[0002] When a shuttle is transporting goods on the track, if an unexpected situation such as a power outage or insufficient power occurs, causing the shuttle to stop on the track and obstructing the normal operation of other shuttles, the common shuttle rescue tool is to use a normal shuttle to move the faulty shuttle to the repair site by pushing or pulling. However, due to the flatness of the track and the force between the shuttle and the track, the process of moving the faulty shuttle is very difficult, increasing the difficulty of repair. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, this utility model provides a rescue structure for a malfunctioning shuttle car, which can completely avoid the huge obstruction between the malfunctioning shuttle car and the running track after the malfunctioning shuttle car stops running, so that the rescue shuttle car can smoothly transport the malfunctioning shuttle car on the running track to the maintenance point for repair.

[0004] Technical solution: To achieve the above objectives, the present invention provides a rescue structure for a malfunctioning shuttle, comprising a running track, a shuttle, and a rescue tool. The shuttle is disposed inside the running track. The rescue tool can be detachably installed on the upper end of any local position on the running track. The rescue tool installed on the upper end of any local position on the running track can be detachably connected to the upper end of the shuttle in the running track at that position. The rescue tool can lift and release the shuttle connected below.

[0005] Furthermore, assuming the shuttle's height in its non-lifted state is H, the rescue tool can raise the shuttle connected below to a height of at least H.

[0006] Furthermore, the travel track is a double track, which includes a first track and a second track that are symmetrically arranged on the left and right. The shuttle car rolls and is guided between the first track and the second track, and the rescue tools are set up on the upper end of the first track and the second track.

[0007] Furthermore, the rescue tools include lifting brackets, chuck blocks, and climbing rods. The lifting brackets are vertically mounted above the first and second tracks. Each lifting bracket has a vertical climbing rod movably installed at both ends. The lifting brackets can be adjusted up and down relative to the two climbing rods. The lower ends of the two climbing rods are connected to chuck blocks, which can be fixedly locked above the first and second tracks respectively.

[0008] Furthermore, at least one of the two climbing rods is a threaded rod, with the externally threaded climbing rod engaging with the threaded hole on the lifting bracket, and the lower end of the climbing rod being rotatably connected to a claw block.

[0009] Furthermore, the lifting support is provided with at least two connectors, and the upper side of the shuttle car is provided with a connecting part that cooperates with the connectors. The lower end of the connector is detachably connected to the connecting part of the shuttle car.

[0010] Furthermore, each connecting component includes a connecting bolt, the stud of the connecting bolt moves downward through the stud through hole on the lifting bracket, the outer diameter of the bolt head of the connecting bolt is larger than the inner diameter of the stud through hole, and the connecting part on the upper side of the shuttle car is a threaded connecting hole that mates with the stud of the connecting bolt.

[0011] Beneficial effects: The rescue structure of the faulty shuttle of this utility model uses a rescue tool to lift the faulty shuttle to the upper end of the running track, thereby avoiding the huge obstruction between the faulty shuttle and the running track after the faulty shuttle stops running. Then, a non-faulty shuttle is designated to travel below the faulty shuttle, and the non-faulty shuttle can smoothly transport the faulty shuttle on the running track to the maintenance point for repair.

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] As attached Figure 1As shown, a rescue structure for a malfunctioning shuttle includes a travel track 1, a shuttle 3, and a rescue tool 5. The shuttle 3 is located inside the travel track 1. The rescue tool 5 can be detachably installed at the upper end of any local position on the travel track 1. The rescue tool 5 installed at the upper end of any local position on the travel track 1 can be detachably connected to the upper end of the shuttle 3 within the travel track 1 at that location. The rescue tool 5 can lift and release the shuttle 3 connected below. When the shuttle 3 malfunctions while traveling on the travel track 1, the shuttle 3 remains stationary on the travel track 1. The rescue tool 5 can lift the stationary shuttle 3 on the travel track 1 until it is detached from the travel track 1. Let the height of the shuttle 3 in its non-lifted state be H. The rescue tool 5 can lift the shuttle 3 connected below by at least H height.

