DETAILED DESCRIPTION

[0024] 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 intended to limit the present invention.

[0025] Please also read Figure 1 and Figure 2 , the protective device of the rail displacement monitor provided by the present invention is now described. The protective device of the rail displacement monitor includes a protective cover 1, a protective shell 2 and a connecting seat 3. The protective cover 1 is arranged outside the fixed part 401 of the displacement detector, and the protective cover 1 can be extended and retracted along a first path, and the first path is parallel to the sliding path of the detection part 402 of the displacement detector. The protective cover 1 includes a first cover body 101 and a second cover body 102 respectively located on both sides of the detection part 402; the protective shell 2 is arranged outside the detection part 402, and can slide with the detection part 402, and the protective shell 2 is respectively connected to the first cover body 101 and the second cover body 102; the connecting seat 3 is arranged on the protective shell 2, and is used for sliding connection with the rail.

[0026] Compared with the prior art, the protective device for the rail displacement monitor provided by the present invention has a protective cover 1 which is arranged outside the fixed part 401, and the first cover body 101 and the second cover body 102 are respectively connected to the detection part 402, and can be extended and retracted along the first path as the detection part 402 slides, so as to avoid interference with the detection part 402 when it moves, and at the same time, can prevent rain or dust from eroding the fixed part 401. The protective shell 2 is arranged outside the detector to protect the detection part 402, and at the same time, can provide support for the connecting seat 3. The connecting seat 3 is slidably connected to the rail, and moves synchronously with the sliding of the detection part 402, so as to improve the stability of the detection part 402 during the sliding process. The structure of the present invention is simple, and can effectively protect the displacement detection device 4, prevent the displacement detection device 4 from being eroded by wind, rain, dust, etc., and improve its service life. At the same time, it can improve the stability of the detection part 402 during the movement, and ensure the detection accuracy.

[0027] Optionally, the first cover body 101 and the second cover body 102 are both bellows, and the protective shell 2 is a rigid component, such as a plastic component or a stainless steel component.

[0028] It should be noted that the displacement detection device 4 includes a fixed part 401 connected to two adjacent sleepers, and an inspection part slidably arranged on the fixed part 401. The fixed part 401 is arranged along the first path, and the two ends of the fixed part 401 are respectively connected to two adjacent sleepers. The detection part 402 detects the displacement of the rail when sliding along the fixed part 401.

[0029] In some embodiments, see Figure 1 A receiving groove 302 is provided on the connecting seat 3 along the first path, and the receiving groove 302 is used for clamping with the rail.

[0030] In this embodiment, the accommodating groove 302 is engaged with the bottom of the rail, limiting the connection seat 3 in the up and down directions and in the direction perpendicular to the first path, so that the connection seat 3 slides along the rail, thereby connecting the detection part 402 to the rail.

[0031] In some embodiments, see Figure 2 , a temperature sensor and a humidity sensor are also provided in the protective shell 2.

[0032] The temperature sensor and the humidity sensor detect the temperature and humidity in the protective shell 2 respectively to prevent the temperature or humidity from exceeding a predetermined range and affecting the detection accuracy.

[0033] Optionally, the temperature detector 6 and the humidity detector 7 are respectively connected to an alarm, and a control component is provided in the alarm. When the temperature detector 6 detects that the temperature exceeds a first preset range, a first alarm signal is generated, and the control component controls the alarm to issue a first alarm according to the first alarm signal. When the humidity detector 7 detects that the humidity exceeds a second preset range, a second alarm signal is generated, and the control component controls the alarm to issue a second alarm according to the second alarm signal.

[0034] It should be noted that the first preset range refers to setting a minimum temperature value and a maximum temperature value in the temperature detector 6. When the temperature is between the minimum temperature value and the maximum temperature value, it is within the first preset range. The minimum temperature value and the maximum temperature value can be adaptively modified according to the actual environment, and are not unique and fixed values. The difference between the minimum temperature and the maximum temperature and the atmospheric temperature should be within 8°C.

[0035] Optionally, the alarm is communicatively connected to the operation terminal, and can transmit the first alarm signal or the second alarm signal to the operation terminal to promptly notify the operator.

[0036] In some embodiments, see Figure 1 and Figure 2 The protective device of the rail displacement monitor further includes an air duct 5 connected to the first cover body 101 or the second cover body 102, and an air inlet end of the air duct 5 is connected to the outside.

[0037] The air duct 5 is connected to the outside, so that the air in the first cover body 101 or the second cover body 102 can circulate with the external air, thereby preventing heat or moisture from accumulating in the first cover body 101 or the second cover body 102 and causing damage to the displacement detection device 4.

[0038] Optionally, the protective shell 2 is also connected to the outside through the air duct 5 .

[0039] In some embodiments, see Figure 1 The air duct 5 is connected to one end of the first cover body 101 or the second cover body 102 which is away from each other, and a filter screen is provided at the air inlet end of the air duct 5.

[0040] The filter can filter external debris or dust to maintain a clean environment in the first cover body 101 or the second cover body 102 to avoid affecting the normal operation of the detection unit 402.

[0041] In some embodiments, see Figure 3 The protective device of the rail displacement monitor also includes a cleaning component connected to the detection part 402 , and the cleaning component is used to clean the dust on the fixing part 401 .

