[0002] During the construction of the shaft, in order to facilitate the transportation of impurities generated during the construction inside the shaft, a lifting device is generally used to lift them. However, during the lifting process of the existing lifting device, when impurities or other items are lifted to the wellhead, manual labor is required to pull the lifting rope to move the lifted items to one side of the wellhead. Manual pulling is not only labor-intensive but also has low safety. Moreover, most of the existing lifting devices are connected by hooks. After the hooks are connected, they are prone to shaking due to external forces, causing them to become unhooked. Therefore, a lifting device for shaft construction is urgently needed to solve the above problems. Utility Model Content
