Description
Technical Field
[0001] This invention relates to the field of intelligent warehousing and handling equipment and automated guided vehicles for warehousing, and more specifically, to an intelligent warehousing AGV synchronous belt drive walking buffer device. Background Technology
[0002] With the development of intelligent warehousing systems, automated guided vehicles (AGVs) are widely used for cargo transfer between rack areas, storage aisles, conveyor lines and loading and unloading stations. Existing automated guided vehicles usually have drive wheels on both sides of the frame, and power is transmitted to the drive wheels through drive motors, synchronous pulleys and synchronous belts to meet the operational needs of low-speed start and stop, frequent reversal and fixed-point handling.
[0003] Existing automated guided vehicles (AGVs) often employ fixed spring stiffness and fixed preload in their walking buffer structures, making it difficult to meet the different support requirements under unloaded, medium-loaded, and heavy-load conditions. When the preload is low, under heavy load conditions, the vehicle body may sink excessively, the effective buffer stroke of the spring may be insufficient, and the stability of the drive wheel support may decrease. When the preload is high, under unload conditions, the buffer mechanism may be too stiff, and the drive wheel may not be able to follow small ground undulations effectively. If the spring preload is changed synchronously by the continuous displacement of the load-bearing platform, the adjustment components may frequently operate due to cargo swaying and driving bumps, causing the buffer state to fluctuate continuously. Summary of the Invention
[0004] To overcome the above deficiencies, the present invention provides an intelligent warehouse AGV synchronous belt driven walking buffer device that overcomes or at least partially solves the above technical problems.
[0005] This invention is implemented as follows: This invention provides a synchronous belt-driven walking buffer device for intelligent warehousing AGVs, including an AGV frame, a load-bearing top plate fixed to the top of the AGV frame, and a warehousing AGV walking buffer mechanism mounted on the AGV frame. The warehousing AGV walking buffer mechanism includes... The guide rail is fixed vertically on both sides of the AGV frame. A first slide block is slidably provided on the surface of the guide rail.

The upper end of the guide rod is fixedly connected to the bearing platform, and a second spring is provided between the bearing top plate and the bearing platform.
[0008] In a preferred embodiment, the top plate of the support is provided with a receiving cavity, and a dividing adjustment plate is slidably arranged in the vertical direction inside the receiving cavity. The bottom of the dividing adjustment plate extends through to the bottom of the top plate of the support. A linkage beam is fixed between several second slides, and the bottom of the dividing adjustment plate is fixedly connected to the linkage beam.
[0009] In a preferred embodiment, a limiting rod extending vertically is fixed inside the receiving cavity, an ear plate is fixed on the dividing adjustment plate, the ear plate is slidably sleeved on the surface of the limiting rod, and a third spring is provided between the inner bottom wall of the receiving cavity and the ear plate.
[0010] In a preferred embodiment, a reset guide groove and several grade adjustment grooves are sequentially formed on one side of the grade adjustment plate along the vertical direction. Both the reset guide groove and the grade adjustment groove include an inclined guide surface. The inclined guide surfaces of the several grade adjustment grooves have progressively increasing vertical lengths along the moving direction of the grade adjustment plate. The vertical projection length of the inclined guide surface of the reset guide groove is not less than the vertical projection length of the inclined guide surface of any grade adjustment groove.
[0011] In a preferred embodiment, each of the grade adjustment slots has a retaining groove at its end, and the number of retaining grooves is the same as the number of grade adjustment slots.
[0012] In a preferred embodiment, a second telescopic rod is fixed to the inner wall of the receiving cavity, a connecting strip is fixed to the second telescopic rod, a bracket is fixed to the other side of the connecting strip, and a fourth spring is provided between the connecting strip and the inner wall of the receiving cavity.
[0013] In a preferred embodiment, a passive drive block is fixed on the side of the connecting strip away from the card holder, and both the upper and lower sides of the passive drive block are set as inclined surfaces.
[0014] In a preferred embodiment, a drive rod is fixed to the bottom of the support platform, and an active drive block is fixed to the bottom of the drive rod. The upper and lower sides of the active drive block are both set as inclined surfaces.
