Therefore, the present invention is not limited to the limitations of the specific embodiments disclosed in the following specification.

[0043] Embodiment 1, as Figures 1-9 shown, the present invention provides a sound-light flag-waving road gate machine for improving safe highway maintenance operations, including a road gate machine body 1 and a connecting mechanism 3. A railing 8 is installed on the upper surface of the road gate machine body 1. A strobe light 5 is installed on one side of the road gate machine body 1. A high-power horn 9 is installed on one inner wall of the road gate machine body 1. A swing machine 6 is installed on the other inner wall of the road gate machine body 1. The output end of the swing machine 6 is fixedly connected to a marking flag 7 by means of the connecting mechanism 3. A protection mechanism 2 is provided on one side of the road gate machine body 1. A connecting mechanism 3 is provided on the side of the swing machine 6 close to the marking flag 7. A protection mechanism 4 is provided on the side of the road gate machine body 1 close to the high-power horn.

[0044] The specific settings and functions of its protection mechanism 2, connecting mechanism 3 and protection mechanism 4 will be specifically described below.

[0045] As Figures 3-5As shown, the protection mechanism 2 includes a fixed plate 201, which is fixedly connected to one side of the gate machine body 1. A support block 202 is fixedly connected to the side of the fixed plate 201 away from the gate machine body 1. One side of the support block 202 is rotatably connected to an adjusting rod 203. One end of the arc surface of the adjusting rod 203 is fixedly connected to an assembly block 204, and the assembly block 204 is fixedly connected to the railing 8. One side of the railing 8 close to the gate machine body 1 is fixedly connected to an adjusting plate 205. An adjusting groove 206 is opened on one side of the adjusting plate 205. A slider 207 is slidably connected to the inner wall of the adjusting groove 206. One side of the slider 207 is fixedly connected to a limiting plate 208. One side of the limiting plate 208 is fixedly connected to a connecting block 209. A rotating rod 210 is threadedly penetrated through the inner wall of the connecting block 209, and the rotating rod 210 is threadedly connected to the inner wall of the adjusting plate 205. Two contact blocks 216 are fixedly connected to the side of the gate machine body 1 close to the limiting plate 208. The contact blocks 216 are elastic blocks, and both of the two contact blocks 216 are clamped with the inner wall of the limiting plate 208. Both ends of the side surface of the contact block 216 are fixedly connected to convex blocks 214. The high-safety road maintenance operation sound and light flag-waving gate machine body 1 is an intelligent transportation device that combines the light source warning of the flashing light 5, the warning of the identification flag 7 of the swing machine 6, the sound warning of the high-power horn 9, and the gate control warning of the gate machine body 1. It is mainly used for traffic control and safety guarantee in the road maintenance operation area. It is usually installed in the road maintenance operation area of roads or highways to ensure the safety of operators and control the traffic flow of passing vehicles. However, when in use, the operation of the gate machine body 1 will narrow the road surface. At this time, when a vehicle passes by the side of the gate machine body 1, the side edges of some vehicles will conflict with the railing 8. When the conflict is serious, it will cause the railing 8 to break, resulting in the entire gate machine body 1 being unable to continue to be used. At this time, through the protection mechanism 2, when the railing 8 conflicts with the vehicle, the railing 8 will perform angle adjustment. Thus, through the protection mechanism 2, the service life of the entire railing 8 can be improved, and the use effect of the gate machine body 1 can be extended. A plurality of anti-slip grooves 212 are opened at one end of the arc surface of the rotating rod 210, and the plurality of anti-slip grooves 212 are evenly distributed on the rotating rod 210. The anti-slip grooves 212 can improve the rotation speed of the rotating rod 210. The other end of the arc surface of the rotating rod 210 is fixedly connected to an auxiliary block 215. The auxiliary block 215 is funnel-shaped, and the auxiliary block 215 can improve the connection speed between the rotating rod 210 and the inner wall of the adjusting plate 205. A guiding rod 211 is fixedly connected to the bottom wall of the adjusting groove 206, and the guiding rod 211 is slidably connected to the inner wall of the slider 207. When the slider 207 slides into the adjusting groove 206, the guiding rod 211 can guide the sliding of the slider. A protective ring 213 is fixedly connected to one end of the arc surface of the rotating rod 210. The cross section of the protective ring 213 is circular ring-shaped, and the protective ring 213 can protect the contact position between the rotating rod 210 and the adjusting plate 205.

[0046] As Figure 6 andFigure 7 As shown in the figure, the connecting mechanism 3 includes an installation groove 31 which is opened on one side of the rocking machine 6. Two fixing blocks 32 are slidably connected to the inner wall of the installation groove 31. One side of each of the two fixing blocks 32 close to each other is fixedly connected to the identification flag 7. One end of the rocking machine 6 is fixedly connected to an adapter block 33. A plug rod 34 slidably penetrates through the inner wall of the adapter block 33. A spring 35 is sleeved on the arc surface end of the plug rod 34. Two ends of the spring 35 are respectively fixedly connected to the plug rod 34 and the adapter block 33. The plug rod 34 slidably penetrates through the inner wall of the rocking machine 6 and is slidably connected to the inner wall of the identification flag 7. When the identification flag 7 is damaged after long-term use, the identification flag 7 can be replaced through the connecting mechanism 3, thereby improving the use effect of the identification flag 7. Two protective pads 36 are fixedly connected to the bottom wall of the installation groove 31. The cross section of the protective pad 36 is rectangular. The protective pad 36 can prevent the fixing block 32 from contacting the installation groove 31 and being worn. A pull ring 37 is rotatably connected to the inner wall of the plug rod 34. The pull ring 37 can improve the speed of pulling the plug rod 34.

