Description
Technical field
The present invention relates to a kind of speed variator type double system transmission that is used for blast furnace bellless furnace top distributing gear, belong to technical field of metallurgical equipment.
Background technology
Ferrous metallurgy technology and industry are that a country realizes industrialization, enters flourishing social basis, it also is the important symbol of an industrialization of the country degree, it also is an industry that the environment and the energy state of country are had material impact simultaneously, therefore, its state of development will have the most direct influence to country and people's quality of life.Blast furnace roof material distributing device is the visual plant of ferrous metallurgy technology; In the process of the blast-furnace smelting pig iron, need with the situation of atmospheric isolation under continuously furnace charge is added in the burner hearth, will reasonably be distributed on the charge level on request, just can form the shape of charge level that needs and furnace throat radially the burnt thickness in ore deposit (ore coke ratio) distribute; Therefore, the cloth Performance And Reliability to top filling equipment has proposed very high requirement; Early stage apparatus for distributing is all for there being the bell furnace roof, as two clock-types, three clock-types, four clocks and clock valve formula furnace roof, but have that sealing is unreliable, great bell weight big, the shape of cloth charge level is difficult to control, subject matter such as maintenance of equipment complexity, work-ing life are lacked.From the seventies in last century, no bell furnace roof has appearred, promptly adopt rotary distributor, this has brought new mode for blast furnace operating, very fast various places all over the world are from development trend, for large blast furnace, no bell furnace roof will be substituted with the bell furnace roof, occupy an important position in the ferrous metallurgy technology.
At present, the blast furnace bellless furnace top distributor that is adopted mainly contains following a few class, and principal character is:
(1) based on planetary dual motors system, main rotation and these two kinds of motions of fascinating all are to be undertaken synergeticly by sun and planet gear, have characteristics such as operate steadily, pivoted loop is stressed evenly, reliability is higher; Mechanism's more complicated, planetary stressed bigger, serious wear must use bi-motor to link, and the required driving power that fascinates is bigger, and it is bigger to consume energy.
(2) based on differential dual motors system, adopt bi-motor to drive the master respectively and rotate back to change and the pivoted loop that fascinates, differential realization the by two pivoted loops fascinated, differential control there is very high requirement, must use bi-motor to link, the required driving power that fascinates is bigger, and it is bigger to consume energy.
(3) based on the pivoted loop jacking system of lever, the up-and-down movement of the pivoted loop that fascinates can be adopted electric motor driving, or adopts hydraulic efficiency system to realize, but needs synchronous device or Controlling System to work in coordination with the up-and-down movement that presses down pivoted loop; Because the restriction of the vertical space of distributor, the stroke of lever vertical movement is very limited, so lever is stressed bigger, and the contact wear between lever and the pivoted loop is serious, moves not steady; Need adopt double dynamical (bi-motor) system during operation, required driving power is bigger, and it is bigger to consume energy.
Studying blast furnace bellless furnace top distributing gear efficient, energy-conservation, that reliability is high is a present important research direction.
