Description
Technical Field
[0001] The utility model belongs to the field of high-temperature viscometers, and particularly relates to a position adjustment device for a high-temperature viscometer. Background Art
[0002] Continuous casting powder is an important material for protecting molten metal from oxidation and pollution during continuous casting. The viscosity of the powder is an important physical property parameter, which directly affects the formation and stability of the slag film. In actual production, a high-temperature viscometer is often used to measure the viscosity of continuous casting powder. When measuring the viscosity of continuous casting powder, the probe of the high-temperature viscometer needs to be placed into a heating furnace containing continuous casting powder, the temperature is adjusted, the high-temperature viscometer is turned on, and after the temperature is stable, the viscosity of the continuous casting powder is measured. During the measurement process, the probe of the high-temperature viscometer penetrates into the continuous casting powder through a measuring rod for viscosity measurement, and the high-temperature viscometer is fixed above the heating furnace through a fixed bracket.
[0003] Currently, for the lifting, rotating and swinging frame of a high-temperature viscometer with the patent application number 2021233986676 developed by our company, the following technical problems mainly exist: 1. The rotation of the high-temperature viscometer is controlled by a PLC control program. When there is a problem with the control program, the rotation of the high-temperature viscometer cannot be controlled, affecting the production progress; 2. The furnace body of the heating furnace for placing continuous casting powder is large in volume and very heavy. When placing the furnace body of the heating furnace, it is impossible to completely ensure that the center of the furnace body of the heating furnace corresponds to the probe of the high-temperature viscometer. The center position of the probe of the high-temperature viscometer relative to the center of the furnace body of the heating furnace often shows left and right offsets or front and back offsets, ultimately resulting in inaccurate measurement results. The existing rotating and swinging bracket of the high-temperature viscometer can only adjust the position of the probe by rotation when the high-temperature viscometer has a left and right offset. When the high-temperature viscometer has a front and back offset, only the position of the furnace body of the heating furnace can be adjusted; 3. When installing the high-temperature viscometer, because it is installed manually, the high-temperature viscometer often cannot reach the horizontal state, and the tilt angle of the high-temperature viscometer cannot be adjusted after installation. This leads to the need to reinstall the high-temperature viscometer if it is not installed in a horizontal state, which is time-consuming and laborious.
[0004] Based on the above defects existing in the prior art, a position adjustment device for a high-temperature viscometer has been developed, which can well solve the above problems existing in the prior art. Content of the Utility Model

This setting not only simplifies the steps of adjusting the high - temperature viscometer left and right, reduces the operation threshold, but also avoids the problem that the position of the high - temperature viscometer cannot be adjusted normally due to the failure of the PLC control system, ensuring the production efficiency.

When the handwheel a is rotated, the inclined gear rotates, driving the slider a to generate displacement. When the slider a of the dovetail groove slide table moves, it can drive the lower connecting plate and the slider b to move through the connecting sheet metal. This design simplifies the operation steps and realizes the forward and backward movement of the high - temperature viscometer.
[0016] The angular position table is fixedly connected to the fixed connecting piece, and the fixed connecting piece is fixedly connected to the high-temperature viscometer. Rotate the handwheel b, and through the worm and worm gear transmission inside the angular position table, the working surface of the angular position table is displaced, realizing the adjustment of the up and down inclination angle of the high-temperature viscometer, simplifying the adjustment steps, and avoiding the problem that the high-temperature viscometer often cannot reach the horizontal due to manual installation.
