Abstract
The utility model discloses a lead screw lifter, which comprises a lead screw, a bracket, a nut, a first fixing disc, a second fixing disc and a transmission device, wherein the lead screw is in threaded connection with the nut; the lower end of the lead screw penetrates through the second fixing disc and is connected with the transmission device; the upper end of the lead screw is connected with the first fixing disc; the first fixing disc and the second fixing disc are connected with the bracket; the nut is connected with the bracket through a limiting groove in a sliding mode; a first protective cover and a second protective cover are arranged on the outer side of the lead screw; the upper end of the first protective cover is connected with the first fixing disc; the lower end of the first protective cover is connected with the nut; the lower end of the second protective cover is connected with the second fixing disc; the upper end of the second protective cover is connected with the nut; and the first protective cover and the second protective cover are rubber corrugated pipes. By the protective covers, the lead screw can be effectively protected and is prevented from being rusted, and an accident is avoided; and moreover, the protective covers are rubber corrugated pipes and can retract with the ascending and descending of the nut, so that a protection function is realized.
Description
Technical field
The utility model relates to a kind of screw-threaded shaft elevator.
Background technology
Leading screw is exposed in the air in traditional screw-threaded shaft elevator, and leading screw directly contacts with steam, and easy scale formation is got rusty, and not only production is caused to have a strong impact on, and leading screw is short service life, has increased productive costs.
The utility model content
The technical matters that the utility model will solve provides a kind of screw-threaded shaft elevator, and protective cover is along with rising, the decline of nut can be stretched, thereby the protective action of playing prevents that leading screw from getting rusty, and has avoided the generation of safety misadventure.
The technical scheme that the utility model is taked is: a kind of screw-threaded shaft elevator, and it comprises leading screw, support, nut, first reaction plate, second reaction plate and driving device; Leading screw is connected with nut thread, and the lower end of leading screw is passed second reaction plate and is connected with driving device, and the upper end of leading screw is connected with first reaction plate, and first reaction plate is connected with support with second reaction plate, and nut is through position-limited trough and support sliding block joint; There are first protective cover and second protective cover in the outside of leading screw; The upper end of first protective cover is connected with first reaction plate, and the lower end of first protective cover is connected with nut; The lower end of second protective cover is connected with second reaction plate, and the upper end of second protective cover is connected with nut; First protective cover and second protective cover are rubber bellows.
Adopt the beneficial effect that technique scheme produced to be: protective cover can effectively be protected leading screw, prevents that leading screw from getting rusty, and has avoided the generation of safety misadventure; Protective cover is a rubber bellows, along with rising, the decline of nut can be stretched, thus the protective action of playing.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Fig. 1 is the structural representation of the utility model;
1 is leading screw, and 2 is support, and 3 is first reaction plate, and 4 is second reaction plate, and 5 is driving device, and 6 is nut, and 7 is first protective cover, and 8 is second protective cover.
The specific embodiment
A kind of screw-threaded shaft elevator, it comprises leading screw 1, support 2, nut 6, first reaction plate 3, second reaction plate 4 and driving device 5; Leading screw 1 is threaded with nut 6; The lower end of leading screw 1 is passed second reaction plate 4 and is connected with driving device 5; The upper end of leading screw 1 is connected with first reaction plate 3, and first reaction plate 3 is connected with support 2 with second reaction plate 4, and nut 6 is through position-limited trough and support 2 sliding block joints; There are first protective cover 7 and second protective cover 8 in the outside of leading screw 1; The upper end of first protective cover 7 is connected with first reaction plate 3, and the lower end of first protective cover 7 is connected with nut 6; The lower end of second protective cover 8 is connected with second reaction plate 4, and the upper end of second protective cover 8 is connected with nut 6; First protective cover 7 and second protective cover 8 are rubber bellows.
The utility model leading screw is connected with nut thread, and when leading screw rotated through driving device, nut rose or descends, thereby compresses first protective cover or second protective cover, and protective cover can get rusty by actv. protection leading screw non-scaling.
