The lifting device for cargo handling includes: a bracket 1, a walking assembly 2, a supporting assembly 3, a clamping assembly 4 and a lifting assembly 5. The walking assembly 2 is connected to the bracket 1, and is used to drive the bracket 1 to move freely. The supporting assembly 3 is connected to the bracket 1, and is used to temporarily store materials. The clamping assembly 4 includes a sliding member 41 and a clamping unit 42. The sliding member 41 is connected to the bracket 1 and can slide close to or away from the supporting assembly 3. The clamping unit 42 is movably connected to the sliding member 41, and is used to clamp or release materials. The lifting assembly 5 is connected to the bracket 1 and the clamping unit 42, and is used to drive the clamping unit 42 to rise and fall.

[0022] In this device, a support component 3, a clamping component 4 and a lifting component 5 are provided on the bracket 1. The support component 3 is used for temporarily storing materials. The clamping component 4 includes a sliding member 41 and a clamping unit 42. The clamping unit 42 can clamp or release materials. The lifting component 5 can drive the sliding member 41, the clamping unit 42 and the materials to rise and fall relative to the support component 3, so as to temporarily store the clamped materials on the support component 3. At the same time, the bracket 1 is arranged on the walking component 2 to realize the movement of the bracket 1.

It is not only simple in structure and easy to operate, but also can reduce the labor intensity for the handling of goods and improve the efficiency of goods handling. It can solve the problem in the prior art that the traditional crane gripper type is relatively single and difficult to adapt to the handling needs of goods of different shapes and materials, resulting in inconvenience in use.

The motor fixing plate 23 is used to fix the GM6020 pan-tilt motor 27 on the turntable 22, and a steering wheel 25 is fixed below the turntable 22. There are motor fixing cover plates 24 fixed by bolts on both sides of the steering wheel 25. The motor fixing cover plate 24 can fix the M3508 DC reduction brushless motor 26, so that the brushless motor 26 is connected to the steering wheel 25 shaft. The GM6020 pan-tilt motor can control the turntable 22 to turn the steering wheel 25. The present invention adopts a four-steering wheel 25 driving mode, which is flexible and powerful, can move freely in a small space and travel at high speed, has a strong load-bearing capacity, effectively overcomes the slipping phenomenon during the movement, and has high positioning accuracy. The M3508 DC reduction brushless motor 26 is used for traveling.

[0025] Furthermore, a tracking sensor is installed on each of the four integral frame legs 21. The sensor TSL1401 is a linear charge-coupled device (CCD) image sensor, which can capture 128 pixels in a single row and output them as analog signals. These output signals can be converted into digital signals, so that the device can determine the walking direction according to the main control board program. After determining the walking direction, the four steering motors at the travel mechanism are controlled through the CAN bus to accurately control the travel direction of each wheel. The four driving wheel motors are controlled through another CAN bus to realize the movement of the crane in all directions. The steering wheel is equipped with an absolute encoder to accurately control the travel direction of each wheel.

[0026] Furthermore, the present invention adopts Raspberry Pi as the main control unit, and detects the position and angle of the crane in the site through OpenCV and the tracking module when moving, and cooperates with the path planning algorithm to ensure fast and accurate walking.

The second linear drive here is a push rod motor, a hydraulic cylinder and an air cylinder that are common and easy to purchase on the market. This belongs to a conventional setting known to those skilled in the art and will not be described in detail here.

[0034] In one embodiment, if Figure 7 As shown, the limit plate 33 is arranged on the ascending path of the bottom support 31 and can abut against the material to limit the bottom support 31 from continuing to drive the material to ascend relative to the support frame 11 and to hold the material in the temporary storage chamber.

The sliding plate 412 is connected to the first slide rail 411 along the guide sliding of the first slide rail 411. The first driving part 413 has a fixed end and a movable end. The fixed end of the first driving part 413 is connected to the translation frame 12, and the movable end is connected to the sliding plate 412, which is used to drive the sliding plate 412 to slide along the guide of the first slide rail 411, and the clamping unit 42 is movably connected to the sliding plate 412.

[0037] The first slide rail 411 supports and guides the sliding of the sliding plate 412 , and the first driving part 413 drives the sliding of the sliding plate 412 .

[0040] The first driving motor 4133 drives the synchronous wheel 4131 to rotate, so that the synchronous belt 4132 sleeved on the synchronous wheel 4131 can slide relative to the first slide rail 411, thereby realizing the driving effect on the sliding plate 412.

[0041] Furthermore, the number of the first slide rails 411 in the sliding member 41 is two, and the two guide blocks 414 are both connected to the sliding plate 412, which can improve the stability of the operation of the device.

[0042] Furthermore, there are two first drive parts 413 in the present device, and the two first drive motors 4133 synchronously drive the two synchronous wheels 4131 to rotate, which can improve the stability of the device operation and improve the efficiency of the device in carrying heavy objects. Here, the synchronous wheels 4131, synchronous belts 4132 and first drive motors 4133 are all common and easy-to-purchase equipment on the market. This is a conventional setting known to technicians in this field and will not be elaborated here.

The fixed end of the second driving member is connected to the fixed seat 51, and the movable end is connected to the clamping plate 421, which is used to drive the two clamping plates 421 to rotate closer to or away from each other to clamp or release the material.

[0045] Driven by the second driving part 423 , the two clamping plates 421 can rotate relative to the fixing seat 51 respectively, so as to clamp or release the material. The abutting part here is elastic, which can improve the stability of the device in clamping the material.

