[0001] The present invention relates to the field of automated warehousing and conveying, and particularly to a maintenance system for quickly transferring a shuttle car in a loop-through system. Background Art

[0002] Due to advantages such as low input cost, high system operation efficiency, and strong system expandability, the loop-through system is widely used in the field of automated warehousing and conveying.

[0003] Currently, the mainstream maintenance methods for each shuttle car in the loop-through system are to cut off the loop-through track line and use a turnout to send the shuttle car to be repaired or maintained into the maintenance track. This method not only affects the operation of other shuttle cars in the loop-through system during the rail change process, reduces the operation efficiency of the loop-through system, but also has a complex structure and high implementation cost. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a maintenance system for quickly transferring a shuttle car in a loop-through system that is stable and reliable in operation, has a high safety factor, occupies a small area, has a low cost, and can realize the quick online and offline of the shuttle car. This system can also be applied to the transformation of an already put-into-production loop-through system. During the transformation process, the original line operation is not affected, the production stop time is reduced, and the transformation cost is lowered.

[0005] To solve the above problems, the technical solution adopted by the present invention is: A maintenance system for quickly transferring a shuttle car in a loop-through system includes: a loop-through system and several shuttle cars. Each shuttle car can be arranged on the loop-through track in the loop-through system through four groups of guide wheel sets corresponding to its bottom, and each shuttle car can walk on the loop-through track under the drive of its corresponding main drive device; a sliding contact wire is installed on any guide rail of the loop-through track, and a current collector arm is arranged on each shuttle car. When the sliding contact wire is energized and the carbon brush at the end of any current collector arm contacts the sliding contact wire, the required electric energy can be obtained for the corresponding shuttle car; the structure of each group of guide wheel sets is: a guide wheel seat is fixedly arranged at the bottom of the corresponding shuttle car, two left guide wheels are arranged at intervals before and after on the left part of the guide wheel seat, two right guide wheels are arranged at intervals before and after on the right part of the guide wheel seat, and a guide wheel spacing adjusting mechanism is arranged between the guide wheel seat and the two left guide wheels and the two right guide wheels to adjust the spacing between the two left guide wheels and the two right guide wheels through the guide wheel spacing adjusting mechanism; each current collector arm is installed on the corresponding shuttle car through a position adjusting mechanism, and whether the carbon brush at the end of the current collector arm contacts the sliding contact wire is adjusted through the position adjusting mechanism; a maintenance track and a crane for lifting any shuttle car are arranged outside the loop-through track of the loop-through system.

[0006] Further, in a maintenance system for a fast transfer shuttle car in loop threading, the structure of the guide wheel spacing adjusting mechanism is as follows: Two left push-pull electromagnets are arranged at intervals in the front and rear of the left part of the guide wheel seat, and a left guide wheel is fixedly installed on the push rod of each left push-pull electromagnet; Two right push-pull electromagnets are arranged at intervals in the front and rear of the right part of the guide wheel seat, and a right guide wheel is fixedly installed on the push rod of each right push-pull electromagnet. The working principle of the above guide wheel spacing adjusting mechanism is as follows: When the two left push-pull electromagnets and the two right push-pull electromagnets are both energized, the push rods of the two left push-pull electromagnets move to the left, so that the two left guide wheels are away from the left running surface of the corresponding guide rail on the loop threading track, and the push rods of the two right push-pull electromagnets move to the right, so that the two right guide wheels are away from the right running surface of the corresponding guide rail on the loop threading track; When the two left push-pull electromagnets and the two right push-pull electromagnets are both de-energized, the push rods of the two left push-pull electromagnets move back to their original positions to the right, so that the two left guide wheels are in rolling contact with the left running surface of the corresponding guide rail on the loop threading track, and the push rods of the two right push-pull electromagnets move back to their original positions to the left, so that the two right guide wheels are in rolling contact with the right running surface of the corresponding guide rail on the loop threading track.

