Description

Technical Field

[0001] This invention relates to the field of conveying equipment technology, specifically a remotely controllable multi-degree-of-freedom conveyor. Background Technology

[0002] Multi-degree-of-freedom conveyors are commonly used supporting equipment in the field of industrial material conveying. Their multi-degree-of-freedom characteristics are mainly reflected in three core adjustment functions: overall rotation, machine body lifting, and conveyor structure extension and contraction. They are widely used in warehousing and logistics, production line docking, workshop material transfer and other scenarios. With their multi-dimensional adjustment capabilities, these devices can adapt to different work sites, conveying distances, docking heights and conveying angles. They can flexibly complete the continuous conveying of bulk materials and full-package goods, which is in line with the development trend of flexible and intelligent conveying in modern industry, and the application scenarios continue to expand.

[0003] Most existing multi-degree-of-freedom conveying equipment lacks the ability to remotely and precisely control the conveying stroke. The overall transmission linkage is poor, and problems such as uneven force and insufficient stability are prone to occur during adjustment. Conventional transmission structures experience relatively large wear and tear and have limited service life. They are difficult to adapt to various different conveying distance conditions, and the overall operating condition adaptability of the equipment is narrow. Furthermore, the conveying length adjustment generally relies on manual operation, and the level of intelligent control is insufficient. Adjustment operations are time-consuming and labor-intensive, making it difficult to meet the actual usage requirements of modern industrial automation and remote operation. Summary of the Invention

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1.

Conveyor 2 7 and conveyor 1 3 have the same structure, both being belt conveyors, consisting of a conveyor belt, drive roller, idler rollers, and frame. The drive roller drives the conveyor belt to rotate in a cycle, and the idler rollers support the conveyor belt and the material. Bulk materials or whole goods are transported by friction. Conveyor 2 7 is equipped with telescopic components 8 to adjust the effective conveying length of conveyor 1 3 and conveyor 2 7. The base plate 1 is equipped with rotating components 9 to control the rotation of conveyor 1 3 and conveyor 2 7. The bottom end of the base plate 1 is fixedly connected with universal wheels 10 with a self-locking structure. There are six sets of universal wheels 10, four of which are symmetrically distributed at the bottom end of the base plate 1, and the other two sets are symmetrically distributed at the bottom end of the two sets of height adjustment components 2 6 at the bottom end of the frame of conveyor 2 7 away from the base plate 1.

[0019] Reference Figures 3 to 4 The telescopic component 8 includes a mounting plate 81 fixedly connected to the inner side of the height adjustment component 26 at the bottom end of the frame of the second conveyor 7. The mounting plate 81 is distributed along the length of the second conveyor 7 and is fixedly connected to the two sets of height adjustment components 26. A rack 82 is fixedly connected to the top of the mounting plate 81. A fixing plate 83 is fixedly connected to the side end of the height adjustment component 2 at the bottom end of the frame of the first conveyor 3. A motor 84 is fixedly connected to the side of the fixing plate 83 away from the second conveyor 7. The output end of the motor 84 passes through the fixing plate 83 and is fixedly connected to a connecting rod 85. A gear 86 is fixedly connected to the outer surface of the connecting rod 85. The gear 86 meshes with the rack 82. Two sets of telescopic components 8 are provided and symmetrically distributed on both sides of the second conveyor 7.

[0020] The above scheme is adopted: the telescopic component 8 is composed of mounting plate 81, rack 82, fixing plate 83, motor 84, connecting rod 85, and gear 86 to form an overall transmission structure. It adopts a meshing transmission mode, which can smoothly drive the second conveyor 7 to slide linearly along the slide rail 4, accurately adjust the effective conveying length of the two sets of conveyors, and the transmission structure is compact and durable, runs smoothly without deviation, has high adjustment accuracy and fast response speed.

[0021] Reference Figures 5 to 6 Height adjustment component 12 includes an inner rod 21 fixedly connected to the bottom end of the conveyor 3 frame, and an outer rod 22 sleeved on the outside of the inner rod 21. Both the inner rod 21 and the outer rod 22 have C-shaped cross sections, and the C-shaped opening faces away from the conveyor 3. A hydraulic rod 23 is fixedly connected to the top of the base plate 1, and the hydraulic rod 23 is located inside the inner rod 21. The movable top end of the hydraulic rod 23 is fixedly connected to the bottom end of the conveyor 3 frame. Height adjustment component 26 has the same structure as height adjustment component 12. In two of the four sets of height adjustment components 26, the bottom end of the outer rod 22 is fixedly connected to the top end of the slider 5, and in the other two sets of height adjustment components 26, the bottom end of the outer rod 22 is fixedly connected to the top end of the caster wheel 10.

[0022] The above scheme is adopted: the height adjustment component 1 2 and the height adjustment component 2 6 are formed by the inner rod 21, the outer rod 22 and the hydraulic rod 23. The C-shaped cross section nested guide and the hydraulic rod 23 are used to drive the extension and retraction, so that the height of the conveyor 1 3 and the conveyor 2 7 can be adjusted independently. It can adapt to the docking height of different equipment and the material conveying drop. The nested structure has strong guiding performance, the lifting process is stable and does not shake, and the load is evenly distributed.

[0023] Reference Figures 7 to 8 The rotating component 9 includes a rotating disk 91 fixedly connected to the side of the base plate 1 away from the conveyor 7. The rotating disk 91 is U-shaped when viewed from above. A fixed frame 92 is provided on the rotating disk 91. The fixed frame 92 is U-shaped when viewed from the side. The rotating disk 91 is located inside the fixed frame 92. A motor 93 is fixedly connected to the top of the fixed frame 92. The output end of the motor 93 passes through the fixed frame 92 and is fixedly connected to the rotating disk 91. An adjustment groove 94 is provided at the bottom of the fixed frame 92. The adjustment groove 94 is a threaded groove. An abutment post 95 is threadedly connected inside the adjustment groove 94. When the top of the abutment post 95 abuts against the top of the inside of the adjustment groove 94, the bottom of the abutment post 95 is higher than the bottom of the universal wheel 10.

