Description

Technical Field

[0001] This utility model relates to the field of oil drilling pipe cleaning, and in particular to an oil pipe feeding and turning device. Background Technology

[0002] In the mid-to-late stages of oilfield development, especially with the shift from waterflooding to polymer flooding, the problems of wax and scale buildup in oil wells become very serious. Scale buildup in pipelines narrows flow channels, increases pressure loss, reduces pipeline efficiency, and can even cause safety hazards such as tubing blockage and pump jamming.

[0003] Tubing cleaning is an important step in well workover operations. The quality and efficiency of the cleaning operation are crucial prerequisites for the smooth implementation of subsequent tubing flaw detection and repair operations. This plays an important role in ensuring the safety of oil well production and improving economic efficiency.

[0004] Traditional oil pipe cleaning mainly relies on manual labor, which is time-consuming and labor-intensive. Some automated cleaning equipment is primarily a single-station structure, requiring the oil pipes to be hoisted to the cleaning station during cleaning, and then moved away after cleaning, followed by the hoisting of replacement pipes. This not only makes loading cumbersome, but also necessitates frequent pipe replenishment due to the lack of a buffer platform. The hoisting process consumes a significant amount of cycle time, impacting overall cleaning efficiency. Utility Model Content

[0005] This invention provides an oil pipe feeding and turning device, which solves the problem of the lack of a feeding buffer station in a single-station oil pipe cleaning device, requiring frequent material replenishment.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an oil pipe feeding and turning device, including a feeding mechanism, the feeding mechanism including one or more support frames, the support frame is provided with a feeding section and a ramp connected to each other, the lower end of the ramp is provided with a stop plate, the end of the feeding section away from the ramp is provided with a limiting stop, the support frame is also provided with a rotatable turning plate below the stop plate, and a connecting frame is provided on one side of the support frame. The turning plate rotates to turn the oil pipe onto the connecting frame.

[0007] In a preferred embodiment, the support frame has multiple spaced-apart flip-up plates along its length, multiple bearing seats, and a rotatable transmission rod. The transmission rod is rotatably connected to each bearing seat. The transmission rod has multiple spaced-apart drive rods along its length, and the end of each drive rod has a hinged connecting rod that is hinged to the flip-up plate.

[0008] In the preferred embodiment, a linear push cylinder is provided on the support frame, and the two ends of the linear push cylinder are respectively hinged to the support frame and the drive rod.

[0009] In the preferred embodiment, the transmission rod is a polygonal shaft.

[0010] In the preferred embodiment, one end of the flip-up lever protrudes from the stop plate towards the inner side of the support frame, and the protruding length of the flip-up lever is less than the diameter of the oil pipe but greater than the radius of the oil pipe.

[0019] like Figure 1-4 In a certain context, an oil pipe loading and turning device includes a loading mechanism 1, which includes one or more support frames 101. The support frame 101 is provided with a loading section 102 and a ramp 103 connected to each other. A stop plate 104 is provided at the lower end of the ramp 103. A limiting stop 106 is provided at the end of the loading section 102 away from the ramp 103. A rotatable turning plate 105 is also provided below the stop plate 104 on the support frame 101. A connecting frame 2 is provided on one side of the support frame 101. The turning plate 105 rotates to turn the oil pipe 3 onto the connecting frame 2.

[0020] The feeding mechanism 1 may include multiple split-type support frames 101, and the number of support frames 101 can be freely adjusted according to the length of the oil pipes 3. Each support frame 101 must be adjusted in front and behind to move it until each stop plate 104 is on the same plane.

[0021] The oil pipe 3 is placed at the feeding section 102 by clamping both ends with a crane or mechanical arm. The feeding section 102 also has a slight inclination. The oil pipe 3 rolls to the slope 103 and accumulates. Multiple oil pipes 3 can be buffered on the support frame 101 at the same time.

[0022] The cleaning equipment is located on one side of the connecting frame 2, and the cleaning pipe is inserted into the interior of 3 for automated cleaning.

[0023] In a preferred embodiment, the support frame 101 is provided with a plurality of spaced-apart flip plates 105 along its length, the support frame 101 is also provided with a plurality of bearing seats 110, and a rotatable transmission rod 111 is provided. The transmission rod 111 is rotatably sleeved with each bearing seat 110. The transmission rod 111 is provided with a plurality of spaced-apart drive rods 108 along its length, and the end of the drive rod 108 is provided with a hinged connecting rod 107, which is hinged to the flip plate 105.

[0024] In a preferred embodiment, the support frame 101 is provided with a linear push cylinder 109, and the two ends of the linear push cylinder 109 are respectively hinged to the support frame 101 and the drive rod 108.

[0025] The end of the drive rod 108 is fixedly sleeved on the transmission rod 111. The linear push cylinder 109 is a hydraulic cylinder, a pneumatic cylinder or an electric cylinder. The lower end of the cylinder body is hinged to the reinforcing cross link of the lower layer of the support frame 101 through a hinge seat, and the upper end of the cylinder body is hinged to the middle of the drive rod 108 through a hinge seat.

[0026] One or more linear push cylinders 109 can be equipped on the support frame 101. The number of linear push cylinders 109 can be less than the number of tilting plates 105, saving costs. One or more linear push cylinders 109 push the middle of the drive rod 108. The transmission rod 111 transmits the force to the other drive rods 108, simultaneously lifting the inner end of the tilting plate 105. The tilting plate 105 tilts and lifts the oil pipe 3. When the inner end of the tilting plate 105 is higher than the outer end, the oil pipe 3 rolls down into the V-shaped frame on the connecting frame 2.

[0027] In the preferred embodiment, the transmission rod 111 is a polygonal shaft.

[0028] The bearing housing 110 has an inner ring with an adapter sleeve, the inner side of which has a polygonal structure that matches the transmission rod 111. Similarly, the drive rod 108 also has a polygonal hole that fits into the transmission rod 111. This polygonal fit prevents slippage and facilitates transmission.

[0029] In the preferred embodiment, one end of the flip plate 105 protrudes from the stop plate 104 on the side closer to the support frame 101. The protruding length of the flip plate 105 is less than the diameter of the oil pipe 3 and greater than the radius of the oil pipe 3.

[0030] The length of the protrusion is less than the diameter of oil pipe 3, which ensures that only one oil pipe 3 will be lifted up in a single flip.

[0031] The length of the protrusion is greater than the radius of the oil pipe 3 to ensure that the lifting point is the lowest point of the oil pipe 3, thus avoiding the situation where the oil pipe 3 is pushed back.

[0032] In a preferred embodiment, the support frame 101 includes a bottom frame 112 and an upper frame 113. Multiple columns 114 are provided between the bottom frame 112 and the upper frame 113. Multiple middle beams 115 are provided along the length of the support frame 101. Each middle beam 115 is connected to the column 114, and each bearing seat 110 is provided on the middle beam 115.

[0033] The support frame 101 is a welded frame. The upper frame 113 is provided with a longitudinal beam at certain intervals. One section of the longitudinal beam is straight and is called the feeding section 102, and the other section is inclined and is called the ramp section 103.

[0034] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
