Abstract
Description
Technical Field
[0001] This application relates to the field of traffic congestion management technology, and in particular to a traffic congestion management device for highway ramp tunnels. Background Technology
[0002] When a car accident occurs on a highway ramp tunnel, the vehicle needs to wait for rescue at the scene, which will cause severe traffic congestion on the ramp tunnel. Traffic congestion mitigation devices can alleviate the congestion problem on the ramp tunnel caused by sudden accidents, high traffic volume or road failures.
[0003] Chinese patent CN204662197U, published in the relevant technology section, proposes a traffic management vehicle for alleviating highway traffic congestion. The vehicle includes a tractor unit, characterized in that a bridge body is connected to the rear of the tractor unit. The bridge body is a flat plate structure with four driving wheels at its bottom corners. It has two internal cavities, each containing a front and rear axle plate, both of which are retractable. This vehicle can form an emergency bridge at the accident site, allowing vehicles behind the accident to pass through in an orderly manner while traffic police are handling the accident, thus resolving highway congestion caused by the accident and saving significant time for other vehicles. It has strong feasibility and high economic benefits.
[0004] Regarding the aforementioned technologies, the lack of support devices for traffic diversion vehicles used to alleviate highway traffic congestion when parked at accident scenes results in poor stability of the parked vehicles. When vehicles travel over the front and rear axle plates, the diversion vehicles may shift and sway, making it difficult to guarantee the safety of vehicle operation. Utility Model Content
[0005] In order to overcome the technical problems described in the prior art, this application provides a traffic congestion relief device for highway ramp tunnels.
[0006] The technical solution for a traffic congestion mitigation device for highway ramp tunnels provided in this application is as follows:
[0007] A traffic congestion mitigation device for highway ramp tunnels, comprising:
[0008] The bridge structure is erected above the accident vehicle and is used to guide traffic. The bridge structure includes a horizontal plate and inclined ramps at both ends of the horizontal plate. One end of the ramps is connected to the end of the horizontal plate, and the other end is placed inclined on the ground.
[0009] A moving mechanism, installed at the bottom of a horizontal plate and used to move the bridge body, includes a bracket for supporting the horizontal plate and rollers installed at the bottom of the bracket; and
[0010] A support mechanism is provided on one side of the bracket and is used to lift the moving mechanism and the bridge body. The support mechanism includes a horizontal column connected to the bracket and a lifting assembly fixed on the horizontal column. By activating the lifting assembly, one end of the lifting assembly is pressed against the ground, and the other end lifts the moving mechanism and the bridge body through the horizontal column.
[0011] Furthermore, the lifting assembly includes a support base fixedly connected to the cross column, a movable seat that is slidably mounted on the support base, and a drive component that drives the movable seat to move up and down. The support base has a groove for slidingly connecting the movable seat, and the drive component is disposed between the support base and the movable seat.
[0012] Furthermore, the horizontal plate includes a housing and a sliding plate that is slidably inserted into the housing at one end. The housing and the sliding plate are arranged parallel to each other. The end of the housing away from the sliding plate is closed. One ramp is fixedly connected to the closed end of the housing, and the other ramp is fixedly connected to the end of the sliding plate away from the housing.
[0013] Furthermore, the housing is provided with a slide rail channel, and the slide plate is provided with a slider that is adapted to slide within the slide rail channel.
[0014] Furthermore, a sliding channel is provided through the bottom wall of the housing, the length direction of the sliding channel is consistent with the sliding direction of the slide plate, a connecting seat is fixed at the bottom of the slide plate, the connecting seat slides through the sliding channel, and a power component is also provided at the bottom of the housing to drive the connecting seat to slide back and forth in the sliding channel.
[0015] Furthermore, the ramp includes a storage shell fixedly connected to the horizontal plate and an inner plate telescopically slidably installed inside the storage shell, with a locking element between the storage shell and the inner plate for locking the two together.
[0016] Furthermore, the end face of the inner plate away from the storage shell is parallel to the horizontal plate.
[0017] Furthermore, the locking component is configured as a locking bolt, and the side wall of the housing has a through-hole for the locking bolt to pass through, and the inner plate has multiple threaded holes for the locking bolt to be threadedly connected.
[0018] Furthermore, the locking component is configured as a locking bolt, with a threaded hole through the side wall of the housing for the locking bolt to pass through, and an insertion hole for the locking bolt to be inserted into the inner plate.
[0019] Furthermore, the horizontal plate is provided with a power supply system for supplying power to the drive components and power assembly.
