Technical Field

[0001] This invention relates to the field of netting technology for crossing frames, and more specifically to a netting system and method for crossing frames. Background Technology

[0002] Crossing frame enclosure is a core safety technology in the construction of power transmission lines. Its goal is to construct a temporary but absolutely reliable aerial barrier when new lines are laying conductors and ground wires across existing facilities (such as live lines, highways, railways, rivers, etc.) to ensure that the conductors can be caught in the event of an accidental fall or breakage, thereby protecting the safety of facilities and personnel below.

[0003] In existing technologies, ground-mounted double-rocker arm poles are often used as the main structure of the crossing frame, with the double rocker arms extending laterally and multiple points of manual assistance for netting installation. However, this type of ground-mounted double-rocker arm pole crossing frame is complex to construct, and manual netting installation is inconvenient and poses safety hazards, resulting in low netting efficiency and poor safety.

A lifting assembly is disposed at the inner bottom of the housing. The output end of the lifting assembly is connected to the drive assembly and is used to drive the drive assembly to lift and lower, thereby causing the two sets of anti-slip wheels to abut or disengage from the side wall of the supporting rope.

[0010] Optionally, the driving component includes: Two sets of first support plates are symmetrically arranged at both ends of the two sets of anti-slip wheels. The two ends of each set of first support plates are respectively sleeved on the same end of the two sets of anti-slip wheels and rotatably connected.

Simultaneously, multiple sets of traction devices are connected to the other end of the corresponding hanging net frame. When the traction device moves along the corresponding support rope from one set of crossbeams to another, it can pull the corresponding hanging net frame to extend and drive the net rope below to form the net. When the traction device moves to another set of crossbeams, it can be locked and fixed with the corresponding locking device to achieve stable netting. Conversely, when the traction device needs to move along the corresponding support rope from another set of crossbeams to one set of crossbeams, the corresponding locking device is opened, causing the traction device to disengage, pulling the corresponding hanging net frame to fold back to its original position, and simultaneously folding and storing the net rope below, thus achieving the purpose of netting disassembly. Using the above structure, the efficiency and convenience of netting can be effectively improved, making it more intelligent and reliable, while also ensuring the safety of the netting.

[0018] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of the present invention.

[0019] Figure 1 This is a schematic diagram of the structure of a mesh enclosure system for a crossing frame according to an embodiment of the present invention. Figure 2 This is a schematic diagram of the structure of the blocking block and the L-shaped plate abutting and cooperating in the sealing system of the scaffolding according to an embodiment of the present invention. Figure 1 and Figure 2 As shown, the netting system may include two sets of crossbeams 40, multiple sets of net rope storage devices, multiple sets of traction devices, multiple sets of locking devices, and multiple sets of supporting ropes 30. Specifically, the net rope storage device may include a net hanging frame 34, which may include net ropes.

[0020] Two sets of crossbeams 40 are respectively set at both ends of the span frame. Multiple sets of net rope storage devices are equally spaced on one set of crossbeams 40. One end of each net rope storage device is equipped with a foldable and extendable hanging net frame 34, and net ropes are evenly hung below the hanging net frame 34. Multiple sets of traction devices are respectively connected to the other end of the corresponding hanging net frame 34. Multiple sets of locking devices are equally spaced on the other set of crossbeams 40 for locking in conjunction with the corresponding traction devices. Multiple sets of supporting ropes 30 are respectively threaded along the corresponding net rope storage device, traction device, and locking device for cooperating with the corresponding traction device to extend or fold the corresponding hanging net frame 34.

[0021] In a preferred embodiment of the present invention, considering the difficulty of assembling a ground-mounted double-arm gantry crane, which consumes a significant amount of time and cost, the present invention employs two sets of cranes as the main bodies at both ends of the gantry frame, effectively reducing the difficulty of assembling the gantry frame and improving efficiency. Two sets of crossbeams 40 are respectively installed at the top / output ends of the two sets of cranes. Multiple sets of supporting ropes 30 are then threaded along the corresponding net rope storage device, traction device, and locking device to connect the corresponding crossbeams 40 of the two sets of cranes. Simultaneously, multiple sets of traction devices are activated to move along the corresponding supporting ropes 30, from the net rope storage device to the corresponding locking device, and are locked in place. During the movement of the traction devices, the hanging net frame 34 gradually extends, effectively sealing the net. When it is necessary to disassemble the sealed state, the locking device is controlled to disengage from the locking state of the traction device, and the traction device moves in the opposite direction along the corresponding supporting rope 30, from the locking device to the corresponding net rope storage device. At this point, the hanging net frame 34 and the net rope are gradually folded and stored through the net rope storage device, which facilitates the subsequent disassembly of the device.

