Description

Technical Field

[0001] The present application relates to the technical field of vehicle loading, and more particularly to a vehicle loading and lifting device for logistics transportation. Background Art

[0002] At present, when loading items onto a vehicle, a common method is to use a forklift to lift and transport them, or to use a conveyor belt to transport them. Although using a forklift or a conveyor belt to transport them can reduce the labor intensity of workers and the input of labor, the forklift requires a larger turning radius to deliver the items into the vehicle. Similarly, when using a conveyor belt for transportation, the rising slope of the conveyor belt cannot be made very steep, so the length of the conveyor belt is also relatively long, occupying a larger space.

[0003] If you encounter a loading environment with a small space, you cannot use forklifts and conveyor belts, and you can only use manual transportation. Although manual transportation is flexible and convenient, it increases the workload of workers and is not suitable for long-term transportation. Summary of the invention

[0054] The present application makes improvements and innovations and proposes the following embodiments.

[0055] In some embodiments, see Figures 1 to 8 , provides a loading and lifting device for logistics transportation, comprising:

[0056] A mobile base 1, wherein a universal wheel 11 is provided at the bottom of the mobile base 1;

[0057] Two support columns 2 extending in the vertical direction, the two support columns 2 are arranged at intervals, and each support column 2 is fixedly connected to the middle position of the mobile base 1;

[0058] A lifting mechanism 3, the lifting mechanism 3 is located between the two support columns 2 and is slidably connected to the support columns 2; the lifting mechanism 3 is driven to lift by a first motor 301, and the lifting mechanism 3 includes a first crossbar 302, a plurality of first rollers 303 arranged at intervals along the extending direction of the first crossbar 302, and a second roller 304 located at one end of the first crossbar 302, and the two adjacent first rollers 303 and the second roller 304 and the first roller 303 are all driven by a first belt 305;

[0059] The translation mechanism 4 includes a second cross bar 42, a plurality of third rollers 43 spaced apart along the extending direction of the second cross bar 42, and a fourth roller 44 meshing with the third rollers 43 for transmission. The second cross bar 42 is slidably connected to the support column 2;

[0060] When the lifting mechanism 3 moves to the state where the translation mechanism 4 is in the same horizontal plane, the second roller 304 is in contact and meshed with the fourth roller 44 , the third roller 43 is driven by the second motor 41 , and two adjacent third rollers 43 are driven by the second belt 45 .

[0061] Among them, the items to be transported are boxes, that is, the products packaged from the factory are generally sealed in designated boxes before being loaded and transported.

[0062] Among them, a motor is fixedly connected to the mobile base 1 , and a second motor 41 is fixedly connected to the second cross bar 42 .

[0063] There are two first crossbars, which correspond to the supporting columns one by one; there are two second crossbars, which correspond to the supporting columns one by one. The first roller and the second roller are both rotatably connected to the first crossbar; the third roller and the fourth roller are both rotatably connected to the second crossbar.

[0064] By providing the lifting mechanism 3, the objects can be lifted vertically, so the length of the lifting mechanism 3 can be made shorter, thereby meeting the requirements of loading work in a smaller loading environment.

[0065] When the lifting mechanism 3 moves to the same horizontal plane as the translation mechanism 4, the second roller 304 engages with the fourth roller 44, thereby driving the rotation of the first roller 303, moving the items on the lifting mechanism 3 to the translation mechanism 4, and continuing to move them on the translation mechanism 4 into the carriage, thereby realizing the process of lifting and carrying the items and reducing the labor intensity of the workers.

[0066] At the same time, the number of motors used to drive the first roller 303 can be reduced, thereby reducing production costs.

[0067] In one embodiment, the lifting mechanism 3 further includes a slider 306 that is buckled and fixed to the first crossbar 302. The support column 2 is provided with a first slide groove 21 for the slider 306 to slide and be clamped. The slider 306 is slidably connected to the first slide groove 21 through a first bearing 307. The combination of the slider 306 and the first slide groove 21 can make the first crossbar 302 rise and fall more smoothly.

[0068] Specifically, the slider 306 is fixed to the first crossbar 302 by mortise and tenon joints. A slot is provided in the slider 306, and a block 3025 matching the slot is provided on the first crossbar 302. The block 3025 is inserted into the slot for buckle connection. The buckle design is easy to disassemble and install, and is convenient for workers to repair.

[0069] Specifically, the block 3025 is a rectangular block, which can prevent the block 3025 from rotating after being inserted into the slot, and ensure that the first crossbar 302 will not rotate relative to the slider 306.

