Abstract
The utility model discloses a straightening device for remanufacturing pretreatment of waste oil pipes, which comprises a fixed pair roller and a lifting roller, wherein the fixed pair roller and the lifting roller are arranged in a triangle, the lifting roller is arranged above the fixed pair roller, the oil pipe is arranged in the middle of the triangle, the lifting roller is arranged on a lifting frame, the lifting frame is arranged on a lifting mechanism such as a lifting oil cylinder, and the distance between the fixed pair roller is larger than the radius of the oil pipe and smaller than the diameter of the oil pipe; the utility model has the advantages that: simple structure, with low costs, convenient operation has improved work efficiency.
Description
Technical Field
The utility model relates to an oil pipe coalignment, specifically speaking are coalignment that old and useless oil pipe refabrication preliminary treatment was used belong to oil pipe coalignment field.
Background
With the development of international economy, the demand for petroleum and natural gas resources is continuously expanding, and as the price of crude oil is continuously increased, some oil wells with deeper oil layer depth, higher corrosion of hydrogen sulfide and higher exploitation cost are also exploited. In long-term oil extraction operation, the phenomena of eccentric wear, corrosion and scaling of an oil pipe of an oil extraction well can occur, so that the pipe wall is seriously damaged and cannot be used continuously. In the remanufacturing process of the waste oil pipe, pretreatment is usually required, including oil pipe straightening, however, the traditional oil pipe straightening device has a complex structure and higher cost.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model discloses a coalignment that old and useless oil pipe refabrication preliminary treatment used, simple structure, it is with low costs, convenient operation has improved work efficiency.
The technical scheme of the utility model is that:
the utility model provides an aligning device that old and useless oil pipe refabrication preliminary treatment was used, is including fixed pair roller and lift roller, fixed pair roller and lift roller be triangle-shaped and arrange, the lift roller sets up fixed pair roller top, oil pipe set up triangle-shaped's middle part, the lift roller sets up on the crane, the crane sets up on elevating system like lift cylinder, realizes the lift of lift roller through elevating system, the interval of fixed pair roller is greater than oil pipe's radius and is less than oil pipe's diameter to make oil pipe be restricted between fixed pair roller, only can pass along the center pin of self by oneself, the alignment of oil pipe has been realized in the extrusion of rethread lift roller, simple structure, and is with low costs, and convenient operation has improved work efficiency.
Further, the lifting mechanism is arranged on the fixed frame.
Wherein, the fixed pair rollers and the lifting rollers are both in transmission connection with a driving device.
Further, the rotating directions of the fixed counter roller and the lifting roller are opposite.
When the oil pipe straightening machine is used, the lifting roller is lifted to enable the oil pipe to be placed between the fixed pair of rollers, then the lifting roller is lowered to enable the fixed pair of rollers and the lifting roller to rotate, and the oil pipe is straightened in the rotating process.
The utility model has the advantages that: simple structure, with low costs, convenient operation has improved work efficiency.
The present invention will be further explained with reference to the drawings and examples.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Detailed Description
The following description of the preferred embodiments of the present invention is provided for the purpose of illustration and description, and is not intended to limit the invention.
Example 1
As shown in fig. 1, a straightener that old and useless oil pipe refabrication preliminary treatment was used, including fixed pair roller 1 and lift roller 2, fixed pair roller 1 and lift roller 2 be triangle-shaped and arrange, lift roller 2 sets up fixed pair roller 1 top, oil pipe 3 sets up triangle-shaped's middle part, lift roller 2 sets up on crane 4, crane 4 sets up on elevating system like lift cylinder 5, realizes the lift of lift roller through elevating system, the interval of fixed pair roller 1 is greater than oil pipe's radius and is less than oil pipe's diameter to make oil pipe restricted between fixed pair roller, only can pass along the center pin of self, the alignment of oil pipe has been realized to the extrusion of rethread lift roller, and simple structure is with low costs, and convenient operation has improved work efficiency.
The lifting mechanism 5 is arranged on the fixed frame.
Wherein, the fixed pair rollers and the lifting rollers are both in transmission connection with a driving device.
The rotating directions of the fixed counter roller and the lifting roller are opposite.