[0022] Traditional cross-pass netting systems often employ ground-mounted double-rocker arm poles as the main structure, with the double rocker arms extending laterally and the netting being laid manually at multiple points. However, this type of ground-mounted double-rocker arm pole cross-pass frame is complex to assemble, and manual netting is inconvenient and poses safety hazards, resulting in low netting efficiency and poor safety. In this embodiment of the invention, a traction device is used to move along the supporting rope 30 and, in conjunction with the net rope storage device, extend or fold the hanging net frame 34 and the net rope. This effectively improves the efficiency and convenience of netting, making it more intelligent and reliable, while also ensuring the safety of the netting. Furthermore, the use of a locking device to lock the traction device ensures the stability and reliability of the netting state.

[0023] In this embodiment of the invention, such as Figures 2 to 4 As shown, the net rope storage device may include a first support base 28, a first pulley 29, and a hinge assembly.

[0024] The first support base 28 is mounted on one of the sets of crossbeams 40, and the first pulley 29 is rotatably mounted on the first support base 28. The supporting rope 30 is wound around the first pulley 29. The hinge assembly is mounted at one end of the first support base 28, and the traction device and the hanging net frame 34 are mounted on the top of the corresponding hinge assembly. The hinge assembly is used to cooperate with the traction device to lock or unlock the hanging net frame 34.

[0025] The first support base 28 is fixedly installed on the corresponding crossbeam 40, and the first pulley 29 is inclined to facilitate the winding and guiding of the supporting rope 30. The hinge assembly is parallelogram-shaped in the unlocked state and square-shaped in the locked state. Specifically, the traction device can cooperate with the hinge assembly to convert the hinge assembly from a parallelogram to a square shape, raising the hanging frame 34 and separating it from the supporting rope 30 to lock the hanging frame 34. Conversely, under the action of gravity, the hinge assembly converts from a square shape to a parallelogram shape, releasing the hanging frame 34 from the supporting rope 30, allowing the traction device to pull the hanging frame 34 along the supporting rope 30, thus unlocking the hanging frame 34.

[0026] In this embodiment of the invention, such as Figures 2 to 4 As shown, the hinge assembly may include a first support frame 31, two sets of hinge rods 32, a second support frame 33, and a third support frame.

[0027] One end of the first support frame 31 is connected to one end of the first support base 28. Two sets of hinge rods 32 are distributed in parallel, and the bottom ends of the two sets of hinge rods 32 are respectively hinged to both ends of the first support frame 31. The two ends of the second support frame 33 are respectively hinged to the two sets of hinge rods 32. The hanging net frame 34 is set on the top of the second support frame 33. Specifically, one end of the hanging net frame 34 is connected to the second support frame 33, and the other end is connected to the housing 1. The third support frame is set at the end of the second support frame 33 away from the first support base 28, and slides in cooperation with the corresponding traction device. Specifically, the third support frame has a groove on the inner wall corresponding to the side wall / side plate 4 of the housing 1, and the stop block 39 is set on the inner wall of the groove.

[0028] When the hanging frame 34 needs to be stored / locked, the traction device, in conjunction with the stop 39 on the inner wall of the third support frame, acts on the two sets of hinge rods 32, causing the hinge assembly to change from a parallelogram to a square shape. One end of the second support frame 33 and the hanging frame 34 then abuts against the first support base 28, while the traction device locks the other end of the second support frame 33 and the hanging frame 34. Conversely, when the traction device and the stop 39 are no longer engaged, the traction device and the third support frame, under the influence of gravity, cause the hinge assembly to change direction back to a parallelogram, thus unlocking the hanging frame 34 and facilitating subsequent synchronous movement with the traction device.

[0029] In this embodiment of the invention, such as Figures 5 to 15 As shown, the traction device may include a housing 1, a moving component, and a storage component. Specifically, the housing 1 may include two sets of threading holes 2.

[0030] The housing 1 is mounted on the third support frame. Each end of the housing 1 has a threading hole 2 for threading a supporting rope 30. One end of the housing 1 is connected to the hanging net frame 34. A moving component is located inside the housing 1 and abuts against the outside of the supporting rope 30, driving the housing 1 to move along the extension direction of the supporting rope 30. Storage components are symmetrically arranged on both sides of the moving component, driving the housing 1 to push the hanging net frame 34 to fold and store it.

