Rotary table positioning device

Abstract

The invention relates to a rotary table positioning device. The rotary table positioning devices are arranged in pairs. The rotary table positioning device comprises a linear driving device, a sliding bearing, a telescopic rod and a positioning head, wherein the linear driving device is connected with one end of the telescopic rod; the positioning head is arranged at the other end of the telescopic rod; and the telescopic rod is connected with a support through the sliding bearing. Compared with the prior art, the rotary table positioning device has the benefits that firstly after adoption of the novel rotary table positioning device, the positioning precision of a stopping position after rotation of a rotary table can be improved, and the positioning error is limited within 0.1mm; and secondly in combination with the conventional positioning structure, the rotary table is positioned more reliably.

Description

technical field [0001] The invention relates to the field of a carrier vehicle for a rotating coke pot, in particular to a positioning device for a rotating table. Background technique [0002] The rotary coke tank carrier is the equipment used to transport high-temperature coke in the process of dry coke quenching. The upper part is equipped with a rotating platform, which carries the rotating coke tank for coke connection and other operations. During the coking process of the coke pot, the rotary table drives the coke pot to rotate to achieve uniform coking. After the rotating coke tank completes the coke receiving operation, the carrier vehicle walks from the coke receiving place in the carbonization chamber to the lifting derrick for the next step of operation. [0003] In the prior art, the positioning of the rotary table after each focusing is completed is realized by a motor with a rotary encoder and a limit switch at the lower part of the rotary table. Due to the l...

AI Technical Summary

Problems solved by technology

Due to the limitations of the structure and precision of the limit switch and the rotary encoder and the rotational inertia of the coke pot, the positioning accuracy of the stop position after the rotation of the turntable is not high, which may easily lead to operational failure of the rotating coke pot placed on the turntable when it is lifted