[0007] Further, in a maintenance system for a fast transfer shuttle car in loop threading, the front left guide wheel and the front right guide wheel are symmetrically arranged left and right with respect to the center line of the guide wheel seat, and the rear left guide wheel and the rear right guide wheel are symmetrically arranged left and right with respect to the center line of the guide wheel seat.

[0008] Further, in a maintenance system for a fast transfer shuttle car in loop threading, the structure of the position adjusting mechanism is as follows: A connecting plate is fixedly arranged on each shuttle car, two push-pull electromagnets are arranged at intervals up and down on the connecting plate, and the push rod of each push-pull electromagnet is connected to the collector arm mounting bracket, and the collector arm is mounted on the collector arm mounting bracket. The working principle of the above position adjusting mechanism is as follows: When the two push-pull electromagnets are both energized, the push rods of the two push-pull electromagnets drive the collector arm mounting bracket to move, so that the carbon brush at the end of the collector arm is away from the sliding contact wire; When the two push-pull electromagnets are both de-energized, the push rods of the two push-pull electromagnets drive the collector arm mounting bracket to move, so that the carbon brush at the end of the collector arm returns to its original position and contacts the sliding contact wire.

[0009] Further, in a maintenance system for a fast transfer shuttle car in loop threading, car stops for preventing the shuttle car walking on the maintenance track from derailing are respectively arranged at both ends of the maintenance track.

[0010] Further, the aforementioned maintenance system for quickly transferring shuttle vehicles in a ring-through, wherein the crane is a rope crane, and the sling on the rope crane adopts a grab-type sling; the structure of the grab-type sling includes: a sling support connected to the lifting rope of the rope crane, one end of a left connecting arm is hinged to the left part of the sling support, the other end of the left connecting arm is hinged to the left gripper, one end of the left gripper is a left gripping end, and the other end of the left gripper is hinged to the left end portion of the middle connecting rod; one end of a right connecting arm is hinged to the right part of the sling support, the other end of the right connecting arm is hinged to the right gripper, one end of the right gripper is a right gripping end, and the other end of the right gripper is hinged to the right end portion of the middle connecting rod; a pulley is installed in the middle of the middle connecting rod, a motor is installed on the rope crane, the motor shaft of the motor is connected to the drum, one end of the opening and closing rope is fixed to the rope crane, and the other end of the opening and closing rope is fixed to the drum after being wound around the pulley. The working principle of the grab bucket spreader is as follows: When the motor starts and drives the drum to wind the opening and closing rope around the drum, it drives the middle connecting rod to move upward relative to the sling support, the left clamping end of the left gripper swings inward, and the right clamping end of the right gripper swings inward, thereby clamping the shuttle car; when the motor starts and separates the opening and closing rope wound around the drum from the drum, the middle connecting rod moves downward relative to the sling support, the left clamping end of the left gripper swings outward, and the right clamping end of the right gripper swings outward, thereby releasing the clamped shuttle car.

[0011] Furthermore, in the aforementioned maintenance system for quickly transferring shuttle vehicles in a loop, a temporary parking area is divided on the loop track of the loop system; the crane and each shuttle vehicle are controlled by a remote control system. The steps of transferring the shuttle vehicle located in the temporary parking area to the maintenance track are: The remote control system is operated to control the guide wheel spacing adjustment mechanism on the shuttle vehicle located in the temporary parking area to increase the spacing between the two left guide wheels and the two right guide wheels in each guide wheel group on the shuttle vehicle, so that the two left guide wheels are away from the left running surface of the corresponding guide rail on the loop track, and the two right guide wheels are away from the right running surface of the corresponding guide rail on the loop track; The remote control system is operated to control the position adjustment mechanism on the shuttle vehicle located in the temporary parking area, so that the carbon brush at the end of the collector arm on the shuttle vehicle located in the temporary parking area is away from the busbar; The remote control system is used to control the crane to grab the shuttle vehicle located in the temporary parking area and then lift the shuttle vehicle onto the maintenance track; Operate the remote control system to control the guide wheel spacing adjustment mechanism on the shuttle located on the maintenance track, and reduce the spacing between the two left guide wheels and the two right guide wheels on the shuttle to the original position, so that the two left guide wheels rollingly contact the left walking surface of the corresponding guide rail on the maintenance track, and the two right guide wheels rollingly contact the right walking surface of the corresponding guide rail on the maintenance track.