[0031] A foldable hanging net frame 34 is installed on the second support frame 33. Net ropes are hung at the bottom of the hanging net frame 34. A supporting rope 30 is then passed through the hanging net frame 34 and the threaded hole 2 on the housing 1. With the help of a drone, the supporting rope 30 is passed through and fixed to the locking device to stably connect the crossbeams 40 of the two cranes. When it is necessary to install netting over a road or railway, the moving component is activated, causing it to abut against the side wall of the supporting rope 30 and drive the housing 1 to move along the extension direction of the supporting rope 30, i.e., towards one end of the locking device. Since one end of the housing 1 is connected to the hanging net frame 34, it can extend the hanging net frame 34 and the net rope below it. When the housing 1 moves to the locking device, it locks in place, achieving reliable netting over the road or railway. When it is necessary to release the netting, the housing 1 is disengaged from the locking device, and the moving component is activated to drive the housing 1 to move in the opposite direction until it returns to its original position on the third support frame. At this time, the hanging frame 34 moves and folds synchronously, thereby causing the net rope to fold. After the housing 1 is reset, the storage component can be activated so that the housing 1 pushes the hanging frame 34 to further fold and store / lock the hanging frame 34.

[0032] In this embodiment of the invention, the housing 1 may include two sets of side plates 4, which can be understood as two opposite side wall plates perpendicular to the moving direction of the housing 1. The wire hole 2 is located on the two end plates of the housing 1 along the moving direction of the housing 1.

[0033] In this embodiment of the invention, such as Figures 11 to 15 As shown, the moving component may include two sets of anti-slip wheels 19, a drive component, and a lifting component.

[0034] Two sets of anti-slip wheels 19 are distributed along the extension direction of the support rope 30. The output end of the drive component is connected to the two sets of anti-slip wheels 19 to drive the two sets of anti-slip wheels 19 to rotate synchronously. The lifting component is located at the inner bottom of the housing 1. The output end of the lifting component is connected to the drive component to drive the drive component to lift and lower, so that the two sets of anti-slip wheels 19 abut against or disengage from the side wall of the support rope 30.

[0035] When the housing 1 needs to move along the support rope 30, the lifting component is activated to raise the driving component. Since the driving component is connected to two sets of anti-slip wheels 19, it can synchronously drive the two sets of anti-slip wheels 19 to rise, so that the two sets of anti-slip wheels 19 gradually contact and abut against the side wall of the support rope 30. After the two sets of anti-slip wheels 19 abut against the side wall of the support rope 30, that is, after friction is generated, the driving component is activated. The driving component drives the two sets of anti-slip wheels 19 to rotate synchronously, and moves on the support rope 30 in conjunction with the friction with the support rope 30, thereby moving the housing 1 and the storage component from one set of crossbeams 40 of the crossing frame to another set of crossbeams 40, realizing the extension and laying of the net frame 34 and the net rope. Conversely, the driving component can drive the two sets of anti-slip wheels 19 to rotate in the opposite direction, so as to move the housing 1 and the storage component from another set of crossbeams 40 of the crossing frame to one set of crossbeams 40, realizing the folding and storage of the net frame 34 and the net rope. By using a lifting component and a drive component to lift the two sets of anti-slip wheels 19, the two sets of anti-slip wheels 19 can achieve stable contact and discontinuation with the support rope 30, which facilitates movement and disengagement control, and improves the convenience and flexibility of control.

[0036] In this embodiment of the invention, the housing 1 may also include two sets of rotating wheels rotatably disposed at the top of the housing 1. These two sets of rotating wheels cooperate with the two sets of anti-slip wheels 19 after being raised to abut against the supporting rope 30.

[0037] In this embodiment of the invention, such as Figures 11 to 15 As shown, the drive assembly may include two sets of first support plates 23, second support plates 21, drive motor 20, first transmission assembly 15 and second transmission assembly 22.

[0038] Two sets of first support plates 23 are symmetrically arranged at both ends of the two sets of anti-slip wheels 19. Each set of first support plates 23 has its ends respectively fitted onto the same end of the two sets of anti-slip wheels 19 and are rotatably connected. A second support plate 21 is located on the side of one set of first support plates 23 away from the other set of first support plates 23, and a drive motor 20 is mounted on the second support plate 21. A first transmission assembly 15 is mounted on the second support plate 21 and connected to the output end of the drive motor 20 and one end of one set of anti-slip wheels 19. A second transmission assembly 22 is located on the side of the other set of first support plates 23 away from one set of first support plates 23 and is connected to the other end of both sets of anti-slip wheels 19. Specifically, each anti-slip wheel 19 may include a wheel body and a rotating shaft. The rotating shaft is fixedly passed through the corresponding wheel body; therefore, one end and the other end of the anti-slip wheel 19 are also the two ends of the rotating shaft.

