Description

Technical Field

[0001] The present invention relates to the technical field of forklifts, and in particular to a battery pack transporting forklift. Background Art

[0002] Forklift AGV is a transport vehicle equipped with an automatic guided device, capable of traveling along a prescribed guide path, with safety protection and various transplanting functions. It does not require a driver and is equipped with an electromagnetic or optical guidance device. It can travel along a prescribed guide path and has a trolley running and parking device, a safety protection device, and a transport forklift with a transfer function. Due to its advantages such as speed and convenience, it is widely used in workshops, warehouses, airports, logistics and other places. It is an important branch of intelligent manufacturing and is increasingly used in Industry 4.0 scenarios.

[0003] In the prior art, a fork collision protection device for an AGV forklift with publication number CN118270695A is disclosed. The fixed plate drives the clamping plate connected thereto to move relatively inward synchronously, so that two sets of relative clamping plates perform a clamping operation. The two sets of relative clamping plates clamp and limit the cargo, thereby ensuring the stability of the cargo when it is impacted and preventing the cargo from falling due to impact.

[0004] Although it can protect both sides of the goods on the forklift, there are still some defects in actual use. Since the transport forklift can only protect the two sides of the fork, it cannot protect the front side of the fork. Therefore, when the forklift transports some batteries or precision electronic devices, the safety performance of the transported goods cannot be guaranteed. In addition, most of the existing forklifts use AGV automatic guidance devices, which can travel along a specified guidance path. Once foreign objects appear on the specified route, the goods may be easily damaged by collision during transportation, which will affect the subsequent handling work and cause waste of goods.

