Abstract

The utility model discloses a device for preventing an elevator from falling. The device comprises a central control module, a velocity sensor, an A/D converter, a plurality of resistance modules, a safety air bag and a damping spring, wherein the central control module, the velocity sensor and the A/D converter are arranged on a lift car of the elevator, the safety air bag and the damping spring are installed at the bottom of the lift car of the elevator, and the resistance modules are evenly arranged on the outer side of the lift car of the elevator. The velocity sensor is connected with the central control module through the A/D converter, sensed velocity data are transmitted to the central control module after A/D conversion is carried out on the sensed velocity data, the central control module judges whether the resistance modules are started or not according to the received data, triple-production is adopted, elevator accidents are prevented, the device is simple in structure, easy to achieve and worthy of wide popularization, and safety of passengers in the elevator can be better guaranteed.

Description

A kind of device that prevents elevator tenesmus

Technical field

The utility model relates to elevator field, particularly a kind of device that prevents elevator tenesmus.

Background technology

Along with increasing of high buildings and large mansions, the usage quantity of elevator is also more and more, the frequency that elevator faults occurs is also more always higher, especially the elevator in high building, the situation that elevator drops rapidly happens occasionally, and has caused and serious injures and deaths and loss, when elevator drops, velocity limiter and the safety tongs fault of elevator are described, the passenger safety in elevator has just been subject to greatly threatening, so how to prevent that the generation of elevator safety accident from having become current problem demanding prompt solution.

Utility model content

The utility model, for the defect of background technology, has proposed a kind of device that prevents elevator tenesmus, adopts triple protection, and the generation of prevention elevator accident is simple in structure, is easy to realize, and better guarantees the safety of passenger in elevator, is worth promoting.

In order to address the above problem, the technical solution of the utility model is as follows:

A kind of device that prevents elevator tenesmus, comprise Central Control Module (CCM), speed sensor, A/D converter, several resistance module, safety air bag and damping spring, described Central Control Module (CCM), speed sensor and A/D converter are all located on lift car, described safety air bag and damping spring are arranged on lift car bottom, and several resistance modules are evenly arranged on lift car outside.

As further prioritization scheme of the present utility model, nitrogen is equipped with in described safety air bag inside.

As further prioritization scheme of the present utility model, described safety air bag thickness is 100cm.

As further prioritization scheme of the present utility model, described resistance module comprises projector, steel rope and steel nail, and described projector is fixed on lift car outside, and the two ends of steel rope connect respectively projector and steel nail.

The utility model adopts above technical scheme compared with prior art, has following technique effect:

The first, adopt multiple protective, the personal security of the elevator inside of can actv. protection falling;

The second, be skillfully constructed, novel structure;

Three, circuit is simple, sensitieness is high, making is simple, be worthy to be popularized.

Accompanying drawing explanation

Fig. 1 is circuit diagram of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail:

A kind of device that prevents elevator tenesmus, structure as shown in Figure 1, comprise Central Control Module (CCM), speed sensor, A/D converter, several resistance module, safety air bag and damping spring, described Central Control Module (CCM), speed sensor and A/D converter are all located on lift car, described safety air bag and damping spring are arranged on lift car bottom, and several resistance modules are evenly arranged on lift car outside; Described speed sensor is connected with Central Control Module (CCM) via A/D sensor, and the speed data sensing is carried out sending into Central Control Module (CCM) after A/D conversion, and Central Control Module (CCM) judges whether starting resistance module according to the data that receive.

Resistance module comprises projector, steel rope and steel nail, and described projector is fixed on lift car outside, and the two ends of steel rope connect respectively projector and steel nail, described projector is after receiving the actuation signal of Central Control Module (CCM), steel nail is fixed on to elevator inwall, regulate the length of steel rope simultaneously, there is the program writing in advance Central Control Module (CCM) inside, when the speed signal detecting when speed sensor has surpassed the threshold value of Central Control Module (CCM) internal processes setting, Central Control Module (CCM) transmitted signal starting resistance module, the projector of resistance inside modules is the steel rope with steel nail to hoistway wall transmitting, steel rope adopts German enlightening handkerchief steel rope, there is very outstanding elasticity, and counter-bending fatigue property, can effectively stop the tenesmus of elevator, nitrogen is equipped with in the safety air bag inside of elevator bottom, when being squeezed, safety air bag plays buffer action, when balloon rupture, inner nitrogen can antagonistic force, slow down the impulsive force that elevator clashes into, the spring of elevator bottom is after safety air bag breaks simultaneously, continue to play buffer action, guarantee the inner passenger's of elevator safety.
