[0047] Embodiment 1
[0048] As Figures 1-9 shown, a mechanical warning device for highway driving includes a warning sign box 1 and a trigger rope 2;
[0049] The warning sign box 1 is used to be fixedly arranged above the driving lane of the highway. For different highways, such as a tunnel 5, the warning sign box 1 can be directly arranged on the inner top of the tunnel 5. As Figure 1 and Figure 8 shown, a vertical sling 51 can be used to hang the warning sign box 1 on the top of the tunnel 5. The vertical sling 51 can have various options, such as using a vertical boom 511 or a vertical cable, etc. The vertical boom 511 can be a steel section member to make the hanging of the warning sign box 1 more stable. Of course, on the basis of setting the vertical boom 511, an anti-falling suspension rope 512 with a redundancy can also be set. The length of the anti-falling suspension rope 512 is greater than the vertical height of the vertical boom 511, so as to ensure safer use. Of course, the warning sign box 1 can be directly anchored on the top of the tunnel 5 by means of bolts, etc.
[0050] For a highway in an open condition, a gantry 3 can be set across the highway. That is, the warning device further includes a gantry 3. The gantry 3 is erected above the highway, and the warning sign box 1 is arranged on the top of the gantry 3. As Figure 7 and Figure 9As shown in the figure, the gantry 3 includes columns 31 on both sides and a crossbeam 32 in the middle. The box body 11 of the warning sign box 1 can be fixed to the crossbeam 32 through anchor bolts 1515. These methods can reduce the impact of the installation of the warning sign box 1 on the vertical clearance above the traffic lane 4.
[0051] The warning sign box 1 has a box body 11 and a switch 14. The box body 11 has a downward opening, and a warning structure is provided inside the box body 11. When the opening of the box body 11 is opened, the warning structure can fall out of the opening to the outside of the box body 11, so that the warning structure can give a warning. Vertical limiting devices such as a baffle 12 and a stop bar can be provided at the opening, which can make the warning structure located inside the box body 11 when no warning is needed. When the baffle 12 is used, it can be a push-pull structure or a flipping structure, etc.
[0052] The warning structure can be a warning sign 132 or a warning flag 131, etc. (visual) structures that can give a warning, such as Figure 1 、 Figure 2 and Figure 7 As shown in the figure, the warning structure is a warning sign 132. The warning sign 132 is connected inside the box body 11 through a hanging rope 1321 and can be hung through the hanging rope 1321 after falling. Among them, as Figure 1 shown in the figure, the warning sign 132 is folded inside the box body 11. As Figure 2 and Figure 7 shown in the figure, when the opening is opened, the warning sign 132 falls out of the box body 11 and unfolds, and is hung through the hanging rope 1321. Optionally, the warning sign 132 is a heavier structure, such as Figure 7 shown in the figure. Optionally, the warning sign 132 is a lighter structure. For example, if it is made of a foam structure, a counterweight 1322 is provided at the bottom of the hanging rope 1321 to ensure that the foam structure warning sign 132 can fall smoothly and ensure its stability in the warning operation state.
[0053] Such as Figure 8 and Figure 9 shown in the figure, the warning structure can be a warning flag 131. The top of the warning flag 131 is fixed inside the box body 11, which is convenient for storage inside the box body 11 and can be directly connected to the box body 11. The warning flag 131 can also be folded inside the box body 11. When the opening below the box body 11 is opened, the warning flag 131 falls out of the box body 11 and unfolds.
[0054] The trigger rope 2 is connected to the switch 14. The trigger rope 2 can pull the switch 14 to open the downward opening of the box body 11 so that the warning structure inside the box body 11 falls out of the opening and hangs. For reference, see Figure 3 and Figure 4, the switch 14 can be pulled. For example, a baffle 12 is hinged to one side below the box body 11, such as connected by a hinge 16. The hinge axis of the box body 11 and the baffle 12 is arranged horizontally along the road. Corresponding sliding grooves 142 are provided on the other side of the baffle 12 and the box body 11. The notch 143 of the sliding groove 142 is arranged facing away from the box body 11. The switch 14 includes a sliding rod 141, and the sliding rod 141 can slide in the sliding groove 142. The trigger rope 2 is connected to the outside of the sliding rod 141 corresponding to the notch 143 of the sliding groove 142. With this structural design, when the trigger rope 2 pulls the sliding rod 141 to move horizontally along the road, it will not interfere with the box body 11 and the baffle 12, and can ensure that the baffle 12 can be turned downwards to open. Of course, in addition to this design, for example, a bolt structure can be used. The bolt is connected to the trigger rope 2, and the trigger rope 2 is connected to the bolt to realize the function of the switch 14 to open the opening below the box body 11.
