본 고안은 건설중장비에서 사용되는 타격장치의 타격수 측정장치에 관한 것으로, 특히 타격시 발생되는 충격압을 이용하여 타격수를 측정할 수 있게 되므로써 타격장치의 부품교환시기를 쉽게 알 수 있음과 더불어 타격장치의 정격타격수에 맞는 유량을 굴삭장치에 정확하게 설정할 수 있도록 된 타격장치의 타격수 측정장치에 관한 것이다.The present invention relates to a hitting number measuring device of the hitting device used in construction equipment, in particular, it is possible to easily know the timing of replacement parts of the hitting device by being able to measure the number of hits using the impact pressure generated during the hitting The present invention relates to an apparatus for measuring the number of hits of a striking device, which enables to accurately set a flow rate corresponding to the rated stroke number of a device in an excavator.

일반적으로 타격장치에 사용되는 부품은 노후화됨에 따라 그 부품을 교환해 주어야 하는 바, 이와 같은 부품 교환시기를 결정하는 인자 중의 하나로 타격장치의 타격수를 측정하여 일정한 타격수 이상이 되면 부품을 교환해 주도록 되어 있다.In general, the parts used in the hitting device must be replaced as they age. As one of the factors that determine when to replace these parts, the number of hitting devices is measured. It is meant to be given.

한편, 타격장치를 굴삭장치에 부착하여 사용할 때는 타격장치에 요구되는 유량을 굴삭장치에 설정해 주어야 하는데, 설정유량은 타격수를 비례적으로 증가시키므로 사용된 총 통과유량을 측정할 수 있다면 타격공구의 총 타격수를 계산할 수 있다.On the other hand, when attaching the striking device to the excavator, the flow rate required for the striking device should be set in the excavator. The set flow rate increases the number of blows proportionally, so if the total flow rate used can be measured, The total number of hits can be calculated.

그래서, 종래에는 타격수를 측정하기 위해 유량측정기구가 널리 사용되고 있으며, 유량측정기구가 없을 때는 작업자가 타격장치를 작동시켜 실제 타격에서 발생하는 타격수를 경험을 통해 파악하여 유량을 설정하기도 한다.Thus, in the related art, a flow rate measuring mechanism is widely used to measure the number of hits, and when there is no flow rate measuring mechanism, the operator operates the hitting device to set the flow rate by grasping the number of hits generated by the actual hitting through experience.

그런데 종래의 유압측정기구는 고가의 장비이고, 사용상에 주의가 요구되는 정밀기기이므로 충격 및 진동이 심한 작업장에서 사용하기가 어려울 뿐만 아니라 타격수를 경험을 통해 파악하는 것은 정확성이 떨어지고, 경험자가 아닐 때에는 타격수에 맞는 유량을 설정하기 어렵다는 문제점이 있었다.However, the conventional hydraulic measuring instruments are expensive equipment and are precision instruments that require attention in use, so they are not only difficult to use in the workplace with severe shock and vibration, but are also inaccurate in determining the number of hits through experience. At this time, there was a problem that it is difficult to set the flow rate for the hitting water.

이에 본 고안은 상기한 바와 같은 제문제점을 해결하기 위해 안출된 것으로, 타격시 발생되는 충격압을 이용하여 타격수를 측정할 수 있게 되므로써 타격장치의 부품교환시기를 쉽게 알 수 있음과 더불어 타격장치의 정격타격수에 맞는 유량을 굴삭장치에 정확하게 설정할 수 있는 타격장치의 타격수 측정장치를 제공함에 그 목적이 있다.Therefore, the present invention was devised to solve the problems described above, so that the number of blows can be measured using the impact pressure generated when the hitting device, so that it is easy to know when to replace parts of the hitting device. It is an object of the present invention to provide an impact measuring device of a striking device that can accurately set a flow rate corresponding to a rated hitting speed in an excavator.

상기한 바의 목적을 달성하기 위한 본 고안은, 타격장치의 저압측에 설치되는 체결플러그를 관통하여 저압호스가 설치되어 있고, 이 저압호스의 일단에 실린더가 설치되어 있으며, 이 실린더에 연결되어 실린더캡 및 카운터부가 설치되어 있는 한편, 상기 실린더 내부에 설치되어 있는 피스톤과 실린더캡 내부 사이에 스프링 및 카운터바가 연결설치되어 있고, 상기 카운터부는 전기신호발생기와 카운터로 이루어져 있다.The present invention for achieving the above object is, a low pressure hose is installed through the fastening plug installed on the low pressure side of the striking device, a cylinder is provided at one end of the low pressure hose, and is connected to the cylinder A cylinder cap and a counter part are installed, while a spring and a counter bar are connected between the piston and the cylinder cap installed inside the cylinder, and the counter part comprises an electric signal generator and a counter.

이러한 구조로 이루어진 본 고안에 따르면, 타격이 이루어짐에 따라 타격장치 내 저압축의 작동유가 상기 실린더 내부로 유출입이 반복되어 피스톤에 연결설치된 스프링과 카운터바가 왕복운동되어 카운터부에 의해 타격수가 측정되어 정확한 타격수를 알 수 있게 되는 것이다.According to the present invention having such a structure, as the blow is made, the hydraulic fluid of the low compression in the blow device is repeatedly flowed in and out of the cylinder, and the spring and the counter bar connected to the piston are reciprocated to measure the number of blows by the counter. The number of hits will be known.

