Description
Technical field
The present invention relates to a kind of endless-track vehicle Zhi Chongji structures, belong to endless-track vehicle walking mechanism technical field.
Background technology
Domestic wind-power market is by fast development in recent years, and the wind energy resources in the preferable Plain region of construction condition is almost
The wind energy totally, developed at present has been developed gradually to the more difficult mountain area of construction condition and marine transfer, causes cost of erection therewith
When the river rises the boat goes up, and how controlled investment expense becomes the important process of each construction unit.Wind power plant Road construction cost is made
For the important component of mountain area wind power plant architectural engineering investment, the object that Construction Party controls by every possible means is also become naturally.
As design side, how road is designed, could both ensure equipment conveying safety, and can makes quantities minimum, turned into
The primary and foremost purpose of design side.Mountain area wind power plant road construction is the indispensable link of Construction of Wind Power, because road is built in field
If being influenceed by mountain area wind-force size and mountain shape, so to focus on the ways and means of road line selection in terms of construction, together
When also to consider details, main points in highway layout and work progress in detail, to save construction cost and environmental protection resource.
Except the width and head fall of road, the important factor in order widened value and influence road engineering amount of turnaround section, this is just
Have to be taken into account equipment conveying vehicle vehicle commander and its means of transportation.
Due to exclusively for transport wind power equipment design special-purpose vehicle wheelbase it is larger, so turnaround section road widen value compared with
Greatly, and wheeled vehicle climbing capacity it is weaker, at the bigger abrupt slope of climbable gradient, generally require the traction of other vehicles.
But theoretically, tracked carrier is better than wheeled vehicle in these two aspects.
However, existing endless-track vehicle, tank and armoured carrier pursue the cross-country ability such as speed and effectiveness in vibration suppression, it is propped up
Roller is independent suspension, and it is very big with respect to the impulse stroke that car body moves up and down.If copy tank, armoured carrier
The special-purpose vehicle of Zhi Chongji structures design transport wind power equipment, because the tower of wind power equipment, cabin are too heavy, its hitch certainly will
Extremely huge, cost is high；In addition, heavy duty during transport is differed greatly with underloading when returning, effectiveness in vibration suppression is bad.
And the Zhi Chongji structures of the endless-track vehicle such as in general crawler-mounted excavator, bull-dozer, tractor, transport vehicle, piling machine,
Its thrust wheel is not independent suspension, and is integrally fixed at linear rigid track frame vehicle frame both sides, integral with vehicle frame（Or
Claim track beam）Lower section, thrust wheel can not opposing tracks frame move up and down, thrust wheel directly contacts with the caterpillar chain rail of ground connection,
And rolled on chain rail.The gravity that such structure type, vehicle gravity in itself and vehicle bear thing is by vehicle frame both sides
Track frame, pass to thrust wheel through supporting wheel shaft and supporting wheel bearing, then the caterpillar chain being in contact with it is passed to by thrust wheel
Rail, finally pass to ground via creeper tread.
The Zhi Chongji structures of this structure type, as tracked carrier, on rugged and rough and harder road surface road
During traveling, the load that its each thrust wheel is born is extremely uneven, for example, when vehicle is travelling on the road surface of concave shape, car
Both sides, only former and later two thrust wheels of track frame bear the gravity of whole endless-track vehicle and vehicle bears the gravity of thing, Zhi Chong
Wheel bearing is to be rotated in the case where bearing load relative to supporting wheel shaft；If the driving wheel and inducer that are installed on track frame
Installation site it is relatively low, it is almost concordant with thrust wheel below if, then driving wheel and inducer bear load；And when vehicle exists
When being travelled on the road surface of upper convex, one or two of thrust wheel that vehicle both sides only have in the middle part of track frame bears load.Due to working as vehicle
When being travelled on rough road surface, vehicle both sides respectively have one or two of thrust wheel to bear load, so load is excessively concentrated, by
Power components ' load is excessive.Actual use situation is that the contact stress of thrust wheel and chain rail is too big, and supporting wheel bearing is to hold
Rotated in the case of by very big load relative to supporting wheel shaft, so, thrust wheel, chain rail and supporting wheel bearing are easy to damage.
