Description

Technical Field

[0001] The present invention relates to the technical field of logistics transportation, and particularly to an intelligent logistics shuttle. Background Art

[0002] In recent years, with the rapid development of the logistics industry, various novel logistics transportation methods and equipment have emerged one after another. The intelligent transportation express line is a brand-new logistics transportation method. Generally speaking, the intelligent transportation express line is to erect a transportation network in the low altitude. The transportation network is usually laid by steel cables or steel rails. A large number of shuttles are installed on the transportation network, and the shuttles are attached with transportation items or logistics boxes. These shuttles are equipped with driving and walking devices by themselves, so that the shuttles can walk along the transportation network.

[0003] Compared with the traditional cable car transportation, the intelligent transportation express line has the advantages of a wide regional scope (it can achieve cross-provincial and cross-regional transportation), high speed (the speed of the shuttle can reach more than 60 km / h), and low energy consumption. In order to meet the above requirements, on the one hand, the shuttle should have good stability and shock absorption performance during transportation, and on the other hand, the loading and unloading method of the logistics box on the shuttle should be as fast and efficient as possible. However, the existing cable cars cannot meet the above requirements. Therefore, it has become an urgent problem to provide a new type of intelligent transportation express line shuttle. Summary of the Invention

[0004] The purpose of the present invention is to provide an intelligent logistics shuttle to solve the technical problem that related equipment such as cable cars in the prior art cannot meet the transportation requirements of the intelligent transportation express line.

[0005] To achieve the above purpose, the present invention provides an intelligent logistics shuttle, adopting the following technical solutions:

[0006] An intelligent logistics shuttle includes a walking drive mechanism, a connecting frame, a control device, and a logistics box. The connecting frame is connected to the walking drive mechanism through a shock absorption mechanism, and the shock absorption mechanism is used to buffer the vibration of the connecting frame;

[0007] The logistics box is detachably assembled on the connecting frame through a hanging box clamp lock. The hanging box clamp lock includes a lock groove assembly and a hanging beam assembly. One of the lock groove assembly and the hanging beam assembly is installed on the connecting frame, and the other is installed on the logistics box. A guiding card slot for the guiding insertion of the hanging beam assembly is provided on the lock groove assembly, and the logistics box is fixed to the connecting frame through the insertion and assembly of the lock groove assembly and the hanging beam assembly;

[0008] The hanging box clamp lock further includes a lock pin structure. The lock pin structure includes a plug pin and a lock hole. One of the plug pin and the lock hole is provided on the lock groove assembly, and the other is provided on the hanging beam assembly. When the hanging beam assembly is inserted and assembled on the lock groove assembly, the plug pin pops out and inserts into the lock hole to limit the relative sliding of the lock groove assembly and the hanging beam assembly.

[0009] Furthermore, the hanging box clamp lock further includes a first monitoring device for monitoring whether the hanging beam body is inserted in place. The first monitoring device includes a second switch and a sensing member. One of the second switch and the sensing member is arranged on the lock groove assembly, and the other is arranged on the hanging beam assembly. The second switch is electrically connected to the control device.

[0010] Furthermore, the lock pin structure is a first switch, and a second monitoring device for performing a closed-loop detection on the first switch is connected to the first switch. Both the first switch and the second monitoring device are electrically connected to the control device.

[0011] Furthermore, the shock absorption mechanism includes a shock absorption seat connected to the traveling drive mechanism. The shock absorption seat is slidably assembled on the connecting frame through a guide rod, and a shock absorption spring is sleeved on the guide rod between the shock absorption seat and the connecting frame.

[0012] Furthermore, the shock absorption seat is rotatably assembled with the traveling drive mechanism through a rotating shaft.

[0013] Furthermore, the control device is detachably assembled in the connecting frame. The shock absorption mechanism is arranged between the connecting frame and the control device, and an avoidance groove for accommodating the shock absorption mechanism is arranged on the control device.

[0014] Furthermore, a plurality of heat dissipation holes are arranged on the side wall of the avoidance groove, and a water blocking eyebrow plate covering each heat dissipation hole inside is further arranged on the side wall of the avoidance groove.

