Description

Technical Field

[0001] This application belongs to the field of material handling technology, specifically relating to a fixed pneumatic double-arm handling device. Background Technology

[0002] In the field of material handling technology, it is often necessary to move materials between fixed workstations and surrounding areas, especially in fixed work points such as painting and assembly in mechanical manufacturing workshops, which often involve the movement of heavy objects such as H-frames and steel pipes.

[0003] Currently, in space-constrained areas such as paint booths, there is a general lack of dedicated material handling equipment. Material handling mainly relies on manual lifting and moving by workers, with multiple people working together to move and flip the materials.

[0004] However, this manual handling method has obvious drawbacks: First, the handling efficiency is low, and each material adjustment requires the cooperation of multiple people, which takes too long; second, there are high safety risks, as heavy objects can easily cause injury to personnel during handling; third, due to the manual operation mode, it is difficult to achieve large-scale, high-efficiency material handling centered on a fixed point in a small space, which seriously restricts the improvement of work efficiency. Summary of the Invention

[0005] This application provides a fixed pneumatic double-arm handling device to solve the technical problems of low efficiency, high operational risk and lack of dedicated equipment in the prior art when relying on manual handling of heavy materials in confined spaces.

[0006] To achieve the above objectives, this application provides a fixed pneumatic double-arm conveying device, comprising:

[0012] The platform has at least a first working position and a second working position.

[0013] The distance between the support platform and the column is equal to the sum of the extension lengths of the first swing arm assembly and the second swing arm assembly, and the support platform is in the first working position when the distance between the support platform and the column reaches its maximum value.

[0014] When the first swing arm assembly and the second swing arm assembly form the minimum working angle, and the distance between the support platform and the column reaches the minimum value, the support platform is located in the second working position.

[0015] Preferably, the first swing arm assembly includes: a first swing arm, a second swing arm, and a first connecting plate;

[0022] The third rotating arm at the other end away from the first rotating arm and the fourth rotating arm at the other end away from the second rotating arm are connected by a second connecting plate.

[0023] Preferably, the second boom assembly and the lifting cylinder are connected via a pitch drive assembly; the pitch drive assembly includes a pitch cylinder and a connecting beam.

[0024] The cylinder body of the pitch cylinder is rotatably connected to the lower end of the second connecting plate;

[0025] One end of the connecting beam is rotatably connected to the upper end of the second connecting plate, the other end of the connecting beam away from the second connecting plate is rotatably connected to the piston rod end of the lifting cylinder, and the middle part of the connecting beam is connected to the piston rod end of the pitching cylinder away from the second connecting plate.

[0026] The connecting beam moves in pitch with the connection point between the connecting beam and the second connecting plate as the fulcrum.

[0027] Preferably, it also includes a handle, which is disposed on the cylinder body of the lifting cylinder.

This application enables the carrying platform to change between its maximum and minimum radial positions through the coordinated movement of the first and second rotating arm assemblies, thereby realizing large-scale material handling centered on a fixed column and effectively solving the technical problems of low efficiency and high safety risks in manual handling in the prior art.

[0041] The embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described below do not represent all embodiments consistent with this application. They are merely examples of systems and methods consistent with some aspects of this application.

[0042] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0043] The terms "first," "second," "third," etc., are used to distinguish similar or related objects or entities, and do not necessarily imply a specific order or sequence, unless otherwise specified. It should be understood that such terms can be used interchangeably where appropriate.

[0044] The terms “comprising” and “having”, and any variations thereof, are intended to cover but not exclusively include, for example, a product or device that includes a range of components is not necessarily limited to all of the components that are clearly listed, but may include other components that are not clearly listed or that are inherent to such product or device.

[0045] In the field of material handling technology, existing devices for material turnover at fixed workstations often suffer from problems such as large structure, large space occupation, and inability to adapt to confined work areas. These handling devices typically employ fixed booms or large robotic arms, which struggle to achieve effective material handling in space-constrained environments such as paint booths. When the equipment is too large, it cannot be installed and used in limited spaces; when the equipment's operating range is too small, it cannot meet actual handling needs. This results in on-site operations still relying primarily on manual handling, which not only increases labor intensity and operational risks but also affects overall work progress due to low handling efficiency, thus hindering the improvement of production efficiency.

[0046] To address the aforementioned problems, this application provides a fixed pneumatic double-arm conveying device, see attached... Figure 1 - Figure 3 It includes: column 1, first swing arm assembly 2, second swing arm assembly 3, lifting cylinder 4 and bearing platform 5.

