[0031] Example: See Figure 1-Figure 7 A fully automatic pipe reel comprises a frame 1, a reel device, a pipe clamping device and a brake mechanism.

[0032] The frame 1 is a frame structure and is formed by welding metal rods / tubes; the frame 1 is a rectangular structure and has two layers, a roller 2 is provided at the bottom, and a bracket 3 is provided at the top of both sides of the frame 1, that is, on the frame 1.

[0033] The reel device comprises a reel and a support shaft, and a hose 4 is wound around the reel. The reel is rotatably connected to two brackets 3 through the support shaft, and a coil spring 5 is also arranged between the reel and the support shaft. In the initial state, the coil spring 5 is in a relaxed state. In specific implementation, the reel comprises two side discs 6 and a cylinder 7 located between the two side discs 6, and the cylinder 7 is arranged coaxially with the two side discs 6 and fixedly connected. The support shaft comprises a fixed shaft 8 and a rotating shaft 9, one end of the fixed shaft 8 is connected to one end of the rotating shaft 9 through a bearing, and a groove is arranged at the end of the rotating shaft 9 connected to the fixed shaft 8, and the bearing is embedded in the groove. The other end of the fixed shaft 8 is fixedly connected to one of the brackets 3, and the other end of the rotating shaft 9 is rotatably connected to the other bracket 3. The reel is sleeved on the support shaft, one side plate of which is rotatably connected to the fixed shaft 8, and the other side plate is fixedly connected to the rotating shaft 9, and there is a spacing between the cylinder 7 and the support shaft; in this way, the reel can rotate synchronously with the rotating shaft 9, while the fixed shaft 8 does not rotate. The coil spring 5 is wound on the fixed shaft 8 , with its inner end fixedly connected to the fixed shaft 8 and its outer end fixedly connected to the cylinder 7 .

[0034] In order to facilitate the gas supply and the retraction and release of the hose 4, a channel is provided at one end of the rotating shaft 9 away from the fixed shaft 8. The channel extends to the side disc 6, bends to one side of the rotating shaft 9 and passes through the side of the rotating shaft 9. A connecting pipe 18 is fixed on the side wall of the rotating shaft 9 at a position corresponding to the channel. One end of the connecting pipe 18 is connected to the channel and closes the end of the channel. Specifically, the diameter of the connecting pipe 18 is greater than or equal to the diameter of the channel, and the outlet of the channel is closed to the inside of the connecting pipe 18. When implemented, the other end of the connecting pipe 18 extends to the position close to the outside of the cylinder 7, bends to the inside of the winding drum and passes through the side disc 6. The inner end of the hose 4 is connected to the end of the connecting pipe 18 that passes through the side disc 6; the outer end is used to output gas after stretching. A rotary joint 19 and an adapter 20 are provided at the end of the rotating shaft 9. The adapter 20 is connected to the rotating shaft 9 via the rotary joint 19, and the adapter 20 is connected to the channel; in this way, it is more convenient to connect to the gas source, and the rotation of the rotating shaft 9 will not affect the gas output.

[0035] The pipe clamping device is located on one side of the reel and is used to control the rotation or fixation of the reel. In specific implementation, the pipe clamping device includes a ratchet 10, a pawl 11 and a fixed disk 12; the ratchet 10 and the fixed disk 12 are both arranged on the fixed shaft 8, wherein the ratchet 10 is fixedly connected to the side disc 6 and has a clearance fit with the fixed shaft 8, and the fixed disk 12 is fixedly connected to the fixed shaft 8. The pawl 11 is located outside the side wall of the ratchet 10, and one end of the pawl 11 is rotatably connected to the fixed disk 12 through a connecting shaft. A tension spring 13 is provided on one side of the pawl 11, one end of the tension spring 13 is connected to the pawl 11, and the other end is connected to the fixed disk 12 through a spring seat; under the action of the tension spring 13, the pawl 11 can be tightly attached to the ratchet 10. At least one notch is provided on the circumferential surface of the ratchet 10; when the pawl 11 is located in the notch, the tension spring 13 can make the pawl 11 turn. That is, in the initial state, when the ratchet 10 rotates forward, the pawl 11 is tightly attached to the ratchet 10 and the ratchet teeth of the ratchet 10 under the action of the tension spring 13, thereby preventing the ratchet 10 from rotating in the reverse direction; when the pawl 11 is located in the notch, the pawl 11 faces in the opposite direction of the ratchet 10 under the action of the tension spring 13. At this time, if the ratchet 10 rotates in the reverse direction, the pawl 11 no longer hinders the ratchet 10, thereby allowing the ratchet 10 to rotate freely in the reverse direction; if the ratchet 10 rotates forward again, the spikes of the ratchet 10 will again drive the pawl 11 to restore its state to face the square of the ratchet 10.

