Description

Technical Field

[0001] This utility model relates to the field of petroleum equipment technology, and in particular to an adjustable oil pipe guide. Background Technology

[0002] The tubing drum is an important piece of equipment in coiled tubing drilling operations, mainly used for winding and releasing tubing during drilling. The guide is a device that orients and counts the tubing as it winds and releases on the tubing drum. When the tubing passes through the guide, the guide clamps the tubing and moves back and forth with the tubing drum system, orienting the tubing as it winds on the drum. At the same time, the counter inside the guide performs extended counting based on the winding and releasing of the tubing.

[0003] Existing tubing roller guides typically only accommodate tubing of a single specification. When changing to tubing of other specifications, the guide rollers of the guide must be replaced, which is cumbersome. In order to accommodate tubing of different specifications, the guide must be equipped with multiple mounting holes and multiple sets of guide rollers of different specifications and sizes. In some cases, the entire guide must be replaced, which is not very flexible and increases maintenance and manufacturing costs.

[0004] Therefore, it is necessary to propose an adjustable tubing guide to improve the guide's adaptability to tubing of different specifications. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing guides cannot be adapted to various specifications of oil pipes. An adjustable oil pipe guide is provided.

[0006] The technical solution of this utility model is:

[0007] An adjustable oil pipe guide includes an upper housing, a lower housing, and a counter assembly mounted on the upper housing. The upper housing is provided with an upper guide wheel assembly, and the lower housing is provided with a lower guide wheel assembly. The lower guide wheel assembly includes a ball screw pair, a flap plate, and a third connecting shaft fixed to the lower housing. The third connecting shaft is fitted with a bushing, and the end of the bushing is fixedly connected to one end of the flap plate. The other end of the flap plate is rotatably connected to a lower roller.

[0008] A push rod is fixedly connected to the bushing. The ball screw pair moves the push rod to rotate the flap, thereby moving the lower roller closer to or away from the upper guide wheel assembly.

[0009] Furthermore, the ball screw assembly includes a lead screw and a slider. One end of the lead screw is rotatably connected to the lower housing, and the other end of the lead screw is threadedly connected to the slider. The slider is slidably connected to the lower housing, and the rotation of the lead screw causes the slider to slide relative to the lower housing.

[0010] Furthermore, the counter assembly includes a counter housing and a counting device. The counter housing is rotatably connected to a counting wheel and an intermediate sprocket. The counting device is coaxially mounted with the intermediate sprocket. The counting wheel is coaxially fixed with a drive sprocket. The intermediate sprocket and the drive sprocket are driven by a chain.

[0011] Furthermore, one end of the counter housing is rotatably connected to the upper housing via a first connecting shaft, and the other end of the counter housing is movably connected to the upper housing via a spring. The distance between one end of the counter housing and the upper housing can be adjusted by the spring, thereby adjusting the distance the counting wheel penetrates into the upper housing.

[0012] Furthermore, the flap and the lower roller are rotatably connected via a fourth connecting shaft.

[0013] Furthermore, the lower and upper housings are secured by latches on both sides, and the lower housing is equipped with a dial, a scale, and a viewing window.

[0014] Furthermore, the upper guide wheel assembly includes an upper roller and a second connecting shaft.

[0015] Furthermore, a nut is provided at the end of the lead screw that is rotatably connected to the upper housing.

[0016] Furthermore, it also includes a guide connecting shaft, which is rotatably connected to the lower housing via a fifth connecting shaft.

[0017] Furthermore, there are at least two upper guide wheel sets arranged opposite to each other at both ends of the upper housing, and at least two lower guide wheel sets arranged opposite to each other at both ends of the lower housing.

[0018] This utility model discloses an adjustable oil pipe guide. The oil pipe passes between the upper and lower housings. A counter assembly counts the passing oil pipes. The upper guide wheel assembly is located above the oil pipe, and the lower guide wheel assembly is located below the oil pipe. When the distance between the upper guide wheel assembly and the lower roller does not match the diameter of the oil pipe due to different oil pipe sizes, rotating the ball screw pair can actuate the push rod, which in turn rotates the bushing. The rotation of the bushing drives the flap to rotate, and the rotation of the flap causes the lower roller located at the other end of the flap to rise or fall, thereby adjusting the distance between the lower roller and the upper guide wheel assembly. Compared with traditional technology, this technical solution can adapt to various oil pipes of different specifications, ensure the clamping force of the oil pipe, improve flexibility, and reduce maintenance and manufacturing costs.

Detailed Implementation

[0026] To make the technical means, technical features, utility model purpose and technical effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0027] Example 1:

[0028] like Figure 1 and Figure 2 As shown, this embodiment provides an adjustable oil pipe guide, including an upper housing 2, a lower housing 3, and a counter assembly 1 mounted on the upper housing 2. The upper housing 2 is provided with an upper guide wheel assembly, and the lower housing 3 is provided with a lower guide wheel assembly 34. The lower guide wheel assembly 34 includes a ball screw 35, a flap 361, and a third connecting shaft 38 fixed to the lower housing 3 with screws. Figure 4 The third connecting shaft 38 is provided with a bushing 363. The end of the bushing 363 is fixedly connected to one end of the flap 361 with screws. The other end of the flap 361 is rotatably connected to a lower roller 36 by a bearing. The bushing 363 is fixedly connected to a push rod 362. The ball screw 35 actuates the push rod 362 to rotate the flap 361, thereby causing the lower roller 36 to move closer to or away from the upper guide wheel assembly.

