DETAILED DESCRIPTION

[0032] The following are specific embodiments of the present application and in conjunction with the accompanying drawings, the technical scheme of the present application is further described, but the application is not limited to these embodiments. In the following description, specific details such as specific configurations and components are provided only to help fully understand the embodiments of the present application. Therefore, it should be clear to those skilled in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. In addition, for clarity and brevity, the description of known functions and structures has been omitted.

[0033] It should be noted that, unless there is any conflict, the embodiments and features in the embodiments of this application can be combined with each other.

[0034] The present invention provides a sling installation gripper that can be used on a robotic arm to automatically grasp slings. Specifically, it is used to install overhead catenary slings in tunnels, thereby improving the automation level of tunnel sling installation, reducing human involvement, and increasing installation efficiency. A detailed description is provided below with reference to the accompanying drawings.

[0035] refer to Figure 1The clamp 100 for mounting a sling includes a clamp bracket 10, a first clamp arm 20, a second clamp arm 30, and a drive element 50. The first clamp arm 20 is mounted on the clamp bracket 10 and is rotatable relative to the clamp bracket 10. The first clamp arm 20 is provided with a first clamping block 21, which is rotatably mounted on the first clamp arm 20. The second clamp arm 30 is mounted on the clamp bracket 10 and is rotatable relative to the clamp bracket 10. The second clamp arm 30 is provided with a second clamping block 31, which is rotatably mounted on the second clamp arm 30. The second clamping block 31 is arranged opposite to the first clamping block 21. The drive element 50 is used to drive the first clamp arm 20 and the second clamp arm 30 to rotate relative to the clamp bracket 10, so that the first clamping block 21 and the second clamping block 31 move closer to or farther away from each other to clamp or release the sling. When the column-mounting clamp 100 clamps a column, the first clamping block 21 and the second clamping block 31 adaptively adjust to mate with the side surfaces of the column 60, thereby achieving automated, stable, and reliable clamping of the column. Furthermore, the first clamping block 21 is hinged to the first clamping arm 20, allowing for free rotation and adjustment around the hinge. The second clamping block 31 is hinged to the second clamping arm 30, allowing for free rotation and adjustment around the hinge.

[0036] The sling mounting clamp 100 can be mounted at the end of a robotic arm and is used to clamp or release the sling 60. To clamp, the drive element 50 drives the first and second clamp arms 20, 30 on the clamp bracket 10 to rotate in opposite directions, causing the first and second clamp blocks 21, 31 to move toward each other to clamp the sling 60 positioned therebetween. To release, the drive element 50 drives the first and second clamp arms 20, 30 on the clamp bracket 10 to rotate in opposite directions, causing the first and second clamp blocks 21, 31 to move away from each other to release the sling 60 positioned therebetween. Furthermore, the first clamping block 21 is rotatably mounted on the first clamping arm 20, and the second clamping block 31 is rotatably mounted on the second clamping arm 30. During the clamping process, as the first clamping block 21 contacts the side surface of the sling 60, the first clamping block 21 can be adaptively rotated and adjusted to fit the side surface of the sling 60; and as the second clamping block 31 contacts the side surface of the sling 60, the second clamping block 31 can be adaptively rotated and adjusted to fit the side surface of the sling 60. Therefore, during the clamping process, the first clamping block 21 and the second clamping block 31 respectively fit the side surfaces of the sling 60 from both sides, thereby achieving stable and reliable clamping of the sling 60.

[0037] Furthermore, the clamping surfaces of the first clamping block 21 and the second clamping block 31 are adapted to the side surfaces of the suspender and can fit together when clamped. Figure 8The sling 60 is a square structure with a flat side surface. In one embodiment of the present application, the first clamping block 21 and the second clamping block 31 are nylon blocks with a flat clamping surface for contacting with the side surface of the sling during clamping.

[0038] refer to Figure 2 and Figure 4 In one embodiment of the present application, the first gripper arm 20 includes a first sleeve 22, a first front arm 23, and a first rear arm 24. The first sleeve 22 and the gripper bracket 10 are rotatably connected via a hinge. The first front arm 23 is fixed to the first sleeve 22. The first clamping block 21 is mounted on the first front arm 23. The first rear arm 24 is fixed to the first sleeve 22. In this structure, the first front arm 23 and the first rear arm 24 are respectively fixed to the first sleeve 22 and are hingedly connected to the gripper bracket 10 by the first sleeve 22. The three components form a single unitary structure and can be rotated and adjusted as a whole around the hinge position.

