Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is the structural representation that the car bottom door of this device is opened rotating mechanism and car bottom door opening angle adjustable limiting mechanism.
As shown in the figure: 1 leading screw, 2 screws, 3 scales, 4 bearing seats, 5 centering blocks, 6 reservoirs, 7 imput shaft, 8 are crank throw, 9 drive connecting rod, 10 limited location forks, 11 slotted eyes, 12 casings, 13 risers, 14 driven crank throws, 15 driven shafts initiatively.
The specific embodiment
Contrast Fig. 1 is used step to be described further to operation of the present invention:
Control an inhibiting device for bottom door of railway hopper car opening angle, comprise car bottom door unlatching rotating mechanism, it is characterized in that: also comprise car bottom door opening angle adjustable limiting mechanism.Described car bottom door opening angle adjustable limiting mechanism comprises riser 13, casing 12 and leading screw 1, described riser 13 is positioned at casing 12 left sides, riser 13 is connected by base with casing 12 and is fixedly connected with carriage bottom plate, described leading screw 1 is through riser 13 and casing 12, between riser 13 and casing 12, be provided with the screw 2 supporting with leading screw 1, at leading screw 1 right-hand member, connect limited location fork 10, on the double-layer plate of described limited location fork 10, be respectively equipped with slotted eye 11.The scale 3 that is provided with 1 displacement of demonstration leading screw above of described casing 12, described screw 2 peripheries are provided with turning handle.Described car bottom door is opened rotating mechanism and is comprised imput shaft 7, centering block 5 and driver train; Described imput shaft 7 is passed the centre hole of centering block 5 and is fixedly connected with centering block 5, the two ends of described imput shaft 7 are fixedly connected with carriage bottom plate by bearing seat 4 respectively, in described centering block 5 upper ends, connect driver trains, described centering block 5 lower ends are between the double-layer plate of limited location fork 10 and hinged by being through the pin of 11 of slotted eyes; Described imput shaft 7 is connected with car bottom door bar-turning mechanism.The driver train that described car bottom door is opened rotating mechanism comprises reservoir 6, and described reservoir 6 is fixedly connected with compartment, and the piston rod of described reservoir 6 and centering block 5 upper ends are hinged.
The using method of the present embodiment: it can also be the structure that imput shaft 7 drives by motor and speed reducer that described car bottom door is opened rotating mechanism.Described car bottom door opening angle adjustable limiting mechanism can also be the tooth bar meshing with gear, adjusts the spacing of tooth bar end face and centering block 5 lower ends by arm revolving gear, car bottom door is opened to rotating mechanism and carry out spacing.
Because imput shaft 7 is passed the centre hole of centering block 5 and is fixedly connected with centering block 5, the deflection angle of centering block 5 has determined the rotational angle of imput shaft 7.One, rotate screw 2, by scale 3, record the scale of leading screw 1 displacement.Two, by the piston rod promotion centering block 5 upper ends deflection left of driver train reservoir 6, the limited location fork 10 on leading screw 1 the right has limited the actuation range of centering block 5 bottoms.Driver train can also be hydraulic ram.Three, described imput shaft 7 is connected with car bottom door bar-turning mechanism; Car bottom door bar-turning mechanism can be that imput shaft 7 is passed through initiatively crank throw 8, drive connecting rod 9, and driven crank throw 14 is connected with driven shaft 15; Initiatively the left end of crank throw 8 is fixedly connected with imput shaft 7, and the left end of driven crank throw 14 is fixedly connected with driven shaft 15, and the two ends of drive connecting rod 9 are hinged with the right-hand member of active crank throw 8 and the right-hand member of driven crank throw 14 respectively.On driven shaft 15, by crank throw and connecting rod, hopper wagon bottom door is installed.The rotational angle of imput shaft 7 has determined the rotational angle of driven shaft 15 and the opening angle of hopper wagon bottom door.Car bottom door bar-turning mechanism can also be the structure that imput shaft 7 is directly connected with driven shaft 15.Four, the deflection to the right of centering block 5 lower ends, rotates counterclockwise imput shaft 7 and drives driven shaft 15 to rotate counterclockwise, and hopper wagon bottom door is opened separated with compartment funnel skew wall, and the opening angle of bottom door is corresponding with the scale that scale 3 records leading screw 1 displacement.Four, the scale of original leading screw 1 displacement of recording with reference to scale 3, rotates screw 2 as required again, and the opening angle of capable of regulating hopper wagon bottom door, realizes unloading as required.
