Abstract
The utility model relates to assembly and counterpoint equipment of more than two pipe diameters, in particular to a pipe diameter undamaged assembly ring. The pipe diameter undamaged assembly ring comprises an undamaged assembly ring, wherein a reinforcing rib round ring is arranged at the outer side of the undamaged assembly ring in the radial direction. The pipe diameter undamaged assembly ring has the advantages of being simple in structure, convenient to use and free of influence on the appearance of the outer walls of pipes after the pipe diameters are aligned. The reinforcing rib round ring is welded to the outer side of the undamaged assembly ring in the radial direction, and therefore the intensity of the round ring is reinforced, the round ring is not prone to deformation, and the service life of the round ring is prolonged. The inner diameter of the undamaged assembly ring is larger than the outer diameter of a matched pipe fitting barrel body, so that a wedge is enabled to be plunged between the undamaged assembly ring and the pipe fitting barrel body and plays a role in fixing aligned edges.
Description
Technical field
The utility model relates to a kind of two above calibers and mutually organizes contraposition equipment, relates in particular to the harmless group of a kind of caliber to ring.
Background technology
At present, when the caliber group is carried out contraposition, the general scheme that adopts is welding tooling gantry card on the outer wall of caliber, is stuck in the card of frock gantry, under the effect of frock gantry card and chock with chock, two calibers are positioned in together, then the contact jaw of two calibers carried out spot welding, successful group of finishing caliber is right, is organizing rear, extract chock, then remove frock gantry card.Existingly thisly utilize frock gantry to stick into line pipe directly to organize alignment method, meeting be left a trace at the solder joint of outer wall welding tooling gantry of pipe card after finishing contraposition to remove frock gantry card, affect the outward appearance of pipe, and, before the caliber contraposition, want welding tooling gantry card, to remove frock gantry card after the contraposition, troublesome poeration.
The utility model content
The purpose of this utility model provides a kind of simple in structure, and is easy to use, and the caliber positioning equipment that can not exert an influence to managing the outer wall outward appearance after the caliber contraposition.
The technical solution of the utility model is: the harmless group of a kind of caliber is characterized in that ring: comprise a harmless group to ring, harmless group is provided with a reinforcement annulus to the ring outside.
The beneficial effect of this programme is: simple in structure, easy to use, and after the caliber contraposition, can not exert an influence to pipe outer wall outward appearance.
Further, described reinforcement annulus is welded on harmless group on the ring.
The beneficial effect of above-mentioned further improvement project is: be welded with a reinforcement annulus in annulus outer radial direction, strengthened the intensity of annulus, make annulus not yielding, increase the shelf life of annulus.
Further, the described harmless group of internal diameter to ring is larger than the external diameter of the pipe fitting cylindrical shell paired with it.
The beneficial effect of above-mentioned further improvement project is: harmless group is larger than the external diameter of the pipe fitting cylindrical shell supporting with it to the internal diameter of ring, so that chock can be cut into harmless group playing between ring and the pipe fitting cylindrical shell without the injury fixation.
Description of drawings
Fig. 1 is front view of the present utility model;
Fig. 2 is side view of the present utility model;
Fig. 3 is work schematic diagram of the present utility model.
In the accompanying drawing, the list of parts of each label representative is as follows:
1, harmless group is to ring, and 2, the reinforcement annulus, 3, chock, 4, the pipe fitting cylindrical shell.
The specific embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used for explaining the utility model, is not be used to limiting scope of the present utility model.
Such as Fig. 1, Fig. 2, the harmless group of caliber shown in Figure 3 is to ring, comprise that harmless group is to encircling 1 and chock 3, harmless group is welded with a reinforcement annulus 2 to encircling on 1 the outer radial direction, harmless group is to encircling 1 internal diameter than the large 50mm of external diameter of the pipe fitting cylindrical shell 4 supporting with it, in practice, with harmless group to encircling 1 junction that is enclosed within one group of pipe fitting cylindrical shell 4, with the harmless group of several chocks 3 incisions to encircle 1 and pipe fitting cylindrical shell 4 between the space in, chock 3 is cut tightly so that harmless organize to encircle 1 and pipe fitting cylindrical shell 4 can not arbitrarily move, two pipe fitting cylindrical shell 4 counterpart staggered edge frees and must not arbitrarily moving, then the enterprising spot welding in the slit between two pipe fitting cylindrical shells 4 is fixed, and after welding is finished, takes out chock 3, to can't harm group and take off from pipe fitting cylindrical shell 4 encircling 1, thereby finish welding to this group pipe fitting cylindrical shell 4.
The above only is preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
Claims (3)
1. the harmless group of a caliber is characterized in that ring: comprise a harmless group to ring, described harmless group is provided with a reinforcement annulus to the ring outside.
2. the harmless group of a kind of caliber according to claim 1 is characterized in that ring: described reinforcement annulus is welded on harmless group on the ring.
3. the harmless group of a kind of caliber according to claim 1 is characterized in that ring: the described harmless group of internal diameter to ring is larger than the external diameter of the pipe supporting with it.
