Description

Technical Field

[0001] The utility model relates to the technical field of continuous oil pipes, in particular to a fixing assembly for a petroleum continuous oil pipe. Background Art

[0002] Continuous oil pipe is a pipe made of low-carbon alloy steel with good flexibility. It is also called flexible oil pipe. A roll of continuous oil pipe is several thousand meters long. During the laying process of oil continuous oil pipe, fixing devices are used to fix the pipeline.

[0003] The existing fixing device for oil coiled tubing is generally a pipe clamp, which fixes the oil coiled tubing between the upper clamp and the lower clamp by threaded cooperation of two sets of fastening bolts and nuts. However, in this installation method, when the upper clamp and the lower clamp need to be installed or removed, the two sets of fixing bolts and nuts need to be installed or removed in sequence, which is very cumbersome and inconvenient to quickly fix or detach the oil coiled tubing. Therefore, we propose a fixing assembly for oil coiled tubing to solve the above problems. Utility Model Content

Through the clamping adjustment mechanism, the movable plate can be adjusted to slide upward or downward in the two movable grooves.

[0009] Preferably, the two circular grooves on the bottom side of the movable plate are symmetrically arranged, and the circular plate is matched with the circular grooves, so that the connecting rod can drive the circular plate to rotate in the circular grooves.

[0010] Preferably, the number of the circular plate, the connecting rod, the upper clamping plate and the second rubber layer is two and they are symmetrically arranged.

[0011] Preferably, the inner wall of one side of the upper clamping plate is arranged in an arc-shaped structure, and the second rubber layer is adapted to the arc-shaped inner wall of one side of the upper clamping plate. When the second rubber layers of the inner walls of the two upper clamping plates are tightly against the coiled tubing body, the coiled tubing body can be stably clamped.

[0012] Compared with the prior art, the utility model has the following beneficial effects: the fixing assembly for the petroleum continuous tubing is configured to be rotatable. When the continuous tubing body is clamped and fixed, the two upper clamping plates are adjusted to rotate to the upper position of the continuous tubing body, and the two upper clamping plates are driven to move downward by the clamping adjustment mechanism to clamp and fix the continuous tubing body; when the continuous tubing body needs to be detached from the fixing device, the movable plate is adjusted to move upward by the clamping adjustment mechanism, so that the two upper clamping plates clamped and fixed on the continuous tubing body are in a relaxed state, which is convenient for adjusting the two upper clamping plates to move upward and also for realizing rotation adjustment, so that the continuous tubing body can be detached from the fixing device.

Through the clamping adjustment mechanism, the movable plate 6 can be adjusted to slide upward or downward in the two movable grooves 5; two circular grooves 10 are respectively provided on the bottom side of the movable plate 6, and a circular plate 11 is rotatably installed in the circular groove 10, and one end of a connecting rod 12 is fixedly installed on the top side of the circular plate 11, and the other end of the connecting rod 12 movably penetrates to the outside of the frame body 3 and is fixedly installed with an upper clamping plate 13, and the inner wall of the upper clamping plate 13 is provided with a second rubber layer 14, and the second rubber layer 14 is overlapped on the continuous oil pipe body 2.

[0020] Furthermore, the cross section of the frame body 3 is arranged in a U-shaped structure, and the top inner wall of the frame body 3 is arranged in an arc-shaped structure and is adapted to the coiled tubing body 2 .

[0021] Furthermore, the two circular grooves 10 on the bottom side of the movable plate 6 are symmetrically arranged, and the circular plate 11 is adapted to the circular groove 10 , so that the connecting rod 12 can drive the circular plate 11 to rotate in the circular groove 10 .

[0022] Furthermore, the number of the circular plate 11 , the connecting rod 12 , the upper clamping plate 13 and the second rubber layer 14 are all set to two, and they are symmetrically arranged.
