Abstract
The utility model discloses a labor-saving device of a vertical roller mill. The labor-saving device makes a change in the prior structure, uses less pulling force of a fluid cylinder to generate more roller compaction force, and comprises a grinding roller which is connected with an upper rocker arm used as a rocker arm device of a lever. The rocker arm device is provided with an elongated lower rocker arm, one end of the elongated lower rocker arm is articulated with the fluid cylinder, and the other end is articulated with the top end of a heightened stand, and meanwhile, the rocker arm device is also connected with the stand.
Description
Technical field
The utility model relates to the vertical roll grinder work-saving device that cement industry large-scale vertical roller mill is used.
Background technology
As everyone knows, vertical roller grinder is passed to grinding roller with rocker arrangement with the hydraulic cylinder pulling force, realizes grinding roller rolling and grinding material.At present both at home and abroad used is mostly a kind of effort mechanism, promptly the hydraulic cylinder pulling force diminishes after the rocking arm transmission on the contrary, is unfavorable for producing big grinding pressure.Want to produce enough big grinding pressure like this and must will certainly increase cost with the hydraulic system that produces bigger power.
Summary of the invention
The purpose of this utility model in order to remedy the deficiencies in the prior art, has been done change exactly in existing mechanism, a kind of vertical roll grinder work-saving device is provided, and it can produce bigger grinding pressure with less hydraulic cylinder pulling force.
For achieving the above object, the utility model adopts following technical scheme:
A kind of vertical roll grinder work-saving device, it comprises grinding roller, grinding roller is connected with upper rocker arm as the rocker arrangement of lever, described rocker arrangement has the lower shake-changing arm of a lengthening, its end and hydraulic cylinder are hinged, and the hydraulic cylinder other end is hinged with the frame top of increasing, and rocker arrangement also is connected with frame simultaneously.
Described rocker arrangement is installed on the frame by bearing block, and the lower shake-changing arm upper end links to each other with upper rocker arm by axle, bearing, taper pin, and the lower shake-changing arm end is provided with bearing pin, and hydraulic cylinder links together the installing hole on bearing pin and the frame.
Effort-saving mechanism of the present utility model comprises that mainly grinding roller, rocker arrangement, hydraulic cylinder, support four parts constitute.Rocker arrangement is by upper rocker arm, lower shake-changing arm, axle, bearing block, taper pin, compositions such as bearing pin.Hydraulic cylinder one end is fixed on the support, and the other end links to each other with lower shake-changing arm, and lower shake-changing arm links to each other with upper rocker arm by axle, taper pin, and grinding roller is installed in the upper rocker arm.Rocker arrangement is similar to lever, and the hydraulic cylinder pulling force is passed to grinding roller.It mainly improves and is to have improved the lower shake-changing arm structure, has increased lower shake-changing arm lower end length, has increased hydraulic cylinder lower end impetus, makes the application of force arm of force greater than the stressed arm of force in grinding roller place.According to lever principle, just can produce bigger grinding pressure with less hydraulic cylinder pulling force.So just can select small-sized hydraulic cylinder for use.
The beneficial effects of the utility model are: produce same enough grinding pressures, select for use small-sized hydraulic cylinder and oil station both can, reduced cost.
Description of drawings
Fig. 1 is the installation diagram of grinding roller, rocker arrangement, hydraulic cylinder and frame before improving;
Fig. 2 improves the installation diagram of back grinding roller, rocker arrangement, hydraulic cylinder and frame;
Fig. 3 rocker arrangement side view;
Fig. 4 rocker arrangement partial sectional view.
Wherein, 1-frame, 2-hydraulic cylinder, 3-grinding roller, 4-rocker arrangement, 5-lower shake-changing arm, 6-upper rocker arm, 7-bearing block, 8-axle, 9-taper pin, 10-bearing, 11-bearing pin.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Among Fig. 1, Fig. 2, Fig. 3, Fig. 4, rocker arrangement 4 is installed on the frame 1 by bearing block 7, with hydraulic cylinder 2 installing hole on bearing pin 11 and the frame 1 is connected one.Grinding roller 3 is installed in the upper rocker arm 6.Lower shake-changing arm 5 upper ends link to each other with upper rocker arm 6 by axle 8, bearing 10, taper pin 9.So application of force arm of force L2 before improving＜stressed arm of force L1 is hydraulic cylinder 2 pulling force (application of force) F2〉grinding pressure (grinding roller is stressed) F1, the mechanism of this moment is effort mechanism.If keep grinding pressure F1 and stressed arm of force L1 constant, by height (promptly increasing L3) that increases hydraulic cylinder 2 lower end installing holes and the lower end length (lengthening L2) that increases lower shake-changing arm 5, can make L2〉L1, F2＜F1 like this, the mechanism of this moment is an effort-saving mechanism, and F2 obviously diminishes.So can select less hydraulic cylinder 2 for use.Select less hydraulic cylinder 2 for use, then provide the oil station of oil pressure also can reduce accordingly, provide cost savings.
