Description

하역작업기Unloading machine

본 발명은 무개화차내에 적재되어 있는 화물을 편리하게 그리고 능률적으로 하역할 수 있게 구성한 하역작업장치에 관한 것으로 보다 구체적인 것은 이동대차에 버킷과 삽, 파쇄기를 나란히 장치하면서 특히 버킷에는 내부에 파쇄장치를 구비한 하역기를 만들고 하역물 낙하관에 여과망을 장치하여 덩어리를 걸러 파쇄할수 있게하므로서 편리하고 능률적인 하역이 달성될 수 있게 한 것이다.The present invention relates to an unloading work device configured to conveniently and efficiently unload cargo loaded in a flat car. More specifically, a bucket, a shovel, and a crusher are arranged side by side on a mobile truck, and in particular, a bucket has a crushing device inside. The loading and unloading machine is equipped with a filter net in the cargo drop pipe to filter the lumps so that convenient and efficient unloading can be achieved.

일반적으로 무개화차를 이용하여 운반되는 화물은 석탄이나 광물, 토사와 같이 분말 또는 덩어리가 있는 화물이므로 하역작업에 힘이 많이 든다.In general, cargo to be transported using a flat car is a cargo with powder or agglomeration such as coal, minerals, and earth and sand, so it is difficult to unload.

따라서 숙련된 노동자나 하역용 장비를 이용하는 것이 보통이다. 그러나, 석탄이나 광물 또는 토사와 같은 화물은 분말이 수분과 일정시간이 경과하면 덩어리 상태로 고형되게 되고 동절기의 경우는 결빙이 되어 단단한 덩어리로 변형이 되기 때문에 단순한 삽날로 이를 하역하는 것은 거의 불가능한 것이 현실이다.Therefore, it is common to use skilled workers or unloading equipment. However, cargo such as coal, minerals, or earth and sand becomes solid in a lump state after a certain period of time with water, and in winter, it becomes frozen and transforms into a hard mass, so it is almost impossible to unload it with a simple blade. It is a reality.

따라서 이러한 덩어리를 파쇄하는 별도의 중장비를 사용해야 하므로 부래커와 같은 고가의 장비를 구입하여 사용해야 하는데 이것은 가격이 비싸고 규모도 커서 사용에 많은 불편이 있었다.Therefore, it is necessary to use a separate heavy equipment that breaks down such agglomerate, so it is necessary to purchase and use expensive equipment such as a cracker, which is expensive and large, which is inconvenient to use.

본 발명은 이러한 종래의 결점을 시정하기 위하여 개발된 것인데 이를 첨부된 도면에 의거 상세히 설명하면 다음과 같다.The present invention was developed in order to correct these conventional drawbacks will be described in detail with reference to the accompanying drawings as follows.

도 1은 본 발명의 하역작업기가 예시되어 있다.1 illustrates an unloading machine of the present invention.