[0015] Furthermore, the control device includes a control box body and a control box cover. The control box cover is hermetically assembled on the control box body through a waterproof structure. The waterproof structure includes a flange and a sealing ring. One of the flange and the sealing ring is arranged at the opening edge position of the control box body, and the other is arranged at the corresponding edge position of the control box cover. A sealing slot for inserting the flange is arranged on the sealing ring.

[0016] Furthermore, the bolt is arranged on the inner side wall of the guiding card slot, and a first guiding surface is arranged on the hanging beam assembly. The first guiding surface is used for ejecting the bolt out of the guiding card slot during the process of inserting the hanging beam assembly into the guiding card slot.

[0017] Further, a first stop portion is provided on the inner side wall of the guiding card slot. The hanging beam assembly includes a hanging beam main body, and a second stop portion for mutually stopping with the first stop portion to realize the insertion and assembly of the hanging beam assembly and the lock slot assembly is provided on the hanging beam main body. A positioning structure is provided on the first stop portion and the second stop portion. The positioning structure includes a positioning member and a positioning slot. One of the positioning member and the positioning slot is provided on the first stop portion, and the other is provided on the second stop portion. The positioning member is inserted into the positioning slot when the hanging beam assembly is inserted and assembled on the lock slot assembly. The beneficial effects are as follows: The setting of the positioning structure enhances the positioning accuracy of the hanging beam assembly and the lock slot assembly on the one hand, ensuring the accurate positioning of the hanging beam assembly and the lock slot assembly; on the other hand, the positioning structure also has the function of self-returning. Since the positioning member and the positioning slot are in an inserted and mated relationship, when there is a small error in the insertion position of the hanging beam assembly and the lock slot assembly, due to the action of gravity, the positioning member and the positioning slot will be inserted and docked automatically, thereby realizing the correction of the error between the hanging beam assembly and the lock slot assembly, ensuring the accurate insertion and assembly of the hanging beam assembly and the lock slot assembly, and ensuring that the relative positioning position remains fixed during operation, avoiding the hanging beam main body pressing the bolt during operation and preventing the bolt from retracting and unlocking.

[0018] Further, at least one end of the first stop portion is provided with a second guiding surface for guiding the second stop portion to the corresponding contact surface of the first stop portion when the hanging beam assembly and the lock slot assembly are inserted and assembled.

[0019] Further, at least one end of the first stop portion is provided with a third guiding surface for enlarging the port of the guiding card slot to guide the hanging beam assembly to insert into the guiding card slot.

[0020] Further, at least one end of the hanging beam main body is provided with a fourth guiding surface for guiding the hanging beam main body to insert into the guiding card slot.

[0021] Compared with the prior art, the beneficial effects of the intelligent logistics shuttle of the embodiment of the present invention are as follows: By adopting the intelligent logistics shuttle of the present invention, a shock absorption mechanism is provided on the shuttle. Since the traveling driving mechanism is directly connected to the steel cable or the steel rail during actual use, and the control device and the logistics box are suspended below the traveling driving mechanism through the connecting frame, when the traveling driving mechanism vibrates violently, the shock absorption mechanism provided between the connecting frame and the traveling driving mechanism will reduce the vibration of the control device, the connecting frame and the logistics box, thereby ensuring the smoothness of transportation; in addition, the setting of the hanging box clamp realizes the automatic loading and unloading between the logistics box and the connecting frame, saves the loading and unloading time, and improves the transportation efficiency of the shuttle.

