Embodiment Construction

[0021] In order to better understand the technical content of the present invention, specific examples are given and described as follows in conjunction with the accompanying drawings.

[0022] As shown in the figure above, the high-speed railway tunnel leakage cable fixing jig consists of a base 1 , a cover plate 2 , a rotating shaft 4 and a hook 10 . The cover plate and the base are connected by a rotating shaft one 51 and a rotating shaft two 52, a positioning spring 7 and a rotating shaft 6 are arranged in the hook, and a safety device 9 is arranged on the buckle plate 8 .

[0023] Among them, the base 1 is used to place the leakage cable; the pinch plate 8 cooperates with the cover plate 1 31 and the cover plate 2 32 to fix the cable; the positioning spring 7 keeps the pinch plate 8 in a buckled state, and the safety device passes through the Cooperate with the positioning block to prevent the clamp from being accidentally opened due to non-human factors.

Abstract

The invention provides a novel fixture capable of being used for fixing a leaky cable in a high-speed railway tunnel, comprising a base, a rotating shaft, a cover plate, a hook and the like. When in use, the fixture is fixed on the tunnel wall surface through bolts and hexagonal screw studs, the leakage cable is put into the cover plate of the rear cover in the fixture base, the hook and loop safety is opened, and the fixation of the leakage cable is completed. By designing a novel leakage cable fixture, the invention can bear the impact load of the piston wind generated by the train with higher running speed in the tunnel, the unique hook-and-loop structure can prevent the cable from falling off in the use process, and the anchoring engagement structure can solve the problem of the existing fixture following the whole rotation in use, and has higher safety and reliability.

Description

technical field [0001] The invention belongs to the field of mechanical engineering, and in particular relates to a fixture for fixing leaking cables in high-speed railway tunnels. Background technique [0002] Leaky cables are important equipment in high-speed railway systems and the best way for high-speed railways to communicate in tunnels, and fixing fixtures are the only solution to fix leaky cables in high-speed railway tunnels. However, with the continuous improvement of train operating speed, the piston wind impact generated when the train is running in the tunnel is also more severe, and the existing fixture structure will no longer be applicable. At present, the leaking cable fixing fixtures reserved by various domestic companies are only used for operating speeds of 350 kilometers and below, and there is no supporting fixture technical solution related to speed increase, so it is necessary to reserve such technical solutions in advance. And in actual engineering,...
