Abstract
The invention discloses a device for horizontally aligning expansion corrugated pipes, and a pipe aligning welding method. The device comprises two clamping mechanisms which are arranged coaxially, horizontally and symmetrically and are used for clamping two horizontal expansion corrugated pipes for corrugated pipe welding, and a driving device drives the clamping mechanisms to rotate through a drive support device. Each clamping mechanism comprises two symmetrical transmission wheels which clamp the expansion corrugated pipes, and a circle of rack which is matched with a driving gear is arranged outside each main transmission wheel; and the interior of each main transmission wheel has an 8-shaped structure which is mutually matched with the section of each expansion corrugated pipe. The device can clamp and rotate two horizontal corrugated pipes so as to keep the welding position always in a flat welding position. The device is used for horizontal pipe aligning operation of the expansion corrugated pipes, the pipe aligning accuracy and efficiency are high and labor intensity is low.
Description
Technical field
The present invention relates to a kind of plant equipment of field of oil drilling, in particularly a kind of expansion ripple Manifold technology between bellows level to pipe unit and to the pipe welding method.
Background technology
The expansion bellows is before welding, and it is right that first-selection need be carried out the groove group, and pipe unit is mainly used in the groove group that solves before the welding to problem.According to the bellows welding sequence, per two sections bellowss need to carry out horizontal butt welding at the scene earlier, are prefabricated into segment length pipe, again with prefabricated long tube and the bellows vertical butt joint of squeezing into the down-hole, carry out the horizontal position welding operation at well head again.Thereby the palpus level is to pipe unit.
Present prior art is carried out on the bearing plane pipe, and employing is manual to pipe, and following deficiency is arranged:
(1) simpler and cruder.
(2) need rotation and mobile expansion bellows in the docking operation, must hand-turned with move, labour intensity is big.
(3) dangerous.
(4) efficient is low.
(5) low to the pipe precision, influence the later welded quality.
Summary of the invention
The object of the invention is researched and developed a kind of expansion bellows level to pipe unit, and the bellows that expands safely and efficiently is to pipe, so that welding.
One of the present invention's expansion bellows level is that realization is like this to pipe unit:
Expansion bellows level of the present invention comprises pipe unit:
That two cover levels are installed with axial symmetry, be used for the clamping device that two horizontal expansion bellowss of clamping carry out the welding of bellows counterpart;
One cover drives the drive unit of described clamping device rotation through driven bracing or strutting arrangement.
Wherein,
Described every suit clamping device comprises the main driving wheel of two symmetries of clamping expansion bellows;
Described main driving wheel outside is the tooth bar that a circle cooperates with driven wheel;
It is fixing that the described main driving wheel of figure-eight knot structure that described main driving wheel inside is with expansion ripple tube section agrees with each other adopts bolt to be connected, and is convenient to installation and removal.
Described drive unit comprises motor, and the motor output shaft two ends respectively are provided with 1 driven wheel respectively.
Described expansion bellows level also comprises two slot type mechanisms that are provided with described main driving wheel and driven wheel symmetry coupling to pipe unit; Be positioned at in-house two driven wheels of slot type respectively with corresponding two main driving wheels engagement of expansion ripple tube grip mechanism.
Described every suit clamping device also has a driven pulley with coaxial two symmetries of described main driving wheel.
Two its directive wheels of support of described each driven pulley configuration.
The described driven pulley outside is smooth circular arc with the directive wheel outside;
Described driven pulley is inner to be the figure-eight knot structure that agrees with each other with expansion ripple tube section.It is fixing that described driven pulley adopts bolt to connect, and is convenient to installation and removal.
Described slot type mechanism and described directive wheel are separately positioned on four the dismountable support platforms that are configured to.
Described bloated bellows clamping device two parts adopt bolt to be fastened on the support platform.
The present invention's two expansion bellows level is achieved in that the pipe welding method
Described method comprises the steps:
(1) adjustment level remains on the straight line drive unit and driven bracing or strutting arrangement to pipe unit;
(2) connect the drive unit line, the debugging driving device motor;
(3) use expansion ripple pipe holding structure clamping expansion bellows, the horizontal centring of adjustment expansion bellows;
(4) welding gun is set, keeps welding gun to fix, starter motor is provided with expansion bellows body rotary speed according to welding condition; The rotation of driven by motor expansion ripple tube grip mechanism, welding gun welds simultaneously, and welding is accomplished, and stops motor.
In other words, level of the present invention is made up of 1 cover drive unit and the driven bracing or strutting arrangement of 2 covers pipe unit.Two horizontal bellowss of this device ability clamping, and make its rotation, thus keep the welding position to be in downhand position or approximate downhand position all the time.
Level has a motor to pipe unit drive unit bottom, and motor provides the power that drives the rotation of expansion bellows.The rotation of motor-driven output shaft, the output shaft two ends are provided with a driven wheel respectively, and output shaft rotates and drives two ends driven wheel rotation.The two ends driven wheel is arranged in the slot type mechanism, and slot type mechanism is arranged on four support platforms that are configured to.Four gears constitute two toothrows wheel by power transmission shaft, are arranged on the support platform.Motor output shaft two ends gear is taken turns with two toothrows on the support platform and expansion ripple pipe holding structure outboard rack cooperates.The rotation of motor output shaft finally drives the rotation of expansion ripple tube grip mechanism.Expansion ripple tube grip mechanism forms for two parts symmetrical structure, is characterized as outer gear, and internal structure figure-eight knot structure and expansion ripple tube section cooperatively interact.It is fixing that expansion ripple tube grip mechanism two parts adopt bolt to connect, after pipe unit is used, but manual teardown.
Level is made up of expansion ripple tube grip mechanism, support platform and support platform upper bearing (metal) the pipe unit slave unit.Except not having tooth bar in the outside, the expansion ripple tube grip mechanism of slave unit expansion ripple tube grip mechanism and drive unit is basic identical.The slave unit expansion ripple tube grip mechanism outside is smooth circular arc, cooperates with the support platform upper bearing (metal), guarantees that the expansion bellows can rotate smoothly.
Outstanding effect of the present invention is
(1) adopt drive of motor, easy and simple to handle.
(2) safety, reliable.
(3) change bellows clamping device anchor clamps, can satisfy Φ 215.9mm, Φ 241.3mm and three kinds of specification bellowss of Φ 311.15mm to the pipe needs.
(4) high to the pipe precision.
(5) efficient is high.
