[0025] The following is combined with Figure 1-9 The present invention is described in further detail. Example

[0026] Reference Figure 1 The railway maintenance and inspection equipment includes a maintenance trolley 1, a cleaning device 2 and a gauge measuring device. The maintenance trolley 1 can move along the rail 100. The cleaning device 2 is arranged at the front of the maintenance trolley 1 and is configured to clean the rail 100. The gauge measuring device is arranged in the middle of the maintenance trolley 1 and is configured to detect the gauge of the rail 100. The railway maintenance and inspection equipment also includes a coating device 5 or a flaw detection device 6. Either the coating device 5 or the flaw detection device 6 is arranged at the rear of the maintenance trolley 1. The coating device 5 is configured to coat the surface of the rail 100 with a curing agent, and the flaw detection device 6 is configured to detect flaws on the rail 100. In this embodiment, the coating device 5 is arranged at the rear of the maintenance trolley 1.

[0027] Based on the above, when the railway maintenance and inspection equipment is in operation, the rail 100 is first cleaned by the cleaning device 2, and then the track gauge is measured by the track gauge measuring device, and then the maintenance agent is promptly coated on the rail 100 by the coating device 5.

[0028] It should be noted that the maintenance trolley 1 in this embodiment includes a car body 11 and wheels 12, wherein the car body 11 is welded with pipes; the wheels 12 are rotatably connected to the car body 11, and two wheels 12 are provided for each rail 100. The structure of the wheels 12 is set with reference to the train wheels 12, that is, a limiting plate (not shown in the figure) is provided on the side of each wheel 12 close to the inner side of the car body 11 to limit the wheel 12, so that the maintenance trolley 1 can move along the rail 100, and the two wheels 12 close to the front of the car are driven by a motor to realize the independent movement of the maintenance trolley 1. In addition, a battery 111 and a controller are also connected to the car body 11, and the battery 111 and the motor are electrically connected to the controller. The battery 111 supplies power to the maintenance trolley 1, and the controller controls the motor.

[0029] Reference Figure 2 and Figure 3 Specifically, the cleaning device 2 includes a cleaning arm 21 and a cleaning head 22. The cleaning arm 21 is arranged at the front of the maintenance trolley 1 along the lateral direction of the maintenance trolley 1. The cleaning arm 21 is connected to the maintenance trolley 1 through a connecting arm 211. One end of the connecting arm 211 is rotatably connected to the body 11 of the maintenance trolley 1, and the connection point is located at the top of the body 11. The other end of the connecting arm 211 is fixedly connected to the cleaning arm 21, and the rotation axis of the connecting arm 211 is parallel to the axis of the cleaning arm 21. The cleaning arm 21 is rotatably connected to the body 11, so that the cleaning arm 21 has a certain degree of freedom. When working, it can be overlapped on the rail 100, and when not working, it can be rotated to the top of the body 11, so as to achieve storage.

[0030] A cleaning head 22 is provided at both ends of the cleaning arm 21. A single cleaning head 22 can clean a single rail 100. Each cleaning head 22 includes a cleaning top plate 221 and a cleaning side plate 222. The cleaning top plate 221 is located at the top of the rail 100. The bottom of the cleaning top plate 221 is connected with a first cleaning member 2211, and the first cleaning member 2211 abuts the rail 100. A cleaning side plate 222 is provided on both sides of the length direction of the rail 100. The cleaning top plate 221 is located between the two cleaning side plates 222, and the top of the cleaning side plate 222 is rotatably connected to the cleaning top plate 221. The opposite side of the two cleaning side plates 222 is connected with a second cleaning member 2221, and the second cleaning member 2221 abuts the rail 100. The second cleaning member 2221 can clean the rail 100.

[0031] Optionally, the first cleaning piece 2211 and the second cleaning piece 2221 in the present embodiment may be cleaning brushes made of metal, and the side of the second cleaning piece 2221 close to the rail 100 may be contoured according to the shape of the rail 100, that is, the second cleaning piece 2221 abuts against one side of the rail 100 and is arranged parallel to the side of the rail 100, thereby improving the cleaning effect of the rail 100.

[0032] In order to limit the cleaning side plate 222 and make the second cleaning piece 2221 close to the rail 100, an elastic limiting card 23 is provided on each cleaning top plate 221, and each elastic limiting card 23 includes a first card 231 and a second card 232. The first card 231 is located on the top of the cleaning top plate 221, and the second card 232 is provided on the opposite side of the two second cleaning pieces 2221. The top of the second card 232 is connected to the first card 231, and the second card 232 abuts against the cleaning side plate 222.

