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 single-cylinder fork-arm type non-bell blast furnace distributing device which comprises a distributing device body, a top cover, a water cold disk, an upper pivoting support, a rotating sleeve, a backing ring, a lower pivoting support, a trunnion, a trunnion crank, a chute bracket, a cute, a throat pipe and a horizontal transmission device for controlling the beta angle of the chute. The distributing device is characterized by also comprising a backing ring driving mechanism, wherein the backing ring driving mechanism comprises a rigid driving arm, a rigid balance arm and a driving device for driving the up and down movement of the rigid driving arm and the rigid balance arm. The distributing device in the invention has the advantages that the symmetric double-point driving of the non-radial component force of the back ring acted by a hydraulic cylinder is realized by using the shortest transmission chain; and the rigid driving arm evolves the single-point driving of the rigid driving arm acted by the hydraulic cylinder into the double-point driving of the backing ring acted by the rigid driving arm.
Description
technical field [0001] The invention relates to a blast furnace supporting equipment, in particular to a single cylinder fork arm 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 ...
