Description
Technical field
The utility model relates to a kind of oblique pull headstock gear adaptive sliding wheel system.Be applicable to water power hydraulic engineering and similar field.
Background technology
Headstock gear normal design operating mode for work vertically, but in water power hydraulic engineering, sometimes for reducing civilwork engineering quantity, can arrange the gate of oblique keying.The opening and closing device of oblique open-close sluice gate is oblique pull headstock gear, and when gate is in gate slot, oblique pull headstock gear is the oblique pull operation operating mode of certain angle, but is again vertical operation operating mode after gate goes out gate slot.For oblique pull headstock gear pulley system, because the wire rope between fixed pulley to movable pulley can have certain pendulum angle in oblique pull with vertical drawing in change working process, if pulley system designs routinely, fixed pulley beam is oblique eccentric force state, and the interference and the wire rope that are difficult to solution wire rope and fixed pulley beam pass in and out the excessive problem of pulley angle simultaneously.
Summary of the invention
The technical problems to be solved in the utility model is: for above-mentioned Problems existing, a kind of oblique pull headstock gear adaptive sliding wheel system is provided, make fixed pulley and fixed pulley beam automatically can adapt to movable pulley at oblique pull and the vertical pendulum angle drawn in change working process, the interference and the wire rope that solve wire rope and fixed pulley beam pass in and out the excessive problem of pulley angle; Meanwhile, make fixed pulley beam all be in center stressed state under any operating mode, improve the security of operation degree of equipment and the application life of wire rope.
The technical scheme that the utility model adopts is: a kind of oblique pull headstock gear adaptive sliding wheel system, the wire rope that there is fixed pulley, movable pulley device and be wrapped between fixed and moving pulley, two of wire rope be entangled to respectively be fixed on pulley system both sides reel on, it is characterized in that: described fixed pulley is arranged on the bottom of movable fixed pulley beam, this movable fixed pulley beam is installed in rotation on fixed pulley beam hinged bearing device, and the rotation direction of movable fixed pulley beam is consistent with the incline direction under headstock gear oblique pull operating mode.
Described fixed pulley beam hinged bearing device is made up of support, bearing and bearing support and axle, and described support and headstock gear frame are fixed, and bearing and bearing support are arranged between two side stands by axle is rotating, and described movable fixed pulley beam is loaded on bearing and bearing support top.
The hunting range of described movable fixed pulley beam is 0 ~ 45 °.
The beneficial effects of the utility model are: the utility model for oblique pull headstock gear can reduce headstock gear Hoisting System layout size, improve fixed pulley beam stress thus optimize fixed pulley beam structure, avoid the excessive problem of wire rope turnover pulley angle thus improve application life of wire rope, improve the safety in operation of equipment, there is certain technology, economy and social benefit.

Detailed description of the invention
As shown in Figure 1, Figure 2, Figure 3 shows, the wire rope 5 that the present embodiment has fixed pulley 4, movable pulley device 6 and is wrapped between fixed and moving pulley, two of wire rope is entangled to respectively to be fixed on the reel 1 on pulley system both sides, and wire rope 5 from reel on one side out, be entangled to the reel of another side after penetrating movable pulley device 6, fixed pulley 4, form a closed loop steel cable winding system.Fixed pulley 4 is arranged on the bottom of movable fixed pulley beam 3, and movable fixed pulley beam 3 is installed in rotation on fixed pulley beam hinged bearing device 2, and the rotation direction of movable fixed pulley beam 3 is consistent with the incline direction under headstock gear oblique pull operating mode.Fixed pulley beam hinged bearing device 2 is made up of support 2-1, bearing and bearing support 2-2 and axle 2-3, and support 2-1 and headstock gear frame are fixed, and bearing and bearing support 2-2 are arranged between two side stands by axle 2-3 and also can rotate around X-X axis.In this rotation (swing) mechanism, certain spacing should be left bottom bearing and bearing support 2-2 with bottom support 2-1, rotation just can be made to be achieved.Movable fixed pulley beam 3 is fixed on bearing and bearing support 2-2 top also can with its unitary rotation, and the design slewing area of movable fixed pulley beam 3 can reach 0 ~ 45 °.
Operating principle of the present utility model is: vertically drawing under operating mode, and as shown in Figure 1, fixed pulley 4 and movable pulley device 6 are in a vertical line, and movable fixed pulley beam 3 is in vertical position and be in center stressed state.Under oblique pull operating mode, as shown in Figure 2, movable fixed pulley beam 3 and fixed pulley 4 can adaptive rotations around fixed pulley beam hinged bearing device 2 under lineoutofservice signal pull effect, its rotational angle α is consistent with headstock gear oblique pull angle, and (the oblique pull angle of oblique pull door machine is generally within 10 °, and the theoretical rotational angle α of movable fixed pulley beam 3 can reach 45 °), make fixed pulley 4 and movable pulley device 6 all the time in a straight line.
This automatic adaptive capacity can make movable fixed pulley beam 3 be in center stressed state all the time, thus the angle making wire rope 5 pass in and out pulley can not increase along with the oblique pull of headstock gear, make the gap be entangled between the wire rope 5 of reel and movable fixed pulley beam 3 substantially remain on definite value state simultaneously.
