Description
Technical field
The utility model relates to a kind of screw mandrel, relates in particular to a kind of safety nut of screw mandrel for bay-lift mechanism.
Background technology
Electric lifting platform is widely used in locomotive paint, the rising of bay-lift and decline are all by two cocainine stem nut auxiliary driving, because feed screw nut commonly used is generally the tin bronze material, screw mandrel than steel is easy to wear, therefore the long-term back nut negative thread that uses ruptures, cause the bay-lift landing, have very large potential safety hazard.
Summary of the invention
The technical problems to be solved in the utility model is: feed screw nut commonly used is generally the tin bronze material, screw mandrel than steel is easy to wear, therefore the long-term back nut negative thread that uses ruptures, cause the bay-lift landing, there is very large potential safety hazard, a kind of safety nut of screw mandrel for bay-lift mechanism is provided.
In order to overcome the defect that exists in background technology, the technical scheme that its technical matters that solves the utility model adopts is: this safety nut of screw mandrel for bay-lift mechanism comprises bay-lift, the bay-lift two ends are provided with feed screw nut pair, be provided with screw mandrel safety nut mechanism in feed screw nut pair, described screw mandrel safety nut mechanism comprises feed screw nut and safety nut, the feed screw nut is installed on the nut permanent seat, feed screw nut and safety nut are the up and down reverse geometry, described safety nut is provided with and pulls pin, Compress Spring and gland, and gland is fixed by screw.
According to another embodiment of the invention, further comprise between described feed screw nut and safety nut and be provided with gap.Can change by the observation gap, judge whether the feed screw nut damages.
The beneficial effects of the utility model are: this safety nut of screw mandrel for bay-lift mechanism design is simple, easy for installation, can significantly improve the use safety of electric lifting platform, also can use in similar feed screw nut auxiliary drive gear simultaneously, very large promotional value is arranged.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation that in Fig. 1, A section amplifies;
Fig. 3 is the structural representation that in Fig. 2, B section amplifies;
Wherein: 1, feed screw nut pair, 2, bay-lift, 3, the nut permanent seat, 4, the feed screw nut, 5, safety nut, 6, pull pin, 7, Compress Spring, 8, screw, 9, gland.
The specific embodiment
As shown in Figure 1, comprise bay-lift 2, bay-lift 2 two ends are provided with feed screw nut pair 1, and the rising of bay-lift 2 and decline are all by secondary 1 transmissions of two cocainine stem nuts.Be provided with screw mandrel safety nut mechanism in feed screw nut pair 1.Safety nut mechanism is set on feed screw nut pair, can improves the safety performance of total.
As shown in Figure 2, described screw mandrel safety nut mechanism comprises feed screw nut 4 and safety nut 5, and feed screw nut 4 is installed on nut permanent seat 3, feed screw nut 4 and safety nut 5 are the up and down reverse geometry, feed screw nut's 4 load-bearing, safety nut 5 is servo-actuated, between two nuts, certain interval is arranged.。
As shown in Figure 3, described safety nut 5 is provided with and pulls pin 6, Compress Spring 7 and gland 9, and gland 9 is fixing by screw 8.
Be provided with gap between feed screw nut 4 and safety nut 5.Change by observation feed screw nut 4 and safety nut 5 gaps, can judge whether feed screw nut 4 damages.
In the bay-lift working process, feed screw nut 4 damages suddenly, and safety nut 5 can replace feed screw nut's load-bearing, prevents the bay-lift landing, to guarantee safety.As the expeditious measures of maintenance of equipment, safety nut can be by oppositely installing, to substitute feed screw nut's work temporarily simultaneously.
This screw mandrel safety nut mechanism design is simple, easy for installation, can significantly improve the use safety of electric lifting platform, also can use in similar feed screw nut auxiliary drive gear simultaneously, and very large promotional value is arranged.
