The front-to-back width inside the fixed track 42 and the movable track 43 is equal to the front-to-back width of the tray 39, and the distance between the left and right ends of the movable track 43 is equal to the distance between the two longitudinal plates of the bottom plate 1 and the left-right width of the tray 39, so that the movable track 43 can slide forward and backward inside the U-shaped opening of the bottom plate 1.

[0056] A longitudinal hydraulic cylinder 44 is provided at the front side of the moving rail 43, and the piston rod of the longitudinal hydraulic cylinder 44 is horizontally backward and fixedly connected to the front end surface of the moving rail 43. The moving rail 43 slides forward and backward inside the U-shaped opening of the bottom plate 1 by the extension and contraction of the longitudinal hydraulic cylinder 44. When the piston rod of the longitudinal hydraulic cylinder 44 is fully extended, the moving rail 43 drives the tray 39 to fully enter the U-shaped opening of the bottom plate 1; when the piston rod of the longitudinal hydraulic cylinder 44 is fully retracted, the moving rail 43 is connected to the fixed rails 42 on the left and right sides, so that the tray 39 can slide between the fixed rails 42 and the moving rail 43.

[0057] A push plate 45 is slidably disposed inside the left end opening of the fixed rail 42 on the left side. The push plate 45 is located in a vertical plane in the front-to-rear direction. A transverse push hydraulic cylinder 46 is disposed on the left side of the push plate 45. The piston rod of the transverse push hydraulic cylinder 46 is horizontally rightward and connected to the middle part of the left end surface of the push plate 45. The sliding of the push plate 45 inside the fixed rail 42 is achieved by the extension and retraction of the transverse push hydraulic cylinder 46.

[0058] A trumpet-shaped entrance 47 is provided at the left end of the front side wall of the left fixed track 42, and the entrance 47 is connected to the inside of the left fixed track 42. A trumpet-shaped exit 48 is provided at the right end of the front side wall of the right fixed track 42, and the exit 48 is connected to the inside of the right fixed track 42.

[0059] A limit assembly is provided in the middle of the left edge of the bottom plate 1 of the fixed track 42 on the right side, and the limit assembly includes a bracket 49, a limit block 50, a connecting rod 51, a limit spring 55, a limit cylinder 53, an iron block 52, and an electromagnetic suction 56. A through slot is provided in the middle of the left edge of the bottom plate 1 of the fixed track 42 on the right side, and a vertical limit block 50 is provided inside the through slot to slide along the vertical direction, and the left end face of the limit block 50 is flush with the left edge of the bottom plate 1 of the fixed track 42 on the right side. A vertical connecting rod 51 is fixedly arranged at the center of the lower end surface of the limiting block 50, and the lower end of the connecting rod 51 is inserted into the inside of the limiting cylinder 53. The limiting cylinder 53 is a circular cylindrical structure with an open upper end. The limiting cylinder 53 is fixedly arranged on the lower end surface of the fixed track 42 on the right side through the bracket 49; a separating ring 54 is fixedly arranged in the middle of the inner side of the limiting cylinder 53, and the lower end of the connecting rod 51 passes through the separating ring 54 and extends into the inner space of the limiting cylinder 53 below the separating ring 54. A cylindrical iron block 52 is fixedly arranged at the lower end of the connecting rod 51, and the outer diameter of the iron block 52 is larger than the inner diameter of the separating ring 54, so as to ensure that the connecting rod 51 will not fall out of the limiting cylinder 53. An electromagnetic suction 56 is fixedly arranged at the inner bottom surface of the limiting cylinder 53. A limiting spring 55 is sleeved on the outer side of the connecting rod 51, and the upper and lower ends of the limiting spring 55 are fixedly connected to the limiting block 50 and the separating ring 54 respectively.

[0060] The method of using the utility model is:

[0061] Step 1: The preparation state before the equipment is put into operation, that is, the two lifting hydraulic cylinders 36 are in a retracted state, so that the lifting box 3 rotates to the lowest position; the clutch hydraulic cylinder 27 is in a retracted state, so that the straight sections 18 of the two levers 17 away from the U-shaped section 19 are rotated to the side of the transverse section 4 of the lifting box 3, and the outer clutch blocks 15 on both sides are located inside the longitudinal section 5 of the lifting box 3; the longitudinal push hydraulic cylinder 44 is in a retracted state, so that the movable track 43 coincides with the fixed track 42; the transverse push hydraulic cylinder 46 is in a retracted state, so that the push plate 45 is located at the left end of the fixed track 42 on the left; the electromagnetic suction 56 is in a power-off state, and the electromagnetic suction 56 has no suction force, so that the iron block 52 contacts with the partition switching phase, and under the action of the rebound force of the limit spring 55, the limit block 50 is located at the highest point.

