Description
Technical field
The present invention relates to bridge field, specifically a kind of novel bridge facility.
Background technology
Bridge is the important foundation construction of Process of Urbanization Construction, is the important leverage for alleviating urban traffic blocking.In bridge base
More plug housing can be all preset in plinth construction, these plug housings mainly make for later stage electrification maintained equipment grafting power supply
With, but these plug housing Setting patterns are excessively simple, with being only to be kept by frictional force during electrified maintained equipment grafting
Motionless state, this power supply state is extremely unstable, when not descending the heart to kick to encounter fork or trip supply lines, it is easy to make
Come off into fork and make electrified maintained equipment accident power-off；Further, since bridge plug housing sets limited height, Er Qieqi
Internal conducting strip is set outside relatively, and this conducting strip is easy to be touched by sheet metal or metal rod, therefore, when scarce
When sheet metal or metal rod are inserted into plug housing by the people of weary awareness of safety, the easy accident got an electric shock, personnel are caused
Injures and deaths, larger potential safety hazard be present.
The content of the invention
For the deficiency of above-mentioned technology, the present invention proposes a kind of novel bridge facility.
A kind of novel bridge facility of the present invention, including the plug housing that is fixedly mounted in bridge wall body and with it is electric
Change the fork of maintained equipment connection, roll-over of the notch towards the right side is provided with the plug housing, can be pacified to turn in the roll-over
Equipped with rotating cylinder, the roll-over right-hand member is provided with projection, mutually claims the reeve groove for being provided with left and right communications and liaison in the rotating cylinder up and down, described
Inject on groove inwall and contact is installed, two groups of electrical connecting parts are provided with the reeve groove lateral wall, the electrical connecting part includes setting
Kerve is stretched in the reeve groove lateral wall and sliding is arranged on the bar that is electrically connected in stretching kerve, is set in the inwall of the roll-over
The turn hole being engaged with the bar that is electrically connected is equipped with, the turn hole radian is 90 degree, and is gradually become on direction along rotating clockwise
Shallow, tapered section of the turn hole is fixedly installed the block that is electrically connected being electrically connected with city, and the roll-over left end wall mutually claims to be provided with up and down and institute
The slippage slot for injecting groove communications and liaison is stated, is slid in the slippage slot and sliding arm is installed, the fork left end mutually claims to set up and down
There is the reeve arm being engaged with the reeve groove, the locked groove being engaged with the bar that is electrically connected is provided with the reeve arm, it is described
Fork top end right side of face is fixed with rubber column, and the one end of the rubber column away from the fork is provided with link, described
Hand grip portion is additionally provided with fork, the hand grip portion includes holding ring and valve jacket.
Further technical scheme, the kerve both sides of stretching mutually claim to be provided with to lead shifting groove, and described lead moves sliding installation in groove
Shifting block is led, the shifting groove of leading also is installed with the shifting block of leading against the stage clip of ground first, and first stage clip is to general
It is described lead move block laterally top pressure and the bar that is electrically connected is extend into the turn hole.
Further technical scheme, is installed with the slippage slot and the second stage clip that the sliding arm is connected, institute
State the second stage clip to by it is described sliding arm to the right top pressure and extend into it is described reeve groove in.
Further technical scheme, the sliding arm right side and the bar upper and lower end face that is electrically connected are disposed as hemisphere
Body.
Further technical scheme, the length of the bar that is electrically connected are equal at the length for stretching kerve and the turn hole deep trouth
Depth sum, so as to be in the described bar one end that is electrically connected in the turn hole deep trouth when, the other end with it is described inject groove outboard end
Wall is concordant.
Further technical scheme, the bar that is electrically connected are electrically connected with the contact, so as to be electrically connected in the bar that is electrically connected with described
Block can make the contact be powered when contacting.
Further technical scheme, the holding ring are fixedly installed on the fork its right end face, and the valve jacket is fixed
It is arranged on the holding ring, the holding ring and the valve jacket are semi-circular.
The beneficial effects of the invention are as follows：
Because the plug housing in apparatus of the present invention is in original state, it is described lead move block in the presence of first stage clip by
Outside top pressure and the bar outboard end that is electrically connected is extend into the turn hole deep trouth, and medial extremity and end wall on the outside of the reeve groove
Concordantly, so as to allow it is described reeve arm be inwardly inserted into, it is described sliding arm in the presence of second stage clip by top pressure to the right and
The sliding arm right-hand member is set to extend into the reeve groove, the sliding arm can prevent the rotating cylinder from turning in the presence of external force
It is dynamic, the contact can be made to keep no power；
Inject in groove when the people for lacking awareness of safety is inserted into one with metal rod and slide into sliding arm therein to the left
When in the slippage slot, because the sliding arm in another reeve groove is still able to limit the drum rotation, thus, described turn
Cylinder can not rotate, and the contact will not still be powered；And when two metal rods are inserted into two reeve grooves and will
When sliding arm therein is slid into the slippage slot to the left, due to when rotating the rotating cylinder bar medial extremity that is electrically connected can stretch
Enter into reeve groove and offseted with metal rod, therefore the bar that is electrically connected still can not be in contact with the block that is electrically connected, thus it is described
Contact will not still be powered, and can greatly reduce potential safety hazard, prevent the generation of electric shock accidents；
In use, the reeve arm is inserted into the reeve groove, when the fork left side and the plug housing right-hand member
When wall is bonded, the reeve arm left end slides into the sliding arm in the slippage slot to the left, then that the fork is suitable
Hour hands rotate 90 degree, and the fork drives the rotating cylinder to rotate clockwise 90 degree, and the bar outboard end that is electrically connected is electrically connected with described
Block offsets, and now, by the bar that is electrically connected by power transmission to the contact, and the reeve arm is inserted into the reeve groove
With the contact when middle, therefore the power supply to electrified maintained equipment can be realized；
After rotating clockwise 90 degree due to rotating cylinder, the bar medial extremity that is electrically connected is extend into the locked groove, therefore, the reeve arm
It is locked in the reeve groove and can not be extracted to the right, is accidentally kicked when encountering fork, it is not easy to fall off, therefore
It is not susceptible to the phenomenon of power-off；
After the completion of power supply, the fork is rotated counterclockwise, the fork drives the rotating cylinder to rotate counterclockwise, the rotating cylinder
After rotating counterclockwise 90 degree, the block that is electrically connected described in bar disengaging that is electrically connected, the contact can thus powered off, and when the rotating cylinder is inverse
After hour hands rotate 90 degree, the bar medial extremity that is electrically connected departs from the locked groove, so as to allow the reeve arm to extract to the right, and it is described
Plug housing can return to original state；
Apparatus of the present invention are simple in construction, easy to use, powered stable, and electrical safety is high.
