Abstract
The utility model discloses an electric wrench for a power distribution cabinet equipped with a centrally-installed dolly and relates to the technical field of hardware appliances. The electric wrench comprises an electric wrench main body, a storage battery which can be connected with the electric wrench main body and which provides power for the electric wrench main body, a rotating head, and a lighting device. The rotating head is snapped on a connection sleeve of the output shaft of the electric wrench main body. One end of the rotating head is connected with a four-rib steel snapping rod matched with the connection sleeve. The other end of the rotating head is an inner-quadrangular aluminum alloy cylinder matched with a centrally-installed dolly switch. The lighting device is disposed on the electric wrench main body. The brightness of the lighting device is controlled by an independent lighting switch. The lighting switch is arranged on the electric wrench main body. By using the electric wrench, the labor intensity of an operator is decreased and work efficiency is increased. The short discharging time between the moving contact and the static contact of the switch effectively prevents damage on devices.

In actual use, car switch turns maintenance (cold standby) position by stand-by heat, or by overhauling (cold standby) when position turns stand-by heat, need the person on duty to use the crank manual operation, shake into shaking out and need 40 circle left and right, there are a lot of problems in this mode of operation, and the one, use crank manual operation person on duty to require great effort especially; After a plurality of switches of continued operation, operating personnel generally feel very tried and with soreness of waist arm pain phenomenon; The 2nd, the manual operation used time is longer, and the general used time, the equipment of impact stopped the power transmission operating time about 5 minutes; The 3rd, during manual operation, crank often comes off, and the careless slightly limbs that just may cause of operating personnel injure; The 4th, come off just when the switch dynamic/static contact has just separated as crank, will cause discharge for a long time between the switch dynamic/static contact, damage contact face, operation brings hidden danger to equipment.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of mid-dolly power distribution cabinet electric wrench, use described electric wrench to reduce operating personnel's labour intensity, improved operating efficiency, between the switch dynamic/static contact discharge time short, effectively prevented the infringement to equipment.
for solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of mid-dolly power distribution cabinet electric wrench, comprise the electric wrench main body and be connected the storage battery that is connected and for the electric wrench main body, provides power supply with the electric wrench main body, characterized by further comprising rotary head and lighting device, described rotary head is connected on the branch sleeve of electric wrench main body output shaft, one end of rotary head is the four rib steel kellies suitable with branch sleeve, the other end of rotary head is the interior four aluminum corner brace alloy cylinders suitable with mid-car switch, described lighting device is positioned on described electric wrench main body, the bright of described lighting device secretly controlled by independent lighting switch, lighting switch is positioned on described electric wrench main body.
Preferably: described lighting device is light-emitting diode.
Preferably: described electric wrench main body is provided with the mains electricity input end mouth.
The beneficial effect that adopts technique scheme to produce is: use described electric wrench operation to reduce operating personnel's labour intensity, after the several switches of continued operation, operating personnel's sensation and leicht fallen D/A, shortened the operating time, improved operating efficiency, each needed manual operation about 5 minutes used times, used the electric wrench operation only to need for 20 seconds; Use the electric wrench operation not there will be the crank dropping situations, reduced the possibility of operating personnel's limbs injuries; Use storage battery as power supply, make operating process safer, convenient and quick, also have the mains electricity input end mouth on the electric wrench main body, convenient in the situation that storage battery uses without electricity; Owing to using the electric wrench operation, car switch is at the uniform velocity shaken into shaking out, centrally generally not there will be break, thus between the switch dynamic/static contact discharge time short, effectively prevented equipment damage.In addition, described electric wrench main body is provided with lighting device, and lighting device can illuminate the end position of electric wrench, and handled easily personnel use in the dark.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of rotary head of the present utility model;
Fig. 3 is the right TV structure schematic diagram of Fig. 2;
Wherein: 1, electric wrench main body 2, storage battery 3, rotary head 31, four rib steel kellies 32, interior four aluminum corner brace alloy cylinders 4, lighting device 5, branch sleeve 6, lighting switch.
Embodiment
As shown in Figure 1, a kind of mid-dolly power distribution cabinet electric wrench, comprise electric wrench main body 1 and be connected the storage battery 2 that is connected and for the electric wrench main body, provides power supply with electric wrench main body 1, also comprises rotary head 3 and lighting device 4.Described rotary head 3 is connected on the branch sleeve 5 of electric wrench main body 1 output shaft, as Figure 2-3, one end of rotary head 3 is the four rib steel kellies 31 suitable with branch sleeve, the other end of rotary head is the interior four aluminum corner brace alloy cylinders 32 suitable with mid-car switch, described lighting device 4 is positioned on described electric wrench main body 1, the bright of described lighting device 4 secretly controlled by independent lighting switch 6, lighting switch 6 is positioned on described electric wrench main body 1, preferably for energy-conservation, described lighting device 4 uses light-emitting diode.In order to increase the scope of application of described electric wrench, described electric wrench main body 1 is provided with the mains electricity input end mouth.
