Background technology
At metallurgy industry, sintering plant adopts strand exhaust sintering machine to produce sintering deposit conventionally, and sintering machine body mainly comprises transmission device, chassis, vacuum tank, sealing device.Pallet from bottom to top moves, and in the time that chassis runs to below, down, under self gravitation effect, the fire grate bar on chassis has the trend that lets droop to chassis working face; When chassis runs to top, its working face upward, but middle part part cannot reset because of the fire grate bar that damage hangs, exceed chassis working face, even if adopt grate-layer material technique, also do not reach the object of protection fire grate, make bed permeability poor, increase load of dust remove, affect the fan rotor life-span, be unfavorable for reducing or eliminating fire grate sizing; The fire grate bar exceeding is also unfavorable for the safe operation of chassis; If the fire grate bar that exceeds working face is not resetted, will directly affect the quality of production and the efficiency of sintering deposit, and have potential safety hazard.
Application number is 201110210797.4 Chinese invention patent, a kind of grate bar pressing device for sintering machine trolley is disclosed, this design compresses grate bar at trolley board of sintering machine inner side welding steel briquetting, effectively prevented that car type furnace grid section two ends from coming off and becoming flexible, but the fire grate bar that the damage of chassis middle part is hung does not have reset response.
Summary of the invention
The purpose of this utility model is exactly to overcome the defect that prior art exists, and provides one can make fire grate bar reset in time, effectively improves the pallet fire grate bar resetting means of the quality of production and the efficiency of sintering deposit.
For achieving the above object, the pallet fire grate bar resetting means that the utility model is designed, its special character is: it comprises and is suspended at pallet top, the pressure roller parallel with fire grate bar length direction, the two ends of described pressure roller are separately fixed at one end of two brace summers, the other end of described two brace summers respectively by bearing pin with to be arranged on two holders on pallet dust cover one side girder hinged; On described pallet dust cover opposite side girder, be provided with rings seat, the position of the corresponding rings seat of described brace summer is provided with suspension ring, and described suspension ring are connected with rings seat by steel wire rope.
Further, between described two brace summers, be provided with tube connector, described tube connector is connected and fixed by the pullover and brace summer at two ends.Like this, can make the spacing of two brace summers remain unchanged, and then ensure rotating freely of end pressure roller.
Further, described pressure roller two ends are provided with roll shaft, and described roll shaft outer end is by being fixed on one end of two brace summers with the roller bearing units of square base.Like this, can be so that the installation of pressure roller and replacing.
Further, described roll shaft is located by axial taper sheath tensioner with the roller bearing units with square base.Like this, can be so that the centering location of pressure roller roll shaft prevents bias.
The utility model has the advantage of: designed pallet fire grate bar resetting means, can in the running of pallet, carry out in real time fire grate bar reset, the sinter quality and the low inferior problem of production efficiency that cause because of fire grate bar out-of-flatness are avoided, also protected fire grate simultaneously, reduce load of dust remove, extend the fan rotor life-span, reduce or eliminate fire grate sizing; Be conducive to the safe operation of chassis, reduce safety in production hidden danger.

Fig. 2 is the left TV structure schematic diagram of Fig. 1.
Fig. 3 is the A-A cross-sectional view in Fig. 1.
In figure: pallet 1; Pressure roller 2; Brace summer 3; Bearing pin 4; Girder 5; Holder 6; Roll shaft 7; Rings seat 8; Suspension ring 9; Steel wire rope 10; Tube connector 11; Pullover 12; Roller bearing units 13 with square base; Flange 14.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Pallet fire grate bar resetting means shown in figure, it comprises and is suspended at pallet 1 top, the pressure roller 2 parallel with fire grate bar length direction, pressure roller 2 is fixed on one end of two brace summers 3, and the roll shaft 7 at its two ends is fixed between two brace summers 3 by the roller bearing units 13 with square base; The roll shaft 7 at pressure roller 2 two ends and the roller bearing units 13 with square base are located by axial taper sheath tensioner.The other end of two brace summers 3 respectively by bearing pin 4 with to be arranged on two holders 6 on pallet dust cover one side girder 5 hinged; On pallet dust cover opposite side girder 5, be provided with rings seat 8, the position of the corresponding rings seat 8 of brace summer 3 is provided with suspension ring 9, and suspension ring 9 are connected with rings seat 8 by steel wire rope 10.
For two spacing between brace summer 3 are remained unchanged, between two brace summers 3, be provided with tube connector 11, the through hole of offering on two brace summers 3 is passed respectively at tube connector 11 two ends, and on tube connector 11 two ends outer tube walls, is equipped with the flange 14 of two brace summer 3 madial walls of butt; Tube connector 11 two ends are also provided with pullover 12, pullover 12 and are connected and fixed by bolt and tube connector 11 terminations, and tube connector 11 is connected location with pullover 12 cooperation with brace summer 3 by flange 14.