[0012] The steps to transfer the shuttle located on the maintenance track to the temporary parking area on the loop track are as follows: Operate the remote control system to control the guide wheel spacing adjustment mechanisms on the shuttle located on the maintenance track, and increase the spacing between the two left guide wheels and the two right guide wheels in each set of guide wheel groups on the shuttle, so that the two left guide wheels are away from the left walking surface of the corresponding guide rail on the maintenance track, and the two right guide wheels are away from the right walking surface of the corresponding guide rail on the maintenance track; Operate the remote control system to control the position adjustment mechanism on the shuttle located on the maintenance track, so that the carbon brush at the end of the current collector arm on the shuttle located on the maintenance track moves outwards; After operating the remote control system to control the crane to grasp the shuttle located on the maintenance track, lift the shuttle to the temporary parking area on the loop track; Operate the remote control system to control the guide wheel spacing adjustment mechanism on the shuttle lifted to the temporary parking area, and reduce the spacing between the two left guide wheels and the two right guide wheels on the shuttle to the original position, so that the two left guide wheels rollingly contact the left walking surface of the corresponding guide rail on the loop track, and the two right guide wheels rollingly contact the right walking surface of the corresponding guide rail on the loop track; Operate the remote control system to control the position adjustment mechanism on the shuttle lifted to the temporary parking area, so that the carbon brush at the end of the current collector arm on the shuttle moves inwards, and the carbon brush at the end of the current collector arm on the shuttle contacts the trolley wire.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.

[0026] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, an indirect connection through an intermediate medium, or a communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] A maintenance system for a rapid transfer shuttle in a loop-through, as described in this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, includes: a loop-through system and several shuttles 2. Each shuttle 2 can be arranged on a loop-through track 1 in the loop-through system through four sets of guide wheel groups 6 corresponding to its bottom, and each shuttle 2 can travel on the loop-through track 1 under the drive of its corresponding main drive device. A trolley wire 12 is installed on any guide rail 11 of the loop-through track 1, and a current collector arm 73 is arranged on each shuttle 2. When the trolley wire 12 is energized and the carbon brush at the end of any current collector arm 73 contacts the trolley wire 12, the required electric energy can be obtained for the corresponding shuttle 2.

[0028] The structure of each set of guide wheel groups 6 is: a guide wheel seat 65 is fixedly arranged at the bottom of the corresponding shuttle 2. Two left guide wheels 63 are arranged at intervals before and after at the left part of the guide wheel seat 65, and two right guide wheels 64 are arranged at intervals before and after at the right part of the guide wheel seat 65. A guide wheel spacing adjustment mechanism is arranged between the guide wheel seat 65 and the two left guide wheels 63 and the two right guide wheels 64 to adjust the spacing between the two left guide wheels 63 and the two right guide wheels 64. As Figure 5 and Figure 6 shown, the structure of the guide wheel spacing adjustment mechanism in this embodiment is: two left push-pull electromagnets 61 are arranged at intervals before and after at the left part of the guide wheel seat 65, and a left guide wheel 63 is fixedly installed on the push rod of each left push-pull electromagnet 61; two right push-pull electromagnets 62 are arranged at intervals before and after at the right part of the guide wheel seat 65, and a right guide wheel 64 is fixedly installed on the push rod of each right push-pull electromagnet 62.

[0029] A more preferred solution is: the left guide wheel at the front side and the right guide wheel at the front side are symmetrically arranged left and right with respect to the center line of the guide wheel seat 65, and the left guide wheel at the rear side and the right guide wheel at the rear side are symmetrically arranged left and right with respect to the center line of the guide wheel seat 65.

