Description

Technical Field

[0001] The utility model relates to the technical field of traffic engineering safety, in particular to a protection structure for traffic engineering. Background Art

[0002] With the development of society, the improvement of economic level, and the increasing number of vehicles, people pay more and more attention to the safety of vehicle driving on the road.

[0003] Some existing highways are provided with buffer roads for decelerating and braking out-of-control vehicles with brake failure, and such buffer roads are called emergency escape roads.

[0004] An emergency escape road usually has a sand pool at the end of the road. After an out-of-control vehicle drives into the sand pool, the sand in the sand pool will impede the driving of the vehicle and reduce the friction between the tires and the ground, thereby decelerating the vehicle until it is in a safe stationary state.

[0005] Although the above technology can effectively control out-of-control vehicles, the huge kinetic energy of out-of-control vehicles will cause some sand in the sand pool to be collided and scattered. After the vehicle is removed, it needs to be gradually cleaned manually to restore the sand pool to the state before buffering the out-of-control vehicle, and the restoration time is long and labor-consuming. Summary of the Utility Model

[0006] Aiming at the deficiencies of the existing technology, one of the purposes of the utility model is to provide a protection structure for traffic engineering, which has the effect of quickly restoring the buffer pool.

[0007] The above utility model purpose of the utility model is realized through the following technical solutions: A protection structure for traffic engineering includes a guiding road for guiding out-of-control vehicles; a buffer pool located in the guiding road, filled with buffer particles, and a reference plane is formed at the top of the buffer particles in the buffer pool; a flattening device having a first flattening roller and a second flattening roller, the bottom of the circumferential side walls of the first flattening roller and the second flattening roller are both parallel to the reference plane; a moving device that drives the flattening device to reciprocate along the length direction of the guiding road.

[0008] In a preferred example of the utility model, it can be further configured that: both the first flattening roller and the second flattening roller include a roller body and a scraping portion connected to the roller body, several scraping portions are arranged at intervals, and an overflow portion is arranged on one side of the scraping portion, the overflow portion is formed by the bottom of the circumferential side wall of the roller body and the reference plane, and the scraping portion of the first flattening roller corresponds to the overflow portion of the second flattening roller.

[0009] In a preferred example of the utility model, it can be further configured that: the bottoms of the scraping portions of the first flattening roller and the second flattening roller are both flush with the reference plane.

[0010] In a preferred example, the present utility model can be further configured as follows: the end of the leveling part of the first leveling roller is located within the range of the leveling part of the second leveling roller.

[0011] In a preferred example, the present utility model can be further configured as follows: there is one leveling part of the first leveling roller and it is located in the middle of the axial direction of the first leveling roller, and there are two leveling parts of the second leveling roller and they are respectively located at both ends of the axial direction of the second leveling roller.

[0012] In a preferred example, the present utility model can be further configured as follows: the bottom of the circumferential side wall of the leveling part of the first leveling roller and the leveling part of the second leveling roller are arranged at different heights, and the bottom of the leveling part of the first leveling roller is higher than the bottom of the leveling part of the second leveling roller.

[0013] In a preferred example, the present utility model can be further configured as follows: a reinforcing rod is arranged between the middle parts of the first leveling roller and the second leveling roller.

[0014] In a preferred example, the present utility model can be further configured as follows: the bottom wall of the buffer pool is inclined, and the lowest position of the bottom wall of the buffer pool is located in the middle of the buffer pool.

[0015] In summary, the present utility model includes at least one of the following beneficial technical effects:

[0016] 1. The flattening device reciprocates along the length direction of the guiding road through the moving device. During the moving process, the first leveling roller and the second leveling roller will carry the buffer particles that are washed away and higher than the reference surface, and re-backfill the buffer particles higher than the reference surface to the buffer pool area that has been washed away, thereby realizing the rapid restoration of the buffer pool.

