[0032] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0033] In the description of the embodiments of the present application, it should be noted that the terms "center," "upper," "lower," "horizontal," "top," "bottom," "inner," "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the embodiments of the present application and to simplify the description. They do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be construed as limiting the embodiments of the present application. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0034] In the description of the embodiments of this application, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of this application based on the specific circumstances.

[0035] The injection head tower generally includes a base frame and a multi-layer skid frame, at least part of which is usually raised and lowered by a telescopic mechanism. During the oil production process, the injection head is usually installed in the skid frame on the top layer of the injection head tower. Under the guidance of the injection head, components such as the blowout preventer connected to the injection head can pass through the injection head tower and be introduced into the oil well.

[0036] In the related art, sliders and slide rails are arranged between the telescopic skids to provide guidance during the lifting process, but the sliders are disassembled and assembled in a direction perpendicular to the mating surface. There is usually no space between the outer skid and the inner skid to disassemble and assemble the sliders. The skid needs to be disassembled before the sliders can be replaced, resulting in low efficiency in the installation and maintenance of the sliders.

[0037] Based on the above situation, the first aspect of the embodiment of the present application provides a skid assembly 10, see Figures 1 to 6 . The pry frame assembly 10 includes a pry frame unit 11 and a slider unit 12. The pry frame unit 11 includes a first pry frame 111 and a second pry frame 112. At least a portion of the second pry frame 112 is sleeved in the first pry frame 111 and can reciprocate relative to the first pry frame 111 along the height direction of the pry frame assembly 10. The slider unit 12 is detachably arranged on the first pry frame 111 or the second pry frame 112 along the first direction. The slider unit 12 has a mating surface 122a. The first pry frame 111 and the second pry frame 112 can be slidably matched along the height direction of the pry frame assembly 10 at least through the mating surface 122a. The first direction intersects with the height direction and is parallel to the mating surface 122a.

[0038] It should be noted that the skid assembly 10 is a multi-layer skid that can be raised and lowered by a telescopic mechanism. Specifically, the number of skid units 11 can be two, three, four, five, six, seven or eight, etc., without limitation.

[0039] The number of the slider units 12 can be one, two, three, four, five, six, seven, eight, nine or ten, etc., which is not limited here.

[0040] It should be noted that, when the skid unit 11 includes a plurality of skids, the first skid 111 and the second skid 112 are any two adjacent skids among the plurality of skids.

[0041] At least a portion of the second pry frame 112 is sleeved within the first pry frame 111 and can reciprocate relative to the first pry frame 111 along the height direction of the pry frame assembly 10. That is, the pry frame assembly 10 has a retracted state and an expanded state. In the retracted state, at least a portion of the second pry frame 112 is sleeved within the first pry frame 111. In the expanded state, at least a portion of the second pry frame 112 can extend out of the first pry frame 111 along the height direction. The pry frame assembly 10 can switch between the retracted state and the expanded state, thereby achieving reciprocating movement of the second pry frame 112 relative to the first pry frame 111 along the height direction of the pry frame assembly 10.

[0042] The slider unit 12 is detachably arranged on the first skid frame 111 or the second skid frame 112 along the first direction. The detachable arrangement of the slider unit 12 is convenient for replacing the slider unit 12, thereby being more convenient for assembling the skid frame assembly 10 and improving maintenance efficiency.

[0043] It should be noted that the slider unit 12 is arranged on the first pry frame 111 or the second pry frame 112. Correspondingly, the second pry frame 112 or the first pry frame 111 cooperates with the slider unit 12. In this way, the slider unit 12 can guide the second pry frame 112 along the height direction in a direction perpendicular to the mating surface 122a, thereby improving the stability and reliability of the sliding cooperation between the second pry frame 112 and the first pry frame 111 along the height direction of the pry frame assembly 10.

[0044] For example, multiple slider units 12 are provided on the first pry frame 111. A single slider unit 12 can limit the position of the second pry frame 112 within the first pry frame 111 in a direction perpendicular to the mating surface 122a. This allows each slider unit 12 to collectively limit the position of the second pry frame 112 within the first pry frame 111 in different directions, thereby guiding the second pry frame 112 in the height direction. This allows the first pry frame 111 and the second pry frame 112 to slide together along the height direction of the pry frame assembly 10. Furthermore, the slider units 12 can reduce scratches that easily occur between the first pry frame 111 and the second pry frame 112 due to hard contact, thereby reducing maintenance frequency.

