Description

Technical Field

[0001] The invention belongs to the technical field of logistics loading and unloading, and in particular relates to an auxiliary device for logistics loading and unloading. Background Art

[0002] Logistics loading and unloading refers to activities carried out within the same geographical area (such as warehouses, stations, docks, factories, etc.) with the main purpose of changing the storage status and spatial location of goods. It includes loading and unloading goods on transportation vehicles, as well as stacking, unstacking, and moving goods in warehouses and other places. For example, moving goods from truck compartments to warehouse shelves, or taking goods out of warehouses and loading them onto transportation vehicles such as ships.

[0003] In the Chinese patent with publication number CN219990607U, a loading and unloading auxiliary device for automobile logistics conveyor line is mentioned. Its specification discloses that by setting a connecting block, a movable block one and a movable block two, the movable block two can be moved upward due to the operation of the electric telescopic rod. At this time, the mounting block one will rotate along the axis hinged with the mounting block two, and the movable block two will rotate along the axis hinged with the fixed block, and an upward thrust is applied to the right side of the bottom of the mounting plate through the movable block two, and the mounting plate drives the movable block one to rotate along the axis hinged with the connecting block. At this time, the inclination angle of the mounting plate and the automobile logistics conveyor line can be adjusted, and the height of the mounting plate and the right side of the automobile logistics conveyor line can be adjusted. This design can adjust the angle of the mounting plate and the automobile logistics conveyor line according to the height of the automobile container, and at the same time reduce the restrictions when the loading and unloading auxiliary device is used, thereby increasing the application range of the loading and unloading auxiliary device for automobile logistics conveyor line;

[0004] However, in the above application, although the height of the conveyor is adjusted to match the height of the vehicle body, this height adjustment is achieved by adjusting the entire frame. This adjustment method has obvious disadvantages, because during the adjustment process, the inclination angle of the entire frame will become too large. This excessive inclination angle will have a series of adverse effects on the transportation process of the goods, such as causing the goods to slide too fast and collide during transportation due to gravity and the inclination angle, which may cause damage to the goods and undermine the stability of the entire transportation process. Summary of the invention

[0005] The purpose of the present invention is to provide an auxiliary device for logistics loading and unloading, so as to solve the problem in the prior art that the existing conveying device is disadvantageous to the goods when adjusting the angle.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] An auxiliary device for logistics loading and unloading, comprising four rectangular frames, wherein rectangular columns are slidably connected to the interior of the four rectangular frames, and a first conveyor belt is commonly arranged between the four rectangular columns, and further comprising:

[0008] An auxiliary mechanism, which is used to assist in unloading the first conveyor belt, the auxiliary mechanism includes a base fixedly connected to one of the rectangular columns, the surface of the base is fixedly connected to a first motor, the output end of the first motor is fixedly connected to a rotating rod, the arc surface of the rotating rod is fixedly connected to a fixed block, the surface of the fixed block is fixedly connected to a second conveyor belt, the surfaces of the four rectangular frames are all installed with electric telescopic rods, and the output ends of the four electric telescopic rods are respectively fixedly connected to the four rectangular columns;

[0034] In this embodiment, the first conveyor belt 102 is an existing mechanism and will not be described in detail herein.

[0035] An auxiliary mechanism 2, which is used to assist in unloading the first conveyor belt 102, and the auxiliary mechanism 2 includes a base 201 fixedly connected to one of the rectangular columns 101, a first motor 202 is fixedly connected to the surface of the base 201, a rotating rod 203 is fixedly connected to the output end of the first motor 202, a fixed block 204 is fixedly connected to the circular arc surface of the rotating rod 203, a second conveyor belt 205 is fixedly connected to the surface of the fixed block 204, and electric telescopic rods 206 are installed on the surfaces of the four rectangular frames 1, and the output ends of the four electric telescopic rods 206 are fixedly connected to the four rectangular columns 101 respectively;

[0036] In this embodiment, the two electric telescopic rods 206 on one side of the first conveyor belt 102 are started to drive the two rectangular columns 101 to move upward.

[0037] In an optional embodiment: the arc surface of the rotating rod 203 is rotatably connected to the limiting plate 2031 , and the limiting plate 2031 is fixedly connected to the side wall of one of the rectangular columns 101 .

[0038] It should be noted that when the rotating rod 203 rotates, it will rotate along the surface of the limiting plate 2031 , and the limiting plate 2031 plays a role of limiting support for the rotating rod 203 .

[0039] In an optional embodiment: four rectangular frames 1 are grouped in pairs, and the side of the same group of rectangular frames 1 that are close to each other is fixedly connected with a long rod 207, the arc surfaces of the two long rods 207 are fixedly connected with a sliding frame 208, the insides of the two sliding frames 208 are slidably connected with a sliding column 209, the side of the two sliding columns 209 that are close to each other is rotatably connected with a round roller 210, and the round roller 210 is located inside the first conveyor belt 102.

[0040] It should be noted that the sliding column 209 is moved to move the round roller 210 to tighten the belt of the first conveyor belt 102, so as to avoid the situation where the first conveyor belt 102 is tilted too much.

[0043] The cleaning mechanism 3 is used to clean the first conveyor belt 102 when it is not in use, and can also tension and support the belt of the first conveyor belt 102 .

