Description

Technical Field

[0001] This utility model relates to the technical field of bridge reinforcement, specifically a carbon fiber plate reinforcement device for railway steel plate girder bridges. Background Technology

[0002] The carbon fiber plate reinforcement device for railway steel plate girder bridges is a new technology that uses high-strength carbon fiber reinforced polymer (CFRP) composite material to reinforce existing steel beams. It improves the bending resistance, fatigue resistance and corrosion resistance of bridges through bonding or mechanical anchoring. It is suitable for the rapid reinforcement of existing lines without interrupting train operation.

[0003] Existing carbon fiber plate reinforcement devices for railway steel plate girder bridges typically require workers to lift and bond the carbon fiber plates to the bridge for reinforcement. This is labor-intensive and requires force during bonding. Relying solely on manual pressing is time-consuming and laborious, resulting in poor bonding effects, affecting the stability of the reinforcement, and ultimately leading to unsatisfactory performance.

[0004] Therefore, we propose a carbon fiber plate reinforcement device for railway steel plate girder bridges to solve the problems mentioned above. Utility Model Content

[0019] Example 1 Please see Figure 1-7 A carbon fiber plate reinforcement device for railway steel plate girder bridge includes a lifting body 1 and a carrier 2 installed at the upper end of the lifting body 1. A fixed platform 3 is provided on the top of the carrier 2 near the right side, and a servo motor A4 is provided at the middle of the bottom of the fixed platform 3.

[0020] The adsorption assembly 8 includes a fixed plate 81 fixedly installed at the bottom of the cavity near the left front side and a drive motor 82 fixedly installed at the front side of the fixed plate 81 near the left side. A turntable is fixedly installed at the output end of the drive motor 82, and a fixed shaft 83 is fixedly installed at the front edge of the turntable. A sliding frame 84 is slidably sleeved on the outer side of the fixed shaft 83. A fixed rod 85 is fixedly installed in the middle of the right side of the sliding frame 84, and a movable plate 86 is fixedly installed at the right end of the fixed rod 85. The rear side of the movable plate 86 is slidably installed on the fixed plate 81. A T-shaped plug plate 87 is fixedly installed on the right side of the movable plate 86 near the front side. A plug cylinder 88 is slidably sleeved on the outer side of plate 87, and an air extraction pipe is fixedly installed through the rear side of the plug cylinder 88 near the right end. A suction pipe 89 is provided on the right side of the rear side of the plug cylinder 88, and the rear end of the air extraction pipe is fixedly extended through into the inner cavity of the suction pipe 89. A one-way valve A is provided on the outer side of the air extraction pipe, and a connecting pipe is fixedly installed through the front side of the suction pipe 89 near the right side. A solenoid valve is provided on the outer side of the connecting pipe. A connecting pipe is fixedly installed through the front side of the plug cylinder 88 near the right side, and a one-way valve B is provided on the outer side of the connecting pipe. This allows the carbon fiber plate placed on the placement seat 5 to be adsorbed and fixed, improving the stability during bonding.

[0021] An arc-shaped mounting block 881 is fixedly installed on the rear side of the plug cylinder 88 near the left side, and the rear side of the arc-shaped mounting block 881 is fixedly installed on the fixing plate 81, which serves to support and fix the plug cylinder 88.

[0022] Limiting plates 841 are fixedly installed at the middle of the top and bottom of the sliding frame 84, and limiting rods 842 are slidably installed through the limiting plates 841. A straight plate 843 is fixedly installed on the left end of the limiting rods 842. The rear side of the straight plate 843 is fixedly installed on the fixed plate 81, which serves to guide and limit the movement of the sliding frame 84, so that it can move back and forth stably.

[0023] Adsorption tubes 891 are fixedly installed through the top of the suction tube 89 near its four sides, and the upper ends of the adsorption tubes 891 are fixedly extended through the outer side of the placement seat 5. Support blocks 892 are fixedly installed above the left and right sides of the suction tube 89. The tops of the support blocks 892 are fixedly installed on the inner wall of the cavity, which is conducive to generating adsorption force on the carbon fiber plate and also serves to support and fix the suction tube 89.

