Embodiment 1
[0078] 1. Install the docking mechanism 200
[0079] Determine the axle of the blast furnace skip car 10 that needs to be refueled, install the hydraulic cylinder at the corresponding position of the first station 31, install the bracket 220 on the piston rod 212 of the hydraulic cylinder, install the refueling pipeline 300 on the bracket 220, and the hydraulic cylinder pushes the refueling pipeline 300 Forward and backward, and make the refueling pipeline 300 just aligned with the second oil inlet of the externally threaded straight-through pipe joint 130 during the forward and backward strokes.
[0080] 2. Install oil inlet pipe mechanism 100
[0081] According to the size of the inner diameter of the 10 wheels of the blast furnace skip car, a rectangular frame 120 is made. After the blast furnace skip car 10 moves to the first station 31 and starts feeding, take off the hole cover of the oil inlet hole 11 of the tanker to be refueled, and install two jacking bolts at one e...

The invention provides an online fueling method for a blast furnace skip car and a blast furnace charging system, and relates to the technical field of blast furnace feeding. The online fueling methodfor the blast furnace skip car is used for refueling when the blast furnace skip car reciprocates between a first station and a second station, and after the blast furnace skip car arrives at the first station, a refueling pipeline is in butt joint with an oil inlet pipe mechanism to start oil delivery; after the blast furnace skip car finishes feeding or when the oil pressure of a wheel shaft isgreater than or equal to 10kPa, oil delivery is stopped, and the fueling pipeline is separated from the oil inlet pipe mechanism by a butting mechanism. The wheel axle of the blast furnace skip car is fueled in the charging time of the blast furnace skip car, online fueling of the blast furnace skip car in the working state is achieved, the defect that the blast furnace skip car cannot be fueleddue to the fact that a blast furnace has no damping-down plan for a long time is overcome, and high yield of the blast furnace is consolidated. And the online fueling method can be used for fueling the wheel axle at any time according to the condition of the wheel axle, is beneficial to the maintenance of the wheel axle and the blast furnace skip car, and avoids a series of accidents caused by aggravated wear of the wheel axle of the blast furnace skip car during high-speed operation.
Description
technical field [0001] The present application relates to the technical field of blast furnace charging, and in particular, relates to an online refueling method for a blast furnace skip car and a blast furnace charging system. Background technique [0002] At present, most furnaces have a capacity of 1000m 3 Class blast furnaces basically use double blast furnace charging cars. A single blast furnace skip car includes a car body and 4 wheels. The car body is used to load the furnace material, and the main winch motor rotates to drive the wire rope to run, thereby pulling the wheels of the blast furnace skip car to run. During the charging process, the charge is loaded into the car bucket according to the set weight, and the wheels are pulled by the wire rope to run on the track, and the charge is transported to the hopper on the top of the blast furnace to achieve the purpose of charging the blast furnace. Under normal circumstances, the time for the blast furnace skip ca...
