Description

Technical Field

[0001] The present application relates to the field of tunnel monitoring equipment, and in particular to a highway tunnel monitoring system. Background Art

[0002] Highway tunnels are passages exclusively for motor vehicle transportation. With the development of social economy and production, a large number of highways have emerged, putting forward higher standards for road construction technology, requiring straight routes, gentle slopes, wide road surfaces, etc. Therefore, when the road passes through mountains, the past plan of winding around the mountain has mostly been changed to a tunnel plan. The ancillary buildings of the tunnel include waterproof and drainage facilities, ventilation and lighting settings, traffic signal settings, and emergency facilities. At the same time, tunnel monitoring devices are generally installed in the tunnel, and the monitoring devices record the road conditions in the tunnel, as well as the driving conditions and violations of vehicles in the tunnel.

[0003] The existing Chinese patent with the authorized announcement number CN213152225U discloses a highway tunnel monitoring system, which specifically discloses a main controller, a plurality of support frames installed on the top of the tunnel, and cameras and positioning lights installed at the lower end of the support frames. A distance sensor is installed on the positioning light. When a tunnel collapse occurs, the distance sensor sends a signal to the main controller, and the main controller transmits the signal to the control room terminal.

[0004] In view of the above related technologies, the cameras and lights are fixedly installed on the top of the tunnel through support frames. When the cameras and lights need to be maintained and replaced, operators need to climb to the top of the tunnel through tools such as engineering ladders, and at this time, the normal passage of the highway tunnel will be affected. Summary of the Invention

[0005] In order to improve the problem that the normal passage of the tunnel will be affected when maintaining and replacing the cameras and lights on the top of the tunnel, the present application provides a highway tunnel monitoring system.

[0006] The highway tunnel monitoring system provided by the present application adopts the following technical solutions:

[0007] A highway tunnel monitoring system includes cameras and lighting fixtures installed on the top of the tunnel. An arched guide rail and an arched support frame parallel to the guide rail are arranged in the tunnel. A rail vehicle travels along the guide rail on the guide rail. A first slide rail is arranged on the lower surface of the rail vehicle. A mounting seat is arranged on the rail vehicle. A first chute adapted to the first slide rail is provided on the mounting seat. The camera or the lighting fixture is arranged on the mounting seat. A plurality of mounting platforms are arranged on the support frame. A second slide rail is arranged on the lower surface of the mounting platform opposite to the first slide rail. A moving component is further arranged on the rail vehicle. The moving component is used to drive the mounting seat to move between the first slide rail and the second slide rail. A fixing component is arranged on the mounting platform. The fixing component is used to fix the mounting seat on the mounting platform. A dismounting component is arranged on the rail vehicle. The dismounting component is used to remove the mounting seat from the mounting platform.

[0008] By adopting the above technical solutions, a plurality of mounting platforms are installed on the support frame. The rail vehicle moves to face one of the mounting platforms. The moving component is used to move the mounting seat to the mounting platform, and the fixing component is used to fix the mounting seat on the mounting platform. When removing the mounting seat, the dismounting component removes the mounting seat from the mounting platform, and the moving component moves the mounting seat to the rail vehicle. Thus, it is convenient to install or remove the camera or the lighting fixture from the top of the tunnel without using tools such as engineering ladders, and thus the normal traffic of the highway will not be affected.

[0009] Optionally, the moving component includes a first rodless electric cylinder and a moving plate. The moving plate is slidably arranged on the first slide rail. The first rodless electric cylinder is arranged on the moving plate and is parallel to the first slide rail. The slide table of the first rodless electric cylinder is connected to the moving plate.

[0010] By adopting the above technical solutions, the slide table of the first rodless electric cylinder drives the moving plate to move, so as to conveniently drive the mounting platform to move along the first slide rail at the bottom of the rail vehicle.

[0011] Optionally, an electromagnet is arranged on the side of the moving plate facing the rail vehicle.

[0012] By adopting the above technical solutions, the electromagnet generates an adsorption force on the mounting seat, so as to conveniently drive the moving plate to drive the mounting seat to move from the mounting platform to the rail vehicle.

[0013] Optionally, a baffle is provided on the side of the mounting table facing away from the guide rail. The fixing component includes a rotating plate and a tension spring. A receiving groove is formed on the lower surface of the mounting table. One end of the rotating plate is rotatably arranged on the mounting table and located in the receiving groove, and the other end extends outside the mounting table. A pressing groove for receiving the rotating plate is formed on the mounting seat. The receiving groove communicates with the pressing groove. One end of the tension spring is connected to the rotating plate, and the other end is connected to the mounting table. The tension spring makes the lower end of the rotating plate always tend to rotate towards the baffle.

[0014] By adopting the above technical solution, after the mounting seat moves to the mounting table, the rotating plate rotates under the action of the tension spring and abuts against the side wall of the pressing groove, thereby clamping the mounting seat between the baffle and the rotating plate, achieving the effect of facilitating the fixing of the mounting seat on the mounting table.

[0015] Optionally, the side wall of the pressing groove facing the guide rail is arranged in an arc shape, and the opening of the arc shape faces upward.

[0016] By adopting the above technical solution, the side wall of the pressing groove facing the guide rail is arranged in an arc shape, which facilitates the rotation of the rotating plate into or out of the mounting seat.

[0017] Optionally, a positioning groove is formed in the rail vehicle. The dismounting component includes a second rodless electric cylinder and a positioning rod. The second rodless electric cylinder is arranged on the rail vehicle and located in the positioning groove. The positioning rod is arranged on the slide table of the second rodless electric cylinder. The positioning rod extends towards the support frame. A positioning hole is formed on the mounting table. The positioning rod extends into the mounting table through the positioning hole. The positioning hole communicates with the receiving groove. After passing through the positioning hole, the positioning rod abuts against one end of the rotating plate located inside the mounting table.

