Hydraulic control system of iron making blast furnace repairing and dismounting robot

Abstract

The invention discloses a hydraulic control system of an iron making blast furnace repairing and dismounting robot. The hydraulic control system of the iron making blast furnace repairing and dismounting robot comprises a pressure supply mechanism, a first control mechanism, a second control mechanism and a heat extraction device, wherein the pressure supply mechanism comprises a flow dividing element, the input end of the first control mechanism is connected with one output end of the flow dividing element and used for controlling a vehicle body to travel, the input end of the second controlmechanism is connected with the other output end of the flow dividing element and used for controlling a first dismounting and mounting mechanical arm to act, the second control mechanism comprises aplurality of control assemblies arranged in parallel, at least one control assembly comprises a pressure maintaining element, the output end of the first control mechanism and the output end of the second control mechanism are connected to the heat extraction device, and the output end of the heat extraction device is connected to the pressure supply mechanism. According to the hydraulic control system, the robot can be integrally controlled, the pressure in the system is kept stable through the pressure maintaining element, the stable and reliable action of the robot can be ensured, and the cyclic utilization of hydraulic oil liquid is realized.

Description

technical field [0001] The invention relates to special equipment for blast furnace disassembly and maintenance, in particular to a hydraulic control system for an ironmaking blast furnace inspection and disassembly robot. Background technique [0002] In blast furnaces in steel mills, in addition to the direct blow pipe of the air supply branch pipe, the corrugated pipe of the air supply branch pipe, the small tuyere sleeve, and other components such as the tuyere middle sleeve, often need to be replaced and repaired. At present, the maintenance and disassembly of blast furnaces is generally done manually, which requires several workers to operate at the same time, which is labor-intensive and low in efficiency. Moreover, since the blast furnace wind jacket generally weighs several hundred kilograms, personal injury accidents are very likely to occur during disassembly. In addition, when dismantling the wind jacket of the blast furnace, it may be encountered that the wind j...

AI Technical Summary

Problems solved by technology

At present, the maintenance and disassembly of blast furnaces is generally done manually, requiring several workers to operate at the same time, which is labor-intensive and low-efficiency, and because the blast furnace wind jacket generally weighs several hundred kilograms, personal injury accidents are very likely to occur during disassembly

In addition, when disassembling the blast furnace air jacket, it may be encountered that the air jacket is melted into one body by the molten iron in the furnace, which is equivalent to the air jacket being welded.

In this case, the difficulty of manual work is increased

[0003] Now there are also some blast furnace wind jacket dismantling equipment, but these devices often have a single function, and can only repair and disassemble one of the air supply branch pipe, the air supply branch pipe bellows, the tuyere small sleeve, and the tuyere middle sleeve.

At the same time, these devices still need manual assistance during actual operation, and cannot realize integrated and automated operations.

[0004] In addition, due to the heavy weight of the blast furnace wind jacket, if it is tilted or overturned during the disassembly process, it will cause serious injury to the operator and the disassembly equipment.
