Description

Technical Field

[0001] This utility model relates to the technical field of gate grabbing devices, and specifically discloses a novel sluice gate grabbing device. Background Technology

[0002] In water conservancy and hydropower construction, flap gates, sluice gates, and rubber dams are widely used to meet the needs of urban water use, landscape construction, environmental remediation, irrigation, and power generation. The academic name for steel dams is bottom-shaft driven flap gates, a new type of gate capable of bidirectional water blocking, flexible opening and closing, steplessly adjustable gate opening, convenient scheduling, concealed engineering, unimpeded flood control and navigation, and improved river landscape. These gates utilize a grabbing device during operation.

[0003] Chinese patent CN218712709U discloses an automatic beam-grabbing device for opening and closing gates, including a beam-grabbing body and an electric hoist drive mechanism. Two sets of electric hoist drive mechanisms are provided, and the bottom of each set is connected to the top wall of the beam-grabbing body via a fixed frame. A stabilizing mechanism is provided at the bottom of each fixed frame. Clamping blocks are slidably arranged on both sides of the stabilizing mechanism. An arc-shaped groove is formed on the inner side of each clamping block, and a movable rod is rotatably installed inside each arc-shaped groove. Connecting components are provided on both sides of each clamping block. A steel wire rope is fixedly connected to the winding end of the electric hoist drive mechanism. This invention ensures greater stability of the hoisted gate below during the winding of the electric hoist drive mechanism, preventing excessive swaying and facilitating lifting. Furthermore, it can automatically position the hanging lugs without requiring manual assistance.

[0004] The aforementioned document discloses an automatic gate-grabbing device that uses a bidirectional hydraulic cylinder to drive a hook to grab the gate plate. This device is costly, and it uses an electric hoist to lift the gate plate with a steel rope. Although a limit mechanism is provided for the steel rope, it still swings during the lifting and winding process, resulting in inaccurate gate positioning. Therefore, a new type of gate-grabbing device is needed to solve this problem. Utility Model Content

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0025] Please see Figure 1-5A novel sluice gate gripping device includes a gantry frame 1, a slide plate 3 that can move up and down, and a gate plate 13. The outer wall of the gantry frame 1 is provided with a drive mechanism for driving the slide plate 3 to move up and down. The outer wall of the slide plate 3 is provided with a gripping mechanism. The gripping mechanism includes a rotating shaft 7 rotatably connected inside the slide plate 3. A sleeve 9 is fixedly connected to the lower end face of the rotating shaft 7. A groove 23 is opened on the lower end face of the sleeve 9. A through groove 14 is opened inside the sleeve 9. A plurality of second sliding grooves 15 communicating with the through groove 14 are opened inside the sleeve 9. A locking block 17 is slidably connected inside the plurality of second sliding grooves 15. A sliding rod 16 extending to the outside of the sleeve 9 is fixedly connected to one end of the plurality of locking blocks 17 that is far away from each other. A limit plate 19 is fixedly connected to the other end of the plurality of sliding rods 16. A spring 18 located inside the second sliding groove 15 is sleeved on the outer wall of the plurality of sliding rods 16.

[0026] A connecting shaft 20 is fixedly connected to the upper end face of the gate plate 13, and a first truncated cone 21 is fixedly connected to the upper end face of the connecting shaft 20. A second truncated cone 22, which is arranged in the opposite direction to the first truncated cone 21, is slidably connected to the outer wall of the connecting shaft 20.

[0027] In this embodiment: the drive mechanism drives the slide plate 3 to move downward, which in turn drives the sleeve 9 to move downward. The sleeve 9 moves downward and fits on the outside of the connecting shaft 20. The first cone 21 presses multiple locking blocks 17 outward, causing the locking blocks 17 to slide into the second slide groove 15 and compress the spring 18. The sleeve 9 continues to move downward. When the locking blocks 17 are below the first cone 21, the locking blocks 17 slide inward under the elastic force of the spring 18 and are locked below the first cone 21. At this time, the lower end face of the sleeve 9 is exactly against the upper end face of the gate 13, so that the sleeve 9 cannot continue to move downward. The drive mechanism drives the slide plate 3 to move upward, which in turn drives the gate 13 to move upward through the locking blocks 17 and the first cone 21.

[0028] When the gate 13 is to be lowered, the rotating shaft 7 is rotated 90 degrees, thereby aligning the groove 23 with the gate 13. At this time, the sleeve 9 can continue to move downward, driving the slide plate 3 to continue moving downward through the drive mechanism, which in turn drives the sleeve 9 to continue moving downward. The sleeve 9 further drives the locking block 17 to move downward, causing the second cone 22 to press the locking block 17 outward. When the locking block 17 moves to below the second cone 22, the drive mechanism drives the sleeve 9 to move upward, which in turn drives the locking block 17 to move upward, thereby driving the second cone 22 to move downward and fit against the first cone 21. At this time, the sleeve 9 continues to move upward, which can drive the locking block 17 to disengage from below the first cone 21, thereby disengaging the sleeve 9 from the outside of the connecting shaft 20 and lowering the gate 13. This utility model, through mechanical structure design, can automatically grab and lower the gate 13 during the lifting and lowering process of the sleeve 9, and has a low cost.

