Description

Technical Field

[0001] This utility model relates to the field of grasping and transferring fire-fighting plastic pipe fittings, and in particular to an automatic grasping and transferring device for fire-fighting plastic pipe fittings. Background Technology

[0002] With the rapid development of modern industrial automation, the fire equipment manufacturing industry is also undergoing a profound transformation from traditional labor-intensive production to automated and intelligent production. Among them, fire-fighting plastic pipe fittings are widely used in various fire protection systems due to their advantages such as corrosion resistance, light weight, and relatively low cost.

[0003] Currently, existing pipe clamping and conveying devices on the market still have some problems. For example, plastic pipes, especially those that have undergone surface treatment or have inherent material characteristics, usually have very smooth outer surfaces with extremely low coefficients of friction. The flat or textured finger surfaces commonly used in traditional grippers have limited contact area when gripping with clamping force alone, making it impossible to form an effective lock. When the grippers accelerate, decelerate, or turn, relative sliding can easily occur between the smooth pipe surface and the gripper finger surfaces, causing the clamping force to fail instantly, resulting in the workpiece slipping and falling. This can not only lead to production interruptions and material losses, but may also cause safety accidents and damage to surrounding equipment during high-speed movement. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an automatic gripping and transferring device for fire-fighting plastic pipe fittings. By rotating the components, the connecting frame with the clamping parts does not rely on traditional clamping force, thus avoiding indentations or scratches on the pipe fitting surface caused by clamping contact and greatly reducing the potential risk of damage to the pipe fitting surface.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic gripping and transferring device for fire-fighting plastic pipe fittings, comprising a base, a connecting plate fixedly connected to the left end of the outer wall of the base, a sliding plate slidably connected to the rear end of the outer wall of the connecting plate, a bottom plate slidably connected to the right end of the sliding plate, a fixing plate fixedly connected to the rear side of the bottom end of the bottom plate, a second motor fixedly connected to the rear end of the fixing plate, the driving end of the second motor penetrating through the inner wall of the fixing plate and fixedly connected to a rotating rod, a rotating assembly provided on the outer wall of the rotating rod, and the rotating rod connected to a first rotating plate through the rotating assembly.

[0006] Furthermore, the rotating assembly includes a second rotating plate rotatably connected to the outer wall of the rotating rod, a first rotating plate rotatably connected to the left end of the outer wall of the second rotating plate, a top plate rotatably connected to the bottom end of the first rotating plate, a connecting frame fixedly connected to the right end of the top plate, a rotating column fixedly connected to the left end of the connecting frame, and the outer wall of the rotating column rotatably connected to the inner wall of the bottom plate.

[0007] Furthermore, the outer wall of the rotating rod is rotatably connected to the right end of the inner wall of the base plate, a sliding column is fixedly connected to the right end of the outer wall of the connecting frame, and a sliding groove is provided at the bottom end of the inner wall of the base plate, the sliding groove being used to allow the sliding column to slide.

[0008] Furthermore, the right end of the connecting frame is threadedly connected to a second threaded rod, the front end of the second threaded rod is rotatably connected to a plug, the outer wall of the plug is slidably connected to the inner wall of the connecting frame, and a locking block is provided on the outer wall of the plug.

[0009] Furthermore, a locking element is fixedly connected to the right end of the locking block. The locking element is used to grip and remove anti-plastic pipe fittings. A slot is provided on the inner wall of the locking block, and the size of the slot is adapted to the plug-in.

[0010] Furthermore, a first motor is fixedly connected to the top right side of the base. The drive end of the first motor passes through the inner wall of the base and is fixedly connected to a first threaded rod.

