Description

Technical Field

[0001] This utility model belongs to the technical field of steel mesh installation equipment, and specifically relates to a circulating steel mesh installation device. Background Technology

[0002] Currently, tunnel design both domestically and internationally is mainly based on the New Austrian Tunneling Method (NATM) support concept. This involves constructing the tunnel body after excavation by forming a composite inner and outer lining. The outer support consists of shotcrete, rock bolts, steel mesh, and steel supports, and is referred to as the initial flexible support. Among these, steel mesh plays a crucial role in strengthening the initial support, controlling surrounding rock deformation in conjunction with rock bolts, and increasing the toughness of the initial support.

[0003] With the development of tunnel mechanization, wet spraying robots are now widely used for shotcreting, and anchor bolts are gradually being installed using integrated anchor bolt drilling and injection machines. However, there is currently no effective dedicated construction equipment for the installation of steel mesh, which is mostly done manually on a platform. The efficiency of manual installation of steel mesh is low and the workload is large, which slows down the construction progress of the tunnel. Therefore, inventing a device that can replace manual installation of steel mesh is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] This invention provides a circulating steel mesh installation device to solve the technical problem that the low efficiency of manual installation of steel mesh in the prior art leads to a slowdown in tunnel construction progress.

[0005] This utility model is achieved through the following technical solution:

[0006] A circulating steel mesh installation device includes a frame and a controller;

[0007] The frame is equipped with a rotating shaft and a rotary drive motor. The rotation axis of the rotating shaft is parallel to the horizontal plane, and the actuating end of the rotary drive motor is connected to the rotating shaft. A telescopic rod is provided on the side wall of the rotating shaft. The direction of movement of the telescopic rod is perpendicular to the rotation axis of the rotating shaft. The actuating end of the telescopic rod is equipped with multiple claws for gripping the steel mesh.

[0008] The controller is connected to the telescopic boom, the rotary drive motor, and the chucks via signal connection, and is used to control the movement of the telescopic boom, the rotary drive motor, and the chucks.

[0009] To better realize this utility model, the above structure is further optimized, and the platform includes a frame and pulleys;

[0010] There are multiple pulleys, all of which are located at the bottom of the frame.

[0011] Both the rotating shaft and the rotary drive motor are mounted on the frame.

[0012] To better realize this utility model, the above structure is further optimized, and the pulley includes a traveling wheel and a swivel wheel.

[0013] To better realize this utility model, the above structure is further optimized by providing a lifting track on the frame.

[0014] The length direction of the lifting track is perpendicular to the horizontal plane. A rack A is installed on the lifting track, and the length direction of rack A is parallel to the length direction of the lifting track. A first sliding seat that can slide along the length direction of the lifting track is fitted on the lifting track. A vertical drive motor is installed on the first sliding seat. The actuating end of the vertical drive motor is equipped with a drive gear A that cooperates with rack A. The controller is connected to the vertical drive motor for signal control of the vertical drive motor.

[0015] Both the rotating shaft and the rotary drive motor are mounted on the first sliding seat.

[0016] To better realize this utility model, further optimizations are made to the above structure. A transverse track is provided on the first sliding seat. The length direction of the transverse track is perpendicular to the length direction of the lifting track and the rotation axis of the rotating shaft. A rack B is provided on the transverse track. The length direction of the rack B is parallel to the length direction of the transverse track. A second sliding seat that can slide along the length direction of the transverse track is sleeved on the transverse track. A transverse drive motor is provided on the second sliding seat. The actuating end of the transverse drive motor is provided with a drive gear B that cooperates with the rack B. The controller is signal-connected to the transverse drive motor and is used to control the operation of the transverse drive motor.

[0017] Both the rotating shaft and the rotary drive motor are mounted on the second sliding seat.

[0018] To better realize this utility model, the above structure is further optimized, and the number of lifting rails is four, which are arranged around the circumference of the frame.

