Technical field
This utility model relates to vertical lift technical field, particularly relates to a kind of elevator weighing apparatus.
Background technology
Elevator is all employ, electricity in places such as numerous big and middle market, hotel, school, public place of entertainment, residential buildings
The universal of ladder brings great convenience to undoubtedly the life of people, saves a lot of valuable time.The fortune of elevator
In the trade, the weighing device of elevator is extremely important for the safe operation of elevator.
Weighing device of the prior art mainly has two kinds, a kind of structure being to use microswitch, passes through rope hitch plate
Compressing rubber, rubber compress variation reaches to touch microswitch during certain value and realizes reporting to the police, but the compression of rubber becomes
Shape amount only has certain value, and this mode detection sensitivity is low, does not reaches the requirement of accurately measurement；Another kind is to use
Pressure sensitive structure, in elevator at the bottom of non-movable sedan-chair, the pressure that rope hitch plate is given passes through pressure transducer with telecommunications
Number mode be transferred to weighing device, this signal is transferred to mainboard in the way of digital signal by weighing device again, from
And judge whether elevator overloads.Strain ga(u)ge is pasted onto on elastic sensing element by pressure transducer, then, with
Suitable mode forms electric bridge, thus the quality conversion of object is become the signal of telecommunication, and pressure transducer mainly has two parts
Composition, Part I is elastic sensing element, is the strain value of elastomer by the pressure of testee, quality conversion；
Part II is the strain ga(u)ge as sensing element, and what the strain of elastomer was synchronized by he is converted to resistance value
Change, then export after converting accordingly.The debugging of pressure transducer and the self study of weighing device are often
Bring the biggest puzzlement to installation personnel, and weighing device needs the timing of professional to debug, ensure that pressure passes
Sensor weighing data accurately, otherwise elevator can often report the fault in heavy prescription face, affects the service efficiency of elevator,
And this kind of weighing device is relatively costly, it is unfavorable for the competition of market economy.
Utility model content

Distance so that during overload, the distance trigger bit displacement sensor between displacement transducer and magnetic steel ingot sends normally closed signal,
And distance trigger bit displacement sensor between displacement transducer and magnetic steel ingot sends normally opened signal when fully loaded and unloaded.
This utility model completes the debugging of displacement transducer by the height of regulation displacement transducer, easy to operate simple fast
Victory, time saving and energy saving, it is not necessary to timing debugging, safeguard simple.
Further, through hole being offered by described connection support, displacement transducer is thereon threaded by being sleeved on
Adjusting ring device on through hole, the up-down adjustment of displacement transducer is easy to operate, and fastens firmly, it is to avoid displacement
Sensor is in use subjected to displacement and causes overload detection to be lost efficacy.
Further, described displacement transducer is symmetricly set on the both sides of static line head plate, and magnetic steel ingot is correspondingly arranged
In the both sides of movable rope head plate, improve the accuracy of detection, it is to avoid movable rope head plate run-off the straight causes detecting signal
Forbidden and erroneous judgement is occurred.
Further, described displacement transducer is positioned at the underface of magnetic steel ingot, improves detection accuracy.
Further, described static line head plate is provided with slack rope detection switch bracket, slack rope detection switch bracket
Being vertically arranged, and the upper lateral bending of slack rope detection switch bracket is to the top of movable rope head plate, slack rope detects
Device slack rope detection switch on switch bracket, the movable rope head plate below slack rope detection switch arranges slack rope detection
Touch panel.Still can make the spring on weighing device car zero load when is compressive state, when being connected with car
Cord break time slack rope situation occurs, movable rope head plate can popping up due to spring restoring force, movable fag end
Slack rope detection touch panel on plate touches slack rope detection switch and sends slack rope alarm signal, is that elevator is out of service, improves
Elevator safety in utilization.
Further, described displacement transducer uses eddy displacement sensor, and eddy current sensor can be static and dynamic
Ground noncontact, high linearity, high resolution ground measurement metal conductor measured are away from detecting head surface distance, and being that one is non-connects
The linearisation metering outfit touched, eddy current sensor can accurately measure measured body (must be metallic conductor) and sound end
Static and dynamic relative displacement change between face, accuracy of detection is high, and service life is long.
Compared with prior art, this utility model advantage is:
Elevator weighing apparatus simple in construction described in the utility model, easy for installation, debugging operations simple and fast, adjust
Joint space is big, time saving and energy saving, saves engineering and cost of labor, and the hitch rod that dry root is parallel to each other ensure that movable rope
The horizontality of head plate, the even tension of draught line, improves the service condition of pull rope, improves the use longevity of pull rope
Life, and arrange displacement transducer in the lateral symmetry of static line head plate, is effectively improved weighing precision, occur super
Can stop in time when weighing the situation with slack rope, improve the safety that elevator uses.
