Description

Technical Field

[0001] This utility model relates to the field of maintenance equipment technology, and in particular to an unmanned transport vehicle inspection and maintenance device. Background Technology

[0002] Currently, in the manufacturing industry, in order to ensure the safety and reliability of AGV (Automated Guided Vehicle) operation, regular inspections and maintenance are required, usually once a month. Since the power components of the AGV are located at the bottom of the vehicle body, the AGV body needs to be rotated 90° during inspection and maintenance. However, the AGV weighs as much as 150kg, which makes it very inconvenient to carry out inspections and maintenance. Moreover, each time, two people are required to work together, which is time-consuming and labor-intensive.

[0003] Therefore, simplifying the inspection and maintenance of unmanned transport vehicles is an urgent problem that needs to be solved. Utility Model Content

The first threaded post is threadedly engaged with the first threaded hole, and the second threaded post is threadedly engaged with the second threaded hole, so that the first fastener and the second fastener can respectively abut against the two sides of the unmanned transport vehicle.

[0012] In one embodiment, the first drive assembly includes a first handle, a worm gear, and a worm. The worm and the worm gear are rotatably mounted on the frame. The worm meshes with the worm gear. The worm gear has an internal thread that is threaded to the screw.

[0013] In one embodiment, there are two screws, and the number of the first handle, the worm gear, the first support block, the second support block, the second drive assembly, and the arc-shaped guide rail is the same as the number of screws and they are arranged in a one-to-one correspondence.

[0014] In one embodiment, the second drive assembly includes a second handle, a drive shaft, and a gear. The drive shaft is tractably mounted on the frame. An arc-shaped rack is provided on the arc-shaped guide rail. The second handle is connected to the drive shaft.

[0015] In one embodiment, the number of the arc-shaped guide rails is two, and the number of the second handle, the gear, the first support block, the second support block, the first drive assembly, and the screw is the same as the number of the arc-shaped guide rails and they are arranged in a one-to-one correspondence.

[0016] In one embodiment, the bracket includes a mounting base, a positioning element, and a limiting element.

The first drive assembly can drive the rotating mechanism and the ARTV relative to the frame in a vertical direction by rotating the drive screw. The second drive assembly can drive the arc-shaped guide rail... The rotation of the support frame causes the automated guided vehicle (AGV) to rotate relative to the frame, allowing operators to easily adjust the position and attitude of the AGV using the first and second drive components. This simplifies the operation process, reduces the need for manual operation, facilitates the maintenance and upkeep of the AGV's internal structure, and eliminates the risk of injury from manual handling of the AGV. It also makes the inspection and maintenance of the AGV's internal structure faster, reduces maintenance time, and improves maintenance efficiency. Furthermore, through rapid and efficient inspection and maintenance, it can reduce the downtime of the AGV, thereby improving overall production efficiency. This utility model embodiment uses a lifting mechanism and a rotating mechanism to achieve the lifting and tilting of the unmanned transport vehicle (UGV), making the operation of the UGV during handling in a faulty state or during regular maintenance much simpler, reducing reliance on skilled personnel and lowering the operational difficulty. This UGV inspection and maintenance device provides a standardized tool and method process, transforming operations that originally relied on manual operation into operations using standardized tools, improving the consistency and predictability of operations. Operators can easily adjust the position and posture of the UGV through the first and second drive components, eliminating the manual handling and tilting operations that originally required two people to perform, and replacing them with mechanical devices. This reduces the number of operators, lowers labor costs, reduces the workload of operators, and improves work efficiency. Furthermore, the rotating mechanism allows the UGV to maintain an upright operation with a 90° tilt, eliminating the risk of tipping over and causing injury during maintenance operations, and ensuring the safety of operators.

