Description

Technical Field

[0001] This invention relates to the field of injection head equipment technology, and in particular to a limiting structure for a weight sensor and a continuous tubing system. Background Technology

[0002] Coiled tubing workover rigs are widely used in oil and gas field workover, drilling, completion, and logging operations, playing an increasingly important role in oil and gas field exploration and development. Coiled tubing workover rigs are hailed as "all-purpose" equipment. The coiled tubing injection head is the power unit for running and pulling coiled tubing into and out of the well, and is a key component of the coiled tubing workover rig. The weight sensor is the core component of the coiled tubing injection head, used to detect the load on the coiled tubing to allow for real-time adjustment of relevant parameters.

[0003] When the coiled tubing injection head device is in operation, the main housing of the coiled tubing injection head device must be pressed against the base. However, when the coiled tubing injection head device is in transport, the main housing must be separated from the base to avoid damage to the weight sensor due to vibration or impact. Therefore, it is essential to provide a limiting structure for the weight sensor to facilitate the pressing or separation of the main housing and the base. Summary of the Invention

[0004] This invention provides a limiting structure for a weight sensor and a continuous tubing device to enable the main housing and base to be quickly pressed together or separated.

[0005] This invention provides a limiting structure for a weight sensor, comprising: a first limiting member for connecting to the main housing of a coiled tubing unit; a weight sensor sleeved on the outside of the first limiting member and fixedly mounted on a base; an adjusting member sleeved on the first end of the first limiting member, the adjusting member being movable along the axial direction of the first limiting member, such that the second ends of the adjusting member and the first limiting member respectively abut against the two sides of the weight sensor, or that the second ends of the adjusting member and the first limiting member respectively separate from the two sides of the weight sensor; and a support plate fixedly mounted on the base and located at the first end of the first limiting member, the support plate being detached from or abutting against the adjusting member during the movement of the adjusting member.

[0006] According to the limiting structure of a weight sensor provided by the present invention, under the action of the adjusting member, the first limiting member can move along its axial direction, and the moving direction of the first limiting member is opposite to the moving direction of the adjusting member.

[0007] According to the present invention, a limiting structure for a finger weight sensor further includes a sleeve, which is sleeved outside the first limiting member and located between the finger weight sensor and the adjusting member. Under the action of the adjusting member, the sleeve can abut against or separate from the finger weight sensor.

[0008] According to the present invention, a limiting structure for a weight sensor further includes: a second limiting member, the second limiting member being threadedly connected to a first end of the first limiting member, and the support plate being located between the sleeve and the second limiting member.

[0009] According to the present invention, a limiting structure for a finger weight sensor further includes a connecting sleeve, which is sleeved on the outside of the first limiting member and located between the finger weight sensor and the second end of the first limiting member. During the movement of the first limiting member, the connecting sleeve can abut against or separate from the second end of the first limiting member.

[0010] According to the limiting structure of a finger weight sensor provided by the present invention, a fastener is further included, the fastener passing through the finger weight sensor and fixing the finger weight sensor to the base.

[0011] According to the present invention, a limiting structure for a finger weight sensor includes a connecting sleeve comprising: a first connecting portion and a second connecting portion, wherein the inner diameters of the first connecting portion and the second connecting portion are equal, the outer diameter of the first connecting portion is greater than the outer diameter of the second connecting portion, the bottom surface of the first connecting portion abuts against the top surface of the finger weight sensor, and the second connecting portion is sleeved between the first limiting member and the finger weight sensor.

[0012] According to the present invention, a limiting structure for a weight sensor is provided, wherein the adjusting member is threadedly connected to the first limiting member, and the adjusting member is a nut or a ratchet.

[0013] The present invention also provides a coiled tubing device, comprising: a main housing; a base; and a limiting structure for the weight sensor as described above, the limiting structure being connected to the main housing and the base.

[0014] According to the present invention, a coiled tubing device further includes a load-bearing component connected to the main housing. The load-bearing component is sleeved outside the first limiting component and is located between the connecting sleeve and the second end of the first limiting component. Under the action of the adjusting component, the second end of the first limiting component can abut against or separate from the load-bearing component.

[0015] The limiting structure of the weight sensor provided by this invention, by setting a first limiting member and an adjusting member, allows the second end of the first limiting member and the adjusting member to abut against both sides of the weight sensor, or to separate the second end of the first limiting member and the adjusting member from both sides of the weight sensor, during the process of the adjusting member moving along the axial direction of the first limiting member. This enables the main housing and base of the coiled tubing equipment to abut or separate quickly, improving work efficiency and reducing the labor intensity of operators.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0023] The terms "first" and "second" in the specification and claims of this invention may explicitly or implicitly include one or more of those features. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0024] The following is combined with Figures 1 to 3 The present invention describes the limiting structure of the weight sensor and the coiled tubing equipment.