이하 본 고안을 첨부한 예시도면을 참조하여 자세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제 1도 및 제 2도는 본 고안에 따른 타격수 측정장치의 작동 전, 후 상태를 개략적으로 나타낸 것으로서, 타격장치(1)의 저압측에 설치되는 체결플러그(2)를 관통하여 저압호스(3)가 설치되어 있고, 이 저압호스(3)의 일단에 실린더(4) 가 설치되어 있으며, 이 실린더(4)에 연결되어 실린더캡(5) 및 카운터부(6)가 설치되어 있는 한편, 상기 실린더(4) 내부에 설치되어 있는 피스톤(7)과 실린더캡(5) 내부 사이에 스프링(8) 및 카운터바(9)가 연결설치되어 있고, 상기 카운터부(6)는 전기신호발생기(10)와 카운터(11)로 이루어져 있다.1 and 2 are views schematically showing the state before and after the operation of the blow water measuring apparatus according to the present invention, the low pressure hose (3) through the fastening plug (2) installed on the low pressure side of the hitting device (1) ), A cylinder 4 is provided at one end of the low pressure hose 3, and a cylinder cap 5 and a counter portion 6 are connected to the cylinder 4, A spring 8 and a counter bar 9 are connected between the piston 7 installed in the cylinder 4 and the inside of the cylinder cap 5, and the counter part 6 includes an electric signal generator 10. ) And a counter 11.

상기와 같은 구조로 이루어진 본 고안에 따른 장치는, 타격장치(1)의 저압측에 형성된 출입구(12)를 통해서 작동유의 압력이 작용되면, 상기 타격장치(1)의 저압측과 체결플러그(2)를 관통하여 실린더(4)에 연결설치되어 있으면서 상기 출입구(12)에 연결된 저압호스(3)를 통하여 실린더(4) 내부에 삽입되어 있는 피스톤(7) 압력이 작용하게 되는 것이다.The device according to the present invention having the structure as described above, when the pressure of the hydraulic oil is applied through the entrance 12 formed on the low pressure side of the striking device 1, the low pressure side and the fastening plug (2) of the striking device (1) The pressure of the piston (7) inserted into the cylinder (4) is acted through the low pressure hose (3) connected to the cylinder (4) while being connected to the cylinder (4) through.

따라서, 타격장치(1)가 작동되기 시작하여 타격장치(1)의 저압측에 타격에 의한 충격압 또는 압축에 의하여 작동유의 압력상승이 이루어져, 이 작동유압이 실린더(4) 내의 피스톤(7)을 밀어주고 있는 스프링(8)력보다 커지면 피스톤(7)이 뒤로 밀려나 H위치로부터 L위치에까지 밀려나게 됨에 따라 상기 피스톤(7)에 연결된 카운터바(9)도 함께 이동하게 되어 상기 실린더캡(5)에 연결설치된 전기신호발생기(10)에 타격신호를 전달하여 전기적신호가 발생하게 되며, 이 전기적신호에 따라 카운터(11)에 타격수가 입력되어지는 것이다.Accordingly, the striking device 1 starts to operate, and the pressure of the hydraulic oil rises by the impact pressure or the compression caused by the striking on the low pressure side of the striking device 1, and this hydraulic pressure causes the piston 7 in the cylinder 4 to rise. When the force of the spring 8 is greater than the pushing force, the piston 7 is pushed backwards and is pushed from the H position to the L position, so that the counter bar 9 connected to the piston 7 moves together with the cylinder cap 5. An electric signal is generated by transmitting a blow signal to the electric signal generator 10 connected to the electric signal generator 10, and the blow water is input to the counter 11 according to the electric signal.

그리고, 타격장치(1)의 저압측에 작용되는 작동유압이 피스톤(7)을 밀고 있는 스프링(8)력보다 작아지면, 상기 피스톤(7)은 L위치로부터 H위치로 이동되어 1사이클이 완성되는 것이다.When the hydraulic pressure acting on the low pressure side of the striking device 1 is smaller than the force of the spring 8 pushing the piston 7, the piston 7 is moved from the L position to the H position to complete one cycle. Will be.

이상에서 설명한 바와 같이 본 고안에 따르면, 타격장치(1)에 의해 타격이 이루어짐에 따라 그 충격압이 주기적으로 형성되어 타격장치(1) 내 저압측의 작동유가 상기 실린더(4) 내부로 유출입이 반복되어지며, 이에 따라 피스톤(7)에 연결설치된 스프링(8)과 카운터바(9)가 왕복운동되어 상기 카운터부(6)에 의해 타격수가 측정되어 정확한 타격수를 알 수 있게 되는 것이다.As described above, according to the present invention, the impact pressure is periodically formed as the impact is caused by the striking device 1 so that the hydraulic oil of the low pressure side in the striking device 1 flows in and out of the cylinder 4 repeatedly. Accordingly, the spring 8 and the counter bar 9 connected to the piston 7 are reciprocated so that the number of hits is measured by the counter part 6 so that the correct number of hits can be known.

또한, 상기와 같이 정확한 타격수를 알 수 있게 되므로써 타격장치의 부품 교환시기를 정확히 알 수 있게 되어 작업중 부품교환 등에 의한 작업중단을 피할 수 있게 됨과 더불어 정격타격수에 맞는 유량을 굴삭장치에 설정시켜 줄 수가 있는 것이다.In addition, by knowing the exact number of blows as described above, it is possible to know exactly when to replace the parts of the hitting device to avoid interruption of work due to the replacement of parts during work, and to set the flow rate to the excavator to match the rated number of hits I can give it.
