Embodiment Construction

[0026] There are many ways to use digital cylinders on the blast furnace distributor. The main methods are single digital cylinder method, two digital cylinder method and three digital cylinder methods.

[0027] 1. The method of using three digital cylinders is exactly the same as that of ordinary cylinders, such as figure 1 As shown, the reference numeral 1 is a digital cylinder, 2 is a horizontal rotation detection device, 3 is a connecting rod, 4 is a support ring, 5 is a lower slewing bearing, 6 is a connecting piece, 7 is a connecting shaft, 8 is a frame, 9 10 is the box, 11 is the water cooling plate, 12 is the chute, 13 is the water cooling steel ring, 14 is the rotating sleeve, 15 is the throat, 16 is the upper slewing bearing, 17 is the top cover, 18 is the horizontal rotation drive device. exist figure 1 Among them, the three digital cylinders 1 are installed on the top cover of the distributor with the flange at the front end in a 120° central symmetry form, and t...

Abstract

The present invention relates to a blast furnace chute distributor that controls the obliquity of the rotating chute via the resultant motion of rotation and rectilinear motion for the advisable distribution on the burden surface. This blast furnace chute distributor mainly contains: box body, top cover, hollow throat, upper slewing ring, turning sleeve, trunnion, crank, crank tail drum, chute bracket, chute, frame, lower slewing ring, support ring, guide rail, drive device of horizontal rotation, digital servo cylinder. One or three digital servo cylinders are combined with the steel wire rope, pulleys, parallel ruler, lever and guide rail to realize the vertical translation of the support ring controlling the chute obliquity. Via the blast furnace chute distributor driven by the digital servo cylinders, the structure is simplified and the accuracy is enhanced. The effect is similar with transmission by steel wire ropes but the setting and debugging are much more convenient.

Description

technical field [0001] The invention relates to a blast furnace chute distributor, in particular to a blast furnace chute distributor driven by a digital hydraulic cylinder (digital cylinder for short). Background technique [0002] At present, there are two main types of bellless top equipment for blast furnaces. The first type is the distributor of the traditional planetary differential transmission system. It is called PW type distributor; the second type is the distributor of "synthetic motion of rotation and linear motion", such as the CN85109284A patent of the inventor Seng Quansong et al.: hydraulic transmission distribution device, this distributor is called Seng's blast furnace distribution device device. [0003] The driving and transmission modes of Seng's blast furnace distributor are as follows: [0004] 1. It is a hydraulically driven distributor, such as the patent CN85109284A, which is characterized in that three cylinders are connected in parallel to move...