[0039] refer to Figure 3 and Figure 5 In one embodiment of the present application, the second gripper arm 30 includes a second sleeve 32, a second front arm 33, and a second rear arm 34. The second sleeve 32 and the gripper bracket 10 are rotatably connected via a hinge. The second front arm 33 is fixed to the second sleeve 32. The second clamping block 31 is mounted on the second front arm 33. The second rear arm 34 is fixed to the second sleeve 32. In this structure, the second front arm 33 and the second rear arm 34 are respectively fixed to the second sleeve 32 and are hingedly connected to the gripper bracket 10 by the second sleeve 32. The three components form a single unitary structure and can be rotated and adjusted as a whole around the hinge position.

[0040] Further references Figure 6 The first front arm 23 and the second front arm 33 are arranged opposite to each other, and the first rear arm 24 and the second rear arm 34 are arranged opposite to each other; the driving element 50 is a telescopic driving element, which is connected between the first rear arm 24 and the second rear arm 34 to drive the first rear arm 24 and the second rear arm 34 to rotate in opposite directions. Specifically, the telescopic driving element can be a pneumatic cylinder or an oil cylinder. Figure 6In the illustrated structure, when the telescopic drive element extends, the first rear arm 24 and the second rear arm 34 move away from each other, while the first front arm 23 and the second front arm 33 move toward each other. At this point, the first clamping block 21 on the first front arm 23 and the second clamping block 31 on the second front arm 33 move toward each other, clamping the suspension post 60 located therebetween. Conversely, when the telescopic drive element contracts, the first rear arm 24 and the second rear arm 34 move toward each other, while the first front arm 23 and the second front arm 33 move away from each other. At this point, the first clamping block 21 on the first front arm 23 and the second clamping block 31 on the second front arm 33 move away from each other, releasing the clamped suspension post 60.

The connecting arm 40 is hingedly connected to the first rear arm 24 and the second rear arm 34, respectively. In this structure, the first rear arm 24 and the second rear arm 34 are connected by the connecting arm 40, which ensures that the first clamping arm 20 and the second clamping arm 30 can move in opposite directions, reducing the degree of freedom of the mechanism.

[0042] refer to Figure 6 In one embodiment of the present application, the connecting arm 40, the first rear arm portion 24, and the driving element 50 are hinged at the same point to form a composite hinge.

[0043] refer to Figure 6 In one embodiment of the present application, the second rear arm 34 includes a first sub-arm 341 and a second sub-arm 342; the first sub-arm 341 is located on the side of the second sleeve 32 away from the second front arm 33, and the second sub-arm 342 is located on the side of the second sleeve 32 close to the second front arm 33; the first rear arm 24 and the first sub-arm 341 are positioned opposite to each other, and the driving element 50 is connected between the first rear arm 24 and the first sub-arm 341; the second sub-arm 342 is hinged to the connecting arm 40.

[0044] exist Figure 6In the illustrated structure, as the telescopic drive element extends, the first rear arm 24 and the first sub-arm 341 move away from each other, while the first forearm 23 and the second forearm 33 move toward each other. At this point, the first clamping block 21 on the first forearm 23 and the second clamping block 31 on the second forearm 33 move toward each other, clamping the suspension post 60 located therebetween. Conversely, when the telescopic drive element contracts, the first rear arm 24 and the first sub-arm 341 move toward each other, while the first forearm 23 and the second forearm 33 move away from each other. At this point, the first clamping block 21 on the first forearm 23 and the second clamping block 31 on the second forearm 33 move away from each other, releasing the clamped suspension post 60. Furthermore, the connecting arm 40, connected between the second sub-arm 342 and the first rear arm 24, allows the first and second rear arms 24, 34 to move in conjunction with each other, eliminating redundant degrees of freedom.

[0045] refer to Figure 7 In one embodiment of the present application, the clamp bracket 10 includes a first plate-shaped body 11, a second plate-shaped body 12, and a column 13, wherein the first plate-shaped body 11 and the second plate-shaped body 12 are arranged opposite to each other; the column 13 connects the first plate-shaped body 11 and the second plate-shaped body 12; the first sleeve and the second sleeve 32 are both located between the first plate-shaped body 11 and the second plate-shaped body 12.
