Description

Technical Field

[0001] The utility model relates to the technical field of automobile sampling equipment, in particular to automobile sampling equipment with a movable limiting device. Background Art

[0002] Active lime is one of the important raw materials for steelmaking. Its quality affects the quality of molten steel. Therefore, its inspection results are crucial to the control process of steelmaking production process. The detection of active lime components is inseparable from the sampling of samples. At present, the sampling of active lime adopts the method of automatic sampling by car. The automatic sampling machine of the car is a double-beam bridge structure. There are trolley tracks and trolley running mechanisms on the beam. There are lifting frames on the inside of the two running mechanisms of the trolley. The lifting frame is a frame structure with round columns at the four corners, top plates and bottom plates above and below. The lifting frame moves with the trolley, and the main body cannot be raised or lowered. There is a movable car in the lifting frame, which is pulled up and down by the lifting motor on the top plate. There is a drill motor in the car, and the sampling rod and sampling drill bit are hung below. There is a round hole on the bottom plate of the lifting frame below the drill bit, and the drill rod can pass freely. When sampling, the movable car descends, driving the drill bit to descend to the specified height. The drill bit rotates during the descent process to take samples. After the sampling is completed, the movable car is lifted to the upper limit position to wait for the next task.

[0003] Inductive proximity switch sensors are installed at the upper and lower limit positions of the lifting frame. When the rising limit position sensor detects the metal frame at the upper edge of the movable car, the upper limit positioning signal is triggered. When the falling limit position sensor detects the metal frame at the lower edge of the movable car, the lower limit positioning signal is triggered.
