Description

Technical Field

[0001] This utility model relates to the field of screw conveyor technology, specifically a support device for screw conveyors. Background Technology

[0002] In reality, there are several types of conveyors, including integrated loading and unloading conveyors, belt conveyors, screw conveyors, bucket elevators, roller conveyors, plate chain conveyors, mesh belt conveyors, and chain conveyors. Regardless of the type of conveyor, a support structure is required for support. During the conveying process, the conveyor will transport various different items with different volumes and weights.

[0003] As disclosed in patent announcement number CN219525283U, a support device for a screw conveyor includes a support plate. A ring is fixedly connected to the top of the support plate, and a limiting groove is formed inside the ring. A connecting ring is sleeved inside the ring. A top plate is connected to the top of the support plate, and a connecting mechanism for connecting the top plate is provided on the top of the support plate. Four sliders slide on the bottom of the support plate, arranged symmetrically in pairs. The beneficial effect of this utility model is that by setting the support rod, the device can be raised and lowered, avoiding the inability to adjust the fixed height at both ends of the conveyor during installation, which would increase the load on the conveyor during operation.

[0004] Although the aforementioned patent allows for lifting and lowering, the lifting and lowering method is rather cumbersome, and the time required to lift and lower the device increases as the number of support components increases. Utility Model Content

A lifting frame 3 and a lifting frame 4 are respectively arranged inside the guide rails 2. An angle adjustment mechanism is provided between the lifting frame 3 and the lifting frame 4. The angle adjustment mechanism includes a mounting plate 8, which is movably arranged between the top ends of the lifting frame 3 and the lifting frame 4. The right end of the mounting plate 8 is movably connected to the middle of the top end of the lifting frame 4 via a rotating shaft. Shafts are provided at the lower middle of the right side of the lifting frame 3 and the lower middle of the left side of the mounting plate 8. 9. An electric actuator 10 is movably arranged between the shaft frames 9. A support frame 5 is arranged between the middle of both sides of the guide rails 2. A mounting frame 6 is arranged between the middle of the support frames 5. A drive mechanism is arranged in the middle of the mounting frame 6. The drive mechanism includes a motor 11.

The output shaft of the motor 11 is fixedly connected to the lead screw 12. A movable sleeve 13 is movably installed outside the lead screw 12. Movable frames 14 are symmetrically arranged on both sides of the movable sleeve 13.

[0027] In this embodiment, the extension and retraction of the electric actuator 10 drives the mounting plate 8 to rotate around the pivot, thereby realizing the flexible adjustment of the angle of the mounting plate 8. This can adapt to different working requirements and improve the applicability of the device. The use of the electric actuator 10 makes the angle adjustment process simple and intuitive, eliminating the need for complicated manual operation, reducing the difficulty of operation, and ensuring the accuracy and stability of the adjustment, thus improving work efficiency.

[0028] like Figure 1 and Figure 2 As shown, a base frame 7 is provided at the top center of the base 1. Lifting mechanisms are provided on both sides of the base frame 7. The lifting mechanism includes a guide groove 15. Guide groove 15 is provided on both sides of the center of the base frame 7. Guide groove 2 16 is provided on both sides of the base frame 7 and communicates with guide groove 15. Bearing 17 and bearing 2 18 are movably arranged between guide groove 15 and guide groove 2 16. The lifting mechanism cooperates with the drive mechanism. Support rod 19 is movably arranged between bearing 17 and movable frame 14. Support rod 20 is movably arranged between bearing 2 18 and lifting frame 3 and lifting frame 4.

[0029] In this embodiment, the motor 11 drives the lead screw 12 and the movable sleeve 13 in coordination, combined with the linkage structure of the support rod and bearing, to realize the automated operation of the lifting process. No manual adjustment is required, which significantly improves the lifting efficiency. Especially in scenarios where frequent height adjustments are required, the lifting operation can be completed quickly. The precise coordination of the guide rail 2, the support rod and the bearing ensures the stability and accuracy of the lifting process, avoiding the shaking or deviation problems common in traditional lifting devices, and improving the stability and reliability of the device.

[0030] Working principle: The guide rails 2, symmetrically arranged on both sides of the top of the base 1, house lifting frames 3 and 4 respectively. These are connected by an angle adjustment mechanism, which includes a mounting plate 8. The right end of the mounting plate 8 is movably connected to the center of the top of the lifting frame 4 via a rotating shaft. Shafts 9 are located at the lower center of the right side of the lifting frame 3 and the lower center of the left side of the mounting plate 8. An electric push rod 10 is movably mounted between the shafts 9. The extension and retraction of the electric push rod 10 drives the mounting plate 8 to rotate around the rotating shaft via the shafts 9, thus achieving the angle adjustment function of the mounting plate 8. A base frame 7 is located at the top center of the base 1. Lifting mechanisms are located on both sides of the base frame 7. These lifting mechanisms include guide groove 15 and guide groove 2 16. Bearings 17 and 28 are movably mounted between guide groove 15 and guide groove 2 16. Bearing 17 is connected to the movable frame 14 via a support rod 19.

A mounting frame 6 is installed in the middle of the support frame 5. A drive mechanism is provided in the middle of the mounting frame 6. The drive mechanism includes a motor 11. The output shaft of the motor 11 is fixedly connected to the lead screw 12. A movable sleeve 13 is movably installed on the outside of the lead screw 12. Movable frames 14 are symmetrically provided on both sides of the movable sleeve 13. The motor 11 drives the lead screw 12 to rotate, which drives the movable sleeve 13 to move. The movable sleeve 13 pushes the bearing 17 to move in the guide groove 15 and guide groove 26 via the support rod 19. The movement of the bearing 17 drives the lifting frame 3 and lifting frame 4 to move up and down in the guide rail 2 via the support rod 20. The rotational motion of the motor 11 is converted into the linear motion of the lifting frame by the lever principle, thereby realizing the lifting function of the entire device.
