[0036] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0037] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0038] It should be noted that, unless otherwise specified, the experimental methods described in the following implementation plan are all conventional methods, and the reagents and materials described are all commercially available unless otherwise specified.

[0039] In the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The terms "lateral," "longitudinal," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0040] like Figures 1-5 As shown, the scaffolding erection device provided by the present invention includes: a base 1, a main arm 4, a secondary arm 5, and a mechanical claw 7;

[0041] The main arm 4 is rotatably mounted on the base 1, the auxiliary arm 5 is connected to the main arm 4, and the mechanical claw 7 is rotatably connected to the auxiliary arm 5. The mechanical claw 7 is used to clamp the rods and actively drive the rods to form the vertical, horizontal, longitudinal, or inclined state required for erecting the scaffold. The main arm 4 and the auxiliary arm 5 work together to supply the clamped rods to the scaffold erection position.

[0042] refer to Figure 1The base 1 is preferably a movable and walkable base equipped with wheels or tracks, facilitating movement to the area below the scaffolding erection site. A rotatable turntable 2 is mounted on the base 1, and a mounting base 3 is mounted on the turntable 2. The lower end of the main boom 4 is rotatably mounted to the mounting base 3. The main boom can adjust its tilt angle and rotate with the turntable 2 to accommodate construction work in different orientations. Preferably, the main boom is a multi-section telescopic boom, allowing for length adjustment and erection work at different heights. Preferably, the auxiliary boom 5 is a folding boom, foldable relative to the main boom 4. When the auxiliary boom is multi-section, the sections can also fold together, suitable for adjusting the state of the mechanical gripper and adapting to different construction angles. To enable the mechanical gripper 7 to rotate, a rotary drive component 6 is provided at the front end of the auxiliary boom. The rotary drive component 6 is rotatably connected to the mechanical gripper 7, actively driving the mechanical gripper 7 to rotate and change the state of the member. Preferably, the rotary drive component 6 is a hydraulic pump or a motor. Preferably, the mechanical grippers 7 are a pair, simultaneously clamping the steel pipe member.

[0043] When implementing the above solution, the drive base moves below the scaffolding erection position, the drive mechanical claw picks up the steel pipe members, and the control rotation drive component adjusts the steel pipe members to the required vertical, horizontal, longitudinal, or inclined state. The control of the main boom and auxiliary boom feeds the steel pipe members to the erection position, where workers use tools and fasteners to secure them. This implementation method can easily complete the transportation and splicing of steel pipe members, truly solving the problems of high manpower consumption, low efficiency, and high safety hazards in hoisting steel pipes during scaffolding erection.

[0044] Furthermore, the difficulty in scaffolding erection lies in the hoisting of steel pipes and the coordination between the steel pipes and fasteners. Traditional hoisting ropes and hooks are difficult to control the steel pipes and are also difficult to apply force during splicing. In another embodiment of the present invention, the mechanical claw is configured to engage or release the rods through opening and closing actions, which can efficiently grab the steel pipes and effectively control them. It also has an active stroke along the length of the rod. After the steel pipe rods are positioned and aligned with the fasteners, the force is applied to perform the splicing action, allowing the steel pipes to be directly sleeved into the fasteners. This makes it convenient for workers to directly use tools to tighten the fastener bolts, effectively improving the erection efficiency.

[0045] Furthermore, another challenge in scaffolding erection is the positioning and alignment of steel pipes and fasteners. In another embodiment of the present invention, the mechanical claw is designed with a telescopic space in the length direction. When the steel pipe members are fed to the erection position by the main arm and auxiliary arm, the workers use this telescopic space to adjust the steel pipe members to accurately align with the fasteners. When the steel pipe members have not reached the alignment position, they are pulled forward to align with the fasteners. When the steel pipe members have exceeded the alignment position, they are pushed backward to align with the fasteners. The telescopic space design of the mechanical claw provides local adjustment space for the members, enabling efficient and accurate positioning in cooperation with on-site workers. Compared with complex modeling and positioning algorithms, this method is simpler and easier to use. It eliminates the need for the main arm and auxiliary arm to achieve precise positioning, and local precise alignment is completed manually, effectively reducing difficulty, improving efficiency, and adapting to various complex on-site environments. Therefore, it is highly efficient and practical.

[0046] Furthermore, in another embodiment, the telescopic space is specifically an elastic telescopic space, which can provide damping to prevent the clamped steel pipe from colliding hard with the scaffolding.