[0020] In summary, this application includes the following beneficial technical effects:
[0021] By setting up a support structure and using crossbeams and lifting components in combination, the bridge body is supported and fixed after parking, so that the bridge body will not shift or sway when vehicles drive on it. This avoids the problem in existing technologies where traffic diversion vehicles used to alleviate highway congestion lack support devices when parked at accident sites, resulting in poor stability of parked traffic diversion vehicles. The support mechanism ensures that the bridge body will not shift or sway when vehicles drive on the two ramps, thus guaranteeing the safety of vehicles driving on the bridge.

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.
[0030] This application discloses a traffic congestion mitigation device for highway ramp tunnels. (Refer to...) Figure 1 and Figure 2 A traffic congestion mitigation device for highway ramp tunnels includes a bridge body erected above accident vehicles for traffic diversion, two sets of moving mechanisms 4 for moving the bridge body, and two sets of supporting mechanisms 5 for supporting the bridge body. The bridge body includes a horizontal plate 31 and inclined ramp plates 32 at both ends of the horizontal plate 31. One end of the ramp plate 32 is connected to the end of the horizontal plate 31, and the other end is placed inclined on the ground. The two sets of moving mechanisms 4 are located at both ends of the bottom of the horizontal plate 31. The moving mechanism 4 includes a bracket 41 for supporting the horizontal plate 31 and two rollers 42 installed at the bottom of the bracket 41. A traction frame 2 is horizontally installed on the bracket 41. The two sets of supporting mechanisms 5 correspond one-to-one with the two brackets 41. The supporting mechanism 5 includes a horizontal column 51 fixedly connected to the bracket 41 and a lifting assembly 52 fixed on the horizontal column 51. When traffic management is required, the towing frame 2 pulls the support 41, which in turn moves the bridge body to the accident scene under the drive of the rollers 42. The bridge body is then positioned above the accident vehicles. The lifting assembly 52 is then activated, with one end pressed against the ground and the other end lifted by the crossbar 51, ensuring the rollers 42 do not contact the ground. At this point, the bridge body is stably positioned above the accident vehicles. Vehicles can then smoothly and stably leave the accident scene via the ramp 32 and the horizontal plate 31, alleviating traffic congestion to some extent.
[0031] To achieve stable erection and support of the bridge structure, refer to Figure 1 , Figure 2 and Figure 3The lifting assembly 52 includes a support base 521 fixedly connected to the cross column 51, a movable seat 522 slidably mounted on the support base 521, and a drive component for driving the movable seat 522 to move up and down. The support base 521 includes an inverted U-shaped seat body and a base plate fixed to the bottom of the seat body. The cavity between the two side walls of the seat body forms a groove 6 for slidingly connecting the movable seat 522. The movable seat 522 is assembled from two U-shaped movable plates. The open ends of the two movable plates interlock to form a U-shaped movable seat 522. The two end walls of the movable seat 522 slide and fit against the two side walls of the groove 6 on the support base 521, so that the movable seat 522 can move up and down smoothly on the support base 521. In this embodiment, the driving component includes a first lead screw 523 and a first motor 524. One end of the first lead screw 523 passes through the top wall of the movable seat 522 and the top wall of the support seat 521 and is rotatably connected to the bottom wall of the movable plate. The other end is fixedly connected to the output shaft of the first motor 524. The first lead screw 523 is rotatably connected to both ends of the movable seat 522. The first lead screw 523 is threadedly connected to the top wall of the support seat 521. The first motor 524 is fixedly installed on the top of the movable plate. The first motor 524 drives the first lead screw 523 to rotate on the movable seat 522, causing the support seat 521 to move downward under the threaded drive of the first lead screw 523 until the bottom plate of the support seat 521 is pressed against the ground. As the first motor 524 continues to drive the first lead screw 523 to rotate, the driving component and the movable seat 522 move upward on the support seat 521, thereby lifting the bridge body upward with the help of the cross column 51 until the roller 42 leaves the ground, thus achieving stable erection and support of the bridge body. In other embodiments, the driving component is a cylinder, hydraulic cylinder, electric push rod, etc., disposed in the slide groove 6.
