Description

Technical Field

[0001] This utility model relates to the technical field of drilling injection head equipment. More specifically, this utility model relates to a gooseneck tube load monitoring device. Background Technology

[0002] The gooseneck tube is a device used in coiled tubing operations. It is installed on top of the injection head and used in conjunction with the injection head. The coiled tubing is placed in the gooseneck tube guide groove, which guides and delivers the coiled tubing on the tubing reel to the injection head. Existing gooseneck tubes mostly employ a hinged front and rear arc-shaped frame as their main structure. The front arc-shaped frame faces the tubing reel, while the rear arc-shaped frame is closer to the injection head frame. The gooseneck tube is unfolded or folded by using hydraulic cylinders to extend and retract within these two arc-shaped frames. When unfolded, it serves as the working support and guide structure for the coiled tubing. Some gooseneck tube structures have support frames primarily located inside the rear arc-shaped frame. The coiled tubing rests within the gooseneck tube guide groove, applying the tubing's own weight and the operational back tension load to the gooseneck tube itself. If the back tension is not properly adjusted during operation, excessive load can damage the gooseneck tube, potentially causing it to collapse. Therefore, monitoring the load status of the gooseneck tube is necessary. Currently, effective monitoring methods exist for this type of problem, and existing gooseneck tube structures require further design optimization to better position monitoring points and improve structural safety. Summary of the Invention

[0003] The purpose of this invention is to provide a gooseneck tube load monitoring device to solve the technical problem of the lack of effective and safe monitoring of gooseneck tube load in the prior art.

[0004] To achieve these objectives and other advantages according to this utility model, a gooseneck tube load monitoring device is provided, comprising a first bracket and a second bracket. The two ends of the first bracket are respectively connected to the inner ends of the rear arc-shaped frame of the gooseneck tube. The lower end of the second bracket is connected to the middle of the front side of the injection head frame and is inclined upward toward the front arc-shaped frame of the gooseneck tube. A hydraulic cylinder is mounted on the second bracket. The bottom of the hydraulic cylinder has a hinge hole and is hinged to the middle of the second bracket by a connecting seat. The top of the telescopic end of the hydraulic cylinder is slidably connected to the inner side of the front arc-shaped frame near the rear arc-shaped frame. The connecting seat includes a fixing plate. The bottom of the fixing plate is fixed to the middle of the second bracket. A pair of positioning blocks are connected upward to each other on the top of the fixing plate. A pin hole is opened through the middle of the positioning block. A pin-type load sensor is inserted and connected between the pair of pin holes and the hinge hole. The pin-type load sensor is used to measure the shear force at the hinge.

[0005] Preferably, the second bracket is a trapezoidal frame structure, including an upper crossbar, a lower crossbar, and a pair of opposing diagonal bars. The upper crossbar is connected between the upper ends of the pair of diagonal bars, and a circular hole is provided in the middle of the upper crossbar for fitting onto the upper end of the cylinder body of the hydraulic cylinder. The lower crossbar is fixed between the lower ends of the pair of diagonal bars, and the fixing plate of the connecting seat is connected to the middle of the lower crossbar.

[0006] Preferably, a bottom crossbar is connected to the pair of diagonal bars directly below the lower crossbar, and a reinforcing member is connected between the middle of the bottom crossbar and the middle of the lower crossbar.

[0007] Preferably, the pin-type load sensor has two annular grooves, and the positioning block extends radially inward at the end of the pin hole away from the hinge hole to form a limiting ring. In the axial direction of the pin hole, the position of the limiting ring matches the outer diameter of the pin-type load sensor near the annular groove, so as to axially limit the pin-type load sensor.

[0008] Preferably, the pin-type load sensor also has a slightly curved slot, and a retaining plate is provided on the outer side of one end of the positioning block away from the hinge hole, corresponding to the position of the slot. The lower end of the retaining plate is used to embed downward into the slot to restrict the rotation of the slot. External bolt holes are symmetrically provided on the upper end of the retaining plate, and internal bolt holes are provided on the side of the positioning block facing the retaining plate, corresponding to the external bolt holes. The retaining plate is fastened by screwing bolts into the corresponding internal bolt holes and external bolt holes together.

[0009] Preferably, an alarm is also provided, which is communicatively connected to the pin-type load sensor. The pin-type load sensor is used to issue an alarm signal when the load is overloaded, and the alarm is used to sound an alarm after receiving the alarm signal.

[0010] This utility model has at least the following beneficial effects: The gooseneck tube load monitoring device of this utility model includes a first bracket and a second bracket. The first bracket is used to support and reinforce the rear arc frame, and the second bracket is used to support the front arc frame. A hydraulic cylinder is hinged between the second bracket and the front arc frame. The extension and retraction of the hydraulic cylinder realizes the folding or unfolding of the front arc frame relative to the rear arc frame in the vertical plane. At the same time, a connecting seat is formed at the hinge of the hydraulic cylinder and the second bracket using a fixing plate and positioning block structure. A pin-type load sensor is arranged on the connecting seat at the hinge along the direction perpendicular to the vertical plane of the gooseneck tube, replacing the connecting pin on the existing gooseneck tube bracket. During operation, the load is transmitted downward through the pin-type load sensor, and the load on the gooseneck tube is monitored through the pin-type load sensor. When the working load exceeds the safety value, an early warning is issued to ensure operational safety.

