Description

Technical Field

[0001] The utility model relates to the technical field of railway diesel locomotives, in particular to a protective device. Background Art

[0002] A railway diesel locomotive refers to a train vehicle that uses an internal combustion engine as a power source and runs on railways. It is used to transport goods and passengers. In addition to protecting the locomotive itself, it is also necessary to protect the environment around the locomotive and the safety of pedestrians.

[0003] When an existing diesel locomotive passes a road crossing on a track, the protective devices at the road crossing mostly use fences to block pedestrians. Since the fences are low, the protective devices are easily crossed by people and small animals, which may cause accidents and make it easy for pedestrians and small animals to cross the protective devices, thus endangering the safety of diesel locomotives, pedestrians and small animals.

[0010] By adopting the above technical solution and starting the electric telescopic rod, the limit plate can slide along the inner wall of the fixed shell, so that the outer surface of the limit plate and the outer surface of the limit block fit together, which is convenient for limiting the limit block.

[0011] As a preferred solution of the protective device described in the utility model, the other end of the baffle rod is slidably connected to a support column, and the upper surface of the baffle rod is fixedly connected to a cooling fan and a second motor, the outer surface of the cooling fan is fixedly connected to the inner wall of the connecting shell, and the output shaft of the second motor passes through the outer surface of the connecting shell and is fixedly connected to the outer surface of the rotating rod.

[0016] By adopting the above technical solution, a buzzer emits a sound, which is convenient for warning people or animals near the barrier.

[0017] The utility model provides a protective device having the following beneficial effects:

[0018] 1. By starting the second motor, the output shaft of the second motor drives the rotating rod to rotate, and the rotation of the rotating rod drives the flashing light to rotate, so that the outer surface of the barrier rod forms a circular protection range.

[0028] The specific blocking mechanism 3 also includes a fixed plate 306 fixedly connected to the inner wall of the fixed shell 1, and the upper surface of the fixed plate 306 is fixedly connected to the first motor 307, and the output shaft of the first motor 307 passes through the outer surface of the fixed shell 1 and is fixedly connected to the outer surface of the blocking rod 309, wherein the blocking rod 309 and the rotating rod 303 are made of carbon fiber material, and the carbon fiber has extremely high strength and rigidity, and is light in weight, wherein the output shaft of the first motor 307 is fixedly connected to the limiting block 312, and the lower surface of the limiting block 312 is in contact with the limiting plate 310, and the lower surface of the limiting plate 310 is fixedly connected to the limiting plate 310. The surface is fixedly connected with the output end of the electric telescopic rod 308, the electric telescopic rod 308 is fixedly connected to the inner wall of the fixed shell 1, the other end of the blocking rod 309 is slidably connected to the support column 305, and the upper surface of the blocking rod 309 is fixedly connected with the cooling fan 302 and the second motor 311, the outer surface of the cooling fan 302 is fixedly connected to the inner wall of the connecting shell 301, and the output shaft of the second motor 311 passes through the outer surface of the connecting shell 301 and is fixedly connected to the outer surface of the rotating rod 303, and the outer surfaces of the connecting shell 301 and the fixed shell 1 are provided with heat dissipation holes.

[0029] The second motor 311 is further started, and the output shaft of the second motor 311 drives the rotating rod 303 to rotate, and the rotation of the rotating rod 303 drives the flashing light 201 to rotate, so that the outer surface of the blocking rod 309 forms a circular protection range. Since there is no force point on the outer surface of the blocking rod 309 that is easy to grasp, it is not convenient for passers-by to climb. Example

[0030] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment. The warning mechanism 2 includes a flashing light 201 fixedly connected to the outer surface of the rotating rod 303, and the flashing light 201 is electrically connected to the display controller 202 through a wire, and the display controller 202 is fixedly connected to the outer surface of the fixed shell 1.

[0032] Furthermore, when a passerby tries to pass through the barrier bar 309, the infrared receiver 204 and the infrared transmitter 203 will be blocked. At this time, the infrared rays will be blocked, so that the infrared receiver 204 cannot receive the infrared rays.

When the rotating rod 303 rotates, it is not convenient for passers-by to climb because there is no force point for easy grasping. When passers-by try to pass through the barrier bar 309, it will block the infrared receiver 204 and the infrared transmitter 203. At this time, the infrared rays are blocked, causing the infrared receiver 204 to fail to receive the infrared rays. The infrared receiver 204 feeds back to the display controller 202 that the infrared signal is abnormal. At this time, the display controller 202 increases the volume of the buzzer 205 to facilitate the removal of passers-by and small animals.