[0055] In some embodiments, in order to reduce the interference of the trigger rope 2 on the clearance above the driving lane 4, the trigger rope 2 needs to be steered so that the trigger rope 2 is located on the top surface and side surface of the driving lane 4. The warning device further includes a first steering pulley group. The axial direction of the first steering pulley group is longitudinally along the road. The first steering pulley group is arranged along the side surface and top surface of the gantry 3 or the tunnel 5. The trigger rope 2 is wound around the first steering pulley group, and a part of the trigger rope 2 is located between the first steering pulley group and the wall of the gantry 3 or the tunnel 5. The steering wheels of the first steering pulley group can steer the laying direction of the trigger rope 2, so that the trigger rope 2 can be laid along the cross section of the tunnel 5 or the gantry 3, which can reduce the interference on the clearance above the driving lane 4 and does not affect the smoothness when the trigger rope 2 is pulled. As Figure 1 , Figure 2 , Figures 7-9 shown. Among them, according to the setting of the trigger rope 2, the first steering pulley group may be only on one side, or may need to be set on both sides.
[0056] As Figure 7 and Figure 8 shown, in some embodiments, the warning device further includes a weight 7. The weight 7 is located on one side of the gantry 3 or one side of the tunnel 5. One end of the trigger rope 2 is connected to the weight 7, and the weight 7 can fall to pull the switch 14 to open the downward opening of the box body 11. For example, before warning, the warning structure is located in the box body 11, then the weight 7 is guaranteed at a certain height. When warning is needed, the weight 7 can fall a certain distance, so that the trigger rope 2 pulls the switch 14 to open the lower opening of the warning box. In order to prevent the weight 7 from falling into the driving lane 4 after falling, a limiting mechanism 71 of the weight 7 can also be set, such as a vertical limiting groove, to ensure that the weight 7 falls into the limiting groove.
[0057] As Figure 7 and Figure 8As shown, further, the first steering pulley set is arranged along the two side surfaces and the top surface of the gantry 3 or the tunnel 5. The middle of the trigger rope 2 is connected to the switch 14, and the other end of the trigger rope 2 is detachably connected to the inner bottom of the tunnel 5 on the other side after winding around the first steering pulley set on the other side (corresponding to the side of the road, arranged outside the driving lane to avoid interfering with driving). The trigger rope 2 is detachably connected to the side of the road at the bottom of the tunnel 5 on this side. After detachment, under the action of the self-weight of the weight 7, it can ensure that the trigger rope 2 pulls the switch 14.
[0058] Further, as Figure 5 , Figure 7 and Figure 8 shown, the warning device further includes a second steering pulley set and a first bracket 8. The first bracket 8 and the second steering pulley set are both arranged at the same-side bottom of the gantry 3 or the tunnel 5;
[0059] The first bracket 8 includes two vertical plates 81. The two vertical plates 81 are fixed at intervals along the longitudinal direction of the road on the side of the road. The two vertical plates 81 have corresponding pin holes. The axial direction of the pin holes is along the longitudinal direction of the road, and a horizontal pin is arranged in the pin holes, and the pin can be pulled out of the pin holes;
[0060] The axial direction of the second steering pulley set is the transverse direction of the road. After the trigger rope 2 bypasses the second steering pulley set, it is sleeved on the pin arranged below and is located between the two vertical plates 81. The second steering pulley set is used for steering to make the movement of the trigger rope 2 smooth. Figure 5 In, two second steering pulley sets are arranged. The second steering pulley set on the left is connected to the side wall of the tunnel 5 or the column 31 of the gantry 3, and the second steering pulley set on the right is arranged on the third bracket 221. The third bracket 221 is composed of vertical plates 81 and inclined plates, etc. The second steering pulley set on the right is arranged on the inclined plate. Through the two second steering pulley sets on the left and right, it can ensure that the trigger rope 2 is in a tensioned state and ensure the direction when pulling.
