Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology; specifically, this utility model relates to a guide device for laying carbon fiber cloth for reinforcing bridge bottom slabs. Background Technology

[0002] When reinforcing the bridge base slab, since the bridge bottom is located within the river channel, it is not possible to erect scaffolding for construction. Bridge inspection vehicles are often used, and construction workers stand in the basket on the bridge inspection vehicle to reinforce the bridge base slab. Bridge reinforcement mainly involves sealing some gaps in the bridge base slab. The sealing work uses carbon fiber cloth to seal the cracks.

[0003] When applying carbon fiber cloth, it is important to ensure that the cloth is as straight as possible. The current method of applying carbon fiber cloth requires two workers to work together. One worker applies adhesive to the area to be covered on the bridge bottom, and the other worker applies the carbon fiber cloth to the area with adhesive and removes any remaining air bubbles. However, when applying carbon fiber cloth manually, one can only rely on the naked eye to judge whether the cloth is straight, and there is a lack of support for the unattached areas, which makes it impossible to guarantee the straightness of the cloth during the application process. Utility Model Content

[0004] In view of this, the present invention provides a guide device for laying carbon fiber cloth for reinforcing bridge underplate, thereby solving or at least alleviating the above-mentioned problems existing in the prior art.

[0005] To achieve the aforementioned objectives, this utility model provides a guide device for laying carbon fiber cloth for reinforcing bridge abutment plates, comprising:

[0006] Two calibration plates are set in parallel, and the distance between the two calibration plates is adapted to the width of the carbon fiber cloth, so as to rest against the bridge bottom plate.

[0007] Two limiting plates are provided, located on the front side of the two calibration plates respectively, and the limiting plates are connected to the calibration plates. The distance between the two limiting plates is adapted to the width of the carbon fiber cloth.

[0008] A support roller, positioned between two limiting plates, is used to support the unattached carbon fiber cloth, and the top height of the support roller is less than the top height of the calibration plate.

[0009] Optionally, the bridge abutment reinforcement carbon fiber cloth laying guide device described above may also include:

[0010] A connecting plate corresponding to each limiting plate connects the limiting plate and the calibration plate on the same side. When the limiting plate contacts the bridge bottom plate, the connecting plate is parallel to the bridge bottom plate.

[0011] A pressing roller is positioned between two connecting plates. The pressing roller and the connecting plates slide together along the length of the connecting plates. The top of the pressing roller can press the carbon fiber cloth against the bridge bottom plate, and the carbon fiber cloth is bonded by sliding along the length of the connecting plates.

[0012] Optionally, the bridge abutment reinforcement carbon fiber cloth laying guide device described above may also include:

[0013] There are two rotating plates, located on opposite sides of the two limiting plates, and rotatably connected to the limiting plates;

[0014] A pressing head is positioned between two rotating plates. The pressing head slides with the rotating plates along the length of the rotating plates and is used to clamp the unattached carbon fiber cloth in conjunction with the support roller.

[0015] When the pressing head slides to the state of clamping the carbon fiber cloth, the rotating plate can swing downward to straighten the unattached carbon fiber cloth.

[0016] Optionally, the bridge abutment reinforcement carbon fiber cloth laying guide device described above may also include:

[0017] The base is clamped and installed on top of the basket;

[0018] A bracket is mounted on the top of the base. The bracket slides along the length of the base and is fixedly connected to the calibration plate to align the calibration plate with the carbon fiber cloth.

[0019] In the aforementioned guide device for laying carbon fiber cloth to reinforce bridge underplate, optionally, the connecting plate is rotatably connected to the top of the bracket, and the end of the connecting plate near the limiting plate swings upward to make the limiting plate contact the bridge underplate.

[0020] Optionally, the bridge abutment reinforcement carbon fiber cloth laying guide device described above may also include:

[0021] Two locking rods are provided on both sides of the bracket. The locking rods are parallel to the bracket and slide in the bracket along their length. The top of the locking rod slides in the end of the connecting plate.

[0022] A limiting block corresponding to each locking rod is provided at the bottom of the locking rod. The limiting block can prevent the rod from moving in the length direction. The bottom end of the limiting block can contact the base to lock the bracket and the base in the lateral direction.

[0023] This utility model discloses a carbon fiber cloth laying guide device for reinforcing bridge underplate. It uses a calibration plate aligned with the already pasted carbon fiber cloth, a limiting plate parallel to the calibration plate, and a support roller supporting the unpaved carbon fiber cloth. The limiting plate contacts the bridge underplate, which can guide the unpaved carbon fiber cloth. When the limiting plate supports the bridge underplate, a pressing head is used to straighten the unpaved carbon fiber cloth, which facilitates the subsequent pasting of the unpaved carbon fiber cloth to the bridge underplate.

