[0032] Furthermore, the positioning unit is fixed in the positioning area, which is located at least on one side of the installation area. This ensures the stability of the positioning unit during the installation of the seal and reduces the risk of damage to the installation area and seal caused by errors in the installation direction of the seal due to shaking or tilting of the positioning unit. Simultaneously, when operators manually apply the initial force to the installation unit, it is easy for deviations or excessive localized force to occur (excessive localized force refers to the initial force being concentrated in a localized area of ​​the seal, causing inconsistencies in the distance between different areas of the seal facing the installation area and the distance between the installation area and the seal facing the installation area, resulting in a deviation in parallelism between the seal and the installation area, making it difficult to install the seal properly and requiring reinstallation). However, when operators use the seal installation tool of this invention to install the seal, they can continuously correct the direction and magnitude of the initial force based on feedback from the detection unit. This reduces the risk of incomplete seal installation due to deviation in the direction of the initial force or force application, requiring reinstallation, and damage to the seal and installation area. Consequently, it reduces the increase in maintenance costs and the reduction in installation efficiency caused by damage to the seal and installation area. Attached Figure Description

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] like Figures 1-6 As shown, this utility model discloses a sealing element installation tool, which includes: a positioning unit, wherein a plurality of positioning units arranged along a first direction are fixed in a positioning area, the positioning area being at least located on one side of the installation area; an installation area for installing a sealing element 1; an installation unit, the installation unit being located on the positioning unit, the installation unit having an installation area for abutting against the sealing element 1 on the side facing the installation area, the installation unit being movable along the first direction under a first force; after the operator aligns the sealing element 1 with the installation area using equipment such as a level or by visual observation (aligning the sealing element 1 with the installation area can be understood as the center line of the sealing element 1 and the center line of the installation area coinciding; when both the sealing element 1 and the installation area are structures with an axis such as a circular structure, aligning the sealing element 1 with the installation area can be understood as the sealing element 1 being coaxially arranged with the installation area), the first direction is perpendicular to the end of the sealing element 1 facing the installation area and the side of the installation area facing the sealing element; and a detection unit, the detection unit being used to detect the parallelism between the installation unit and the installation area.

[0044] In this invention, the positioning unit is arranged along a first direction, which is perpendicular to the end of the sealing element 1 facing the installation area. The installation area is perpendicular to the side of the sealing element facing the installation area. The installation unit is mounted on the positioning unit (the installation unit being mounted on the positioning unit does not mean that the installation unit is above the positioning unit, but rather that the installation unit is mounted on the positioning unit). The side of the installation unit facing the installation area has an installation area for abutting against the sealing element 1. The installation area and the installation unit can move along the first direction under the first force. This allows the sealing element 1 to move along the first direction under the push of the first force and the installation unit until it reaches the installation position in the installation area. This ensures the installation effect of the sealing element 1 and reduces the problem of the sealing element 1 not being installed properly due to the misalignment of the installation direction during the installation process, requiring disassembly and reinstallation, thus reducing installation efficiency. Furthermore, several positioning units are fixed in the positioning area, which ensures the stability of the positioning units during the installation process of the sealing element 1 and reduces the problem of the positioning units shaking or misaligning, leading to... An error in the installation direction of seal 1 can cause damage to the installation area and seal 1. Furthermore, when operators manually apply the initial force to the installation unit, it is easy for deviations or excessive localized force to occur (excessive localized force means the initial force is concentrated in a localized area of ​​seal 1, causing inconsistencies in the distance between different areas of seal 1 facing the installation area and the distance between the installation area and the seal 1, resulting in a deviation in parallelism between seal 1 and the installation area, making it difficult to install seal 1 properly and requiring reinstallation). However, when using the seal installation tool of this invention to install seal 1, the operator can continuously correct the direction and magnitude of the initial force based on feedback from the detection unit. This reduces the problems of incomplete installation of seal 1 due to deviations in the direction of the initial force or force application, requiring reinstallation, and damage to seal 1 and the installation area. Consequently, it reduces the problems of increased maintenance costs and reduced installation efficiency caused by damage to seal 1 and the installation area.

