Specific implementation mode
The present invention will be described in detail With reference to embodiment.
Electrified high-speed railway centenary design system is identical tension Compensation Design, and the terminal of each anchor section is arranged one
The anchor of compensation is all made of ratchet compensating device when design at present, compact-sized, and compensation efficiency is high and with braking
Function, product are more mature.
Electrification railway contact net also depends on the adaptability of train speed the tension and power supply capacity of conducting wire, and speed is got over
Height, tension is bigger, and when wire tension is more than 30kN, terminal anchor is unsatisfactory for technology requirement, it is therefore necessary to which design is a kind of
Heavy-load type ratchet compensating device.
In the busy circuit of cargo transport, in order to improve the efficiency of freight volume and the quick channel of handling, contact net may be designed as can
It is mobile.At moveable contact line rigid-flexibility transition terminal anchoring, contact line merges with carrier cable casts anchor, and output tension is at multiplication
Add.Common ratchet and compensation device cannot be satisfied requirement.In tunnel or at bridge, narrow space section, using common
Ratchet compensating device, flexible compensation amount is multiplied caused by contact net lines are swollen, cannot be satisfied range demands.Spirit of the invention
It is that can shorten stroke, bears heavy duty, brakes steadily, high reliability.
The present invention relates to a kind of contact line compensations to cast anchor with the perpendicular ratchet wheel compensating device of double wrap rope heavy duty, including perpendicular flute profile pair
Symmetrical wide ratchet ontology 1, transmission ratio 2（3）:1, symmetrical big wheel body winding starting compensation rope, rope is fixed double using symmetric form
Wedge clamp.Perpendicular wide 1 both sides of ratchet ontology of flute profile disymmetry are individually fixed in integrated connection and crank arm 2, and the integrated connection of both sides is bent
Arm 2 is fixed on L-type ratchet shaft supporting frame 3, and the integrated connections of both sides is cranked arm 2 passes through laterally straight bolt with L-type ratchet shaft supporting frame 3
It is fixed.L-type ratchet shaft supporting frame 3 is connect by stainless steel ratchet shaft 4 with ratchet fixing bracket, is freely rotatable.Stainless steel spine
Wheel shaft 4 is connect with L-type ratchet shaft supporting frame 3 using rolling bearing.
It is connected 2 both ends of cranking arm and is respectively provided with mounting hole, lower stomidium passes through large and small wheel body axis（Bolt axle）With perpendicular flute profile
The wide ratchet ontology 1 of disymmetry is fixed, and upper end hole is fixed by screw and L-type ratchet shaft supporting frame 3.
L-type ratchet shaft supporting frame 3 includes that vertical portion and top protrude horizontally up part, protrudes horizontally up part and whole connects
It connects to crank arm and 2 be fixedly connected, vertical portion is connect by stainless steel ratchet shaft 4 with ratchet fixing bracket.
3 bottom end of L-type ratchet shaft supporting frame is equipped with wide width wing braking tooth plate 5, and face erects the wide ratchet ontology 1 of flute profile disymmetry,
And it can adjust limit direction and gap.
Symmetrically the wide ratchet ontology 1 of perpendicular flute profile disymmetry uses aluminum alloy material, manufacturing process to use metal film low pressure casting
Technique.Integrated connection cranks arm 2 using carbon structural steels or low-alloy steel material, and manufacturing process uses cutting drilling technique.L-type spine
Take turns shaft supporting frame 3, wide width wing braking tooth plate 5 uses carbon structural steels or low-alloy steel material, L-type ratchet shaft supporting frame 3 and wide width wing
Brake the tube chamber welds with base connection of tooth plate 5.Stainless steel ratchet shaft 4 uses stainless steel.Rolling bearing material is for steel alloy or not
Become rusty steel.
The present invention has the function of to anchor, hangs, freely compensates, break braking, unloading etc., can be used for the contact of hightension system
Network termination casts anchor use especially suitable for high-speed railway hightension system, it can also be used to make at moveable contact line terminal anchoring
With.It is mainly used for contact net（Removable net）Contact line, carrier cable constant tension system compensate place of casting anchor entirely in system, particularly suitable
It is designed in hightension system, heavy load can be born, and there is high stable state braking function, braking time is short, flat, fast.Also it can be used
In other systems rope, at aerial cable Compensation Design terminal anchoring.
The present invention is with after triangle integrated connection arm insertion rolling bearing, and transmission efficiency is not less than 97%, the vibration of experiment
Number is not less than 2,000,000 times, and times of fatigue is not less than 500,000 times.
The also changeable structure of the present apparatus, be inversely proportional output, the proportional reduction of stroke, is suitable for stroke limiting section, especially
It is sound barrier basis limitation etc. on overpass.Shorten stroke, the increased length of falling mound quantity increases more than transmission ratio multiple
Length it is small.
For the ratchet ontology of the present apparatus using double group end face vertical tooth structures, brake plate can when breaking using lengthening tooth plate, failure
Effectively it is caught in tooth.Output is to be arranged symmetrically with input offset rope sheave slot, double-steel wire rope output and input, by contact net end
End anchor force reduces 1/2 at stabilizer, and the power for being distributed in wheel body is uniformly distributed, and wheel body is using symmetrical wide width wing, stability and can
It is higher by property, unstable phenomenon does not occur.
