Abstract
The utility model discloses a lifting drum's barrel, including hollow barrel body, the barrel body comprises left side section even as an organic whole, middle section and right side section, and the diameter in middle section all is greater than the diameter of left side section and right side section, all is equipped with the helicla flute on the outer peripheral face of left side section, middle section and right side section. This barrel simple structure, need not change motor speed just can realize that heavy object translation rate changes, can show the improvement operating efficiency.
Description
Technical field
The utility model relates to a kind of cylindrical shell of lifting drum.
Background technology
The cylindrical shell of existing lifting drum is isometrical, and its outer peripheral face is provided with the plug helix for lay winding wire ropes.When winch rotating speed is certain, the rotating speed of cylindrical shell is also certain, and that is, the moving velocity of wire rope pulling weight is also certain.But in order to raise the efficiency, weight is from the process of origin-to-destination, and initial period needs weight to move at a slow speed, and the intermediary needs weight quick travel, and ending phase needs again weight to move at a slow speed.At present, the change of above-mentioned speed is realized by the rotating speed of change motor, thus make the control circuit of winch become complicated, easily breaks down.
Summary of the invention
The technical problems to be solved in the utility model is for above-mentioned defect, provides a kind of need to change the cylindrical shell that motor speed just can realize the lifting drum that weight moving velocity changes.
In order to solve the problems of the technologies described above, the utility model provides a kind of cylindrical shell of lifting drum of following structure, comprise the cylindrical shell body of hollow, its constructional feature is: described cylindrical shell body by left section that is connected as a single entity, stage casing and right section form, the diameter in stage casing is all greater than the diameter of left section and right section, left section, the outer peripheral face of stage casing and right section is equipped with plug helix.
Described left section, plug helix on stage casing and right section connects successively, thus on the outer peripheral face of cylindrical shell body, forms continuous print plug helix.
Left section identical with the diameter of right section.
The left end of described cylindrical shell body is connected with left end cap, and the right-hand member of cylindrical shell body is connected with right end cap; Left end cap is provided with left mounting hole, and right end cap is provided with right mounting hole.
Described left mounting hole and right mounting hole are arranged with one heart.
Be connected with adapter sleeve in described right mounting hole, in described left mounting hole, be connected with adapter shaft.
Cylindrical shell body is set as the three-stage structure be connected as a single entity by the utility model, the diameter of its left section and right section is all less than the diameter in stage casing, like this when motor speed is constant, in the unit time, the length being wound on the upper steel rope of left section and right section is less than the length around the steel rope on stage casing; In other words, steel rope can make weight move at a slow speed when reeling on left section and right section, weight quick travel can be made when steel rope reels on stage casing, due to steel rope winding by from left to right or dextrosinistral order carry out, therefore can obtain the beginning of weight moving process and ending phase is slack-off, the intermediary accelerate effect, can operating efficiency be significantly improved.
In sum, the utility model has the advantage of: structure is simple; Do not need to change motor speed and just can realize the change of weight moving velocity, can operating efficiency be significantly improved.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, the cylindrical shell of lifting drum comprises the cylindrical shell body 1 of hollow, described cylindrical shell body 1 by left section 11 that is connected as a single entity, stage casing 12 and right section 13 form, the diameter in stage casing 12 is all greater than the diameter of left section 11 and right section 13.Left section 11 and right section 13 is generally isometrical setting, certainly also can not isometrical setting according to requirements.Left section 11, the outer peripheral face of stage casing 12 and right section 13 is equipped with plug helix.Described left section 11, plug helix on stage casing 12 and right section 13 connects successively, thus on the outer peripheral face of cylindrical shell body 1, forms continuous print plug helix 7.
Continue with reference to Fig. 1, the left end of described cylindrical shell body 1 is connected with left end cap 2, and the right-hand member of cylindrical shell body 1 is connected with right end cap 3; Left end cap 2 is provided with left mounting hole, and right end cap 3 is provided with right mounting hole.Described left mounting hole and right mounting hole are arranged with one heart.Be connected with adapter sleeve 5 in described right mounting hole, in described left mounting hole, be connected with adapter shaft 6.
Occupation mode of the present utility model is with reference to Fig. 2, and adapter shaft 6 is rotatably connected on bracing frame 8, and adapter sleeve 5 is connected with the rotor shaft power of motor 9.The utility model also can not establish adapter sleeve 5 and adapter shaft 6, is rotationally connected by left mounting hole and bracing frame, is connected with motor power by right mounting hole.
