Description

Technical Field

[0001] The present application relates to the technical field of loaders and unloaders, and in particular to a swing positioning device for loaders and unloaders. Background Art

[0002] A loader is a type of unloading equipment that is equipped with multiple conveyor belts to quickly transfer the cargo from a truck to the outside of the truck.

[0003] In the related technology, the loader and unloader include a conveying mechanism, a traveling mechanism and a rotation adjustment mechanism. The conveying mechanism is arranged on the traveling mechanism and is used to convey the goods. The rotation adjustment mechanism is arranged on the traveling mechanism and is used to adjust the horizontal direction of the conveying mechanism so that the loader and unloader can be aligned with the unloading position on the truck. The traveling mechanism rolls in contact with the ground and is used to drive the pile body of the loader and unloader to move.

[0004] In the above-mentioned related technologies, after the rotating adjustment mechanism completes the fine adjustment of the orientation angle of the conveying mechanism, there is a lack of corresponding braking limit, so that when the loader and unloader is subjected to thrust, the walking mechanism is prone to automatic sliding, which is not conducive to maintaining stable transportation of goods. Utility Model Content

[0006] The present application provides a swing positioning device for a loader and unloader using the following technical solution:

[0007] A swing positioning device for a loader and unloader, comprising:

[0008] The walking mechanism is provided with an AGV steering wheel, which is in rolling contact with the ground to provide walking power;

[0010] A conveying mechanism is arranged on a side of the walking mechanism away from the ground, the conveying mechanism is provided with a rotating bracket, the rotating bracket is rotatably connected to the turntable bearing, and the conveying mechanism rotates circumferentially around the turntable bearing;

[0011] An electromagnetic mechanism is fixedly connected to the walking mechanism and is used for adsorbing or releasing the rotating bracket.

[0012] By adopting the above technical solution, after the rotating mechanism completes the adjustment, the electromagnetic mechanism generates and eliminates magnetic force to achieve adsorption and limiting of the rotating mechanism, so that the rotating mechanism is not easy to rotate by itself when subjected to external force, and the stability of cargo transportation can be better maintained.

[0013] Optionally, the electromagnetic mechanism includes an electromagnet and an electromagnetic relay, the electromagnetic relay is connected to the electromagnet, the electromagnet is connected and fixed to the walking mechanism, the turntable bearing is sleeved on the circumference of the electromagnet, and a metal adsorption block is fixedly provided on the side wall of the rotating bracket facing the turntable bearing, and when the electromagnetic relay controls the electromagnet to generate magnetic force, the metal adsorption block and the electromagnet attract each other.

[0014] By adopting the above technical solution, the electromagnetic relay connects the electromagnet and controls the electromagnet to generate or eliminate magnetic force, so as to achieve the attraction control between the electromagnet and the metal adsorption block, so that the rotating mechanism is not easy to rotate by itself.

[0015] Optionally, a supporting bracket is fixedly provided on one side surface of the walking mechanism, and a connecting flange is fixedly provided on the side wall of the supporting bracket facing the rotating bearing, and the connecting flange is detachably connected to the turntable bearing.

[0016] By adopting the above technical solution, the supporting bracket is detachably connected to the turntable bearing through the connecting flange, so that the turntable bearing can be disassembled and repaired when it is damaged. At the same time, the supporting bracket provides a stable supporting force for the turntable bearing.

[0017] Optionally, a receiving groove is provided on the surface of one side of the walking mechanism facing the ground, the supporting bracket is fixedly connected to the bottom of the receiving groove, and a connecting hole is provided on the side wall of the bottom of the receiving groove, and the connecting hole is used for the lower end of the rotating bracket to pass through and be fixedly connected to the connecting plate.

[0018] By adopting the above technical solution, the opening of the accommodating groove provides accommodating space for the supporting bracket and the turntable bearing, reducing the space occupied when installed on the walking mechanism. At the same time, it makes the turntable bearing less likely to be damaged by contact with foreign objects, which helps to improve the stability of use.

[0019] Optionally, the turntable bearing includes an inner ring and an outer ring, the outer ring is connected and fixed to the walking mechanism, the inner ring is connected and fixed to the rotating bracket, and the inner ring is arranged on the circumference of the electromagnet.

[0021] Optionally, a buffer is fixedly provided on the side wall of the electromagnet facing the metal adsorption block, and when the electromagnet and the metal adsorption block are attracted, the metal adsorption block is pressed against the surface of the buffer.

[0022] By adopting the above technical solution, the setting of the buffer part provides abutment buffer when the electromagnet and the metal adsorption block are attracted to each other, making it difficult for adsorption collision to occur between the metal adsorption block and the electromagnet, reducing the probability of damage to the electromagnet and helping to extend its service life.

