Description

Technical Field

[0001] The utility model relates to the field of AGV equipment, in particular to a latent traction type AGV equipment. Background Art

[0002] An AGV vehicle refers to a transport vehicle equipped with automatic navigation devices such as electromagnetic or optical ones, capable of traveling along a specified navigation path, having safety protection and various load-carrying functions. In industrial applications, it is a forklift truck that does not require a driver, and its power source is a rechargeable battery. Generally, its traveling path and behavior can be controlled by a computer, or an electromagnetic track can be used to set up its traveling path. The electromagnetic track is adhered to the floor, and the driverless transport vehicle moves and operates relying on the information brought by the electromagnetic track. The latent traction type AGV utilizes a traction bolt. When the AGV cart travels under the goods rack, the traction bolt can rise to fix the goods rack, and the goods rack moves along with the traction of the cart. The maximum traction weight of the latent traction type AGV is 1.5 tons. AGVs with different load capacities and different traction methods can be customized according to requirements.

[0003] After retrieval, a two-way latent traction type AGV logistics vehicle with the publication number of CN218641748U includes a chassis. A vehicle body is arranged on the top of the chassis. Support seats are vertically arranged at the four corners of the bottom of the chassis. Wheels are hinged on one side of each support seat close to the center direction of the chassis. A two-way drive assembly for controlling the rotation of the wheels is arranged at the center position of the top of the chassis. Hydraulic traction assemblies are arranged at both ends of the top of the chassis. L-shaped rods are symmetrically arranged on both side surfaces at both ends of the chassis. A linkage cleaning assembly for cleaning obstacles for the wheels is arranged at the bottom of the L-shaped rod. By using the two-way drive assembly and the linkage cleaning assembly in cooperation, the utility model can, while the AGV vehicle is running, remove the obstacles on the road surface through the cleaning disc arranged in front of the running direction, effectively improving the running stability of the AGV vehicle and reducing the occurrence of the situation where goods are jolted and spilled.

[0004] The above-mentioned linkage cleaning assembly includes rotating rods rotatably inserted into the ends of the L-shaped rods far from the chassis. Cleaning discs are horizontally sleeved at the bottoms of the rotating rods. The bottoms of the cleaning discs are all located in the same plane. After long-term use, a large amount of dust will adhere to the inside of the cleaning discs. Therefore, it is necessary to regularly disassemble the cleaning discs for cleaning and replacement. It is rather inconvenient to disassemble such cleaning discs. Moreover, since the bottoms of the cleaning discs are all located in the same plane and the entire bottom of the cleaning disc is in contact with the ground, when cleaning, the bottom of the cleaning disc will drive some obstacles to move in a circular motion, resulting in insufficient cleaning of the obstacles and possibly causing the obstacles to move around and return to their original positions.

[0005] Therefore, it is necessary to provide a new latent traction type AGV equipment to solve the above technical problems. Summary of the Utility Model

Two driving grooves are respectively formed on both sides of the inner wall of the driving block. The four driving columns are respectively located in the four driving grooves. The top of the driving block is fixedly connected with the bottom end of the pressing column.

[0011] Preferably, the linkage member includes a first bevel gear, a second bevel gear and a first rotating rod. Two first supporting blocks are fixedly arranged on one side of the vehicle frame.

[0015] Compared with the related technologies, the latent traction type AGV device provided by the present utility model has the following beneficial effects:

[0016] 1. When it is necessary to disassemble the cleaning disk, by pressing the top end of the pressing column, the pressing column descends. The pressing column will push the driving block to descend. When the driving block descends, the inner wall of the driving groove squeezes the surface of the driving column, so that the driving column drives the clamping block to move, making the two clamping blocks approach relatively and compressing the spring. When the two clamping blocks approach relatively, they will respectively disengage from the two clamping slots, so that the cleaning disk loses its limit, and the cleaning disk can be removed. And by shortening the overall length of the telescopic column, the cleaning disk is moved away from the inside, making it more convenient to disassemble the cleaning disk.