Further, since the situation of load is born often in only indivedual thrust wheels, so actual ground pressure is not
Average value, but completely unascertainable point-like concentrated force, when vehicle bear thing it is very heavy when, such concentrated force be easy to by
Creeper tread is bent；And when being turned on rugged road, it is hanging due to having multiple thrust wheels, so in steering procedure
In or after the completion of, crawler belt and thrust wheel transverse direction serious dislocation if continuing to travel, when thrust wheel falls, then occur " gnawing rail "
Phenomenon, have a strong impact on the service life of crawler belt.
That is, existing endless-track vehicle Zhi Chongji structures, it is suitable only for light weight and bears that thing is relatively light, ground pressure
It is smaller, and road surface is very flat or road surface is softer, the endless-track vehicle that seldom travels slowly travels on road.
Therefore, develop a kind of tower, cabin, blade that can deliver wind-powered electricity generation etc., the gradient it is larger compared with rigid pavement with compared with
The tracked carrier of fast speed traveling is wind-powered electricity generation carrier urgent problem to be solved.
Recent years, although there are several producers to develop tracked carrier exclusively for wind-powered electricity generation transport, transport can be used as
Car, tractor or trailer use, but because its branch heavy-duty machine structure still uses traditional structure type, the traveling of tracked carrier
Speed is very low, and when vehicle is travelling on harder road surface, vibration is very serious, and crawler belt service life is very short.
Also transported on the market without a kind of crawler belt that can bear larger weight fast running on rough road at present
Defeated vehicle.Therefore, a kind of Zhi Chongji structures of endless-track vehicle are developed, it is travelled when endless-track vehicle on rough road
When, each branch of supporting body deadweight and weight bearing rolls assembly again to be swung up and down with the fluctuating on road surface, automatic uniform
Ground distributes the load that each branch is held again, and branch rolls assembly and do not derailed again, is not in " gnawing rail " phenomenon, and Zhi Chongji structures are without as existing
As having device, the bearing being easily damaged is relatively rotated in the case where bearing heavy load, so as to increase substantially creeper truck
Travel speed and crawler belt service life, just turn into this area engineers and technicians be badly in need of solve key technical problem.
The content of the invention
The present invention proposes that its purpose is just to provide a kind of endless-track vehicle Zhi Chongji structures and shoe to solve the above problems
Band vehicle, endless-track vehicle Zhi Chongji structures make endless-track vehicle when being travelled on rough road, supporting body deadweight and the back of the body
Each branch of loading weight rolls assembly and can swung up and down with the fluctuating on road surface again, each branch can be made to roll assembly stress again more equal
Even, branch rolls assembly and is pressed in all the time on chain rail again, is not in derailing and " gnawing rail " phenomenon, and Zhi Chongji structures are not as existing dress
The bearing being easily damaged that is such, being relatively rotated in the case where bearing heavy load is put, so as to which creeper truck be significantly increased
Travel speed and crawler belt service life.
To achieve the above object, the technical solution adopted by the present invention is：A kind of endless-track vehicle Zhi Chongji structures, including equalizer bar
Assembly is rolled again with branch, and the cardinal extremity positioned at middle part of the equalizer bar is hinged on the track frame of endless-track vehicle, and its both sides has
Zhi Chongduan, the branch rolls assembly again, and hinged each branch in the equalizer bar is held again respectively, and passes through the swing of the equalizer bar
And can move up and down, the branch rolls assembly again carries out and is carried out again wound on the branch with disk roller loop chain, disk roller loop chain again including branch
On, and be pressed on caterpillar chain rail below.
The branch is carried out again is provided with the closed loop tracks that cross sectional shape is ladder type for strip, periphery, and coercive mechanism is located at its length
Spend the centre in direction；The rolling axle both ends that the disk roller loop chain is connected adjacent roller wheel unit by carrier bar form closed loop chain, the roller

60 cardinal extremity 60-1 is hinged on track frame 10, and two Zhi Chongduan 60-2 of the lower section of equalizer bar 60 are additionally provided with for being hinged Zhi Chong
The branch for rolling assembly 90 rolls assembly hinge hole 61 ' again, and two branch roll again assembly hinge hole 61 ' in horizontal direction flat
The distance A that Heng Liang is hinged pin-and-hole 11 " front and rear, pin-and-hole 11 is hinged to equalizer bar " is equal.
