Description

Technical Field

[0001] The utility model relates to the technical field of bridge and tunnel protection, in particular to a bridge and tunnel transition section protection device based on waste tires. Background Art

[0002] Vehicle accidents are prone to occur in the transition section between bridges and tunnels. Currently, protective devices are generally made from waste tires to provide safety protection for the transition section between bridges and tunnels. This can not only reduce vehicle damage, but also recycle waste tires and reduce device costs.

[0003] After searching, the Chinese patent authorization number CN220908250U discloses a guardrail for recycling waste tires, comprising a plurality of guardrail posts evenly spaced along a highway, wherein adjacent guardrail posts are connected by an upper pull rod and a lower pull rod, and a support cage is provided at the middle of each guardrail post for vertical sliding in the direction of the guardrail, wherein the support cage comprises two limit rings and a plurality of guide rods, wherein the two ends of the plurality of guide rods are respectively vertically connected to the two limit rings, and the plurality of guide rods are evenly spaced along the circumference of the limit rings, and some of the guide rods located on the opposite side of the support cage slide through the guardrail post, and the support cage on the inner side of the guardrail post is provided with a waste tire, and the waste tire is connected to the limit ring facing the highway side; when the guardrail is hit by a vehicle, the waste tire is deformed and the support cage moves toward the outside of the guardrail to buffer and absorb the collision energy, thereby effectively protecting the safety of the guardrail and the vehicle, and the waste tire can be recycled. After the collision, the tire returns to its original position with the support cage.

[0004] In this patent, the waste tire is fixed to the limiting ring by means of a strap or glue. The strap connection method requires the staff to process the waste tire to form a number of connection holes, and then pass the strap through the connection holes to fix the waste tire, so it is inconvenient to install the waste tire. Although the glue bonding method has a fast installation speed, it is inconvenient to disassemble and replace the waste tire.

[0005] Therefore, we made improvements to this and proposed a bridge-tunnel transition section protection device based on waste tires. Utility Model Content

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] Example:

[0026] Reference Figure 1-5 A bridge-tunnel transition section protection device based on waste tires includes a protection plate 1 and several waste tires 2 arranged on one side of the protection plate 1, and several connecting components 3 are arranged on the side of the protection plate 1 away from the waste tires 2.

[0027] The connecting assembly 3 includes a plurality of springs 31 fixedly connected to one side of the protective plate 1, and the ends of the plurality of springs 31 away from the protective plate 1 are commonly fixedly connected to a driven plate 32. The spring 31 is a hard spring 31 and is difficult to bend, so that the driven plate 32 will not rotate. A plurality of slides 33 are provided on one side of the driven plate 32, and a limit rod 34 is fixedly connected to the slide 33. A sliding plate 35 is slidingly sleeved on the outer circumference of the limit rod 34. A plurality of slide grooves 36 are provided on the side wall of the protective plate 1, and the sliding plates 35 pass through the corresponding slide grooves 36. A pressure plate 37 is fixedly connected to the end of the sliding plate 35 close to the waste tire 2, and the pressure plate 37 and the corresponding sliding plate 35 are arranged perpendicularly. A limit plate 38 is provided in the slide 33, and a driving part 39 is provided on one side of the driven plate 32.

[0028] In the initial state, the spring 31 is in a natural state, the distance between each sliding plate 35 is small, and when the waste tire 2 is placed, the plurality of pressing plates 37 are all located in the central opening of the waste tire 2. The corresponding plurality of sliding plates 35 are evenly arranged in an annular shape.

[0029] like Figure 1-5 As shown, as a preferred embodiment, on the basis of the above method, further, the driving part 39 includes a driving plate 391 located on one side of the driven plate 32, and a square rod 392 is fixedly connected to one side of the driving plate 391, and the square rod 392 slides through the driven plate 32, and a plurality of connecting rods 393 are hinged on the outer surface of the square rod 392, and the end of the connecting rod 393 away from the square rod 392 is hinged to the corresponding sliding plate 35, and a screw 394 is rotatably connected to one side of the protective plate 1, and the screw 394 is threadedly connected to the driving plate 391.

