[0056] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0059] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0060] Currently, folding boom cranes feature a two-section articulated boom structure, which folds and extends via hinges and a drive mechanism. The two sections consist of a base boom and a telescopic boom. The base boom is connected to the crane chassis, serving as the supporting foundation for the entire boom. The telescopic boom is hinged to the front end of the base boom and rotates or extends along its axis via a joint.

[0061] However, when faced with a multi-track lifting operation environment, the working range of a two-section folding boom crane cannot meet the lifting requirements due to the limited boom length, rotation angle, and movement dimension of the two sections.

[0062] To address the aforementioned issues, this application provides a gantry crane that expands the operating range, allows for flexible adjustment of the operating angle, and enables the transport of materials to suitable locations to adapt to more complex operating environments.

[0063] like Figure 1-4 and Figure 8 , Figure 9 As shown in an illustrative embodiment of the articulated boom gantry crane of this utility model, the articulated boom gantry crane is used for transporting materials and includes:

[0064] The main frame mechanism includes an X-axis crossbeam 1, a Y-axis crossbeam 2, and a power assembly 6. The X-axis crossbeam 1 and the Y-axis crossbeam 2 are perpendicular to each other and connected. The power assembly 6 connects the X-axis crossbeam 1 and the Y-axis crossbeam 2 and drives the Y-axis crossbeam 2 to move horizontally along the length of the X-axis crossbeam 1.

[0065] One or more X-axis crossbeams 1 can be provided. X-axis crossbeams 1 and Y-axis crossbeams 2 can be configured as a cross or an I-shape. When X-axis crossbeams 1 and Y-axis crossbeams 2 form an I-shape, one X-axis crossbeam 1 is connected to each end of the Y-axis crossbeam 2.

[0066] Multiple columns 19 and multiple diagonal supports 18 are installed on one side of the X-axis crossbeam 1. The columns 19 are spaced equidistantly on the same side of any X-axis crossbeam 1. One end of each column 19 is connected to the X-axis crossbeam 1, and the other end is connected to the mounting plane of the articulated boom gantry crane. One end of each diagonal support 18 is connected to a column 19, and the other end is connected to the mounting plane of the articulated boom gantry crane. The columns 19, diagonal supports 18, and the mounting plane of the articulated boom gantry crane together form a triangular structure, enhancing its stability and making the articulated boom gantry crane installation more secure.

[0067] The power assembly 6 includes a motor 27 and a reducer 28 for providing power during the horizontal movement of the Y-axis crossbeam 2 along the length of the X-axis crossbeam 1.

[0068] The power assembly 6 also includes a traveling unit 21 located on both sides of the Y-axis crossbeam 2, which connects the Y-axis crossbeam 2 and the X-axis crossbeam 1 respectively. The traveling unit 21 positions the Y-axis crossbeam 2 between the X-axis crossbeam 1. The traveling unit 21 includes rollers and roller fixing components. The rollers roll on the X-axis crossbeam 1, driving the Y-axis crossbeam 2 to move horizontally along the length of the X-axis crossbeam 1. The roller fixing components are located between the rollers and the Y-axis crossbeam 2, used to fix the rollers to both ends of the Y-axis crossbeam 2.

[0069] The Y-axis crossbeam 2 can be configured as two parallel straight rods, with multiple crossbeam bracing frames 20 set between the two straight rods. One end of any crossbeam bracing frame 20 is connected to a straight rod, and the other end is connected to another straight rod, providing support for the Y-axis crossbeam 2 and making the structure of the Y-axis crossbeam 2 more stable.

[0070] The moving mechanism 3 includes a moving body 25, a Y-axis transmission assembly 30, and a conveyor belt 7. The moving body 25 is connected to the Y-axis transmission assembly. The conveyor belt 7 is arranged around the Y-axis of the crossbeam 2 along its length. The Y-axis transmission assembly is connected to the conveyor belt 7 and drives the moving body 25 to move horizontally along the Y-axis of the crossbeam 2 on the transmission belt.

[0071] The moving mechanism 3 also includes a rotational power assembly 26, located within the moving vehicle body 25, for providing power for the rotation of the moving vehicle body 25.

[0072] The moving mechanism 3 also includes a drive wheel 31 located on the periphery of the moving vehicle body 25, used to drive the moving mechanism 3 to move.