[0015] The present invention provides a synchronous belt driven walking buffer device for intelligent warehouse AGV, the beneficial effects of which include: 1. By setting up a walking buffer mechanism for the warehouse AGV, the walking wheels can float vertically along the guide rail with the floating frame. When the AGV passes through the warehouse floor joints, rail welds, or local protrusions, the walking buffer springs can absorb the vertical impact on the walking wheels and push the walking wheels downward to reset after passing the protrusion, thereby improving the AGV's ground contact, passing stability, and smooth cargo transportation.
[0016] 2. By setting up a buffer force adjustment mechanism, the continuous load change of the bearing platform is converted into three discrete preload states: light load, medium load, and heavy load. This allows the upper spring seat to automatically move to the corresponding position according to the load, so that the walking buffer spring has an appropriate initial compression under different load conditions, taking into account both the buffer sensitivity under light load and the support capacity under heavy load.
[0017] 3. By setting up a gear adjustment slot, a card slot, a card holder, and a reset guide slot, the upper spring seat can be stably maintained in the corresponding position when the load is within the range of the current gear, avoiding frequent changes in the pre-tension state due to cargo bumps; when the load exceeds the switching threshold of the adjacent gear, it can automatically switch gears and automatically reset to the light load gear after the cargo is unloaded, thereby improving the stability and automation of gear adjustment.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0022] Reference Figures 1-8This invention provides a technical solution: a smart warehousing AGV synchronous belt driven walking buffer device, including an AGV frame 1, a supporting top plate 2 fixed on the top of the AGV frame 1, and a warehousing AGV walking buffer mechanism provided on the AGV frame 1. The warehousing AGV walking buffer mechanism includes guide rails 301 and supporting plates 305. The guide rails 301 are fixed vertically to both sides of the AGV frame 1 by bolts. In this embodiment, four sets of guide rails 301 are provided, each set including two parallel guide rails. 301. A first slide block 302 is slidably disposed on the surface of the guide rail 301. A floating frame 303 is fixed to the first slide block 302 by bolts. A traveling wheel 304 is rotatably disposed on the bottom of the floating frame 303 via a wheel axle. The traveling wheel 304 is rotatably disposed on the floating frame 303 via a wheel axle and rolling bearing. A receiving plate 305 is fixed to the first slide block 302 by bolts or welding. A traveling buffer spring 306 is disposed on the top of the receiving plate 305 via a lower spring seat. The surface of the guide rail 301... A second slide block 307 is slidably positioned above the first slide block 302. A pressure plate 308 is welded and fixed to the second slide block 307. The other end of the travel buffer spring 306 is connected to the pressure plate 308 via an upper spring seat. The upper and lower spring seats are used to limit the horizontal displacement of the travel buffer spring 306. By setting up a travel buffer mechanism for the warehouse AGV, when the automated guided vehicle (AGV) travels in the warehouse aisle and passes through floor joints, track welds, transition plates, or local protrusions, the travel buffer mechanism is activated. The wheel 304 is subjected to the force of the ground and drives the floating frame 303, the first slide 302, the support plate 305 and the lower spring seat to move vertically upward along the guide rail 301, so that the walking buffer spring 306 is compressed between the lower spring seat and the upper spring seat, thereby absorbing the vertical impact on the wheel 304. After the wheel 304 passes over the protrusion, the walking buffer spring 306 releases its elastic potential energy, pushing the floating frame 303 and the wheel 304 to return to their original position downward, so that the wheel 304 continues to maintain contact with the storage floor. Reference Figures 1-8A mounting bracket 309 is bolted to the floating frame 303. A motor 310 is bolted to the mounting bracket 309 and mounted on it. A driving synchronous pulley is coaxially mounted on the output shaft of the motor 310 via a key connection or a shrink sleeve connection. A driven synchronous pulley is coaxially mounted on the axle of the traveling wheel 304. A toothed synchronous belt meshes between the driving and driven synchronous pulleys. The driving, driven, and toothed synchronous pulleys are all in the same transmission plane. The motor 310 is thus positioned within this transmission plane. The floating frame 303 floats vertically in sync with the floating frame, thus keeping the center distance between the active and driven synchronous pulleys constant during the floating process. This prevents the toothed synchronous belt from becoming overly tensioned, loose, or skipping teeth during the travel