Description

Technical Field

[0001] This utility model relates to the field of pipeline dredging technology, specifically a pipeline dredging bend device. Background Technology

[0002] A pipeline is a device made up of pipes, pipe fittings, valves, etc., used to transport gases, liquids, or fluids containing solid particles.

[0003] Traditional municipal pipeline dredging equipment often results in debris getting stuck in the manholes, requiring manual entry, which is difficult, inefficient, and poses safety hazards, failing to meet the needs of urban development. Even if the pipe can be directly inserted into the manhole to flush the walls, the pipe is prone to bumping and rubbing against the manhole wall during insertion, affecting its lifespan. To address these issues, a pipeline dredging bend device is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a pipe cleaning and bending device that guides the coiled tubing from the vertical shaft into the horizontal shaft, reducing collisions and friction between the coiled tubing and the well, extending the service life of the coiled tubing, and completing the injection and recovery of the coiled tubing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pipe dredging bending device, including a fixed base, a side bending plate on the fixed base, a first bending plate rotatably mounted at the tail end of the side bending plate, a second bending plate rotatably mounted at the tail end of the first bending plate, a third bending plate rotatably mounted at the tail end of the second bending plate, and a fourth bending plate rotatably mounted at the tail end of the third bending plate. The first and second bending plates are connected by a telescopic component one, and the second and fourth bending plates are connected by a telescopic component two. Multiple pairs of rollers are rotatably mounted on the side bending plate, the first bending plate, the second bending plate, the third bending plate, and the fourth bending plate. During operation, a continuous tubing enters from the top of the bending device, and through angle adjustment of the several pairs of rollers, it transitions from a vertical entry to a horizontal exit.

[0006] Furthermore, adjacent bent plates 1, 2, 3, and 4 are rotatably connected by articulated pins. The articulated pins allow for more flexible connection angles between bent plates 1, 2, 3, and 4, which can be adjusted according to the actual working conditions.

[0007] Furthermore, multiple pairs of rollers are rotatably mounted on side bending plates, bending plate one, bending plate two, bending plate three, and bending plate four via roller pins. Each roller on the pipe bending device can rotate independently, reducing friction during continuous injection of oil tubing and extending the service life of the coiled oil tubing.

[0008] Furthermore, the telescopic component one is a hydraulic cylinder one, the fixed end of the hydraulic cylinder one is hinged to the bending plate one, and the output end of the hydraulic cylinder one is hinged to the bending plate two.

[0009] Furthermore, the second telescopic component is a hydraulic cylinder, with its fixed end hinged to the second bending plate and its output end hinged to the fourth bending plate. Through the extension and retraction of the first and second hydraulic cylinders, the bending device can be adjusted from 90° to 180°.

[0010] Furthermore, the rollers on the side bending plate are arranged in the opposite direction to those on bending plates one, two, three, and four. This reversal of their orientations ensures the coiled tubing is securely clamped within the bending device, improving its stability during operation.

[0011] Furthermore, the second and third bent plates, as well as the fourth bent plate, are connected by limiting plates. The limiting plates are used to limit the deflection angle between the second and third bent plates, and between the third and fourth bent plates.

[0012] Furthermore, the side bending plate is hinged to the fixed base, and the fixed base is connected to the bending plate via a telescopic member three. The telescopic member three enables the lateral deflection of the bending device, effectively meeting the operational requirements when the vertical and horizontal shafts are not on the same plane and lateral deflection is necessary.

[0013] Furthermore, the telescopic component three is a side-bending hydraulic cylinder. By extending and retracting the side-bending hydraulic cylinder, the lateral deflection of the pipe bending device can be achieved.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] 1. This pipe cleaning and bending device has a continuous oil pipe entering from the top of the bending device. Through the angle adjustment of several pairs of rollers, it can be changed from vertical entry to horizontal exit. During operation, the bending device can achieve an angle adjustment from 90° to 180° through the extension and retraction of oil cylinder one and oil cylinder two, which can be adjusted according to actual needs.

[0016] 2. This pipeline dredging bending device allows each roller to rotate independently, reducing friction during continuous injection of oil into the coiled tubing and extending its service life.

[0017] 3. This pipe dredging bending device uses the extension and retraction of the side bending cylinder to achieve lateral deflection of the bending device, which can meet the operational requirements when vertical and horizontal shafts are not on the same plane and lateral deflection is required.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-3 The pipe dredging bend device in this embodiment includes a fixed base 5, a side bend plate 7 on the fixed base 5, a bend plate 8 rotatably mounted at the tail end of the side bend plate 7, a bend plate 10 rotatably mounted at the tail end of the bend plate 10, a bend plate 3 rotatably mounted at the tail end of the bend plate 2 rotatably mounted at the tail end of the bend plate 3 rotatably mounted at the tail end of the bend plate 3 rotatably mounted at the tail end of the bend plate 4 rotatably mounted, the bend plate 18 and the bend plate 2 rotatably mounted at the tail end of the bend plate 3 rotatably mounted, the bend plate 10 and the bend plate 4 rotatably mounted at the tail end of the bend plate 7, the bend plate 18, the bend plate 2 rotatably mounted, the bend plate 3 rotatably mounted, and the bend plate 4 rotatably mounted on the side bend plate 7, the bend plate 18, the bend plate 2 rotatably mounted, the bend plate 3 rotatably mounted, and the bend plate 4 rotatably mounted on the bend plate 4.