[0073] The moving mechanism 3 also includes multiple guide wheels 32 located around the periphery of the moving body 25 and close to the drive wheels 31. During the displacement of the moving body 25 on the Y-axis transmission assembly, when the moving body 25 deviates, the guide wheels 32 contact the Y-axis crossbeam, correcting the displacement direction of the moving body 25 and playing a guiding role.

[0074] The articulated boom mechanism 4 includes an upper articulated boom assembly, a middle articulated boom assembly, and a lower articulated boom assembly, which are connected sequentially. The end of the upper articulated boom assembly away from the middle articulated boom assembly is connected to the moving mechanism 3, and the end of the lower articulated boom assembly away from the middle articulated boom assembly is provided with a suction device 5 for suctioning materials.

[0075] The power component 6 in the main frame mechanism drives the Y-axis crossbeam 2 to move horizontally along the length of the X-axis crossbeam 1, thereby adjusting the crane's position in the X-axis direction. The Y-axis transmission component 30 of the moving mechanism 3 drives the moving car body 25 to move horizontally along the length of the Y-axis crossbeam 2 on the conveyor belt 7, completing the crane's position change in the Y-axis direction. The upper, middle, and lower articulated boom components of the boom mechanism 4 fold or extend, thereby adjusting the crane's position in the Z-axis direction. After the suction device 5 picks up the material, the material is transported through the coordination of these mechanisms.

[0076] Through the coordinated operation of the main frame mechanism, the moving mechanism 3, the articulated boom mechanism 4, and the suction device 5, this articulated boom gantry crane can move flexibly in multiple directions and adjust the working range by extending and retracting the articulated boom, thus achieving efficient material transportation and making it suitable for a variety of complex material transportation scenarios.

[0077] like Figure 10 As shown, the moving mechanism 3 also includes a slewing support unit 57, which includes an inner ring, an outer ring, rolling elements, and a spacer block. The slewing support unit 57 can be configured as a single-row four-point contact ball slewing support, a single-row crossed roller slewing support, a double-row unequal-diameter ball slewing support, or a three-row roller slewing support. The slewing support unit 57 is used to support the rotation of the moving mechanism 3.

[0078] In some embodiments, the upper curved arm assembly further includes:

[0079] The fixed base 8 is a rotary support unit connected to the moving mechanism 3, and has a first fixed shaft 49 and a second fixed shaft that are parallel to each other.

[0080] The first straight rod assembly 10 has its first end connected to the first fixed shaft 49 of the fixed seat 8.

[0081] The first straight rod assembly 10 includes two parallel straight rods and a plurality of reinforcing rods. The plurality of reinforcing rods are arranged side by side between the two parallel straight rods, and the two ends of any reinforcing rod are respectively connected to the two parallel straight rods.

[0082] The upper articulated arm connecting box 11 has a built-in third fixed shaft 50 and a fourth fixed shaft that are parallel to each other. The second end of the first straight rod assembly 10 is connected to the third fixed shaft 50 of the fixed seat 8.

[0083] The second straight rod assembly 9 is parallel to the first straight rod assembly 10. The first end of the second straight rod assembly 9 is connected to the second fixed shaft, and the second end is connected to the fourth fixed shaft.

[0084] The second straight rod assembly 9 includes two straight rods that are parallel to each other.

[0085] The first fixed shaft 49 is parallel to the third fixed shaft 50. The first fixed shaft 49, the second fixed shaft, the third fixed shaft 50, the fourth fixed shaft, the first straight rod assembly 10, and the second straight rod assembly 9 together form a parallelogram mechanism.

[0086] The first fixed shaft 49 and the third fixed shaft 50 respectively pass through the two ends of two parallel straight rods in the first straight rod assembly 10. The second fixed shaft and the fourth fixed shaft respectively pass through the two ends of two parallel straight rods in the second straight rod assembly 9. The first straight rod assembly 10 and the second straight rod assembly 9 are fixed between the fixed base 8 and the upper curved arm connecting box 11, together forming a parallelogram-shaped upper curved arm assembly, ensuring that the upper curved arm connecting box 11 is parallel to the fixed base 8.

[0087] The fixed base 8 of the upper articulated boom assembly is connected to the slewing support unit of the moving mechanism 3, providing a stable mounting foundation for the upper articulated boom assembly. The slewing support unit drives the upper articulated boom assembly to adjust its angle. The first fixed shaft 49 passes through the first end of the first straight rod assembly 10, connecting the first straight rod assembly 10 to the fixed base 8. The third fixed shaft 50 passes through the second end of the first straight rod assembly 10, connecting it to the upper articulated boom connecting box 11. The second fixed shaft passes through the first end of the second straight rod assembly 9, and the fourth fixed shaft passes through the second end of the second straight rod assembly 9, connecting the two ends of the second straight rod assembly 9 to the fixed base 8 and the upper articulated boom connecting box 11, respectively.

