Description

Technical Field

[0001] This utility model relates to the field of railway engineering technology, specifically to a GIS accessory for railway lines. Background Technology

[0002] GIS accessories for railway lines serve as bridges and barriers connecting critical equipment and cable lines in railway traction power supply and signaling power supply systems. They are used to ensure reliable connection, insulation protection, and operational safety between gas-insulated switchgear (GIS) and railway power supply cables.

[0003] In existing technologies, the sealing strips in GIS accessories for railway lines often experience repeated expansion and contraction due to temperature changes in the railway line environment during long-term use. This can cause the sealing strips to warp up in certain areas, reducing their sealing effect on the cables. Furthermore, some GIS accessories for railway lines use sealing strips that are typically designed as a single piece. If a single piece of sealing strip is partially damaged, it must be completely replaced. This not only increases the workload and difficulty of maintenance but also leads to higher maintenance costs. Utility Model Content

[0004] To address the aforementioned shortcomings of existing technologies, this utility model provides a GIS accessory for railway lines, which effectively solves the problem that requires complete replacement of the integrally molded sealing strip when partial damage occurs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a GIS accessory for railway lines, including a connecting pipe, an installation plate integrally formed on the outer end face of the connecting pipe, a fixed plate fixedly installed on the other end of the installation plate, a plurality of internal threaded blocks fixedly connected to the outer surface of the fixed plate, a threaded post threadedly connected to the inner surface of the internal threaded blocks, and a plurality of sealing blocks disposed on the inner side of the installation plate for sealing the cable connection end. The auxiliary mechanism includes a transmission assembly for transmitting rotational power when tightening the internal threaded block, and a clamp assembly capable of driving a plurality of the sealing blocks to contact the cable connection end as the transmission assembly rotates; the transmission assembly is located outside the mounting plate, and the clamp assembly is located between the mounting plate and the sealing blocks.

[0006] Furthermore, the accessory body is provided with two sets, and the two sets of connecting pipes are respectively sleeved at the connection points of the two cables.

[0007] Furthermore, the transmission assembly includes a toothed column fixedly connected to the outer end face of the threaded column, a gear meshing with the outer surface of one of the toothed columns, and a toothed disc meshing with the other side of the gear.

[0008] Furthermore, the transmission assembly also includes a through groove formed on the outer surface of the mounting plate, a limiting ring fixedly connected to the inner wall of the mounting plate and used in conjunction with the gear plate, and a support fixedly connected to the inner surface of the gear.

[0009] Furthermore, the gear disc is rotatably sleeved on the outer surface of the limiting ring, and a rotating bearing seat is installed at the connection between the support column and the mounting disc; When the toothed column is rotated, the threaded column can be screwed into the internal threaded block of another set of accessory bodies through the corresponding internal threaded block, thereby fixing the two sets of accessory bodies together. At this time, the gear is driven to rotate by one set of toothed columns, and then the gear drives the toothed disc to rotate around the limiting ring.

[0010] Furthermore, the clamp assembly includes several arc grooves formed on the outer surface of the gear disc, a force-bearing block movably connected to the inner wall of the arc groove, and a connecting rod fixedly installed on the outer surface of the force-bearing block by a bearing and used to fix the sealing block.

[0011] Furthermore, the clamp assembly also includes a positioning block fixedly connected to the outer surface of the connecting rod, and a positioning groove formed on the outer surface of the fixing plate and used in conjunction with the positioning block.

[0012] Furthermore, the number of the arc groove, the force-bearing block, and the connecting rod all correspond to the number of the sealing blocks. The outer surface of the positioning block slides in contact with the inner wall of the positioning groove. Multiple sealing blocks can be disassembled and replaced from the corresponding connecting rod surface. When the gear plate rotates, it can apply pressure to the force-bearing block through the inner wall structure of the arc groove, thereby causing the force-bearing block to drive the connecting rod and the positioning block to slide along the inner wall of the positioning groove, and finally drive the sealing block to contact the connection end of the cable through the connecting rod.

