Description

[Detailed description of the invention] (b) Industrial application field The present invention relates to a hydraulic stone breaking device.

(b) Conventional technology Conventionally, a hydraulic stone-splitting device has a base mounted on a rail so that it can slide freely, and a stone-splitting machine and an excavator that drills holes on the Fi board are attached to the base ↓-. The stone splitting device is configured so that it can be lowered freely, and the stone splitting device is connected and supported by the boom of an externally powered working machine, and is positioned on the side of the stone slab, and the base is slid to open the excavation. After making a hole on the stone plate by drilling, a widening piece with a wedge principle connected to the tip of the 60-split machine is inserted, and a wedge rod is inserted into the expanding piece through a hydraulic mechanism. The stone was divided by pressing down on the stone and using the expanding force of the expanding piece () to create cracks through drilling.

(c) Problems that the invention solves However, since the stone splitting device is connected to a power working machine and supported on one side of the stone plate, the stone splitting device has poor stability and cannot be moved downward. When performing stone splitting work by inserting and pressing the expanding piece of the stone splitter and the wedge rod into a hole in the stone slab, the wedge bar is fixed during the drilling in the stone slab, and the stress that occurs in the stone slab is reduced. However, there was a risk that the frame or movement of the entire device would be damaged, causing an accident such as causing the frame to erect or causing the power working machine to overturn.

(d) 11■ Questions! In the present invention, a rail is horizontally mounted on a support frame, a base is placed on the rail in a layered manner, and five left and right expansion pieces and a wedge bar are mounted on the base. , a hydraulic cylinder that raises and lowers the wedge rod, and a supporting case body that supports the base of the expansion piece, and four excavators that excavate the stone slab are arranged so as to be able to be raised and lowered, respectively. At the lower end of the support frame, a 15-frame frame stand that can be placed on a stone plate is installed in series, and during stone cutting work, the supporting case body of the descending stone υ] is connected to the stone plate. The present invention provides a hydraulic stone splitting device which is constructed so that a holding frame is clamped and fixed in between.

(E) Function In this invention, a hydraulic stone breaking device connected to a power working machine (7) is mounted on a stone plate, and the stone breaking device is supported on the stone plate by a support frame stand at the lower end of the support frame. , Slide the base into the hole that has been drilled on the stone plate using the excavator on the base, position the stone splitter above the excavation hole, and lower the stone splitter (1. The expanding piece and wedge rod are inserted into the excavation break, and the left and right expanding pieces are expanded by pushing H- of the wedge rod to perform stone breaking work. The support frame of the rock splitting device is clamped and fixed between the support case body at the tip of the machine and the top surface of the stone plate, and the wedge bar is lowered while keeping the entire stone splitting device in a stable state. When the stone breaking operation begins as it descends, even if the wedge rod and the expansion piece apply a biased load to one side during the excavation, the support frame base will not move between the supporting case body of the stone splitting machine and the top surface of the stone slab. Because it is clamped and fixed, the entire device is stable on the stone plate, and the stone plate blocks the stress of the biased load applied to the entire device, causing the support frame to become distorted (!) or the power working machine to fall over. There are things that can be done to prevent this.

(f) Effects Therefore, according to the present invention, the supporting case of the stone splitter is lowered onto the stone plate provided with the drilled hole, the expanding piece and the wedge rod are inserted into the drilled hole, and at the same time, the support case is lowered onto the stone plate provided with the drilled hole. By clamping and fixing the mounted support frame between the upper surface of the stone splitting machine and the supporting case body of the stone splitting machine, the widening action of the expansion piece caused by the lowering of the wedge rod for stone cutting work will spread the entire stone splitting machine. When a biasing load is applied, the stress generated when the expansion piece is expanded is concentrated on the support frame base, and the support frame base is clamped and fixed between the top surface of the stone plate and the support case body, so the bias load is 1J. When the machine is in a state of being received by the board, it prevents the frame of the stone υ1 device from being broken and the work equipment from rolling (fii), thereby achieving the effect of safely and reliably performing the cutting work.
