Technical Field

[0001] This utility model relates to the field of bridge maintenance technology, specifically to a bridge repair crack repair device. Background Technology

[0002] A bridge is a structure built over canyons, valleys, roads, railways, rivers, other bodies of water, or other obstacles to connect roads at both ends, allowing people, vehicles, trains, or ships to cross the obstacle. Over long-term use, bridges are prone to developing cracks in their decks and structures due to load, environmental factors, and material aging. If these cracks are not repaired promptly, they will gradually widen, affecting the structural safety and lifespan of the bridge.

[0003] Currently, when using crack repair devices, there is a lack of synchronous pretreatment mechanisms. Usually, to ensure the filling and repair effect of cracks, pretreatment of crack widening is required. After widening, tools such as wire brushes and high-pressure water guns are needed to clean the crack surface. The continuity of pretreatment operations is poor, and manual operation is laborious and inefficient. Therefore, a bridge repair crack repair device is proposed to add a synchronous pretreatment mechanism. By simultaneously widening and cleaning the pretreatment, the ease of use of the device can be improved, and the repair quality and effect of bridge cracks can be improved, thereby enhancing the overall performance.

[0019] To improve the effectiveness of crack repair, for example, such as Figure 1 , Figure 4 As shown, the present invention also includes the smoothing component 5, which includes an L-shaped frame 501. A hollow groove 502 is provided at the bottom of the L-shaped frame 501. A heat-conducting plate 503 is bolted into the hollow groove 502. A heating tube 504 is bolted to the bottom of the heat-conducting plate 503 in the hollow groove 502.

[0020] Dust cover 3 is a transparent dust cover.

[0021] The bottom of the fixing bracket 202 is provided with an O-ring seal around the sleeve 205.

[0022] The bristles are made of steel wire.

[0023] During use, an auxiliary smoothing mechanism is added through the L-shaped frame 501, hollow groove 502, heat-conducting plate 503 and heating pipe 504. The sliding displacement method is used to help remove excess mud overflowing from the crack surface and improve the aesthetics of crack repair.

[0024] For example, such as Figure 3 As shown, the present invention also includes a reaming drill bit 208 at the bottom of the support frame 201, and the reaming drill bit 208 passes through the fixing frame 202, the worm gear 203 and the bristles 207 through a reserved opening. A drive motor 209 is bolted inside the support frame 201, and the drive motor 209 is connected to the reaming drill bit 208 through a drive shaft.

[0025] In use, the bridge cracks can be pre-expanded by the drive motor 209 and the expansion drill bit 208. The support frame 201 includes a second drive motor, which is connected to the worm gear 204 via a drive shaft.

[0026] For example, such as Figure 5 As shown, this utility model also includes the following: the guide assembly 4 includes a lifting frame 401, a ball screw 402 is installed in the lifting frame 401 through a bearing, a corresponding nut seat 403 is sleeved around the ball screw 402, and the nut seat 403 is bolted to an L-shaped frame 501; a servo motor 404 is bolted to one side of the lifting frame 401, and the servo motor 404 is connected to the ball screw 402 through a drive shaft; the trolley 1 includes a cylinder 6, and the output end of the cylinder 6 is bolted to the lifting frame 401.

[0027] In use, the lifting frame 401, ball screw 402, nut seat 403, servo motor 404 and cylinder 6 can control and adjust the position and range of the smoothing component 5 after the grouting repair is completed. The ball screw 402 includes a telescopic protective cover.

[0028] For example, such as Figure 2 As shown, the present invention also includes a flow guide groove 301 inside the dust cover 3, a dust collection box 302 connected to one side of the dust cover 3 by bolts, and the dust collection box 302 is connected to the flow guide groove 301. A vacuum pump 303 is connected to one side of the dust collection box 302 by bolts, and the air inlet of the vacuum pump 303 is connected to the dust collection box 302 through a pipe.

[0029] During use, the guide channel 301, dust collection box 302, and vacuum pump 303 can utilize the negative pressure generated by suction to assist in the recovery of waste and dust generated during the pretreatment process, improving the quality of the working environment and reducing the residue of impurities in cracks. The dust collection box 302 is equipped with a removable filter.

[0030] For example, such as Figure 1 , 2 As shown, the present invention also includes a material bucket 7 bolted to the top of the trolley 1, an electric push rod 102 bolted to the top of the mounting frame 101, and the output end of the electric push rod 102 bolted to the support frame 201. The mounting frame 101 includes a connecting seat 103.

[0031] In use, the material bucket 7 facilitates the grouting and filling repair of bridge cracks. The material bucket 7 includes a grouting pump and a grouting nozzle.

[0032] When using this utility model, the operator first pushes the trolley 1 to the bridge crack, turns on the electric push rod 102 to drive the support frame 201 to slide downward, and drives the crack widening drill bit 208 to widen the crack through the drive motor 209. At the same time, the second drive motor drives the worm gear 204 to rotate, and the worm wheel 203 drives the sleeve 205 and brush plate 206 to rotate, so that the brush bristles 207 can perform crack cleaning action simultaneously. The vacuum pump 303 uses the negative pressure generated by suction to suck the waste and dust generated during the pretreatment process into the dust collection box 302 through the guide channel 301 to complete the synchronous auxiliary cleaning and recycling. The operation is simple and convenient, and it greatly improves the speed and efficiency of pretreatment before crack repair, and also helps to shorten the crack repair time. After the crack pretreatment is completed, the slurry in the material bucket 7 is injected into the bridge crack through the grouting pump and grouting nozzle for filling and repair. After the filling and repair are completed, the lifting frame 401 is driven to slide down by the cylinder 6, so that the L-shaped frame 501 contacts the crack surface. At the same time, the servo motor 404 drives the ball screw 402 to rotate, and the nut seat 403 drives the L-shaped frame 501 to move back and forth horizontally, which can remove excess slurry overflowing from the crack surface, so as to improve the aesthetics of the crack repair. The heating pipe 504 can also be turned on, and the repair area is heated through the heat conduction plate 503 to assist in the drying effect, further improving the speed and efficiency of crack repair, and making it more flexible and reliable.
