Description

Technical Field

[0001] This disclosure relates to the field of hydraulic support adjustment, and more particularly to a hydraulic support adjustment platform. Background Technology

[0002] In commonly used hydraulic support adjustment devices, jacks are mostly used to move the hydraulic support to the adjustment platform before installation. However, hydraulic supports are characterized by a high center of gravity, heavy weight, and a tendency to tip over. Furthermore, due to uneven force distribution and unstable traction connection of the jacks, it is difficult for the hydraulic support to be aligned smoothly with the slope of the adjustment platform. Even if it is pulled up onto the slope, it will tilt, making it difficult to move the support uphill and even posing a safety hazard of tilting and tipping over.

[0003] In the hydraulic support adjustment devices commonly used in current fully mechanized mining faces, the pull-frame jack is generally used as the main traction equipment to drag the hydraulic support to be installed from the transportation position to a dedicated hydraulic support adjustment platform (or installation platform, positioning platform) for subsequent positioning, connection and lifting operations.

[0004] However, hydraulic supports are characterized by their tall structure, high center of gravity, heavy weight, and poor stability, making them prone to overturning or sliding during movement on slopes. Furthermore, in actual operation, inconsistent output forces or asynchronous actions of multiple jacks can cause the resultant force to deviate from the support's center of gravity. Inadequate design of traction connection points or loose or worn connectors can cause the traction force application point to shift or become dynamically unstable. This makes it difficult for the hydraulic support to move along the intended trajectory when pulled up the slope towards the adjustment platform. Even if it is managed to climb the slope, phenomena such as support base deflection and overall imbalance often occur. This not only severely affects installation efficiency and accuracy but also poses significant safety risks such as support tilting and uncontrolled slippage, seriously threatening the safety of on-site personnel and the integrity of the equipment. Utility Model Content

[0005] The purpose of this application embodiment is to provide a hydraulic support adjustment platform that allows the hydraulic support to move along a predetermined trajectory during the traction process on the adjustment platform slope, and avoids phenomena such as support base deflection and overall imbalance.

[0006] To address the aforementioned technical problems, this application provides the following technical solutions:

[0007] This application provides a hydraulic support adjustment platform, comprising:

[0008] A first guide portion, the first guide portion having a first guide groove;

[0009] The second guide portion is disposed on the first side of the first guide portion. The second guide portion is inclined from the first side away from the first guide portion to the side closer to the first guide portion. The second guide portion is provided with a second guide groove.

[0010] Two guide plates are connected between the first guide groove and the second guide groove, so that the first guide groove and the second guide groove are connected to form a continuous guide channel;

[0011] The width of the first guide groove is greater than the width of the second guide groove. The distance between the two guide plates gradually decreases from the end closer to the first guide part to the end farther away from the first guide part, thereby forming a tapered guide structure with a relatively wide entrance and a relatively narrow exit, which is used to guide the hydraulic support base into the second guide part.

[0012] In some modified embodiments of the first aspect of this application, the first guide portion has two first side plates, which are disposed on both sides of the first guide portion and are parallel to each other, and the two first side plates and the top surface of the first guide portion form a first guide groove.

[0013] In some modified embodiments of the first aspect of this application, the second guide portion includes:

[0014] The second side plate has two side plates arranged on both sides of the second guide section and parallel to each other. The horizontal projection of the second side plate is parallel to the first side plate.

[0015] The guide slope is inclined from a position away from the first guide part to a position closer to the first guide part, and the two second side plates and the guide slope form a second guide groove.

[0016] In some modified embodiments of the first aspect of this application, the top edges of the first side plate and the second side plate are provided with an inwardly folded anti-detachment structure to prevent the hydraulic support from sliding out of the guide channel.

[0017] In some modified embodiments of the first aspect of this application, two first side plates are symmetrically distributed on both sides of the first guide portion along a first line of symmetry.

[0018] Two second side plates are symmetrically distributed on both sides of the second guide section along the second line of symmetry.

[0019] The horizontal projections of the first and second lines of symmetry are collinear.

[0020] In some modified embodiments of the first aspect of this application, the guide plate is connected to the ends of the first side plate and the second side plate, respectively.

