Pipe screw thread is a kind of special cone seal screw thread, its integrality and spatter property are directly related to the success or failure for being drilled well operations.
Since Jing Qianduo deposits in outdoor place to casing from dispatching from the factory to entering, and the resting period is longer, during this period of time casing by
The factors such as wind, rain beat, solarization influence, and casing threads surface is easily stained with the foreign matters such as booty, hard particles object, if in connection spiral shell
These foreign matters are not cleaned up when line, influence the performances such as leakproofness and the bonding strength of screw thread, cause security risk to underground.Institute
With in the drilling well preparation stage, cleaning screw thread is one of most important preparation, but the cleaning method of casing threads also compares at present
It is more original, it is mainly wiped by hand with wire brush and cotton, time-consuming and laborious not say, effect also cannot be guaranteed.
Summary of the invention
It is clear to solve existing casing threads the purpose of this utility model is to provide a kind of sleeve external thread cleaning device
Wash problem time-consuming, laborious, that effect is poor.
To achieve the above object, the utility model provides a kind of sleeve external thread cleaning device comprising shaft, righting
Device and cleaning assembly, the drive end of the shaft are equipped with mechanical connection hole, and the centralizer is rotatable to be connected to described turn
The driven end of axis, the cleaning assembly include support rod, adjusting rod and cleaning brush, and described turn is fixed in described support rod one end
Axis is equipped with the perforation of adjusting in the other end of the support rod, and the adjusting rod is moveably secured to the perforation, and institute
The one end for stating adjusting rod is fixed with nut, and the other end of the adjusting rod is fixed with the cleaning brush, the bristle of the cleaning brush
It is arranged inwardly, spring is equipped on the cleaning brush to the adjusting rod between the support rod.
Wherein, the cleaning assembly is equipped with multiple, and multiple cleaning assembly are circumferentially uniformly arranged along the shaft.
Wherein, multiple cleaning brush are arranged along the axile displacement of the shaft.
Wherein, there are two the cleaning assembly is set, two cleaning assembly are circumferentially symmetrical arranged along the shaft.
Wherein, the spring is compressed spring.
Wherein, the support rod is detachably secured to the shaft.
Wherein, the centralizer is detachably secured to the shaft.
The utility model has the advantages that
Sleeve external thread cleaning device provided by the utility model, power source (pneumatic impact spanner) pass through mechanical connection Kong Yuzhuan
Axis is connected, and to provide machine power, cleaning operation is made to save manpower, centralizer guarantees steady when shaft and cleaning assembly rotate
Fixed, the spring in cleaning assembly makes the cleaning brush moment be close to screw thread, ensure that the active force between cleaning brush and screw thread, improves
The effect of cleaning, generally saves the time, achievees the purpose that time saving and energy saving effect is good.
Detailed description of the invention
Fig. 1 is the sleeve external thread cleaning device structural schematic diagram that embodiment 1 provides.
Fig. 2 is the axonometric drawing of Fig. 1.
In figure: 1- shaft, 2- centralizer, 3- support rod, 4- adjusting rod, 5- nut, 6- cleaning brush, 7- spring, 8- are mechanical
Connecting hole.
Specific embodiment
The following examples illustrate the utility model, but is not intended to limit the scope of the present invention.
Embodiment 1
Embodiment 1 provides a kind of sleeve external thread cleaning device, as illustrated in fig. 1 and 2 comprising shaft 1, centralizer 2
And cleaning assembly, the drive end of shaft 1, which is equipped with, is mechanically connected hole 8, the rotatable driven end for being connected to shaft 1 of centralizer 2,
Maximum outer circle and the internal surface of sleeve pipe of centralizer 2 fit closely, and cleaning assembly includes support rod 3, adjusting rod 4 and cleaning brush 6, branch
Shaft 1 is fixed in 3 one end of strut, is equipped with the perforation of adjusting in the other end of support rod 3, adjusting rod 4 is moveably secured to
Perforation, and one end of adjusting rod 4 is fixed with nut 5, the other end of adjusting rod 4 is fixed with cleaning brush 6, the bristle court of cleaning brush 6
Interior setting, is equipped with spring 7 on cleaning brush 6 to the adjusting rod 4 between support rod 3, and spring 7 is compressed spring 7.
In use, pneumatic impact spanner (drilling team is spare) is connect by being mechanically connected hole with shaft 1, centralizer 2 is inserted into casing
Interior, centralizer 2 and internal surface of sleeve pipe are fitted close, and guaranteeing will not be eccentric when shaft 1 and cleaning assembly rotate, and pass through pneumatic impact spanner band
Turn axis 1 rotates, to make cleaning assembly around sleeve rotating, cleaning brush 6 completes cleaning to the external screw thread of cannula tip, and operation saves
Shi Shengli, cleaning speed is fast, and under the action of spring 7, cleaning brush 6 is close to casing threads, and cleaning dynamics are strong, and cleaning effect is good.
Since casing threads is taper thread, it is different in the starting point of screw thread and the nominal diameter of trailing end, needs in the process of cleaning
The moment is wanted to adjust the position of cleaning brush 6, to guarantee that 6 moment of cleaning brush is close to screw thread, the sleeve external thread of the present embodiment cleans dress
It sets, the design of spring 7 is so that whether in cleaning screw initial thread end or the trailing end of screw thread, cleaning brush 6 can be tight always
Thread surface is pasted, cleaning effect is good, and does not need the position for adjusting cleaning brush 6 at any time, facilitates operation.
In the present embodiment, cleaning assembly is equipped with multiple, and multiple cleaning assembly are circumferentially uniformly arranged along shaft 1, Duo Gesuo
The axile displacement that cleaning brush 6 is stated along the shaft 1 is arranged.