[0045] Depending on the specific operating conditions, the installation area in this invention can be located in areas of different equipment requiring sealing, such as in oil pipe hangers 9 or hydraulic systems. Specifically, the installation area can be a mounting groove or mounting step to accommodate the corresponding sealing element 1, and its cross-sectional shape can be circular, square, or other shapes required for the operating conditions. Furthermore, the sealing element 1 in this invention can be a sealing ring, a skeleton oil seal, or a Glyd ring, etc., possessing sealing properties. The sealing ring can be a metal seal or a non-metal seal as needed, and when the sealing element 1 is a sealing ring, its cross-sectional shape is not limited to circular or square; it can also be other shapes required for the operating conditions. However, it should be noted that the shape and dimensions of the sealing element 1 and the installation area must be carefully configured to ensure that the sealing element 1, after being installed within the installation area, can effectively cooperate with the installation area to achieve the required sealing performance.

[0046] Depending on the shape and structure of the positioning unit, its installation location, and the installation requirements of the seal 1, the number of positioning units can be one or more. For example, when the positioning unit is a positioning rod located inside the installation area and avoids the installation area, only one positioning rod can be provided; when the positioning unit is a positioning rod located outside the installation area, one or more positioning rods can be evenly distributed around the center line of the installation area. The positioning unit can be a positioning rod, or it can be a shell with a circular cross-section. When the shell is fitted outside the installation area and avoids the installation area, a guide rail can be provided inside the shell, extending along a first direction and slidably connected to the installation unit in the first direction; when the shell is located inside the inner wall of the installation area and avoids the installation area, a guide rail can be provided outside the shell, extending along the first direction and slidably connected to the installation unit in the first direction. "The positioning area is at least located on one side of the installation area" means that a positioning area is provided outside the installation area and / or inside the installation area, with the positioning area avoiding the installation area. It should be noted that regardless of the number or shape of the positioning units, the positioning units must be set along the first direction. The connection between the positioning unit and the installation unit should enable the installation unit to move along the first direction on the positioning unit. During the installation of the seal 1, the positioning unit should not be displaced or tilted.

[0047] Avoidance settings refer to the setting of two objects so that their positions, installation, removal, and functions do not interfere with each other.

[0048] The positioning area refers to the area on the structure to be sealed that is separated from the installation area. The positioning area and the positioning unit can be connected by bolts, welding, or bonding, ensuring that the positioning unit does not tilt during the installation of the seal 1. Depending on the working conditions, the installation unit can be fitted over the positioning unit. For example, when the installation unit is a positioning plate 6 and the positioning unit is a positioning rod, the positioning plate 6 can be fitted over the positioning rod; alternatively, the installation unit can be located inside several positioning units. For example, when the installation unit is a positioning plate 6 and the positioning unit is a positioning rod, the positioning plate 6 can be located outside all the positioning rods. In this case, the positioning plate 6 can slide against the positioning rods in the first direction through its outer edge. The installation area refers to the area where the installation unit abuts against the seal 1 during installation. The first direction is perpendicular to the end of the seal 1 facing the installation area, and the side of the installation area facing the seal. This means that the seal 1 remains parallel to the installation area during installation, allowing the seal 1 to correctly enter the installation area in the posture required to achieve the desired sealing performance. When the cross-section of the installation area is circular, the first direction is the axial direction of the installation area; when the cross-section of the installation area is rectangular, the first direction is perpendicular to the side of the installation area facing the seal 1. Regardless of the shape of the installation area, during installation, the side of the seal 1 facing the installation area must be perpendicular to the first direction to ensure that the seal 1 can smoothly achieve the desired sealing performance after entering the installation area.

[0049] The detection unit can be a level, parallelism measuring instrument, or camera, etc., capable of detecting and providing feedback on the parallelism between the installation unit and the installation area. Depending on the operator's application of force to the installation unit—for example, applying a first force to multiple areas of the installation unit or to the central area—one or more detection units can be set. In this paper, during installation, the side of seal 1 furthest from the installation area is parallel to the side of seal 1 closest to the installation area (based on the structure of seal 1 itself), the side of seal 1 furthest from the installation area is parallel to the side of the installation unit facing the installation area (achieved through the structure of seal 1 itself and adjusting the orientation of the positioning unit and the installation unit), and the side of seal 1 closest to the installation area is parallel to the side of the installation area facing the seal 1 (achieved through the structure of seal 1 itself and adjusting the orientation of seal 1 and the installation unit). This means that this invention detects the parallelism between the installation unit and the installation area through the detection unit, which is essentially a detection of whether seal 1 and the installation area are parallel.

