Embodiment Construction
[0019] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0020] Such as figure 2 , 3 As shown, the blast furnace large-scale pre-block feeding device of the present invention includes a device frame 4, and the front end of the device frame 4 is provided with two travel motors 2, and a grooved wheel 6 is rigidly fixed on each motor shaft, and the rear end of the device frame 4 Two grooved wheels 6 are arranged on the same line as the wheels on the same side of the motor shaft. The hoist 1 and the fixed pulley 5 are arranged on the device frame 4. The position of the drum of the hoist 1 is opposite to the fixed pulley 5. The wire rope on the hoist 1 passes through the fixed pulley. Pulley 5 is connected with single-line high-speed hook 3, and one end of the wire rope linked by single-line high-speed hook is connected with winch, and the other end is fixed on the device frame. The hoist and stroke motor are controlled by a...

The invention discloses a blast furnace large pre-building block furnace feeding device and a method. The device comprises a device frame, the front end of which is provided with two stroke motors. Each motor shaft is rigidly fixed with a grooved wheel. The rear end of the device frame is provided with two grooved wheels, which are on same lines with the wheels of same sides on the motor shafts. The device frame is equipped with a hoisting machine and a fixed pulley. The position of a hoisting machine winding cylinder is towards the fixed pulley. The steel wire rope on the hoisting machine is connected to a single-line high-speed hook head through the fixed pulley. The grooved wheels are disposed on a track, below which a track stand is arranged. The props and sides of the track stand are equipped with cable-stayed supports. A track slip line is fixed at two ends of a track stand side. By means of the blast furnace large pre-building block furnace feeding device and the method provided in the invention, the pre-building block can be hoisted from a blast furnace casting house platform to a furnace top access door platform and is hanged at the furnace bottom in one time, thus effectively overcoming the problems of pre-building block furnace feeding, and reducing the use of manpower and machinery, saving time, and fully guaranteeing the furnace bottom masonry material supply.
Description
technical field [0001] The invention relates to the metallurgical industry, in particular to a large-scale pre-block feeding device and method for a blast furnace. Background technique [0002] In recent years, some large-scale blast furnaces have introduced large-scale prefabricated block structures such as Riel ceramic cups or German SGL carbon bricks. Due to the large volume, heavy weight, and specific shape of the prefabricated blocks, material transportation and hoisting are difficult, especially the size of the iron port and tuyere is small. , Some prefabricated blocks cannot enter the furnace from the iron port and tuyere, and the feeding of materials into the furnace is a difficult problem in construction. Traditionally, cranes or crown cranes are often used to hoist large prefabricated blocks to the inspection door platform on the top of the furnace, then monorail electric hoists are used to hoist the prefabricated blocks to the furnace throat protection shed, and h...
