Description

Technical Field

[0001] This utility model relates to the field of grain storage technology, specifically to a special support for grain silo baskets. Background Technology

[0002] In the daily operations of grain silos, such as grain transportation, maintenance of internal equipment, and cleaning of the silo walls, it is often necessary to use baskets to transport personnel or materials to designated locations inside the silo.

[0003] Currently, most suspended support frames used for grain silos are fixed structures, with fixed lifting positions, allowing lifting operations only to be carried out in specific locations. When work needs to be carried out in different locations around the silo, fixed supports cannot meet the requirements, necessitating the reconstruction or relocation of the entire support structure. This process is cumbersome, consumes significant manpower and time costs, and poses certain safety hazards. Utility Model Content

[0004] In view of the problems existing in the special support for grain silo baskets, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a special support for grain silo baskets, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A special support frame for a grain silo basket includes a silo top plate and uprights. The uprights are positioned above the silo top plate on one side. A rear tie rod is provided between the upper end of the upright and the silo top plate. A first mounting seat and a second mounting seat are fixedly mounted at both ends of the upper surface of the silo top plate, respectively. The lower end of the upright is hinged to the first mounting seat. Both ends of the rear tie rod are hinged to the corresponding upright and the second mounting seat, respectively. A front horizontal bar is provided at the lower end of the upright, on the side away from the rear tie rod. One end of the front horizontal bar is connected to a third shaft. A connecting block is hinged to the pin, and the connecting block is fixedly connected to the upright. A first fixed pulley is rotatably provided at the upper end of the upright, and a second fixed pulley is rotatably provided at the end of the front horizontal rod away from the upright. A front pull rod is provided between the front horizontal rod and the upright. The upper end of the front pull rod is hinged to the upper end of the upright through a fourth axle pin. A first transmission mechanism is provided at the lower end of the front pull rod to drive the front horizontal rod to rotate around a third axle pin. A second transmission mechanism is provided on the wall of the upright to drive the front pull rod to rotate around a fourth axle pin.

[0008] Preferably, the first transmission mechanism includes a fixed sleeve and a first round pin. The fixed sleeve is connected to the wall of the front flat rod, and the first round pin is rotatably disposed on the front side of the fixed sleeve. A first strip opening is provided on the front side of the lower end of the front pull rod, and the front end of the first round pin passes through the first strip opening.

[0009] Preferably, the second transmission mechanism includes an internally threaded tube and a threaded rod. A through hole is provided on the upper side wall of the upright. The internally threaded tube is rotatably disposed on one side of the through hole. The threaded rod is threadedly sleeved inside the internally threaded tube. One end of the threaded rod passes through the through hole. A crossbar is fixedly disposed at the end of the threaded rod away from the internally threaded tube. A second round pin is rotatably disposed on the front side of the crossbar. A second slot is provided on the front side of the upper end of the front pull rod. The front end of the second round pin passes through the second slot.

[0010] Preferably, the front end of the first round pin is fixedly sleeved with a first anti-detachment ring.

Detailed Implementation

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] This utility model discloses a special support for grain silo hanging baskets.

[0024] Reference Figure 1-3 A special support frame for a grain silo basket includes a silo top plate 1 and uprights 4. The uprights 4 are located on one side above the silo top plate 1. A rear tie rod 7 is provided between the upper end of the uprights 4 and the silo top plate 1. A first mounting seat 2 and a second mounting seat 3 are fixedly provided at both ends of the upper surface of the silo top plate 1, respectively. The lower end of the uprights 4 is hinged to the first mounting seat 2. The two ends of the rear tie rod 7 are respectively hinged to the corresponding uprights 4 and the second mounting seat 3. A front horizontal rod 6 is provided at the lower end of the uprights 4, on the side away from the rear tie rod 7. One end of the front horizontal rod 6 is connected by a third pivot pin. A connecting block 5 is hinged and fixedly connected to the upright 4. A first fixed pulley 9 is rotatably installed at the upper end of the upright 4. A second fixed pulley 10 is rotatably installed at the end of the front horizontal bar 6 away from the upright 4. A front pull rod 11 is installed between the front horizontal bar 6 and the upright 4. The upper end of the front pull rod 11 is hinged to the upper end of the upright 4 through a fourth axle pin. A first transmission mechanism is installed at the lower end of the front pull rod 11 to drive the front horizontal bar 6 to rotate around the third axle pin. A second transmission mechanism is installed on the wall of the upright 4 to drive the front pull rod 11 to rotate around the fourth axle pin.

