Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention. Embodiment 1

[0033] Please refer to Figure 1 - Figure 5 , an adjustable-frequency concrete vibrating table, comprising: a mounting frame 1, two hydraulic cylinders 2 are installed through the mounting frame 1, the bottoms of the two hydraulic cylinders 2 are fixedly connected to an I-shaped plate 3, the bottom of the I-shaped plate 3 is fixedly installed with a connecting frame 4, both sides of the connecting frame 4 are provided with a plurality of square plates, and a high-frequency vibrating rod 5 is fixedly installed on each of the plurality of square plates;

[0034] A vibrating table group 8, the vibrating table group 8 is arranged inside the mounting frame 1;

[0035] A vibrating assembly 9, the vibrating assembly 9 is arranged on the vibrating table group 8.

[0036] For the adjustable-frequency concrete vibrating table provided by the present invention, during use, the vibrating table group 8 is started through the controller self-equipped on the device, so as to be able to vibrate the concrete member on the vibrating table group 8. At the same time, the controller controls the hydraulic cylinder 2 to drive the I-shaped plate 3 and the connecting frame 4 to descend, so that the high-frequency vibrating rod 5 can quickly insert into the concrete member, and then the controller controls the high-frequency vibrating rod 5 to start, so that the high-frequency vibrating rod 5 can vibrate the upper part of the concrete member. During the vibration, the contracted hydraulic cylinder 2 drives the I-shaped plate 3, the connecting frame 4 and the high-frequency vibrating rod 5 to slowly rise, so as to be able to discharge the air bubbles in the member, thereby ensuring the internal strength quality and the appearance smoothness of the member. Finally, through the vibrating assembly 9, the vibration frequency of the vibrating table group 8 can be adjusted according to the demand situation.

[0037] Further, the vibration table group 8 includes a fixed seat 81 arranged inside the mounting frame 1. Four first mounting shells 82 are fixedly installed on the top of the fixed seat 81. A spring 85 is fixedly installed on the inner bottom wall of the fixed seat 81. A placement table 83 is arranged above the fixed seat 81. Four second mounting shells 84 are fixedly installed on the bottom of the placement table 83, and the first mounting shells 82 and the second mounting shells 84 are arranged opposite to each other vertically. The top of the spring 85 is fixedly connected to the inner top wall of the second mounting shell 84. A first vibration motor 86 is fixedly installed on the bottom of the placement table 83 through a first fixing frame.

[0038] Specifically, by starting the first vibration motor 86 through the controller, then the first vibration motor 86 drives the placement table 83 to vibrate with the cooperation of the spring 85, so as to remove the air bubbles inside the concrete member, and then the setting property of the concrete can be increased. At the same time, the spring 85 can also damp the vibration force feedback from the placement table 83 to the fixed seat 81 during vibration, avoiding the displacement of the fixed seat 81 under the action of the vibration force.

[0039] Further, the vibration assembly 9 includes four second fixing frames 91 fixedly installed on the bottom of the placement table 83, and the four second fixing frames 91 are arranged in a cross shape.

[0041] Further, a plurality of limiting rods 10 are fixedly installed on the bottom of the placement table 83. A plurality of round holes are formed in the fixed seat 81, and the bottom of the limiting rods 10 is inserted into the round holes.

[0042] Specifically, through the cooperation of the limiting rods 10 with the fixed seat 81 and the round holes thereon, the placement table 83 can be limited, and then the stability performance of the placement table 83 can be ensured, avoiding the phenomenon of skew displacement of the placement table 83 under the action of the spring 85, and further avoiding affecting the use of the spring 85.

[0043] Further, four fixing blocks 11 are fixedly installed on the bottom of the fixed seat 81, and rubber pads 12 are fixedly installed on the bottoms of the four fixing blocks 11.

[0044] Specifically, through the rubber pads 12 at the bottoms of the fixing blocks 11, the damage to the ground or the vibration table group 8 caused by the fixed seat 81 colliding with the ground during vibration can be reduced, and at the same time, the noise caused by the collision can be avoided.
