Description
Technical field
The present invention relates to tramcar technical field, in particular to a kind of annular pantograph and tramcar.
Background technology
At present, in the related art, existing tramcar when out of service, it is necessary to be pulled by manpower manual by electricity
Bow, so that pantograph departs from contact net, so as to realize the power-off to tramcar, but such a mode needs driver to draw manually
Drag, not only operating efficiency is low, and working strength is big, and has certain risk, may produce injury to driver, therefore, such as
What design is a simple in construction, can safety operation, operating efficiency is high, and the low pantograph of working strength is very important.
The content of the invention
It is contemplated that at least solves one of technical problem present in prior art or correlation technique.
Therefore, the first aspect of the present invention proposes a kind of annular pantograph.
The second aspect of the present invention proposes a kind of tramcar.
In view of this, the first aspect of the present invention provides a kind of annular pantograph, and annular provided by the present invention is by electricity
Bow, for tramcar, contact net is powered for tramcar, and annular pantograph includes：Bearing, body, motor and promotion
Device；Bearing is arranged on the upper wall surface of tramcar；One end of body is rotatablely connected with bearing, and the other end of body is with being connect
Net-fault is in contact；One end of motor is provided with opening, and output section, the other end and rail of motor are provided with opening
The upper wall surface of electric car is connected；One end of pushing meanss is at least partly in opening, and be connected with output section, pushing meanss
The other end be connected with body；Wherein, motor drives axial movement of the pushing meanss in opening interior edge output section, so that
Body is separated or contacted with contact net.
In the technical scheme, first, bearing is arranged on the upper wall surface of tramcar；Secondly, by by body
One end is rotatablely connected with bearing, while the other end of body is in contact with contact net, so that contact net is powered for tramcar；
Because the height above sea level of contact net is different, and pot hole is uneven, therefore one end of body and bearing are rotatablely connected, and can be achieved
No matter the fluctuating on road surface and body contacts with contact net all the time, so as to improve the flexibility of body, to ensure contact net as rail
Electric car is powered；Again, one end of motor is set into opening, and output section is set in opening, meanwhile, by motor
The other end is connected with the upper wall surface of tramcar；Again, by the way that one end of pushing meanss at least partly is embedded in into opening, and
It is set to be connected with output section, meanwhile, the other end of pushing meanss is connected with body, promoted with realizing that motor drives
Device opening interior edge output section axial movement so that body is separated or contacted with contact net；When tramcar stops
In use, can be departed from body and contact net by such a structure, so that contact net stops being powered tramcar, keep away
Driver is exempted from manually to depart from body in the contact net the step of, has not only increased operating efficiency, reduce working strength, also improve
The security of driver, for the safety of driver provides guarantee.
In addition, the annular pantograph in above-mentioned technical proposal provided by the invention can also have following supplementary technology special
Sign：
In the above-mentioned technical solutions, it is preferable that pushing meanss include：Push rod and connects chain；One end of push rod is embedded in opening
It is interior, and be connected with output section；Connects chain is made up of the socket of at least two annulus, one end of connects chain and the other end phase of push rod
Connection, the other end of connects chain are connected with body.
In the technical scheme, first, by the way that one end of push rod is embedded in opening, and it is set to be connected with output section,
Then, one end of connects chain for forming will be socketed by least two annulus with the other end of push rod to be connected, and by connects chain
The other end is connected with body, and to realize when push rod is retracted into opening, push rod pulls on body and contact net by connects chain
Separation.Meanwhile when push rod stretches out out of opening, body contacts because of the not pulling force of drawn stem with contact net, due to connects chain
It is made up of the socket of at least two annulus, now connects chain is because of gravity fall；When body produces rotation because of the fluctuating on road surface, this
Body pulls on connects chain and tightens or fall, and without acting power to push rod, avoids the rigid contact between body and push rod,
Damage is produced because mutually pulling with push rod so as to avoid body, and is also assured when tramcar travels, annular is by electricity
Bow is in contact with contact net all the time, and then ensures the normally travel of tramcar.
In the above-mentioned technical solutions, it is preferable that annular pantograph also includes：Isolating device；Isolating device is insulator, every
One end from device is connected with body, and the other end of isolating device is connected with the other end of connects chain.
In the technical scheme, by the way that one end of isolating device is connected with body, and by the other end of isolating device
It is connected with the other end of connects chain, wherein isolating device is insulator, to avoid the electricity stream that body is drawn by contact net
To motor, so as to avoid motor from being damaged because the electric current flowed through is excessive, and then extend the service life of product.
In the above-mentioned technical solutions, it is preferable that annular pantograph also includes：Rotating part, fixed plate and connector；Rotating part
One end be connected with motor, the other end of rotating part is provided with otch；One end of fixed plate is fixed on tramcar
On upper wall surface, in the other end insertion otch of fixed plate；Connector sequentially passes through rotating part and fixed plate, so that rotating part is with consolidating
Fixed board is rotatablely connected.
In the technical scheme, first, one end of rotating part is connected with motor, and in the other end of rotating part
Otch is set；Secondly, one end of fixed plate is fixed on the upper wall surface of tramcar, and the other end insertion of fixed plate is cut
In mouthful；Secondly, by the way that connector is sequentially passed through into rotating part and fixed plate, so that rotating part is rotatablely connected with fixed plate, so as to
The flexibility of motor is improved, to increase the scope of activities of motor, is avoided because the scope of activities of motor is too small,
And cause to produce excessive active force between push rod and body, cause the situation that both are damaged to occur, and then extend product
Service life, reduce the use cost of product.
In the above-mentioned technical solutions, it is preferable that motor is insulated motor.
In the technical scheme, because motor is insulated motor, it further avoid what body was drawn by contact net
Electricity flows to motor, so as to avoid motor from being damaged because the electric current flowed through is excessive, and then extends making for product
Use the time limit.
In the above-mentioned technical solutions, it is preferable that body includes：Contact site and fixed part；Contact site is in sector, fan-shaped circle