[0036] The brake mechanism is located on the other side of the reel and is used to control the rotation speed of the reel. In specific implementation, the brake mechanism includes an active disc 14 and a brake disc 15, and the active disc 14 and the driven disc are both sleeved on the rotating shaft 9, wherein the active disc 14 is fixedly connected to the rotating shaft 9 or the side disc 6, and the brake disc 15 is fixedly connected to the bracket 3 or the frame 1 and is clearance-matched with the rotating shaft 9; when this scheme is implemented, the brake disc 15 is fixedly connected to the frame 1 through the outer cover 29. There are several brake blocks 16 distributed around the active disc 14, and the brake blocks 16 are connected to the active disc 14 in a sliding fit and can move in the radial direction of the active disc. As an implementation method, a slide groove is provided in the radial direction of the brake disc 15 at a position corresponding to the brake block 16, and a slider is provided in the slide groove in a sliding fit, and the brake block 16 is fixedly connected to the slider. A reset spring 17 is also provided between the brake block 16 and the middle part of the active disc 14 or the rotating shaft 9. During implementation, one end of the reset spring 17 is fixedly connected to the brake block 16, and the other end is fixedly connected to the slider, and the slider is connected to the middle of the active disk 15 through a double connecting rod. The double connecting rod is rotatably connected through a connecting shaft to ensure that the brake block 16 is located near the center of the brake disk 15 when the active disk 14 is rotating at a low speed or not rotating. A friction ring is provided on the side of the brake disk 15 close to the active disk 14, and the friction ring is coaxially arranged with the rotating shaft 9 and is located outside the active disk 14; when the active disk 14 rotates, the brake block 16 can move to the outside of the active disk 14, and when the rotation speed of the active disk 14 reaches a certain speed, the brake block 16 can overcome the pulling force of the reset spring 17 and slide to fit with the friction ring to generate friction, thereby achieving deceleration.

[0037] During implementation, a pipe arranging device is provided at the lower part of the frame 1, and the pipe arranging device includes a bidirectional screw 21, a catheter slider 22 and a guide rod 23. The two ends of the bidirectional screw 21 are rotatably connected to the two sides of the frame 1 through a support block 24, and the catheter slider 22 is threadedly connected to the bidirectional screw 21; the guide rod 23 is arranged in parallel with the bidirectional screw 21, and its two ends are fixedly connected to the two support blocks 24, respectively. The catheter slider 22 is provided with a guide hole, and is slidably connected to the guide rod 23 through the guide hole. In this scheme, the cooperation mode between the bidirectional screw 21 and the catheter slider 22 is a mature existing technology. During operation, when the catheter slider 22 moves to one end of the bidirectional screw 21 (after being fitted with the support block 24), it can automatically turn and move toward the other end of the screw until it moves to the other end of the bidirectional screw 21 (after being fitted with the support block 24), and then turns to move in the opposite direction again. A catheter frame 25 is provided on the catheter slider 22, and the outer end of the hose 4 passes through the catheter frame 25; the end of the bidirectional screw 21 close to the rotating shaft 9 passes through the support block 24 and is connected to a driven pulley 26. On the rotating shaft 9, a driving pulley 27 is provided at a position corresponding to the driven pulley 26, and a transmission belt 28 is wound around the driving pulley 27 and the driven pulley 26; the driving pulley 27 can drive the driven pulley 26 to rotate through the transmission belt 28. The diameter of the driving pulley 27 is larger than the diameter of the driven pulley 26, so that the movement speed of the catheter slider 22 is faster. As a specific embodiment, the catheter frame 25 includes two vertical rollers and two horizontal rollers, and a catheter hole is formed between the two vertical rollers and the two horizontal rollers; wherein the vertical roller is vertically arranged on the catheter slider 22 and is rotatably connected to the catheter slide seat; the two ends of the two horizontal rollers are respectively connected to the two ends of the catheter slider 22 through a vertical support rod; in this way, the friction between the hose 4 and the catheter frame 25 during the expansion and contraction process can be reduced, thereby reducing wear.

