Description

Technical Field

[0001] The present invention relates to the technical field of bridge engineering, and in particular to an expansion joint maintenance device used in bridge engineering. Background Art

[0002] During their use, bridges are subject to a variety of factors, such as temperature fluctuations, vehicle loads, concrete shrinkage and creep, which can cause deformation in the bridge structure. Expansion joints adapt to these deformations, ensuring that the bridge can continue to function properly despite these deformations.

[0003] The proper functioning of expansion joints is crucial for bridges. Without them, bridges can experience cracks or uneven settlement during deformation, significantly impacting vehicle traffic. Expansion joints ensure smooth movement across bridges, reducing bumps and improving driving comfort and safety.

[0004] Therefore, expansion joints require regular maintenance. For example, debris, such as leaves, dirt, and gravel, must be regularly removed from the expansion joints to prevent accumulation that could affect their normal expansion and contraction. The condition of the expansion joint sealant must also be regularly checked. If signs of aging, cracking, or peeling are detected, repair or replacement should be carried out promptly. Prolonged exposure to sunlight and humidity can accelerate sealant aging. Frequent inspections and maintenance consume considerable manpower and resources, yet these inspections and maintenance are essential. Therefore, if expansion joints can be made to perform a certain level of self-maintenance during daily operation to extend their service life and prolong maintenance cycles, significant savings can be achieved.

[0024] The present invention arranges the side beam 1 to move laterally to match the deformation of the bridge, and stretches or squeezes the sealing strip 104 when the side beam 1 moves laterally, causing it to expand and contract to match the lateral movement of the side beam 1, and passively drives the maintenance component to move during the lateral movement to maintain the sealing strip 104.

[0027] As a further preferred scheme in the embodiment of the present invention, the maintenance component includes a middle plate 4 fixedly connected to the side surface of the support frame 201, and a sliding groove 401 is provided on the middle plate 4, and a sliding bar 402 is slidingly connected in the sliding groove 401, and a first connecting rod 504 is fixedly connected to the side surface of the sliding bar 402, and one end of the first connecting rod 504 is rotatably connected to the second connecting rod 505, and one end of the second connecting rod 505 is rotatably connected to the third connecting rod 506, and one end of the third connecting rod 506 is fixedly connected to the inner surface of the side beam 1.

[0028] Furthermore, the connection between the sliding bar 402 and the first connecting rod 504 is located below the sliding slot 401 .

[0029] Furthermore, when the first connecting rod 504, the second connecting rod 505 and the third connecting rod 506 are in a line, they move to the outermost end.

[0030] As a further preferred solution in the embodiment of the present invention, the maintenance component also includes a first connecting bar 5 fixedly connected to the upper surface of the middle plate 4, and the surface of the first connecting bar 5 is slidably sleeved with a first slide bar 501, and one side surface of the first slide bar 501 is fixedly connected with a second connecting bar 502, and the surface of the second connecting bar 502 is slidably sleeved with a second slide bar 503, and one end of the second slide bar 503 is fixedly connected to the inner surface of the side beam 1.

[0031] Furthermore, the second slide bar 503 slides on the second connecting bar 502 , and the first slide bar 501 slides on the first connecting bar 5 to cooperate with the side beam 1 to translate.

[0032] Furthermore, the first connecting rod 504 , the second connecting rod 505 , the third connecting rod 506 , the first connecting bar 5 , the first sliding bar 501 , the second connecting bar 502 and the second sliding bar 503 are all made of reinforcing rib material.

[0033] Specifically, when the side beam 1 moves outward in translation, the second slide bar 503 slides on the second connecting bar 502, and the first slide bar 501 slides on the first connecting bar 5 to cooperate with the translation of the side beam 1, and pulls the third connecting rod 506 during the translation to drive the second connecting rod 505 to rotate relative to the first connecting rod 504, thereby driving the sliding bar 402 to slide in the sliding groove 401.

[0034] As a further preferred solution in the embodiment of the present invention, the maintenance component also includes a telescopic groove arranged on the lower surface of the sliding bar 402, and the telescopic bar 403 is slidably connected in the telescopic groove, and the lower surface of the telescopic bar 403 is connected to a maintenance brush plate 404 and a maintenance box 405, and the lower end of the maintenance box 405 is provided with a liquid outlet groove, and a rolling ball 407 is slidably arranged in the liquid outlet groove, and a liquid filling valve 406 is provided on the side wall of the maintenance box 405.

[0036] Furthermore, a rubber maintenance agent is injected into the maintenance box 405 through the injection valve 406 .

