Used during elevator falling protector

Technical field

The present invention relates to a kind of used during elevator falling protector, belongs to fixed-site technical field of crane equipment.

Background technology

With the development of national economy, elevator has become people's production and indispensable instrument of living, although work as this life The elevator of product all has fairly perfect safety guard, but the accident of lift car accidental falling still happens occasionally, Give people to cause different degrees of injury and property loss, social repercussion is very big.

The content of the invention

The present invention is in order to make up the defect of prior art, there is provided a kind of simple structure, can be in lift car accidental falling When prevent its rapid decrease, so as to avoid accident occur used during elevator falling protector.

The present invention is achieved through the following technical solutions：

A kind of used during elevator falling protector, including support, being provided with support can be around the interior body of main axis, and interior body includes sampling Runner, trigger mechanism and actuator, it is characterised in that：Described sampling roller centre is provided with steel axis, steel axis two End is fixed on interior side plate by F207 bearing blocks, and sampling runner one end is provided with synchronous bull wheel；Trigger mechanism includes that triggering turns Wheel, centrifugation trigger head and frizzen, centrifugation trigger head are symmetricly set on triggering runner vertical diameter direction, and triggering runner passes through axle The F201 bearing blocks at two ends are fixed on interior side plate, and triggering runner one end is provided with synchronous steamboat, synchronous steamboat by Timing Belt with Synchronous bull wheel connection；Actuator includes relieving mechanism and lockable mechanism, samples runner and drives operating by the suspender belt sought connections with thereon, Suspender belt upper end connects elevator car upper, passes sequentially through support lower inlet, sampling runner, locking boots, support outlet, upper guiding cunning Wheel, middle leading block, lower leading block, bottom leading block, after tensioning extension spring, lower end is connected to cage bottom.

Wherein：

Described relieving mechanism includes clockwork spring handwheel, spool, drawstring and interior body pin, and lockable mechanism is made up of locking boots.

Described support is processed by HT300 casting, is mounted in elevator(lift) machine room above spandrel girder, samples runner Diameter 300mm, width 200mm, the steel axis that there are length 380mm, diameter 40mm in center are passed through, by Timing Belt Rotating speed is lifted into 3 times of transmission and synchronous steamboat, triggering runner is made by organic material, diameter 300mm, thickness 20mm, from The steel column that have spring pulling of the line trigger head diameter 16mm steel pipes built with diameter 14mm, when reaching setting speed, steel column is stretched Go out steel pipe triggering.

Described suspender belt is worked out by organic materials such as terylene, polypropylene and nylon, width 100mm, thickness 3mm, The pulling force of 40000N can be carried, its length cutting as needed, suspender belt are run leading block and made by organic material, diameter 50m M, width 150mm, two ends install bearing, are fixed on elevator hoistways inwall or other appropriate places by the end ear at two ends.

The locking boots are made by organic material, width 200mm, vertically the tongue and groove of radius of machining 10mm.

The present invention is realized by following operation principle：Power of the present invention drives suspender belt operation from lift car, from And drive sampling runner, synchronous bull wheel, Timing Belt, synchronous steamboat, triggering runner to rotate successively, when lift car decrease speed reaches During to 3 times of normal speeds, the steel column that trigger head is centrifuged on runner is triggered because centrifugal force overcomes the pulling force of its extension spring to stretch out steel pipe, Frizzen is touched, clockwork spring handwheel is discharged, clockwork spring drives spool winding drawstring, withdraws interior body pin, and interior body is in support around main shaft Rotate, due to sampling the distance between runner stress point and locking boots impetus and main shaft, to differ twice more, so locking boots pair The pressure of suspender belt（Resistance）It is more than the big twice of impulsive force produced than car rapid decrease, once so triggering, high intensity suspender belt Will be out of service, prevent lift car from continuing to decline.

The invention has the beneficial effects as follows：Simple structure, it is not necessary to power supply, energy saving；It is reliable, it is durable in use, protect Hinder the safe operation of elevator, maintain the life security of people；Cost is low, easy to utilize.

Specific embodiment

Accompanying drawing is the specific embodiment of the present invention.

Used during elevator falling protector as depicted in figs. 1 and 2, including support 1, is provided with what is can rotated around main shaft 18 in support 1 Interior body, interior body include sampling runner 2, trigger mechanism and actuator, it is characterised in that：Described 2 center of sampling runner is provided with Steel axis 4,4 two ends of steel axis are fixed on interior side plate by F207 bearing blocks 5, and 2 one end of sampling runner is provided with synchronization Bull wheel 6；Trigger mechanism includes triggering runner 3, centrifugation trigger head 7 and frizzen 13, and centrifugation trigger head 7 is symmetricly set on triggering and turns 3 vertical diameter directions are taken turns, runner 3 is triggered and interior side plate, 3 one end of triggering runner is fixed on by the F201 bearing blocks 8 at axle two ends Synchronous steamboat 9 is provided with, synchronous steamboat 9 is connected with synchronous bull wheel 6 by Timing Belt；Actuator includes relieving mechanism and locking machine Structure, sampling runner 2 drive operating, 12 upper end of suspender belt connection elevator car upper to pass sequentially through machine by the suspender belt 12 sought connections with thereon Seat lower inlet, sampling runner 2, the outlet of locking boots 11, support, upper leading block, middle leading block, lower leading block, bottom After leading block, tensioning extension spring, lower end is connected to cage bottom.

Relieving mechanism includes clockwork spring handwheel 14, spool 15, drawstring 16 and interior body pin 10, and lockable mechanism is by 11 groups of locking boots Into locking boots 11 are made by organic material, width 200mm, vertically the tongue and groove of radius of machining 10mm.

Power of the present invention drives suspender belt 12 to run from lift car, so as to drive successively sampling runner 2, synchronous bull wheel 6, Timing Belt, synchronous steamboat 9, triggering runner 3 are rotated, and when lift car decrease speed reaches 3 times of normal speeds, trigger runner 3 On the steel column of centrifugation trigger head 7 overcome the pulling force of its extension spring to stretch out steel pipe because of centrifugal force, touch frizzen 13, discharge clockwork spring handss Wheel 14, clockwork spring 17 drive the winding drawstring 16 of spool 15, withdraw interior body pin 10, and interior body is rotated around main shaft 18 in support, due to It is many that the distance between sampling 2 stress point of runner and 11 impetus of locking boots and main shaft 18 differ twice, so 11 pairs, locking boots hang With 12 pressure（Resistance）It is more than the big twice of impulsive force produced than car rapid decrease, once so triggering, high intensity suspender belt 12 will be out of service, prevents lift car from continuing to decline.

The present invention both can design its installation site in elevator design, it is also possible to transform existing elevator：In elevator(lift) machine room Make above interior spandrel girder not less than 150mm × 100mm square holes, main frame support 1 is fixed by expansion bolt or other bolts In this, when car is in top layer, and 12 offset from perpendicular of high intensity suspender belt of its top connection cannot be greater than 10 °, high intensity With hole wall friction, leading block, suspender belt 12 must not should ensure that the operation of high intensity suspender belt is straight, not inclined not around car bottom when running Tensioning extension spring, should ensure that high intensity suspender belt sampling runner 2 on it is non-slip.
