Description

Technical Field

[0001] The invention relates to the field of cargo transportation, and in particular to an adjustable logistics cargo transportation device. Background Art

[0002] Logistics is the process of ensuring that goods are transferred from one location to another in a safe, timely and cost-effective manner. Logistics goods usually need to be transported by means of transportation, such as trains, trucks, airplanes, etc. When loading logistics goods piled up in warehouses, in order to save time and manpower, corresponding conveying equipment is also needed to assist in completing the loading operation of goods.

[0003] When loading bagged materials, the existing conveying devices usually move the movable conveying equipment between the truck and the bagged material pile, limit the conveying equipment, then adjust the conveying distance and conveying height of the conveying equipment, start the conveying equipment, manually place the bagged materials on the conveying equipment, and the conveying equipment conveys the bagged materials to the truck. However, the support module of the existing movable conveying equipment is usually a rigid structure. When heavier bagged materials fall onto the conveying equipment, the conveying equipment cannot cushion the instantaneous impact caused by the falling of the bagged materials. The impact of the bagged materials on the conveying equipment for long-distance transportation will cause the deformation of the support module of the conveying equipment to increase and cause up and down shaking, which will easily cause the bagged materials to fall off the conveying equipment, thereby reducing the stability and efficiency of the bagged material transportation and reducing the service life of the conveying equipment.

When the conveying component 41 moves to the working position, the positioning rod 4333 is inserted into the support frame 1 and engaged with the corresponding positioning hole 4332 to realize the function of limiting the rotating arc plate 4331, thereby limiting the adjusted conveying component 41.

[0039] See also Figure 1 , Figure 2 and Figure 5 The conveying component 41 includes a supporting assembly 411 arranged on the left and right sides of the supporting column 31, the supporting assembly 411 is connected between the two circular plates 32, and a conveying belt 412 is commonly connected between the two supporting assemblies 411.

[0040] See also Figure 1 , Figure 2 and Figure 5 The support assembly 411 includes two waist-shaped plates 4111 which are symmetrically distributed between the two circular plates 32. A plurality of evenly distributed transmission rollers 4112 are rotatably connected between the two waist-shaped plates 4111. The transmission rollers 4112 are rotatably connected to the conveyor belt 412. Connecting columns 4113 are installed on the opposite ends of the two waist-shaped plates 4111, close to the circular plates 32.

[0041] During specific operation, when the rotating arc plate 4331 moves, it drives the columnar rod 4114 to rotate through the buffer component 42. The columnar rod 4114 drives the two waist-shaped plates 4111 to rotate with the connecting column 4113 as the axis. The two waist-shaped plates 4111 drive multiple transmission rollers 4112 to move, thereby driving the conveyor belt 412 to move. After the multiple transmission rollers 4112 on both sides adjust the two sides of the conveyor belt 412, the rotating arc plate 4331 is limited by the positioning rod 4333.

[0042] See also Figure 1 , Figure 2 and Figure 5The circular plate 32 is provided with a sliding through hole 33, and a tensioning component 34 is commonly connected to the two sliding through holes 33. The tensioning component 34 includes two sliding blocks 341 respectively slidably connected to the two sliding through holes 33, and a tensioning roller 342 is commonly rotatably connected between the two sliding blocks 341. A U-shaped plate 343 with an upward opening is commonly installed at the lower ends of the two sliding blocks 341. The two vertical sections of the U-shaped plate 343 are respectively slidably penetrated and matched with the two circular plates 32. An adjusting screw 344 is threadedly connected to the horizontal section of the U-shaped plate 343. The upper end of the adjusting screw 344 is rotatably connected to the support frame 1. The middle part of the conveyor belt 412 is located between the support column 31 and the tensioning roller 342.

