Spring and a spring pressure hands, three spring spools are connected with each other integral, and intermediate formation one is for placing spray gun
Mesopore, support foot can move axially along spring spool in being movably embedded into spring spool, and spring is arranged on spring spool
And between support foot, being arranged with two axial long slot bores on spring spool, the inner of two axial long slot bores is divided
Do not extend a horizontal long slot bore to same direction, described spring pressure hands passes through two axial long slot bores and through bullet
Spring, spring pressure hands can be pressed into into horizontal long slot bore under two axial long slot bores, thus by spring-compressed, make supporting
Foot inwardly takes in, and the entire length of bearing unit is shortened.
The front end of described support foot is provided with deep groove ball bearing, and this deep groove ball bearing is connected to support foot by straight pin
Front end.
Angle between described horizontal long slot bore and axially long slot bore is less than 90 degree.
In described three spring spools, first spring spool and second spring spool, the 3rd spring spool it
Between be connected by pin, by a set of table chain retaining mechanism between second spring spool and the 3rd spring spool
Being connected, this table chain retaining mechanism includes the journal stirrup being arranged on second spring spool, is arranged on the 3rd spring
Pressure arc on sleeve and a locking pressure hands, one end of locking pressure hands is movably connected with journal stirrup, and the other end connects one
The individual straight pin for being connected with pressure arc snap close, straight pin is cased with plastic sleeve.
Described spring is cylindroid helical-coil compression spring.
Compared with prior art, the present invention has the following advantages that and feature:
1) principle is novel, and structure is ingenious, and the change that can automatically adapt to pipe internal diameter ensures that spray gun is in axle all the time
Line position；
2) install, easy to use；
3) contact with pipe material inner wall as rolling friction, can effectively reduce the abrasion to pipe material inner wall.
Accompanying drawing explanation
Fig. 1, Fig. 2 are the side-looking structural representations of this utility model two different angles of self adaptation supporter；
Fig. 3 is that the A-A of Fig. 2 is to sectional structure schematic diagram.
Detailed description of the invention
Seeing Fig. 1, Fig. 2, Fig. 3, the present invention is the self adaptation supporter of spraying process in pipeline, including three
1,2,3 and spring pressure hands release ring 4 of individual bearing unit；Three bearing units are evenly distributed on same flat
In face and be connected with each other integral, intermediate formation one is for placing the mesopore of spray gun 5, on each bearing unit point
The spring not being provided with the length for regulating this bearing unit presses hands, spring pressure hands release ring to pass through wire drawing respectively with three
Spring pressure palmistry on individual bearing unit is even.
Three bearing units 1,2,3 structure in the present invention is essentially identical, respectively include a spring spool 11,
21,13,23,33 and spring of 12,22,32, spring of 31, support foot pressure hands 14,24,
34, three spring spools are connected with each other integral, and intermediate formation one is for placing the mesopore of spray gun, and support foot is lived
Moving in being inlaid in spring spool and can move axially along spring spool, spring is arranged between spring spool and support foot,
Spring spool is arranged with two axial long slot bores (as shown in Figure 2 25), two axial long slot bores interior
End extends a horizontal long slot bore 16,26,36, horizontal long slot bore and axial long slot bore respectively to same direction
Between angle less than 90 degree.Spring pressure hands passes through two axial long slot bores and through spring, and spring pressure hands can edge
Article two, it is pressed into into horizontal long slot bore under axial long slot bore, thus by spring-compressed, makes support foot inwardly take in, will prop up
The entire length of bearing unit shortens.
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 leads to
Cross straight pin and be connected to the front end of support foot.
In three spring spools in the present invention, first spring spool 11 and second spring spool the 21, the 3rd
It is connected by pin between individual spring spool 31, between second spring spool 21 and the 3rd spring spool 31
Being connected by a set of table chain retaining mechanism, this table chain retaining mechanism includes being arranged on second spring spool
Journal stirrup 28, the pressure arc 38 being arranged on the 3rd spring spool and a locking pressure hands 29, one end of locking pressure hands
Be movably connected with journal stirrup, the other end connect have one for the pressure straight pin that is connected of arc snap close, straight pin is cased with
Plastic sleeve.
Spring in the present invention is cylindroid helical-coil compression spring, in order to improve the centering after supporter loads spray gun,
Consider actual application operating mode, the cylindroid helical-coil compression spring installed is carried out mechanics respectively divide in 3 bearing units
After analysis, the unified size determining spring force, then carry out the type selecting of spring.
The operation principle of the present invention can accompanying drawings as follows:
During work, supporter is loaded on spray gun, press hands to press down on the spring on each bearing unit and then revolve
Enter in the horizontal long slot bore on each spring spool so that supporter can enter in pipeline easily, when entering pipe
Behind road, pull at release ring, 3 the spring pressure hands horizontal long slot bores from spring spool pull out so that 3
Support foot on individual bearing unit is fitted with tube wall, thus serves the work that spray gun carries out centering location automatically
With.Due to the effect of spring in bearing unit, when supporter moves in the duct, though caliber change, supporter
Can also fit tightly with tube wall, it is ensured that spray gun is on tubing axis all the time.
As it has been described above, the supporter of the present invention solves when spraying OCTG inwall, owing to caliber changes
And the problem that the centering that causes is the best, the uniformity of spray-coated film can be significantly improved.And simple in construction, dress
Formula just, is particularly well-suited to the spraying of petrochemical industry pipeline.