즉 본 발명은 일정높이에서 레일을 따라 왕복운동할수 있게 장치한 이동대차(1)에 수개의 회전축(201)을 수직으로 장치하여 각 회전축의 회전기어(202)를 전동기(20)의 구동기어(21)와 치합시켜 회전시킬 수 있게 만들고 각 회전축을 이동대차 하측으로 노출시켜 그 하단에 각각 지지대(2)(2a)(2b)를 부착하여 각 지지대에는 제1로드(3)와 제2로드(30)를 가설하여 유체압실린더로 승강시키고 굴절시킬 수 있게 구성하여 제2로드 하단에 버킷(4)과 삽(8)과 파쇄기(9)를 장치하고 버킷(4) 내부에 별도의 파쇄작동기(6)를 투입하여 내측은 버킷에 축핀(601)으로 연결시키고 선단은 버킷몸통과 유체압실린더(7)로 연결(602)하여 유체압실린더(7)를 통해 파쇄작동기(6)를 버킷(4)내부에서 작동시켜 면접촉시킬 수 있게 구성하며 버킷(4) 외벽에 다수의 분쇄물통과공(401)을 형성하고 파쇄작동기(6)의 내면에는 다수의 파쇄돌기(60)를 형성한 파쇄기능이 있는 버킷을 형성시켜 이를 내향으로 작동시키거나 외향으로 작동시킬수 있게 장치한다.That is, according to the present invention, a plurality of rotary shafts 201 are vertically mounted on the moving trolley 1 equipped to reciprocate along a rail at a predetermined height, thereby driving the rotary gears 202 of each rotary shaft as drive gears of the electric motor 20. 21) to make it rotate and to expose each rotating shaft to the lower side of the moving trolley, attaching the support (2) (2a) (2b) to the lower end of each of the first rod (3) and the second rod ( 30, it is constructed to be able to lift and deflect with a hydraulic pressure cylinder to install a bucket (4), a shovel (8) and a shredder (9) at the bottom of the second rod and a separate shredding actuator ( 6) The inner side is connected to the bucket with the shaft pin (601), the front end is connected to the bucket body and the hydraulic pressure cylinder (7) (602) through the hydraulic pressure cylinder (7) through the crushing actuator (6) bucket (4) It is configured to be in surface contact by operating in the inside and to form a plurality of through hole 401 in the outer wall of the bucket (4) The inner surface of the crushing actuator 6 is provided to form a bucket with a crushing function defines a plurality of crushing the projections 60 to allow this device to sikilsu inwardly operating, in working outward.

한편, 중간 지지대(2a)의 제2로드 끝에는 삽날(8)을 장치하여 삽날을 회전시키면서 유체압실린더(5)(5a)(5b)를 통해 승강과 굴절이 자유롭고 개폐작동시킬 수 있는 삽날을 구성하고 외측 지지대(2b)에는 진동모우터가 내장된 파쇄기(9)를 제2로드 끝에 장착하여 파쇄봉(90)을 돌출시키고 유체압실린더(5)(5a)(5b)를 통해 파쇄기(9)를 승강굴절 이동시킬 수 있게 하고 화차(10) 양측으로 설치된 하역물 안내통(11)상부에 여과망(12)을 설치하여서 덩어리를 걸러 안내통(11) 일측에 설치된 파쇄실(110)에서 파쇄기(5)로 파쇄할수 있게 한 장치이다.On the other hand, at the end of the second rod of the intermediate support (2a) is equipped with a blade (8) to rotate the blade while rotating and cutting through the hydraulic cylinder (5) (5a) (5b) to configure a blade that can be opened and closed freely and actuated The outer support (2b) is equipped with a crusher (9) with a built-in vibration motor to the end of the second rod protrudes the crushing rod (90) and the crusher (9) through the fluid pressure cylinder (5) (5a) (5b) To move up and down the refraction and to install the filter network 12 on the upper part of the cargo handling guide 11 installed on both sides of the truck (10) to filter the lump in the crushing chamber (110) installed on one side of the guide cylinder (11) 5) It is a device that can be shredded.

이와 같이된 본 발명은 무게화차(10) 내에 적재된 화물을 하역할때 하물이 분체이거나 분체와 비슷한 경우 삽날(8) 또는 버킷(4)을 이용하여 화차내의 화물을 버킷(4)으로 퍼올려 화차 밖에 있는 안내통(11)에 투입하므로서 하역이 달성되고 화물이 덩어리 상태로 화차내에 존재해 있을 때는 작은 덩어리의 경우 버킷(4)을 이용하여 버킷에 퍼 담은 다음 그 속에 장치된 파쇄작동기(6)를 작동시켜 버킷 내부에서 파쇄하면 분쇄물통과공(401)을 통해 분쇄되어 낙하되므로 파쇄하여 하역할 수 있고 결빙되어 덩어리로 뭉처져 있을 때는 진동파쇄기(9)의 파쇄봉(90)을 이용하여 큰 덩어리를 강재로 파쇄한 다음 버킷과 삽으로 안내통(11)에 이적시키는 하역이 가능하기 때문에 본발명의 하역작업기 하나만 있으며 혼자의 힘으로 분체는 물론 덩어리 상태로 응고된 화물의 하역을 비롯하여 결빙된 화물도 쉽게 하역이 가능케 되는 것이다.In the present invention as described above, when unloading the cargo loaded in the weighing truck 10, if the load is powdered or similar to the powder by using the blade (8) or bucket (4) to lift the cargo in the truck to the bucket (4) When unloading is achieved by feeding into the guide box 11 outside the wagon and the cargo is present in the wagon, when the loaf is present in the wagon, the small chunks are put in the bucket using the bucket 4 and then the crushing actuators 6 When the crushed inside the bucket is crushed through the crushed through hole 401 can be crushed and unloaded, and when frozen and lumped together by using the crushing rod 90 of the vibration crusher (9) Since it is possible to unload large chunks of steel and then transfer them to the buckets 11 with buckets and shovels, there is only one unloading machine of the present invention. The cargo frozen, including the handling of which will also enable easy loading and unloading.