[0017] 2. The cleaning disk is inclined, and the bottom of the cleaning disk is spherical. When cleaning the road surface, because the bottom of the cleaning disk is spherical and has a certain inclination angle, when the cleaning disk rotates, the contact time between the same position of the bottom of the cleaning disk and the ground is short and it does not always contact the ground. Therefore, the obstacles on the road surface can be swept to one side, but the obstacles will not be driven to move in a circular motion. Therefore, to a certain extent, the cleaning degree of the cleaning disk for cleaning obstacles can be improved. And by controlling the overall length of the telescopic column, the contact degree between the cleaning disk and the ground can be controlled to make the cleaning cleaner.

[0029] Please refer to Figures 1 - 9 , where Figure 1 is the overall structural schematic diagram of the latent traction type AGV device provided by the present utility model Figure 1 ; Figure 2 is the overall structural schematic diagram of the latent traction type AGV device provided by the present utility model Figure 2 ; Figure 3 is Figure 1 the internal structural schematic diagram of the vehicle frame shown in Figure 4 is Figure 2 the overall structural schematic diagram of the linkage shown in Figure 5 is Figure 1 the partial structural schematic diagram of the cleaning component shown in Figure 6 is Figure 5 the sectional structural schematic diagram of the cleaning component shown in Figure 7 is Figure 6 the enlarged structural schematic diagram of A shown in Figure 8 is Figure 6 the enlarged structural schematic diagram of B shown in Figure 9 is Figure 6 the overall structural schematic diagram of the engaging component shown in

[0030] In the specific implementation process, such as Figures 1 - 9As shown in the figure, a latent traction type AGV device includes a vehicle frame 1. On both sides of the bottom inside wall of the vehicle frame 1, traction components are respectively provided. The traction components are used for fixing the material box. At both ends of the bottom of the vehicle frame 1, fixed seats 2 are respectively provided. Two wheels 3 are arranged inside the fixed seats 2. One side of each of the two wheels 3 is rotatably connected to both sides of the inner wall of the fixed seat 2. A rotating column 4 is arranged between the two wheels 3. Both ends of the rotating column 4 are fixedly connected to the opposite sides of the two wheels 3. A driving component is provided at the bottom of the vehicle frame 1. The driving component is used for driving the rotating column 4 to rotate. Cleaning components are respectively provided at both ends of the vehicle frame 1. The cleaning components are used for cleaning the road surface in the advancing direction of the wheels 3. The cleaning components are connected to the surface of the rotating column 4 through linkage parts;

[0031] The cleaning component includes two fixed frames 5 fixedly arranged on one side of the vehicle frame 1. Through holes are respectively opened at the bottoms of the two fixed frames 5. Telescopic columns are respectively arranged in the two through holes. The side surfaces of the two telescopic columns are respectively rotatably connected to the inner walls of the two through holes. Cleaning discs 6 are respectively sleeved at the bottoms of the two telescopic columns. A clamping component is arranged inside the telescopic columns. A fixed groove 7 is arranged at the top of the cleaning disc 6. Two clamping grooves 8 are arranged on the inner side wall of the fixed groove 7. Both ends of the clamping component penetrate through the inner wall of the telescopic column and are respectively clamped with the two clamping grooves 8. The cleaning disc 6 is arranged in an inclined manner. The bottom of the cleaning disc 6 is spherical. When cleaning the road surface, since the bottom of the cleaning disc 6 is spherical and has a certain inclination angle, when the cleaning disc 6 rotates, the contact time between the same position of the bottom of the cleaning disc 6 and the ground is short and it does not always contact the ground. Thus, the obstacles on the road surface can be swept to one side, but the obstacles will not be driven to move in a circular motion, avoiding the obstacles rotating one week and returning to the original position. When it is necessary to disassemble the cleaning disc 6, by controlling the clamping component, the two ends of the clamping component can be conveniently separated from the two clamping grooves 8, so that the cleaning disc 6 loses its limit and the cleaning disc 6 can be removed;

