DETAILED DESCRIPTION
[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0026] like Figure 1 and Figure 2 As shown, an embodiment of the present application provides a municipal bridge guardrail structure, including a bridge deck 1, a railing 2 is arranged on one side of the bridge deck 1, a first protective component 3 is arranged on the bridge deck 1, the first protective component 3 includes a plurality of protective columns 31 arranged in an interval array, the protective columns 31 are slidingly connected to the bridge deck 1 along the Y-axis direction, a power component is arranged on the bridge deck 1, which can drive the protective columns 31 to rotate to absorb energy when the protective columns 31 move, a second protective component 4 is arranged between the first protective component 3 and the railing 2, and a pedestrian bridge 5 is arranged above the second protective component 4.
[0027] Specifically, railings 2, a first protection component 3 and a second protection component 4 are provided on both sides of the bridge.
[0028] During operation, when a car accidentally deviates to the sides of the bridge, the car hits the guard column 31, and the guard column 31 is forced to move toward the railing 2 along the Y-axis direction. At the same time, the guard column 31 rotates, and the rotational force is transmitted to the car, which has a certain force unloading and energy absorption effect on the impact force of the car, making it difficult for the car to exceed the range of the guardrail. When the car rushes out of the guardrail, the second protection component 4 cushions the car to further prevent the car from falling off the bridge.
[0029] The above structure is set up, by arranging the first protection component 3 and the second protection component 4 in the railing 2 of the bridge deck 1 for double protection, so that the car is not easy to fall off the bridge, the first protection component 3 is set to include a protection column 31, the protection column 31 is set to be slidably connected to the bridge deck 1, and a power component is set to drive the protection column 31 to rotate when the protection column 31 moves, so that when the car hits the protection column 31, the protection column 31 is forced to move, and at this time the power component drives the protection column 31 to rotate, and the front of the car is against the protection column 31. When the protection column 31 rotates, the impact of the car is absorbed, reducing the impact force, and the protection column 31 can move a certain distance, so that the contact time between the protection column 31 and the car is increased, and the action time of the protection column 31 on the car is increased, and the action effect is good. By arranging the second protection component 4, the car is further prevented from falling off the bridge, and by arranging the pedestrian bridge 5 above the second protection component 4, the car is not easy to collide with pedestrians, thereby ensuring the safety of pedestrians.
[0030] In this embodiment, Figure 2 , Figure 3 and Figure 4 As shown, a first slide groove 11 is provided on the bridge deck 1, a limiting groove is provided on the side wall of the first slide groove 11, the bottom of the protective column 31 is rotatably connected with a slider 312 adapted to the first slide groove 11, a limiting block adapted to the limiting groove is provided on the slider 312, the slider 312 is slidably connected to the first slide groove 11, and the limiting block is slidably connected to the limiting groove.
[0031] The above structure is set up by setting a first slide groove 11 on the bridge deck 1, rotating the connecting slider 312 on the protective column 31, slidingly connecting the slider 312 with the first slide groove 11, setting a limit groove on the first slide groove 11, and setting a limit block on the slider 312, so that the slider 312 remains slidingly connected with the first slide groove 11, so that the protective column 31 can slide along the first slide groove 11.
[0032] In this embodiment, Figure 2 , Figure 3 and Figure 4 As shown, the power assembly includes a rack 12 fixedly connected to the bridge deck 1 , and a gear 311 is fixedly connected to the protective column 31 , and the gear 311 is meshed with the rack 12 .
[0033] During operation, when the protection column 31 moves along the first slide groove 11, since the gear 311 on the protection column 31 is meshed with the rack 12 on the bridge deck 1, the protection column 31 rotates while moving, which is convenient for buffering the car.
[0034] In this embodiment, Figure 1As shown, a protection cover 13 for protecting the power assembly is bolted to the bridge deck 1 , and a clearance groove is provided on the protection cover 13 for the protection column 31 to slide along the first slide groove 11 .
[0035] The above structure is arranged such that a protective cover 13 is provided on the bridge deck 1 to protect the power assembly, namely the rack 12 and the gear 311, so that the gear 311 and the rack 12 are not easily damaged, and the protective cover 13 is connected to the bridge deck 1 by bolts, so that when the protective column 31, the gear 311 or the rack 12 is damaged, it is easier to repair and replace.
[0036] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, a spacer block 14 is provided on one side of the first slide groove 11 close to the second protection component 4 , and the spacer block 14 is connected to the slider 312 via a first spring 3121 .
[0037] The above structure is arranged so that the slider 312 is connected to the spacer 14 via the first spring 3121 , so that the protection column 31 is also subjected to elastic force when moving along the first slide groove 11 , thereby further improving the buffering effect of the protection column 31 on the car.