[0050] Depending on factors such as ease of assembly and disassembly and cost, the positioning unit and positioning area can be detachably fixed via bolts, or by welding, bonding, or other methods. Alternatively, the positioning unit includes a detachably connected positioning element 2 and a fixing element. The fixing element is detachably fixed to one side of the installation area, and the positioning element 2 is positioned along a first direction. This allows for easy disconnection of the positioning element 2 and fixing element in case of damage, enabling replacement of the damaged structure alone, thus reducing the maintenance cost of the positioning unit. Specifically, the fixing element can be a fixing block or plate fixed to the positioning area via bolts, and the positioning element 2 can be a positioning rod detachably connected to the fixing element. Correspondingly, if required by the operating conditions, the positioning unit can also be configured as an integrated structure, such as integrally molding or welding the fixing plate and positioning rod together.

[0051] The mounting unit and the seal 1 can be in point contact or surface contact. For example, when the mounting unit is a mounting rod with a small diameter, the mounting unit and the seal 1 are in point contact. Note that in this case, multiple mounting units need to be set to ensure that the seal 1 is subjected to uniform force in different areas, and to reduce the problem that the seal 1 may become misaligned during installation due to excessive local force, and thus fail to achieve the required sealing performance after installation. The mounting unit includes a first pressure plate that is simultaneously fitted onto all positioning units. An mounting area is located on the side of the first pressure plate facing the mounting area. The area of ​​the mounting area is not less than the area of ​​the seal 1 that contacts the mounting area. This means that the area of ​​the mounting area that contacts the seal 1 is not less than the area of ​​the seal 1 that contacts the mounting area. This allows different areas of the seal 1 to be evenly stressed when the mounting unit pushes the seal 1 in the first direction. This helps the side of the seal 1 facing the mounting area to remain perpendicular to the first direction and parallel to the side of the mounting area facing the seal 1 during installation, thereby ensuring the installation quality of the seal 1. And / or, with the center of the first pressure plate as the center, several positioning areas are evenly distributed on the outer side of the mounting area. This means that several positioning units are evenly distributed with the center of the first pressure plate, i.e., the intersection of the two diagonals of the first pressure plate, as the center. This allows the first pressure plate to be evenly stressed and reduces the risk of deformation when the operator applies a first force to the adjacent areas of the first pressure plate and each positioning unit, further ensuring the installation quality of the seal 1.

[0052] like Figures 1-6As shown, the installation unit includes a nut 7 mounted on the positioning unit. The nut 7 is threadedly connected to the positioning unit and is located on the side of the first pressure plate away from the installation area. The positioning rod can be a screw or other structure with external threads. At this time, the operator tightens the nut 7 to press the first pressure plate towards the installation area. Simultaneously, the first pressure plate presses the seal 1 towards the installation area until the seal 1 enters the installation area. The nut 7 must be tightened symmetrically to ensure force balance among the first pressure plate, the seal, and the installation area. When the seal 1 is in its initial position, it is located between the installation area and the first pressure plate, with the first pressure plate abutting against the end of the seal 1 away from the installation area. All nuts 7 are located in the same plane, and the area of ​​the first pressure plate and the installation area facing the seal 1 are parallel. The operator can pre-install a portion of the seal 1 near the installation area into the installation area to achieve initial alignment between the seal 1 and the installation area, ensuring that the seal 1 can subsequently move along the first direction. However, it is important to note that before tightening the nuts 7, and during the installation of the seal 1, the nuts 7 are not tightened one by one. Instead, all nuts 7 are gradually moved towards the installation area. For example, after turning one nut 7 two turns, all the remaining nuts 7 are turned two turns. Then, based on the feedback from the detection unit, it is determined whether the distance between different areas of the first pressure plate and the installation area is the same. That is, it is checked whether the first pressure plate and the seal 1 remain parallel to the side of the installation area facing the seal 1. If a local area of ​​the first pressure plate is too far from the installation area, the nuts 7 in that area are turned again until the distance between all areas of the first pressure plate and the installation area is the same, so as to ensure that the seal 1 and the installation area are parallel during the installation process and reduce the deformation of the seal 1 during the installation process. At this time, the detection unit can be placed on the side of the installation unit away from the installation area. When applying the first force to multiple areas of the installation unit, such as by tightening different nuts 7 to move the installation unit in the first direction, it can be done by only one operator or by operators with no less than a number of nuts 7 simultaneously.