[0039] When it is necessary to drive the two sets of anti-slip wheels 19 to rotate synchronously, the drive motor 20 is started. The drive motor 20 rotates and drives one set of anti-slip wheels 19 to rotate synchronously through the first transmission component 15. When one set of anti-slip wheels 19 rotates, it drives the other set of anti-slip wheels 19 to rotate synchronously through the second transmission component 22, thereby achieving synchronous rotation of the two sets of anti-slip wheels 19. Furthermore, by controlling the rotation direction of the drive motor 20, the two sets of anti-slip wheels 19 can be driven to rotate forward or backward to adjust the direction of movement. By using the first transmission component 15 and the second transmission component 22 in conjunction to drive the two sets of anti-slip wheels 19, the rotation of the two sets of anti-slip wheels 19 can be achieved conveniently and effectively.

[0040] In this embodiment of the invention, the specific structures of the first transmission component 15 and the second transmission component 22 may include, but are not limited to, a belt drive structure, that is, a mating structure of two sets of transmission wheels and a transmission belt, wherein the transmission belt meshes with or frictionally engages with the transmission wheels. Specifically, as shown... Figure 12 As shown, the two sets of transmission wheels of the first transmission assembly 15 are respectively connected to the output end of the drive motor 20 and one end of one set of anti-slip wheels 19, and the transmission belt is sleeved on the outside of the corresponding two sets of transmission wheels; the two sets of transmission wheels of the second transmission assembly 22 are respectively connected to the other ends of the two sets of anti-slip wheels 19, and the transmission belt is sleeved on the outside of the corresponding two sets of transmission wheels. This transmission method provides stable transmission and higher efficiency. Furthermore, the second support plate 21 is perpendicularly distributed to one set of the first support plates 23, which effectively reduces the space occupied by the first transmission assembly 15 and the second transmission assembly 22, resulting in higher integration, no interference, and higher reliability.

[0041] In this embodiment of the invention, such as Figures 11 to 15 As shown, the lifting assembly may include two sets of third support plates 17, slides 25, lead screws 26, top plates 24, springs 27, and rotating components.

[0042] One end of each of the two sets of third support plates 17 is connected to one of the two sets of first support plates 23. Specifically, one end of each of the two sets of third support plates 17 is rotatably connected to the corresponding first support plate 23. The slide block 25 is slidably disposed between the two sets of third support plates 17. The lead screw 26 is threaded through the slide block 25. The top plate 24 is disposed between the two sets of first support plates 23 and between the two sets of anti-slip wheels 19. The spring 27 is sleeved on the outside of the lead screw 26. One end of the spring 27 is connected to the top plate 24, and the other end of the spring 27 is connected to the slide block 25. The rotating assembly is disposed at the other end of the two sets of third support plates 17, and its output end is connected to the bottom end of the lead screw 26 for driving the lead screw 26 to rotate. Specifically, the rotating assembly is rotatably connected to the other end of the two sets of third support plates 17.

[0043] Before lifting the two sets of first support plates 23 and the two sets of anti-slip wheels 19, the initial height can be 188mm. When lifting the two sets of first support plates 23 and the two sets of anti-slip wheels 19, the rotating assembly is activated to drive the lead screw 26 to rotate. Since the lead screw 26 is threadedly connected to the slide 25, when the lead screw 26 rotates, it will drive the slide 25 to move, that is, the lead screw 26 will be relatively extended. At this time, the two sets of third support plates 17 lift the two sets of first support plates 23 and the two sets of anti-slip wheels 19, and gradually contact the side wall of the support rope 30. Further, after the two sets of anti-slip wheels 19 contact the side wall of the support rope 30, the rotating assembly is driven to continue to drive the slide 25 to move and compress the spring 27. The reaction force of the spring 27 can, on the one hand, make the two sets of anti-slip wheels 19 and the support rope 30 closely abut, increasing the friction; on the other hand, it can also dampen and buffer the movement of the two sets of anti-slip wheels 19, improving the reliability of the movement of the housing 1. Furthermore, when the pressure between the two sets of anti-slip rollers 19 and the supporting rope 30 reaches a specified pressure, a pressure sensor can provide feedback to the microcontroller, which then controls the rotating assembly to stop. At this point, the height can be up to 213mm, making it more intelligent and convenient. When it is not necessary to lift the two sets of first support plates 23 and the two sets of anti-slip rollers 19 to disengage them from the sidewalls of the supporting rope 30, the rotating assembly can be started in reverse to reset the two sets of first support plates 23 and the two sets of anti-slip rollers 19.

