[0018] like Figures 1 to 4 As shown, a bridge deck secondary reinforcement crack repair construction device includes a handcart 1, a brush wheel 3, a dust cover 5, a suction pump 6, and a dust removal component 7. A handrail 2 is provided at the rear end of the handcart 1, which is used for moving on the ground. The brush wheel 3 is rotatably mounted at the front end of the handcart 1; the brush wheel can be a wire brush. A power component 4 is mounted on the handcart 1, and the power component 4 drives the brush wheel 3 to rotate.

[0019] In a relatively specific embodiment, the handcart 1 includes a frame 101 and wheels 102. One wheel 102 is rotatably mounted at each of the front and rear ends of both sides of the frame 101, and the two wheels 102 at the front end are coaxial with the brush wheel 3. During the cleaning process, the worker holds the handle 2 and can push the handcart 1 back and forth.

[0020] Optionally, the front end of the handrail 2 is rotatably mounted on the handcart 1, allowing the rear end of the handrail 2 to swing in the vertical plane. A positioning component is provided between the handrail 2 and the handcart 1 to fix the tilt angle of the handrail 2. This configuration allows for adjustment of the tilt angle of the handrail 2 to better meet construction needs and improve worker comfort.

[0021] Optionally, the positioning assembly includes a pin hole 8, a positioning hole 9, and a positioning pin 10. The pin hole 8 is located on the handcart 1, and the positioning holes 9 are equidistant from the rotation center of the handrail 2 on the handrail 2. The positioning pin 10 passes through one of the positioning holes 9 and then through the pin hole 8. After the positioning pin 10 is pulled out of the pin hole 8, the handrail 2 can be swung to adjust its tilt angle. Then, the positioning pin 10 is passed back through the pin hole 8 to fix the tilt angle of the handrail 2.

[0022] In a relatively specific embodiment, a crossbar 17 is fixedly installed on the handcart 1, and a rod sleeve 18 is fixedly installed at the front end of the handle 2. The rod sleeve 18 is rotatably sleeved on the middle of the crossbar 17. A pin hole 8 is provided on the crossbar 17, and a positioning hole 9 is provided on the rod sleeve 18.

[0023] Optionally, the power assembly 4 includes a motor 401 and a pulley mechanism 402. The motor 401 is mounted on the trolley 1, and the pulley mechanism 402 connects the motor 401 and the brush wheel 3. When the motor 401 is started, it drives the brush wheel 3 to rotate via the pulley mechanism 402, thereby achieving the cleaning effect of the brush wheel 3.

[0024] Specifically, the motor 401 is mounted on the frame 101, and the pulley mechanism 402 includes a belt, a drive wheel and a driven wheel. The drive wheel is mounted on the power shaft of the motor 401, the driven wheel is connected to the brush wheel 3, and the belt is connected between the drive wheel and the driven wheel.

[0025] The dust cover 5 is installed on the handcart 1, and the brush wheel 3 is located inside the dust cover 5. The bottom of the dust cover 5 has an opening, and the bottom of the brush wheel 3 extends out from the opening. In this embodiment, the bottom width of the dust cover 5 is greater than the width of the groove, and a sealing ring 19 is provided on the outer periphery of the bottom of the dust cover 5. The sealing ring 19 is a hollow tubular rubber ring that is tightly attached to the ground, thereby sealing the gap between the outer periphery of the bottom of the dust cover 5 and the ground, which can better reduce dust and secondary pollution.

[0026] The suction pump 6 is installed on the handcart 1. Specifically, the suction pump 6 can be an industrial-grade dry and wet vacuum pump. The suction pump 6 is installed on the frame 101. The suction pump 6 can extract the residue inside the dust cover 5, so that the residue generated during cleaning can be extracted from the tank in real time, thereby improving the cleaning effect.

[0027] The dust removal component 7 is installed on the handcart 1. The suction pump 6 extracts the residue from the dust cover 5 and discharges it into the external environment through the dust removal component 7. The dust removal component 7 is installed on the frame 101. The dust removal component 7 can filter the mixture of residue and gas extracted from the dust cover 5 by the suction pump 6, trapping and collecting the residue, and discharging the filtered gas into the external environment, thereby reducing dust and secondary pollution.

