[0021] Example 1

[0022] This embodiment provides a clamping attachment, including: a clamp 8, a clamping device 7, a flipping device 6, a rotating device 4, a lateral shifting device 3, a fixed frame 1, and a swing cylinder 9. The clamping device 7 is mounted on the clamp 8 and drives the clamp 8 to perform opening and closing movements. The clamp 8 is connected to the flipping device 6 and is rotatably mounted on the working arm 5. The flipping device 6 drives the clamp 8 to rotate around the axis mounted on the working arm 5. The working arm 5 is connected to the output shaft of the rotating device 4 and drives the working arm 5 to rotate 360°. The rotating device 4 is mounted on the hanging component 2, the hanging component 2 is mounted on the lateral shifting device 3, and the lateral shifting device 3 is mounted on the fixed frame 1. The hanging component 2 is driven to move in the horizontal direction by the lateral shifting device 3.

[0023] like Figure 1 , Figure 2As shown, the lateral shifting device 3 is mounted on the fixed frame 1, and the hanging component 2 is mounted on the lateral shifting device 3. The hanging component 2 is driven to move horizontally by the lateral shifting device 3. The rotating device 4 is mounted on the hanging component 2, and the output end of the rotating device 4 extends from one end face of the hanging component 2 and connects to the working arm 5, driving the working arm 5 to rotate around axis one, which is perpendicular to the plane of the fixed frame 1. Inside the working arm 5, the clamp 8 is driven to rotate around axis two by the flipping device 6, which is parallel to the plane of the fixed frame 1. The flipping device 6 drives the clamp 8 to rotate at an angle of 0-180 degrees, realizing the up-and-down flipping of the clamp.

[0024] A swing cylinder 9 is also provided at the rear end of the fixed frame 1. One end of the swing cylinder 9 is installed on the fixed frame 1, and the other end is installed on the mounting bracket 10 at the rear end of the fixed frame 1. The mounting bracket 10 is used to install the device on the vehicle body. The swing cylinder 9 drives the fixed frame 1 and the device on it to rotate around the axis.

[0025] The clamping attachment provided in this embodiment has axes one, two, and three perpendicular to each other. The clamp 8 rotates on the Z-axis via a swing cylinder 9, enabling it to swing left and right. The clamp 8 rotates upwards on the X-axis via a rotating device 4, and rotates on the Y-axis via a flipping device 6, enabling it to swing up and down. The clamping attachment in this embodiment also includes a lateral movement device 3, which enables the working arm 5 to move left and right. This improves the clamping attachment's mobility and spatial adaptability, enhancing its operational capacity and efficiency. The working arm 5 is mounted on the lateral movement device 3 on the fixed frame 1 via a hook-and-mount component 2, further increasing the stability of the working arm 5 during operation.

[0026] Example 2

[0027] This embodiment provides a clamping attachment based on Embodiment 1. The fixing frame 1 is a plate-shaped structure with a through hole 101 extending through both end faces in the middle of the fixing frame 1. The through hole 101 is arranged horizontally. The lateral movement device 3 includes a lateral movement hydraulic cylinder 301, a guide rod 302, and a slider 303. The lateral movement hydraulic cylinder 301 is horizontally arranged in the through hole 101. The cylinder end of the lateral movement hydraulic cylinder 301 is installed in the through hole 101, and the telescopic end is installed in the middle of the hook-and-loop component 2. A guide rod 302 is installed on the upper and lower end faces of the fixing frame 1, respectively. The two ends of the guide rod 302 are fixed to the protrusions on both sides of the end face of the fixing frame 1. There is a gap between the guide rod 302 and the end face of the fixing frame 1. Several sliders 303 are installed on the guide rod 302. The gap facilitates the installation of the sliders 303. Block 303 is connected to the hanging component 2. The slider 303 on the guide rod 302 on the upper and lower end faces of the fixing frame 1 is connected to the upper and lower ends of the hanging component 2 respectively. The middle part of the hanging component 2 is connected to the telescopic end of the side-shifting hydraulic cylinder 301, and the upper and lower ends are connected to the slider 303 to achieve stable installation of the hanging component 2. When the side-shifting hydraulic cylinder 301 drives the hanging component 2 to move in the horizontal direction, the slider 303 slides on the guide. The slider 303 and the guide rod 302 guide the movement of the hanging component 2 and improve the stability of the hanging component 2 when it moves.

[0028] like Figure 1 , Figure 2 , Figure 4 As shown, the clamp 8 includes a mounting arm 803, an upper clamp 801, and a lower clamp 802. The upper clamp 801 and the lower clamp 802 are hinged to the mounting arm 803. A clamping device 7 is mounted on the mounting arm 803 and connected to either the upper clamp 801 or the lower clamp 802, driving the upper clamp 801 and the lower clamp 802 to rotate around the hinge point, thereby realizing the opening and closing movement of the clamp 8. Two clamps 8 are provided, arranged in parallel, and connected together by a connecting shaft 601. The two clamps 8 are rotatably mounted on the working arm 5 via the connecting shaft 601, and the clamp 8 is driven to rotate around the mounting point of the connecting shaft 601 on the working arm 5 by the flipping device 6.

[0029] Each clamp 8 is equipped with a tensioning device 7, and each tensioning device 7 includes two tensioning hydraulic cylinders 701. The telescopic ends of the two tensioning hydraulic cylinders 701 are connected to the upper clamp 801 and the lower clamp 802 respectively. The cylinder ends of the two tensioning hydraulic cylinders 701 are hinged to the mounting arm 803. The two tensioning hydraulic cylinders 701 drive the upper clamp 801 and the lower clamp 802 to rotate around their hinge point, thereby realizing the opening and closing between the upper clamp 801 and the lower clamp 802. The four tensioning hydraulic cylinders 701 in the two tensioning devices 7 are controlled by a set of oil circuits to achieve synchronous control of the four tensioning hydraulic cylinders 701.

