Detailed Embodiment
[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the attached drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present utility model. Figures 1-4 On the premise of not making creative efforts, all other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model belong to the protection scope of the present utility model.
[0027] The utility model provides a technical solution: a heavy-duty RGV with adjustable conveying width, which includes a vehicle body bottom frame 1. A vehicle body driving mechanism 2 and a roller conveying mechanism 3 are arranged on the vehicle body bottom frame 1. First stoppers 4 and second stoppers 5 are fixed at the left and right edges of the roller conveying mechanism 3. A width adjusting mechanism 6 is arranged between the first stopper 4 and the second stopper 5. Among them, the vehicle body driving mechanism 2 drives the RGV to move. When the RGV transports the goods to the designated location, the goods are transmitted to the required place through the roller conveying mechanism 3, achieving a good connection and eliminating the need for manual handling of the goods. Among them, through the setting of the width adjusting mechanism 6 of the present utility model, the width of the roller conveying mechanism 3 can be adjusted to convey goods of different sizes, playing a good limiting role on the goods. In this way, during the process of transporting the goods, it is prevented that the goods move and cause damage to themselves and the RGV car, and at the same time, it is also prevented that goods with larger volume or heavier weight are unstable in the center of gravity and fall out of the RGV car during transportation, eliminating potential safety hazards.
[0028] The width adjustment mechanism 6 includes a lead screw 7. The left end of the lead screw 7 is rotatably connected to the first stop block 4, and its right end passes through the second stop block 5. A handwheel 8 is fixed to the right end of the lead screw 7. A first nut block 9 and a second nut block 10 are arranged on the lead screw 7. A first adjustment plate 11 is fixed to the first nut block 9, and a second adjustment plate 12 is fixed to the second nut block 10. Before the goods on the roller conveying mechanism 3 are transported, the width adjustment mechanism 6 is adjusted to limit the goods first. The specific operation is as follows: rotate the handwheel 8. At this time, the opposite first adjustment plate 11 and the second adjustment plate 12 will move closer to each other until there is a very small gap between the inner surfaces of the first adjustment plate 11 and the second adjustment plate 12 and the goods. This plays a very good role in limiting the goods on the roller conveying mechanism 3. Subsequently, when the roller conveying mechanism 3 transports the goods, it is not necessary to rotate the handwheel 8 again to adjust the first adjustment plate 11 and the second adjustment plate 12 to loosen the goods. In order to achieve a better limiting effect on the goods, the handwheel 8 can be rotated until the first adjustment plate 11 and the second adjustment plate 12 clamp the goods. In this way, the goods will not move at all, and the limiting effect is good. When the first adjustment plate 11 and the second adjustment plate 12 clamp the goods, it is not necessary to set a baffle and a driving mechanism for the baffle at the input end and the output end of the roller conveying mechanism 3. However, when the roller conveying mechanism 3 transports the goods subsequently, it is necessary to rotate the handwheel 8 again to adjust the first adjustment plate 11 and the second adjustment plate 12 to loosen the goods. Therefore, the above two adjustment states can be flexibly selected according to actual needs. The first adjustment plate 11 and the second adjustment plate 12 are arranged above the rollers of the roller conveying mechanism 3 and do not contact the rollers on the roller conveying mechanism 3. In this way, it does not affect the transportation of the goods by the roller conveying mechanism 3. When the lead screw 7 rotates, the first nut block 9 and the second nut block 10 on it are set to move in the opposite direction. In order to achieve automatic adjustment, the handwheel 8 can be set as a motor, and the lead screw 7 is driven to rotate by the motor to achieve automatic adjustment.
[0029] A number of width adjustment mechanisms 6 are evenly arranged between the first stop block 4 and the second stop block 5. The number of the width adjustment mechanisms 6 is set according to the actual situation. In this way, compared with only setting one width adjustment mechanism 6, the goods on the roller conveying mechanism 3 are better limited, the goods at different positions on the roller conveying mechanism 3 are evenly limited, and the limiting or clamping effect is improved.
