Description

Elevator hoist apparatus

Technical field

The present invention relates to a kind of lift facility, specifically, relate to a kind of elevator hoist apparatus.

Background technology

The current generally vertical lifting of elevator lifting system, the also generally use counterweight, or contact in terms of fall arrest The operation of urgent jerk is realized in the friction in face, jerk operation in vertical direction be it is very difficult, it is necessary to frictional force it is huge Greatly, fall arrest effect is poor.

In order to solve the problem present on, people are seeking a kind of preferable technical solution always.

The content of the invention

The purpose of the present invention is that in view of the shortcomings of the prior art, so as to provide, a kind of design science, security are good, prevent from anticipating The elevator hoist apparatus to fall outside.

To achieve these goals, the technical solution adopted in the present invention is：A kind of elevator hoist apparatus, including elevator Road, transmission system and arrest devices for hoisting elevator, wherein, the arrest devices include being arranged in the elevator hoistways The anti-fall track of zig-zag type, the rail wheel that slides in the anti-fall track of the zig-zag type and both ends be respectively articulated with the rail wheel With the fall prevention rope of the elevator, stop tab is hinged with each deflecting of the anti-fall track of zig-zag type, the stop tab Original state is evenly equipped with velocity sensor, controller difference to be bonded the zig-zag type anti-fall track in the elevator hoistways The stop tab is controlled to hold up rail described in backstop when connecting the velocity sensor and the stop tab to find velocity anomaly Road wheel.

It is described on base, it is evenly equipped with some stop tabs at the non-deflecting of the anti-fall track of zig-zag type.

It is described on base, it is arcuate structure at the deflecting of the anti-fall track of zig-zag type.

Described on base, the elevator hoistways include the vertical track that the four side of the corresponding elevator is set, the elevator Each side on and corresponding vertical track on electromagnet is set, the controller connects the electromagnet to find that speed is different Start the electromagnet when often.

The present invention is compared with the prior art with prominent substantive distinguishing features and significantly progressive, and specifically, the present invention is set The anti-fall track of zig-zag type is put, the anti-fall track of the zig-zag type does not influence the normal operation of elevator hoistways, can be arranged on elevator Each side corresponding in space, during elevator lifting, elevator drives fall prevention rope and rail wheel along zig-zag type track travel, Once falling, on the one hand, the transverse component of zig-zag type track with the speed of buffer falling, can extend the duration of decline, On the other hand, the speed per hour that controller is detected by velocity sensor judges exception occur, and control stop tab is holded up, the word blocked Rail wheel on type track, so as to prevent falling for elevator, even if speed is excessive, stop tab is knocked down, at each deflecting Stop tab deceleration layer by layer, also can to the greatest extent farthest mitigate elevator falling accident consequence.

Further, in order to reduce the intensity requirement for stop tab, stop tab is also provided with non-deflecting, it is more with trying one's best Stop tab buffered for the tenesmus of elevator, until stopping, playing more preferable anti-fall effect.

Further, elevator setting electromagnet is corresponded in vertical track, by electromagnet be powered magnetic force characteristic, be Elevator tenesmus increase resistance, further strengthens the anti-fall ability of elevator.

It has that design science, security are good, prevent the advantages of accidental falling.

In figure：1. elevator hoistways；2. the anti-fall track of zig-zag type；3. rail wheel；4. fall prevention rope；5. stop tab；6. speed Sensor；7. elevator；8. electromagnet.

Embodiment

Below by embodiment, technical scheme is described in further detail.

As shown in figure 1, a kind of elevator hoist apparatus, including elevator hoistways 1, the transmission system for hoisting elevator and anti-fall Equipment, wherein, the anti-fall track 2 of zig-zag type that the arrest devices include being arranged in the elevator hoistways 1, slide on it is described it Rail wheel 3 and both ends in the anti-fall track 2 of font are respectively articulated with the fall prevention rope 4 of the rail wheel 3 and the elevator 7, described Be hinged with stop tab 5 at each deflecting of the anti-fall track 2 of zig-zag type, the original state of the stop tab 5 for fitting it is described it The anti-fall track 2 of font, velocity sensor 6 is evenly equipped with the elevator hoistways 1, controller connects the velocity sensor respectively 6 and the stop tab 5 to find velocity anomaly when control the stop tab 5 to hold up rail wheel described in backstop.The zig-zag type It is arcuate structure at the deflecting of anti-fall track 2.

The anti-fall track 2 of zig-zag type does not influence the normal operation of elevator hoistways 1, can be arranged on each side of elevator 7 In corresponding space, when elevator 7 lifts, elevator 7 drives fall prevention rope 4 and rail wheel 3 along zig-zag type track travel, once send out Life is fallen, on the one hand, the transverse component of the anti-fall track 2 of zig-zag type with the speed of buffer falling, can extend the duration of decline, separately On the one hand, the speed per hour that controller is detected by velocity sensor 6 judges exception occur, and control stop tab 5 is holded up, the word blocked Rail wheel 3 on the anti-fall track 2 of type, so as to prevent falling for elevator 7, even if speed is excessive, stop tab 5 is knocked down, respectively The deceleration layer by layer of stop tab 5 at individual deflecting, it also can farthest mitigate the falling accident consequence of elevator 7, this implementation to the greatest extent It is higher for the intensity requirement of stop tab 5 in example.

In other embodiments, the difference with above example is：At the non-deflecting of the anti-fall track of zig-zag type It is evenly equipped with some stop tabs.In order to reduce the intensity requirement for stop tab, stop tab is also provided with non-deflecting, is used up The more stop tab of amount buffers for the tenesmus of elevator, until stopping, playing more preferable anti-fall effect.

For more preferable elevating fall prevention ability, the elevator hoistways 1 include the perpendicular of the four side setting of the corresponding elevator To track, electromagnet 8 is set on each side of the elevator and on corresponding vertical track, the controller connects the electromagnetism Start the electromagnet 8 when iron is to find velocity anomaly.By electromagnet 8 be powered magnetic force characteristic, for elevator tenesmus increase Add resistance, further strengthen the anti-fall ability of elevator.

Finally it should be noted that:The above embodiments are merely illustrative of the technical scheme of the present invention and are not intended to be limiting thereof；To the greatest extent The present invention is described in detail with reference to preferred embodiments for pipe, those of ordinary skills in the art should understand that：Still The embodiment of the present invention can be modified or equivalent substitution is carried out to some technical characteristics；Without departing from this hair The spirit of bright technical scheme, it all should cover among the claimed technical scheme scope of the present invention.