[0035] Currently, in the manufacturing industry, in order to ensure the safety and reliability of unmanned transport vehicles (AGVs), regular inspections and maintenance are required, usually once a month. Since the power components of the AGV are located at the bottom of the vehicle body, the AGV body needs to be rotated 90° when it is inspected and maintained. However, the weight of the AGV is as high as 150kg, which makes it very inconvenient to inspect and maintain the AGV. Moreover, each inspection and maintenance requires two people to work together, which is time-consuming and labor-intensive.

[0036] After careful examination, the applicant discovered the following main problems during the inspection and maintenance of the automated guided vehicles:

[0037] ① Inconvenience of maintenance: Regular maintenance can only be carried out during production line downtime, requiring two people to move the AGV off the line and manually flip the AGV body. This is not only inefficient, but also carries the risk of injury from falling heavy objects.

[0038] ② Difficulty in handling emergencies: When an AGV malfunctions and cannot move during automatic operation, it is difficult to handle due to the lack of corresponding handling tools and standardized handling procedures. AGVs are heavy and carry components such as batteries, chains, and mechanical bearings. There is a risk of being caught or injured when manually flipping and pushing them. The operation efficiency is low and the workload is high.

[0039] ③ Safety issues: Two people are needed to push the AGV when it malfunctions, and two people are also needed to work together during maintenance, which increases the complexity of operation and safety risks;

[0040] ④ Efficiency and cost issues: Since the AGV weighs 1500kg and is inspected once a month, it requires two people to work together, which is not only inefficient, but also increases labor costs and operational risks.

[0041] The main purpose of this invention is to propose an inspection and maintenance device for unmanned transport vehicles to solve the problem of how to simplify the inspection and maintenance operations of unmanned transport vehicles.

[0042] Please see Figures 1 to 4 In one embodiment of this utility model, the unmanned transport vehicle inspection and maintenance device 100 includes a frame 1, a lifting mechanism 2, a rotating mechanism 3, a first drive assembly 4, and a second drive assembly 5. The lifting mechanism 2 includes a screw 21, and the rotating mechanism 3 includes a bracket 31 and a clamping assembly 32. The clamping assembly 32 includes a first bottom support block 321, a second bottom support block 322, and an arc-shaped guide rail 323. The second drive assembly 5 is connected to the bracket 31 and is drively connected to the arc-shaped guide rail 323. The bracket 31 and the arc-shaped guide rail 323 are in rolling engagement so that the second drive assembly 5 can drive the arc-shaped guide rail 323. The rail 323 rotates relative to the bracket 31; the first drive assembly 4 is connected to the frame 1 and is driven by the screw 21. The screw 21 is rotatably mounted on the bracket 31 so that the first drive assembly 4 can drive the arc-shaped guide rail 323 to move vertically relative to the frame 1 through the screw 21 and the bracket 31; the first bottom support block 321 and the second bottom support block 322 are respectively set at both ends of the arc-shaped guide rail 323. The arc-shaped guide rail 323 is provided with a through hole 3231 for the unmanned transport vehicle to pass through. The first bottom support block 321 and the second bottom support block 322 are both used to abut against the bottom of the unmanned transport vehicle.

[0043] In this embodiment of the utility model, the frame 1 supports the entire unmanned transport vehicle inspection and maintenance device 100. By setting the arc-shaped guide rail 323, the first support block 321, and the second support block 322, the unmanned transport vehicle can be supported. The through hole 3231 on the arc-shaped guide rail 323 allows unmanned transport vehicles of different sizes to pass through, making the unmanned transport vehicle inspection and maintenance device 100 highly adaptable and capable of serving various models of unmanned transport vehicles, effectively expanding the application range of the unmanned transport vehicle inspection and maintenance device 100. The first drive assembly 4 can drive the rotating mechanism 3 and the unmanned transport vehicle to rotate vertically relative to the frame 1 by rotating the drive screw 21. The second drive component 5 can rotate the unmanned transport vehicle relative to the frame 1 by driving the arc-shaped guide rail 323 to rotate relative to the bracket 31. This allows operators to easily adjust the position and posture of the unmanned transport vehicle through the first drive component 4 and the second drive component 5, simplifying the operation process, reducing the need for manual operation, and eliminating the risk of injury when manually handling the unmanned transport vehicle. It also makes the inspection and maintenance of the internal structure of the unmanned transport vehicle faster, reduces maintenance time, and improves the efficiency of maintenance work. Furthermore, through fast and efficient inspection and maintenance, it can also reduce the downtime of the unmanned transport vehicle, thereby improving the overall production efficiency.