Gained knowledge and understood according to rational mechanics static(al), " acted on when the cardinal extremity 60-1 of equalizer bar 60 equalizer bar is hinged pin-and-hole 11
When having downward power W, if equalizer bar 60 holds 60-2 two branch to roll assembly hinge hole 61 ' again, in horizontal direction again
Be hinged pin-and-hole 11 in equalizer bar " before and after, pin-and-hole 11 is hinged to equalizer bar " distance A it is equal, then hold again suffered by 60-2 for two
Power F it is equal, equalizer bar 60 keep Fig. 6（a）Shown state.But if two are held 60-2 branch to roll assembly hinge again again
It is unequal to connect the suffered upward power in hole 61 ', then equalizer bar 60 will be swung around equalizer bar cardinal extremity bearing pin 11.
Such as Fig. 6（c）Shown, triangle LMN is planar moved, and point L can only be moved up and down, and point N horizontal can only be moved
Dynamic, then when point M has moved up distance H, triangle LMN moves to broken line triangle L ' M ' N ' position.By geometrical relationship
Understand, if Z=0, h=H/2, if Z ≠ 0, h ＜ H/2.
This explanation when equalizer bar 60 two hold again 60-2 branch roll again the suffered power of assembly hinge hole 61 ' it is unbalanced when,
Then equalizer bar 60 will be swung around equalizer bar cardinal extremity bearing pin 11, if one of branch rolls assembly hinge hole 61 ' again, height is kept
Constant, then equalizer bar cardinal extremity bearing pin 11 rises（Decline）Height be less than another and roll assembly hinge hole 61 ' again and rise（Under

Such structure, branch carries out 70 and can carry out axle 61 again around branch again to be swung freely, if moreover, be applied to branch carry out again axle 61 to
Under concentrated force T, then generally, such as Fig. 7（a）Shown, it is uniform that branch carries out the 70 upward support reactions born again.But
If the support reaction that branch carries out 70 lower sections is not uniform again, for example, when branch carry out again 70 midpoint to front X points support reaction greatly
Words, then branch carries out 70 and carries out axle 61 again around branch again swings along clockwise direction；Conversely, if branch carries out 70 midpoint to the branch of rear Y points again
If counter-force is big, then branch carries out 70 and carries out axle 61 again around branch again swings in the counterclockwise direction.
Such as Fig. 7（c）It is shown, it is similar with the characteristics of motion for analyzing equalizer bar 60, if represent branch carry out the point S of axle 61 again can only
Move up and down, and point Y can only be moved horizontally, then when point X has moved up distance H ', be moved to X ' from X points, Y points are moved to Y '
Point, S points are moved to S ' points, then distance h ' ＜ H '/2 that S is moved up.
When the support reaction that branch carries out 70 lower sections is unbalanced again, branch carries out 70 and will carry out axle 61 again around branch again to be swung this explanation, if
Branch carries out the side of 70 lower sections again（At X or Y points）Height keep it is constant, then branch is carried out axle 61 and risen again（Decline）Height be less than it is another
Side（At Y or X points）Rise（Decline）The half of height.
Such as Fig. 8（a）, Fig. 8（b）, Fig. 8（c）Shown, disk roller loop chain 80 includes disk roller unit 81 and carrier bar 71.Disk roller unit
81 mainly fix push and block 75 by disk roller 72, rolling axle 73, bearing 78, sealing ring 79, end cap 77 and shaft end is formed.Disk roller 72 is by pacifying
Bearing 78 mounted in both ends is supported on rolling axle 73, and carries out axial restraint by end cap 77, and therefore, disk roller 72 can be around rolling axle
73 rotate.The both ends of carrier bar 71 are respectively provided with a hole, and aperture is suitable with the diameter of axle of the both ends of rolling axle 73 installation carrier bar 71, and shaft end is solid
Push and block 75 are determined by the overlapping both ends for being fixed on rolling axle 73 of two carrier bars 71, and carrier bar 71 can rotate around rolling axle 73；When with chain
When the other end of plate 71 is connected with the rolling axle 73 of adjacent disk roller unit 81, multiple disk roller units 81 can be connected into one
Closed loop, form disk roller loop chain 80.Such structure, disk roller 72 can be around the respective flexible rotatings of rolling axle 73, and adjacent roller
Wheel unit 81 can rotate around its rolling axle 73.That is, such disk roller loop chain 80 is flexible in its longitudinal direction,
A flexible closed loop can be formed.
