Description
Technical field
The present invention relates to a kind of electrician's repair apparatus, more particularly to a kind of insulating ladder of energy automatic alarm.
Background technology
In electrician's maintenance process, insulating ladder is generally used.Existing insulating ladder species is various, multi-size.Insulation
Ladder has, small volume and less weight, the characteristics of easy to use, but when in use, there is following part hidden danger：Excess load is used, and is hooked not
It is firm, incorrect, do not fix, do not help, surmount maximum height limit and use, be all the hidden danger for causing security incident.According to specification
Using standard, the rake angle on ladder and ground is 60 °, conventional single terraced non-angular identification or detection means, can not be accurate when using
True is adjusted to home；Meanwhile, when personnel scale a ladder, it is desirable to have other staff directly hold the ladder to remind and protected with hand
Protect, prevent ladder from slanting, and the footing of ladder is slammed with pin, be moved to prevent footing, but conventional insulating ladder, without substantially alert
Show or detection means, still can normally use when hand steered without personnel, there is larger potential safety hazard；In addition, ladder has when in use
Clear and definite limit for height requirement, but due to being not provided with device, when personnel enter height limiting zone, it is impossible to discover in time, easily pacify
Full accident；Finally, ladder itself has its rated capacity, and when using excess load, the use of excess load can increase safety
The incidence of accident.
The content of the invention
In view of the above-mentioned state of the art, the technical problems to be solved by the invention are that providing one kind can use
Each item data is monitored in real time in journey, and and alarm, so as to eliminate safe hidden trouble, while reminding personnel specification operation
Intelligent alarm insulating ladder.
The present invention solve the technical scheme that is used of above-mentioned technical problem for：A kind of intelligent alarm insulating ladder, including two ladders
Beam and pedal, the pedal are placed between two terraced beams, the pressure-sensitive switch that the terraced beam bottom is opened provided with control circuit, institute
Terraced beam is stated provided with the overweight warning device prohibited super warning device and controlled by contact switch, the super warning device of taboo includes mistake
The opposed infrared inductor in position and the time-delay relay being connected with the infrared inductor.
Further, it is described to prohibit super warning device input provided with wireless receiver, so as to artificial control warning device
Closing, it is easy to operate.
Further, described to prohibit super warning device also including buzzer, the buzzer is connected to time-delay relay output end,
Alarm electric signal is converted into acoustical signal.
Further, the terraced beam is provided with angle warning device, and angles when detection ladder is used, angle is not advised
Fan Shi, is alarmed.
Further, hand steered warning device is additionally provided with the terraced beam, detection scales a ladder as personnel, lacks other staff
The escalator period of the day from 11 p.m. to 1 a.m, carries out alarm.
Further, the hand steered warning device is installed on away from the 80cm-120cm of ground.
Further, the hand steered warning device is provided with buzzer and LED.
Compared with prior art, the advantage of the invention is that：The present invention uses and sets pressure-sensitive switch on terraced beam, when
When personnel scale a ladder, pressure-sensitive switch, which is pressurized, to be opened, every detection alarm activation operation on ladder, when putting on
When weight exceedes specified load-bearing on ladder, contact switch triggering is opened, and carries out overweight alarm, and reminds personnel specification operation,
So as to eliminate overweight potential safety hazard, in addition, limiting super warning device, the infrared ray sense opposed by misplacing using being set on terraced beam
Device is answered, the super warning device of triggering limit is opened when personnel enter limit superzone domain, and prompting personnel withdraw in time, it is ensured that maintenance process
Safety.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
With reference to the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Ground is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.Based on this
In invention is embodiment, and it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
A kind of intelligent alarm insulating ladder, including two terraced beams 1 and pedal 2, the pedal 2 are placed between two terraced beams 1, the ladder
The pressure-sensitive switch 15 that the bottom of beam 1 is opened provided with control circuit, when personnel step on ladder, the stress of pressure-sensitive switch 15
Closure, makes ladder be internally formed path, and the terraced bottom of beam 1 is provided with the overweight warning device 14 controlled by contact switch, and this surpasses
Weight warning device 14 includes normally opened prefabricated spring-loaded contact switch and buzzer, is touched when weight exceeds specified load-bearing on ladder
The unlatching of contact switch is sent out, driving buzzer is alarmed.It is additionally provided with parallel with one another on the terraced beam 1 and is opened by wireless remote control
Pressure out-of-limit alarming device 11, hand steered warning device 12 and angle warning device 13, the pressure out-of-limit alarming device 11 include buzzer,
The opposed infrared inductor of dislocation and the first time-delay relay being connected with the infrared inductor, when personnel enter area of transfiniting
