Description

A kind of safe deceleration vertical-type used during elevator falling rescue device
Technical field
The present invention relates to adopt umbrella shape, deceleration baffle plate, spring buffer technology, especially relate to when cab is fallen in the high-altitude that meets accident in a kind of vertical-type elevator and can save passenger's device, belong to mechanical equipment safe design technical field.
Background technology
At present, known elevator safety protection system generally is made up of machine security fender guard and electric security protector device two large divisions.The machine security fender guard mainly contains the safety guard, top car emergency exit, car top protection balustrade, toeguard of velocity limiter and safety tongs, energy disperser, drg, layer every lock and gate electric interlocking installation, door etc.; Electric security protector has protection, electric safety device of protection, the electrical accident of protection, a contact electricity of direct electric shock etc.But; still there is high-altitude elevator cage accidental falling incident to take place in practice; illustrate that also there is leak in above-mentioned two kinds of safety systems; can not prevent fully that the high-altitude free falling from taking place; protect two kinds of safety systems under the situation of actual effects all; cab is being understood the movement of falling object, will bring fatal harm to the passenger.
Summary of the invention
The objective of the invention is to overcome the deficiency of existing elevator safety protection system; the invention provides a kind of safety system; this system can all provide protection under the actual effect situation at machine security fender guard and electric security protector device; its cab can be slowed down; finally pull off a soft landing, and then play the purpose of protection passenger life.
The technical matters that solves
The present invention adopts following technical proposals to realize: top shock absorber, cab top umbrella shape speed reduction gearing, borehole wall deceleration damper gear, voice and human-computer interaction device, bottom spring bumper on self-measuring instrument apparatus, cab base plate shock absorber, the cab, above-mentioned seven kinds of devices all link to each other with central integrated control device, do not interconnect between device and the device.The self-measuring instrument apparatus is this cab rescue unit protection system-based device that falls; it can constantly be measured cab running velocity and cab and send central integrated control device to from elevator bottom height correlation data message when elevator moves; special version self-measuring instrument apparatus has hard shell protection, prevents the collision of general hard thing and impaired and then cause the fundamental measurement afunction.Central authorities' integrated control device is information collection, processing and the control center of this rescue device, and signal transmission form is wired and wireless combining, with the assurance signal transmit unimpeded, it and other device interconnecting, and to its control.Central authorities' integrated control device according to circumstances judges whether to need to start other device after receiving signal, start if desired, then central integrated control device will transmit signal to cab top umbrella shape speed reduction gearing, cab top umbrella shape speed reduction gearing starts, the speed reduction gearing that this device can start appropriate level according to the height and the velocity information decision of central integrated control device transmission, here be meant if the cab descending speed is less, start the one-level speed reduction gearing, bounce up out a umbrella shape deceleration parachute that area is less, if the cab descending speed is bigger, start double reduction, bounce up out a umbrella shape deceleration parachute that area is bigger, and open a umbellule again in the gamp vertical direction.Then top shock absorber, cab base plate shock absorber start on the cab, it will bounce up out one and be similar to safety air bag or certain thickness soft foam plastic plate is arranged, and form a kind of soft collision environment up and down with this.Borehole wall deceleration damper gear will start after receiving the signal of central integrated control device transmission, in case starts successfully, it will be to cab casing generation rubbing effect, thereby reaches certain deceleration effect.Central authorities' integrated control device passes to signal the bottom spring bumper again, and the bottom spring bumper starts the shock absorber of corresponding stage according to RST.Being installed in middle voice of cab and human-computer interaction device in this pilot process starts, after voice and human-computer interaction device start, its meeting auto alarm, and meeting and passenger's human-computer interaction, mainly be the passenger to be carried out soul comfort, report to the police and play music and wait and comfort the passenger to Lou Dong management agency when anxious.According to behind the above-mentioned treating process, when cab arrives the well head bottom, pull off a soft landing, thereby be able to protect passenger's purpose.
Beneficial effect
The invention has the beneficial effects as follows that under machine security fender guard and electric security protector device while actual effect, it is descending that cab is slowed down, and arrives the well head bottom and pull off a soft landing, thereby reach the purpose of protecting passenger's life.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a kind of elevation profile constructional drawing of safe deceleration vertical-type used during elevator falling rescue device.
1. bottom spring bumpers among the figure, the 2. borehole wall, 3. cab base plate shock absorber, 4. top shock absorber on the cab, 5. cab top umbrella shape speed reduction gearing, 6. vertical lift well, 7. cab hawser, 8. hawser pulley, 9. floor plates, 10. self-measuring instrument apparatus, 11. cab, 12. voice and human-computer interaction device, 13. borehole wall deceleration damper gears, 14. layers of door.15 central integrated control devices.
The specific embodiment
At first self-measuring instrument apparatus (10) constantly will be measured cab running velocity and cab and send central integrated control device (15) to from elevator bottom height correlation data message when elevator moves, central authorities' integrated control devices (15) according to circumstances judge whether to need to start other device after receiving signal, start if desired, then central integrated control device will transmit signal to cab top umbrella shape speed reduction gearing (5), cab top umbrella shape speed reduction gearing (5) starts, the speed reduction gearing that this device can start appropriate level according to the height and the velocity information of central integrated control device transmission, here be meant if the cab descending speed is less, start the one-level speed reduction gearing, bounce up out a umbrella shape deceleration parachute that area is less, if the cab descending speed is bigger, start double reduction, bounce up out a umbrella shape deceleration parachute that area is bigger, and open a umbellule again in the gamp vertical direction.
Then top shock absorber (4), cab base plate shock absorber (3) start on the cab, both will bounce up out one and be similar to safety air bag or certain thickness soft foam plastic plate is arranged, and form a kind of soft collision environment up and down with this.Central authorities' integrated control devices (15) transmit signal to borehole wall deceleration damper gear (13) simultaneously, borehole wall deceleration damper gear (13) will start after receiving the signal of central integrated control device transmission, in case start, device will produce rubbing effect to the cab casing.Central authorities' integrated control devices (15) pass to signal bottom spring bumper (1) again, and bottom spring bumper (1) starts the shock absorber of corresponding stage according to RST.Being installed in middle voice of cab and human-computer interaction device (12) in this pilot process starts, its meeting auto alarm, and can and passenger's human-computer interaction, mainly be the passenger to be carried out soul comfort, report to the police and the broadcast music waits and comforts the passenger to Lou Dong management agency when anxious.According to behind the above-mentioned treating process, when cab arrives the well head bottom, pull off a soft landing, thereby be able to protect the purpose of passenger's life.