[0025] like Figure 1 As shown, in one embodiment of the present invention, the limiting structure of the weight sensor includes: a first limiting member 10, a weight sensor 20, an adjusting member 30, and a support plate 40. The first limiting member 10 is used to connect to the main housing 101 of the coiled tubing equipment. The weight sensor 20 is sleeved on the outside of the first limiting member 10 and fixedly mounted on the base 102. The adjusting member 30 is sleeved on the first end of the first limiting member 10. The adjusting member 30 can move axially along the first limiting member 10, so that the second ends of the adjusting member 30 and the first limiting member 10 respectively abut against the two sides of the weight sensor 20, or so that the second ends of the adjusting member 30 and the first limiting member 10 respectively separate from the two sides of the weight sensor 20. The support plate 40 is fixedly mounted on the base 102 and located at the first end of the first limiting member 10. During the movement of the adjusting member 30, the support plate 40 can separate from or abut against the adjusting member 30.

[0026] Specifically, the coiled tubing equipment includes a main housing 101 and a base 102. One end of the main housing 101 is hinged to one end of the base 102, and the other end of the main housing 101 is separate from the other end of the base 102. In this embodiment, a limiting structure is disposed between the main housing 101 and the base 102. During coiled tubing operation, the limiting structure causes the main housing 101 and the base 102 to abut against each other; when the coiled tubing equipment is in transport mode, the limiting structure causes the main housing 101 and the base 102 to separate.

[0027] Specifically, the first end of the first limiting member 10 is connected to the support plate 40, and the support plate 40 is fixed to the base 102. When the coiled tubing is in operation, the adjusting member 30 moves in the direction close to the weight sensor 20, so that the second ends of the adjusting member 30 and the first limiting member 10 respectively abut against the two sides of the weight sensor 20, thereby pressing the main housing 101 against the base 102. The line connecting the hinge point of the main housing 101 and the base 102 and the weight sensor 20 can be regarded as a lever. When the coiled tubing is lowered or raised, it will generate a downward or upward force on the lever. The load of the coiled tubing during operation can be detected by the weight sensor 20, and the operating parameters of the coiled tubing equipment can be adjusted according to the load.

[0028] When the coiled tubing equipment is in transport, to prevent the main housing 101 from squeezing the weight sensor 20 due to vibration during transport, the adjusting member 30 can be adjusted to separate the adjusting member 30 from the weight sensor 20. Simultaneously, the second end of the first limiting member 10 also separates from the weight sensor 20. Specifically, when the adjusting member 30 moves away from the weight sensor 20, the adjusting member 30 separates from the weight sensor 20, and the weight sensor 20 separates from the second end of the first limiting member 10. This creates a certain gap between the weight sensor 20 and the main housing 101, allowing space for the main housing 101 to sway and preventing the main housing 101 from contacting and impacting the weight sensor 20, thus avoiding damage to the weight sensor 20.

[0029] Optionally, in an embodiment of the present invention, the adjusting member 30 may be threadedly connected to the first limiting member 10. When the adjusting member 30 is rotated, it may move axially along the first limiting member 10. When the adjusting member 30 is rotated toward the weight sensor 20, it abuts against the weight sensor 20. Continuing to rotate the adjusting member 30 causes the first limiting member 10 to move toward the weight sensor 20, thereby causing the second end of the first limiting member 10 to abut against the weight sensor 20, and thus causing the main housing 101 to abut against the base 102. When the adjusting member 30 is rotated away from the weight sensor 20, it separates from the weight sensor 20. When the adjusting member 30 contacts the support plate 40, rotating the adjusting member 30 causes the first limiting member 10 to move away from the weight sensor 20, thereby causing the second end of the first limiting member 10 to separate from the weight sensor 20, and thus achieving the separation of the main housing 101 from the base 102.

[0030] Optionally, in an embodiment of the present invention, a snap-fit ​​structure may be provided between the adjusting member 30 and the first limiting member 10. When the adjusting member 30 abuts against the weight sensor 20, and the weight sensor 20 abuts against the second end of the first limiting member 10, the snap-fit ​​structure can lock the adjusting member 30 and the first limiting member 10, thereby achieving the abutment between the main housing 101 and the base 102. When it is necessary to separate the main housing 101 from the base 102, the adjusting member 30 and the first limiting member 10 are unlocked, and the adjusting member 30 moves away from the weight sensor 20, contacting the support plate 40. At this time, the first limiting member 10 is rotated, causing the first limiting member 10 to move away from the weight sensor 20, thereby separating the first end of the first limiting member 10 from the weight sensor 20.