[0029] As a technical optimization of this utility model, the driving mechanism includes a threaded rod 4 rotatably connected to the inner wall of the portal frame 1, a limiting rod 6 fixedly connected to the inner wall of the portal frame 1, and a first servo motor 5 installed on the upper end face of the portal frame 1 and whose output end is fixedly connected to the threaded rod 4. The slide plate 3 is threadedly connected to the threaded rod 4, and the limiting rod 6 is slidably connected to the slide plate 3.

[0030] In this embodiment: the first servo motor 5 is started, and the first servo motor 5 drives the threaded rod 4 to rotate, which in turn drives the slide plate 3 to move up and down along the limiting rod 6.

[0031] As a technical optimization of this utility model, a second servo motor 10 is installed on the upper end of the slide plate 3, and a first gear 11 is fixedly connected to the output end of the second servo motor 10. A second gear 12 that meshes with the first gear 11 is fixedly connected to the outer wall of the rotating shaft 7.

[0032] In this embodiment: the second servo motor 10 is started, the second servo motor 10 drives the first gear 11 to rotate, which in turn drives the second gear 12 to rotate, and the second gear 12 further drives the rotating shaft 7 to rotate, thereby facilitating the rotation of the rotating shaft 7 by 90 degrees.

[0033] As a technical optimization of this utility model, a limiting ring 8 located above the slide plate 3 is fixedly connected to the outer wall of the rotating shaft 7.

[0034] In this embodiment, the limiting ring 8 is used to limit the rotation shaft 7 and prevent the rotation shaft 7 from coming off the slide plate 3.

[0035] As a technical optimization of this utility model, the inner wall of the portal frame 1 has two symmetrically distributed first sliding grooves 2, and the threaded rod 4 and the limiting rod 6 are respectively arranged inside the two first sliding grooves 2.

[0036] In this embodiment: by opening two symmetrically distributed first sliding grooves 2 on the inner wall of the portal frame 1, it is convenient to install the threaded rod 4 and the limiting rod 6.

[0037] As a technical optimization of this utility model, the inner wall of the gantry frame 1 is fixedly connected with two slide rails 24 that are slidably connected to the gate plate 13.

[0038] In this embodiment, by fixing two slide rails 24 to the inner wall of the gantry frame 1, it is convenient to limit the gate 13 and make the gate 13 move up and down stably.

[0039] As a technical optimization of this utility model, a controller is provided on the outer wall of the portal frame 1, and the first servo motor 5 and the second servo motor 10 are both electrically connected to the controller.

[0040] In this embodiment, the controller facilitates the normal operation of the first servo motor 5 and the second servo motor 10.

[0041] The working principle and usage process of this utility model: When gripping the gate plate 13, the first servo motor 5 is started. The first servo motor 5 drives the threaded rod 4 to rotate, which in turn drives the slide plate 3 to move downward along the limit rod 6, which in turn drives the sleeve 9 to move downward. The sleeve 9 moves downward and fits on the outside of the connecting shaft 20. It also squeezes multiple locking blocks 17 outward through the first conical pedestal 21, so that the locking blocks 17 slide into the second sliding groove 15 and compress the spring 18. The sleeve 9 continues to move downward. When the locking blocks 17 are below the first conical pedestal 21, the locking blocks 17 slide inward under the elastic force of the spring 18 and are locked below the first conical pedestal 21. At this time, the lower end face of the sleeve 9 is just against the upper end face of the gate plate 13, so that the sleeve 9 cannot continue to move downward. The drive mechanism drives the slide plate 3 to move upward, which in turn drives the gate plate 13 to move upward through the locking blocks 17 and the first conical pedestal 21.

[0042] When the gate 13 is to be lowered, the second servo motor 10 is activated. The second servo motor 10 drives the first gear 11 to rotate, which in turn drives the second gear 12 to rotate. The second gear 12 further drives the rotating shaft 7 to rotate 90 degrees, thereby aligning the groove 23 with the gate 13. At this time, the sleeve 9 can continue to move downwards, driving the slide plate 3 to continue moving downwards through the drive mechanism, which in turn drives the sleeve 9 to continue moving downwards. The sleeve 9 further drives the locking block 17 to move downwards, causing the second cone 22 to press the locking block 17 outwards. When the locking block 17 moves to the second cone... When the second conical truss 22 is below the first conical truss 21, the sleeve 9 is driven upward by the drive mechanism. The sleeve 9 further drives the locking block 17 upward, which in turn drives the second conical truss 22 downward to fit against the first conical truss 21. At this time, the sleeve 9 continues to move upward, which can drive the locking block 17 to disengage from below the first conical truss 21, thereby disengaging the sleeve 9 from the outside of the connecting shaft 20 and lowering the gate 13. Through mechanical structure design, this utility model can automatically grab and lower the gate 13 during the lifting and lowering process of the sleeve 9. The cost is low, and the gate 13 is lifted and lowered by the threaded rod 4, which makes the positioning more accurate.
