[0036] Compared to existing technologies, this new technology, by installing a sliding member 41 and a clamping unit 42 on the support 1 for clamping or releasing materials, and connecting the lifting component 5 to the sliding member 41 to drive the sliding member 41, clamping unit 42, and materials to rise and fall relative to the support component 3, allows the clamped materials to be temporarily stored on the support component 3. The traveling component 2 then transports the support 1 and materials to a designated area. This design is not only simple in structure and easy to operate, but also reduces labor intensity and improves the efficiency of goods handling. It solves the problem in existing technologies where traditional crane grippers are limited in type and difficult to adapt to the handling needs of goods of different shapes and materials, leading to inconvenience in use.

[0037] Specifically, such as Figure 3 As shown, the walking assembly 2 includes four integral frame legs 21, four turntables 22, four motor mounting plates 23, four motor mounting covers 24, four steering wheels 25, and four brushless motors 26. These are connected to the integral frame legs 21 via bushings. The motor mounting plates 23 are fixed below the bushings, securing the GM6020 gimbal motor 27 to the turntables 22.

The steering wheels are equipped with absolute encoders, which can precisely control the traveling direction of each wheel.

[0039] Furthermore, this utility model uses a Raspberry Pi as the main control unit. When moving, the position and angle of the crane in the field are detected by OpenCV and the line tracking module. The path planning algorithm ensures fast and accurate movement. The Raspberry Pi, OpenCV and the line tracking module are all conventional settings known to those skilled in the art, and will not be described in detail here.

[0040] As shown in Figure 2 The support frame 11 has a temporary storage cavity, and the support assembly 3 is connected to the inner wall of the temporary storage cavity and can slide relative to the support frame 11 in the vertical direction.

Here, the support frame 11 and the translation frame 12 are both formed by welding aluminum alloy commonly available on the market and easy to purchase, which is a conventional arrangement known to those skilled in the art and will not be described in detail here.

[0043] As shown in Figure 7 The support assembly 3 includes at least one bottom support 31, a second linear drive 32, and a limiting plate 33.

[0044] The bottom support 31 is in the shape of an "L" and is formed with a temporary storage groove for accommodating the material.

The limiting plate 33 can cooperate with the bottom support 31 to fix the material in the temporary storage cavity, avoid the material from falling when the support 1 moves, and thus improve the stability and efficiency of material handling.

[0049] In this embodiment, as shown in Figures 4 to 6 The translation frame 12 is hollow. The sliding member 41 comprises at least one first sliding rail 411, a sliding plate 412 and at least one first driving part 413. The first sliding rail 411 is transverse to the translation frame 12 along the length direction of the translation frame 12 and connected to the translation frame 12. The sliding plate 412 is slidingly connected to the first sliding rail 411 along the guide of the first sliding rail 411. The first driving part 413 has a fixed end and a movable end.

[0051] Further, in the device, as shown in Figures 4 to 6 The sliding member 41 further comprises at least one guide block 414. The guide block 414 is arranged one-to-one corresponding to the first sliding rail 411 and slidingly nested on the first sliding rail 411 and connected to the sliding plate 412.

[0052] In one of the embodiments, as shown in Figures 4 to 6 The number of the first sliding rails 411 in the sliding member 41 is two, the two first sliding rails 411 are parallel and spaced apart, and are both connected to the translation frame 12, and the sliding plate 412 is slidingly connected to the two first sliding rails 411.

The fixed end of the first driving motor 4133 is connected to the translation frame 12, and the output shaft is connected to one of the synchronous belts 4132, for driving the sliding block to slide along the guide of the first sliding rail 411 relative to the translation frame 12 along the synchronous belt 4132.

[0053] The first driving motor 4133 drives the synchronous wheels 4131 to rotate, so that the synchronous belt 4132 sleeved on the synchronous wheels 4131 can slide relative to the first sliding rail 411, thereby achieving the driving effect on the sliding plate 412.

[0054] Further, the number of the first sliding 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 device.

[0055] Further, the number of the first driving parts 413 in the device is two, and the two first driving motors 4133 synchronously drive the two synchronous wheels 4131 to rotate, which can improve the stability of the device and the efficiency of carrying heavy objects. Here, the synchronous wheels 4131, the synchronous belt 4132, and the first driving motor 4133 are all common and easily purchased devices on the market, which are conventional settings known to those skilled in the art and will not be described in detail here.

