Description

1 / the invention relates to the field of controlling the chemical composition of the molten metal, in particular, to devices for installing samplers, and can be used in manipulators for inserting sensors into the bed.

The circuit of the invention is to increase the efficiency and reliability of operation.

The drawing shows a sampling probe, a general view.

The sampling probe contains a housing 1, inside of which is placed the rod 2 with the collar 3 and the rod 4 for mounting the sampler 5. On the stem of the rod 2 a locking ring 6 is installed. In addition, the rod 2 is equipped with two sealing rings, rings 7 and 8. with a sleeving sleeve 9. Case 1 is provided with a sleeve 1 o rigidly fixed on its end face, and inside the sleeve 10 is installed as possible (by moving

sleeve 11. The sleeve 11 is rigidly connected to the plug 12 of the electric connector 13. The bracket 14 is movably mounted inside the sleeve 11 and is spring-loaded relative to it by means of a spring 15. A microswitch 16 is placed on the side surface of the bracket 14, and the pin 17 prevents the vertical movement of the bracket 14 relative to additional bushing 11. A groove 18 is made on the bracket 14, which ensures that the distance between the microswitch 16 and the ring 19 is unchanged during axial movements of the rod 2, as well as during oscillations of the axial position v LKI 11, e.g., after dismantling and subsequent mounting. The electrical connector 13 is fixedly mounted on the nozzle 20 of the manipulator (not shown). The gaps between the sealing rings 7 and 8 and the rod 2 should be minimal to prevent breakthrough of hot gases from the side of the sampler 5 to the microswitch 16.

Zoid works as follows. Before being immersed in the melt of the sampler 5, the probe body 1 takes a position with the lower position of the rod 4. At the same time, under the weight, the rod 4 with the rod 2 is displaced down to the stop by the locking ring 6 at the end of the sealing ring 8. In this position, the stem of the rod 2 moves away from the microswitch 16 When the sampler 5 strikes the surface of the melt, it, together with the rod 4, is displaced inside the housing 1 until the shoulder 3 stops against the end of the sealing ring 7, and the stem of the rod 2 interacts with the microswitch 16 and, as a result, is outputted from drove the cayne by the melt level sampler 5, after which the manipulator worked out the predetermined depth of the sampler 5. The hot gases escaping from the gap between the sampler 5 and the rod 4 cannot break through to the microswitch 16 and remove the probe from the system, since the gases must first overcome three steps of the rolling seal — valve pair formed by the flange 3 and the end of the ring 7, the slotted seal between the ring 7 and the stem 2, and the slotted seal between the rod 2 and the ring 8. Coking of the stem 2 during operation remove the probe without removing it by vigorously turning and axial movements of the wand 4 with the rod 2 relative to the housing 1 and the rings 7 and 8. Removing the probe from the pipe 20 is done by unscrewing the sleeve 10. Twisting and breaking the wires from the plug 12 to the switch does not occur since the sleeve 11 remains stationary, and thanks to the pin 17, the bracket 14 with the switch 16 also remains stationary. After unscrewing the sleeve 10, it together with the housing 1 and with the rod 4 is somewhat removed from the nozzle 20. Thereafter, the probe can be completely removed. Monitoring of the probe's operability is carried out by checking the mobility of the wand 4 with the rod 2 in the housing 1 and the operation of the switch 16.

The positive effect of using the probe manifests itself in increasing its efficiency due to the possibility of simplifying the design of the manipulator and optimizing the manufacturability of the probe itself.