[0031] The limiting structure of the weight sensor provided in this embodiment of the invention, by setting a first limiting member and an adjusting member, allows the second end of the first limiting member and the adjusting member to abut against both sides of the weight sensor, or to separate the second end of the first limiting member and the adjusting member from both sides of the weight sensor, during the process of the adjusting member moving along the axial direction of the first limiting member. This enables the main housing and base of the coiled tubing equipment to abut or separate, achieving rapid abutment or separation of the main housing and base, improving work efficiency, and reducing the labor intensity of operators.

[0032] Furthermore, in one embodiment of the present invention, under the action of the adjusting member 30, the first limiting member 10 can move along its axial direction, and the moving direction of the first limiting member 10 is opposite to the moving direction of the adjusting member 30.

[0033] Specifically, when the adjusting member 30 moves in the direction close to the finger weight sensor 20, and when the adjusting member 30 abuts against the finger weight sensor 20, continuing to rotate the adjusting member 30 will cause the second end of the first limiting member 10 to move in the direction close to the finger weight sensor 20, thereby causing the second end of the first limiting member 10 to abut against the finger weight sensor 20. Correspondingly, when the adjusting member 30 moves in the direction away from the finger weight sensor 20, and when the adjusting member 30 abuts against the support plate 40, continuing to rotate the adjusting member 30 will cause the first limiting member 10 to move in the direction away from the finger weight sensor 20, thereby causing the second end of the first limiting member 10 to separate from the finger weight sensor 20.

[0034] Furthermore, in one embodiment of the present invention, the adjusting member 30 is threadedly connected to the first limiting member 10. Specifically, the first limiting member 10 is provided with external threads, the adjusting member 30 can be a rotatable component such as a nut or ratchet, and the adjusting member 30 is provided with internal threads. When the adjusting member 30 is rotated, the adjusting member 30 can move along the axial direction of the first limiting member 10.

[0035] like Figure 2 As shown, in one embodiment of the present invention, the limiting structure of the finger weight sensor further includes a sleeve 50. The sleeve 50 is sleeved on the outside of the first limiting member 10 and is located between the finger weight sensor 20 and the adjusting member 30. Under the action of the adjusting member 30, the sleeve 50 can abut against or separate from the finger weight sensor 20.

[0036] Specifically, the sleeve 50 is located between the weight sensor 20 and the adjusting member 30. When the adjusting member 30 moves towards the weight sensor 20, it pushes the sleeve 50 closer to the weight sensor 20, causing the sleeve 50 to abut against the weight sensor 20. Continuing to rotate the adjusting member 30 causes the first limiting member 10 to move towards the weight sensor 20, with its second end abutting against the weight sensor 20, thus abutting the main housing 101 against the base 102. When the adjusting member 30 moves in the opposite direction, the sleeve 50 moves downwards under gravity, separating from the weight sensor 20. When the adjusting member 30 contacts the support plate 40, rotating the adjusting member 30 causes the first limiting member 10 to move away from the weight sensor 20, thus separating its second end from the weight sensor 20, thus separating the main housing 101 from the base 102.

[0037] like Figure 1 and Figure 2 As shown, in one embodiment of the present invention, the limiting structure of the weight sensor further includes a second limiting member 90. The second limiting member 90 is threadedly connected to the first end of the first limiting member 10, and the support plate 40 is located between the sleeve 50 and the second limiting member 90.

[0038] Specifically, when the adjusting member 30 moves away from the finger weight sensor 20, and when the adjusting member 30 contacts the support plate 40, the adjusting member 30 cannot continue to move towards the first end of the first limiting member 10. At this time, if the adjusting member 30 is rotated, the adjusting member 30 can drive the first limiting member 10 to move away from the finger weight sensor 20, thereby separating the second end of the first limiting member 10 from the finger weight sensor 20.

[0039] Furthermore, in this embodiment, the second limiting member 90 is threadedly connected to the second end of the first limiting member 10. When the first limiting member 10 moves in a direction away from the weight sensor 20, its maximum displacement is limited to ensure that the first limiting member 10 is still connected to the second limiting member 90. This allows the second limiting member 90 to limit the stroke of the first limiting member 10, preventing the first limiting member 10 from moving too much under the drive of the adjusting member 30, which would cause the gap between the main housing 101 and the base 102 to become too large.

