The conveyor line carries a row of pallets and their cooling water pipes slowly forward. Workers are positioned on both sides of the conveyor line and manually assemble the pipes. At the end of the conveyor line, two additional workers are needed to lift the pallets carrying the cooling water pipes to a pre-set position. Needless to say, the workload and intensity for these two workers are extremely high, making it quite time-consuming and labor-intensive. Summary of the Invention

The device is arranged in a front-to-back orientation and connected to the top of the fixed frame via a pair of mounting seats. The rear end of the mounting shaft is connected to the output end of the second motor via a coupling. A pair of winding discs are keyed to the mounting shaft, and two steel wires are symmetrically connected to the center of the winding discs. The other end of the steel wires is connected to a fixed pulley, which is installed above the lifting mechanism. The fixed frame connects a U-shaped connecting frame between the two winding discs, and an X-shaped connecting plate is horizontally connected to the bottom of the connecting frame. A pair of fixed pulleys are symmetrically connected to the connecting plate on the left and right sides of each winding disc, and the steel wires on the same side overlap the upper side of the fixed pulleys.

[0006] Preferably, the lifting mechanism further includes a lifting frame and an installation tube. The lifting frame has a "U"-shaped structure. A pair of lifting frames are symmetrically distributed front and back. A fixed pulley on the same side is connected to the upper side of the lifting frame. A pair of installation tubes are symmetrically connected to the ends of the two lifting frames. A pair of double-headed cylinders are symmetrically distributed left and right. The double-headed cylinder on the same side is connected to the inner side of the installation tube via a pair of fixed plates. The ends of the two piston rods of each double-headed cylinder are connected to movable plates, and movable plates are vertically welded to the sides of the movable plates. The front and rear ends of the movable plates are welded with... A movable frame is slidably connected to the outside of the mounting tube.

[0010] Compared with the prior art, the present invention has the following advantages: 1. Automatically pick up the cooling water pipes. The AGV trolley transfers the device to the end of the cooling water pipe production line, and the pallets carrying the cooling water pipes are transported one by one to the bottom of the lifting mechanism. Then, the second motor drives the winding reel to rotate counterclockwise and release the steel wire on the winding reel, while the lifting mechanism descends synchronously. Based on the real-time measurement results of the photoelectric sensor, the lifting mechanism descends between the two pairs of handles on the lower pallet. Then, the piston rods of the two double-headed cylinders on both sides extend and drive the two pairs of clamping plates to extend laterally into the interior of the adjacent handles, and the clamping grooves on the clamping plates are laterally clamped into the side of the corresponding handle. Then, the second motor drives the winding reel to rotate clockwise and wind the steel wire on the winding reel, while the lifting mechanism, the pallet and the cooling water pipes on it rise synchronously, and the positioning rod on the lifting frame is inserted into the positioning cylinder on the connecting plate.

[0011] 2. Automatic removal of cooling water pipes. The AGV trolley moves the storage tray and its cooling water pipes to a preset position; then, the second motor drives the winding reel to rotate counterclockwise and release the steel wire on the winding reel, while the lifting mechanism, storage tray and its cooling water pipes descend synchronously until the storage tray is just in contact with the placement surface; then, the piston rods of the double-headed cylinders on both sides extend and drive the two pairs of clamping plates on the left and right to retract laterally to the side of the mounting pipe, and make the clamping grooves on the clamping plates move away from the side of the corresponding handle.

[0018] like Figures 1 to 7 As shown, a cooling water pipe transfer device includes an AGV trolley 10, a lifting mechanism 20, and a hoisting mechanism 30, wherein... The lifting mechanism 30 is located below the lifting mechanism 20 and includes a double-headed cylinder 304 and a clamping plate 312. The double-headed cylinder 304 is used to drive a pair of clamping plates 312 to clamp between a pair of handles 402 on the storage tray 40. The lifting mechanism 20 is located above the AGV trolley 10 and includes a first motor 206 and a second motor 209. The first motor 206 is used to drive the storage tray 40 and its cooling water pipe to deflect, and the second motor 209 is used to drive the storage tray 40 and its cooling water pipe to lift up and down. The AGV trolley 10 is used to move the storage tray 40 and its cooling water pipes.

[0019] In this embodiment, the lifting mechanism 20 further includes an annular guide rail 201, a movable plate 203, and a mounting shaft 210. The annular guide rail 201 is centrally connected to the upper side of the AGV trolley 10, and several guide rail sliders 202 are slidably connected on the annular guide rail 201. The movable plate 203 is horizontally connected to the upper side of all the guide rail sliders 202, and a gear ring 204 is coaxially mounted on the upper side of the movable plate 203. The motor 206 is vertically downward and mounted above the AGV trolley 10 through a fixing plate 205. A gear 207 is keyed to the output end of the motor 206, and the gear 207 meshes with the gear ring 204. A "𠃍"-shaped fixing frame 208 is centrally connected to the upper side of the movable plate 203. The motor 209 is horizontally forward and mounted on the upper part of the fixing frame 208. The shaft 210 is arranged front and back and connected to the top of the fixed frame 208 through a pair of mounting seats 211. The rear end of the mounting shaft 210 is connected to the output end of the second motor 209 through a coupling. A pair of winding discs 212 are keyed to the mounting shaft 210, and two steel wires 213 are symmetrically connected to the center of the winding discs 212. The other end of the steel wires 213 is connected to a fixed pulley 214, and the fixed pulley 214 is installed above the lifting mechanism 30. The fixed frame 208 connects a "U"-shaped connecting frame 215 between the two winding discs 212, and an "X"-shaped connecting plate 216 is horizontally connected to the bottom of the connecting frame 215. A pair of fixed pulleys 217 are symmetrically connected to the left and right sides of each winding disc 212 on the connecting plate 216. The steel wires 213 on the same side overlap the upper side of the fixed pulleys 217.