[0030] In this embodiment, a rotating device 4 is also installed on the mounting component 2. The rotating device 4 drives the working arm 5 to rotate as a whole. The rotating device 4 includes a rotating hydraulic cylinder, a chain 401, a rotating gear, a drive shaft, and a rotating disk 402. The telescopic end of the rotating hydraulic cylinder is connected to one end of the chain 401. The other end of the chain 401 is mounted on the rotating gear, and its middle part engages with the rotating gear. The rotating gear is connected to one end of the drive shaft, and the other end of the drive shaft passes through the mounting component 2 and connects to the rotating disk 402. A torque spring is installed on the end of the rotating shaft connected to the rotating gear. The torque spring acts on the mounting component 2, so that the torque spring has an initial torque to drive the rotating gear to rotate. The torque spring drives the drive shaft and the drive gear to rotate in one direction. Specifically, when the rotating hydraulic cylinder extends, the rotating gear is driven to rotate by the torque spring on the rotating shaft, and the middle part of the chain 401 engages with the rotating gear. After rotating 360°, the rotary hydraulic cylinder reaches its maximum extension stroke. When the rotary hydraulic cylinder retracts, it pulls the chain 401 towards the rotary hydraulic cylinder. The chain 401, which meshes with the rotary gear, gradually disengages from the rotary gear, causing the rotary gear to rotate. Simultaneously, the torque spring on the drive shaft is gradually compressed, preparing for the next extension of the rotary hydraulic cylinder. The drive shaft passes through the mounting component 2, and a bearing can be used to connect the drive shaft and the mounting component 2. The bearing supports the drive shaft and reduces friction between the drive shaft and the mounting component 2, ensuring stable rotation of the drive shaft. One end of the torque spring acts on the end face of the mounting component 2, and the other end acts on the rotary gear, driving the torque spring to rotate.

[0031] like Figure 1 , Figure 2 As shown, two clamps 8 are installed at the front end of the working arm 5. The two clamps 8 are arranged in parallel and are mounted on the working arm 5 by a flipping device 6. The flipping device 6 includes a connecting shaft 601 for rotatably mounting the two clamps 8 on the working arm 5. Both ends of the connecting shaft 601 pass through the mounting arms 803 on the two clamps 8 and are rotatably connected to the working arm 5. A drive shaft 602 is vertically mounted in the middle of the connecting shaft 601. The other end of the drive shaft 602 extends into the interior of the working arm 5 and is connected to a flipping hydraulic cylinder. The telescopic end of the flipping hydraulic cylinder is connected to the drive shaft 602. The cylinder end of the flipping hydraulic cylinder is installed inside the working arm 5. The flipping hydraulic cylinder drives one end of the drive shaft 602 to move up and down, and the drive shaft 602 drives the connecting shaft 601 to rotate, thereby realizing the up and down flipping of the clamps 8. The flipping device 6 drives the clamps 8 to flip up and down by 90°.

[0032] like Figure 2 , Figure 3 , Figure 4As shown, two feet 11 are provided at the bottom of both the working arm 5 and the hanging component 2. The feet 11 are used to support the working arm 5 and the hanging component 2. When the rotating device 4 adjusts the position of the clamp 8, the feet 11 on the hanging component 2 support the ground to improve the stability of the device. When the flipping device 6 adjusts the range and position of the clamp 8, the feet 11 on the working arm 5 and the feet 11 on the hanging component 2 both support the ground to improve the stability of the device.

[0033] like Figure 5 As shown, the rear end of the fixed frame 1 is hinged to the mounting frame 10. Two swing cylinders 9 are provided on the mounting frame 10. The two swing cylinders 9 are arranged on both sides of the mounting frame 10. The telescopic end of the swing cylinder 9 is hinged to the mounting frame 10, and the cylinder end is mounted on the fixed frame 1. The swing cylinder 9 drives the fixed frame 1 to swing left and right. The fixed frame 1 is used to mount the entire attachment on the vehicle body for use.

[0034] In use, the swing cylinder 9 enables the working arm 5 to swing left and right on the clamp 801, the lateral shifting device 3 enables the clamp 8 to move horizontally, the flipping device 6 enables the clamp 8 to swing up and down, and the rotating device 4 enables the clamp 8 to rotate as a whole. The clamping attachment provided in this embodiment, compared to existing attachments, adds a rotating device 4 and a lateral shifting device 3, making the clamp 8 more flexible and adaptable to more working environments. Furthermore, compared to existing attachments, this embodiment requires only minor modifications to the clamp 8 after adding the lateral shifting device 3 and the rotating device 4. The rotating device 4 is installed by adding a hooking component 2, and the working arm 5 is mounted on the lateral shifting device 3 via the hooking component 2. The lateral shifting and rotation are driven by two sets of cylinders, resulting in a simple structure. When dealing with goods placed at an angle to the ground, the rotating device 4 drives the clamp 8 to rotate, allowing the upper clamp 801 and lower clamp 802 of the clamp 8 to clamp the goods. When clamping the goods, the lateral shifting device 3 can be used to adjust the left and right position of the clamp 8 after approaching the goods before clamping them. A swinging device is added to the rear end of the lateral movement device 3 to enable the clamp 8 to swing left and right, thereby improving the flexibility of the clamp 8 and enabling precise control of the clamp 8.
