Description

Technical Field

[0001] The invention belongs to the technical field of bridge expansion joints, and in particular relates to a low-noise bridge expansion joint structure with a buffering effect. Background Art

[0002] Bridge expansion joints are devices used in bridge structures to handle deformation caused by temperature changes, settlement and other displacements. Bridge materials expand or contract when the temperature changes, and expansion joints allow this movement to prevent stress concentration and structural damage caused by temperature changes. Due to factors such as foundation settlement, traffic loads or earthquakes, bridges may experience relative displacement. Expansion joints can adapt to these displacements and maintain the stability of the bridge. When a vehicle passes over an expansion joint at a higher speed, the impact and collision will increase, which can easily lead to loud noise.

[0003] Over time, the materials of expansion joints (such as rubber or sealing materials) will age due to ultraviolet rays, temperature changes and environmental influences, causing their elasticity to decrease, thereby causing the gap to widen, making it easier for dirt and rainwater to enter. After rainwater flows into the gap, it is difficult to drain. Long-term retention may cause corrosion, especially adverse effects on metal parts and concrete structures. At the same time, the accumulation of garbage and moisture makes the maintenance of expansion joints more complicated. Cleaning requires professional equipment, which increases maintenance costs and human resources. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a low-noise bridge expansion joint structure with a buffering effect.

[0005] The technical solution adopted to solve the above technical problems is: a low-noise bridge expansion joint structure with a buffering effect, including a bridge connecting frame, on which a first expansion joint and a second expansion joint are respectively installed, and the first expansion joint and the second expansion joint are slidingly connected, and mounting grooves are symmetrically opened in the bridge connecting frame, and a plurality of buffering low-noise structures are installed in the mounting grooves; one end of the bridge connecting frame is fixedly connected to a left mounting frame, and the end of the bridge connecting frame away from the left mounting frame is fixedly connected to a right mounting frame, a water and sewage diversion structure is installed in the bridge connecting frame, and the first sliding groove and the second sliding groove are respectively opened in the bridge connecting frame.

[0006] Through the above technical scheme, the water and sewage diversion structure can effectively guide rainwater to flow out and prevent water from being retained in the gap, thereby reducing corrosion and aging of the expansion joint material, reducing the accumulation of garbage and debris in the gap, and keeping the expansion joint clean.

[0007] Furthermore, a rainwater collecting groove is provided at the lower end of the bridge connecting frame, an installation pipe is fixedly connected to the left mounting frame, the installation pipe and the rainwater collecting groove are interconnected, a material receiving box is provided on the left mounting frame, an installation handle is fixedly connected to the upper end of the material receiving box, and a rubber anti-slip pad is fixedly connected to the installation handle.

[0008] Through the above technical solution, when rainwater and garbage flow into the bridge through the expansion joint, the rainwater all enters the rainwater collecting trough through the downhole. When the staff needs to reuse the rainwater in the rainwater collecting trough, they can connect the installation pipe with a hose and open the valve to take out the rainwater in the rainwater collecting trough.

[0009] Furthermore, the buffering and low-noise structure includes a mounting base fixedly connected to the bridge connecting frame, the lower surfaces of the first telescopic joint and the second telescopic joint are respectively fixedly connected with mounting cylinders, the mounting cylinders are slidably connected to the first sliding groove, the upper surface of the mounting base is fixedly connected with a fixing piece, a connecting column is slidably connected in the fixing piece, an oblique slot is opened in the connecting column, an oblique slot is slidably connected with an oblique column, and the first slide and the second slide are respectively fixedly connected at both ends of the mounting tube.

[0010] Furthermore, a connecting head is fixedly installed on the upper end of the connecting column, a first spring is arranged on the connecting head, and two ends of the first spring are respectively fixedly connected to the mounting tube and the connecting head.

[0011] Through the above technical solution, the second telescopic joint and the first telescopic joint press the installation cylinder downward, and the installation cylinder moves downward while driving the first slide and the second slide to move up. When the first slide and the second slide move up, the wedge surface and the wedge surfaces at both ends of the inclined column slide against each other, so that the inclined column drives the connecting column to slide upward, thereby squeezing the first spring.

[0012] Furthermore, both ends of the inclined column are wedge-shaped, and the inclined column is slidably connected to the first slide and the second slide.

[0013] Furthermore, the water and sewage diversion structure includes a connecting shaft fixedly connected to the bridge connecting frame, a sliding plate is rotatably connected to the connecting shaft, a plurality of drainage holes are provided on the sliding plate, and a connecting block is fixedly connected to one end of the sliding plate near the right mounting frame, a positioning groove is provided on the connecting block, a limiting shaft is slidably connected in the positioning groove, one end of the limiting shaft is fixedly connected to a fixing column, and a limiting hole is provided in the right mounting frame.

