Description

Technical Field

[0001] This utility model relates to the field of protective cover technology, and in particular to a rhomboid hazardous space protective cover. Background Technology

[0002] A turnout is a track connection device that allows trains to switch from one track to another. It is used to achieve train turning, cross-track operation, and other requirements in areas where two or more tracks intersect or run parallel. Turnouts connect tracks in different directions via switch rails, frogs, and other components. When two tracks intersect at a certain angle, a diamond-shaped gap is formed, known as a "diamond space." At a turnout, iron pads are laid under the rails on both sides, and these pads are energized. One pad under one rail is connected to a positive power source, and the other pad under the other rail is connected to a negative power source. During train operation, if a foreign object intrudes into the track, it may accidentally come into contact with the energized iron pads on both sides. This can instantly create a current path in the iron pads under the rails, interfering with the normal operation of the track circuit and even threatening train safety. Utility Model Content

[0003] The technical problem to be solved by this utility model is: in order to solve the problem that when foreign objects intrude into the track of existing turnouts, the foreign objects will accidentally come into contact with the electrified iron pads on both sides, and the iron pads under the rails on both sides will instantly conduct the circuit and form a current path, causing interference with the normal operation of the track circuit and even threatening the safety of train operation, a diamond-shaped hazardous space protection cover is provided.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a diamond-shaped hazardous space protective cover, including a protective cover body installed between two rails. The protective cover body has a downward-facing slot, which extends axially through both ends of the protective cover body. A partition is provided inside the slot, dividing the slot into two mutually separated slots: a first slot and a second slot. The first slot is used to cover the iron pad of one side of the rail, and the second slot is used to cover the iron pad of the other side of the rail. Compared with the prior art, this solution, by installing the protective cover body between the two rails of the turnout, with the first slot below the protective cover body covering the iron pad of one side of the rail and the second slot covering the iron pad of the other side of the rail, separates the two iron pads, thus preventing foreign objects from contacting and conducting between the two iron pads and causing traffic risks, and ensuring traffic safety.

[0005] Because there is a certain gap between the two iron pads, in order to ensure the reliability of electrical isolation and better separate the iron pads on both sides, in some preferred embodiments, the partition protrudes from the bottom surface of the protective cover body. The partition protruding from the bottom surface of the protective cover body ensures that there is no gap at the bottom of the protective cover body during installation, preventing foreign objects from getting stuck in the gap and causing electrical conductivity between the two iron pads.

[0006] To facilitate the installation of the protective cover body, in some preferred embodiments, the protective cover body is equipped with a fixing mechanism for fixing it between the rails.

[0007] To achieve the fixing mechanism, in some preferred embodiments, the fixing mechanism includes a through hole formed on the protective cover body, the through hole extending from the top of the protective cover body to a slot below.

[0008] In some preferred embodiments, there are two through holes with both ends located on both sides of the protective cover body.

[0009] Given that the diamond-shaped spaces between the rails result in varying installation space dimensions for the protective cover, to ensure that the installation of the protective cover is not affected by these spatial differences, in some preferred embodiments, the protective cover body has a retractable telescopic section located within the first or second groove. The length of the protective cover body can be adjusted via the telescopic section to accommodate installations in different diamond-shaped spaces, improving the applicability of the protective cover body. In complex and variable track environments, it maintains a tight cover over the iron pad, effectively preventing the intrusion of foreign objects and eliminating the risk of abnormal circuit continuity due to accidental overlap, thus comprehensively ensuring train operation safety.

[0010] In order to realize the telescopic section on the protective cover body, in some preferred embodiments, the cross section of the telescopic section is composed of several groups of first protruding sections and first groove sections arranged alternately along the axial direction of the protective cover body.

[0011] In some preferred embodiments, the material of the protective cover body is rubber.

[0012] The beneficial effects of this utility model are as follows: When the diamond-shaped hazardous space protective cover of this utility model is in use, by installing the protective cover body between the two rails of the turnout, the first groove cover under the protective cover body is set on the iron pad plate of one side of the rail, and the second groove cover is set on the iron pad plate of the other side of the rail, thus separating the iron pad plates on both sides. This prevents foreign objects from contacting the iron pad plates on both sides and conducting electricity, which could cause traffic risks and ensure traffic safety. It also avoids the problem in existing turnouts where, when foreign objects invade the track, they may accidentally come into contact with the electrified iron pad plates on both sides, causing the iron pad plates under the rails on both sides to instantly conduct electricity and form a current path, which could interfere with the normal operation of the track circuit and even threaten traffic safety.
