[0002] Due to the tight construction period requirements for extra-long highway tunnels, inclined shafts are often driven during design to increase the working face, speed up the construction progress, and solve the needs of transportation, ventilation, drainage, and waste disposal in the main tunnel of the tunnel. Restricted by terrain and geological conditions, many tunnel constructions have long inclined shafts. When transporting materials in a long inclined shaft, trackless vehicles will experience a long downhill journey, which poses a huge test to the braking system of the transport vehicle, increasing the possibility of traffic accidents occurring in the inclined shaft due to failures in the vehicle braking system. In order to ensure the safe progress of production activities in the inclined shaft, a solution that can control the safe driving of vehicles in the inclined shaft and can take evasive action when the vehicle braking fails is needed, so as to avoid traffic accidents and reduce the losses caused by accidents. Summary of the Invention

[0004] The technical solution adopted to solve the above technical problem is: a safety control system for trackless transportation in inclined shafts, including an inclined shaft lane and an escape lane. The inclined shaft lane is composed of an uphill lane and a downhill lane. An uphill warning light strip is arranged on one side of the uphill lane, and a downhill warning light strip is arranged on one side of the downhill lane.

[0005] The escape lane is an uphill lane. A number of anti-rolling devices are arranged along the slope trend on the escape lane. A safety indicator light is arranged at the entrance of the escape lane, and a microwave probe is arranged at the end;

[0006] A trackless transportation safety control platform is used to receive information from the pan-tilt camera, sound level meter, millimeter-wave radar, and microwave probe, and connect to the safety indicator light and in-vehicle real-time intercom for staff to issue corresponding instructions.

[0007] The anti-rolling device of the present utility model is as follows: There are grooves provided on the escape lane, movable wheel stops are arranged in the grooves, a driving member for driving the opening and closing of the movable wheel stops is arranged between the grooves and the movable wheel stops, the movable wheel stops are rotatably arranged on the side wall of the groove through a rotating shaft, a connecting rod is rotatably arranged on one side of the movable wheel stop, the other end of the connecting rod is fixed to the left end of the groove, a slider is arranged on the connecting rod, the slider is connected with a support rod, and one end of the support rod is connected with the movable wheel stop through a connecting member.

[0008] The driving member of the present utility model includes a controller, a pressure sensor, and a magnetic member. The magnetic member includes an electromagnetic device and a magnet. The electromagnetic device is installed in the bottom groove and is connected to the controller. The magnet is installed on the lower side surface of the movable wheel stop and is magnetically connected to the magnetic device. The pressure sensor is installed on the movable wheel stop for collecting pressure information on the escape lane and transmitting the collected pressure information to the controller.

[0022] The present utility model will be further described in detail below with reference to the drawings and embodiments, but the present utility model is not limited to these embodiments.

[0023] Embodiment 1

[0024] In Figure 1Among them, a safety control system for trackless transportation in inclined shafts of the present utility model includes an inclined shaft lane 1 and an escape lane 10. The inclined shaft lane 1 is composed of an uphill lane and a downhill lane. An uphill warning light strip 5 is arranged on one side of the uphill lane, and a downhill warning light strip 4 is arranged on one side of the downhill lane. Sound level meters 2, pan-tilt cameras 3, uphill warning boards 7, and downhill warning boards 8 are arranged at intervals on the side wall of the inclined shaft lane 1. A millimeter-wave radar 11 is arranged on the arch top above the inclined shaft lane 1, and an in-vehicle real-time intercom 6 is arranged on the running vehicle. When the driver continuously presses the car horn for an out-of-control vehicle, the sound level meter 2 picks up the out-of-control information, which can reflect whether the vehicle speed of the passing vehicles in the inclined shaft is out of control. The pan-tilt camera 3 is used to monitor the running position and state of the vehicles in the inclined shaft in real time. The warning light strips are arranged longitudinally along the inclined shaft. When the vehicle is not speeding, they are displayed in white. When the vehicle is speeding, they are displayed in red and blink. The warning boards can cooperate with the millimeter-wave radar 11 to display the vehicle speed and the number of vehicles in the front driving section. When the millimeter-wave radar 11 detects that the vehicle is out of control, the warning board will display that there is an out-of-control vehicle in the uphill lane or the downhill lane of the inclined shaft, reminding vehicles not to drive on the lane on this side of the inclined shaft. Further, a millimeter-wave radar 11 can be arranged on the arch top directly opposite to the escape lane 10 to monitor the driving speed of the vehicles driving into the escape lane 10.

[0025] The escape lane 10 is an uphill lane. A number of anti-rolling devices 14 and collision buffer devices are arranged along the slope trend on the escape lane 10. The anti-rolling devices 14 are used to prevent the risk of rolling back of the vehicles rushing onto the escape lane 10. A safety indicator light 13 is arranged at the entrance of the escape lane 10, and a microwave probe 12 is arranged at the end. When the safety indicator light 13 is displayed in red, it means that the escape lane 10 is occupied. The microwave probe 12 is used to detect whether there are vehicles occupying the escape lane 10. At the same time, the microwave probe 2 can detect the movement state of the vehicle. If it detects that the vehicle is in a position driving towards the exit, at this time, it cooperates to make the safety indicator light blink, reminding the vehicles within a range of 500 meters behind the escape lane 10 to pay attention to decelerating, and there is a vehicle merging into the escape lane 10 ahead, which can avoid side collision.