[0014] Through the above technical solution, when the second spring loses pressure, it can instantly push the fixed column to slide upward, so that the limit shaft drives the connecting block to rotate. At this time, the sliding plate rotates back to its original position under the clockwise action of the second spring and generates vibration, thereby shaking off the remaining garbage on the sliding plate.

[0015] Furthermore, one end of the fixing column is fixedly connected to a connecting piece, and the upper end of the connecting piece is fixedly connected to a pedal.

[0016] Furthermore, a plurality of anti-skid grooves are provided on the pedal, the fixed column is slidably connected to the limiting hole, a second spring is fixedly connected to the lower end of the fixed column, and the lower end of the second spring is fixedly connected to the right mounting frame.

[0017] The beneficial effects of the present invention are as follows: (1) The present invention can effectively guide rainwater to flow out and prevent water from being retained in the gap by designing a water and sewage diversion structure and a pedal to be used in conjunction with each other, thereby reducing corrosion and aging of the expansion joint material, reducing the accumulation of garbage and debris in the gap, keeping the expansion joint clean, and extending its service life; (2) The present invention adopts the mutual sliding between the wedge surface and the wedge surfaces at both ends of the inclined column when the first slide and the second slide move up, so that the inclined column drives the connecting column to slide upward, thereby squeezing the first spring, so that the force generated by the buffering and low-noise structure when the vehicle passes through the expansion joint of the bridge is decomposed and weakened, which can effectively absorb and reduce the noise generated by the vehicle passing through the expansion joint, thereby improving the comfort of the surrounding environment. At the same time, the buffering and low-noise structure can also reduce the direct impact of the vehicle on the expansion joint, thereby reducing wear and fatigue and extending the service life of the expansion joint and its surrounding structures.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] like Figure 1-Figure 2 As shown, a low-noise bridge expansion joint structure with a buffering effect in this embodiment includes a low-noise bridge expansion joint structure with a buffering effect, including a bridge connecting frame 1, on which a first expansion joint 11 and a second expansion joint 12 are respectively installed, and the first expansion joint 11 and the second expansion joint 12 are slidingly connected, and mounting grooves 14 are symmetrically opened in the bridge connecting frame 1, and a plurality of buffering low-noise structures 4 are installed in the mounting grooves 14; one end of the bridge connecting frame 1 is fixedly connected to a left mounting frame 2, and the end of the bridge connecting frame 1 away from the left mounting frame 2 is fixedly connected to a right mounting frame 3, and a water and sewage diversion structure 5 is installed in the bridge connecting frame 1, and a first sliding groove 15 and a second sliding groove 16 are respectively opened in the bridge connecting frame 1, and the water and sewage diversion structure 5 can effectively guide rainwater to flow out and prevent water from being retained in the gap, thereby reducing corrosion and aging of the expansion joint material, reducing the accumulation of garbage and debris in the gap, and keeping the expansion joint clean.

[0027] like Figure 1-Figure 6As shown, a rainwater receiving groove 13 is provided at the lower end of the bridge connecting frame 1, and an installation pipe 21 is fixedly connected to the left mounting frame 2. The installation pipe 21 and the rainwater receiving groove 13 are interconnected. A material collecting box 22 is provided on the left mounting frame 2, and an installation handle 23 is fixedly connected to the upper end of the material collecting box 22. A rubber anti-skid pad is fixedly connected to the installation handle 23. When rainwater and garbage flow into the bridge through the expansion joint, the rainwater all enters the rainwater receiving groove 13 through the downhole 52. When the staff needs to reuse the rainwater in the rainwater receiving groove 13, a hose is connected to the installation pipe 21, and the rainwater in the rainwater receiving groove 13 can be taken out by opening the valve.

