[0019] The following will describe in detail the specific implementation of the present utility model in conjunction with specific embodiments.

[0020] As Figure 1 , Figure 2 , Figure 3 shown, a structural diagram of a precast bridge deck roughening device provided by an embodiment of the present utility model includes a fixed frame 1. The fixed frame 1 has an inverted U-shaped structure. A carrier frame 3 is slidably installed in the inner cavity of the fixed frame 1 along the horizontal plane direction. The carrier frame 3 has an inverted U-shaped structure. A transverse plate 4 is arranged in the inner cavity of the carrier frame 3. A plurality of groups of evenly distributed roughening cones 41 are arranged on the bottom wall of the transverse plate 4. A bridge deck body 2 is placed below the fixed frame 1. A translation assembly 5 that cooperates with the carrier frame 3 is arranged on the side wall of the fixed frame 1. A cleaning assembly 7 that cooperates with the roughening cones 41 is arranged on the side wall of the fixed frame 1. A roughening mechanism 6 that cooperates with the transverse plate 4 is arranged on the surface of the carrier frame 3. The roughening mechanism 6 includes a positioning assembly 61 and a telescopic assembly 62. The positioning assembly 61 is located on the side wall of the carrier frame 3 and is connected to both ends of the transverse plate 4. The telescopic assembly 62 is located between the two side walls of the carrier frame 3.

[0021] During use, the bridge deck body 2 to be roughened is placed below the inner cavity of the fixed frame 1. The translation assembly 5 controls the carrier frame 3 to slide horizontally above the bridge deck body 2. While the carrier frame 3 drives the transverse plate 4 and the roughening cones 41 to move, the telescopic assembly 62 and the positioning assembly 61 cooperate with each other to control the transverse plate 4 to reciprocate vertically. The transverse plate 4 drives the roughening cones 41 to move downward synchronously. The roughening cones 41 can perform all-round roughening processing on the surface of the bridge deck body 2. After moving unidirectionally to one side of the fixed frame 1, the cleaning assembly 7 can perform all-round automatic cleaning on the impurities attached to the surface of the roughening cones 41, effectively improving the continuous roughening effect of the roughening cones 41.

[0022] As Figure 1 , Figure 2 , Figure 3As shown, as a preferred embodiment of the present utility model, the translation assembly 5 includes a threaded rod 51 rotatably installed on opposite side walls of the fixed frame 1. The threaded rod 51 is helically connected to the carrier 3. A first motor 52 is fixedly installed on the side wall of the fixed frame 1, and the output shaft of the first motor 52 is connected to the threaded rod 51.

[0023] During use, the first motor 52 drives the threaded rod 51 to rotate, and the threaded rod 51 pushes the carrier 3 to reciprocate in the inner cavity of the fixed frame 1.

[0024] As Figure 1 、 Figure 2 、 Figure 3 As shown, as a preferred embodiment of the present utility model, the positioning assembly 61 includes vertical slots 611 respectively opened on opposite side walls of the carrier 3. A sliding block 612 is slidably installed in the vertical slot 611. The sliding blocks 612 are respectively connected to both ends of the cross plate 4. A compression spring 613 connected to the sliding block 612 is fixedly installed on the bottom wall of the vertical slot 611.

[0025] During use, multiple groups of sliding blocks 612 support and position the cross plate 4. The movement of the sliding blocks 612 in the vertical slots 611 can drive the cross plate 4 to reciprocate in the vertical direction. The telescopic assembly 62 pushes the cross plate 4 downward. After the cross plate 4 moves to the lowest position, the compression spring 613 pushes the sliding block 612 to move upward in the vertical slot 611, and the sliding block 612 drives the cross plate 4 to move upward synchronously.

[0026] As Figure 1 、 Figure 2 、 Figure 3 As shown, as a preferred embodiment of the present utility model, the telescopic assembly 62 includes a transmission column 621 rotatably installed between opposite side walls of the carrier 3 and located above the cross plate 4. A cam 622 cooperating with the cross plate 4 is fixedly installed on the surface of the transmission column 621. One end of the transmission column 621 extends outside the side wall of the carrier 3 and is connected to a second motor 623.

[0027] During use, the second motor 623 drives the transmission column 621 to rotate. The transmission column 621 drives the cam 622 to rotate above the cross plate 4. The cam 622 squeezes the cross plate 4 during rotation, thereby pushing the cross plate 4 to move downward in the vertical direction.

[0028] As Figure 1 、 Figure 2 、 Figure 3As shown, as a preferred embodiment of the present utility model, the cleaning assembly 7 includes two sets of laterally distributed side plates 71 fixedly installed on the side wall of the fixed frame 1. A cleaning rod 72 is rotatably installed between the two sets of side plates 71. Multiple groups of uniformly distributed brushes 73 are arranged on the surface of the cleaning rod 72. A fixed gear disk 74 is fixedly installed on the surface of the cleaning rod 72. A rack 75 meshing with the fixed gear disk 74 is fixedly installed on the bottom wall of the carrier 3 through a bracket.

[0029] During use, when the carrier 3 moves towards the side wall of the fixed frame 1, the rack 75 meshes with and drives the fixed gear disk 74 to rotate. The fixed gear disk 74 drives the cleaning rod 72 and the brushes 73 to rotate synchronously, and the brushes 73 can automatically clean the chiseling cone 41.

[0030] The working principle of the present utility model is as follows: During use, the bridge deck body 2 to be chiseled is placed below the inner cavity of the fixed frame 1. The first motor 52 drives the threaded rod 51 to rotate, and the threaded rod 51 pushes the carrier 3 to reciprocate in the inner cavity of the fixed frame 1. The carrier 3 drives the cross plate 4 and the chiseling cone 41 to move. The second motor 623 drives the transmission column 621 to rotate, and the transmission column 621 drives the cam 622 to rotate above the cross plate 4. When the cam 622 rotates, it squeezes the cross plate 4, thereby pushing the cross plate 4 to move downward in the vertical direction. After the cross plate 4 moves to the lowest position, the compression spring 613 pushes the sliding block 612 to move upward in the vertical groove 611, and the sliding block 612 drives the cross plate 4 to move upward synchronously.

[0031] The cross plate 4 drives the chiseling cone 41 to move downward synchronously. The chiseling cone 41 can perform all-round chiseling processing on the surface of the bridge deck body 2. After moving unidirectionally to one side of the fixed frame 1, the rack 75 meshes with and drives the fixed gear disk 74 to rotate. The fixed gear disk 74 drives the cleaning rod 72 and the brushes 73 to rotate synchronously, and the brushes 73 can automatically clean the chiseling cone 41.

[0032] The above has described the preferred embodiments of this patent in detail, but this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the purpose of this patent.
