DETAILED DESCRIPTION

[0020] like Figure 1-3 As shown, a circular rail operation mechanism based on a turning stacker and a method thereof, comprising two rails 1 arranged opposite to each other in the vertical direction, the lower rail 1 being fixedly installed on the ground, and the upper rail 1 being fixed on an external bracket, a support frame 3 being arranged between the upper and lower rails 1, a loading platform 301 being slidably arranged on the support frame 3, a telescopic fork being fixedly installed on the top of the loading platform 301, when actually used, a reel can be installed below the support frame 3, a rope is fixedly arranged between the reel and the loading platform 301, and the reel is driven by an external lifting motor to drive the loading platform 301 to move in the vertical direction, of course, the loading platform 301 can also be driven to move by driving the chain to move, as it is a mature technical means in the mechanical field, it will not be described in detail here; The top and bottom ends of the support frame 3 are fixedly provided with mounting seats 5, which are in a U-shaped structure as a whole, and the wheel boxes 2 that match the track 1 are rotatably installed at both ends of the mounting seat 5, and the running wheels 9 are installed in the wheel boxes 2. Figure 5As shown, a transverse axis 15 is provided at the running wheel 9, the transverse axis 15 passes through the running wheel 9 and is fixedly connected thereto, and one end of the transverse axis 15 passes through the wheel box 2 and rotates therewith, the running wheel 9 is located on the side of the track 1 close to the support frame 3 and is in contact with the track 1. In addition, two groups of guide wheels 4 are installed on the side of the wheel box 2 close to the track 1, the guide wheels 4 are rotatably connected to the wheel box 2, and the guide wheels 4 are located on the inner and outer sides of the track 1. The provided guide wheels 4 are conducive to limiting the wheel box 2, so that it can slide stably on the track 1. Of course, power can be applied to one group of running wheels 9 to drive the support frame 3 to move along the track 1. Specifically, a motor can be installed on this wheel box 2, and the output shaft of the motor is connected to one end of the transverse axis 15 passing through the wheel box 2, so as to drive the running wheel 9 to rotate, thereby driving the support frame 3 to move.

[0021] In actual use, due to various reasons, slippage may occur between the running wheel 9 and the track 1. For example, when there is oil stain somewhere on the surface of the track 1, ice may appear somewhere on the track 1 in cold weather, or because a certain part of the surface of the track 1 is concave, these situations will cause the running wheel 9 to slip, so that the running wheel 9 cannot stably drive the support frame 3 to move along the track 1. In order to solve this problem, in this solution, a storage box 6 is fixedly installed on one of the wheel boxes 2 located below. Of course, in specific applications, the storage box 6 is fixedly connected to the wheel box 2 equipped with a motor, and the storage box 6 is A rack 26 is provided in the mounting seat 5 on one side thereof, and a driven gear 14 matching the rack 26 is provided at the wheel box 2 equipped with the motor. In actual use, when the running wheel 9 moves to a certain place on the track 1 and slips, the rack 26 in the storage box 6 and the mounting seat 5 will fall and be stuck on the track 1, and the motor can synchronously drive the driven gear 14 to rotate in the process of driving the running wheel 9 to rotate. As the support frame 3 moves, the driven gear 14 will overlap with the rack 26 in the vertical direction, so that the support frame 3 can be stably driven to move stably on the track 1 through the meshing of the driven gear 14 and the rack 26.