[0045] It should be noted that the first pry frame 111 and the second pry frame 112 can at least slide together along the height direction of the pry frame assembly 10 through the mating surface 122a. That is, there is no space between the first pry frame 111 and the second pry frame 112 in the direction perpendicular to the mating surface 122a for disassembling and assembling the slider unit 12.

[0046] Exemplarily, the slider unit 12 is detachably disposed on the first pry frame 111 along the first direction, and the mating surface 122 a of the slider unit 12 faces the interior of the first pry frame 111 .

[0047] Exemplarily, the slider unit 12 is detachably disposed on the second pry frame 112 along the first direction, and the mating surface 122 a of the slider unit 12 faces the outside of the second pry frame 112 .

[0048] Exemplarily, the mating surface 122 a is parallel to the height direction of the pry assembly 10 .

[0049] It should be noted that the slider unit 12 is detachably arranged on the first pry frame 111 or the second pry frame 112 along the first direction, wherein the first direction intersects with the height direction and is parallel to the mating surface 122a, which means that the first direction is the side of the mating surface 122a. The slider unit 12 can be installed on the first pry frame 111 or the second pry frame 112 from the side of the mating surface 122a, and the slider unit 12 can be removed from the side, so that the working space for disassembly and assembly of the slider unit 12 is on the side of the mating surface 122a. The slider unit 12 can be disassembled and assembled without splitting the first pry frame 111 and the second pry frame 112, which improves the situation where there is no space for disassembly and assembly of the slider unit 12 in the direction perpendicular to the mating surface 122a between the first pry frame 111 and the second pry frame 112, making the installation and disassembly of the slider unit 12 more convenient and improving the efficiency of installing and replacing the slider unit 12.

[0050] The assembly and disassembly direction of the slider unit 12 , that is, the first direction, may intersect with or be perpendicular to the height direction.

[0051] Exemplarily, the first direction is perpendicular to the height direction, that is, the slider unit 12 can be horizontally installed on the first pry frame 111 or the second pry frame 112 from the side of the mating surface 122a, and the slider unit 12 can be horizontally removed from the side of the mating surface 122a.

[0052] The skid assembly 10 provided in the embodiment of the present application comprises a slider unit 12 detachably mounted on the first skid 111 or the second skid 112 along a first direction. Accordingly, the slider unit 12 is mated with the second skid 112 or the first skid 111. This allows the slider unit 12 to guide the second skid 112 in the height direction perpendicular to the mating surface 122a, thereby improving the stability and reliability of the sliding engagement between the second skid 112 and the first skid 111 along the height direction of the skid assembly 10. Furthermore, the slider unit 12 can be disassembled and assembled along the first direction, that is, from the side of the mating surface 122a, without separating the first skid 111 and the second skid 112. This alleviates the problem of lack of space between the first skid 111 and the second skid 112 in the direction perpendicular to the mating surface 122a for disassembling the slider unit 12. This makes installation and removal of the slider unit 12 more convenient, improving the efficiency of installation and replacement of the slider unit 12.

[0053] For some examples, see Figures 1 to 6 The slider unit 12 is detachably mounted on the first skid frame 111 along a first direction. The slider unit 12 is slidably engaged with the column 1121 of the second skid frame via the engaging surface 122a.

[0054] It should be noted that the column 1121 of the second skid frame can extend along the height direction of the skid frame assembly 10, so that the slider unit 12 can slide and cooperate with the column along the height direction of the skid frame assembly 10 as much as possible, thereby realizing the lifting and lowering of the second skid frame 112.

[0055] Specifically, the slider unit 12 is disposed on the first skid frame 111 located on the outside, and the slider unit 12 is matched with the outer facade of the column 1121 of the second skid frame.

[0056] Exemplarily, the slider unit 12 is disposed on the second skid frame 112 located on the inner side, and the slider unit 12 cooperates with the inner vertical surface of the column 1113 of the first skid frame.

[0057] It should be noted that the mating surface 122a of the slider unit 12 is the surface on the slider unit 12 that is used to contact and mate with the inner surface of the column 1113 of the first skid frame or the outer surface of the column 1121 of the second skid frame.

[0058] The slider unit 12 provided on the first skid 111 directly cooperates with the column 1121 of the second skid, eliminating the slide rail structure on the skid that cooperates with the slider unit 12, making the structure of the skid unit 11 simpler and reducing the difficulty of processing.