[0056] In the embodiment, as shown in Figures 4 to 6 The clamping unit 42 includes two clamping plates 421, two abutting blocks 422, at least one second driving part 423, and two suction cups 424.

The fixed end of the second driving part is connected to the fixed seat 51, and the movable end is connected to the clamping plate 421, for driving the two clamping plates 421 to rotate towards or away from each other, so as to clamp or release the material.

[0058] The two clamping plates 421 can rotate relative to the fixed seat 51 under the drive of the second driving part 423, so as to clamp or release the material. The abutting part is elastic, which can improve the stability of the device in clamping the material.

[0059] Further, the clamping unit 42 further comprises a parallelogram linkage 425, and the clamping plate 421 and the movable end of the second driving part 423 are rotationally connected through the parallelogram linkage 425, which can improve the stability of the rotation of the device.

[0060] Further, the second driving part 423 is a common rudder on the market and easy to purchase, which is a conventional arrangement known to those skilled in the art, and will not be described in detail here.

[0061] In one embodiment, as shown in Figures 4 to 6 , two suction cups 424 are arranged relative to the material and connected to the two clamping plates 421 respectively. The suction cup 424 can generate a negative pressure adsorption force to adsorb the material.

[0062] The suction cup 424 and the clamping plate 421 together constitute the clamping unit 42, which can increase the crane gripper type and improve the adaptability to goods of different shapes and different materials.

[0063] Further, the suction cup 424 is connected to the negative pressure vacuum pump through the connecting pipe. The negative pressure generated by the negative pressure vacuum pump can remove the air between the suction cup 424 and the object and form a negative pressure vacuum space, thereby forming an adsorption force for sucking up the material. The suction cup 424 and the negative pressure vacuum pump are common and easy to purchase on the market, which are conventional arrangements known to those skilled in the art, and will not be described in detail here.

[0064] In one embodiment, as shown in Figure 1 , Figure 7 The width of the limiting plate 33 is less than the minimum distance between the two suction cups 424 when clamping the material, so that after the two suction cups 424 suck up the material, the limiting plate 33 can pass through the gap between the two suction cups 424, thereby avoiding interference of the limiting plate 33 with the clamping or releasing of the material by the suction cup 424.

[0065] Further, a waist round groove is formed in the limiting plate 33, which penetrates the limiting plate 33. When the materials are stacked, the small-diameter material can pass through the waist round groove when the two clamping plates 421 clamp the small-diameter material, and the small-diameter material is stacked on the bottom support 31, thereby avoiding interference of the limiting plate 33 with the clamping or releasing of the material by the clamping plate 421. Further description will not be made here.

[0066] In one embodiment, the fixed base 51 is disposed below the sliding plate 412 and can slide relative to the sliding plate 412. The clamping unit 42 is movably connected to the fixed base 51. The first linear drive member 52 has a fixed end and a telescopic end. The fixed end of the first linear drive member 52 is connected to the sliding plate 412 and the telescopic end is connected to the fixed base 51, which is used to drive the fixed base 51 and the clamping unit 42 to rise and fall relative to the sliding plate 412.

[0067] The fixed base 51 is used to support and connect the two clamping plates 421 and to enable the lifting and lowering between the relative sliding plates 412.

[0068] Furthermore, such as Figures 4 to 6 As shown, the first linear drive component 52 includes a lifting ring 521, a guide pulley 522, a winding wheel 523, a steel wire rope, and a second drive motor 525. The lifting ring 521 is connected to the fixed base 51 and can pass through the sliding plate 412. The second drive motor 525 is connected to the sliding plate 412. The steel wire is wound around 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 drive motor 525 is coaxially arranged with the winding wheel 523. When the winding wheel 523 rotates, it can drive the fixed base 51 to rise and fall relative to the sliding plate 412. The lifting ring 521, guide pulley 522, winding wheel 523, steel wire rope, and second drive motor 525 are all common and readily available equipment on the market and are conventional settings known to those skilled in the art. They will not be described in detail here.

[0069] In one embodiment, such as Figures 4 to 6 As shown, the sliding plate 412 has guide holes, and the guide shaft 53 is set in a one-to-one correspondence with the guide holes. One end of the guide shaft 53 is connected to the fixed base 51, and the other end is slidably inserted into the guide hole.

[0070] The guide hole and guide shaft 53 work together to improve stability during the lifting process.

[0071] Furthermore, there are two guide shafts 53 here, which are spaced apart from each other and are both connected to the fixed base 51.
