Description

Elevator is anti-steps on sky, fall protection equipment

Technical field

The utility model relates to a kind of elevator to be prevented stepping on sky, fall protection equipment.

Background technology

In recent years, China's elevator is stepped on sky accident and is happened occasionally, and steps on empty and falling accident number quantitative statistics according to existing news report about elevator, there are about tens such accidents every year in the whole country and occurs.The elevator safety making people take oneself that takes place frequently of these accidents creates certain distrust, also result in the great attention of governments at all levels and relevant departments.So-called " sky stepped on by elevator " event, it is simply that owing to passenger is without examining, directly strides into elevator door, and now lift car is not at this layer, thus cause passenger to fall into elevator hoistways, cause the event of personnel's heavy casualties.Used during elevator falling is that these are all hidden inside elevator, cannot observe when ordinary person takes elevator caused by the reasons such as cable breaks, aging circuit and program error.Sky stepped on by elevator, fall event creates tremendous influence to life and the social stability of people.

Utility model content

The utility model is in order to solve the problems referred to above, it is provided that a kind of safety prevents stepping on the elevator of sky, fall protection equipment.

The purpose of this utility model is achieved through the following technical solutions: a kind of elevator is anti-steps on sky, fall protection equipment, including cage, cage top is provided with infrared sensor, expansion plate is installed on slide rail bottom cage, expansion plate is connected with infrared sensor, cage top is connected by hawser guide wheel, connected by axle between guide wheel, the middle part of axle is provided with stall chuck, stall chuck is provided with spring, pilot pin, centrifugal bar, adjustable spring bolt and stop block, spring one end is connected on adjustable spring bolt, the spring other end is connected on centrifugal bar, centrifugal bar is connected on stall chuck by pilot pin, centrifugal bar front end has bayonet socket, stall chuck side is provided with braking cross bar, braking cross bar one end is fixed on wall.

Preferably, expansion plate is positioned at the top on ground.

The utility model has the advantage that multiple-protection, and security performance is high, can effectively prevent the potential safety hazard of used during elevator falling, and durable in use.

Detailed description of the invention

In order to deepen the understanding to utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment is only used for explaining the utility model, is not intended that the restriction to the utility model protection domain.

A kind of elevator as shown in Figure 1 is anti-steps on sky, fall protection equipment; including cage 1; cage 1 top is provided with infrared sensor 2; expansion plate 3 is installed on slide rail bottom cage 1; expansion plate 3 is connected with infrared sensor 2; this plate, when cage 1 often stops one layer, is controlled by infrared sensor 2, reaches flexible purpose.And the infrared sensor 2 at cage 1 top can sense each layer of stop position, so that cage 1 comes to a complete stop safely, prevent from stepping on the generation of sky phenomenon.Cage 1 top is connected by hawser 4 guide wheel 5, connected by axle between guide wheel 5, as shown in Figure 2, the middle part of axle is provided with stall chuck 6, stall chuck 6 is provided with spring 7, pilot pin 8, centrifugal bar 9, adjustable spring bolt 10 and stop block 11, spring 7 one end is connected on adjustable spring bolt 10, spring 7 other end is connected on centrifugal bar 9, centrifugal bar 9 is connected on stall chuck 6 by pilot pin 8, centrifugal bar 9 front end has bayonet socket 12, stall chuck 6 side is provided with braking cross bar 13, stall chuck 6 is arranged on inside elevator cable 4 guide wheel 5, during stall, guide wheel 5 accelerates to rotate band moving axis rotation simultaneously, have bayonet socket 12 by centrifugal bar 9 front end after the acceleration rotation of eccentricity principle stall chuck 6 to be blocked rapidly by braking cross bar 13, car is avoided to continue tenesmus.Braking cross bar 13 one end be fixed on wall 14 and every layer all arrange, expansion plate 3 is positioned at the top on ground 15.