[0070] In one solution, both ends of the first chute 21 are provided with a driving wheel 308, a chain 309 is meshed and connected to the driving wheel 308, the driving wheel 308 is transmission-connected to the first motor 301 through a driving rod 3010, and a slider 306 is fixedly connected to the chain 309. The slider 306 is provided with a through hole 3012 for the chain 309 to pass through, and the cross section of the slider 306 is a trapezoidal shape that matches the first chute 21. Compared with the screw drive, the sprocket drive can quickly realize the lifting and lowering of the first crossbar 302, thereby improving the loading efficiency.

[0071] Specifically, the top of the support column 2 is a top cover 22, which is detachably (detachably by bolts) buckled on the first slide slot 21, and the driving wheel 308 is rotatably connected to the inner wall of the first slide slot 21. The top cover 22 is designed to prevent the slider 306 from accidentally sliding out of the first slide slot 21.

[0072] In one solution, the first slide groove 21 is a dovetail groove, and the first bearing 307 is in close contact with the side of the first slide groove 21. The dovetail groove design can prevent the slider 306 from sliding out of the first slide groove 21.

[0073] Specifically, there are multiple first bearings 307, which are symmetrically distributed on both sides of the slider 306. The first bearings 307 are distributed at intervals along the extension direction of the first slide groove 21. The use of multiple first bearings 307 can ensure that the slider 306 is subjected to uniform force.

[0074] In one embodiment, the first cross bar 302 is provided with an inclined first movable groove 3021 and a second movable groove 3022, and the first roller 303 and the second roller 304 are slidingly connected to the first movable groove 3021 and the second movable groove 3022 respectively, and the two adjacent first rollers 303 and the first roller 303 and the second roller 304 are hinged by a connecting rod 3011.

[0075] The first moving groove 3021 and the second moving groove 3022 are arranged so that after the second roller 304 abuts against the fourth roller 44, under the action of external force, the second roller 304 moves in the second moving groove 3022, and the connecting rod 3011 pushes the first roller 303 to move in the first moving groove 3021, thereby changing the height position of the first roller 303, so that the first roller 303 contacts the object; since the second roller 304 contacts the fourth roller 44, the fourth roller 44 drives the second roller 304 to rotate, thereby driving the first roller 303 to rotate, and the rotating first roller 303 drives the object to move toward the translation mechanism 4.

[0076] Specifically, the connecting rod 3011 is located at both ends of the first roller 303, the first roller 303 is slidably connected to the first moving groove 3021 through the second bearing, and the second roller 304 is slidably connected to the second moving groove 3022 through the third bearing, and the first moving groove 3021 and the second moving groove 3022 are inclined in opposite directions. The provision of the bearings can reduce the resistance when the first roller 303 and the second roller 304 move in the moving grooves.

[0077] Specifically, the connecting rod 3011 is also hinged to the first roller 303 and the second roller 304 through a bearing, so as to better push the first roller 303 to move in the moving groove.

[0078] In one solution, the first moving groove 3021 has an inclined section 3023 and a horizontal section 3024. When the first roller 303 is on the inclined section 3023, the top of the first roller 303 is located below the plane where the top of the first crossbar 302 is located. When the first roller 303 is on the horizontal section 3024, the top of the first roller 303 is located above the plane where the top of the first crossbar 302 is located. When the first roller 303 is on the horizontal section 3024, the gravity of the article received is equal to the supporting force and the opposite direction, and the separation driving connecting rod 3011 will not be generated. The force of the connecting rod 3011 is reduced, and then the retreat force is reduced, ensuring the abutment force of the second roller 304 and the fourth roller 44. The service life of the second roller 304 and the fourth roller 44 is improved.

[0079] Specifically, a return mechanism is provided at one end of the first cross bar 302 (the end of the first cross bar 302 away from the second roller 304), which includes: a spring 3013 and a push plate 3014, one end of the spring 3013 abuts against the first cross bar 302, and the other end abuts against the push plate 3014, and the push plate 3014 abuts against the rotating shaft of the first roller 303 adjacent to it.

[0080] A spring 3013 and a push plate 3014 are provided. When the second roller 304 and the fourth roller 44 are in contact, the rotating shaft of the first roller 303 pushes and squeezes the spring 3013, and the spring 3013 stores energy. When the second roller 304 and the fourth roller 44 are separated, the spring 3013 pushes the push plate 3014 and then pushes the first roller 303 to retreat and reset. The top of the first roller 303 is located below the plane where the top of the first cross bar 302 is located. At this time, when an object (box) is placed, the force is on the first cross bar 302, and the first roller 303 is not subjected to force. The friction force of the object on the first cross bar 302 is large, and it is not easy to slide out of the lifting mechanism 3.

