Therefore, the fire door of a reliable operation of outfit has the important technology meaning concerning whole industrial furnace.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, a kind of furnace door lifting device is provided, be intended to improve the stationarity of fire door rise and fall action, thereby guarantee the fire door reliable operation.
Purpose of the present invention is achieved through the following technical solutions:
Furnace door lifting device, characteristics are: fix a crossbeam on the furnace roof steel construction, on crossbeam, be furnished with sprocket wheel, described sprocket wheel is bearing on the crossbeam by the connecting axle rotation freely, hang a chain fixed bar in the end of crossbeam, below the crossbeam between chain fixed bar and the crossbeam upper sprocket wheel, fix a hydraulic cylinder, the top of described hydraulic cylinder piston rod is equipped with sprocket wheel, be equipped with the chain that is meshed with it on the sprocket wheel of hydraulic cylinder piston rod and on the sprocket wheel of crossbeam, one end of chain is connected with the chain fixed bar, and the other end of chain is connected with fire door.
Further, above-mentioned furnace door lifting device, wherein, on crossbeam, be furnished with simple chainwheel successively, first duplex chain wheel and second duplex chain wheel, sprocket wheel on the hydraulic cylinder piston rod is a duplex chain wheel, duplex chain wheel on the hydraulic cylinder piston rod is between second duplex chain wheel on the crossbeam and chain fixed bar, simple chainwheel on crossbeam, first duplex chain wheel, be nested with first chain that is meshed with it on the duplex chain wheel of second duplex chain wheel and hydraulic cylinder piston rod, one end of first chain is connected with the chain fixed bar, and the other end of first chain is connected with a side of fire door; On the duplex chain wheel of first duplex chain wheel on the crossbeam, second duplex chain wheel and hydraulic cylinder piston rod, be nested with second chain that is meshed with it, one end of second chain is connected with the chain fixed bar, and the other end of second chain is connected with the opposite side of fire door.
Further, above-mentioned furnace door lifting device, wherein, described crossbeam is by being bolted on the furnace roof steel construction.
Again further, above-mentioned furnace door lifting device, wherein, the cylinder seat of described hydraulic cylinder is by being bolted on the crossbeam.
Substantive distinguishing features and obvious improvement that technical solution of the present invention is outstanding are mainly reflected in:
Modern design of the present invention, when fire door need rise or descend, hydraulic cylinder piston rod was released or is regained, and the sprocket wheel that drives its head descends or rising, rotates thereby drive driving-chain, and fire door is steadily risen or decline.Structure is very compact, has improved the functional reliability of fire door greatly, is the new design of a practicality.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Fig. 1: structural representation of the present invention.
The implication of each Reference numeral sees the following form among the figure:

The specific embodiment
As shown in Figure 1, furnace door lifting device, on the furnace roof steel construction, one crossbeam 7 is arranged by bolting, on crossbeam 7, be furnished with simple chainwheel 4 successively, first duplex chain wheel 6 and second duplex chain wheel 8, simple chainwheel 4, first duplex chain wheel 6 and second duplex chain wheel 8 are bearing on the crossbeam 7 freely by connecting axle 5 rotations respectively, hang a chain fixed bar 9 in the end of crossbeam 7, below the crossbeam between the chain fixed bar 9 and second duplex chain wheel 8, fix a hydraulic cylinder 10, the cylinder seat of hydraulic cylinder 10 is by being bolted on the crossbeam 7, the top of hydraulic cylinder piston rod is equipped with duplex chain wheel 11, and the duplex chain wheel 11 on the hydraulic cylinder piston rod is between on the crossbeam between second duplex chain wheel 8 and the chain fixed bar 9; On the duplex chain wheel 11 of the simple chainwheel on the crossbeam 4, first duplex chain wheel 6, second duplex chain wheel 8 and hydraulic cylinder piston rod, be nested with first chain 2 that is meshed with it, one end of first chain 2 is connected with chain fixed bar 9, and the other end of first chain 2 is connected with the left side of fire door 1; On the duplex chain wheel 11 of first duplex chain wheel 6, second duplex chain wheel 8 and hydraulic cylinder piston rod on the crossbeam, be nested with second chain 3 that is meshed with it, one end of second chain 3 is connected with chain fixed bar 9, and the other end of second chain 3 is connected with the right side of fire door 1.
During concrete work, when hydraulic cylinder piston rod stretched out, the duplex chain wheel 11 that drives on the piston rod was descending, makes first chain 2 and second chain, 3 tensioners, drove driving-chain and rotated, and slowly rose thereby drive fire door 1.During the hydraulic cylinder piston rod withdrawal, the duplex chain wheel 11 that drives on the piston rod is up, and first chain 2 and second chain 3 are loosened, and driving-chain rotates, and fire door 1 slowly descends under the gravity effect.Adopt the driving force of hydraulic cylinder, avoid the not steady phenomenon of operation in fire door lifting or the decline process as the fire door lifting.
In sum, modern design of the present invention, fire door is realized steadily rising or descending with the driving force of hydraulic cylinder, and member is organically combined by driving chain, has saved installing space; Compact conformation, stable action during the fire door rise and fall has fully guaranteed the functional reliability of fire door.
