Problems solved by technology
[0010] The biggest problem of this mechanism is that the synchronization of the three hydraulic cylinders is not easy to achieve, the structure is complex, and there are many fault points. Once the three hydraulic cylinders are not synchronously linked, the damage to the distributor is often irreparable
[0012] The α-angle driving mechanism of the Luxembourg PW type furnace top distributor is composed of a pair of open gear pairs and a pair of worm gear pairs. It has a compact structure and stable performance, but it has high requirements for materials and processing technology, and the cost of spare parts and maintenance It is also extremely expensive. It is a type of equipment with good performance and high price. The cost performance is not high and it is not easy to promote

The invention discloses a double-cylinder yoke bell-less distributor for a blast furnace. The double-cylinder yoke bell-less distributing device comprises a distributor box body, a top cover, a water cooling disc, an upper rotation bearing, a rotary sleeve, a backing ring, a lower rotation bearing, a trunnion, a trunnion crank, a chute bracket, a chute, a throat pipe and a horizontal transmission device for controlling a beta angle of the chute. In the key improvement, the double-cylinder yoke bell-less distributor also comprises a backing ring driving mechanism; and the backing ring driving mechanism comprises a rigid driving arm, a rigid balance arm and a driving device for driving the rigid driving arm and the rigid balance arm to move up and down. The double-cylinder yoke bell-less distributor has the advantages that: due to the application of the two rigid yokes, the backing ring can be prevented from being tilted easily in all directions in the running process effectively, the mechanical linkage of two hydraulic cylinders is realized by utilizing the rigid yokes, and when abnormal conditions such as asynchronism and the like in the two hydraulic cylinders occur, the rigid yokes can protect the safety of the backing ring and downstream parts of the backing ring effectively under the allowable maximum load.
Description
technical field [0001] The invention relates to a blast furnace supporting equipment, in particular to a double-cylinder wishbone type blast furnace bellless distributor. Background technique [0002] The blast furnace chute distributor is the key equipment for blast furnace charging. Because of its flexible and uniform distribution characteristics, it has been widely used, and the flexible and stable movement of the chute is the key to the flexible and uniform distribution of the chute distributor. The position of the chute is controlled by its α angle and β angle relative to the axis of the distributor. The α angle is the angle between the chute and the axis of the distributor. One kind of movement is to change the angle between it and the axis of the distributor box, the purpose is to change the α angle of the chute, and the other is to drive the chute around the axis of the distributor by means of a driving device. The purpose is to change the β angle of the chute; the ...