[0046] Furthermore, the clamping unit 42 here also includes a parallelogram connecting rod portion 425, and the clamping plate 421 and the movable end of the second driving portion 423 are rotationally connected via the parallelogram connecting rod portion 425, which can improve the stability of the rotation of the device.

The suction cup 424 and the negative pressure vacuum pump are common and easy-to-purchase equipment on the market, which are conventional settings known to technicians in this field and will not be described in detail here.

[0051] In one embodiment, if Figure 1 , Figure 7 As shown, the width of the limiting plate 33 is smaller than the minimum distance between the two suction cups 424 when clamping the material, so that after the two suction cups 424 absorb the material, the limiting plate 33 can pass through the gap between the two suction cups 424, thereby avoiding the limiting plate 33 from interfering with the suction cups 424 in clamping or releasing the material.

[0052] Furthermore, a waist-shaped groove is provided on the limiting plate 33, and the waist-shaped groove passes through the limiting plate 33, so that when stacking materials, when the two clamping plates 421 clamp materials with small diameters, the materials with small diameters can pass through the waist-shaped groove and stack the materials with small diameters on the bottom support 31, thereby avoiding the limiting plate 33 from interfering with the clamping plates 421 in clamping or releasing materials, which will not be elaborated here.

[0054] The fixing seat 51 is used to support and connect the two clamping plates 421 and realize the lifting and lowering between the relative sliding plates 412 .

[0055] Furthermore, if Figures 4 to 6As shown, the first linear drive component 52 here includes a lifting ring 521, a guide pulley 522, a winding wheel 523, a steel wire rope and a second driving motor 525. The lifting ring 521 is connected to the fixed seat 51 and can pass through the sliding plate 412. The second driving motor 525 is connected to the sliding plate 412. By winding the steel wire on the winding wheel 523, and the other end of the steel wire rope passes through the sliding plate 412 and is connected to the lifting ring 521, the output shaft of the second driving motor 525 is coaxially arranged with the winding wheel 523, and when the winding wheel 523 rotates, it can drive the fixed seat 51 to rise and fall relative to the sliding plate 412. Here, the lifting ring 521, the guide pulley 522, the winding wheel 523, the steel wire rope and the second driving motor 525 are all common and easy-to-purchase equipment on the market, which belongs to the conventional settings well known to those skilled in the art and will not be described in detail here.

[0057] The guide hole and the guide shaft 53 cooperate with each other to improve the stability during the lifting process.

[0058] Furthermore, the number of the guide shafts 53 is two, the two guide shafts 53 are spaced apart from each other, and are both connected to the fixing seat 51 .

[0059] In order to better understand the present invention, the following Figures 1 to 7 The technical solution of the present invention is described in detail: The support 1 is provided with a support assembly 3, a clamping assembly 4 and a lifting assembly 5. The support assembly 3 is used for temporarily storing materials. The clamping assembly 4 includes a sliding member 41 and a clamping unit 42. The clamping unit 42 can be used to clamp or release materials. The lifting assembly 5 can drive the sliding member 41, the clamping unit 42 and the materials to rise and fall relative to the support assembly 3, so as to temporarily store the clamped materials on the support assembly 3. Meanwhile, the support 1 is provided on the walking assembly 2, so as to realize the free movement of the support 1. Compared with the prior art, by arranging the sliding member 41 and the clamping unit 42 on the support 1, so as to clamp or release the materials, the lifting assembly 5 is connected with the sliding member 41, so as to drive the sliding member 41, the clamping unit 42 and the materials to rise and fall relative to the support assembly 3, so that the clamped materials can be temporarily stored on the support assembly 3, and then the support 1 and the materials are transported to the designated area through the walking assembly 2. The structure is simple and the operation is convenient. The labor intensity for the handling of goods can be reduced and the efficiency of the handling of goods can be improved.

[0060] The beneficial effect of the present invention is that the traditional mechanical gripper and the pneumatic suction cup 424 gripper are combined to form a dual-purpose gripper, which can directly grasp objects with different surface structures, and the two symmetrically distributed suction cups 424 can enhance the suction reliability and stability.

[0061] At the same time, the present invention adopts a forklift-type storage area as a self-unloading mechanism, and realizes self-unloading by driving the hydraulic rod through the push rod motor to drive the frame to move up and down. A cargo base 31 is provided on the frame to place the cargo, and a limit plate 33 for the gripper to pass through is provided to ensure that the cargo is placed stably, which greatly improves the work efficiency and transportation efficiency and is suitable for port logistics handling work.

[0062] In addition, the present invention uses a steering wheel 25 chassis and adopts a four-steering wheel 25 driving mode. The GM6020 pan / tilt motor controls the steering of the turntable 22 to control the steering of the steering wheel 25, so that the crane is flexible and powerful, can move freely in a small space at high speed, has a strong load-bearing capacity, overcomes the wheel slip phenomenon, and improves positioning accuracy.

[0063] Furthermore, in terms of control, the present invention innovatively combines image recognition with the tracking system: OpenCV is used to obtain the cargo position, which is processed into a digital signal and transmitted to the STM32 microcontroller for route planning. At the same time, TSL1401 tracking sensors are installed on the four legs of the crane, and the analog signals they output are converted into digital signals. The walking direction is determined according to the main control board program, and the position and angle are detected during movement through OpenCV and the tracking module, which cooperates with the path planning algorithm to ensure fast and accurate walking.

[0064] Through the above structure, the device can solve the problem in the prior art that the traditional crane gripper has a single type and is difficult to adapt to the needs of handling goods of different shapes and materials, thus causing inconvenience in use.

[0065] The specific implementation of the present invention described above does not constitute a limitation on the protection scope of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the protection scope of the claims of the present invention.