[0033] Exemplarily, in this embodiment, the first card 231 and the second card 232 are both metal sheets and have a certain elasticity. The first card 231 and the second card 232 are integrally formed, and the angle between the first card 231 and the second card 232 is less than 90 degrees, thereby forming an elastic limiting space between the two second cards 232.

[0034] Based on the above arrangement, before the cleaning device 2 operates, it is necessary to first rotate the connecting arm 211 so that the cleaning arm 21 overlaps the rail 100, and make the cleaning top plate 221 and the cleaning side plate 222 fit the rail 100, and then install the elastic limit card 23 on each cleaning top plate 221, and abut the cleaning side plate 222 inwardly through the two second cards 232, so that the second cleaning member 2221 is close to the rail 100, thereby ensuring the cleaning effect of the rail 100. When the maintenance trolley 1 is in motion, the two rails 100 can be cleaned by the first cleaning member 2211 and the second cleaning member 2221.

[0035] Reference Figure 4 and Figure 5The track gauge measuring device includes a dynamic detection mechanism 3 and a static detection mechanism 4. The dynamic detection mechanism 3 is configured to detect the track gauge of the rail 100 during the movement of the maintenance trolley 1, and the dynamic and static detection mechanism 4 is configured to detect the track gauge of the rail 100 when the maintenance trolley 1 is stationary. The dynamic detection mechanism 3 includes a detection arm 31, a detection wheel 32 and a detection member 33. The detection arm 31 is located at the bottom of the vehicle body 11. The detection arm 31 is arranged along the lateral direction of the maintenance trolley 1, that is, the detection arm 31 is arranged horizontally, and the detection arm 31 and the maintenance trolley 1 are connected by a first elastic member 311. A detection wheel 32 is slidably arranged at both ends of the detection arm 31, and the detection wheel 32 can rotate. The detection wheel 32 slides along the axis of the detection arm 31. A limiting ring groove 321 is provided on the outer periphery of the detection wheel 32, and a part of the rail 100 is embedded in the limiting ring groove 321. A detection member 33 is fixedly provided at each end of the detection arm 31, and the detection member 33 can detect the distance between itself and the detection wheel 32 in the lateral direction of the maintenance trolley 1. Exemplarily, the first elastic member 311 in this embodiment is a spring, and when part of the rail 100 is embedded in the limiting ring groove 321, the spring is in a compressed state. The detection member 33 in this embodiment is a distance sensor, and the distance sensor is electrically connected to the controller.

[0036] Based on the above, during the forward movement of the maintenance trolley 1, the detection wheel 32 is limited by the rail 100, so that the detection wheel 32 always rolls on the top of the rail 100 and can slide along the axial direction of the detection arm 31; during this process, the distance between itself and the detection wheel 32 is detected in real time through two distance sensors 43. Since the distance between the two distance sensors 43 is fixed, the controller can accurately calculate the current track gauge.

[0037] In addition, since the detection arm 31 is suspended below the vehicle body 11 and connected to the vehicle body 11 through a spring, it can be understood that the two detection wheels 32 only bear the gravity of themselves and the detection arm 31, but not the gravity of the maintenance trolley 1, so that the two detection wheels 32 are easier to slide along the axial direction of the detection arm 31, and are not easy to get stuck when encountering a position with a larger track gauge and a position of a bend in the rail 100 during the forward movement of the maintenance trolley 1, and the detected data is more accurate. In addition, a weak elastic force is applied to the detection wheel 32 through the spring, which can prevent the detection wheel 32 from moving upward and causing the rail 100 to disengage from the limiting ring groove 321, thereby improving the stability of the work.

[0038] Furthermore, a sleeve 112 is connected to the car body 11. In the present embodiment, the sleeve 112 is vertically arranged. A guide rod 312 is slidably penetrated inside the sleeve 112. The guide rod 312 is perpendicular to and connected to the detection arm 31. The sleeve 112 limits the detection arm 31 to a certain extent, so that the detection arm 31 can only move in the vertical direction. At the same time, since only one guide rod 312 is provided, the detection arm 31 can also rotate around the axis of the guide rod 312. Therefore, when the maintenance trolley 1 passes through the bend of the rail 100, the detection arm 31 and the car body 11 can produce a small angle of rotation in the lateral direction, which can improve the flexibility of the detection wheel 32 and improve the accuracy of the detection data.

[0039] Furthermore, a positioning member 3121 is also provided on the guide rod 312. The positioning member 3121 is a screw threadedly connected to the guide rod 312. The positioning member 3121 has a first position located below the sleeve 112 and a second position located above the sleeve 112. When the positioning member 3121 is in the first position, the axial distance between the positioning member 3121 and the sleeve 112 along the guide rod 312 is less than the depth of the limiting ring groove 321. When the positioning member 3121 is in the second position, the detection wheel 32 is spaced apart from the rail 100.