[0032] As Figures 5 - 8As shown in the figure, the telescopic column includes a fixed column 9, a lifting sleeve 10, and a threaded rod 11. The surface of the fixed column 9 is rotatably connected to the inner wall of the through hole. The top end of the lifting sleeve 10 is slidably sleeved on the bottom end of the fixed column 9. A plurality of first limiting grooves are provided on the inner side wall of the lifting sleeve 10. A plurality of first limiting blocks 12 matching the first limiting grooves are provided on the surface of the fixed column 9. The plurality of first limiting blocks 12 are respectively located in the plurality of first limiting grooves. A threaded sleeve 13 is fixedly provided inside the lifting sleeve 10. The top end of the threaded sleeve 13 is threadedly sleeved on the bottom end of the threaded rod 11. The top end of the threaded rod 11 movably penetrates the bottom end of the fixed column 9. The surface of the threaded rod 11 is rotatably connected to the inner wall of the fixed column 9. The bottom end of the lifting sleeve 10 is located in the fixed groove 7. A nut is sleeved on the top end of the threaded rod 11, which is convenient for rotating the threaded rod 11. By rotating the threaded rod 11, the threaded sleeve 13 connected to the bottom end of the threaded rod 11 is driven to rise or fall, so that the lifting sleeve 10 rises or falls. The rise or fall of the lifting sleeve 10 will drive the cleaning disc 6 to rise or fall, thereby controlling the height of the cleaning disc 6;

[0033] As Figure 5 , Figure 6 and Figure 9 shown in the figure, the engaging component includes two clamping blocks 14, a driving block 15, a spring 16, and a pressing column 17. One end of the two clamping blocks 14 penetrates the inner wall of the lifting sleeve 10 and is respectively engaged with the two clamping grooves 8. Grooves are respectively provided at the opposite ends of the two clamping blocks 14. The two ends of the spring 16 are respectively located in the two grooves and are respectively fixedly connected to one side of the inner walls of the two grooves. Limiting plates 18 are respectively provided at the top and bottom of the clamping block 14. Both ends of the two limiting plates 18 are fixedly connected to the inner wall of the lifting sleeve 10. Two driving columns 19 are respectively provided on both sides of the two clamping blocks 14. The driving block 15 is in a "П" shape. Two driving grooves 20 are respectively provided on both sides of the inner wall of the driving block 15. The four driving columns 19 are respectively located in the four driving grooves 20. The top of the driving block 15 is fixedly connected to the bottom end of the pressing column 17. The top end of the pressing column 17 sequentially movably penetrates the bottom of the threaded sleeve 13 and the bottom of the threaded rod 11. Press the top end of the pressing column 17 to make the pressing column 17 descend. The pressing column 17 will push the driving block 15 to descend. The descent of the driving block 15 squeezes the surface of the driving column 19 through the inner wall of the driving groove 20, so that the driving column 19 drives the clamping block 14 to move, making the two clamping blocks 14 approach each other relatively and compressing the spring 16. The relative approach of the two clamping blocks 14 will respectively disengage from the two clamping grooves 8, so that the cleaning disc 6 loses its limit and the cleaning disc 6 can be removed. Two second limiting grooves are provided on the inner side wall of the fixed groove 7. Two second limiting blocks are provided on the side surface of the lifting sleeve 10. The two second limiting blocks are respectively located in the two second limiting grooves;

[0034] As Figure 4As shown, the linkage member includes a first bevel gear 21, a second bevel gear 22, and a first rotating rod 23. Two first support blocks 24 are fixedly provided on one side of the vehicle frame 1. The surface of the first rotating rod 23 is rotatably connected to the inside of the two first support blocks 24. One side of the first bevel gear 21 is fixedly connected to one end of the first rotating rod 23. The second bevel gear 22 is fixedly sleeved on the surface of the fixed column 9. The first bevel gear 21 meshes with the second bevel gear 22. A driving wheel 25 is fixedly sleeved on the surface of the rotating column 4. A driven wheel 26 is sleeved on the surface of the first rotating rod 23. The driving wheel 25 and the driven wheel 26 are connected by a transmission belt 27. By rotating the rotating column 4, when the rotating column 4 rotates, the first rotating rod 23 can be driven to rotate through the driving wheel 25, the transmission belt 27, and the driven wheel 26. The first rotating rod 23 then drives the first bevel gear 21 to rotate. The first bevel gear 21 drives the fixed column 9 to rotate through the meshing second bevel gear 22;

