DETAILED DESCRIPTION

[0039] It should be noted that the embodiments and technical features in the present application can be combined with each other without conflict, and the detailed description in the specific embodiments should be understood as an explanation and description of the purpose of the present application, and should not be regarded as an improper limitation on the present application.

[0040] In the description of the embodiments of the present application, it should be noted that the directions or position relationships indicated by the terms "height direction", "top", "bottom", "side", "first direction", "second direction" and the like are based on the directions or position relationships shown in the drawings. These direction terms are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the embodiments of the present application. The present application will be further described in detail below in combination with the drawings and specific embodiments.

[0041] The injection head is a device for providing sufficient thrust and pull force to run in and out coiled tubing in coiled tubing operation, and for injecting liquid. The injection head tower can lift the injection head to the required height from the ground to improve the construction efficiency and ensure the construction safety. In the related art, in order to improve the working range of the injection head, a moving device is usually arranged at the top of the tower to drive the movement of the injection head. However, the arrangement of the moving device at the top of the tower makes the center of gravity of the injection head tower too high, causing the problem of instability of the injection head tower.

[0042] The injection head tower 100 provided in the present application, please refer to Figures 1 to 4 , the injection head tower 100 comprises a base frame 1, a moving device 2 and a support frame 3. The moving device 2 is arranged on the base frame 1. The support frame 3 is arranged on the moving device 2 and can move relative to the base frame 1 through the moving device 2. The moving device 2 comprises a first base 21 and a first driving device 23. The first base 21 is arranged on the base frame 1 and defines an installation space 22 with the base frame 1. The first driving device 23 comprises a first driving member 231. The first driving member 231 is arranged in the installation space 22, and the first driving member 231 is used to drive the first base 21 to move in a first direction, wherein the first direction intersects with the height direction of the injection head tower 100.

[0043] The base frame 1 is arranged at the bottom of the injection head tower 100 and is used to provide support for the injection head tower 100. The base frame 1 should have a certain self-weight and a large floor area, so that the overall center of gravity of the injection head tower 100 is lowered, and the projection area of the base frame 1 on the plane perpendicular to the height direction is larger than the projection area of the support frame 3. In this way, the base frame 1 can provide stable support for the injection head tower 100 and reduce the possibility of rollover of the injection head tower 100.

[0044] The base frame 1 usually adopts a frame structure, and the base frame 1 is a structure formed by welding steel beams. The steel beams have good mechanical strength and a certain self-weight, can provide support for the injection head tower 100, and the large self-weight can also lower the overall center of gravity of the injection head tower 100. When the weight of the upper part of the injection head tower 100 is too heavy, the base frame 1 can also be increased in weight to lower the overall center of gravity of the injection head tower 100 and improve the stability of the injection head tower 100.

[0045] For example, the base frame 1 is a rectangular frame structure formed by welding a plurality of steel beams, and support legs are arranged at the four corners of the rectangular frame structure to support the base frame 1. The support legs have a leveling function to ensure that the working area of the injection head tower 100 remains horizontal under different ground conditions. The structure for realizing the leveling function of the support legs is not limited here, for example, it can be a hydraulic leveling leg, which is simple to operate. It can also be a screw leveling leg, which has a simple structure and high reliability.

[0046] The support frame 3 is a structure for fixing the injection head of the injection head tower 100, and should have a certain rigidity to prevent deformation when supporting the injection head, thereby ensuring the safety of the injection head tower 100. On the premise of ensuring the design strength, the support frame 3 should be designed as light as possible to reduce the weight of the upper part of the injection head tower 100, thereby reducing the center of gravity of the injection head tower 100 and improving the stability of the injection head tower 100.

[0047] The moving device 2 is arranged on the chassis 1 and drives the movement of the support frame 3. One side of the moving device 2 is connected with the chassis 1, and the other side is connected with the support frame 3, thereby connecting the support frame 3 with the chassis 1. The support frame 3 moves relative to the chassis 1 through the moving device 2, thereby driving the movement of the injection head arranged above the support frame 3. The specific structure of the moving device 2 is not limited here.

[0048] The first base 21 is a structure that can move relative to the moving device 2, and the specific structure is not limited here. One side of the first base 21 is connected with the first driving device 23, and the other side is connected with the support frame 3, thereby driving the movement of the support frame 3.

