Abstract
The utility model discloses a heavy caliber pipeline 90-degrees elbow clamping device, comprises a base; two concentric round rails are disposed on the base; a boring/cutting apparatus installation base is mounted on the rails; a movable guide rail is mounted on the base; the elbow is installed on the movable guide rail by a locking device; the locking device is mounted on the movable guide rail, and can move along the circular arc direction of the movable guide rail. The clamping device can realize the metalworking on the inner wall and outer wall of the elbow, guarantee the surface smoothness of the inner and outer wall, enables the heavy caliber elbow to be used in nuclear industry, and guarantee the safety of nuclear conveying pipelines.
Description
Technical field:
The utility model relates to the process technology of 90 ° of elbows of a kind of large diameter pipeline, relates in particular to the fixture technology of 90 ° of elbows of a kind of large diameter pipeline.
Background technology:
The large-diameter centrifugal casting pipeline can be used for the employed high alloy conversion tube of petroleum chemical industry, concetrated pipe and cracking of ethylene pipe etc., and the conveyance conduit of nuclear power plant is used.This pipeline in course of conveying because the variation in geographical position, in process of deployment, must use 90 ° of elbows, for the heavy caliber straight pipeline, present process technology is full maturity, and also do not possess this technology now for the process technology of bigbore elbow, it now mainly is the surface smoothness that satisfies elbow interior wall by the technology that improves casting, adopt the metalworking technology to process the part that the elbow two ends cooperate with straight tube then, as boring endoporus etc., other inner wall section and excircle part for elbow can't be processed, in case the fineness of elbow does not reach certain requirement, damping phenomena can appear when pumped (conveying) medium, choking phenomenon can occur after time is long, the conveyance conduit of nuclear power plant is particularly important, and inside and outside wall must reach the requirement of certain surface roughness by processing.
The utility model content:
The utility model purpose is to provide a kind of clamping device of novel 90 ° of elbows of large diameter pipeline, come the inwall and the cylindrical of elbow are processed by this clamping device, improve the surface smoothness of elbow interior wall, avoid when pumped (conveying) medium, damping phenomena can occurring.
The utility model is achieved in that the clamping device of 90 ° of elbows of a kind of large diameter pipeline, comprise base, it is characterized in that: two concentric circuit orbits are arranged on described base, bore hole and topping machanism mounting seat are installed on the described track, described two bases move on described track, one movable guiding rail is installed on described base, described movable guiding rail moves around by the diametric(al) that acts on described track of drive unit, elbow is installed on the described movable guiding rail by locking device, described locking device is sleeved on the described movable guiding rail, and this locking device can move in described movable guiding rail upper edge circular arc direction.
The utility model compared with prior art has following advantage:
1. because the mounting seat of bore hole and topping machanism is installed on this clamping device, can realize the metalworking of the inner and outer wall of elbow by this device, guarantee the surface smoothness of elbow inside and outside wall, large caliber bend can be used on nuclear industry, guarantee the safety of nuclear conveyance conduit.
2. this device is provided with movable guiding rail, and movable guiding rail moves under the effect of drive unit, can realize the deflection processing of elbow.
