Maintenance device of air pipe of blast furnace

Abstract

The invention discloses a maintenance device of an air pipe of a blast furnace, which comprises a vehicle chassis, a power system, a platform, a lifting device of the platform, a containing seat of the air pipe and a transverse movement device of an air pipe seat, wherein the vehicle chassis comprises a transmission mechanism, a running mechanism and a braking mechanism and can run on the platform below the air pipe of the blast furnace; the power system is arranged on the vehicle chassis and provides power for the running of a vehicle; the platform is arranged above the vehicle chassis; the lifting device of the platform is installed on the vehicle chassis, connected with the platform and used for controlling the platform to move along a direction vertical to the vehicle chassis; the containing seat of the air pipe is arranged above the platform and used for placing the air pipe; and one end of the transverse movement device of the air pipe seat is connected with the containing seat of the air pipe, the other end of the transverse movement device of the air pipe seat is connected with the platform, and the transverse movement device of the air pipe seat is used for enabling the containing seat of the air pipe to transversely move relative to the platform. After the structure is adopted, the vehicle chassis can control the device to move to the lower part of the air pipe of the blast furnace. When the air pipe is assembled and disassembled, the platform can move to a proper position by the control of the lifting device, the positions of the left and the right of the containing seat of the air pipe can be adjusted by adjusting the transverse movement device of the air pipe seat, manual replacement is not needed, and the production efficiency is enhanced.

Description

(1) Technical field [0001] The invention relates to a maintenance device for a blast furnace air duct, which is used for disassembling and transferring the air duct, and belongs to the field of maintenance tools for ironmaking blast furnace air supply equipment. (2) Background technology [0002] In blast furnaces for ironmaking, hot air is sent into the furnace through air supply equipment and tuyeres. The air supply equipment includes bent pipes and straight blow pipes, which are collectively referred to as blast furnace air pipes. Sometimes the air duct needs to be replaced. Due to the heavy weight of the air duct and the narrow space around the blast furnace, large lifting equipment cannot be used to replace the air duct. It can only be replaced manually, which is time-consuming and laborious, and affects production. [0003] In order to solve the above problems, the utility model patent No. 200520079875 of the State Intellectual Property Office of China discloses a dev...

AI Technical Summary

Problems solved by technology

[0005] 1. The contact area between the air duct and the hydraulic mechanism is small, and the movement of the air duct is not very stable during the lifting process;

[0006] 2. The bearing force of the lever is limited, and the service life of the device is short