[0019] The number of transverse tracks is two. The two ends of one transverse track are slidably mounted on two adjacent lifting tracks via second sliding seats. The two ends of the other transverse track are slidably mounted on two other adjacent lifting tracks via second sliding seats. The two transverse tracks are parallel.

[0020] The two ends of the rotating shaft are respectively rotatably mounted on the second sliding seats of the two transverse tracks.

[0021] To better realize this utility model, the above structure is further optimized by providing a bearing seat on the second sliding seat, and the rotating shaft is rotatably mounted on the second sliding seat through the bearing seat.

One end of the clamping part is hinged to the side of the bonding plate away from the telescopic rod. The telescopic motor is disposed on the telescopic rod. The actuating end of the telescopic motor passes through the bonding plate and is hinged to the middle of the clamping part. The controller is signal-connected to the telescopic motor and is used to control the operation of the telescopic motor. When the actuating end of the telescopic motor retracts, it can pull the clamping part, so that the end of the clamping part away from the bonding plate is tightly attached to the fixing part.

[0025] Compared with the prior art, this utility model has the following advantages:

[0026] The controller in the cyclic rebar mesh installation device provided by this utility model can control the telescopic rod, the rotary drive motor, and the jaws. By rotating the drive motor, the position of the telescopic rod is adjusted so that it can stop at the accumulation point and the attachment point of the rebar mesh. The movement of the telescopic rod adjusts the distance between the jaws and the accumulated rebar mesh, as well as the distance between the gripped rebar mesh and the attachment point, so as to facilitate the gripping and releasing of the rebar mesh and complete the rapid installation of the rebar mesh. Repeating the above operation realizes the cyclic installation of the rebar mesh, improves the installation efficiency of the rebar mesh, and thus speeds up the tunnel construction progress.

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.

Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0044] 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.

[0045] In the embodiments of this application, such as Figures 1 to 8 As shown, the circulating steel mesh installation device includes a frame 1 and a controller (not shown in the figure). In this embodiment, the controller is a PLC controller; wherein,

[0046] A rotating shaft 2 and a rotary drive motor 3 are mounted on the frame 1. The rotation axis of the rotating shaft 2 is parallel to the horizontal plane, and the actuating end of the rotary drive motor 3 is connected to the rotating shaft 2 for transmission. A telescopic rod 4 is mounted on the side wall of the rotating shaft 2. (See attached image) Figure 5 The telescopic rod 4 moves in a direction perpendicular to the rotation axis of the rotating shaft 2. The moving end of the telescopic rod 4 is equipped with multiple claws 5 for gripping the steel mesh.

[0047] The controller is connected to the telescopic rod 4, the rotary drive motor 3, and the gripper 5 via signal connection. It is used to control the movement of the telescopic rod 4, the rotary drive motor 3, and the gripper 5. Specifically, it controls the telescopic rod 4 to stop or extend, controls the rotary drive motor 3 to start, stop, and adjust its rotation direction, and controls the gripper 5 to grab or release.

[0048] When it is necessary to lay the steel mesh, the staff can push the platform 1 to the work point of the steel mesh. At this time, the axis of the aforementioned rotating shaft 2 is parallel to the extension direction of the tunnel. The staff can then control the rotary drive motor 3 to move through the controller. The rotary drive motor 3 will drive the rotating shaft 2 to rotate, and the telescopic rod 4 on the rotating shaft 2 will also rotate with the rotating shaft 2.

[0049] When the telescopic rod 4 moves above the pile of steel mesh, specifically when the telescopic rod 4 moves between the rotating shaft 2 and the pile, the staff can control the telescopic rod 4 to extend through the controller, that is, to move the moving end of the telescopic rod 4 toward the pile until the claw 5 of the moving end of the telescopic rod 4 contacts the steel mesh at the pile and stops.

[0050] Workers can then use the controller to control the claw 5 to grab the steel mesh from the pile, and use the controller to control the rotary drive motor 3 to continue working, so that the telescopic rod 4, as it rotates with the rotating shaft 2, delivers the steel mesh to the patching point (the location where the steel mesh needs to be installed) for hanging. When the steel mesh is hung on the tunnel wall, workers can use the controller to control the claw 5 to release the steel mesh, thus completing one steel mesh installation process.