buffering process. When the motor 310 is working, the output shaft of the motor 310 drives the active synchronous pulley to rotate. The active synchronous pulley transmits power to the driven synchronous pulley through the toothed synchronous belt. The driven synchronous pulley drives the traveling wheel 304 to rotate through the wheel axle, thereby driving the automated guided vehicle (AGV) to travel in the warehouse aisle. Reference Figures 1-8 The AGV frame 1 is equipped with a buffer force adjustment mechanism, which includes a bearing platform 401. The bearing platform 401 is located above the bearing top plate 2. The AGV frame 1 is equipped with several sets of bearing guide components 402. The bearing guide component 402 includes a guide sleeve fixed on the bearing top plate 2 and a guide rod slidably passing through the guide sleeve. The upper end of the guide rod is fixedly connected to the bearing platform 401. A second spring 403 is provided between the bearing top plate 2 and the bearing platform 401. By setting up the buffer force adjustment mechanism, the bearing platform 401 can generate a detection displacement within a limited range vertically downward along the bearing guide component 402 under the action of cargo load. The second spring 403 is used to support the bearing platform 401 and push the bearing platform 401 upward to reset after the cargo is unloaded. The downward displacement of the bearing platform 401 increases with the increase of the load and serves as the mechanical input of the subsequent gear adjustment mechanism, so that the initial compression of the walking buffer spring 306 can be adjusted in gears according to light load, medium load and heavy load conditions. Reference Figures 1-8The top plate 2 has a cavity 404 inside. A slidable adjustment plate 405 is installed vertically inside the cavity 404. The bottom of the slid adjustment plate 405 extends to the bottom of the top plate 2. A linkage beam 406 is fixed between several second slides 307. The bottom of the slid adjustment plate 405 is fixedly connected to the linkage beam 406 so that the slid adjustment plate 405 can drive several second slides 307 to move synchronously along the corresponding guide rail 301 through the linkage beam 406. By setting the linkage beam 406, the vertical displacement of the slid adjustment plate 405 can be synchronously transmitted to multiple second slides 307 on the left and right sides of the AGV frame 1, thereby causing multiple upper spring seats to change position synchronously. This avoids uneven force or skewed driving of the AGV frame 1 due to different initial compression of the left and right walking buffer springs 306. Reference Figures 1-8 A limiting rod 407 extending vertically is fixed inside the receiving cavity 404. An ear plate 408 is fixed on the dividing adjustment plate 405. The ear plate 408 is slidably sleeved on the surface of the limiting rod 407. A third spring 409 is provided between the inner bottom wall of the receiving cavity 404 and the ear plate 408. The third spring 409 is sleeved on the outside of the limiting rod 407 and is used to push the ear plate 408 and the dividing adjustment plate 405 to reset. Through the sliding cooperation between the limiting rod 407 and the ear plate 408, the dividing adjustment plate 405 is restricted to move only in the vertical direction, so as to avoid the dividing adjustment plate 405 from swaying or jamming when it is squeezed by the clamp 415. The third spring 409 is used to apply an upward reset force to the dividing adjustment plate 405. When the goods on the carrying platform 401 are removed and the locking state is released, the third spring 409 pushes the dividing adjustment plate 405, the linkage beam 406, the second slide 307 and the upper spring seat to gradually reset upward. Reference Figures 1-8 One side of the gear adjustment plate 405 is provided with a reset guide groove 410 and several gear adjustment grooves 411 in sequence along the vertical direction. Both the reset guide groove 410 and the gear adjustment grooves 411 include inclined guide surfaces. The inclined guide surfaces of the several gear adjustment grooves 411 have progressively increasing vertical lengths along the moving direction of the gear adjustment plate 405. The vertical projection length of the inclined guide surface of the reset guide groove 410 is not less than the vertical projection length of the inclined guide surface of any gear adjustment groove 411. By setting gear adjustment grooves 411 with different vertical projection lengths, when the card holder 415 moves along the inclined guide surfaces of different gear adjustment grooves 411, it can push the gear adjustment plate 405 to produce different vertical displacements. When the gear adjustment plate 405 moves down, it drives several second slides 307 and the upper spring seat to move down synchronously through the linkage beam 406, so that the initial compression of the walking buffer spring 306 increases sequentially, forming different pre-tightening states corresponding to light load gear, medium load gear and heavy load gear respectively. Reference Figures 