Description

Technical Field

[0001] This utility model relates to the field of excavator rocker arm support technology, and in particular to an excavator rocker arm support device. Background Technology

[0002] In the manufacturing and maintenance of excavators, installing the control lever is a typical task that requires both physical strength and skill. Because the lever itself is quite heavy, and its installation location is usually deep inside the cab or in a space where direct force cannot be applied, operators often need to hold it by hand for extended periods while simultaneously aligning and tightening it. This process not only easily leads to muscle fatigue and increases the risk of occupational injuries, but also often results in inaccurate alignment of the mounting holes due to unstable grip, reducing assembly efficiency. It can even cause the lever to slip, leading to component collisions or personnel injuries.

[0003] An adjustable excavator rocker arm support device disclosed in announcement number CN222252263U includes a support rod and an adjusting screw. A flange nut seat is rotatably mounted on the adjusting screw, and the flange nut seat is connected to the top of the support rod. A clamping flange is connected to the top of the adjusting screw, and a rotating handwheel is installed at the bottom. The top of the clamping flange is connected to a rocker arm support via a rotating assembly. This device can support rockers of different models and weights by adjusting the height of the rotating assembly, thereby improving the assembly efficiency and accuracy of excavator rocker arms, and reducing the risks of manual labor, product corrosion, and other safety hazards.

[0004] However, this adjustable excavator rocker arm support device is not convenient for quick adjustment according to different installation heights during use. Manual adjustment reduces the accuracy of adjustment, increases the labor intensity of workers, and reduces installation efficiency. Utility Model Content

This excavator rocker arm support device, through the setting of the lifting component, when in use, by starting motor one, motor one drives the positive and negative lead screws to rotate. The rotation of the positive and negative lead screws causes the moving arm to move towards the center. The moving arm towards the center causes the moving arm to push the top plate upward. The upward movement of the top plate causes the top plate to drive the support platform to rise and fall, thereby achieving the lifting function. It is convenient to adjust according to different installation heights, reduce the labor intensity of workers, and improve installation efficiency.