[0059] Here, the slider unit 12 is detachably mounted on the first pry frame 111 along a first direction. Accordingly, the slider unit 12 is mated with the column 1121 of the second pry frame. Thus, the slider unit 12 directly mates with the column, eliminating the need for a slide rail and simplifying the structure of the pry frame unit 11. Furthermore, the slider unit 12 can limit the column in a direction perpendicular to the mating surface 122a, thereby guiding the second pry frame 112 in the height direction.

[0060] For some examples, see Figures 1 to 6 The first pry frame 111 is provided with a receiving groove 111a. The slider unit 12 includes a fixing member 121 and a slider 122. The slider 122 is provided with a mating surface 122a. The slider 122 is inserted into the receiving groove 111a along the first direction and is fixed to the first pry frame 111 by the fixing member 121.

[0061] It should be noted that the first pry frame 111 is provided with a receiving groove 111a, the slider 122 is inserted into the receiving groove 111a along the first direction, and the slider 122 is fixed to the first pry frame 111 through the fixing member 121. That is, at this time, the slider 122 is installed on the first pry frame 111 along the first direction.

[0062] The receiving groove 111 a provided on the first pry frame 111 may be located on the inner side of the first pry frame 111 close to the second pry frame 112 .

[0063] It should be noted that the number of the accommodating grooves 111 a may be equal to the number of the slider units 12 .

[0064] The slider unit 12 includes a fixing member 121 and a slider 122 , wherein the fixing member 121 may be a sheet metal member, and the slider 122 may be made of nylon.

[0065] The slider 122 is provided with a mating surface 122 a , and the mating surface 122 a faces the interior of the first prying frame 111 .

[0066] The slider 122 is inserted into the receiving groove 111a along the first direction and is fixed to the first pry frame 111 by the fixing member 121. That is, the slider 122 is insertable and can be inserted into the receiving groove 111a along the first direction. At the same time, the fixing member 121 can fix the slider 122 in the receiving groove 111a by connecting with the first pry frame 111.

[0067] The connection between the fixing member 121 and the first prying frame 111 is a detachable connection. For example, the fixing member 121 and the first prying frame 111 can be connected by a fastener.

[0068] Exemplarily, the fixing member 121 is connected to the first pry frame 111 by a fastener, and the disassembly and assembly direction of the fastener is the first direction, that is, the disassembly and assembly working space of the fastener is on the side of the mating surface 122a, so that the fixing member 121 can abut against the slider 122 on one side along the first direction along the first direction, and the slider 122 abuts against the accommodating groove 111a on the other side along the first direction, thereby achieving the fixation of the slider 122. At the same time, the disassembly and assembly working space of the fastener is larger, and the disassembly and assembly of the fixing member 121 is more convenient.

[0069] Therefore, by setting the accommodating groove 111a on the first pry frame 111, the slider 122 is inserted into the accommodating groove 111a along the first direction. The slider 122 is an insertable type, which makes the installation of the slider 122 more convenient. At the same time, the fixing member 121 can be connected to the first pry frame 111 to fix the slider 122 in the accommodating groove 111a. The disassembly and assembly working space of the fixing member 121 is on the side of the mating surface 122a, which makes the disassembly and assembly working space of the fixing member 121 larger and the disassembly and assembly of the fixing member 121 more convenient.

[0070] For some examples, see Figures 1 to 6The first prying frame 111 includes a first frame 1111 and a limiting member 1112. The limiting member 1112 is provided on the first frame 1111 and defines a receiving groove 111a with the first frame 1111. The receiving groove 111a has a mounting opening 111b on one side along the first direction. The slider 122 can be inserted into the receiving groove 111a through the mounting opening 111b. The fixing member 121 is connected to the first frame 1111 and abuts against a side of the slider 122 near the mounting opening 111b.

[0071] The first skid 111 includes a first frame 1111 and a limiting member 1112 , wherein the first frame 1111 includes a column extending along a height direction of the skid assembly 10 .

[0072] The second skid assembly 10 includes a second frame. The second frame includes columns extending in a height direction of the skid assembly 10 .

[0073] Exemplarily, the limiting member 1112 is a limiting rib, which is welded to the plate-shaped member of the first frame 1111 . The limiting rib and the first frame 1111 together define a receiving groove 111 a for receiving the slider 122 .