[0042] During long-term use, a certain amount of dust will accumulate on the fixing part 401, thereby affecting the sliding of the detection part 402 along the first path. The cleaning component is connected to the detection part 402, and cleans the dust on the fixing part 401 as the detection part 402 slides, thereby preventing the connection between the detection part 402 and the fixing part 401 from rusting, thereby increasing the service life of the displacement detection device 4.

[0043] In some embodiments, see Figure 3 The cleaning assembly includes flexible cleaning blocks 8 respectively connected to both sides of the detection portion 402 along the first path.

[0044] The flexible cleaning block 8 can prevent the fixing part 401 from being worn or scratched, and can also effectively clean the dust on the fixing part 401 , thereby increasing the service life of the displacement detection device 4 .

[0045] Optionally, the flexible cleaning block 8 may be a sponge block or a rubber block.

[0046] Specifically, the flexible cleaning block 8 can be adhered to both sides of the detection portion 402 .

[0047] As another specific embodiment of the cleaning component, please refer to Figure 4 The cleaning component also includes a connecting member 11 respectively connected to the flexible cleaning block 8 and the detection part 402, the connecting member 11 includes a first connecting part 1101 arranged along the first path, and a second connecting part 1102 arranged along the second path, the second path is perpendicular to the first path, and the flexible cleaning block 8 is rotatably connected to the second connecting part 1102, and the first connecting part 1101 is connected to the detection part 402.

[0048] In this embodiment, when the detection part 402 moves along the first path, the connecting member 11 and the flexible cleaning block 8 move synchronously. Since the flexible cleaning block 8 is in contact with the fixed part 401, the flexible cleaning block 8 rotates under the action of friction, and the sliding friction is converted into rolling friction, thereby reducing the wear on the fixed part 401. At the same time, the cleaning area on the flexible cleaning block 8 can be increased, thereby preventing a certain part of the flexible cleaning block 8 from continuously contacting the fixed part 401, causing dust to accumulate in that part and affecting the cleaning effect, and also avoiding a reduction in the service life of the flexible cleaning block 8 due to local wear.

[0049] Optionally, the flexible cleaning block 8 is a columnar component and is coaxially connected to the second connecting portion 1102 .

[0050] In some embodiments, see Figure 3 The cleaning assembly further includes a lubrication tank 10 disposed at the detection portion 402 . The lubrication tank 10 is provided with lubrication oil for spraying the lubrication oil toward the fixing portion 401 .

[0051] The lubrication tank 10 can spray lubricating oil onto the fixing portion 401 , so that the detection portion 402 can slide smoothly along the fixing portion 401 , thereby preventing rust from occurring between the detection portion 402 and the fixing portion 401 and affecting the normal operation of the displacement detection device 4 .

[0052] Specifically, a switch valve is provided on the lubrication tank 10, and the switch valve is communicatively connected with the operation terminal, and the opening or closing of the switch valve can be controlled by the operation terminal.

[0053] In some embodiments, see Figure 3 The protective cover 1 is connected to the protective shell 2 , and the rail displacement detection device 4 also includes a fan 9 connected to the detection part 402 , and the fan 9 is used to blow off the dust on the fixing part 401 .

[0054] During long-term use, dust and impurities will accumulate on the fixing part 401 and the detection part 402. The fan 9 can clean the dust on the fixing part 401 to ensure that the detection part 402 slides along the fixing part 401. In addition, the fan 9 can also accelerate the flow of air in the protective cover 1 and the external air to avoid the accumulation of moisture and heat in the protective cover 1.

[0055] Specifically, the fan 9 is provided with a battery.

[0056] In some embodiments, see Figure 3 The temperature sensor, humidity sensor and fan 9 are respectively connected to the controller for communication.

[0057] When the temperature sensor detects that the temperature inside the protective cover 1 exceeds the first preset value, a first alarm signal is generated, and the controller controls the fan 9 to turn on according to the first alarm signal, accelerates the gas circulation inside the protective cover 1, and reduces the temperature inside the protective cover 1; when the temperature sensor detects that the temperature inside the protective cover 1 is lower than the second preset value, a second alarm signal is generated, and the controller controls the fan 9 to turn off according to the second alarm signal. When the humidity detector 7 detects that the humidity inside the protective cover 1 is higher than the third preset value, a third alarm signal is generated, and the controller controls the fan 9 to turn on according to the third alarm signal, accelerates the gas circulation inside the protective cover 1, and reduces the humidity inside the protective cover 1; when the humidity detector 7 detects that the humidity inside the protective cover 1 is lower than the fourth preset value, a fourth alarm signal is generated, and the controller controls the fan 9 to turn off according to the fourth alarm signal. The structure in this embodiment can automatically control the opening or closing of the fan 9, thereby adjusting the temperature and humidity inside the protective cover 1, ensuring the normal operation of the displacement detection device 4, and improving the inspection accuracy of the displacement detection device 4.

[0058] It should be noted that environmental factors such as atmospheric temperature and humidity vary greatly in different seasons. The specific values ​​of the first preset value, the second preset value, the third preset value and the fourth preset value are adjusted according to the actual conditions of the atmospheric environment to control the changes in temperature, humidity, etc. of the rail displacement monitor within a certain range to avoid damage to the rail displacement monitor or inaccurate monitoring results due to excessive changes in temperature, humidity, etc.

[0059] Specifically, the difference between the first preset value and the atmospheric temperature is 5-8° C., and the difference between the second preset value and the atmospheric temperature is 5-8° C. The difference between the third preset value and the fourth preset value and the atmospheric humidity should be less than 60%, respectively.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