[0021] In some modified embodiments of the first aspect of this application, the inner surface contours of the two first side plates, the two guide plates, and the two second side plates are matched with each other, and together they enclose a guide channel with a relatively wide entrance and a relatively narrow exit.

[0022] In some modified embodiments of the first aspect of this application, the guide plate is a straight plate, an arc plate, or a bent plate, and its inner contour can be adapted to the outer edge of the hydraulic support base.

[0023] In some modified embodiments of the first aspect of this application, the tilt angle of the second guide portion is 3°-15°.

[0024] In some modified embodiments of the first aspect of this application, the end of the second guide portion is provided with a positioning block or a limiting pin to limit the final position of the hydraulic support on the adjustment platform.

[0025] Compared to existing technologies, the hydraulic support adjustment platform provided in the first aspect of this application, by setting a first guide portion on one side of a second guide portion and providing guide grooves on both the first and second guide portions, such that the width of the first guide groove in the first guide portion is greater than the width of the second guide groove in the second guide portion, and by connecting the first and second guide grooves with two guide plates, makes the first and second guide grooves interconnected, forming a continuous guide channel. This causes the distance between the two guide plates to gradually decrease from the end closer to the first guide portion to the end farther away from the first guide portion, thereby enclosing and forming... A tapering guide structure with a relatively wide inlet and a relatively narrow outlet allows the hydraulic support to be coarsely guided by the first guide groove and then guided by the tapering guide structure, automatically adjusting the direction of the support's movement. This enables the hydraulic support to move along a predetermined trajectory during its traction along the second guide ramp. Furthermore, the second guide groove constrains the support as it is dragged on the ramp, preventing it from deviating from its intended path and avoiding phenomena such as support base deflection and overall imbalance. This improves installation efficiency and accuracy, and avoids major safety risks such as support tipping over, slippage, and loss of control, which could threaten the safety of on-site personnel and the integrity of the equipment.

[0031] Exemplary embodiments of this application will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of this application and to fully convey the scope of this application to those skilled in the art.

[0032] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this disclosure pertains.

[0033] In commonly used hydraulic support adjustment devices, jacks are mostly used to move the hydraulic support to the adjustment platform before installation. However, hydraulic supports are characterized by a high center of gravity, heavy weight, and a tendency to tip over. Furthermore, due to uneven force distribution and unstable traction connection of the jacks, it is difficult for the hydraulic support to be aligned smoothly with the slope of the adjustment platform. Even if it is pulled up onto the slope, it will tilt, making it difficult to move the support uphill and even posing a safety hazard of tilting and tipping over.

[0034] In the hydraulic support adjustment devices commonly used in current fully mechanized mining faces, the pull-frame jack is generally used as the main traction equipment to drag the hydraulic support to be installed from the transportation position to a dedicated hydraulic support adjustment platform (or installation platform, positioning platform) for subsequent positioning, connection and lifting operations.

[0035] However, hydraulic supports are characterized by their tall structure, high center of gravity, heavy weight, and poor stability, making them prone to overturning or sliding during movement on slopes. Furthermore, in actual operation, inconsistent output forces or asynchronous actions of multiple jacks can cause the resultant force to deviate from the support's center of gravity. Inadequate design of traction connection points or loose or worn connectors can cause the traction force application point to shift or become dynamically unstable. This makes it difficult to accurately align the hydraulic support with the slope centerline during traction onto the adjustment platform. Even if it is pulled up the slope, phenomena such as support base deflection, top beam tilting, and overall imbalance often occur. This not only severely affects installation efficiency and accuracy but also poses significant safety risks such as support tilting and uncontrolled slippage, seriously threatening the safety of on-site personnel and the integrity of the equipment.

[0036] To address the aforementioned technical problems, this application provides a hydraulic support adjustment platform, which prevents the hydraulic support from being precisely aligned with the slope centerline during the traction process onto the adjustment platform, and avoids phenomena such as support base deflection, top beam tilting, and overall imbalance.

