Description

Technical Field

[0001] This utility model relates to the installation of large sealing components that penetrate the cabin in the field of marine engineering, and particularly to a self-guided sealing component spiral pusher. Background Technology

[0002] The installation of large marine sealing components and the casing of the penetration sealing components is limited by the inherent characteristics of the large sealing components themselves, the special location of the penetration sealing component casing, and the space constraints of the construction area. For this project, the installation of the series of products has always been carried out manually. The large sealing components are manually transported to the penetration sealing component casing, then centered by hand-carrying and lifting. After the proximal end is inserted, it is held in place by hand before being pulled in by hand-operated hoists. The entire installation process is conducted entirely manually.

[0003] However, in the process of implementing the inventive technical solution in the embodiments of this application, the inventors of this application discovered that the above-mentioned technology has at least the following technical problems:

[0004] This tooling method is labor-intensive, time-consuming, and inefficient. Furthermore, it poses a significant quality risk due to potential damage to the sealing ring during insertion caused by manual alignment errors and the high difficulty of manual control. Summary of the Invention

[0005] To address the shortcomings of existing technologies and the issue of mechanical methods replacing manual methods in the introduction and installation of large marine compartment sealing assemblies, this application provides a self-guided sealing assembly screw pusher. This screw pusher uses a separate combination of load-bearing and fixing components and guiding and stopping components. By rotating a screw, it pushes the sealing assembly to the assembly position on the sealing assembly housing, thus solving the technical problem of sealing assembly assembly.

[0006] The solution adopted by the embodiments of this application to solve the technical problem is:

[0007] A self-guided sealing assembly screw pusher includes a load-bearing and fixing component, a guiding and stopping component, a lifting ring, a handle, and a top screw plate; the load-bearing and fixing component includes a front pressure plate assembly, a core plate assembly, and a connecting rod;

[0008] The front pressure plate assembly abuts against the push sealing assembly to push it forward. The core plate assembly is embedded in the sealing assembly housing. The front pressure plate assembly and the core plate assembly are connected by a connecting rod to form a linkage structure. The guiding and stopping components include a guide support plate, guide rod, lead screw, bearing, and locking sleeve. A lead screw is located in the middle of the guide support plate, and a bearing is mounted on the lead screw. The lead screw is cantilevered onto the guide support plate by the locking sleeve. Guide rods are symmetrically arranged on the guide support plate for guiding the push process during the installation of the sealing assembly. The lead screw extends through the front pressure plate assembly and the core plate assembly to form a spiral push structure. A handle is located at the end of the lead screw for driving its rotation. A lifting ring is located at the end of the lead screw for adjusting the sealing ring of the sealing assembly to ensure it is fully in contact with the end face of the sealing assembly housing. A top screw plate is located at the outer end of the core plate assembly to provide a reverse pushing force during the installation of the sealing assembly. Rotating the handle, through the linkage of the lead screw with the load-bearing and fixing components, and the guiding and stopping components, pushes the sealing assembly to the assembly position on the sealing assembly housing.

[0009] To further address the technical problems to be solved in the embodiments of this application, the front pressure plate assembly provided in the embodiments of this application includes a front pressure plate and a screw nut; the front pressure plate is a long strip-shaped arc plate with stop steps at both ends of its arc, which match the inner diameter of the end face of the sealing component; the screw nut is located at the center of the front pressure plate and is screwed to the lead screw; symmetrical through holes for connecting rods are provided on the front pressure plate for assembling connecting rods.

[0010] Furthermore, the core plate assembly includes a core plate and a bushing; the core plate has a disc structure and is assembled inside the sealing assembly, matching the inner diameter of the sealing assembly bushing; a bushing is provided at the center of the core plate, and the bushing is assembled with a lead screw, with the lead screw extending out from the bushing.

[0011] The positive effects are significant. Because this embodiment employs a separate combination of load-bearing and fixing components, and guiding and stopping components, the sealing assembly achieves a mechanized installation process during centering and propulsion while in a sealed state. This effectively replaces manual installation. Furthermore, this spiral jacking device demonstrates advantages such as simple structure, convenient assembly and disassembly, strong operability, low manufacturing cost, and wide applicability during the construction of the sealing assembly. Using this spiral jacking device reduces the workload of six people for four days to two people for one day, which can be easily completed. This saves labor costs, reduces labor intensity, improves work efficiency, and ultimately enhances the quality of the sealing assembly. It is suitable for use as a self-guided spiral jacking device for sealing assemblies. 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. Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0042] The embodiments of this application solve problems that are prone to occur in the application of the prior art.