[0053] Alternatively, the first pressure plate and the positioning unit are interference-fitted, and there is friction between the first pressure plate and the positioning unit. A first wear-resistant layer is provided between the first pressure plate and the positioning unit. The first friction increases the resistance for the operator to move the first pressure plate in the first direction, making it less likely for the first pressure plate to move excessively in the first direction under the action of excessive force by the operator. This provides a basis for the operator to adjust the first pressure plate in areas that are too far from the installation area, thus reducing the deformation and damage of the seal 1. The first wear-resistant layer reduces the direct friction between the first pressure plate and the positioning unit, extending the service life of the seal installation tool. The first wear-resistant layer can be a structural layer made of materials such as rubber or cast iron, and can be set on the first pressure plate and / or the positioning unit.

[0054] Furthermore, in this invention, the installation unit and the positioning unit are slidably connected in the first direction. For example, the installation unit is sleeved on the positioning unit, the positioning unit is provided with a slide rail, and the installation unit is provided with a slider that is slidably connected to the slide rail in the first direction. This achieves guiding and limiting of the installation unit and the seal 1, reducing the misalignment and damage of the seal 1 during installation. Even more importantly, if the working conditions permit, a pulley can be provided on the installation unit, so that the installation unit can slide along the first direction on the positioning unit via the pulley.

[0055] The sealing element installation tool includes a first limiting member located between the positioning area and the installation unit. When the sealing element 1 reaches a preset position, the first limiting member abuts against the installation unit. The first limiting member can be located in the positioning area or other positions that avoid the installation area. Specifically, the first limiting member can be a limiting rod or a limiting block, or other structures that can limit movement. The setting of the first limiting member prevents the sealing element 1 from moving excessively in the first direction, thereby reducing damage to the sealing element 1. The sealing element 1 reaching the preset position means that the sealing element 1 is installed within the installation area; and / or, the sealing element installation tool includes a second limiting member and a buffer member located between the positioning area and the installation unit. The buffer member is located on the side of the second limiting member closer to the installation unit. When the sealing element 1 reaches... When the device reaches the preset position, the buffer abuts against the installation unit. The second limiting device and the buffer can be set in the positioning area or other positions that avoid the installation area. The second limiting device can be a limiting rod or a limiting plate, etc. The buffer can be an elastic element such as a spring, or a vibration damping pad made of polyurethane material, etc. Alternatively, the buffer can also include a spring and a buffer plate. The buffer plate is located on the side of the second limiting device away from the installation area. The two ends of the spring are connected to the buffer plate and the second limiting device, respectively. The setting of the buffer allows the operator to increase the speed at which the seal 1 moves in the first direction as much as possible under the condition that the installation unit and the seal 1 undergo deformation that is permissible under working conditions, without worrying about the seal 1 being damaged by a hard collision.

[0056] The installation area is provided with a buffer layer, which may be a flexible pad such as a vibration damping pad, thereby reducing the wear caused by the installation unit during the installation of the seal 1; and / or, when the seal installation tool is in the initial position, the installation area is set perpendicular to the first direction, which ensures the parallelism between the installation unit, the seal 1 and the installation area, and ensures the installation accuracy of the seal 1; and / or, the positioning unit is provided with a scale line set along the first direction. By observing the scale line, the distance that the installation unit has moved in the first direction can be clearly determined, thereby adjusting the movement distance of the entire installation unit and local areas in real time.

[0057] The mounting unit has multiple first through holes for fitting onto the positioning unit. The mounting unit is provided with several reinforcing members that are arranged to avoid the first through holes and the mounting area. The first through holes can be arranged along the length of the mounting unit. In this case, the mounting unit is fitted onto the positioning unit through the first through holes, which allows the mounting unit and the positioning unit to be adapted to the installation of seals 1 of equipment of different sizes and types. The reinforcing members can be specific structures such as reinforcing ribs that can ensure the strength of the mounting unit.

[0058] And / or, the mounting unit includes: a second pressure plate and a third pressure plate, the third pressure plate being located inside the second pressure plate, the second pressure plate and the third pressure plate being slidably connected in a second direction, the second direction being perpendicular to the first direction, the second pressure plate having a second through hole, and the third pressure plate having a third through hole that mates with the second through hole; a locking member, which, after the third pressure plate extends a set length beyond the second pressure plate, is connected to the second pressure plate and the third pressure plate respectively, and prevents the second pressure plate and the third pressure plate from moving relative to each other; by moving the third pressure plate along the second direction, the overall extended length of the second pressure plate and the third pressure plate can be adjusted, thereby adapting to the installation of the seal 1 of equipment of different sizes; the locking member may specifically be a bolt or screw, etc., which can reduce the second pressure plate and the third pressure plate being fixed together, and is detachably fixedly connected to the second pressure plate and the third pressure plate.

