Description

Technical Field

[0001] The present invention relates to the technical field of loading and unloading equipment, and in particular to automatic loading and unloading equipment for intelligent logistics transportation. Background Art

[0002] Intelligent logistics is the use of integrated intelligent technology to enable the logistics system to imitate human intelligence and have the ability to think, perceive, learn, reason and judge, and solve certain problems in logistics on its own.

[0003] Intelligent logistics transportation has been applied to the transportation of goods in various occasions. Intelligent material transportation requires the cooperation of loading and unloading equipment. However, for the transportation of high-pressure tank dangerous goods such as gas tanks, it is still necessary to manually control the loading and unloading truck to move the high-pressure tank. Before transportation, the transporters need to move the high-pressure tanks one by one to the loading and unloading truck. When the loading and unloading truck transports the high-pressure tanks to the carriage of the transport truck, the transporters are also required to move the high-pressure tanks one by one to the inside of the carriage for stacking. During the stacking process, in order to avoid collisions between high-pressure tanks due to vibration during transportation, the stacking distance needs to be controlled. Manual control of the stacking distance is often not uniform and the carriage space is limited. It is inevitable that some high-pressure tanks are close to each other (during the vibration of high-pressure tanks that are close to each other, collisions may occur), which poses a safety hazard.

[0004] In addition, as the stacking height of high-pressure tanks gradually increases, the difficulty of stacking also gradually increases. It is easy for the stacked high-pressure tanks to collapse due to improper operation.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "top / bottom" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are 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 position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "mounted / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] Example, see Figures 1 to 7 , an automatic loading and unloading device for intelligent logistics transportation, comprising a conveying vehicle 1, a guide plate 23 is fixedly connected to the top of the conveying vehicle 1, a lifting plate 2 is slidably arranged on the surface of the guide plate 23, the top of the conveying vehicle 1 is connected to the lifting plate 2 through a lifting mechanism, for controlling the lifting and lowering of the lifting plate 2, further, the lifting mechanism comprises a guide rod 13 fixedly connected to the side wall of the lifting plate 2, a guide block 12 slidably connected to the surface of the guide rod 13, and a nut block 26 slidably connected to the top of the conveying vehicle 1, the guide block 12 and the nut block 26 are both provided with two and are arranged oppositely, further, a bidirectional screw is threadedly connected to the inner side of the nut block 26, one end of the bidirectional screw is fixedly connected to a driven gear 27, a lifting motor 11 is installed on the top of the conveying vehicle 1, and an output end of the lifting motor 11 is fixedly connected to a driving gear 28 meshing with the driven gear 27, the bottom end of the guide block 12 and the top end of the nut block 26 are both rotatably provided with a cross-rotating rod 14, and the cross-rotating rods 14 are rotatably connected.

[0033] It should be noted that: when the lifting motor 11 is turned on, the lifting motor 11 drives the driving gear 28 to rotate, and then drives the driven gear 27 meshing with it to rotate. Since the radius of the driving gear 28 is smaller than the radius of the driven gear 27, the driven gear 27 rotates slowly, and then drives the nut blocks 26 on both sides to move slowly along the bidirectional screw, thereby realizing the function of the lifting mechanism driving the lifting plate 2 to slowly lift and lower, which is convenient for controlling the stacking height of the high-pressure tank body.

[0034] A deformable conveyor frame is provided at the top of the conveyor vehicle 1 near the lifting plate 2, and the deformable conveyor frame includes a static conveyor plate 8 fixedly connected to the side wall of the lifting plate 2, and a plurality of dynamic conveyor plates 7 are equidistantly provided one by one above the static conveyor plate 8, and a traction top plate 6 is provided above the dynamic conveyor plate 7, and a transfer deformation main rod 9 and a transfer deformation sub-rod 10 are provided on both sides of the traction top plate 6, the dynamic conveyor plate 7 and the static conveyor plate 8 for joint rotation through a rotating shaft, and further, a recess for accommodating a rotating shaft is provided on the side wall of the transfer deformation sub-rod 10, and the rotating shaft on the side wall of the transfer deformation main rod 9 is longer than the rotating shaft on the side wall of the transfer deformation sub-rod 10, so that the transfer deformation main rod 9 and the transfer deformation sub-rod 10 can overlap;