[0044] The technical solution of this utility model uses a lifting mechanism 2 and a rotating mechanism 3 to realize the lifting and tilting of the unmanned transport vehicle, making the operation of the unmanned transport vehicle during handling or regular maintenance in a faulty state simpler, reducing reliance on skilled personnel and lowering the difficulty of operation. The unmanned transport vehicle inspection and maintenance device 100 provides a standardized tool and method process, transforming the original manual operation into operation using standardized tools, improving the consistency and predictability of the operation. Operators can easily adjust the position and posture of the unmanned transport vehicle through the first drive component 4 and the second drive component 5, eliminating the manual handling and tilting operations that originally required two people to cooperate, and replacing them with mechanical devices. This reduces the number of operators, lowers labor costs, reduces the workload of operators, and improves work efficiency. In addition, the rotating mechanism 3 also enables the unmanned transport vehicle to maintain a 90° tilted upright operation, eliminating the risk of tipping over and causing injury during maintenance operations, and ensuring the safety of operators.

[0045] In one embodiment, an opening 324 communicating with a through hole 3231 is formed between the first support block 321 and the second support block 322; and / or, the unmanned transport vehicle inspection and maintenance device 100 also includes casters 6, and the bottom of the frame 1 is provided with the casters 6; specifically, the bottom of the frame 1 is provided with casters 6, so that the entire unmanned transport vehicle inspection and maintenance device 100 can be easily moved to different work areas, improving the flexibility and efficiency of the work. The design of the opening 324 allows the unmanned transport vehicle to easily pass through the through hole 3231 to enter or leave the unmanned transport vehicle inspection and maintenance device 100, avoiding interference between the first support block 321 and the second support block 322 and the wheels at the bottom of the unmanned transport vehicle, improving the flexibility and efficiency of operation, simplifying the loading and unloading process of the unmanned transport vehicle, and the design of the opening 324 can adapt to unmanned transport vehicles of different sizes and shapes, improving the versatility and applicability of the unmanned transport vehicle inspection and maintenance device 100.

[0046] Please see Figure 5 and Figure 6 In one embodiment, the clamping assembly 32 further includes a positioning part 325, which includes a positioning plate 3251 and a positioning pin 3252. The positioning plate 3251 is connected to the arc-shaped guide rail 323. The positioning plate 3251 is provided with a mounting hole (not shown in the figure), and the positioning pin 3252 is used to pass through the mounting hole and the positioning hole on the unmanned transport vehicle. Specifically, by setting the positioning part 325, the position of the unmanned transport vehicle on the unmanned transport vehicle inspection and maintenance device 100 can be accurately determined, ensuring the accuracy and consistency of maintenance work. Moreover, through the design of the positioning plate 3251 and the positioning pin 3252, the unmanned transport vehicle can be quickly and accurately positioned, which can reduce the time spent by the operator on positioning the unmanned transport vehicle, thereby improving maintenance efficiency.