[0030] When installing the waste tire 2, the waste tire 2 is placed against the sidewall of the protective plate 1, and the plurality of pressure plates 37 are positioned within the central opening of the waste tire 2. The screw 394 is then rotated, which drives the drive plate 391 away from the protective plate 1. The drive plate 391 then drives the square rod 392, which in turn drives the connecting rod 393, which in turn drives the sliding plate 35, which in turn drives the pressure plates 37, gradually inserting the pressure plates 37 into the waste tire 2. The sliding plates 35 contact the stop plate 38, preventing them from sliding further within the slideway 33. The screw 394 is then rotated further, driving the square rod 392, connecting rod 393, sliding plate 35, pressure plates 37, and driven plate 32 to move synchronously. The spring 31 is then stretched, causing the pressure plates 37 to gradually approach the protective plate 1, ultimately pressing the waste tire 2 against the protective plate 1, thus completing the installation of the waste tire 2.

[0031] When removing the waste tire 2, it is only necessary to rotate the lead screw 394 in the opposite direction.

[0032] like Figure 5 As shown, as a preferred embodiment, based on the above method, further, the front and rear side walls of the sliding plate 35 are both in contact with the inner wall of the corresponding sliding groove 36, so the sliding plate 35 will not rotate relative to the limiting rod 34.

[0033] like Figure 3-4 As shown, as a preferred embodiment, based on the above-mentioned method, further, the limit plate 38 is slidably connected to the corresponding limit rod 34, and a screw rod 4 is provided on the outer peripheral surface of the driven plate 32. The screw rod 4 is threadedly connected to the corresponding driven plate 32. The screw rod 4 partially extends into the corresponding slideway 33, and one end of the screw rod 4 located in the slideway 33 is rotatably connected to the corresponding limit plate 38. By rotating the screw rod 4, the limit plate 38 can be driven to move, thereby adjusting the distance that the sliding plate 35 moves along the limit rod 34, so that the pressure plate 37 can be inserted into waste tires 2 with different inner diameters. Therefore, the device can install waste tires 2 with different inner diameters, thereby improving the applicability of the device.

[0034] Specifically, when the bridge-tunnel transition section protection device based on waste tires 2 is used: the protective plate 1 is fixed to the roadside of the bridge-tunnel transition section, and then the waste tire 2 is attached to the side wall of the protective plate 1, and several pressure plates 37 are all located in the central opening of the waste tire 2, and then the screw 394 is rotated, and the screw 394 rotates to drive the driving plate 391 to move in the direction away from the protective plate 1, and the driving plate 391 drives the square rod 392 to move, the square rod 392 drives the connecting rod 393 to move, the connecting rod 393 drives the sliding plate 35 to move, and the sliding plate 35 drives the pressure plate 37 to move, so that the pressure plate 37 is gradually inserted into the interior of the waste tire 2. Until the sliding plate 35 contacts the limit plate 38, the sliding plate 35 can no longer slide in the slideway 33, and the lead screw 394 continues to rotate, driving the square rod 392, the connecting rod 393, the sliding plate 35, the pressure plate 37 and the driven plate 32 to move synchronously. The spring 31 is stretched, so that the pressure plate 37 gradually approaches the protective plate 1, and finally presses the waste tire 2 onto the protective plate 1, completing the installation of the waste tire 2.

[0035] When the waste tire 2 is to be removed, the lead screw 394 only needs to be rotated in the reverse direction to move the pressure plate 37 away from the protective plate 1 until the spring 31 returns to its natural state. The lead screw 394 is then continued to be rotated to retract the pressure plate 37 from the inside of the waste tire 2 into the central opening of the waste tire 2, and the waste tire 2 can then be removed.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
