Abstract
The utility model discloses an electrical rollover bow screen; a bow screen plate is fixedly arranged on a screen box, a screen box rotary shaft which is fixedly connected onto the bottom of the screen box is positioned in a shaft sleeve being capable of relatively rotating, the periphery of the shaft sleeve is fixedly provided with an inner side supporting lug and an outer side supporting lug, and the inner side supporting lug is hinged on a base; and the outer side of the upright post of the base is provided with a support, the position between the support and the outer side supporting lug is provided with a thread shaft, and the lower end of the thread shaft is connected with a multiple-rotary electric device. The utility model is capable of electrically rolling-over, and is stable in lifting and is accurate in lift travel control during the whole rolling-over process.
Description
Technical field:
The utility model relates to a kind of electric turnover sieve bend.
Background technology:
De-mediated, dehydration and desliming at coal separation system fine fraction coal slime, present normal a kind of upset sieve bend, be that arc screening plate is fixedly installed on the screen box, screen box is by upright supports, and under the duty, the screen box bottom surface is horizontal by 45 °～60 ° inclination angles, in order to satisfy the requirement of production technology, and the service life of improving screen cloth as far as possible,, after washing away after a while, screen cloth Rotate 180 in the plane at screen box place need be continued ° again to use at screen cloth.The method of operating of this rotary course is at first to use manpower at present, approximately need 8～15 people, screen box is turn to horizontal level together with arc screening plate from 45 °～60 ° heeling condition, screen box and arc screening plate could be carried out 180 ° rotation then, finish after the rotation, re-use manpower and with screen box and together with the arc screening plate reverse flip it is recovered on the user mode at 45 °～60 ° of inclination angles, the whole operation process was both dangerous, wasted time and energy again.
Summary of the invention:
For overcoming the defective of prior art, the purpose of this utility model is to provide a kind of electric turnover sieve bend, so that the switching process of sieve bend is easily quick, safe and reliable.
The utility model technical solution problem adopts following technical scheme:
The electric turnover sieve bend, arc screening plate is fixedly installed on the screen box, the screen box rotating shaft that connects firmly in screen box bottom is arranged in relatively turnable axle sleeve, is set with medial support ear and outside support ear in the periphery of axle sleeve, and described medial support ear is hinged on the support; The outside at the support column is provided with bearing, between described bearing and the described outside support ear thread spindle is set, and the lower end of described thread spindle is connected with many revolution electric devices.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the utility model makes the switching process of sieve bend easily quick, safe and reliable for the upset sieve bend is provided with electric driving mechanism.Drive the thread spindle rotation and lifting by many revolutions electric device (or electric pushrod), thus the control sieve bend rise and fall flat, make the sieve bend lifting steadily, the position angle precise control.
2, the utility model electric turnover, the course of work lifting of whole upset is steady, the lifting travel precise control.
3, the utlity model has the moment defencive function.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model screen box bottom pivot structure schematic diagram.
Number in the figure: 1 screen box, 2 thread spindles, more than 3 revolution electric devices, 4 bearings, 5 supports, 6 support columns, 7 discharging openings, 8 arc screening plates, 9 screen box rotating shafts, 10 axle sleeves, 11 medial support ears, 12 outside support ears.
Below pass through the specific embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.
The specific embodiment:
Embodiment: referring to Fig. 1, Fig. 2, according to existing version, arc screening plate 8 is fixedly installed on the screen box 1; In the present embodiment, the screen box rotating shaft 9 that connects firmly in screen box 1 bottom is arranged in relatively turnable axle sleeve 10, periphery at axle sleeve 10 is set with medial support ear 11 and outside support ear 12, medial support ear 11 is hinged on the support 5, the outside at support column 6, bearing 4 is set, between bearing 4 and outside support ear 12 thread spindle 2 is set, the lower end of thread spindle 2 is connected with many revolution electric devices 3.
When needs during with screen cloth Rotate 180 °, operation as follows:
1, starts many revolution electric devices 3, the top height of thread spindle 2 is reduced, screen box 1 is pulled to horizontal level;
2, rotation screen box 1 makes screen box rotating shaft 9 Rotate 180 ° in its sleeve 10; Symmetrically arranged two discharging openings 7 have also formed 180 ° location swap in the screen box 1;
3, start many revolution electric devices 3 once more, the top height of thread spindle 2 is raised again, up to screen box 1 is pushed back to former incident angle;
4, close many revolution electric devices 3, whole upset, rotary course finish.