[0044] In this embodiment of the invention, such as Figures 11 to 15 As shown, the rotating assembly may include a control motor 18 and a reduction gearbox 16.

[0045] The control motor 18 is located at the other end of the two sets of third support plates 17, and the reduction gearbox 16 is located at the output end of the control motor 18 and below the lead screw 26. The bottom end of the lead screw 26 is connected to the output end of the reduction gearbox 16. Specifically, the specific structure of the reduction gearbox 16 may include, but is not limited to, right-angle reduction gearboxes, worm gear reduction gearboxes, etc., as known to those skilled in the art. Specifically, the other ends of the two sets of third support plates 17 are rotatably connected via a first rotating rod located inside the housing 1, the control motor 18 is rotatably connected to the other ends of the two sets of third support plates 17, and the reduction gearbox 16 is rotatably connected via a second rotating rod located inside the housing 1.

[0046] When it is necessary to lift the two sets of first support plates 23 and the two sets of anti-slip wheels 19, the control motor 18 is started, driving the lead screw 26 to rotate through the reduction gearbox 16. The lead screw 26 then drives the slide block 25 to slide along the two sets of third support plates 17. Since the control motor 18 and the reduction gearbox 16 are rotatably connected to the corresponding rotating rods, i.e., their height positions are relatively limited, the two sets of first support plates 23 and the two sets of anti-slip wheels 19 can be pushed up to abut against the side wall of the support rope 30. When it is not necessary to lift the two sets of first support plates 23 and the two sets of anti-slip wheels 19, the control motor 18 is driven to rotate in the opposite direction, causing the control motor 18 and the reduction gearbox 16 to tilt, thereby causing the two sets of first support plates 23 and the two sets of anti-slip wheels 19 to disengage from the abutment state with the support rope 30. This lifting method makes the movement of the housing 1 more stable and flexible.

[0047] In this embodiment of the invention, the shape of the third support plate 17 may include a Z-shape to make way for the second support plate 21 and the first transmission assembly 15. This approach can further improve the integration of the device.

[0048] In this embodiment of the invention, such as Figure 2 , Figures 5 to 10 As shown, the storage assembly may include a guide plate 14, a guide hole 13, a sliding assembly, a stop 39, and a pushing assembly. Specifically, the sliding assembly may include a frame 8 and an L-shaped plate 6.

[0049] A guide plate 14 is disposed on the inner wall / side plate 4 of the housing 1. A guide hole 13 is formed on the side plate 4 of the housing 1 and is directly opposite to the guide plate 14. A sliding assembly is disposed at one end of the guide plate 14. One end of the frame 8 extends to the side of the housing 1 near the guide plate 14 and fits against it. An L-shaped plate 6 is disposed inside the frame 8. One end of the L-shaped plate 6 is rotatably connected to the inner wall of the frame 8 via a pivot 9. The other end of the L-shaped plate 6 extends into the interior of the guide hole 13, and the tip of the L-shaped plate 6 extends out of the interior of the frame 8 to form a V-shape. A stop block 39 is disposed on the inner wall of the third support frame. A pushing assembly is disposed on the inner wall of the housing 1, and its output end is connected to the sliding assembly. It is used to drive the frame 8 to move along the extension direction of the guide plate 14, causing the L-shaped plate 6 to rotate and extend out of the guide hole 13 to abut against the stop block 39. Specifically, the guide plate 14 is L-shaped and connected to the inner wall of the side plate 4 of the housing 1. The guide hole 13 is located above the horizontal section of the guide plate 14. The frame 8 is located at one end of the guide plate 14 and can slide inside the L-shape of the guide plate 14. In the initial state, the L-shaped plate 6 is distributed in a V-shape inside the frame 8. The tip / right-angle end of the L-shaped plate 6 is close to the vertical section of the guide plate 14, and the outer wall of the L-shaped plate 6 is in contact with one end of the guide plate 14.