1-8Each gear adjustment slot 411 has a locking slot 412 at its end. The number of locking slots 412 is the same as the number of gear adjustment slots 411. The locking slot 412 has a horizontal positioning surface, which is used to restrict the movement of the gear adjustment plate 405 in the vertical direction after the locking frame 415 enters the locking slot 412. By setting the locking slot 412, the locking frame 415 forms a mechanical lock on the gear adjustment plate 405 after entering the locking slot 412 of the corresponding gear. When the load of the carrying platform 401 is within the load range corresponding to the current gear, even if there is a small vibration or slight bumping of the goods during AGV transportation, the locking frame 415 remains in the locking slot 412, so that the position of the upper spring seat and the preload of the walking buffer spring 306 remain unchanged. Reference Figures 1-8 A second telescopic rod 413 is fixed to the inner wall of the receiving cavity 404. A connecting strip 414 is fixed to the second telescopic rod 413. A bracket 415 is fixed to the other side of the connecting strip 414. A fourth spring 416 is provided between the connecting strip 414 and the inner wall of the receiving cavity 404. The fourth spring 416 is used to push the connecting strip 414 and the bracket 415 toward the dividing adjustment plate 405. A passive drive block 417 is fixed to the side of the connecting strip 414 away from the bracket 415. The upper and lower sides of the passive drive block 417 are both set as inclined surfaces. Several passive drive blocks 417 are arranged sequentially along the downward direction of the bearing platform 401. The passive drive block 417 and the connecting bar 414 are arranged in a staggered manner, corresponding to light load, medium load and heavy load gear respectively. The distance between the bottom of the passive drive block 417 and the bottom of the connecting bar 414 is greater than the depth of the slot 412. By arranging the passive drive blocks 417 in sequence along the vertical direction, when the bearing platform 401 drives the active drive block 419 to move downward, the active drive block 419 can contact the passive drive block 417 corresponding to different gears in sequence. After the passive drive block 417 is squeezed, it drives the connecting bar 414 and the card holder 415 to move along the horizontal guide rod, so that the current card holder 415 exits the slot 412, providing the unlocking condition for the gear adjustment plate 405 to enter the next gear. Reference Figures 1-8A drive rod 418 is fixedly mounted on the bottom of the support platform 401, and an active drive block 419 is fixedly mounted on the bottom of the drive rod 418. The upper and lower sides of the active drive block 419 are both inclined surfaces. The active drive block 419 and several passive drive blocks 417 are in the same vertical motion plane, and the active drive block 419 can sequentially abut against several passive drive blocks 417 as the support platform 401 moves up and down. By providing a slot 412, the position of the gear adjustment plate 405 is maintained until the next gear is reached. When the support platform 401 moves downward, it drives the drive rod 418 and the active drive block 419 downward. With the cooperation of the inclined surfaces of the active drive block 419 and the passive drive block 417, the uppermost passive drive block 417 first causes the connecting bar 414 and the card holder 415 to move towards the reset guide groove 410. After the travel buffer spring 306 is compressed once, the active drive block 419 disengages from the uppermost passive drive block 417 and squeezes the second passive drive block 417, causing the card holder 415 to engage the gears. The inclined surface of the adjusting groove 411 is pressed, causing the shifting adjusting plate 405 to move until the horizontal end of the bracket 415 is engaged in the inside of the slot 412, at which point it is in the first position. If the transported goods are heavy, the carrying platform 401 exceeds the threshold of the second position, and the active drive block 419 contacts the second passive drive block 417. Since the length of the inclined surface of the shifting adjusting groove 411 increases sequentially, the shifting adjusting plate 405 moves down a greater distance at this time. During this process, the bracket 415 in the upper first position is under the influence of the fourth spring 416. Under the action of the rebound force, it disengages from the inside of the slot 412 until the second gear slot 415 is engaged in the corresponding slot 412, and so on, thereby improving the stability of the preload of the walking buffer spring 306. When the transported goods are unloaded, the active drive block 419 returns to its original position and the active drive block 419 presses the uppermost passive drive block 417. Since the length of the inclined surface of the reset guide groove 410 is not less than the length of the inclined surface of the lowermost gear adjustment groove 411, the horizontal end of the slot 415 disengages from the inside of the slot 412.
