Description

Technical Field

[0001] This utility model relates to the field of operational technology, and in particular to a guide vehicle maintenance platform. Background Technology

[0002] AGVs (Automated Guided Vehicles) are transportation devices that operate autonomously in industrial environments using automated navigation systems (such as laser guidance, magnetic strip guidance, or visual navigation). They are widely used in factories, warehouses, logistics centers, and other settings for tasks such as material handling and cargo transportation.

[0003] AGVs are crucial nodes in factory logistics systems. AGVs are relatively heavy, and their bottom clearance is small, typically around 2cm, making bottom maintenance extremely difficult when an AGV malfunctions. Current methods primarily employ side-folding maintenance, ground-level recessed maintenance, or top-mounted maintenance.

[0004] The current top-mounted maintenance method requires the AGV to be sent to the maintenance platform first. The AGV maintenance platform fixes the AGV with clamps, then lifts it to a certain height, places it on a high platform for secondary fixation, and then performs maintenance on the bottom of the AGV. This results in a more complex structure and higher cost for the maintenance platform. Utility Model Content

[0008] The frame is provided with lifting components on both sides along the first direction, corresponding to the maintenance station. The lifting end of the lifting component is provided with a lifting arm.

[0009] The lifting assembly lowers the lifting arm to a designated position on the guide vehicle, causing the guide vehicle to rotate so that the lifting arm inserts into the guide vehicle and forms a rigid engagement structure, allowing the lifting assembly to drive the guide vehicle to perform linear lifting motion via the lifting arm.

[0045] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present utility model, and does not imply that every embodiment of the present utility model must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0046] The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0047] In some embodiments, such as Figure 1 As shown, this utility model proposes a guide vehicle maintenance platform, comprising:

[0048] The frame 10 is provided with a maintenance bay (not shown, same throughout) for placing the guide vehicle 20;

[0049] The frame 10 is provided with lifting components 30 on both sides of the maintenance station along the first direction, and the lifting end of the lifting component 30 is provided with a lifting arm 301.

[0050] The lifting assembly 30 drives the lifting arm 301 to descend to the designated position of the guide vehicle 20, and the guide vehicle 20 rotates so that the lifting arm 301 is inserted into the guide vehicle 20 and forms a rigid engagement structure, so that the lifting assembly 30 drives the guide vehicle 20 to perform linear lifting and lowering motion through the lifting arm 301.

[0051] It should be noted that the first direction proposed in this embodiment is the X-axis direction or the length direction of the frame 10, and the axial direction proposed in this embodiment is the Z-axis direction or the height direction of the frame 10. Furthermore, the maintenance station proposed in this embodiment is located at the center of the bottom of the frame 10. When the guide trolley 20 enters the maintenance station with its width direction parallel to the first direction, the width advantage of the trolley ensures that the two sides of the guide trolley 20 maintain an equidistant safe clearance from the frame 10. At this time, the two sides of the guide trolley 20 along its width direction correspond to the lifting arm 301. When the guide trolley 20 rotates 90° in place, its length direction becomes parallel to the first direction, meaning that the two sides of the guide trolley 20 along its length direction correspond to the lifting arm 301. After the guide trolley 20 rotates 90° in place, the length of the side of the guide trolley 20 facing the lifting arm 301 increases, thereby allowing the lifting arm 301 to insert into the guide trolley 20 and form a rigid connection structure.

[0052] In this embodiment, the guide vehicle maintenance platform also includes a main control unit (not shown, the same throughout), which is electrically connected to the lifting assembly 30.

[0053] Thus, once the guide vehicle 20 correctly enters the maintenance bay (e.g.) Figure 1 As shown), the control unit controls the lifting assembly 30 to lower the lifting arm 301 to the designated position of the guide vehicle 20. Then, the operator controls the guide vehicle 20 to rotate 90° in the opposite direction in place via an external control device, so that the lifting arm 301 is inserted into the guide vehicle 20 and forms a rigid engagement structure (as shown). Figure 4 (As shown), then the lifting assembly 30 drives the guide vehicle 20 to move upward in a straight line via the lifting arm 301, thus rising to a certain height (as shown). Figure 6 (As shown), and then the staff will perform maintenance on the bottom of the guide vehicle 20.

[0054] After maintenance is completed, the control unit will control the lifting assembly 30 to lower the lifting arm 301 and the guide vehicle 20 to the maintenance position. Then, the staff will control the guide vehicle 20 to rotate 90° in the opposite direction in place through the external control equipment, so that the lifting arm 301 will disengage from the guide vehicle 20. Then the guide vehicle 20 will drive out of the maintenance position, thus completing the maintenance work.