[0037] like Figure 1 and Figure 2 As shown, a hydraulic support adjustment platform includes a first guide section (1), a second guide section (2), and guide plates (31). The first guide section (1) has a first guide groove (11). The second guide section (2) is disposed on the first side of the first guide section (1). The second guide section (2) is inclined from the position away from the first side of the first guide section (1) to the position close to the first guide section (1). The second guide section (2) is provided with a second guide groove (21). Two guide plates (31) are connected between the first guide groove (11) and the second guide groove (21) to connect the first guide groove (11) and the second guide groove (21) and form a continuous guide channel. The width of the first guide groove (11) is greater than the width of the second guide groove (21). The distance between the two guide plates (31) gradually decreases from the end close to the first guide section (1) to the end away from the first guide section (1), thereby enclosing a tapered guide structure (3) with a relatively wide entrance and a relatively narrow exit, which is used to guide the hydraulic support base into the second guide section (2).

[0038] The first guide section (1) is the entrance guide section of the support platform, located at the front end of the platform (near the transport tunnel side), used to receive the hydraulic support pulled by the support jack and provide initial positioning tolerance space. The first guide section (1) provides a wide guide entrance to accommodate the initial position deviation of the support, withstand the impact load when the support enters, and can serve as the starting end of the gradually narrowing guide channel, connecting with the guide plate (31). The first guide section (1) can be a channel steel structure, consisting of two parallel steel plates or sections of steel (such as I-beams or H-beams) forming a U-shaped or U-shaped groove, with the first guide groove (11) formed in the middle. The first guide section (1) can also be a track-type structure, using heavy-duty mining rails or customized guide rails, with the support base sliding along the rails. The first guide section (1) can also be a combined structure, welded from a base plate and side baffles, with the side baffles serving as the subsequent first side plate (111).

[0039] The second guide section (2) is the precise positioning section of the support platform. It is located behind the first guide section (1) (near the working surface) and is arranged at a certain angle to guide the support to the installation position and complete the centering. The second guide section (2) can achieve the final precise positioning of the support and complete the automatic correction with the tapering structure. It can also serve as a stable support area before the support is raised. The second guide section (2) can be inclined downward, that is, the side closer to the first guide section (1) is lower and the side closer to the second guide section (2) is higher. In some embodiments, the second guide section (2) can be inclined upward, that is, the side closer to the first guide section (1) is higher and the side closer to the second guide section (2) is lower. The second guide section (2) can be an inclined channel steel with a structure similar to the first guide section (1), but the whole is inclined towards the first guide section (1) (the inclination angle is usually 3° to 15°); the second guide section (2) can also be a ramp with a second guide groove (21) at the top. The second guide section (2) can also be a structure with a limiting block. The end is equipped with a stop pin or positioning block to prevent over-traction; the second guide part (2) can also be an embedded platform structure, partially embedded in the bottom beam of the main platform, and integrated with the lifting or locking mechanism.

[0040] The guide plate (31) is a transitional component connecting the first guide section (1) and the second guide section (2). It is arranged in pairs on the left and right sides to smoothly connect the two guide grooves and form a continuous tapering channel. The guide plate (31) can achieve a continuous transition from wide to narrow guide width, guiding the side edge of the support base to slide along a predetermined trajectory, avoiding jamming or impact caused by steps or sudden changes. The guide plate (31) can be a straight inclined structure, flat, with a straight inner edge forming an angle with the center line. The structure is simple and suitable for small shrinkage ratios. The guide plate (31) can also be an arc-shaped guide plate (31), with an inner contour of an arc or spline curve. The transition is smoother and the impact is reduced. The guide plate (31) can also be a bent guide plate (31), composed of multiple broken lines forming an approximate curve, taking into account both manufacturing convenience and guiding performance. The guide plate (31) can also be an adjustable structure, with the angle fine-tuned by bolts or hinges to adapt to different models of supports.

[0041] The first guide groove (11) is a transverse through groove structure set at the entrance end (first guide part (1)) of the adjustment platform, used to receive and initially constrain the hydraulic support base pulled by the jack. The first guide groove (11) can provide a large initial tolerance space to accommodate the positional deviation when the support enters; it can limit the large lateral (left and right) offset of the support base; the first guide groove (11) can serve as the starting section of the gradually narrowing guide channel and smoothly connect with the guide plate (31). The U-shaped groove can be welded from the base plate and the two side uprights, with a U-shaped cross section, which is simple to manufacture, has good rigidity, and is suitable for the mainstream form. The first guide groove (11) can also be a track embedded structure, in which two parallel heavy-duty guide rails can be embedded on the platform surface, with low friction, which is suitable for frequent adjustment operations.

