Most of these temperature measurement methods have the problems of low efficiency, high time cost and complex operation, and cannot meet the current requirements of high efficiency, high benefit and high automation level of railway seamless lines.

[0004] Therefore, how to provide a non-contact rail temperature infrared measurement device to achieve rapid measurement of rail temperature through infrared laser temperature measurement technology, while simplifying the structure and operating steps, has become a technical problem that needs to be urgently solved by people in this field.

DETAILED DESCRIPTION

[0027] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0028] like Figure 1-5 As shown, a non-contact rail temperature infrared measuring device includes a base 1, a chassis body 2, a temperature measuring device 3, a display device 4, a controller 5 and a battery 6. The base 1 is arranged at the bottom of the chassis body 2, and is used to support the chassis body 2 and place it on one side of the rail 7 to be measured. The chassis body 2 is provided with an opening 21 on the side close to the rail 7. The temperature measuring device 3 is installed on the inner cavity wall of the chassis body 2 on the side where the opening 21 is provided, and the working end of the temperature measuring device 3 is extended outward through the opening 21. The display device 4 is arranged on the top of the chassis body 2. The controller 5 and the battery 6 are both built in the inner cavity of the chassis body 2. The battery 6 is electrically connected to the controller 5, and the temperature measuring device 3 and the display device 4 are both electrically connected to the controller 5.

[0029] Specifically, the base 1 includes a supporting base 11, an adjustable support frame 12 and a support pad 13. The top of the supporting base 11 is fixedly connected to the bottom of the chassis body 2. A plurality of adjustable support frames 12 are hingedly distributed in a circular shape at the bottom of the supporting base 11. The support pad 13 for contacting the ground is connected to the bottom end of the adjustable support frame 12 by a ball joint.

[0030] Specifically, the adjustable support frame 12 includes a first telescopic arm, a second telescopic arm and a fixing bolt. The first telescopic arm is slidably mounted on the second telescopic arm, and the fixing bolt is threadedly connected to one end of the first telescopic arm close to the second telescopic arm. At the same time, the user can also use an electric telescopic rod or other lifting structures that can be used to assist in adjusting the position height of the chassis body 2.

[0031] Specifically, the setting of the adjustable support frame 12 enables the device to freely adjust the height. When the user places the device on the side of the rail to be temperature measured, the telescopic length of the adjustable support frame 12 can be freely adjusted according to actual conditions, so that the working end of the infrared sensor probe 32 can be kept level with the area to be temperature measured on the rail, thereby ensuring that the infrared radiation signal emitted by the infrared sensor probe 32 can be transmitted to the area to be temperature measured, thereby completing the measurement operation of the rail temperature.

[0032] Specifically, the hinged connection between the adjustable support frame 12 and the chassis body 2 makes it easy for the user to individually adjust the support angle of each adjustable support frame 12 according to the actual situation on site. The support pad 13 connected to the bottom end of the adjustable support frame 12 with a ball joint makes the device suitable for placement on more uneven terrains, ensuring that the device can smoothly and safely complete the measurement operation of the rail temperature.

[0033] Specifically, the controller 5 includes a main board 51 and a control chip 52. The main board 51 is fixedly installed in the inner cavity of the chassis body 2. The control chip 52 is electrically connected to the main board 51. The battery 6 is electrically connected to the main board 51 and is used to provide the required power for the control chip 52 during operation. The temperature measuring device 3 and the display device 4 are both electrically connected to the control chip 52 through the main board 51.

[0034] Specifically, a power switch 8 and a charging port 9 are further provided on one side of the chassis body 2 . The power switch 8 is electrically connected between the battery 6 and the main board 51 , and the charging port 9 is electrically connected to the battery 6 .

[0035] Specifically, the provision of the storage battery 6 allows the device to get rid of the constraints of the power cord, thereby facilitating the measurement of the outdoor rail temperature. At the same time, the device is provided with a charging port 9, which can replenish the battery 6 when not in operation, thereby extending the working life of the device.

[0036] Specifically, the temperature measuring device 3 includes a temperature measuring device body 31, an infrared sensor probe 32 and a temperature sensor. The temperature measuring device body 31 is installed on the inner cavity wall of the chassis body 2 on the side where the opening 21 is provided. The infrared sensor probe 32 is installed at one end of the temperature measuring device body 31 and extends outward through the opening 21. The temperature sensor is arranged inside the temperature measuring device body 31. After the infrared sensor probe 32 and the temperature sensor are electrically connected together, they are both electrically connected to the control chip 52.

[0037] Specifically, the working end of the infrared sensor probe 32 is also provided with a lens 33 for focusing and transmitting infrared radiation signals.

[0038] Specifically, the working principle of the temperature measuring device 3 is as follows: Figure 6 As shown, infrared laser measurement of rail temperature mainly utilizes the principle that all objects in nature continuously radiate energy to the external environment. The temperature of the object to be measured is detected by collecting and processing the heat rays radiated by the object.

[0039] After the measurement starts, the heat rays radiated by the rail to be measured enter the temperature measuring device body 31 through the lens 33 at the front end of the infrared sensor probe 32. After the lens 33 converges the heat rays, the heat rays pass through the filter to filter the heat rays outside the specified analysis wavelength. The filtered heat rays pass through the modulation disk and enter the infrared sensor. The infrared sensor performs thermal drift reduction processing on the heat rays of the specified wavelength, and the stability of the heat rays of the wavelength to be measured is ensured by performing operations such as forward and selective release on the heat rays. After the heat rays are synchronously calibrated by the multi-input motor-driven multi-spectrum server, the heat rays are emitted to the temperature sensor, which converts the optical signal into an electrical signal and amplifies it. The linearization processing of the electrical signal is realized through the regulation of the adder in the automatic zeroing circuit, and the data output in the form of chopping (AC and DC) is realized at the same time, and the non-contact infrared laser measurement of the rail temperature is realized.

[0040] Specifically, the display device 4 includes a display screen 41, a temperature measurement start indicator light 42 and a temperature measurement completion indicator light 43. The display screen 41 is embedded in the top of the chassis body 2, and the temperature measurement start indicator light 42 and the temperature measurement completion indicator light 43 are arranged on the side of the top of the chassis body 2 away from the display screen 41. The display screen 41, the temperature measurement start indicator light 42, and the temperature measurement completion indicator light 43 are all electrically connected to the control chip 52.

[0041] The use process of the utility model is as follows:

[0042] First, place the device around the rail 7 to be tested, and adjust the height of the base 1 until the working end of the infrared sensor probe 32 is level with the area of ​​the rail 7 to be tested.

[0043] Then, turn on the power switch 8 of the device, at this time, the temperature measurement start indicator light 42 lights up, the infrared sensor probe 32 collects the heat rays on the surface of the measured rail 7 through the infrared radiation signal and converts it into an electrical signal, and the electrical signal is transmitted to the control chip 52 through the line. The control chip 52 will process the measured electrical signal and transmit the result information to the display screen 41 through the line for digital display;

[0044] Finally, after the display screen 41 displays the measurement result of the current rail 7 temperature, the temperature measurement start indicator light 42 goes out and the temperature measurement completion indicator light 43 lights up. The user can turn off the power switch 8 after recording the result to complete the measurement operation of the rail 7 temperature.
