Integrated asphalt heating unit and comb
View Patent ↗An integrated heating and comb unit and method of mechanized asphalt raking in which a mechanized asphalt comb comprised of a rake attachment and an arm is attached to an engineering vehicle via a terminating end of the arm. The engineering vehicle can control and manipulate the mechanized asphalt comb into a raised inactive position, a lowered active position, and a plurality of positions between the raised inactive position and the lowered active position. When in the lowered active position, the mechanized asphalt comb applies a fixed downward pressure and depth of penetration to the applied surface.
1. An integrated asphalt heating and comb unit, the unit comprising:
a heating pan, said pan providing heat from a downward side of said pan; and
a plurality of teeth extending from said downward side in a downward orientation;
wherein said integrated asphalt heating and comb unit is attached to an engineering vehicle such that said engineering vehicle can control and manipulate said integrated unit into a raised inactive position and a lowered active position; and
wherein, when in said lowered active position, said integrated asphalt heating and comb unit applies a fixed downward pressure and depth of penetration to a surface.
2. The unit of claim 1 wherein said teeth are attached to a frame surrounding said heating pan.
3. The unit of claim 1 wherein said teeth are attached to a floating frame moveable relative to said pan and said floating frame is arranged below said downward side of said pan.
4. The unit of claim 1 , wherein at least one of said plurality of teeth is removable from said unit.
5. The unit of claim 1 further comprising: a wing support extending from said heating pan.
6. The unit of claim 5 wherein said wing support supports a propane cylinder which provides energy for at least part of said heat.
7. The unit of claim 5 wherein said wing support supports a battery which provides energy for at least part of said heat.
8. The unit of claim 7 wherein said wing support supports a propane cylinder which provides energy for at least part of said heat.
9. The unit of claim 8 further comprising at least two wing supports.
10. The unit of claim 9 further comprising a rail connecting said at least two wing supports.
11. The unit of claim 10 wherein said rail includes a control panel.
12. The unit of claim 10 wherein said rail includes a hydraulic motor.
13. The unit of claim 1 further comprising a hydraulic motor.
14. The unit of claim 1 further comprising a control panel.
15. The unit of claim 1 wherein, when said integrated asphalt heating and comb unit is used to heat asphalt, said integrated asphalt heating and comb unit is in a position between said raised inactive position and said lowered active position.
16. A mechanized method for removing and applying asphalt during an asphalt repair, the method comprising:
obtaining an integrated asphalt heating and comb unit, said unit comprising:
a heating pan, said pan providing heat from a first side of said pan; and
a plurality of teeth extending from said first side in a downward orientation;
attaching said unit to an engineering vehicle such that said engineering vehicle can control and manipulate said unit into a raised position, a lowered position, and an intermediate position between said raised position and said lowered position;
moving said engineering vehicle to an asphalt repair site with said unit in said raised position;
positioning said unit in said intermediate position;
utilizing said heating pan to heat asphalt in said asphalt repair site with said unit in said intermediate position;
without moving said engineering vehicle, positioning said unit in said lowered position where said teeth apply a fixed downward pressure and depth of penetration to a surface; and
scarifying said asphalt in said asphalt repair site with said teeth while said unit is in said lowered position.
17. The mechanized method of claim 16 , the method further comprising:
not moving said engineering vehicle while scarifying said asphalt in said asphalt repair site.
18. The mechanized method of claim 16 , the method further comprising:
moving said engineering vehicle to scarify said asphalt in said asphalt repair site.
19. The mechanized method of claim 16 , the method further comprising:
prior to said heating being completed, positioning said unit in an additional position where said teeth apply a fixed downward pressure to said surface; and
scarifying said surface.
20. A mechanized method for removing and applying asphalt during an asphalt repair, the method comprising:
obtaining an integrated asphalt heating and comb unit, said unit comprising:
a heating pan, said pan providing heat from a first side of said pan; and
a plurality of teeth extending from said first side in a downward orientation;
attaching said unit to an engineering vehicle such that said engineering vehicle can control and manipulate said unit into a raised position and a lowered position;
moving said engineering vehicle to an asphalt repair site with said unit in said raised position;
positioning said unit in said lowered position where said teeth apply a fixed downward pressure and depth of penetration to a surface;
utilizing said heating pan to heat asphalt in said asphalt repair site with said unit in said lowered position; and
scarifying said asphalt in said asphalt repair site with said teeth while said unit is in said lowered position.