Such as Fig. 8（c）Shown, tubular is made in disk roller 72, and centre is the face of cylinder 82 for bearing load, its axial length ratio
The width for the periphery track 68 that branch is carried out on 70 again is slightly larger；Both ends are provided with the flange 76 of ring-type, circular conical surface 83 and cylinder on the inside of it
Face 82 is connected, and circular conical surface 83 outward angle in both sides is slightly more than the inclined-plane 69 that branch carries out the both sides of 70 periphery track 68 again
Angle.
Such as Fig. 9（a）, Fig. 9（b）It is shown, when disk roller loop chain 80, which is looped around branch, to be carried out on 70 periphery again, among disk roller 72
The groove formed by the circular conical surface 83 and the face of cylinder 82 of the flange 76 of both sides can just be stuck in the track 68 that branch carries out 70 peripheries again
On, when disk roller 72 carries out the rolling of track 68 of 70 peripheries along branch again, whole disk roller loop chain 80 can carry out 70 cycle rotations again around branch.
As shown in Figure 4, Figure 5, when the endless-track vehicle Zhi Chongji structures 1 of the present invention are hinged in vehicle frame with equalizer bar cardinal extremity bearing pin 11
When on the track frame 10 of 7 both sides, be looped around branch carry out again on 70, underlying each disk roller 72 groove be just stuck in ground connection carry out
On chain rail 41 with 40.70 are carried out again due to branch to be supported on the chain rail 41 of crawler belt 40 by disk roller 72, so, the branch from ground
Counter-force is to be directly passed to branch by disk roller 72 by the chain rail 41 of crawler belt 40 to carry out 70 again, does not have shaft strength in structure（Roller
Disk roller 72 is only lifted in carrier bar 71, is returned to branch carries out 70 top again when and bears disk roller 72 by bearing 78 in wheel unit 81
The deadweight of itself）.The track 68 that the cross section of the chain rail 41 of crawler belt 40 carries out 70 peripheries with branch again is essentially identical.In endless-track vehicle row
When sailing, disk roller 72 can roll along chain rail 41, and branch is carried out 70 and moved along a straight line along chain rail 41 again.
As shown in Figure 4, Figure 5, if road surface is flat, because two branch roll assembly hinge hole 61 ', in level side again
Be hinged pin-and-hole 11 in equalizer bar upwards " before and after, and to equalizer bar be hinged pin-and-hole 11 " distance A it is equal, so, track frame 10
The concentrated force of equalizer bar 60 is passed to by equalizer bar cardinal extremity bearing pin 11, axle 61 is carried out again by branch and passes to two be hinged with it
It is equal that 70, and two power that shoe 70 is born again are carried out again.70 length directions are carried out again because branch carries out axle 61 and is arranged on branch again again
Centre, and branch carries out 70 and can carry out axle 61 again around branch and flexibly swings again, therefore, two carry out again 70 born come from each disk roller 72
Support reaction be uniform on the length direction that branch carries out 70 again.That is, two are carried out 70 and are applied to by each disk roller 72 again
The power of the chain rail 41 of crawler belt 40 is uniform.It can thus be stated that the gravitation energy that vehicle gravity in itself and vehicle bear thing passes through
The track frame 10 of the both sides of vehicle frame 7, the equalizer bar 60 of the endless-track vehicle Zhi Chongji structures 1 through the present invention, branch carry out 70 and disk roller 72 again,
The chain rail 41 of the crawler belt 40 contacted with disk roller 72 is passed to evenly, so as to be delivered evenly to ground.