[0024] During operation, the continuous tubing 3 enters from the top of the bending device and, through the angle adjustment of several pairs of rollers 2, changes from its original vertical entry to its horizontal exit.

[0025] Furthermore, the pipe bending device can achieve an angle adjustment from 90° to 180° by extending and retracting the first and second telescopic components.

[0026] In this embodiment, the first bent plate 8, the second bent plate 10, the third bent plate 12, and the fourth bent plate 14 are rotatably connected to each other by a joint pin 4.

[0027] The setting of the joint pin 4 makes the connection angle of the first bending plate 8, the second bending plate 10, the third bending plate 12 and the fourth bending plate 14 more flexible and can be adjusted according to the actual working scenario.

[0028] In this embodiment, multiple pairs of rollers 2 are rotatably mounted on the side bending plate 7, bending plate one 8, bending plate two 10, bending plate three 12 and bending plate four 14 respectively via roller pins 1.

[0029] Each roller 2 on the pipe bending device can rotate independently, reducing friction when the continuous oil pipe 3 is continuously injected and extending the service life of the continuous oil pipe.

[0030] In this embodiment, the first telescopic component is a hydraulic cylinder 9, the fixed end of which is hinged to the first bending plate 8, and the output end of which is hinged to the second bending plate 10. The second telescopic component is a hydraulic cylinder 13, the fixed end of which is hinged to the second bending plate 10, and the output end of which is hinged to the fourth bending plate 14.

[0031] By extending and retracting cylinders 9 and 13, the angle of the pipe bending device can be adjusted from 90° to 180°.

[0032] In this embodiment, the roller 2 on the side bending plate 7 is set in the opposite direction to the roller 2 on the bending plate 1, bending plate 2, bending plate 3, and bending plate 4.

[0033] The coiled tubing 3 first passes through the roller 2 on the side bending plate 7 from the top of the bending device, and then passes through the roller 2 on the first bending plate 8, the second bending plate 10, the third bending plate 12 and the fourth bending plate 14 in sequence. By reversing the orientation of the rollers, the coiled tubing 3 can be securely clamped in the bending device, which improves the stability of the coiled tubing 3 during operation.

[0034] In this embodiment, the second bending plate 10 and the third bending plate 12, as well as the third bending plate 12 and the fourth bending plate 14, are connected by a limiting plate 11.

[0035] The limiting plate 11 can be used to limit the deflection angle between the second bending plate 10 and the third bending plate 12, as well as between the third bending plate 12 and the fourth bending plate 14.

[0036] Among them, the second bent plate 10 and the third bent plate 12 are rotatably mounted on a limiting plate 11, and the limiting plate 11 has an arc-shaped hole. The third bent plate 12 is fixed with a limiting rod located in the arc-shaped hole. Similarly, the limiting method between the third bent plate 12 and the fourth bent plate 14 can be obtained. By setting the arc-shaped hole and the limiting rod, the limiting plate 11 can be used to limit the offset angle between adjacent bent plates.

[0037] In this embodiment, the side bending plate 7 is hinged to the fixed base 5, and the fixed base 5 and the bending plate 8 are connected by the telescopic member 3.

[0038] The lateral deflection of the pipe bending device is achieved by the extension and retraction of the telescopic component three, which can meet the operational requirements of the vertical shaft and the horizontal shaft not being on the same plane and requiring lateral deflection.

[0039] Furthermore, the telescopic component three is a side-bending cylinder 6. The fixed end of the side-bending cylinder 6 is hinged to the fixed base 5, and the output end of the side-bending cylinder 6 is hinged to the bending plate 8. By extending and retracting the side-bending cylinder 6, the lateral deflection of the pipe bending device can be realized.

[0040] In summary, according to the above embodiments, during actual operation, the pipe bending device is first sent into the vertical shaft. Based on the position of the horizontal shaft, the pipe bending device bends, accurately guiding the continuous tubing 3 horizontally into the horizontal shaft. The continuous tubing 3 then flushes the pipe wall. Because the continuous tubing 3 has a certain degree of rigidity, it will not be blocked by debris in the well, and the debris can be flushed to the next wellhead. The entire pipeline dredging work can be completed without personnel entering the well. After the operation is completed, the pipe bending device is extended to a vertical position by the extension and retraction of the hydraulic cylinder and pulled out from the wellhead.