[0047] In one embodiment, the clamping assembly 32 further includes a first clamping portion 326 and a second clamping portion 327. The first clamping portion 326 includes a first pressing block 3261 and a first fastener 3262. The second clamping portion 327 includes a second pressing block 3271 and a second fastener 3272. The first pressing block 3261 and the second pressing block 3271 are disposed opposite to each other on the arc-shaped guide rail 323 along a first direction. The first pressing block 3261 is provided with a first threaded hole (not shown in the figure), the first fastener 3262 is provided with a first threaded post (not shown in the figure), the second pressing block 3271 is provided with a second threaded hole (not shown in the figure), and the second fastener 3272 is provided with a second threaded post (not shown in the figure). The first threaded post is threadedly engaged with the first threaded hole, and the second threaded post is threadedly engaged with the second threaded hole, so that the first fastener 3262 and the second fastener 3272 can respectively abut against the two sides of the unmanned transport vehicle. Specifically, the first The first clamping block 3261 and the second clamping block 3271 are arranged opposite each other on the arc-shaped guide rail 323 in the front-back direction, so that the first fastener 3262 and the second fastener 3272 can firmly clamp the two sides of the unmanned transport vehicle, ensuring the stability of the unmanned transport vehicle during lifting and rotation, preventing the unmanned transport vehicle from accidentally sliding or falling off during maintenance, and improving the safety of operation. Moreover, since the first threaded post is threadedly engaged with the first threaded hole and the second threaded post is threadedly engaged with the second threaded hole, the first fastener 3262 and the second fastener 3272 can adapt to unmanned transport vehicles of different widths, improving the versatility and adaptability of the first clamping part 326 and the second clamping part 327, and also facilitating operation. The clamping force of the first fastener 3262 and the second fastener 3272 on the unmanned transport vehicle can be precisely controlled to prevent it from being too tight or too loose, and to protect the unmanned transport vehicle from damage.

[0048] Please see Figure 7In one embodiment, the first drive assembly 4 includes a first handle 41, a worm gear 42, and a worm 43. The worm 43 and the worm gear 42 are rotatably mounted on the frame 1. The worm 43 meshes with the worm gear 42, and the worm gear 42 is provided with an internal thread that is threaded to the screw 21. The first handle 41 is connected to the worm 43 so that the first handle 41 can drive the screw 21 to move vertically relative to the frame 1 through the worm 43 and the worm gear 42. Specifically, the meshing of the worm 43 and the worm gear 42 can provide smooth and precise power transmission, making the vertical movement of the screw 21 more stable. The worm gear 42 and the worm 43 usually have a self-locking function, which can keep the screw 21 in its current position and prevent it from slipping due to gravity. This improves the safety, reliability, and efficiency of the unmanned transport vehicle inspection and maintenance device 100. By setting the first handle 41, the operator can drive the screw 21 to rise and fall with a simple rotation action. This operation method is simple, intuitive, and easy to learn. In this embodiment, the unmanned transport vehicle is equipped with wheels at the bottom, and the bottom of the unmanned transport vehicle is 50mm above the ground. When the unmanned transport vehicle malfunctions, the worm gear 43, worm wheel 42 and screw 21 are driven by the first handle 41, so that the height of the first support block 321 and the second support block 322 from the ground is less than 50mm. Then, the unmanned transport vehicle inspection and maintenance device 100 is pushed so that the unmanned transport vehicle can pass through the through hole 3231 on the arc guide rail 323, so that the first support block 321 and the second support block 322 can be located below the bottom of the unmanned transport vehicle. Then, by rotating the first handle 41, the first support block 321 and the second support block 322 are moved upward to abut against the bottom of the unmanned transport vehicle, thereby lifting the unmanned transport vehicle. This realizes the unmanned transport vehicle malfunction transportation without the need for manual pushing of the unmanned transport vehicle.

[0049] In this embodiment, to reduce the friction between the first support block 321 and the second support block 322 and the bottom of the unmanned transport vehicle when the unmanned transport vehicle inspection and maintenance device 100 moves, a first roller can be provided on the first support block 321 and a second roller can be provided on the second support block 322. Both the first roller and the second roller can roll relative to the bottom of the unmanned transport vehicle, thereby reducing the friction between the first support block 321 and the second support block 322 and the bottom of the unmanned transport vehicle and avoiding damage to the unmanned transport vehicle.