[0050] When the hanging rack 34 needs to be further folded and stored, the pushing component is activated, driving the frame 8 to move along the extension direction of the guide plate 14. Since the tip of the L-shaped plate 6 extends out of the frame 8 and is abutted against one end of the guide plate 14, as the frame 8 slides along the L-shape of the L-shaped plate 6, one end of the guide plate 14 limits the tip of the L-shaped plate 6 to rotate until one side is abutted against the guide surface of the guide plate 14. At this time, the other side of the L-shaped plate 6 extends a guide hole 13 perpendicularly distributed to the side plate 4 and extending into the groove. As the frame 8 continues to slide, the L-shaped plate 6 maintains this state and moves synchronously until it abuts against the stop 39 on the third support frame. As the pushing component continues to push, since the stop 39 is fixed in position, the abutment between the L-shaped plate 6 and the stop 39 acts on the housing 1, causing the housing 1 to push the hanging rack 34 to be further folded and stored. Specifically, the housing 1 acts on / pushes the second support frame 33 so that the second support frame 33 approaches along one of the sets of crossbeams 40, and the two sets of hinge rods 32 gradually become perpendicular to the first support frame 31 and the second support frame 33, which can lift / raise the hanging net frame 34 to detach it from the supporting rope, so as to realize the folding, storage and locking of the hanging net frame 34.

[0051] In this embodiment of the invention, such as Figures 2 to 4As shown, the first support frame 31 may include two sets of first horizontal bars, and the second support frame 33 may include two sets of second horizontal bars. The two ends of the two sets of first horizontal bars are connected by two sets of third rotating rods, and the two ends of the two sets of second horizontal bars are connected by two sets of fourth rotating rods. Further, one set of hinged rods 32 also comprises two sets of first vertical bars, with their ends rotatably connected to the same end of the first and second horizontal bars, respectively. The other set of hinged rods 32 comprises two sets of second vertical bars and two sets of third vertical bars. The top ends of the two sets of second vertical bars are hinged to the two sets of second horizontal bars and located inside the two sets of second horizontal bars; the bottom ends of the two sets of third vertical bars are hinged to the two sets of first horizontal bars and located outside the two sets of first horizontal bars. The opposite ends of the second and third vertical bars are connected. Further, it may also include two sets of support rods 35, with one end of each support rod 35 inclined upwards at an obtuse angle and hinged to the opposite ends of the second and third vertical bars. The other end of the support plate is hinged to the middle of one set of hinged rods 32. This structure allows the shell 1 to push the tops of the two sets of second vertical rods from an inclined position to a vertical position, while simultaneously driving the two sets of third vertical rods to rotate synchronously along the corresponding first horizontal rods. The two sets of second horizontal rods then drive the two sets of first vertical rods to rotate synchronously, thus achieving a transformation from a parallelogram to a rectangle, which also achieves the folding and locking of the hanging frame 34. Specifically, while the parallelogram transforms into a rectangle, the second support frame 33 can lift the hanging frame 34 to detach it from the supporting rope 30. When it is necessary to unlock the hanging frame 34, the control push component drives the frame 8 and the L-shaped plate 6 to reset, the hinge rod 32 loses its constraint, and the whole changes from a rectangle to a parallelogram. At this time, the lifting component and the drive component can control the two sets of anti-slip wheels 19 to move along the supporting rope 30 to extend the hanging frame 34.

[0052] In this embodiment of the invention, such as Figures 2 to 4 As shown, the third support frame may include two sets of third crossbars 36 and two sets of inverted U-shaped frames 37.

[0053] Two sets of third crossbars 36 are respectively connected to one end of two sets of support rods 35, and two sets of inverted U-shaped frames 37 are respectively set at both ends of the two sets of third crossbars 36, with both ends of the inverted U-shaped frames 37 connected to the same end of the two sets of third crossbars 36. Multiple sets of rollers 5 are rotatably mounted on the side plate 4 of the housing 1 for rolling in cooperation with the tops of the two sets of third crossbars 36. Furthermore, a retaining groove is formed on the opposite side of the two sets of third crossbars 36, that is, on the side opposite to the side plate 4 of the housing 1.

[0054] In this embodiment of the invention, such as Figures 2 to 4As shown, the hinge assembly may further include a fourth support frame 38. Specifically, one end of the fourth support frame 38 is connected to the first support base 28 and is located below the first support frame 31, and the other end of the fourth support frame 38 is connected to the end of the first support frame 31 away from the first support base 28, so as to cooperate with the first support frame 31 to form a triangular shape and improve the structural strength of the hinge assembly.

[0055] In this embodiment of the invention, such as Figures 5 to 10 As shown, the sliding component may include a slider 10 and a slide rail 11.

