Description
Technical field
The present invention relates to a kind of oil pipe continuous thermal spraying transport unit, belong to outer surface of pipe fittings protective layer spraying technology field.
Background technology
At present, hot-spraying techniques many employing semi-automation spraying of the slender rectangular tubes such as Coupled tubing, i.e. pipe original place uniform rotation, spraying dolly along tube axis direction translational motion spraying, stop off or spraying one time after, manually fill spray, spray efficiency is lower, and coating quality is difficult to ensure.Adopt the reason of above-mentioned technique have following some: the first, box cupling is different with the external diameter of oil pipe body, conventional transporting mechanism easily roller place occur card pipe or beat, cause spraying process discontinuous; The second, oil pipe is slender rectangular tube, flexible large, easily beats or trembles in rotation process, and coat-thickness can be caused uneven; 3rd, due to the stop of support roller, easily produced spraying leak source or coating uneven phenomenon by spraying pipe fitting point of suppon place.
Summary of the invention
The object of the present invention is to provide a kind of oil pipe continuous thermal spraying transport unit, its can realize Coupled tubing full-automation, continuous print and stable thermal spray process, improve spray efficiency and coating quality.
Concrete technical scheme of the present invention is as follows:
Support work top is provided with left crossbeam, middle cross beam and right crossbeam, three crossbeams is arranged with two row transmission mechanisms.Transmission mechanism is connected to form by oblique coating roller, left rotary shaft, universal coupling, right spindle and sprocket wheel, the relative oblique coating roller in two inclination angles by bearings between left crossbeam and middle cross beam, universal coupling is by bearings between middle cross beam and right crossbeam, and sprocket wheel is connected and fixed on the motor on ground by chain and transmission shaft.
The rotation of self can be converted to the rotation of oil pipe and the translational motion along oil pipe axis by the oblique coating roller of this device, the contact between itself and oil pipe, tubing joint is made to be point cantact, thus ensure thermospray collar oil line continuous and stable by rubbing effect point, avoid card pipe and generation of beating.The hot spray coating high temperature oxidation resisting of oblique coating roller surface, wear-resistant, can increase and frictional force between oil pipe.Universal joint shaft is energy-conservation avoids the decentraction of rotating shaft and the transmission that causes is beated, thus ensures that oil pipe continuously and smoothly runs.Structure of the present invention is simple, and transmission rotating speed is adjustable, transmits steadily, can meet the needs of different size oil pipe continuous thermal spraying.

Embodiment
With reference to Fig. 1 and 2, embodiments of the invention are further illustrated:
Embodiment:
Oil pipe continuous thermal spraying transport unit is made up of support 1, oblique coating roller 2, left rotary shaft 3, middle cross beam 4, motor 5, transmission shaft 6, universal coupling 7, right spindle 8, chain 9, sprocket wheel 10, bearing 11, right crossbeam 12 and left crossbeam 13:
Support 1 work top is provided with left crossbeam 13, middle cross beam 4 and right crossbeam 12, three crossbeams are arranged with two row transmission mechanisms, transmission mechanism is connected to form by oblique coating roller 2, left rotary shaft 3, universal coupling 7, right spindle 8 and sprocket wheel 10, the relative oblique coating roller 2 in two inclination angles is supported between left crossbeam 13 and middle cross beam 4 by bearing 11, universal coupling 7 is supported between middle cross beam 4 and right crossbeam 12 by bearing 11, and sprocket wheel 10 is connected and fixed on the motor 5 on ground by chain 9 and transmission shaft 6.
Surface temperature after oil pipe hot spray treatment reaches more than 800 DEG C, General Purpose Rubber roller can not use under the high temperature conditions, and also easily there is oxidation and decortication under the high temperature conditions in steel roller, therefore, the present invention's oblique coating roller 2 surface spraying has the SiC coating of high temperature oxidation resisting effect, and this coating hardness is high, wear-resistant, roughness is large, and frictional coefficient is high, can ensure that oil pipe continuously and smoothly transmits.
Universal coupling 7 has plural degree of freedom, can realize freely rotating of more than both direction, the transmission caused because of two ends rotating shaft decentraction can be avoided to beat, run with guaranteeing transport unit high efficiency smooth.
The transport unit principle of oil pipe continuous thermal spraying is as follows:
As shown in Figure 2, two power wheels contact with each other with certain pressure, and when motion-work wheel A rotates, follow-up pulley B also rotates because of the effect of frictional force thereupon, and the point of application of frictional force F is at the osculatory place of two power wheels, and direction is the tangential direction of motion-work wheel A.When the axis being parallel of two power wheels, follow-up pulley B is contrary with the turning direction of motion-work wheel A; When there is certain angle in the axis of two power wheels, two power wheels are point cantact, frictional force F can produce two component, component F1 is along the tangential direction of follow-up pulley A, follow-up pulley B is rotated along the direction that motion-work wheel A is contrary, another component F2 is along the axis direction of follow-up pulley B, and make follow-up pulley B produce rectilinear movement, the rotation of motion-work wheel A is just converted to the rotation of follow-up pulley B and the translational motion along axis by such frictional force F.
In the present invention, oil pipe 14 contacts with oblique coating roller 2 with its deadweight, and because the axis direction of oblique coating roller 2 and the axis direction of oil pipe 14 have α angle, therefore oblique coating roller 2 is point cantact with oil pipe 14.When oblique coating roller 2 rotates clockwise, frictional force F can produce two component, one along oil pipe 14 tangential direction, the F1 that makes it rotate counterclockwise, another along oil pipe 14 axis direction, make it linearly to the F2 of left movement, such frictional force just changes rotating clockwise of oblique coating roller 2 into rotating counterclockwise and left-hand translational motion for oil pipe 14.When tubing joint is passed through, be similarly point cantact between oblique coating roller 2 and tubing joint, thus passing through of tubing joint continuous and stable can be ensured, do not affect the operation of thermospray, ensure coating quality.
