[0050] Specifically, if Figure 1 、 Figure 2 、 Figure 4 and Figure 5As shown, the adjusting part 31 includes a first adjusting structure, a second adjusting structure, and a fixing structure 314. Among them, the first adjusting structure is rotatably arranged on the connecting frame 1, the second adjusting structure is telescopically arranged on the first adjusting structure, the fixing structure 314 is arranged on the second adjusting structure, and the monitor 32 is installed on the fixing structure 314.

With such an arrangement, the flexible adjustment of the monitor 32 can be achieved to ensure that they can always be in the best monitoring position.

[0051] In this embodiment, the first adjusting structure includes a rotating shaft 3132 and a rotating seat 3133. Among them, the rotating seat 3133 is detachably sleeved on the rotating shaft 3132, the second adjusting structure is telescopically arranged on the rotating seat 3133, and the rotating shaft 3132 is rotatably arranged on the connecting frame 1 to drive the rotation of the rotating seat 3133.

[0052] Optionally, the adjusting part 31 further includes a first connecting plate 311, a second connecting plate 312, and a driving motor 3131.

In this way, the driving motor 3131 can drive the rotation of the rotating shaft 3132. At the same time, the other end of the rotating shaft 3132 passes through the first connecting plate 311 and the second connecting plate 312 in sequence and is rotatably connected to the first connecting plate 311 and the second connecting plate 312. In this way, the rotating shaft 3132 can drive the rotation of the rotating seat 3133, thereby achieving the purpose of adjusting the angle of the monitor 32.

[0053] Specifically, the second adjusting structure is a lifting rod 3134. The two ends of the lifting rod 3134 are respectively connected to the rotating seat 3133 and the fixing structure 314. The lifting rod 3134 can drive the lifting of the fixing structure 314, thereby achieving the purpose of adjusting the height of the monitor 32 and further ensuring that the monitor 32 is always in the best monitoring position. Among them, the lifting rod 3134 includes but is not limited to an electric lifting rod.

[0054] Further, to facilitate the installation and disassembly between the rotating shaft 3132 and the rotating seat 3133, the first adjustment structure further includes a limiting rod 3135 and a fastening mechanism 3136. The rotating seat 3133 has a limiting groove 3137 and a receiving groove 3138 that communicate with each other. Among them, the rotating shaft 3132 is located in the receiving groove 3138. The limiting rod 3135 is connected to the rotating shaft 3132 and is located in the limiting groove 3137, so that the rotating shaft 3132 can drive the rotating seat 3133 to rotate. At the same time, the fastening mechanism 3136 is rotatably passed through the rotating seat 3133. With such a setting, by rotating the fastening mechanism 3136, the purpose of clamping or avoiding the rotating shaft 3132 located in the receiving groove 3138 can be achieved, that is, the purpose of facilitating the installation and disassembly between the rotating shaft 3132 and the rotating seat 3133 is achieved. Among them, the fastening mechanism 3136 includes a screw rod and a nut, and the screw rod and the nut cooperate with each other to clamp or avoid the rotating shaft 3132 located in the receiving groove 3138.

[0055] Optionally, there is at least one rotating seat 3133, lifting rod 3134, fixing structure 314, and monitor 32. The rotating seats 3133 and the lifting rods 3134 are arranged in one-to-one correspondence, the lifting rods 3134 and the fixing structures 314 are arranged in one-to-one correspondence, and the fixing structures 314 and the monitors 32 are arranged in one-to-one correspondence. This can improve the accuracy of the monitor 32 in monitoring the wheel stopper.

[0056] In this embodiment, as Figure 1 , Figure 2 and Figure 6 shown, the fixing structure 314 includes a fixing plate 3141, a clamping plate 3142, and a locking mechanism. Among them, the fixing plate 3141 and the clamping plate 3142 are pivotally connected, and the clamping plate 3142 can rotate relative to the fixing plate 3141 to have a fastening position and an open position. When the clamping plate 3142 is in the fastening position, the relative positions of the fixing plate 3141 and the clamping plate 3142 are locked by the locking mechanism, so as to achieve the purpose of clamping the monitor 32. Among them, the locking mechanism includes a screw rod 3143 and a fixing block 3144. One end of the screw rod 3143 is connected to the other end of the clamping plate 3142, the other end of the screw rod 3143 passes through the other end of the fixing plate 3141, and the fixing block 3144 passes through the other end of the screw rod 3143 and is threadedly engaged with the screw rod 3143. In this way, the clamping degree between the fixing plate 3141 and the clamping plate 3142 can be adjusted by screwing the fixing block 3144. At the same time, the fixing block 3144 can abut against the other end of the fixing plate 3141, so as to achieve the purpose of clamping the monitor 32 located between the fixing plate 3141 and the clamping plate 3142, and such a setting facilitates installation and disassembly. Among them, both the fixing plate 3141 and the clamping plate 3142 are arc-shaped plates.