[0022] Reference Figure 6 As shown, in order to enable the rack 26 to be clamped on the rail 1, a connecting plate 22 is fixedly installed at the bottom of the rack 26, and a storage slot for installing the connecting plate 22 is opened in the storage box 6 and the mounting seat 5. In addition, a through slot 7 for leading out the connecting plate 22 is opened on the bottom surface of the storage box 6 and the mounting seat 5; Further, refer to Figure 8-10As shown, a slide bar 27 is slidably provided on the bottom surface of the connecting plate 22, and a plug rod 20 is fixedly provided at both ends of the bottom surface of the slide bar 27. Specifically, a slide groove slidably matched with the slide bar 27 is provided on the bottom surface of the connecting plate 22, and the cross-sections of the slide groove and the slide bar 27 are both set to be T-shaped. A block 28 is elastically provided on the top surface of the slide bar 27, and the top of the block 28 is an arc surface 2801, and the two sides of the block 28 are vertical portions 2802. The inner cavity of the slide groove A card slot 2204 is provided at the top wall. In the initial state, the top of the card block 28 is inserted into the card slot 2204, but the vertical parts 2802 on both sides of the card block 28 are located outside the card slot 2204. Positioning slots 2203 are also provided on both sides of the card slot 2204 on the top wall of the inner cavity of the slide groove. The depth of the positioning slot 2203 is greater than the depth of the card slot 2204. When the card block 28 pops out and is inserted into the positioning slot 2203, the slide bar 27 and the connecting plate 22 are completely locked. Reference Figure 3 As shown, the cross section of the track 1 is set to be T-shaped, and a hole 102 matching the plug rod 20 is opened on the top surface of the horizontal section of the track 1. The distance between two adjacent holes 102 is equal to the distance between the two plug rods 20 on the slide 27. Figure 7 As shown, when the connecting plate 22 falls from the through slot 7 and the insertion rod 20 is not inserted into the insertion hole 102, the connecting plate 22 is not offset from the through slot 7 in the vertical direction. At this time, the movement of the support frame 3 can synchronously drive the connecting plate 22 to move. When the insertion rod 20 is aligned with the insertion hole 102, the connecting plate 22 can fall further, so that the connecting plate 22 is completely moved out of the through slot 7. At this time, the rack 26 on the top of the connecting plate 22 is lower than the position of the guide wheel 4 in the vertical direction, so as to avoid interference between the guide wheel 4 and the rack 26 when moving.

[0023] In order to limit the connection plate 22, limit strips 23 are provided on both side walls of the storage tank. Figure 6-8 As shown, limiting grooves 2201 cooperating with the limiting strips 23 are provided at both ends of the connecting plate 22. When the connecting plate 22 is located above the through groove 7, the limiting strips 23 can be inserted into the limiting grooves 2201 to limit the connecting plate 22. Furthermore, a first electromagnet 24 is provided on the outer side of the limit strip 23, and the first electromagnet 24 is elastically connected to the limit strip 23, and the limit strip 23 is made of iron. When the first electromagnet 24 is energized, it can attract the limit strip 23, so that the limit strip 23 and the limit groove 2201 are offset, so that the connecting plate 22 can be guided out from the through groove 7.

[0024] Reference Figure 5As shown, in order for the horizontal shaft 15 to synchronously drive the driven gear 14 to rotate, a main gear 10 is fixedly sleeved on one end of the horizontal shaft 15, and a slide bar 13 is installed at the wheel box 2, and the slide bar 13 can slide relative to the wheel box 2, and the above-mentioned driven gear 14 is fixedly sleeved on the outside of the slide bar 13. In addition, a sub-gear 11 meshing with the main gear 10 is also fixedly sleeved on the outside of the slide bar 13, and the width of the sub-gear 11 is greater than the width of the main gear 10, and the outer diameter of the above-mentioned driven gear 14 is equal to the outer diameter of the running wheel 9.

[0025] In specific applications, detection units can be installed on the transverse shafts 15 on the running wheels 9 on both sides. Specifically, the detection unit can be a speed sensor or a speedometer to detect the speed of the two running wheels 9, so as to further obtain the speed difference between the two running wheels 9. When the speed difference between the two running wheels 9 reaches a threshold, the first electromagnet 24 can be triggered to energize it, thereby releasing the connecting plate 22 to engage it with the track 1.