[0056] The slider 10 is located on the top of the frame 8, and the slide rail 11 is located on the inner wall of the side plate 4 of the housing 1, with the slider 10 and the slide rail 11 slidingly engaged.

[0057] When the pusher pushes the frame 8 to slide / move along the guide plate 14, the slider 10 slides synchronously along the corresponding slide rail 11 to ensure the reliability and stability of the frame 8 sliding / moving inside the L-shape of the guide plate 14, so that the L-shaped plate 6 can abut against the stop block 39.

[0058] In this embodiment of the invention, the specific form of the pushing component may include, but is not limited to, the lever 7, such as a pen-type lever. Specifically, the lever 7 is disposed on the inner wall of the housing 1, and the output end of the lever 7 is connected to the slider 10. Further, the lever 7 has a stroke of 55mm, and when the lever 7 extends 5mm, the L-shaped plate 6 rotates, and when it extends 50mm, it pushes forward.

[0059] In this embodiment of the invention, such as Figures 5 to 10 As shown, the rotating shaft 9 may include a torsion spring 12. Specifically, a torsion spring 12 is sleeved on the outer side of the rotating shaft 9, one end of the torsion spring 12 is connected to one end of the L-shaped plate 6, and the other end of the torsion spring 12 is connected to the inner wall of the frame 8.

[0060] When the guide plate 14 restricts the L-shaped plate 6 and the frame 8 moves along the L-shaped interior / guide surface of the guide plate 14, the L-shaped plate 6 rotates until one side is in contact with the guide surface of the guide plate 14, simultaneously compressing the torsion spring 12. The torsion spring 12 remains compressed during the subsequent continuous movement of the L-shaped plate 6. When it is necessary to unlock the hanging frame 34, the L-shaped plate 6 returns to its original position along the guide plate 14 until it is no longer restricted by the guide surface of the guide plate 14. Under the action of the torsion spring 12, the L-shaped plate 6 returns to a V-shape, facilitating the next storage of the hanging frame 34.

[0061] In this embodiment of the invention, such as Figure 1 as well as Figure 16 As shown, the locking device may include a second support base 41, a second pulley 42, and a locking piece 43.

[0062] The second support base 41 is mounted on another set of crossbeams 40, and the second pulley 42 is rotatably mounted on the second support base 41. The supporting rope 30 is wound around the second pulley 42. The locking plate 43 is mounted on the second support base 41 near the traction device.

[0063] The second support base 41 is fixedly installed on the corresponding crossbeam 40. The second pulley 42 is inclined and symmetrically distributed with the first pulley 29, which facilitates the winding and guiding of the supporting rope 30. Furthermore, the locking piece 43 can be inserted and locked into the housing 1.

[0064] In this embodiment of the invention, such as Figure 5 As shown, the traction device may also include a locking hole 3 and a limiting component.

[0065] The locking hole 3 is provided on the side of the housing 1 near the locking piece 43. The limiting component is provided inside the housing 1 to limit the locking piece 43 when it enters the housing 1 along the locking hole 3.

[0066] When the housing 1 moves to the locking piece 43, the locking piece 43 enters along the locking hole 3 and is limited by the limiting component inside the housing 1 to achieve locking and fixing of the housing 1 and the hanging frame 34. Further, the specific form of the limiting component can be determined according to the specific form of the locking piece 43. Specifically, the locking piece 43 may include an L-shaped hook, and the limiting component may include an L-shaped locking block that engages with the hook lock and a control structure that drives the L-shaped locking block to move up and down. Specifically, the control structure may include a motor and cam engagement structure known to those skilled in the art, such as a motor located inside the housing 1, a cam located at the output end of the motor, and an L-shaped locking block slidably connected to the inner wall of the housing 1, located above the cam and in contact with the top side wall of the cam. When it is necessary to lock the locking piece 43, the motor controls the cam to rotate, causing the L-shaped locking block to descend and lock into the locking piece 43; conversely, it controls the cam to rotate in the opposite direction, causing the L-shaped locking block to rise and disengage from the locking piece 43.

[0067] In this embodiment of the invention, further considering the reliability of locking the locking piece 43 to the housing 1, the number of the locking piece 43, the locking hole 3, and the limiting components can be two sets.

[0068] On the other hand, the present invention also provides a method for blocking networks using the above-mentioned network blocking system, specifically, as follows: Figure 17 As shown, the method of blocking the network may include: In step S1, two sets of crossbeams 40 are placed at both ends of the gantry frame. The gantry frame is also the top / output end of the crane, and the two sets of crossbeams 40 are installed parallel to each other at the output ends of the two cranes.