Specific implementation mode

[0037] The following combines the accompanying drawings and embodiments to further describe in detail the specific implementation mode of the present invention. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0038] As Figures 1 to 14 shown, a preferred embodiment of a smart logistics shuttle of the embodiment of the present invention is provided. The smart logistics shuttle includes a walking drive mechanism 1, a connecting frame 2, a control device 3, and a logistics box 4. The connecting frame 2 is connected to the walking drive mechanism 1 through a shock absorption mechanism 5. The shock absorption mechanism 5 is used to apply a reset force to the connecting frame 2 to buffer the vibration of the connecting frame 2. The logistics box 4 is detachably assembled on the connecting frame 2 through a hanging box clamp lock. The hanging box clamp lock includes a lock slot assembly and a hanging beam assembly. One of the lock slot assembly and the hanging beam assembly is installed on the connecting frame 2, and the other is installed on the logistics box 4. The lock slot assembly is provided with a guide card slot 606 for guiding and inserting the hanging beam assembly. The logistics box 4 is fixed to the connecting frame 2 through the insertion and assembly of the lock slot assembly and the hanging beam assembly. The hanging box clamp lock further includes a lock pin structure 602. The lock pin structure 602 includes a plug pin 607 and a lock hole 618. One of the plug pin 607 and the lock hole 618 is arranged on the lock slot assembly, and the other is arranged on the hanging beam assembly. When the hanging beam assembly is inserted and assembled on the lock slot assembly, the plug pin 607 pops out and inserts into the lock hole 618 to limit the relative sliding of the lock slot assembly and the hanging beam assembly. The hanging box clamp lock further includes a first monitoring device for monitoring whether the hanging beam main body 614 is inserted and assembled in place.

[0039] Specifically, in this embodiment, the walking driving mechanism 1 is installed on the erected low-altitude transportation network. The walking driving mechanism 1 includes a driving wheel 101 and a driving motor for driving the driving wheel 101 to rotate. The driving wheel 101 is in direct contact with the steel cable or steel rail of the transportation network, and the shuttle can walk by itself through the rotation of the driving wheel 101. Since the walking driving mechanism 1 of the shuttle is a mature existing technology, and the walking driving mechanism 1 of the shuttle is also disclosed in the patent document of the Chinese invention patent application with the application publication number CN107839697A, the name of the shuttle driving mechanism, the shuttle and the cableway system, therefore, the specific structure of the walking driving mechanism 1 will not be described in detail in this embodiment. A suspension arm is fixed on the walking driving mechanism 1 in this embodiment, and the connecting frame 2 is connected to the bottom of the suspension arm. Specifically, a shock absorption mechanism 5 is installed on the connecting frame 2, and the shock absorption mechanism 5 is rotationally assembled with the suspension arm. In this embodiment, the connecting frame 2 is a U-shaped frame with the opening facing downwards, the control device 3 is installed inside the connecting frame 2, a lock groove assembly is installed at the U-shaped opening position of the connecting frame 2, and a hanging beam assembly is installed on the logistics box 4. The logistics box 4 in this embodiment can be detachably installed at the bottom of the connecting frame 2 through the hanging box clamp lock 6. The logistics box 4 in this embodiment is used to store the transported goods.

[0040] As Figure 3 shown, the shock absorption mechanism 5 in this embodiment includes a shock absorption seat 502, and the shock absorption seat 502 is a rectangular flat plate. Two vertical plates are integrally provided on the shock absorption seat 502. The two vertical plates are arranged at the middle position of the shock absorption seat 502 and are parallel and spaced apart. A rotating shaft 503 is rotationally assembled between the two vertical plates. Specifically, in this embodiment, both ends of the rotating shaft 503 are rotationally assembled on the corresponding vertical plates through bearings. The rotating shaft 503 in this embodiment is used to be rotationally assembled with the suspension arm. It should be noted that a connecting hole for the rotating shaft 503 to pass through is provided at the bottom of the suspension arm in this embodiment. The suspension arm is rotationally assembled with the rotating shaft 503, and the rotating shaft 503 is rotationally assembled with the shock absorption seat 502. This design makes the shock absorption seat 502 not swing with the swing of the suspension arm, thereby ensuring the stability of the shape of the logistics box 4. Since the shock absorption mechanism 5 is installed inside the connecting frame 2 in this embodiment, in order to facilitate the connection between the suspension arm and the rotating shaft 503, a rectangular hole for the bottom of the suspension arm to pass through is provided on the connecting frame 2 in this embodiment.

