Description
Technical field
The utility model relates to a kind of steel cylinder joint group to circle-supporting device, and specifically a kind of steel cylinder joint group is to quick circle supporting device.Be mainly used in the construction of construction project pipe string.
Background technology
The pipeline section usually needing the steel cylinder joint group of more piece being justified not longer to one-tenth one section in pipeline engineering construction, therefore needed in advance steel cylinder joint to be held round before docking, existing conventional method is that artificial group is right, although also there is some fluid pressure types, mechanical circle supporting device appearance, but it is too huge, heavy all to there is frock, and be contacting of local with steel cylinder joint, adaptability is strong, the shortcomings such as efficiency is low.
Summary of the invention
The purpose of this utility model is to provide a kind of steel cylinder joint group to quick circle supporting device, significantly can raise the efficiency steel cylinder joint group centering, solves the problems referred to above that existing technique exists.
The utility model is by achieving the above object by the following technical solutions: a kind of steel cylinder joint group is to quick circle supporting device, comprise a left side and hold round ring, the right side holds round ring, under hold round ring, hydraulic jack be connected bearing pin, ring is held round and a left side holds round ring under described, the right side holds round ring and connects by connecting bearing pin, the head of hydraulic jack, tail earrings and a left side hold round ring, the right side holds round ring and connects by connecting bearing pin, a left side holds round ring, the right side holds round ring and can rotate around connection bearing pin, hydraulic oil cylinder head, tail earrings also can rotate with being connected between bearing pin, a left side holds round ring, the right side holds round ring and opens gradually under the promotion of hydraulic jack, until top is to steel cylinder joint inwall, when hydraulic jack stroke reaches maximum, steel cylinder joint is held round.A described left side holds round ring, the right side holds round ring, under to hold round ring be 1/3rd annulus.
A described left side holds round ring, the right side holds round ring, under hold round ring doughnut-shaped steel plate between distance be 150 ~ 400mm, width is 10 times of its thickness.
The described external diameter holding round ring equals the internal diameter of steel cylinder joint, and the steel cylinder joint of different-diameter needs to hold round ring with corresponding external diameter, and hydraulic jack can be dismantled and reuse.
The beneficial effects of the utility model are:
1. structure is simple, only has a hydraulic jack, simple to operate, and speed is fast, and efficiency is high;
2. circle supporting device can utilize leftover pieces to make, and easily manufacture, cost is low.
3. circle linear contact lay, circularity is high, and unfitness of butt joint is little and even, is conducive to the quality and the speed that improve follow-up welding job.
4., without the need to the position spot welding outside two joint steel cylinder joint circumferential welds, group saves without crator steel cylinder out, beautiful appearance.
Accompanying drawing explanation
Fig. 1 is that steel cylinder joint group described in the utility model is to the structural representation of quick circle supporting device.
Fig. 2 is that steel cylinder joint group described in the utility model puts into the state of steel cylinder joint to be held round to quick circle supporting device.
To be steel cylinder joint group described in the utility model put into steel cylinder joint to quick circle supporting device to Fig. 3 that steel cylinder is saved the state after holding round.
Be labeled as in figure: a left side holds round ring 1, the right side holds round ring 2, under hold round ring 3, hydraulic jack 4, connect bearing pin 5.
Detailed description of the invention
Below by way of drawings and Examples, the technical solution of the utility model is described further.
Embodiment
As shown in Figure 1, steel cylinder joint group described in the utility model to quick circle supporting device, comprise that a left side holds round ring 1, the right side holds round ring 2, under hold round ring 3, hydraulic jack 4 and connect bearing pin 5, concrete connected mode is as follows:
Hold round under described that ring 3 holds round ring 1 with a left side, the right side holds round ring 2 and connect by being connected bearing pin 5, head, the tail earrings of hydraulic jack 4 hold round ring 1 with a left side, the right side holds round ring 2 and pass through to be connected bearing pin 5 and connect.
A described left side holds round ring 1, the right side holds round ring 2, under hold round ring 3 and form by 12mm steel plate welding processing.
A described left side holds round ring 1, the right side holds round ring 2, under hold round ring 3 and be 1/3rd annulus.
A described left side holds round ring 1, the right side holds round ring 2, under hold round ring 3 all for being welded at cylindrical one piece of curved plate by two pieces of parallel doughnut-shaped steel plates, the distance between two pieces of doughnut-shaped steel plates is 150 ~ 400mm.
A described left side holds round ring 1, the right side holds round ring 2, under hold round ring 3 doughnut-shaped steel plate width be 10 times of its thickness.
As shown in Figure 2, be the pipe line steel shell ring of interior diameter DN1200, rolled steel cylinder joint has local not circle in various degree, under gravity also can ovalize.Need they to be held round by the construction method of steel cylinder joint group described in the utility model to quick circle supporting device, concrete operation step is as follows:
1. determine according to the internal diameter of required group of right steel cylinder joint the external diameter holding round ring, making the external diameter that described circle supporting device holds round ring is φ 1200;
2. will wait that organizing two right steel cylinder joints keeps flat interface alignment, circle supporting device is put in steel cylinder joint, and the circumferential weld that circle supporting device center line saves interface with steel cylinder aligns;
3. to hydraulic jack input pressure oil, hydraulic jack is stretched out by hydraulic pump, a left side holds round ring 1, the right side holds round ring 2 and open gradually under the promotion of hydraulic jack, until top makes steel cylinder joint become round gradually to steel cylinder joint inwall;
4., after the steel cylinder joint that group is right is held round, spot welding steel cylinder joint girth joint is fixed;
5., to hydraulic jack input buffer brake oil, hydraulic jack is return, a left side holds round ring 1, the right side holds round ring 2 and and then return, take out circle supporting device.
