[0033] Example 1

[0034] like Figure 1-7 As shown, this utility model provides a technical solution: including a connector 1, a first adjusting arm 4 and a second adjusting arm 4. A hydraulic quick-connect coupling 2 is welded to the top of the connector 1, and a locking pin 3 with a through structure is installed on the hydraulic quick-connect coupling 2. The first adjusting arm 4 with a rotating structure is embedded in the left side of the bottom end of the connector 1 through a rotating shaft. The second adjusting arm 5 with a rotating structure is embedded in the right side of the bottom end of the connector 1 through a rotating shaft. A hydraulic cylinder 6 with a rotating structure is installed in the inner end of the first adjusting arm 4. The piston rod 7 in the hydraulic cylinder 6 is rotatably connected to the second adjusting arm 5.

[0035] A rotating clamping arm A8 is installed inside the bottom end of the first adjusting arm 4, and a rotating clamping arm B9 is embedded inside the bottom end of the second adjusting arm 5. A rotating adjusting device 10 is installed between the first adjusting arm 4 and the clamping arm A8, and between the second adjusting arm 5 and the clamping arm B9. The adjusting device 10 includes a connecting cylinder 1003. A threaded first threaded post 1001 is embedded inside the upper end of the connecting cylinder 1003, and a threaded second threaded post 1004 is embedded inside the lower end of the connecting cylinder 1003.

[0036] Both gripping arms A8 and B9 are rotatably connected to the mounting frame 12 via connectors 11 at their bottom ends. The mounting frame 12 has sliding connecting brackets 13 embedded at both its upper and lower ends. A gripping plate 14 is welded to the inner end of the connecting bracket 13. A pressure sensor 17 is fixed to the middle of the inner end of the gripping plate 14. A rubber protective layer 16 is provided on the inner end face of the gripping plate 14.

[0037] Connector 1 is detachably connected to the forklift attachment frame via hydraulic quick-connect coupling 2, achieving efficient quick disassembly and installation.

[0038] The first adjusting arm 4 and the second adjusting arm 5 have the same structure and are both bent structures, which realizes the included angle, making it easier for the clamping plate to clamp the ton container.

[0039] Nuts 1002 are installed on both the first threaded post 1001 and the second threaded post 1004 to fix the two threaded posts and increase their stability.

[0040] The threads on the first threaded post 1001 and the second threaded post 1004 have opposite structures. The expansion and contraction of the two threaded posts are achieved by rotating the connecting cylinder.

[0041] The clamping plates 14 at the upper and lower ends of the inner side of the mounting frame 12 are aligned to ensure the stability and firmness of the clamping cylinder.

[0042] The clamping plate 14 has an arc-shaped structure, designed to correspond to the shape of the ton container, making the clamping more secure.

[0043] The pressure sensor 17 is located inside the protective layer 16. During the clamping process of the clamping plate clamping the ton container, the pressure sensor can receive the pressure in real time. The pressure sensor model is MPX5010DP.

[0044] There is a gap between the hydraulic cylinder 6 and the top of the ton container being gripped, to prevent the ton container from colliding with the hydraulic cylinder during the process of the hydraulic cylinder controlling the gripping arm to grip the ton container.

[0045] Working principle:

[0046] In use, the entire clamping device is detachably connected to the forklift attachment frame via the hydraulic quick-change connector 2 at the top of the connector 1, so as to realize the docking of the device with the power equipment. The locking pin 3 with a through structure is inserted into the hydraulic quick-change connector 2 to lock the connection part, ensuring that the device is firmly connected to the forklift attachment frame during operation and preventing it from falling off.

[0047] The clamping angle is further adjusted by adjusting device 10. When the connecting cylinder 1003 is rotated, the first threaded post 1001 and the second threaded post 1004 will extend and retract simultaneously, thereby adjusting the angle between the first adjusting arm 4 and the clamping arm A8, and between the second adjusting arm 5 and the clamping arm B9. After the adjustment is completed, the adjusting device 10 is locked by tightening the nuts 1002 on the first threaded post 1001 and the second threaded post 1004 to fix the clamping angle.

[0048] Move the forklift to bring the entire device close to the target ton container. Adjust the position of the forklift so that the mounting frame 12 at the bottom of the clamping arm A8 and clamping arm B9 is aligned with the two sides of the ton container. Ensure that the clamping plates 14 at the upper and lower ends inside the mounting frame 12 are aligned and can accurately fit the sides of the ton container.

[0049] The hydraulic cylinder 6 drives the piston rod 7 to retract, and the first adjusting arm 4 and the second adjusting arm 5 continue to rotate inward, driving the clamping arm A8 and the clamping arm B9 to move inward synchronously. The bottom ends of the clamping arm A8 and the clamping arm B9 drive the mounting frame 12 to move through the connecting piece 11. The height of the Gnu ton is used to slide the connecting frame 13 in the mounting frame 12 up and down, adjusting the distance between the two clamping plates 14 so that the clamping plates 14 gradually approach the side of the ton.

[0050] The rubber protective layer 16 on the inner end face of the clamping plate 14 first contacts the ton container to prevent the clamping plate from directly rubbing and damaging the surface of the ton container. As the clamping force increases, the pressure sensor 17 inside the protective layer 16 detects the clamping pressure and provides real-time feedback of pressure data to ensure that the clamping force is moderate, so as to ensure that the ton container does not loosen and to avoid excessive pressure that could damage the ton container.

[0051] After the pressure sensor 17 reports stable pressure, operate the forklift to lift or move the ton container. At this time, a gap is maintained between the hydraulic cylinder 6 and the top of the ton container being gripped to prevent interference between the hydraulic cylinder and the ton container during handling.

[0052] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