[0043] As shown in the figure, a self-guided sealing assembly spiral pusher includes a load-bearing and fixing component 100, a guiding and stopping component 200, a lifting ring 300, a handle 400, and a top screw plate 500.

[0044] The load-bearing and fixing component 100 includes a front pressure plate assembly 110, a core plate assembly 120, and a connecting rod 130;

[0045] The front pressure plate assembly 110 rests against the push sealing assembly to push the sealing assembly. The core plate assembly 120 is embedded in the housing of the sealing assembly. The front pressure plate assembly 110 and the core plate assembly 120 are connected together by the connecting rod 130 to form a linkage structure for fixing and bearing the load of the sealing assembly during installation.

[0046] The guide and stop component 200 includes a guide support plate 210, a guide rod 220, a lead screw 230, a bearing 240, and a locking sleeve 250;

[0047] A lead screw 230 is provided in the middle of the guide support plate 210. A bearing 240 is mounted on the lead screw 230, and the lead screw 230 is cantilevered on the guide support plate 210 through a locking sleeve 250. Guide rods 220 are symmetrically arranged on the guide support plate 210 for guiding the push process when installing the sealing assembly. The lead screw 230 extends through the front pressure plate assembly 110 and the core plate assembly 120 to form a spiral push structure, which provides a screwing push force when the sealing assembly is inserted into the sealing assembly housing, thereby embedding the sealing assembly in the sealing assembly housing.

[0048] The handle 400 is located at the end of the lead screw 230 and is used to drive the lead screw 230 to rotate;

[0049] The lifting ring 300 is located at the end of the lead screw 230 and is used to adjust the state in which the sealing ring of the sealing assembly is fully in contact with the end face of the sealing assembly housing.

[0050] The top screw plate 500 is located at the outer end of the core plate assembly 120 and is used to provide a reverse pushing force when the sealing assembly is installed.

[0051] The rotating handle 400, through the lead screw 230, is linked with the load-bearing and fixing component 100 and the guide and stop component 200 to push the sealing component to the assembly position of the sealing component housing, thereby realizing the assembly of the sealing component. At the same time, by combining and separating the load-bearing and fixing component 100 and the guide and stop component 200, it can be disassembled, so that the sealing, guiding and screwing of the sealing component can be completed in one go. The process is stable and reliable, and perfectly realizes the mechanical chemical method to replace the manual mode.

[0052] To ensure the stability of the structure in this embodiment, the front pressure plate assembly 110 includes a front pressure plate 111 and a nut 112. The front pressure plate 111 is a long, arc-shaped plate with stop steps at both ends of its arc, which match the inner diameter of the sealing component end face and are used to seal the sealing component. During the assembly of the sealing component, it plays a role in ensuring a stable connection and tight fit. The nut 112 is located at the center of the front pressure plate 111 and is screwed to the lead screw 230. The front pressure plate 111 has symmetrical through holes for connecting rods 130.

[0053] In this embodiment, the diameter of the stop of the front pressure plate 111 is φ0.10mm away from the coaxiality of the inner diameter of the sealing assembly, and the front pressure plate 111 and the nut 112 are positioned and welded together with a coaxiality of φ0.50mm.

[0054] To further ensure the stability of the structure in this embodiment, the core plate assembly 120 includes a core plate 121 and a bushing 122; the core plate 121 is a disc structure, assembled inside the sealing assembly, and matches the inner diameter of the bushing of the sealing assembly; a bushing 122 is provided at the center of the core plate 121, and the bushing 122 is assembled with the lead screw 230, with the lead screw 230 extending out of the bushing 122;

[0055] In this embodiment, the coaxiality deviation between the outer diameter of the core plate 121 and the inner diameter of the sealing assembly bushing is φ0.10mm, and the core plate 121 and the bushing 122 are positioned and welded together with a coaxiality of φ0.50mm.

[0056] As a conventional technical choice, the connecting rod 130 is a round shaft with internal threads at both ends. It is screwed to the front pressure plate 111 and the core plate 121 by connecting rod bolts 131, forming a robust and reliable combined structure.

[0057] To optimize the structure of this embodiment, the guide support plate 210 is a rectangular plate, and guide rod through holes are symmetrically arranged on the guide support plate 210. The guide rod 220 is a threaded shaft that passes through the guide rod through hole, and one end is locked on the guide support plate 210 by the guide stop nut 221.

[0058] Specifically, the other end of the guide rod 220 is connected to the fastening bolt hole on the end face of the sealing assembly housing to support the guide support plate 210.

[0059] In this embodiment, the center distance between the guide rod through hole and the center distance between the sealing assembly end face fastening bolt hole is ±0.5mm.

