Description
Technical field
The utility model relates to a kind of heavy-caliber nodular cast iron pipe coupling assembling erecting tools, especially relates to a kind of for installing the erecting tools of heavy-caliber nodular cast iron pipe interface from anchor assemblies.
Background technology
In pipe applications field, what the interface of traditional heavy-caliber nodular cast iron pipe adopted is spigot-and-socket, socket enters bellmouth by the compression cushion rubber be arranged in bellmouth, realizes the sealing of two segment pipes in junction, also namely complete the installation exercise of two segment pipes by cushion rubber.But this kind of interface is simple pipeline end thinner for a segment pipe is inserted the thicker pipeline end of another segment pipe, does not possess the vibrational power flow that constraint two segment pipe moves axially, does not thus also possess axial constraint ability.Under the effect that liquid internal pressure and axial flow rub, two segment pipes will because of the trend of the effect generation axial slip of long-term liquid stream at interface.For preventing two segment pipe slippages, traditional way is that each pipeline junction cement mortar in pipeline or concrete buttress fix pipeline two ends, improves pipeline safety coefficient of utilization.
Along with ductile iron pipe is applied to state key water delivery, Gas transmission project more and more widely, and export international market in a large number, in industry, each enterprise development has the Novel ball graphite cast iron pipe of interface from anchor structure, and because of it possess pipeline axial move restraining force and be applied to passing through, turn to, the various special engineering location such as abrupt slope.In prior art as shown in Figure 4, the interface of Novel ball graphite cast iron pipe is from anchor structure, mark 8' is left side pipe joint end tube wall, mark 9' is right side pipe joint end tube wall, mark 10' is right side pipe joint end bell end wall, mark 11' be from the support cushion rubber of anchor assemblies, mark 12' be from the rear gear block of anchor assemblies, mark 13' be from the front-seat block of anchor assemblies, mark 14' be O-ring seal, shelves note 15' is that the annular be fixed on the pipeline outer wall of left side stops and encloses.Front-seat block 13' and rear gear block 12' respectively by separately independently some blocks to be uniformly distributed along pipeline circumference and to form, rear gear block 12' loads successively and supports the corresponding high spot of cushion rubber 11', installs one piece of front-seat block 13' after every two pieces between gear block 12'.There is provided by the elasticity supporting cushion rubber 11' the power resources that rear gear block is upper and lower and move left and right in work.First rear gear block 12' to be arranged on when mounted and support on cushion rubber 11', then gear block 12' after extruding adjacent two, the space of front-seat block 13' is installed in expansion, gear block 12' after discharging again after loading front-seat block 13', and complete the installation of all front-seat block 13' successively, front-seat block 13', rear gear block 12' are formed under the elastic force effect supporting cushion rubber 11' and closely cooperates.
For heavy-caliber nodular cast iron pipe, because the elastic force supporting cushion rubber 11' is larger, in the installation process of front-seat block 13', need to use the comparatively rear gear block 12' of high thrust extruding and support cushion rubber 11', when not using specialist tools, more than two people or the two people class instrument that simultaneously uses the rod often is needed to prize adjacent rear gear block 12' and just can form enough spaces to install front-seat block 13', not only time-consuming but also require great effort, virtually have impact on operating efficiency and productivity effect.
