Description
Technical field
The utility model belongs to elevator machinery field, refers more particularly to jack, is specially a kind of spiral top lift-type jack.
Background technology
The instrument often will used when jack is the maintenance of a kind of heavy wares; we often can use the jack of fluid pressure type; this jack needs special liquid to be used as medium provides pressure; so need jack to have good leak tightness; and jack inside can produce very large expansion pressure when using; if frequently cause mechanical wear so use; then there will be leakage of oil; and cause not push up weight; and hydraulic jack relies on the joystick slowly pressurization that fluctuates to cause it to rise slowly, reduces work efficiency.
Utility model content
For the deficiency of above technology, the utility model provides a kind of spiral top lift-type jack, and its structure is simple, and without the need to leak tightness, effective bearing force is large, rise and descending speed soon, and Stability Analysis of Structures, applied widely.
For realizing above object, the technical scheme that the utility model provides is: a kind of spiral top lift-type jack, and it comprises permanent seat (1), jacking sleeve (3), threaded shaft (5), supporting seat (7), rocking bar (10), described supporting seat (7) is provided with stop sleeve (6); Described stop sleeve (6) is socketed with threaded shaft (5); Described stop sleeve (6) is provided with holding screw (8); Described threaded shaft (5) bottom is provided with rocking bar hole (9); Rocking bar (10) is socketed with in described rocking bar hole; Described threaded shaft (5) top is bolted with jacking sleeve (3); Described jacking sleeve (3) top is provided with permanent seat (1); Evenly be provided with reinforced rib (2) around described jacking sleeve (3) upper end to be connected on permanent seat (1).
Further, described reinforced rib (2) is four, and shape is right-angled triangle or right-angled trapezium.
Further, described threaded shaft (5) lower end is provided with card neck axle (501); Described card neck axle (501) lower end is provided with card end axle (502); Described holding screw (8) withstands on card neck axle (501).
Further, described permanent seat (1) is provided with four fixed orifices (11).
Further, symmetrically on the barrel of described stop sleeve (6) two holding screws (8) are bolted with.
The beneficial effects of the utility model:
1, effective bearing force of this utility model is large.
2, the rising of this utility model and descending speed fast.
3, this utility model simple and stable structure, applied widely.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.

Fig. 3 is the upward view of Fig. 1.
Shown in figure, numerical reference is expressed as: 1, permanent seat, and 2, reinforced rib, 3, jacking sleeve, 4, bush whorl, 5, threaded shaft, 6, stop sleeve, 7, supporting seat, 8, holding screw, 9, rocking bar hole, 10, rocking bar, 11 fixed orifices, 501, card neck axle, 502, card end axle.
Detailed description of the invention
The technical solution of the utility model is understood better in order to make those skilled in the art; below in conjunction with accompanying drawing, the utility model is described in detail; the description of this part is only exemplary and explanatory, should not have any restriction to protection domain of the present utility model.
As shown in Figure 1-Figure 3, structural relation of the present utility model is: a kind of spiral top lift-type jack, and it comprises permanent seat 1, jacking sleeve 3, threaded shaft 5, supporting seat 7, rocking bar 10, and described supporting seat 7 is provided with stop sleeve 6; Described stop sleeve 6 is socketed with threaded shaft 5; Described stop sleeve 6 is provided with holding screw 8; Rocking bar hole 9 is provided with bottom described threaded shaft 5; Rocking bar 10 is socketed with in described rocking bar hole; Described threaded shaft 5 top is bolted with jacking sleeve 3; Described jacking sleeve 3 top is provided with permanent seat 1; Evenly be provided with reinforced rib 2 around described jacking sleeve 3 upper end to be connected on permanent seat 1.
Preferably, described reinforced rib 2 is four, and shape is right-angled triangle or right-angled trapezium.
Preferably, described threaded shaft 5 lower end is provided with card neck axle 501; Described card neck axle 501 lower end is provided with card end axle 502; Described holding screw 8 withstands on card neck axle 501.
Preferably, described permanent seat 1 is provided with four fixed orifices 11.
Preferably, symmetrically on the barrel of described stop sleeve 6 two holding screws 8 are bolted with.
When the utility model specifically uses, first determine there are enough lubricating oils between bush whorl 4 and threaded shaft 5, determine that holding screw 8 is in releasing orientation, by rocking bar 10 through in rocking bar hole 9, rotating threaded shaft 5 makes it in retraction jacking sleeve 3, then permanent seat 2 is fixed on below the required equipment supported by fixed orifice 1, when needs are by this equipment jack-up, turn rocking bar 10 makes threaded shaft 5 rotate, until jacking sleeve 3 by this equipment jack-up to desired location, now take rocking bar 10 away, screw holding screw.
The utility model realizes rise and fall function by the rotation of screw thread and the locking of holding screw.
It should be noted that, in this article, term " comprises ", " comprising " or its any other variant are intended to contain comprising of nonexcludability, thus make to comprise the process of a series of key element, method, article or equipment and not only comprise which key element, but also comprise other key elements clearly do not listed, or also comprise by the intrinsic key element of this process, method, article or equipment.
Apply specific case herein to set forth principle of the present utility model and embodiment, the explanation of above example just understands method of the present utility model and core concept thereof for helping.The above is only preferred implementation of the present utility model, should be understood that, due to the finiteness of literal expression, and objectively there is unlimited concrete structure, for those skilled in the art, under the prerequisite not departing from the utility model principle, some improvement, retouching or change can also be made, also above-mentioned technical characteristic can be combined by rights; These improve retouching, change or combination, or the design of utility model and technical scheme are directly applied to other occasion without improving, and all should be considered as protection domain of the present utility model.
