Description

A kind of lifting device of spiral classifier
Technical field
The utility model belongs to the mine mechanism field, relates in particular to a kind of lifting device of spiral classifier.
Background technology
The lifting device of existing spiral classifier adopts worm reduction gear to slow down, wire rope pulley supports, connect by steel wire rope and the total journey youngster that hangs oneself, after the power set motor start-up, motor wheel drives worm reduction gear high speed shaft belt pulley by the V-belt and rotates, and worm reduction gear slow-speed shaft, wire rope pulley rotate simultaneously, and one, steel wire rope is fixed on wire rope pulley, steel wire rope drives the total Cheng Shangsheng of spiral, decline, completes lifting and the decline of the total journey of spiral classifier spiral.
Existing lifting device exists worm reduction gear not to be durable, and needs often to change, and causes production cost high, the little frangibility of the diameter of steel wire rope, the diameter conference of steel wire rope cause on wire rope pulley easily around irregular, and be unstable during lifting, time between overhauls(TBO) is frequent, and impact is normally produced.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of lifting device of spiral classifier, and its service life is longer, and is economical and practical.
For solving the problems of the technologies described above, the utility model provides a kind of lifting device of spiral classifier, and this lifting device comprises reduction box 9, screw 3 and leading screw 4;
Reduction box comprises casing 1, bevel gear 6 and bevel gear 2; Bevel gear 6 is arranged on an end of the power transmission shaft 8 that gos deep into casing 1, and the other end of power transmission shaft 8 is rotationally connected by bearing and casing 1 and stretches out casing 1; The end that power transmission shaft 8 stretches out casing 1 is connected with power set; Bevel gear 2 and bevel gear 6 engagements, bevel gear 6 is vertical with the axis of bevel gear 2; Screw 3 is sleeved on leading screw 4 and with bevel gear 2 and is fixedly connected with.
Optionally, screw 3 is fixedly connected with bevel gear 2 by bolt 5.
Compared with prior art, the utility model is provided with reduction box, screw and leading screw; Global design is simple for structure, and reduction box is higher than worm reduction gear intensity, and long service life is practical; Screw and lead screw transmission are steady, durable, can normally produce by assurance equipment Decrease production cost.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of lifting device of spiral classifier, this lifting device comprise reduction box 9, screw 3 and leading screw 4; Reduction box comprises casing 1, bevel gear 6 and bevel gear 2; Bevel gear 6 is arranged on an end of the power transmission shaft 8 that gos deep into casing 1, and the other end of power transmission shaft 8 is rotationally connected by bearing and casing 1 and stretches out casing 1; The end that power transmission shaft 8 stretches out casing 1 is connected with power set; Bevel gear 2 and bevel gear 6 engagements, bevel gear 6 is vertical with the axis of bevel gear 2; Screw 3 is sleeved on leading screw 4 and with bevel gear 2 and is fixedly connected with.
Reduction box 9 is casting pig reduction boxes, provide the power set of power to comprise motor, V-belt and belt pulley 7 to reduction box, belt pulley 7 is fixedly mounted on the outer end of casing 1 that power transmission shaft 8 stretches out reduction box 9, belt pulley 7 is connected with motor by the V-belt, be arranged on bevel gear 6 and bevel gear 2 engagements on power transmission shaft 8, screw 3 is fixedly connected with bevel gear 2 by bolt 5, and bevel gear 2 drives screw 3 rotations, and screw 3 drives leading screw 4 and rotarily drives the total Cheng Shangsheng of spiral or decline.
The utility model is provided with reduction box, screw and leading screw, and casting pig reduction box intensity has reduced the device damage probability greater than worm reduction gear, and is economical and practical, and screw and lead screw transmission are steady, have reduced the maintenance of equipment expense.
The above is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