[0047] Column 1 is the fixed foundation of the device. Column 1 is firmly connected to the ground through its bottom, providing stable support for the entire handling device.

[0048] The first rotating arm assembly 2 extends radially away from the vertical axis of the column 1. The first rotating arm assembly 2 is rotatably connected to the end of the column 1 away from the ground. The first rotating arm assembly 2 can rotate around the vertical axis of the column 1. By rotating the first rotating arm assembly 2, the second rotating arm assembly 3 connected to it and the bearing platform 5 at the end are driven to move in a circle around the column 1.

[0049] The second rotating arm assembly 3 is rotatably connected to the end of the first rotating arm assembly 2 away from the column 1. The second rotating arm assembly 3 can rotate around the end of the first rotating arm assembly 2. Through the coordinated movement of the first rotating arm assembly 2 and the second rotating arm assembly 3, the working radius of the bearing platform 5 is changed, and the bearing platform 5 is positioned at different working radii.

[0050] The second rotating arm assembly 3, located away from the first rotating arm assembly 2, is connected to a lifting cylinder 4. The lifting cylinder 4 extends towards the ground, and its cylinder body, located away from the second rotating arm assembly 3, is connected to the support platform 5. The lifting cylinder 4 drives the support platform 5 to move up and down through the extension and retraction of its piston rod, thereby enabling the lifting and lowering of the support platform 5 and completing the material picking and placing operations.

[0051] The support platform 5 is a component that supports materials to be transported. The support platform 5 has at least a first working position and a second working position. The first working position and the second working position are achieved through the relative positional relationship between the first rotating arm assembly 2 and the second rotating arm assembly 3.

[0052] The distance between the support platform 5 and the column 1 is equal to the sum of the extension lengths of the first swing arm assembly 2 and the second swing arm assembly 3. When the distance between the support platform 5 and the column 1 reaches its maximum value, the support platform 5 is in the first working position. The first working position is suitable for moving materials from the material storage area in the paint booth to a more distant paint operation area, meeting the needs of large-scale material handling.

[0053] When the first rotating arm assembly 2 and the second rotating arm assembly 3 form a minimum working angle, and the distance between the carrying platform 5 and the column 1 reaches its minimum value, the carrying platform 5 is in the second working position. The minimum working angle ranges from 25 degrees to 45 degrees. The second working position is suitable for scenarios where the material storage area in a paint booth is confined, enabling material grabbing within a limited space and minimizing space occupation when the device is in standby mode.

[0054] It should be noted that during operation of the handling device, the operator coordinates the operation of the first rotating arm assembly 2 and the second rotating arm assembly 3. The first rotating arm assembly 2 rotates around the column 1, driving the second rotating arm assembly 3 and the end effector to perform circular motion. The second rotating arm assembly 3 rotates relative to the first rotating arm assembly 2, changing the extension length of the entire rotating arm assembly structure. By adjusting the rotation angles of the first rotating arm assembly 2 and the second rotating arm assembly 3 respectively, the operator can move the carrying platform 5 within the working area centered on the column 1.

[0055] Once the support platform 5 is positioned directly above the material, the lifting cylinder 4 activates, lowering the support platform 5 until it contacts the material. After the support platform 5 stably supports the material, the lifting cylinder 4 retracts, raising the material to a safe transport height. The operator then operates the first rotating arm assembly 2 and the second rotating arm assembly 3 again to transport the material to the target location. Upon reaching the target point, the lifting cylinder 4 extends, causing the material to descend along with the support platform 5 until it is placed. After placement, the lifting cylinder 4 retracts, separating the support platform 5 from the material, and the equipment prepares for the next work cycle.

[0056] When materials need to be moved to the working point furthest from column 1, the operator adjusts the carrying platform 5 to the first working position. At this time, the distance between the carrying platform 5 and column 1 is equal to the sum of the extension lengths of the first swing arm assembly 2 and the second swing arm assembly 3. When working in a confined space or when the equipment is in standby mode, the operator adjusts the carrying platform 5 to the second working position. At this time, the first swing arm assembly 2 and the second swing arm assembly 3 form the minimum working angle, and the distance between the carrying platform 5 and column 1 reaches its minimum value.

