Description

Technical Field

[0001] The utility model belongs to the technical field of transportation devices, and in particular relates to a lifting conveyor device. Background Art

[0002] Material baskets are typically used to hold items. Once placed inside, these items typically require loading and unloading. Transferring the material basket is accomplished by placing the basket onto a corresponding rail transport device. Patent publication number CN116216211A discloses a labor-efficient, short-distance round-trip rail transport device. The device comprises a rail trolley and a track positioned between two fixed workstations, with upturned ends and baffles. The trolley is positioned on the track and equipped with a holding brake, which is provided with two resiliently retractable brake levers. Existing rail transport devices can only transport items back and forth in a single direction along the track, resulting in a long axial travel distance and the inability to transport items in multiple axial directions. When loading and unloading materials at different axial positions are required, existing monorail transport devices are inadequate for conveniently transporting the material basket, resulting in poor versatility. Therefore, a jacking conveyor device is needed to overcome these difficulties. Summary of the Invention

[0008] Two side-by-side lower roller assemblies facilitate the back-and-forth circulation of the material frame. One lower roller assembly is used for loading, and the other for unloading. The two lower roller assemblies are transported between them via a horizontal transfer assembly. The material frame first moves along the loading lower roller assembly to the bottom frame, where it is then located on the upper frame above the bottom frame. The jacking assembly then lifts the upper frame, allowing the material frame to separate from the loading lower roller assembly. The horizontal transfer assembly then carries the material frame to the unloading lower roller assembly, where it is then lowered by the jacking assembly, automatically dropping onto the unloading lower roller assembly. After unloading is complete, the material frame is reversely transported via the unloading lower roller assembly and the horizontal transfer assembly, returning it to the loading lower roller assembly, where reloading can begin. The specific working process of the lower roller assembly is as follows: when the first reduction motor is working, the second rotating assembly is driven to rotate through the first chain; when the second rotating assembly rotates, the first rotating assembly is driven to rotate through the second chain; the second rotating assembly is connected to the third rotating assembly through the third chain, the fourth chain and the fifth chain, so that the third rotating assembly will rotate synchronously; the two adjacent third rotating assemblies are transmitted through the seventh chain, so that after the first reduction motor is working, the first rotating assembly, the second rotating assembly and the third rotating assembly will rotate synchronously; here the fourth chain and the seventh chain are set lower than the third rotating assembly, which avoids interference between the fourth chain and the seventh chain relative to the upper frame, so that the upper frame can move up and down smoothly.

[0011] Preferably, each of the transverse rollers is arranged side by side and adjacent to each other, and a ninth chain for transmission is provided between the transverse rollers.

[0013] Preferably, each of the horizontal transfer components is arranged side by side on the upper frame, and a longitudinal transmission shaft is provided between two adjacent horizontal transfer components; the horizontal transfer component includes a mounting frame, a chain guide wheel, a transmission chain and a conveyor chain guide rail, and the mounting frame is fixedly mounted on the upper frame; both ends of the mounting frame are provided with chain guide wheels rotatably connected thereto, and the upper end face of the mounting frame is provided with a conveyor chain guide rail fixedly connected thereto, and the transmission chain is sleeved and mounted on the chain guide wheel; a driving sprocket is provided on the longitudinal transmission shaft, and a tensioning wheel assembly is also provided on the mounting frame, and the transmission chain passes around the driving sprocket and the tensioning wheel assembly in turn; a third reduction motor is provided on the upper frame fixedly connected thereto, and a tenth chain is provided between the third reduction motor and one of the longitudinal transmission shafts; when the third reduction motor drives the longitudinal transmission shaft to rotate, the transmission chains on each of the mounting frames rotate synchronously.

[0014] Preferably, the tensioning wheel assembly includes a pair of screws, and also includes a fixed tensioning wheel and a sliding tensioning wheel; the screws are fixedly installed on the mounting frame, and a tensioning wheel shaft is provided between the two screws; the tensioning wheel shaft is slidingly connected to the screw, and nuts are provided at both ends of the tensioning wheel shaft that are threadedly connected to the screw; a sliding tensioning wheel is provided on the tensioning wheel shaft and is rotatably connected to it, and a fixed tensioning wheel is provided on the mounting frame; the fixed tensioning wheel and the sliding tensioning wheel are arranged at the same horizontal height; the driving sprocket is arranged between the fixed tensioning wheel and the sliding tensioning wheel, and the driving sprocket is arranged lower than the tensioning wheel shaft; the transmission chain passes through the fixed tensioning wheel, the sliding tensioning wheel and the driving sprocket at the same time.