[0047] Furthermore, to make the positioning of the steel pipe members more convenient and accurate, in another embodiment of the invention, the mechanical gripper is provided with a swing space, allowing the clamped member to locally adjust its position within the swing space to achieve accurate positioning. Compared to the aforementioned telescopic space, the swing space can adjust the position of the member vertically, and in conjunction with the telescopic space, it enables adjustment of the member in multiple spatial dimensions (up, down, left, and right), achieving accuracy and efficiency.

[0048] Furthermore, in another embodiment, the swing space is an elastic swing space, which provides damping to prevent hard collisions caused by excessive swinging.

[0049] Furthermore, such as Figures 2-5 As shown, the present invention provides a mechanical gripper 7 capable of performing a locking action, comprising: a gripper base 70, a slide 9, gripper arms 10, and grippers 11; the slide 9 is slidably disposed on the gripper base 70, a plurality of gripper arms 10 are connected to the slide 9, and the grippers 11 are connected to the gripper arms 10. The grippers 11 are used to clamp the rod, and the slide 9 is driven to linear motion by a driver, thereby driving the clamped rod to perform a locking action through the gripper arms 10 and the grippers 11.

[0050] Figure 2 In the figure, the claw base 70 is provided with a mounting part 16 connected to the rotary drive component 6. Preferably, the claw arms are provided as a pair, and the claws 11 are provided with an opening and closing structure for clamping and releasing the steel pipe rod. The drive is preferably a hydraulic cylinder or an electric telescopic cylinder for linearly driving the slide 9 to move. In the figure, one end of the claw arm 10 is fixed to the slide, and the other end extends outward and is equipped with the claw 11.

[0051] Furthermore, in another embodiment, the claw arm is a telescopic rod structure or a scissor structure, allowing the clamped rod to have room to move forward and backward, thus enabling fine-tuning of its local position. For example... Figure 2 The diagram shows a telescopic rod structure. Alternatively, the two claw arms can be configured as a scissor structure to allow for fine-tuning of the front and rear positions of the clamped steel pipe.

[0052] Furthermore, in another implementation, such as Figure 2 As shown, the claw arm is a freely telescopic arm used to provide localized forward and backward movement. In the illustration, the claw arm is composed of multiple sleeved arm sections, which can easily complete sliding extension and retraction, making operation more convenient for workers.

[0053] Furthermore, in another embodiment, the claw arm is an elastic telescopic arm, which provides elastic telescopic space so that the extension and retraction of the claw arm is damped, thereby playing a buffering role and reducing the risk of hard collision.

[0054] Furthermore, in another implementation, such as Figure 3 As shown, the claw 11 is a non-swinging structure, comprising a top plate 19, a telescopic cylinder 20, a housing 21, and claw teeth 22. The top plate 19 is fixedly mounted on the top of the housing 21 and is connected and fixed to the end plate 18 at one end of the claw arm. The telescopic cylinder 20 is installed inside the housing 21, with its telescopic end 27 extending downwards and a movable block 26 at its lower end. The claw teeth 22 are rotatably connected to the lower end of the housing 21 and are hinged to the movable block 26 via a hinge plate 25. The claw teeth 22 are provided with a fitting part 23, which is adapted to the steel pipe rod. When the telescopic cylinder 20 extends, it drives the movable block 26 to move downwards, thereby pushing the claw teeth 22 to open via the hinge plate 25. When the telescopic cylinder 20 retracts, it drives the movable block 26 to move upwards, causing the claw teeth 22 to engage via the hinge plate 25. Figure 5 The diagram shown illustrates the opening and closing principle of the claw.

[0055] Furthermore, in another embodiment, to allow the claw to swing and adjust its position locally, such as... Figure 4 As shown, with Figure 3 Unlike the non-swinging structure, the claw 11 is swingably connected to the front end of the claw arm 10, and the clamped rod has a limited swinging space; the forward and backward space and the swinging space are used to complete the local position adjustment of the rod.

[0056] Figure 4In the claw arm 10, there is a gap 28 between the end plate 18 and the top plate. The size of the gap 28 is set according to the size of the swing space. The end plate 18 is welded with a plate 30, and the top plate is welded with a plate 32. The plate and plate are rotatably connected together by a pivot 31, allowing the claw 11 to swing within a limited space. When the swing reaches the point where the top plate contacts the end plate, it is restricted. Preferably, springs 29 are also provided on both sides of the pivot 31. The springs 29 are supported between the top plate and the end plate, making the up-and-down swing of the claw elastic and damped.

