크레인차량용 전자척시스템{A magnetic chuck for crane car}Electronic chuck system for crane vehicle {A magnetic chuck for crane car}

본 발명은 크레인 차량에 장착되어 철제 대상물을 자력을 이용하여 부착함으로서 이동하는 크레인차량용 전자척시스템에 관한 것이다. The present invention relates to an electronic chuck system for a crane vehicle which is mounted on a crane vehicle and moves by attaching an iron object using magnetic force.

전자척이란, 일반적으로 크레인차량의 다단붐의 단부에 연결되어, 주위의 철제 대상물을 자력으로 부착하여 이동하기 위한 것이다. 이러한 전자척은, 다단붐의 단부에 체인에 의하여 연결되는 척본체와, 척본체에 내장되는 것으로서 코일이 권회된 코어와, 척본체에 설치되어 코일의 2선이 연결되는 단자와, 단자와 연결되어 + 및 - 전원을 인가하는 케이블을 포함한다. An electromagnetic chuck is generally connected to the end of a multistage boom of a crane vehicle, and is for moving and attaching the surrounding iron object by magnetic force. The chuck has a chuck main body connected to the end of the multi-stage boom by a chain, a core in which the coil is wound as built in the chuck main body, a terminal installed at the chuck main body and connected to two wires of the coil, and connected to the terminal. And + and-cables to apply power.

이러한 구조에 의하여, 전자척이 체인에 의하여 크레인차량의 다단붐에 연결된 상태에서, 케이블의 +극은 크레인차량 전원의 + 단자와 연결되고, -극은 크레인차량 전원의 -극과 연결된다. 이 상태에서, 크레인차량의 전원으로부터 발생된 전류는 코일을 흐르게 되고, 이에 따라 강한 자력이 발생되어 코어는 철제 대상물을 부착시키는 자력을 발생하게 된다. With this structure, in the state where the electromagnetic chuck is connected to the multi-stage boom of the crane vehicle by the chain, the + pole of the cable is connected to the + terminal of the crane vehicle power supply, and the-pole is connected to the-pole of the crane vehicle power supply. In this state, the current generated from the power supply of the crane vehicle flows through the coil, whereby a strong magnetic force is generated so that the core generates a magnetic force to attach the iron object.

그런데 상기한 구조의 전자척이 사용되는 환경은 매우 가혹하기 때문에, 전자척이 철재 대상물을 부착 및 운반하는 과정에서 철재대상물의 접촉에 의하여 케 이블이 벗겨져 합선되거나 파손되는 경우가 많았고, 이에 따라 전자척시스템의 작동이 멈추곤 하였다. However, since the environment in which the electronic chuck of the above structure is used is very harsh, the cable is peeled off due to the contact of the steel object in the process of attaching and transporting the steel object. The chuck system would stop working.

또한 전자척의 사용이 완료된 이후에 케이블은 전자척시스템에 감겨진 상태로 보관된다. 그런데, 케이블이 감겨진 상태로 전자척을 이동하는 과정이나 전자척을 다단붐에 연결하는 과정에서 케이블이 손상되는 경우가 있었다.In addition, after the use of the chuck is completed, the cable is stored in the chuck system. However, there have been cases where the cable is damaged in the process of moving the electronic chuck with the cable wound or connecting the electronic chuck to the multi-stage boom.

더 나아가 전자척이 보관되는 장소는 주차장에 주차된 크레인차량의 적제함이나 창고인 경우가 많은데, 케이블이 전자척과 함께 보관되므로 한 겨울에 저온에 의하여 케이블의 피복이 파손되는 경우가 많았고, 이에 따라 전자척을 사용하지 못하게 되었다라는 문제점이 있었다. Furthermore, the place where the electronic chuck is stored is often a storage box or warehouse of a crane vehicle parked in a parking lot. Since the cable is stored together with the electronic chuck, the sheath of the cable is often damaged by a low temperature in the winter. There was a problem that the use of the electronic chuck was not available.

본 발명은 상기와 같은 문제점을 해결하기 위하여 창출된 것으로서, 가혹한 환경에서 운영되는 과정에서 전원을 인가하기 위한 케이블이 손상되거나 합선되는 것을 방지할 수 있는 크레인차량용 전자척시스템을 제공하는 것을 목적으로 한다.The present invention was created to solve the above problems, and an object of the present invention is to provide an electronic chuck system for a crane vehicle that can prevent the cable for applying power in the process of operating in a harsh environment to prevent damage or short-circuit. .

착탈식케이블(50)은, 척본체(10)에 설치된 제1착탈잭(30)과 다단붐(M)에 설치된 제2착탈잭(40)에 선택적으로 착탈되는 것이다. 이를 위하여 착탈식케이블은 제1착탈잭(30)에 착탈되는 제3착탈잭(53)과, 제2착탈잭(40)에 착탈되는 제4착탈잭(54)과, 제3착탈잭(53)과 제4착탈잭(54)을 연결하는 케이블(55)을 포함한다. The detachable cable 50 is selectively detached from the first detachable jack 30 provided in the chuck body 10 and the second detachable jack 40 provided in the multi-stage boom M. FIG. To this end, the detachable cable includes a third detachable jack 53 detachable from the first detachable jack 30, a fourth detachable jack 54 detachable from the second detachable jack 40, and a third detachable jack 53. And a cable 55 connecting the fourth detachable jack 54.

