Abstract
The invention discloses a conveying device used for oil pipe continuous thermal spraying. The conveying device is designed for achieving a continuous and stable thermal spraying process with complete automatic coupling of an oil pipe. The conveying device mainly comprises three beams, two rows of transmission devices, a slant coating roller, a left rotation shaft, a universal spindle coupling, a right rotation shaft, a chain wheel, a motor and the like. The three beams are arranged on a support, the slant coating roller and the left rotation shaft are supported between the left beam and the middle beam, and the universal spindle coupling and the right rotation shaft are supported between the middle beam and the right beam. The chain wheel and the motor are connected through a chain and a transmission shaft. The slant coating roller can converse self rotation into the rotation of the oil pipe and rectilinear motion along the axis of the oil pipe, so that the contact among the slant coating roller, the oil pipe coupling and the oil pipe, is point contact. Therefore, the condition that the thermal spraying coupling oil pipe passes through the friction working points continuously and stably is guaranteed and pipe blockage and beating are prevented from occurring. The slant coating roller is high-temperature oxidation resistant and anti-abrasion. The universal spindle coupling can prevent the device from beating in the process of transmission, so that the condition that the oil pipe thermal spray runs continuously and stably is guaranteed. The conveying device used for the oil pipe continuous thermal spraying is simple in structure, and can satisfy the requirements of continuous thermal spraying of oil pipes with various specifications.
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, the hot-spraying techniques of the slender rectangular tubes such as Coupled tubing adopts semi-automatic spraying, i.e. pipe original place uniform rotation more, spraying dolly is along tube axis direction translational motion spraying, and stop off or spray after a time will manually fill spray, spray efficiency is lower, and coating quality is difficult to guarantee.Adopt the reason of above-mentioned technique have following some: the first, box cupling is different with the external diameter of oil pipe body, easily there is card pipe or beat in conventional transporting mechanism, causes spraying process discontinuous at roller place; The second, oil pipe is slender rectangular tube, flexible large, in rotation process, easily beats or trembles, and can cause coat-thickness uneven; The 3rd, due to stopping of support roller, by spraying pipe fitting point of suppon place, easily produced spraying leak source or coating uneven phenomenon.
Summary of the invention
The object of the present invention is to provide a kind of oil pipe continuous thermal spraying transport unit, it can realize Coupled tubing full-automation, continuous and stable thermal spray process, improves 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, is arranged with two row transmission mechanisms on three crossbeams.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 oblique coating roller of this device can convert the rotation of self to the rotation of oil pipe and along the translational motion of oil pipe axis, make its with oil pipe, tubing joint between contact as some contact, thereby what guarantee thermospray collar oil line continuous and stable passes through rubbing effect point, avoids card to manage and the generation of beating.The hot spray coating high temperature oxidation resisting of oblique coating roller surface, wear-resistant, can increase and oil pipe between frictional force.The energy-conservation transmission of avoiding the decentraction of rotating shaft and causing of universal joint shaft is beated, thereby guarantees that oil pipe continuously and smoothly moves.The present invention is simple in structure, and transmission rotating speed is adjustable, transmits steadily, can meet the needs of different size oil pipe continuous thermal spraying.

Fig. 2 is transport unit principle Analysis figure for 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 is comprised 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 with transport unit:
Support 1 work top is provided with left crossbeam 13, middle cross beam 4 and right crossbeam 12, on three crossbeams, be 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, two relative oblique coating rollers 2 in inclination angle are 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 ℃, General Purpose Rubber roller can not be used under hot conditions, and also easily there is oxidation and decortication in steel roller under hot conditions, therefore, oblique coating roller 2 surface sprayings of the present invention have 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 guarantee that oil pipe continuously and smoothly transmits.
The transport unit principle of oil pipe continuous thermal spraying is as follows:
As shown in Figure 2, two power wheels are in contact with one another with certain pressure, and when motion-work wheel A rotates, follow-up pulley B is because of the also rotation thereupon of effect of frictional force, 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 of two power wheels is parallel, the direction of rotation of follow-up pulley B and motion-work wheel A; When there is certain angle in the axis of two power wheels, two power wheels are some contact, 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 contrary direction of motion-work wheel A, another component F2 is along the axis direction of follow-up pulley B, makes follow-up pulley B produce traveling priority, and frictional force F just converts the rotation of motion-work wheel A to the rotation of follow-up pulley B and along the translational motion of axis like this.
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 contacts for putting with oil pipe 14.When oblique coating roller 2 clockwise rotates, frictional force F can produce two component, one along oil pipe 14 tangential directions, F1 that it is rotated counterclockwise, another along oil pipe 14 axis directions, make its F2 along straight line to left movement, frictional force just changes clockwise rotating of oblique coating roller 2 into rotating counterclockwise and left-hand translational motion for oil pipe 14 like this.When tubing joint by time, between oblique coating roller 2 and tubing joint, be similarly and contact, thereby can guarantee passing through of tubing joint continuous and stable, do not affect the operation of thermospray, guarantee coating quality.
