Wireless data acquisition device and steel rail milling cutter equipment provided with same

Abstract

The invention discloses a wireless data acquisition device which is applied to a steel rail milling cutter. The wireless data acquisition device comprises a data acquisition module and a wireless transmission module, wherein the data acquisition module is arranged on the steel rail milling cutter, and comprises a sensor, a battery and a wireless charging receiver; the sensor is used for acquiringvibration data; the battery is used for supplying power; the wireless charging receiver is used for receiving electric energy to supply power to the battery; the wireless transmission module is adjacent to the data acquisition module, and comprises a wireless data receiver and a wireless charging sender; the wireless data receiver is used for receiving the vibration data; and the wireless chargingsender is connected to an external power supply for sending the electric energy to the wireless charging receiver. Steel rail milling cutter equipment is used for milling a steel rail, and comprisesthe steel rail milling cutter, a control system and the wireless data acquisition device, and the wireless data acquisition device acquires and transmits the vibration data of the steel rail milling cutter to the control system to judge the state of the steel rail milling cutter.

Description

technical field [0001] The present application relates to a wireless data acquisition device for collecting vibration data of a rail milling cutter and a rail milling cutter device equipped with the device. Background technique [0002] With the advancement of track maintenance technology (especially rail milling technology), rail milling has been widely used. As the core component, the rail milling cutter used for rail milling directly undertakes all milling work. During the milling process of the milling cutter, as the amount of wear increases, the milling effect is greatly weakened, and the milling process is usually prone to edge chipping and other conditions. For the identification and judgment of the above situations, at present, manual inspection is mainly used in the work gap. However, the milling cutter may have been abnormal (such as chipping) during the operation, which makes the operation after the milling cutter abnormal is invalid. At the same time, manual Th...

Problems solved by technology

During the milling process of the milling cutter, as the amount of wear increases, the milling effect is greatly weakened, and the milling process is usually prone to edge chipping and other conditions

For the identification and judgment of the above situations, at present, manual inspection is mainly used in the work gap. However, the milling cutter may have been abnormal (such as chipping) during the operation, which makes the operation after the milling cutter abnormal is invalid. At the same time, manual There are often problems such as inaccurate subjective judgments or even missed inspections in inspections.

The existence of the above problems not only produces waste but also increases the risk of rail damage caused by rail milling