제3착탈잭(53)은, 도 6에 도시된 바와 같이, 제1착탈잭(30)의 플러그-인을 위한 소켓홈(53a)과, 소켓홈(53a) 내부에 설치되는 철심링(53b)과, 철심링(53b)의 바닥측에 설치되는 영구자석(53c)을 포함한다. As shown in FIG. 6, the third detachable jack 53 has a socket groove 53a for plug-in of the first detachable jack 30 and an iron core ring 53b installed inside the socket groove 53a. ) And a permanent magnet 53c installed on the bottom side of the iron core ring 53b.

제4착탈잭(54)은, 도 6에 도시된 바와 같이, 원통형상의 철심봉(54a)과, 철 심봉(54a)을 감싸는 절연체(54b)를 포함한다. As shown in FIG. 6, the fourth detachable jack 54 includes a cylindrical iron core rod 54a and an insulator 54b surrounding the iron core rod 54a.

케이블(55)은 피복제(55a)로 감싸여진 전선(55b)을 포함하며, 전선(55b)은 제3착탈잭(53)의 철심링(53b)과 제4착탈잭(54)의 철심봉(54a)과 연결된다. The cable 55 includes an electric wire 55b wrapped with a covering 55a, and the electric wire 55b is an iron core bar 53b of the third attachment and detachment jack 53 and an iron core rod of the fourth attachment and removal jack 54. Connected with 54a.

상기와 같은 구조에 의하여, 전자척시스템을 사용하고자 할 경우, 척본체(10)를 다단붐(M)의 단부에 연결한 후, 착탈식케이블(50)을 이용하여 제1착탈잭(30)과 제2착탈잭(40)을 전기적으로 연결한다. 그러면 코일의 일측단(C1)은 척본체(10) 및 다단붐(B)을 통하여 전원(G)의 - 극과 전기적으로 연결되고, 코일의 타측단(C2)은 착탈식케이블(50) 및 전원케이블(W)에 의하여 전원의 + 극(단자 ; G1)과 연결된다. By the structure as described above, if you want to use the electronic chuck system, after connecting the chuck body 10 to the end of the multi-stage boom (M), using the removable cable 50 and the first removable jack 30 and The second detachable jack 40 is electrically connected. Then, one end C1 of the coil is electrically connected to the negative pole of the power source G through the chuck body 10 and the multistage boom B, and the other end C2 of the coil is a detachable cable 50 and a power source. It is connected to the + pole (terminal; G1) of the power supply by the cable (W).

이때 제1,2착탈잭(30)(40)과 착탈식케이블의 제3,4착탈잭(53)(54)은 자력에 의하여 순간적으로 접속되므로, 착탈이 매우 용이하다. 이후, 전자척시스템을 보관하거나 이동할 때에는, 착탈식케이블(50)을 잡아당겨서 제1,2착탈잭(30)(40)으로부터 분리한다. At this time, since the first and second detachable jacks 30 and 40 and the third and fourth detachable jacks 53 and 54 of the detachable cable are instantaneously connected by magnetic force, detachment and detachment are very easy. Thereafter, when storing or moving the electronic chuck system, the removable cable 50 is pulled and separated from the first and second detachable jacks 30 and 40.

이때, 착탈식케이블(50)은, 도 5에 도시된 바와 같이, 집게(T)의 상부측을 통과하여 다단붐(M)의 제2착탈잭(40)에 착탈되므로, 전자척이 철제대상물을 부착 및 운반하는 과정에서 철제대상물에 의하여 착탈식케이블(50)이 접촉되거나 파손되는 것을 방지할 수 있다. 즉, 어떠한 가혹한 환경에서도 착탈식케이블이 손상되거나 합선되는 것을 방지할 수 있음으로써, 보다 안정적으로 전자척시스템을 운용할 수 있다. At this time, the detachable cable 50, as shown in Figure 5, passing through the upper side of the tong (T) to be detached to the second detachable jack 40 of the multi-stage boom (M), the electronic chuck to the iron object The detachable cable 50 may be prevented from being touched or damaged by the iron object in the process of attachment and transport. In other words, it is possible to prevent the detachable cable from being damaged or short-circuited in any harsh environment, and thus the electronic chuck system can be operated more stably.

또한, 전자척시스템을 사용하지 않을 때나 운반시, 착탈식케이블을 분리하여 따뜻한 장소에 보관할 수 있어, 겨울에 착탈식케이블 피복이 손상되는 것을 방지할 수 있고, 이에 따라 한겨울에도 전자척시스템을 사용할 수 있다.In addition, when the electronic chuck system is not used or transported, the detachable cable can be removed and stored in a warm place, thereby preventing damage to the cover of the detachable cable in winter, and thus the electronic chuck system can be used even in the winter. .

그리고, 작업도중 전자척시스템인 다단붐으로부터 분리되어 떨어질 경우에, 착탈식케이블이 자연스럽게 분리됨으로써 그 착탈식케이블이 손상되는 것이 방지될 수 있다. In addition, when the detachable cable is separated from the multi-stage boom which is an electronic chuck system during the operation, the detachable cable may be naturally separated, thereby preventing the detachable cable from being damaged.