[0035] As Figures 1 - 4 shown, the driving assembly includes a second rotating rod 29, a first helical gear 30, and a second helical gear 31. Two second support blocks 32 are fixedly provided at the bottom of the vehicle frame 1. The two ends of the second rotating rod 29 respectively pass through the opposite sides of the two second support blocks 32 movably. The surface of the second rotating rod 29 is rotatably connected to the inside of the two second support blocks 32. A motor 28 is fixedly installed at the bottom of the inner wall of the vehicle frame 1. The output end of the motor 28 is fixedly connected to one side of the first helical gear 30. The second helical gear 31 is fixedly sleeved on the surface of the second rotating rod 29. The first helical gear 30 meshes with the second helical gear 31. One end of the second rotating rod 29 is fixedly provided with a third bevel gear 33. A fourth bevel gear 34 is fixedly provided on the surface of the rotating column 4. The third bevel gear 33 meshes with the fourth bevel gear 34. By starting the motor 28, the motor 28 drives the first helical gear 30 to rotate. The first helical gear 30 drives the second rotating rod 29 to rotate through the meshing second helical gear 31. The rotation of the second rotating rod 29 drives the third bevel gear 33 to rotate. The third bevel gear 33 drives the rotating column 4 to rotate through the fourth bevel gear 34. The rotation of the rotating column 4 drives the wheel 3 to rotate;

[0036] As Figure 1 and Figure 3 shown, the traction assembly includes a hydraulic cylinder 35 and a traction bolt 36. The bottom of the hydraulic cylinder 35 is fixedly connected to the bottom of the inner wall of the vehicle frame 1. The output point of the hydraulic cylinder 35 is fixedly connected to the bottom end of the traction bolt 36. The top end of the traction bolt 36 movably passes through the top of the inner wall of the vehicle frame 1 and extends to the outside of the vehicle frame 1. Starting the hydraulic cylinder 35 causes the traction bolt 36 to rise, so that the traction bolt 36 catches the material box on the top of the vehicle frame 1 to fix the material box.

[0037] The working principle provided by the present utility model is as follows: When in use, the traction bolt 36 is lifted by starting the hydraulic cylinder 35, and the traction bolt 36 is used to clamp the material box at the top of the vehicle frame 1 to fix the material box. By starting the motor 28, the motor 28 drives the first bevel gear 30 to rotate. The first bevel gear 30 drives the second rotating rod 29 to rotate through the engaged second bevel gear 31. The rotation of the second rotating rod 29 drives the third bevel gear 33 to rotate. The third bevel gear 33 drives the rotating column 4 to rotate through the fourth bevel gear 34. The rotation of the rotating column 4 drives the wheels 3 to rotate, so that the vehicle frame 1 can move to transport materials. When the rotating column 4 rotates, the first rotating rod 23 can be driven to rotate through the driving wheel 25, the transmission belt 27 and the driven wheel 26. The first rotating rod 23 then drives the first bevel gear 21 to rotate. The first bevel gear 21 drives the fixed column 9 to rotate through the engaged second bevel gear 22. The fixed column 9 is matched with a plurality of limiting grooves and limiting blocks, so that the lifting sleeve 10 rotates. The rotation of the lifting sleeve 10 is matched with two second limiting grooves and second limiting blocks, so that the cleaning disk 6 rotates. The rotation of the cleaning disk 6 can clean the obstacles on the road surface in the advancing direction of the wheels 3.

[0038] When the cleaning disk 6 needs to be disassembled, by pressing the top end of the pressing column 17, the pressing column 17 descends. The pressing column 17 will push the driving block 15 to descend. The descent of the driving block 15 squeezes the surface of the driving column 19 through the inner wall of the driving groove 20, so that the driving column 19 drives the clamping block 14 to move, making the two clamping blocks 14 approach each other relatively and compress the spring 16. The relative approach of the two clamping blocks 14 will respectively disengage from the two clamping grooves 8, so that the cleaning disk 6 loses its limit and the cleaning disk 6 can be removed.

[0039] Before disassembling the cleaning disk 6, by rotating the threaded rod 11, the threaded sleeve 13 connected to the bottom end of the threaded rod 11 is driven to rise, so that the lifting sleeve 10 rises. The rise of the lifting sleeve 10 will drive the cleaning disk 6 to rise, so that the cleaning disk 6 is far away from the ground, which is more convenient for disassembling the cleaning disk 6. In addition, the above structure can control the contact degree between the cleaning disk 6 and the ground, so that the cleaning is cleaner.

[0040] The circuits and controls involved in the present utility model are all prior arts and will not be elaborated here.

[0041] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present utility model.
