Description
Technical field
Technical field of crane equipment is the utility model is related to, more particularly, to monitors setting for electric hoist overload situation
It is standby.
Background technology
Electric block is a kind of conventional crane gear, slings weight by hoisting wirerope and suspension hook, may be mounted at
On the devices such as driving.Electric block has small volume, simple to operate from heavy and light, it is easy to use the features such as, be widely used in industrial and mineral enterprise
The places such as industry, storage, harbour.
Electric block has its rated load, but the Item Weight lifted by crane in actual use is sometimes more than electric block
Rated load, there is overloading.Electric block overload operation can bring unfavorable shadow to its safe operation and service life
Ring, it is therefore desirable to which the overload condition of electric block is monitored.At present, the overload monitoring of electric block and record, are relied on
It is artificial to carry out, it is impossible to monitor and record automatically.
Utility model content
The purpose of this utility model is to provide a kind of electricity for the overload condition that can automatically monitor and record electric block
Dynamic cucurbit overload monitor log instrument.
To achieve the above object, overload monitor log instrument used for electric hoist of the present utility model includes pulling force sensor, ratio
Compared with device, the first memory module for being stored with electric block rated load numerical value, for storage comparative result and overweight time
Two memory modules, the counter for storing electric hoist overload number, timing module, wireless transport module and Wireless Display
Device；
Pulling force sensor is connected in series on the hoisting wirerope of electric block, and pulling force sensor connects the comparator,
Comparator connects the first memory module, the counter and the timing module；Counter and timing module connect respectively
Second memory module, the second memory module connect the wireless transport module, and wireless transport module is connected by wireless signal
Connect the radio display.
The wireless transport module is bluetooth module or wifi module or ZIGBEE modules.
The comparator is connected with buzzer.
The utility model can monitor the overload number and surcharge preloading duration of electric block automatically when electric block works, and
The smart machine with bluetooth connection function or wifi linkage functions carried with by radio display or staff
（Such as mobile phone and tablet personal computer）Show, be highly convenient for the overload condition that staff monitors electric block, find electricity in time
The potential safety hazard of dynamic cucurbit simultaneously arranges detection and maintenance work.Due to can be caught exactly by utility model works personnel
To situation about overloading every time, therefore staff can be more clearly recognized triggering the lifting task of overload have, so as to
Afterwards overloading is reduced in the work of electric block.
Buzzer makes staff also to recognize overloading in time not before radio display, and makes in time anti-
Should.In addition, the utility model is simple in construction, convenient installation and use..
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in figure 1, overload monitor log instrument used for electric hoist of the present utility model includes pulling force sensor 1, comparator
2nd, be stored with electric block rated load numerical value the first memory module 3, second for storage comparative result and overweight time
Store 4 pieces of mould, the counter 5 for storing electric hoist overload number, timing module 6, wireless transport module 7 and Wireless Display
Device 8；
Pulling force sensor 1 is connected in series on the hoisting wirerope of electric block, and pulling force sensor 1 connects the comparator
2, comparator 2 connects first memory module 3, the counter 5 and the timing module 6；Counter 5 and timing module 6
4 pieces of the mould of the second storage, the second 4 pieces of storage mould connection wireless transport module 7 are connected respectively, and wireless transport module 7 leads to
Cross wireless signal and connect the radio display 8.
The wireless transport module 7 is bluetooth module or wifi module or ZIGBEE modules, using bluetooth module or wifi
During module, the utility model can easily connect the mobile phone or tablet personal computer of staff, more facilitate staff at any time
Monitor the overload condition of electric block.
The comparator 2 is connected with buzzer 9.
Wherein, pulling force sensor 1, comparator 2,4 pieces of mould of the first memory module 3, second storage, counter 5, timing module
6th, wireless transport module 7 and radio display 8 are prior art, and concrete structure is no longer described in detail.
In use, the pulling force sensor 1 in the utility model is connected in series on the hoisting wirerope of electric block, wirelessly
Display 8 is placed on the place of suitable staff's monitoring.When suspension hook is lifted into extreme higher position, pulling force passes hoisting wirerope
Sensor 1 is located at the lower section of electric block top pulleys, and so, pulling force sensor 1 just need not be by pulley in its stroke, can
Extend the service life of pulling force sensor 1.
During lifting, pulling force sensor 1 monitors lifting weight, and by the gravimetric value with it is electronic in the first memory module 3
Cucurbit rated load numerical value is compared, such as overweight without further action if not overweight, then to counter 5 and meter
When module 6 transmit signal, the electric hoist overload number increase that counter 5 store once, while timing module 6 metering
The secondary overweight time.When overweight phenomenon occurs, comparator 2 sends signal to buzzer 9 simultaneously, and buzzer 9 sends alarm sound, from
And prevent staff from not monitoring overloading before radio display 8.
When comparator 2 monitors that electric block is changed into non-overloading state by overload condition, to timing module 6 and buzzer
9 send signal, and timing module 6 stops this timing, the stop alarm of buzzer 9.Counter 5 and timing module 6 are by electric block
Overload number and this surcharge preloading duration pass to 4 pieces of the second storage mould；The overload number that second 4 pieces of mould of storage is stored
Information and surcharge preloading duration information are sent by wireless transport module 7, and radio display 8 receives the nothing of wireless transport module 7
Line signal is simultaneously shown on screen, so that staff easily monitors the overload number and surcharge preloading duration of electric block.
Above example is only to illustrative and not limiting the technical solution of the utility model, although with reference to above-described embodiment pair
The utility model is described in detail, it will be understood by those within the art that：The utility model can still be entered
Row modification or equivalent substitution, without departing from any modification or partial replacement of spirit and scope of the present utility model, it all should
Cover among right of the present utility model.