[0059] The seal installation tool includes an assisting component, which comprises a support rod and a pressure rod. The support rod is located outside the installation area and is positioned along a first direction. The first end of the pressure rod is rotatably connected to the side of the installation unit furthest from the installation area. The pressure rod is rotatably connected to the support rod. The pressure rod includes a first pressure rod segment and a second pressure rod segment, which are sequentially arranged and connected from the installation area toward the support rod. The first pressure rod segment is located on the side of the support rod closer to the installation area, and the second pressure rod segment is located on the side of the support rod furthest from the installation area. The length of the second pressure rod segment is greater than the length of the first pressure rod segment. The support rod and the pressure rod are equivalent to a "lever structure," the installation unit is equivalent to a resistance point, the end of the pressure rod furthest from the installation unit is equivalent to a power point, and the rotatable connection point of the support rod and the pressure rod is equivalent to a fulcrum. Since the length of the second pressure rod segment is greater than the length of the first pressure rod segment, i.e., the length of the power segment is greater than the length of the resistance segment, the operator can push the installation unit in the first direction with a smaller force. The installation area and the support rod are configured such that the distance the installation unit can move in the first direction under the action of the pressure rod is not less than the stroke required for the seal 1 to reach the installation area, thereby ensuring that the seal 1 can be installed under the action of the assisting component. At this time, the mounting unit and the positioning unit are slidably connected in the first direction, or the mounting unit and the positioning unit are interference-fitted; or, the connection relationship between the mounting unit and the positioning unit may be other relationships that allow the mounting unit to move in the first direction under the action of the pressure rod.

[0060] like Figures 2-6As shown, at this time, the seal 1 includes several positioning units, each including a fixing member and a positioning member 2. The positioning member 2 is arranged along a first direction, and specifically, the positioning member 2 can be a positioning rod with external threads or other structures arranged along the first direction. The fixing member is used to fix the positioning member 2 in a non-installation area of ​​the equipment on which the seal 1 needs to be installed. The fixing member includes a first fixing member 3 and a second fixing member 4 that are detachably connected. The shape and size of the first fixing member 3 must match the equipment on which the seal 1 needs to be installed to ensure that the first fixing member 3 and the second fixing member 4 can be smoothly and stably installed in the positioning area. The first fixing member 3 can specifically be a first fixing hub, and the second fixing member 4 can specifically be a second fixing hub. The 4 can be fixed together by fasteners such as screws 5; the installation unit includes a positioning plate 6 that is simultaneously fitted on each positioning member 2, and a nut 7 is provided on the side of the positioning plate 6 away from the installation area. There are an even number of nuts 7 in total, which facilitates the symmetrical tightening of the nuts 7. The nuts 7 are threadedly connected to the positioning rod. There is a second wear-resistant layer 8, such as a gasket, between the nuts 7 and the positioning plate 6 to reduce the friction between the positioning plate 6 and the nuts 7. One end of the positioning rod is inserted into the first fixing member 3. The positioning rod is long enough so that the sealing member 1 can be placed between the positioning plate 6 and the installation area. The initial position of the positioning plate 6 must be parallel to the installation area. The positioning plate 6 abuts against the sealing member 1. The detection unit includes several levels provided on the positioning plate 6.

[0061] In this way, the operator can tighten all nuts 7 segment by segment in the first direction, and adjust the nuts 7 that are too far away from the installation area according to the feedback of the level during the tightening process, so that the seal 1 can be accurately installed into the installation area in the first direction, thereby ensuring the installation quality and reducing the damage to the seal 1 and the installation area.

[0062] like Figures 2-6 As shown, the sealing installation tool in this utility model can also be used for the installation of the metal seal on the neck of the tubing hanger. In this case, the sealing element 1 is a metal seal. The convex surface of the first fixing element 3 is installed on the concave surface 11 of the wellhead 10 to fix the sealing installation tool. The inclined surface of the second fixing element 4 contacts the inclined surface of the wellhead 10, preventing the sealing installation tool from loosening and the entire sealing installation tool from lifting up when a single nut 7 is tightened. The positioning plate 6 moves towards the installation area as the operator's force decreases, thereby installing the metal seal inside the tubing hanger 9. After installation, the sealing installation tool can be removed.

[0063] Appendix Figure 4 This refers to the structural diagram of the sealing installation tool in this utility model when it is used for the metal seal of the neck of the tubing hanger, with only the first fixing member 3 installed at the wellhead 10. Subsequently, the second fixing member 4 will be connected to the first fixing member 3 to achieve effective fixation of the sealing installation tool.
