Referring to fig. 1-3, the present embodiment provides a vibration apparatus, which includes a vibration table 1 and a suspension member (not shown in the drawings), wherein the vibration table 1 includes a table body 11 and a vibration member 12, the suspension member is connected to the table body 11 to suspend the table body 11 in the air, and the vibration member 12 is used for generating vibration to the table body 11. Therefore, under the action of the suspension piece, the table body 11 can rock in the air, so that concrete in the table body 11 can be tightly shaken, and the mold closing production process is completed.

In the present embodiment, the hanger is a wire rope, which can effectively improve the connection strength. In other embodiments, the hanger may also be a nylon rope, steel shaft, or the like.

Specifically, referring to fig. 1 to 3, in the present embodiment, the vibrating element 12 includes a disc 123, a connecting rod 122 and a motor 121, the disc 123 is fixedly installed on the table body 11, an annular abutting portion 13 is formed at an edge of the disc 123, two ends of the connecting rod 122 abut against inner sides of the abutting portion 13, the motor 121 includes a housing 1211 and an output shaft 1212, the output shaft 1212 is rotatably connected to the housing 1211, the housing 1211 is installed on a predetermined object, and one end of the output shaft 1212, which is away from the housing 1211, is connected to the connecting rod 122.

It is understood that when the motor 121 is activated, the output shaft 1212 can drive the connecting rod 122 to rotate around the axis of the output shaft 1212. Since the abutting portion 13 is annular, both ends of the link 122 always abut against the inside of the abutting portion 13 during the rotation.

In the present embodiment, a certain offset (distance indicated by B in fig. 3) is provided between the axis of the output shaft 1212 and the center of the abutting portion 13, so that when the connecting rod 122 rotates around the axis of the output shaft 1212, the connecting rod 122 can drive the table body 11 to rock relative to the predetermined object in the clockwise or counterclockwise direction through the abutting portion 13, thereby realizing the function of shaking the concrete.

In the present embodiment, when the vibration amplitude of the table body 11 needs to be adjusted, the vibration amplitude of the table body 11 can be changed by adjusting the offset amount (distance indicated by B in fig. 3) between the axis of the output shaft 1212 and the center of the abutting portion 13. Specifically, the larger the amount of offset, the larger the amplitude of vibration of the table body 11, and the smaller the amount of offset, the smaller the amplitude of vibration of the table body 11.

That is, in the actual use process, the vibration amplitude can be changed by adjusting the relative position between the center of the circle of the abutting portion 13 and the axis of the output shaft 1212, the adjustment process is simple, and the work efficiency can be effectively improved.

In addition, when the shaking rate of the table body 11 needs to be adjusted, the power of the motor 121 may be changed to adjust the rotation speed of the output shaft 1212, thereby changing the shaking rate of the table body 11. Specifically, the greater the rotation speed of the output shaft 1212, the greater the shaking rate of the table body 11, and the smaller the rotation speed of the output shaft 1212, the slower the shaking rate of the table body 11.

Therefore, in the actual use process, the worker can determine the required amplitude and the shaking rate according to the load on the table body 11, and then, the concrete with different weights can be tightly shaken by adjusting the offset and the power of the motor 121.

It should be noted that, in other embodiments, the abutting portion 13 may also be an ellipse, in which case one end of the link 122 abuts against the inner side of the abutting portion 13, and for convenience of description, an end abutting against the inner side of the abutting portion 13 is named as an abutting end. At this time, the maximum distance from the axis of the output shaft 1212 to the inner wall of the abutting portion 13 is ensured to be greater than or equal to the distance between the abutting end and the output shaft 1212, so that when the connecting rod 122 rotates inside the abutting portion 13, the table body 11 can be driven to shake relative to the preset object through the abutting portion 13.

In other embodiments, when the contact portion 13 is elliptical, the axis of the output shaft 1212 may pass through the center of the ellipse or may be offset from the center of the ellipse due to the characteristics of the ellipse itself. That is, the offset between the axis of the output shaft 1212 and the center of the ellipse may be positive or zero.

It is understood that, in other embodiments, when the abutting portion 13 is elliptical and the vibration amplitude of the table body 11 needs to be adjusted, the distance from the axis of the output shaft 1212 to the abutting end may be directly changed, for example, different portions of the link 122 may be connected to the output shaft 1212, the length of the link 122 itself may also be directly changed, and the adjustment process is simple, and the work efficiency may be effectively improved.