[0057] As can be seen from the above technical solution, the fixed pneumatic double-arm handling device provided in this embodiment, through the fixed installation of the column 1 and the coordinated movement of the first arm assembly 2 and the second arm assembly 3, realizes a large-scale material handling based on a single fixed point. When the distance between the carrying platform 5 and the column 1 is equal to the sum of the extension lengths of the first arm assembly 2 and the second arm assembly 3, the carrying platform 5 is located in the first working position, achieving the maximum working range. When the first arm assembly 2 and the second arm assembly 3 form the minimum working angle, the carrying platform 5 is located in the second working position, achieving the minimum space occupation. Mechanized handling replaces manual operation, eliminating the safety hazards of heavy object handling. The coordinated movement of the first arm assembly 2 and the second arm assembly 3 ensures the smooth movement of the carrying platform 5, and the operation of the lifting cylinder 4 ensures the safe lifting and lowering of materials. This handling device is easy to operate and effectively improves the material handling efficiency and operational safety level in confined spaces.

[0058] In some embodiments, see Appendix Figure 1 The first rotating arm assembly 2 includes a first rotating arm 21, a second rotating arm 22, and a first connecting plate 23. The first rotating arm 21 is rotatably mounted on the top of the column 1. The second rotating arm 22 is rotatably mounted on the side wall of the column 1, and is located below the first rotating arm 21. The end of the first rotating arm 21 away from the column 1 and the end of the second rotating arm 22 away from the column 1 are connected by the first connecting plate 23.

[0059] The first rotating arm 21 is connected to the top of the column 1 via a rolling bearing. The rolling bearing is installed in a bearing housing at the top of the column 1. The end of the first rotating arm 21 closest to the column 1 is connected to the inner ring of the rolling bearing via a connecting shaft, allowing the first rotating arm 21 to rotate around the vertical axis of the column 1.

[0060] The second rotating arm 22 is connected to the side wall of the column 1 via a rolling bearing. The bearing housing of the rolling bearing is fixed to the side wall of the column 1. The end of the second rotating arm 22 closest to the column 1 is connected to the inner ring of the rolling bearing via a connecting shaft, allowing the second rotating arm 22 to rotate around the vertical axis of the column 1. The second rotating arm 22 is located below the first rotating arm 21, and the first rotating arm 21 and the second rotating arm 22 are spaced apart in the vertical direction. The first connecting plate 23 is fixedly connected to the end of the first rotating arm 21 away from the column 1, and at the same time, the first connecting plate 23 is fixedly connected to the end of the second rotating arm 22 away from the column 1, so that the first rotating arm 21, the second rotating arm 22, and the first connecting plate 23 together form a stable support structure.

[0061] It should be noted that, apart from rolling bearings, the first rotating arm 21 and the column 1, as well as the second rotating arm 22 and the column 1, can be connected by pivots, spherical bearings, or other connection structures that enable relative rotation.

[0062] Understandably, during actual operation, when the operator pushes the first rotating arm assembly 2, the first rotating arm 21 and the second rotating arm 22 achieve synchronous rotation around the axis of the column 1 through the rigid frame formed by the first connecting plate 23. The first rotating arm 21 rotates around the top of the column 1, and the second rotating arm 22 rotates around the side wall of the column 1. Due to the rigid connection of the first connecting plate 23, the first rotating arm 21 and the second rotating arm 22 maintain a fixed relative position and parallel relationship during rotation, thus forming a stable and synchronous motion system.

[0063] In this embodiment, a stable three-dimensional support structure is constructed by intermittently positioning a first rotating arm 21 and a second rotating arm 22 at the top and sidewall of the column 1, combined with a rigid connection via a first connecting plate 23. The first and second rotating arms 21 and 22 maintain synchronous movement during rotation, forming a stable motion system. The arrangement of the first and second rotating arms 21 and 22 improves the overall rigidity and deformation resistance of the first rotating arm assembly 2, enhancing its load-bearing stability. The double-rotating-arm structure of the first and second rotating arms 21 and 22 optimizes load distribution, extends the service life of the rolling bearings, and provides a reliable structural foundation for the handling device.

[0064] In some embodiments, see Appendix Figure 1 The second rotating arm assembly 3 includes a third rotating arm 31, a fourth rotating arm 32, and a second connecting plate 33. The third rotating arm 31 is rotatably disposed at the end of the first rotating arm 21 away from the column 1. The fourth rotating arm 32 is rotatably disposed at the end of the second rotating arm 22 away from the column 1. The other ends of the third rotating arm 31 and the fourth rotating arm 32 are connected by the second connecting plate 33.