[0051] Repeat the above operation. Whenever the telescopic rod 4 moves between the rotating shaft 2 and the stacking area, the workers can control the telescopic rod 4 to extend through the controller and control the claw 5 to grab the steel mesh at the stacking area. Then, the rotating shaft 2 is driven by the rotary drive motor 3 to move, so that the telescopic rod 4, as it rotates with the rotating shaft 2, delivers the steel mesh to the mounting area for installation. By repeating this operation, the steel mesh can be installed quickly, thereby speeding up the tunnel construction progress.

[0052] It should be noted that during tunnel construction, workers will insert anchor rods into the tunnel wall and bend the ends of the anchor rods to form hook-shaped structures. When the telescopic rod 4 rotates with the rotating shaft 2 to deliver the steel mesh to the patch, the steel mesh can be easily hung on the end of the anchor rod to complete the installation of the steel mesh.

[0053] This circulating steel mesh installation device can effectively reduce the labor involved in steel mesh installation and accelerate the installation efficiency, thereby improving the construction efficiency of tunnels.

[0054] To further improve the safety of the circulating steel mesh installation device during the transfer of steel mesh, a fitting plate 41 is provided at the moving end of the telescopic rod 4, and multiple claws 5 are set on the fitting plate 41. The fitting plate 41 restricts the position of the steel mesh to prevent the steel mesh on the claws 5 from falling down through the telescopic rod 4 under the action of gravity when the telescopic rod 4 sends the steel mesh to the top of the tunnel.

[0055] In some embodiments, the aforementioned claw 5 includes a fixing part, a clamping part, and a telescopic motor 51, see [link to documentation]. Figure 7 and Figure 8The fixing part is fixedly installed on the side of the bonding plate 41 away from the telescopic rod 4. One end of the clamping part is hinged to the side of the bonding plate 41 away from the telescopic rod 4. The telescopic motor 51 is installed on the telescopic rod 4. The actuating end of the telescopic motor 51 passes through the bonding plate 41 and is hinged to the middle of the clamping part. The controller is signal connected to the telescopic motor 51 and is used to control the telescopic movement of the telescopic motor 51.

[0056] When the actuating end of the telescopic motor 51 retracts, it pulls the clamping part, causing the end of the clamping part away from the bonding plate 41 to be tightly pressed against the fixing part, thereby achieving clamping and fixing of the steel mesh. See [link to documentation]. Figure 7 ;

[0057] When the actuating end of the telescopic motor 51 extends, it pushes the clamping part, causing the end of the clamping part away from the adhesive plate 41 to separate from the fixed part, thus releasing the steel mesh. See [link to relevant documentation]. Figure 8 .

[0058] Preferably, the end of the clamping part away from the bonding plate 41 is configured as a hook structure so that the claw 5 can prevent the steel mesh from falling off when gripping the steel mesh, thereby improving the safety of the circulating steel mesh installation device during use.

[0059] In some embodiments, the number of the aforementioned telescopic rods 4 is multiple, and the multiple telescopic rods 4 are equally spaced around the circumference of the rotating shaft 2 to further improve the installation efficiency of the steel mesh.

[0060] In some embodiments, the aforementioned platform 1 includes a frame 11 and casters 12, see [link / reference]. Figure 1 and Figure 4 ;

[0061] There are multiple pulleys 12, and all pulleys 12 are set at the bottom of the frame 11 to make the movement of the frame 11 more convenient;

[0062] Both the rotating shaft 2 and the rotary drive motor 3 are mounted on the frame 11. Preferably, an engine can also be mounted on the frame 11. The engine's actuating end is connected to the pulley 12 for transmission, and the engine is connected to the controller for signal transmission. The controller can control the engine's start-up, shutdown, and rotation direction adjustment to make the movement of the platform 1 more convenient.