[0041] In this embodiment, a guiding rod 504 is threadedly installed at each of the four corner positions of the shock absorber seat 502. The end of the guiding rod 504 for connecting with the shock absorber seat 502 is provided with an external thread, and a threaded hole is correspondingly provided at each of the four corner positions of the shock absorber seat 502. In this embodiment, the four guiding rods 504 are arranged in parallel and are all guidingly and slidably assembled at corresponding positions of the connecting frame 2. The connecting frame 2 is provided with shock absorption mounting holes 501 for the guiding rods 504 to pass through. In order to enhance the shock absorption strength, in this embodiment, a shock absorption sleeve 506 is sleeved on the outer peripheral side of each guiding rod 504, and each shock absorption sleeve 506 is arranged in the corresponding shock absorption mounting hole 501. In this embodiment, the shock absorption sleeve 506 is provided with an annular protrusion on the side facing the shock absorber seat 502, and the annular protrusion can be mutually blocked with the edge of the shock absorption mounting hole 501, so as to prevent the shock absorption sleeve 506 from coming out of the shock absorption mounting hole 501. In this embodiment, a shock absorption spring 505 is also sleeved on each guiding rod 504. Specifically, the shock absorption spring 505 is arranged at the position between the shock absorption sleeve 506 and the shock absorber seat 502, and the shock absorption spring 505 is clamped between the shock absorber seat 502 and the annular protrusion of the shock absorption sleeve 506. In order to avoid the problem that the top of the guiding rod 504 comes out of the shock absorption sleeve 506, in this embodiment, a stop head is arranged at the top end of each guiding rod 504, and the structure and function of the stop head are similar to those of a bolt head. In this embodiment, the shock absorption sleeve 506 is fixed to the connecting frame 2 by screws. Specifically, the annular protrusion is provided with fixing holes for the screws to pass through, and the fixing holes are threaded holes. As Figure 2 shown, the annular protrusion is square, and a fixing hole is arranged at each of the four corner positions of the annular protrusion.

[0042] In this embodiment, the control device 3 is a cloud technology network control system, and in other embodiments, it can also be a common controller or a PLC control system. The controller of the shuttle is also disclosed in the Chinese utility model patent with the authorization announcement number CN207264125U and the name of the shuttle and its control device 3. In this embodiment, the specific structural components of the control device 3 will not be described in detail. In this embodiment, the control device 3 includes a control box, and the relevant structural components of the control device 3 are installed in the control box. The control box includes a control box body 301 and a control box cover 302. As Figure 10 shown, the control box is cuboid-shaped, and open structures are arranged on the front and back sides of the control box, and the control box cover 302 can be detachably installed at both open structures. In order to enhance the sealing performance between the control box cover 302 and the control box body 301, in this embodiment, a waterproof structure is arranged on the control box cover 302 and the control box body 301. The waterproof structure includes a flange 307 and a sealing ring 306. One of the flange 307 and the sealing ring 306 is arranged at the opening edge position of the control box body 301, and the other is arranged at the corresponding edge position of the control box cover 302. The sealing ring 306 is provided with a sealing slot for the flange 307 to be inserted into. Specifically, as Figure 11As shown in the figure, in this embodiment, the flanging 307 is arranged at the opening edge position of the control box body 301. The flanging 307 is arranged in a circle along the opening edge. The sealing ring 306 is arranged at a position close to the edge of the control box cover 302, and the sealing ring 306 is also correspondingly arranged in a circle along the edge of the box cover. When the control box cover 302 is covered on the opening structure of the control box body 301, the flanging 307 will be correspondingly inserted into the sealing slot on the sealing ring 306, and the sealing performance of the butt joint is ensured through the extrusion contact between the sealing ring 306 and the flanging 307. In this embodiment, the sealing ring 306 is a rubber ring.

[0043] Since the shock absorption mechanism 5 is arranged inside the connecting frame 2 in this embodiment, in order to avoid the problem of interference between the shock absorption mechanism 5 and the control box body 301, a relief groove 303 is arranged on the control box body 301 of this embodiment. The relief groove 303 is a rectangular groove and is arranged at the middle position on the top of the control box body 301. In this embodiment, the relief groove 303 can be inserted by the shock absorption mechanism 5 and extends along the left-right direction.

