Problems solved by technology

If there is a stuck brazing accident, the on-site workers need to go to the furnace to cut off the drill pipe by flame (oxygen flame welding), which has a great safety risk and greatly affects the production efficiency of the blast furnace equipment; and because the drill pipe needs to be cut off, it is also increased production costs

Embodiment Construction

[0046] The present invention will be further described below in conjunction with the embodiments and the accompanying drawings. It is noted that the terms "first", "second" and the like are only for the purpose of facilitating description, and should not be construed as limitations on quantity and nature.

[0047] figure 1 A schematic structural diagram of an existing blast furnace hydraulic opening machine is shown, such as figure 1 As shown, the blast furnace hydraulic opening machine 700 includes a rock drill 730 and a trolley 740 that pushes the rock drilling machine 730; the blast furnace hydraulic opening machine automatic control system provided by the embodiment of the present invention can perform hydraulic control on this type of blast furnace hydraulic opening machine. The trolley 740 is driven by the propulsion motor 720 to achieve forward advancement and retraction, thereby pushing the rock drill 730 to advance and retreat. The drill rod 770 of the rock drill 73...

Abstract

The invention discloses an automatic control system of a blast furnace hydraulic tapping machine and the blast furnace hydraulic tapping machine, and belongs to the technical field of metallurgical equipment. The system comprises a main control valve group, a rotation oil way, a propulsion oil way, an impact oil way and a reverse oil way, wherein the rotation oil way comprises a forward rotation oil way and a reverse rotation oil way; the propulsion oil way comprises a forward oil way and a backward oil way; the impact oil way comprises an impact oil inlet way and an impact oil return way; the reverse oil way comprises a reverse oil inlet way and a reverse oil return way; the rotation oil way, the propulsion oil way and the impact oil way are all connected with the main control valve set. A propulsion control valve set is arranged on the propulsion oil way and connected with the forward rotation oil way. An impact control valve set is arranged on the impact oil inlet oil way and connected with the retreating oil way. And a reverse-hitting control valve group is arranged on the reverse-hitting oil inlet oil way and is connected with the retreating oil way. The blast furnace hydraulic tapping machine comprises the control system. The drill rod clamping prevention device can effectively prevent drill rod clamping in the blast furnace opening process.

Description

technical field [0001] The invention belongs to the technical field of metallurgical equipment, and in particular relates to an automatic control system of a blast furnace hydraulic opening machine and a blast furnace hydraulic opening machine. Background technique [0002] Blast furnace ironmaking is a relatively common ironmaking method at present. Opening operation is a crucial production link in front of the blast furnace. Opening operation is to pierce the tap hole of the blast furnace through the opening machine equipment, so that the molten iron generated in the blast furnace can pass through the hole of the tap hole. discharge. During the opening operation, the blast furnace hydraulic opening machine is used to carry out the opening operation. [0003] During the working process of the blast furnace hydraulic opening machine, due to the complex working conditions, the operator in front of the furnace needs to stand in front of the furnace and frequently operate the ...