[0057] Furthermore, in order to more accurately monitor the operating state of the rail vehicle, the alarm device for the rail vehicle wheel chock further includes an external sensor. The external sensor can be installed at the axle of the rail vehicle. By using the external sensor, the vibration frequency or temperature during the operation of the rail vehicle can be detected. The relative position deviation between the wheel of the rail vehicle and the wheel chock exceeds a preset pixel value (such as 8 pixels), or if there are signs of suspected rolling of the wheel, it is determined that there is a risk of vehicle creep. This can be achieved by comparing the current image with a preset standard image through image comparison.

[0058] In some embodiments, the alarm device for the rail vehicle wheel chock further includes a controller 42. The alarm assembly 4 includes a fixing bracket 41 and an alarm 43. Among them, the fixing bracket 41 is arranged on the other side of the connecting bracket 1. The controller 42 is arranged on the fixing bracket 41, and the alarm 43 is arranged on the controller 42. The alarm 43 and the monitor 32 are both communicatively connected to the controller 42. In this way, the controller 42 can receive the monitoring signal of the monitor 32 to control the alarm 43 to send out an alarm signal.

[0059] Optionally, the controller 42 has a plug 421 to facilitate the plugging of the alarm 43.

[0060] Optionally, the alarm 43 includes a sound alarm 431 and a light alarm 432, so as to timely remind the maintenance staff.

[0061] This embodiment also provides a monitoring method for a rail vehicle wheel chock, which is applied to the alarm device for a rail vehicle wheel chock in the above solution. The monitoring method for a rail vehicle wheel chock includes: first, installing the installation assembly 2 at the bottom of the rail vehicle; then adjusting the position of the monitor 32 through the adjusting part 31 so that the monitor 32 abuts against the wheel chock; monitoring the motion state of the wheel chock through the monitor 32 and transmitting the signal monitored by the monitor 32 to the controller 42; finally, if the controller 42 determines that the motion state of the wheel chock is in an abnormal state, the controller 42 controls the alarm assembly 4 to send out an alarm signal. If the controller 42 determines that the motion state of the wheel chock is not in an abnormal state, the controller 42 controls the alarm assembly 4 not to send out an alarm signal. With this setting, the alarm device for the rail vehicle wheel chock is not directly set on the wheel chock, which can effectively prevent false alarms and other situations of the alarm device for the rail vehicle wheel chock.

[0062] Specifically, if the controller 42 determines that the motion state of the wheel stopper is in an abnormal state, the controller 42 controls the alarm component 4 to emit an alarm signal, including: if the monitor 32 monitors that the pressure value of the wheel stopper exceeds the preset braking pressure value, the controller 42 controls the alarm component 4 to emit an alarm signal; among them, when the monitor 32 monitors that the pressure value of the wheel stopper exceeds 80%-120% of the preset braking pressure value, the controller 42 determines that the wheel stopper braking is abnormal and triggers an alarm signal. If the monitor 32 monitors that the displacement change value of the wheel stopper exceeds the preset displacement change value, the controller 42 controls the alarm component 4 to emit an alarm signal; for example, if the displacement of the wheel stopper on the track plane exceeds 5 mm within 10 seconds, or the displacement in the vertical direction exceeds 2 mm, it is determined that the wheel stopper has an abnormal displacement and an alarm signal is triggered. If the monitor 32 monitors that the angle of the wheel stopper exceeds the preset angle range value, the controller 42 controls the alarm component 4 to emit an alarm signal. If the inclination sensor monitors that the angle deviation of the wheel stopper exceeds ±5°, it is determined that the angle of the wheel stopper is abnormal and an alarm signal is triggered.

[0063] The advantages of the present invention are as follows:

[0064] 1. By setting the connection shell, magnetic attraction member, screw rod and mounting seat, rotating the connection shell will drive the screw rod to rotate and displace inside the mounting seat, so as to adjust the height of the magnetic attraction member to adapt to the installation conditions of different vehicle bottoms and ensure that the device can be stably attached to the vehicle bottom.

[0065] 2. By setting the rotating seat, rotating shaft, driving motor, lifting rod and fixing structure, after starting the driving motor, its output end immediately drives the rotating shaft to rotate, the rotating shaft drives the rotating seat to rotate accordingly, so that the lifting rod rotates synchronously. Subsequently, the fixing structure is driven to rotate by the lifting rod, and then the monitor is driven to rotate by the fixing structure. At the same time, when the lifting rod is started, the fixing structure moves up and down synchronously, realizing flexible adjustment of the height and angle of the monitor to ensure that they can always be in the best monitoring position.

[0066] 3. By setting the fixing plate, clamping plate, screw rod and fixing block, unscrew the fixing block to separate it from the screw rod, and then pull the clamping plate. Since one end of the clamping plate can rotate in the fixing plate, it will drive the screw rod to move out, and the disassembly and assembly of the monitor can be realized, thus facilitating subsequent maintenance work.

[0067] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description.