[0055] Therefore, compared to the existing technology where the maintenance platform requires top-mounted maintenance to first fix the AGV with clamps, then raise it to a certain height, place it on a platform for secondary fixation, and then maintain the bottom of the AGV, this utility model achieves top-mounted maintenance of the AGV by forming a rigid connection structure between the rotation of the guide vehicle 20 and the lifting arm 301, and by driving the guide vehicle 20 to make linear lifting motion through the lifting component 30. This simplifies the structure of the guide vehicle maintenance platform for top-mounted maintenance and reduces the production and maintenance costs of the guide vehicle maintenance platform.

[0056] Furthermore, when different models of the guide vehicles 20 drive into the maintenance bay, resulting in differences in the height of the guide vehicles 20, the staff can adjust the lowering height of the lifting arm 301 of the lifting assembly 30 to accommodate guide vehicles 20 of different heights.

[0057] In some embodiments, to ensure that the guide vehicle 20 rotates 90° so that the lifting arm 301 inserts into the guide vehicle 20 and forms a rigid engagement structure, such as... Figure 5 As shown, this embodiment proposes a rigid joint structure:

[0058] The top of the guide vehicle 20 is provided with a tray 201, and a first insertion space 202 adapted to the lifting arm 301 is formed between the tray 201 and the top of the guide vehicle 20.

[0059] The lifting assembly 30 drives the lifting arm 301 to descend to the designated position of the guide vehicle 20, and the pallet 201 rotates around the vertical axis of the frame 10, so that the lifting arm 301 matches and inserts into the corresponding first insertion space 202.

[0060] In this way, when the guide vehicle 20 correctly enters the maintenance station, the control unit will control the lifting assembly 30 to drive the lifting arm 301 to descend to the height of the first insertion space 202 of the guide vehicle 20, so that the insertion end of the lifting arm 301 is on the same horizontal line as the first insertion space 202. Then, the staff will control the guide vehicle 20 to rotate 90° in place through the external control equipment, so that the lifting arm 301 is inserted into the first insertion space 202 and forms a rigid joint structure. Then, the lifting assembly 30 will drive the guide vehicle 20 to move upward in a straight line through the lifting arm 301. After rising to a certain height, the staff will then perform maintenance on the bottom of the guide vehicle 20.

[0061] In other embodiments, to ensure that the guide vehicle 20 rotates 90° so that the lifting arm 301 inserts into the guide vehicle 20 and forms a rigid engagement structure, such as... Figure 4 As shown, this embodiment proposes another rigid joint structure:

[0062] The top of the guide vehicle 20 is provided with a tray 201, and the tray 201 is provided with a second insertion space 203 that is adapted to the lifting arm 301;

[0063] The lifting assembly 30 drives the lifting arm 301 to descend to the designated position of the guide vehicle 20, and the pallet 201 rotates around the vertical axis of the frame 10, so that the lifting arm 301 is matched and inserted into the corresponding second insertion space 203.

[0064] It should be noted that the tray 201 proposed in this embodiment is preferably a double-layer structure, in which a second insertion space 203 is formed.

[0065] In this way, when the guide vehicle 20 correctly enters the maintenance station, the control unit will control the lifting assembly 30 to drive the lifting arm 301 to descend to the height of the second insertion space 203 of the guide vehicle 20, so that the insertion end of the lifting arm 301 is on the same horizontal line as the second insertion space 203. Then, the staff will control the guide vehicle 20 to rotate 90° in place through the external control equipment, so that the lifting arm 301 is inserted into the second insertion space 203 and forms a rigid joint structure. Then, the lifting assembly 30 will drive the guide vehicle 20 to move upward in a straight line through the lifting arm 301. After rising to a certain height, the staff will then perform maintenance on the bottom of the guide vehicle 20.

[0066] Of course, in other embodiments (not shown in the figure), the support plate 201 on the top of the guide vehicle 20 can be set as a rotating structure. In this case, the guide vehicle 20 itself does not rotate, but only the support plate 201 rotates. This also enables the lifting arm 301 to be inserted into the first insertion space 202 or the second insertion space 203 and form a rigid joint structure. Then the lifting assembly 30 drives the guide vehicle 20 to move upward in a straight line through the lifting arm 301. After rising to a certain height, the staff can then maintain the bottom of the guide vehicle 20.

[0067] In some embodiments, such as Figures 1-2 As shown, the guide vehicle maintenance platform also includes a synchronization component 40;

[0068] A synchronization component 40 is provided between the tops of the lifting components 30 located on both sides of the maintenance station along the first direction. The synchronization component 40 is used to drive all the lifting components 30 to lift synchronously.

