Description

Technical Field

[0001] The utility model relates to the field of mine safety, in particular to the field of safety indicating devices, and specifically refers to a mine opening road traffic safety indicating device. Background Art

[0002] Coal is a solid combustible mineral that was gradually formed by ancient plants buried underground and undergoing complex biochemical and physicochemical changes. Coal is hailed as black gold and food for industry. At present and for a long time in the future, coal is still one of the indispensable sources of energy for our human production and life. The supply of coal is also related to the stability of the development of my country's industry and even the entire society. Most of the existing underground coal mining methods adopt the method of excavating tunnels, laying tracks in the tunnels, and using mining equipment trains to load coal into mine cars and transport them to the ground. The mine cars must intersect with other roads at the exit of the mine.

[0003] In the coal mining industry, the wellhead road is an important channel connecting the inside and outside of the mine. Its safety and traffic efficiency have a vital impact on the production operation of the mine and the personal safety of miners. Traditional minehead traffic control systems mostly use manual control or install traffic lights at intersections, relying mostly on drivers and pedestrians to judge the safety of intersections. Once pedestrians or drivers are distracted and not paying attention, traffic accidents will occur. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a wellhead road traffic safety indication device, which provides safe passage prompt information for drivers and pedestrians by real-time monitoring of the dynamics of vehicles and pedestrians in the wellhead area and the status of wellhead facilities, thereby reducing the risk of accidents.

[0005] The utility model is realized through the following technical scheme, which provides a wellhead road traffic safety indication device, including an infrared sensor installed at the wellhead, the infrared sensor is electrically connected to a central system, a deceleration mechanism electrically connected to the central system is installed on the track, a car blocker is installed on the right side of the deceleration mechanism, the car blocker is electrically connected to the central system, a plurality of detection devices are installed at the intersection of two roads, the plurality of detection devices are arranged around the intersection to form a detection area, the detection devices are electrically connected to the central system, moving doors are installed at the intersection of roads on both sides of the track, and the moving doors are electrically connected to the central system; the deceleration mechanism includes a slide rail extending along the track direction, a slide plate is slidably connected to the slide rail, a ground pier fixed on the ground is installed on the left side of the slide rail, the slide plate is connected to the ground pier through a spring, a baffle is hinged on the slide plate, and the baffle is driven to rotate by a rotating motor electrically connected to the central system.

[0006] The utility model senses whether there is a vehicle driving out of the wellhead by setting an infrared sensor, and the central system is responsible for collecting and processing information. The vehicle blocker can prevent the mine car from moving forward, the detection device can detect whether pedestrians are in the intersection area, and the movable door can be closed when the mine car passes through the intersection to prevent pedestrians from passing through. The deceleration mechanism can provide a deceleration effect on the mine car. When a mine car is driving but there are still people in the detection area of ​​the intersection, the detection device transmits a signal to the central system, and the central system controls the baffle to rotate so that the baffle is in a vertical state. If the mine car has inertia when decelerating, the baffle can have a certain deceleration effect on the mine car, giving pedestrians time to stay away from the detection area, thereby avoiding the occurrence of traffic accidents.

[0007] As an optimization, a vehicle camera display screen is set on one side of the mine car driving road, and a pedestrian camera display screen is set on one side of the pedestrian walking road. The vehicle camera display screen is electrically connected to the pedestrian camera display screen. With the setting of this optimization scheme, the mine car driver can observe the situation of the pedestrian road through the vehicle camera display screen, and the pedestrian can observe the situation of the track at the wellhead through the pedestrian camera display screen, so as to confirm each other and ensure the safety of pedestrians.

[0008] As an optimization, the detection device is electrically connected to an audible and visual alarm. In the setting of this optimization scheme, when the infrared sensor senses a vehicle and the detection device detects a pedestrian in the detection area, the audible and visual alarm at the intersection will emit a sound and red light alarm to warn the mine car driver and the passerby to quickly move away from the intersection.

[0009] As an optimization, a speed measuring mechanism is provided at the wellhead, and the speed measuring mechanism is electrically connected to an alarm mechanism. In the setting of this optimization scheme, the speed measuring mechanism can detect the speed of the mine car leaving the wellhead, and can also display the speed of the mine car. When the mine car speed is too fast, the alarm mechanism will alarm to warn the driver of the excessive speed.

[0010] As an optimization, the track height at the intersection is greater than the track height on both sides of the intersection. The setting of this optimization scheme can slow down the mine car traveling to the intersection and use the uphill slope to make the mine car pass the intersection slowly.

[0011] The beneficial effects of the utility model are as follows: from the perspective of economic benefits, on the one hand, the device can significantly improve the safety of traffic on the wellhead road, reduce the possibility of accidents, and thus reduce the economic losses caused thereby. On the other hand, the use of the device can reduce road damage and repair costs caused by accidents, and reduce maintenance costs. At the same time, the smooth flow of wellhead roads can ensure the rapid and safe passage of miners and materials, thereby improving production efficiency. From the perspective of social benefits, the device can improve the safety level of mine production, ensure the life safety of miners to a certain extent, reduce casualties and equipment damage caused by accidents, and avoid huge direct and indirect economic losses. At the same time, it accelerates the process of intelligent construction of mines, improves the social image and credibility of coal enterprises, and further expands their market influence.

The vehicle camera display screen 4 is electrically connected to the pedestrian camera display screen 5. There are two pedestrian camera display screens.

The pedestrian camera display screen is located on the right side of the pedestrian travel direction, and the vehicle camera display screen 4 is located on the left side of the vehicle travel direction. The two pedestrian camera display screens are electrically connected to the vehicle camera display screen 4. The pedestrian camera display screen and the vehicle camera display screen have camera and shooting functions.