[0043] During specific operation, the tensioning roller 342 is initially located between the two circular plates 32 near the upper side. After the two sides of the conveyor belt 412 are adjusted to the desired position (i.e., after the waist-shaped plate 4111 is rotated to the desired angle), the adjusting screw 344 is rotated, and the adjusting screw 344 drives the U-shaped plate 343 to move downward. The U-shaped plate 343 drives the two sliding blocks 341 to slide in the two sliding through holes 33. The two sliding blocks 341 drive the tensioning roller 342 to move downward and press down the conveyor belt 412, so that the conveyor belt 412 is in a tensioned state.

[0044] See also Figure 1 , Figure 2 , Figure 5 and Figure 6 The buffer component 42 includes a first U-shaped frame 421 connected to the conveying component 41 and opening upward, the columnar rod 4114 is rotatably connected between the two vertical sections of the first U-shaped frame 421, and a plurality of evenly distributed cylindrical rods 422 are installed at the lower end of the first U-shaped frame 421. The outer periphery of the cylindrical rod 422 is provided with a first spring 423 fixedly connected to the lower end of the first U-shaped frame 421, and a rectangular plate 424 is commonly installed at the lower ends of the plurality of first springs 423. The rectangular plate 424 is fixedly connected to the corresponding fixing bar 431 at one end close to the support column 31.

[0045] See also Figure 1 , Figure 2 , Figure 5 and Figure 6 The adjustable logistics cargo conveying device also includes a guiding unit 5, which is connected to any one of the rectangular plates 424. The guiding unit 5 includes two L-shaped plates 51 installed at the front and rear ends of the rectangular plate 424. A rotating rod 52 is passed through and rotatably connected to the vertical section of the L-shaped plate 51 near the upper end. A second U-shaped frame 53 with an opening facing upward is installed between the two rotating rods 52. The middle section of the second U-shaped frame 53 is connected to a guiding component 54, and the end of the rotating rod 52 away from the second U-shaped frame 53 is connected to a limiting component 55.

[0046] During specific operation, when the rotating arc plate 4331 drives the fixed bar 431 to move by driving the fixed plate 432, the fixed bar 431 drives the rectangular plate 424 to rotate, and the rectangular plate 424 drives the two L-shaped plates 51 to move. The two L-shaped plates 51 drive the second U-shaped frame 53 to move to the bottom of the existing bagged material output end through the two rotating rods 52, and the second U-shaped frame 53 drives the guide component 54 to move to the bottom of the existing bagged material output end.

[0047] See also Figure 1 , Figure 5 and Figure 6 The guide component 54 includes a plurality of lifting rods 541 that are evenly distributed and slidably connected to the middle section of the second U-shaped frame 53. A lifting plate 542 is commonly installed on the upper ends of the plurality of lifting rods 541. A plurality of evenly distributed cylindrical rollers 543 are rotatably connected to the upper end of the lifting plate 542. A right-angled triangular plate 544 with an inclined surface facing upward is hinged on the upper side of one end of the lifting plate 542 close to the support column 31. A plurality of second springs 545 distributed in a rectangular shape are installed between the lower end of the lifting plate 542 and the middle section of the second U-shaped frame 53.

[0048] See also Figure 1 , Figure 5 and Figure 6 The limiting component 55 includes a limiting plate 551 installed at the end of the rotating rod 52 away from the second U-shaped frame 53, and a plurality of limiting holes 552 evenly distributed in the circumferential direction are opened on the limiting plate 551. Any plurality of the limiting holes 552 are inserted into limiting rods 553, and the limiting rods 553 are plugged into and matched with the corresponding vertical sections of the L-shaped plate 51. An arc plate 554 is commonly installed at one end of the plurality of limiting rods 553 on the same side away from the vertical section of the L-shaped plate 51.

