[0041] In an embodiment of the present application, after the locomotive stops moving, the iron shoe 1 is taken out from the placement cavity 21 of the placement rack 2 and placed on the track, and the wheels of the locomotive are limited to prevent the locomotive from slipping. When the locomotive starts, the control module will receive a start signal; after the iron shoe 1 is put away from the track and placed in the placement cavity 21, the proximity sensor can sense the iron shoe 1. At this time, the proximity sensor transmits a detection signal to the control module, indicating that the iron shoe 1 has been collected and can be started, so the sound and light alarm will not sound an alarm. When the control module receives the start signal and does not receive the detection signal of the proximity sensor, it means that the iron shoe 1 on the track has not been put away. At this time, the control module controls the sound and light alarm on the center console to sound an alarm, reminding the driver and passengers to take away the iron shoe 1 on the track to prevent the locomotive from falling off the track. It should be noted that the proximity sensor and the sound and light alarm light are prior art and will not be repeated here.

[0042] Compared with the prior art, the locomotive iron shoe suspension alarm assembly provided by the present invention senses the iron shoe 1 in the placement cavity 21 through a proximity sensor, so that when the locomotive is started, the control module can determine whether to remove the iron shoe 1 on the track; when the iron shoe 1 on the track is not removed, the driver and passengers are reminded to remove the iron shoe 1 on the track, thereby reducing the occurrence of locomotive derailment and facilitating the reduction of safety hazards.

[0043] In addition, the iron shoe 1 comprises a head 11 and a sole 12, the head 11 has an inclined surface suitable for contacting a locomotive wheel, and the sole 12 is a plate-shaped structure.

[0044] In some embodiments, Figures 1 to 8 As shown, the bottom wall of the placement cavity 21 has a first through hole 22 suitable for the sole 12 of the iron shoe 1 to pass through, and the outer wall of the placement frame 2 has a limiting hole 23 suitable for communicating with the placement cavity 21, and the limiting hole 23 is close to the opening end of the placement cavity 21; the locking mechanism 3 includes a sealing plate 31 and a blocking portion 32; the top of the sealing plate 31 is hinged to the top of the opening end of the placement cavity 21 through a rotating shaft; the sealing plate 31 has an extension plate 33 at the rotating shaft, and the extension plate 33 is suitable for contacting with the iron shoe 1, and under the drive of the iron shoe 1, the rotating shaft rotates around its axis, so that The sealing plate 31 closes the opening of the placement cavity 21; the blocking part 32 is slidably arranged in the limiting hole 23; the blocking part 32 is suitable for contacting the side of the iron shoe 1 close to the opening of the placement cavity 21 to limit the iron shoe 1 in the placement cavity 21; wherein, a first elastic member (not shown in the figure) is provided at the rotating shaft of the sealing plate 31, and the first elastic member is suitable for providing torque to the rotating shaft so that the sealing plate 31 opens the opening of the placement cavity 21; a second elastic member 34 is provided on the blocking part 32, and the second elastic member 34 is suitable for making one end of the blocking part 32 slide into the placement cavity 21.

[0045] Exemplarily, the first elastic member is a torsion spring, which is sleeved on the rotating shaft of the closing plate 31, one end of which is fixed to the placement rack 2, and the other end of which is fixed to the rotating shaft. When the head 11 of the iron shoe 1 contacts the extension plate 33 and continues to slide into the placement cavity 21, the extension plate 33 and the closing plate 31 both rotate along the rotating shaft, thereby enabling the closing plate 31 to close the opening of the placement cavity 21. In addition, the top of the placement rack 2 has an escape space suitable for the extension plate 33 to rotate around the rotating shaft.

[0046] Exemplarily, the second elastic member 34 is a spring, which is sleeved on the blocking portion 32, one end of the spring is fixed on the placement frame 2, and the other end of the spring is fixed on the blocking portion 32. After the iron shoe 1 is installed in place, the inner end of the blocking portion 32 extends into the placement cavity 21 under the elastic force of the spring, and can limit the side of the iron shoe 1 close to the opening of the placement cavity 21 to prevent the iron shoe 1 from slipping out of the opening of the placement cavity 21. Through the cooperation of the blocking portion 32 and the sealing plate 31, the iron shoe 1 can be limited in the placement cavity 21, and the opening of the placement cavity 21 can be closed; during the movement of the locomotive, the amount of debris entering the placement cavity 21 can be reduced, thereby reducing the impact of the debris on the iron shoe 1.

[0047] In some embodiments, Figures 1 to 8As shown, both sides of the head 11 of the iron shoe 1 have a downwardly bent portion 13, and the bent portion 13 is suitable for contacting with both sides of the track; the lower surface of the placement cavity 21 has a slide groove 24 suitable for sliding cooperation with the bent portion 13; when the iron shoe 1 is plugged into place, the end of the bent portion 13 contacts the end of the slide groove 24, and the blocking portion 32 contacts the side of the iron shoe 1 close to the opening of the placement cavity 21 to limit the hanging position of the iron shoe 1. The top of the placement cavity 21 is suitable for contacting with the top of the iron shoe 1 to limit the height of the iron shoe 1. The length of the closing plate 31 is greater than the opening length of the placement cavity 21. When the closing plate 31 closes the opening of the placement cavity 21, the closing plate 31 contacts the opening end of the placement cavity 21.