[0014] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

Therefore, they should not be construed as limitations on this utility model.

[0016] like Figure 1-3As shown, the gooseneck tube load monitoring device of this utility model includes a first support 3 and a second support 4. The two ends of the first support 3 are respectively connected to the inner ends of the rear arc-shaped frame 1 of the gooseneck tube. The lower end of the second support 4 is connected to the middle of the front side of the injection head frame and is inclined upward toward the front arc-shaped frame 2 of the gooseneck tube. A hydraulic cylinder 5 is provided on the second support 4. The bottom of the cylinder body of the hydraulic cylinder 5 has a hinge hole 10 and is hinged to the middle of the second support 4 through a connecting seat 6. The top of the telescopic end of the hydraulic cylinder 5 is slidably connected to the inner side of the front arc-shaped frame 2 near the rear arc-shaped frame 1. The connecting seat 6 includes a fixing plate 7. The bottom of the fixing plate 7 is fixed to the middle of the second support 4. A pair of positioning blocks 8 are connected upward to the top of the fixing plate 7. A pin hole 9 is opened through the middle of the positioning block 8. A pin-type load sensor 11 is inserted and connected between the pair of pin holes 9 and the hinge hole 10. The pin-type load sensor 11 is used to measure the shear force at the hinge.

[0017] The existing gooseneck pipe's two-section arc-shaped frame structure is designed separately. A first support 3 and a second support 4 are respectively installed for the front arc-shaped frame 2 and the rear arc-shaped frame 1. The rear arc-shaped frame 1 does not fold relative to the derrick; it mainly relies on the rotation of the front arc-shaped frame 2 around the hinge point to achieve the change between folded and unfolded states. The first support 3 can adopt existing connection positions and methods, mainly forming a chord connection with the rear arc-shaped frame 1 for support and reinforcement. The second support 4 itself is set at a relative vertical inclination after the derrick is unfolded, close to the core area of ​​the front arc-shaped frame 2 that is subjected to the force of the tubing. The second support 4 serves as a limiting support point for the front arc-shaped frame 2 in the folded state. Simultaneously, a hydraulic cylinder 5 is hinged to the second support 4, and the hydraulic cylinder 5 is then slidably connected to the inner side of the front arc-shaped frame 2. The inner side of the front arc-shaped frame 2 can be equipped with a chord to strengthen the structural rigidity. A groove is formed at the bottom of the chord along its length, with the groove only limited in width. The top of the telescopic end of the hydraulic cylinder 5 is slidably connected to the groove of the chord. The extension and retraction of the hydraulic cylinder 5 enables the unfolding or folding of the front arc-shaped frame 2. The hydraulic cylinder 5 is directly related to the state of the front arc-shaped frame 2. The positioning block 8 is connected to the fixing plate 7. The bottom of the hydraulic cylinder 5 is inserted into the gap between a pair of positioning blocks 8. At the hinge point between the hydraulic cylinder 5 and the second bracket 4, i.e., between the pin hole 9 and the hinge hole 10, a pin-type load sensor 11 is coaxially installed perpendicular to the hinge direction of the hydraulic cylinder 5 to monitor the change in load force at this location. If the load exceeds a preset value, it indicates a structural safety risk, and adjustments or work should be made promptly. The pin-type load sensor 11 can be a Zhike Limin GH-9 pin sensor. Specific installation and usage methods can be found in the corresponding product manual and will not be elaborated here.

[0018] The gooseneck tube load monitoring device of this utility model includes a first support 3 and a second support 4. The first support 3 is used to support and reinforce the rear arc frame 1, and the second support 4 is used to support the front arc frame 2. A hydraulic cylinder 5 is hinged between the second support 4 and the front arc frame 2. The extension and retraction of the hydraulic cylinder 5 realizes the folding or unfolding of the front arc frame 2 relative to the rear arc frame 1 in the vertical plane. At the same time, a connecting seat 6 is formed at the hinge of the hydraulic cylinder 5 and the second support 4 using a fixing plate 7 and a positioning block 8. A pin-type load sensor 11 is arranged on the connecting seat 6 at the hinge in a direction perpendicular to the vertical plane of the gooseneck tube, replacing the connecting pin on the existing gooseneck tube support. During operation, the load is transmitted downward through the pin-type load sensor 11, and the load on the gooseneck tube is monitored through the pin-type load sensor 11, which helps to ensure the structural safety of the gooseneck tube during operation and allows for timely safety measures to be taken.

