DETAILED DESCRIPTION

[0035] like Figure 1 As shown, a stacker cargo platform carrying a special trolley includes a hoist frame 1 and a lifting platform 2 slidably assembled on the hoist frame 1. The lifting platform 2 can slide up and down along the hoist frame 1. Specifically, the lifting platform 2 can be driven to move by a winch in conjunction with steel cables and other structures. Since it is a common equipment in the mechanical field, the operation process and principle of the structures such as the hoist frame 1 and the lifting platform 2 will not be described in detail here.

[0036] Combine Figure 2-Figure 7 As shown, the top surface of the lifting platform 2 is slidably equipped with a support frame 14, and the top surface of the support frame 14 is slidably equipped with a slide 10, which can realize the secondary transportation of the slide 10. Figure 3 As shown, a frame 8 for supporting the tubular workpiece 4 is slidably provided on the support frame 14, and a pushing assembly that cooperates with the frame 8 is connected to the slide 10. Through this structure, the slide 10 can push the frame 8 on the horizontal plane during the movement, so that the frame 8 and the workpiece 4 on the frame 8 can be pushed into the spray room 5 for spraying operation.

[0037] Furthermore, the pushing assembly includes a short rod 6 arranged above the slide 10 and capable of rotating relative to the slide 10, and at least one set of main splints 601 is fixed at the end position of the short rod 6. Figure 3-Figure 4 As shown, a plurality of positioning bars 801 cooperating with the main plates 601 are fixedly provided on the bottom surface of the frame 8, and the positioning bars 801 are evenly distributed in a linear array. When the short rod 6 drives the main plates 601 to rotate synchronously so that the two main plates 601 are located on both sides of the positioning bars 801, the sliding of the slide plate 10 can push the frame 8 to move along the support frame 14, thereby facilitating the pushing of the frame 8 into the spray booth 5 for spraying operations.

[0038] In actual use, main rails 12 are fixedly installed on both sides of the top surface of the lifting platform 2, and the support frame 14 slides on the main rails 12. In order to drive the support frame 14 to move relative to the lifting platform 2, a main rack 15 can be fixedly installed at the side position of the lifting platform 2, and the outer side of the main rack 15 is engaged with a driving gear. Specifically, a first motor is installed on the support frame 14, and the output shaft of the first motor is connected to the above-mentioned driving gear, so that the first motor can drive the driving gear to rotate, and then the cooperation between the driving gear and the main rack 15 causes the support frame 14 to slide along the lifting platform 2; similarly, two main racks 15 are fixed on both sides of the support frame 14 and at the top position. A secondary guide rail 11 is provided, and the skateboard 10 slides on the secondary guide rail 11, and secondary racks 13 are fixedly installed on both sides of the inner bottom surface of the support frame 14. A second motor is fixedly installed on the bottom surface of the skateboard 10, and the output shaft of the second motor is connected to the driving gear 16. The driving gear 16 is engaged with the secondary rack 13. Specifically, the engagement of the main rack 15 with the driving gear can drive the support frame 14 to slide along the lifting platform 2, and the cooperation of the secondary rack 13 and the driving gear 16 can drive the skateboard 10 to slide along the support frame 14, and then the frame 8 is sent into the spray booth 5 through the cooperation of the main splint 601 and the positioning bar 801.

[0039] Combine Figure 1-Figure 3 、 Figure 6-Figure 7As shown, support rollers 3 are installed on both sides of the top of the frame 8. Specifically, bosses 20 are provided at both ends of the support roller 3, and the bosses 20 are fixedly connected to the frame 8. A round shaft is fixedly installed on the end of the support roller 3. The round shaft passes through the boss 20 and rotates with the boss 20 through a bearing, and a turntable 7 is provided on one side of the boss 20. The above-mentioned round shaft passes through one end of the boss 20 and is fixedly connected to the turntable 7, and the position where the round shaft and the turntable 7 are fixed is located at the center of the turntable 7. Two insertion rods 701 are fixedly provided on the side of the turntable 7 away from the support roller 3. The two insertion rods 701 are symmetrically arranged about the center of the turntable 7. In actual use, a chuck 501 is rotatably connected in the spray room 5 and near the rear, and the chuck 501 is provided with a connection with the upper The socket that cooperates with the insertion rod 701 has an inner diameter larger than the outer diameter of the insertion rod 701. The socket can be a circular or arc-shaped structure. In actual use, the frame 8 can be pushed into the spray room 5 through the cooperation of the main splint 601 and the positioning bar 801. When the insertion rod 701 passes through the socket on the chuck 501, the chuck 501 can drive the turntable 7 and the support roller 3 to rotate during the rotation process, thereby driving the workpiece 4 between the two support rollers 3 to rotate, and then the surface of the workpiece 4 can be evenly sprayed. In this way, the frame 8 is always in the horizontal plane during the pushing process, which is conducive to the docking of the insertion rod 701 and the socket. Compared with the traditional telescopic fork structure, this method is more conducive to the cooperation between the insertion rod 701 and the socket.