[0049] In specific operation, when the second U-shaped frame 53 moves, the lifting plate 542 is driven to move by the plurality of second springs 545. When the second U-shaped frame 53 moves to the desired position, the limit plate 551 is rotated, and the limit plate 551 drives the second U-shaped frame 53 to rotate. The second U-shaped frame 53 drives the lifting plate 542 to rotate to a state of tilting to the lower right (with a plurality of lifting rods 541) through the plurality of lifting rods 541. Figure 1For example, the lifting plate 542 drives the hinged right-angled triangle plate 544 to rotate to the upper end of the conveyor belt 412, and then drives multiple limiting rods 553 to be inserted into the corresponding limiting holes 552 through the arc plate 554 and plugged into the vertical section of the L-shaped plate 51, thereby realizing the function of limiting the rotated second U-shaped frame 53. Multiple second springs 545 cooperate with the lifting plate 542 to fully absorb the potential energy generated by the falling of the bagged material, effectively preventing the support component 411 from being severely bent due to instantaneous strong impact, avoiding damage to the conveying device, and at the same time avoiding the support component 411 from shaking up and down, thereby improving the stability of bagged material transportation.

[0050] See also Figure 1 , Figure 2 , Figure 5 and Figure 6 The rectangular plate 424 is provided with a plurality of rectangular through holes 425 , and the plurality of rectangular through holes 425 correspond one-to-one to the plurality of cylindrical rods 422 . The buffer component 42 further includes a plurality of pitch-adjusting screws 426 threadedly connected to the rectangular plate 424 .

[0051] During operation, the plurality of pitch-adjusting screws 426 corresponding to the working end of the conveyor belt 412 are rotated to make them close to the lower end of the corresponding first U-shaped frame 421, so that the support assembly 411 corresponding to the working end of the conveyor belt 412 is in a rigid state and does not rotate downward under pressure. Then, according to the weight of the bagged material, the plurality of pitch-adjusting screws 426 corresponding to the working initial end of the conveyor belt 412 are rotated to change the distance between them and the corresponding first U-shaped frame 421, so as to avoid excessive rotation of the support assembly 411 corresponding to the working initial end of the conveyor belt 412, thereby avoiding damage to the conveyor belt 412. After the angle adjustment of the second U-shaped frame 53 is completed, the existing motor is connected to the columnar rod 4114 away from the L-shaped plate 51, and then the existing motor is started. The existing motor drives the columnar rod 4114 to rotate, and the columnar rod 4114 drives the conveyor belt 412 to rotate through the corresponding transmission roller 4112, and the transmission belt 412 drives multiple transmission rollers 4112 to rotate, and then the existing bagged material output end conveys the bagged material to the lifting plate 542, and multiple second springs 545 cushion the falling bagged material through the lifting plate 542, reducing the instantaneous impact force generated when it falls, thereby avoiding The bagged materials are not in direct contact with the conveyor belt 412, which effectively avoids the impact and damage of the bagged materials on the conveyor belt 412, ensures the working stability of the conveyor belt 412, and improves the service life of the conveying device. The bagged materials that fall onto the lifting plate 542 move on multiple cylindrical rollers 543 to the rotating conveyor belt 412 under inertia. The conveyor belt 412 is forced to drive the two waist-shaped plates 4111 to move downward through multiple transmission rollers 4112. The two waist-shaped plates 4111 drive the corresponding first U-shaped frame 421 to move downward through the corresponding columnar rods 4114. The first U-shaped frame 421 drives multiple cylindrical rods 422 moves in the plurality of rectangular through holes 425, causing the first spring 423 to expand and contract, and then the plurality of first springs 423 further realize the function of buffering the conveying of the bagged materials, reducing the impact of the bagged materials on the entire device when they fall onto the conveyor belt 412, and also avoiding the shaking of the conveyor belt 412 when the bagged materials fall onto the conveyor belt 412. Subsequently, the rotating conveyor belt 412 conveys the bagged materials to the other end, and the bagged materials are separated from the conveyor belt 412 and moved to the truck, and the conveying of the bagged materials is continued until the required amount of bagged materials is fully conveyed.