[0040] like Figure 2 As shown, in one embodiment of the present invention, the limiting structure of the finger weight sensor further includes a connecting sleeve 60. The connecting sleeve 60 is sleeved on the outside of the first limiting member 10, and the connecting sleeve 60 is located between the finger weight sensor 20 and the second end of the first limiting member 10. During the movement of the first limiting member 10, the connecting sleeve 60 can abut against or separate from the second end of the first limiting member 10.

[0041] Specifically, as the adjusting member 30 moves towards the weight sensor 20, it pushes the sleeve 50 upward, bringing it into contact with the weight sensor 20. Once in contact, the adjusting member 30 continues to rotate, causing the first limiting member 10 to move towards the weight sensor 20, bringing its second end into contact with the connecting sleeve 60, thus securing the main housing 101 against the base 102. Conversely, as the adjusting member 30 moves away from the weight sensor 20, the sleeve 50 separates from the weight sensor 20. After contacting the support plate 40, the adjusting member 30 continues to rotate, causing the first limiting member 10 to move away from the weight sensor 20, separating its second end from the connecting sleeve 60, thus separating the main housing 101 from the base 102.

[0042] Furthermore, such as Figure 3 As shown, in an embodiment of the present invention, the connecting sleeve 60 includes: a first connecting part 61 and a second connecting part 62. The inner diameters of the first connecting part 61 and the second connecting part 62 are equal, the outer diameter of the first connecting part 61 is greater than the outer diameter of the second connecting part 62, the bottom surface of the first connecting part 61 abuts against the top surface of the finger weight sensor 20, and the second connecting part 62 is sleeved between the first limiting member 10 and the finger weight sensor 20.

[0043] Specifically, the first connecting part 61 and the second connecting part 62 form a T-shaped structure, and the finger weight sensor 20 is engaged with the T-shaped structure to position the finger weight sensor 20.

[0044] Furthermore, in an embodiment of the present invention, the limiting structure of the finger weight sensor further includes a fastener 70, which passes through the finger weight sensor 20 and fixes the finger weight sensor 20 to the base 102. Optionally, the fastener 70 can be a bolt.

[0045] This invention also provides a continuous tubing device, including: a main housing 101, a base 102, and a limiting structure for a weight sensor.

[0046] Specifically, the limiting structure of the weight sensor includes: a first limiting member 10, a weight sensor 20, an adjusting member 30, and a support plate 40. The first limiting member 10 is connected to the main housing 101, and the first end of the first limiting member 10 is connected to the support plate 40. The support plate 40 is fixed to the base 102, and the weight sensor 20 is connected to the base 102.

[0047] When the adjusting member 30 moves in a direction close to the weight sensor 20, the adjusting member 30 abuts against the weight sensor 20, and the second end of the first limiting member 10 abuts against the weight sensor 20, thereby abutting the main body 101 against the base 102. When the adjusting member 30 moves in a direction away from the weight sensor 20, the adjusting member 30 separates from the weight sensor 20, and the second end of the first limiting member 10 separates from the weight sensor 20, thereby separating the main body 101 from the base 102.

[0048] The coiled tubing equipment provided in this embodiment of the invention, by setting a limiting structure of a weight sensor, allows the main housing and the base to abut against each other during coiled tubing operation. When the coiled tubing equipment is in transport mode, the main housing and the base separate, realizing the rapid abutment or separation of the main housing and the base, improving work efficiency and reducing the labor intensity of operators.

[0049] like Figure 2 As shown, in an embodiment of the present invention, the coiled tubing equipment further includes a load-bearing component 80. The load-bearing component 80 is connected to the main housing 101 and is sleeved around the outside of the first limiting component 10. The load-bearing component 80 is located between the connecting sleeve 60 and the second end of the first limiting component 10. Under the action of the adjusting component 30, the second end of the first limiting component 10 can abut against or separate from the load-bearing component 80.

[0050] Specifically, in this embodiment, the load-bearing member 80 and the first limiting member 10 are connected by threads. When the adjusting member 30 moves in a direction closer to the weight sensor 20, the adjusting member 30 pushes the sleeve 50 to move, causing the sleeve 50 to abut against the weight sensor 20. Continuing to rotate the adjusting member 30 causes the first limiting member 10 to move in a direction closer to the weight sensor 20, thereby causing the second end of the first limiting member 10 to abut against the load-bearing member 80, and thus causing the main housing 101 to abut against the base 102. When the adjusting member 30 moves in a direction away from the weight sensor 20, the adjusting member 30 contacts the support plate 40, and the sleeve 50 separates from the weight sensor 20. Continuing to rotate the adjusting member 30 causes the first limiting member 10 to move in a direction away from the weight sensor 20, causing the second end of the first limiting member 10 to separate from the load-bearing member 80, and thus causing the main housing 101 to separate from the base 102.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