[0012] This utility model has the following beneficial effects: In this invention, by rotating the component, the connecting frame and the clamping parts do not rely on the clamping force in the traditional sense, thus avoiding indentations or scratches on the surface of the pipe caused by clamping contact. This greatly reduces the potential risk of damage to the surface of the pipe and also ensures that the pipe will not easily slip off during the transfer process, thus guaranteeing the stability and reliability of the transfer.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figure 3 - Figure 5This utility model provides an embodiment of an automatic gripping and transferring device for fire-fighting plastic pipe fittings, comprising a base 1, a connecting plate 3 fixedly connected to the left end of the outer wall of the base 1, a sliding plate 5 slidably connected to the rear end of the outer wall of the connecting plate 3, a bottom plate 7 slidably connected to the right end of the sliding plate 5, a fixing plate 8 fixedly connected to the rear side of the bottom end of the bottom plate 7, a second motor 9 fixedly connected to the rear end of the fixing plate 8, the driving end of the second motor 9 penetrating the inner wall of the fixing plate 8 and fixedly connected to a rotating rod 19, a rotating assembly provided on the outer wall of the rotating rod 19, the rotating rod 19 being connected to a first rotating plate 10 through the rotating assembly, the rotating assembly including a second rotating plate 18 rotatably connected to the outer wall of the rotating rod 19, the left end of the outer wall of the second rotating plate 18 rotatably connected to the first rotating plate 10, the bottom end of the first rotating plate 10 rotatably connected to a top plate 11, and the right end of the top plate 11... A connecting frame 12 is fixedly connected. A rotating column 17 is fixedly connected to the left end of the connecting frame 12. The outer wall of the rotating column 17 is rotatably connected to the inner wall of the base plate 7. The outer wall of the rotating rod 19 is rotatably connected to the right end of the inner wall of the base plate 7. A sliding column 16 is fixedly connected to the right end of the outer wall of the connecting frame 12. A sliding groove 15 is provided at the bottom end of the inner wall of the base plate 7. The sliding groove 15 is used to slide the sliding column 16. A second threaded rod 14 is threadedly connected to the right end of the connecting frame 12. A plug 20 is rotatably connected to the front end of the second threaded rod 14. The outer wall of the plug 20 is slidably connected to the inner wall of the connecting frame 12. A locking block 21 is clamped on the outer wall of the plug 20. A locking piece 13 is fixedly connected to the right end of the locking block 21. The locking piece 13 is used to grip and remove anti-plastic pipe fittings. A slot 22 is provided on the inner wall of the locking block 21. The size of the slot 22 is adapted to the plug 20.

[0018] Specifically, in actual operation, firstly, according to the specific specifications and type of the fire-fighting plastic pipe fittings, a matching special clamp 13 needs to be accurately selected. Then, the clamp 13 is smoothly inserted into the pre-set connecting frame 12. By manually rotating the second threaded rod 14, the insert 20 at the front end slides axially forward in the inner wall of the connecting frame 12 using its thread transmission principle until the insert 20 is fully embedded in the pre-set slot 22 on the inner wall of the locking block 21, thereby achieving rigid locking between the locking block 21 and the connecting frame 12, and finally completing the reliable installation of the clamp 13. After installation, the second motor 9 is started, and its drive end outputs power to drive the rotating rod 19 to rotate to the left. The rotation of the rotating rod 19 is transmitted through the first threaded rod welded to its outer wall. The second rotating plate 18 transmits the force to the first rotating plate 10, which is hinged to it, forcing the first rotating plate 10 to deflect around the fixed fulcrum. The rotation of the first rotating plate 10 then causes the top plate 11, which is fixed to it, to produce a vertical displacement. The downward thrust of the top plate 11 acts on the connecting frame 12, causing it to rotate clockwise downward about the rotating column 17 as the axis of rotation. During this rotation, the sliding column 16 set at the right end of the connecting frame 12 will slide smoothly in the sliding groove 15 preset at the bottom of the inner wall of the base plate 7, effectively ensuring the stability and accuracy of the entire rotation process of the connecting frame 12. At the same time, through the linkage of the connecting frame 12, after the connecting frame 12 rotates to the bottom, the installed clamp 13 will rotate downward synchronously to a pre-set 90°.