[0069] In this embodiment, the synchronization component 40 drives all lifting components 30 to lift and lower synchronously, so that the guide vehicle 20 remains horizontal during the lifting process and will not tilt due to asynchronous lifting of the lifting components 30, which could cause the guide vehicle 20 to fall and be damaged.

[0070] In other embodiments, to further ensure the stability of the lifting arm 301 inserted into the first insertion space 202 or the second insertion space 203 of the guide vehicle 20, this embodiment proposes to set the lifting arm 301 as an electromagnet structure. The inner wall of the first insertion space 202 or the second insertion space 203 is made of magnetically conductive materials such as low-carbon steel (e.g., Q235), silicon steel, or nickel alloy to ensure efficient penetration of magnetic lines of force and the formation of a closed loop. Thus, when the lifting arm 301 is inserted into the first insertion space 202 or the second insertion space 203 of the guide vehicle 20, the main control unit energizes the lifting arm 301 to generate a strong magnetic field. This magnetic field creates a magnetic attraction between the lifting arm 301 and the inner wall of the first insertion space 202 or the second insertion space 203, significantly increasing the friction of the contact surface and preventing the lifting arm 301 from accidentally dislodging under vibration or impact. When disconnection is required, the lifting arm 301 is de-energized and demagnetized, and the lifting arm 301 quickly separates from the first insertion space 202 or the second insertion space 203 to avoid mechanical jamming.

[0071] In other embodiments, the guided vehicle maintenance platform can also be configured to operate automatically and intelligently, specifically:

[0072] The frame 10 is equipped with a high-precision displacement sensor corresponding to the maintenance station. After the high-precision displacement sensor detects whether the guide trolley 20 has correctly entered the maintenance station, it will send a prompt electrical signal to the main control unit. Upon receiving the signal, the main control unit will control the lifting arm 301 of the lifting assembly 30 to descend to the first insertion space 202 or the second insertion space 203. Then, the main control unit will send a rotation electrical signal to the guide trolley 20. Upon receiving the signal, the guide trolley 20 will rotate 90° in place so that the lifting arm 301 is inserted into the first insertion space 202 or the second insertion space 203 to form a rigid connection structure. Then, the lifting assembly 30 will drive the guide trolley 20 to move upward in a straight line through the lifting arm 301. After rising to a certain height, the staff will then perform maintenance on the bottom of the guide trolley 20.

[0073] After maintenance is completed and the staff leaves the activity range of the guide vehicle maintenance platform, the control unit will control the lifting assembly 30 to drive the lifting arm 301 to descend, so that the guide vehicle 20 descends to the maintenance position. Then the control unit sends a reverse rotation electrical signal to the guide vehicle 20. After receiving the signal, the guide vehicle 20 will rotate 90° in the opposite direction in place, so that the lifting arm 301 disengages from the first insertion space 202 or the second insertion space 203. Then the guide vehicle 20 drives out of the maintenance position.

[0074] In some embodiments, to ensure that the lifting assembly 30 can stably drive the guide vehicle 20 to rise and fall, such as Figures 1 to 2 As shown, this embodiment proposes a structural composition of the lifting assembly 30:

[0075] The lifting assembly 30 also includes a lifting guide rail 302, a lead screw 303, and a drive assembly 304;

[0076] The frame 10 is provided with lifting guide rails 302 and lead screws 303 on both sides of the first direction along the axial direction and in parallel. The lead screws 303 are rotatably mounted on the frame 10. At least one end of the lead screws 303 is connected to a drive assembly 304.

[0077] A lifting arm 301 is slidably connected to the lifting guide rail 302. The lifting arm 301 is provided with a matching ball nut (not shown, same throughout the text) corresponding to the lead screw 303. The ball nut is threadedly engaged with the lead screw 303.

[0078] When the drive assembly 304 drives the lead screw 303 to rotate, the ball nut moves axially along the lead screw 303 and drives the lifting arm 301 to move linearly up and down along the lifting guide rail 302.

[0079] It should be noted that the drive component 304 proposed in this embodiment is preferably a motor.

[0080] The lifting guide rail 302 is fixed to the frame 10 at both its top and bottom ends along the axial direction via a first base 305. An angular contact bearing is installed inside the first base 305, forming a rotatable connection with a corresponding lead screw 303. The top end of the lead screw 303 extends through and out of the corresponding first base 305. The height of the lead screw 303 is higher than or equal to the height of the lifting guide rail 302, and the outer surface of the lead screw 303 has a continuous thread structure.

