Abstract
The utility model discloses a cable bracket system for a cable trench or a tunnel. The cable bracket system at least comprises a cable bracket which is arranged in the cable trench or the tunnel and is provided with a guide rail groove, wherein an L-shaped drawer-type fire-resistant clapboard which can be moved freely or limited and fixed is arranged in the guide rail groove in the cable bracket; an abrasion-resistant material layer or a rail sliding mechanism and a limiting mechanism are arranged on the contact part between the bottom of the L-shaped drawer-type fire-resistant clapboard and the guide rail groove on the cable bracket; cable brackets are integrated modularized finished brackets and can be connected with each other side by side; a plurality of cable binding holes which are formed in a row are formed in the cable bracket; and the drawer-type fire-resistant clapboard has a modularized structure and is matched with the guide rail groove on the cable bracket. The cable bracket system is neat and attractive after being installed; field cutting and roughness and spines generated by welding do not exist; and the cable bracket is attractive and cannot damage the shuck of a cable, is favorable for safe operation of the cable, and has the characteristics of simple construction, convenience in operation and maintenance, neat and attractive appearance and the like.
Description
Technical field
The utility model relates to the cable bearer system in a kind of cable channel or tunnel, is applicable to the particularly isolation of laying and prevent fires of intelligent substation cable channel or tunnel inner cable, optical cable of electric substation.
Background technique
Cable, optical cables a large amount of in the electric substation lay through cable channel or cable tunnel inner support mode.This system of laying is convenient to construction, maintenance and the maintenance of cable, and construction, operating experience are enriched, and are widely used.
Shown in Figure 1 is a kind of common cable ditch cable laying sectional view, and it is that cable bearer 12 is installed in cable channel 11.For guaranteeing cable running safety, cable laying is installed also need satisfy ask for something.Such as, for satisfying reliability of operation, to fire-fighting; Report to the police emergency lighting, breaker operator DC electrical source and computer monitoring; Dualization relay protection, the cable of dualization such as emergency power supply need be prevented fires from isolating and laid, or protective refractory is carried out in one of them loop; When power cable and actuating cable or communication cable laying are in same cable channel or cable tunnel, should adopt fire prevention groove box or fire bulkhead to separate.Same loop works power supply and standby power supply cable should be arranged in the different support layer.Deng.
Therefore, often fire bulkhead 13 need be set in the cable channel, perhaps lay fire prevention groove box 14.As shown in Figure 2, this figure lays signal for the cable channel fire resisting division.
Below existing, conventional design, construction be badly in need of improved problem:
(1) in the actual engineering construction process, fire bulkhead whole often (different size) is transported to the electric substation scene, and the workmen cuts according to on-site actual situations, the crude irregularity in edge.
(2) punch and use Steel Wire Lashing in the scene of adopting, and supports loose have even bending deflection, and the jointing slit is obvious.
(3) since fire bulkhead do not have can be for convenience detach annex or measure, at present general installation complex is dismantled the manpower and materials that need labor with a large amount of side direction fire bulkheads in extension project.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that existing technology exists; And provide a kind of employing modular design, batch production to process theory; Only change original and lay the simple thinking that horizontal fire bulkhead and vertical fire bulkhead realization fire resisting division are set on the basis; Cable channel inner support and fire bulkhead are designed to the cable bearer system in the cable channel or the tunnel of integration product, make that construction is simple, operating maintenance is convenient, profile is neat and artistic.
The purpose of the utility model is accomplished through following technological scheme; Which comprises at least be installed in cable channel or the tunnel, the cable bearer of band guide rail groove, dispose in the guide rail groove on this cable bearer and can move freely or spacing fixing L shaped drawer type fire bulkhead.
The bottom of said L shaped drawer type fire bulkhead and the guide rail groove contact position on the cable bearer are lined with wear-resistant material layer or are provided with slide mechanism and position-limit mechanism.
Described cable bearer is integral type modularization finished product support and can joins side by side each other, in said cable bearer, offers a plurality of cable tie holes that are an arranged; Described drawer type fire bulkhead adopt modular construction and with said cable bearer on the guide rail groove layout that matches.
The beneficial effect of the utility model is:
(1) cable bearer and fire bulkhead all become the batch production product, have avoided conventional on-site cutting and welded and installed, have simplified the work on the spot amount, have improved efficiency of construction;
(2) this drawer type fire bulkhead and cable bearer system make that the enlarging of cable laying engineering is convenient, needn't remove fire bulkhead earlier and restore installation again, only need successively fire bulkhead to be extracted out, shut " drawer " more successively after cable to be extended is put into and get final product;
(3) this drawer type fire bulkhead and cable bearer system conversion are convenient.No matter be that support or drawer type fire bulkhead modular unit all can independent dismounting and replacings;
(4) it is neat and artistic that the back is installed by this drawer type fire bulkhead and cable bearer system.Industrialized product, the crude and spine of no on-site cutting and welding generation, not only attractive in appearance but also can not damage cable sheath, help cable running safety.

Embodiment
To combine below accompanying drawing to the utility model make detailed introduction: Fig. 3, shown in 4; The cable bearer system in described cable channel of the utility model or tunnel; Which comprises at least be installed in cable channel 21 or the tunnel, the cable bearer 23 of band guide rail groove 22, dispose in the guide rail groove 22 on this cable bearer 23 and can move freely or spacing fixing L shaped drawer type fire bulkhead 24.
Described cable bearer 23 offers a plurality of cable tie holes 25 that are an arranged for integral type modularization finished product support also can join each other side by side in said cable bearer 23; Described drawer type fire bulkhead 24 adopt modular constructions and with said cable bearer 23 on guide rail groove 22 layout that matches.
Embodiment
At first design L shaped drawer type fire bulkhead 24; According to cable bearer 23 horizontal width (w value) that horizontal span (being generally 800mm) is confirmed drawer type fire bulkhead 24 is installed; According to the vertical span of cable bearer 23 cantilevers (be generally 150～250mm) confirm drawer type fire bulkhead 24 height (h value); Can adopt inorganic fireproof material or organic fire prevention material, in the time can satisfying fire protection requirement, also can adopt and be coated with fireproof paint or other novel fire proofing materials outside the metallic material.
Secondly the cable bearer 23 of guide rail groove 22 is with in design, and cantilever quantity as required (general 2～5) can be designed to integrated pectination support, perhaps free-standing single cantilever support.Support is installed on cable channel 21 sidewalls through EXPANSION ANCHOR BOLTS.For avoiding excessive alignment error, relatively recommend to be designed to integrated pectination support.Guide rail groove 22 is set on the support cantilever.Can be provided with in the guide rail groove 22 and roll or slide guide, also oiling agent such as coating butter is only released to make things convenient for drawer type fire bulkhead 24 to advance.Also limited bayonet can be set in groove simultaneously.
