Detailed Description

The technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiment of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and all other embodiments obtained by those skilled in the art without any inventive work are within the scope of the present invention based on the embodiments of the present invention.

Example 1:

referring to fig. 1-4, an oil pipe descaling device for oil field development comprises a power shaft rod 1, an adjustable support fixedly connected to the outer side of the power shaft rod 1, a plurality of cleaning tools 5 fixedly connected to the periphery of the adjustable support, the plurality of cleaning tools 5 are arranged on the periphery of the power shaft rod 1 in an annular array, and the distance between the power shaft rod 1 and the cleaning tools 5 is adjustable.

At the moment, when the device is placed into the oil pipe, the distance between the power shaft lever 1 and the cleaning cutter 5 is adjusted through the adjustable support, so that the distance between the power shaft lever 1 and the cleaning cutter 5 is smaller than the radius of the oil pipe, a larger mounting gap is generated between the device and the oil pipe, and the device can be mounted into the oil pipe more simply;

after the device gets into oil pipe inside, adjust the interval between power axostylus axostyle 1 and the clearance cutter 5 once more, make the inner wall that clearance cutter 5 and oil pipe right suit, then rotate power axostylus axostyle 1 and drive clearance cutter 5 and rotate, alright clear up in order letting clearance cutter 5 to the dirt of oil pipe inner wall to great reduction the degree of difficulty of clearance.

As shown in fig. 1-2, the adjustable bracket includes a plurality of sets of support rods 2 arranged in an annular array around the power shaft rod 1, the number of each set of support rods 2 is preferably two, the outer side of each support rod 2 is connected with a sliding sleeve 3 in a sliding manner, one side of each set of sliding sleeve 3 away from the power shaft rod 1 is fixedly connected with a cleaning tool 5, and the outer side of the power shaft rod 1 is fixedly connected with a reinforcing component for limiting the adjusted sliding sleeve 3;

at this moment, when clearance cutter 5 is adjusted to needs, open the reinforcement subassembly, no longer let the reinforcement subassembly carry on spacingly to sliding sleeve 3, then at the outside slip sliding sleeve 3 of bracing piece 2, alright adjust the interval between power axostylus axostyle 1 and the clearance cutter 5, adjust and use the reinforcement subassembly to carry on spacingly to sliding sleeve 3 after accomplishing, alright fix with the interval between power axostylus axostyle 1 and the clearance cutter 5.

Simultaneously, adjust the position of clearance cutter 5 for simpler, the outside of bracing piece 2 just is located and has cup jointed return spring 4 between power axostylus axostyle 1 and the sliding sleeve 3, when the device installation carries out oil pipe's inside, bracing piece 2 can promote sliding sleeve 3, let sliding sleeve 3 drive clearance cutter 5 remove towards the direction that is close to the oil pipe inner wall, make power axostylus axostyle 1 automatic be located the intermediate position of oil pipe, thereby reduce the degree of difficulty of installation.

Referring to fig. 1 and 3, in order to fix a plurality of sliding sleeves 3 simultaneously, the reinforcing component includes a threaded ring 7 fixedly connected to the outer side of the power shaft rod 1, the outer side of the threaded ring 7 is connected with a threaded sleeve 11 through threads, and the outer side of the threaded sleeve 11 is fixedly connected with a sliding limiting frame 8, at this time, when the sliding sleeve 3 needs to be fixed, the threaded sleeve 11 is rotated at the outer side of the threaded ring 7, because the threaded sleeve 11 is connected with the threaded ring 7 through threads, the threaded sleeve 11 drives the sliding limiting frame 8 to move horizontally when rotating until the sliding limiting frame 8 abuts against the sliding sleeve 3, and the sliding sleeve 3 is fixed.

And, in order to effectively avoid the thread-off phenomenon of the threaded sleeve 11, the stability of the lifting device, the outside of the threaded ring 7 is located between the sliding limiting frame 8 and the sliding sleeve 3 and is also fixedly connected with the fixing frame 6, the fixing frame 6 is slidably connected with a plurality of limiting ejector rods 9 matched with the sliding sleeve 3, at the moment, when the sliding limiting frame 8 slides, the limiting ejector rods 9 can be extruded, the limiting ejector rods 9 are moved towards the end close to the sliding sleeve 3, until the end of the limiting ejector rods 9 is abutted against the sliding sleeve 3, and the sliding sleeve 3 is fixed.

Here, in order to promote the area of contact of spacing ejector pin 9 and sliding sleeve 3, further hoisting device's stability, spacing groove 10 has been seted up to one side that spacing ejector pin 9 is close to sliding sleeve 3, and the shape of spacing groove 10 is the V font, can let spacing ejector pin 9 and sliding sleeve 3 remain two contact points throughout through the shape design of spacing groove 10 to great hoisting device's stability.

Referring to fig. 4, in order to further improve the cleaning performance of the cleaning tool 5, we choose to convert the horizontal shearing force into an oblique shearing force, at this time, the horizontal section of the cleaning tool 5 is a zigzag formed by a plurality of right angles, and the side of the cleaning tool 5 away from the power shaft 1 is arc-shaped.

When in use: when the device is placed into an oil pipe, the distance between the power shaft lever 1 and the cleaning cutter 5 is adjusted through the adjustable support, so that the distance between the power shaft lever 1 and the cleaning cutter 5 is smaller than the radius of the oil pipe, a larger mounting gap is generated between the device and the oil pipe, and the device can be mounted into the oil pipe more simply;

after the device enters the interior of an oil pipe, the distance between the power shaft lever 1 and the cleaning tool 5 is adjusted again to enable the cleaning tool 5 to be matched with the inner wall of the oil pipe pair, then the power shaft lever 1 is rotated to drive the cleaning tool 5 to rotate, so that the cleaning tool 5 can clean dirt on the inner wall of the oil pipe, and the cleaning difficulty is greatly reduced;

meanwhile, through the structural design of the cleaning tool 5, the horizontal shearing force generated when the cleaning tool 5 rotates is converted into the oblique shearing force, so that the cleaning performance of the device is greatly improved.

The above description is only the preferred embodiment of the present invention; the scope of the present invention is not limited thereto. Any person skilled in the art should also be able to cover the technical scope of the present invention by replacing or changing the technical solution and the improvement concept of the present invention with equivalents and modifications within the technical scope of the present invention.