[0044] In order to improve the heat dissipation performance of the control device 3, in this embodiment, heat dissipation hole groups are arranged on the two side walls of the relief groove 303. The heat dissipation hole groups include a plurality of heat dissipation holes 304 arranged in a matrix. In this embodiment, a total of four heat dissipation hole groups are arranged, and two heat dissipation hole groups are arranged on each of the two side walls of the relief groove 303. In order to avoid rainwater flowing into the control device 3 from the heat dissipation holes 304, in this embodiment, water retaining eyebrow plates 305 are arranged at the edge positions of each heat dissipation hole group. The water retaining eyebrow plate 305 is a U-shaped plate. In this embodiment, the control device 3 can be detachably installed in the connecting frame 2 by screws, and the structure after the control device 3 and the connecting frame 2 are installed is as Figure 12 shown. The installation positions of the screws are located on the left and right side surfaces of the control device 3. In order to further enhance the heat dissipation performance, in this embodiment, heat dissipation holes are also arranged on the connecting frame 2, and the heat dissipation holes on the connecting frame 2 are arranged at positions opposite to the ports of the relief groove 303. When the shuttle moves at high speed, the air flow velocity outside the shuttle is relatively fast and the pressure is relatively small, thus forming a siphon effect around the shuttle. The heat inside the control device will be sucked out of the control device under the siphon action and flow out from the heat dissipation hole groups and the heat dissipation holes on the connecting frame, thereby improving the heat dissipation performance of the control device.

[0045] In this embodiment, the hanging box clamp lock 6 can be detachably installed at the bottom of the connecting frame 2. The hanging box clamp lock 6 includes a lock groove assembly and a hanging beam assembly. As Figure 6 and Figure 7As shown, the lock groove assembly includes two parallel slot frames 601, and both of the two slot frames 601 are installed at the U-shaped opening position of the connecting frame 2. Specifically, in this embodiment, the ends of the two slot frames 601 are fixed to the inner wall of the connecting frame 2 through the second bolts 605. After both of the two slot frames 601 are fixed to the connecting frame 2, the gap between the two slot frames 601 constitutes the guiding slot 606 in this embodiment. A first stop portion 609 is arranged in the guiding slot 606. In this embodiment, the first stop portion 609 is a support frame, and the support frame is a strip-shaped profile. Specifically, in this embodiment, one support frame is installed on each of the two slot frames 601, and the two support frames are arranged oppositely and are both located between the two slot frames 601. In this embodiment, both of the two support frames are detachably fixed to the corresponding slot frames 601 through the first bolts 610, and a plurality of threaded holes for the first bolts 610 to penetrate are arranged on both the slot frames 601 and the support frames. The arrangement of the two support frames makes the cross-sectional shape of the guiding slot 606 be T-shaped, specifically as Figure 5 shown. Since the hanging beam main body 614 is to be inserted into the guiding slot 606, in this embodiment, an opening for the hanging beam main body 614 to pass through is arranged at the end of the connecting frame 2. Specifically, the opening is arranged at the position between the two slot frames 601.

[0046] In this embodiment, the lock pin structure 602 is a first switch, and the first switch is specifically an electromagnetic switch. There are two first switches, and both of the two first switches are respectively fixed to the corresponding slot frames 601 through screws. First grooves 612 for fixing the first switches are arranged on the outer sides of the two slot frames 601. In this embodiment, the first switch includes a bolt 607, and insertion holes for the bolt 607 to insert are arranged at the bottom positions of the respective first grooves 612. After the first switch is fixed in the corresponding first groove 612, the bolt 607 of the first switch can extend into the interior of the guiding slot 606 through the insertion hole. It should be noted that in this embodiment, the support frame is installed below the inner side of the slot frame 601, and the socket on the slot frame 601 is arranged above the inner side of the slot frame 601, that is, the insertion hole and the support frame are arranged in a staggered manner. In this embodiment, the two first grooves 612 are respectively arranged at the middle positions of the corresponding slot frames 601. Correspondingly, the two insertion holes are also respectively arranged at the middle positions of the corresponding slot frames 601. Since the first switch is a mature prior art, the specific structure of the first switch will not be introduced in detail in this embodiment.

