Accessible elevating platform of the present utility model is a kind of vertical lift machinery by the screw drive steel structure frame.This equipment directly fixes on the ground, and construction is simple, can and implement accessible transformation with the supporting installation of new old-fashioned dwelling house of sub-district.Lift platform have noise little, operate steadily, the advantage of multilevel security protection, backplate can exchange according to the needs of passage, and has safe turnover panel and base plate safety net locking function.The equipment appearance covers after with the aluminium alloy panel electrostatic plastic spraying, and waterproof is antirust, good looking appearance.This equipment meets the related request of JG5099-1988 aerial work platform standard.
Screw drive mechanism mainly is that the screw pair of utilizing screw rod and nut to form realizes relative motion, the rotating of control motor, and by bringing the mutual conversion of finishing electric energy and mechanical kinetic energy synchronously, screw rod rotates the mother nut that can drive on the bolt connection roller plate, roller plate is connecting the lift platform part, lift platform is risen and decline in this, the control of stroke can be controlled by the bound bit switch up and down.
Because the utility model is as being installed in the equipment of public place, its safety is extremely important, has therefore of the present utility modelly strengthened stationarity and the safety in the lifting process greatly with lower member.
(1) automatic panel-turnover: automatic panel-turnover is installed in the entrance at platform, and when platform rose, turnover panel was dug automatically, with platform backplate closure, forms safety door, in case wheel Wheel-chair landing in the lifting process.
(2) safety edge: be equipped with and lift platform safety edge of the same size in the platform bottom, when platform descended, the table top end opening was run into obstruction, safety edge upwards lifts, and touch inducing device, platform stop to descend immediately, in case be pressed onto people or thing, damage.
(3) high platform exit installation divider gate: in high platform exit divider gate is installed, divider gate is equipped with automatic door closer, when platform rises to high platform, triggers the mechanical lock or the electronic lock of high platform divider gate, door-lock opening, and the people can walk out platform.High platform divider gate is closed automatically and is put in place under the effect of automatic door closer, when high platform is left in platform decline, by mechanical lock or electronic lock, lock high platform divider gate, in case lift platform is when the bottom, the divider gate of high platform outlet place dress is arbitrarily opened, and the people falls from high platform.The elevating mechanism of this lift platform employing vertically-guided overhead highly is 80mm when lift platform is descended, when platform dropped to ground, turnover panel was opened automatically, formed the slope between lift platform and ground automatically, was convenient to take turns Wheel-chair and passed through.So do not need the machine hole during installation of this equipment, the basis flushes with ground and gets final product, and has solved the equipment rack long period of soaking in water, causes the corrosion of equipment steel work part, influence is used and safe problem, and it is convenient again easily to install.
(4) lift platform adopts the elevating mechanism of vertically-guided, acts on the aluminium extruded sections guide rail by eight directive wheels on the roller plate, and it is controlled to make platform reach double swerve up and down in lifting process.
(5) when the control circuit of equipment breaks down, utilize manual lowering means to descend safely and land.
(6) lift platform adopts twin-screw to drive, and can normally use in 50 ℃～-50 ℃ environment.
The operating process of screw rod-type accessible lifting platform of the present utility model is as follows:
Preparation before using: battery of electric power is full of electricity, opens gauge tap, the equipment control principle is by the transformer pressure regulation, makes the big voltage of little Current Control, thereby reaches the rotating of motor.
Uphill process: the user enters on the lift platform restfully, open the key gauge tap, long by " rising " button, the contact adhesive of control circuit repeat circuit, time-delay relay work, rising control circuit closure, motor relay work, motor just changes, transmission by synchronous band, about 8 work of two screw rods, be fixed on mother nut 11 on the roller plate 5 by worm drive, reach the effect of lifting lift platform 1.At this moment, be fixed on turnover panel roller 14 on the turnover panel in the process that rises, when touching turnover panel guide rail conjunction 13, turnover panel is packed up, and lift platform rises, to desired height, turnover panel stretches, and the limit switch block contacts with upper limit position switch, and upper limit position switch disconnects, the rising control circuit disconnects, and lift platform 1 stops to rise.The user can leave lift platform 1 reposefully.Be provided with a travel switch that transfinites in this control circuit, if damage when the bound bit switch, the lift platform warning system that continues to rise is then pointed out.
The decline process: by " decline " button, the contact adhesive of control circuit repeat circuit, time-delay relay work, decline control circuit closure, motor relay work, motor counter-rotating, by the transmission of synchronous band, about 8 work of two screw rods, by mother nut 11 transmissions, lift platform 1 descends, and turnover panel draws in, until about lower position switch, the closed-loop path disconnects, turnover panel launches automatically, shuts power supply, and user's safety is left.
In sum, equipment rack of the present utility model partly adopts the heavy in section aluminium extruded sections, and aluminium shape surface is through acid washing phosphorization, and electrostatic plastic spraying can make equipment steel work frame outward appearance clean and tidy, favorable anti-corrosion effect.Equipment lift platform surface recombination stainless steel antiskid table top or anti-skidding aluminium sheet (electrostatic plastic spraying), cabinet panel and backplate adopt electrostatic plastic spraying aluminium sheet or the stainless steel wire drawing plate of surface through overpickling, phosphatization, and the profile top grade is attractive in appearance.
Equipment of the present utility model directly fixes on the ground, and construction is simple, lift platform have noise little, operate steadily, the advantage of multilevel security protection, backplate can exchange according to the needs of passage, and has safe turnover panel and base plate safety net locking function.
Certainly, those skilled in the art in the present technique field will be appreciated that, the foregoing description only is to be used for illustrating the utility model, and be not with opposing qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in the scope of the utility model claim the variation of the foregoing description, modification etc.