[0081] After the guide vehicle 20 correctly enters the maintenance station, the control unit controls the drive assembly 304 to drive the lead screw 303 to rotate forward. The ball nut descends along the lead screw 303, and the ball nut drives the lifting arm 301 to descend linearly along the lifting guide rail 302 to the height of the first insertion space 202 or the second insertion space 203 of the guide vehicle 20, so that the insertion end of the lifting arm 301 is on the same horizontal line as the first insertion space 202 or the second insertion space 203. Then, the staff controls the guide vehicle 20 to rotate 90° in place through the external control equipment, so that the lifting arm 301 is inserted into the first insertion space 202 or the second insertion space 203 and forms a rigid engagement structure. Then, the control unit controls the drive assembly 304 to drive the lead screw 303 to rotate in the opposite direction, and the ball nut rises along the lead screw 303. The ball nut drives the lifting arm 301 and the guide vehicle 20 to rise linearly along the lifting guide rail 302. After rising to a certain height, the staff then performs maintenance on the bottom of the guide vehicle 20.

[0082] In some embodiments, to ensure that the synchronization component 40 can stably drive all lifting components 30 to move up and down synchronously, such as Figure 2 As shown, this embodiment proposes a structural composition of the synchronization component 40:

[0083] The synchronization component 40 includes a synchronization pulley 401 and a synchronization belt 402;

[0084] All of the lead screws 303 are equipped with a timing pulley 401 at their top ends, and a timing belt 402 is provided around the outer surface of all the timing pulleys 401.

[0085] It should be noted that a synchronous pulley 401 is connected to the top end of the lead screw 303 extending from the first base 305. This embodiment uses a lead screw 303 connected to a drive assembly 304 as an example, wherein the synchronous pulley 401 on the lead screw 303 connected to the drive assembly 304 is the driving pulley, and the synchronous pulley 401 on the lead screw 303 not connected to the drive assembly 304 is the driven pulley.

[0086] In this way, when the drive assembly 304 drives the corresponding lead screw 303 to rotate, the lead screw 303 drives the synchronous belt 402 to rotate cyclically through the drive wheel, and then the synchronous belt 402 drives another lead screw 303 to rotate synchronously through the driven wheel, so that all the lifting arms 301 rise and fall synchronously.

[0087] In some embodiments, such as Figure 1 As shown, the frame 10 is equipped with a tension adjustment component 50 corresponding to the timing belt 402, and the tension adjustment component 50 is used to adjust the tension of the timing belt 402.

[0088] Specifically, such as Figure 3 As shown, the tension adjustment assembly 50 includes a second base 501 and a tensioning wheel 502; wherein, the frame 10 is slidably connected to the upper part of the synchronous belt 402 with the second base 501, and the second base 501 is provided with the tensioning wheel 502 corresponding to the synchronous belt 402. The tensioning wheel 502 is matched and installed on the slack side of the synchronous belt 402 drive (i.e., the side of the synchronous belt 402 away from the drive pulley).

[0089] When it is necessary to adjust the tension of the timing belt 402, it can slide to the designated position through the second base 501 and then be fixed to prevent the second base 501 from slipping away from the designated position, thereby changing the radial pressure of the tensioning wheel 502 on the timing belt 402. By using mechanical adjustment or elastic compensation, a constant tension is maintained to ensure the transmission efficiency and life of the timing belt 402.

[0090] In some embodiments, the frame 10 is hollowed out on both sides along a second direction, which is perpendicular to the first direction.

[0091] It should be noted that the second direction in this embodiment is preferably the Y-axis direction or the width direction of the frame 10.

[0092] In this way, the guide vehicle 20 can enter the maintenance station through the frame 10 which is hollowed out on both sides along the second direction, and the hollowed-out frame 10 can further reduce the production cost of the guide vehicle maintenance platform.

[0093] In some embodiments, such as Figure 1 As shown, the guide vehicle maintenance platform also includes a warning component 60, which is used to issue an alarm when the guide vehicle maintenance platform malfunctions.

[0094] It should be noted that the warning component 60 proposed in this embodiment is located on the top of the frame 10, the warning component 60 is electrically connected to the main control unit, and the warning component 60 is preferably a warning light.

[0095] This system will issue an alarm when the maintenance platform of the guide vehicle malfunctions, allowing staff to promptly inspect and maintain it. Malfunctions include, but are not limited to, drive component 304 failure, short circuit, overload, or poor contact, among other electrical faults.

[0096] In some embodiments, such as Figure 7 As shown, the guide vehicle maintenance platform also includes a switch button 70 and an emergency stop button 80 that are electrically connected to the main control unit; wherein, the switch button 70 is used for the normal start, stop or mode switching (such as running / standby state conversion) of the guide vehicle maintenance platform; the emergency stop button 80 is used to immediately cut off the power supply of the main control circuit and forcibly stop all mechanical actions in the event of abnormality of the guide vehicle maintenance platform or personal danger.