[0088] Through the layout of multiple fixed axes and the connection of components, the stability and reliability of the upper boom assembly during the movement are ensured, enabling the boom mechanism 4 to perform telescopic movements more accurately and improving the precision of crane operation.

[0089] In some embodiments, the upper articulated arm connecting box 11 houses a fifth fixed shaft 51 and a sixth fixed shaft 52 that are parallel to each other, and the middle articulated arm assembly further includes:

[0090] The third straight rod assembly 13 has its first end connected to the fifth fixed shaft 51.

[0091] The third straight rod assembly 13 includes two parallel straight rods and multiple reinforcing rods. The multiple reinforcing rods are arranged side by side between the two parallel straight rods, and the two ends of any reinforcing rod are respectively connected to the two parallel straight rods.

[0092] The middle articulated boom connecting box 14 has a built-in seventh fixed shaft 53 and an eighth fixed shaft 54 ​​that are parallel to each other, and the second end of the third straight rod assembly 13 is connected to the seventh fixed shaft 53.

[0093] The fourth straight rod assembly 12 is parallel to the third straight rod assembly 13. The first end of the fourth straight rod assembly 12 is connected to the sixth fixed shaft 52, and the second end is connected to the eighth fixed shaft 54.

[0094] The fourth straight rod assembly 12 includes two parallel straight rods.

[0095] Among them, the fifth fixed shaft 51 is parallel to the seventh fixed shaft 53, and the fifth fixed shaft 51, the sixth fixed shaft 52, the seventh fixed shaft 53, the eighth fixed shaft 54, the third straight rod assembly 13 and the fourth straight rod assembly 12 together form a parallelogram mechanism.

[0096] The fifth fixed shaft 51 and the seventh fixed shaft 53 pass through the two ends of two parallel straight rods in the third straight rod assembly 13, respectively. The sixth fixed shaft 52 and the eighth fixed shaft 54 ​​pass through the two ends of two parallel straight rods in the fourth straight rod assembly 12, respectively. The third straight rod assembly 13 and the fourth straight rod assembly 12 are fixed between the middle curved arm connecting box 14 and the upper curved arm connecting box 11, together forming a parallelogram-shaped middle curved arm assembly, ensuring that the middle curved arm connecting box 14 and the upper curved arm connecting box 11 are parallel.

[0097] The third straight rod assembly 13 of the middle articulated boom assembly is connected to the upper articulated boom connecting box 11 via the fifth fixed shaft 51, and the middle articulated boom connecting box 14 is connected to the second end of the third straight rod assembly 13 via the seventh fixed shaft 53. The fourth straight rod assembly 12 is connected to the upper articulated boom connecting box 11 and the middle articulated boom connecting box 14 via the sixth fixed shaft 52 and the eighth fixed shaft 54, respectively. During the extension and retraction of the articulated boom mechanism 4, each component rotates around the fixed shaft and works in coordination with the upper articulated boom assembly to achieve smooth extension and retraction of the articulated boom mechanism 4.

[0098] The structural composition and connection relationships of the middle articulated boom assembly further improve the structural system of the articulated boom mechanism 4. This structural design allows the middle articulated boom assembly to work closely with the upper and lower articulated boom assemblies, enhancing the overall rigidity and stability of the articulated boom mechanism 4 and improving the crane's operational capabilities under complex working conditions.

[0099] In some embodiments, in the upper curved arm connecting box, the third fixed shaft 50 and the fifth fixed shaft 51 are parallel to each other and arranged side by side. Gears 48 are respectively installed on the third fixed shaft 50 and the fifth fixed shaft 51, and the two gears 48 mesh and rotate synchronously, driving the upper curved arm assembly and the middle curved arm assembly to rotate synchronously around the upper curved arm connecting box.

[0100] Furthermore, in the upper articulated arm connecting box 11, gears 48 are respectively provided on both sides of the third fixed shaft 50 and both sides of the fifth fixed shaft 51, and the gears 48 located on the same side mesh with each other. When the articulated arm mechanism 4 extends or retracts, the meshing transmission of the gears 48 can ensure the synchronicity of movement between the upper articulated arm assembly and the middle articulated arm assembly, so that the first straight rod assembly 10 and the third straight rod assembly 13 extend and retract in tandem according to a predetermined trajectory.