[0035] Furthermore, a telescopic slot is provided on the side wall of the lifting plate 2 near the top, a push block 24 is slidably provided inside the telescopic slot, one end of the push block 24 is fixedly connected to a push spring 25, and the other end of the push spring 25 is fixedly connected to the inner wall of the telescopic slot;

[0036] Furthermore, a relatively arranged winding opening is opened at the top of the lifting plate 2, and a winding roller 3 is rotatably arranged inside the winding opening. A traction rope 4 is wound around the surface of the winding roller 3, and one end of the traction rope 4 is fixedly connected to the top of the traction top plate 6. A traction motor 5 is installed on the side wall of the lifting plate 2, and the output end of the traction motor 5 is fixedly connected to the winding roller 3 through a connecting shaft.

[0037] It should be noted that: when the traction motor 5 drives the winding roller 3 to rotate in the opposite direction, the traction rope 4 wound on the surface of the winding roller 3 is unfolded, and under the action of the push spring 25, the push block 24 pushes the traction top plate 6 to move, thereby making the transfer deformation main rod 9 and the transfer deformation secondary rod 10 in an inclined state. At this time, under the action of the gravity of the traction top plate 6 and the dynamic conveying plate 7, the inclination of the transfer deformation main rod 9 and the transfer deformation secondary rod 10 gradually increases until the two overlap with each other (when overlapping, the notch on the transfer deformation secondary rod 10 is engaged with the rotating shaft on the transfer deformation main rod 9). During this process, the traction top plate 6 and the dynamic conveying plate 7 are always in a horizontal state.

[0038] After the dynamic conveying plate 7 becomes horizontal, the U-shaped conveying groove 15 inside it is automatically sleeved on the surface of the high-pressure tank body, so as to facilitate automatic picking up of the high-pressure tank body.

[0039] It is worth noting that a counterweight block is provided on the conveying vehicle 1 to increase the weight of the conveying vehicle 1 so that the overall center of gravity of the equipment is biased toward the conveying vehicle 1, thereby ensuring the stability of the deformed conveying frame in clamping the high-pressure tank body when it is in a horizontal plate-like structure.

[0040] The dynamic conveying plate 7 and the static conveying plate 8 are provided with a plurality of U-shaped conveying grooves 15 for clamping and placing the high-pressure tank body, and the dynamic conveying plate 7 and the static conveying plate 8 are provided with a movable through groove 16 inside, and a clamping and lifting assembly is slidably provided inside the movable through groove 16, and a screw driving mechanism for driving the clamping and lifting assembly to move is provided at the top of the static conveying plate 8. Further, the clamping and lifting assembly includes an L-shaped block slidably connected to the inside of the movable through groove 16, and the top of the L-shaped block is fixedly connected to an arc-shaped clamping block 29, and the side wall of the arc-shaped clamping block 29 is fixedly connected to the side wall of the arc-shaped clamping block 29. A threaded connecting arm 18 is fixedly connected. Further, the screw drive mechanism includes a driving shaft 22 rotatably arranged at the top of the static conveying plate 8 and the dynamic conveying plate 7. The surface of the driving shaft 22 is provided with an external thread with an opposite spiral direction, and the external thread is adapted to the threaded connecting arm 18. Further, a driven bevel gear 21 is provided at the middle part of the driving shaft 22. A clamping motor 20 is installed at the top of the dynamic conveying plate 7 and the static conveying plate 8. The output end of the clamping motor 20 is fixedly connected with a driving bevel gear 19 meshing with the driven bevel gear 21.