As shown in Figure 10, if road surface is not flat, such as there is a projection at the signified crawler belts 40 of arrow D, make this
The crawler belt 40 at place rises distance P, and now disk roller 72 signified arrow E is still pressed on the chain rail 41 of crawler belt 40, carries Zhi Chong
Carry out 70 rear end and roll small distance forwards, and branch signified arrow K is carried out axle 61 and is lifted up again, at the same time, puts down
Weighing apparatus beam 60 is swung around equalizer bar cardinal extremity bearing pin 11, the branch at rear carry out again 70 carry by the disk roller 72 of lower section move forward it is small
Distance, and equalizer bar cardinal extremity bearing pin 11 signified arrow C is lifted up.It can be seen from analysis above, M ＜ P/2, N ＜ M/2,
So N ＜ P/4.Because equalizer bar cardinal extremity bearing pin 11 is integrally fixed on the track frame 10 of vehicle frame 7, although this explanation ground is concavo-convex
Injustice, but the height that the Amplitude Ratio road surface of the dipping and heaving of vehicle frame 7 rises and falls is much smaller, and vibration reduces.
That is, the endless-track vehicle Zhi Chongji structures 1 of the present invention, can distribute to each shoe below by its uniform load
Band chain rail 41, and vehicle is during traveling, branch carry out again 70 and equalizer bar 60 swung with the dipping and heaving of landform, vehicle frame
7 up-down vibration amplitude greatly reduces, and illustrates the endless-track vehicle Zhi Chongji structures 1 of the present invention and has load uniform（Distribution）And vibration damping
Function.
Due to respectively installing an endless-track vehicle Zhi Chongji structure 1 of the invention before and after the track frame 10 of vehicle both sides, often
Individual branch carry out again 70 and equalizer bar 60 independently can be swung with the dipping and heaving of landform, and because branch carries out 70 front and back again
Smaller to length, so crawler belt 40 below can be bonded well with ground, and the load for being born each creeper tread is big
Cause identical.
In addition, as shown in figure 5, work as the cardinal extremity equalizer bar of the equalizer bar 60 of the endless-track vehicle Zhi Chongji structures 1 of the present invention
After cardinal extremity bearing pin 11 is arranged on the track frame 10 of vehicle frame 7, because two fixed covers 15,16 on track frame 10 limit balance
The opposing tracks frame 10 of beam 60 transverse shifting vertically, so when Vehicular turn, track frame 10 are swung laterally, equalizer bar 60 can be with
Track frame 10 is swung laterally together.Further, since the limitation of two split fixed covers 65,66 on equalizer bar 60, branch are carried out again
70 are unable to the transverse shifting of relative equilibrium beam 60, that is to say, that when endless-track vehicle turns to, branch carries out 70 again can be with track frame 10 1
Play horizontal swing.
Further, as shown in figure 5, carry out 70 lower section again in branch, track 68 that 70 periphery formed is carried out again from top card in branch
On the face of cylinder 82 by disk roller 72 and the circular conical surface 83 of the flange 76 of both sides in the groove that the top of disk roller 72 is formed, and carry out
It is stuck in from below in the groove that the lower section of disk roller 72 is formed with 40 chain rail 41, so, when branch carries out 70 transverse shifting again,
Branch carries out 70 again can drive the chain rail 41 of disk roller 72 and crawler belt 40 to move laterally together, so that the transverse shifting of crawler belt 40.
In the moving process, side force is from the fixed cover 15 or 16 of track frame 10, passes to equalizer bar 60, then by balancing
Fixed cover 65 or 66 on beam 60 passes to branch and carries out 70 again, carries out the side of 70 track 68 being below again by branch, push with
The circular conical surface 83 of flange 76 on its disk roller 72 contacted.Although disk roller 72 is by the side force of transverse shifting, due to disk roller
72 can't be to side-overturning by the downward pressure for carrying out 70 again from branch, disk roller 72.So as to which the opposite side on disk roller 72 is convex
The circular conical surface 83 of edge 76 pushes the side for the chain rail 41 being in contact with it, and side force is passed into crawler belt 40, makes crawler belt 40 relatively
Slide in face.