[0065] The third rotating arm 31 is connected to the end of the first rotating arm 21 away from the column 1 via a rolling bearing. The rolling bearing is installed in the bearing housing at the end of the first rotating arm 21 away from the column 1. The end of the third rotating arm 31 near the first rotating arm 21 is connected to the inner ring of the rolling bearing via a connecting shaft, so that the third rotating arm 31 can rotate around the end of the first rotating arm 21 away from the column 1.

[0066] The fourth rotating arm 32 is connected to the end of the second rotating arm 22 away from the column 1 via a rolling bearing. The rolling bearing is installed in a bearing housing at the end of the second rotating arm 22 away from the column 1. The end of the fourth rotating arm 32 near the second rotating arm 22 is connected to the inner ring of the rolling bearing via a connecting shaft, so that the fourth rotating arm 32 can rotate around the end of the second rotating arm 22 away from the column 1.

[0067] A fixed distance is maintained between the third rotating arm 31 and the fourth rotating arm 32. The second connecting plate 33 is fixedly connected to the end of the third rotating arm 31 away from the first rotating arm 21, and at the same time, the second connecting plate 33 is fixedly connected to the end of the fourth rotating arm 32 away from the second rotating arm 22, so that the third rotating arm 31, the fourth rotating arm 32 and the second connecting plate 33 together form a stable support structure.

[0068] It should be noted that, apart from rolling bearings, the third rotating arm 31 and the first rotating arm 21, and the fourth rotating arm 32 and the second rotating arm 22, can be connected by pivots, spherical bearings, or other connection structures that enable relative rotation.

[0069] Understandably, during actual operation, when the operator pushes the second rotating arm assembly 3, the third rotating arm 31 and the fourth rotating arm 32 rotate synchronously through the rigid frame formed by the second connecting plate 33. The third rotating arm 31 rotates around the end of the first rotating arm 21 away from the column 1, and the fourth rotating arm 32 rotates around the end of the second rotating arm 22 away from the column 1. Due to the rigid connection of the second connecting plate 33, the third rotating arm 31 and the fourth rotating arm 32 maintain a fixed relative position during rotation, thus forming a stable and synchronous motion system.

[0070] This embodiment constructs a stable three-dimensional support structure through the relative arrangement of the third rotating arm 31 and the fourth rotating arm 32, combined with the rigid connection of the second connecting plate 33. The third rotating arm 31 and the fourth rotating arm 32 maintain synchronous movement during rotation, forming a stable motion system. The relative position of the third rotating arm 31 and the fourth rotating arm 32 improves the overall rigidity and deformation resistance of the second rotating arm assembly 3, enhancing its load-bearing stability. The optimized arrangement of the third rotating arm 31 and the fourth rotating arm 32 optimizes load distribution, extends the service life of the rolling bearings, and provides a reliable structural foundation for the handling device.

[0071] In some embodiments, see Appendix Figure 1 The second boom assembly 3 and the lifting cylinder 4 are connected via a pitch drive assembly 6. The pitch drive assembly 6 includes a pitch cylinder 61 and a connecting beam 62. The cylinder body of the pitch cylinder 61 is rotatably connected to the lower end of the second connecting plate 33. One end of the connecting beam 62 is rotatably connected to the upper end of the second connecting plate 33, the other end of the connecting beam 62 away from the second connecting plate 33 is rotatably connected to the piston rod end of the lifting cylinder 4, and the middle part of the connecting beam 62 is connected to the piston rod end of the pitch cylinder 61 away from the second connecting plate 33. The connecting beam 62 performs pitch movement with the connection point between the connecting beam 62 and the second connecting plate 33 as the fulcrum.

[0072] The cylinder body of the pitch cylinder 61 is rotatably connected to the lower end of the second connecting plate 33 via a pin. The connecting beam 62 is rotatably connected to the upper end of the second connecting plate 33 via a pin. The middle part of the connecting beam 62 is rotatably connected to the piston rod end of the lifting cylinder 4 via a pin. The connecting beam 62 is rotatably connected to the piston rod end of the pitch cylinder 61 via a pin.

[0073] It should be noted that those skilled in the art will understand that any rotatable connection, such as a pin, bearing, or spherical bearing, used to implement this solution falls within the scope of protection of this invention. The choice of specific form depends on a comprehensive consideration of cost, performance, lifespan, and installation accuracy. This embodiment uses a pin connection as an example for illustration, but it should not be construed as a limitation of the invention.