[0041] It should be noted that: the clamping motor 20 drives the driving bevel gear 19 at its output end to rotate, and the driving bevel gear 19 drives the driven bevel gear 21 meshing therewith to rotate, thereby driving the driving shaft 22 connected to the driven bevel gear 21 to rotate. Under the action of the threaded groove in the opposite direction of the spiral, the driving shaft 22 makes the threaded connecting arm 18 move toward the center of the U-shaped conveying groove 15, thereby driving the arc-shaped clamping block 29 connected thereto to move toward the center of the U-shaped conveying groove 15, thereby clamping and fixing the high-pressure tank body. At the same time, the L-shaped block at the bottom end of the arc-shaped clamping block 29 drives the squeezing roller 17 to move, and the squeezing roller 17 squeezes the arc surface at the bottom end of the high-pressure tank body, so that the squeezing force of the squeezing roller 17 has an upward lifting force on the high-pressure tank body, thereby realizing the lifting function of the high-pressure tank body, so that the bottom end of the high-pressure tank body is separated from the ground, thereby enabling the dynamic conveying plate 7 and the static conveying plate 8 to realize the automatic picking function of the high-pressure tank body, without the need for the conveying personnel to manually place it, thereby improving the placement efficiency and reducing the workload.

[0042] Furthermore, a turning port is provided at the bottom end of the L-shaped block, and an extrusion roller 17 is rotatably provided inside the turning port. A rubber layer is provided on the surface of the extrusion roller 17 to increase the friction between the extrusion roller 17 and the surface of the high-pressure tank body.

[0043] It should be noted that there is a large resistance at the connection between the extrusion roller 17 and the turning port. When the extrusion roller 17 no longer lifts the high-pressure tank body, the high-pressure tank body moves downward under the action of its own gravity, thereby driving the extrusion roller 17 to rotate. Under the action of resistance, the high-pressure tank body can move downward slowly, which is convenient for controlling the high-pressure tank body to perform slow palletizing operations, avoiding excessive impact force between the high-pressure tank bodies during the palletizing process, and ensuring the safety of palletizing.

[0044] When the present invention is used, the high-pressure tanks to be transported that need to be stacked are first arranged on the ground according to the requirements, and when the deformed conveying frame is transformed into a horizontal plate-like structure, the U-shaped conveying trough 15 can be sleeved on the high-pressure tanks;

[0045] First, the deformable conveyor frame is kept to become a frame structure, and then the conveyor vehicle 1 is used to drive the deformable conveyor frame to move, so that the U-shaped conveying groove 15 on the static conveying plate 8 is first engaged with the high-pressure tank on the ground, which can play a positioning role for the deformable conveyor frame, and then the traction motor 5 is turned on, and the traction motor 5 drives the winding roller 3 to rotate in the opposite direction, so that the traction rope 4 is unfolded, and at the same time, under the elastic force of the pushing spring 25, the pushing block 24 pushes the traction top plate 6 to move, thereby making the transfer deformation main rod 9 and the transfer deformation secondary rod 10 in an inclined state. At this time, under the action of the gravity of the traction top plate 6 and the dynamic conveying plate 7, the transfer deformation main rod 9 and the dynamic conveying plate 7 are The inclination of the rod 9 and the transfer deformation secondary rod 10 gradually increases until the two overlap with each other (when overlapping, the notch on the transfer deformation secondary rod 10 is engaged with the rotating shaft on the transfer deformation main rod 9). During this process, the traction top plate 6 and the dynamic conveying plate 7 are always in a horizontal state. Finally, the traction top plate 6, the dynamic conveying plate 7 and the static conveying plate 8 are on the same horizontal plane. After the dynamic conveying plate 7 becomes horizontal, the U-shaped conveying groove 15 on the dynamic conveying plate 7 is automatically sleeved on the surface of the high-pressure tank body (because the high-pressure tank body is placed in advance according to demand, it can be ensured that the U-shaped conveying groove 15 is automatically sleeved on the surface of the high-pressure tank body);

