[0020] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0021] A vibrating device for bridge deck paving comprises two movable carriers 1 with handrails 11, a fixed frame 2 is fixedly installed between the upper surfaces of the two movable carriers 1, a rotating rod 3 is rotatably installed in the fixed frame 2, a plurality of cams 31 are equidistantly sleeved on the outer surface of the rotating rod 3, a driving mechanism 4 is installed between the rotating rod 3 and any one of the movable carriers 1, a plurality of directional rods 5 are equidistantly installed through the upper surface of the fixed frame 2, a movable plate 51 is fixedly installed between the lower surfaces of the plurality of directional rods 5, a plurality of reset springs 6 are fixedly installed between the movable plate 51 and the fixed frame 2, and a large vibrating plate 7 which can move up and down with the movable plate 51 is detachably installed below the lower surface of the movable plate 51.

[0022] When in use, the entire device is placed across the area that needs to be vibrated, so that the large vibrating plate 7 is located above the vibrating area, and then the driving mechanism 4 is started to drive the rotating rod 3 to rotate. When the rotating rod 3 rotates, it can drive multiple cams 31 to rotate. When the cam 31 rotates to contact with the movable plate 51, the cam 31 pushes the movable plate 51 downward, thereby driving the large vibrating plate 7 to move down and contact the bridge deck concrete. When the cam 31 continues to rotate and disengages from the movable plate 51, the movable plate 51 moves up and resets under the action of the reset spring 6, so that the large vibrating plate 7 can be repeatedly moved up and down to perform concrete vibration operations in the area. During vibration, since a large vibrating plate 7 is used, there is no need to move the equipment frequently, and concrete in a large range can be vibrated. Compared with the prior art, the use of the device is more efficient in vibration work and more convenient and labor-saving.

[0023] It should be noted that if Figure 2 As shown, the driving mechanism 4 includes a driving motor 41 fixedly mounted on the upper surface of the movable carrier 1, and the outer surface of the output shaft of the driving motor 41 and the outer surface of the rotating rod 3 are both provided with a sprocket 42, and a transmission chain 43 is installed between the two sprockets 42. After the driving motor 41 is powered on and started, the rotating rod 3 can be driven to rotate by the cooperation of the sprocket 42 and the transmission chain 43.

[0024] In addition, if Figure 3 As shown, a plurality of connecting posts 52 are symmetrically fixedly mounted on the lower surface of the movable plate 51, and mounting holes 521 are formed between two corresponding connecting posts 52 at the front and rear sides. Figure 4 As shown, a plurality of fixing rings 71 are symmetrically fixedly installed on the upper surface of the large vibrating plate 7, the bottom end of the connecting column 52 is inserted into the corresponding fixing ring 71, and a long rod bolt 8 is installed through the two corresponding front and rear fixing rings 71. The long rod bolt 8 passes through the corresponding two connecting columns 52 through the mounting hole 521. The connecting column 52 and the fixing ring 71 are fixed by the long rod bolt 8 to realize the connection between the large vibrating plate 7 and the connecting column 52, so that it is installed below the movable plate 51 and can be moved up and down with the movable plate 51.

[0025] In addition, in order to reduce the noise generated when the cam 31 drives the movable plate 51 to move, Figure 3 As shown, a plurality of rubber pads 53 are fixedly installed at equal intervals on the upper surface of the movable plate 51. When the rubber pads 53 are located directly below the corresponding cams 31, the rubber pads 53 can be used to contact the cams 31, thereby utilizing the unique rubber material of the rubber pads 53 to reduce the generation of noise.

[0026] Specifically, the number of the assembled return springs 6 is the same as the number of the assembled directional rods 5 , and the return springs 6 are sleeved on the outside of the corresponding directional rods 5 .