[0024] The above solution is adopted: the rotating part 9 is composed of a rotating disk 91, a fixed frame 92, a second motor 93, an adjusting groove 94, and abutting column 95. The rotating disk 91 is driven by the second motor 93 to realize the multi-angle rotation adjustment of the whole machine. With the help of the threaded abutting column 95, it can be quickly landed for support and fixation, realize multi-degree-of-freedom steering and positioning, meet the multi-angle material conveying and docking needs of complex sites, and has stable positioning and convenient operation.

[0025] The working principle of this invention is as follows: In actual use, the six sets of casters 10 arranged at the bottom of the base plate 1 can first be used to easily push the whole machine to the designated working position for material conveying. After being pushed into place, the self-locking structure of the casters 10 is locked to complete the initial positioning of the whole machine and prevent the equipment from sliding or shifting during operation. The operator can issue control commands through the remote control system to control the start and stop of each electrical component. First, according to the height difference requirements of the on-site loading and unloading equipment, the hydraulic rods 23 inside the height adjustment component 1 2 and the height adjustment component 2 6 are activated. The hydraulic rods 23 extend and retract to push the inner rod 21 to slide vertically along the inside of the outer rod 22. The C-shaped inner rod 21 and the outer rod 22 are nested together. Limiting mechanisms ensure vertical guidance and prevent lateral deviation during lifting. Four sets of height adjustment components (2) synchronously adjust the overall height of conveyor (3), and four sets of height adjustment components (6) synchronously adjust the overall height of conveyor (7), ensuring precise alignment of the feed and discharge ends of both conveyors with the upstream and downstream equipment. After height adjustment, based on the required material conveying distance and path length, the motor (84) in the telescopic component (8) is remotely activated. Motor (84) drives the connecting rod (85) and gear (86) to rotate synchronously. Gear (86) meshes with the rack (82) at the top of the mounting plate (81), and the two symmetrically arranged telescopic components (8) synchronously drive the slider (5) at the bottom of conveyor (7) along the top of the base plate (1). The slide rail 4 slides linearly, thereby changing the extension length of conveyor 2 7 relative to conveyor 1 3, accurately adjusting the overall effective conveying stroke, and adapting to different conveying distance conditions. When the working space is limited and the conveying angle needs to be readjusted, first rotate and twist the abutment column 95, so that the abutment column 95 slowly moves down along the threaded track of the adjusting groove 94 until it touches the ground. Relying on the bottom end of the abutment column 95 contacting the ground to form a stable friction force, the rotation center fulcrum of the whole machine is established. Then, release the self-locking limit state of all universal wheels 10, allowing the universal wheels 10 to roll freely. After that, remotely start the motor 2 93 of the rotating component 9. The output end of the motor 2 93 drives the rotating disk 91 to rotate smoothly inside the fixed frame 92. This drives the base plate 1 and the entire conveying structure above it to make a fixed-point angle deflection with the vertical axis of the abutment column 95 as the center. At the same time, with the help of the follow-up rolling of the universal wheel 10, the turning process of the whole machine is smooth and without jamming, and the multi-directional angle adjustment is easily completed. After the angle is adjusted to the appropriate conveying position, the universal wheel 10 is locked again to fix the position. The abutment column 95 is twisted in the opposite direction to make it rise and lift off the ground, restoring the equipment to the normal support state. After all the height, length and angle adjustments are completed, the drive mechanism of conveyor 1 3 and conveyor 2 7 is remotely started. The drive roller drives the conveyor belt to rotate in a cycle, and the idler rollers continuously support the conveyor belt and materials. The friction force is used to complete the continuous conveying operation of bulk materials and whole goods.The telescopic component 8, driven by motor 84, engages gear 86 and rack 82, allowing for remote and precise control of the sliding stroke of conveyor 7 on slide rail 4. This flexibly alters the effective conveying length of conveyors 3 and 7. The telescopic components 8, symmetrically arranged on both sides, provide synchronous transmission, ensuring even force distribution and smooth operation. The meshing transmission structure boasts high efficiency and wear resistance, adapting to varying conveying distance requirements and significantly expanding the equipment's operational range. Furthermore, the adjustment process eliminates the need for manual pushing and pulling, allowing for remote control and saving time and effort. Height adjustment components 2 and 6, employing an inner rod 21 and outer rod 22 nested in a C-shape with a hydraulic rod 23, drive lifting and lowering, enabling independent adjustment of the installation height of conveyors 3 and 7 for precise matching. The nested cross-section provides excellent guidance and limiting for downstream equipment docking height differences, preventing deviation and tilting during lifting. The hydraulically driven lifting system boasts strong load-bearing capacity and smooth operation. Multiple sets of adjusting components operate synchronously to ensure the frame's levelness, meeting the docking and conveying needs of different sites and equipment heights. The rotating component 9 first lowers the abutment column 95 to contact the ground, forming a rotation fulcrum. Then, the self-locking of the universal wheel 10 is released, and the motor 93 drives the rotating disk 91 to deflect the entire machine around the axis of the abutment column 95, achieving fixed-point multi-angle steering adjustment. A stable rotation center is established based on the abutment column 95, and the universal wheel 10 follows the steering, ensuring a smooth and non-tipping steering process. This adaptable to working environments with limited site angles, the adjustment process is standardized and orderly, with precise positioning and convenient operation.