[0021] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] like Figure 1-13 A battery pack handling forklift shown in the figure includes a fork AGV forklift 1 and a forklift platform 2 arranged on the lifting door frame of the AGV forklift 1. The forklift platform 2 is installed with a tilt sensor 34. The lifting door frame on the AGV forklift 1 can drive the forklift platform 2 to move up and down freely, and the AGV forklift 1 is provided with a monitoring module, a positioning module and an alarm module. The positioning module is used to accurately locate the position of the forklift battery insertion. The alarm module is used to alarm when the forklift is too close to the truck to be replaced or the surrounding obstacles are too close. The camera of the monitoring module automatically centers and levels the battery pack on the forklift platform to ensure the automatic handling of the battery pack and realize the automatic control of the AGV forklift 1. It is a mature technology in the prior art and will not be described in detail here. The forklift platform 2 is provided with a pushing mechanism 3 for pushing out the battery pack. The pushing mechanism 3 can push the goods on the forklift platform 2 , which is convenient for automatic unloading of the forklift platform 2. It is a mature technology in the prior art and will not be described in detail here. Both sides of the top of the forklift platform 2 are fixedly connected with a push rod 4, and the top of the push rod 4 is fixedly connected with an infrared laser transmitter 5 for ensuring the automatic driving of the AGV forklift 1. Through the setting of the infrared laser transmitter 5, when the AGV forklift 1 is carrying the battery pack, a laser can be emitted to the body of the truck to be replaced to ensure that the forklift moves in the direction of the laser beam and drives towards the forklift to achieve the initial positioning and ensure that the forklift finally stops at the battery pack position of the truck. At the same time, it can play a safety protection role during the driving of the AGV forklift 1. It is a mature technology in the prior art and will not be described in detail here. Side guard mechanisms for protecting both sides of the battery pack on the forklift platform 2 are provided next to the push rod 4, and a fixed frame 7 is provided at the bottom of the forklift platform 2. A front guard mechanism for protecting the front side of the battery pack on the forklift platform 2 is provided on the fixed frame 7; The front guard mechanism includes an upper electric telescopic cylinder 9, a pair of which are provided, and the upper electric telescopic cylinders 9 are fixedly connected to the bottom side of the forklift platform 2, and an L-shaped guard plate 10 is rotatably connected to the inner side of the fixed frame 7 and away from the side of the upper electric telescopic cylinder 9. It should be noted here that the hinge point between the L-shaped guard plate 10 and the fixed frame 7 is set at the top of the vertical end of the L-shaped guard plate 10, which can avoid the occurrence of a dead point when the pull rope 13 pulls the L-shaped guard plate 10 to flip, and a pull plate 11 is fixedly connected to the top of the L-shaped guard plate 10 and away from the side of the upper electric telescopic cylinder 9, a driving block 12 is slidably connected to the inner side of the fixed frame 7, and a pull rope 13 is fixedly connected between the driving block 12 and the pull plate 11, and an upper guide roller 14 is rotatably connected to the fixed frame 7. Through the setting of the upper guide roller 14, the sliding of the pull rope 13 can be guided. , and then when the driving block 12 pulls the draw rope 13, under the guidance of the upper guide roller 14, the draw rope 13 will be pulled to drag the L-shaped guard plate 10 to flip, and the draw rope 13 passes through the top of the upper guide roller 14, and the output end of the upper electric telescopic cylinder 9 passes through the side wall of the forklift platform 2 and is fixedly connected to the side wall of the driving block 12, and side grooves 15 are provided on both sides of the inner wall of the fixed frame 7, and side blocks 16 are fixedly connected on both sides of the driving block 12, and the side blocks 16 are slidably connected to the inner side of the side groove 15, and an upper spring 17 is fixedly connected between the inner side of the side groove 15 and the side wall of the side block 16. Through the setting of the upper spring 17, the driving block 12 can be pushed to reset, and at the same time, the thrust of the driving block 12 can be increased. When the fixed frame 7 is not restricted, the fixed frame 7 can be driven to slide under the forklift platform 2 through the movement of the driving block 12; When the AGV forklift 1 is carrying the battery pack, the AGV forklift 1 is first controlled to move to place the battery pack on the forklift platform 2, and then the AGV forklift 1 is controlled to move to an open position, and then the upper electric telescopic cylinder 9 is controlled to start pushing the drive block 12 to slide inside the fixed frame 7. Since the fixed frame 7 is not restricted at this time, and under the elastic force of the upper spring 17, the fixed frame 7 will be driven to slide under the forklift platform 2 through the movement of the drive block 12, and at the same time, the top block 8 will be driven to slide inside the top groove 6, and at the same time, the L-shaped guard plate 10 will be completely moved out from under the forklift platform 2. Then, when the L-shaped guard plate 10 is completely moved out from under the forklift platform 2, the top block 8 at this time will move to the end of the top groove 6, thereby restricting the top block 8 and the fixed frame 7 from continuing to slide; However, under the continued driving of the upper electric telescopic cylinder 9, the driving block 12 will be pushed to continue to move, thereby pushing the side blocks 16 on both sides of the driving block 12 to slide inside the side grooves 15 and gradually compressing the upper spring 17. At the same time, the movement of the driving block 12 will drive the pull rope 13 to move (originally, when the driving block 12 moves, it pushes the fixed frame 7 to slide at the same time, so it will not drive the pull rope 13 to move). Therefore, under the guidance of the upper guide roller 14, the pull rope 13 pulls the L-shaped guard plate 10 around the hinge with the fixed frame 7 to flip, thereby driving the L-shaped guard plate 10 to turn around the hinge with the fixed frame 7. The plate 10 is completely flipped 90 degrees and moved to the front side of the forklift platform 2, thereby protecting the front side of the battery pack, improving the safety performance of the AGV forklift 1 during the automatic cargo handling process, greatly improving the safety performance of the device, and finally controlling the AGV forklift 1 to start moving the battery pack to the specified position. Finally, after reaching the specified position, the upper electric telescopic cylinder 9 is controlled to start in reverse, thereby repeating the above operation in reverse to reset, and the L-shaped guard plate 10 is stored, and then the pushing mechanism 3 is controlled to start and push the battery pack on the forklift platform 2.

[0024] In order to improve the smoothness during the operation of the device, an inward groove 18 is opened at the bottom end of the forklift platform 2 away from the AGV forklift 1, and a lower guide roller 19 is rotatably connected to the inner side of the groove 18. Through the arrangement of the groove 18 and the lower guide roller 19, the pull rope 13 can be in contact with the lower guide roller 19 after the L-shaped guard plate 10 is turned over, thereby preventing the pull rope 13 from directly contacting the side wall of the forklift platform 2, and then when the L-shaped guard plate 10 is pulled to turn over, the pull rope 13 and the side wall of the forklift platform 2 are worn, thereby affecting the service life of the pull rope 13, while improving the smoothness of the pull rope 13 during the pulling process.