[0018] By adopting the above technical solution, the second rodless electric cylinder drives the positioning rod to move into the receiving groove and pushes the rotating plate to rotate, so that the rotating plate disengages from the mounting seat, facilitating the removal of the mounting seat from the mounting table.

[0019] Optionally, a connecting plate is rotatably arranged on the lower surface of the mounting seat. The camera or the lighting lamp is arranged on the lower surface of the connecting plate. An adjusting component is arranged on the mounting seat. The adjusting component is used to adjust the angle between the connecting plate and the mounting seat.

[0020] By adopting the above technical solution, the camera or the lighting lamp is installed on the lower surface of the connecting plate. The adjusting component adjusts the angle between the connecting plate and the mounting seat, thereby facilitating the adjustment of the monitoring angle of the camera and the lighting range of the lighting lamp.

[0021] Optionally, the adjusting component includes a driving member, a rotating shaft, and a threaded sleeve. A transmission cavity is formed in the mounting seat. The rotating shaft is rotatably arranged on the mounting seat. One end of the rotating shaft extends horizontally towards the guide rail, and the other end extends into the transmission cavity. The threaded sleeve is rotatably connected to the mounting seat. One end of the threaded sleeve is located in the transmission cavity, and the other end extends towards the connecting plate. A screw rod is threadedly inserted into the threaded sleeve. A second sliding groove is formed in the connecting plate, and a slider is slidably arranged in the second sliding groove. The end of the screw rod is hinged to the slider. A driving gear is arranged at one end of the rotating shaft located in the transmission cavity, and a driven gear is arranged at one end of the threaded sleeve located in the transmission cavity. The driven gear meshes with the driving gear. The driving member is arranged on the moving plate and is used to drive the rotating shaft to rotate when the moving plate abuts against the mounting seat.

[0022] By adopting the above technical solution, the driving member drives the rotating shaft to rotate. The driving gear on the rotating shaft drives the meshing driven gear to rotate, thereby driving the threaded sleeve to rotate. The end of the screw rod is connected to the slider, and the screw rod cannot rotate. Therefore, the length of the screw rod located in the threaded sleeve changes with the rotation of the threaded sleeve, so as to adjust the distance between one end of the connecting plate and the mounting seat, and further realize the adjustment of the angle between the connecting plate and the mounting seat.

[0023] Optionally, the driving member includes a driving motor, a first turntable, and a second turntable. The driving motor is arranged on the side wall of the moving plate facing away from the support frame. A circular groove is formed in the side wall of the moving plate facing the support plate. The output shaft of the driving motor extends horizontally into the circular groove. The first turntable is located in the clamping groove and is connected to the output shaft of the driving motor. The second turntable is located on the side of the mounting seat facing the guide rail and is connected to the rotating shaft. A clamping groove is formed in the first turntable, and a clamping block adapted to the clamping groove is arranged on the second turntable.

[0024] By adopting the above technical solution, when the angle of the camera or the lighting lamp needs to be adjusted, the rail vehicle moves to face the corresponding mounting table, the moving plate is driven to move until it abuts against the mounting seat. The first turntable and the second turntable are clamped through the clamping block and the clamping groove. The driving motor drives the first turntable to rotate, and then drives the second turntable to rotate, achieving the effect of facilitating the rotation of the rotating shaft.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. A plurality of mounting platforms are installed on the support frame. When the rail vehicle moves to face one of the mounting platforms, the moving assembly is used to move the mounting seat to the mounting platform, and the fixing assembly is used to fix the mounting seat on the mounting platform; when removing the mounting seat, the dismounting assembly removes the mounting seat from the mounting platform, and the moving assembly moves the mounting seat to the rail vehicle; thus, it is convenient to install or remove a camera or a lighting lamp from the top of the tunnel, without the need for tools such as engineering ladders, so as not to affect the normal traffic of the highway.

[0027] 3. After the mounting seat is moved to the mounting platform, the rotating plate rotates under the action of the tension spring to abut against the side wall of the abutting groove, thereby clamping the mounting seat between the baffle and the rotating plate, achieving the effect of conveniently fixing the mounting seat on the mounting platform.

[0028] 6. The second rodless electric cylinder drives the positioning rod to move into the receiving groove and pushes the rotating plate to rotate, so that the rotating plate disengages from the mounting seat, facilitating the removal of the mounting seat from the mounting platform.

[0029] 9. The driving member drives the rotating shaft to rotate, and the driving gear on the rotating shaft drives the driven gear engaged therewith to rotate, thereby driving the threaded sleeve to rotate.

When the electromagnet 721 is started, the electromagnet 721 generates a suction force on the mounting seat 6 .

[0044] When the mounting seat 6 on the rail car 4 is moved to the mounting platform 5, the first rodless electric cylinder 71 is started, and the slide of the first rodless electric cylinder 71 drives the movable plate 72 to move toward the mounting platform 5, thereby pushing the mounting seat 6 onto the mounting platform 5; when the mounting seat 6 on the mounting platform 5 is removed, the movable plate 72 is moved close to the mounting platform 5, and the electromagnet 721 is started. The electromagnet 721 adsorbs the mounting seat 6, and drives the movable plate 72 to drive the mounting seat 6 to move onto the rail car 4.

[0045] Reference Figure 2 and Figure 4 A baffle 52 is installed on the side of the mounting platform 5 away from the guide rail 2. When the mounting seat 6 moves onto the mounting platform 5, the side wall of the mounting seat 6 contacts the baffle 52. The fixing assembly 8 includes a rotating plate 81 and a tension spring 82. A receiving groove 53 is provided on the lower surface of the mounting platform 5 and between the two second slide rails 51.
