Abstract
The utility model provides a connecting rod type furnace door lifting mechanism, which comprises a furnace door, a connecting rod, a driving hydraulic cylinder and a support. The two sides of the furnace door are respectively connected with an upper connecting rod and a lower connecting rod which are parallel to each other in an up and down manner. One ends of the upper and lower connecting rods are connected with the furnace door respectively, while the other ends of the upper and lower connecting rods are connected with the support respectively. The lower connecting rod is also connected with the driving hydraulic cylinder. The furnace door can be lifted through the telescoping of the piston rod of the hydraulic cylinder. Since no lifting mechanism is arranged on the upper part of the furnace door, the height of the furnace door after being unlatched is greatly lowered. The connecting rod type furnace door lifting mechanism can be adapted to the reconstruction of old workshops and the lifting of the furnace doors of newly designed smelting furnaces and holding furnaces in aluminum and aluminum alloy industries and can also be adapted to melting furnace equipment in other industries. The connecting rod type furnace door lifting mechanism has the advantages of novel design, simple structure, strong practicability, low manufacturing cost, convenient usage and wide application prospect, which provides a simple and reliable lifting device for the lifting of furnaces doors.
Description
Technical field
The utility model provides a kind of link-type fire door elevating mechanism, relates in particular to aluminium and aluminium alloy industry and adopts fuel to melt the aluminium stove, leave standstill stove, holding furnace etc. as the flame of thermal source, belongs to metallurgical technology field.
Background technology
In the aluminium processing industry, along with the needs that development of technology and country eliminate the backward production facilities, domestic a lot of old brand aluminum fabrication plant is transformed through old workshop, upgrades large-scale advanced energy-saving equipment and replaces original mini-plant.Smelting furnace, holding furnace be as the first procedure equipment of aluminum fabrication plant, inevitably scrap build again, is in first-selected status in updating.At present; The founding design of workshop of a lot of aluminum fabrication plants is on the low side, when carrying out scrap build, when adopting the large-tonnage furnace installation; Be limited by the limitation in height of original factory building; When door opened height surpasses original workshop overhead traveling crane height, can cause the workshop overhead traveling crane to pass through, thereby have influence on the logistics in whole workshop.Traditional fire door hoisting way be hoisting mechanism be positioned at fire door directly over; Maximum height after the height of hoisting mechanism promotes greater than fire door; So just can not satisfy the requirement of on original factory building, building the Large Furnace subset; Therefore just must design a kind of novel fire door hoisting mechanism, to reduce the needs that height after door opened satisfies original factory building.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that prior art exists, and a kind of link-type fire door hoisting mechanism is provided, and the total height that reduces the fire door lifting is to satisfy the demand.
The purpose of the utility model realizes through following technical scheme: a kind of link-type fire door elevating mechanism; Comprise fire door, connecting rod, driving hydraulic cylinder and bearing; The both sides of fire door all are connected with last connecting rod and the lower link that laterally arranges up and down; One end of last connecting rod and lower link links to each other with fire door respectively, and the other end links to each other with bearing respectively; Lower link also links to each other with the driving hydraulic cylinder, drives the middle part that hydraulic cylinder is hinged on lower link.
Further, the no hoisting mechanism in described fire door top, the unlatching of whole fire door is by the Driven by Hydraulic Cylinder of fire door downside.
Further, described fire door compresses by deadweight or hydraulic cylinder puts in place compresses, and establishes hold-down mechanism no longer in addition.
Again further, described fire door both sides do not have the operation guide rail, and it is radius that fire door opens and closes with the connecting rod, move in a circle the stroke of the height decision hydraulic cylinder of fire door operation.
Substantive distinguishing features and obvious improvement that the utility model technical scheme is outstanding are mainly reflected in: the utility model is novel in design, simple for structure, practical; Be widely used in old workshop transformation project and newly-designed smelting furnace, the lifting of holding furnace fire door; Also be applicable on molten guarantor's furnace apparatus of other industry, for fire door provides a Simple and Reliable lifting device.This device low cost of manufacture, function brilliance, easy to use, application prospect is good.
Description of drawings
Below in conjunction with accompanying drawing the utility model technical scheme is described further:
Fig. 1: the structural representation of a kind of link-type fire door elevating mechanism of the utility model.
Label declaration among the figure: 1. fire door, 2. go up connecting rod, 3. lower link 4. drives hydraulic cylinder, 5. bearing.
The specific embodiment
The utility model provides a kind of link-type fire door elevating mechanism, relates in particular to aluminium and aluminium alloy industry and adopts fuel to melt the aluminium stove, leave standstill stove, holding furnace etc. as the flame of thermal source.
As shown in Figure 1; A kind of link-type fire door elevating mechanism, an end that mainly comprise last connecting rod 2 that fire door 1, fire door both sides laterally arrange up and down and lower link 3 these two connecting rods, drives hydraulic cylinder 4 and 5, two connecting rods of bearing is connected with fire door 1 respectively; An other end links to each other with bearing 5; Lower link 3 is hinged with driving hydraulic cylinder 4, is hinged on the following middle side part of lower link 2, and bearing 5 is connected with body of heater.
Fire door 1 top is not provided with hoisting mechanism, and the unlatching of whole fire door is by the Driven by Hydraulic Cylinder of fire door downside.And fire door 1 compresses by deadweight or hydraulic cylinder puts in place compresses, and establishes hold-down mechanism no longer in addition.The both sides of fire door 1 do not have the operation guide rail, and the keying of fire door 1 is a radius with the connecting rod, move in a circle the stroke of the height decision hydraulic cylinder of fire door 1 operation.
In sum, the utility model is novel in design, simple in structure, practical, is widely used on the smelting furnace, holding furnace of aluminium processing industry, also is applicable on the smelting furnace, holding furnace equipment of other industry.Can improve the automation of production operation greatly, ensure safety in production.This device low cost of manufacture, function brilliance, ease in use.
The foregoing description is technical conceive and the characteristics for the utility model is described just, its objective is to be the content that lets the one of ordinary skilled in the art can understand the utility model and to implement according to this, can not limit the protection domain of the utility model with this.The variation or the modification of every equivalence of having done according to the essence of the utility model content all should be encompassed in the protection domain of the utility model.