[0026] The trackless transportation safety control platform is used to receive the information of the pan-tilt camera 3, the sound level meter 2, the millimeter-wave radar 11, and the microwave probe 12, and is connected to the safety indicator light 13 and the in-vehicle real-time intercom 6 for the staff to view the speed and position information of the vehicles and transmit voice information. The sound level meter 2, the downhill lane warning board 7, the uphill lane warning board 8, the downhill warning light strip 4, the uphill warning light strip 5, the microwave probe 12, the pan-tilt camera 3, and the safety indicator light 13 are comprehensively controlled by a PLC controller. The PLC controller communicates with the trackless transportation safety control platform.

[0027] In Figure 2 、 3In this case, the anti-rolling device 14 of the utility model is composed of a slider 14-1, a support rod 14-2, a connecting piece 14-3, a pressure sensor 14-4, a movable wheel stopper 14-5, a magnetic part 14-6, a rotating shaft 14-7, a connecting rod 14-8, and a baffle 14-9. A groove 10-1 is provided on the escape lane 10, and a movable wheel stopper 14-5 is arranged in the groove 10-1. A driving part for driving the opening and closing of the movable wheel stopper 14-5 is arranged between the groove 10-1 and the movable wheel stopper 14-5. The movable wheel stopper 14-5 is rotatably arranged on the side wall of the groove 10-1 through the rotating shaft 14-7. A connecting rod 14-8 is rotatably arranged on one side of the movable wheel stopper 14-5, and the other end of the connecting rod 14-8 is fixed to the left end of the groove 10-1. A slider 14-1 is arranged on the connecting rod 14-8, and the slider 14-1 is connected to the support rod 14-2. One end of the support rod 14-2 is connected to the movable wheel stopper 14-5 through the connecting piece 14-3. The driving part drives the movable wheel stopper 14-5 to rotate counterclockwise along the rotating shaft 14-7. When the slider 14-1 slides to the leftmost end of the groove 10-1, the movable wheel stopper 14-5 is exactly in the vertical position, and the support rod 14-2 plays a supporting role to prevent the movable wheel stopper 14-5 from continuing to rotate counterclockwise, thus playing a role in preventing the vehicle from rolling. A baffle 14-9 is arranged at one end of the slider 14-1, and the baffle 14-9 can slide in the chute 10-2 as the slider 14-1 slides. An installation groove 14-5-1 is machined on the side surface of the movable wheel stopper 14-5, and the support rod 14-2 is rotatably connected between the connecting piece 14-3 and the slider 14-1. When the movable wheel stopper 14-5 rotates to be flush with the slope of the escape lane 10, the support rod 14-2 also moves to be flush with the movable wheel stopper 14-5. The support rod 14-2 and the baffle 14-9 completely block the slope gap, preventing road debris from falling into it, and thus affecting the movement of the slider 14-1 on the connecting rod 14-8.

[0028] Furthermore, the driving component of this embodiment includes a controller, a pressure sensor 14-4, and a magnetic component. The magnetic component includes an electromagnetic device 14-6 and a magnet. Among them, the electromagnetic device 14-6 is installed in the bottom groove 10-1 and is connected to the controller; the magnet is installed on the lower side of the movable wheel stopper 14-5 and is magnetically connected to the magnetic device. The pressure sensor is installed on the movable wheel stopper 14-5 and is used to collect the pressure information on the escape lane 10 and transmit the collected pressure information to the controller. The controller is used to compare the received pressure information with a preset threshold and control the start and stop of the magnetic component 14-6 according to the comparison result. When a vehicle drives in, first, the vehicle will rush to the high point along the bottom of the escape lane 10. During this process, a large amount of impact energy will be absorbed, thereby reducing the speed of the vehicle. During this process, the tires of the vehicle will press over the movable wheel stopper 14-5. When the pressure sensor 14-4 in the movable wheel stopper 14-5 reaches the threshold, the electromagnetic device changes the direction of the current, thereby changing the magnetic pole of the electromagnet. At this time, the magnet in the movable wheel stopper 14-5 drives the movable wheel stopper 14-5 to move to the upright state under the action of the magnetic force.

[0029] The working principle of the present utility model is as follows:

[0030] The millimeter-wave radars 11 are arranged at intervals, and the section between two adjacent millimeter-wave radars 11 is divided into a driving section. The sound level meter 2 will pick up the horn information of the lane dump truck. Once the limit value is exceeded, the light strip in the driving section starts to change from white to red and flashes continuously. At this time, the light strips in other sections still remain in the original state, reminding the vehicle driver to slow down. When the vehicle passes the next millimeter-wave radar 11, the millimeter-wave radar 11 will continue to measure the speed of the vehicle. When the vehicle speed measured by the next speedometer is less than the limit value, the vehicle is in a safe driving state, and the light strip in the driving section changes from the red flashing state to the white lighting state; if the vehicle speed measured is not lower than the limit value or even greater than the vehicle speed measured at the previous speed measurement node, it is determined that the vehicle is in an out-of-control state. At this time, the light strips in all driving sections become red and flash, and at the same time, the monitoring room personnel receive the alarm sent by the millimeter-wave radar 11, lock the position of the out-of-control vehicle according to the monitoring, and conduct emergency command on the out-of-control vehicle through the on-vehicle real-time intercom 6, directing the vehicle to drive into the emergency escape lane 10. The vehicle driving into the escape lane 10 triggers the anti-rolling device 14. At the same time, the light strip on the other side will change to a yellow flashing state, reminding the vehicles in this lane to park tightly against the side to avoid colliding with the out-of-control vehicle. The information warning board shows the number of vehicles in the section. When there are too many vehicles, it will remind the driver to slow down. When the vehicle is out of control, the information warning board on this side will display the red font "Danger, No Entry!" and the warning board on the other side will display the red font "Danger, Pull Over Immediately!".