[0049] The installation space 22 is the space between the first base 21 and the chassis 1. On the one hand, since the first base 21 and the chassis 1 need to move relative to each other, there is a certain gap between the first base 21 and the chassis 1 to ensure that the first base 21 and the chassis 1 do not interfere with each other during movement. In addition, a movement structure such as a sliding block and sliding rail structure needs to be installed between the first base 21 and the chassis 1 to ensure smooth movement between the two. Therefore, enough space needs to be reserved between the first base 21 and the chassis 1 for the installation of the movement structure. On the other hand, in order to realize the automation of the injection head tower 100, a driving device needs to be arranged to drive the relative movement of the first base 21 and the chassis 1. Therefore, when designing, the space between the first base 21 and the chassis 1 can be fully utilized. While considering the installation of the movement structure, the installation of the driving device is also taken into account. The space is appropriately enlarged to ensure the installation of the first base 21 and the first driving device 23. In this way, the installation space 22 can be saved, and the overall size can be reduced.

[0050] Here, it should be noted that the installation space 22 is the area between the chassis 1 and the first base 21. The specific position of the installation space 22 is not limited here, as long as it can install the first driving device 23 between the chassis 1 and the first base 21, and ensure that the first driving device 23 can normally drive the movement of the first base.

[0051] The specific structure of the first driving member 231 is not limited here, and the first base 21 can be driven to move, for example, can be a cylinder structure, a hydraulic cylinder structure, a linear motor structure, or a screw sliding block driving structure, etc. By setting the first driving member 231, the first base 21 is driven to move, and by controlling the movement of the first driving member 231, the automation control of the moving device 2 is realized.

[0052] The first direction, the height direction, is for convenience of description, and is Figures 1 to 4 The direction shown in the figure.

[0053] The injection head tower 100 provided in the present application is provided with the first base 21 which moves relative to the chassis 1 in the first direction, so that the support frame 3 connected with the moving device 2 can move relative to the chassis 1, thereby driving the movement of the injection head on the support frame 3. The moving device 2 is arranged on the lower chassis 1, which has a simple structure, reduces the overall gravity center of the injection head tower 100, and improves the stability of the movement of the support frame 3. On the other hand, the gap between the chassis 1 and the first base 21 is utilized to form the installation space 22 to install the first driving device 23, which is conducive to reducing the external volume of the injection head tower 100.

[0054] In some embodiments, referring to Figures 1 to 4 The first driving device 23 includes a first sliding assembly 232, the first sliding assembly 232 is arranged in the installation space 22, and the first base 21 is slidably arranged on the chassis 1 through the first sliding assembly 232.

[0055] The first sliding assembly 232 is a movement structure arranged between the first base 21 and the chassis 1, one end of the first sliding assembly 232 is connected with the chassis 1, and the other end is connected with the first base 21. The first base 21 and the chassis 1 are slidably connected through the first sliding assembly 232, so as to realize the relative movement of the first base 21 and the chassis 1. At the same time, the setting of the first sliding assembly 232 also reduces the friction resistance of the relative movement between the first base 21 and the chassis 1, so as to facilitate the driving of the first driving member 231.

[0056] The specific structure of the first sliding assembly 232 is not limited here, for example, can be a pulley structure, or a sliding block and sliding rail structure, etc.

[0057] The first sliding assembly 232 is arranged in the installation space 22, and it should be noted that the first sliding assembly 232 needs to slide in the first direction, so that the first base 21 can move relative to the chassis 1 in the first direction.

[0058] By setting the first sliding assembly 232 in the installation space 22, the first sliding assembly 232 drives the first base 21 to be slidably arranged on the chassis 1, so that the frictional resistance between the first base 21 and the chassis 1 is reduced, the driving efficiency of the first driving member 231 is improved, and the smoothness of the movement of the first base 21 is improved.

[0059] In some embodiments, referring to Figures 2 to 4 In the plane perpendicular to the height direction, the center line of the first sliding assembly 232 is collinear with the center line of the first driving member 231.

[0060] Generally, the optimal force direction of the first sliding assembly 232 is the movement direction, when the force is not along the movement direction, on the one hand, the force cannot be completely used for driving. On the other hand, when the first sliding assembly 232 is subjected to a force in a non-movement direction, the force in the non-movement direction not only does not drive the first sliding assembly 232, but also increases the sliding resistance of the first sliding assembly 232, causing the movement wear of the first sliding assembly 232. Excessive force in the non-movement direction can even cause the sliding fit of the first sliding assembly 232 to fail.

