DETAILED DESCRIPTION

[0020] The preferred embodiments of the utility model are described below in combination with the drawings, and it should be understood that the preferred embodiments described herein are only used for illustrating and explaining the utility model, and are not used for limiting the utility model.

[0021] Embodiments, refer to the drawings Figure 1 The utility model provides a kind of water conservancy pile clamping device for excavator, including boom 100, boom 100 one end is used to connect with excavator, boom 100 is rotated by excavator drive, the other end rotationally arranged stick 200, stick 200 is rotationally arranged bucket 400 in the end away from boom 100, boom 100 is provided with the first drive cylinder 300 for driving stick 200 rotation, stick 200 is provided with the second drive cylinder 500 for driving bucket 400 rotation, pile clamping unit 600 is also installed on stick 200 near the end of bucket 400, as shown in the figure Figure 3As shown, the pile clamping unit 600 includes a clamping support 610, which is fixedly provided with a rotating mounting frame 620 and a frame mounting frame 630. The clamping support 610 is mounted on the arm 200 through the rotating mounting frame 620 and the frame mounting frame 630. In the specific assembly structure, the rotating mounting frame 620 is rotatably connected with the arm 200. The frame mounting frame 630 is detachably provided with a first limiting rod 631 and a second limiting rod 632. In specific applications, the first limiting rod 631 and the second limiting rod 632 can adopt the form of a bolt fastening mechanism. The first limiting rod 631 and the second limiting rod 632 are arranged at intervals. The first limiting rod 631 is externally sleeved with a first clamping pad 633. The second limiting rod 632 is externally sleeved with a second clamping pad 634. The first clamping pad 633 and the second clamping pad 634 are used for filling. The first limiting rod 631, the second limiting rod 632, and the left and right side walls of the frame mounting frame 630 form a frame structure. During installation, the rotating mounting frame 620 is first rotatably mounted on the arm 200 through a rotating shaft. Then, the second limiting rod 632 sleeved with the second clamping pad 634 is installed. Then, the arm 200 is made to enter the frame structure formed by the first limiting rod 631, the second limiting rod 632, and the left and right side walls of the frame mounting frame 630 from the gap of the installation position of the first limiting rod 631 through the rotation of the clamping support 610. Then, the first limiting rod 631 sleeved with the first clamping pad 633 is installed on the frame mounting frame 630. In this way, the clamping support 610 is fixed to the arm 200 through the cooperation of the rotating mounting frame 620 and the frame mounting frame 630. The first clamping pad 633 and the second clamping pad 634 serve to fill the gap between the first limiting rod 631, the second limiting rod 632, and the arm 200. By changing the thickness of the first clamping pad 633 and the second clamping pad 634, the installation of the pile clamping unit 600 can be made more stable. The clamping support 610 is provided with a pile chuck. The pile chuck includes a fixed clamping plate 640 and a movable clamping plate 650 arranged at intervals. The fixed clamping plate 640 is fixedly connected with the clamping support 610. The fixed clamping plate 640 and the movable clamping plate 650 are elastically connected through a plurality of clamping plate reset elastic members 660. In this embodiment, the clamping plate reset elastic members 660 adopt the form of springs. A clamping plate limiting guide rod 670 is arranged in each clamping plate reset elastic member 660. One end of the clamping plate limiting guide rod 670 is fixedly connected with the movable clamping plate 650, and the other end is slidably sleeved with the fixed clamping plate 640. In this way, the fixed clamping plate 640 and the movable clamping plate 650 can always be kept in a parallel state during the approach of the movable clamping plate 650 to the fixed clamping plate 640, which is conducive to the clamping of the water conservancy pile 700. Similarly, in order to more stably clamp the water conservancy pile 700 and adapt to water conservancy piles 700 of different sizes, an arc-shaped clamping groove is arranged on the end face of the side of the fixed clamping plate 640 facing the movable clamping plate 650. An arc-shaped clamping groove is also arranged on the end face of the side of the movable clamping plate 650 facing the fixed clamping plate 640.The arc-shaped clamping groove allows for a closer fit to the outer wall of the 700mm hydraulic pile.

[0022] In a more optimized solution, the clamping plate limiting guide rod 670 is threadedly connected to a limiting adjustment nut 680. The limiting adjustment nut 680 is located on the side of the fixed clamping plate 640 facing away from the movable clamping plate 650. By rotating the limiting adjustment nut 680, the initial distance between the fixed clamping plate 640 and the movable clamping plate 650 can be adjusted, making the application range of the pile clamp more flexible.

[0023] The working principle of this embodiment is as follows:

[0024] First, with the cooperation of the boom 100 and the stick 200, the hydraulic pile body 700 is inserted between the fixed clamping plate 640 and the movable clamping plate 650. Then, the bucket 400 is rotated, and the movable clamping plate 650 is pushed closer to the fixed clamping plate 640 through the inner wall of the bucket 400, as shown in the attached figure. Figure 2 As shown, the hydraulic pile 700 is held securely by the movable clamping plate 650 and the fixed clamping plate 640. At this point, by adjusting the boom 100 and the stick 200, the hydraulic pile 700 is moved to the pile lowering position and adjusted to the vertical direction. Then, the hydraulic pile 700 is controlled to insert downwards into the bottom of the water. After the pile driving is completed, the bucket 400 is controlled to rotate in the opposite direction. At this time, the movable clamping plate 650 moves away from the fixed clamping plate 640 under the action of the clamping plate reset elastic element 660. In this way, the movable clamping plate 650 and the fixed clamping plate 640 release their clamping of the hydraulic pile 700. This device is simple to install, has a wide range of applications, and can be installed on excavators of various specifications and models for temporary emergency rescue. It can also be removed without affecting the original function of the excavator when it is no longer needed.
