The present invention relates to a gallstone machine used for, for example, a support device for such a gallstone machine.

[0002]

[Prior art]

 Conventionally, in the case of rock chiseling and excavation, brick excavation for replacing bricks in various furnaces and kilns, excavation of irregular refractory, and concrete wall chiseling and excavation of concrete buildings, etc. Hold the chisel rocker by hand and apply it to the rock or wall targeted by the bit at the tip of the chisel rocker, and activate it to repeatedly move forward and backward to perform chiseling action such as chisel rock or chisel. However, it is necessary to press the relevant part with an appropriate force, and for that reason, the target is manually pressed to identify it.

[0003]

[Problems to be solved by the device]

 On the other hand, in such a conventional chisel rock machine, the chisel machine itself has a considerable weight, and the balance is kept so that the chime rock machine does not fall down when chiseling or chisel rocks such as a flat part such as a floor surface. However, in the case of a vertical side surface or an overhead surface such as a ceiling, it is necessary to carry a chisel rock and chisel work by holding a heavy chisel machine and pressing the cutting edge of the chisel machine to the required location. However, since the pressing force due to human power at this time is required to be about 10 to 30 kg, it is necessary to press all the weight against the crushing surface and work continuously, and this work is considerably heavy work. The cutting edge of must always be sharp. Therefore, in the case of chisel rock or chisel digging work on the vertical side surface or ceiling surface, for example, an appropriate support stand is provided to reduce the work, and the chisel rock machine is supported on the predetermined support stand. There are some problems such as having to carry out the required work by pressing the cutting edge of the chisel rock machine toward the location. In addition, when the chisel rocker is held, the work environment is poor because the fragments and dust of the material excavated by the holder are scattered. Especially when excavating a vertical surface or a ceiling surface, large debris may fall, which is dangerous.

Therefore, an object of the present invention is to connect a chisel with a fluid jack to solve the above-mentioned problems in the related art, by fixing a rocker between a floor surface and a ceiling surface, and between two opposing side surfaces. A pair of a rock drill and a fluid jack is placed between a fixed supporting point and one corresponding side surface, and fluid pressure is supplied to the fluid jack to push the cutting edge of the rock drill to a desired position with the base of the fluid jack as a base point. It is to provide a chisel machine that has been made possible.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, according to the present invention, the chisel rock machine comprises a fluid rock jack mounted on the chisel rock machine body, and the fluid jack is fixed as a base point to which the fluid jack is fixed by supplying fluid pressure to the fluid rock jack. The feature is that the blade edge can be pressed to the target location.

[0006]

[Action]

 Therefore, according to the present invention, by applying the pressure fluid to the fluid jack attached to the main body of the rock drill by the above-mentioned means, the cutting edge of the rock drill is pressed to the place to be dug by using the fluid jack as a fixed base point. Since it is dug, it is possible to easily hold a heavy chisel rock machine when chiseling vertical walls or ceilings, etc., and a pressing force can be obtained by the fluid jack and it can be aimed at the object. You can easily adjust the direction of the blade of the chisel machine.

Other objects, features and advantages of the present invention will be apparent from the following detailed description in conjunction with the accompanying drawings.