[0040] By setting the positioning member 3121, when the dynamic detection mechanism 3 works normally, the positioning member 3121 is in the first position, thereby limiting the upwardly moving guide rod 312, so that the upward movement stroke of the guide rod 312 is less than the depth of the limiting ring groove 321, that is, the upward movement stroke of the detection arm 31 is less than the depth of the limiting ring groove 321, which can prevent the detection wheel 32 from being separated from the rail 100. When the dynamic detection mechanism 3 stops working, the positioning member 3121 can be removed, and the guide rod 312 can be slid upward, and then the positioning member 3121 can be installed again, so that the positioning member 3121 is in the second position, at which time the detection wheel 32 is spaced apart from the rail 100, that is, the detection wheel 32 is in a suspended state, thereby preventing the detection wheel 32 from being worn except for normal operation.

[0041] Preferably, in order to axially limit the two detection wheels 32, two limiting cylinders 313 are fixedly sleeved at both ends of the detection arm 31, the two limiting cylinders 313 are arranged at intervals, the detection wheel 32 is located between the two limiting cylinders 313, and a second elastic member (not shown in the figure) is abutted between the two limiting cylinders 313 and the detection wheel 32. The second elastic member is a spring, which is sleeved on the outside of the detection arm 31, and the second elastic member is in a compressed state. The limiting cylinder 313 is provided to prevent the detection wheel 32 from detaching from the detection arm 31, and at the same time, the two springs continuously apply thrust to the detection wheel 32, so that the detection wheel 32 always has a tendency to move toward the center of the two limiting cylinders 313, preventing the detection wheel 32 from getting stuck when moving along the axial direction of the detection arm 31.

[0042] Reference Figure 6 The static detection mechanism 4 includes a detection plate 41, a detection head 42 and a sensor 43. The detection plate 41 is connected to the bottom of the maintenance trolley 1. The detection plate 41 is arranged horizontally along the maintenance trolley 1. The detection plate 41 is located on the side of the detection arm 31 close to the rear of the vehicle. A detection head 42 is slidably arranged at both ends of the detection plate 41. Both detection heads 42 slide along the length direction of the detection plate 41. The detection head 42 is arranged vertically, and the top of the detection head 42 is connected to the detection plate 41. The bottom of the detection head 42 is located on the opposite side of the two rails 100. In this embodiment, the sliding of the detection head 42 is driven by an electric cylinder. In some other embodiments, the sliding of the detection head 42 can also be driven by a linear drive member such as a cylinder or an oil cylinder. A sensor 43 is provided for each detection head 42. The sensor 43 is fixedly connected to the detection plate 41. The sensor 43 can detect the sliding distance of the detection head 42 in the lateral direction of the maintenance trolley 1. The sensor 43 in this embodiment is a distance sensor. The distance sensor is electrically connected to the controller, that is, it calculates the current track gauge by detecting the distance between itself and the detection head 42.

[0043] By setting the above-mentioned static detection mechanism 4, when the track gauge data measured by the dynamic detection mechanism 3 is abnormal, the maintenance trolley 1 stops moving forward, and the two detection heads 42 can be driven by the electric cylinder to slide in the direction close to the rail 100 until the detection head 42 abuts against the rail 100. At this time, the track gauges of the two rails 100 can be calculated by the data measured by the two distance sensors 43, so that the track gauges can be measured twice by the static detection mechanism 4 with different structures, thereby improving the precision and accuracy of the detection. In addition, the track gauge can be measured at fixed points by the static detection mechanism 4 at intervals to reduce the error of the data, and the dynamic detection mechanism 3 can be calibrated in time.

[0044] It should be noted that the spacing between the detection plate 41 and the detection arm 31 in the longitudinal direction of the vehicle body 11 is the distance that the maintenance trolley 1 moves from a moving state to a stationary state when the track gauge data measured by the dynamic detection mechanism 3 is abnormal. It can be understood that when the dynamic detection mechanism 3 measures that the track gauge data at point A is abnormal, after the maintenance trolley 1 stops, the static detection mechanism 4 happens to be at point A, so there is no need to adjust the position of the maintenance trolley 1, even if the positions of the two detections coincide.