[0025] The L-shaped protective plate 10 is placed horizontally under the fixed frame 7, so that the folded L-shaped protective plate 10 is placed obliquely on the L-shaped limiting plate 20, thereby preventing the L-shaped protective plate 10 from being blocked by the top of the L-shaped limiting plate 20 when it is turned over by the pull rope 13, and improving the smoothness of the L-shaped protective plate 10 when it is turned over.

[0026] In order to limit the sliding of the fixed frame 7, a pair of top grooves 6 are opened at the bottom of the forklift platform 2, and a pair of top blocks 8 are fixedly connected to the top of the fixed frame 7, and the top block 8 is slidably connected to the inner side of the top groove 6. Through the arrangement of the top groove 6 and the top block 8, when the upper electric telescopic cylinder 9 pushes the driving block 12 and the fixed frame 7 to slide, the top block 8 can be driven to slide on the inner side of the top groove 6, thereby guiding and limiting the sliding of the fixed frame 7, preventing the fixed frame 7 from continuing to slide after moving into place, ensuring that the L-shaped guard plate 10 can be opened normally, and improving the stability of the device during operation.

[0027] In order to open the protection of both sides of the battery pack while opening the L-shaped guard plate 10, the side guard mechanism includes a side rod 21, a pair of side rods 21 are provided, the side rods 21 are slidably connected to both sides of the top of the forklift platform 2, a side guard cloth 22 is fixedly connected between the side rods 21 and the top rod 4, a sliding groove 23 is provided on the top of the forklift platform 2 and below the side rods 21, a round rod 24 is fixedly connected to the bottom of the side rods 21, an adjustment cavity 25 is provided inside the drive block 12, and sliding connections are penetrated on both sides of the drive block 12 There is a push rod 26 for pushing the round rod 24 to slide, and an adjustment mechanism for adjusting the position of the push rod 26 is provided in the adjustment chamber 25, and the round rod 24 is slidably connected to the inner side of the sliding groove 23. Through the arrangement of the sliding groove 23 and the round rod 24, the sliding of the side rod 21 can be guided. A lower spring 27 is fixedly connected between the inner side of the sliding groove 23 and the outer wall of the round rod 24. Through the arrangement of the lower spring 27, when the driving block 12 and the push rod 26 are reset, the round rod 24 is pushed to reset together with the push rod 26; During the operation of the front guard mechanism, the upper electric telescopic cylinder 9 is used to start the driving block 12 to move, thereby driving the push rods 26 on both sides of the driving block 12 to move at the same time, and then the round rod 24 is pushed to slide on the inner side of the sliding groove 23 by the push rod 26, and the lower spring 27 is gradually compressed, and the side guard cloth 22 is gradually opened until the L-shaped guard plate 10 is completely flipped open, and the side rod 21 is also moved to the corresponding position, and the side guard cloth 22 is fully opened to achieve protection on both sides of the battery pack on the forklift platform 2, further improving the protection effect of the device, and when the L-shaped guard plate 10 is retracted, the round rod 24 and the side rod 21 will be gradually pushed to reset under the elastic force of the lower spring 27, and the side guard cloth 22 will be squeezed and folded between the side rod 21 and the top rod 4.