[0074] Exemplarily, the first frame 1111 constitutes the bottom wall of the accommodating groove 111a, thereby limiting the slider 122 in a direction perpendicular to the mating surface 122a; the limiting member 1112 constitutes the side wall of the accommodating groove 111a, thereby limiting the slider 122 in the direction of the plane where the mating surface 122a is located.

[0075] The accommodating groove 111a has an installation opening 111b on one side along the first direction, and the slider 122 can be inserted into the accommodating groove 111a through the installation opening 111b, wherein the installation opening 111b can be formed by the limiting member 1112, the first frame 1111, or the limiting member 1112 and the first frame 1111 are jointly formed.

[0076] It should be noted that a limiting member 1112 is at least partially provided on one side of the receiving groove 111a away from the installation opening 111b along the first direction, so as to position the slider 122 inserted into the receiving groove 111a, which is beneficial to the installation of the slider 122.

[0077] The fixing member 121 is connected to the first frame 1111 and abuts against the side of the slider 122 close to the installation opening 111b. That is, after the fixing member 121 is connected to the first frame 1111, the fixing member 121, the slider 122 and the limiting member 1112 abut against each other in sequence.

[0078] Here, by setting the limiting member 1112 on the first frame 1111 and defining the receiving groove 111a with the first frame 1111, the structure of the receiving groove 111a is made more reasonable, and the difficulty of production and manufacturing is reduced. At the same time, an installation port 111b is set on one side of the receiving groove 111a along the first direction, so that the slider 122 can be smoothly inserted into the receiving groove 111a through the installation port 111b, which is conducive to the installation of the slider 122.

[0079] For some examples, see Figures 1 to 7 The fixing member 121 includes a first connecting portion 1211 and an abutting portion 1212. The first connecting portion 1211 extends in a direction perpendicular to the mating surface 122a and is connected to the first frame 1111. One end of the abutting portion 1212 is connected to the first connecting portion 1211, and the other end extends in a first direction toward the receiving groove 111a and abuts against the side wall of the slider 122.

[0080] It should be noted that the cross section of the fixing member 121 may be substantially L-shaped, and the first connecting portion 1211 and the abutting portion 1212 may be two mutually perpendicular plate-shaped members of the L.

[0081] The plane where the first connecting portion 1211 is located and the plane where the abutting portion 1212 is located may be completely perpendicular or substantially perpendicular to each other.

[0082] The first connecting portion 1211 and the abutting portion 1212 may be integrally formed or may be designed as separate parts.

[0083] Exemplarily, the first connecting portion 1211 and the abutting portion 1212 are respectively plate-shaped members and are welded to form the fixing member 121 .

[0084] The connection between the first connecting portion 1211 and the first frame 1111 is a detachable connection, for example, a fastener connection or a snap connection, etc., which is not limited here.

[0085] Exemplarily, holes that cooperate with fasteners are formed on the first connecting part 1211 and the first frame 1111, and the locking part passes through the holes on the first connecting part 1211 and the holes on the first frame 1111, and is fastened to the first connecting part 1211 and the first frame 1111.

[0086] It should be noted that the other end of the abutting portion 1212 extends along the first direction toward the receiving groove 111 a and is used to abut against the side wall of the slider 122 close to the installation opening 111 b.

[0087] In this way, the first connecting portion 1211 extends in a direction perpendicular to the mating surface 122a and is connected to the first frame 1111, and the fixing member 121 fits against the first frame 1111, making the connection between the fixing member 121 and the first frame 1111 more reliable. At the same time, the abutting portion 1212 extends along the first direction toward the accommodating groove 111a, thereby achieving abutment with the side wall of the slider 122. The structure of the fixing member 121 is simpler, and it is convenient for the disassembly and assembly of the fixing member 121.

[0088] For some examples, see Figures 1 to 6 An opening 111 c is formed on one side of the receiving groove 111 a facing the second prying frame 112 , and at least the mating surface 122 a of the slider 122 extends beyond the opening 111 c .

[0089] An opening 111 c is formed on a side of the receiving groove 111 a facing the second prying frame 112 , that is, an opening 111 c is formed from the receiving groove 111 a toward the interior of the first prying frame 111 .