[0050] In one embodiment, there are two screws 21. The number of the first handle 41, worm gear 42, first support block 321, second support block 322, second drive assembly 5, and arc-shaped guide rail 323 are the same as the number of screws 21 and are arranged in a one-to-one correspondence. Specifically, the two screws 21 are spaced apart in the left-right direction, which can distribute the load, improve the load-bearing capacity of the entire unmanned transport vehicle inspection and maintenance device 100, ensure that the unmanned transport vehicle remains balanced during lifting, avoid tilting or deviation caused by uneven weight distribution, and ensure stability and safety when carrying heavy unmanned transport vehicles. In this embodiment, the two screws 21 share a worm gear 43, which can achieve precise synchronous control and ensure the smoothness and consistency of the unmanned transport vehicle during lifting.

[0051] According to one embodiment of the present invention, there are two screws 21, and the number of first drive components 4 is the same as the number of screws 21 and is set in a one-to-one correspondence. The two screws 21 are set in a one-to-one correspondence with the two first drive components 4. By setting two first drive components 4, the two screws 21 are driven to rotate respectively, thereby realizing the lifting of the unmanned transport vehicle.

[0052] Please see Figure 8 In one embodiment, the second drive assembly 5 includes a second handle 51, a drive shaft 52, and a gear 53. The drive shaft 52 is tractably mounted on the frame 1. An arc-shaped rack 3232 is provided on the arc-shaped guide rail 323. The second handle 51 is connected to the drive shaft 52. The gear 53 is sleeved on the outer wall of the drive shaft 52 and meshes with the arc-shaped rack 3232, so that the second handle 51 can drive the arc-shaped rack 3232 to move relative to the bracket 31 through the drive shaft 52 and the gear 53. Specifically, the gear 53 meshes with the arc-shaped rack 3232. The meshing provides smooth and precise power transmission, making the movement of the arc-shaped guide rail 323 more accurate and stable. Furthermore, the design of the gear 53 and the arc-shaped rack 3232 provides a self-locking function, ensuring the arc-shaped guide rail 323 remains in its current position and does not slip due to gravity. This improves the safety, reliability, and efficiency of the unmanned transport vehicle inspection and maintenance device 100. The second handle 51 allows the operator to drive the movement of the arc-shaped guide rail 323 with a simple rotational motion; this operation method is simple, intuitive, and easy to learn. In this embodiment, the rotation angle of the arc-shaped guide rail 323 is limited by the length of the arc-shaped rack 3232. The length of the arc-shaped rack 3232 can be selected according to actual needs; this embodiment does not impose a limitation on this.

[0053] In one embodiment, there are two arc-shaped guide rails 323. The number of the second handle 51, gear 53, first support block 321, second support block 322, first drive assembly 4, and screw 21 are the same as the number of arc-shaped guide rails 323 and are arranged in a one-to-one correspondence. Specifically, the two arc-shaped guide rails 323 are spaced apart in the left-right direction, which can evenly distribute the load on the two arc-shaped guide rails 323, reduce the burden on individual arc-shaped guide rails 323, improve the load-bearing capacity and durability of the entire unmanned transport vehicle inspection and maintenance device 100, and help maintain the balance and stability of the entire unmanned transport vehicle inspection and maintenance device 100. In this embodiment, the two arc-shaped guide rails 323 share a drive shaft 52, which can achieve precise synchronous control and ensure the smoothness and consistency of the unmanned transport vehicle during rotation.

[0054] According to one embodiment of the present invention, there are two arc-shaped guide rails 323, and the number of second drive components 5 is the same as the number of arc-shaped guide rails 323 and is set in a one-to-one correspondence. The two arc-shaped guide rails 323 and the two second drive components 5 are set in a one-to-one correspondence. By setting two second drive components 5, the two arc-shaped guide rails 323 are driven to rotate respectively, thereby realizing the rotation of the unmanned transport vehicle.

