[0034] The terms “left,” “right,” “front,” “back,” “up,” and “down” mentioned in the following description are oriented in the viewing direction of the front view.

[0035] In some embodiments, please refer to the accompanying drawings of the specification. Figures 1-9 A pipe reeling device with a self-locking function comprises a base frame 1,

[0036] A tensioning force regulating and rewinding mechanism 2 is installed in the middle of the base frame 1;

[0037] The tension-adjusting winding mechanism 2 includes a winding assembly 21 for controlling the winding of the pipe, a diameter-changing assembly 22 for changing the tension of the pipe, and a synchronous drive assembly 23 for controlling the diameter-changing assembly 22 to change the diameter. The winding assembly 21 is installed at the rear end of the base frame 1 and connected to the diameter-changing assembly 22, and the diameter-changing assembly 22 is connected to the synchronous drive assembly 23.

[0038] A movable self-locking mechanism 3 is installed on the upper side of the rear end of the base frame 1 for continuously pressing the pipe to achieve tight winding;

[0039] In the present invention, when winding some pipes made of relatively hard materials, the end of the pipe is installed on the upper end of the reducing assembly 22, and the winding assembly 21 is started. The winding assembly 21 drives the reducing assembly 22 to rotate to wind the pipe; during the winding process, the movable self-locking mechanism 3 is started. The movable self-locking mechanism 3 can automatically lock the height during the winding process and automatically press the pipe horizontally as it moves. When the inner ring of the pipe is wound and the outer ring is wound, the movable self-locking mechanism 3 moves upward to make way for the inner ring of the pipe and continues to press the pipe as it moves. During the winding process, the synchronous driving assembly 23 works to expand the reducing assembly 22 outward, so that the inner ring of the pipe presses the outer ring of the pipe upward;

[0040] In the present invention, the cooperation of the winding assembly 21, the diameter-changing assembly 22 and the synchronous drive assembly 23 ensures that the inner pipe and the outer pipe fit tightly together during the winding process, thereby avoiding the sliding of the inner pipe due to insufficient tension, thereby improving the quality of pipe winding. The movable self-locking mechanism 3 can automatically lock the height during the winding process, and automatically press the pipe as it moves back and forth, so that some pipes made of harder materials fit tightly against the diameter-changing assembly, thereby avoiding the loosening of the pipe during winding, thereby further improving the quality of pipe winding.

The rotor of the conductive slip ring 213 is fixedly connected to the rotating shaft 212. The rear end of the baffle 214 is fixedly connected to the front end of the rotating shaft 212.

[0042] The reducing assembly 22 includes a fixed plate 221, a sliding groove 222, a sliding plate 223, a fixed plate 224, and a baffle 225. The rear end of the fixed plate 221 is fixedly connected to the front end of the baffle 214. The fixed plate 221 has a plurality of sliding grooves 222 formed therein, and the plurality of sliding grooves 222 are evenly distributed on the circumference of the fixed plate 221 at equal intervals. The sliding plate 223 is limitedly slidably connected to the fixed plate 221 through the sliding grooves 222. The front end of the fixed plate 224 is fixedly connected to the baffle 225 by bolts.

[0043] The synchronous drive assembly 23 includes a first servo motor 231, a small gear 232, a large gear 233, a slide 234 and a sliding rod 235.

[0044] The movable self-locking mechanism 3 includes a support plate 31, a second servo motor 32, a screw rod 33, a guide rod 34, a sliding sleeve plate 35, a pressure wheel 36, a slide rod 37, a cylinder 38 and a support block 39. The support block 39 is fixedly mounted on the upper side of the rear end of the base frame 1; the slide rod 37 is symmetrically fixedly mounted on the upper side of the inner part of the base frame 1; the cylinder 38 is fixedly mounted on the upper end of the support block 39, and the output shaft of the cylinder 38 is fixedly connected to the support plate 31, the support plate 31 is limited and slidably connected to the slide rod 37, and the second servo motor 32 is fixedly connected to the upper end of the support plate 31; the output shaft of the second servo motor 32 is fixedly connected to the upper end of the screw rod 33; the upper end of the guide rod 34 is fixedly connected to the lower end of the support plate 31; the upper left end of the sliding sleeve plate 35 is limited and slidably connected to the guide rod 34, and the upper right end of the sliding sleeve plate 35 is threadedly connected to the screw rod 33; the lower end of the sliding sleeve plate 35 is rotatably connected to the pressure wheel 36;

[0045] The pinch wheel 36 is provided with a pressure sensor. When the reading of the pressure sensor is within the set range, the pinch wheel 36 maintains the current height. When the inner pipe is wound and the outer pipe is wound, the reading of the pressure sensor exceeds the set range. At this time, the pressure sensor transmits a signal to the central control, which controls the second servo motor 32 to work. The second servo motor 32 drives the screw rod 33 to rotate, so that the sliding sleeve 35 drives the pinch wheel 36 to move upward. Until the reading of the pressure sensor returns to the set range, the second servo motor 32 stops working, and the height of the pinch wheel 36 is automatically locked, thereby maintaining the pinching effect on the pipe during winding.

[0046] In the present invention, the pipe is installed at the upper end of the fixed plate 224, and the motor 211 is started. The motor 211 drives the rotating shaft 212 to rotate, and the rotating shaft 212 drives the baffle plate 214 to rotate. The baffle plate 214 drives the fixed plate 221 to rotate, and the fixed plate 224 rotates together with the fixed plate 221 to reel the pipe; during the reeling process, the second servo motor 32 drives the screw rod 33 to rotate, so that the sliding sleeve 35 moves downward along the guide rod 34, so that the pressure wheel 36 is close to the pipe, realizing the automatic compression of the pipe; when the pipe moves forward, the cylinder 38 works to push the supporting plate 31, and the supporting plate 31 drives the pressure wheel 36 to move forward along the sliding rod 37 following the pipe; when the reeling of the inner ring pipe is completed When the outer ring pipe starts to be wound, the second servo motor 32 works to drive the screw rod 33 to rotate, so that the sliding sleeve 35 moves upward along the guide rod 34 to make way for the inner ring pipe. During the outer ring winding process, the cylinder 38 drives the supporting plate 31, so that the supporting plate 31 drives the pressing wheel 36 to move horizontally backward along the sliding rod 37 following the pipe. During the pipe winding process, the first servo motor 231 works to drive the small gear 232 to rotate, and the small gear 232 drives the large gear 233 to rotate, so that the sliding rod 235 slides along the sliding groove 234, and the sliding rod 235 drives the sliding plate 223 to move outward along the sliding groove 222. At this time, the fixed plate 224 moves outward together with the sliding plate 223, so that the inner ring pipe presses the outer ring pipe outward.

[0047] In the present invention, the small gear 232 and the large gear 233 cooperate to drive the fixed plate 224 to expand outward, so that during the winding process of the pipe, the inner circle of the pipe and the outer circle of the pipe are tightly fitted, avoiding the sliding of the inner layer of the pipe due to insufficient tension, thereby improving the quality of pipe winding; the cylinder 38 and the second servo motor 32 cooperate to make the clamping wheel 36 move back and forth with the pipe to maintain pressure on the pipe, so that some pipes with harder materials are close to the fixed plate 224, avoiding the loosening of the pipe during winding, and further improving the quality of pipe winding.