[0030] The first adjustment plate 11 and the second adjustment plate 12 include an adjustment plate body 13. A rubber block 14 is fixed to the inner side surface of the adjustment plate body 13. Through the setting of the rubber block 14, the clamping force on the goods can be increased without damaging the goods, and while improving the clamping effect on the goods, the goods are well protected.
[0031] There are two sets of roller conveying mechanisms 3 arranged side by side. The two sets of roller conveying mechanisms 3 are separated by a partition block 15. Each set of roller conveying mechanisms 3 includes a number of rollers 16 arranged between the partition block 15 and the vehicle body bottom frame 1. One end of each roller 16 is fixed with a driven gear 17, and a transmission chain 18 is connected between adjacent driven gears 17. One of the transmission chains 18 is connected with a driving gear 19, and the driving gear 19 is connected with a first motor 20. The first motor 20 is fixed at the bottom of the vehicle body bottom frame 1. The utility model realizes large load-bearing through the setting of the double-row short stick conveying mechanism 3. When it is necessary to transmit the goods on the roller conveying mechanism 3, the first motor 20 is started. The first motor 20 drives the driving gear 19 to rotate, and then drives the driven gear 17 to rotate through the transmission chain 18, and then drives the roller 16 to rotate, so as to transmit the goods on the roller 16.
[0032] One end of a number of telescopic rods 21 is fixed on the bottom surfaces of the first adjusting plate 11 and the second adjusting plate 12, and the other end of the telescopic rods 21 is fixed on the partition block 15. The setting of the telescopic rods 21 plays a further guiding and limiting role for the first adjusting plate 11 and the second adjusting plate 12, making the entire width adjusting mechanism 6 more stable.
[0033] The lead screw 7 and the telescopic rods 21 are both arranged in the gap between two adjacent rollers 16. This setting can also prevent the goods from getting stuck in the gap between adjacent rollers 16, making the transmission of the goods by the roller conveying mechanism 3 smoother and more stable.
[0034] The vehicle body driving mechanism 2 includes a second motor 22 fixed on the vehicle body bottom frame 1. A driving shaft 23 is connected to the second motor 22. A first runner 24 and a second runner 25 are fixed on the driving shaft 23. A first track 26 matching the first runner 24 is provided below the first runner 24, and a second track 27 matching the second runner 25 is provided below the second runner 25. A third runner 28 is provided on the first track 26, and the third runner 28 is rotatably connected to the vehicle body bottom frame 1. A fourth runner 29 is provided on the second track 27, and the fourth runner 29 is rotatably connected to the vehicle body bottom frame 1. Among them, the first track 26 and the second track 27 are connected to the ground or a platform. By driving the driving shaft 23 to rotate by the second motor 22, the first runner 24 and the second runner 25 are driven to rotate, so that the first runner 24 and the second runner 25 travel along the first track 26 and the second track 27, and thus the driven wheels, the third runner 28 and the fourth runner 29 also run along the first track 26 and the second track 27.
[0035] A control cabinet 30 and a railing 31 are fixed on the vehicle body bottom frame 1, and the control cabinet 30 controls the driving of the RGV.
[0036] A collision prevention block 32 is fixed at the front end of the vehicle body bottom frame 1. The setting of the collision prevention block 32 plays a very good role in preventing collisions and provides good protection for the RGV.
[0037] Working principle: During operation, the RGV is driven to move by the vehicle body drive mechanism 2. After the RGV transports the goods to the designated location, the roller conveyor mechanism 3 is used to transport the goods to the required place, achieving a very good connection. There is no need for manual handling of the goods. The setting of the width adjustment mechanism 6 can adjust the width of the roller conveyor mechanism 3, enabling the conveyance of goods of different sizes and playing a very good role in limiting the goods. In this way, during the process of transporting the goods, it is prevented that the goods move and cause damage to themselves and the RGV car. At the same time, it is also prevented that goods with a larger volume or heavier weight are unstable in the center of gravity and fall out of the RGV car during transportation, eliminating potential safety hazards.