[0025] Reference Figure 1-3 The first transmission mechanism includes a fixed sleeve 14 and a first round pin 15. The fixed sleeve 14 is fixedly sleeved on the wall of the front flat rod 6. The first round pin 15 is rotatably disposed on the front side of the fixed sleeve 14. A first strip-shaped opening is opened on the front side of the lower end of the front pull rod 11. The front end of the first round pin 15 passes through the first strip-shaped opening. A first anti-disengagement ring is fixedly sleeved on the front end of the first round pin 15 to prevent the first round pin 15 from slipping out of the first strip-shaped opening as much as possible.

[0026] Reference Figure 1-3The second transmission mechanism includes an internally threaded tube 16 and a threaded rod 17. A through hole is provided on the upper side wall of the upright rod 4. The internally threaded tube 16 is rotatably disposed on one side of the through hole. The threaded rod 17 is threadedly sleeved inside the internally threaded tube 16. One end of the threaded rod 17 passes through the through hole. A crossbar 12 is fixedly disposed at the end of the threaded rod 17 away from the internally threaded tube 16. A second round pin 13 is rotatably disposed on the front side of the crossbar 12. A second slot is provided on the front side of the upper end of the front pull rod 11. The front end of the second round pin 13 passes through the second slot. A second anti-disengagement ring is fixedly sleeved on the front end of the second round pin 13 to prevent the second round pin 13 from slipping out of the second slot as much as possible. A vertical plate 18 is fixedly disposed at the end of the threaded rod 17 away from the second round pin 13. Sliding holes are provided on both sides of the upright rod 4 and located on both sides of the through hole. A sliding rod 8 is slidably disposed inside the sliding hole. One end of the sliding rod 8 is fixedly connected to the vertical plate 18 so that the vertical plate 18 can slide stably.

[0027] In this invention, when adjusting the hoisting position of the suspended platform, the internally threaded tube 16 is first rotated according to actual needs. As the internally threaded tube 16 rotates, the threaded rod 17, due to its connection with the vertical plate 18 via the sliding rod 8, cannot rotate and can only move horizontally along the axial direction of the internally threaded tube 16, thereby driving the horizontal rod 12 and the second round pin 13 to move horizontally. During this movement, the second round pin 13 pushes the second slot at the upper end of the front pull rod 11, causing the front pull rod 11 to rotate around the fourth shaft pin. When the front pull rod 11 rotates, its lower first slot pushes the first round pin 15. Since the first round pin 15 is rotatably connected to the fixed sleeve 14, and the fixed sleeve 14 is fixed to the front horizontal rod 6, the first round pin 15 slides within the first slot, causing the front horizontal rod 6 to rotate around the third shaft pin. After the front horizontal bar 6 rotates, the position of the second fixed pulley 10 on it changes, while the position of the first fixed pulley 9 on the vertical bar 4 remains unchanged. The combination of these two changes alters the direction of the hoisting rope and the hoisting position of the basket, thus facilitating hoisting operations at different locations on the ground. Throughout the adjustment process, the first and second anti-slip rings prevent the first round pin 15 and the second round pin 13 from slipping out of the slot, ensuring the stability and reliability of the adjustment process. Meanwhile, the cooperation between the sliding rod 8 and the vertical plate 18 ensures the smooth movement of the threaded rod 17, making the entire adjustment operation more precise and safer.

[0028] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