[0040] like Figure 3-Figure 14 As shown, the cross section of the short rod 6 can be circular, and the main plate 601 is fixed to the outer wall of the short rod 6. Although this structure can push the frame 8, during the process of adjusting the position of the skateboard 10, the short rod 6 needs to be rotated to disengage the main plate 601 from the positioning bar 801. At this time, the frame 8 as a whole lacks the corresponding limit, making the frame 8 in a relatively unstable state. Based on this, the shape of the short rod 6 is adjusted. Specifically, referring to Figure 9 As shown, the cross section of the short rod 6 can be semicircular, and two sets of main splints 601 are fixedly connected to the outer peripheral wall of the short rod 6 along its circumferential direction. The number of each set of main splints 601 is set to two, and the two main splints 601 are distributed on the same straight line. The two sets of main splints 601 are vertically distributed. When the skateboard 10 drives the short rod 6 to move back and forth, the main splints 601 can cooperate with the positioning bar 801, thereby driving the frame 8 to move;

[0041] Furthermore, a long rod 17 is provided at the short rod 6, and the long rod 17 is connected to the support frame 14. The cross section of the long rod 17 is also semicircular, and the long rod 17 is fitted with the short rod 6 so that the short rod 6 can slide along the axis direction of the long rod 17. When the short rod 6 and the long rod 17 are fitted together, they can form a complete cylindrical structure. Figure 8-Figure 9 、 Figure 12 As shown, two sets of auxiliary splints 1701 are fixedly provided on the outer peripheral wall of the long rod 17 and at the end position. The two sets of auxiliary splints 1701 are arranged along the circumference of the long rod 17. The number of each set of auxiliary splints 1701 is set to two and distributed on the same straight line, similar to the distribution of the main splints 601 on the short rod 6. The two sets of auxiliary splints 1701 are vertically distributed. When the short rod 6 drives the frame 8 to move intermittently, the auxiliary splints 1701 can cooperate with the positioning bar 801, combined with Figure 8 or Figure 12 As shown, viewed from the axial direction of the short rod 6 or the long rod 17, the auxiliary plates 1701 and the main plates 601 are arranged in a cross-symmetrical manner. In actual use, when the short rod 6 drives the long rod 17 to rotate, there is always a group of auxiliary plates 1701 or main plates 601 located on both sides of the positioning bar 801, thereby maintaining the stability of the frame 8.

[0042] Reference Figure 9 The side of the short rod 6 that fits the long rod 17 is fixed with a slide bar 602, and the side of the long rod 17 close to the short rod 6 is provided with a slide groove 1702 that slides with the slide bar 602. Through this structure, the short rod 6 can drive the long rod 17 to rotate synchronously, and the short rod 6 can slide along the axial direction of the long rod 17.

