Abstract

The utility model discloses a kind of screw mandrel elevator, comprise compartment (10), fixed pulley (30), actuating device, actuating device by be connected with compartment (10) and rope (40) through fixed pulley (30) is elevated compartment (10), actuating device comprise screw mandrel (51), nut (52), motor, for limiting the limited post (53) that nut (52) rotates.Motor drives screw mandrel to rotate, and under the restriction of limited post, the nut be arranged on screw mandrel moves upward or downward, and nut is by connected rope lifting compartment.Because above-mentioned screw rod driving device is relatively steady in operational process, there will not be the unstable situation relying on winch rolling elevator rope or release elevator rope to realize in elevator cage process of rising or falling.Therefore, by the technical scheme that the utility model is above-mentioned, elevator cage can rise reposefully or decline.

Description

A kind of screw mandrel elevator

Technical field

The utility model relates to elevator technology field, in particular to a kind of screw mandrel elevator.

Background technology

In prior art, the rising of elevator cage or decline rely on winch rolling elevator rope or release elevator rope to realize.But, when winch rolling elevator rope, winch certain may be accumulated in by the rope of rolling, cause, between elevator rope, skidding occurs, and then affect the stability that elevator cage rises.When winch release elevator rope, may there is the phenomenon mutually pind down in the elevator rope being deposited in winch certain, affect the stability that elevator cage declines equally. ?

Summary of the invention

The technical matters that the utility model solves: realize in the rising of elevator cage or the process of decline at dependence winch rolling elevator rope or release elevator rope, concentrate because of elevator rope and be deposited in winch certain, cause occurring between elevator rope to skid or mutually pin down, and then affect the stability of liter or decline on elevator cage.

The utility model provides following technical scheme: a kind of screw mandrel elevator, comprise compartment, the fixed pulley be arranged on pillar, for drive on compartment rise or decline actuating device, described actuating device is by be connected with compartment and rope through fixed pulley is elevated compartment, described actuating device comprise screw mandrel, with the matching used nut of screw mandrel, for drive screw mandrel to rotate motor, for limiting the limited post that nut rotates, one end of described rope is connected with nut.

When screw mandrel elevator described in the utility model need run, operating personal makes motor energized action, and motor drives screw mandrel to rotate, and under the restriction of limited post, the nut be arranged on screw mandrel moves upward or downward, and nut is by connected rope lifting compartment.Because above-mentioned screw rod driving device is relatively steady in operational process, there will not be the unstable situation relying on winch rolling elevator rope or release elevator rope to realize in elevator cage process of rising or falling.Therefore, by the technical scheme that the utility model is above-mentioned, elevator cage can rise reposefully or decline.

As further improvement of the utility model, screw mandrel elevator described in the utility model also comprises movable pulley, and described movable pulley is fixed on compartment end face, and the other end of described rope is through movable pulley and be fixed on pillar.By mechanics principle, under the prerequisite that compartment total weight is constant, in compartment process of rising or falling, adopt the movable pulley of above-mentioned setting, the pulling force that nut applies is do not adopt movable pulley 1/2nd.So, the wearing and tearing of nut and screw mandrel can be reduced, and then improve the service life of screw mandrel and nut.

As further improvement of the utility model, described nut is provided with protrusion, and one end of described rope is connected on the protrusion of nut, and described protrusion is also connected with clump weight.The employing of clump weight can alleviate the workload of screw mandrel and nut further.

As further improvement of the utility model, described limited post offers guide groove, described nut can slide up and down in guide groove.Described limited post offers guide groove, limited post both effects of rotating of restricted nut can be made, there is again the effect of lift nut guiding.

accompanying drawing illustrates:

Below in conjunction with accompanying drawing, the utility model is described further:

Fig. 1 is the structural representation of a kind of screw mandrel elevator of the utility model;

Fig. 2 is the structural representation observing described screw mandrel elevator gained in Fig. 1 from upper left side.

Nomenclature in figure:

10-compartment; 20-pillar; 30-fixed pulley; 40-rope; 51-screw mandrel; 52-nut; 521-protrusion; 53-limited post; 60-movable pulley; 70-clump weight.

detailed description of the invention:

As shown in Figure 1 and Figure 2, a kind of screw mandrel elevator, comprise compartment 10, the fixed pulley 30 be arranged on pillar 20, the movable pulley 60 be fixed on compartment 10 end face, rope 40 through fixed pulley 30 and movable pulley 60, one end of described rope 40 is fixed on pillar 20.

Described screw mandrel elevator also comprise screw mandrel 51, with the matching used nut 52 of screw mandrel 51, for drive screw mandrel 51 to rotate motor (not shown), for limiting the limited post 53 that nut 52 rotates, described nut 52 is provided with protrusion 521.The other end of described rope 40 is fixed on protrusion 521.Described protrusion 521 is connected with clump weight 70.

In elevator real-world operation, motor first works, motor drives screw mandrel 51 to rotate, screw mandrel 51 drives nut 52 to rotate, under the restriction of limited post 53, nut 52 does along screw mandrel 51 and rises or descending motion, and nut 52 makes compartment 10 rise or decline by rope 40 and fixed pulley 30 and movable pulley 60, in the process that compartment 10 rises or declines, clump weight 70 starts booster action.

Above content is only better embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