[0063] In some embodiments, the pulley 12 includes a traveling wheel and a swivel wheel. Both the traveling wheel and the swivel wheel can support the movement of the frame 11, and the swivel wheel can enable the platform 1 to turn, so as to facilitate the movement and turning of the platform 1.

[0064] In some embodiments, the frame 11 described above is provided with a lifting rail 13, see [reference]. Figure 3 and Figure 4 ;

[0065] The length direction of the lifting track 13 is perpendicular to the horizontal plane, and a rack A131 is provided on the lifting track 13. The length direction of the rack A131 is parallel to the length direction of the lifting track 13.

[0066] A first sliding seat 133 capable of sliding along the length of the lifting track 13 is fitted on the lifting track 13. A vertical drive motor 132 is provided on the first sliding seat 133. The actuating end of the vertical drive motor 132 is provided with a drive gear A that cooperates with the rack A131. The controller is signal-connected to the vertical drive motor 132 and is used to control the action of the vertical drive motor 132, including starting, stopping and adjusting the rotation direction of the vertical drive motor 132.

[0067] Both the rotating shaft 2 and the rotary drive motor 3 are mounted on the first sliding seat 133;

[0068] By controlling the vertical drive motor 132 to operate, the position of the first sliding seat 133 on the lifting track 13 can be adjusted to adjust the height of the rotating shaft 2. This makes it more convenient for the circulating steel mesh installation device to grab steel mesh and install steel mesh on the top of the tunnel. It also makes the circulating steel mesh installation device applicable to the installation of steel mesh in tunnels of various heights.

[0069] In some embodiments, the first sliding seat 133 described above is provided with a transverse track 14, see [link to previous document]. Figure 4 and Figure 6 The length direction of the transverse track 14 is perpendicular to the length direction of the lifting track 13 and the rotation axis of the rotating shaft 2. A rack B141 is provided on the transverse track 14, and the length direction of the rack B141 is parallel to the length direction of the transverse track 14.

[0070] A second sliding seat 143, which can slide along the length direction of the transverse track 14, is sleeved on the transverse track 14. A transverse drive motor 142 is provided on the second sliding seat 143. The actuating end of the transverse drive motor 142 is provided with a drive gear B that cooperates with the rack B141. The controller is connected to the transverse drive motor 142 by signal and is used to control the action of the transverse drive motor 142, including starting, stopping and adjusting the rotation direction of the transverse drive motor 142.

[0071] Both the rotating shaft 2 and the rotary drive motor 3 are mounted on the second sliding seat 143.

[0072] By controlling the transverse drive motor 142 to operate, the position of the second sliding seat 143 on the transverse track 14 can be adjusted to adjust the distance between the rotating shaft 2 and the tunnel sidewall. This makes it more convenient to install the steel mesh on the tunnel sidewall using the circulating steel mesh installation device, and also makes the circulating steel mesh installation device applicable to the installation of steel mesh in tunnels of various widths.

[0073] Preferably, the number of lifting tracks 13 is four, see [reference]. Figure 1 and Figure 4 Four lifting tracks 13 are arranged circumferentially around the frame 11;

[0074] There are two transverse tracks 14. The two ends of one transverse track 14 are slidably mounted on two adjacent lifting tracks 13 via the second sliding seat 143. The two ends of the other transverse track 14 are slidably mounted on two other adjacent lifting tracks 13 via the second sliding seat 143, so that the lifting of the transverse track 14 is more stable.

[0075] Furthermore, the two transverse tracks 14 are parallel, and the two ends of the rotating shaft 2 are respectively rotatably set on the second sliding seats 143 of the two transverse tracks 14, so that the workers can adjust the position of the rotating shaft 2, that is, adjust the position of the telescopic rod 4, more smoothly.

[0076] In some embodiments, a bearing seat 15 is provided on the second sliding seat 143, see [reference] Figure 2 and Figure 4 The rotating shaft 2 is rotatably mounted on the second sliding seat 143 via the bearing seat 15, so that the rotation of the rotating shaft 2 is smoother.

[0077] 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.