[0023] Optionally, the buffer is arranged in a circular ring shape, the outer diameter of the circumferential side of the buffer is the same as the outer diameter of the electromagnet, and the buffer is arranged concentrically with the electromagnet.

[0024] By adopting the above technical solution, when the buffer is arranged in a circular ring shape, it can provide an annular buffer contact surface for the metal adsorption block when it abuts, so that the metal adsorption block can obtain uniform collision buffering, which helps to improve the buffering effect.

[0025] Optionally, an elastic sheet is fixedly provided on the surface of the electromagnet facing the metal adsorption block, and the elastic sheet is concentrically arranged with the buffer. When the electromagnet eliminates the magnetic force, the elastic sheet has a tendency to drive the metal adsorption block away from the electromagnet.

[0026] By adopting the above technical solution, the setting of the elastic sheet can further increase the buffering effect on the metal adsorption block. At the same time, when the electromagnet eliminates the magnetic force, the elastic sheet drives the metal adsorption block away from the electromagnet, so that friction loss is not easily generated between the metal adsorption block and the electromagnet when the rotating mechanism is rotated and adjusted.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. After the rotating mechanism is adjusted, the electromagnetic mechanism generates and eliminates magnetic force to achieve adsorption and limiting of the rotating mechanism, so that the rotating mechanism is not easy to rotate by itself when subjected to external force, and can better maintain the stability of cargo transportation;

[0029] 2. The setting of the buffer part provides abutment buffer when the electromagnet and the metal adsorption block attract each other, so that it is not easy to produce adsorption collision between the metal adsorption block and the electromagnet, reducing the probability of damage to the electromagnet and helping to extend the service life; BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] The following is combined with Figure 1-6 The present application is further described in detail. In this embodiment, the direction indicated by the coordinate axis z in the figure is upward, and the direction opposite to the z axis is downward.

[0038] The present application embodiment discloses a swing positioning device for a loader. Figure 1 and Figure 2 The swing positioning device of the loader and unloader includes a walking mechanism 1, a rotating mechanism 2, a transmission mechanism 3 and an electromagnetic mechanism 4. The walking mechanism 1 is in rolling contact with the ground. The rotating mechanism 2 is arranged on the upper side of the walking mechanism 1 and is rotatably connected with the walking mechanism 1. The transmission mechanism 3 is provided with a rotating bracket 34. The rotating bracket 34 is rotatably connected with the rotating mechanism 2. The electromagnetic mechanism 4 is arranged on the walking mechanism 1, and is used to generate or eliminate magnetic force to adsorb, limit or release the rotating bracket 34, so that after the rotating mechanism 2 is rotated and adjusted, it is not easy to rotate by itself without human adjustment.

[0039] Reference Figure 1 and Figure 2The walking mechanism 1 includes a supporting chassis 11 and an AGV steering wheel 12. A roller 15 is fixedly arranged on the lower side wall of the supporting chassis 11. The roller 15 rolls against the ground. The AGV steering wheel 12 is fixedly arranged on the lower side wall of the chassis to provide driving force, thereby driving the loader to move. The AGV steering wheel 12 has a motor and a reduction gear. The motor and the reduction gear cooperate with each other to convert the transmission force into driving force to drive the walking mechanism 1 to move.

[0040] Reference Figure 1 and Figure 2 The conveying mechanism 3 includes a conveying frame 31, a conveying motor 32 and a conveyor belt 33. The conveying motor 32 and the conveyor belt 33 are both arranged on the conveying frame 31. The conveyor belt 33 and the conveying motor 32 are connected by gears. Driven by the conveying motor 32, the conveyor belt 33 transports the goods to one side. In this embodiment, the conveying frame 31, the conveying motor 32 and the conveyor belt 33 are each provided with two groups, and the longer group of the conveyor belt 33 is connected and fixed to the rotating mechanism 2.

[0041] In addition, refer to Figure 2 The conveyor frame 31 is also hinged with a rotating bracket 34, and the upper side wall of the rotating bracket 34 is extended with a hinge rod 341, and the number of hinge rods 341 is set to two. The hinge rod 341 and the conveyor frame 31 are hinged, so that the conveyor belt 33 is tilted upward from the lower position toward the hinge in the vertical direction. Among them, the rotating bracket 34 is also provided with an adjusting cylinder 35, and the adjusting cylinder 35 is connected and fixed to the rotating bracket 34. The adjusting cylinder 35 has a telescopic shaft 351, and the end of the telescopic shaft 351 is hinged with the lower side wall of the conveyor frame 31, so that the adjusting cylinder 35 can adjust the inclination angle of the conveyor belt 33 by controlling the telescopic distance of the telescopic shaft 351.