[0015] When the third reduction motor is working, it drives the longitudinal transmission shaft to rotate through the tenth chain. When the longitudinal transmission shaft rotates, it drives the driving sprocket to rotate. When the driving sprocket rotates, it drives the tensioning wheel assembly and the transmission chain to rotate. In this way, the transmission chain can continuously rotate relative to the mounting frame, thereby facilitating the transport of the material frame. By rotating the third reduction motor in the forward and reverse directions, the moving direction of the material frame can be adjusted. When the tension of the transmission chain needs to be adjusted, the nut is first loosened, and then the spacing between the fixed tensioning wheel and the sliding tensioning wheel is adjusted through the tensioning wheel shaft. Then, the tensioning wheel shaft is locked through the nut, which makes it convenient to adjust the tension.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention facilitates the loading and unloading processes of the material frame by arranging the lower roller assemblies side by side, thereby facilitating the circulating transfer of products in the material frame; 2. The upper frame is controlled to rise and fall relative to the lower roller assembly on the bottom frame by the jacking assembly, so that the material frame can be temporarily separated from the lower roller assembly, and the material frame can be transferred perpendicular to the direction of the lower roller assembly by the horizontal transfer assembly, which has better versatility; 3. The material frame can be transferred back and forth between the two lower roller assemblies by the horizontal transfer assembly, and the transfer efficiency is high and the transfer can be carried out continuously.

[0031] The specific operation process of the embodiment is as follows: the material frame is placed on the lower roller assembly 2, so that the material frame can be transferred; the two lower roller assemblies 2 arranged side by side facilitate the back-and-forth circulation transfer of the material frame. One of the lower roller assemblies 2 is used for feeding, and the other lower roller assembly 2 is used for discharging; the two lower roller assemblies 2 are transported through the horizontal transfer assembly 5; the material frame first moves along the feeding lower roller assembly 2 to the bottom frame 1, and then the material frame is on the upper frame 3 above the bottom frame 1, then the jacking assembly 4 lifts the upper frame 3, so that the material frame is separated from the feeding lower roller assembly 2; then the horizontal transfer assembly 5 moves with the material frame to the discharging lower roller assembly 2, and then the jacking assembly 4 controls the material frame to descend, so that the material frame automatically falls to the discharging lower roller assembly 2; when the discharging is completed, the material frame is transferred in the reverse direction through the discharging lower roller assembly 2 and the horizontal transfer assembly 5, so that the material frame returns to the feeding lower roller assembly 2, and then the feeding is restarted.

[0032] When the material frame is on the upper frame 3, the jacking assembly 4 starts to work; when the second speed reducer 42 works, one of the transverse rollers 41 is driven to rotate through the eighth chain 43, and the transverse rollers 41 are connected in transmission through the ninth chain 46, so that all the transverse rollers 41 rotate synchronously; the end of the transverse roller 41 is provided with a cam block 44, the cam block 44 is in strip shape, and the end of the cam block 44 is provided with a rolling bearing 45; then the cam block 44 can drive the rolling bearing 45 to rise and fall when it rotates, and the support 8 abuts against the rolling bearing 45, so that the rolling bearing 45 can push the upper frame 3 to rise and fall when it rises and falls; by default, the horizontal transfer assembly 5 of the upper frame 3 is arranged flush with the upper end surface of the lower roller assembly 2, so that the material frame on the lower roller assembly 2 can be automatically transferred to the horizontal transfer assembly 5; when the jacking assembly 4 controls the upper frame 3 to rise, the horizontal transfer assembly 5 carries the material frame to separate from the lower roller assembly 2 synchronously.

[0033] The working process of the horizontal transfer component 5 is as follows: the third reduction motor 57 drives the longitudinal transmission shaft 55 to rotate through the tenth chain 58, and when the longitudinal transmission shaft 55 rotates, it drives the driving sprocket 56 to rotate, and when the driving sprocket 56 rotates, it can drive the tensioning wheel assembly 9 and the transmission chain 53 to rotate; in this way, the transmission chain 53 can continue to rotate relative to the mounting frame 51, thereby facilitating the transfer of the material frame; by the forward and reverse rotation of the third reduction motor 57, the moving direction of the material frame can be adjusted; when the tension of the transmission chain 53 needs to be adjusted, first loosen the nut 95, and then adjust the distance between the fixed tensioning wheel 92 and the sliding tensioning wheel 93 through the tensioning wheel shaft 94, and then lock the tensioning wheel shaft 94 through the nut 95, so that the tension can be easily adjusted.