[0046] Then, the clamping motor 20 is turned on, and the clamping motor 20 drives the driving bevel gear 19 at its output end to rotate, and the driving bevel gear 19 drives the driven bevel gear 21 meshing therewith to rotate, thereby driving the driving shaft 22 connected to the driven bevel gear 21 to rotate, and under the action of the thread groove in the opposite direction of the spiral direction of the driving shaft 22, the threaded connecting arm 18 moves toward the center of the U-shaped conveying groove 15, thereby driving the arc-shaped clamping block 29 connected thereto to move toward the center of the U-shaped conveying groove 15, and at the same time, the L-shaped block at the bottom end of the arc-shaped clamping block 29 drives the extrusion roller 17 connected thereto to move toward the direction of the high-pressure tank body, and the extrusion roller 17 will squeeze the arc surface at the bottom edge of the high-pressure tank body (refer to Figure 1 The structure of the medium and high pressure tank body) makes the squeezing force applied by the squeezing roller 17 to the arc surface at the edge of the high pressure tank body have an upward component force, i.e., a lifting force, under the action of the arc surface, to realize the lifting function of the high pressure tank body, so that the bottom end of the high pressure tank body is off the ground. After the squeezing roller 17 completely lifts the high pressure tank body, the arc clamping block 29 contacts the surface of the high pressure tank body to realize the clamping and fixing of the high pressure tank body, thereby making the dynamic conveying plate 7 and the static conveying plate 8 realize the automatic picking function of the high pressure tank body, without the need for the conveying personnel to manually place it, thereby improving the placement efficiency and reducing the workload;

[0047] Afterwards, the traction motor 5 is turned on, and the traction motor 5 drives the winding roller 3 to rotate and wind up the traction rope 4. The traction rope 4 pulls the traction top plate 6 to move upward, so that the originally overlapping transfer deformation main rod 9 and the transfer deformation secondary rod 10 are first changed into an inclined state (at this time, the traction top plate 6, the transfer deformation main rod 9, the transfer deformation secondary rod 10 and the static conveying plate 8 form a parallelogram structure), and then restored to a vertical state, so that the deformed conveying frame restores the frame structure, so that the high-pressure tank body can be temporarily stacked, which is convenient for the transfer of the high-pressure tank body;

[0048] When the deformed conveying frame moves to the carriage of the transport vehicle, the lifting motor 11 is turned on, and the lifting motor 11 drives the driving gear 28 to rotate, and then drives the driven gear 27 meshing therewith to rotate. Since the radius of the driving gear 28 is smaller than the radius of the driven gear 27, the driven gear 27 rotates slowly, and then drives the nut blocks 26 on both sides to move slowly along the bidirectional screw rod, so that the lifting mechanism drives the lifting plate 2 to slowly lift and lower, which is convenient for controlling the stacking height of the high-pressure tank body;

[0049] After the high-pressure tank reaches the stacking height, the deformed conveying frame is changed into a horizontal plate-shaped structure, so that the high-pressure tank changes from the stacking state to a state evenly distributed on the same horizontal plane, and then the conveying vehicle 1 is used to push the deformed conveying frame into the inside of the transport vehicle box, and the lifting mechanism is used to control the lifting plate 2 to slowly descend to a suitable height, and the clamping motor 20 is turned on, so that the squeezing roller 17 slowly moves to both sides, and loses the lifting effect on the bottom end of the high-pressure tank. At this time, the high-pressure tank moves downward under the action of its own gravity, and then drives the squeezing roller 17 to rotate under the action of friction. Under the action of the rotation resistance of the squeezing roller 17, the high-pressure tank can be slowly moved downward to realize the automatic stacking function of the high-pressure tank. At the same time, the high-pressure tank can be controlled to perform slow stacking operations to avoid the phenomenon of high-pressure tanks colliding with each other during the stacking process, thereby ensuring the safety of stacking;

[0050] By repeating the above operation, the automatic stacking and loading function of all high-pressure tanks can be realized. When the high-pressure tanks need to be unloaded, the deformable conveyor frame can be first transformed into a horizontal plate structure, and then the deformable conveyor frame can be allowed to enter the interior of the car and approach the top of the car (the deformable conveyor frame under the horizontal plate structure is adapted to the internal structure of the transport vehicle's car body, that is, when one end of the deformable conveyor frame under the horizontal plate structure touches the inner wall of the car body, it indicates that the U-shaped conveying trough 15 is aligned with the high-pressure tanks), so that the deformable conveyor frame slowly descends, so that the U-shaped conveying trough 15 is sleeved on the high-pressure tanks from top to bottom, so as to realize the picking function of the high-pressure tanks stacked on the top layer, and then the transport vehicle 1 is used to transfer the deformable conveyor frame with the high-pressure tanks picked up out of the car body of the transport vehicle, so that the high-pressure tanks can touch the ground, and the above operation can be repeated to realize the unloading function of the high-pressure tanks inside the car body.

[0051] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
