[0010] By adopting the above technical solution, the pull plate can slide inside the slide groove through the slider. When the pull plate is pulled to the right, the spring is compressed and contracted. After the insertion shaft passes through the clamp, the spring can be released and pushed to the left to complete the reset. The reset insertion plate is then inserted into the slot of the insertion shaft.

[0011] Preferably, the positioning rod is a cylinder, the diameter of the positioning rod is smaller than the inner diameter of the spring, the positioning groove is a circular groove, the positioning groove is connected to the sliding groove, and the length of the positioning groove is smaller than the length of the positioning rod.

[0017] 1. The windproof wedge of this dock gantry crane is equipped with an insert plate. A slider is slidably connected inside the slide groove. A pull plate is fixedly connected to the top of the slider. An insert plate is fixedly connected to one side of the pull plate. The insert plate is inserted into the slot. When in use, pull the pull plate to the right and then insert the shaft through the clamp and the wedge body. After the insert shaft passes through the clamp, release the spring to push the insert plate to the left to reset. The reset insert plate is inserted into the slot of the insert shaft, which can quickly fix the insert shaft and facilitate the installation and removal of the insert shaft.

[0018] 2. The windproof wedge of the gantry crane at the dock is equipped with a positioning rod. The positioning rod is fixedly connected to the inside of the slider near the spring. A positioning groove is opened on one side of the slide. The positioning rod is inserted into the inside of the positioning groove. When the pull plate is pulled to the right, the positioning rod can be inserted into the inside of the positioning groove, and the spring is compressed and contracted. The positioning rod can prevent the spring from bending when compressed and can assist the spring to contract and unfold more stably. Attached Figure Description