[0028] In order to only open the front L-shaped guard plate 10 when carrying extra-long goods on the forklift platform 2, the adjustment mechanism includes a disc 28, which is rotatably connected to the middle of the inner side of the adjustment cavity 25. The upper and lower sides of the outer wall of the disc 28 are provided with recessed adjustment grooves 29, and the side close to the push rod 26 is fixedly connected with an extrusion rod 30. An adjustment spring 31 is fixedly connected between the inner side of the adjustment cavity 25 and the outer wall of the push rod 26. The setting of the adjustment spring 31 facilitates the extrusion rod 30 to slide into the adjustment groove 29, and the end of the extrusion rod 30 is tightly Closely fitting on the outer wall of the disc 28, the side wall of the driving block 12 is fixedly connected with a small servo motor 32, the output end of the small servo motor 32 passes through the inner side of the adjustment cavity 25 and is fixedly connected with the side wall of the disc 28, and the side walls of the side rods 21 are fixedly connected with infrared sensors 33 for detecting obstacles. The infrared sensors 33 can automatically detect whether the forklift platform 2 is carrying overlong goods, and then automatically control the small servo motor 32 to start, and control whether the side guard cloth 22 is opened together with the L-shaped guard plate 10, thereby improving the automation efficiency of the device; The side away from each other between the adjusting grooves 29 is tilted, so that the extrusion rod 30 can slide out of the inner side of the adjusting groove 29 more smoothly, thereby improving the smoothness of the device during operation. The end of the extrusion rod 30 is set as a smooth arc surface, so that the extrusion rod 30 can slide out of the adjusting groove 29 more smoothly, further improving the smoothness of the device during operation. The infrared sensor 33 is electrically connected to the small servo motor 32 through the controller. When the front guard mechanism is started, the infrared sensor 33 will monitor whether there are obstacles on the forklift platform 2 and the position where the side guard cloth 22 is to move. If the forklift platform 2 carries overlong goods, the infrared sensor 33 will detect it and transmit the signal to the controller. The controller controls the small servo motor 32 to start and drive the disc 28 to rotate, and then rotate the adjustment groove 29 to the side of the squeeze rod 30, thereby gradually releasing the squeeze on the squeeze rod 30, and then the squeeze rod 30 is pushed into the adjustment groove 29 under the elastic force of the adjustment spring 31, and the two push rods 26 are driven to The push rod 26 is moved away from the round rod 24, and the controller then controls the upper electric telescopic cylinder 9 of the front guard mechanism to start opening the L-shaped guard plate 10. At this time, since the push rod 26 is moved away from the round rod 24, the round rod 24 will not be driven to move to open the side guard cloth 22, thereby realizing the separate opening of the L-shaped guard plate 10 and improving the flexibility of the device. Finally, after the L-shaped guard plate 10 is reset, the controller controls the small servo motor 32 to reverse, thereby repeating the above operation in reverse to push out the extrusion rod 30 and the push rod 26.

[0029] In order to be able to adjust the tilt angle of the forklift platform 2 when an overweight battery pack is placed on the forklift platform 2, a tilt sensor 34 is fixedly connected to the forklift platform 2, and a U-shaped plate 36 is fixedly connected to the rear side of the forklift platform 2. The U-shaped plate 36 is rotatably connected to the inner side of the connecting frame 35. A pair of grooves 37 are opened on the side wall of the connecting frame 35. The inner sides of the grooves 37 are rotatably connected to the lower electric telescopic cylinders 38. The output ends of the lower electric telescopic cylinders 38 are hinged to the bottom ends of the side walls of the U-shaped plate 36.

[0030] Since the weight of the battery pack can usually reach 3 to 5 tons, when placing the forklift platform, it is easy to cause the front end to tilt downward, affecting the accuracy of installing the battery pack. The designed inclination sensor 34 can quickly measure the inclination angle of the forklift platform 2, and then transmit the inclination signal to the AGV forklift 1, and the lower electric telescopic cylinder 38 is electrically connected to the inclination sensor 34 through the controller. When the forklift platform 2 tilts, the AGV forklift 1 quickly controls the lower electric telescopic cylinder 38 to start, pushing the bottom of the U-shaped plate 36 to move, thereby pushing the U-shaped plate 36 to drive the forklift platform 2 to rotate around the hinge, and lifting the front end of the forklift platform 2 to a horizontal level, preventing the battery pack from sliding forward and squeezing the guide L-shaped guard plate 10, thereby ensuring the stability of the AGV forklift during use.

[0031] The basic principles, main features and advantages of the present invention are shown and described above.

[0032] Those skilled in the art should understand that the present invention is not limited to the above-mentioned embodiments. The above-mentioned embodiments and the specification only describe the principles of the present invention.