[0017] 2. During the moving process of the first leveling roller and the second leveling roller, the leveling part will push the buffer particles that are washed away and higher than the reference surface, and the overflow part located on one side of the leveling part will reduce the operating area of the first leveling roller or the second leveling roller, thereby reducing the load borne by the first leveling roller and the second leveling roller during the moving process, that is, reducing the amount of force deformation of the first leveling roller and the second leveling roller, and further reducing the requirement for the structural stiffness of the long rod shape.

[0018] 3. The reinforcing rod can improve the connection performance between the first leveling roller and the second leveling roller, thereby supporting each other and improving the anti-deformation performance of the first leveling roller and the second leveling roller.

[0019] 4. The bottom of the buffer pool with an inclined setting is used to gradually buffer the vehicle when the out-of-control vehicle enters, extend the braking time, and reduce the impact of inertia on the vehicle occupants. Description of the Drawings

Detailed implementation manners

[0028] The following further elaborates on the present utility model in conjunction with the attached Figures 1-7 drawings.

[0029] Embodiment 1:

[0030] As Figure 1 , 2 shown, a protection structure for traffic engineering disclosed by the present utility model is connected to one side of a highway. The protection structure for traffic engineering includes a guiding road 1, a buffer pool 2 located at one end of the guiding road 1 away from the highway, a flattening device 3 located on the buffer pool 2, and a moving device 4 for driving the flattening device 3 to move.

[0031] The guiding road 1 is connected to the driving road and is used to divert out-of-control vehicles. The driving road can be a long downhill section or a highway.

[0032] The buffer pool 2 is located inside the guiding road 1. The buffer pool 2 is filled with buffer particles, and the top of the buffer particles in the buffer pool 2 forms a reference plane. The buffer particles can be grit, preferably coarse and medium sand.

[0033] The flattening device 3 has a first flattening roller 5 and a second flattening roller 6 which are spaced apart from each other and arranged in parallel. The bottoms of the circumferential side walls of the first flattening roller 5 and the second flattening roller 6 are both parallel to the reference plane.

[0034] The moving device 4 drives the flattening device 3 to reciprocate along the length direction of the guiding road 1.

[0035] The moving device 4 drives the first flattening roller 5 and the second flattening roller 6 of the flattening device 3 to reciprocate on the buffer pool 2. During the movement process, the buffer particles higher than the reference plane are pushed in the middle, and the buffer particles higher than the reference plane are re-filled into the area of the buffer pool 2 where it is washed away, thereby realizing the rapid restoration of the buffer pool 2. Compared with manually restoring the buffer pool 2, it has the effects of saving labor and enabling the buffer pool 2 to be quickly put back into use after being used.

[0036] The overall projection of the buffer pool 2 on the horizontal plane is rectangular. The length direction of the buffer pool 2 is arranged along the length direction of the guiding road 1, and the width direction is arranged along the width direction of the guiding road 1. The bottom wall of the buffer pool 2 is inclined towards the middle of its length direction. After filling the buffer particles, a large filling depth is formed in the middle of the buffer pool 2, and the depth at both ends becomes smaller as it gradually approaches the ends.

[0037] The flattening device 3 has an initial position, which is located at one end of the buffer pool 2 away from the guiding road 1 to reduce the probability of an out-of-control vehicle hitting the flattening device 3.

[0038] Refer to Figure 3 、 4 , both the first flattening roller 5 and the second flattening roller 6 include a roller body 8 and a scraping portion 9. The scraping portion 9 protrudes from the bottom of the circumferential side wall of the roller body 8, and the length dimension of the scraping portion 9 is smaller than the length dimension of the roller body 8. An overflow portion 10 is formed by a gap between the end of the scraping portion 9 and the reference plane.

[0039] Refer to Figure 2 、 5 , the roller body 8 is installed on the moving device 4.

[0040] The bottom ends of the scraping portions 9 of the first flattening roller 5 and the second flattening roller 6 are flush with the reference plane. The scraping portion 9 of the first flattening roller 5 corresponds to the overflow portion 10 of the second flattening roller 6, and the scraping portion 9 of the second flattening roller 6 corresponds to the overflow portion 10 of the first flattening roller 5. Among them, the dimension of the scraping portion 9 of the first flattening roller 5 along the length direction of the roller body 8 where it is located is X, and the dimension of the overflow portion 10 of the second flattening roller 6 along the length direction of the roller body 8 where it is located is Y. X is greater than Y, that is, the end of the scraping portion 9 of the first flattening roller 5 is located within the range of the scraping portion 9 of the second flattening roller 6.

