Description

The disconnected rope fall protection equipment of hoistable platform
Technical field
The present invention relates to elevation and subsidence mechanical equipment technical field, the disconnected rope fall arrest protection dress of specifically a kind of hoistable platform Put.
Background technology
Hoistable platform is transport personnel, the visual plant of the high empty position of instrument arrival, in order to avoid unexpected security incident is sent out Raw hoistable platform is provided with protector, and such as elevator, vertical conveyor, scaffold are generally provided with anti-falling safety device, peace The falling proof devices such as full pincers.Existing falling proof device is usually to be triggered with lapse rate, and some falling proof devices also need to foot When enough big differences in height or the speed of decline reach the setting value of device, device can just start, and can not embody release mechanism Due omnibearing protection effect, causes safety device to fail;When being either used cooperatively with electrical system, when electrical system is stopped The electricity either system failure goes wrong, and these apparatus structures are complicated and stability is poor, and there is potential safety hazard.
The content of the invention
, can be unexpected in boom hoist cable it is an object of the invention to provide a kind of disconnected rope fall protection equipment of hoistable platform The hoistable platform in high empty position is braked in rapid action during fracture, to ensure the safety of equipment and personnel.
To reach above-mentioned purpose, the technical solution used in the present invention is:
A kind of disconnected rope fall protection equipment of hoistable platform, the device are left and right symmetrically arranged in the both sides of hoistable platform vehicle frame, car Frame is respectively arranged on the left side and the right side vertical track, and track is provided with several Long Circle brake holes, and the device includes being welded on vehicle frame Hollow welding base, welding base two lower sidewalls parallel with track are provided with symmetrical elongated hole, welding base inner chamber In be provided with the sliding shoe that is adapted with the width of welding base of length, the middle part of sliding shoe is provided with through hole, coniform braking pin shaft Level runs through elongated hole and through hole and the side wall for extending welding base, and the afterbody of braking pin shaft is butt end, adjoining with track, braking The outer wall that bearing pin is placed in through hole is provided with compression spring, the both ends of the compression spring afterbody with braking pin shaft, through hole respectively Inwall top is inconsistent, and braking pin shaft, compression spring, sliding shoe can move up and down along elongated hole in welding base, banking pin The taper end of axle is anterior to be provided with nut, is arranged on the earrings at the top of the taper end of braking pin shaft and is connected with one end of steel wire rope group;
The middle part of vehicle frame is provided with the bi-lug plate of mountain shape, and the top of bi-lug plate is connected by bearing pin with lifting otic placode, bi-lug plate Both sides be respectively equipped with sheave, the other end of steel wire rope group is connected by sheave with lifting otic placode, lifts the top of otic placode Portion is connected by bearing pin with lifting big rope.
As a further improvement on the present invention, the top of the welding base is connected by bearing pin with cushion cover, buffering Elastic buffer block is provided between cover plate bottom and sliding shoe.
As the further improvement of the present invention, two opposite sides of the cushion cover are provided with what is upwardly extended Side wall, the side wall upwardly extended are connected by bearing pin with welding base;Cushion cover is set with upwardly extending the adjacent side of side wall There is the baffle plate extended downwardly, baffle plate is plugged in the inner chamber of welding base.
As the further improvement of the present invention, the buffer stopper is arranged in cushion cover.
As the further improvement of the present invention, the bi-lug plate is long pore structure with the lug plate holes on lifting otic placode.
The present invention the course of work be:
When hoistable platform is normally carried out being lifted work, lifts the dynamic lifting otic placode of big rope band and bearing pin is upward along bi-lug plate elongated hole Lifting, meanwhile, the steel wire rope group connected by lifting otic placode both sides drives braking pin shaft to overcome the active force of compression spring to retract To ad-hoc location, braking pin shaft and the brake hole of track both sides maintain a certain distance, and ensure that hoistable platform can smoothly up and down It is mobile.When lifted otic placode bearing pin be promoted to elongated hole the top of bi-lug plate when, bearing pin otic placode attachment structure work drive it is whole Individual vehicle frame starts to be lifted up.Whole lifting weight is born by bearing pin entirely in lifting process.
When the big rope of two liftings is broken simultaneously, no longer by lifting force, hoistable platform starts to fall for lifting otic placode both sides. With the whereabouts of hoistable platform, the compression spring in the present invention extends, and promotes and is translated at banking pin axial trajectory, and inserts track In the brake hole of both sides, now, braking pin shaft, compression spring and sliding shoe no longer fall, and vehicle frame can be with falling speed before Continue to fall and compress buffer stopper until hoistable platform stops falling.Braking pin shaft drives lifting otic placode by steel wire rope group simultaneously Certain distance is moved downward with bearing pin.
When left side is single lifts big fracture of rope, lifting force is provided on the right side of lifting otic placode, left side does not provide lifting force, is lifted Otic placode can rotate inclination to the left along bearing pin axis, now, the present invention in left side compression spring play a role, promote and its Inconsistent braking pin shaft is overhanging, in the brake hole of braking pin shaft insertion left rail, braking pin shaft, compression spring, sliding shoe No longer fall, vehicle frame can continue to fall and compress buffer stopper until hoistable platform stops falling with falling speed before.Simultaneously Braking pin shaft drives lifting otic placode and bearing pin to move downward certain distance by steel wire rope group.
Beneficial effects of the present invention are:
(1)The present invention is arranged on the left and right sides of hoistable platform, when needing brake hard, passes through the banking pin through welding base Mechanical braking is carried out in the brake hole that axle inserts track in the presence of compression spring, not by electric, hydraulic control system shadow Ring, securely and reliably, be not only suitable for two big fracture of rope of lifting, be also applied for the unilateral situation for lifting big fracture of rope;
(2)Present invention impulsive force caused during hoistable platform brake hard passes through braking pin shaft, sliding shoe, buffering Block, cushion cover are delivered on vehicle frame, and buffer stopper plays cushioning effect, whole hoistable platform is fallen more flat to stopped process Surely, the equipment of transport is reduced and impact dynamics that personnel are born;
(3)The present invention installs nut in the taper end of braking pin shaft, can prevent braking pin shaft from being taken off under the active force of compression spring Go out welding base;
(4)Lug plate holes in bi-lug plate and lifting otic placode are long pore structure, and bearing pin can slide up and down specific in otic placode elongated hole Distance, the distance be used for compensate braking pin shaft stretching horizontal range and buffer stopper compressed after stroke up and down.