[0044] In a further embodiment, referring to Figure 2 , Figure 5 , Figure 7 and Figure 8 As shown, the cleaning mechanism 3 includes two sliding seats 301 slidably connected to one of the long rods 207, the end face of the sliding seat 301 is fixedly connected to the second motor 302, the output end of the second motor 302 is fixedly connected to the threaded rod 303, the arc surface of the threaded rod 303 is threadedly connected to the driving block 304, the end face of the driving block 304 is fixedly connected to the third motor 306, the output end of the third motor 306 is fixedly connected to the fixed rod 307, the arc surface of the fixed rod 307 is fixedly connected to the rectangular block 308, one end of the rectangular block 308 is fixedly connected to the fourth motor 309, and the output end of the fourth motor 309 is fixedly connected to the cleaning roller 310.

[0045] It should be noted that the two sliding seats 301 can be moved to a suitable position according to the inclination angle of the first conveyor belt 102, and the sliding seat 301 can be stabilized by inserting the clamping rod 312 into the clamping hole 313, so that the two cleaning rollers 310 and one round roller 210 will be evenly distributed inside the first conveyor belt 102, thereby avoiding the situation where the inclination angle of the first conveyor belt 102 is too large.

[0046] In an optional embodiment: the end surface of the sliding seat 301 is fixedly connected to the limiting rod 305 , and the end of the limiting rod 305 away from the sliding seat 301 slides through the driving block 304 .

[0047] It should be noted that when the driving block 304 moves, it will slide along the arc surface of the limiting rod 305 , and the driving block 304 plays a role in limiting the position of the driving block 304 , so as to avoid the driving block 304 from being offset as much as possible.

[0048] In an optional embodiment: the side wall of the sliding seat 301 is fixedly connected with a connecting plate 311, and the end face of the connecting plate 311 is slidably inserted with a clamping rod 312, and the arc surface of one of the long rods 207 is provided with a plurality of clamping holes 313, and the size of the clamping rod 312 is adapted to the size of the clamping hole 313, and the two cleaning rollers 310 are symmetrically distributed about the vertical center axis of the round roller 210, and the two cleaning rollers 310 are both located inside the first conveyor belt 102.

[0049] It should be noted that the sliding seat 301 is stabilized by inserting the clamping rod 312 into the clamping hole 313 .

[0050] In this embodiment, the movement of the sliding seat 301 can change the position of the round roller 210, thereby achieving the function of supporting the first conveyor belt 102. With the help of the drive of the threaded rod 303, the height of the cleaning roller 310 can be adjusted. Under the action of the two cleaning rollers 310, combined with the use of the round roller 210, the entire first conveyor belt 102 can be supported, that is, the first conveyor belt 102 can be prevented from tilting at too large an angle.

[0051] The working principle of the present invention is as follows: when in use, when the staff needs to adjust the angle of the first conveyor belt 102, the two electric telescopic rods 206 on one side of the first conveyor belt 102 are started to drive the two rectangular columns 101 to move upward, and the belt on the first conveyor belt 102 will be deformed and tilted, and it can stop when it reaches a suitable angle. At this time, the two sliding seats 301 can be moved, and the two sliding seats 301 are moved to a suitable position according to the tilt angle of the first conveyor belt 102, and the sliding seats 301 are stabilized by inserting the clamping rod 312 into the clamping hole 313, so that the two cleaning rollers 310 and the round roller 210 are evenly distributed inside the first conveyor belt 102, so as to avoid the first conveyor belt 102 from being damaged. If the belt 102 is tilted too much, the second motor 302 can be started to drive the threaded rod 303 to rotate, and the driving block 304 can be driven to move by the drive of the thread, that is, the cleaning roller 310 can be driven to move, and the belt on the first conveyor belt 102 can be appropriately tightened, so as to achieve the belt support of the first conveyor belt 102 and improve the support strength of the first conveyor belt 102 for the goods. Similarly, the sliding column 209 can be moved to move the round roller 210 to tighten the belt of the first conveyor belt 102. When the staff places the goods on the first conveyor belt 102 from a height, the first motor 202 is started to drive the rotating rod 203 to rotate, so that the second conveyor belt 205 rotates until it rotates to the position shown in FIG. Figure 3 The worker can then place the goods on the second conveyor belt 205 for transportation, and the goods will be automatically transported from the second conveyor belt 205 to the first conveyor belt 102;

[0052] When not in use, the third motor 306 can be started to drive the fixed rod 307 to rotate, that is, to adjust the angle of the cleaning roller 310 so that the cleaning roller 310 moves out from the inside of the first conveyor belt 102. After it is completely moved out, the second motor 302 is started to adjust the height of the cleaning roller 310 so that the cleaning roller 310 is higher than the first conveyor belt 102, and the third motor 306 is restarted to make the output shaft of the third motor 306 rotate in the opposite direction so that the bristles on the cleaning roller 310 can contact the first conveyor belt 102. At this time, the fourth motor 309 is started to drive the cleaning roller 310 to rotate. When the first conveyor belt 102 is transmitted, it will continuously contact the rotating cleaning roller 310 to achieve the cleaning of the first conveyor belt 102.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
