The invention relates to a buffering structure of a windproof zipper. The buffering structure comprises a pair of main boards, wherein the upper ends of the pair of main boards are connected with a zipping ear arranged on a port machine through a pin shaft, and the lower ends of the pair of main boards are connected with an upper connection head of the windproof zipper through an upper pin shaft; holes on the main boards matched with the pin shaft are circular, and holes matched with the upper pin shaft are waist-shaped holes extending downwards along the longitudinal direction of the main boards; a pair of buffering boards is arranged at the inner side of the pair of main boards; holes of the buffering boards matched with the pin shaft and the upper pin shaft are circular; and the rated load of the buffering boards is smaller than that of the main boards. According to the buffering structure of the windproof zipper, the buffering boards are additionally arranged at the inner sides of connection main boards of the windproof zipper and perform a buffering function, so that impact load can be obsorbed, a welding line of a connecting zipping ear of a host of the port machine is protected, and the safety of the windproof zipper is increased.
Description
technical field [0001] The invention relates to a windproof safety device for port machinery, in particular to a buffer structure for a windproof cable. Background technique [0002] Windproof cables are generally used for port machinery such as bridge cranes, quay cranes, portal cranes, tire cranes, etc., to act as a windproof fixation, and many wharfs have typhoons passing by, so windproof cables are even more important. [0003] The windproof cable used for port machinery is generally composed of an upper connector, a middle connector, a threaded connecting rod and a lower connector. The lug plate is connected with the anchor seat of the port to play the role of fixing the port machine in strong wind. [0004] When the above-mentioned windproof cable is in use, the lugs of the lower beam on the main engine of the port machine and the welding seam of the main engine are often pulled apart, which poses a relatively large risk and hidden danger.
