For achieving the above object, the utility model provides following technological scheme: what a kind of blade was adjustable holds cylinder, comprise cylinder body, the outer surface circumference of described cylinder body is evenly equipped with stator blade bearing, is provided with stator blade axle in described stator blade bearing, and described stator blade axle is provided with stator blade, also slipping block is installed with between described stator blade axle and stator blade, described stator blade axle is connected with stator blade through slipping block, and the gap between described slipping block and stator blade is fixed as 1.5mm, and described slipping block and cylinder body radially slippage are connected.
By adopting technique scheme, a part for cylinder body can be regarded as when slipping block slides on cylinder body, and the gap between described slipping block and stator blade is fixed as 1.5mm, solve stator blade and hold the gap adjustment problem between cylinder, and can by the slip of slipping block on cylinder body, the gap between stator blade and rotor can be regulated easily, the relative position that the stator blade solved easily in the stationary blade casing in TRT equipment holds cylinder and main shaft is relatively difficult to the problem regulated, and effectively raises the working efficiency of main axis.
The utility model is set to further: described cylinder body is provided with the chute matched with described slipping block, and described chute is arranged along the radial direction of holding cylinder, and described slipping block slippage is connected in described chute.
By adopting technique scheme, by cooperatively interacting of chute and slipping block, achieving the slippage of slipping block and the function led, by the mode of chute and slipping block, achieving the effect of the slippage on cylinder body of slipping block easily.
The utility model is set to further: be provided with guide collar above described stator blade axle, and described guide collar is connected by the other end of slidercrank mechanism stator blade relative to slipping block.
By adopting technique scheme, the guide collar arranged above stator blade axle, the rotation of guide collar can be converted into the rotation of stator blade by slidercrank mechanism, make quiet also established angle can open large or turn down, thus by the direction that gas channeling can drive movable vane to rotate by variable stator vane angle, the speed that movable vane rotates under the driving of blast furnace gas also can be controlled.
The utility model is set to further: described slidercrank mechanism is provided with the adjusting portion moved up and down that can regulate stator blade axle, described adjusting portion comprises adjustment screw and adjusting screw rod suitable with it, described adjustment screw is arranged on the port of the other end of stator blade axle Relative sliding block, on the crank that described adjusting screw rod is located at slidercrank mechanism and relatively one end of stator blade axle, described adjusting screw rod is flexibly connected with the crank of slidercrank mechanism is circumferential.
By adopting technique scheme, because adjusting screw rod is flexibly connected with the crank circumference of slidercrank mechanism, rotatable adjusting screw rod just can easily with the motion of moving-stator blade axle, owing to being provided with slipping block between stator blade axle and stator blade, and slipping block is spacing in chute, thus when adjusting screw rod rotates, with the radial slippage of moving-stator blade, the relative position between stator blade relative rotor can be regulated easily.
Compared with prior art, the utility model has the advantage of: the stator blade relative gap relatively held between cylinder can keep stable, need not realize by regulating stator blade, and gap between stator blade and rotor also can by regulating and controlling easily, the relative position that the stator blade solved in the stationary blade casing in TRT equipment holds cylinder and main shaft is relatively difficult to the problem regulated.