[0030] Each current collector arm 73 is mounted on the corresponding shuttle car 2 through a position adjusting mechanism, and the position adjusting mechanism is used to adjust whether the carbon brush at the end of the current collector arm 73 contacts the sliding contact wire 12. As Figure 3 , Figure 4 and Figure 7 shown, in this embodiment, the structure of the position adjusting mechanism is as follows: A connecting plate 7 is fixedly arranged on each shuttle car 2, and two push-pull electromagnets 72 are arranged at intervals up and down on the connecting plate 7. The push rods of each push-pull electromagnet 72 are connected to the current collector arm mounting bracket 71, and the current collector arm 73 is mounted on the current collector arm mounting bracket 71.

[0031] When it is necessary to remove any shuttle car 2 from the loop-through track 1, the two left push-pull electromagnets 61 and the two right push-pull electromagnets 62 on this shuttle car 2 are energized. The push rods of the two left push-pull electromagnets 61 move to the left, so that the two left guide wheels 63 are away from the left running surface of the corresponding guide rail 11 on the loop-through track 1. The push rods of the two right push-pull electromagnets 62 move to the right, so that the two right guide wheels 64 are away from the right running surface of the corresponding guide rail 11 on the loop-through track 1, and the two push-pull electromagnets 72 on this shuttle car 2 are energized. The push rods of the two push-pull electromagnets 72 drive the current collector arm mounting bracket 71 to move, so that the carbon brush at the end of the current collector arm 73 is away from the sliding contact wire 12. At this time, the two left guide wheels 63, the two right guide wheels 64 and the current collector arm 73 will not interfere with the removal of the shuttle car 2 from the loop-through track 1, and at this time, the shuttle car 2 can be successfully removed.

[0032] After the shuttle car in the above state is re-placed on the loop-through track 1, the two left push-pull electromagnets 61 and the two right push-pull electromagnets 62 on this shuttle car 2 are de-energized. The push rods of the two left push-pull electromagnets 61 return to their original positions to the right, so that the two left guide wheels 63 are in rolling contact with the left running surface of the corresponding guide rail 11 on the loop-through track 1. The push rods of the two right push-pull electromagnets 62 return to their original positions to the left, so that the two right guide wheels 64 are in rolling contact with the right running surface of the corresponding guide rail 11 on the loop-through track 1. And the two push-pull electromagnets 72 on this shuttle car 2 are de-energized. The push rods of the two push-pull electromagnets 72 drive the current collector arm mounting bracket 71 to move, so that the carbon brush at the end of the current collector arm 73 returns to its original position and contacts the sliding contact wire. At this time, this shuttle car 2 is again movably arranged on the loop-through track 1, and driven by its own main drive device, this shuttle car 2 can run on the loop-through track 1.

[0033] In summary, through the guide wheel spacing adjusting mechanism and the position adjusting mechanism, the purpose of quickly loading and unloading the shuttle car 2 can be achieved. During the transfer process, there is no need to cut off the main track, which does not affect the normal operation of other shuttle cars in the loop-through system. The operation is stable and reliable, and the construction cost is relatively low.

[0034] AsFigure 1 and Figure 2 As shown, in this embodiment, a maintenance track 4 is arranged outside the loop track 1 of the loop system, and vehicle stops 41 are respectively arranged at both ends of the maintenance track 4 to prevent the shuttle vehicle running on the maintenance track 4 from derailing.

[0035] like Figure 1 and Figure 2 As shown, in this embodiment, a crane 5 for lifting any shuttle vehicle 2 is arranged outside the loop track 1 of the loop system, and the crane 5 is a rope crane, specifically a light gantry crane. The sling mounted on the lifting rope of the rope crane is a grab bucket sling.