[0069] In step S2, the two sets of crossbeams 40 are driven to be lifted in parallel to the preset height.

[0070] In step S3, the supporting rope 30 is sequentially passed through the corresponding net rope storage device and the traction device. The end of the supporting rope 30 can be equipped with a traction rope, allowing a 3mm traction rope to pass through the net rope storage device and the traction device, with a length exceeding 10 meters after passing through the thickest part.

[0071] In step S4, the drone is driven to pull the support rope 30 through the corresponding locking device and fix the end of the support rope 30. Specifically, the drone can be equipped with a 3mm traction rope and fly to another set of crossbeams 40, passing it through the locking device and winding it along the second pulley 42 until it lands on the ground. The 3mm traction rope is then connected to a rope pulling machine, which works to wind the 3mm traction rope until it transitions to the 22mm diameter support rope 30, which is then fixed in place.

[0072] In step S5, the driving traction device moves along the corresponding support rope 30, causing the hanging frame 34 to move and extend to unfold the net rope. The traction device moves from the net rope storage device toward the corresponding locking device.

[0073] In step S6, it is determined whether the traction device has moved to the corresponding locking device. This can be determined by manual observation or by whether the locking piece 43 has entered the corresponding locking hole 3.

[0074] In step S7, when it is determined that the traction device has moved to the corresponding locking device, the traction device is locked, and the net sealing is determined to be complete. The locking device fixes the traction device, ensuring that the net hanging frame 34 and the net ropes below it are evenly deployed, thus achieving a stable and reliable net sealing.

[0075] In step S8, the net closing signal is acquired. This net closing signal can be acquired based on the actual situation and may include manual signals or control signals.

[0076] In step S9, the traction device is disengaged from the locking state of the locking device. The traction device can be unlocked via the locking device.

[0077] In step S10, the driving traction device moves in the opposite direction along the corresponding supporting rope 30, causing the hanging frame 34 to move and fold to store the net rope. Specifically, the traction device moves the hanging frame 34 from another set of crossbeams 40 to one of the sets of crossbeams 40 to reset, thereby storing the net rope.

[0078] In step S11, it is determined whether the traction device has moved to the corresponding net rope storage device. This can be determined manually.

[0079] In step S12, if it is determined that the traction device has moved to the corresponding net rope storage device, the net retrieval is completed.

[0080] In steps S1 to S12, the two sets of crossbeams 40, the net rope storage device, the traction device, and the locking device are first installed on two sets of cranes, respectively. Simultaneously, the supporting rope 30 is passed through the net rope storage device and the traction device. The cranes are then driven to raise the above-mentioned devices to a certain height, and a drone is used to pull the supporting rope 30 to the locking device and connect it to the rope traction machine. After connection, the traction device is driven to move along the supporting rope 30 to extend the net frame 34 and the net rope until it is locked with the locking device, thus achieving the purpose of net laying. When it is necessary to dismantle or retrieve the net, the locking device is driven to disengage from the traction device, and the traction device is driven to reset along the supporting rope 30, thus achieving net rope storage. This net sealing method effectively improves the intelligence and automation of net sealing, making net sealing more efficient and reliable.

[0081] Through the above technical solution, the netting system and method for the crossing frame provided by the present invention effectively increases the netting area by setting two sets of crossbeams 40 at both ends of the crossing frame, and distributing multiple sets of net rope storage devices and multiple sets of locking devices at equal intervals on the corresponding crossbeams 40. Simultaneously, multiple sets of traction devices are connected to the other end of the corresponding hanging net frame 34. When the hanging net frame 34 moves along the corresponding supporting rope 30 from one set of crossbeams 40 to another set of crossbeams 40, it can pull the corresponding hanging net frame 34 to extend and drive the net ropes below to form the net; after the traction device moves... When moving to another set of crossbeams 40, the corresponding locking device can be used to lock and fix it to achieve stable netting. Conversely, when the traction device needs to move along the corresponding support rope 30 from another set of crossbeams 40 to one of the crossbeams 40, the corresponding locking device is opened, causing the traction device to disengage from the lock, pulling the corresponding hanging net frame 34 to fold and reset, and driving the net rope below it to fold and store synchronously, so as to achieve the purpose of netting disassembly. The above structure can effectively improve the efficiency and convenience of netting, making it more intelligent and reliable, while also ensuring the safety of netting.