[0061] The center line of the first sliding assembly 232 is collinear with the center line of the first driving member 231, that is, the movement direction of the first sliding assembly 232 is collinear with the driving direction of the first driving member 231 in the plane perpendicular to the height direction, the driving force action line of the first driving member 231 and the movement direction line of the first sliding assembly 232 have no angle, so that most of the driving force of the first driving member 231 is used to drive the sliding of the first sliding assembly 232, even if the driving force action line of the first driving member 231 and the movement direction line of the first sliding assembly 232 do not coincide, the moment of the driving force acting on the first sliding assembly 232 also offsets the pressure of the first base 21 mounted on the first sliding block 2321 assembly, without lateral moment, guaranteeing the optimal sliding state of the first sliding assembly 232.

[0062] In some embodiments, the first sliding assembly 232 is a sliding block guide rail structure, and the first driving member 231 is a hydraulic oil cylinder structure. The sliding block guide rail structure and the hydraulic oil cylinder structure are both arranged in the installation space 22 and are both arranged along the first direction. The center line of the sliding block guide rail structure is the center line of the sliding block in the sliding block guide rail structure, and the center line of the hydraulic oil cylinder structure is the center line of the piston rod in the hydraulic oil cylinder structure. The center line of the sliding block and the center line of the piston rod are collinear in the plane perpendicular to the height direction, so that the piston rod can only push the sliding block to move along the first direction, and the sliding block is not forced in the lateral direction, and is in the optimal interaction state.

[0063] By projecting in the plane perpendicular to the height direction, the first sliding assembly 232 is collinear with the center line of the first driving member 231, so that the driving force of the first driving member 231 can be transmitted to the first sliding assembly 232 with maximum efficiency, improving the driving efficiency of the first driving member 231 and reducing the sliding wear of the first sliding assembly 232.

[0064] In some embodiments, referring to Figures 2 to 4 , the mobile device 2 comprises a second base 24 and a second driving device 25. The second base 24 is arranged on the first base 21. The second driving device 25 comprises a second driving member 251 for driving the second base 24 to move in a second direction, wherein the height direction of the injection head tower 100, the second direction and the first direction intersect.

[0065] The second base 24 is arranged on the first base 21 and can move relative to the first base 21. The specific structure of the second base 24 is not limited here. One side of the second base 24 is connected with the first base 21, and the other side is connected with the support frame 3, so that the support frame 3 can be driven to move in the second direction. Since the second base 24 is arranged on the first base 21, the first base 21 can drive the second base 24 connected thereto to move in the first direction, so that the support frame 3 arranged on the second base 24 can move in the first direction in addition to the second direction. Through the combined movement of the first direction and the second direction, the support frame 3 can move freely in the plane.

[0066] The specific structure of the second driving member 251 is not limited here, and it can drive the second base 24 to move, for example, it can be a cylinder structure, a hydraulic cylinder structure, a linear motor structure or a screw slide driving structure, etc. By arranging the second driving member 251 to drive the first base 21 to move, the movement of the first driving member 231 is controlled to realize the automatic control of the mobile device 2.

[0067] The second direction is the direction shown in Figure 2 , Figure 4 for the convenience of description.

[0068] By arranging the second base 24 to move in the second direction relative to the first base 21, the support frame 3 arranged on the second base 24 can move in the first direction as well as in the second direction. Through the combined movement of the first direction and the second direction, the support frame 3 can move freely in the plane, and the structure is simple.

[0069] In some embodiments, referring to Figures 2 to 4The second driving device 25 comprises a second sliding assembly 252 arranged between the first base 21 and the second base 24, and the second base 24 is slidably arranged on the first base 21 through the second sliding assembly 252.

[0070] The second sliding assembly 252 is a movement structure arranged between the second base 24 and the chassis 1. One end of the second sliding assembly 252 is connected with the chassis 1, and the other end is connected with the second base 24. The second base 24 and the chassis 1 are slidably connected through the second sliding assembly 252, so as to realize the relative movement between the second base 24 and the chassis 1. At the same time, the second sliding assembly 252 reduces the frictional resistance between the second base 24 and the chassis 1, so as to facilitate the driving of the second driving member 251.

[0071] The specific structure of the second sliding assembly 252 is not limited here, which can be a pulley structure, a sliding block guide rail structure, or the like.

[0072] By arranging the second sliding assembly 252, the second base 24 is slidably arranged on the first base 21 through the second sliding assembly 252, so as to reduce the frictional resistance between the second base 24 and the first base 21, and facilitate the driving efficiency of the second driving member 251 and the smoothness of the movement of the second base 24.

