DETAILED DESCRIPTION

[0031] The following is a specific embodiment of the present application and further describes the technical solutions of the present application in conjunction with the drawings, but the present application is not limited to these embodiments. In the following description, specific details such as specific configurations and components are provided only to help a comprehensive understanding of 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 of protection of the present application. In addition, descriptions of known functions and structures are omitted for the sake of clarity and brevity.

[0032] It should be noted that the embodiments and features in the present application can be combined with each other without conflict.

[0033] In order to perform various types of work, the connecting structure of the implement on the work arm can be designed as a detachable structure, and different implements can be connected on the work arm by means of the detachable connecting structure. The present application provides an implement double-lock quick-change connector installed at the end of the engineering machinery arm, used for connecting the implement, and the implement double-lock quick-change connector and the implement can be disassembled. By means of the implement double-lock quick-change connector provided by the present application, the implement on the engineering machinery arm can be safely disassembled, and the safety hazards of the current engineering machinery arm when disassembling the implement can be avoided.

[0034] Reference Figures 1-8 The present application provides an implement double-lock quick-change connector 100, which comprises a first connecting frame 10, a second connecting frame 20, a driving element 30, a first lock block 40, and a second lock block 50. The first connecting frame 10 is provided with a first connecting hook 11, and the first connecting hook 11 is provided with a first hook groove 111. The second connecting frame 20 is provided with a second connecting hook 21, and the second connecting hook 21 is provided with a second hook groove 211; when installed, the first connecting hook 11 and the second connecting hook 21 are used to reversely hook the first connecting part 301 and the second connecting part 302 on the implement 300. The driving element 30 is installed between the first connecting frame 10 and the second connecting frame 20 to drive the second connecting frame 20 to rotate relative to the first connecting frame 10 to reversely hook the first connecting hook 11 and the second connecting hook 21 on the implement 300 or release the implement 300.

[0035] The first lock block 40 is driven by the driving element 30 and can move to the outlet of the first hook groove 111 to form an obstruction to the first connecting part 301 on the implement 300 located in the first hook groove 111, or move away from the outlet of the first hook groove 111.

[0036] The second locking block 50 is movably connected to the second connecting frame 20. With the change of the angle state of the second connecting frame 20, the second locking block 50 moves relative to the second connecting frame 20 to the outlet of the second hook slot 211 to block the second connecting part 302 on the tool 300 in the second hook slot 211, or moves away from the outlet of the second hook slot 211.

[0037] In Figure 1 In the structure shown, the tool double-lock quick-change connector 100 is installed at the end of the arm frame 200, and the tool 300 is installed on the tool double-lock quick-change connector 100. The first connecting frame 10 is provided with a first connecting hook 11, and the first connecting hook 11 is provided with a first hook slot 111. When the tool is installed, the first connecting part 301 of the tool enters the first hook slot 111 and is hooked by the first connecting hook 11, and the second connecting part 302 of the tool enters the second hook slot 211 and is hooked by the second connecting hook 21. Further, the opening direction of the first hook slot 111 on the first connecting hook 11 and the opening direction of the second hook slot 211 on the second connecting hook 21 are opposite, so that the first connecting part 301 and the second connecting part 302 of the tool 300 can be reversely hooked. It should be understood that the opposite opening directions of the first hook slot 111 and the second hook slot 211 include two structural arrangements, opposite arrangement or opposite arrangement, and the opening direction of the first hook slot 111 and the opening direction of the second hook slot 211 are opposite. Figures 1-6 In the structure shown, the opening direction of the first hook slot 111 and the opening direction of the second hook slot 211 are opposite.

[0038] In an embodiment of the present application, the second connecting frame 20 is hinged to the first connecting frame 10, so that the second connecting frame 20 can rotate relative to the first connecting frame 10.

[0039] Further, the driving element 30 is installed between the first connecting frame 10 and the second connecting frame 20 to drive the second connecting frame 20 to rotate relative to the first connecting frame 10 to reversely hook or release the tool 300. The driving element 30 can be a pneumatic cylinder or an oil cylinder, one end of which is connected to the first connecting frame 10, and the other end is connected to the second connecting frame 20. When the driving element 30 is extended, the first connecting frame 10 and the second connecting frame 20 can rotate relative to each other to reversely move the first connecting hook 11 and the second connecting hook 21 to each other to approach or move away from each other. Referring to Figures 3-6 When the driving element 30 is extended, the first connecting hook 11 and the second connecting hook 21 move away from each other to hook the first connecting part 301 and the second connecting part 302 on the tool 300 to the two sides respectively. When the driving element 30 is retracted, the first connecting hook 11 and the second connecting hook 21 move close to each other, and the first connecting part 301 and the second connecting part 302 on the tool 300 are respectively separated from the first hook slot 111 and the second hook slot 211.

[0040] Further, the second locking block 50 is movably connected to the second connecting frame 20; as the angle state of the second connecting frame 20 changes, the second locking block 50 moves to the outlet of the second hook slot 211 to block the second connecting part 302 on the tool 300 located in the second hook slot 211, or moves away from the outlet of the second hook slot 211.

