Description

Technical Field

[0001] The utility model relates to the technical field of railways, in particular to a liquid replenishing device for a detection wheel of a large rail flaw detector vehicle. Background Art

[0002] Today, with the continuous increase in railway speed, high-speed railways are becoming increasingly popular, and damages of high-speed railways are gradually emerging. The requirements for the flaw detection system of railway "doctors" are also getting higher and higher, demanding continuous improvement in the flaw detection rate and detection speed of rail flaw detection. High-speed rail flaw detection has difficulties such as long sections, few entrances and exits, night flaw detection, and less block time. The traditional flaw detector operation mode cannot overcome these difficulties, while the large rail flaw detector vehicle stands out with its flaw detection speed and flaw detection coherence far exceeding other flaw detection means, becoming the mainstay of the high-speed rail flaw detection system.

[0003] The detection wheel of a large rail flaw detector vehicle is an important part of the flaw detection system. The pressure inside the wheel needs to be maintained at a specific pressure, but during the use and storage of the detection wheel, the problem of pressure drop will inevitably occur. The traditional liquid storage tank is a steel structure tank. The liquid replenishing method is to add 2 / 3 of the detection wheel liquid, then inflate and pressurize, and then replenish the detection wheel with liquid. Due to its steel structure tank body, the situation inside the tank is invisible, and it is impossible to know the remaining amount of the detection wheel liquid inside, which easily causes gas to be injected into the detection wheel and frequent liquid addition operations inside the tank; at the same time, the steel structure makes the whole too heavy; due to the method of inflating and pressurizing, the liquid replenishment becomes very inconvenient, requiring the use of special tools to open the upper cover, then add the detection wheel liquid, and then lock and inflate and pressurize. When replenishing liquid under the vehicle, since the switch is on the tank body, the liquid replenishment can only be operated nearby or by two people at a long distance, which is inconvenient to operate.

[0004] Therefore, a liquid replenishing device for a detection wheel with excellent performance and low cost needs to be studied urgently. Content of the Utility Model

[0005] In view of this, in order to solve the problems in the technical background, the utility model provides a liquid replenishing device for a detection wheel of a large rail flaw detector vehicle, and the specific technical solution is as follows:

[0006] A liquid replenishing device for a detection wheel of a large rail flaw detector vehicle includes a spray bottle body, a lid arranged above the spray bottle body, and a PU tube connected to a nozzle on the lid. A manual switch, a one-way valve, and a liquid replenishing nozzle are arranged on the PU tube. The liquid replenishing nozzle is arranged at one end of the PU tube. One end of the PU tube is connected to the detection wheel through the liquid replenishing nozzle. A manual switch and a one-way valve are arranged on the PU tube near the liquid replenishing nozzle.

[0007] Furthermore, a liquid filling port, a power switch, and an indicator light are arranged on the lid.

[0008] Further, the spray bottle body is made of transparent plastic material, which is convenient for observing the remaining liquid volume inside the spray bottle body.
