[0019] Embodiment 1 like Figures 1 to 5 As shown, the present invention provides a device and method for installing and constructing a special-shaped steel structure, including a mobile support frame 1. The mobile support frame 1 is moved by a structure in the prior art. The mobile support frame 1 serves as a supporting base for the entire device, provides an installation position for other components, and can be moved to different construction positions, so as to facilitate the grabbing and installation of the special-shaped steel structure. A first slider 12 is provided on the top of the mobile support frame 1. The first slider 12 is connected to a first moving component. The first slider 12 can move on the top of the mobile support frame 1 under the drive of the first moving component, so as to adjust the horizontal position of the entire grabbing and installation component. The first moving component includes a hydraulic cylinder 11, which is connected to the first slider 12. The hydraulic cylinder 11 can push the first slider 12 to move, thereby realizing the precise position adjustment of the device in the horizontal direction, ensuring that the special-shaped steel structure can be accurately grabbed and placed.

[0020] The bottom of the first slider 12 is connected to the first telescopic rod 2. The first telescopic rod 2 adjusts the height of the mechanical claw 8 in the vertical direction to adapt to the requirements of grabbing and installing special-shaped steel structures of different heights, thereby increasing the vertical operating range of the device and improving the adaptability to steel structures of different heights. The first telescopic rod 2 is connected to the first rotating assembly. The first rotating assembly can drive the first telescopic rod 2 to rotate, and the angle can be accurately adjusted during the installation process. The first rotating assembly includes a first rotating shell 3, a first motor 34, a first gear 31, a second gear 32 and a first rotating rod 33.

The outer side of the first rotating rod 33 is fixedly connected to the fixed sleeve rod 4 , and the rotation of the first rotating rod 33 can drive the fixed sleeve rod 4 to rotate.

[0021] The first rotating assembly is fixedly connected to the fixed sleeve rod 4, and a second moving assembly is arranged inside the fixed sleeve rod 4.

The second motor 41 can drive the bidirectional screw 47 to rotate through the meshing transmission of the first bevel gear 42 and the second bevel gear 43, thereby realizing that the first moving rod 44 and the second moving rod 45 move in opposite directions at the same time. Slide grooves 46 are arranged on both sides of the first moving rod 44 and the second moving rod 45, and a slider corresponding to the slide groove 46 is arranged inside the fixed sleeve rod 4, which can provide support and guidance for the second moving assembly, the first moving rod 44 and the second moving rod 45, thereby ensuring the stable operation of each component.

[0022] The first moving rod 44 and the second moving rod 45 are both provided with a second telescopic rod 5 on one side close to the moving support frame 1. The second telescopic rod 5 is connected to the second rotating assembly. The second telescopic rod 5 further adjusts the position of the mechanical claw 8 in the vertical direction, and cooperates with the first telescopic rod 2 to achieve more precise height adjustment, thereby improving the position adjustment accuracy of the mechanical claw 8 in the vertical direction, and ensuring that the special-shaped steel structure can be accurately grasped and placed. The second rotating assembly includes a second rotating shell 6, and a third motor 61 is provided inside the second rotating shell 6. The second rotating shell 6 provides support for the third motor 61. The third motor 61 is connected to the second rotating rod 7, and the second rotating rod 7 is connected to the mechanical claw 8. The third motor 61 can drive the second rotating rod 7 to rotate to enable the mechanical claw 8 to grasp the special-shaped steel structure. An ultrasonic sensor is provided at the bottom of the second rotating shell 6. The ultrasonic sensor can detect the distance and position information from the special-shaped steel structure, which helps to achieve accurate placement operation.

[0023] The second rotating assembly is connected to the mechanical claw 8, which includes a claw sleeve 81, a locking assembly 82 is arranged in the claw sleeve 81, and the first connecting rod 83 and the second connecting rod 84 are symmetrically arranged on both sides of the claw sleeve 81.

The rotation of the second rotating rod 7 can make the moving block 87 move along the second rotating rod 7, and the mechanical claw 8 is grasped by the cooperation of the first connecting rod 83, the second connecting rod 84 and the third connecting rod 86. A rubber pad is arranged on the inner side of the clamping claw 85, and the rubber pad can increase the friction and prevent the steel structure from slipping.

[0024] A locking assembly 82 is provided inside the mechanical claw 8, which improves the safety and reliability of the grasping and avoids safety accidents caused by the steel structure falling during the installation process. The locking assembly 82 includes a ratchet 821, which is fixedly connected to the claw sleeve 81, and a rotating block 822 is provided inside the ratchet 821. The rotating block 822 is fixedly connected to the second rotating rod 7, and the rotation of the second rotating rod 7 can drive the rotating block 822 to rotate. Two ratchets 823 are provided inside the rotating block 822, and the ratchets 823 are hinged to the rotating block 822. A spring 824 is provided between the ratchets 823 located outside the rotating block 822 and the rotating block 822, and the spring 824 and the ratchets 823 and the spring 824 and the rotating block 822 are fixedly connected. An armature 825 is fixedly connected to the ratchets 823 located inside the rotating block 822, and an electromagnet 826 corresponding to the armature 825 is provided on the rotating block 822. When the electromagnet 826 is powered off, the electromagnet 826 is disconnected from the armature 825, and the pawl 823 is unfolded under the action of the spring 824. After the mechanical claw 8 grabs the steel structure, it is locked to prevent accidental release; when the electromagnet 826 is powered on, the electromagnet 826 is adsorbed on the armature 825, the spring 824 is compressed, and the pawl 823 is disengaged from the ratchet 821 to achieve unlocking. At this time, the second rotating rod 7 can be rotated forward and reversely to achieve the grasping and releasing of the mechanical claw 8.

[0025] The first moving assembly, the first telescopic rod 2 and the second telescopic rod 5 are all hydraulic systems, which can generate large forces and torques, can easily drive heavy mechanical parts, and can accurately adjust the flow, pressure and flow direction of the hydraulic oil, thereby achieving precise control.