[0041] The tool double-lock quick-change connector 100 is located at the end of the arm frame 200, and the operator can change the angle state of the second connecting frame 20 and the second locking block 50 by operating the arm frame 200. In addition, since the second locking block 50 is movably connected to the second connecting frame 20, the operator can change the angle of the second locking block 50 by operating the arm frame 200, so that the second locking block 50 rotates relative to the second connecting frame 20 under the action of its own gravity. When installing the tool, the operator can change the angle of the second locking block 50 by operating the arm frame 200, so that the second locking block 50 moves to the outlet of the second hook slot 211 under the action of its own gravity to block the second connecting part 302 on the tool 300 located in the second hook slot 211, thereby preventing the second connecting part 302 from being separated from the second hook slot 211, and ensuring the reliability and stability of the tool installation. When disassembling the tool, the operator can change the angle of the second locking block 50 by operating the arm frame 200, so that the second locking block 50 moves away from the outlet of the second hook slot 211 under the action of its own gravity.

[0042] In an embodiment of the present application, the second locking block 50 is hinged to the second connecting frame 20; when the second locking block 50 moves to the outlet of the second hook slot 211, the structure part on the driving element 30 or the second connecting frame 20 limits the second locking block 50 to prevent it from moving away from the second hook slot 211. Further reference Figures 3-6 When the second locking block 50 moves to the outlet of the second hook slot 211, the connecting part of the driving element 30 and the second connecting frame 20 limits the second locking block 50.

[0043] Specific reference Figure 3 When installing the tool, the operator can change the angle of the second locking block 50 by operating the arm frame 200, so that the second locking block 50 rotates clockwise relative to the second connecting frame 20 under the action of its own gravity until it abuts against the limiting structure part (the connecting part of the driving element 30 and the second connecting frame 20). When disassembling the tool, the operator can change the angle of the second locking block 50 by operating the arm frame 200, so that the second locking block 50 rotates counterclockwise relative to the second connecting frame 20 under the action of its own gravity and moves away from the limiting structure part (the connecting part of the driving element 30 and the second connecting frame 20), thereby moving away from the outlet of the second hook slot 211 and removing the blockage to facilitate disassembly.

[0044] Reference Figures 3-6In an embodiment of the present application, the driving element 30 is provided with a movable slot 31 at one end close to the first connecting frame 10; the first connecting frame 10 is provided with a connecting column 12, which is arranged in the movable slot 31 and can move in the extension direction of the movable slot 31. The driving element 30 is further provided with a driving part 32 at one end close to the first connecting frame 10, which is used to drive the first locking block 40 to move; with the extension and contraction of the driving element 30, the connecting column 12 moves in the extension direction of the movable slot 31, so that the driving part 32 drives the first locking block 40 to rotate at a set angle relative to the first connecting frame 10.

[0045] In an embodiment of the present application, the first locking block 40 is connected to the connecting column 12 and can rotate based on the connecting column 12. In an embodiment of the present application, the first locking block 40 is provided with a driving slot 41; the driving part 32 is arranged in the driving slot 41.

[0046] Specifically, one end of the driving element 30 close to the first connecting frame 10 is the first end, and one end close to the second connecting frame 20 is the second end; the first end is provided with the movable slot 31 and the driving part 32. When the driving element 30 is extended, the movable slot 31 moves as a whole in the direction away from the second connecting frame 20; when the driving element 30 is contracted, the movable slot 31 moves as a whole in the direction close to the second connecting frame 20. With the movement of the movable slot 31, the connecting column 12 moves in the extension direction of the movable slot 31. When the driving element 30 is extended or contracted, under the guidance of the movable slot 31, the driving part 32 on the first end of the driving element 30 moves along the designed trajectory of the movable slot 31, and then the driving part 32 drives the first locking block 40 to rotate at a designed angle relative to the first connecting frame 10, so as to realize that when the tool is installed, the first locking block 40 is rotated to the outlet of the first hook slot 111 to block the first connecting part 301 on the tool 300 located in the first hook slot 111, so as to guarantee the reliability and stability of the tool installation, and when the tool is disassembled, the first locking block 40 is moved away from the outlet of the first hook slot 111.

[0047] Based on the above structure setting in the embodiment of the present application, when the tool is installed, first of all, refer to Figure 7 , first adjust the oil cylinder (driving element) to the retracted state, and operate the arm frame 200 to make the first connecting hook 11 on the first connecting frame 10 hook the first connecting part 301 on the tool 300, then refer to Figure 8, the operating arm frame 200 is operated to extend the oil cylinder (driving element), the first locking block 40 is rotated to the outlet of the first hook slot 111 to lock the first connecting part 301 on the tool 300 in the first connecting hook 11, at the same time, the second connecting hook 21 on the second connecting frame 20 is hooked on the second connecting part 302 on the tool 300; finally, the operating arm frame 200 is operated to move the second locking block 50 under the action of gravity to the outlet of the second hook slot 211 to lock the second connecting part 302 on the tool 300 in the second connecting hook 21.

[0048] When the tool is disassembled, the oil cylinder (driving element) is adjusted to the retracted state, the first locking block 40 is moved away from the outlet of the first hook slot 111, and the second locking block 50 is moved away from the outlet of the second hook slot 211 under the action of gravity by operating the operating arm frame 200.