[0042] The second guide groove (21) is a narrow guide groove located at the positioning end (second guide part (2)) of the adjustment platform. It is usually inclined towards the first guide part (1) and is used to achieve the final precise positioning and attitude correction of the hydraulic support. The second guide groove (21) can force the support base to be aligned with the center line of the platform and complete automatic correction with the tapering structure, providing a stable reference for subsequent lifting and connection operations. The two sides of the second guide groove (21) are inclined towards the first guide part (1). The end of the groove can be integrated with positioning pin holes or blocks to prevent over-traction and improve the accuracy of repeated installation. The second guide groove (21) can be a stepped narrow groove with steps at the bottom or opening to match the specific structure of the support and is suitable for customized support models.

[0043] The tapered guide structure (3) is a continuous converging channel with a wide inlet and a narrow outlet, formed by the first guide groove (11), the second guide groove (21), and the guide plate (31) connecting them. Its cross-sectional width gradually decreases along the direction of support movement, resembling a funnel or horn. The tapered guide structure (3) uses lateral reaction force to push the skewed support back to the center line, avoiding jamming, impact, or overturning caused by sudden changes. It can also prevent the base from rotating through continuous lateral constraints. The tapered guide structure (3) can be set on the top surface (112) of the first guide part (1) and communicate with the first guide groove (11) to form a connected guide channel.

[0044] Compared to the prior art, the hydraulic support adjustment platform provided in the first aspect of this application, by setting the first guide part (1) on one side of the second guide part (2), and providing guide grooves on both the first guide part (1) and the second guide part (2), makes the width of the first guide groove (11) of the first guide part (1) greater than the width of the second guide groove (21) of the second guide part (2), and by connecting the first guide groove (11) and the second guide groove (21) with two guide plates (31), makes the first guide groove (11) and the second guide groove (21) connected, forming a continuous guide channel, thereby making the distance between the two guide plates (31) increase from the end closer to the first guide part (1) to the end farther away from the first guide part. (1) One end gradually decreases, thus forming a tapered guide structure (3) with a relatively wide entrance and a relatively narrow exit. This allows the hydraulic support to be guided by the tapered guide structure (3) after being coarsely guided by the first guide groove (11). This automatically adjusts the forward direction of the support, allowing the hydraulic support to move along a predetermined trajectory during the traction process towards the second guide section (2). It also allows the support to be constrained by the second guide groove (21) when being dragged on the slope, preventing the support from deviating and avoiding phenomena such as base deflection, top beam tilting, and overall imbalance. This improves installation efficiency and accuracy, and avoids major safety risks such as support tilting, slippage and loss of control, which threaten the safety of on-site workers and the integrity of the equipment.

[0045] like Figure 1 and Figure 2 As shown, in some modified embodiments of this application, the first guide portion (1) has two first side plates (111), which are disposed on both sides of the first guide portion (1) and are parallel to each other. The two first side plates (111) and the top surface (112) of the first guide portion (1) form a first guide groove (11).

[0046] The above scheme adopts an open groove structure. Two first side plates (111) are fixed vertically (or approximately vertically) to both sides of the main body of the first guide part (1). The top surface (112) of the first guide part (1) (i.e., the top bearing surface of the platform) serves as the bottom of the groove. The three together form a U-shaped first guide groove (11) that is open at the top, closed at the bottom, and limited on both sides. This structure does not require an additional base plate and directly uses the main body of the adjustment platform as the bottom surface of the guide groove, simplifying the manufacturing process and reducing weight.

[0047] Two parallel first side plates (111) physically limit the left and right outer edges of the hydraulic support base, preventing it from shifting significantly laterally during traction. This is especially effective when the jacks apply uneven force, significantly suppressing the tendency for unilateral slippage. The top surface (112) of the platform serves as the bottom of the groove, ensuring that the support base always maintains surface contact with the adjustment platform. This avoids the risk of local stress concentration or overturning caused by suspension or point contact, while also providing a flat support surface for subsequent lifting. When the support base enters the first guide groove (11) with a slight deviation, one side will first contact the corresponding side plate. As it continues to move forward, under the oblique reaction force of the side plate (if combined with a tapered structure) or symmetrical resistance, it will naturally tend towards the center line, achieving initial self-centering.