[0038] In this embodiment, Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the second protective component 4 includes a buffer pad 41, fixed blocks 15 are provided at both ends of the bridge deck 1, and connecting rods are provided on the fixed blocks 15. The two ends of the buffer pad 41 are respectively hinged to the two connecting rods, and a conical groove 411 is provided at the bottom of the buffer pad 41 on the side close to the first protective component 3. A push block 16 is slidably connected on the bridge deck 1 between the spacer block 14 and the buffer pad 41, and the side of the push block 16 close to the conical groove 411 is adapted to the conical groove 411, a driving rod 3122 is fixedly connected to the slider 312, and a connecting hole for the driving rod 3122 to pass through is provided on the spacer block 14, and the end of the driving rod 3122 away from the slider 312 is fixedly connected to the push block 16.
[0039] Specifically, the driving rod 3122 passes through the first spring 3121 .
[0040] During operation, when a car hits the protective column 31, the slider 312 moves toward the spacer block 14, so that the driving rod 3122 moves toward the buffer pad 41. During the movement of the driving rod 3122, the push block 16 moves toward the buffer pad 41. Since the buffer pad 41 is provided with a conical groove 411, when the push block 16 moves toward the conical groove 411, the push block 16 props up the buffer pad 41. When the car rushes through the protective column 31 and moves toward the railing 2, the buffer pad 41 can buffer the car and prevent the car from breaking through the railing 2. When not in use, the buffer pad 41 is attached to the bridge deck 1, thereby avoiding the influence of the buffer pad 41 on the aesthetics and light transmittance of the bridge deck 1 when it is erected.
[0041] In this embodiment, Figure 5 As shown, the buffer pad 41 includes a first buffer block 412 and a second buffer block 413, the first buffer block 412 is hinged to the second buffer block 413, the two ends of the first buffer block 412 are respectively hinged to the two connecting rods, the first buffer block 412 is fixedly connected to the side close to the bridge deck 1 with a second spring 4121, the end of the second spring 4121 away from the first buffer block 412 is fixedly connected to the second buffer block 413, and the fixed block 15 is provided with a limiting component for limiting the first buffer block 412 and the second buffer block 413.
[0042] Specifically, the first buffer pad 41 and the second buffer pad 41 can both be made of EVA material.
[0043] The above structure is arranged by setting the buffer pad 41 to include a first buffer block 412 and a second buffer block 413, and arranging a spring between the first buffer block 412 and the second buffer block 413. When the buffer pad 41 is lifted up, the second buffer block 413 is close to the vehicle position, so the vehicle hits the second buffer block 413. Through the triple buffering of the second buffer block 413, the spring and the first buffer block 412, the risk of the car breaking the railing 2 and falling off the bridge is reduced.
[0044] In this embodiment, Figure 2 , Figure 5 , Figure 6 and Figure 7As shown, the limiting assembly includes a limiting ball 151, and the buffer pad 41 is provided with a slot 4122 adapted to the limiting ball. A limiting ball slot is provided on the side of the fixed block 15 close to the buffer pad 41, and the limiting ball slot extends along the X-axis direction. The limiting ball 151 is slidably connected to the limiting ball slot, and a power ball slot is provided on the fixed block 15 located between the limiting ball slot and the push block 16. A power ball 152 is slidably connected in the power ball slot, and one end of the limiting ball slot away from the buffer pad 41 is connected to the other end of the power ball slot away from the buffer pad 41 through a connecting slot. The limiting ball 151 is connected to the power ball 152 through a connecting block 153, and the connecting block 153 is slidably connected to the connecting slot, and the connecting block 153 is connected to the end of the connecting slot away from the buffer pad 41 through a third spring 154. A guide slope 161 is provided on the side of the push block 16 close to the power ball 152.
[0045] It should be noted that under the normal extension of the third spring 154 , half of the power ball and the limiting ball extend out of the fixed block 15 .
[0046] During operation, when the protective column 31 is moved by impact, the push block 16 is moved toward the direction close to the power ball 152. When the push block 16 and the power ball 152 collide with each other, the guide slope 161 presses the part of the power ball 152 extending out of the fixed block 15 into the power ball groove along the X-axis direction. Since the limiting ball 151 and the power ball 152 are connected by the connecting block 153, the limiting ball 151 is also pressed into the limiting ball groove, so that the buffer pad 41 is no longer limited by the limiting ball 151. Under the action of the second spring 4121, the first buffer block 412 bounces upward slightly, and then the push block 16 continues to move forward, propping up a part of the entire buffer pad 41, so that the buffer pad 41 can block the car.
[0047] In this embodiment, the protection column 31 includes a steel column, and a rubber sleeve is provided on the outer circumference of the steel column.
[0048] The above structure is set up, by setting the protection column 31 as a steel column and arranging a rubber sleeve on the outer periphery of the steel column, so that the protection column 31 has a certain strength and a certain buffering effect.
[0049] In this embodiment, Figure 1 As shown, a speed reduction block 17 is provided on the bridge deck 1 between the two protection covers 13 .
[0050] Specifically, the deceleration block 17 may be a rubber block, on which rubber strips are arranged in an array at intervals.
[0051] When the automobile rushes through the protective column 31, the deceleration block 17 can also play a buffering role.
[0052] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
