[0024] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0025] Working principle: The cycloidal pin reducer motor of the return line head assembly 1 drives the sprocket to rotate, which in turn drives the chain to reciprocate, providing the power basis for the movement of the trolley;

[0026] The intermediate bracket assembly 4 is arranged at intervals along the movement path of the chain, and its steel profile support provides stable support for the entire assembly; the positioning guide wheels are symmetrically arranged on both sides of the top of the steel profile support, maintaining a suitable gap with the side of the chain, which can effectively limit the lateral deviation of the chain during movement, prevent the chain from running off-center due to uneven force or vibration, and ensure that the chain moves along the preset path; the weighing roller is installed in the middle of the top of the steel profile support, in contact with the bottom of the chain, providing support for the chain, and greatly reducing the resistance of the chain movement through rolling friction, making the reciprocating movement of the chain smoother and more efficient;

[0027] The automatic hook-and-unhook assembly 3 is linked to the chain. When the chain moves forward, the hook of the automatic hook-and-unhook assembly 3 hooks onto the force shaft of the trolley and drives the trolley forward. When the chain moves backward, the hook disengages from the trolley, realizing automatic hook-and-unhook and ensuring that the trolley can move forward step by step with the reciprocating motion of the chain.

[0028] The toggle limit switch of the reciprocating limit switch assembly 2 corresponds to the reciprocating path of the chain. When the chain moves to the limit position, it will trigger the toggle limit switch to control the motor to reverse, thereby limiting the reciprocating range of the chain and preventing the chain from running beyond its range.

[0029] The return line tail assembly 5 supports the tail of the chain and works together with the return line head assembly 1 and the intermediate bracket assembly 4 to maintain the overall balance and stability of the chain during reciprocating motion. Through the coordinated cooperation of each component, the chain can stably and efficiently drive the trolley to move forward continuously.