[0013] The technical solution provided by this utility model has the following advantages compared with the known prior art: By setting up an auxiliary mechanism, this utility model can not only automatically control multiple sealing blocks to make tight contact with the cable connection end when the rotating gear drives the two sets of accessory bodies to come together, but also independently disassemble and replace a single sealing block when it is damaged. This can significantly reduce maintenance workload and costs while ensuring the sealing performance of the accessory body. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] The present invention will be further described below with reference to the embodiments.

[0019] Example: A GIS attachment for railway lines, see attached document. Figure 1 -Appendix Figure 5 ,include, The cable includes a connecting tube 110, a mounting plate 120 integrally formed on the outer end face of the connecting tube 110, a fixing plate 130 fixedly installed on the other end of the mounting plate 120, a plurality of internal threaded blocks 140 fixedly connected to the outer surface of the fixing plate 130, a threaded post 150 threadedly connected to the inner surface of the internal threaded block 140, and a plurality of sealing blocks 160 disposed on the inner side of the mounting plate 120 for sealing the cable connection end. It should be noted that the accessory body 100, by providing two sets of symmetrical units, can respectively correspond to the connection ends of two cables. The connecting pipe 110 is used to provide basic positioning and support for cable docking and to limit the radial displacement of the cables. The mounting plate 120 is used to support the mounting fixing plate 130. The fixing plate 130 is used to fix the internal thread block 140. The threaded column 150 can be screwed into the internal thread block 140 of the other set of accessory bodies 100 to axially fasten the two sets of accessory bodies 100. Several multi-segment sealing blocks 160 can form a sealing structure by making close contact with the cable connection ends.

[0020] The auxiliary mechanism 200 includes a transmission assembly 210 for transmitting rotational power when tightening the internal thread block 140, and a clamp assembly 220 that can drive a plurality of sealing blocks 160 to contact the cable connection end as the transmission assembly 210 rotates; the transmission assembly 210 is located outside the mounting plate 120, and the clamp assembly 220 is located between the mounting plate 120 and the sealing blocks 160.

[0021] Specifically, the accessory body 100 is provided with two sets, and the two sets of connecting pipes 110 are respectively sleeved at the connection points of the two cables.

[0022] Furthermore, the transmission assembly 210 includes a toothed post 211 fixedly connected to the outer end face of the threaded post 150, a gear 212 meshing with the outer surface of one of the toothed posts 211, and a gear disc 213 meshing with the other side of the gear 212.

[0023] Preferably, the transmission assembly 210 also includes a through groove 214 formed on the outer surface of the mounting plate 120, a limiting ring 215 fixedly connected to the inner wall of the mounting plate 120 and used in conjunction with the gear 213, and a support 216 fixedly connected to the inner surface of the gear 212.

[0024] It should be noted that when the teeth of the toothed column 211 and the gear 212 are aligned and the toothed column 211 is rotated, the threaded column 150 is tightened while the gear 212 is rotated synchronously. The gear 212 then drives the gear disk 213 to rotate around the limiting ring 215. The through groove 214 is used to provide rotation space for the gear 212, thereby eliminating structural interference between the gear 212 and the mounting disk 120 and ensuring smooth transmission of rotational power.

[0025] Support column 216: Fixed to the inner surface of gear 212, and connected to mounting plate 120 at the bottom through bearing seat, providing rotational support for gear 212, reducing frictional resistance when gear rotates, and improving power transmission efficiency.

[0026] It should be noted that the gear disc 213 is rotatably sleeved on the outer surface of the limiting ring 215, and a rotating bearing seat is installed at the connection between the support column 216 and the mounting plate 120. When the rotating gear 211 is rotated, the threaded column 150 can be screwed into the corresponding internal threaded block 140 of another set of accessory bodies 100 through the corresponding internal threaded block 140, thereby fixing the two sets of accessory bodies 100 together. At this time, the gear 212 is driven to rotate by one set of gear 211, and then the gear 212 drives the gear disk 213 to rotate around the limiting ring 215.

[0027] Furthermore, the clamp assembly 220 includes several arc grooves 221 formed on the outer surface of the gear disc 213, force-bearing blocks 222 movably connected to the inner wall of the arc grooves 221, and connecting rods 223 fixedly mounted on the outer surface of the force-bearing blocks 222 by bearings and used to fix the sealing block 160.

