Adjustable cable bridge

Abstract

The invention provides an adjustable cable bridge, and belongs to the technical field of power cable bridges, the adjustable cable bridge comprises a bridge body and an upper cover, the bridge body comprises a bottom plate and side plates arranged on the two sides of the bottom plate, the upper cover is buckled at the upper ends of the side plates, and the bottom plate is a telescopic bottom plate; the upper cover is a telescopic cover plate; a turnbuckle bolt part is arranged between the two side plates, the turnbuckle bolt part comprises a first lead screw, a turnbuckle nut and a second lead screw, one end of the first lead screw is fixedly connected with the side plate on one side, one end of the second lead screw is connected with the side plate on the other side through a bearing, the second lead screw extends to the outer side of the side plate, and the turnbuckle nut is connected with the first lead screw. The outer side of the second lead screw is connected with a rocker arm. The bottom plate and the upper cover in the device adopt telescopic mechanisms, and cable bridge grooves of different sizes can be adjusted according to needs to achieve effective matching. The cable fixing bridge is flexible in structure, and the defect that a traditional cable fixing bridge cannot be adjusted according to the cable capacity of the bridge is overcome.

Description

technical field [0001] The invention belongs to the technical field of power cable bridges, and in particular relates to an adjustable cable bridge. Background technique [0002] As a common support and protection device for cable laying in the electrical equipment power supply system, the cable tray protects and guides the cables laid in the cable tray. Traditional cable trays are mainly divided into trough, ladder, tray and grid structures. At present, it is common to add a cover plate to the main body of the bridge frame, and the connection mode between the cover plate and the main body of the bridge frame is connected by bolts. Since the current design of bridges mostly adopts the concept of integrated bridges, various cable systems such as power cables, communication cables, and fire cables share one bridge, and the cables in the cable bridge are intricate and complicated, which brings inconvenience to maintenance personnel. In addition, most of the commonly used cabl...

Since the current design of bridges mostly adopts the concept of integrated bridges, various cable systems such as power cables, communication cables, and fire cables share one bridge, and the cables in the cable bridge are intricate and complicated, which brings inconvenience to maintenance personnel.

In addition, the commonly used cable trays are mostly fixed bridges, which cannot meet the growing demand for cable systems, and the construction of cable tray expansion projects is difficult
