Embodiment
Embodiment one
The Universal base tread sweeping device basic structure of the present embodiment may refer to Fig. 3, including bottom is supported on base 1
On body 2, the top of body 2 has the tubular cylinder of built-in piston rod, and the overhanging end of piston rod is equipped with by grinding block support 4
Grinding block 3.In the present embodiment by taking 1 ° of base angular adjustment precision as an example, i.e. θ=1 °, then β is even number angle value, example convenient to carry out
Understanding.
The concrete structure of base is as shown in figure 4, the bearing 1-2 extended by bottom plate 1-1 and plate upper surface is constituted, bearing
Have on 1-2 hinge pin hole 1-J that the center of circle be A ', on the left of the hinge pin hole L apart from and be determining for B ' with the isometrical center of circle in hinge pin hole
Position pin-and-hole 1-D, and positioned at hinge pin hole opposite side and by the center of circle of hinge pin hole, radius for R toothed edge deep-slotted chip breaker 1-H.The saw
Tooth side deep-slotted chip breaker 1-H is shown in Fig. 4 with respect to the angular position size in hinge pin hole.
The bottom of body 2, which is extended on the forward and backward two clamping plates 2-1 matched with bearing 1-2 thickness, clamping plate, to be had and hinge pin hole
1-J positions correspondence and the equal center of circle of internal diameter be A hinge hole 2-J, the center of circle corresponding with toothed edge deep-slotted chip breaker 1-H positions be C
Pin shaft hole 2-H（The bearing pin aperture of front plate is more than rear plate）, and curved groove 2-D corresponding with dowel hole 1-D positions.
Inserting centring pin may be selected in hinge pin hole 1-J and hinge hole 2-J and dowel hole 1-D.Toothed edge deep-slotted chip breaker 1-
Each sawtooth of H both sides triangular tooth toothed edge has 2 ° of minute of angle with respect to the hinge pin hole 1-J centers of circle respectively.In toothed edge deep-slotted chip breaker
The compound bearing pin 5 of structure shown in load map 6, Fig. 7, the compound bearing pin 5 by respectively with large and small pin shaft hole phase on forward and backward two clamping plate
Large and small cylindrical section 5-1,5-1 matched somebody with somebody ', and the diamond-shaped cross-section section with the sawtooth matching of toothed edge deep-slotted chip breaker 1-H both sides toothed edge
5-2 is constituted.
The curve that curved groove 2-D width matches with centring pin diameter and center line is determined by equation below group：
；
；
；
In equation：
θ --- predetermined base angular adjustment precision, subsequently with 1 ° of example of value；
When B ' C --- base is around hinge pin hole rotation β angle, the length of dowel hole and pin shaft hole circle center line connecting；
L --- the distance of hinge pin hole and dowel hole；
R --- hinge pin hole to toothed edge arc groove center line distance；
β --- base is predefined for even number angle value around the anglec of rotation in hinge pin hole；
When α --- base is around hinge pin hole rotation β angle, the angle of dowel hole and pin shaft hole circle center line connecting and abscissa；
xB”--- using hinge pin hole as the abscissa of origin；
y B”--- using hinge pin hole as the ordinate of origin；
When B " C --- base is around hinge pin hole rotation β angle, dowel hole is counterclockwise around pin shaft hole with pin shaft hole circle center line connecting
Rotate the position behind θ=1 °.
By taking θ=1 ° as an example, now β is even number angle value, β -1 ° be odd number angle value, then above-mentioned equation group derivation
Referring to Fig. 8：When base angle requirement is β -1 °, it is necessary to by putting rotation β angle around hinge pin hole 1-J centers of circle A ', after in place
5 center of circle C dot inversions of compound bearing pin, 1 ° of realization.
Solid line is base first around the centring pin rotation β angle for being inserted into A ' points in Fig. 8（Even number angle）Afterwards, hinge pin hole 1-J, fixed
Position pin-and-hole 1-D and compound alignment pin geometric position state.Dotted line is extracts after the centring pin in hinge pin hole 1-J out in figure, bottom
Seat rotates the geometric position state after 1 ° further around compound alignment pin center of circle C points, and now base angle is β -1 °；The state lower bottom base
Dowel hole 1-D position B ' ' should just align matching with the deep-slotted chip breaker of body bottom portion, therefore be positioned according to conditions above is met
Pin-and-hole 1-D center of circle B ' ' track is the center curve that can determine that curved groove.
If base is around hinge pin hole rotation β angle, the angle of dowel hole and pin shaft hole circle center line connecting and abscissa is α, then
It can obtain following various according to geometric knowledges such as the cosine laws：
；
；
；
B ' ' point coordinate be：
；
According to current tread sweeping device pedestal angle use demand, base angle of regulation range is set as " -10 ° to+
30 ° ", then β is the even number angle value in -10 ° to+30 °, the boundary condition is substituted into, by above-mentioned various simultaneous solution, you can try to achieve
The movement locus of B ' ' points.The track is the curve of tread sweeping device body arc groove center.The body that processes accordingly with
Base engagement is that a base angle minimum adjustment amount can be achieved to have level adjustment for 1 °.
As shown in figure 9, when needing to realize that base angle least regulating amount is 2 ° when having level adjustment, as long as centring pin is inserted
In hinge pin hole and hinge hole, and relative rotation body and base using it as the center of circle, then the cylindrical section of compound bearing pin is inserted into pin
Axis hole, diamond are caught in the sawtooth breach of toothed edge deep-slotted chip breaker right position, then are locked.
As shown in Figure 10, when needing to carry out odd number angle adjustment, first carry out above step and be adjusted to immediate idol bigger than normal
Number Angle Position, then centring pin is extracted, rotating base is slightly reverse using compound bearing pin as the center of circle, centring pin is inserted through curved groove
In dowel hole, the curve characteristic of curved groove will ensure that counter-rotational angle is 1 °, so that the odd number angle needed for realizing is adjusted
It is whole.
The present embodiment uses simple cleverly structure to realize the minimum adjustment amount of base angle of tread sweeping device for 1 °
（Different θ angular configurations are set to realize remaining any minimum adjustment amount）Have level adjustable, it is clear not only to greatly increase tread
Sweeping device makes it have the versatility for being sufficient for being actually needed, and have enough to the adaptability of various bogies
Rigidity and intensity, it is safe and reliable, it is easy to adjust, significantly reduce research and development manufacture and maintenance cost.
In addition to the implementation, the utility model can also have other embodiment.For example, it is also possible to which the bottom of body is prolonged
Support plate is stretched out, and the forward and backward bearing clamping plate matched with branch plate thickness that base is extended by bottom plate and plate upper surface is constituted.Again
Such as, in addition to triangular tooth, toothed edge deep-slotted chip breaker both sides can also be stepped tooth, arc-shaped gear, and it is diamond-shaped cross-section that compound bearing pin, which is then removed,
Section is outer, can be with corresponding both sides are trapezoidal or section of arc convex.All use equivalent substitutions or equivalent transformation are formed
Technical scheme, all fall within the protection domain of the utility model requirement.