[0048] Exemplarily, by the top of the iron shoe 1 contacting the top of the placement cavity 21, the iron shoe 1 can be limited in height to reduce the sliding of the iron shoe 1 in the height direction. After the iron shoe 1 slides into place, the bent portion 13 on the iron shoe 1 contacts the end of the slide groove 24, so the position of the iron shoe 1 in the placement cavity 21 can be limited. After the bent portion 13 contacts the end of the slide groove 24, the blocking portion 32 contacts the side of the iron shoe 1 close to the opening of the placement cavity 21; through the cooperation of the end of the slide groove 24 and the bent portion 13, the iron shoe 1 can be limited in the horizontal direction.

[0049] It should be noted that the iron shoe 1 contacts the two sides of the rail respectively through the two bending parts 13, and can limit the iron shoe 1 in the direction perpendicular to the rail. Therefore, it can strengthen the connection between the iron shoe 1 and the rail, making it easier for the iron shoe 1 to limit the locomotive wheel and reduce the occurrence of slipping.

[0050] In some embodiments, Figures 1 to 8 As shown, the other end of the blocking portion 32 extends to the outside of the placement rack 2, and a fixing portion 25 is fixedly provided on the outside of the placement rack 2 at the position of the blocking portion 32, and a threaded hole is provided on the fixing portion 25, and a through hole suitable for aligning with the threaded hole is provided on the blocking portion 32; wherein, after the iron shoe 1 is installed in place, the inner end of the blocking portion 32 contacts the iron shoe 1, and the through hole on the blocking portion 32 is aligned with the threaded hole on the fixing portion 25; a bolt 26 is provided at the threaded hole, and one end of the bolt 26 is plugged into and matched with the through hole of the blocking portion 32.

[0051] It should be noted that after the iron shoe 1 is installed in the placement cavity 21, the blocking portion 32 limits the iron shoe 1, which can reduce the situation where the iron shoe 1 slides out of the placement cavity 21. When the blocking portion 32 limits the iron shoe 1, the through hole at the outer end of the blocking portion 32 is aligned with the threaded hole on the fixing portion 25. At this time, the bolt 26 is threadedly matched with the fixing portion 25, and one end of the bolt 26 is inserted into the through hole of the blocking portion 32, which can limit the sliding of the blocking portion 32 in the limiting hole 23; during the driving process of the locomotive, the stability of the blocking portion 32 can be improved.

[0052] In some embodiments, Figures 1 to 8 As shown, the inner end of the blocking portion 32 has a threaded hole, and the sealing plate 31 has a through hole aligned with the threaded hole; the sealing plate 31 is also provided with a bolt 26 suitable for passing through the through hole of the sealing plate 31 and threadedly matching with the threaded hole of the blocking portion 32.

[0053] Exemplarily, after the iron shoe 1 is installed in the placement cavity 21, the bolt 26 passes through the through hole on the sealing plate 31 and is threadedly engaged with the threaded hole of the blocking part 32, thereby strengthening the connection between the sealing plate 31 and the blocking part 32; during the running of the locomotive, the situation where the sealing plate 31 opens the opening of the placement cavity 21 can be reduced.

[0054] In some embodiments, Figures 1 to 8 As shown, the outer wall of the placement rack 2 has a stretching drive structure 4 at the position of the first through hole 22 of the placement cavity 21. The stretching drive structure 4 is suitable for clamping the protruding portion of the sole 12 of the iron shoe 1 and for driving the sole 12 of the iron shoe 1 to slide outward. The stretching drive structure 4 includes a driving member 41 and a clamp 42; the driving member 41 is fixed on the outer wall of the placement rack 2; the clamp 42 is fixed on the telescopic end of the driving member 41, and the clamp 42 is suitable for clamping the protruding portion of the sole 12 of the iron shoe 1. The protruding portion of the sole 12 of the iron shoe 1 has a connecting hole 14, and the clamp 42 has a connecting column 43 suitable for plugging and matching with the connecting hole 14.

[0055] Exemplarily, when the sole 12 of the iron shoe 1 passes through the first through hole 22, the protruding part of the sole 12 is clamped by the clamp 42; during the clamping process, the connecting column 43 on the clamp 42 is plugged into the connecting hole 14 on the iron shoe 1, so that the connection between the clamp 42 and the iron shoe 1 can be strengthened. The driving member 41 can be a cylinder, and the clamp 42 is fixed on the piston rod of the cylinder; after the clamp 42 clamps the sole 12, the piston rod of the cylinder extends, which can drive the sole 12 to slide outward, and then the head 11 of the iron shoe 1 slides to the designated position of the placement cavity 21, and the blocking part 32 is used to limit the iron shoe 1 in the horizontal direction, and the sealing plate 31 closes the opening of the placement cavity 21. Through the above arrangement, the iron shoe 1 can be stably placed in the placement cavity 21, and the loss of the iron shoe 1 can be reduced during the driving of the locomotive.

[0056] 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.
