Abstract
The utility model relates to a battery automatic-charging device for hanging balances. The utility model is characterized in that an electricity supplying device is arranged under a dead pulley on a crane; an electricity receiving device is arranged above a spacing device of a hook 5. When the hook is lifted to a certain height, the electricity supplying device contacts the contact of the electricity receiving device to complete the charge of a hanging balance. The utility model can make the voltage of batteries of the hanging balance in a normal state and avoids the fault that the hanging balance can not work normally caused by the shortage of the voltage of the batteries.
Description
The utility model relates to a kind of charging device of steelyard battery.
The supplying cell of existing steelyard must be removed after work a period of time, changed new battery.Simultaneously the battery that takes off is carried out charging process.Change battery once untimely, will damage battery, even also can damage steelyard.
The purpose of this utility model is to provide a kind of charging device of finishing the steelyard battery charge in the crane course of work.
The utility model comprises: power supply lead-in wire 1, last electric supply installation, current-collecting device and lead-in wire 8; One end of described power supply lead-in wire 1 is connected with power supply, and the other end is connected with last electric supply installation; Below the crane fixed pulley, the last electric supply installation of being made up of last power supply contact 3 and the soft fixing body 2 with retractility is installed; Current-collecting device is made up of the contact 4 of stop 5 tops that are installed in suspension hook 6; The contact 3,4 of last electric supply installation and current-collecting device when suspension hook 6 rises to above the operate as normal specified altitude, can contact; One end of described lead-in wire 8 is connected with the contact of current-collecting device, and the other end is connected with the power end of steelyard 7.
Automatic charge device provided by the utility model can make the cell voltage of steelyard be in normal condition all the time, has avoided causing because of the cell voltage deficiency fault of steelyard cisco unity malfunction.
The drawing explanation:
Fig. 1 is a Facad structure schematic diagram of the present utility model.
Fig. 2 is a side structure schematic diagram of the present utility model.
Embodiment of the present utility model sees accompanying drawing: be the electric supply installation lead-in wire 1.; 2. soft fixing body; 3. be last electric supply installation contact; 4. the contact of current-collecting device; 5. be stop; 6. be suspension hook; 7. be steelyard; 8. be lead-in wire.Under the crane fixed pulley, install electric supply installation, on the crane gib head, current-collecting device is installed, when crane is not worked, the crane gib head must be raised to one more than the specified altitude, and this highly is operate as normal time institute is inaccessible.And automatically the device of charging just is installed on this height, once after the gib head lifting altitude surpassed specified altitude, the electric supply installation pulley under and the current-collecting device on the gib head were in contact with one another, the automatic charging.Owing to adopt soft contact, thereby can not damage because of collision.Steelyard 7 charging beginnings, accumulative total charging interval every day is 15 minutes.Crane once more during the lift heavy thing suspension hook descend, throw off with current-collecting device contact 4 last electric supply installation contact 3, the charging end.If each charging surpasses charging voltage, system can stop charging automatically.