[0028] In this embodiment, a polygonal shaft 11 is slidably mounted at the center of the brush wheel 3. Both ends of the polygonal shaft 11 are rotatably connected to the handcart 1. A storage spring 12 is provided on both sides of the brush wheel 3. When the brush wheel 3 is located in the middle of the polygonal shaft 11, both storage springs 12 are at their free length. During the cleaning process, the brush wheel 3 is squeezed by the inner wall of the groove when passing through the curved part of the groove. The brush wheel 3 can move outside the polygonal shaft 11, and during this movement, it compresses the storage spring 12 located at the front of its moving direction. Simultaneously, the storage spring 12 located at the rear of the brush wheel 3 moves synchronously with the brush wheel 3. This arrangement allows the storage springs 12 on both sides to enable the brush wheel 3 to adapt to the curvature of the groove and maintain a state of contact with the groove wall, thereby improving the cleaning effect.

[0029] Optionally, a sliding sleeve 13 is connected to the end of the energy storage spring 12 away from the brush wheel 3. The sliding sleeve 13 is located outside the polygonal shaft 11. The sliding sleeve 13 can move synchronously with the brush wheel 3, thereby providing stable support to the outer end of the energy storage spring 12. During the rotation of the polygonal shaft 11, the sliding sleeve 13 can rotate synchronously with the polygonal shaft 11, thereby causing both ends of the energy storage spring 12 to rotate synchronously.

[0030] In this embodiment, the drive wheel is mounted on one end of the polygonal shaft 11, so that the drive wheel is connected to the brush wheel 3 through the polygonal shaft 11. When the motor 401 is running, it drives the polygonal shaft 11 to rotate through the pulley mechanism 402, and the polygonal shaft 11 drives the brush wheel 3 to rotate.

[0031] Optionally, the dust cover 5 is rotatably fitted onto both ends of the brush wheel 3 on both sides, so that the dust cover 5 will not rotate with the brush wheel 3 during its rotation. The rear end of the top of the dust cover 5 is slidably mounted on the handcart 1, and a slide rod 20 is slidably passed through the rear end of the top of the dust cover 5. The two ends of the slide rod 20 are fixed to the frame 101, so that the dust cover 5 can move with the brush wheel 3 as the brush wheel 3 moves outside the polygonal shaft 11, thereby reducing dust and secondary dirt and improving the cleaning effect.

[0032] A hose 14 is provided between the suction pump 6 and the dust cover 5. By providing the hose 14, the suction pump 6 can keep removing the residue inside the dust cover 5 in real time as the dust cover 5 moves axially along the polygonal axis 11 along with the brush wheel 3.

[0033] Optionally, the dust removal assembly 7 includes a cylinder 701, a filter element 702, and a spiral plate 703. The cylinder 701 is fixedly mounted on the handcart 1. The exhaust pipe 15 of the suction pump 6 is connected to the inner end of the cylinder 701. The filter element 702 is installed inside the cylinder 701. The spiral plate 703 is disposed between the outer surface of the filter element 702 and the inner wall of the cylinder 701. An external discharge channel 704 is provided at the center of the filter element 702 and at the center of the outer end of the cylinder 701.

[0034] A detachable cover 705 is provided at the outer end of the cylinder 701. An external discharge channel 704 is located at the center of the cover 705 at the outer end of the cylinder 701. The outer end of the filter element 702 is fixedly installed on the cover 705. The spiral plate 703 abuts against the outer surface of the filter element 702 and the inner wall of the cylinder 701.

[0035] The residue inside the dust cover 5 is drawn into the cylinder 701 by the suction pump 6. The residue can pass through various parts of the filter element 702 along the direction of the spiral plate 703. The residue is intercepted, while the gas enters the outer discharge channel 704 of the filter element 702 from the outer surface of the filter element 702 and is discharged into the external environment through the outer discharge channel 704 of the cylinder cover 705.

[0036] In a relatively specific embodiment, the filter element 702 includes a frame and a filter screen, with the filter screen embedded in the frame and the outer end of the frame fixedly connected to the cylinder cover 705.

[0037] Optionally, the front end of the filter element 702 is provided with a cone head 16, the tip of which extends into the outer end of the exhaust pipe 15, and there is a gap between the side surface of the cone head 16 and the outer end of the exhaust pipe 15. The cone head 16 is fixed to the front end of the frame, and guides the residue entering the cylinder 701, making it easier for the residue to enter the area where the spiral plate 703 is located, thereby improving the residue filtration effect.

[0038] 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.
