Description

A kind of elevator door of high safety performance

Technical field

The utility model relates to lift facility field, has particularly related to a kind of elevator door of high safety performance.

Background technology

The application places of elevator is more and more extensive, and child is thoughtless, usually can be attached on elevator door by finger; because child points thinner, be easily drawn in crack by elevator door when enabling, because gate is operationally difficult to quick stopping; cause child to point injury, this type of accident also often occurs.

Meanwhile, be provided with safety gear in the cage door device of elevator, when sandwiching passenger's body or other article in car door, the action that can make to close the door of this safety gear stops and reversing as door opening action.At present conventional way is motor speed and the acceleration/accel of detecting gate machine, and when car door runs into obstacle in door closing procedure, then the rotating speed of motor or acceleration/accel will be affected, thus can judge whether to sandwich foreign matter.But this mode is very low for the resolution of the linear foreign matter of jewelry, expensive clothing and other valuables, as dog's leash, rope skipping.

Summary of the invention

For the deficiency that prior art exists, the purpose of this utility model just there are provided a kind of elevator door of high safety performance, has higher sensitivity and stability, not only can stop that finger enters in crack, make elevator door stop fast simultaneously, avoid human body to come to harm.

To achieve these goals, the technical solution adopted in the utility model is such: a kind of elevator door of high safety performance, comprise car door, lift car, door storage cover, described door storage cover is fixedly connected with lift car, and is provided with two corresponding openings; Described car door two ends are arranged in opening, and can receive parallel motion in cover at door; Also comprise the first proof mechanism be made up of trammel beam, pedestal and contact, described first proof mechanism is arranged in a storage cover; One end of described pedestal is fixedly installed in a storage cover, the other end is provided with piezoelectric transducer near car door place, and pedestal is connected in " work " shape by fixed link with the trammel beam near car door; Described fixed link and trammel beam junction are provided with rotating shaft; Described contact is fixedly installed in trammel beam one end, and is positioned at below piezoelectric transducer; Be fixedly connected with spring between described pedestal and trammel beam, spring is positioned at trammel beam one end away from contact; Also comprise the second proof mechanism, described second proof mechanism is arranged at a storage cover opening part, and with the first proof mechanism about car door horizontal symmetrical; Described car door opening and closing place is provided with the first groove and the second groove, is provided with deformation spring and contact element in described first groove, and deformation spring is fixedly installed between contact element and the first groove bottom land; Described second groove bottom land is installed with contact pickup.

As a kind of preferred version, described second proof mechanism is made up of fixed card slot, bolt of rear end plate and anti-clamping component, and described fixed card slot is installed on a storage cover opening part by bolt of rear end plate; Described anti-clamping component is arranged in fixed card slot.

Compared with prior art, the beneficial effects of the utility model:

1. stop elevator door fast, avoid human body to come to harm, substantially increase the safety that elevator uses;

2. prevent hand from entering into crack, avoid causing finger to crush;

3. solve existing elevator door for the low problem of the linearization resolution of jewelry, expensive clothing and other valuables, the sensitivity that improve and stability.

Detailed description of the invention

Below with reference to specific embodiment, the technical scheme that the utility model provides is described in detail, following detailed description of the invention should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model.

Embodiment:

As shown in Figure 1 and Figure 2, a kind of elevator door of high safety performance, comprise car door 1, lift car 2, door storage cover 3, described door storage cover 3 is fixedly connected with lift car 2, and is provided with two corresponding openings 31; Described car door 1 two ends are arranged in opening 31, and can receive parallel motion in cover 3 at door; Also comprise the first proof mechanism be made up of trammel beam 4, pedestal 5 and contact 6, described first proof mechanism is arranged in a storage cover 3; One end of described pedestal 5 is fixedly installed in a storage cover 3, the other end is provided with piezoelectric transducer 7 near car door 1 place, and pedestal 5 is connected in " work " shape by fixed link 8 with the trammel beam 4 near car door 1; Described fixed link 8 is provided with rotating shaft 9 with trammel beam 4 junction; Described contact 6 is fixedly installed in trammel beam 4 one end, and is positioned at below piezoelectric transducer 7; Be fixedly connected with spring 10 between described pedestal 5 and trammel beam 4, spring 10 is positioned at trammel beam 4 one end away from contact 6; Also comprise the second proof mechanism 11, described second proof mechanism 11 is arranged at storage cover 3 opening 31 place, and with the first proof mechanism about car door 1 horizontal symmetrical; Described car door 1 opening and closing place is provided with the first groove and the second groove (owing to being provided with other components in the first groove and the second groove, therefore not shown), be provided with deformation spring 12 and contact element 13 in described first groove, and deformation spring 12 is fixedly installed between contact element 13 and the first groove bottom land; Described second groove bottom land is installed with contact pickup 14; As shown in Figure 3, described second proof mechanism 11 is made up of fixed card slot 111, bolt of rear end plate 112 and anti-clamping component 113, and described fixed card slot 111 is installed on storage cover 3 opening 31 place by bolt of rear end plate 112; Described anti-clamping component 113 is arranged in fixed card slot 111.During concrete enforcement, when closing elevator, if have finger accidentally along with in the crack of car door 1 to the first proof mechanism time, trammel beam 4 makes contact presses piezoelectric transducer because of lever principle, the current potential of piezoelectric transducer changes, and sends signal to apparatus for controlling elevator, namely stops elevator door fast, avoid human body to come to harm, substantially increase the safety that elevator uses, if have finger accidentally along with car door 1 be drawn to the second proof mechanism 11 place time, owing to being provided with anti-clamping component 113, prevent hand from entering into crack, avoid causing finger to crush, and, owing to arranging detection means in car door 1 opening and closing place, when there being larger foreign matter, contact element 13 due to foreign matter direct time deformation spring 12 deformation, car door 1 open-close system is directly by car door 1 phase down, open car door 1 again, when foreign matter is as rope skipping, during the linearization of dog's leash class jewelry, expensive clothing and other valuables, car door 1 is closed, linearization is pushed to the second groove by contact element 13, there is not deformation in deformation spring 12, but because the contact pickup 14 of linearization with the second groove bottom land contacts, signal is sent to car door 1 assembly system directly by car door 1 phase down by contact pickup 14, open car door 1 again, thus improve elevator sensitivity and stability.

Finally it should be noted that, above embodiment is only in order to illustrate the technical solution of the utility model and non-limiting technical scheme, those of ordinary skill in the art is to be understood that, those are modified to the technical solution of the utility model or equivalent replacement, and do not depart from aim and the scope of the technical program, all should be encompassed in the middle of right of the present utility model.
