The support frame 10 is provided with a rocker arm supporting portion 11 for supporting the rocker arm and a transport connection portion cooperating with the vehicle. The adjustment assembly 20 includes a first adjusting member 21 and a first supporting platform 22. The lower end of the first adjusting member 21 is provided on the support frame 10, and the upper end of the first adjusting member 21 is connected to the lower surface of the first supporting platform 22. The first adjusting member 21 is vertically liftable to drive the first supporting platform 22 to move vertically. The first supporting platform 22 has an initial state and a supporting state that are concave or flush with the rocker arm supporting portion 11.

[0024] The rocker arm installation device provided in this embodiment is applied, and the rocker arm installation device includes a support frame 10 and an adjustment assembly 20. The support frame 10 can support the rocker arm. Specifically, the rocker arm is supported by the rocker arm supporting portion 11 on the support frame 10, and the transportation connection portion on the support frame 10 is connected to the vehicle. In this way, when the rocker arm is placed on the support frame 10, the support frame 10 cooperates with the vehicle, and then the support frame 10 can be transported, ensuring that the rocker arm on the support frame 10 is installed on the coal mining machine. Specifically, the first adjusting member 21 of the adjusting assembly 20 is disposed on the support frame 10, and the upper end of the first adjusting member 21 is connected to the lower surface of the first supporting platform 22. The first adjusting member 21 can be vertically raised and lowered, thereby driving the first supporting platform 22 to move vertically, so that the first supporting platform 22 has an initial state of being recessed in the rocker arm support portion 11 and a supporting state of being flush with the rocker arm support portion 11, so that the adjusting assembly 20 can be used to adjust the height of the rocker arm placed on the support frame 10, thereby facilitating the installation of the rocker arm on the coal mining machine, avoiding the need for multiple people to collaborate to install the rocker arm, and also achieving a positioning function for the installation of the rocker arm, thereby improving installation efficiency. When the rocker arm is placed on the support frame 10, the first supporting platform 22 is in the initial state. When the position of the rocker arm needs to be adjusted, the first adjusting member 21 is vertically raised to drive the first supporting platform 22 to move, so that the first supporting platform 22 can drive the rocker arm to move vertically, thereby facilitating the positioning and installation of the rocker arm on the coal mining machine, thereby improving installation efficiency.
