Abstract
The utility model discloses an umbrella-opening type pipeline tensioning mechanism. The umbrella-opening type pipeline tensioning mechanism comprises a middle shaft (1) and two movable blocks (2), wherein the movable blocks are sleeved on the middle shaft, tensioning devices (3) fixed with the middle shaft are arranged on the movable blocks (2), and at least three groups of tensioning connecting rods (5) for supporting the inner wall of a pipeline are arranged between the two movable blocks. The tensioning connecting rods used for supporting the inner wall of the pipeline, adopting the technical scheme, are uniformly distributed between the two movable blocks by taking the axis of the middle shaft as the reference, drive the hold-up and the drop-down of the tensioning connecting rods along with the movements of the movable blocks, and are adjusted according to the size of the inner diameter of the pipeline, so that the tensioning connecting rods are convenient to adjusted and suitable for pipeline work with different pipe diameters; and the cost of the tensioning tooling is saved, the tensioning tooling is adequately used, the tensioning is firm, and the structure is simple.
Description
Technical field
The utility model relates to a kind of pipeline processing frock, relates in particular to a kind of umbrella support formula pipeline tension mechanism.
Background technology
In the pipeline operations of the industry such as oil, chemical industry, often will cut pipeline, groove etc. processed operation, need to be at working site pipe laying Work machine.Internal expansion type is a kind of canonical form of pipeline operations machinery, its primary structure be axis install can be in pipeline the mechanism of tensioner, make axis firmly be temporarily fixed at the middle shaft position of pipeline, collar extension installation exercise machinery at axis cuts pipeline, the operations such as groove, because the diameter of pipeline varies, for adapting to the operation of different tube diameters, adopt in the existing tensioner technology and differ in size by some groups, fixture block different in size and screw form, axis be equipped with tapering can before and after fixed block and the nut block of regulating, can regulate within the specific limits the height of fixture block, screw and pipeline on the fixture block are close to, axis is fixed in the pipeline.Select suitable one group of fixture block and screw for the pipeline of different tube diameters, therefore a cover mechanical work need to be equipped with some covers fixture block not of uniform size and screw, could adapt to caliber not of uniform size.When a kind of pipeline operations of caliber, remaining fixture block and screw all are in idle state, cause the waste of tension tool, and the tension tool cost is higher.
Summary of the invention
Goal of the invention: the purpose of this utility model is for the deficiencies in the prior art, and a kind of umbrella support formula pipeline tension mechanism that can be suitable for the pipeline of different size internal diameter is provided, and has saved the cost of tension tool, takes full advantage of tension tool.
Technical scheme: in order to realize the foregoing invention purpose, the technical scheme that the utility model adopts is:
A kind of umbrella support formula pipeline tension mechanism, comprise axis, and being sleeved on two movable blocks on the axis, described movable block is provided with the locking device fixing with axis, is provided with the tensioner connecting rod that at least three groups are used for the supporting pipeline inwall between described two movable blocks.More firm for tensioner, can between two movable blocks, be provided with the six group tensioner connecting rods uniform take axis as benchmark.
Every group of tensioner connecting rod comprises three connecting rods that are hinged, and the connecting rod at two ends is hinged with two movable blocks respectively.
Two end links of described tensioner connecting rod are isometric.
The intermediate connecting rod of described tensioner connecting rod is provided with the rubber layer for damping.
Described for the fixing locking device of axis be locking nut, be threaded with axis.
Beneficial effect: the utility model compared with prior art, its beneficial effect is:
The utility model is provided with the tensioner connecting rod that at least three groups are used for the supporting pipeline inwall, be distributed between two movable blocks take the axis of axis as benchmark, movement along with movable block, drive propping up and falling of tensioner connecting rod, according to the internal diameter of the pipeline size adjustment, be convenient to regulate, can adapt to the pipeline operations of different tube diameters, tensioner is firm, and is simple in structure; For the larger pipeline of tensioner length, can many group umbrella support formula pipeline tension mechanisms be set at an axis; Be provided with rubber layer for damping at the intermediate connecting rod of tensioner connecting rod, can stablize pipeline, reduce vibrations;
The utility model has not only been saved the steel of making tension tool, has reduced cost, and has saved again the activity duration of changing tension tool, has improved production efficiency;
Replace screw with the tensioner connecting rod, the contact area of itself and pipe material inner wall is strengthened, to the pressure of tubing, not only increased the reliability of strong bonded when having reduced tensioner, also reduced the distortion that pressure causes pipeline simultaneously.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing, by a most preferred embodiment, technical solutions of the utility model are elaborated, but protection domain of the present utility model is not limited to described embodiment.
As shown in Figure 1, a kind of umbrella support formula pipeline tension mechanism, comprise axis 1, and be sleeved on two movable blocks 2 on the axis, described movable block 2 is provided with the locking device 3 fixing with axis, be provided with the tensioner connecting rod 4 that at least three groups are used for the supporting pipeline inwall between described two movable blocks, described tensioner connecting rod 4 comprises three connecting rods 41 that are hinged, the connecting rod 41 at two ends is hinged with two movable blocks respectively, two end links 41 of every group of tensioner connecting rod are isometric, intermediate connecting rod is provided with the rubber layer for damping, described for the fixing locking device 3 of axis be locking nut, be threaded with axis.
Internal regulation locking nut with umbrella support formula pipeline tension mechanism insertion pipeline 6 is combined firmly intermediate connecting rod 41 with inner-walls of duct, the umbrella support formula pipeline tension mechanism after regulating is installed on the processing equipment 5 together with pipeline.
