Wherein the box body 1 can be an integrally formed glass fiber reinforced plastic box body. The box body adopts a mould pressing integrated forming process, so that the arc smoothness and the flatness of the outer surface of the box body are ensured, the problem that the box body needs to be repaired by using a filling agent due to the fact that the arc of the outer surface of the box body is not smooth and flat is solved, and the coating surface quality is improved.
For example, a first cavity 11, a second cavity 12 and a third cavity are arranged in the box body 1, the first cavity 11 and the second cavity 12 are communicated through a third communicating pipeline, the first cavity 11 and the third cavity are communicated through a fourth connecting pipeline, and the second cavity 12 and the third cavity are communicated through a fifth connecting pipeline. Each connecting pipeline can be a connecting pipeline processed in the box body 1 or a connecting pipeline arranged outside the box body 1, and the diameter of the counterweight bulk cargo 2 is smaller than the inner diameter of each connecting pipeline, so that the counterweight bulk cargo 2 can move between the cavities along the connecting pipelines. Preferably, in order to control the direction of movement of the bulk weight 2, a valve (not shown in the figures) is arranged on each connecting pipe.
The following will explain the process of adjusting the center of gravity of the counterweight device by taking the first cavity filled with the counterweight bulk material 2 in advance as an example:
when compressed air is introduced into the first cavity 11, negative pressure is formed in the second cavity 12 and the third cavity relative to the first cavity 11, and the counterweight bulk material is sucked into the second cavity 12 and the third cavity, so that the gravity center of the counterweight device is transferred to one side where the second cavity 12 and the third cavity are located; of course, it is also possible to close the valve on the fifth connecting pipe between the first chamber 11 and the third chamber to control the movement of the counterweight bulk material between the first chamber 11 and the second chamber 12.
In this embodiment, through the pressure value of the compressed air who lets in the cavity and the gas volume that lets in of adjusting, can control the weight that the counter weight that takes place to shift packs, and then control the change amount of this counter weight device's focus position, realize many grades of counter weight focus positions of adjusting.
The invention adopts a mode of filling the counterweight bulk material in the cavity, and the counterweight bulk material is transferred in the cavity through pneumatic conveying, thereby realizing the transfer of the counterweight gravity center; in addition, the counterweight device has a simple structure and is easy to operate.
The structure of the counterweight device will be described in more detail below by taking as an example a case where two cavities are formed in the box body 1.
As shown in the figure, the cavity formed in the box body 1 of the counterweight device comprises a first cavity 11 and a second cavity 12, the side walls of the first cavity 11 and the second cavity 12 are respectively provided with a first air inlet 31 and a second air inlet 32, and the first cavity 11 and/or the second cavity 12 are filled with counterweight bulk materials 2.
Specifically, the first cavity 11 and the second cavity 12 are two closed cavities, the first air inlet 31 is communicated with the first cavity 11, and the second air inlet 32 is communicated with the second cavity 12 through a connecting pipeline, which may be a circular pipe. The first cavity 11 is filled with the counterweight bulk material 2, and the counterweight bulk material 2 can be steel shots, namely steel balls in a circular shape, an oval shape or other shapes, and can also be counterweight bulk material made of other materials; in order to allow the bulk weight material 2 to be transferred between the first cavity 11 and the second cavity 12, the diameter of the bulk weight material 2 is smaller than the diameter of the communication channel between the first cavity 11 and the second cavity 12.
It should be noted that: during specific implementation, the bulk weight material 2 can be filled in the first cavity 11 and/or the second cavity 12 in advance according to actual needs, but the bulk weight material 2 cannot be filled in the two cavities, so that the bulk weight material 2 can move in the two cavities.
The gravity center adjusting process of the counterweight device is as follows: when compressed air is introduced into the first cavity 11 through the first air inlet 31, negative pressure is formed in the second cavity 12 relative to the first cavity 11, steel shots are sucked into the second cavity 12, and the gravity center of the counterweight device is shifted to one side of the second cavity 12; similarly, when compressed air is introduced into the second cavity 12 through the second air inlet 32, the steel shots can also be sucked back into the first cavity 11, so that the center of gravity of the counterweight device is shifted to the side where the first cavity 11 is located.
It can be seen that the quantity of the steel shots which are transferred can be controlled by adjusting the pressure value of the compressed air introduced into the first cavity 11 or the second cavity 12 and the introduced gas quantity, so that the variation of the gravity center position of the counterweight device is controlled, and the counterweight gravity center position is adjusted in multiple gears.
