in the figure, a workbench 1, a through groove 2, a vortex sensor 3, a first lifting rod 4, a rotating shaft 5, a lever supporting seat 6, an anchor bolt 7, a second lifting rod 8, an auxiliary 9 cylinder, a lifting cylinder 10 and a handle 11.
Detailed Description
The utility model is described in further detail below with reference to the embodiments of the drawings.
As shown in FIG. 1, the rapid lifting device for the vortex sensor in the embodiment comprises a workbench, wherein the workbench is covered on the top of a crystallizer, and a through groove is formed in the workbench and is communicated with the inner cavity of the crystallizer. Be equipped with the supporting seat on the workstation, the supporting seat is fixed in on the workstation through 4 rag bolts of symmetrical arrangement, and rag bolt not only can guarantee the stability of supporting seat, can adjust the difference in height of lifting rod and workstation moreover. The supporting seat top is equipped with the lifting rod that the level was arranged, and the lifting rod articulates on the supporting seat through the pivot. The bottom of one end of the lifting rod is provided with a vertically arranged lifting cylinder, the other end of the lifting rod is provided with an eddy current sensor, the eddy current sensor is arranged in the through groove, the lifting cylinder drives one end of the lifting rod to move upwards, the lifting rod rotates around the rotating shaft, so that the other end of the lifting rod moves reversely (moves downwards), and the eddy current sensor is driven to move downwards to reach a measuring position; the lifting cylinder drives one end of the lifting rod to move downwards, the lifting rod rotates around the rotating shaft, the other end of the lifting rod moves upwards, the vortex sensor is driven to move upwards, and then molten steel is kept away from.
Above-mentioned lifting rod includes first lever and second lever, and vortex sensor sets up in first lever one end, is connected through the connecting block between first lever other end and the second lever one end, and three threaded connection can adjust the length of lifting rod, and then adapts to different occasions. The rotating shaft is arranged on the connecting block, and the supporting frames are penetrated at the two ends of the rotating shaft, so that the rotating shaft can rotate in the supporting frames. The bottom of the auxiliary piece is fixed on the extending rod of the lifting cylinder.