[0101] The gear 48 effectively ensures the consistency of movement between the upper and middle articulated boom assemblies, avoids interference between components, improves the transmission efficiency and telescopic accuracy of the articulated boom mechanism 4, and makes the crane more stable and reliable during material transportation.

[0102] In some embodiments, the middle articulated boom connecting box 14 contains a ninth fixed shaft 55 and a tenth fixed shaft 56 that are parallel to each other, and the lower articulated boom assembly further includes:

[0103] The fifth straight rod assembly 16 has its first end connected to the ninth fixed shaft 55.

[0104] The lower curved arm connecting seat 17 is connected to the suction device 5 at the bottom, and has an internal eleventh fixed shaft and a twelfth fixed shaft that are parallel to each other. The second end of the fifth straight rod assembly 16 is connected to the eleventh fixed shaft.

[0105] The lower curved arm connecting seat 17 is connected to the suction device 5 by bolts.

[0106] The sixth straight rod assembly 15 is parallel to the fifth straight rod assembly 16. The first end of the sixth straight rod assembly 16 is connected to the tenth fixed shaft 56, and the second end is connected to the twelfth fixed shaft.

[0107] Among them, the ninth fixed shaft 55 is parallel to the eleventh fixed shaft, and the ninth fixed shaft 55, the tenth fixed shaft 56, the eleventh fixed shaft, the twelfth fixed shaft, the fifth straight rod assembly 16 and the sixth straight rod assembly 15 together form a parallelogram mechanism.

[0108] The ninth fixed shaft 55 and the eleventh fixed shaft pass through the two ends of two parallel straight rods in the fifth straight rod assembly 16, respectively. The tenth fixed shaft 56 and the twelfth fixed shaft pass through the two ends of two parallel straight rods in the sixth straight rod assembly 15, respectively. The fifth straight rod assembly 16 and the sixth straight rod assembly 15 are fixed between the middle curved arm connecting box 14 and the lower curved arm connecting seat 17, together forming a parallelogram-shaped lower curved arm assembly, ensuring that the middle curved arm connecting box 14 and the lower curved arm connecting seat 17 are parallel.

[0109] The fifth straight rod assembly 16 of the lower curved arm assembly is connected to the middle curved arm connecting box 14 via the ninth fixed shaft 55, and the lower curved arm connecting seat 17 is connected to the second end of the fifth straight rod assembly 16 via the eleventh fixed shaft. The sixth straight rod assembly 15 is connected to the middle curved arm connecting box 14 and the lower curved arm connecting seat 17 via the tenth fixed shaft 56 and the twelfth fixed shaft, respectively. The lower curved arm assembly works in conjunction with the upper curved arm assembly and the middle curved arm assembly to realize the telescopic movement of the curved arm mechanism 4.

[0110] The rational design of the lower articulated boom assembly enables the articulated boom mechanism 4 to achieve a wider range of extension and angle adjustment, further expanding the crane's operating range and meeting the material transportation needs at different heights and distances.

[0111] In some embodiments, such as Figure 6 As shown, in the middle curved arm connecting box 14, the seventh fixed shaft 53 and the ninth fixed shaft 55 are parallel to each other and arranged side by side. Gears 48 are respectively installed on the seventh fixed shaft 53 and the ninth fixed shaft 55. The two gears 48 mesh and rotate synchronously, driving the middle curved arm assembly and the lower curved arm assembly to rotate synchronously around the middle curved arm connecting box 14.

[0112] Furthermore, in the middle articulated arm connecting box 14, gears 48 are respectively arranged on both sides of the seventh fixed shaft 53 and both sides of the ninth fixed shaft 55, and the gears 48 located on the same side mesh with each other. When the articulated arm mechanism 4 extends and retracts, these gears 48 ensure the synchronous movement between the middle articulated arm assembly and the lower articulated arm assembly, and enable the third straight rod assembly 13 and the fifth straight rod assembly 16 to extend and retract in coordination, ensuring the overall coordination of the movement of the articulated arm mechanism 4.

[0113] The setting of gear 48 further enhances the synchronization and stability of the movement between the middle and lower articulated boom assemblies, improves the overall working efficiency and reliability of the articulated boom mechanism 4, reduces the risk of failure caused by asynchronous movement of components, and ensures the normal operation of the crane.

