[0020] The present invention provides an adjustable high-load-bearing chain conveyor and a method of using the same. Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The adjustable high-load-bearing chain conveyor and its use method are provided with a lifting unit. The operation of the driving assembly drives the two groups of moving assemblies located in the internal limit of the limit assembly to move toward each other. The limit assembly moves toward each other to drive the first connecting rod and the second connecting rod to rotate in an arc toward each other. The first connecting rod and the second connecting rod drive the fixed column to move upward. The fixed column drives the mounting plate to move synchronously through the fixed seat. The mounting plate drives the secondary conveying frame to rotate in an arc, thereby realizing a docking platform that allows the conveying mechanism to adapt to different carriers.

[0022] 2. The adjustable high-load-bearing chain conveyor and its use method are provided with a moving assembly. The moving rod realizes the rolling of the pulley inside the limiting slide groove through the rotating column, so that when the moving rod moves toward or in the opposite direction, the friction of the moving rod is reduced, and the bottom ends of the first connecting rod and the second connecting rod are prevented from getting stuck due to excessive friction when the right end of the conveying mechanism is lifted. At the same time, the block is fixedly installed in the groove by bolts, and the pulley is fixedly installed at one end of the rotating column by bolts, so that the pulley is easy to replace.

[0023] 3. The adjustable high-load-bearing chain conveyor and its use method are provided with a positioning unit.

Detailed implementation manners

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to Figures 1 - 10 , the present invention provides a technical solution:

[0037] An adjustable high-load chain conveyor and its usage method, including a conveying mechanism 1. A lifting mechanism 2 is arranged on the right side of the conveying mechanism 1 to lift one end of the conveying mechanism 1 to achieve an adaptation to different vehicle connection platforms. The lifting mechanism 2 includes:

[0038] A lifting unit 21, arranged on the right side of the conveying mechanism 1, includes a set of mounting plates 211. A fixed seat 212 is fixedly installed at the bottom of the mounting plate 211. A fixed column 213 is fixedly installed inside the fixed seat 212. A set of first connecting rods 214 and a set of second connecting rods 215 are fixedly installed on the surface of the fixed column 213. Driving components 5 are arranged at the bottom ends of both the first connecting rod 214 and the second connecting rod 215. A driving component 5 is arranged inside the moving component 4 to drive the moving component 4. A limiting component 6 is arranged outside the moving component 4 to limit the movement of the moving component 4;

[0039] A positioning unit 22, arranged on the front and rear sides of the lifting unit 21, and used to position the positions of the first connecting rod 214 and the second connecting rod 215.

[0040] Through the linkage design of the lifting unit 21, the driving component 5, and the moving component 4, the lifting adjustment function of the right end of the conveying mechanism 1 is realized. The opposite arc rotation of the first connecting rod 214 and the second connecting rod 215 drives the vertical movement of the fixed column 213, so that the mounting plate 211 and the secondary conveying frame 12 are synchronously adjusted in angle and height. This structure breaks through the rigid limitation of the traditional conveyor, can dynamically adapt to the height difference of different vehicle connection platforms, significantly improves the multi-dimensional space adaptation ability of the equipment, and solves the problem of low efficiency caused by height mismatch in scenarios such as production line docking, loading and unloading of vehicles, etc.

[0041] In this embodiment, the moving component 4 includes a moving rod 41. Card slots 42 are opened at both ends of the moving rod 41. A clamping block 43 is inserted into the card slot 42. The clamping block 43 is fixedly installed inside the card slot 42 through bolts. A rotating column 44 is rotatably installed on one side of the clamping block 43. A pulley 45 is fixedly installed at one end of the rotating column 44 through bolts. The rotating column 44 is respectively rotatably installed inside the bottom ends of the first connecting rod 214 and the second connecting rod 215.

[0042] The moving component 4 adopts a rolling fit design of a moving rod 41 and a pulley 45. The pulley 45 rolls in the limit chute 64, greatly reducing the friction of the moving rod 41 and avoiding the defect of easy jamming of the traditional sliding structure. At the same time, the clamping block 43 and the clamping groove 42 are fixed by bolts, which is convenient for quickly disassembling and replacing the pulley 45, reducing the maintenance cost. This design not only improves the fluency of the adjustment process but also enhances the modular maintenance ability of the device.

[0043] In this embodiment, the driving component 5 includes a first base plate 51 and a group of second base plates 52. A rotating shaft 53 is rotatably installed at the top of the first base plate 51. A rotating rod 54 is fixedly installed at the top end of the rotating shaft 53. Connecting rods 55 are rotatably installed at both ends of the rotating rod 54. One ends of the connecting rods 55 are respectively movably connected to the clamping grooves 42. A worm gear 56 is fixedly installed on the surface of the rotating shaft 53. A driving motor 57 is fixedly installed at the top of the second base plate 52. A worm 58 is fixedly installed at one end of the driving motor 57. The worm 58 is meshed with the worm gear 56. A bearing seat 59 is fixedly installed on one side of the first base plate 51. A support bearing 510 is fixedly installed at the top of the bearing seat 59. One end of the worm 58 is located inside the support bearing 510 and rotates.

