Description

Technical Field

[0001] This utility model relates to the field of underground mining vehicle technology, specifically an alarm device for underground mining vehicles. Background Technology

[0002] The UK-12 ore carrier is a trackless transport device specifically designed and manufactured for underground mines. It is primarily used in conjunction with loader cranes in underground tunneling and mining operations. Transporting ore and various materials significantly improves operational efficiency and is a crucial piece of equipment for achieving trackless mining operations.

[0003] However, current underground ore transport vehicles have the following problems: 1) During the journey, the narrow field of vision in the mine, coupled with the high dust levels, obstructs the view when there are people ahead or at bends, making travel difficult; 2) The critical lighting equipment lacks protective features, and falling rocks or dust can damage it. Therefore, we propose an alarm device for underground ore transport vehicles. Utility Model Content

[0004] The purpose of this invention is to solve the problems of obstructed vision leading to difficulty in movement and easy damage to lighting equipment, and to provide an alarm device for underground mining vehicles.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An alarm device for underground mining vehicles includes a vehicle undercarriage. A vehicle front is fixedly mounted on the top of the front of the vehicle undercarriage, and a driver's cab is fixedly mounted on the top of the back of the vehicle undercarriage. An alarm device is installed on the top of the vehicle front. The alarm device includes a millimeter-wave radar, a radar dome, a wire, a light pole, and a buzzer. The millimeter-wave radar is fixedly mounted on the inner wall of the front of the vehicle front. The radar dome is fixedly mounted on the output end of the millimeter-wave radar. One end of the wire is fixedly mounted on the outer wall of the millimeter-wave radar. The light pole is fixedly mounted on the other end of the wire and is also fixedly mounted on the top of the vehicle front. The buzzer is fixedly mounted on the top of the light pole.

[0007] Preferably, the alarm device further includes a transparent cover, an outer sleeve, an inner sleeve, a protective cover, a spring, a connecting rod, and a scraper ring. The transparent cover is fixedly installed on the top of the front of the vehicle near the light pole. The outer sleeve is fixedly installed on the top of the transparent cover. The inner sleeve is slidably installed on the inner wall of the outer sleeve. The protective cover is fixedly installed on the top of the inner sleeve. The spring is disposed between the transparent cover and the protective cover. The connecting rod is fixedly installed on the bottom of the protective cover. The scraper ring is fixedly installed on the outer wall of the connecting rod near the transparent cover.

[0008] Preferably, the outer wall of the outer sleeve has a through hole at the bottom end, the protective cover is conical, and the inner wall of the scraper ring is in contact with the outer wall of the transparent cover.

[0009] By employing the above technical solution, this utility model provides an alarm device for underground mining vehicles. It possesses at least the following beneficial effects:

[0010] (1) By setting up a millimeter-wave radar, when there are people or corners in front, the radar dome senses the obstacles in front and transmits the electrical signal to the processing unit inside the millimeter-wave radar. The processing unit then transmits the alarm trigger signal to the light pole through the wire. The light pole and the buzzer will flash and sound at the same time. Even if the driver cannot see the potential dangers of people or corners in the dusty environment, the millimeter-wave radar can still "see" them and transmit the danger signal to the light pole and the buzzer through the wire, issue an alarm in time, and remind the driver to take measures to avoid accidents.