[0019] Reference Figure 1 and Figure 2 A first motor 2 is fixedly connected to the top right side of the base 1. The drive end of the first motor 2 passes through the inner wall of the base 1 and is fixedly connected to a first threaded rod 4. The outer wall of the first threaded rod 4 is rotatably connected to the inner wall of the connecting plate 3. The top end of the outer wall of the first threaded rod 4 is threadedly connected to the bottom end of the outer wall of the slide plate 5. An electric push rod 6 is fixedly connected to the top of the slide plate 5. A push plate is fixedly connected to the left end of the outer wall of the base plate 7. The top end of the push plate is fixedly connected to the drive end of the electric push rod 6. The outer wall of the push plate is slidably connected to the inner wall of the slide plate 5.

[0020] Specifically, by starting the first motor 2, its drive end drives the first threaded rod 4 to rotate. Since the top of the outer wall of the first threaded rod 4 is connected to the bottom of the outer wall of the slide plate 5 through a precision threaded pair, the rotation of the first threaded rod 4 is converted into linear sliding of the slide plate 5 on the rear guide rail of the connecting plate 3, so that the slide plate 5 moves to a precise position slightly to the left of the top of the pipe fitting. When the slide plate 5 reaches the target position, the electric push rod 6 installed at its top is activated. The drive end of the electric push rod 6 extends downward, driving the push plate to slide downward in the guide structure inside the slide plate 5, thereby pushing the push plate fixed to the right end of the push plate. The base plate 7 is vertically adjusted. By precisely controlling the extension and retraction stroke of the electric push rod 6, the horizontal position of the base plate 7 is precisely adjusted so that the hole on the clamp 13 can be fully aligned and moved directly below the pipe. Finally, the second motor 9 is started in reverse so that it drives the rotating rod 19 to rotate in the opposite direction. Through the reverse action of the aforementioned transmission mechanism, the connecting frame 12 drives the clamp 13 to rotate upward, smoothly lifting the pipe and precisely aligning its hole with the clamping hole on the clamp 13. Once the pipe is fully inserted into the hole of the clamp 13, it can enter the transfer state.

[0021] Working principle: In actual operation, firstly, select the corresponding clamp 13 according to the different fire-fighting plastic pipe fittings, insert it into the connecting frame 12, and rotate the second threaded rod 14. The second threaded rod 14 will drive the front end plug 20 to slide forward in the inner wall of the connecting frame 12, inserting the plug 20 into the slot 22 opened in the inner wall of the locking block 21, thereby fixing the locking block 21 to the connecting frame 12, and thus completing the installation of the clamp 13. Then, start the second motor 9, whose drive end drives the rotating rod 19 to rotate to the left. When the rotating rod 19 rotates, it will drive the second rotating rod on the outer wall to rotate to the left. The movable plate 18 moves accordingly. Since the second rotating plate 18 is rotatably connected to the first rotating plate 10, the second rotating plate 18 will push the first rotating plate 10 to rotate. The rotation of the first rotating plate 10 will drive the top plate 11 to move. The top plate 11 will then push the connecting frame 12 to rotate downward around the rotating column 17 as the axis. When the connecting frame 12 rotates, the sliding column 16 at its right end will slide in the sliding groove 15 at the bottom of the inner wall of the base plate 7 to ensure the stability of the connecting frame 12 during rotation. Then, after the connecting frame 12 has rotated to the bottom, the clamp 13 will rotate downward by exactly 90°.

[0022] Then, the first motor 2 is started, and its driving end drives the first threaded rod 4 to rotate, causing the first threaded rod 4 to drive the slide plate 5 to slide on the rear end of the outer wall of the connecting plate 3, thereby adjusting the slide plate 5 to a position slightly to the left above the pipe. Then, when the electric push rod 6 at the top of the slide plate 5 is started, its driving end drives the push plate to slide down on the inner wall of the slide plate 5, causing the bottom plate 7 at the right end of the push plate to slide down, thereby adjusting the horizontal position of the bottom plate 7, so that the hole on the clamp 13 is completely below the pipe. Then, the second motor 9 is started in reverse, causing it to rotate in the opposite direction, lifting the pipe and clamping it into the hole, after which it can be transferred.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
