Abstract
Description
Technical Field
[0001] This utility model relates to the field of road, bridge and tunnel technology, specifically a road, bridge and tunnel connection device with a protective structure. Background Technology
[0002] Roads, bridges, and tunnels refer to structures used in road construction to cross obstacles (such as rivers and canyons) or pass through obstacles (such as mountains and seabeds). Specifically, bridges are structures erected on the ground to cross obstacles, allowing vehicles and pedestrians to pass; tunnels are passageways excavated underground or inside mountains for roads or railways to cross obstacles. To prevent cracks or damage to the structure due to changes in climate and temperature (thermal expansion and contraction), a structural joint, also known as an expansion joint, is set at an appropriate location along the construction joint direction of the building or structure.
[0003] Existing expansion joints, while capable of drainage during rainy weather, suffer from waterlogging. Rainwater carries mud and other debris into the joints, clogging the drainage pipes and causing water accumulation. Prolonged water accumulation accelerates corrosion of the steel plates within the expansion joints. Furthermore, the clogged drainage pipes contribute to road surface flooding, increasing the risk of vehicles skidding and causing traffic accidents. Therefore, we propose a road bridge-tunnel connection device with a protective structure. Utility Model Content
[0004] The purpose of this utility model is to provide a road bridge and tunnel connection device with a protective structure to solve the problem mentioned in the background art that rainwater carries mud and foreign matter into the expansion joint and blocks the drainage pipe, causing water accumulation to erode the internal steel plate and the road surface, which makes it easy for vehicles to slip and cause traffic accidents.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a road bridge and tunnel connection device with a protective structure, comprising: a carrier body, guardrails fixedly connected to both sides of the top of the carrier body, a filter plate slidably connected inside the carrier body, a water outlet pipe fixedly connected to the outside of the carrier body, multiple baffles slidably connected inside the carrier body, and multiple locking mechanisms provided inside the carrier body.
[0006] The locking mechanism includes a housing, the outer side of which is fixedly connected to the inside of the carrier, a locking block is slidably connected inside the housing, a spring is sleeved on the outer side of the locking block, a sliding block is fixedly connected to the outer side of the locking block, a shell is fixedly connected to the top of the housing, a connecting block is slidably connected inside the shell, and a stop block is fixedly connected to the bottom of the connecting block.
[0007] The top of the baffle is fixedly connected with a protrusion.
[0008] One end of the spring is fixedly connected to the inner wall of the outer casing, and the other end of the spring is fixedly connected to the outer side of the sliding block.
[0009] The outer side of the sliding block is slidably connected to the inside of the outer shell, and the sliding block and the stop block abut against each other.
[0010] The end of the locking block away from the sliding block is fixedly connected to a pull column, and the locking block passes through the outer shell and is inserted into the filter plate.
[0011] The outer side of the stop block is slidably connected to the inside of the housing, and the outer side of the stop block is slidably connected to the inside of the outer shell.
[0012] This utility model has at least the following beneficial effects:
[0013] In use, this utility model filters and blocks mud and foreign objects carried by rainwater through a filter plate, preventing them from clogging the drainage pipes inside the expansion joint. A snap-fit mechanism allows the filter plate to be disassembled and the blocked mud and foreign objects removed, preventing blockage and drainage problems. This design effectively filters and blocks mud and foreign objects carried by rainwater, and the filter plate can be disassembled and cleaned to prevent blockage of the drainage pipes inside the expansion joint, which could lead to water accumulation that could corrode the steel plates inside the expansion joint and cause vehicles to slip, resulting in traffic accidents.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Example 1
[0022] Please see Figures 1 to 5 This utility model provides a technical solution: a road bridge and tunnel connection device with a protective structure, comprising: a load-bearing body 1, guardrails 2 fixedly connected to both sides of the top of the load-bearing body 1, a filter plate 3 slidably connected inside the load-bearing body 1, a water outlet pipe 4 fixedly connected to the outside of the load-bearing body 1, multiple baffles 5 slidably connected inside the load-bearing body 1, and multiple locking mechanisms 6 provided inside the load-bearing body 1. When it rains, rainwater carrying mud and foreign objects flows into the expansion joint. The filter plate 3 filters and blocks the mud and foreign objects, preventing them from entering the drainage pipe inside the expansion joint and clogging the drainage pipe. The filtered and blocked rainwater is discharged through the water outlet pipe 4. Opening the baffles 5 allows operation of the locking mechanisms 6. By setting the locking mechanisms 6, the filter plate 3 can be disassembled and cleaned to prevent the filter plate 3 from clogging and affecting drainage.
[0023] The locking mechanism 6 includes a housing 60, which is fixedly connected to the outside of the carrier 1. A locking block 61 is slidably connected inside the housing 60, and a spring 62 is sleeved on the outside of the locking block 61. A sliding block 63 is fixedly connected to the outside of the locking block 61. A housing 65 is fixedly connected to the top of the housing 60, and a connecting block 66 is slidably connected inside the housing 65. A stop block 67 is fixedly connected to the bottom of the connecting block 66. In use, pulling the locking block 61 causes it to slide out from inside the filter plate 3 and into the housing 60. The locking block 61 drives the sliding block 63 to slide inside the housing 60. When the sliding block 63 slides, it compresses the spring 62, causing... Spring 62 generates elastic force. After sliding block 63 slides, the stop block 67 inside housing 65 loses support and slides down, abutting against sliding block 63 to prevent the stop block 61 from automatically resetting after being released. At this time, filter plate 3 can be removed to clean the dirt and foreign objects on the surface. After cleaning, when installing filter plate 3, slide filter plate 3 into the carrier 1 and pull connecting block 66. Connecting block 66 drives stop block 67 to slide into housing 65. Sliding block 63 is pushed by spring 62. Sliding block 63 drives stop block 61 to re-insert into filter plate 3. The top of sliding block 63 and the bottom of stop block 67 abut against each other to prevent stop block 67 from sliding down.
[0024] Example 2
[0025] In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that a protrusion 7 is fixed to the top of the baffle 5. The protrusion 7 is used to facilitate opening the baffle 5. One end of the spring 62 is fixed to the inner wall of the outer shell 60 and the other end is fixed to the outer side of the sliding block 63, so that the spring 62 can be compressed to provide elastic force. The outer side of the sliding block 63 slides inside the outer shell 60, so that the sliding block 63 slides stably. The sliding block 63 and the stop block 67 abut against each other to prevent the sliding block 63 from being pushed back by the spring 62. A pull post 64 is fixed to the end of the locking block 61 away from the sliding block 63. The pull post 64 is used to facilitate pulling the locking block 61. The locking block 61 passes through the outer shell 60 and is inserted into the inside of the filter plate 3, so that the filter plate 3 is stably installed. The outer side of the stop block 67 slides inside the outer shell 65, so that the stop block 67 can slide stably. The outer side of the stop block 67 slides inside the outer shell 60, so that the stop block 67 slides stably.
