[0025] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0026] like Figures 1-8As shown, the automatic loading and unloading device for color steel plates of the present invention includes a frame, a rotating assembly, a lifting assembly, and a transverse assembly. The frame includes two sets of columns 1 arranged side by side, and a longitudinal horizontal fixed beam is fixedly connected to the middle of each set of columns 1. The rotating assembly is set on the two longitudinal horizontal fixed beams and can rotate on the two longitudinal horizontal fixed beams to support the color steel plate 10 before it moves downward. The lifting assembly is installed on the two sets of columns 1 and can move up and down along the columns 1 to drive the color steel plate 10 to move downward. The transverse assembly is set above the lifting assembly and is used to clamp the color steel plate 10.

[0027] like Figure 1 and Figure 2 As shown, the frame includes six columns 1, with three columns 1 forming a group. Two groups of columns 1 are arranged opposite each other. A fixed crossbeam 4 is fixed between the tops of the two middle columns 1. Two longitudinal horizontal fixed crossbeams are symmetrically installed in the middle of the two groups of columns 1. The fixed crossbeam 4 is perpendicular to the two longitudinal horizontal fixed crossbeams. The two longitudinal horizontal fixed crossbeams include longitudinal horizontal fixed crossbeam one 2 and longitudinal horizontal fixed crossbeam two 3. Longitudinal horizontal fixed crossbeam one 2 is L-shaped.

[0028] The rotating assembly includes a guide rail 20 located on a longitudinal horizontal fixed beam 2. The guide rail 20 is arranged along the length of the longitudinal horizontal fixed beam 2. An intermittent rack plate 21 is slidably arranged on the guide rail 20. Grooved rollers 22 are installed at the bottom of both ends of the intermittent rack plate 21. The grooved rollers 22 cooperate with the guide rail 20 and can move the intermittent rack plate 21 along the guide rail 20. A hydraulic cylinder 23 is connected to the middle of one end of the intermittent rack plate 21 through a hinge. The piston rod of the hydraulic cylinder 23 drives the intermittent rack plate 21 to move along the guide rail 20 through the hinge.

[0029] The intermittent rack plate 21 has three segments of teeth 24 in the middle, with the teeth 24 facing the longitudinal horizontal fixed crossbeam 2 3. There are two sliding through holes 25 between the three segments of teeth 24, which cooperate with the guide pins 26 installed on the side of the longitudinal horizontal fixed crossbeam 2 2. When the intermittent rack plate 21 moves along the guide rail 20, the guide pins 26 move in the sliding through holes 25.

[0030] Both ends and the middle of the longitudinal horizontal fixed crossbeam 2 are equipped with half gears 27 that mesh with the gear teeth 24 of the intermittent rack plate 21 via rotating shafts 28. The half gears 27 have teeth along three-quarters of the circumference, and a rotating hole runs through the middle of the half gears 27. The half gears 27 are mounted on the longitudinal horizontal fixed crossbeam 22 via rotating shafts 28.

[0031] The other end of each of the three half-gears 27 is fixedly connected to a rotating roller 8, and the other end of the rotating roller 8 is attached to the longitudinal horizontal fixed crossbeam 2 3. When the hydraulic cylinder 23 moves along the guide rail 20 with the intermittent rack plate 21, the half-gears 27 rotate relative to the gear teeth 24 on the intermittent rack plate 21, and the rotating roller 8 can rotate with the half-gears 27. During the rotation, the rotating roller 8 rotates between the longitudinal horizontal fixed crossbeam 2 2 and the longitudinal horizontal fixed crossbeam 2 3, and the half-gears 27 drive the rotating roller 8 to rotate within the 0-135° angle range.

[0032] Preferably, a stop pin 31 is installed at the free end of the rotating idler roller 8, and a limit pin 29 is provided at the position corresponding to the half gear 27 on the longitudinal horizontal fixed crossbeam 2. When the rotating idler roller 8 rotates onto the longitudinal horizontal fixed crossbeam 3, the stop pin 31 cooperates with the limit pin 29, and the limit pin 29 is used to limit the rotating idler roller 8.

[0033] The lifting assembly includes three lifting beams 5 installed in parallel on six columns 1. All six columns 1 are I-beams. Rollers 18 are provided at both ends of the three lifting beams 5. The rollers 18 roll along the inner groove of the column 1. The three lifting beams 5 are perpendicular to two longitudinal horizontal fixed beams. The three lifting beams 5 include lifting beam one 51, lifting beam two 52 and lifting beam three 53 arranged in sequence. Lifting beam two 52 is connected to the fixed beam 4 by steel wire rope 9. Two guide rails two are provided at both ends of the upper surface of the three lifting beams 5. A limit switch is provided at the end of the guide rail two near the middle.