[0017] The travel track 1 is a double track, which includes a first track 2 and a second track 6 that are symmetrical on the left and right. The shuttle car 3 rolls and is guided between the first track 2 and the second track 6. The upper ends of the sides of the first track 2 and the second track 6 that are far apart from each other are bent outward to form an installation platform 7. The rescue tools 5 are mounted on the upper ends of the first track 2 and the second track 6, that is, the two rescue tools 5 are mounted on the two installation platforms 7 on both sides.

[0018] like Figure 2 As shown, the rescue tool 5 includes a lifting bracket 8, a claw block 9, and a climbing rod 10. The lifting bracket 8 is vertically mounted above the first track 2 and the second track 6, and at least two connecting parts 11 are provided on the lifting bracket 8. Vertical climbing rods 10 are movably installed at both ends of each lifting bracket 8. The lifting bracket 8 can be adjusted up and down relative to the two climbing rods 10. At least one of the two climbing rods 10 is a threaded rod. The climbing rod 10 with external threads is threadedly engaged with the threaded hole on the lifting bracket 8. The lower end of each climbing rod 10 is connected to a claw block 9. The upper end of the claw block 9 is provided with a rotating connecting part, the lower end of the claw block 9 is a claw, and the rotating connecting part is a bearing. The lower end of the climbing rod 10 is rotatably connected to the claw block 9. The two claw blocks 9 can be fixedly locked on the upper side of the first track 2 and the second track 6 respectively. That is, the claws of each claw block 9 are locked on both sides of the mounting platform 7 at the upper end of the first track 2 and the second track 6 along the length direction. Several fasteners lock each claw block 9 on the mounting platform 7 at the upper end of the first track 2 and the second track 6 through the locking holes on the claws of each claw block 9.

[0019] In this utility model, the two climbing rods 10 connected to both ends of the lifting bracket 8 are threaded rods, and the lifting bracket 8 is provided with two connecting parts 11. The upper end of the shuttle car 3 is provided with two lifting brackets 8 that are perpendicular to the travel track 1, and the upper side of the shuttle car 3 is provided with a connecting part 18 that cooperates with the connecting parts 11. The lower end of the connecting part 11 is detachably connected to the connecting part 18 of the shuttle car 3.

[0020] After the maintenance personnel receive the rescue tool 5, they first use the claws of the two claw blocks 9 to clamp the two claw blocks 9 onto both sides of the mounting platform 7 at the upper end of the first track 2 and the second track 6 along the length direction. Then, they use fasteners to lock the two claw blocks 9 onto the mounting platform 7 at the upper end of the travel track 1 where the shuttle car 3 is located. Then, they thread the two climbing rods 10 into the through threaded holes at both ends of a lifting bracket 8. Then, they rotate the lower end of each climbing rod 10 onto the rotating connection part at the upper end of each claw block 9. According to the above steps, several sets of rescue tools 5 are assembled, and several sets of rescue tools 5 are arranged side by side along the length direction of the travel track 1 on the mounting platform 7 at the upper end of the travel track 1 within the range of the shuttle car 3. In the embodiment of this utility model, there are two sets of rescue tools 5.

[0021] like Figure 2 As shown, after the lower ends of each connector 11 are connected to the connecting part 18 on the upper side of the shuttle car 3, the maintenance personnel use a rotary tool to simultaneously rotate the torsion part of the upper end of the two climbing rods 10 connected to both ends of each lifting bracket 8, so that the two climbing rods 10 rotate around their own axis at the same time. The torsion part is generally a cross or slotted groove. As the two climbing rods 10 rotate, the external threads on the two climbing rods 10 engage with the through threaded holes at both ends of the lifting bracket 8, so that the two lifting brackets 8 climb vertically upward relative to the travel track 1. Under the combined action of each connector 11, the shuttle car 3 moves vertically upward relative to the travel track 1 until the shuttle car 3 is raised to a height H under the combined action of each connector 11, and the shuttle car 3 is higher than the upper end of the travel track 1.

