Abstract
The utility model relates to an improved double-drum lifter. When the utility model is used for a vertical (upright) well, both ends of two rolling drums of the utility model are respectively wound with a steel rope of an overlay rope and the steel rope of an underlay rope; other ends of the two steel ropes which are wound in the same direction are respectively connected with two lifting devices or a balancing bell, and four guide wheels are correspondingly collocated on a headframe. A guide wheel is additionally arranged on the headframe; both ends of the steel rope which is flexibly lapped on the guide wheel are respectively connected with two lifting containers (or the balancing bell) to reduce the maximum static tension of the steel rope of the lifter, and thus three-rope type multi-rope lifting is formed. Consequently, the pattern selection of the lifter can be lower with one to two stages, corresponding investment of well building and operation cost are reduced, and lifting work is safe.
Description
The utility model relates to mine hoist equipment, mainly is can only make the single-rope hoisting mode at double-drum hoist to change the multi rope winding mode into, is used for promoting or transfer weight at perpendicular (standing) well.
Mine hoist equipment is the visual plant of mining industry.Mainly undertaking the vertical transport task, is the key link of mining industry transportation.Both at home and abroad in perpendicular (standing) well promotes, the equipment that generally uses has two big classes at present: one makes single-rope hoisting as double-drum hoist; One makes multi rope winding for multi-rope friction hoisting machine.And the latter is used for deep-well more and be the mine of big-and-middle-sized scale.The twin-roll lifting means mainly consists of the following components: the other end that the coaxial cylinder that two quilts drive simultaneously, two head rolls respectively twine a steel cable (winding direction is opposite), two steel cables be connected with lifting container respectively (twin containers lifting), or one be connected with lifting container, and another root is connected (single container band counterweigght winding) with bob-weight and two steel cables need respectively dispose a track adjusting wheel on derrick.Double-drum hoist is pressed the classification typing of productive capacity size at present.Select the main foundation of lifting means, the one, it is poor to satisfy biggest quiet tension and biggest quiet tension that steel cable bears; The one, cylinder holds the needs that the rope amount must satisfy hoisting depth (especially when perpendicular (standing) well lifting personnel, require winding of single layer particularly outstanding).
Main purpose of the present utility model is: the first, can only change into the multi rope winding mode to double-drum hoist as single-rope hoisting, because steel cable is thinner, the Rong Shengliang that makes the cylinder winding of single layer increases and has improved the service hoisting depth of winding of single layer, and makes it have the advantage of multi rope winding; The second, effectively reduce the steel cable biggest quiet tension that gig bears.In a word, make gig type selecting " degradation " (promptly need select φ 3.5m for use and can select φ 3.0m for use even select φ 2.5m gig for use) as far as possible, reach the minimizing annual running cost of reducing investment outlay by traditional design.
The utility model proposes in perpendicular (standing) well, using double-drum hoist (seeing Fig. 1 and Fig. 2), is by two coaxial drive cylinders (1), a thinner underlap steel cable (6) and a thinner overlap steel cable (5) that two coaxial drive cylinders (1) twine respectively, the other end of two underlap steel cables (6) connects a lifting container (8), two overlap steel cables (5) other end connects a lifting container or a bob-weight (9), two underlap steel cables (6) required two less track adjusting wheels (3) on derrick, two overlap steel cables (5) required two less track adjusting wheels (2) on derrick.Here two track adjusting wheels (3) and two track adjusting wheels (2) are staggeredly arranged for double-layer horizontal, its horizontal separation distance equals the width between centers of lifting container (8) and lifting container or bob-weight (9), and promotes central lines on the line of centres and extended line thereof of lifting container (8) and lifting container or bob-weight (9).With regard to having formed two lifting containers or a lifting container and a bob-weight, the container amount of cylinder winding of single layer is increased (promptly increasing the hoisting depth of service) like this by the two rope formula multi rope windings that two thinner steel cables are suspending in midair.
Promote the steel cable biggest quiet tension in order to reduce, set up the 5th track adjusting wheel (4) on the derrick, steel cable (7) one ends that ride on the 5th track adjusting wheel (4) of living are connected with lifting container (8), the other end is connected with lifting container or bob-weight (9).The 5th track adjusting wheel (4) is arranged on the position, middle, below of two track adjusting wheels (2), track adjusting wheel (4) diameter should equal the width between centers of lifting container (8) and lifting container or bob-weight (9), the two ends of steel cable (7) are connected with lifting container or bob-weight (9) with lifting container (8) respectively, and its position is respectively in the middle of two steel cables (6) and two steel cables (5).Two lifting containers or a lifting container and the three rope formula multi rope windings that bob-weight is suspending in midair by 3 steel cables have been formed so again.
The utility model advantage is:
(1) the utility model is applicable to that all perpendicular (standing) wells promote applied range:
(2) the utility model makes it change the multi rope winding mode into by single-rope hoisting to the collocation form change that double-drum hoist promotes, and has not only improved the degree of safety that promotes, and has increased the service hoisting depth of steel cable winding of single layer;
(3) the utility model is set up the 5th track adjusting wheel and the 5th steel cable on derrick, has reduced the steel cable biggest quiet tension that acts on the gig effectively;
(4) the utility model improves the derrick strained condition, simplifies perpendicular (standing) well safety facilities;
(5) the utility model is brought into play the ability of gig fully, reach gig type selecting " degradation " effectively, correspondingly save electric power and reduced winding houses maintenance crane specification, receive and save shaft building and equipment investment, reduce the economic benefit of annual running cost.
Fig. 1 looks scheme drawing for the utility model master.
Fig. 2 is the utility model schematic top plan view.
Be indefiniteness embodiment (seeing 1 figure and Fig. 2) below, double-drum hoist be described in perpendicular (standing) well promotes, the comparison (seeing attached list) aspect lectotype selection of new collocation form and conventional arrangement form.