[0090] At least the mating surface 122a of the slider 122 extends beyond the opening 111c, so that the slider 122 can extend out of the accommodating groove 111a and cooperate with the outer facade of the column 1121 of the second pry frame, further avoiding direct contact between the first pry frame 111 and the second pry frame 112, and increasing the reliability of the sliding fit of the pry frame assembly 10.

[0091] In some embodiments, the fixing member 121 is connected to the slider 122 .

[0092] It should be noted that the fixing member 121 and the slider 122 are connected together, so that when the fixing member 121 is removed along the first direction, the slider 122 can also be taken out of the accommodating groove 111a along the first direction following the fixing member 121, which is convenient for taking out the slider 122.

[0093] For some examples, see Figures 3 to 8 A second connecting portion 122c is formed at one end of the slider 122 along the first direction. The second connecting portion 122c is used to connect with the auxiliary tooling and be taken out of the accommodating groove 111a through the auxiliary tooling.

[0094] Exemplarily, the second connecting portion 122c is a threaded hole, which is arranged on a side close to the mounting port 111b. The auxiliary tooling is a screw. After removing the fixing member 121, the auxiliary tooling is threadedly connected to the second connecting portion 122c of the slider 122 through the mounting port 111b. The slider 122 is driven to slide in the first direction by driving the auxiliary tooling, thereby taking the slider 122 out of the accommodating groove 111a.

[0095] The second connecting portion 122 c formed by the slider 122 is connected to the auxiliary tooling, so that the slider 122 can be taken out of the accommodating groove 111 a along the first direction, simplifying the structure of the slider 122 and the fixing member 121 .

[0096] For some examples, see Figure 8 The matching surface 122a is recessed toward the receiving groove 111a to form a groove 122b.

[0097] It should be noted that the shape of the groove 122b can be square, circular, polygonal, or a combination of arcs and straight lines, etc., and is not limited here.

[0098] Exemplarily, the groove 122b is in an X-shape.

[0099] It should be noted that the groove 122b can be used to accommodate lubricating grease.

[0100] In this way, by recessing the mating surface 122a toward the accommodating groove 111a to form a groove 122b, the groove 122b is used to accommodate lubricating grease, which is beneficial for the sliding cooperation of the first pry frame 111 and the second pry frame 112 along the height direction of the pry frame assembly 10, thereby improving the durability of the slider unit 12.

[0101] In some embodiments, the slider unit 12 is disposed on the top of the first pry frame 111 or the bottom of the second pry frame 112 .

[0102] For example, see Figures 1 to 6 The slider unit 12 is arranged on the first pry frame 111 and is located at the top of the first pry frame 111, so that when the second pry frame 112 slides upward along the height direction, the slider unit 12 on the first pry frame 111 can cooperate with the column 1121 of the second pry frame as much as possible.

[0103] Exemplarily, the slider unit 12 is arranged on the second skid 112 and is located at the bottom of the first skid 111, so that when the second skid 112 slides upward in the height direction, the slider unit 12 on the second skid 112 can cooperate with the column 1113 of the first skid as much as possible.

[0104] Therefore, by setting the slider unit 12 at the top of the first skid frame 111 or the bottom of the second skid frame 112, the slider unit 12 can cooperate with the column as much as possible within the lifting and lowering range of the second skid frame 112, thereby enhancing the stability of the cooperation between the slider unit 12 and the column and improving the performance of the skid frame assembly 10 in resisting lateral wind.

[0105] For some examples, see Figures 1 to 6The first skid 111 is rectangular and includes columns extending along the height of the skid assembly 10. Each column 1113 of the first skid has two mutually perpendicular mounting surfaces 1113a at the corners of the rectangle. Each mounting surface 1113a is provided with a slider unit 12.

[0106] It should be noted that the first skid frame 111 is rectangular, which means that the cross section of the first skid frame 111 in the direction perpendicular to the height of the skid frame assembly 10 is rectangular.

[0107] The first prying frame 111 may be rectangular, circular, elliptical, polygonal or other shapes, which are not limited here.

[0108] It can be understood that when the first skid frame 111 is rectangular, the slider unit 12 needs to be limited in at least four directions perpendicular to each side of the rectangle, so as to guide the second skid frame 112 during lifting, thereby improving the stability and safety of the skid frame assembly 10 during the lifting process.

