Described spring is cylindroid helicalcoil compression spring.
Compared with prior art, the present invention has following advantage and disadvantage:
1) principle is novel, and structure is ingenious, and the change that automatically can adapt to pipe internal diameter ensures that spray gun is in axial location all the time;
2) install, easy to use;
3) contact with pipe material inner wall as rolling friction, effectively can reduce the wearing and tearing to pipe material inner wall.
Accompanying drawing explanation
Fig. 1, Fig. 2 are the side-looking structural representations of self adaption supporter of the present invention two different amount;
Fig. 3 is that the A-A of Fig. 2 is to sectional structure schematic diagram.
Embodiment
See Fig. 1, Fig. 2, Fig. 3, the present invention is used for the self adaption supporter of spraying process in pipeline, comprises three bearing units, 1,2,3 and spring pressure hand release ring 4; Three bearing units to be evenly distributed in same plane and to be interconnected integrally, middle formation one is for placing the mesopore of spray gun 5, each bearing unit is respectively equipped with the spring pressure hand of the length for regulating this bearing unit, spring pressure hand release ring is pressed on the spring on three bearing units respectively by wire drawing and is connected.
Three bearing units 1 in the present invention, 2, 3 structures are substantially identical, respectively comprise a spring spool 11, 21, 31, a support foot 12, 22, 32, a spring 13, 23, 33 and spring pressure hand 14, 24, 34, three spring spools are interconnected integrally, middle formation one is for placing the mesopore 6 of spray gun, support foot activity is inlaid in spring spool and can moves axially along spring spool, spring is arranged between spring spool and support foot, spring spool is arranged with two axial slotted holes (as shown in Figure 2 25), article two, a horizontal slotted hole 16 is extended respectively to same direction in the inner of axial slotted hole, 26, 36, angle between horizontal slotted hole and axial slotted hole is less than 90 degree.Spring pressure hand passes through two axial slotted holes and through spring, spring pressure hand can press down along two axial slotted holes and enter horizontal slotted hole, thus by spring-compressed, support foot is inwardly taken in, and the entire length of bearing unit is shortened.
In the present invention, the front end of each support foot is respectively equipped with deep groove ball bearing 17,27,37, and this deep groove ball bearing is connected to the front end of support foot by straight pin.
In three spring spools in the present invention, first spring spool 11 and second spring spool 21, be connected by pin between 3rd spring spool 31, second spring spool 21 is connected by a set of table chain locking mechanism with between the 3rd spring spool 31, this table chain locking mechanism comprises the journal stirrup 28 be arranged on second spring spool, be arranged on the pressure arc 38 on the 3rd spring spool and a locking pressure hand 29, one end and the journal stirrup of locking pressure hand are movably connected, the other end is connected with a straight pin for being connected with pressure arc snap close, on straight pin, cover has plastic sleeve.
Spring in the present invention is cylindroid helicalcoil compression spring, the centering after spray gun is loaded in order to improve supporter, consider practical application operating mode, after respectively mechanical analysis is carried out to the cylindroid helicalcoil compression spring installed in 3 bearing units, the unified size determining spring force, then carry out the type selecting of spring.
Working principle of the present invention can accompanying drawings as follows:
During work, supporter is loaded on spray gun, spring pressure hand on each bearing unit is pressed in the horizontal slotted hole then screwed on each spring spool downwards, supporter is made to enter in pipeline easily, after entering pipeline, pull at release ring, 3 spring pressure hands are pulled out from the horizontal slotted hole spring spool, support foot on 3 bearing units and tube wall are fitted, so just serves the effect automatically spray gun being carried out to centering location.Due to the effect of bearing unit medi-spring, when supporter moves in the duct, even if caliber change, supporter also can fit tightly with tube wall, ensures that spray gun is on tubing axis all the time.
As mentioned above, when supporter of the present invention solves and sprays OCTG inwall, the problem that the centering caused due to caliber change is not good, can significantly improve the uniformity of spray-coated film.And structure is simple, easy to assembly, be specially adapted to the spraying of petrochemical industry pipeline.
