Description

화물 하역용 굴삭기{Cargo excavator}Cargo excavator

본 고안은 유체압으로 작동되는 동력 굴삭기의 유체압공급부에 엔진용 펌프와 전기 모타용 펌프를 나란히 장치하여 엔진 또는 전기 모타의 힘으로 유체압펌프를 작동시켜 굴삭기를 작동시킬 수 있게 구성하므로서 유체압 작동용 엔진이 고장날 경우 전기모우터를 이용하여 유체압 펌프를 작동시켜 지속적인 하여 작업을 달성할 수 있도록 한 것이다.The present invention is equipped with the engine pump and the electric motor pump side by side in the fluid pressure supply of the hydraulic excavator operated by the hydraulic pressure to operate the hydraulic pump by the power of the engine or electric motor to operate the excavator In the event of a failure of the engine, the electric motor is used to operate the hydraulic pressure pump so that the work can be continuously performed.

종래의 하역 작업용 굴삭기는 포크레인과 같이 유체압을 동력으로 하는 중장비에 굴삭용 삽날을 장치하여 유체압을 동력원으로 유체압 펌프를 작동시켜 작업을 하고 있으나 유체압 펌프를 작동시키는 중장비의 엔진이 고장나면 수리시까지 하역작업이 중단되어야 하는 불편이 있었다.Conventional unloading excavators work by operating a hydraulic pressure pump with a hydraulic pressure as a power source by installing an excavation blade on heavy equipment powered by a hydraulic pressure, such as a fork crane, but when the engine of a heavy equipment that operates a hydraulic pressure pump fails Unloading work had to be stopped until repaired.

본 고안은 위와같은 종래의 결점을 시정하기 위하여 개발한 것으로 첨부도면에 의거 상세히 설명하면 다음과 같다.The present invention has been developed in order to correct the above-mentioned drawbacks as described in detail based on the accompanying drawings.

기계 본체(1)의 작동간(2)(2a)에 굴삭용 삽날(3)을 장치하여 3종류의 유체압 실린더(4)(4a)(4b)로 작동간과 굴삭용 삽날(3)을 작동시켜 무개화차(5)에 적재된 화물(6)을 하역하는 공지된 것에 있어서 기계 본체(1)의 하부에 대차(7)를 장치하여 궤도용 바퀴(9)를 달아 레일(10) 위에서 이동되게 구성하고 유체 공급용 펌프를 엔진용 펌프(11)와 모타용 펌프(12)로 구분하여 나란히 설치한 다음 엔진용 펌프(11)의 구동부에는 엔진(13)의 구동부를 접속하고 모타용 펌프(12)의 구동부에는 전기모타(14)의 구동부를 접속하여 엔진용 펌프 또는 모타용 펌프중에서 선택한 펌프로 유체압을 공급하여 하역작업기를 작동시킬 수 있게한 구성이다.본 고안에서 엔진용 펌프와 모타용 펌프는 공지의 제품을 이용하므로 별도의 설명은 생략하였다.The excavation blade 3 is installed between the operation body 2 and 2a of the machine main body 1 to operate the operation blade and the excavation blade 3 with three types of hydraulic cylinders 4, 4a and 4b. In the known method for unloading the cargo 6 loaded on the flat car 5, the trolley 7 is installed at the lower part of the main body 1 so that the track wheel 9 is attached to be moved on the rail 10. The fluid supply pump is divided into an engine pump 11 and a motor pump 12 and installed side by side. Then, the driving part of the engine pump 11 is connected to the driving part of the engine pump 11 and the motor pump 12 ) Is connected to the driving unit of the electric motor 14 to supply a fluid pressure to the pump selected from the engine pump or the motor pump to operate the unloading machine. Since the pump uses a known product, a separate description is omitted.

또한 본 고안은 도 3과 같이 유압펌프 구동기어(G)에 모타와 엔진을 나란히 설치하여 모타(14)의 구동기어(14a)와 엔진(13)의 구동기어(13a)를 유압펌프 구동기어(G)에 접촉시키는 동력전환접속장치(20)를 구비하여 유압펌프를 작동시키는 것이 포함된다.미설명부호 16은 오일탱크, 16a는 오일필터, 17은 콜트롤러, 19,19a는 릴리프밸브이다.In addition, according to the present invention, the motor and the engine are installed side by side in the hydraulic pump driving gear G as shown in FIG. 3 to convert the driving gear 14a of the motor 14 and the driving gear 13a of the engine 13 into the hydraulic pump driving gear ( And operating a hydraulic pump with a power switching connecting device 20 in contact with G). Reference numeral 16 denotes an oil tank, 16a an oil filter, 17 a colloidal controller, and 19 and 19a a relief valve.

이와같이 된 본 고안은 전기를 이용하여 모타를 작동시키고 그 힘으로 엔진을 작동시켜 그 힘으로 엔진용 펌프를 작동시키는 것이 가능하고 모타용펌프(12)를 구동시키거나 유체압 펌프의 구동부(G)에 엔진과 모타를 나란히 장치하여 동력전환접속장치(20)를 통해 모타 또는 엔진의 동력을 유압펌프작동에 이용할 수 있기 때문에 하역작업현장에서 어느하나가 고장이 날 경우 이를 선택적으로 사용하여 계속적인 하역작업이 가능케되고 또 굴삭기가 대차위에 장치되어 레일을 따라 움직이기 때문에 하역 전문 굴삭장치의 설치가 가능하여 능율적인 하역시설을 구성할 수 있으며 하역장비의 가동율을 높힐 수 있고 운정방법에 변함이 없어 장비운전자는 누구나 편리하게 사용할 수 있는 이점을 얻을 수 있어 생산성을 높힐 수 있는 것이다.The present invention is thus capable of operating the motor using electricity and the engine by the force to operate the engine pump by the force, and to drive the motor pump 12 or the driving portion (G) of the hydraulic pressure pump Since the engine and the motor can be installed side by side in the power conversion connection device 20 to use the power of the motor or the engine for the hydraulic pump operation, if any one of the unloading sites fails, it can be used continuously. Since the operation is possible and the excavator is installed on the bogie and moves along the rail, it is possible to install the unloading specialized excavator to construct an efficient unloading facility, increase the operation rate of the unloading equipment, and do not change the operation method. Anyone can benefit from the convenience of using it, which can increase productivity.
