[0015] The utility model provides a steel rope tensioning device for a waterproof cloth trolley. During use, if a chain on one side breaks and the chain cannot be kept tensioned in a straight line, the force storage spring of the outer rocker arm contracts, causing the outer rocker arm to move, and the top of the outer rocker arm is separated from the rotating baffle, but the state of the outer rocker arm on the other side does not change, and it still supports one end of the rotating baffle. The rotating plate will rotate around the rotating baffle axis and gradually separate from the outer rocker arm that has not changed. Under the action of the main spring, the stop pin moves downward and gradually contacts the track. Finally, the stop pin is inserted into the hole on the track, thereby limiting the sliding block After the chain breaks suddenly, a large displacement occurs, and the chains on both sides break. The chain cannot remain tensioned in a straight line, and the force storage springs of the outer rocker arms on both sides shrink, causing the outer rocker arms to move. The tops of the outer rocker arms on both sides are separated from the rotating baffle, and under the action of the main spring, the stop pin moves downward, gradually contacts the track, and finally the stop pin is inserted into the hole on the track, thereby limiting the large displacement of the slider after the chain breaks suddenly. By setting up the overall structure, it is possible to facilitate emergency stopping when the tarpaulin trolley is in use, thereby avoiding damage or falling during heatstroke prevention.