[0038] During implementation, an outer cover 29 is provided around and on the upper side of the frame 1, wherein the outer cover 29 on the frame 1 is arc-shaped and covers the reel device. On the side of the outer cover 29 close to the pipe rack, a pipe outlet hole 30 is provided corresponding to the position of the pipe rack, and the outer end of the hose 4 extends out of the pipe outlet hole 30 after passing through the conduit hole, and is connected to a connector after the hose 4 extends out of the pipe outlet hole 30. When the frame 1 is a rectangular parallelepiped, the pipe outlet hole 30 is located on the outer cover 29 close to one end of the pipe rack. During implementation, a soft buffer ball is installed at one end of the hose 4 extending out of the outer cover 29, and the volume of the buffer ball is larger than the pipe outlet hole 30; at the end of the pipe collection process, the hose 4 also has a certain speed, and the impact of the connector at the outer end of the hose 4 and the outer cover 29 is reduced by providing the buffer ball, which can effectively protect the connector.

[0039] When in use, place the hose reel in a suitable position and connect the right adapter 20 of the hose reel to the air source. Then pull out the hose 4 to drive the reel to rotate. The rotation of the reel will shrink (tighten) the internal coil spring 5 and store energy. At the same time, the reel will also drive the rotating shaft 9 to rotate, and the driving pulley 27 on the rotating shaft 9 will rotate, and the driven pulley 26 will rotate through the transmission belt 28. The driven pulley 26 will then drive the bidirectional screw 21 to rotate, and the catheter slider 22 will reciprocate on the bidirectional screw 21. During the process of pulling out the hose 4, when the reel rotates to a certain position and the pawl 11 is within the ratchet range of the ratchet wheel 10, the pawl 11 fits with the ratchet. Loosening the hose 4 will cause the pawl 11 to get stuck on the ratchet wheel 10, and the reel cannot rotate. When the pawl 11 is in the notch of the ratchet wheel 10, the pawl 11 is separated from the ratchet. Pull the hose 4 again, and the rotation of the ratchet wheel 10 will cause the pawl 11 to fit with the ratchet of the ratchet wheel 10 again. After the inflation is completed, first pull the hose 4 so that the pawl 11 is located in the notch of the ratchet 10, and then release the hose 4. At this time, the pawl 11 is directed in the opposite direction of the ratchet 10 under the action of the tension spring 13, and the elastic potential energy stored in the coil spring 5 is released, which will rebound and cause the reel to rotate in the opposite direction. At this time, the pawl 11 cannot jam the ratchet 10, and the reel rotates in the opposite direction, so that the hose 4 is recovered, and the hose 4 can be neatly arranged on the cylinder 7 under the left and right reciprocating motion of the pipe arranger.

[0040] When the reel rotates too fast, the brake block 16 on the brake disc 15 adheres to the friction ring under the action of centrifugal force and generates friction. The faster the rotation speed, the greater the friction, so that the reel starts to slow down and the tube reeling speed is not too fast, which increases the safety of the entire mechanism.

[0041] This solution sets a coil spring 5 between the cylinder 7 and the fixed shaft 8, so that the air tube can be automatically retracted by releasing the hand after the inflation is completed, without manual intervention, thus reducing the operating burden; at the same time, the automatic retraction function can effectively save space, keep the deck clean, and prevent the air tube from being scattered on the ground and affecting other ground operations. A brake mechanism is set between the frame 1 and the side disc 6. When the air tube is retracted too fast, the brake block 16 moves outward under the action of centrifugal force. When the brake block 16 contacts the friction ring, friction is generated, thereby automatically realizing the deceleration function, preventing equipment wear or accidental injury to personnel caused by excessive air tube retraction; it not only improves the safety of the tube reel, but also reduces maintenance costs and potential safety hazards. A pipe clamping device is arranged on the outside of the side disc 6, and the pipe clamping device is mainly composed of a ratchet 10 and a pawl 11. In this way, each time a section of the air pipe is pulled out, the air pipe will be locked to prevent it from retracting, so as to meet the inflation requirements of different lengths; the flexibility of operation is improved, and the cumbersome operation of manual fixing is avoided, making the inflation operation more convenient and efficient; at the same time, a notch is arranged on the ratchet 10, so that when the pawl 11 extends into the notch, it tilts in the direction of the tension spring 13 under the action of the tension spring 13, so that the pawl 11 can avoid hindering the reverse rotation of the ratchet 10, thereby ensuring that the hose 4 can be recovered normally and stably. A pipe arranging device is arranged at the lower part of the frame 1, and the pipe arranging device is driven by the active pulley 27 and the driven pulley 26, so that the air pipe can be evenly arranged when pulled out and retracted, avoiding the entanglement and twisting of the pipeline, extending the service life of the air pipe, and making the inflation operation smoother and more efficient. An outer cover 29 is provided around and on the upper side of the frame 1, which has certain waterproof and dustproof functions, can adapt to the high humidity and high salt environment in the marine environment, reduce the impact of salt mist and dust on the mechanism, and thus extend the service life and reliability of the equipment.