[0023] Specifically, the working process or working principle of this intelligent warehousing AGV synchronous belt driven walking buffer device is as follows: During use, the goods to be transported are placed and fixed on the carrying platform 401. Under the load of the goods, the carrying platform 401 moves vertically downwards along the carrying guide assembly 402. The guide rod slides along the guide sleeve to limit the carrying platform 401 to only generate detection displacement in the vertical direction. The second spring 403 is compressed as the carrying platform 401 moves downwards. The downward displacement of the carrying platform 401 increases with the increase of the load of the goods, and the drive rod 418 drives the active drive block 419 synchronously to move downwards. When the load-bearing platform 401 is in an unloaded state, the shift adjustment plate 405 holds multiple second sliding seats 307 in a higher position through the linkage crossbeam 406. The distance between the upper and lower spring seats is relatively large, and the travel buffer spring 306 has a small initial compression, giving the floating frame 303 and the traveling wheels 304 a more sensitive vertical floating capability to adapt to the working conditions where the vehicle body mass is small and the traveling wheels 304 are prone to jumping under unload conditions. When the cargo load on the load-bearing platform 401 increases and reaches the first switching threshold, the load-bearing platform 401 drives the drive rod 418 and the active drive. As block 419 moves downward, the lower inclined surface of the active drive block 419 abuts against the passive drive block 417 corresponding to the light load position. As the active drive block 419 continues to move downward, the passive drive block 417 experiences a lateral force, causing the connecting bar 414 and the bracket 415 to overcome the elastic force of the fourth spring 416 and move along the second telescopic rod 413 towards the gear adjustment plate 405, thus inserting the bracket 415 corresponding to the light load position into the slot 412. When the cargo meets the second switching threshold, the active drive block 419 acts on the passive drive block 417 corresponding to the medium load position, and the bracket 415 corresponding to the medium load position... 15 abuts against the inclined guide surface of the corresponding gear adjustment groove 411. Under the combined action of the active drive block 419, the passive drive block 417 and the connecting bar 414, the card holder 415 moves along the inclined guide surface of the gear adjustment groove 411 and applies a downward component force to the gear adjustment plate 405, so that the gear adjustment plate 405 overcomes the reset force of the third spring 409 and moves downward along the limit rod 407. The gear adjustment plate 405 drives several second slides 307, pressure plates 308 and upper spring seats to move downward synchronously through the linkage beam 406, so that the initial compression of the travel buffer spring 306 increases.
[0024] When the AGV moves, the motor 310 is started. The output shaft of the motor 310 drives the active synchronous pulley to rotate. The active synchronous pulley drives the driven synchronous pulley to rotate through the toothed synchronous belt. The driven synchronous pulley drives the traveling wheel 304 to rotate through the wheel axle, thereby driving the AGV to move in the warehouse aisle. Since the motor 310, the active synchronous pulley, the driven synchronous pulley, and the traveling wheel 304 are all mounted on the floating frame 303, the above components can move vertically along the guide rail 301 with the floating frame 303 as a whole. This keeps the center distance between the active and driven synchronous pulleys basically constant during the floating process, preventing the toothed synchronous belt from becoming loose, over-tensioned, or skipping teeth. When the traveling wheel 304 passes through the warehouse floor joint, track weld, transition plate, or local protrusion, the traveling wheel 304 is subjected to an upward force from the ground, which drives the wheel axle, the floating frame 303, the first slide 302, the support plate 305, and the lower spring seat to move vertically upward along the guide rail 301. Since the upper spring seat is locked by the gear adjustment plate 405 and the bracket 415 in the current load position, the lower spring seat moves upward, causing the walking buffer spring 306 to be further compressed. The walking buffer spring 306 absorbs the vertical impact on the walking wheel 304. After the walking wheel 304 passes the protrusion, the walking buffer spring 306 releases its elastic potential energy, pushing the lower spring seat, the support plate 305, the first slide 302, the floating frame 303 and the walking wheel 304 to reset downward, so that the walking wheel 304 re-stabilizes and adheres to the storage ground. When the goods are transported and unloaded from the carrying platform 401, the second spring 403 releases its elastic potential energy and pushes the carrying platform 401 to reset vertically upward along the carrying guide assembly 402. The carrying platform 401 drives the active drive block 419 to move upward synchronously through the drive rod 418. During the upward movement, the active drive block 419 releases the locked state of the current gear by pressing its upper inclined surface against the passive drive block 417 corresponding to the uppermost reset guide groove 410.