[0047] As Figure 8 and Figure 9 shown in the figure, the protection mechanism 4 includes a protection plate 43 which is slidably connected to one side of the gate machine body 1. Two mounting blocks 42 are fixedly connected to one side of the protection plate 43. A limiting block 41 slidably penetrates through the inner wall of the mounting block 42. One side of each of the two limiting blocks 41 is fixedly connected to the gate machine body 1. The two ends of the protection plate 43 are fixedly connected to the same connecting belt 44. The connecting belt 44 is an elastic belt. Two clamping blocks 46 are slidably connected to one side of the connecting belt 44. One side of each of the two clamping blocks 46 is fixedly connected to one side of the gate machine body 1. A plurality of through holes 45 are formed in the side surface of the protection plate 43. The plurality of through holes 45 are evenly distributed on the protection plate 43. A handle 49 is fixedly connected to the side of the protection plate 43 away from the gate machine body 1. A sealing ring 48 is fixedly connected to the side of the protection plate 43 close to the gate machine body 1. When using the gate machine body 1, the protection mechanism 4 can be fixed on one side of the high-pitched horn 9. Through the protection mechanism 4, the high-pitched horn 9 can be protected from being damaged by impact. An adjusting block 47 is fixedly connected to the surface of the connecting belt 44. When it is necessary to pull the connecting belt 44, the adjusting block 47 installed on the connecting belt 44 can be used to pull the connecting belt 44, thereby improving the speed of pulling the connecting belt 44.

[0048] ​The overall working principle is that when the vehicle collides with the pull rod, the railing 8 will transmit the force to the adjusting plate 205. The movement of the adjusting plate 205 will drive the adjusting rod 203 to rotate on the support block 202 through the assembly block 204. At this time, the adjusting plate 205 will rotate with it. The movement of the adjusting plate 205 will drive the limiting plate 208 to move together. The movement of the limiting plate 208 will squeeze the contact block 216, thereby driving the contact block 216 to deform. At this time, the limiting effect of the contact block 216 on the limiting plate 208 can be released, and the railing 8 can be adjusted in angle along with the adjusting rod 203, so as to avoid damage to the railing 8 due to collision. When it is necessary to reset the railing 8, rotate the rotating rod 210 out of the connecting block 209. At this time, the fixing effect on the limiting plate 208 and the slider 207 can be released. The slider 207 can drive the limiting plate 208 to slide upward in the adjusting groove 206. At this time, the railing 8 can be turned back to its original position. Align the angle of the limiting plate 208 with the contact block 216, and then slide the slider 207 in the adjusting groove 206 to drive the limiting plate 208 to slide until the limiting plate 208 comes into contact with the contact block 216 again. Then, rotate the rotating rod 210 in the connecting block 209 to fix the limiting plate 208 again. The anti-slip groove 212 can increase the rotation speed of the rotating rod 210, and the auxiliary block 215 can increase the connection speed between the rotating rod 210 and the inner wall of the adjusting plate 205. When the slider 207 slides into the adjusting groove 206, the guiding rod 211 can guide the sliding, and the protective ring 213 can protect the contact position between the rotating rod 210 and the adjusting plate 205.

[0049] Pull the insertion rod 34. The movement of the insertion rod 34 can drive the spring 35 to deform. The insertion rod 34 will be pulled out from the identification flag 7 and the inner wall of the rocking machine 6. At this time, the damaged identification flag 7 can be taken out from the rocking machine 6. Then, align the fixing block 32 installed on the new identification flag 7 with the installation groove 31, press the identification flag 7, and release the insertion rod 34. The reset of the spring 35 can drive the insertion rod 34 to fix the identification flag 7 through the rocking machine 6. The protective pad 36 can prevent the fixing block 32 from contacting the installation groove 31 and being worn, and the pull ring 37 can increase the speed of pulling the insertion rod 34.

[0050] Pull the connecting belt 44 to connect the deformed connecting belt 44 to the surface of the gate machine body 1. Connect the inner walls of the two fixing blocks 32 to the surfaces of the limiting blocks 41 respectively. Align the angle of the connecting belt 44 with the two clamping blocks 46, and then release the connecting belt 44. Then, the protection plate 43 can be fixed on one side of the gate machine body 1 through the connecting belt 44. The sealing ring 48 installed on the protection plate 43 improves the contact stability between the protection plate 43 and the gate machine body 1. When it is necessary to pull the connecting belt 44, the connecting belt 44 can be pulled through the adjusting block 47 installed on the connecting belt 44, thereby increasing the speed of pulling the connecting belt 44.

[0051] The above are only the preferred embodiments of the present invention, and do not limit the present invention in other forms. Any person skilled in the relevant art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields.
