transverse track 15 is sleeved on the transverse track 15. A transverse drive motor 152 is provided on the second sliding seat 153, and the actuating end of the transverse drive motor 152 is provided with a drive gear B that cooperates with the rack B151.

[0082] The fixed shaft 11 is mounted on the second sliding seat 153. By controlling the action of the transverse drive motor 152, the position of the second sliding seat 153 on the transverse track 15 can be adjusted to adjust the distance between the fixed shaft 11 and the tunnel sidewall. This makes it more convenient for the circulating support device to hang the steel mesh on the tunnel sidewall and also enables the circulating support device to be applicable to the hanging of steel mesh in tunnels of various widths.

[0083] Preferably, the number of the above-mentioned lifting rails 14 is four, and the four lifting rails 14 are arranged around the circumference of the frame 12;

[0084] There are two transverse tracks 15. The two ends of one transverse track 15 are slidably mounted on two adjacent lifting tracks 14 via the second sliding seat 153. The two ends of the other transverse track 15 are slidably mounted on two other adjacent lifting tracks 14 via the second sliding seat 153, so that the lifting of the transverse track 15 is more stable.

[0085] Furthermore, the two transverse tracks 15 are parallel, and the two ends of the fixed shaft 11 are respectively set on the second sliding seats 153 of the two transverse tracks 15, so that the workers can adjust the fixed shaft 11, that is, adjust the position of the first telescopic rod 2 and the second telescopic rod 3 more smoothly.

[0086] To further improve the safety of the circulating support device when transferring steel mesh, a fitting plate is provided at the telescopic end of the first telescopic rod 2, and multiple claws 22 are set on the fitting plate. The fitting plate restricts the position of the steel mesh to prevent the steel mesh on the claws 22 from falling down through the first telescopic rod 2 under the action of gravity when the first telescopic rod 2 sends the steel mesh to the top of the tunnel.

[0087] In some embodiments, the claw 22 described above includes a fixing part 221, a clamping part 222, and a telescopic motor 223. The fixing part 221 is fixedly disposed on the side of the bonding plate opposite to the first telescopic rod 2. One end of the clamping part 222 is hinged to the side of the bonding plate opposite to the first telescopic rod 2. The telescopic motor 223 is disposed on the first telescopic rod 2. The actuating end of the telescopic motor 223 passes through the bonding plate and is hinged to the middle of the clamping part 222.

[0088] When the actuating end of the telescopic motor 223 retracts, it pulls the clamping part 222, causing the end of the clamping part 222 away from the adhesive plate to be tightly pressed against the fixing part 221, thereby achieving clamping and fixing of the steel mesh. See [link to documentation]. Figure 10 ;

[0089] When the actuating end of the telescopic motor 223 extends, it pushes the clamping part 222, causing the end of the clamping part 222 away from the adhesive plate to separate from the fixing part 221, thus releasing the steel mesh. (See [link]) Figure 11 .

[0090] Preferably, the end of the clamping part 222 away from the bonding plate is configured as a hook-shaped structure so that the claw 22 can prevent the steel mesh from falling off when gripping the steel mesh, thereby improving the safety of the circulating support device during use.

[0091] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