[0060] To further optimize the structure of this embodiment, the locking sleeve 250 is a single-sided separable nut, which is used to provide reverse thrust during the installation of the sealing assembly and is radially locked and fixed by the locking sleeve bolt 251.

[0061] To further optimize the structure of this embodiment, the top screw plate 500 is a rectangular plate with bolt through holes arranged on it. One end of the top screw plate 500 is connected to the core plate 121 by bolts, and the other end is connected to the sealing component housing to limit the position of the core plate 121.

[0062] The working principle of this embodiment:

[0063] As a helical jacking component, the lead screw 230, through the linkage of the load-bearing and fixing component 100 and the guiding and stopping component 200, enables the sealing component to have a full range of adjustment and a mechanized automatic installation process during installation, thus effectively replacing the manual installation mode.

[0064] Implementation process of this embodiment:

[0065] The front pressure plate 111 and the nut 112 are welded together through the center hole of the front pressure plate 111 to form a front pressure plate assembly 110. The front pressure plate 111 is machined with a stop step according to the inner diameter of the end face of the sealing component, forming a 0.1mm gap fit with the inner diameter of the end face of the sealing component, which plays a role in ensuring a stable connection and tight fit during the assembly process.

[0066] The front pressure plate 111 is combined with the core plate 121 via two connecting rods 130 to form a push-fixing assembly for the sealing component. The outer diameter of the core plate 121 and the inner diameter of the sealing component bushing meet a clearance fit of 0.1mm, so that the coaxiality of the sealing component and the sealing component housing remains consistent.

[0067] The load-bearing and fixing component 100 is fastened to the front pressure plate 111 and the core plate 121 by connecting rod bolts 131 at both ends of the core plate 121, so that the front pressure plate 111 and the core plate 121 are in close contact with the two end faces of the sealing assembly and are fastened. Then the set screw plate 500 on the end face of the core plate 121 is tightened until the load-bearing and fixing component 100 and the sealing assembly are tightly integrated.

[0068] Then screw the lead screw 230 into the core plate 121 through the nut 112 on the front pressure plate 111 to the appropriate position, and leave the required stroke distance for the sealing assembly to be inserted at the bow end.

[0069] Next, screw the guide rod 220 into the two tight-fitting bolt holes on the end face of the sealing assembly, directly above and below. Install the guide support plate 210. The guide support plate 210 has two through holes at both ends, with a radial spacing equal to the center distance between the two guide rods 220. Pass the two guide rods 220 through the holes and tighten the guide stop nut 221. Install the rolling bearing 240 at the center of the guide support plate 210, insert the lead screw 230 to the thrust end, and tighten the locking sleeve 250. This locking sleeve 250 acts as a thrust stop for the bearing 240, so that the guide support plate 210 generates a pushing force opposite to the screw 230's screwing direction during the process of the lead screw 230 driving the sealing assembly into the sealing assembly housing, thereby continuously pushing the sealing assembly into the sealing assembly housing.

[0070] Next, install the lifting ring 300 and handle 400. Rotate the handle 400 to drive the lead screw 230 to rotate, and the sealing assembly moves along the guide rod 220. When the first end of the sealing assembly is fully inserted into the sealing assembly housing and aligned with the first sealing ring, check the fit between the sealing ring and the housing end face. Adjust the sealing ring using the lifting ring 300 until it is fully fitted to the housing end face. Apply lubricating grease to the sealing ring, and then slowly rotate the handle 400 to push in the first sealing ring. Push in the second and third sealing rings in the same way. After all three sealing rings are pushed into the sealing assembly housing, rotate the lead screw 230 to push the sealing assembly until its end face is flush with the end face of the sealing assembly housing. Tighten the locking sleeve bolt 251, loosen the top screw plate 500 on the end face of the core plate 121, and then rotate the lead screw 230 in the opposite direction to remove the sealing assembly push assembly consisting of the core plate 121 and the front pressure plate 111. Remove the bearing locking sleeve 250, remove the guide support plate 210, remove the guide rod 220, remove the lead screw 230, and remove the push assembly to complete the installation of the sealing assembly. The removal process of the sealing assembly is the reverse of this. Without loosening the top screw plate 500 on the core plate 121, rotate the lead screw 230 in the opposite direction to pull the sealing assembly out of the sealing assembly housing.

[0071] It is worth noting that all contents not described in detail in the specification are existing technologies known to those skilled in the art, and the model parameters of lead screw 230, lead nut 112, guide stop nut 221, locking sleeve 250 and bearing 240 are not specifically limited and can be determined using conventional technology. Electrical control components not mentioned in this technical solution are not shown in the figure because they are existing technologies, and will not be described here.

[0072] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
