Abstract
The utility model relates to a steel pipe connector for producing pipeline outer coatings. The steel pipe connector comprises a steel bar (2) which is bent into a non-closed circle, an inner ring of the steel bar is fixedly connected to a non-closed cylindrical pipe (1) and a non-closed circular platform-shaped pipe (3) gradually shrinking from interior to exterior, the cylindrical pipe (1) and the circular platform-shaped pipe (3) are arranged side by side, and the opening of the steel bar, the opening of the cylindrical pipe and the opening of the circular platform-shaped pipe are located in the same position. The inner sides of the two ends of the opening of the cylindrical pipe or the opening of the circular platform-shaped pipe are symmetrically and fixedly connected with fixedly-connecting nuts (4 and 4'), and a double-end reverse bolt (5) is installed between the two nuts. The inner side of the cylindrical pipe or the inner side of the circular platform-shaped pipe is symmetrically and fixedly provided with two iron blocks (6 and 6'), and the openings of the iron blocks and the opening of the steel bar are staggered. The steel pipe connector can support a steel pipe to be coated, a front pipe and a back pipe can be stably connected in the coating process, the stability of the steel pipes can be ensured in the process of coating, and product quality is guaranteed.
Description
Technical field
The utility model relates to line pipe external coating to be produced, and relates in particular to a kind of steel pipe connector of producing for line pipe external coating.
Background technique
When the manufacturing operation of line pipe external coating relates to the corrosion-inhibiting coating take polyethylene or polypropylene as main raw material, often adopt the form of " twine and tie up ", by steel pipe end-to-end one by one, spiral advances, by equipment such as extruder, machine neck, die head, pressure rollers, after polyethylene or pp material are melted, form banded film, realize adhering in steel tube surface.In operation process, the length of steel pipe is too short, the difference of ovality, coating roller-way low precision is different all may produce before and after two steel pipes situation about misplacing up and down occur, finally affect coating product quality.Can before and after therefore keeping in coating process, two steel pipes be relatively stable, will directly affect coating product quality.
Model utility content
Technical problem to be solved in the utility model is a kind of steel pipe connector of producing for line pipe external coating, can in coating process, two of front and back steel pipe be coupled together, and in assurance coating process, front and back steel pipe is relatively stable.
The technological scheme that the utility model addresses the above problem is as follows:
A steel pipe connector of producing for line pipe external coating, is characterized in that:
Comprise reinforcing bar, described bar bending becomes the circle of non-closure, the frustoconic shape body shrinking gradually from inside to outside of the cylindrical shape body of the affixed non-closure being arranged side by side of inner ring of reinforcing bar and non-closure, the opening of described reinforcing bar, cylindrical shape body and frustoconic shape body is in same position;
The symmetrical affixed nut in inner side at described cylindrical shape body or frustoconic shape body opening two ends, is provided with the reverse bolt of double end between described two nuts;
The inner side symmetry of described cylindrical shape body or frustoconic shape body sets firmly two iron blocks, and the aperture position of described iron block and reinforcing bar staggers mutually.
As further improvement, the position of described iron block and the reinforcing bar opening central angle of 90 ° that staggers.
As preferably, the incline of described frustoconic shape body and the angle of axis are 5 °.
Working procedure of the present utility model and working principle are, before coating operation, cylindrical shape body is inserted to the inside of steel pipe below, cylindrical shape body fully contacts with the inwall of steel pipe, and be subject to propping up steel pipe inner wall after the effect of bolt tensioner, steel pipe connector of the present utility model can be closely connected with a rear steel pipe.While chasing after pipe, operator first puts into roller-way by first pipe, roller-way helical feed, pipe spiral on pipeline advances, when first pipe leaves first paragraph roller-way completely, while entering second segment roller-way, operator puts into first paragraph roller-way by tube head with a rear steel pipe of steel pipe connector, and button is accelerated in manually-operable, improve the rotating speed of first paragraph roller-way, a rear steel pipe is advanced with the speed spiral higher than first pipe, until the frustoconic shape body of the steel pipe connector on a rear steel pipe enters the afterbody of first pipe, now, two tubes is connected device and links together, operating and so forth each follow-up root pipe chases after into last pipe afterbody.On roller-way, all pipe connects before and after all and enters application station, until after coating finishes, pipe continues operation, while running to roller-way sub-material section, operate manually or automatically sub-material section roller-way and improve rotating speed, make last pipe accelerate to leave a rear pipe, because the frustoconic shape body of steel pipe connector is connected not tight with steel pipe inner wall, like this, the pipe linking together is progressively disconnected from each other again, connector is still stayed a rear pipe head, after operation, operator can unscrew bolt, and knock iron block, fech connection device, realizing iterative cycles uses.
Compared with prior art, the utility model can be played a supporting role to steel pipe to be applied, keeps the stable connection of front and back pipe in coating process, guarantees that in coating process, steel pipe is stable, has guaranteed quality of product.In addition, when two of front and back steel pipe links together by steel pipe connector, before and after being sandwiched in, reinforcing bar between two steel pipes, avoided the groove of the end of steel pipe mutually collide and cause damaging.

Fig. 3 is that the A of Fig. 1 is to schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
In conjunction with Fig. 1 to Fig. 4, a kind of steel pipe connector of producing for line pipe external coating, comprise reinforcing bar 2, described bar bending becomes the circle of non-closure, the frustoconic shape body 3 shrinking gradually from inside to outside of the cylindrical shape body 1 of the affixed non-closure being arranged side by side of inner ring of reinforcing bar and non-closure, the opening of described reinforcing bar, cylindrical shape body and frustoconic shape body is in same position.The symmetrical affixed nut in the inner side at described cylindrical shape body or frustoconic shape body opening two ends 4,4 ', is provided with the reverse bolt 5 of double end between described two nuts.
The inner side symmetry of described cylindrical shape body or frustoconic shape body sets firmly two iron blocks 6,6 ', and the aperture position of described iron block and reinforcing bar staggers mutually.As preferably, the position of described iron block and the reinforcing bar opening central angle of 90 ° that staggers.The incline of described frustoconic shape body and the angle of axis are 5 °.
