Detailed description of the invention

Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.It is to be understood that It is that detailed description of the invention described herein is merely to illustrate and explains this utility model, is not used to limit This utility model processed.

In this utility model, in the case of illustrating on the contrary, " vertical, interior and outer " etc. comprises The noun of locality in term only represents this term orientation under normal service condition, or is art technology What personnel understood is commonly called as, and is not construed as the restriction to this term.

This utility model provides a kind of anti-fall lift, wherein, anti-fall carries as it is shown in figure 1, described Device for hoisting includes hanging basket the 1, first hawser the 2, second hawser 3 and elastic reset member 4；Wherein,

Described first hawser 2 one end is connected with the first rotor of the first motor 5, the other end and described hanging basket 1 is connected, so that described first motor 5 rotates and described first hawser 2 can be driven to be wound around or unclamp institute State the first rotor；

Described second hawser 3 one end is connected with the second rotor of the second motor 6, the other end and described hanging basket 1 is connected, so that described second motor 6 rotates and described second hawser 3 can be driven to be wound around or unclamp institute State the second rotor；

Described elastic reset member 4 one end is affixed, and the other end is connected with described first hawser 2；

Described second motor 6 is electrically connected to form loop with described elastic reset member 4 by wire 7, and Described loop can be connected, when described elastic reset member 3 is multiple when described elastic reset member 3 extends Described loop can be disconnected during position.

Above-mentioned design is by being connected the first hawser 2 with hanging basket 1 respectively with the second hawser 3, simultaneously by One hawser 2 is connected with the first rotor, and the second hawser 3 is connected with the second rotor, when needs promote or put During lower hanging basket 1, the first motor 5 is opened, the first hawser 2 can be realized by the rotation of the first rotor Elongate or shorten, and then hanging basket 1 is put on or is put down, and once fracture occurs in the first hawser 2, The elastic reset member 4 being connected with the first hawser 2 then can be driven to extend, when reaching certain length, elastic Reset element 4 connects with wire 7, then the second motor 6 can be made to open, and drives the second rotor to rotate, So that the second hawser 3 is wound around the second rotor, and hanging basket 1 is lifted, effectively prevent hanging basket The danger that 1 drops causes, meanwhile, above-mentioned design is without manual operation, it is to avoid artificial reaction stagnant Rear property.

So that elastic reset member 3 can contact more easily with wire 7, reduce because of bullet further Property reset element 3 and the too small hidden danger caused of wire 7 contact area, preferred in one of the present utility model Embodiment in, described elastic reset member 3 is also provided with catch, and described catch can Contact with described wire 7 or separate.Certainly, catch here can be configured according to arbitrary form, As long as make its contact area with wire 7 more greatly.For example, it is possible to be square lamellar, circular piece Shapes etc., this utility model is not limited thereto.

Certainly, so that after the first hawser 2 fracture, the second hawser 3 is avoided out during lifting The problems such as now slippage, in a kind of embodiment being more highly preferred to of the present utility model, described second rotor The collar can also be socketed with, as in figure 2 it is shown, described set ring outer surface caves inward and is formed with on outer surface Groove 8, described second hawser 3 is provided with the projection that multiple and described groove 8 phase is agreed with.So that Obtain protruding can being placed in described groove 8, it is to avoid because the second rotor outer surface long term wear occurs excessively Smooth phenomenon and cause the second hawser 3 to slip.

Certainly, hanging basket 1 can not conduct electricity, to avoid causing unnecessary safety problem, therefore, in this reality With in novel a kind of embodiment being more highly preferred to, described first hawser 2 and described second hawser 3 wrap Include stay cord and wrap up the insulation sleeve of described stay cord.

The quantity of described groove 8 can select according to actual needs, such as, of the present utility model One preferred embodiment in, the quantity of described groove 8 is 5-20.

Certainly, in order to avoid because elastic reset member 4 is too short as far as possible, cause the first hawser 2 cannot be whole Stretch, affect its utilization rate, one of the present utility model preferred embodiment in, when described elasticity When reset element 4 resets, described elastic reset member 4 length vertically is not less than described first The length of hawser 2.

Preferred implementation of the present utility model is described in detail above in association with accompanying drawing, but, this practicality is new Type is not limited to the detail in above-mentioned embodiment, in technology concept of the present utility model, The technical solution of the utility model can be carried out multiple simple variant, these simple variant belong to this reality With novel protection domain.

It is further to note that each the concrete technology described in above-mentioned detailed description of the invention is special Levy, in the case of reconcilable, can be combined by any suitable means, in order to avoid need not The repetition wanted, various possible compound modes are illustrated by this utility model the most separately.

Additionally, combination in any can also be carried out between various different embodiment of the present utility model, only Wanting it without prejudice to thought of the present utility model, it should be considered as content disclosed in the utility model equally.