[0043] In actual use, the main rack 15 is engaged with the driving gear to drive the support frame 14 to move toward the spray booth 5, thereby preparing to push the frame 8 into the spray booth 5. In the initial state, a group of main splints 601 on the short rod 6 are located on both sides of the positioning bar 801. Figure 14 As shown, at this time, the slide 10 can drive the short rod 6 to move synchronously during the movement, thereby pushing the frame 8 into the spray booth 5 through the cooperation of the main splint 601 and the positioning bar 801. When the end of the short rod 6 is aligned with the end of the long rod 17, the slide 10 stops moving, at this time, driving the short rod 6 and the long rod 17 to rotate 180 degrees. Figure 12-13 As shown, during the rotation of the short rod 6 and the long rod 17, there is always a set of auxiliary splints 1701 or main splints 601 that can be located on the outside of the positioning bar 801 to maintain the stability of the frame 8. When the short rod 6 and the long rod 17 rotate 180°, the auxiliary splints 1701 on the long rod 17 can be on both sides of the positioning bar 801, thereby limiting the frame 8, and the main splint 601 on the short rod 6 rotates to a state staggered with the positioning bar 801. At this time, the slide plate 10 is driven to move in the direction away from the spray booth 5, so that the main splint 601 on the short rod 6 can be aligned with the last positioning bar 801 on the frame 8. For details, refer to Figure 13As shown, at this time, the short rod 6 and the long rod 17 are driven to rotate 180° again, so that the main splint 601 can be rotated to both sides of the positioning bar 801 again and the auxiliary splint 1701 is staggered with the positioning bar 801. Therefore, in the process of driving the slide plate 10 to approach the spray booth 5, the frame 8 can be further pushed into the spray booth 5. Repeating the above operation can gradually push the frame 8 into the spray booth 5, and during the entire pushing process, the frame 8 is always in a limited state, which is beneficial to improve the stability of the frame 8. Similarly, the above steps can be reversed to stably pull the frame 8 out of the spray booth 5. The specific process is not repeated here.

[0044] In summary, this device can push the frame 8 in the horizontal plane, so that it is not restricted by the space in the vertical direction, which is conducive to the frame 8 entering and exiting some narrow spaces. In addition, this device can always keep the frame 8 in a restricted state during the rotation of the short rod 6 and the long rod 17 through the cooperation of the main splint 601 and the auxiliary splint 1701, so that the main splint 601 or the auxiliary splint 1701 can be accurately located on both sides of the positioning bar 801 during the rotation, so that the distance between the two main splints 601 and the distance between the two auxiliary splints 1701 are slightly larger than the width of the positioning bar 801, thereby being able to push the frame 8 to move more stably.

[0045] Reference Figure 1-Figure 2 、 Figure 7 As shown, a rotating shaft 502 is fixedly provided at the center of the above-mentioned chuck 501, and the rotating shaft 502 is rotatably connected to the spray booth 5 and is driven to rotate by the motor at the spray booth 5. In actual use, the turntable 7 is adjusted so that the two insertion rods 701 are in a horizontal or vertical state, and the workpiece 4 is placed between the two support rollers 3. When the frame 8 enters the interior of the spray booth 5 and the insertion rod 701 passes through the insertion hole, the motor in the spray booth 5 can drive the chuck 501 to rotate, thereby driving the support roller 3 and the workpiece 4 to rotate.

[0046] Reference Figure 3 As shown, rollers 802 are installed on both sides of the bottom of the frame 8, and slide rails that cooperate with the rollers 802 are installed on the support frame 14, which facilitates the sliding of the frame 8 on the support frame 14. Similarly, a slide rail structure that cooperates with the rollers 802 also needs to be arranged at the spray booth 5.

[0047] Reference Figure 3 、 Figure 9-10As shown, brackets 19 are fixedly provided at both ends of the support frame 14, and the end of the long rod 17 passes through a preset through hole on the bracket 19. Specifically, an annular groove 1901 is provided on the inner wall of the through hole, and a clamping strip 1703 is fixedly provided on the outer peripheral wall of the long rod 17, and the clamping strip 1703 slides in the annular groove 1901. Of course, the cross-sections of the clamping strip 1703 and the annular groove 1901 can both be T-shaped structures.

[0048] A collar 18 is provided above the slide 10, through which both the short rod 6 and the long rod 17 pass. Figure 11 As shown, a slot 603 is provided on the outer peripheral wall of the short rod 6, and a plug-in block 1801 that cooperates with the slot 603 is fixedly provided on the inner wall of the ring 18. When the plug-in block 1801 is inserted into the slot 603, the ring 18 can drive the short rod 6 to rotate. In addition, the ring 18 can also drive the short rod 6 to move along the axial direction of the long rod 17. Vertical plates are fixedly provided on both sides of the top surface of the skateboard 10, and the short rod 6 and the long rod 17 both pass through the preset circular holes on the vertical plates. The short rod 6 can rotate relative to the vertical plates, and the long rod 17 can slide and rotate relative to the vertical plates.

[0049] A driving motor 9 is fixedly mounted on the slide 10 , and the driving motor 9 drives the collar 18 to rotate by a chain drive or a gear set drive.