[0028] like Figure 1-Figure 4 As shown, the buffer low-noise structure 4 includes a mounting base 40 fixedly connected to the bridge connecting frame 1, the lower surfaces of the first telescopic section 11 and the second telescopic section 12 are respectively fixedly connected with mounting cylinders 46, the mounting cylinders 46 are slidably connected to the first sliding groove 15, the upper surface of the mounting base 40 is fixedly connected with a fixing member 48, a connecting column 41 is slidably connected in the fixing member 48, an oblique slot 42 is provided in the connecting column 41, an oblique column 43 is slidably connected in the oblique slot 42, and the two ends of the mounting cylinder 46 are respectively fixedly connected with a first slide 47 and a second slide 49; a connecting head 44 is fixedly installed on the upper end of the connecting column 41, and the connecting head 4 4 is provided with a first spring 45, and the two ends of the first spring 45 are fixedly connected to the mounting cylinder 46 and the connecting head 44 respectively. The second telescopic section 12 and the first telescopic section 11 press the mounting cylinder 46 downward, and the mounting cylinder 46 moves downward while driving the first slide 47 and the second slide 49 to move upward. When the first slide 47 and the second slide 49 move upward, the wedge surface and the wedge surfaces at both ends of the inclined column 43 slide with each other, so that the inclined column 43 drives the connecting column 41 to slide upward, thereby squeezing the first spring 45; the two ends of the inclined column 43 are respectively wedge-shaped, and the inclined column 43 is slidably connected with the first slide 47 and the second slide 49.

[0029] like Figure 1-Figure 6 As shown, the sewage diversion structure 5 includes a connecting shaft 53 fixedly connected to the bridge connecting frame 1, and a sliding plate 51 is rotatably connected to the connecting shaft 53, and a plurality of water drop holes 52 are provided on the sliding plate 51. The sliding plate 51 is fixedly connected to a connecting block 55 near one end of the right mounting frame 3, and a positioning groove 56 is provided on the connecting block 55. A limiting shaft 57 is slidably connected in the positioning groove 56, and one end of the limiting shaft 57 is fixedly connected to the fixed column 32. A limiting hole 31 is provided in the right mounting frame 3. When the second spring 54 loses pressure, it can instantly push the fixed column 32 to slide upward, so that the limiting shaft 57 drives the connecting block 55 to rotate. At this time, the sliding plate 51 rotates back to its original position under the clockwise action of the second spring 54 and generates vibration, thereby shaking off the remaining garbage on the sliding plate 51.

[0030] like Figure 1-Figure 5As shown, one end of the fixed column 32 is fixedly connected to a connecting piece 33, and the upper end of the connecting piece 33 is fixedly connected to a pedal board 34; a plurality of anti-slip grooves are provided on the pedal board 34, and the fixed column 32 is slidably connected to the limiting hole 31, and the lower end of the fixed column 32 is fixedly connected to a second spring 54, and the lower end of the second spring 54 is fixedly connected to the right mounting frame 3.

[0031] The working principle of this embodiment is as follows: when the maintenance personnel need to clean up the garbage in the expansion joint, they step on the pedal 34 downward, and the pedal 34 drives the fixed column 32 to slide downward through the connecting piece 33. The fixed column 32 compresses the second spring 54 downward and drives the limit shaft 57 to move downward. Since the limit shaft 57 is limited in the positioning groove 56, the connecting block 55 is driven to rotate, and the connecting block 55 drives the sliding plate 51 to rotate around the connecting shaft 53. At this time, the pedal 34 is released, the second spring 54 loses pressure, and the sliding plate 51 is instantly released. Push the fixed column 32 to slide upward, so that the limit shaft 57 drives the connecting block 55 to rotate. At this time, the sliding plate 51 is rotated back to its original position by the clockwise action of the second spring 54 and vibrates at the same time, so that the remaining garbage on the sliding plate 51 is shaken off and all slides along the sliding plate 51 into the collecting box 22. After repeating the operation several times, the maintenance personnel can collect all the garbage on the sliding plate 51 into the collecting box 22. The maintenance personnel pull up the collecting box 22 from the left mounting frame 2 through the installation handle 23, which is convenient for centralized treatment of garbage.

[0032] When rainwater and garbage flow into the bridge through the expansion joint, all the rainwater enters the rainwater receiving trough 13 through the downspout 52. When the staff needs to reuse the rainwater in the rainwater receiving trough 13, they can use a hose to connect the installation pipe 21 and open the valve to take out the rainwater in the rainwater receiving trough 13.

[0033] When the vehicle passes through the expansion joint, the second expansion joint 12 and the first expansion joint 11 press the mounting cylinder 46 downward, and the mounting cylinder 46 moves downward while driving the first slide 47 and the second slide 49 upward. When the first slide 47 and the second slide 49 move upward, the wedge surfaces and the wedge surfaces at both ends of the inclined column 43 slide against each other, so that the inclined column 43 drives the connecting column 41 to slide upward, thereby squeezing the first spring 45, so that the force generated when the vehicle passes through the expansion joint of the bridge can be decomposed and weakened.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention.