[0031] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] like Figures 1 to 5 As shown, a typical embodiment of this utility model provides a guide device for laying carbon fiber cloth for reinforcing bridge abutment plates, comprising:

[0033] Two calibration plates 6-1 are set in parallel, and the distance between the two calibration plates 6-1 is adapted to the width of the carbon fiber cloth, for resting against the bridge bottom plate.

[0034] There are two limiting plates 1, which are located on the front side of the two calibration plates 6-1 respectively, and the limiting plates 1 are connected to the calibration plates 6-1. The distance between the two limiting plates 1 is adapted to the width of the carbon fiber cloth.

[0035] The support roller 2 is positioned between the two limiting plates 1 to support the unattached carbon fiber cloth, and the top height of the support roller 2 is less than the top height of the calibration plate 6-1.

[0036] Before use, first overlap the carbon fiber cloth on the support roller 2. By visual inspection, ensure that the attached carbon fiber cloth is positioned between the two calibration plates 6-1 to complete the calibration of the support roller 2. Then, attach the limiting plate 1 close to the bridge bottom plate to guide the unattached carbon fiber cloth and keep it straight with the attached carbon fiber cloth.

[0037] The bridge deck reinforcement using a carbon fiber cloth laying guide device also includes:

[0038] The connecting plate 3, which corresponds one-to-one with the limiting plate 1, connects the limiting plate 1 and the calibration plate 6-1 on the same side. When the limiting plate contacts the bridge bottom plate, the connecting plate 3 is parallel to the bridge bottom plate.

[0039] The pressing roller 4 is positioned between the two connecting plates 3. The pressing roller 4 and the connecting plate 3 slide together along the length of the connecting plate 3. The top of the pressing roller 4 can press the carbon fiber cloth against the bridge bottom plate. The carbon fiber cloth is bonded by sliding along the length of the connecting plate 3.

[0040] In a relatively specific embodiment where the pressing roller 4 and the connecting plate 3 slide together, the pressing roller 4 is rotatably mounted on the wheel frame 5. The two ends of the wheel frame 5 are fixedly mounted with sliding rods 5-1. The opposite surfaces of the two connecting plates 3 are provided with first sliding grooves 3-1. The sliding rods 5-1 are slidably mounted in the first sliding grooves 3-1. When the top of the limiting plate 1 contacts the bridge bottom plate, the first sliding groove 3-1 is parallel to the bridge bottom plate. At this time, the sliding rods 5-1 of the wheel frame 5 are pulled to slide in the first sliding grooves 3-1, and the pressing roller 4 can move in a state parallel to the bridge bottom plate, so as to attach the carbon fiber cloth that has been guided but not pasted to the bridge bottom plate.

[0041] The bridge deck reinforcement using a carbon fiber cloth laying guide device also includes:

[0042] There are two rotating plates 7, which are located on opposite sides of the two limiting plates 1 and are rotatably connected to the limiting plates 1.

[0043] The pressing head 8 is positioned between the two rotating plates 7. The pressing head 8 slides with the rotating plates 7 in the length direction of the rotating plates 7 and is used to cooperate with the support roller 2 to clamp the unattached carbon fiber cloth.

[0044] When the pressing head 8 slides to the state of clamping the carbon fiber cloth, the rotating plate 7 can swing downward to straighten the unattached carbon fiber cloth.

[0045] In a relatively specific embodiment of the limiting plate 1, the limiting plate 1 is circular, and the rotation center of the rotating plate 7 is consistent with the center of the limiting plate 1. When the limiting plate 1 contacts the bridge bottom plate, the pressing head 8 can move along the circumferential direction of the support roller 2 to straighten the carbon fiber cloth.

[0046] In a relatively specific embodiment of the pressing head 8 clamping and then swinging, an arc-shaped groove 1-1 is provided on the opposite sides of the two limiting plates 1. The center of the arc-shaped groove 1-1 is consistent with the center of the limiting plate 1. A straight groove 1-2 is connected to the upward end of the arc-shaped groove 1-1. The orientation of the straight groove 1-2 is parallel to the radial direction of the support roller 2. The width of the arc-shaped groove 1-1 is greater than the width of the straight groove 1-2. Guide rods 8-1 are fixedly installed at both ends of the pressing head 8. The bottom end of the guide rod 8-1 can slide in the arc-shaped groove 1-1 and the straight groove 1-2. A second sliding groove 7-1 is provided on the rotating plate 7. The top end of the guide rod 8-1 is slidably installed in the second sliding groove 7-1, and the top end of the guide rod 8-1 passes through the second sliding groove 7-1. An elastic telescopic rod 9 is rotatably installed on the opposite sides of the two limiting plates 1. The top end of the elastic telescopic rod 9 is rotatably engaged with the top end of the guide rod 8-1. The elastic telescopic rod 9 is in an extended state when no force is applied.

