Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, below in conjunction with the accompanying drawings and embodiment, it is right
The present invention is further elaborated.It should be appreciated that embodiment described herein is only used for explaining the present invention, rather than being used for
The limitation present invention.These accompanying drawings are simplified schematic diagram and only illustrate basic structure of the invention in a schematic way, therefore it only shows
Show the composition relevant with the present invention.
In the built-in brake 300 in the side of connection framework 2 in embodiment 1, at least including connecting hole 1, connection framework 2, inscription
Board 3, lock hole 4, steel wire rope 5, ears wedge clamp 6, main shaft 7, stop pin 8, steel wire rope 9, stabilizer 10 and wheel
Body 200 and brake 300 are constituted.
Steel wire rope 5 is fastened in the metallic channel of the great circle 201 of wheel body 200 in embodiment 1；One end of steel wire rope 9
Fix and be wrapped in the metallic channel of ringlet 202 of wheel body 4, the other end of steel wire rope 9 is winding successively after being connected with stabilizer 10
In the opposite side metallic channel of the ringlet 202 of wheel body 200.Contact line conducting wire (carrier cable and contact line) is in ambient temperature effect
Lower generation is expanded with heat and contract with cold, by ringlet 201 and the great circle 202 of wheel body 200 on steel wire rope 5 of wheel body 200 on steel wire rope 9
Synchronous operation, now steel wire rope 5 is sticked together with pendant by ears wedge clamp 6 and is connected, and falling mound can be compensated under various weather conditions
The tension variation that contact line conducting wire (carrier cable and contact line) causes, and ensure constant tension force.
In the built-in brake 300 in the side of connection framework 2 in embodiment 1, at least including internal tooth ratchet 301, lock pin holes
302, flywheel 303, ratchet 304, spindle hole 305, spring 306, fixing hole 307, fabrication hole 308, baffle plate 309 is constituted.

On inner side, at least provided with a pawl slot on the excircle of flywheel 303, the ratchet 304 is plugged in pawl slot, ratchet 304
It is provided between flywheel 303 and is ordered about on the spring 306 that ratchet 304 is contracted in pawl slot, the end of ratchet 304 and interior tooth papillae
The ratchet of wheel 301 is corresponding.
In the built-in brake 300 in the side of connection framework 2 in embodiment 1, when the brake 300 is in running order,
Flywheel 303 is fixedly connected with wheel body 200 with main shaft 7；When main shaft 7 is slowly rotated forward or backwards, due to there is spring 306
Effect, ratchet 304 abutted on flywheel 303, do not contacted with internal tooth ratchet 301, and the forward and reverse rotation of wheel body 200 is not influenceed.
In the built-in brake 300 in the side of connection framework 2 in embodiment 1, when carrier cable or contact line accident break, wheel
Body 200 loses because of wire (carrier cable and contact line) side and carries, described to accelerate when the moment of main shaft 7 in the case where pendant sticks together Action of Gravity Field,
Under the influence of centrifugal force, ratchet 304 overcomes the active force of spring 306, departs from the trench bottom of ratchet 304, rapidly with interior tooth papillae
The ratchet of wheel 301 is combined, and realizes that moment brakes.
In the built-in brake 300 in the side of connection framework 2 in embodiment 1, the brake 300 is compensated with existing ratchet and filled
The braking technology put is compared：The braking technology of existing ratchet compensating device is entirely using wire (carrier cable and contact line) broken string
Afterwards, ratchet loses and is loaded in pendant and sticks together free falling under Action of Gravity Field, and be engaged realization with the ratchet of supported underneath and brake.Its defect is to sting
The conjunction time is long, and braking distance is up to 200mm, if two crowns bump against, braking failure, braking success rate is low.The present embodiment 1
It is that the moment of wheel body 200 accelerates to rotate, and ratchet 304 is ejected and internal tooth ratchet 301 under the action of the centrifugal force after wheel body 200 loses and carries
Occlusion, its advantage is that wheel body 200 loses load post-acceleration greatly, and ratchet 304 is small with the gap of internal tooth ratchet 301, can be engaged with moment,
Braking time is short, and braking distance is less than 70mm.And ratchet 304 is that sector enters groove in internal tooth ratchet 301, in the absence of tooth
Sharp collision situation, braking success rate can reach 100%.
In the built-in brake 300 in the side of connection framework 2 in embodiment 1, the brake 300 is improvement pawl slot and spine
Force-bearing situation between pawl 304, is the arc surface for cooperating between the trench bottom of the ratchet 304 and the end of ratchet 304.
Ratchet 304 fly after again with 304 trough floor combination of ratchet when, the whole circular arc of the trench bottom of ratchet 304 and the end of ratchet 304
Face contacts simultaneously, greater impact power can be born, so as to be further ensured that the reliability that brake 300 is used.
In the built-in brake 300 in the side of connection framework 2 in embodiment 1, the brake 300 is for so that ratchet 304 exists
Initial and/or in the case of minor rotation, ratchet 304 can be abutted in reliably on flywheel 303, ratchet 304 and flywheel 303 it
Between be provided with and order about the spring 306 that ratchet 304 is contracted in pawl slot, the spring 306 is extension spring, it is also possible to be designed as stage clip
Or torsion spring.