[0062] Step 2: Push the first tray 39 carrying the empty reel 12 into the left end of the fixed track 42 on the left through the entrance 47. Since the four corners of the tray 39 are provided with guide wheels 41, the guide wheels 41 are in contact with the trumpet-shaped entrance 47, ensuring that the first tray 39 can smoothly enter the fixed track 42 on the left. After the first tray 39 enters, ensure that the rear end of the first tray 39 is in contact with the rear inner wall of the fixed track 42 on the left. Then, the lateral pushing hydraulic cylinder 46 is controlled to extend a set length, so that the first pallet 39 is pushed to the right by the width of the left and right direction of a pallet 39; then, the second pallet 39 carrying the empty roll 12 is pushed in on the left side of the first pallet 39, and then the lateral pushing hydraulic cylinder 46 is controlled to extend a set length again, so that the first pallet 39 and the second pallet 39 are pushed to the right by the width of the left and right direction of a pallet 39 at the same time…and so on, until the first pallet 39 enters the interior of the movable track 43. Due to the obstruction of the rising limit block 50, the first pallet 39 can no longer continue to move to the right, and the pallet 39 is no longer pushed into the fixed track 42 on the left.

[0063] Step 3: Control the longitudinal hydraulic cylinder 44 to extend a set length, so that the moving track 43 drives the first tray 39 and the empty reel 12 on the tray 39 to enter the U-shaped opening of the bottom plate 1, ensuring that the moving track 43 contacts the inner side of the U-shaped opening of the bottom plate 1. At this time, the inner clutch blocks 13 at both ends of the fixed shaft of the empty reel 12 correspond to the outer clutch blocks 15 on both sides.

[0064] Step 4: Control the rotating motor 6 to start rotating slowly. The rotating motor 6 drives the transmission shaft 8 to rotate through the mutually meshing driving gear 7 and the driven gear 9. The transmission shaft 8 drives the driving shafts 10 on both sides to start rotating through the chain transmission mechanisms 11 at both ends. The driving shaft 10 drives the sliding sleeves 14 and the outer clutch block 15 on both sides to start rotating. Then control the piston rod of the clutch hydraulic cylinder 27 to extend. The clutch hydraulic cylinder 27 drives the left-side action rod 21 to slide to the left. The transmission rack 23 on the left-side action rod 21 drives the transmission gear 24 to rotate. The transmission gear 24 drives the transmission rack 23 on the right-side action rod 22 to slide to the right. Therefore, the left-side action rod 21 and the right-side action rod 22 slide horizontally to the left and right respectively at the same speed. The left action rod 21 drives the left first sliding column 26 to slide inside the left first sliding groove 25, so that the end of the straight section 18 of the left lever 17 away from the U-shaped section 19 rotates toward the left; the right action rod 22 drives the right first sliding column 26 to slide inside the right first sliding groove 25, so that the end of the straight section 18 of the right lever 17 away from the U-shaped section 19 rotates toward the right. Therefore, the U-shaped sections 19 of the two levers 17 rotate toward the direction of approaching each other, and the U-shaped sections 19 of the two levers 17 drive the two sliding sleeves 14 to slide on the drive shaft 10 toward the direction of approaching each other. The sliding sleeves 14 drive the two sets of outer clutch blocks 15 to slide toward the direction of approaching each other, so that the rotating outer clutch block 15 gradually docks with the inner clutch block 13 on the same side, and the outer cylindrical surface of the outer clutch block 15 after docking contacts the inner wall of the fixed groove at both ends of the fixed shaft of the winding drum 12.

[0065] Step 5: After the outer clutch block 15 is connected to the inner clutch block 13, the rotating motor 6 is controlled to stop rotating. The piston rods of the lifting cylinders on both sides begin to extend synchronously, causing the lifting box 3 to gradually rotate upward, and the reel 12 is separated from the tray 39. Then, one end of the hose is passed through the two vertical rollers 34 and fixed to one end of the fixed surface of the reel 12.

