Specific embodiments

[0022] As shown in the appendix Figure 1-6 shown

[0023] The hoisting device for the polymer precast irrigation canal is composed of a base frame 1, a movable frame, a horizontal push hydraulic cylinder 2, a left roller assembly, a right roller assembly and a jaw mechanism. The cross-section of the base frame 1 is a "冂"-shaped frame, and slide rails 3 are symmetrically and fixedly installed at the top of the base frame 1, and a movable frame is slidably installed on the slide rails 3.

[0024] The movable frame includes a frame body 4. The frame body 4 is in a rectangular frame shape. One end of the frame body 4 is symmetrically and fixedly installed with mounting seats. On each mounting seat, a driving shaft is movably installed through symmetrically arranged bearings. An active sliding roller 5 is fixedly installed on the driving shaft. A drive motor 6 is installed on the frame body 4 corresponding to the active sliding roller 5. The transmission shaft of the drive motor 6 is fixedly connected to the driving shaft. When in use, the driving shaft is driven to rotate by the transmission shaft of the drive motor 6, and the driving shaft drives the active sliding roller 5 to rotate synchronously.

[0025] The other end of the frame body 4 is symmetrically and fixedly installed with mounting seats. On each mounting seat, a driven shaft is movably installed through symmetrically arranged bearings. A driven sliding roller 7 is fixedly installed on the driven shaft.

[0026] The active sliding roller 5 and the driven sliding roller 7 are both in the shape of groove wheels, and the active sliding roller 5 and the driven sliding roller 7 are respectively slidably connected with the slide rail 3. When in use, the active sliding roller 5 and the driven sliding roller 7 in the shape of groove wheels can form a guide limit on the slide rail 3, so that the active sliding roller 5 and the driven sliding roller 7 roll along the axial direction of the slide rail 3.

[0027] A horizontal push hydraulic cylinder 2 is fixedly mounted on the movable frame via a cylinder mounting seat 26 , and a push rod 8 is fixedly mounted on the piston rod of the horizontal push hydraulic cylinder 2 . When in use, the push rod 8 is driven by the piston rod of the horizontal push hydraulic cylinder 2 to move horizontally.

[0028] A right roller assembly is installed on the movable frame at one end of the transverse push hydraulic cylinder 2, and the right roller assembly includes a first assembly plate 9, which is symmetrically fixedly installed on the movable frame, and a first roller shaft 10 is movably installed on the first assembly plate 9 through a bearing, and a first sprocket 11 is symmetrically fixedly installed on the first roller shaft 10, and a second sprocket 12 is fixedly installed on the first roller shaft 10 outside the first sprocket 11.

[0029] A left roller assembly is mounted on the movable frame at the other end of the transverse push hydraulic cylinder 2. The left roller assembly includes a second assembly plate 13, which is symmetrically fixedly mounted on the movable frame. A second roller shaft 14 is movably mounted on the second assembly plate 13 through a bearing, and a third sprocket 15 is symmetrically fixedly mounted on the second roller shaft 14.

[0030] A claw mechanism is arranged below the horizontal push hydraulic cylinder 2, and the claw mechanism includes a support plate 16. The support plate 16 is a long rectangular plate. A limit seat 17 is symmetrically arranged at the bottom of the support plate 16. An open slide groove 18 is arranged in the limit seat 17. The cross-section of the limit seat 17 is in the shape of an inverted "concave". A connecting block 19 is slidably installed in the slide groove 18. The connecting block 19 is a long rectangular body. Rollers 20 are symmetrically and movably installed on both sides of the connecting block 19 through a connecting axis. The rollers 20 are slidably connected with the slide groove 18 of the limit seat 17. A clamping jaw 22 and a cylinder 21 are fixedly installed on the support plate 16 on one side of the connecting block 19, and the piston rods of the clamping jaw 22 and the cylinder 21 are fixedly connected to the connecting block 19.

[0031] The bottom end of the connecting block 19 extends to the outside of the limiting seat 17, and a clamping claw 22 is fixedly installed on the connecting block 19 extending to the outside of the limiting seat 17. The cross-section of the clamping claw 22 is in the shape of a semicircular arc. When in use, the clamping claw 22 with a semicircular arc cross-section cooperates with the inner cavity of the polymer prefabricated irrigation channel 27 to reduce the shaking of the polymer prefabricated irrigation channel 27 during transportation.

[0032] Wing plates 23 are symmetrically arranged at both ends of the support plate 16. The push rod 8 is fixedly connected to the wing plate 23 at the right end of the support plate 16 through a symmetrically arranged first chain 24 and the first sprocket 11 of the right roller assembly. The push rod 8 is fixedly connected to the wing plate 23 at the left end of the support plate 16 through a symmetrically arranged second chain 25 and the second sprocket 12 of the right roller assembly and the third sprocket 15 of the left roller assembly.

[0033] When the lifting device of the polymer prefabricated irrigation channel is used, the lifting device is first set above the cutting table passing through the cutting machine, and the drive motor 6 is started. The drive motor 6 drives the movable frame to move along the slide rail 3 to just above the polymer prefabricated irrigation channel 27 that has been cut. The drive motor 6 is stopped, and the piston rod of the horizontal push hydraulic cylinder 2 is extended. The piston rod drives the push rod 8 to move to the right, and the push rod 8 drives the first chain 24 and the second chain 25 to move to the right. Under the cooperation of the first sprocket 11, the second sprocket 12 and the third sprocket 15, the support plate 16 of the claw mechanism and the chain between the sprockets are synchronously and gradually lengthened, thereby driving the support plate 16 to move downward.

[0034] When the clamping jaws 22 of the support plate 16 correspond to the inner cavity of the polymer prefabricated irrigation channel 27, the piston rod of the horizontal push hydraulic cylinder 2 is stopped, and the piston rod of the clamping jaw 22 cylinder 21 is started to retract, so that the piston rods of the clamping jaws 22 cylinder 21 at both ends drive the connecting rods and the clamping jaws 22 on both sides of the support plate 16 to move closer to each other. When the clamping jaws 22 enter the inner cavity of the polymer prefabricated irrigation channel 27, the clamping jaws 22 clamp the polymer prefabricated irrigation channel 27, the piston rod of the clamping jaw 22 cylinder 21 is stopped from retracting, and the piston rod of the horizontal push hydraulic cylinder 2 is started to retract, and the piston rod drives the push rod 8 to move left, and the push rod 8 pulls the first chain 24 and the second chain 25 to move left. Under the cooperation of the first sprocket 11, the second sprocket 12 and the third sprocket 15, the chain between the support plate 16 of the claw mechanism and the sprocket is synchronously shortened gradually, thereby driving the claw mechanism and the polymer prefabricated irrigation channel 27 to move upward.

[0035] Start the drive motor 6, and the drive motor 6 drives the movable frame to move along the slide rail 3 to the stacking area of ​​the polymer prefabricated irrigation channel 27, and stack the polymer prefabricated irrigation channel 27 in sequence. Repeat the above operation to circulate the moving and stacking operations of the polymer prefabricated irrigation channel 27. The lifting device of the polymer prefabricated irrigation channel effectively reduces the manual labor and improves the efficiency of the moving work, thereby solving the safety hazard problem of easily pinching the fingers of workers when stacking the existing polymer prefabricated irrigation channels 27.
