Description
Technical Field
The invention relates to the field of pipeline disassembly, in particular to a special assembly for disassembling a threaded connecting pipe of a deep-well pump.
Background
The pipeline from the deep-well pump to the ground is composed of a plurality of sections of steel pipes, the steel pipes are in threaded connection, and when the deep-well pump is overhauled, the pipeline needs to be lifted section by section and detached. The diameter of the pipeline is large, so that the matched large pipe tongs are few, and the large pipe tongs are heavy, so that the maintenance personnel are difficult to operate and use; in addition, the lifted pipeline is difficult to fix, and the pipeline and the deep well pump which are not lifted out are easy to fall into the bottom of the well. If the deep-well pump and the pipeline are integrally hoisted by using the automobile crane, the automobile crane with a larger tonnage needs to be rented because the pipeline is longer, the occupied overhaul field is large, the renting cost is high, and the deep-well pump is not suitable for the deep-well pump with a small overhaul field.
In order to solve the above problems, we have always sought an ideal technical solution.
Disclosure of Invention
The invention aims to overcome the defects of the prior art, and provides a special assembly for disassembling a threaded connecting pipe of a deep-well pump, which has the advantages of simple structure, small occupied space and convenience in use.
The technical scheme adopted by the invention is as follows: the utility model provides a deep-well pump threaded connection pipe dismantles special external member, it includes a support frame and two holding framves, and the support frame is used for laying on well head ground, and two holding framves are used for two sections adjacent threaded connection pipe of centre gripping respectively, and wherein, the holding frame that is located the below is laid on the support frame. The lower clamping frame is arranged on the support frame and bears the weight of the deep-well pump and the pipeline, and the threaded connection between the two sections of pipelines can be unscrewed by rotating the upper clamping frame.
The clamping frame comprises a connecting plate and two clamping arms, one ends of the two clamping arms are hinged to the connecting plate respectively, the other ends of the two clamping arms are locked through a detachable connecting piece, each clamping arm comprises a clamping rod and an inner surface which are arc-shaped clamping pieces, the clamping rod and the inner surface are fixedly connected with the clamping arms respectively, the two clamping pieces form a hoop relatively, the diameter of the hoop is matched with the diameter of a pipeline, and friction grains are arranged on the inner surface of each clamping piece. When the clamping frame is used, the two clamping arms are unscrewed to clamp the pipeline between the two clamping parts, and the other ends of the two clamping arms are locked by detachable connecting parts such as hasps, screws, bolts and the like to clamp and fasten the pipeline.
As a further improvement of the technical scheme, the other ends of the two clamping arms are locked through screws. The other ends of the two clamping arms are respectively provided with a threaded hole and are locked through a screw rod; the screw rod can be connected with two locking nuts again, the locking effect is good, the structure is simple, and the use is convenient.
As the further improvement of the technical scheme, the supporting frame is provided with a clamping groove for placing two holding rods corresponding to the clamping frame, the clamping frame is limited, and the clamping frame is prevented from moving.
Compared with the prior art, the invention has the following beneficial effects:
the pipeline is disassembled by adopting two clamping frames and one supporting frame, the structure is simple, the use is convenient, and the occupied space is small.

Fig. 1 is a schematic structural view of the present invention.
In the figure, 1, a connecting plate, 2, a clamping arm, 21, a holding rod, 22, a clamping piece, 3, a supporting frame and 4, a screw rod.
Detailed Description
The technical solution of the present invention is further described in detail by the following embodiments.
As shown in fig. 1, a special assembly for disassembling a threaded connecting pipe of a deep well pump comprises a support frame 3 and two clamping frames, wherein the support frame 3 is used for being placed on the ground of a well head, the two clamping frames are respectively used for clamping two adjacent sections of threaded connecting pipes, and the clamping frame positioned below is placed on the support frame 3; the clamping frame comprises a connecting plate 1 and two clamping arms 2, one ends of the two clamping arms 2 are hinged to the connecting plate 1 respectively, threaded holes are formed in the other ends of the two clamping arms 2 respectively, the two clamping arms are locked through a screw rod 4, and two locking nuts are further connected to the screw rod.
Each clamping arm 2 comprises a holding rod 21 and a clamping piece 22 with an arc-shaped inner surface, and the supporting frame 3 is provided with clamping grooves for placing the two holding rods 21 corresponding to the clamping frames. The two clamping pieces 22 are opposite, and the inner surfaces of the clamping pieces 22 are provided with friction lines.
In the specific implementation, the up and down directions are the descriptions of the relative positions of the structures in the drawings, and the direction perpendicular to the paper surface of fig. 1 is the main view direction.
The using method comprises the following steps:
firstly, a support frame 3 is erected above a well head, a chain block is hung on the support frame 3, the pipeline and a deep well pump are hoisted by the chain block, a first section of pipeline and a second section of pipeline which are counted from top to bottom are respectively clamped by two clamping frames, the clamping frames which are used for clamping the second section of pipeline are placed on the support frame 3, and a holding rod 21 is clamped in a corresponding clamping groove of the support frame 3.
And secondly, two operators respectively hold the holding rods 21 of the clamping frames on the first section of pipeline and rotate to remove the first section of pipeline from the pipeline, and then the clamping frames on the first section of pipeline are removed. When the pipeline is rotated, if the pipe diameter of the pipeline is smaller, one operator can operate the pipeline; if the pipe diameter of the pipeline is larger, operators can be additionally arranged to support the clamping frame or the supporting frame arranged on the supporting frame so as to prevent the supporting frame from moving under stress.
And thirdly, hoisting the rest pipelines upwards by using a chain block to enable the clamping frame originally arranged on the support frame 3 to move upwards along with the second section of pipeline, clamping the third section of pipeline by using the clamping frame disassembled in the second step and arranging the third section of pipeline on the support frame, and repeating the steps until the underground pipeline is completely disassembled.
Finally, it should be noted that the above examples are only used to illustrate the technical solutions of the present invention and not to limit the same; although the present invention has been described in detail with reference to preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention; without departing from the spirit of the present invention, it is intended to cover all aspects of the invention as defined by the appended claims.