[0036] like Figure 8 and Figure 9 As shown, the structure of the grab type sling in this embodiment includes: a sling support 8 connected to the lifting rope 51 of the rope crane, one end of a left connecting arm 81 is hinged to the left part of the sling support 8, and the other end of the left connecting arm 81 is hinged to the left part of the sling support 8, and one end of the left connecting arm 81 is hinged to the left claw 82, one end of the left claw 82 is the left clamping end 821, and the other end of the left claw 82 is hinged to the left end part of the middle connecting rod 83; one end of a right connecting arm 86 is hinged to the right part of the sling support 8, and the other end of the right connecting arm 86 is hinged to the right claw 87, one end of the right claw 87 is the right clamping end 871, and the other end of the right claw 87 is hinged to the right end part of the middle connecting rod 83. A pulley 84 is installed in the middle of the middle connecting rod 83, and a motor is installed on the rope crane. The motor shaft of the motor is connected to the drum. One end of the opening and closing rope 85 is fixed to the rope crane, and the other end of the opening and closing rope 85 is wound around the pulley 84 and then fixed to the drum.

[0037] When the shuttle 2 needs to be clamped, the motor is started to drive the drum to wind the opening and closing rope 85 around the drum, which drives the middle connecting rod 83 to move upward relative to the hanger support 8, and the left clamping end of the left claw 82 swings inward, and the right clamping end of the right claw 87 swings inward, thereby clamping the shuttle 2. Figure 9 The schematic diagram is a state diagram of the grab bucket type spreader grabbing and clamping the shuttle vehicle 2.

[0038] When it is necessary to release the clamped shuttle 2, the motor is started to separate the opening and closing rope 85 wound on the drum from the drum, and the middle connecting rod 83 moves downward relative to the hanger support 8, the left clamping end of the left claw 82 swings outward, and the right clamping end of the right claw 87 swings outward, thereby releasing the clamped shuttle 2. Figure 8 The diagram shows a state diagram of the grab bucket spreader releasing the shuttle car 2.

[0039] like Figure 2As shown in the figure, in this embodiment, a temporary parking area 3 is demarcated on the loop track 1 of the loop-through system. The shuttle cars 2 that need to be repaired or maintained are uniformly moved to the temporary parking area 2, and then lifted onto the maintenance track 4 by a crane 5. When the repaired and maintained shuttle cars 2 rejoin the loop-through system, they are lifted to the temporary parking area by the crane 5 and then join the loop-through operation. The crane 5 and each shuttle car 2 are controlled by a remote control system. By controlling the crane 5 and each shuttle car 2 through the remote control system, remote lifting can be achieved, avoiding personnel from entering the loop-through operation area and reducing safety risks.

[0040] The steps of transferring the shuttle car 2 located in the temporary parking area 3 to the maintenance track 4 are as follows: Manipulate the remote control system to control the distance adjustment mechanism of each set of guide wheels on the shuttle car 2 located in the temporary parking area 3, and increase the distance between the two left guide wheels 63 and the two right guide wheels 64 in each set of guide wheel groups on the shuttle car, so that the two left guide wheels 63 are away from the left running surface of the corresponding guide rail 11 on the loop track 1, and the two right guide wheels 64 are away from the right running surface of the corresponding guide rail 11 on the loop track 1. That is: energize the two left push-pull electromagnets 61 and the two right push-pull electromagnets 62 on the shuttle car 2, the push rods of the two left push-pull electromagnets 61 move to the left, so that the two left guide wheels 63 are away from the left running surface of the corresponding guide rail 11 on the loop track 1, and the push rods of the two right push-pull electromagnets 62 move to the right, so that the two right guide wheels 64 are away from the right running surface of the corresponding guide rail 11 on the loop track 1.

[0041] Manipulate the remote control system to control the position adjustment mechanism on the shuttle car 2 located in the temporary parking area 3, so that the carbon brush at the end of the current collector arm 72 on the shuttle car 2 located in the temporary parking area 3 is away from the sliding contact wire 12. That is: energize the two push-pull electromagnets 72 on the shuttle car 2, and the push rods of the two push-pull electromagnets 72 drive the current collector arm mounting bracket 71 to move, so that the carbon brush at the end of the current collector arm 73 is away from the sliding contact wire 12.

