[0021] This application provides a rocker arm device for a shipboard sludge pumping equipment, which solves the problem that as the pumping height increases, the stability of the rocker arm device deteriorates, resulting in large swaying during pumping and a risk of tipping over, posing a significant safety hazard. The device achieves this by using a hydraulic rod 21 to drive the connecting seat 22 to slide on the support column 11, thereby causing the connecting rods 24 on both sides to extend outwards, which in turn causes the fixed plate 26 to move outwards. The fixed plate 26 remains connected to the hull, thus reinforcing the entire rocker arm. This allows for adjustments to the extension angle of the connecting rods 24 according to the pumping height, ensuring the rocker arm remains in its most stable state.

[0022] This utility model discloses a rocker arm device for a shipboard mud pumping equipment.

[0023] According to the appendix Figure 1-3 As shown, the device includes a rocker arm unit 1, on which a reinforcing unit 2 is provided. The rocker arm unit 1 includes a support column 11, a rotating arm 13 and a folding arm 14. The support column 11 is fixedly installed on the hull, the rotating arm 13 is located above the support column 11, and one end of the folding arm 14 is rotatably connected to the front end of the rotating arm 13.

[0024] Specifically disclosed, the reinforcement unit 2 includes a connecting seat 22, a connecting rod 24, and a fixing plate 26. The connecting seat 22 is slidably connected to the support column 11. The connecting rod 24 is located on both sides of the connecting seat 22. The fixing plate 26 is movably connected to the bottom end of the connecting rod 24. As the connecting rod 24 unfolds outward, it can drive the fixing plate 26 to move outward. The fixing plate 26 is always connected to the hull, thereby reinforcing the entire rocker arm unit 1. It can adjust the unfolding angle of the connecting rods 24 on both sides according to the adjustment of the pumping height, ensuring that the rocker arm unit 1 is always in the most stable state.

[0025] Furthermore, the rocker arm unit 1 also includes a rotating disk 12, which is fixedly connected to the top of the support column 11. One end of the rotating arm 13 is rotatably connected to the rotating disk 12. By setting the rotating disk 12, the rocker arm can rotate 360 ​​degrees.

[0026] Furthermore, the rocker arm unit 1 also includes a pump pipe 15, which is installed on the support column 11, the rotating arm 13 and the folding arm 14, and can deliver cement to the required location through the pump pipe 15.

[0027] Furthermore, the reinforcement unit 2 also includes a hydraulic rod 21, the side of which is fixedly connected to the support column 11, and the output end of the hydraulic rod 21 is fixedly connected to the connecting seat 22. The hydraulic rod 21 drives the connecting seat 22 to slide on the support column 11, thereby driving the connecting rods 24 on both sides to unfold outward.

[0028] Furthermore, the reinforcement unit 2 also includes a first hinge seat 23, which is fixedly connected to both sides of the connecting seat 22. One end of the connecting rod 24 is rotatably connected to the first hinge seat 23. By setting the first hinge seat 23, the connecting rod 24 can unfold outward during the downward sliding process of the connecting seat 22.

[0029] Furthermore, the reinforcement unit 2 also includes a second hinge seat 25, which is fixedly connected to the bottom end of the connecting rod 24. By setting the second hinge seat 25, the fixing plate 26 can always be connected to the hull.

[0030] Furthermore, the top of the fixed plate 26 is rotatably connected to the second hinge seat 25. During the unfolding process of the connecting rod 24, the top of the fixed plate 26 rotates on the second hinge seat 25 to ensure that the fixed plate 26 can always be connected and fit with the hull, thus ensuring the stability of the rocker arm.

[0031] Working principle: First, adjust the rotating arm 13 and folding arm 14 to the required pumping height and adjust them to the appropriate position. Then, adjust the reinforcement unit 2 according to the height of the entire rocker arm unit 1. Drive the hydraulic rod 21 to move the connecting seat 22, which in turn drives the connecting rods 24 on both sides to unfold outward. The fixed plate 26 is always connected to the hull, which in turn drives the fixed plate 26 to move outward on the hull until the angle of the connecting rod 24 is adjusted to the appropriate position, thus completing the reinforcement of the rocker arm unit 1.
