Fireproof high-speed leaky cable clamp

Abstract

The invention relates to a fireproof high-speed leaky cable clamp which comprises a base, a left clamp, a right clamp and a middle clamp, the middle clamp comprises a supporting seat, a pressing buckle, a bolt, a nut, an expansion anchor nail, a fixing column and a screw, one end of the pressing buckle is rotatably connected with one end of the supporting seat, and the other end of the pressing buckle and the other end of the supporting seat are each provided with a semicircular plate. The two semicircular plates are matched up and down, fixing holes are formed in the middles of the two semicircular plates respectively, and after a bolt penetrates through the two fixing holes, the two semicircular plates are locked by screwing a nut on the bolt; and the middle clamp is made of stainless steel materials. The clamp has the advantages that three clamps are designed into a group, the left auxiliary clamp and the right auxiliary clamp are arranged, the middle clamp is stainless steel metal, and the structural design can meet the requirements of tunnels where bullet trains / high-speed rails pass through, and the current market requirements are met. The left clamp, the right clamp and the base are made of fireproof nylon 66, so that the fixture has a fireproof function, and the middle fixture is made of stainless steel and also has a fireproof function.

Description

technical field [0001] The invention relates to the technical field of leaky cable clamps, in particular to a fireproof high-speed leaky cable clamp. Background technique [0002] Leaky cable is the abbreviation of leaky coaxial cable (Leaky Coaxial Cable), usually referred to as leaky cable or leaky cable. Its structure is basically the same as that of ordinary coaxial cable. The conductor consists of three parts. In the traditional subway line tunnel engineering, the leaky cable installation fixture is directly nailed to the wall of the civil structure through the internal expansion bolt. Due to the environment in the tunnel, when a car passes by, the wind and vibration will cause damage to the leaky cable fixture; currently In order to fix the leaky cable well, the leaky cable fixture is also constantly changing, but as the speed of the bullet train / high-speed rail increases, the speed when passing through the tunnel can reach 350 kilometers per hour. The previous design...

Problems solved by technology

In traditional subway line tunnel engineering, the leaky cable installation fixture is directly nailed to the wall of the civil structure through the internal expansion bolt. Due to the environment in the tunnel, when a car passes by, the wind and vibration will cause damage to the leaky cable fixture; currently In order to fix the leaky cable well, the leaky cable fixture is also constantly changing, but as the speed of the bullet train / high-speed rail increases, the speed when passing through the tunnel can reach 350 kilometers per hour. The previous design requirements of the leaky cable fixture can only Satisfy the application below 200 kilometers per hour. Once the speed exceeds this speed, problems such as vibration and fracture will occur, which cannot meet the use of higher speeds