[0037] Specifically, when the sliding bar 402 slides in the sliding groove 401, it drives the maintenance brush plate 404 to move to remove debris from the seam of the sealing strip 104, and the surface of the sealing strip 104 squeezes the rolling ball 407 to make it slide inward, so that the rubber maintenance agent in the liquid tank flows out to the surface of the sealing strip 104. Under the movement of the maintenance brush plate 404, the rubber maintenance agent is evenly spread to maintain the sealing strip 104.

[0038] As a further preferred solution in the embodiment of the present invention, a displacement box 6 is fixedly connected to the lower surface of the side beam 1, a displacement groove 602 is provided on the side wall of the displacement box 6, a clamping support 603 is provided on the upper surface inside the displacement groove 602, a pressure-bearing support 604 is provided on the lower surface inside the displacement groove 602, and a pressure-bearing slide groove 605 is provided on the upper surface of the pressure-bearing support 604.

[0039] Furthermore, the pressing support 603 is made of rubber material to press the support beam 7 .

[0040] As a further preferred solution in the embodiment of the present invention, the lower surface of the middle beam 202 is connected to the support beam 7, and the lower surface of the support beam 7 is provided with a sliding steel plate 701, which is slidably connected to the pressure-bearing slide groove 605.

[0041] Specifically, when the side beam 1 translates, it drives the displacement box 6 to move synchronously to both sides, so that the pressure bearing 604 slides to both sides under the support beam 7 to cooperate with the translation of the side beam 1, thereby providing support force for the structure thereon at all times.

[0042] As a further preferred solution in the embodiment of the present invention, a second limit block 702 is provided on one side surface of the support beam 7, and a first limit block 606 is provided on one side surface inside the displacement box 6. The first limit block 606 and the second limit block 702 are at the same horizontal position.

[0043] Specifically, when the side beam 1 translates to the maximum limit, the first limit block 606 and the second limit block 702 abut against each other to limit the side beam 1 from further translation, thereby preventing the sealing strip 104 from being torn due to excessive translation.

[0044] As a further preferred solution in the embodiment of the present invention, the outer surface of the side beam 1 is fixedly connected to an anchor plate 102, the anchor plate 102 is fixedly connected to an anchor bar 103, and the side surface and lower surface of the displacement box 6 are each fixedly connected to an anchor bolt 601.

[0045] Specifically, the anchor plate 102, the anchor bar 103 and the anchor bolt 601 strengthen the connection strength between the expansion joint and the bridge.

[0046] As a further preferred solution in the embodiment of the present invention, the upper end of the support frame 201 is fixedly connected to the top plate 2.

[0047] Specifically, the top plate 2 prevents the maintenance assembly from being crushed by the vehicle and blocks part of the sunlight to prevent the sunlight from directly hitting the seam of the sealing strip 104 and causing the sealing strip 104 to age faster.

[0048] As a further preferred solution in the embodiment of the present invention, a sewage hopper 3 is provided on the upper surface of the end of the center beam 202 , and a sewage pipe 301 is connected to the lower surface of the sewage hopper 3 .

[0049] Specifically, the removed debris is swept into the sewage hopper 3 and discharged under the bridge through the sewage pipe 301 to prevent the debris from accumulating under the expansion joint.

[0050] In the present invention, an expansion joint maintenance device for bridge engineering is arranged at the connection of the bridge. The anchor plate 102, the anchor bar 103 and the anchor bolt 601 strengthen the connection strength between the expansion joint and the bridge. When the bridge is used daily, when the bridge structure is deformed due to factors such as temperature changes, vehicle loads, concrete shrinkage and creep, the side beam 1 is moved laterally to cooperate with the deformation of the bridge; when the side beam 1 moves outward in translation, the second slide bar 503 slides on the second connecting bar 502, and the first slide bar 501 slides on the first connecting bar 5 to cooperate with the translation of the side beam 1, and pulls the third connecting rod 506 during the translation to drive the second connecting rod 505 relative to the first connecting rod. The rod 504 rotates, causing the sliding bar 402 to be driven to slide in the sliding groove 401, thereby driving the maintenance brush plate 404 to move to remove debris in the seam of the sealing strip 104, and the surface of the sealing strip 104 squeezes the rolling ball 407 to slide inward, so that the rubber maintenance agent in the liquid tank flows out to the surface of the sealing strip 104, and the rubber maintenance agent is evenly applied under the movement of the maintenance brush plate 404 to maintain the sealing strip 104; when the side beam 1 translates, it will also synchronously drive the displacement box 6 to move synchronously to both sides, so that the pressure bearing 604 slides to both sides under the support beam 7 to cooperate with the translation of the side beam 1, thereby providing support force for the structure thereon at all times.