[0044] The driving component 5 adopts the meshing transmission of the worm gear 56 and the worm 58. Combined with the control of the driving motor 57, it realizes high-precision and low-noise power output. The worm and worm gear transmission has a self-locking characteristic, which can automatically maintain the current height position when power is off or the machine stops, preventing accidental sliding. In addition, the rotating shaft 53 drives the moving component 4 through the connecting rod 55, ensuring the synchronism and stability of the transmission, and further improving the safety and adjustment reliability of the device.

[0045] In this embodiment, the limiting component 6 includes a chassis 61. The first base plate 51 and the second base plate 52 are both fixedly installed inside the chassis 61. A limiting frame 62 is fixedly installed at the top of the chassis 61 by bolts. Limiting chutes 64 are opened on both the front and rear sides of the limiting frame 62. The pulley 45 is located inside the limiting chute 64 and rolls. A limiting rod 63 is inserted and installed inside the limiting frame 62. The limiting rod 63 is fixed to the limiting frame 62 by bolts. The moving rod 41 slides on the surface of the limiting rod 63 to realize the movement limit of the moving rod 41.

[0046] The limiting component 6 restricts the movement track of the moving rod 41 through the multiple limiting design of the chassis 61, the limiting frame 62 and the limiting rod 63. The pulley 45 rolls in the limiting chute 64, and the limiting rod 63 rigidly guides the sliding path of the moving rod 41, providing double guarantees for the linearity and stability of the moving process, effectively preventing deviation or vibration, and ensuring the accurate positioning of the conveying mechanism 1 during the lifting adjustment.

[0047] In this embodiment, the positioning unit 22 includes a connecting column 221 rotatably installed outside the first connecting rod 214, and a moving column 222 is fixedly installed outside the second connecting rod 215. One end of the connecting column 221 is fixedly installed with a linkage rod 223, and a waist slot 224 is formed inside the linkage rod 223. The moving column 222 slides inside the waist slot 224. One end of the moving column 222 is rotatably installed with a threaded knob rod 225, and a movable plate 227 is threadedly installed on the surface of the threaded knob rod 225. One side of the movable plate 227 is fixedly installed with a limiting block 226, and the limiting block 226 slides inside the waist slot 224. An insertion block 228 is fixedly installed on the inner side of the limiting block 226. A slot plate 229 is fixedly installed on the top of the linkage rod 223, and the insertion block 228 is inserted into the inside of the slot plate 229.

[0048] The positioning unit 22 drives the insertion block 228 to be inserted and locked with the slot plate 229 through the threaded knob rod 225, realizing the rigid fixation of the first connecting rod 214 and the second connecting rod 215. The sliding fit between the waist slot 224 and the limiting block 226 allows for adaptive displacement during the adjustment process, and the displacement risk of the connecting rod can be completely eliminated after the final locking. This design solves the problem that the locking of the worm and worm gear transmission is prone to loosening, especially suitable for high-load scenarios, and significantly improves the impact resistance and long-term stability of the equipment in the fixed state.

[0049] In this embodiment, the conveying mechanism 1 includes a main conveying frame 11, and the bottom frame 61 is fixedly installed on the right side of the main conveying frame 11. A secondary driving sprocket group 14 is arranged inside the main conveying frame 11, and a driving sprocket group 13 is rotatably connected to the right side of the main conveying frame 11. The driving sprocket group 13 is arranged on the right side of the secondary conveying frame 12. A chain 15 is connected between the driving sprocket group 13 and the secondary driving sprocket group 14. A plurality of conveying plates 16 are fixedly installed on the inner side of the chain 15, and a plurality of baffle plates 17 are arranged on the outer side of the conveying plates 16. Mounting plates 211 are fixedly installed on the front and rear sides of the conveying mechanism 1, and tensioning assemblies 3 are arranged on the front and rear sides of the secondary conveying frame 12.

[0050] The conveying mechanism 1 drives the chain 15 through the sprocket groups 13 and 14 of the main conveying frame 11 and the secondary conveying frame 12. Combining with the spring 310 adaptive adjustment function of the tensioning assembly 3, it ensures that the chain 15 is always in a reasonable tension state. The modular design of the conveying plate 16 and the baffle plate 17 enhances the stability of material conveying and the anti-dropping ability. The sliding adjustment structure of the tensioning sprocket 36 further reduces the wear of the chain caused by load changes and extends the service life of the equipment.

[0051] In this embodiment, the conveying mechanism 1 includes a main conveying frame 11, and the base frame 61 is fixedly installed on the right side of the main conveying frame 11, a secondary moving sprocket group 14 is arranged inside the main conveying frame 11, and the right side of the main conveying frame 11 is rotatably connected with a driving sprocket group 13, and a driving sprocket group 13 is arranged on the right side of the secondary conveying frame 12, and a chain 15 is connected between the driving sprocket group 13 and the secondary moving sprocket group 14, and a plurality of conveying plates 16 are fixedly installed on the inner side of the chain 15, and a plurality of baffles 17 are arranged on the outer side of the conveying plate 16, and the mounting plate 211 is fixedly installed on the front and rear sides of the conveying mechanism 1, and a tensioning assembly 3 is arranged on the front and rear sides of the secondary conveying frame 12.