[0041] Specifically, a scraping portion 9 is provided in the middle of the length direction of the first flattening roller 5, and the two ends of the length direction of the first flattening roller 5 are overflow portions 10. The middle of the length direction of the second flattening roller 6 is the overflow portion 10, and the two ends of the overflow portion 10 on the second flattening roller 6 along the length direction of the second flattening roller 6 are scraping portions 9.

[0042] Compared with the method of using a single rod to flatten and restore the buffer pool 2 in all directions of its width, the first flattening roller 5 and the second flattening roller 6 flatten and restore the buffer pool 2 in its width direction. Due to the setting of the overflow portion 10, the buffer particles that are not restored by the overflow portion 10 of the first flattening roller 5 will be restored by the scraping portion 9 of the second flattening roller 6, that is, the first flattening roller 5 and the second flattening roller 6 have different restoration areas, which distributes the stress during repair and avoids the situation where the resistance of the buffer particles is too large when using a single rod for repair, thereby ensuring the repair effect and reducing the requirements of the first flattening roller 5 and the second flattening roller 6 on the structural stiffness of the long rod shape, thereby increasing the range of material selection.

[0043] A reinforcing rod 7 is connected to each other at the middle of the first push roller 5 and the second push roller 6 in the length direction.

[0044] Reference Figure 5 , 6 There are two groups of moving devices 4, which are respectively arranged on both sides of the buffer pool 2 in the width direction. The moving devices 4 include a guide rail 11, a base 12, a driving motor 13 and a traveling gear 14.

[0045] The guide rail 11 is installed on one side of the buffer pool 2 and is arranged along the length direction of the buffer pool 2 . A meshing tooth portion 15 is arranged on the side of the guide rail 11 away from the buffer pool 2 . The meshing tooth portion 15 is arranged along the length direction of the guide rail 11 .

[0046] The base 12 is embedded in the guide rail 11 , and the base 12 is slidably connected to the guide rail 11 .

[0047] The driving motor 13 is mounted on the base 12 , and the output shaft of the driving motor 13 is fixedly connected to a traveling gear 14 . The traveling gear 14 is located on a side of the guide rail 11 away from the buffer tank 2 and meshes with the meshing tooth portion 15 .

[0048] The driving motor 13 runs, and the traveling gear 14 and the meshing tooth portion 15 cooperate with each other, thereby driving the base 12 to slide on the guide rail 11, and then driving the flattening device 3 located on the base 12. The traveling gear 14 and the meshing tooth portion 15 set away from the buffer pool 2 can reduce the buffer particles in the buffer pool 2 from entering the meshing position, thereby ensuring the service life of the traveling gear 14 and the meshing tooth portion 15.

[0049] Embodiment 2:

[0050] The difference between the second embodiment and the first embodiment is that Figure 7As shown, the bottom of the leveling part 9 of the first leveling roller 5 and the bottom of the peripheral side wall of the leveling part 9 of the second leveling roller 6 are set at different heights, and the bottom of the leveling part 9 of the first leveling roller 5 is higher than the bottom of the leveling part 9 of the second leveling roller 6.

[0051] The dimension of the leveling part 9 of the first leveling roller 5 along the length direction of the roller body 8 is X, and the dimension of the overflow part 10 of the second leveling roller 6 along the length direction of the roller body 8 is Y. X is equal to Y, that is, the end of the leveling part 9 of the first leveling roller 5 is located outside the range of the overflow part 10 of the second leveling roller 6 along the length of the buffer pool 2.

[0052] That is, after the buffer pool 2 is restored, the buffer particles will form a reference surface that is high in the middle and low on both sides.

[0053] The embodiments of the specific implementation manners are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention shall be covered within the protection scope of the present invention.
