Abstract
The utility model relates to a rectangular gate comprising a framework, a flash board inserted into the framework and a drive device driving the flash board to move, wherein the framework is provided with a rectangular gate cavity therein, the closing motion of the flash board is forward, and sealing strips are arranged on the left and the right sides as well as at the rear end of the gate cavity and are in sealed match with the flash board. In the rectangular gate provided by the utility model, the sealing strips arranged on the left and the right sides as well as at the rear end of the gate cavity realize the sealing between the flash board and the gate cavity, thereby effectively avoiding leakage of raw coal and powdery materials.
Description
Technical field
The utility model relates to a kind of rectangular gate, particularly a kind of unidirectional manual spiral gate.
Background technique
Rectangular gate be used for to power plant's former coal bunker bottom raw coal every cutting, the ash tube, coal powder storehouse bottom powder sinking tube that also can be used for deduster and chimney bottom are every cutting a granular material.Chinese patent ZL2006200845691 discloses the pneumatic pumping board formula of a kind of coal bunker and has put coal gate, as shown in Figure 1, comprise bounce cylinder 1, main backstop 2, connecting frame 3, slip pumping board 4, connecting plate 5, cylinder piston rod 6, dovetail groove pulley 7, slideway 8 and riser 9, slip plate 4 is realized the keying in connecting frame 3 inner gate chambeies.Four angles are equipped with the dovetail groove pulley below the consistent size of the size of slip pumping board and connecting frame 3 outsides, angle steel support, and the dovetail groove pulley is stuck on the angle steel track.The above-mentioned coal gate of putting the problem that raw coal and granular material are revealed very easily occurs owing to do not have sealing configuration between gate chamber and slip pumping board.
The model utility content
The purpose of this utility model provides a kind of rectangular gate with sealing function, prevents that the problem that raw coal and granular material are revealed from taking place.
For achieving the above object, the utility model adopts following technological scheme: a kind of rectangular gate, comprise the flashboard of plug-in mounting in framework, the framework and the drive unit of driving ram movement, the gate chamber that has rectangle in the framework, the direction of flashboard closing motion is the place ahead, described gate chamber and arranged on left and right sides and rear end are provided with Stamping Steel Ribbon, and described Stamping Steel Ribbon and flashboard are sealed and matched.
Described gate chamber and arranged on left and right sides is respectively arranged with the Stamping Steel Ribbon mounting groove, the Stamping Steel Ribbon correspondence that is arranged at gate chamber and arranged on left and right sides is installed in the Stamping Steel Ribbon mounting groove, both sides at framework at least evenly are bolted with three jackscrews along the Stamping Steel Ribbon length direction respectively corresponding to the Stamping Steel Ribbon position, and cooperation is ended on the left side that described jackscrew is corresponding with Stamping Steel Ribbon or right flank top.
Described drive unit comprises the driving leading screw that the axially locating rotation is assemblied on the framework and axis extends along the ram movement direction, is bolted with nut on this driving leading screw, and described nut and flashboard are connected.
Sealing is coated with protecting jacket on the described driving leading screw.
Be provided with two row's axis support roller vertical with gate moving direction in the described gate chamber, described each support roller all cooperates with the flashboard jacking.
Described protecting jacket is a bellows.
Rectangular gate of the present utility model is provided with Stamping Steel Ribbon in gate chamber and arranged on left and right sides and rear end, and Stamping Steel Ribbon is realized the sealing between flashboard and the gate chamber, has effectively prevented the leakage of raw coal and granular material.
On framework, be bolted with the jackscrew that only cooperates with the Stamping Steel Ribbon top, control the sealing effect of Stamping Steel Ribbon and flashboard by the screw-in amount of adjusting jackscrew.Simultaneously, after wearing and tearing appear in Stamping Steel Ribbon, can strengthen the screw-in amount of jackscrew, Stamping Steel Ribbon is moved to the flashboard direction, be convenient to working service in the future.
The outside at leading screw installs bellows, and bellows can prevent that powder material from directly falling on the leading screw, prevents that abrasive wear from appearring in leading screw, has prolonged the working life of this rectangular gate.