That is, the endless-track vehicle Zhi Chongji structures 1 of the present invention, including equalizer bar 60 and branch roll assembly 90 again, balance
The cardinal extremity 60-1 positioned at middle part of beam 60 is hinged on the track frame 10 of endless-track vehicle, and its both sides has Zhi Chongduan 60-2, Zhi Chong
Rolling assembly 90, hinged each branch in equalizer bar 60 holds 60-2 again respectively, and can be transported up and down by the swing of equalizer bar 60
It is dynamic；Branch rolls assembly 90 and carries out 70 and disk roller loop chain 80 again including branch again, and disk roller loop chain 80 is carried out on 70 again wound on branch, and is pressed in it
On the caterpillar chain rail 41 of lower section.It is strip that branch carries out 70 again, and it is trapezoidal closed loop tracks 68 that periphery, which is provided with cross sectional shape, hinged
Point is positioned at the centre of its length direction；The rolling axle both ends that disk roller loop chain 80 is connected adjacent roller wheel unit 81 by carrier bar 71 form and closed
Loop chain, disk roller unit 81 include disk roller 72, rolling axle 73, bearing 78, and disk roller 72 is cylindrical in shape, and axial both ends have flange 76, by
Bearing 78 installed in both ends is supported on rolling axle 73 and can rotated；Branch carries out 70 closed loop tracks 68 and caterpillar chain rail 41 again
At least a portion be stuck between the flange 76 of disk roller 72.
Because the endless-track vehicle Zhi Chongji structures 1 of the invention of this structure have load distribution function, even so
Travelled on rough road, each branch is carried out 70 and all the time can be compressed tightly against each disk roller 72 below below again
Caterpillar chain rail 41 on, and swung up and down with the fluctuating of landform, in the vertical direction without departing from chain rail 41.Due to branch
The track 68 and the chain rail 41 of crawler belt 40 carried out again on 70 are stuck between the flange 76 at the both ends of disk roller 72, it is impossible to are moved to both sides are relative
It is dynamic, so, the lateral resistance from ground is very big when turning to, and each branch carries out the disk roller 72 and chain rail 41 of 70 lower sections again
Be not in transversion malposition phenomenon, because disk roller 72 will not leave chain rail 41, so as existing endless-track vehicle will not occur
" gnawing rail " phenomenon, the service life of crawler belt can be greatly prolonged, moreover it is possible to improve the travel speed of endless-track vehicle.It is further, since each
Disk roller 72 all bears roughly the same load, and the diameter of disk roller 72 is big, so the contact stress of disk roller 72 and chain rail 41 is small,
This is also the key factor that can improve crawler belt service life.
The specific embodiment of the endless-track vehicle Zhi Chongji structures 1 of the present invention is set forth above, but not disobeyed actually
In the case of the core concept for carrying on the back the present invention, multiple structure types are can be devised by.
For example, in an embodiment of the present invention, tubular is made in disk roller, both ends are provided with flange, but can also be made middle convex
Rise its section to be trapezoidal and both ends be the face of cylinder shape, certain corresponding branch carries out the track of periphery and the chain rail of crawler belt again
Also corresponding change is made.
Carried out again in addition, the present invention can also be not provided with branch, but thrust wheel is directly set in the Zhi Chongduan of equalizer bar, so
Also there is certain effectiveness in vibration suppression.
Further, the present invention can also be not provided with disk roller loop chain, but thrust wheel is set in the lower section that branch is carried out again, its vibration damping effect
Fruit is suitable with embodiments of the invention, but so shaft strength of thrust wheel.
Endless-track vehicle Zhi Chongji structures provided by the present invention are described in detail above.It is used herein specifically individual
Example is set forth to the principle and embodiment of the present invention, and the explanation of above example is only intended to help to understand the present invention's
Method and its core concept.It should be pointed out that for those skilled in the art, the principle of the invention is not being departed from
On the premise of, some improvement and modification can also be carried out to the present invention, these improve and modified also in the claims in the present invention
Within protection domain.