[0034] The three lifting beams 5 are connected by a longitudinal lifting beam 54. The longitudinal lifting beam 54 is bolted to the middle of the lower surface of the three lifting beams 5. A wire rope lifting ring 19 is also installed between the longitudinal lifting beam 54 and the second lifting beam 52.

[0035] The lateral movement assembly includes two transverse moving beams 6 that cooperate with guide rails 2 on the three lifting beams 5. The transverse moving beams 6 have guide rail grooves at the positions where they cooperate with guide rails 2. The transverse moving beams 6 move laterally on the lifting beams 5 along the guide rails 2 through the guide rail grooves, and move up and down with the lifting beams 5.

[0036] Multiple threaded holes 30 are provided on one side of the two transverse moving beams 6 where they intersect with the three lifting beams 5. Each transverse moving beam 6 is connected to three double-claw tie rod plates 7 through the threaded holes 30. The double-claw tie rod plates 7 on the two transverse moving beams 6 are arranged opposite each other in pairs, and the double-claw tie rod plates 7 can move with the transverse moving beams 6.

[0037] A two-way dual-segment gear screw 16 is installed on the second lifting beam 52 along the length of the lifting beam 5. The two ends of the two-way dual-segment gear screw 16 are connected to the transverse moving beam 6 through threaded holes 30. Both ends of the two-way dual-segment gear screw 16 are mounted on the second lifting beam 52 through gear screw supports 17. When the two-way dual-segment gear screw 16 rotates, it can drive the two transverse moving beams 6 to move simultaneously towards each other or away from each other along the second lifting beam 52.

[0038] The middle position of the bidirectional two-stage gear screw 16 located on the second lifting beam 52 is connected to the output shaft of the gear shaft motor 12 set on the second lifting beam 52 through the transmission gear pair 13. The rotation of the gear shaft motor 12 drives the bidirectional two-stage gear screw 16 to rotate, and the rotation of the bidirectional two-stage gear screw 16 drives the transverse moving beam 6 to move.

[0039] A lifting motor 14 is installed on the fixed crossbeam 4. The output shaft of the lifting motor 14 is connected to the wire rope 9. The wire rope 9 passes through the wire rope drum 15 and connects to the second lifting crossbeam 52. The wire rope 9 and the second lifting crossbeam 52 are connected by a wire rope lifting ring 19. When the lifting motor 14 starts, it causes the wire rope 9 to extend or retract. The extension or retraction of the wire rope 9 can cause the second lifting crossbeam 52 to descend or rise, thereby causing the transverse moving beam 6 and the double claw tie rod plate 7 to descend or rise. The multiple double claw tie rod plates 7 can clamp the color steel plate 10, thereby causing the color steel plate 10 to descend.

[0040] A storage trolley 11 is placed on the ground inside column 1, which can move along the track on the ground.

[0041] The working process of the automatic loading and unloading device for color steel plates of the present invention is as follows:

[0042] Initially, one end of the rotating roller 8 rests on the longitudinal horizontal fixed beam 3, and the two claws of the double-claw pull plate 7 stop directly below the rotating roller 8. When the color steel plate 10 moves to the upper surface of the rotating roller 8 spanning the two longitudinal horizontal fixed beams, the gear shaft motor 12 drives the bidirectional two-stage gear screw 16 to rotate in the forward direction, causing the two transverse moving beams 6 to move towards the middle, and the two claws of the double-claw pull plate 7 extend to the lower surface of the color steel plate 10 to support it. The lifting motor 14 drives the three lifting beams 5 to rise through the wire rope 9, lifting the color steel plate 10 to a certain height. The hydraulic cylinder 23 drives the intermittent rack plate 21 to move along the guide rail 20 on the longitudinal horizontal fixed beam 2, causing the rotating roller 8 to rotate 90° and stop on the upper surface of the longitudinal horizontal fixed beam 2. The lifting motor 14 drives the three lifting beams 5 to descend through the wire rope 9, placing the color steel plate 10 onto the storage trolley 11 parked on the ground. The gear shaft motor 12 drives the bidirectional two-stage gear screw 16 to rotate in the reverse direction, causing the two transverse moving beams 6 to move to both sides, and the two claws of the double-claw tie plate 7 to move away from the lower surface of the color steel plate 10. The hydraulic cylinder 23 drives the intermittent rack plate 21 to move in the reverse direction along the guide rail 20 on the longitudinal horizontal fixed crossbeam 2, causing the rotating roller 8 to rotate 90° in the reverse direction and span across the upper surface of the two longitudinal horizontal fixed crossbeams. After the next section of color steel plate 10 moves over, the above actions are repeated. When the color steel plate 10 reaches the predetermined height, the storage trolley 11 automatically moves away from the current position, and the subsequent storage trolley 11 automatically stops at the corresponding position, waiting to load the color steel plate. This cycle repeats 10 times to complete the automatic loading and unloading of the color steel plate.
