Problems solved by technology

[0003] There are many kinds of materials for cable trays, and fiberglass is one of them. When installing cable trays outdoors, a cover plate is usually installed on the top of the cable tray. The cover plate is used to prevent direct sunlight on the cables and reduce the outdoor environment. For the impact on the cable, install the cable tray indoors, and use the cover to block the accumulation of dust and the interference of other liquids. Therefore, the cover is more important for the cable tray. If the cover is detached from the cable tray, it will have a greater impact on the cable. The cover plate and the cable tray are fastened together. Although the existing fastening device can play a fastening role, the fastening effect is not good, and the disassembly and assembly are cumbersome

Abstract

The invention discloses a glass fiber reinforced plastic cable bridge and a cover plate fastening device thereof. The fastening device comprises a sleeve, one end of the sleeve is fixedly connected with a first sealing plate, the first sealing plate is fixedly connected with a rubber pad, the rubber pad makes contact with the cable bridge, and the top of the cable bridge is provided with a cover plate; a second sealing plate is fixedly connected to the end, away from the first sealing plate, of the sleeve; a movable opening is formed in one side of the sleeve; a movable block is arranged at the position, close to the movable opening, in the sleeve; a fixed block is fixedly connected to the middle of the movable block; a moving block is arranged on the side, close to the fixed block, of themovable block; one side of the movable block is in threaded connection with a first screw rod, one end of the first screw rod is connected with the first sealing plate through a first movable mechanism, the other end of the first screw rod penetrates through the second sealing plate, and a pushing block is arranged on the side, away from the movable opening, in the sleeve. The cable bridge has the beneficial effect that the cover plate can be fastened on the cable bridge.

Description

technical field [0001] The invention relates to the technical field of cable bridges, in particular to a fastening device for a fiberglass cable bridge and its cover. Background technique [0002] Cable trays are divided into trough type, tray type, ladder type, grid type and other structures, and are composed of brackets, supporting arms and installation accessories. The bridge frame in the building can be erected independently, or attached to various buildings (structures) and pipe gallery supports. [0003] There are many kinds of materials for cable trays, and fiberglass is one of them. When installing cable trays outdoors, a cover plate is usually installed on the top of the cable tray. The cover plate is used to prevent direct sunlight on the cables and reduce the outdoor environment. For the impact on the cable, install the cable tray indoors, and use the cover to block the accumulation of dust and the interference of other liquids. Therefore, the cover is more impor...
