Description
Technical field
The present invention relates to a kind of crane gear intelligent limit and phonetic alarm device.
Background technology
Crane gear has been become since the industrial revolution as essential lifting tool, accounts for important in nation-building industry
Status, also one of mark as scientific and technological progress.But suspension hook often occurs during the use of enterprise and rushes to summit shell
Top is flat or breaks steel wire rope, its main cause:Though 1. limited location bar and two small backstops above crane gear, because of backstop screw
Loosening causes failure.2. stir backstop it is spacing be to stir circuit fire stop disconnecting circuit by the baffle plate on rope guide to obtain,
Because craneman often sideling draws in lifting cargo, sideling hang, and lifting rope device can't stand the strength of oblique pull because holding, and make steel
Band breaks failure, and circuit fire stop is also just into a kind of ornaments.It is and operator has a kind of phychology of solidification sometimes, i.e., limited above
Bit switch, just bold continuation rises, and hardly realizes that broken belt weight high-altitude of rushing to summit is fallen down, easily causes human casualty accident.
The content of the invention
It is an object of the invention to provide a kind of crane gear intelligent limit and phonetic alarm device, to overcome prior art
Above shortcomings.
The purpose of the present invention is to be achieved through the following technical solutions：
A kind of crane gear intelligent limit and phonetic alarm device, including fixed plate, the fixed plate is provided with intelligence
The total unit of limiter, the total unit of Intelligent position limiter includes anti-askew skewing device for hoisting, disconnected control limit switch, voice module and disconnected
Fiery limiter；The bottom of the fixed plate is connected with an inclined limit top plate, is provided with close to the limit top plate end
Spacing Hall magnetic control, the lower section of the limit top plate is provided with spacing report magnetic control；Spacing report magnetic control, disconnected control limit switch and limit
Position Hall magnetic control is all connected with voice module.
Further, the anti-askew device for hoisting that skews includes limiter and prevents askew skew in the middle of pendent switch, the limiter
Both sides be respectively provided with a spring.
Further, the anti-askew pendent switch that skews connects voice module.
Beneficial effects of the present invention are：The intelligent limit and phonetic alarm device askew skew device for hoisting and intelligence provided with anti-
Can the total unit of limiter, prevent crane gear it is askew skew to hang break steel wire rope and suspension hook is rushed to summit.

Embodiment
As Figure 1-4, a kind of crane gear intelligent limit and phonetic alarm device, including fixed plate 1, the fixation
Plate 1 is provided with the total unit 2 of Intelligent position limiter, and the total unit 2 of Intelligent position limiter includes that anti-askew to skew device for hoisting 3, disconnected control spacing
Switch 4, voice module 5 and circuit fire stop 6；The bottom of the fixed plate 1 is connected with an inclined limit top plate 7, close
The end of limit top plate 7 is provided with spacing Hall magnetic control 8, and the lower section of the limit top plate 7 is provided with spacing report magnetic control 9；Limit
Position report magnetic control 9, disconnected control limit switch 4 and spacing Hall magnetic control 8 are all connected with voice module 5.It is described to prevent that the askew device for hoisting 3 that skews is wrapped
Include limiter and prevent that the askew both sides skewed in the middle of pendent switch 10, the limiter are respectively provided with a spring 11, spring 11 during installation
It is located at the both sides of steel wire rope 15.The anti-askew pendent switch 10 that skews connects voice module 5.
When specifically used, the intelligent limit and phonetic alarm device are applied on all crane gears, below with electricity
Dynamic cucurbit is that object introduces its installation and operation principle：
Fixed plate 1 is arranged between two steel wire ropes 15 of connecting shackle device 14 and positioned at the lower end of rope guide clamping plate 13,
When suspension hook rises to the nearly 400mm in the lower end of limit top plate 7 close to spacing report magnetic control 9, voice module 5 will be sent " close to spacing
, take care " prompt tone, remind operator note.
If being further continued for rising, suspension hook shell upper top to limit top plate 7, touch disconnected control limit switch 4, now rise
Contactor coil is cut off, and leaves the motor off operation, while disconnected control limit switch 4 normally opened contact closure connects voice module 5, is sent
The warning of " spacing, to take care ", while infrared shot-light directive ground teaching process person.
If disconnected control limit switch 4 fails, suspension hook continues to rise, and the thimble of circuit fire stop 6 is pushed, makes the two of motor
Circuitry phase is cut off, and motor stopped operating.The spacing Hall magnetic control 8 being placed in simultaneously in limit top plate 7 is normal under the sensing of magnet
Open contacting, voice module 5 sends the warning of " cutoff is spacing, takes care ", infrared shot-light also directive ground is informed
Operator is spacing.
If operator will rise, hanging object is askew to be skewed when hanging more than 3.5 degree, and the deformation of spring 11 touches the contact built in limiter, will
Main contactor coil circuit is cut off, complete machine is stopped, and voice module 5 sends carrying for " safety first not allowing askew skew to hang "
Show sound, while infrared shot-light directive ground, teaching process person.
When a hanging object recovers normal, motor will run well again.In summary, it is ensured that rope guide is difficult to break, suspension hook
Do not rush to summit, protect the safety of operator and equipment.
The present invention is not limited to above-mentioned preferred forms, and anyone can show that other are various under the enlightenment of the present invention
The product of form, however, make any change in its shape or structure, it is every that there is skill identical or similar to the present application
Art scheme, is within the scope of the present invention.