[0074] Understandably, in actual operation, the core function of the pitch drive assembly 6 is to adjust the pitch posture of the support platform 5 and the material to meet the angle requirements of the painting operation. When it is necessary to paint the top of the material or the side facing the operator, the operator controls the piston rod of the pitch cylinder 61 to retract. Through the lever action of the connecting beam 62, the lifting cylinder 4 and the support platform 5 are pulled downward, so that the surface of the material to be painted is at an angle that is convenient for painting. When it is necessary to paint the bottom of the material or the side away from the operator, the operator controls the piston rod of the pitch cylinder 61 to extend, pushing the middle of the connecting beam 62 upward. The connecting beam 62 rotates around the connection point with the second connecting plate 33 as the fulcrum, causing the lifting cylinder 4 and the support platform 5 to tilt upward, so that the bottom of the material faces upward, making it convenient for the operator to carry out the painting operation.

[0075] This embodiment achieves pitch attitude adjustment of the carrying platform 5 and the material through the pitch drive assembly 6. The pitch drive assembly 6 uses a pitch cylinder 61 as its power source. When the piston rod of the pitch cylinder 61 extends or retracts, it drives the connecting beam 62 to rotate around the connection point with the second connecting plate 33, converting the linear extension and retraction motion of the pitch cylinder 61 into the pitch motion of the carrying platform 5, thereby stably driving the material to complete the angle change. The pitch drive assembly 6 effectively solves the core problem of manually turning heavy materials during painting operations, transforming the material angle adjustment work, which originally required multiple people to cooperate, was labor-intensive, and posed safety risks, into a mechanized operation that can be performed by two people, improving the efficiency and safety level of the painting operation.

[0076] In some embodiments, see Appendix Figure 1 The fixed pneumatic double-arm conveying device also includes a handle 7. The handle 7 is located on the cylinder body of the lifting cylinder 4.

[0077] The handle 7 is connected to the outer surface of the cylinder body of the lifting cylinder 4 via a fixed bracket. The fixed bracket includes two semi-circular clamps, which are fastened to the cylinder body of the lifting cylinder 4 by bolts. The handle 7 is fixed to the fixed bracket by threaded connection or welding.

[0078] It should be noted that during actual operation, the operator holds handle 7 to push the conveying device. When the lifting cylinder 4 moves with the second rotating arm assembly 3, handle 7 moves synchronously with the lifting cylinder 4. The operator applies force through handle 7 to control the direction and speed of the entire conveying device.

[0079] In this embodiment, a handle 7 is provided on the cylinder body of the lifting cylinder 4, providing the operator with a direct control point for the conveying device. The handle 7 allows the operator to perform close-range control of the material handling process near the carrying platform 5.

[0080] In some embodiments, see Appendix Figure 1 and Figure 2 The fixed pneumatic double-arm handling device also includes a control valve 8. The control valve 8 is located on the handle 7. The control valve 8 includes a first control valve 81 and a second control valve 82. The first control valve 81 is connected to the lifting cylinder 4. The second control valve 82 is connected to the pitch cylinder 61.

[0081] The first control valve 81 and the second control valve 82 are respectively fixed to both ends of the handle 7. The first control valve 81 is connected to the rodless chamber and the rod chamber of the lifting cylinder 4 through an air passage. The second control valve 82 is connected to the rodless chamber and the rod chamber of the pitch cylinder 61 through an air passage. The control valve 8 is a three-position five-way manual directional valve with a neutral position closing function.

[0082] It should be noted that during actual operation, the operator holds handle 7 with both hands and can operate the first control valve 81 and the second control valve 82 at both ends of handle 7 respectively. When it is necessary to lift or lower the material, the operator operates the control lever of the first control valve 81 to change the airflow direction to the lifting cylinder 4, driving the piston rod of the lifting cylinder 4 to retract or extend, thereby achieving vertical lifting or lowering of the material. When it is necessary to adjust the angle of the material for painting operations on different surfaces, the operator operates the control lever of the second control valve 82 to change the airflow direction to the pitch cylinder 61, driving the piston rod of the pitch cylinder 61 to extend or retract, which, through the connecting beam 62, drives the lifting cylinder 4 and the supporting platform 5 to perform pitching motion, thereby achieving the adjustment of the material's posture.

[0083] In this embodiment, by placing the first control valve 81 and the second control valve 82 at both ends of the handle 7, the operation and control functions of the conveying device are concentrated at the handle 7. While pushing the handle 7 to rotate the first rotating arm assembly 2 and the second rotating arm assembly 3 to move the conveying device, the operator can directly operate the first control valve 81 and the second control valve 82 on the handle 7 to achieve real-time control of material lifting and tilting movements.