[0114] In the articulated boom mechanism 4, the fixed seat 8, the first straight rod assembly 10, the upper articulated boom connecting box 11, and the second straight rod assembly 9 form a parallelogram. The upper articulated boom connecting box 11, the third straight rod assembly 13, the middle articulated boom connecting box 14, and the fourth straight rod assembly 12 form a parallelogram. The middle articulated boom connecting box 14, the fifth straight rod assembly 16, the sixth straight rod assembly 15, and the lower articulated boom connecting seat 17 form a parallelogram. Through multiple parallelogram structures, the upper articulated boom connecting box 11 is parallel to the fixed seat 8, the middle articulated boom connecting box 14 is parallel to the upper articulated boom connecting box 11, and the lower articulated boom connecting seat 17 is parallel to the middle articulated boom connecting box 14, thereby achieving parallelism between the lower articulated boom connecting seat 17 and the fixed seat 8.

[0115] In the upper articulated arm connecting box 11, gears 48 are provided on both sides of the third fixed shaft 50 and both sides of the fifth fixed shaft 51. In the middle articulated arm connecting box 14, gears 48 are provided on both sides of the seventh fixed shaft 53 and both sides of the ninth fixed shaft 55. Adjacent gears 48 mesh with each other and rotate simultaneously, driving the first straight rod assembly 10 unit, the third straight rod assembly 13 unit, and the fifth straight rod assembly 16 unit to maintain synchronous movement. The second straight rod assembly 9, the fourth straight rod assembly 12, and the sixth straight rod assembly 15 move accordingly, further enhancing the stability of the articulated arm mechanism 4.

[0116] Since the fixed seat 8 is in a horizontal state, the lower curved arm connecting seat 17 remains in a horizontal state during the extension and retraction of the curved arm mechanism 4, and the suction device 5 connected to the lower curved arm connecting seat 17 remains in a horizontal state.

[0117] The articulated arm mechanism 4 uses multiple parallelogram structures to keep the fixed seat 8 parallel to the lower articulated arm connecting seat 17, thereby keeping the suction cup 41 connecting assembly parallel and preventing the suction cup 41 from tilting, so that all suction cups 41 can contact the material, better pick up the material surface, and improve the material transportation efficiency.

[0118] In some embodiments, such as Figure 5 As shown, the suction device 5 includes:

[0119] Suction cup 41 is used to pick up materials.

[0120] Main plate 36 connects to the lower articulated arm assembly.

[0121] Multiple mounting holes are provided on both the lower crank arm connecting seat 17 and the main body plate 36. The main body plate 36 and the lower crank arm connecting seat 17 are connected and fixed by bolts passing through the mounting holes on the lower crank arm connecting seat 17 and the main body plate 36.

[0122] The X-axis telescopic arm 37 is connected to the main body plate 36 and has multiple sets of telescopic rods built in, which can extend or shorten along the X-axis.

[0123] The Y-axis telescopic arm 39 is connected to the end of the X-axis telescopic arm 37 away from the main body plate 36, and has multiple sets of telescopic rods built in, which can extend or shorten along the Y-axis.

[0124] Connector 40, one side of any connector 40 is connected to the end of the X-axis telescopic arm 37 or the end of the Y-axis telescopic arm 39, and the other side is connected to the suction cup 41.

[0125] The main body plate 36 connects to the lower curved arm assembly, providing an installation base for the suction device 5. The X-axis telescopic arm 37 has multiple sets of telescopic rods built in, which extend or shorten along the X-axis by extending or shortening the telescopic rods. The Y-axis telescopic arm 39 connects to the end of the X-axis telescopic arm 37 away from the main body plate 36, and also extends or shortens along the Y-axis by extending or shortening the internal telescopic rods. The connector 40 connects the X-axis telescopic arm 37 or the Y-axis telescopic arm 39 to the suction cup 41. By adjusting the extension and retraction of the X and Y axis telescopic arms 39, the position of the suction cup 41 can be precisely controlled, achieving accurate suction and placement of materials.

[0126] The design of the X and Y axis telescopic boom 39 allows the suction cup 41 connecting assembly to be flexibly adjusted in both directions, improving the flexibility and accuracy of the suction device 5, enabling it to adapt to materials of different positions and shapes, and enhancing the crane's adaptability to complex material transportation tasks.