[0019] In another technical solution, such as Figure 1-3 As shown, the second bracket 4 is a trapezoidal frame structure, including an upper crossbar 12, a lower crossbar 13, and a pair of opposing diagonal bars 14. The upper crossbar 12 is connected between the upper ends of the pair of diagonal bars 14. A circular hole is opened in the middle of the upper crossbar 12 for fitting onto the upper end of the cylinder body of the hydraulic cylinder 5. The lower crossbar 13 is fixed between the lower ends of the pair of diagonal bars 14. The fixing plate 7 of the connecting seat 6 is connected to the middle of the lower crossbar 13.

[0020] The second support 4 is a trapezoidal frame structure consisting of two diagonal bars 14, an upper horizontal bar 12, and a lower horizontal bar 13. The upper end reduces space occupation and is smaller in size than the lower end. The middle of the lower horizontal bar 13 is fixed with a connecting seat 6, and the middle of the upper horizontal bar 12 is provided with a round hole to guide and support the lower and upper ends of the hydraulic cylinder 5 respectively, thereby improving the structural support safety.

[0021] In another technical solution, such as Figure 1-3 As shown, a pair of diagonal bars 14 are connected to a bottom crossbar 15 directly below the lower crossbar 13. A reinforcing member 16 is connected between the middle of the bottom crossbar 15 and the middle of the lower crossbar 13 to further improve the support capacity for the bottom of the hydraulic cylinder 5.

[0022] In another technical solution, such as Figure 1-3 As shown, the pin-type load sensor 11 has two annular grooves. The positioning block 8 extends radially inward at the end of the pin hole 9 away from the hinge hole 10 to form a limiting ring 17. In the axial direction of the pin hole 9, the position of the limiting ring 17 matches the outer diameter of the pin-type load sensor 11 near the annular groove, so as to axially limit the pin-type load sensor 11.

[0023] Based on the existing structure of the pin-type load sensor 11, a mounting groove is generally provided at the annular groove for attaching structures such as double-shear resistance strain gauges. These mounting grooves are located at the neutral axis of the hollow cross-section, where the shear stress is the greatest, enabling accurate capture of stress deformation signals. Corresponding to the existing structure of the pin-type load sensor 11, a positioning block 8 is provided. The diameter of the hinge hole 10 matches and slides with the outer diameter of the middle part of the pin-type load sensor 11. The diameter of the pin hole 9 at the position where the limiting ring 17 is not formed is slightly larger than the diameter of the corresponding position on the pin-type load sensor 11. The position of the limiting ring 17 matches the outer diameter of the pin-type load sensor 11 near the annular groove, thereby limiting the pin-type load sensor 11 axially and avoiding interference with the sensor's detection of shear force in the vertical axis.

[0024] In another technical solution, such as Figure 1-3 As shown, the pin-type load sensor 11 also has a slightly curved slot 18. A retaining plate 19 is provided on the outer side of one end of the positioning block 8, away from the hinge hole 10, corresponding to the slot 18. The lower end of the retaining plate 19 is used to embed downwards into the slot 18 to restrict the rotation of the slot 18. Symmetrical outer bolt holes 20 are provided on the upper end of the retaining plate 19. An inner bolt hole 20 is provided on the side of the positioning block 8 facing the retaining plate 19 corresponding to the outer bolt holes 20. The retaining plate 19 is secured by screwing bolts 20 into both the corresponding inner and outer bolt holes 20. A pair of outer bolt holes 20 and a pair of inner bolt holes 20 can be provided in the front-back direction. The positioning block 8 can also be configured as a detachable two-part structure to facilitate the installation of the pin-type load sensor 11, secured together by bolts 20, and further strengthened by the retaining plate 19.

[0025] In another technical solution, such as Figure 1-3 As shown, an alarm is also provided, which is communicatively connected to the pin-type load sensor 11. The pin-type load sensor 11 is used to issue an alarm signal when the load is overloaded, and the alarm is used to sound an alarm upon receiving the alarm signal. The communication method of the pin-type load sensor 11 is described in the product manual. Its alarm logic is a simple basic function and can be connected to a remote terminal computer, mobile phone, or display screen. The functional principle is generally not described in detail here. Alternatively, a load sensor with integrated alarm function can be selected.

[0026] In summary, the gooseneck tube load monitoring device of this utility model includes a first support 3 and a second support 4. The first support 3 is used to support and reinforce the rear arc frame 1, and the second support 4 is used to support the front arc frame 2. A hydraulic cylinder 5 is hinged between the second support 4 and the front arc frame 2. The extension and retraction of the hydraulic cylinder 5 realizes the folding or unfolding of the front arc frame 2 relative to the rear arc frame 1 in the vertical plane. At the same time, a connecting seat 6 is formed at the hinge of the hydraulic cylinder 5 and the second support 4 using a fixing plate 7 and a positioning block 8. A pin-type load sensor 11 is arranged on the connecting seat 6 at the hinge in a direction perpendicular to the vertical plane of the gooseneck tube, replacing the connecting pin on the existing gooseneck tube support. During operation, the load is transmitted downward through the pin-type load sensor 11, and the load on the gooseneck tube is monitored through the pin-type load sensor 11. When the operating load exceeds the safety value, an early warning is issued to ensure operational safety.