[0084] In some embodiments, the fixed pneumatic double-arm conveying device further includes a pneumatic pressure generating device. The pneumatic pressure generating device is connected to the first control valve 81 and the second control valve 82, respectively.

[0085] The air pressure generating device is an air compressor. It is fixedly installed on the ground. The air pressure generating device is connected to the first control valve 81 and the second control valve 82 via a main air pipeline. The main air pipeline runs along the outer wall of the column 1. It is fixed to the outer wall of the column 1 by pipe clamps. Near the control valves 8, the main air pipeline splits into two independent branch pipelines: one branch pipeline connects to the air inlet of the first control valve 81, and the other branch pipeline connects to the air inlet of the second control valve 82.

[0086] It should be noted that during actual operation, the air pressure generating device starts and generates compressed air. The compressed air is delivered through the main air pipeline and simultaneously delivered to the first control valve 81 and the second control valve 82 via two branch pipelines. When the first control valve 81 is operated, the compressed air enters the lifting cylinder 4 through the first control valve 81, driving the piston rod of the lifting cylinder 4 to move. When the second control valve 82 is operated, the compressed air enters the pitch cylinder 61 through the second control valve 82, driving the piston rod of the pitch cylinder 61 to move.

[0087] In this embodiment, a pneumatic power source is provided for the conveying device by setting up a pneumatic pressure generator. The compressed air generated by the pneumatic pressure generator is delivered to the first control valve 81 and the second control valve 82 through air pipelines, providing working power for the lifting cylinder 4 and the pitching cylinder 61. The connection structure between the pneumatic pressure generator, the first control valve 81, and the second control valve 82 forms a complete pneumatic control system, providing power guarantee for the coordinated lifting and pitching movements of the conveying device.

[0088] In some embodiments, the stationary pneumatic double-arm conveying device further includes a pressure sensor. The pressure sensor is connected between the air pressure generator and the control valve 8.

[0089] It should be noted that during actual operation, the pressure sensor continuously monitors the air source pressure output from the air pressure generator to control valve 8. When the air pressure generator starts supplying air, compressed air flows through the pipeline section where the pressure sensor is located, and the pressure sensor converts the gas pressure value into an electrical signal output.

[0090] This embodiment achieves real-time monitoring of the pneumatic system source pressure by installing a pressure sensor in the main air circuit. The pressure sensor enhances the safety and maintainability of the handling device. Continuous monitoring of the system pressure allows for the timely detection of potential pneumatic system faults, preventing performance degradation or operational interruptions due to abnormal pressure, thus ensuring the stable operation of the handling equipment.

[0091] In some embodiments, see Appendix Figure 1 A flange 9 is fixedly installed at the bottom of the column 1. Multiple through holes are opened around its axis on the flange 9. Fasteners pass through the through holes on the flange 9 and are fixedly connected to the ground.

[0092] Flange 9 is a disc-shaped metal component. The center hole of flange 9 mates with the bottom end of column 1. Flange 9 and the bottom of column 1 are fixedly connected by circumferential welding. Multiple through holes on flange 9 are evenly distributed along the circumference. These through holes can be smooth or threaded. Fasteners include anchor bolts or chemical anchors.

[0093] In this embodiment, the installation of the column 1 is made more stable by setting the flange 9. The larger contact area and the arrangement of multiple fixing points effectively improve the anti-overturning ability of the column 1, providing a reliable foundation support for the stable operation of the entire handling device.

[0094] In some embodiments, see Appendix Figure 1 At least one reinforcing rib plate 24 is fixedly connected between the first rotating arm 21 and the second rotating arm 22. The reinforcing rib plate 24 is disposed in the gap between the first rotating arm 21 and the second rotating arm 22. The two ends of the reinforcing rib plate 24 are fixedly connected to the side of the first rotating arm 21 and the side of the second rotating arm 22, respectively. The connection between the reinforcing rib plate 24 and the first rotating arm 21 and the second rotating arm 22 is by welding or bolting.

[0095] In this embodiment, a reinforcing rib 24 is provided between the first rotating arm 21 and the second rotating arm 22, thereby enhancing the structural rigidity of the first rotating arm assembly 2. The connection of the reinforcing rib 24 transforms the first rotating arm 21 and the second rotating arm 22 from independent force-bearing to collaborative force-bearing, improving the overall assembly's resistance to deformation.

The specific implementation methods provided above are only a few examples under the overall concept of this application and do not constitute a limitation on the scope of protection of this application. For those skilled in the art, any other implementation methods extended from the solution of this application without creative effort shall fall within the scope of protection of this application.