[0048] like Figure 1 As shown, in some modified embodiments of this application, the second guide portion (2) includes a second side plate (211) and a guide ramp (212). The two second side plates (211) are disposed on both sides of the second guide portion (2) and are parallel to each other. The horizontal projection of the second side plate (211) is parallel to the first side plate (111). The guide ramp (212) is inclined from the first side away from the first guide portion (1) to the side closer to the first guide portion (1). The two second side plates (211) and the guide ramp (212) form a second guide groove (21).

[0049] Two second side plates (211) are set on both sides of the second guide section (2) and are parallel to each other; the guide slope (212) serves as the bottom surface of the second guide groove (21), which is inclined from the side away from the first guide section (1) to the side closer to the first guide section (1), and the three together form the second guide groove (21). By setting the guide slope (212) inclined towards the center line in the second guide section (2) and cooperating with the parallel second side plates (211) on both sides to form the second guide groove (21), when the hydraulic support enters this area, since the width of the second guide groove (21) is almost the same as the support base, the left and right sides of the hydraulic support are tightly clamped by the second side plates (211), and cannot move laterally or rotate, thereby achieving high-precision centering, attitude locking (preventing yaw angle), and preventing displacement during subsequent lifting.

[0050] In some embodiments, the width of the second guide groove (21) can be slightly larger than that of the support base (e.g., total width + 10 to 30 mm) to ensure guiding accuracy and avoid jamming due to manufacturing errors or coal sludge accumulation. The front end of the second side plate (211) can be provided with an inlet chamfer or arc transition to facilitate the smooth engagement of the support.

[0051] In some modified embodiments of this application, the top edges of the first side plate (111) and the second side plate (211) are provided with an inwardly folded anti-detachment structure to prevent the hydraulic support from sliding out of the guide channel.

[0052] The anti-detachment structure refers to the flange, eaves, or hook-like structure formed by the top edges of the first side plate (111) and the second side plate (211) folding inward along the horizontal direction or slightly downward (i.e., towards the centerline of the adjustment platform). For example, the anti-detachment structure can be a horizontally inwardly folded edge (such as an L-shaped or U-shaped bend), a downwardly folded eaves (forming an angle of 5° to 30° with the horizontal plane), or an anti-detachment hook with a rounded transition (balancing strength and smooth insertion). The folding width of the anti-detachment structure can be 20–60 mm, which is sufficient to cover the upper edge or side wings of the hydraulic support base. The anti-detachment structure can mechanically limit the upper part of the base when the hydraulic support tends to overturn due to traction eccentricity, uneven base plate, or center of gravity shift, effectively preventing the support from sliding out of the guide channel, significantly improving the safety and reliability of the adjustment process, while not affecting the normal insertion and movement of the support.

[0053] like Figure 1 As shown, in some modified embodiments of this application, two first side plates (111) are symmetrically distributed on both sides of the first guide portion (1) along the first symmetry line; two second side plates (211) are symmetrically distributed on both sides of the second guide portion (2) along the second symmetry line; wherein the horizontal projections of the first symmetry line and the second symmetry line are collinear.

[0054] The first line of symmetry is the geometric center line of the first guide section (1), which is also the axis of symmetry of the first guide groove (11); the second line of symmetry is the geometric center line of the second guide section (2), which is the axis of symmetry of the second guide groove (21); the collinearity of their horizontal projections means that the entire guide channel (from the entrance to the exit) strictly shares a center line in the horizontal plane, which is the overall symmetry center axis of the adjustment platform. This design ensures that the support is always guided to the same theoretical center trajectory throughout the entire process from wide-mouth introduction to narrow-mouth positioning, avoiding the S-shaped twisted path caused by the eccentricity of the front and rear sections.

[0055] By making the first line of symmetry of the first guide section (1) and the second line of symmetry of the second guide section (2) collinear on the horizontal projection, the entire adjustment platform forms a continuous guide channel symmetrical about a single central axis. This structure ensures that the hydraulic support is subjected to balanced force throughout the entire process from wide-mouth introduction to narrow-mouth positioning, effectively achieving automatic centering, and avoiding the risk of skewing, jamming, or overturning caused by eccentricity of the guide path, significantly improving the safety and reliability of the adjustment operation.