[0061] In the initial state, as Figure 5 shown, the trigger rope 2 is limited by the pin and the two vertical plates 81 on both sides. After the pin is pulled out of the pin hole, one end of the trigger rope 2 is released. Under the action of the gravity of the weight 7 at the other end, the trigger rope 2 can pull the switch 14.
[0062] In addition to using the method of the weight 7, in some embodiments, as Figure 1 and Figure 2As shown in the figure, an elastic structure 6 can be provided at one end of the trigger rope 2. The elastic structure 6 has a pre-tension. One end of the elastic structure 6 is fixed to one side of the gantry 3 or one side of the tunnel 5. The other end of the elastic structure 6 is connected to one end of the trigger rope 2. The middle of the trigger rope 2 is connected to the switch 14, and the other end of the trigger rope 2 is connected to the bottom of the other side of the gantry 3 or the bottom of the other side of the tunnel 5. The elastic structure 6 can be a spring, enabling the trigger rope 2 to be pulled. The elastic structure 6 can be in an initial state, so that when a pulling force is applied to the other end of the trigger rope 2, the trigger rope 2 can move and pull the switch 14 to open the opening of the box body 11.
[0063] This method can adopt Figure 6 the connection structure in the figure. The warning device may further include a horizontal support 91, a vertical support 92, a transmission roller 93 and a return spring 94;
[0064] The horizontal support 91 and the vertical support 92 are fixedly connected. The vertical support 92 is fixed on the side of the road. The transmission roller 93 is rotatably connected to the vertical support 92. The transmission roller 93 has a connecting ear, and the trigger rope 2 is connected to the connecting ear. The return spring 94 is connected to the connecting ear and the horizontal support 91. When the transmission roller 93 rotates, it can pull the trigger rope 2 to open the switch 14. After the transmission roller 93 is not stressed, the return spring 94 can reset the transmission roller 93. This setting method can also set a second steering pulley group, as shown in the left side of Figure 6 the figure.
[0065] In addition, as shown in Figure 5 and Figure 6 the figure, a pull rope 83 can be set in both of the above two methods. The pull rope 83 can be used to provide a pulling force or directly connected to the driving lane 4. When the driving lane 4 undergoes a large deformation, the pull rope 83 can be pulled, and then the trigger rope 2 can pull the switch 14.
[0066] The mechanical warning device for highway driving of this embodiment is adopted, by fixing the warning sign box 1 above the roadway, and by pulling the trigger rope 2, the trigger rope 2 pulls the switch 14 of the warning sign box 1, and then opens the downward opening of the box body 11 of the warning sign box 1, so that the warning structure in the box body 11 falls out of the opening and hangs, and gives a warning to ensure driving safety. Pulling the trigger rope 2 can be done manually, or the trigger rope 2 can be connected to the road, etc. When the road is damaged or displaced, the trigger rope 2 is pulled. This mechanical method enables the warning structure to give a warning, and even in extreme cases such as power outages and network disconnections, it can give a warning, thereby improving driving safety. The warning device adopts a mechanical auxiliary warning reminder, and the warning facilities include warning flags and warning signs. When a disaster occurs, the vehicle is reminded by the warning flag sign hanging above the roadway while driving to the disaster site. The warning device designed by this patent triggers the switch of the mechanical device by shifting the trigger rope to produce an emergency warning effect. It has less reliance on environmental factors, has no electricity and communication requirements, and has high stability, reliability and timeliness. When natural disasters cause the main beam to collapse, the warning device can be activated in time to remind drivers and passengers to slow down and stop, thereby achieving the purpose of reducing the loss of life and property caused by disasters.
[0067] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