[0073] In some embodiments, referring to Figures 2 to 4 The second driving member 251 is arranged on the side surface of the second base 24.

[0074] Here, the side surface of the second base 24 refers to the position where the second driving member 251 is arranged. In the plane perpendicular to the height direction, the projection of the second driving member 251 and the second base 24 does not overlap, and only the second sliding assembly 252 is arranged between the second base 24 and the first base 21 in the height direction. Therefore, the distance between the second base 24 and the first base 21 can be as small as possible, so as to reduce the height of the moving device 2, facilitate the arrangement of the support frame 3, and also facilitate the reduction of the overall gravity center of the injection head tower 100.

[0075] It should be noted that the specific position of the second driving member 251 arranged on the side surface of the second base 24 is not limited here. Generally, in order to reduce the side torque of the driving force of the second driving member 251 on the second sliding assembly 252, the second driving member 251 should be as close as possible to the second sliding assembly 252 from the side surface.

[0076] In some embodiments, referring to Figures 2 to 4The first sliding assembly 232 comprises a first sliding block 2321 and a first sliding rail 2322, the first sliding block 2321 and the first sliding rail 2322 are slidingly fitted along the first direction, and one of the first sliding block 2321 and the first sliding rail 2322 is connected with the base frame 1, and the other is connected with the first base 21.

[0077] The first sliding block 2321 and the first sliding rail 2322 are slidingly fitted along the first direction, so that the base frame 1 and the first base 21 connected with the first sliding block 2321 and the first sliding rail 2322 respectively can be slidingly fitted along the first direction. The first sliding block 2321 can be connected with the base frame 1, and the first sliding rail 2322 is connected with the first base 21. Alternatively, the first sliding block 2321 can be connected with the first base 21, and the first sliding rail 2322 is connected with the base frame 1.

[0078] By arranging the first sliding block 2321 and the first sliding rail 2322, one of the first sliding block 2321 and the first sliding rail 2322 is connected with the base frame 1, and the other is connected with the first base 21, so that the base frame 1 and the first base 21 can be slidingly fitted along the first direction. The structure is simple, the sliding resistance of the first sliding block 2321 and the first sliding rail 2322 is small, and the driving efficiency is improved.

[0079] In some embodiments, please refer to Figures 2 to 4 The second sliding assembly 252 comprises a second sliding block 2521 and a second sliding rail 2522, the second sliding block 2521 and the second sliding rail 2522 are slidingly fitted along the second direction, and one of the second sliding block 2521 and the second sliding rail 2522 is connected with the first base 21, and the other is connected with the second base 24.

[0080] The second sliding block 2521 and the second sliding rail 2522 are slidingly fitted along the second direction, so that the first base 21 and the second base 24 connected with the second sliding block 2521 and the second sliding rail 2522 respectively can be slidingly fitted along the second direction. The second sliding block 2521 can be connected with the first base 21, and the second sliding rail 2522 is connected with the second base 24. Alternatively, the second sliding block 2521 can be connected with the second base 24, and the second sliding rail 2522 is connected with the first base 21.

[0081] By arranging the second sliding block 2521 and the second sliding rail 2522, one of the second sliding block 2521 and the second sliding rail 2522 is connected with the first base 21, and the other is connected with the second base 24, so that the first base 21 and the second base 24 can be slidingly fitted along the second direction. The structure is simple, the sliding resistance of the second sliding block 2521 and the second sliding rail 2522 is small, and the driving efficiency is improved.

[0082] In some embodiments, please refer to Figures 2 to 4The first base 21 comprises two first longitudinal beams 211 and two first transverse beams 212, the two first transverse beams 212 are arranged at intervals along the second direction, and two ends of the two first longitudinal beams 211 are respectively connected to two ends of the two first transverse beams 212 along the first direction. The first base 21 is arranged opposite to the chassis 1, and the first transverse beam 212 and the chassis 1 define a mounting space 22, and the first sliding rail 2322 is connected with the first transverse beam 212 or the chassis 1.

[0083] Here, the first transverse beam 212 is a beam parallel to the first direction, and the first longitudinal beam 211 is a beam parallel to the second direction. The distance between the two first transverse beams 212 arranged at intervals along the second direction, that is, the size of the first longitudinal beam 211, determines the size of the first base 21 in the second direction, and the size of the first transverse beam 212 itself determines the size of the first base 21 in the first direction.
