BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a schematic diagram of the overall three-dimensional structure of a protective cover of a magnetic-electric induction sensor for a railway crossing according to the utility model;

[0014] In the figure: wrapping structure 1; square through hole 2; inclined structure 3; mounting structure 4. DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Example

[0016] This embodiment discloses a railway crossing magnetoelectric induction sensor protective cover, combined with Figure 1 As shown, a protective cover for a magneto-electric induction sensor at a railway crossing comprises a wrapping structure 1, wherein the wrapping structure 1 is connected to a mounting structure 4 via an inclined structure 3, wherein the wrapping structure 1, the inclined structure 3 and the mounting structure 4 are integrally formed or connected by welding, and since the magneto-electric crossing sensor needs to be installed at the lower end of the outer side of a rail between two railway sleepers during installation, the protective cover needs to span across two sleepers, and a square through hole 2 is provided on the wrapping structure 1, wherein a plurality of the square through holes 2 are provided, and the plurality of square through holes 2 are evenly distributed on the wrapping structure 1, and the square through holes 2 can be used to facilitate the train wheels to cut the magnetic flux lines of the crossing sensor, thereby generating an alarm and ensuring the alarm effect.

[0017] The tilting angle of the tilting structure 3 is 45 degrees. The tilting of the tilting structure 3 can facilitate the crossing of loading and unloading machinery and motor vehicles. At the same time, the tilting of the tilting structure 3 forms a local triangle. The principle of the stability of the triangle can be used to improve the strength of the device.

[0018] The mounting structure 4 is provided with circular holes, which are through holes. The number of the circular holes is not less than two. The circular holes can be used to facilitate fixing the protective cover to the sleepers using railway spikes, thereby achieving fixation of the protective cover.

[0019] The wrapping structure 1, the inclined structure 3 and the mounting structure 4 are made of steel, and an anti-rust coating is arranged on the surface thereof. The overall thickness of the wrapping structure 1, the inclined structure 3 and the mounting structure 4 is not less than 2 mm. Since the wrapping structure 1, the inclined structure 3 and the mounting structure 4 are made of steel, the strength of the wrapping structure 1, the inclined structure 3 and the mounting structure 4 is guaranteed, and the protective cover is prevented from being crushed by motor vehicles and loading machinery to cause collapse, deformation and other damages, thereby improving its service life. By arranging an anti-rust layer on its surface, it is possible to prevent the device from rusting and being damaged in a humid environment, thereby reducing its service life. The steel has the following advantages: 1. High strength, plasticity, heat resistance and toughness; 2. Uniform material and high working reliability; 3. The steel structure is easy to manufacture, with a short construction period and good assembly performance; 4. The steel is weldable; 5. The steel is leak-proof, which is convenient for making into a closed structure; 6. The steel is closer to being a homogeneous and isotropic body.

[0020] In order to improve the strength of the device, the wrapping structure 1 is supported by an I-beam, and the I-beam support is fixed in the wrapping structure 1 by welding. Since the wrapping structure 1 is a hollow structure, the I-beam arranged inside the wrapping structure 1 can effectively support the wrapping structure 1, thereby improving the compressive strength of the wrapping structure 1, avoiding damage such as collapse and deformation of the wrapping structure 1 caused by the rolling of motor vehicles and loading machinery, and improving its service life.

[0021] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
