Its main purpose is to meet the water demand of various water-using equipment inside the building and collect and discharge wastewater. It is mainly divided into indoor and outdoor water supply projects and indoor and outdoor drainage projects.

[0003] In order to meet the aesthetic requirements of urban construction, water supply and drainage pipes are buried underground and laid through pre-excavated ditches for waterproofing. When laying the pipes, due to their heavy weight, cranes are often used to move the water pipes into the ditches by suspension.

When grabbing, the hanging mechanism slides in the self-locking groove, and when it is moved to the top of the water pipe body by the crane and is squeezed by the water pipe body so that the limit seat moves upward, the hanging mechanism slides out of the discharge groove on the W-shaped self-locking groove, thereby releasing the hanging connection between the self-locking mechanism and the hanging mechanism, so that in the process of the grabbing mechanism moving upward, the two grabbing hooks are respectively rotated with the two shafts as the axis, so that the water pipe body is grabbed by the two grabbing hooks and the grab plate B. Grabbing the pipe body, after putting the water pipe body into the ditch, the self-locking mechanism is pushed up again by the water pipe body, so that the hanging mechanism is affected by the guiding mechanism and slides into the self-locking groove again by entering the groove, completing the hanging of the self-locking mechanism and the hanging mechanism, so that the two grabbing hooks are opened to facilitate the grabbing of the water pipe body again, without the need to manually arrange the slings, and the three-point clamping and grabbing are completed by using two grabbing hooks and the grab plate B, which can be grabbed according to the diameter of the water pipe. The specific implementation saves time and effort, can quickly complete the grabbing of the water pipe, and improves the efficiency of the pipe delivery operation.

[0017] 2. The utility model limits the swing arm in a rotating state by means of a limit column and a limit plate, thereby preventing the swing arm from excessively rotating and being unable to enter the self-locking groove again. When manual release is required, the handle can be moved to drive the swing arm to rotate, thereby completing the removal of the mounting shaft on the swing arm. The utility model is convenient for maintenance and simple to operate after a fault. BRIEF DESCRIPTION OF THE DRAWINGS
