Abstract

The invention discloses a wheel sensor comprising a base, a transmitting terminal casing, a receiving terminal casing, a transmitting terminal coil and a receiving terminal coil. The transmitting terminal casing and the receiving terminal casing are respectively fixedly mounted on the base. The transmitting terminal coil is mounted in the transmitting terminal casing, and the receiving terminal coil is mounted in the receiving terminal coil. The transmitting terminal coil is wound on a transmitting terminal winding reel that is arranged in a transmitting terminal support, and the transmitting terminal support is arranged in a transmitting terminal sleeve mounted in the transmitting terminal casing. The receiving terminal coil is wound on a receiving terminal winding reel that is arranged in a receiving terminal support, and the receiving terminal support is arranged in a receiving terminal sleeve mounted in the receiving terminal casing. By the special supporting structure design, the coils are fixed in the casings, and therefore, deviation of the coils in packaging is overcome and percent of pass of products is guaranteed.

Description

technical field [0001] The invention discloses a railway detection device, in particular to a wheel sensor. Background technique [0002] As the most effective device for detecting whether there is a train in the rail section in the current technology, the wheel sensor is widely used in railway transportation. When the wheel sensor is in use, it is usually installed on the rail track, and it is installed every 1.3 kilometers. The wheel sensor detects the number of train wheels passing by, so as to count the number of trains in the rail section, and then judge whether there is a train in the section. The wheel sensor in the prior art usually includes a transmitting end and a receiving end, both of which are realized by coils. The conventional technology is to wind the coils on the bobbins, and then wrap the windings through the sealing process. The frame is fixed together with the coil in the casing, and the coil is likely to be skewed during the sealing process, the...
