Description

Technical Field

[0001] The utility model relates to the technical field of automatic control of a cooling bed collecting stand, and more specifically, to a proximity switch position detection device affected by axial movement. Background Art

[0002] In the steel production process, continuous casting of steel billets is one of the important processes in the production system. The bending degree of steel billets directly affects the heating furnace entry rate of the steel rolling process. Therefore, it is necessary to minimize the bending of steel billets and increase the heating furnace entry rate of the steel rolling process. In the continuous casting production process, the cooling bed is mainly used to achieve uniform heat dissipation, thereby reducing the bending of steel billets.

[0003] The position change of the cooling bed collection stand during operation is determined by the proximity switch, which is generally installed at the bottom of the cooling bed collection stand, and the corresponding sensing device is installed on the transmission shaft. When the transmission shaft of the cooling bed collection stand moves axially, the proximity switch cannot receive the feedback signal of the sensing device, so that the high and low position signals of the cooling bed collection stand cannot be accurately detected, resulting in the inability of other interlocking equipment to operate normally, causing production to stop, greatly affecting the smooth progress of production and reducing production efficiency. Therefore, it is urgent to develop and design a new type of proximity switch position detection device. Utility Model Content

[0022] In this embodiment, the rotating rod 3 is installed on the central axis of the transmission shaft 1, and the rotating rod 3 is installed on the center of the transmission shaft 1 to improve the accuracy of detection.

[0023] In this embodiment, there are two proximity switches 4, and the two proximity switches 4 are located on one side of the rotating rod 3. The two proximity switches 4 are vertically installed on the mounting bracket, and are used for position detection of the high position of the transmission shaft 1 and the low position of the transmission shaft 1 respectively.

[0024] In this embodiment, the two proximity switches 4 are both photoelectric proximity switches. In other embodiments, the proximity switch 7 can be a mechanical proximity switch, an inductive proximity switch, a magnetic proximity switch, an ultrasonic proximity switch, or the like.