그리고, 본 발명의 화물안내통(11)에는 투입구측에 여과망(12)이 장치되어 있어서 덩어리진 화역물이 안내통으로 들어오면 이것이 역과되어 파쇄실(110)로 보내어지고 파쇄실에서 파쇄기(15)로 파쇄되어 처리하기 때문에 덩어리가 들어오는 것을 방지할수 있으며 하역물의 정밀한 하역 처리가 가능케 된다.And, in the cargo guide box 11 of the present invention is equipped with a filter net 12 on the inlet side, when the lumped water is coming into the guide tube, this is reversed and sent to the crushing chamber 110, the crusher 15 in the crushing chamber Because it is crushed and processed, it prevents lumps from entering and enables precise handling of unloaded cargo.

그리고 본 발명의 하역기는 이동대차(1)를 이용하여 하역할 화물이 적재된 화차내에 버킷(4)이나 삽(8) 또는 진동파쇄기(9)를 안전하게 투입시킬 수 있고 버킷(4)과 삽(8) 진동파쇄기의 파쇄봉(90)은 승강굴절은 물론이고 화차내에서 회전이동도 할 수 있기 때문에 혼자의 힘으로 편리하고 능률적으로 부담없는 하역이 가능하게 되는 이점이 있으며 회전작동과 승강 및 굴절이동은 이동대차에 장치된 모우터(20)와 지지대와 로드 그리고 버킷과 삽 진동파쇄기 사이에 가설된 유체압실린더(5)(5a)(5b)(7)의 조작으로 간단하게 이루어지기 때문에 조작이 용이하고 이동대차 하나에 3가지 하역기구를 장치하였기 때문에 장소를 적게 차지 할뿐 아니라 값비싼 고가의 장비인 부래카나 포크레인 같은 중장비를 별도로 구비하지 않아도 되고 모우터(20)는 유체압모터를 이용할 수도 있어서 그 활용성이 매우 높은 편리하고 능률적인 장점을 얻을 수 있게 되는 것이며 버킷(4)은 내향으로 꼬부려 화물을 퍼담는 방법과 외향으로 장치되어 화물을 퍼담아 밀어내는 방법으로 운용되기 때문에 보다 다양하게 버킷을 이용할수 있게 되어 장지활용 효율을 최대로 높일수 있는 이점을 얻게 되는 것이다.And the unloading machine of the present invention can safely put the bucket (4) or shovel (8) or the vibration crusher (9) in the wagon loaded with cargo to be unloaded using the mobile cart (1) and the bucket (4) and shovel ( 8) The crushing rod 90 of the vibratory shredder has the advantage of being able to carry out the unloading refraction as well as the rotational movement in the wagon, which enables convenient and efficient unloading with its own power. Since the movement is simply performed by the operation of the hydraulic pressure cylinders 5, 5a, 5b, and 7 installed between the motor 20, the support, the rod, and the bucket and the shovel vibration crusher mounted on the moving trolley, Because it is easy and has three unloading mechanisms in one moving cart, it takes up less space and does not need to separately install heavy equipment such as braca or fork lane, which are expensive and expensive equipment, and the motor 20 has a fluid pressure motor. It can be used to obtain a very convenient and efficient advantage of high utilization and because the bucket (4) is operated by the method of twisting inward to load the cargo and the device installed outward to push the cargo. The bucket can be used in various ways to obtain the advantage of maximizing the utilization efficiency of the jang.