[0047] During use, the elastic telescopic rod 9 is not under force, but an upward elastic force is applied to the top of the guide rod 8-1. At this time, the guide rod 8-1 can be supported at the end of the straight groove 1-2. When the limiting plate 1 approaches the bridge bottom plate, the pressing head 8 contacts the bridge bottom surface. At this time, the guide rod 8-1 is restricted by the straight groove 1-2. The limiting plate 1 continues to move upward, and the guide rod 8-1 slides along the direction of the straight groove 1-2, cooperating with the support roller 2 to clamp the carbon fiber cloth outside the support roller 2 and compress the elastic telescopic rod 9. At this time, the limiting plate 1 continues to move upward. The pressing head 8 swings downward, and the guide rod 8-1 slides along the arc groove 1-1, which will cause the part of the carbon fiber cloth being clamped to move downward along the circumference of the support roller 2. At this time, the connection between the unattached part and the attached part of the carbon fiber cloth is pressed against the bridge base plate by the pressing roller 4, straightening the unattached carbon fiber cloth in a downward inclined state, which makes it easier for the pressing roller 4 to attach the unattached carbon fiber cloth in the future, thus improving the bonding effect. At the same time, as the pressing roller 4 moves, it can straighten the taut carbon fiber cloth even more, further improving the bonding effect.

[0048] The bridge deck reinforcement using a carbon fiber cloth laying guide device also includes:

[0049] The base 10 is clamped and mounted on the top of the basket;

[0050] The bracket 6 is set at the top of the base 10. The bracket 6 slides with the base 10 along the length of the base 10. The top of the bracket 6 is fixedly connected to the calibration plate 6-1 to align the calibration plate 6-1 with the carbon fiber cloth.

[0051] In a relatively specific embodiment of the base 10, clamping plates are slidably provided on both sides of the bottom end of the base 10, and the clamping plates are moved by bolts;

[0052] In a relatively specific embodiment of the bracket 6, the bottom end of the bracket 6 is provided with a sliding plate that slides on the top of the base 10. By adjusting the position of the sliding plate on the base 10, the position of the calibration plate 6-1 is controlled so that the calibration plate 6-1 is kept parallel to the carbon fiber cloth that has been pasted, thereby realizing the guiding function of the carbon fiber cloth.

[0053] In a relatively specific embodiment where the connecting plate 3 is connected to the bracket 6, the top end of the connecting plate 3 is rotatably connected to the bracket 6, and the end of the connecting plate 3 near the limiting plate 1 swings upward to make the limiting plate 1 contact the bridge bottom plate.

[0054] The bridge deck reinforcement using a carbon fiber cloth laying guide device also includes:

[0055] Two locking rods 11 are provided on both sides of the bracket 6. The locking rods 11 are parallel to the bracket 6. The locking rods 11 slide with the bracket 6 in the length direction. The top of the locking rods 11 slides with the end of the connecting plate 3.

[0056] A limiting block 12 is provided at the bottom of the locking rod 11, corresponding to the locking rod 11. The limiting block 12 can prevent the rod 11 from moving in the length direction. The bottom end of the limiting block 12 can contact the base 10 to lock the bracket 6 and the base 10 in the lateral direction.

[0057] In a relatively specific embodiment where the limiting block 12 achieves the locking effect, a spring is provided between the limiting block 12 and the locking rod 11 to provide elastic movement space when the locking rod 11 drives the limiting block 12 to move downward, so that the limiting block 12 can be in close contact with the top of the base plate. The bottom end of the limiting block 12 is made of rubber to increase the friction between the limiting block 12 and the base plate. The end of the connecting plate 3 is provided with a through groove 3-2, and the top end of the locking rod 11 is slidably disposed in the through groove 3-2. When one end of the connecting plate 3 near the limiting block 12 swings upward, the other end of the connecting plate 3 swings downward and drives the locking rod 11 to press downward, so that the limiting block 12 can be tightly fitted with the base 10, so that the position of the bracket 6 and the base 10 remains unchanged when the connecting plate 3 is parallel to the bridge base plate, keeping the pressing roller 4 stable during sliding, which facilitates the pasting of the unpainted carbon fiber cloth.

[0058] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
