[0032] Embodiment A weft disc hoisting device and use method for a steel skeleton plastic pipe production line

[0033] This embodiment discloses a weft disc hoisting device for a steel skeleton plastic pipe production line. Figure 1As shown, it includes a connecting rod 1, which is slidably connected to the hanging rod 2. The two ends of the connecting rod 1 are respectively hinged to the clamping arms 3, and the two sides of the hanging rod 2 are respectively hinged to one end of the control arm 4. Each control arm 4 is connected to the corresponding clamping arm 3 away from the end of the hanging rod 2. Each clamping arm 3 is rotated away from the end of the connecting rod 1 to connect the arc disk 5. The two arc disks 5 clamp the weft disk. The arc disk 5 is connected to the driving motor 6 for driving the arc disk 5 to rotate. The driving motor 6 is a servo motor. The output shaft of the servo motor is connected to the arc disk 5. The servo motor is connected to the clamping arm 3. The servo motor can be one. When there is one servo motor, the output shaft of the servo motor is connected to an arc disk 5. The servo motor rotates and drives The arc disk 5 drives the weft disk and the other arc disk 5 to rotate; there can also be two servo motors, and the output shafts of the two servo motors are respectively connected to the two arc disks 5, and the two servo motors respectively drive the corresponding arc disk 5 to rotate and drive the weft disk to rotate in the same direction. The driving motor 6 can also be an electric motor, and the motor transmission is connected to the reducer, and the reducer transmission is connected to the arc disk to rotate. The use of mechanical rotation improves safety; the method for using the weft disk lifting device of the steel skeleton plastic pipe production line includes an overhead crane, the overhead crane is connected to the controller through electric wires, the hook of the overhead crane is connected to the hanging rod 2, and the driving motor 6 is connected to the controller through electric wires. When in use, first, the driving motor is driven by the controller The machine 6 rotates to place the arc disk 5 horizontally. After that, the operator drives the two clamping arms 3 to drive the arc disk 5 to open and sleeve on the weft disk, and makes the two arc disks 5 clamp the weft disk. Then, the controller is used to drive the overhead crane to lift the hanging rod 2. Since the weft disk has a certain weight, the hanging rod 2 rises and drives the two control arms 4 to rise away from the clamping arms 3. That is, the distance between the two control arms 4 is shortened, and the distance between the clamping arms 3 connected to the two control arms 4 is shortened. The shortened distance between the two clamping arms 3 shortens the distance between the arc disks 5 connected to the two clamping arms 3. The shortened distance between the two arc disks 5 makes the two arc disks 5 clamp the weft disk, so that the overhead crane drives the weft disk to rise. When raised, the weft disk is placed vertically. Then, when the weft disk is close to the weft installation axis, the controller is used to rotate the drive motor 6 to place the weft disk horizontally. Then, the controller is used to control the overhead crane to place the weft disk in the center of the weft installation circle. Finally, the operator controls the clamping arm 3 to drive the arc disk 5 away from the weft disk, and controls the overhead crane to drive the weft disk lifting device of the steel skeleton plastic pipe production line away from the weft disk through the controller to complete the lifting of the weft disk. The lifting, rotation and placement of the weft disk are all controlled by the controller, so that the operator is away from the weft disk lifting device of the steel skeleton plastic pipe production line, thereby improving safety. Therefore, the advantage of this embodiment is that the above-mentioned setting is adopted to improve safety.

[0034] A preferred structure of the arc-shaped disk 5 in this embodiment is as follows: Figure 2 、 Figure 3As shown, the arcuate disc 5 includes an upper chuck 501, a lower chuck 502 and a connecting plate 503. The two ends of the connecting plate 503 are respectively connected to the corresponding upper chuck 501 and the lower chuck 502. The connecting plate 503 is rotatably connected to the corresponding clamping arm 3. The arcuate disc 5 also includes a plurality of reinforcing ribs 504. The two ends of the reinforcing ribs 504 are respectively connected to the opposite ends of the upper chuck 501 and the lower chuck 502. The plurality of reinforcing ribs 504 are arranged at intervals along the arc of the upper chuck 501. The arrangement of the reinforcing ribs 504 is as follows: The arrangement improves the fixation of the upper chuck 501 and the lower chuck 502; the connecting plate 503 and the plurality of reinforcing ribs 504 are close to the outer walls of the upper chuck 501 and the lower chuck 502. When the arc-shaped disk 5 is in the working position, the opposite ends of the upper chuck 501 and the lower chuck 502 clamp the two ends of the weft disk, and the connecting plate 503 and / or the reinforcing ribs 504 abut against the side walls of the weft disk. This arrangement makes the weft disk located between the upper chuck 501, the lower chuck 502, the connecting plate 503 and the reinforcing ribs 504. The stability of the weft disk is improved and the safety is improved; the upper chuck 501 is provided with a clamping mechanism 7, which is used to clamp or loosen the weft disk, and the clamping mechanism 7 includes a first electric hydraulic push rod 701 and a clamping block 702, the fixed end of the first electric hydraulic push rod 701 is connected to the upper chuck 501, the extended end of the first electric hydraulic push rod 701 is slidably connected to the upper chuck 501, the extended end of the first electric hydraulic push rod 701 is connected to the clamping block 702, the clamping block 702 is located between the upper chuck 501 and the lower chuck 02, the first electric hydraulic push rod 701 extends or contracts to drive the clamping block 702 close to or away from the weft disk, the first electric hydraulic push rod 701 is electrically connected to the controller, so that the clamping block 702 clamps or loosens the weft disk to realize mechanical automation, this arrangement increases the connection stability between the weft disk and the upper chuck 501 and the lower chuck 502; further improves safety; therefore, the advantage of this embodiment is that the above arrangement is adopted to improve safety.

The extension or contraction of the second electric hydraulic push rod 8 is used to drive the hanging rod 2 to slide back and forth along the connecting rod 1 so that the clamping arm 3 clamps or opens the weft disk. The second electric hydraulic push rod 8 is electrically connected to the controller. The controller extends the second electric hydraulic push rod 8 to make the hanging rod 2 rise along the connecting rod 1. The rise of the hanging rod 2 drives the control arm 4 to rise away from the end of the clamping arm 3, so that the distance between the two clamping arms 3 is shortened. The distance between the two clamping arms 3 is shortened, so that the arc disk 5 connected to the two clamping arms 3 clamps the weft disk, and vice versa. In other words, the controller contracts the second electric hydraulic push rod 8, causing the arc disk 5 to open (loosen) away from the weft disk. When in use, the connecting rod 1 is connected to the overhead crane. The setting of the second electric hydraulic push rod 8 enables the clamping arm 3 to drive the arc disk 5 to clamp or open the weft disk to realize mechanical automation, avoiding manual operation to clamp or open the clamping arm 3 to clamp or open the weft disk, thereby improving safety. This setting enables the clamping or opening of the weft disk to be operated by the controller, realizing mechanical automation, keeping the operator away from the weft disk lifting device of the steel skeleton plastic pipe production line, thereby improving safety. Therefore, the advantage of this embodiment is that the above-mentioned setting improves safety.