[0028] Specifically, the clamp assembly 220 also includes a positioning block 224 fixedly connected to the outer surface of the connecting rod 223, and a positioning groove 225 opened on the outer surface of the fixing plate 130 and used in conjunction with the positioning block 224.

[0029] It should also be noted that the inner wall of the arc groove 221 is arc-shaped and the radial depth gradually changes. When the toothed disc 213 rotates, it can squeeze the force block 222 through the inclined inner wall of the arc groove 221, forcing the force block 222 to move radially closer to the center of the cable. Then, the force block 222 drives the connecting rod 223 and the sealing block 160 to move synchronously. At the same time, the positioning block 224 and the connecting rod 223 slide along the inner wall of the positioning groove 225 under the drive of the force block 222, thereby driving the sealing block 160 to make tight contact with the connection end of the cable. Through the sliding cooperation between the positioning block 224 and the positioning groove 225, it can be ensured that the connecting rod 223 only moves radially in the direction close to or away from the cable, avoiding deviation that would cause uneven adhesion of the sealing block 160.

[0030] Preferably, the number of arc grooves 221, force-bearing blocks 222 and connecting rods 223 all correspond to the number of sealing blocks 160. The outer surface of the positioning block 224 slides in contact with the inner wall of the positioning groove 225. Multiple sealing blocks 160 can be disassembled and replaced from the surface of the corresponding connecting rod 223. When the gear plate 213 rotates, it can apply pressure to the force block 222 through the inner wall structure of the arc groove 221, thereby causing the force block 222 to drive the connecting rod 223 and the positioning block 224 to slide along the inner wall of the positioning groove 225, and finally drive the sealing block 160 to contact the connection end of the cable through the connecting rod 223.

[0031] When using, Two sets of connecting pipes 110 are respectively fitted onto the connection points of the two cables to be connected, ensuring that the connection ends of the two cables are fully aligned. At this time, several sealing blocks 160 are in a relaxed state away from the cables. Next, the teeth of the toothed column 211 and the gear 212 are accurately aligned. Then, the toothed column 211 is rotated to drive the threaded column 150 to rotate synchronously, so that the threaded column 150 is slowly screwed into the internal threaded block 140 of another set of accessory bodies 100 through the corresponding internal threaded block 140. In this way, the two sets of accessory bodies 100 gradually move axially closer along the connection end of the cable through the fixed plate 130. At the same time, the gear 212 is driven to rotate synchronously by the gear column 211, and then the gear 212 drives the gear disk 213 to rotate around the safety limit ring 215. At this time, the through groove 214 avoids structural interference between the gear 212 and the mounting disk 120. During this process, the toothed disc 213 applies radial pressure to the force-bearing block 222 through the inclined and gradual structure of the inner wall of the arc groove 221, forcing the force-bearing block 222 to move towards the center of the cable. Then, the force-bearing block 222 drives the connecting rod 223 and the sealing block 160 to move synchronously. At the same time, the positioning block 224 restricts the connecting rod 223 and the sealing block 160 to move only along the inner wall of the positioning groove 225, so as to prevent the sealing block 160 from shifting and causing uneven sealing. Ultimately, multiple sealing blocks 160 simultaneously make tight contact with the cable connection end, forming a reliable multi-segment sealing structure; During later maintenance: If a single sealing block 160 ages or is damaged, it can be replaced directly from the surface of the corresponding connecting rod 223 after the threaded post 150 is loosened to drive each component to reset. This eliminates the need to disassemble the entire structure, thus significantly reducing maintenance difficulty and cost.

[0032] In summary, by setting up the auxiliary mechanism 200, not only can multiple sealing blocks 160 be automatically controlled to make tight contact with the cable connection end when the rotating gear 211 drives the two sets of accessory bodies 100 to approach, but also when a single sealing block 160 is damaged, it can be disassembled and replaced independently, so as to significantly reduce the maintenance workload and cost while ensuring the sealing performance of the accessory body 100.

[0033] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