[0042] After manipulating the remote control system to control the crane 5 to grip the shuttle car 2 located in the temporary parking area 3, lift the shuttle car 2 onto the maintenance track 4; manipulate the remote control system to control the distance adjustment mechanism of the guide wheels on the shuttle car 2 lifted onto the maintenance track 4, and reduce the distance between the two left guide wheels and the two right guide wheels on the shuttle car to the original position, so that the two left guide wheels roll into contact with the left running surface of the corresponding guide rail on the maintenance track, and the two right guide wheels roll into contact with the right running surface of the corresponding guide rail on the maintenance track. At this time, the shuttle car 2 is successfully transferred from the temporary parking area 3 to the maintenance track 4. During the transfer process, there is no need to cut off the main track, and the normal operation of other shuttle cars in the loop-through system is not affected during the transfer process. The operation is stable and reliable, and the construction cost is relatively low.

[0043] The steps for transferring the shuttle car 2 located on the maintenance track 4 to the temporary parking area 3 on the loop-through track 1 are as follows: Manipulate the remote control system to control the guide wheel spacing adjustment mechanisms on the shuttle car 2 located on the maintenance track 4, and increase the spacing between the two left guide wheels 63 and the two right guide wheels 64 in each set of guide wheel groups on the shuttle car, so that the two left guide wheels 63 are away from the left running surface of the corresponding guide rail on the maintenance track 4, and the two right guide wheels 64 are away from the right running surface of the corresponding guide rail on the maintenance track 4. That is: energize the two left push-pull electromagnets 61 and the two right push-pull electromagnets 62 on the shuttle car 2, the push rods of the two left push-pull electromagnets 61 move to the left, so that the two left guide wheels 63 are away from the left running surface of the corresponding guide rail on the maintenance track 4, and the push rods of the two right push-pull electromagnets 62 move to the right, so that the two right guide wheels 64 are away from the right running surface of the corresponding guide rail on the maintenance track 4.

[0044] Manipulate the remote control system to control the position adjustment mechanism on the shuttle car 2 located on the maintenance track 4, so that the carbon brush at the end of the current collector arm 73 on the shuttle car 2 located on the maintenance track 4 moves outwards.

[0045] Manipulate the remote control system to control the crane 5 to grip the shuttle car 2 located on the maintenance track 1, and then lift the shuttle car 2 to the temporary parking area 3 on the loop-through track 1.

[0046] Manipulate the remote control system to control the guide wheel spacing adjustment mechanism on the shuttle car 2 lifted to the temporary parking area 3, and reduce the spacing between the two left guide wheels 63 and the two right guide wheels 64 on the shuttle car 2 to the original position, so that the two left guide wheels 63 are in rolling contact with the left running surface of the corresponding guide rail 11 on the loop-through track 1, and the two right guide wheels 64 are in rolling contact with the right running surface of the corresponding guide rail 11 on the loop-through track 1.

[0047] Manipulate the remote control system to control the position adjustment mechanism on the shuttle car 2 lifted to the temporary parking area 3, so that the carbon brush at the end of the current collector arm 73 on the shuttle car 2 moves inwards, and the carbon brush at the end of the current collector arm 73 on the shuttle car 2 contacts the trolley wire 12. At this time, the shuttle car 2 can be added to the loop-through system for loop-through work.

[0048] The above system has the following main advantages: First, it can achieve the purpose of quickly loading and unloading the shuttle car 2 for maintenance or repair. During the transfer process, there is no need to cut off the loop track 1, which does not affect the normal operation of other shuttle cars 2 in the loop system. It runs stably and reliably, and the construction cost is relatively low. Second, by controlling the crane 5 and each shuttle car 2 through the remote control system, remote lifting can be achieved, avoiding personnel entering the loop operation area, reducing safety risks, and having a high safety factor. Third, the maintenance system has a compact structure, occupies a small area, and has a low implementation cost. Fourth, this system can also be applied to the transformation of the already put-into-production loop system. During the transformation process, it does not affect the operation of the original line, reduces the downtime, and lowers the transformation cost.

[0049] The above description is only a preferred embodiment of the present invention, and does not impose any other form of limitation on the present invention. Any modification or equivalent change made according to the technical essence of the present invention still falls within the scope of protection required by the present invention.