[0127] The suction device 5 can be configured as a 180° rotationally symmetrical structure.

[0128] The suction device 5 also includes an end plate 38 located at the end of the X-axis telescopic arm 37 away from the main body plate 36, and the two ends of the end plate 38 are respectively connected to a Y-axis telescopic arm 39.

[0129] In some embodiments, such as Figure 7 As shown, the moving mechanism 3 also includes a lifting assembly located inside the moving vehicle body 25 and connected to the suction device 5. The lifting assembly includes:

[0130] The drive unit connects to the inside of the moving vehicle body 25.

[0131] Winch 29 connects to the drive unit.

[0132] The traction rope 46 is fixed at one end to the winch 29 and is wound around the winch 29 in the direction of rotation of the winch 29.

[0133] The connecting seat 47 is connected to the other end of the traction rope 46 on one side and to the main body plate 36 on the other side.

[0134] Connector 47 connects to the center of main body plate 36.

[0135] The drive unit of the lifting assembly is connected to the inside of the moving vehicle body 25 and provides power. The winch 29 is connected to the drive unit and rotates under its drive. One end of the traction rope 46 is fixed to the winch 29 and wound around its perimeter, and the other end is connected to the connecting seat 47. When the drive unit is working, it drives the winch 29 to rotate. By winding and unwinding the traction rope 46, the suction device 5 is lifted and lowered, thereby adjusting the height of the suction cup 41 connecting assembly and thus controlling the height of the material.

[0136] The design of the lifting components enables the crane to move materials vertically, enriching the crane's operational functions, expanding its application range, meeting the material transportation needs at different heights, and improving operational efficiency.

[0137] The drive components include a motor 27 and a reducer 28. The motor 27 is connected to the reducer 28.

[0138] The winch assembly 29 includes a winch drum 45, a winch shaft 43, and a mounted bearing 44. One end of the winch shaft 43 is connected to the reducer 28, and the other end is connected to the mounted bearing 44. The winch drum 45 is nested in the middle of the winch shaft 43.

[0139] The traction rope 46 includes a steel wire rope, which is wound around the circumference of the winch drum 45.

[0140] Motor 27 drives winch shaft 43 and winch drum 45 to rotate via reducer 28, thereby winding up and unwinding the wire rope. The wire rope is connected to suction device 5 via connecting seat 47, which in turn drives suction device 5 to rise and fall.

[0141] In some embodiments, the moving mechanism 3 further includes:

[0142] The gas storage tank 35 is located inside the mobile vehicle and is connected to the suction cup 41.

[0143] The moving mechanism 3 also includes a junction box 34, which is connected to the gas storage tank 35.

[0144] The gas tank 35 stores gas to provide a gas source for the operation of the suction cup 41. The junction box 34 is responsible for electrical connections and control. The gas tank 35 is connected to the suction cup 41, and by controlling the pressure of the gas inside the gas tank 35, a stable suction force is provided to the suction cup 41, ensuring that the suction cup 41 can firmly adsorb materials.

[0145] The air tank 35 ensures the stability of the suction force of the suction cup 41, reduces air pressure fluctuations during the operation of the suction cup 41, avoids material falling due to insufficient suction, improves the safety and reliability of material transportation, and also extends the service life of the suction cup 41.

[0146] In some embodiments, cable chain units are provided on the X-axis crossbeam 1, the Y-axis crossbeam 2, and the suction device 5, and each cable chain unit includes a power cable.

[0147] The cable carrier units installed in the X-axis crossbeam 1, Y-axis crossbeam 2, and suction device 5 have internal power cables for transmitting power and signals. During the movement of the crane's various mechanisms, the cable carrier units move along with the mechanisms, protecting the power cables from pulling, abrasion, and entanglement, ensuring stable power and signal transmission.

[0149] A first fixing member 22 is provided on one side of the Y-axis crossbeam 2, which is connected to the first drag chain unit 24 and is used to fix the power cable inside the first drag chain unit 24.

[0150] A second drag chain unit 23 is provided on the Y-axis crossbeam 2, and the second drag chain unit 23 is parallel to the Y-axis crossbeam 2.

[0151] The moving mechanism 3 includes a second fixing member 33, which is connected to the second drag chain unit 23 and is used to fix the power cable inside the second drag chain unit 23.

[0152] A third drag chain unit 42 is provided on the suction device 5, and the third drag chain unit 42 is parallel to the X-axis telescopic arm 37.