[0109] Exemplarily, there are three slider units 12, which are arranged around the inner side of the first pry frame 111 and located between the first pry frame 111 and the second pry frame 112. A single slider unit 12 can limit the second pry frame 112 located in the first pry frame 111 along a direction perpendicular to the mating surface 122a. The three slider units 12 can jointly limit the second pry frame 112 located in the first pry frame 111 in three directions that are not parallel and not perpendicular to each other, thereby achieving guidance of the second pry frame 112 along the height direction.

[0110] Exemplarily, there are four slider units 12 , and the four slider units 12 can collectively limit the second skid frame 112 in four different directions, thereby achieving lifting and lowering guidance of the second skid frame 112 in the height direction.

[0111] The columns 1113 of the first skid frame have two mutually perpendicular mounting surfaces 1113a at the corners of the rectangle, and each mounting surface 1113a is provided with a slider unit 12, which means that each side of the rectangle is provided with a slider unit 12 near the corner of the rectangle, and two slider units 12 are provided at the four corners of the rectangle, and the mounting surfaces 1113a of the columns where the two slider units 12 are provided are perpendicular to each other.

[0112] In this way, by arranging a slider unit 12 on each side of the rectangular first skid 111 near the corner of the rectangle, the slider unit 12 can be limited in four directions perpendicular to each side of the rectangle, thereby guiding the second skid 112 when it is lifted or lowered, further improving the stability and reliability of the skid assembly 10 during the lifting process.

[0113] For some examples, see Figure 2 and Figure 9 The skid assembly 10 also includes a follower hose 13. The ends of the follower hose 13 are connected to the first skid 111 and the second skid 112, respectively. A sandwich 10a is formed between the first skid 111 and the second skid 112. The follower hose 13 is disposed within the sandwich 10a and can extend or retract along the height direction with the second skid 112.

[0114] It should be noted that, since a sliding unit is provided between the first pry frame 111 and the second pry frame 112 , direct contact between the first pry frame 111 and the second pry frame 112 is avoided when the second pry frame 112 is raised or lowered, thereby forming an interlayer 10a between the first pry frame 111 and the second pry frame 112 .

[0115] In addition, the follower hose 13 in the skid assembly 10 is used to connect to the oil cylinder, and the oil cylinder is used to drive the second skid 112 to rise and fall in the height direction.

[0116] For example, the follower hose 13 can be arranged like a drag chain, so that when the second skid 112 is raised or lowered in the height direction, the follower hose 13 can follow the second skid 112 to extend the pipeline or fold and retract the pipeline.

[0117] Here, by arranging the follower hose 13 in the interlayer 10a between the first skid 111 and the second skid 112, the central internal space of the skid assembly 10 is not occupied, thereby improving space utilization and increasing the space in the central internal space of the skid assembly 10.

[0118] A second aspect of the embodiments of the present application provides an injection head tower, the injection head tower comprising a base frame and a skid assembly 10 provided in any embodiment of the present application. The skid unit 11 is connected to the base frame.

[0119] It should be noted that, in the skid assembly 10 , the skid unit 11 at the bottom layer may be connected to the base frame, and the base frame fixes and supports the skid assembly 10 .

[0120] Exemplarily, the injection head tower further includes a working platform, which is disposed above the skid assembly 10 .

[0121] In the retracted state, at least a portion of the upper-level pry frame is sleeved within the lower-level pry frame; in the expanded state, at least a portion of the upper-level pry frame extends out of the lower-level pry frame.

[0122] The injection head tower provided in the embodiment of the present application is configured such that the slider unit 12 of the skid assembly 10 of the injection head tower is detachably arranged on the first skid 111 or the second skid 112 along the first direction. Correspondingly, the second skid 112 or the first skid 111 is matched with the slider unit 12. In this way, the slider unit 12 can guide the second skid 112 along the height direction along the direction perpendicular to the mating surface 122a, thereby improving the stability and reliability of the sliding fit between the second skid 112 and the first skid 111 along the height direction of the skid assembly 10. At the same time, the slider unit 12 can be disassembled and assembled along the first direction, that is, from the side of the mating surface 122a. The slider unit 12 can be disassembled and assembled without splitting the first skid frame 111 and the second skid frame 112, thereby improving the situation where there is no space for disassembling and assembling the slider unit 12 in the direction perpendicular to the mating surface 122a between the first skid frame 111 and the second skid frame 112. This makes the installation and disassembly of the slider unit 12 more convenient, improves the efficiency of installing and replacing the slider unit 12, and thus improves the installation efficiency and maintenance efficiency of the injection head tower.