[0057] Furthermore, in another implementation, such as Figure 2 As shown, the claw seat 70 has a sliding groove 15, and the slide seat 9 is provided with a slider, which includes a first slider 14 and a second slider 17. The slider engages with the sliding groove 15, and the driver 13 drives the first slider 14 to move along the sliding groove 15, thereby driving the slide seat 9 to move. In the illustration, the slide seat 9 slides in contact with a channel 12 located at the bottom of the claw seat 70, and the slider passes upward through the sliding groove 15. When the driver 13 extends or retracts, it drives the slider to move. Preferably, an elastic member 8 is also supported between the second slider 17 and the claw seat 70. Preferably, the driver 13 is an electric telescopic cylinder or a hydraulic cylinder.

[0058] Furthermore, in another embodiment, the claw can also be a conventional single-degree-of-freedom mechanical claw.

[0059] Furthermore, in another implementation, such as Figure 1 As shown, a pump body is provided at the front end of the auxiliary arm as a rotation drive component 6. The pump body is connected to the claw seat 70 and is used to drive the claw seat to rotate, thereby changing the state of the clamped rod. Preferably, the pump body can drive the claw seat to rotate 360°.

[0060] The present invention provides a construction method for the aforementioned scaffolding erection device, comprising:

[0061] like Figure 1 As shown, the base 1 moves flexibly to the position below the scaffolding erection site, and drives the mechanical claw 7 to pick up the poles from the material pile. According to the erection needs, the rotation drive component 6 is controlled to rotate, and the mechanical claw 7 is operated to adjust the poles to the state of horizontal, vertical, longitudinal or diagonal poles. The main arm and auxiliary arm are also controlled to supply the poles to the erection site. The worker makes local adjustments to align the poles with the fasteners, and then the driver 13 is started to perform the pole fitting action, pushing the steel pipe straight into the fastener. The worker uses tools to tighten the fastener bolts.

[0062] Furthermore, in another embodiment, by controlling the extension and retraction of the main boom to adjust the height, the swing of the auxiliary boom to adjust the angle, and the rotation of the mechanical claw to adjust the state, the rod and the fastener are initially aligned. Then, the worker controls the rod to move within the extension space to align with the fastener, or the worker controls the rod to move within the swing space to align with the fastener, or the worker controls the rod to move within both the extension and swing spaces to align with the fastener, and then the coupling action is performed.

[0063] Preferably, the worker controls the movement of the rod within the telescopic and swinging spaces, which together form a multi-dimensional adjustment space, allowing the worker to quickly adjust the rod to accurately align with the fastener.

[0064] Furthermore, in another implementation, visible light is used to assist in the positioning of the rods. Commonly used methods include infrared and green light. Taking infrared as an example, several infrared emitters (two are sufficient) emit infrared light to aim at the installation position of the rod. The infrared emitters can be installed in the robotic gripper or other locations. Then, guided by the infrared light, the main arm, auxiliary arm, and robotic gripper are controlled and adjusted to supply the rod to the installation position. Infrared light makes it easier to align the rod with the installation position, improving installation speed and accuracy. Taking the erection and installation of a crossbar as an example, the installation position is aimed at with infrared light, the auxiliary arm is adjusted to be level with the installation position, and then the rod is pushed horizontally to supply it to the installation position. Local alignment is then achieved through extension and retraction mechanisms, making it very convenient and quick, effectively accelerating the feeding speed and improving efficiency. Other diagonal rods, vertical rods, and longitudinal rods can also be accurately and quickly fed after infrared aiming.

[0065] Furthermore, in another embodiment, a remote control is also provided. The control module and corresponding buttons for controlling the movement of the base 1, adjusting the rotation and extension of the main arm 4, adjusting the swing of the auxiliary arm 5, adjusting the rotation of the rotation drive component 6, the action of the driver 13, and the extension and retraction of the telescopic cylinder 20 are all set on the remote control. The remote control is connected to the controlled component through a wireless communication module. The remote control is carried by the worker and operated on-site.

[0066] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. It can be applied to various fields suitable for the present invention. Further modifications can be readily implemented by those skilled in the art.
