Description

Breaker force control and anti-batting system {A System for batting Control and no batting of Constrbattinguction Machine}

The present invention by the operation of setting the turning force of the adjustment of the impact force of the breaker and the anti-hit prevention part of the breaker which is installed outside the cylinder of the hydraulic breaker, which is a hydraulic impact machine, to the cylinder and the piston of the breaker through the blow control valve The present invention relates to a breaker's striking force control and anti-striker system for smoothly performing hitting and smashing and smashing of the striking rod operated by the striking rod. By the operation of selectively rotating to the position of the (H) and the weak (L), anti-ball (X), the ball and blow force control valves and the high pressure in the high-pressure pipe is operated by actuating the blow and direction control unit for the blow force control and anti-ball Discharges to hydraulic discharge pipe through weak and smashing conversion path Accordingly, to prevent damage of the lower structure such as the front head and the hitting rod pin of the breaker when the breaker strikes, and the high pressure flowing into the high-pressure pipe through the hitting and hitting force control valves to switch or weakened conversion port In order to adjust the stroke of the piston, it is possible to adjust the stroke of the piston.In the case of the crushing operation that requires a large impact force such as rock fracture, the stroke of the piston is increased to increase the impact force of the impact rod, such as soft rock or concrete crushing. During operation, it is possible to reduce the striking force of the striking rod by reducing the stroke of the piston, and to control the striking force of the breaker and to prevent the striking, smashing and weakening of the striking rod operated by the breaker piston. It is about.

Generally known hydraulic breaker, when the blow rod hits the crushing object and completely crushed, the blow rod is in a floating state in the air, at this time the hitting rod is lowered due to its own weight for the blow The lower end of the piston and the upper end of the striking rod are in a relaxed state. In this case, the striking piston performs a reciprocating operation, so that the striking piston does not strike the striking rod, but performs the striking operation of striking the empty space. When such a hit occurs, the piston hits the inner wall of the front head and impacts it, thereby causing damage to the assembly (rod pin, thrust ring, front cover, etc.) mounted inside the front head. , There is a disadvantage that the life of the hydraulic breaker is greatly reduced.

On the other hand, in the Republic of Korea Patent No. 10-0675586, in order to prevent the blow of the hitting rod, the hydraulic recovery passage for sending the hydraulic pressure from the bypass chamber, the upper and lower hitting bumps, the low pressure passage in the hitting bumps inside the cylinder On the other hand, by installing a separate first and second sensors for turning on and off the select switch by detecting the pressure change of the hydraulic pressure of the anti-jamming jaw from low pressure to high pressure, the impact rod of the hydraulic breaker Prevent unnecessary blow operations of the piston striking the cylinder.

However, in the case of the breaker having the conventional breaker anti-battery structure as described above, a separate first for detecting the pressure change of the separate upper and lower hitch bumps and the hitch bumps to turn on and off the select switch. And the structure is complicated by the installation of the second sensor, due to the characteristics of the breaker is subjected to extreme impact force and vibration, there is a problem that the breakout bump and the first and second sensors, etc. easily breakage occurs.

In addition, in the case of the hydraulic breaker, it is difficult to control the striking force through the striking rod, the operation of the striking rod is always made in a constant state, and recently, as in Republic of Korea Patent Publication No. 2009-0041823 By installing a separate automatic adjustment valve on the control valve in the cylinder of the cylinder, the blow force of the breaker through the automatic adjustment valve can be automatically adjusted, while hitting soft rock and concrete that does not require a large blow force such as a rock lamp, etc. Struck operation is frequently caused even when the rod is hit by the rod, and the automatic adjustment valve is easily damaged due to the extreme impact force and vibration generated when the breaker is hit by the breaker.

SUMMARY OF THE INVENTION The present invention has been made to improve the above-mentioned conventional problems, and an object thereof is to provide a hydraulic inlet pipe with an accumulator and a high-pressure pipe, which controls the piston hitting the striking rod inside the cylinder of the breaker. The high pressure pipe is communicated with each other, and the hydraulic outlet pipe and the low pressure pipe communicated with each other are communicated with each other via a pipeline control valve. At one end of the high pressure pipe, an anti-static pipe line and the air ball to control the stroke of the piston are provided.

It is communicated with the valve, and the lower portion of the sluice switching pipe is the hydraulic leakage through the low pressure pipe. The struck and blow force control valve is installed in the opening and closing of the breaker cylinder by addressing the blow force adjustment and the anti-ball turn direction switching unit rotatably installed outside the breaker cylinder, thereby adjusting the blow force installed on the outside of the breaker cylinder. And by the operation to selectively rotate the direction switching unit for the hitting prevention (H) and weak hitting (L), anti-ballout (X), the hitting and hitting force control valve spoke with the hitting force control and anti-hit switching direction It operates to discharge the high pressure of the high-pressure pipe through the hydraulic and sluice conversion line to the hydraulic discharge pipe to prevent the occurrence of ball strike, and thus to prevent damage of the lower structure such as the front head and the hitting rod pin of the breaker when the breaker strikes. High pressure flows into the high pressure pipe through the struck and the force control valve By selectively flowing into the swash changeover port or the weak changeover port, it is possible to adjust the stroke of the piston.In case of the crushing operation requiring a large impact force such as breaking the rock, the stroke of the piston is increased to increase the impact of the impact rod. In case of work such as soft rock or concrete crushing, it is possible to reduce the stroke of the hitting rod by reducing the piston stroke, and the hitting force of the breaker that can smoothly perform the hitting, smashing and weakening of the hitting rod operated by the breaker's piston. It is to provide a regulation and anti-mitigation system.
