Description
The present invention relates to a striking device, and more particularly, to a striking device having a boosting device capable of increasing the efficiency of a striking device such as a breaker.
Generally, the striking device is a device for crushing concrete or rock, etc. Hereinafter, a hydraulic breaker, which is a type of striking device, will be described as an example thereof.
For example, the hydraulic breaker is filled with a compressible gas such as nitrogen gas by being injected into the gas chamber formed at the upper end of the piston in the main body, and the head of the chisel is mounted coaxially so as to be in contact with the piston at the lower end of the piston, The expansion state of the nitrogen gas in the gas chamber is converted into hammering energy that hits the head of the chisel through the piston, Such as a rock, concrete or the like, which is in contact with the ground.
SUMMARY OF THE INVENTION The present invention provides a striking device having a boosting device for improving striking efficiency to solve various problems. However, these problems are exemplary and do not limit the scope of the present invention.
According to an embodiment of the present invention, there is provided a boosing cylinder comprising: a main body having a main gas chamber; a boosting cylinder having a boosting gas chamber and connected to the main body and having an opening through which the fluid flows in and out; There is provided a striking device having a boosting device that improves striking efficiency, including a boosting piston movably installed in a cylinder to push fluid to the main body to improve striking efficiency.
And a sealing member provided between the boosting cylinder and the boosting piston to seal the boosting cylinder and the boosting piston.
And a buffer member provided in a moving direction of the boosting piston.
And a volume changing member provided in the boosting gas chamber to vary the volume of the boosting gas chamber.
The volume changing member may include a volume changing plate that is screwed to the boosting cylinder or the boosting piston and adjusts the position thereof to vary the volume.
The volume changing member may include a volumetric damper having a variable volume and provided in the boosting gas chamber to vary the booster gas chamber.
The boosting cylinder may include a first boosting cylinder and a second boosting cylinder.
The volume of the second boosting cylinder may be smaller than that of the first boosting cylinder.
The second boosting cylinder may be symmetrical with respect to the first boosting cylinder.
By controlling the gas pressure of the second boosting cylinder, the moving distance of the boosting piston can be controlled.
And a connection tube connecting the opening and the main body.
According to the embodiment of the present invention as described above, it is possible to implement a striking device having a boosting device capable of increasing the striking amount and increasing the efficiency of the striking device. Of course, the scope of the present invention is not limited by these effects.