[0047] The first monitoring device includes a second switch 603 and a sensing member 617. The second switch 603 is specifically a Hall switch, and the sensing member is specifically a magnet. In this embodiment, there are two second switches 603, and the two second switches 603 are respectively installed on the corresponding slot brackets 601. Specifically, a second groove 613 is provided on the inner side wall of each of the two slot brackets 601. The second groove 613 is a rectangular groove, and the second groove 613 is also provided above the inner side of the slot bracket 601. In this embodiment, the two second grooves 613 are arranged in central symmetry. In this embodiment, the two second switches 603 are both fixed in the corresponding second grooves 613 by screws. In this embodiment, there are two corresponding sensing members 617, and the two sensing members 617 are both fixed on the hanging beam assembly. Specifically, the two sensing members 617 are both provided on the second stopping portion 615. After the hanging beam main body 614 is inserted into the guiding card slot 606, the two sensing members 617 are respectively opposite to one second switch 603. At this time, the second switch 603 becomes effective under the action of the sensing member 617 and sends a first monitoring signal to the control device 3. After receiving the first monitoring signal, the control device 3 determines that the hanging beam main body 614 has been inserted and assembled in place; if the second switch 603 is not opposite to the corresponding sensing member 617, the second switch 603 is not effective at this time, and the control device 3 cannot receive the first monitoring signal, then it is determined that the hanging beam main body 614 is not accurately inserted and assembled in place. At this time, the relative positions of the lock slot assembly and the hanging beam assembly need to be readjusted.

[0048] Since the lock pin structure 602 of this embodiment is a first switch, the plug pin 607 of the first switch may fail to pop out or retract normally during the reciprocating motion. The occurrence of this situation will cause the logistics box 4 to be unable to be fixed normally, but the operator cannot directly observe it. To avoid this situation, in this embodiment, a second monitoring device 604 is installed on each first switch. The second monitoring device 604 is an optocoupler, and the optocoupler is electrically connected to the control device 3. Under normal circumstances, the plug pin 607 of the first switch is inserted into the guiding card slot 606. At this time, the plug pin 607 will not block the optocoupler, and the optocoupler normally transmits the optical signal and sends a second monitoring signal to the control device 3. The control device 3 judges that the plug pin 607 pops out according to the received second monitoring signal; when the plug pin 607 of the first switch fails to pop out normally, the plug pin 607 will block the optocoupler. At this time, the optocoupler cannot normally transmit the optical signal, resulting in the control device 3 being unable to receive the second monitoring signal of the optocoupler, then it is determined that the plug pin 607 fails to pop out normally. The above combination of the first switch and the optocoupler has been disclosed in the Chinese utility model patent with the authorization announcement number CN203572931 and the patent name Detection Feedback Circuit. For the specific working principle of the first switch and the optocoupler, it will not be elaborated in this embodiment.

[0049] The hanging beam assembly of this embodiment includes a hanging beam main body 614, as Figure 8and Figure 9 As shown, the hanging beam main body 614 is a vertical plate fixed on the logistics box 4. The overall shape of the vertical plate is trapezoidal, and the thickness of the vertical plate is less than the distance between the two support frames. A second stop portion 615 is provided on the hanging beam main body 614. The second stop portion 615 is a horizontal plate arranged perpendicular to the vertical plate, and the horizontal plate is integrally provided at the top of the vertical plate. Since the hanging beam main body 614 needs to be inserted into the guiding slot 606, in order to avoid the situation where the insertion pin 607 is blocked by the end face of the second stop portion 615 and cannot be inserted, first guiding surfaces 616 are provided at both ends of the second stop portion 615 in this embodiment. There are a total of four first guiding surfaces 616, and two second guiding surfaces 608 are respectively provided at both ends of the second stop portion 615. The two first guiding surfaces 616 on the same side are symmetric about the hanging beam main body 614. The setting of the four first guiding surfaces 616 makes the second stop portion 615 as a whole hexagonal. When the hanging beam main body 614 is inserted into the guiding slot 606, the first guiding surfaces 616 will push the two insertion pins 607 into the side wall of the guiding slot 606, thereby ensuring that the hanging beam assembly can be completely inserted into the guiding slot 606. In this embodiment, a locking hole 618 for the insertion pin 607 to insert is provided on the second stop portion 615. There are two locking holes 618, and they are symmetrically arranged on both sides of the second stop portion 615. In this embodiment, both of the two locking holes 618 are provided at the middle position of the second stop portion 615.

