The present invention relates to a steering sensor device of a tire driving gantry crane, and to a steering sensor device of a tire driving gantry crane, which comprises: a wheel yoke frame (20) supporting a tire wheel (10); and an electric cylinder (30), and changes a direction of the tire wheel by the power of the electric cylinder according to a driving mode. A steering disc (100) in which a plurality of grooves (100) are spaced apart from each other along a circumference is coupled to the wheel yoke frame (20), and a limiter switch (120) is installed in the wheel yoke frame (20) to correspond to each of the grooves. When the electric cylinder (30) is operated according to a steering mode to rotate the tire wheel (10) coupled to the wheel yoke frame (20), the steering disc (100) coupled to the wheel yoke frame (20) is rotated therealong, and a front end of the limiter switch (120) is inserted into the groove (110) such that it is confirmed that the tire wheel (10) is correctly rotated according to the steering mode. Accordingly, the present invention is advantageous in that when the steering wheel of the tire driving gantry crane is rotated, the steering sensor is operated in conjunction with the rotation of the steering wheel, such that a steering rotation angle can be accurately sensed, and in that the steering sensor can be manufactured at reduced costs.

    본발명은 타이어구동 겐트리크레인의 조향센서 장치에 관한 것으로, 타이어 바퀴(10)를 지지하는 휠 요크 프레임(Wheel Yoke Frame)(20)과 전동실린더(30)로 구성되어, 운전모드에 따라 전동실린더의 힘으로 상기 타이어 바퀴의 방향을 바꾸는 타이어구동 겐트리크레인의 조향센서 장치에 있어서, 상기 휠 요크 프레임(20)에는 여러 개의 홈(110)이 원주를 따라서 이격되어 형성되는 조향 디스크(100)가 결합되고, 상기 각각의 홈에 대응되게 리미터스위치(120)가 설치되어, 조향모드에 따라 상기 전동실린더(30)가 동작되어 휠 요크 프레임(20)에 결합된 타이어바퀴(10)를 회전시키면 상기 휠 요크 프레임(20)에 결합된 조향 디스크(100)가 따라서 회전하고, 상기 홈(110)에 리미터스위치(120)의 선단이 삽입되어 조향모드에 맞게 타이어 바퀴(10)가 정확히 회전한 것을 확인하는 것으로, 본발명은 타이어구동 겐트리크레인의 조향바퀴 회전시 연동하여 조향센서가 동작함으로써 조향회전각도를 정확히 감지할 수 있으며, 조향센서의 제조단가가 저렴해지는 현저한 효과가 있다.
