Embodiment 1
[0044] refer to figure 1 and figure 2 , the installation device includes two connecting components 2 and a tensioning component 3 for connecting and hoisting the pipeline 1 . The connection assembly 2 includes a sling 21 and a sleeve 22 overlaid on the sling 21. The sling 21 is sleeved on the pipe 1 during use, and the sleeve 22 is placed under the pipe 1. The sleeve 22 is arc-shaped and fits on the pipe 1. The outer wall of the sling 21 can be removed and reused only after the sling 21 is pulled out from the casing 22 after use.
[0045] The stretching assembly 3 includes a movable pulley 31 connected to one of the slings 21, a fixed pulley 32 connected to the other sling 21, and a guide pulley 33, and the sling 21 connected to the movable pulley 31 is sleeved on the pipeline 1 to be inserted. The fixed pulley 32 is provided with a drag cable 34. After the drag cable 34 is pulled out, the fixed pulley 32 is first sleeved on the movable pulley 31, and finally is sleeved on ...

The present application relates to an installation device and a construction method for ductile iron pipes, which include two connecting components and a stretching component for connecting the pipelines, and the stretching component includes a moving pulley connected to one of the connecting components, a movable pulley connected to the other The fixed pulley and the guide pulley of the connection assembly, the fixed pulley is connected with a cable; the cable is drawn out from the fixed pulley, then sheathed on the movable pulley in sequence, and finally sheathed on the lower side of the guide pulley and extends upwards. The movable pulley is provided with a safety component that reduces the risk of slippage of the connected component relative to the pipeline, and the fixed pulley and the guide pulley are also provided with a safety component. The application can relatively conveniently install pipelines, and relatively save manpower and material resources.
Description
technical field [0001] The present application relates to the field of pipeline installation, in particular to an installation device and construction method for ductile iron pipes. Background technique [0002] Ductile iron pipe refers to the pipe made by high-speed centrifugal casting of centrifugal ductile iron machine after casting molten iron above No. 18 with the addition of nodularizer, referred to as ball pipe, ductile iron pipe and ductile cast pipe. It is widely used in urban water supply and gas pipelines. [0003] In the existing related technology, when installing, the "chain-down method" is usually used for installation, that is, after installing hooks, steel ropes, and chains (or electric hoists) at the interface, the pipe is pulled into the installed pipe by manual traction. socket of the pipe. [0004] With regard to the related technologies mentioned above, the inventor believes that in actual operation, as the diameter of the installation pipe increases,...
