Description

Technical Field

[0001] This invention specifically relates to an easy-to-maintain lower sealer based on cross-linked cable production. Background Technology

[0002] In the production process of dry cross-linked cables, the lower sealer is used to prevent the pressure in the vulcanizing tube from being discharged along the edge of the cable, so as to ensure the sealing pressure required for production. The main sealing part of the lower sealer usually uses rubber gaskets and steel gaskets as sealing components. The steel gasket is pressed by a hydraulic cylinder, which causes the rubber gasket to tighten and deform to achieve a seal.

[0003] In existing practical applications, the vulnerable sealing ring and its mating sliding sleeve are generally directly fixed between the front sealing tube and the main body of the sealer by multiple bolts. When replacing or performing routine maintenance, operators need to screw on and remove a large number of bolts in sequence. The entire disassembly and assembly process is extremely cumbersome, time-consuming, labor-intensive, and inefficient. Therefore, we propose an easy-maintain lower sealer based on cross-linked cable production. Summary of the Invention

[0004] The purpose of this invention is to provide an easy-to-maintain lower sealer based on cross-linked cable production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an easy-to-maintain lower sealer based on cross-linked cable production, comprising:

[0006] A base, wherein a guide rail is provided at one end of the upper surface of the base;

[0007] The closure body is mounted on the base, and the outer surface of the closure body is provided with a support plate that cooperates with the guide rail;

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] This invention, by incorporating guide rails, support plates, hydraulic cylinders, retaining rings, and sliding plates, avoids the traditional method of fixing the sliding sleeve and sealing ring between the front sealing pipe and the main body of the closure with bolts, which requires rotating multiple bolts during disassembly and assembly. This device eliminates the need to remove multiple bolts, allowing for quick removal of the sliding sleeve and sealing ring from one end of the closure body.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1-7 This invention provides a technical solution: an easy-to-maintain lower sealer based on cross-linked cable production, comprising:

[0033] Base 1, with a guide rail 4 provided on one end of the upper surface of base 1;

[0034] The closure body 3 is mounted on the base 1, and the outer surface of the closure body 3 is provided with a support plate 5 that cooperates with the guide rail 4;

[0035] The slide plate 10 is slidably mounted on one end of the upper surface of the guide rail 4, and the inner side of the slide plate 10 has a front sealing tube that connects to the outside.

[0036] The sliding sleeve 11 is movably fitted onto one end of the closure body 3, and one end of the sliding sleeve 11 is detachably connected to a sealing ring 12 that seals the inside of the closure body 3.

[0037] The hydraulic cylinder 6 is fixed on the support plate 5, and one end of the hydraulic cylinder 6 cooperates with the slide plate 10 to press the front sealing tube against the sealing ring 12. The front sealing tube has a pressure cap assembly that cooperates with one end of the sliding sleeve 11.

[0038] The retaining ring 7 is rotatably mounted on the outer surface of the closure body 3 so as to abut against the other end of the sliding sleeve 11;

[0039] This solution utilizes the hydraulic cylinder 6 to push the slide plate 10 along the guide rail 4, thereby achieving the pressing and releasing of the sealing ring 12 by the front sealing pipe. At the same time, the rotatable retaining ring 7 limits the sliding sleeve 11, effectively avoiding the operation of repeatedly rotating multiple bolts. This significantly simplifies the disassembly and installation process of the sliding sleeve 11 and the sealing ring 12, greatly improves maintenance efficiency and ease of operation, and enhances the practicality of the device.

[0040] Preferably, a secondary sealing box 2 is provided at the other end of the upper surface of the base 1, and one end of the sealing body 3 extends through the side wall of the secondary sealing box 2 to the inside of the secondary sealing box 2.

[0041] Preferably, a through hole for cable movement is provided in the middle of the inner side of the sealing ring 12.

[0042] Preferably, the pressure cap assembly includes a pressure cap 9 and a turntable 14. The pressure cap 9 is fixed to one side wall of the slide plate 10 by bolts, and a first adjusting handle 8 is rotatably installed on the inner side of the pressure cap 9. The turntable 14 has a locking block 111 fixed to one end of the outer wall of the sliding sleeve 11, and a notch for the locking block 111 to pass through is opened through one side wall of the turntable 14.

[0043] When unlocking is required, simply rotate the turntable 14 to align its notch with the locking block 111 for quick separation; the reverse is true during installation. This structure replaces the traditional bolt flange connection, greatly simplifying the disassembly and assembly of the front sealing tube and the sliding sleeve 11.

[0044] Preferably, a first adjusting handle 8 is provided on one side wall of the turntable 14;

[0045] It allows for quick and effortless rotation of the turntable 14 on-site to lock and unlock the cap assembly and the sliding sleeve 11.

[0046] Preferably, the card blocks 111 are evenly distributed in four places along the circumference of the sliding sleeve 11;

[0047] This allows the clamping force between the turntable 14 and the sliding sleeve 11 to be evenly distributed in the circumferential direction, ensuring stress balance, stable and reliable connection, avoiding skewing or loosening caused by single-point force, and guaranteeing structural stability under high-pressure sealing conditions.

[0048] Preferably, two retaining rings 7 are arranged side by side along the axial direction of the closure body 3, and a clearance groove 71 is provided on the side wall opposite to the two retaining rings 7.

[0049] During normal operation, the two retaining rings 7 can be used together to limit the movement. When disassembly is required, the two relief grooves 71 can be staggered by rotating the retaining rings 7, which can accommodate the protrusion between them, thereby increasing the axial movement space of the sliding sleeve 11 and making it easier to remove the sliding sleeve 11 without having to remove the retaining rings 7 as a whole.

[0050] Preferably, the outer surface of the retaining ring 7 is connected to a second adjusting handle 72 via a threaded portion;

[0051] The operator only needs to rotate the second adjusting handle 72 to precisely control the rotation angle of the retaining ring 7, so as to align or misalign the clearance groove 71, making the adjustment effortless.

[0052] Preferably, the inner edge of the sealing ring 12 has a connecting bolt, and one end of the sliding sleeve 11 has a groove, and the sealing ring 12 is fixed to the groove by the connecting bolt;

[0053] This facilitates the separate disassembly of the sealing ring 12 and the sliding sleeve 11.

[0054] Preferably, the inner wall of the sliding sleeve 11 is provided with a rubber ring 13 that contacts the closure body 3;

[0055] To prevent external impurities from entering the fit gap.

[0056] The working principle and usage process of this invention are as follows: When disassembling and assembling the sliding sleeve 11 and the retaining ring 7, the retaining ring 7 can be rotated by the second adjusting handle 72 to make the corresponding clearance grooves 71 of the two retaining rings 7 staggered to accommodate the protrusions between them, thereby expanding the moving space of the sliding sleeve 11 along the axial direction of the closure body 3. Then, the turntable 14 is rotated by the first adjusting handle 8 so that the notch of the turntable 14 corresponds to the locking block 111. Then, the hydraulic cylinder 6 is driven to extend, so that the front sealing tube can slide on the guide rail 4 through the sliding plate 10, and the sliding sleeve 11 and the retaining ring 7 can be removed from the closure body 3 for replacement and maintenance.

[0057] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