[0032] Because the accident site is not fixed, the length of the horizontal slab 31 of the bridge is adjustable to allow the bridge to adapt to different accident sites. (Refer to...) Figure 1 and Figure 4The horizontal plate 31 includes a housing 311 and a sliding plate 312. One end of the housing 311 is closed, and the other end is open. One end of the sliding plate 312 is slidably inserted into the housing 311 through the open end of the housing 311. One ramp plate 32 is fixedly connected to the closed end of the housing 311, and another ramp plate 32 is fixedly connected to the end of the sliding plate 312 away from the housing 311. The housing 311 and the sliding plate 312 are arranged parallel to each other. A slide rail channel 7 is provided with an outward protrusion at the bottom of the housing 311. The length direction of the slide rail channel 7 is consistent with the sliding direction of the sliding plate 312. A slider 8 is provided with a protrusion at the bottom of the sliding plate 312 that is adapted to slide within the slide rail channel 7. The slider 8 is slidably installed within the slide rail channel 7, so that the sliding plate 312 can slide smoothly within the housing 311 under the constraint of the slider 8 and the slide rail channel 7. To ensure rapid adjustment of the horizontal plate 31 to the appropriate length, a sliding channel 11 is provided through the bottom wall of the housing 311. The length direction of the sliding channel 11 is consistent with the sliding direction of the slide plate 312. A connecting seat 10 is fixed to the bottom of the slide plate 312, and the connecting seat 10 slides through the sliding channel 11. A power assembly 9 is also provided at the bottom of the housing 311 to drive the connecting seat 10 to slide back and forth within the sliding channel 11. In this embodiment, the power assembly 9 includes a second lead screw 91 rotatably mounted at the bottom of the housing 311 and a second motor 92 fixed at the bottom of the housing 311 to drive the second lead screw 91 to rotate. A threaded hole 13 is provided through the connecting seat 10, and the connecting seat 10 is threadedly connected to the second lead screw 91 through the threaded hole 13. When the second motor 92 drives the second lead screw 91 to rotate, the second lead screw 91 drives the connecting seat 10 to move the slide plate 312 within the housing 311, thereby achieving the purpose of adjusting the length of the horizontal plate 31. In other embodiments, the power assembly 9 can be an electric actuator, a linear motor, a cylinder, etc. A power supply system 1 for supplying power to the drive components and the power assembly 9 is also provided at the bottom of the horizontal plate 31.
[0033] Considering that the lifting mechanism raises the bridge body upwards via the horizontal column 51, to prevent the ramp slab 32 from leaving the ground due to excessive lifting, therefore, referring to... Figure 1 and Figure 5The ramp plate 32 includes a housing 321 fixedly connected to a horizontal plate 31 and an inner plate 322 telescopically slidably installed within the housing 321. The end face of the inner plate 322 away from the housing 321 is parallel to the horizontal plate 31. A locking member 12 for locking the housing 321 and the inner plate 322 is provided between them. In this embodiment, the locking member 12 is a locking bolt. A threaded hole 13 for the locking bolt to pass through is provided on the side wall of the housing 321. A plurality of insertion holes 14 for the locking bolt to be inserted are provided along the length of the side wall of the inner plate 322. When the dredging device is being transported, the inner plate 322 can be slidably stored in the housing 321, and the locking bolt can be threaded through the threaded hole 13 and inserted into the insertion hole 14, making it difficult for the inner plate 322 to slide out of the housing 321. After the diversion device is transported to the accident site and its height is adjusted, the locking bolts can be removed, and the inner plate 322 can be pulled out from the housing 321 until the bottom of the inner plate 322 is pressed against the ground. Finally, the locking bolts are threaded through the threaded hole 13 and pressed against the side wall of the inner plate 322 or inserted into the insertion hole 14 on the side wall of the inner plate 322. This ensures that the bottom of the ramp 32 is always pressed against the ground during use, thus facilitating the smooth and stable departure of vehicles from the accident site via the ramp 32 and the horizontal plate 31.
[0034] The implementation principle of a traffic congestion mitigation device for highway ramp tunnels according to an embodiment of this application is as follows: First, the traction frame 2 pulls the support 41, which in turn moves the bridge body to the scene of the traffic accident under the drive of the rollers 42. Then, the power component 9 is activated, which drives the connecting seat 10 to slide the sliding plate 312 within the housing 311, adjusting the length of the horizontal plate 31 so that the bridge body can be smoothly erected above the accident vehicle. Then, the lifting component 52 is activated, so that one end of the lifting component 52 is pressed against the ground, and the other end is lifted by the horizontal column 51 to the moving mechanism 4 and the bridge body, ensuring that the rollers 42 do not contact the ground. At this time, the bridge body is stably erected above the accident vehicle. Next, the locking bolts are removed, and the inner plate 322 is pulled out from the housing 321 until the bottom end of the inner plate 322 is pressed against the ground. Finally, the locking bolt is threaded through the threaded hole 13 and pressed against the side wall of the inner plate 322 or inserted into the insertion hole 14 on the side wall of the inner plate 322. This ensures that the bottom of the ramp 32 is always pressed against the ground during use, which facilitates the smooth and stable departure of vehicles from the accident scene through the ramp 32 and the horizontal plate 31, thus alleviating traffic congestion to a certain extent.
[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
