Specific implementation mode：
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
- 3 are please referred to Fig.1, when using the present apparatus, fixed seat 1 is first passed through and the device is mounted in the equipment used, lead to
It crosses bolt hole 2 to fix fixed seat 1, motor cover 3 can protect internal alternating current generator 5 and its corresponding component not by construction ring
Domestic dust and mud pollution extends the service life of the device, but also can pass through the heat dissipation positioned at 3 upside of motor cover
Window 4 carries out preferable ventilation and heat to 3 internal environment of motor cover, by distribution box 17 come so that alternating current generator 5 and power-off protection
Box 15 is connected to power supply and enters working condition, and 5 drive motor shaft 8 of alternating current generator into working condition rotates, and motor shaft 8 can drive
Driving wheel 10 rotates, and is outwardly exported the power of alternating current generator 5 by driving wheel 10, and 10 inside of driving wheel is equipped with trough of belt
12, driving wheel 10 can be suggested being driven band connection with extraneous by trough of belt 12, by transmission belt come output power；
When alternating current generator 6 happens suddenly the case where powering off during the work time, power-off protection box 15 also will appear power-off at this time
The case where, so that the magnetic induction coil 24 in power-off protection box 15 powers off, the magnetic induction coil 24 after power-off can lose magnetic
Property, so that the strong magnetic piece 23 positioned at 24 left side of magnetic induction coil loses the attraction to the right from magnetic induction coil 24,
Therefore the curved transmission arm 20 that is connect with strong magnetic piece 23 can also lose the pulling force to the right from strong magnetic piece 23, due to it is curved
18 moment of lock shaft that swing arm 20 connects by the pulling force to the left from tension spring set 19, improves oneself when curved transmission arm 20 loses
After the pulling force to the right of magnetic sheet 23, the lock shaft that is connect with curved transmission arm 20 also just lose from curved transmission arm 20 to
Right pulling force, the at this time meeting of lock shaft 18 move downward rapidly under the pulling force of tension spring set 19,18 left end of lock shaft moved downward
It can be stuck in the annular groove 13 of 10 right side wall of driving wheel moment, and blocked by the reducing gear 14 in annular groove 13,
So that driving wheel 10 slows down and static at once, just no longer outwardly output power after driving wheel 10 is static is built with driving wheel 10
The other assemblies of vertical connection also can be static at once, to protect the safety of construction site.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is appreciated that can these embodiments be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