[0025] A support frame 41 is fixedly installed at the middle of the bottom of the servo motor A4, and the upper end of the support frame 41 is fixedly installed on the fixed platform 3, which can fix the servo motor A4 and prevent it from being suspended in the air.

[0026] In this embodiment: During use, the carbon fiber plate can be placed on the placement seat 5, positioned between baffles A6 and B7. After placement, the drive motor 82 can be started. When the drive motor 82 is running, it will drive the turntable to rotate. When the turntable rotates, it will drive the sliding frame 84 to move back and forth left and right through the fixed shaft 83. When the sliding frame 84 moves to the left, it will drive the moving plate 86 to move to the left through the fixed rod 85. At this time, the T-shaped stopper plate 87 will also move to the left inside the stopper cylinder 88, which will draw air from the suction pipe 89 through the suction pipe. When the sliding frame 84 moves to the right, it will discharge the drawn air through the connecting pipe, thereby adsorbing and fixing the placed carbon fiber plate, improving its stability during bonding and preventing it from shifting. To release, simply open the solenoid valve to allow air to enter the suction pipe 89, thereby eliminating the adsorption force and separating the carbon fiber plate from the placement seat 5, thus completing the bonding and reinforcement work.

[0027] Example 2 This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figure 1-2 , Figure 4-5 and Figure 7 The adjustment component 9 includes a servo motor B91 located at the middle of the left side of the placement seat 5. The output end of the servo motor B91 extends movably through into the inner cavity of the rectangular groove on the left side and is fixedly mounted with a driving bevel gear 92. A driven bevel gear 93 meshes with the rear side of the driving bevel gear 92, and a movable rod is fixedly mounted through the middle of the driven bevel gear 93. Threaded rods 94 are fixedly mounted at both ends of the movable rod. The external threads of the threaded rods 94 are arranged in opposite directions. Threaded sleeves 95 are threadedly mounted on the outer side of the threaded rods 94 near the middle. A shaped connecting rod 96 is fixedly mounted at the middle of the top of each threaded sleeve 95. The end of the shaped connecting rod 96 away from the adjacent threaded sleeve 95 extends to the outer side of the placement seat 5 and is fixedly mounted on adjacent baffles B7. The distance between the front and rear baffles B7 can be adjusted, thus forming a placement frame with the baffles A6, which is beneficial for placing the carbon fiber plate.

[0028] The threaded rod 94 and threaded sleeve 95 involved in this application are manufactured with the same precision, which can meet the requirement of driving the front and rear side baffles B7 to move relative to each other or in opposite directions. Moreover, it is a mature prior art, so this application will not elaborate on it further.

[0029] A support plate 911 is fixedly installed at the middle of the top of the servo motor B91, and the right side of the support plate 911 is fixedly installed on the placement seat 5, which serves to support and fix the servo motor B91.

[0030] Guide plates 951 are fixedly installed at the bottom of each threaded sleeve 95, and guide rods 952 are slidably installed through each guide plate 951. Side plates 953 are movably installed at the opposite end of each guide rod 952. The bottom of each side plate 953 is fixedly installed on the bottom wall of the inner cavity of the left rectangular groove, and the opposite end of each threaded rod 94 is movably installed on the adjacent side plates 953, which serves to guide and limit the movement of the threaded sleeve 95, and also to support the rotation of the threaded rod 94.

[0031] In this embodiment: when the carbon fiber plate is placed on the placement seat, the front and rear baffles B7 can be adjusted to fit the carbon fiber plate. The operation of the servo motors B91 on both sides will drive the adjacent active bevel gears 92 to rotate. When the active bevel gears 92 rotate, they will drive the driven bevel gears 93 to rotate. When the driven bevel gears 93 rotate, they will drive the threaded rods 94 on the front and rear sides to rotate through the interactive rods. When the threaded rods 94 rotate, they will drive the adjacent threaded sleeves 95 to move relative to each other. When the threaded sleeves 95 move relative to each other, they will drive the front and rear baffles B7 to move relative to each other through the adjacent irregular connecting rods 96. Thus, they can form a placement frame with the baffles A6 for placing the carbon fiber plate, which makes the bonding more stable.