[0056] like Figure 1 As shown, in some modified embodiments of this application, the guide plate (31) is connected to the ends of the first side plate (111) and the second side plate (211), respectively. The two guide plates (31) are connected to the rear end of the first side plate (111) and the front end of the second side plate (211), respectively, so that the first side plate (111), the guide plate (31), and the second side plate (211) form a continuous lateral limiting boundary in the direction of support movement. This structure not only ensures the geometric continuity of the guide channel and effectively prevents the hydraulic support from swaying or detaching in the transition area, but also significantly improves the overall rigidity and lateral impact resistance of the adjustment platform.

[0057] like Figure 1 As shown, in some modified embodiments of this application, the inner surface contours of the two first side plates (111), the two guide plates (31), and the two second side plates (211) are matched with each other, and together they enclose a guide channel with a relatively wide entrance and a relatively narrow exit.

[0058] The smooth contour reduces scratches and local stress concentration. The support base and guide surface make surface or line contact rather than point contact or impact collision, and low-friction materials can be used to further reduce drag. By matching the inner contours of the two first side plates (111), the two guide plates (31), and the two second side plates (211), a continuous tapering guide channel is formed, achieving a smooth transition from a wide entrance to a narrow exit. This effectively eliminates guide breakpoints and stress concentration, and significantly improves automatic alignment accuracy and operational stability, fundamentally reducing the risk of frame misalignment, jamming, and overturning.

[0059] In some modified embodiments of this application, the guide plate (31) is a straight plate, an arc plate or a bent plate, and its inner contour can be adapted to the outer edge of the hydraulic support base.

[0060] Straight plates, with straight inner sides forming a linear tapering channel, are simple in structure and low in cost, suitable for conventional working conditions where the support base is rectangular (or approximately rectangular) with a small shrinkage ratio (≤1.5:1). Arc plates, with circular arcs or high-order spline curves on the inner side, have a smooth transition and no impact, suitable for heavy-duty supports, large shrinkage ratios, or high-precision alignment requirements. Guide plates (31) can also be bent plates, consisting of 2–3 straight bends forming an approximate curve, balancing manufacturing convenience and guiding performance, suitable for on-site processing or modular replacement. By providing various guide plate (31) forms, the platform can flexibly adapt to the base shape of different models of hydraulic supports (such as rectangular, chamfered, lug-equipped, etc.), improving versatility.

[0061] like Figure 1 and Figure 2 As shown, in some modified embodiments of this application, the tilt angle of the second guide (2) is 3°-15°.

[0062] The second guide section (2) is a sloping structure used to connect the entrance of the adjustment platform (or the bottom plate of the transport tunnel) with the installation position of the main body of the platform; the inclination angle refers to the angle between the slope and the horizontal plane; the slope surface is provided with a second guide groove (21) (formed by two second side plates (211) and the slope surface), used to guide the hydraulic support base to go up or down along the slope.

[0063] In fully mechanized mining faces, there is often a height difference of 0.3–2.5 meters between the cut and the face. Without a slope transition, additional elevation or excavation is required, which is time-consuming and labor-intensive. Setting a slope of 3°–15° can smoothly transition a 1-meter height difference within a length of 1.2–4.8 meters (tan15°≈0.268), balancing space and slope requirements. If the slope is too gentle, the required slope is too long, occupying a large amount of roadway space, which is not suitable for cuts with limited space. If the slope is too steep, the center of gravity of the hydraulic support is high, making it prone to instability and posing a risk of collapse.

[0064] In some modified embodiments of this application, the end of the second guide part (2) is provided with a positioning block or a limiting pin to limit the final position of the hydraulic support on the adjustment platform.

[0065] The positioning block can be a high-strength steel boss, welded or bolted to the end of the second guide part (2); the limiting pin can be a detachable cylindrical pin or tapered pin, inserted into the pre-set hole of the platform; when the front end of the support base (or a special limiting ear plate) contacts the positioning block or limiting pin, the movement is physically terminated, ensuring that the final position of the support on the adjustment platform is accurate and consistent. This structure not only effectively prevents over-traction caused by operation delay or jack inertia, but also provides a reliable positioning benchmark for subsequent lifting, connection and debugging operations, significantly improving installation efficiency and operational safety.

[0066] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