[0050] In order to facilitate guiding the second stop portion 615 to the top surface (i.e., the corresponding contact surface) of the first stop portion 609, a second guiding surface 608 is provided on the first stop portion 609 in this embodiment. The second guiding surface 608 is used to guide the second stop portion 615 to the corresponding side surface of the first stop portion 609 to achieve the mutual stop between the first stop portion 609 and the second stop portion 615. Specifically, in this embodiment, a second guiding surface 608 is provided at both ends of each support frame, and each second guiding surface 608 is an inclined surface.

[0051] In order to facilitate the insertion and assembly of the hanging beam assembly and the lock groove assembly, third guiding surfaces 620 are also provided at both ends of the first stop portion, and fourth guiding surfaces 621 are also provided at both ends of the hanging beam main body in this embodiment. In this embodiment, the third guiding surface 620 is an inclined surface. The two third guiding surfaces 620 at the same end of the two first stop portions are arranged oppositely, and the port of the guiding slot is made open. The setting of the third guiding surface 620 increases the port size of the guiding slot and facilitates the accurate insertion of the hanging beam main body into the guiding slot. In this embodiment, the fourth guiding surface 621 is also an inclined surface. Two fourth guiding surfaces 621 are provided at both ends of the hanging beam main body. As Figure 9As shown, the two fourth guiding surfaces 621 at the same end of the hanging beam body are symmetrically arranged on the opposite side surfaces. On one hand, the two fourth guiding surfaces 621 at the same end make the end of the hanging beam body as a whole in a wedge shape, which facilitates the accurate insertion of the hanging beam body into the guiding card slot. On the other hand, the two fourth guiding surfaces 621 at the same end also make the edge of the hanging beam body thinner, and such a design plays a role of guiding and correcting, further facilitating the insertion of the hanging beam body into the guiding card slot.

[0052] In order to further ensure the accuracy of the positioning of the hanging beam assembly and the lock slot assembly, in this embodiment, a positioning structure is further provided on the first stop portion 609 and the second stop portion 615. The positioning structure includes a positioning member 619 and a positioning slot 611. One of the positioning member 619 and the positioning slot 611 is arranged on the first stop portion 609, and the other is arranged on the second stop portion 615. When the hanging beam assembly is inserted and assembled on the lock slot assembly, the positioning member 619 is inserted into the positioning slot 611. Specifically, in this embodiment, the positioning slot 611 is arranged at the middle position of the first stop portion 609, and four positioning slots 611 are arranged on the top surfaces of the two first stop portions 609. Correspondingly, in this embodiment, the positioning members 619 are all rotatably assembled on the bottom surface of the second stop portion 615. A total of eight positioning members 619 are installed on the second stop portion 615, four of which are located on one side of the hanging beam body 614, and the other four are located on the other side of the hanging beam body 614. In this embodiment, each positioning member 619 is a rolling column, and a limiting card slot is arranged at the bottom of the second stop portion 615. Each positioning member 619 is rotatably assembled in the corresponding limiting card slot and partially extends out of the slot opening of the limiting card slot. After the hanging beam assembly is inserted into the lock slot assembly, the part of each positioning member 619 extending out of the limiting card slot will be horizontally inserted into the corresponding positioning slot 611, thereby realizing the precise insertion and fixing of the hanging beam assembly and the lock slot assembly. In this embodiment, the two lock holes 618 are located in the middle of each positioning member 619, and each positioning member 619 is located between the two sensing members 617. It should be noted that in other embodiments, the positioning member is a fixed member, that is, each positioning member can be integrally arranged on the second stop portion, and no rotation occurs between each positioning member and the second stop portion. By providing the positioning member and the positioning slot, when there is a small error in the insertion position of the hanging beam assembly and the lock slot assembly, due to the action of gravity and the guiding action of the contact surface between the positioning member and the positioning slot, the positioning member and the positioning slot will be self-inserted and docked, thereby realizing the correction of the error of the hanging beam assembly and the lock slot assembly, ensuring the precise insertion and assembly of the hanging beam assembly and the lock slot assembly, and ensuring that the relative positioning position remains fixed during operation, avoiding the hanging beam body pressing the bolt during operation. Avoiding that the bolt cannot be retracted, that is, the unlocking action cannot be performed.