[0026] In actual use, the motor drives the running wheel 9 to rotate, and the friction between the running wheel 9 and the track 1 can drive the support frame 3 to slide along the track 1, thereby driving the support frame 3 to move in front of the corresponding goods, and the telescopic fork on the loading platform 301 can be used to pick up the goods; When the wheel box 2 moves to a certain point on the track 1 and causes the running wheel 9 to slip, the moving speed of the support frame 3 will decrease. At this time, the speed of the running wheel 9 driven by the motor remains unchanged, but the unpowered running wheel 9 on the other side rotates with the movement of the support frame 3. Therefore, when the moving speed of the support frame 3 decreases, the speed of the running wheel 9 on the other side will also decrease accordingly, resulting in a speed difference between the running wheels 9 on both sides. According to the above description, when the speed difference between the two running wheels 9 reaches a set threshold, the first electromagnet 24 can be energized, and the suction force of the first electromagnet 24 on the limit bar 23 makes the limit bar 23 staggered with the limit groove 2201 on the connecting plate 22, so that the connecting plate 22 can fall from the through groove 7. If the insertion rod 20 is not inserted into the inside of the insertion hole 102, the connecting plate 22 is in a state as follows. Figure 7 The state shown, that is, the connecting plate 22 is not completely guided out of the through slot 7. At this time, the movement of the support frame 3 can synchronously drive the connecting plate 22 to move. When the insertion rod 20 is aligned with the insertion hole 102, the connecting plate 22 can fall again, and the insertion rod 20 can be locked on the track 1 through the cooperation between the insertion rod 20 and the insertion hole 102; Afterwards, as the support frame 3 moves, the driven gear 14 will overlap with the rack 26 in the vertical direction. At this time, the meshing of the driven gear 14 and the rack 26 can cause the rack 26 to move relative to the slide bar 27. Since the top of the block 28 is an arc surface 2801, the top of the block 28 can be moved out of the slot 2204. However, as the connecting plate 22 and the rack 26 move, the block 28 will overlap with the positioning slot 2203. Since the positioning slot 2203 is deeper, the top of the block 28 can be further inserted into the positioning slot 2203, so that the vertical portions 2802 on both sides of the block 28 are also Entering into the positioning groove 2203, the slide bar 27 and the connecting plate 22 are completely locked. At this time, the driven gear 14 can drive the support frame 3 to move along the track 1 by utilizing the engagement between the driven gear 14 and the rack 26 during the rotation of the running wheel 9. Since the rack 26 and the connecting plate 22 move backward a certain distance relative to the track 1, it is beneficial for the rack 26 to cover the slipping position on the track 1, so that the next time the running wheel 9 enters the slipping area, the driven gear 14 will engage with the rack 26, thereby driving the support frame 3 to move stably along the track 1.

[0027] In summary, this device is provided with a rack 26 on both the storage box 6 and the mounting base 5. When the running wheel 9 slips somewhere on the track 1, the rack 26 can fall and be engaged on the track 1, thereby driving the support frame 3 to move stably on the track 1 through the engagement between the driven gear 14 at the wheel box 2 and the rack 26.

[0028] like Figure 6-10 As shown, in order to install multiple sets of connecting plates 22 in the storage tank, the present solution provides guide grooves 21 connected to the through grooves 7 on the bottom surfaces of the storage box 6 and the mounting seat 5. Figure 6 As shown, the insertion rods 20 at the bottom of the multiple groups of connecting plates 22 in the storage tank are all located in the guide grooves 21; In order to drive the connection plate 22 to move, an inclined inclined plate 17 is fixedly provided in the storage groove, and a pressure block 18 is slidably provided on the bottom surface of the inclined plate 17. Specifically, a slider is fixedly provided on the top surface of the pressure block 18, and the cross section of the slider is set to be T-shaped. The bottom surface of the inclined plate 17 is provided with a T-shaped groove that slides with the slider. A positioning rod 19 is provided on one side above the through groove 7. The positioning rod 19 is fixedly installed on the inner wall of the storage groove. In actual use, when the first electromagnet 24 is energized to make the limit bar 23 staggered with the limit groove 2201, the connection plate 22 at the head end will fall out through the through groove 7. At this time, the pressing block 18 will slide downward along the inclined plate 17 and drive multiple groups of connecting plates 22 to move toward the direction of the positioning rod 19. When the next connecting plate 22 moves to the through slot 7, the limiting groove 2201 at its end will cooperate with the limiting strip 23 to prevent it from falling through the through slot 7. When the connecting plate 22 slides to the positioning rod 19, it stops moving. At this time, the connecting plate 22 is aligned with the through slot 7 in the vertical direction. Through this structure, it is convenient to install multiple groups of connecting plates 22. When there are multiple positions on the track 1 that cause the running wheel 9 to slip, this device can be used for them.

