A rh vacuum tank repairing device

Abstract

The invention discloses an RH vacuum tank building device. The RH vacuum tank building device comprises a building trolley, wherein the building trolley comprises a frame; the frame is a three-layer steel structure frame; a lifting mechanism is fixed on the top layer, and a lifting platform is hung on the lifting mechanism; the lifting mechanism is electrically connected with a lifting controller and is controlled by the lifting controller; a mobile controller and a driving mechanism are installed on the bottom layer of the frame; the driving mechanism is electrically connected with the mobile controller and is controlled by the mobile controller; a straight ladder is arranged between the middle layer and the bottom layer of the frame. The driving mechanism is controlled by the mobile controller, so that the building trolley is horizontally moved to the building position; the lifting mechanism is controlled by the lifting controller for providing power to the lifting platform, and then the lifting mechanism is declined from the upper tank to the tank body and the worker can enter the tank; when the lifting platform reaches the position near the bottom part of the lower tank, a cover plate trolley is moved away, and the worker descends to the bottom part of the lower tank to build through an opened manhole. The tank body placing position and the work plane height are reduced and the lifting route of the building platform is shortened. The RH vacuum tank building device has the characteristics of reliable lifting and convenient and safe operation.

Description

technical field [0001] The invention relates to a tank body repairing device in metallurgical equipment, in particular to a RH vacuum tank repairing device. Background technique [0002] In the metallurgical industry, there are a large number of tanks that are in contact with high-temperature molten steel, gas, and liquid and are scoured by their high-speed flow. These tanks are often required to be in the shape of a cylindrical shell due to requirements or limitations of the environment, process, and equipment facilities to form various large chambers or passages, especially for vacuum tanks of RH external refining devices. Under the high-speed erosion of high-temperature medium, the inner walls of these tanks are often lined with refractory bricks or refractory mud. The refractory bricks or refractory mud need to be replaced after a certain period of use to ensure the safe operation of the facilities. In particular, RH vacuum tank refractory materials are frequently repai...

AI Technical Summary

Problems solved by technology

This method satisfies the requirements for building refractory materials for the upper tank of the split RH vacuum tank, but does not meet the requirements for integrally building refractory materials for the upper and lower tanks, reducing the efficiency of building different tanks

Obviously, both of these methods have defects of low security and low efficiency