[0022] like Figure 3 As shown, the connector 11 includes a connecting bolt 16, the stud of the connecting bolt 16 moves downward through the stud through hole on the lifting bracket 8, the outer diameter of the bolt head of the connecting bolt 16 is larger than the inner diameter of the stud through hole, and the connecting part 18 on the upper side of the shuttle car 3 is a threaded connecting hole that mates with the stud of the connecting bolt 16.

[0023] The working process of the rescue structure of the fault shuttle vehicle of this utility model is as follows:

[0024] When a shuttle 3 carrying goods malfunctions while traveling on track 1, it cannot continue operating normally and becomes stationary on track 1. This shuttle is referred to as the malfunctioning shuttle. After the malfunction, power is supplied to the malfunctioning shuttle by connecting to an external power source. This lowers the malfunctioning shuttle's lifting platform below the top of the first track 2 and the second track 6, thus allowing the pallet carrying the goods, originally located on the malfunctioning shuttle's lifting platform, to be placed on the first track 2 and the second track 6. At this point, the faulty shuttle is located under the pallet carrying the goods. Then, a new shuttle 3 is placed on the travel track 1. This new shuttle is called the transport shuttle. The transport shuttle moves towards the faulty shuttle and eventually pushes the faulty shuttle out of the area under the pallet carrying the goods. Then, the lifting plate of the transport shuttle lifts the pallet carrying the goods on the travel track 1 upward, thereby separating the pallet carrying the goods on the travel track 1 from the travel track 1 and transporting it to the designated position by the transport shuttle.

[0025] Then, a new shuttle 3 is designated on the travel track 1 and designated as the rescue shuttle. After the rescue shuttle travels along the travel track 1 to the tool retrieval point, the maintenance personnel place the rescue tool 5 on the lifting plate of the rescue shuttle. Then, the maintenance personnel control the rescue shuttle to travel along the travel track 1 along the path close to the malfunctioning shuttle 3. When the rescue shuttle is near the malfunctioning shuttle 3, the maintenance personnel install the rescue tool 5 placed on the rescue shuttle 3 at the top of the first track 2 and the second track 6 of the travel track 1.

[0026] Then, the maintenance personnel threaded the connectors 11 on the two lifting brackets 8 in the rescue tool 5 to the connecting parts 18 on the faulty shuttle. After the lower ends of each connector 11 are connected to the connecting parts 18 on the upper side of the faulty shuttle, the maintenance personnel simultaneously rotated the torsion parts on the upper ends of the two climbing rods 10 connected to both ends of each lifting bracket 8 using a rotating tool. This caused the two climbing rods 10 to rotate around their own axes at the same time. The torsion parts are generally cross or slotted. As the two climbing rods 10 rotate, the external threads on the two climbing rods 10 engage with the through threaded holes at both ends of the lifting bracket 8, thereby causing the two lifting brackets 8 to climb vertically upward relative to the travel track 1. During this process, each connector 11 simultaneously exerts an upward lifting force on the faulty shuttle. Under the combined action of each connector 11, the faulty shuttle moves vertically upward relative to the travel track 1 until the faulty shuttle is raised to a height H under the combined action of each connector 11, and the faulty shuttle is higher than the upper end of the travel track 1.

[0027] At this point, the vertical distance between the malfunctioning shuttle and the travel track 1 is sufficient to allow the rescue shuttle to travel on the travel track 1 without obstruction. Then, control the rescue shuttle to move it below the malfunctioning shuttle, and then disengage the connector 11 in the rescue tool 5 from the connector 18 on the malfunctioning shuttle, thereby separating the malfunctioning shuttle from the rescue tool 5. At this point, the malfunctioning shuttle is located on the lifting plate of the rescue shuttle. Then, disassemble the rescue tool 5 so that it cannot obstruct the process of the rescue shuttle moving the malfunctioning shuttle. Finally, control the rescue shuttle to move the malfunctioning shuttle to the repair shop along the travel track 1.

[0028] The above are the preferred embodiments described in this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