[0066] Step 6: Start the rotating motor 6 and the guide motor 28. The rotating motor 6 drives the transmission shaft 8 to rotate through the mutually meshing driving gear 7 and the driven gear 9. The transmission shaft 8 drives the driving shafts 10 on both sides to start rotating through the chain transmission mechanisms 11 at both ends. The driving shaft 10 drives the sliding sleeves 14 and the outer clutch block 15 on both sides to start rotating. The outer clutch block 15 drives the inner clutch block 13 to rotate, and the inner clutch block 13 drives the reel 12 to start rotating. At the same time, the guide motor 28 drives the screw 30 to rotate through the synchronous belt transmission mechanism 29. Since the moving seat 32 is screwed with the screw 30 and the moving seat 32 is slidably sleeved on the outer side of the guide rod 31, the moving seat 32 slides horizontally on the guide rod 31, thereby guiding the rubber hose through the horizontal roller 33 and the vertical roller 34, so that the rubber hose can be evenly wound on the reel 12. When the movable seat 32 contacts the limiting ring 35 on one side of the guide rod 31, the guide motor 28 starts to rotate in the reverse direction, causing the movable seat 32 to slide in the reverse direction, so that the hose can be wound on the reel 12 along the other direction until the hose is evenly wound on the reel 12.

[0067] Step 7: After the hose on the first reel 12 is wound, the hose is cut off, and then the guide motor 28 and the rotating motor 6 are stopped, and the lifting hydraulic cylinder 36 is retracted to rotate the lifting box 3 downward until the reel 12 contacts the tray 39, and the reel 12 is stuck in the arc groove 40 on the upper end surface of the tray 39; then the piston rod of the clutch hydraulic cylinder 27 is controlled to retract, so that the left action rod 21 slides to the right and the right action rod 22 slides to the left, so that the U-shaped sections 19 of the two shifting rods 17 rotate in directions away from each other, and the U-shaped sections 19 of the two shifting rods 17 drive the two sliding sleeves 14 to slide on the driving shaft 10 in the direction of the principle, and the sliding sleeves 14 drive the two groups of outer clutch blocks 15 to slide in the direction away from each other, so that the outer clutch block 15 is disengaged from the inner clutch block 13 on the same side.

[0068] Step 8: Control the piston rod of the longitudinal push hydraulic cylinder 44 to retract, so that the moving rail 43 drives the first pallet 39 and the pallet 39 wrapped with the hose to move toward the front side until the moving rail 43 is connected with the fixed rail 42.

[0069] Step 9: Control the electromagnetic suction 56 to be energized, so that the electromagnetic suction 56 generates magnetic attraction, and the electromagnetic suction 56 attracts the push block to slide downward, the limit spring 55 is compressed, and the limit block 50 slides downward under the drive of the connecting rod 51, and the limit block 50 is out of contact with the right end face of the first tray 39, and the limit block 50 no longer blocks the first tray 39. Then control the piston rod of the lateral push hydraulic cylinder 46 to extend, thereby pushing all trays 39 on all tracks to slide to the right. At the same time, control the electromagnetic suction 56 to be de-energized, so that the limit block 50 rises again under the action of the rebound force of the limit spring 55, and the upper end face of the limit block 50 after rising keeps sliding contact with the lower end face of the first tray 39. When the first tray 39 slides to the right until the limit groove 57 thereon corresponds to the limit block 50, the limit block 50 extends into the limit groove 57 of the first tray 39 under the action of the rebound force of the limit spring 55. At this time, the rising limit block 50 blocks and limits the second tray 39. At this time, the second tray 39 completely enters the movable track 43.

[0070] Step 10: Push another tray 39 carrying an empty roll 12 from the entrance 47 of the fixed track 42 on the left, and then repeat the above steps 3 to 9, so that the empty roll 12 on the second tray 39 is also wrapped with a hose, and then pushed from the movable track 43 to the fixed track 42 on the right.

[0071] Step 11: When the reel 12 wound with the hose is pushed to the outlet 48 of the fixed track 42 on the right side, the tray 39 is pulled outward from the outlet 48 to the outside of the fixed track 42 .