[0011] (2) This utility model can effectively protect the lamp post and buzzer by setting a transparent cover, thus avoiding dust intrusion. When a rock falls on the transparent cover, the conical protective cover will block the rock. When the rock impacts, the conical protective cover will disperse and guide the impact force outward through its inclined structure, preventing the rock from directly impacting the transparent cover. The inner sleeve slides down the inner wall of the outer sleeve under the impact force, and the spring further buffers the impact force and absorbs the impact energy. The protective cover also drives the connecting rod to move downward, and the connecting rod drives the scraper ring to move downward. The scraper ring scrapes off the dust attached to the outer wall of the transparent cover, maintains the light transmittance of the cover, ensures the lighting brightness of the internal lamp post, and ensures that the alarm signal is continuously and effectively transmitted in the dusty environment.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0019] An alarm device for underground mining vehicles, such as Figures 1-3 As shown, the vehicle includes a chassis 1, a cab 11 fixedly mounted on the top of the front of the chassis 1, and a driver's cab 12 fixedly mounted on the top of the back of the chassis 1. An alarm device 2 is installed on the top of the cab 11. The alarm device 2 includes a millimeter-wave radar 21, a radar dome 22, a wire 23, a light pole 24, and a buzzer 25. The millimeter-wave radar 21 is fixedly mounted on the inner wall of the front of the cab 11. The radar dome 22 is fixedly mounted on the output end of the millimeter-wave radar 21. One end of the wire 23 is fixedly mounted on the outer wall of the millimeter-wave radar 21. The light pole 24 is fixedly mounted on the other end of the wire 23 and is fixedly mounted on the top of the cab 11. The buzzer 25 is fixedly mounted on the top of the light pole 24.

[0020] This utility model discloses an alarm device for underground mining vehicles. When operators drive mining vehicles underground, dust often rises during the vehicle's movement, reducing the driver's visibility. This can lead to accidents or injuries if someone is passing by or the vehicle is turning. The millimeter-wave radar 21 detects obstacles ahead (such as people or corners) via the radar dome 22 and transmits an electrical signal to the processing unit inside the millimeter-wave radar 21. The processing unit then transmits an alarm trigger signal via wire 23 to the light pole 24. The light pole 24 and buzzer 25 simultaneously flash and sound. Even if the driver cannot see potential dangers ahead or around corners in a dusty environment, the millimeter-wave radar 21 can still "see" them and transmit the danger signal to the light pole 24 and buzzer 25 via wire 23, issuing a timely alarm and reminding the driver to take measures to avoid accidents. Example

[0021] This embodiment, based on embodiment 1, specifically includes the following:

[0022] like Figure 4As shown, the alarm device 2 also includes a transparent cover 26, an outer sleeve 27, an inner sleeve 28, a protective cover 29, a spring 210, a connecting rod 211, and a scraper ring 212. The transparent cover 26 is fixedly installed on the top of the front of the vehicle 11 near the light pole 24. The outer sleeve 27 is fixedly installed on the top of the transparent cover 26. The inner sleeve 28 is slidably installed on the inner wall of the outer sleeve 27. The protective cover 29 is fixedly installed on the top of the inner sleeve 28. The spring 210 is disposed between the transparent cover 26 and the protective cover 29. The connecting rod 211 is fixedly installed on the bottom of the protective cover 29. The scraper ring 212 is fixedly installed on the outer wall of the connecting rod 211 near the transparent cover 26.

[0023] The outer wall of the outer sleeve 27 has a through hole at the bottom end, the protective cover 29 is tapered, and the inner wall of the scraper ring 212 is in contact with the outer wall of the transparent cover 26.

[0024] This utility model discloses an alarm device for underground mining vehicles. When the driver is driving the mining vehicle through the mine shaft, dust will be stirred up, and the vibration from the vehicle can cause rocks to fall from the mine roof. The transparent cover 26 effectively protects the light pole 24 and the buzzer 25 from dust. When a rock falls towards the transparent cover 26, the conical protective cover 29 blocks it. Upon impact, the conical protective cover 29, through its inclined structure, disperses and guides the impact force outwards, preventing the rock from directly impacting the transparent cover 26. When the inner sleeve 28 is impacted, it slides downward on the inner wall of the outer sleeve 27. The through hole of the outer sleeve 27 releases the internal gas that is squeezed downward by the inner sleeve 28. In conjunction with the spring 210, the impact force is further buffered and the impact energy is absorbed. The protective cover 29 also drives the connecting rod 211 to move downward. The connecting rod 211 drives the scraper ring 212 to move downward. The scraper ring 212 scrapes off the dust attached to the outer wall of the transparent cover 26, maintains the light transmittance of the cover, ensures the lighting brightness of the internal light pole 24, and ensures that the alarm signal is continuously and effectively transmitted in the dusty environment.