Of course, in other embodiments, the abutting portion 13 may be a ring structure with an outer contour having other shapes. One end of the link 122 may abut against the inner wall of the abutting portion 13, or both ends of the link 122 may abut against the inner wall of the abutting portion 13.

In this embodiment, the preset object is a ground, the housing 1211 of the motor 121 is mounted on the ground below the table 11, and the whole table 11 swings relative to the ground after the motor 121 is started. Of course, in other embodiments, the preset object may be other frames, bases, or other devices separated from the table body 11.

In the present embodiment, the disk 123 is fixedly mounted on the table body 11, the abutting portion 13 is formed on the edge of the disk 123, and the abutting portion 13 having different inner diameters can be obtained by replacing the disks 123 of different specifications, which has a wide application range. It should be noted that the disc 123 and the table body 11 can be relatively fixed by a bolt, a screw, a pin shaft, and other parts, and the installation and the replacement are convenient.

In another embodiment, the abutting portion 13 may be an annular protrusion protruding from the table body 11, and the abutting portion 13 may be integrally formed with the table body 11. In another embodiment, the table 11 may be provided with a circular hole, and the inner wall of the circular hole may form the contact portion 13.

Referring to fig. 1 and fig. 2, in the present embodiment, the vibrating element 12 further includes a roller 124, the two ends of the connecting rod 122 are both provided with the roller 124, and the roller 124 can be in rolling contact with the inner side of the abutting portion 13.

It can be understood that, in the process that the output shaft 1212 drives the connecting rod 122 to rotate, the roller 124 rolls on the inner wall of the abutting portion 13, so as to effectively reduce the friction resistance, so that the rotating process of the connecting rod 122 is smoother, and the shaking process of the table body 11 is smoother.

Referring to fig. 1-3, in the present embodiment, a first mounting hole (not shown) is formed in the table body 11, a second mounting hole 125 is formed in the disc 123, the first mounting hole is communicated with the second mounting hole 125, an output shaft 1212 of the motor 121 sequentially passes through the first mounting hole and the second mounting hole 125, the connecting rod 122 is located inside the disc 123, and the housing 1211 and the connecting rod 122 of the motor 121 are located on two opposite sides of the table body 11, respectively.

Specifically, in the present embodiment, the link 122 and the disc 123 are located on the upper side of the table body 11, and the housing 1211 of the motor 121 is located on the lower side of the table body 11. Like this, the upper surface of stage 11 can play the supporting role to disc 123 and connecting rod 122, and connecting rod 122 is at the pivoted in-process, is difficult to and takes place the condition of alternate segregation between disc 123, can guarantee that stage 11 continuously rocks.

It should be noted that in other embodiments, the connecting rod 122, the disc 123 and the casing 1211 of the motor 121 may be located on the same side of the table body 11. For example, the link 122, the disc 123, and the housing 1211 of the motor 121 may be simultaneously located on the upper side of the table body 11, or may be simultaneously located on the lower side of the table body 11.

The upper side and the lower side are referred to as a placement state when the vibration table 1 is normally used. Specifically, the vibration table 1 shown in fig. 1 is placed in a normal use state of the vibration table 1.

Specifically, in the present embodiment, the first mounting hole and the second mounting hole 125 are both circular holes, and the axis of the first mounting hole coincides with the axis of the second mounting hole 125 to form the reference line 2. That is, in the present embodiment, the first mounting hole is disposed coaxially with the second mounting hole 125, so that the output shaft 1212 passes through the first and second mounting holes 125 in sequence.

In addition, referring to fig. 2 and 3, in the present embodiment, the reference line 2 passes through the center of the disc 123 and the center of the connecting rod 122, and the reference line 2 is disposed parallel to the axis of the output shaft 1212. It is understood that, in the present embodiment, the distance between the reference line 2 and the axis of the output shaft 1212 is the offset. That is, the distance between the center of the connecting rod 122 and the axis of the output shaft 1212 is the offset. Therefore, in the actual installation process, different parts of the connecting rod 122 can be connected with the output shaft 1212 according to actual requirements, so that the offset can be adjusted more quickly, and the working efficiency is improved.

Referring to fig. 1 to 3, in the present embodiment, the length direction of the connecting rod 122 is perpendicular to the axial extension direction of the output shaft 1212 of the motor 121. Therefore, in the process that the output shaft 1212 drives the connecting rod 122 to rotate, the situation that one end of the connecting rod 122 is tilted out of the disc 123 is not easy to occur.
