Abstract
The utility model relates to a novel multi-stage serial diameter reducing machine for circular pipes, which compresses and stretches circular pipes of various materials with diameters which need to be reduced through the adoption of a plurality of stages of roller groups stage by stage. The synchronous collaborative work of each stage of the roller group can be realized through a frequency conversion speed adjusting motor. The utility model has the advantages of low power consumption, stepless speed variation, automatic speed adjustment, etc. The utility model is very practical on various construction sites, particularly in the aspect of the construction of the lining and the spread of inner corrosion-resistant plastic pipes of buried pipelines and submarine pipelines in the petroleum engineering.
Description
The utility model relates to a kind of novel plural serial stage tandem type pipe size reducing machine, and it is the creationary design to mechanical type pipe size reducing machine.It mainly is by adopting the multistage roll extrusion wheels pipe of the various materials that need undergauge that compresses step by step, stretches, and realizes the synchronous synergetic work of roll extrusion wheels at different levels by frequency control motor.
At present, job site in all kinds of engineerings, especially all kinds of petroleum pipelines in the oilfield engineering, all need to carry out work such as all kinds of anticorrosion, leakproofs, scale removal and reparation in putting into operation preceding or putting into operation, its workload is big, labour intensity is big, the construction period is long and need all multifactor operating efficiency of construction and benefits of enterprise of having reduced widely such as manpower is many.In recent years, the international petroleum tissue stipulates clearly that to submarine transport oil pipeline must apply anti-corrosion pipe (as polyethylene pipe) at the pipe interior lining can use.Therefore, to can the corrosion-resistant plastic tube (as polyethylene pipe) how to serve as a contrast the problem of applying in oil pipeline and become construction key in the oilfield engineering.Report according to data from abroad, though there is a kind of equipment that can carry out the undergauge stretching to polyethylene pipe in the U.S., but its complex structure, manufacturing cost height, make the user forbidding, what especially the Power Drive Unit of this equipment adopted is hydraulic control, operation easier is big, control accuracy is not high, has brought many inconvenience to site operation.
The purpose of this utility model provides a kind of plural serial stage tandem type pipe size reducing machine with regard to being to avoid above-mentioned the deficiencies in the prior art part, it had both overcome the Power Drive Unit of size reducing machine because the operation inconvenience that hydraulic control brought, but the distance of shaft centers of the adjusting rolling wheel of maneuverability and unload the wheel rim that changes rolling wheel again, thereby realize the undergauge purpose of all kinds of Stretch material pipes.This undergauge device is a kind of plural serial stage tandem type pipe size reducing machine, and it is to be made of multistage roll extrusion wheels, and its major technology characteristics are that multistage roll extrusion wheels are to be in series successively; And every grade of roll extrusion wheels are to be symmetrical arranged at grade by three groups of active rolling wheels and three groups of driven rolling wheels, its each rolling wheel is installed in respectively on the axle bed that can adjust distance of shaft centers, and becomes 60 degree angle settings by the order of active rolling wheel and driven rolling wheel successively.
Accompanying drawing 1 is the structural representation of roll extrusion wheels of the present utility model.
Accompanying drawing 2 is overall structure side view of the present utility model.
Accompanying drawing 3 is the structural representation of the rolling wheel of adjustable distance of shaft centers of the present utility model.
Accompanying drawing 4 is the structural representation of changeable type wheel rim of the present utility model.
The drawing of accompanying drawing is described as follows:
1-chopped-off head roll extrusion wheels 2-machine shell 3-Hooks coupling universal coupling 4-gear-box
5-final stage roll extrusion wheels 6-motor 7-variable-frequency governor 8-calibrator
9-bedplate 10-is the driven rolling wheel of rolling wheel 11-bevel gear 12-initiatively
13-core wheel 14-wheel shaft 15-axle bed 16-screw
17-leading screw 18-bearing block 19-wheel rim
In order to realize above-mentioned purpose of the present utility model better, designer of the present utility model is that the wheel rim with rolling wheel is designed to detachable changing, and can mesh into a full circle fully; The diameter of its each wheel rim then is that the percentage elongation according to want undergauge changes step by step; Power for every group of active rolling wheel then adopts frequency control motor to realize Collaborative Control; The port of export of final stage roll extrusion wheels be provided with can make undergauge after the calibrator of heating of pipe typing.
Come enumeration design feature of the present utility model below in conjunction with accompanying drawing.
In actual design with in making, designer of the present utility model adopts six grades of roll extrusion wheels to connect, every grade of roll extrusion wheels then are designed to three groups of initiatively rolling wheel and three groups of driven rolling wheels, and be symmetrical arranged at grade, its each rolling wheel is installed in respectively on the axle bed that can adjust distance of shaft centers, and becomes 60 degree angle settings by the order of active rolling wheel and driven rolling wheel successively; In order to guarantee the uniformity of speed governing, drive three motors that parameter is identical simultaneously with a cover frequency control motor; For overcome pipe behind the undergauges at different levels advance linear velocity difference and guarantee that it can freely advance behind undergauge, the designer also changes the wheel rim of rolling wheels at different levels according to the undergauge percentage of elongation of required undergauge pipe, this wheel rim can freely unload as required and change; In order to guarantee applicability to the different tube diameters pipe, also wheel shaft and the core wheel with rolling wheel is installed on the axle bed that can move forward and backward, making only needs rotational fixation to drive at the leading screw on the bearing block that screw moves forward and backward on the axle bed in use, realizes changing arbitrarily the purpose of rolling wheel distance of shaft centers.Like this, motor rotates roll extrusion wheels at different levels by the bevel gear on the splined shaft by Hooks coupling universal coupling driven gear case again, thereby realizes the purpose to the pipe undergauge.Because all active rolling wheels all are under the control of same variable-frequency governor,, demonstrate fully convenient, the accurate and errorless characteristics of speed governing so can realize the rotating speed unanimity of roll extrusion wheels at different levels automatically.
The utility model is reasonable in design, simple in structure, easy to operate, has low, the stepless change of energy consumption The advantages such as speed, automatic speed regulation, its each parts can be regulated and detachable mode of changing owing to adopting, so make Long with the life-span, overall performance improves. In all kinds of job sites, buried in petroleum works especially The lining of the interior anti-rot plastic pipe of pipeline and submarine pipeline applies the construction aspect, have its unique advantage and Great market prospects.
