Description
Technical field
The utility model relates to a kind of bridge device, especially a kind of bridge device being applicable to laying cable.
Background technology
What the outdoor laid of temporary engineering cable adopted originally is that direct buried formula is laid, but consider that direct buried formula cabling road pavement failure mechanics is larger, and operating safety factor is low, operation maintenance is inconvenient, rush to repair excessive cycle after fault and very large loss is caused to production, and when the direct buried formula of cable lays circumstance complication, difficulty of construction is also larger.
Utility model content
Utility model object: a kind of outdoor laid device being applicable to temporary engineering cable is provided, and require that the operating safety factor of this device is high, operation maintenance convenient.
Technical scheme: laying cable bridge device described in the utility model, comprises at least two crane span structure assemblies and is connected to the connector between adjacent two crane span structure assemblies; The bracing frame that crane span structure assembly comprises top cover, wire casing and is supported in below wire casing; The wire casing of adjacent two crane span structure assemblies by connector abutting joint, and is connected with jumper between two wire casings; Top cover covers on the notch of wire casing, and the chimb on the forward edge place of top cover is provided with for snapping into another top cover posterior edges.
Adopt crane span structure assembly and connector to form bridge structure, avoid adopting direct burial, effectively can reduce the difficulty of construction, and operation maintenance is also more convenient; Adopt jumper to be electrically connected by each crane span structure assembly, and be finally connected with ground connection main line, after avoiding long term outdoor to use, the electric connecting point of each crane span structure assembly gets rusty and disconnects, and effectively improves the safety in utilization of each crane span structure assembly; Adopt chimb can prevent the joint of adjacent two top covers from leaking in wire casing, further increase the safety in utilization of each crane span structure assembly.
As further improvement of the utility model scheme, between wire casing and bracing frame, be provided with electro-insulating rubber pad.Adopt electro-insulating rubber pad by wire casing and bracing frame electrical isolation, the safety in utilization of each crane span structure assembly can be further increased.
As further restriction scheme of the present utility model, the section of top cover is herringbone, and is provided with in the below of top cover the positive stop strip be embedded in wire casing.Adopt lambdoid top cover can prevent top cover any standing water on top from getting rusty, extend the useful life of top cover, positive stop strip can prevent the relative wire casing double swerve of top cover simultaneously.
As further restriction scheme of the present utility model, the left and right edges of top cover tilts to extend downward the top of connector and jumper.The left and right edges of top cover is extended to the top of connector and jumper, rainproof protection can be carried out to connector and jumper, prevent connector and jumper from getting rusty, increase the service life.
Compared with prior art, its beneficial effect is the utility model: (1) adopts crane span structure assembly and connector to form bridge structure, avoids adopting direct burial, effectively can reduce the difficulty of construction, and operation maintenance is also more convenient; (2) adopt jumper to be electrically connected by each crane span structure assembly, and be finally connected with ground connection main line, after avoiding long term outdoor to use, the electric connecting point of each crane span structure assembly gets rusty and disconnects, and effectively improves the safety in utilization of each crane span structure assembly; (3) adopt chimb can prevent the joint of adjacent two top covers from leaking in wire casing, further increase the safety in utilization of each crane span structure assembly.
