제2도는 본 고안의 작동상태를 나타내는 사시도이다.2 is a perspective view showing an operating state of the present invention.

3 : 리미트스위치 4 : 하부프레임3: limit switch 4: lower frame

5 : 캠 5a : 상부면5: cam 5a: upper surface

본 고안은 중장비의 중행방향 표시장치에 관한 것으로, 특히 선회할 수 있도록 된 상부프레임을 갖춘 중장비의 중행방향을 운전자가 용이하게 확인할 수 있도록 한 중장비의 주행방향 표시장치에 관한 것이다.The present invention relates to a driving direction display device of heavy equipment, and more particularly, to a driving direction display device of the heavy equipment to enable the driver to easily check the running direction of the heavy equipment equipped with the upper frame to be able to turn.

일반적으로 하부프레임상에서 선회할 수 있도륵 된 상부프레임을 갗춘 크로울러(crawler)형식의 중장비에 있어서 운전자가 상부프레임을 좌. 우로 회전시켜가면서 작업을 하다보면 자칫 주행방향을 확인할 수 없는 경우가 있었다.In general, the crawler type heavy equipment with the upper frame designed to be able to swing on the lower frame allows the operator to seat the upper frame. When you work while rotating to the right, you could not check the driving direction.

따라서, 운전자는 주행방향을 확인하기 위해 주위의 작업환경을 살펴보고 주행방향을 찾거나, 아니면 하부프레임을 미소한 거리만큼 주행시켜서 그 진행방향을 확인한 다음, 주행의 전. 후진방향을 결정하여 중장비를 주행시켜 왔던바, 만일 작업공간이 좁거나, 급경사진 작업장과 같이 운전자의 세심한 주의가 요구되는 작업장에서 운전자가 주행방향을 오인하여 중장비를 주행시켜주게 되면 안전사고를 초래할 염려가 크다고 하는 문제점이 있었다.Therefore, in order to check the driving direction, the driver looks around the work environment and finds the driving direction, or moves the lower frame by a small distance to confirm the driving direction, and then before driving. Since the driving direction of heavy equipment has been determined by reversing the direction, if the driver misunderstands the driving direction and runs the heavy equipment in a workplace that requires close attention, such as a steep incline workplace, it may cause a safety accident. There was a problem that concern was great.

즉, 상부프레임과 하부프레임이 정 또는 역방향으로의 배열상태에 따라 방향전환하기 위한 운전조작방향을 서로 달리 해주어야 하는바, 만일 상, 하부프레임이 역방향의 배열상태일 때 정방향으로 배열된 경우와 같이 같이 조작해주면 좌우전환방향이 달라져 안전사고의 위험이 발생할 수 있는 것이다.That is, the operation operation direction for changing the direction according to the arrangement of the upper frame and the lower frame in the forward or reverse direction must be different from each other, as if the upper and lower frames are arranged in the forward direction when the reverse frame is arranged in the reverse direction If operated together, the left and right switching direction may change, which may cause a risk of a safety accident.

이에 본 고안은 상기와 같은 문제점을 해소시켜 주기위해 안출된 것으로, 상부프레임의 하부면에 그 선회중심의 전방쪽으로 편심되게 접촉로울러를 갖춘 리미트스위치가 부착되고, 이 리미트스위치의 아랫쪽 하부프레임의 스위블조인트부위에 "C"자형 캠이 장착된 구조로 되어, 상기 상부프레임이 회전되면서 리미트스위치가 상기 캠에 접속/분리됨에 따라 리미트스위치가 ON/OFF되면서 운전실내의 계기판에 부착된 방향표시등을 점멸시켜 주도록 되어, 운전자가 용이하게 주행방향을 확인할 수 있도록 된 중장비의 주행방향 표시장치를 제공함에 그 목적이 있다.The present invention is devised to solve the above problems, the lower surface of the upper frame is attached to the limit switch with a contact roller eccentrically toward the front of the pivot center, the swivel of the lower lower frame of the limit switch The C-shaped cam is mounted on the joint, and as the upper frame is rotated, the limit switch is turned on / off as the limit switch is connected / disconnected to the cam, and the direction indicator attached to the instrument panel in the cab blinks. The purpose of the present invention is to provide a driving direction display device for heavy equipment that allows the driver to easily check the driving direction.

이하 본 고안을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 고안은 제1도 및 제2도에 도시된 바와 같이 상부프레임(1)의 하부면에 그 선회중심의 전방쪽으로 편심되게 접촉로울러(2)를 갖춘 리미트스위치(3)가 부착되고, 이 리미트스위치(3)이 아랫쪽으로 하부프레임(4) 윗면의 선회중심부위 즉, 스위블조린트부위에는 상기 상부프레임이 회전됨에 따라 같이 선회하게 되는 리미트스위치(3)의 기상적인 궤적에 대응되도륵 "C"자형 캠(5)이 전방쪽으로 편심되게 장착되며, 이 캠(5)은 상부면(5a)과, 그 양끝이 상기 리미트스위치(3)의 접촉로울러(2)가 쉽게 구르면서 겁촉되도록 비스듬히 잘려진 경사부(5b)를 갖추고 있다.According to the present invention, as shown in FIGS. 1 and 2, a limit switch 3 having a contact roller 2 is attached to the lower surface of the upper frame 1 so as to be eccentrically toward the front of its pivot center. Even if the switch 3 is turned downward to correspond to the meteorological trajectory of the limit switch 3, the pivot center portion of the upper surface of the lower frame 4, that is, the swivel joint part, is rotated together as the upper frame is rotated. "The cam (5) is mounted eccentrically toward the front, the cam (5) is cut off at an angle so that the upper surface (5a) and both ends of the contact roller (2) of the limit switch (3) are easily rolled and scared. The inclination part 5b is provided.