[0020] In this embodiment, the lifting mechanism 30 further includes a lifting frame 301 and an mounting tube 302. The lifting frame 301 has a "U"-shaped structure. A pair of lifting frames 301 are symmetrically distributed front and back. A fixed pulley 214 located on the same side is connected to the upper side of the lifting frame 301. A pair of mounting tubes 302 are symmetrically connected to the ends of the two lifting frames 301. A pair of double-headed cylinders 304 are symmetrically distributed left and right. The double-headed cylinders 304 located on the same side are connected to the inner side of the mounting tube 302 via a pair of fixing plates 303. Each piston rod of the double-headed cylinder 304 has a movable plate 305 connected to its end, and a movable plate 306 is vertically welded to the side of the movable plate 305. Movable frames 307 are welded to both the front and rear ends of the movable plate 306. The movable frame 307 is slidably connected to the outside of the mounting tube 302. A pair of racks 308 are symmetrically connected to the upper and lower sides of the movable plate 306. A pair of hinge shafts 309 are rotatably connected between the two movable frames 307 in the mounting tube 302. A hinge bar 310 is installed at both the upper and lower ends of the hinge shaft 309. A gear ring 311 is coaxially connected to the inner end of the hinge bar 310. The racks 308 on the same side mesh with the two gear rings 311. Two pairs of clamping plates 312 are provided and are symmetrically distributed on the left and right. Each pair of clamping plates 312 is correspondingly hinged to the outer ends of the front and rear pairs of hinge bars 310. The end face of the clamping plate 312 is provided with a semi-cylindrical clamping groove 312a. The clamping groove 312a cooperates with the handle 402 on the storage tray 40.

[0021] In this embodiment, a plurality of positioning cylinders 218 are evenly connected to the lower side of the connecting plate 216, and a plurality of positioning rods 219 are evenly connected to the upper side of the lifting frame 301. The positioning cylinders 218 and the positioning rods 219 correspond one-to-one and are coaxially arranged. By adding the above structure, the lifting mechanism 30 can be effectively confined below the connecting plate 216, thereby improving the stability of the storage tray 40 when it is transferred or deflected.

[0022] In this embodiment, a rubber sheet 313 is attached to the inner wall of the mounting plate 312 with the mounting groove 312a. By adding the rubber sheet 313, the friction and fit between the mounting groove 312a on the mounting plate 312 and the handle 402 can be improved.

[0023] In this embodiment, a plurality of mounting plates 314 are evenly connected to the outer side of the mounting tube 302, and a downward-facing photoelectric sensor 315 is vertically connected to the mounting plate 314. By adding the photoelectric sensor 315, the distance between the lifting mechanism 30 and the storage tray 40 directly below can be measured to determine whether the lifting mechanism 30 has descended to the preset height.

[0024] In this embodiment, the storage tray 40 consists of a tray 401 and two pairs of handles 402 on the left and right.

[0025] In practical applications, this cooling water pipe transfer device includes the following working steps: Step 1: The device is transferred to the end of the cooling water pipe production line by the AGV trolley 10, and the pallets 40 carrying cooling water pipes are transported one by one to the bottom of the lifting mechanism 30. Step 2: The motor 209 drives the winding disc 212 to rotate counterclockwise and releases the steel wire 213 on the winding disc 212. Meanwhile, the lifting mechanism 30 descends synchronously. Based on the real-time measurement results of the photoelectric sensor 315, the lifting mechanism 30 descends between the two pairs of handles 402 on the left and right sides of the storage tray 40 below. Step 3: The piston rods of the two double-headed cylinders 304 on both sides extend and drive the two pairs of clamping plates 312 to extend laterally into the interior of the adjacent handles 402, and the clamping grooves 312a on the clamping plates 312 are laterally clamped to the side of the corresponding handles 402. Step 4: The motor 209 drives the winding disc 212 to rotate clockwise and winds the steel wire 213 onto the winding disc 212. Meanwhile, the lifting mechanism 30, the storage tray 40 and its cooling water pipe rise synchronously, and the positioning rod 219 on the lifting frame 301 is inserted into the positioning cylinder 218 on the connecting plate 216. Step 5: The AGV trolley 10 transfers the storage tray 40 and its cooling water pipes to a preset location (e.g., another conveyor line or shelf). Step 6: The motor 209 drives the winding disc 212 to rotate counterclockwise and releases the steel wire 213 on the winding disc 212. Meanwhile, the lifting mechanism 30, the storage tray 40 and its cooling water pipes are lowered synchronously until the storage tray 40 is just in contact with the placement surface. Step 7: The piston rods of the two double-headed cylinders 304 on both sides extend and drive the two pairs of clamping plates 312 on the left and right to retract laterally to the side of the mounting tube 302, and make the clamping grooves 312a on the clamping plates 312 move laterally away from the side of the corresponding handles 402.

[0026] Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not exhaustive. All modifications within the scope of this invention or its equivalents are included in this invention.