[0053] The installation and disassembly working process of the logistics box 4 of the present invention is as follows: during installation, first load the goods to be transported into the logistics box 4, and then insert the hanging beam body 614 and the second stop portion 615 into the guiding card slot 606, asFigure 13 As shown, during the insertion process, the second guiding surface 608 on the first stop portion 609 will guide the second stop portion 615 to the top surface of the first stop portion 609, while the hanging beam body 614 slides in the gap between the two support frames. When the first guiding surface 616 slides to the position of the bolt 607, the first guiding surface 616 will push the corresponding bolt 607 into the groove wall of the guiding card slot 606, and then the hanging beam assembly continues to slide along the guiding card slot 606. When the two lock holes 618 move to the position corresponding to the bolt 607, the bolt 607 will pop out automatically and insert into the corresponding lock hole 618, thereby realizing the limit fixation of the sliding direction of the lock slot assembly and the hanging beam assembly. The mutual fitting of the first stop portion 609 and the second stop portion 615 further restricts the relative rotation of the lock slot assembly and the hanging beam assembly, thereby realizing the fixed locking of the connecting frame 2 and the logistics box 4. It should be noted that when the two bolts 607 are inserted into the corresponding lock holes 618, the positioning members 619 on the second stop portion 615 will correspondingly insert into the respective positioning slots 611. In addition, the two sensing members 617 will also slide to the positions corresponding to the corresponding second switches 603. The two second switches 603 will also take effect under the action of the corresponding sensing members 617 and send a first monitoring signal to the control device 3. After receiving the first monitoring signal, the control device 3 will judge that the hanging beam assembly has slid in place, as Figure 14 shown. In addition, since the two bolts 607 are inserted into the corresponding lock holes 618, the optical couplers on the two first switches will not be blocked. At this time, the control device 3 will receive the second monitoring signal emitted by the optical coupler and determine that the two bolts 607 pop out normally, that is, normal locking.

[0054] When it is necessary to disassemble the logistics box 4, the control device 3 is used to drive the two first switches. At this time, the two bolts 607 will retract into the side wall of the guiding card slot 606. Due to the retraction of the bolts 607, the two optical couplers will be blocked. At this time, the control device 3 will not receive the second monitoring signal. The control device 3 will judge that the two bolts 607 have been withdrawn from the corresponding lock holes 618, and the second suspension device can slide out from the first suspension device.

[0055] During the transportation of the shuttle, due to the unevenness of the steel cable or the steel rail, the walking drive mechanism 1 will shake, which will drive the suspension arm to shake. This kind of shake can be further divided into swing and up-and-down vibration. When swinging, since the suspension arm is rotationally assembled on the shock absorption mechanism 5, the suspension arm itself swings, while the logistics box 4 and the connecting frame 2 will be in a relatively stable state under the action of gravity, thus ensuring the stability of transportation. In addition, when vibrating up and down, the suspension arm will directly act on the shock absorption mechanism 5, and the force transmitted to the rotating shaft 503 and the fixed seat will be slowed down by the shock absorption spring 505, thereby reducing the amplitude of the up-and-down vibration of the logistics box 4 and further ensuring the stability of transportation.

[0056] In summary, the embodiment of the present invention provides a smart logistics shuttle, which is provided with a shock absorption mechanism 5. When the walking drive mechanism 1 vibrates violently, the shock absorption mechanism 5 arranged between the connecting frame 2 and the walking drive mechanism 1 will reduce the vibration of the control device 3, the connecting frame 2 and the logistics box 4, thereby ensuring the smoothness of transportation; in addition, the setting of the hanging box clamp lock realizes the fast and automatic loading and unloading between the logistics box 4 and the connecting frame 2, saves the loading and unloading time, and improves the transportation efficiency of the shuttle to a certain extent.

[0057] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and substitutions can be made, and these improvements and substitutions should also be regarded as the protection scope of the present invention.