또한 제2도에서 화살표 A는 전진방향, B는 후진방향을 나타내고, 화살표 C-C'로 표시된 구역은 후술하는 방향표시등의 점등구역을 나타낸다.In FIG. 2, arrow A indicates a forward direction, B indicates a reverse direction, and an area indicated by arrow C-C 'indicates a lighting area of a direction indicator described later.

한편, 상기 리미트스위치(3)는 운전실 계기판의 방향묘시등에 직렬로 연결되고, 이 방향표시등은 시동키이 및 측전지에 직렬연결되어 시동키이가 OFF된 상태에서 방향표시등이 동작하지 않도륵 되어 있다.On the other hand, the limit switch 3 is connected in series to the direction drawing light of the cab instrument panel, the direction light is connected to the start key and the side battery in series so that the turn indicator does not operate while the start key is turned off.

다음 본 고안의 작동을 설명한다.Next, the operation of the present invention will be described.

운전자가 시동키이를 ON시켜 축전지(8)로 부터 전원이 방향표시등에 가해진 상태에서, 작업도중 상부프레임(1)을 전방쪽으로 선회시켜주게 되면 이 상부프레임(1)에 부착된 리미트스위치(3)의 집촉로울러(2)가 하부프레임(4)의 윗면에 장착된 "C"자형 캠(5)의 경사부(5b)를 타고 넘으면서 상부면(5a)위를 구르게 되므로 상기 리미트스위치(3)의 접점이 ON되어져 방향표시등이 점등되게 된다.When the driver turns the ignition key on and turns the upper frame 1 forward while the power is applied to the direction indicator from the battery 8, the limit switch 3 attached to the upper frame 1 The limit switch (3) is rolled over the upper surface (5a) while passing through the inclined portion (5b) of the "C" shaped cam (5) mounted on the upper surface of the lower frame (4) Will turn on and turn on the indicator.

따라서 상기 방향표시등은 리미트스위치(3)의 접촉로울러(2)가 상기 캠(5)의 상부면(5a)에 접촉되는 한 계속 켜져 있게 되므로 운전자는 현재 하부프레임(4)의 주행방향이 전진방향이라는 것을 알 수 있게 된다.Therefore, the direction indicator light remains on as long as the contact roller 2 of the limit switch 3 is in contact with the upper surface 5a of the cam 5, so that the driver is currently running in the forward direction of the lower frame 4. You can see that.

이와 반대로, 상부프레임(1)이 회전되어 상기 캠(5)의 상부편(5a)으로 부터 리미트스위치(3)의 접촉로울러(2)가 벗어나게 되면, 이 리미트스위치(3)가 OFF되면서 방향표시등이 꺼지게 되므로, 운전자가 현재 하부프레임(4)의 주행방향이 후진방향이라는 것을 확인할 수 있게 되며, 만일 이 경우 운전자가 중장비룰 전진방향으로 주행시키고자 할 경우에는 상부프레임(1)을 다시 반대로 회전시켜 상기 설명에서와 같이 방향표시등이 점등된 것을 확인한 다음, 주행하면 되는 것이다.On the contrary, when the upper frame 1 is rotated so that the contact roller 2 of the limit switch 3 is released from the upper piece 5a of the cam 5, the limit switch 3 is turned off and the direction indicator light is turned off. Since it is turned off, the driver can confirm that the current driving direction of the lower frame (4) is the reverse direction, in this case, if the driver wants to drive in the forward direction of heavy equipment, the upper frame (1) is rotated again After confirming that the direction indicator is turned on as described above, the vehicle may be driven.

한편, 시동키이를 OFF시켜주게 되면 축전지로 부터 전원이 차단되게 되므로 방향표시등은 동작하지 않게된다.On the other hand, if the start key is turned off because the power is cut off from the battery, the direction indicator does not operate.

이상의 설명에서와 같이 본 고안은 리미트스위치(3)의 접촉로울러(2)가 "C"자형 캠(5)의 상부면(5a)에 접촉된 상태에서만 방향표시등이 켜지도록 되어, 운전자가 작업도중 주행방향을 쉽게 확인할 수 있게 되어 편리함과 더불어 주행방향의 착오로 인한 안전사고를 미연에 방지할 수 있게 되는 것이다.As described above, the present invention is to turn on the indicator light only when the contact roller 2 of the limit switch (3) is in contact with the upper surface (5a) of the "C" shaped cam (5), the driver during the operation The driving direction can be easily checked, and convenience and safety accidents due to errors in the driving direction can be prevented in advance.