[0055] Please see Figure 1 , Figure 5 and Figure 9In one embodiment, the bracket 31 includes a mounting base 311, a positioning member 312, and a limiting member 313. The positioning member 312 and the limiting member 313 are located on the inner and outer sides of the arc-shaped guide rail 323, respectively. The positioning member 312 includes a first bearing 3121 and a second bearing 3122, and the limiting member 313 includes a third bearing 3131 and a fourth bearing 3132. The screw 21 is rotatably mounted on the mounting base 311. The first bearing 3121, the second bearing 3122, and the third bearing 3131 are... Both bearing 31 and the fourth bearing 3132 are connected to the mounting base 311. The first bearing 3121 and the second bearing 3122 are spaced apart along the extending direction of the mounting base 311, and the third bearing 3131 and the fourth bearing 3132 are spaced apart along the extending direction of the mounting base 311. The first bearing 3121 and the third bearing 3131 are spaced apart vertically. The first bearing 3121 and the second bearing 3122 roll in contact with the inner side of the arc-shaped guide rail 323. The third bearing 3131 and the fourth bearing 3132 are... Four bearings 3132 are disposed on the outer side of the arc-shaped guide rail 323. Specifically, the first bearing 3121 and the second bearing 3122 are spaced apart along the extension direction of the mounting base 311, which helps to ensure the precise positioning of the arc-shaped guide rail 323 during movement. The first bearing 3121 and the second bearing 3122 roll with the inner side of the arc-shaped guide rail 323, which can reduce friction and make the movement of the arc-shaped guide rail 323 smoother and more efficient. The third bearing 3131 and the fourth bearing 3132 are also spaced apart along the extension direction of the mounting base 311, and the third bearing 3131 and the fourth bearing 3132 are disposed on the outer side of the arc-shaped guide rail 323. They can work with the first bearing 3121 and the second bearing 3122 to limit the movement range of the arc-shaped guide rail 323, prevent the arc-shaped guide rail 323 from moving excessively, enhance the stability of the entire unmanned transport vehicle inspection and maintenance device 100, ensure that the arc-shaped guide rail 323 does not exceed the predetermined safety range during movement, and improve the safety of operation.

[0056] In this embodiment, there are two of each of the following bearings: the first bearing 3121, the second bearing 3122, the third bearing 3131, and the fourth bearing 3132. Each of these bearings is arranged in a one-to-one correspondence and is positioned on both sides of the arc-shaped guide rail 323 along its axial direction. This increases the structural strength of the rotating mechanism 3, reduces deformation caused by load or external force, and provides balanced support for the arc-shaped guide rail 323, ensuring the stability and balance of the arc-shaped guide rail 323 and the unmanned transport vehicle during movement.

[0057] In one embodiment, a linear slide rail 11 is provided on the frame 1, extending vertically. A linear slider 314 is provided on the bracket 31, slidingly engaging with the linear slide rail 11. A first limiting hole (not shown) is provided on the linear slider 314, and a second limiting hole 111 is provided on the linear slide rail 11. Multiple second limiting holes 111 are provided, spaced apart along the extending direction of the linear slide rail 11. The unmanned transport vehicle inspection and maintenance device 100 also includes a limiting pin 7. 7. The linear slider 314 moves relative to the linear slide rail 11 by passing through the first limiting hole and the second limiting hole 111. Specifically, the sliding cooperation between the linear slide rail 11 and the linear slider 314 can achieve precise positioning of the bracket 31 in the vertical direction, ensuring the stability of the unmanned transport vehicle during inspection and maintenance. The positioning pin 3252, as a safety protection mechanism, provides additional safety protection, preventing the unmanned transport vehicle from accidentally sliding down under gravity, improving the safety of operation, and ensuring the stability and reliability of the lifting mechanism 2.