[0029] Preferred, such as Figure 3The ball screw 35 includes a lead screw and a slider 37. One end of the lead screw is rotatably connected to the lower housing 3 via a bearing, and the other end of the lead screw is connected to the slider 37 via a threaded drive. The slider 37 is slidably connected to the lower housing 3. The rotation of the lead screw causes the slider 37 to slide relative to the lower housing 3.

[0030] Preferred, such as Figure 2 The counter assembly 1 includes a counter housing 15 and a counting device 13. The counter housing 15 is rotatably connected to a counting wheel 16 and an intermediate sprocket 14 via bearings. The counting device 13 is coaxially mounted with the intermediate sprocket 14. A drive sprocket is coaxially fixed to the counting wheel 16. The intermediate sprocket 14 and the drive sprocket are driven by a chain. Preferably, one end of the counter housing 15 is rotatably connected to the upper housing 2 via a first connecting shaft 12 and bearings. The other end of the counter housing 15 is movably connected to the upper housing 2 via a spring 11. The distance between one end of the counter housing 15 and the upper housing 2 can be adjusted by extending and retracting the spring 11, thereby adjusting the distance the counting wheel 16 extends into the upper housing 2. Preferably, as shown in the example... Figure 4 The flap 361 and the lower roller 36 are rotatably connected by the fourth connecting shaft 39. Preferably, the lower housing 3 and the upper housing 2 are fixed by latches provided on both sides. The lower housing 3 is provided with a dial 31, a scale 33 and a viewing window 32. Preferably, the upper guide wheel group includes an upper roller 22 and a second connecting shaft 21. Preferably, the end of the lead screw that is rotatably connected to the upper housing 2 is provided with a nut 310. Preferably, it also includes a guide connecting shaft 4. The guide connecting shaft 4 and the lower housing 3 are rotatably connected by the fifth connecting shaft 41. Preferably, there are at least two upper guide wheel groups and they are arranged opposite to each other at both ends of the upper housing 2. There are at least two lower guide wheel groups 34 and they are arranged opposite to each other at both ends of the lower housing 3.

[0031] The counter assembly 1 of this invention is used to record the remaining length of the oil pipe on the drum. When the oil pipe passes through the guide, the counting wheel 16 will be close to the oil pipe. When the drum winds the oil pipe, it drives the counting wheel 16 to rotate forward, and the value on the counter increases, which corresponds to an increase in the length of the oil pipe on the drum. When the drum releases the oil pipe, it drives the counting wheel 16 to rotate in reverse, and the value on the counter decreases, which corresponds to a decrease in the length of the oil pipe on the drum.

[0032] The counting wheel 16 drives the counter to perform counting, which is an extended-range counting that can be increased or decreased. The rotation of the counting wheel 16 is transmitted to the intermediate wheel through a chain. Through a fixed ratio conversion, a direct proportional relationship is established between the counter value and the length of the oil pipe on the drum, and length statistics are implemented.

[0033] The upper housing 2 and the lower housing 3 are used together to clamp the oil pipe. The upper housing 2 and the lower housing 3 are connected by hinges and latches. By opening and closing the latches and moving the two around the hinges, the oil pipe can be taken out or put into the guide.

[0034] The counting wheel 16 is located between the two sets of guide wheels of the upper housing 2 and the two sets of guide wheels of the lower housing 3. The oil pipe is clamped by the two sets of guide wheels, keeping the oil pipe in a straight and stable state, making the counting wheel 16 more accurate.

[0035] The upper roller 22 and the lower roller 36 are V-groove structures, which can clamp oil pipes of different specifications and sizes.

[0036] By adjusting the lead screw 35, the lower roller 36 can be moved up and down, thereby changing the distance between it and the upper roller 22, so that the clamping space can be adapted to different specifications of oil pipes.

[0037] The lower guide wheel assembly 34 consists of two sets, left and right, each equipped with an adjusting screw 35. Turning the adjusting screw 35 moves the slider 37, which in turn pushes the flap 361 to rotate around the axis, thereby causing the lower roller 36 to rise and fall. This structure is an adjustable mechanism.

[0038] Each lead screw 35 operates independently without interfering with the others, effectively improving operability. Furthermore, their identical structure greatly enhances interchangeability and facilitates maintenance and replacement.

[0039] The slider 37 has a scale 33, and the corresponding lower housing 3 has a viewing window 32. The housing is equipped with a dial 31, which is marked with the positions of different specifications and models of oil pipes. The scale 33 can be adjusted to different positions to suit different oil pipes, making it convenient and quick to adjust.

[0040] The guide connecting shaft 4 is installed on the pipe laying system of the drum, driving the guide to move back and forth to achieve the orientation of the oil pipe winding on the drum.

[0041] Combination Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the working principle of the adjustable guide of the present invention is as follows: When the guide needs to clamp oil pipes of different specifications, unscrew the nut 310 at one end of the lead screw 35, and rotate the lead screw 35, as shown. Figure 5 and Figure 6 As shown, slider 37 slides outward (inward), pushing against push rod 362, forcing flap 361 to rotate around third connecting shaft 38, causing lower roller 36 to move upward (downward), shortening (increasing) the distance between lower roller 36 and upper roller 22, thus accommodating different oil pipe specifications. The scale 33 fixed to slider 37 also moves together, allowing the operator to... Figure 1 The visible window 32 is used to compare the position of the scale 33 on the dial 31 to determine the oil pipe specifications that the guide meets at this time. Then, tightening the nut 310 completes the adjustment of the guide specifications.

[0042] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. All equivalent changes and modifications made in accordance with the scope of the claims of this utility model should fall within the technical scope of this utility model.