[0042] Reference Figure 3-5 The rotating mechanism 2 includes a turntable bearing 21 and a connecting plate 22. The turntable bearing 21 includes an inner ring 211 and an outer ring 212. The inner ring 211 is rotatably connected to the inner wall of the outer ring 212. The upper surface of the inner ring 211 is fixed to the connecting plate 22 by bolts, and the lower surface of the outer ring 212 is connected and fixed to the supporting chassis 11, so that the outer ring 212 remains relatively different and the inner ring 211 can rotate. In addition, the upper surface of the connecting plate 22 is connected and fixed to the lower side wall of the rotating bracket 34, so that the rotating bracket 34 can be synchronously rotated and adjusted with the conveying frame 31 without hindrance.

[0043] Reference Figure 3-5It should be further explained that a receiving groove 111 is provided on the lower side wall of the supporting chassis 11, and a connecting hole 112 is provided on the side wall of the bottom of the receiving groove 111, and the connecting hole 112 is used for the lower end of the rotating bracket 34 to pass through and be fixedly connected to the connecting plate 22. In addition, a supporting bracket 13 is fixedly connected to the bottom of the receiving groove 111, and the supporting bracket 13 is directly below the connecting hole 112. A connecting flange 14 is fixedly provided on the supporting bracket 13, and the connecting flange 14 is detachably connected to the lower surface of the outer ring 212 by bolts, so as to provide a supporting force for the outer ring 212, and can reduce the space occupied by the outer ring 212 and the inner ring 211 during installation, and reduce the probability of contact with foreign objects.

[0044] Reference Figure 3-5 The electromagnetic mechanism 4 includes an electromagnet 41 and an electromagnetic relay 42. The electromagnet 41 is arranged in a cylindrical shape. The electromagnetic relay 42 is connected to the electromagnet 41 to control the electric energy power passed into the electromagnet 41, so as to realize the strength control of the magnetism of the electromagnet 41 and eliminate the magnetism. In this embodiment, the diameter of the electromagnet 41 is adapted to the diameter of the inner ring 211. During installation, the electromagnet 41 is connected and fixed to the supporting bracket 13, and the inner ring 211 surrounds the circumference of the electromagnet 41 to further reduce the space occupation, so that the electromagnet 41 is directly below the rotating connecting disk 22 and close to each other. The lower side wall of the connecting disk 22 is provided with a metal adsorption block 23. The metal adsorption block 23 is a magnetic metal. When the electromagnet 41 generates magnetism, it can adsorb the metal adsorption block 23, so that the connecting disk 22 is not easy to rotate by itself. When the electromagnet 41 eliminates the magnetism, the metal adsorption block 23 and the electromagnet 41 are separated.

[0045] Reference Figure 6 A buffer 43 is fixedly provided on the upper surface of the electromagnet 41. The buffer 43 is made of elastic rubber material and is arranged in a circular ring shape. The buffer 43 and the electromagnet 41 are arranged concentrically. When the electromagnet 41 and the metal adsorption block 23 are attracted to each other, the electromagnet 41 and the buffer 43 abut against each other. Since the buffer 43 is arranged in a circular ring shape, the buffer 43 can provide a uniform buffering abutment force.

[0046] Reference Figure 5 and Figure 6In order to ensure that the electromagnet 41 and the metal adsorption block 23 can be automatically separated after the magnetism of the electromagnet 41 is eliminated, an elastic sheet 44 is fixedly provided on the upper surface of the electromagnet 41. The elastic sheet 44 is arranged at the center of the upper surface of the electromagnet 41 and is concentric with the buffer 43, which can further increase the buffering capacity of the metal adsorption block 23. At the same time, when the electromagnet 41 eliminates the magnetic force, the metal adsorption block 23 can be isolated to a side away from the electromagnet 41. Therefore, when the metal adsorption block 23 rotates synchronously with the connecting disk 22, friction loss is not easily generated between the metal adsorption block 23 and the electromagnet 41, which helps to extend the service life.

[0047] The implementation principle of the rotating positioning device of a loader and unloader in an embodiment of the present application is as follows: after the rotating bracket 34 drives the conveying mechanism 3 to adjust the horizontal orientation angle, the electromagnetic relay 42 is used to control the electromagnet 41 to generate magnetism, so that the metal adsorption block is adsorbed by the magnetic force and a rotation limit is generated, so that the rotating bracket 34 is not easy to rotate by itself, so as to maintain stability during the conveying of goods. When the rotating bracket 34 needs to be adjusted again, the electromagnetic relay 42 is used to control the electromagnet 41 to eliminate or weaken the magnetism.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
