Description

Technical Field

[0001] The utility model relates to the field of electrical system control, in particular to a magnetic induction type limiting device of a rigid dummy rod collecting system. Background Art

[0002] The rigid dummy bar collecting system is an important device for guiding the continuous casting billet during the pouring process of the billet continuous casting machine. The limit device is used to accurately stop the control signal during the electrical control process of the dummy bar collecting system.

[0003] Normally, the limit switch of the rigid dummy rod collecting device of the billet continuous casting machine is an opener and a shutter. The opening and closing points of the opener and the shutter collect signals, and after being programmed by the PLC control system, the dummy rod collecting system is controlled to stop accurately. The opener and the shutter are easily affected by the vibration generated during the production process, resulting in the mistransmission of signals, causing the continuous casting machine to fail to start casting, wasting a lot of manpower and material costs. Utility Model Content

[0004] In view of the above problems, the utility model provides a magnetic induction limit switch for a rigid dummy rod collection system, which is used to solve the problem that the continuous casting machine fails to start casting due to erroneous signal transmission during the casting process, thereby wasting a large amount of manpower and material costs.

[0005] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0006] A magnetic induction limit device for a rigid dummy rod collection system comprises a magnetic induction limit switch which is arranged on a collection device box and is connected to a PLC control system signal. A magnet is installed on the dummy rod in an adjustable position, wherein the position of the magnetic induction limit switch is on the movement trajectory of the dummy rod.

[0007] The dummy rod is provided with a positioning groove, and the magnet can be installed in the positioning groove.

[0008] A limit mounting bracket is arranged on the collection device box, and a magnetic induction limit switch is arranged on the limit mounting bracket.

[0009] A hole is opened in the middle of the limit mounting bracket for mounting a magnetic induction limit switch.

[0010] The beneficial effects of the utility model are:

[0011] (1) The utility model does not directly contact the dummy rod. The electromagnetic induction limit switch changes the induction signal only when the magnet enters its induction range and is not affected by vibration. The control procedure is simple and the process maintenance is convenient.

[0012] (2) The utility model can adjust the limit position of the magnetic induction limit switch by adjusting the installation position of the magnet in the positioning groove.

[0013] (3) A limit mounting bracket is provided on the collecting device box of the utility model, and a magnetic induction limit switch is provided on the limit mounting bracket, which is simple to install and convenient to disassemble and assemble.

[0014] (4) The utility model has a hole in the middle of the limit mounting bracket for mounting a magnetic induction limit switch, which is easy to install and disassemble. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0019] like Figure 1 As shown, a magnetic induction limit device of a rigid ingot rod collection system includes a magnetic induction limit switch 1, which is arranged on a collection device box 2, and the magnetic induction limit switch is connected to the PLC control system signal, and a magnet 5 is installed on the ingot rod 3 with an adjustable position, wherein the position of the magnetic induction limit switch 1 is on the movement trajectory of the ingot rod 3.

[0020] like Figure 1 As shown, the dummy rod 3 is provided with a positioning groove 4, and the magnet 5 can be installed in the positioning groove 4.

[0021] like Figure 1 As shown, a limit mounting bracket 6 is provided on the collecting device box 2 , and the magnetic induction limit switch 1 is provided on the limit mounting bracket 6 .

[0022] like Figure 1 The middle position of the limit mounting bracket 6 is provided with a hole for mounting the magnetic induction limit switch 1 .

[0023] When the utility model is used, the magnetic induction limit switch 1 does not directly contact the dummy rod 3, which solves the problem that the performance of the original rigid dummy rod 3 collection system is unstable during operation. The magnet 5 enters its sensing range along with the dummy rod, and its sensing signal changes. The signal of the magnetic induction limit switch 1 is turned on, and the signal is transmitted to the PLC control program to realize the accurate stop of the control system.

[0024] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations, modifications, and substitutions made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