[0045] Reference Figure 7 and Figure 8The coating device 5 includes a coating arm 51, a coating head 52 and a maintenance agent supply mechanism. Two coating arms 51 are arranged along the transverse direction of the maintenance trolley 1. Two first rotating seats 113 are detachably connected to the rear of the vehicle body 11. One end of the coating arm 51 is rotatably connected to the rotating seat, and the rotation axis is parallel to the transverse direction of the vehicle body 11. The other end of the coating arm 51 extends out of the vehicle body 11. A coating head 52 is rotatably connected to the other end of each coating arm 51, and the rotation axis is parallel to the transverse direction of the vehicle body 11. The coating head 52 can apply maintenance agent to the rail 100. Specifically, each coating head 52 includes a coating top plate 521 and a coating side plate 522. The coating top plate 521 is located at the top of the rail 100. The bottom of the coating top plate 521 is connected to a first coating member 5211, and the first coating abuts the rail 100. A coated side panel 522 is provided on both sides of the length direction of the rail 100, a coated top panel 521 is located between the two coated side panels 522, and the top of the coated side panel 522 is rotatably connected to the coated top panel 521, the rotational resistance of the coated side panel 522 is greater than its own gravity, and the opposite sides of the two coated side panels 522 are connected to a second coating member 5221, the second coating member 5221 abuts against the rail 100, the first coating member 5211 and the second coating member 5221 are both sponges or foams that can absorb and apply the curing agent, and this embodiment takes a sponge as an example.

[0046] The maintenance agent supply mechanism includes a liquid storage tank 53 and a liquid infusion tube. The liquid storage tank 53 is connected to the vehicle body 11. The maintenance agent is stored inside the liquid storage tank 53. There is a liquid infusion tube between the liquid storage tank 53 and each first coating member 5211, and a valve is provided at the inlet end of the liquid infusion tube.

[0047] When the coating device 5 is working, the first coating member 5211 and the second coating member are placed close to the rail 100, and after the valve is opened, the curing agent is transported to the first coating member 5211 through the infusion tube, so that the first coating member 5211 and the second coating member 5221 absorb and store the curing agent, and apply the curing agent to the rail 100 while following the maintenance trolley 1.

[0048] In addition, a position for placing rail 100 maintenance tools may be reserved on the vehicle body 11 , thereby facilitating maintenance operations such as tightening bolts on the rail 100 by the staff.

[0049] This embodiment also discloses a railway maintenance method, which is based on a railway maintenance detection device and includes the following steps: According to maintenance needs, a coating device 5 or a flaw detection device 6 is pre-installed at the rear of the maintenance vehicle 1. In this embodiment, the coating device 5 is taken as an example. Thus, the required devices can be freely matched according to maintenance needs, thereby improving the adaptability of the equipment.

[0050] The maintenance trolley 1 is placed on the rail 100 so that the front of the maintenance trolley 1 faces the forward direction.

[0051] The maintenance trolley 1 is controlled to move forward. During the movement, the maintenance trolley 1 first cleans the rail 100 through the cleaning device 2, and then measures the track gauge of the rail 100 through the dynamic detection mechanism 3, and records the detection data, so that the track gauge can be continuously measured.

[0052] When the controller calculates that the track gauge data measured by the dynamic detection mechanism 3 is abnormal, the controller controls the maintenance trolley 1 to stop moving, and measures the track gauge at this location again through the static detection mechanism 4, and records the detection data. Then the controller compares the data detected by the dynamic detection mechanism 3 and the static detection mechanism 4. If the data detected by the dynamic detection mechanism 3 and the static detection mechanism 4 are consistent, the maintenance trolley 1 moves forward and continues to measure the track gauge through the dynamic detection mechanism 3; if the data detected by the dynamic detection mechanism 3 and the static detection mechanism 4 are inconsistent, they are manually rechecked. In this way, the accuracy of the detection data can be improved, and problems with the dynamic detection mechanism 3 and the static detection mechanism 4 can be discovered in a timely manner.

[0053] Every time the maintenance trolley 1 moves forward a certain distance, the maintenance trolley 1 is controlled to stop moving, and the track gauge at this location is measured by the static detection mechanism 4, and the detection data is recorded. Example

[0054] Reference Fig. 9 The difference between this embodiment and the first embodiment is that in this embodiment, only a flaw detection device 6 is provided at the rear of the maintenance trolley 1. The flaw detection device 6 includes a flaw detection arm 61 and a magnetic flaw detection head 62. Two flaw detection arms 61 are provided along the lateral direction of the vehicle body 11. The rear of the vehicle body 11 is detachably connected to two second rotating seats 114. One end of each flaw detection arm 61 is rotatably connected to the second rotating seat 114. The other end of the flaw detection arm 61 extends out of the rear of the vehicle body 11. The magnetic flaw detection head 62 is connected to the other end of the flaw detection arm 61. The magnetic flaw detection head 62 is located above the rail 100 and is electrically connected to the controller. During the forward movement of the maintenance trolley 1, the magnetic flaw detection head 62 continuously detects flaws on the rail 100, and transmits the flaw detection data to the controller.
