Description
Technical Field
The invention relates to the field of pipeline disassembly, in particular to a special kit 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. Because the pipeline diameter is thicker, the matched large pipe tongs are fewer, the large pipe tongs have large weight, and are difficult to operate and use by maintenance personnel; in addition, the lifted pipeline is difficult to fix, and the un-lifted pipeline and the deep-well pump are extremely easy to drop 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 larger tonnage is required to be rented due to longer pipeline, 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 small overhaul field.
In order to solve the above problems, we have sought an ideal technical solution.
Disclosure of Invention
The invention aims at overcoming the defects of the prior art, and provides a special kit 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 invention adopts the technical scheme that: the utility model provides a special external member is dismantled to deep-well pump screwed connection pipe, it includes a support frame and two clamping frames, and the support frame is used for laying on the well head ground, and two clamping frames are used for the centre gripping adjacent two sections screwed connection pipe respectively, and wherein, the clamping frame that is located the below is laid on the support frame. The clamping frame below is placed on the supporting 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 clamping frame above.
The clamping frame comprises a connecting plate and two clamping arms, one ends of the two clamping arms are respectively hinged with the connecting plate, the other ends of the two clamping arms are locked through a detachable connecting piece, each clamping arm comprises a holding rod and a clamping piece with an arc-shaped inner surface, the holding rod and the clamping piece are respectively fixedly connected with the clamping arms, two clamping pieces relatively form a hoop, the diameter of the hoop is matched with the diameter of a pipeline, and friction lines are arranged on the inner surface of the clamping piece. When the clamping frame is used, the two clamping arms are unscrewed to clamp the pipeline between the two clamping pieces, and then the other ends of the two clamping arms are locked by the detachable connecting pieces such as buckles, 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 by screw rods. Threaded holes are respectively formed in the other ends of the two clamping arms and are locked through screw rods; the screw rod can be connected with two lock nuts again, so that the locking effect is good, the structure is simple, and the use is convenient.
As a further improvement of the technical scheme, the supporting frame is provided with clamping grooves for accommodating the two holding rods corresponding to the clamping frame, and the clamping frame is limited to prevent the clamping frame from moving.
Compared with the prior art, the invention has the following beneficial effects:
two clamping frames and a supporting frame are adopted to disassemble the pipeline, so that the pipeline is simple in structure, convenient to use and small in occupied space.
Drawings
Fig. 1 is a schematic structural view of the present invention.
In the figure, the connecting plate 1, the clamping arm 2, the holding rod 21, the clamping piece 22, the supporting frame 3 and the screw rod 4.
Detailed Description
The technical scheme of the invention is further described in detail through the following specific embodiments.
As shown in fig. 1, a special kit for disassembling a threaded connecting pipe of a deep-well pump comprises a supporting frame 3 and two clamping frames, wherein the supporting frame 3 is used for being placed on the ground of a wellhead, 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 supporting frame 3; the clamping frame comprises a connecting plate 1 and two clamping arms 2, one ends of the two clamping arms 2 are respectively hinged with the connecting plate 1, threaded holes are respectively formed in the other ends of the two clamping arms 2, the clamping frame is locked through a screw 4, and two locking nuts are further connected to the screw.
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 accommodating the two holding rods 21 corresponding to the clamping frames. The two clamping pieces 22 are opposite, and friction lines are arranged on the inner surfaces of the clamping pieces 22.
In the specific implementation, the up and down directions are the directions of the relative positions of the structures in the drawings, and the directions perpendicular to the paper surface of fig. 1 are taken as the main viewing directions.
The using method comprises the following steps:
1. The support frame 3 is arranged above a wellhead, the hand hoist is hung on the support frame 3, the pipeline and the deep well pump are hoisted by the hand hoist, the first section of pipeline and the second section of pipeline which are counted from top to bottom are respectively clamped by the two clamping frames, the clamping frames which are used for clamping the second section of pipeline are arranged on the support frame 3, and the holding rods 21 are clamped in corresponding clamping grooves of the support frame 3.
2. Two operators respectively hold the holding rods 21 of the holding frames on the first section of pipeline and rotate, the first section of pipeline is removed from the pipeline, and then the holding frames on the first section of pipeline are removed. When the pipeline is rotated, if the pipe diameter of the pipeline is smaller, an operator can operate the pipeline; if the pipe diameter is large, operators can be added to support the clamping frame or the supporting frame arranged on the supporting frame, so that the supporting frame is prevented from being stressed and moved.
3. And C, lifting the rest pipeline upwards by using a chain block, enabling the clamping frame originally placed 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 detached in the second step and placing the third section of pipeline on the support frame, and repeating the steps circularly until the underground pipeline is detached.
Finally, it should be noted that the above-mentioned embodiments are only for illustrating the technical scheme of the present invention and are not limiting; while the invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that the present invention may be modified and equivalents substituted for elements thereof; without departing from the spirit of the invention, it is intended to cover the scope of the invention as claimed.