[0081] In one embodiment, it also includes: a processor 5, a first pressure sensor 6, a second pressure sensor 7, and a third pressure sensor 8; the first pressure sensor 6 is arranged at the connection between the first cross bar 302 and the slider 306, the second pressure sensor 7 is located at the bottom of the second movable groove 3022, the third pressure sensor 8 is fixedly connected to the second cross bar 42, and the third pressure sensor 8 is located at the connection between the second cross bar 42 and the support column 2; the first motor 301, the second motor 41, the first pressure sensor 6, the second pressure sensor 7, and the third pressure sensor 8 are all electrically connected to the processor 5.

[0082] After the item is placed, the pressure of the first pressure sensor 6 increases, and the signal transmitted to the processor 5 exceeds the first threshold value. At this time, the processor 5 outputs a signal to the first motor 301 and the second motor 41. The second motor 41 drives the third roller 43 to rotate, thereby driving the fourth roller 44 to rotate. The first motor 301 drives the driving wheel 308 to rotate, driving the chain 309 to rotate, thereby lifting the lifting mechanism 3. When the second roller 304 and the fourth roller 44 are in contact, the output signal of the second pressure sensor 7 increases. When the signal reaches or exceeds the second threshold value, it means that the first cross bar 302 and the second cross bar 42 are at the same level, and the processor 5 outputs The signal to stop the rotation is given to the first motor 301, and the rotating third roller 43 drives the fourth roller 44 to rotate, the fourth roller 44 drives the second roller 304 to rotate, and the second roller 304 drives the first roller 303 to rotate, so the object is moved to the third roller 43 in the translation mechanism 4. At this time, the third sensor inputs a signal to the processor 5 as the third threshold standard. When the signal value of the third sensor is suddenly less than the third threshold, it means that the object has been taken away. At this time, the processor 5 outputs a signal to stop the second motor 41, and starts the first motor 301 to rotate in the direction at the same time. When the lifting mechanism 3 moves to the initial position, the rotation of the first motor 301 is stopped. The initial position is determined to be an infrared sensor set at the initial position. The infrared sensor is electrically connected to the processor 5. When the motor is reversed and the infrared signal is blocked, the processor 5 outputs a signal to stop the rotation of the first motor 301. The automation capability of the device is improved and the workload of the workers is reduced.

[0083] Specifically, the processor 5 is also electrically connected to a control screen 51, which may also be a mobile terminal, and the processor 5 is connected to the mobile terminal via wireless transmission. This improves the automated control capability.

[0084] In one embodiment, the fourth roller 44 is located below the third roller 43 .

[0085] In one solution, the second crossbar 42 is provided with a second slide groove 421, which is sleeved on the support column 2 and slidably connected to the support column 2. The arrangement is reasonable to ensure smooth sliding.

[0086] After the lifting mechanism is in contact with the translation mechanism, the first drive motor can be manually started to adjust the height position of the translation mechanism, so that the height of the translation mechanism reaches a suitable position to facilitate loading.

[0087] Specifically, a roller 422 is provided on the inner side wall of the second slide groove 421, the second cross bar 42 is slidably connected to the support column 2 through the roller 422, and the third pressure sensor 8 is located on the rotating shaft of the roller 422. The third pressure sensor 8 is located on the rotating shaft of the roller 422 to ensure smooth sliding, because this position is most sensitive to the change of torque, and the design is reasonable.

[0088] In one solution, the second crossbar 42 is also provided with a lifting assembly 9, which includes: a third motor 91, a worm 92 connected to the third motor 91, a worm wheel 93 meshing with the worm 92, and a driving gear 94 fixedly connected with the worm wheel 93; a receiving cavity is provided on the side of the second slide slot 421, the third motor 91 is fixedly connected to the second crossbar 42, the worm wheel 93, the worm 92, and the driving gear 94 are all located in the receiving cavity, the driving gear 94 is coaxially arranged with the worm wheel 93, and a rack 95 extending in the vertical direction is fixedly provided on the support column 2, and the driving gear 94 meshes with the rack 95. The transmission of the worm wheel 93 and the worm 92 avoids the situation that the translation mechanism 4 automatically slides when the third motor 91 stops driving, because only the worm 92 can drive the worm wheel 93, and the worm wheel 93 cannot drive the worm 92, thereby ensuring the safety of use.

[0089] Specifically, the rack 95 is opened on the support column 2.

[0090] Specifically, the third motor 91 is electrically connected to the processor 5 , and a stop, lift, and lower switch is provided on the third motor 91 for driving the translation mechanism 4 to rise and fall to adapt to the heights of different receiving platforms.

[0091] The above are only optional embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