[0029] Here, the electrical components for detecting the rotational speed of the running wheels 9 are further explained: first, the rotational speeds of the running wheels 9 on both sides are detected by a rotational speed sensor or a speed meter, and the detected signals are amplified and filtered, and then the rotational speeds of the running wheels 9 on both sides are compared to obtain the rotational speed difference between the two running wheels 9. When the rotational speed difference reaches a threshold, the first electromagnet 24 is triggered. Of course, the output end of the above-mentioned rotational speed sensor or speed meter can be connected to a controller (such as a PLC or a single-chip microcomputer, etc.), so as to facilitate the control of the first electromagnet 24. The specific circuit connection and working principle are mature technical means in the electrical field and will not be elaborated here.

[0030] Reference Figure 2 As shown, a rotating shaft 201 is fixedly arranged on the top surface of the wheel box 2, and the rotating shaft 201 and the mounting seat 5 are rotatably matched through a bearing. Through this structure, the wheel box 2 can be prevented from getting stuck at the turning point of the track 1.

[0031] Reference Figure 3-4 As shown, the track 1 is a runway-shaped structure as a whole, and gaskets 101 are fixedly arranged at both ends of the track 1, the gaskets 101 are located on the inner side of the track 1, and a switch 8 is installed at the bottom end of the guide wheel 4 located on the inner side of the track 1; Reference Figure 6-8As shown, a strip groove 2202 is further provided at the end of the connecting plate 22, and a clamping strip 25 matching the strip groove 2202 is provided at the inner wall of the storage box 6, and a second electromagnet is provided on the outer side of the clamping strip 25. The switch 8 is connected to the second electromagnet through a signal connection. A magnetic plate is fixedly embedded at one end of the clamping strip 25 close to the second electromagnet. When the second electromagnet is energized, the magnetic plate has the same magnetic pole on the side opposite to the second electromagnet. In actual use, when the running wheel 9 moves to the two end positions of the track 1, the switch 8 contacts the gasket 101, thereby controlling the second electromagnet to be energized, so that the clamping strip 25 can be pushed out to make it stuck in the strip groove 2202, so as to prevent the connecting plate 22 from falling at the two end positions of the track 1.

[0032] like Figure 5 As shown, a fixing plate 16 is fixedly arranged in the wheel box 2, the fixing plate 16 is located on both sides of the running wheel 9, and the transverse axis 15 passes through the fixing plate 16 and rotates with the fixing plate 16 through a bearing.

[0033] A boss 29 is fixedly provided on the bottom surface of the wheel box 2, so that the slide rod 13 passes through the boss 29 and slides with it. An L-shaped baffle is fixedly provided on the outer side of the wheel box 2, so that the slide rod 13 passes through the baffle and slides with it. A baffle ring 12 is fixedly provided on the outer side of the slide rod 13, and a limit spring is provided between the baffle ring 12 and the baffle. The limit spring can be sleeved on the outer side of the slide rod 13. Through this structure, the driven gear 14 can be prevented from interfering with the track 1 when the wheel box 2 turns.
