Definitions

• the present disclosure relates to an asphalt compactor, and more particularly, to a pneumatic tire compactor with a self-refilling water ballast system.
• Compactors or road rollers are construction vehicles used to compact soil or asphalt in the construction of roads. As they use the weight of the vehicle to compress the surface being rolled, the working parts for compacting are mostly steel drums. However, these steel drums can be replaced by pneumatic tires in certain designs. In road construction, pneumatic tire compactors are used to follow normal steel drum compactors to even the surface more smoothly and densely.
• ballast tank In case of a pneumatic tire compactor, the surface of the ground that tires made of rubber touch is very large, and the weight of pneumatic tires is much smaller than the steel drum. Therefore, installation of a ballast tank is generally needed in order to supplement the lacking weight.
• the ballast tank is generally installed under the operator platform of the body frame.
• the ballast tank can be filled with various kinds of heavy materials, such as water, sand, and steel scraps.
• water ballast is becoming more common as it is cheaper and environmentally friendly.
• users can occasionally empty the ballast since a lighter machine is easier to transport between work sites.
• Water ballast is also much easier to be emptied and refilled comparing with wet sand or steel scraps.
• FIG. 1 shows a part of a conventional pneumatic tire compactor with water ballast which must be refilled from an outside water source. This refilling process is performed manually through access panels 102a, 102b, 102c.
• Each of the two adjacent panels are connected by hinges 108-n, and the edges of the panel that is opposite to the edges having hinges 1 08-n are mounted on the upper rim of ballast tank 106 by bolts 110-n.
• bolts 110-n are removed and panels 102b, 102c should be rotated up along the hinges 108-n. Then, a hose is inserted underneath in order to refill ballast tank 106. This is very time-consuming and causes delays in work, resulting in lower productivity.
• a compactor which has a water ballast tank.
• An upper portion of the compactor's body frame is open.
• the ballast tank is installed inside the body frame, and the opened upper portion of the body frame is covered by a cover plate.
• the water ballast tank has a ballast drain port on the compactor's body frame.
• the ballast drain port is connected with the ballast tank by a ballast drain hose, and that is used to drain out some water from the ballast tank.
• ballast tank of the present disclosure is refilled with water falling onto the cover plate through the holes on the cover plate. Therefore, the refilling method of the present disclosure is completely environmentally friendly, economical and time saving.
• FIG. 1 is a perspective view of a conventional water ballast system of which the cover plate has three panels and hinges between each adjacent two panels;
• FIG. 2 is a side view of a compactor of which the water ballast system according to an embodiment of the present disclosure is installed under the cover plate;
• FIG. 3a and FIG. 3b are perspective views of part "A" in FIG. 2;
• FIG. 4 is a perspective view of a water ballast system according to another embodiment of the present disclosure of which the cover plate has a water inducing slope;
• FIG. 5 is a perspective view of a water ballast system according to yet another embodiment of the present disclosure of which the water ballast tank has a water level sensor;
• FIG. 2 shows a pneumatic tire compactor 200 in its entirety having a water ballast system according to an embodiment of the present disclosure.
• An upper portion of the compactor's body frame is open.
• a ballast tank 206 is installed inside the body frame, and the opened upper portion of the body frame is covered by a cover plate 204.
• the edges of cover plate 204 are placed on the upper rim of the body frame and joined to the frame by appropriate means such as bolts 216-n.
• ballast tank 206 is installed under cover plate 204.
• Cover plate 204 is disposed alongside a cabin plate 210 above the body frame.
• Cabin plate 210 is the plate on which a cabin 202 is mounted.
• Ballast tank 206 is filled with water.
• a drain hole 212 is formed on the side of ballast tank 206. Drain hole 212 is connected with a drain hose 214 and the other end of drain hose 214 is connected with a ballast drain port 208. Ballast drain port 208 is on the side of compactor 200's body frame. Drain hole 212 can be formed on any appropriate position of ballast tank 206 based on needs. Likewise, ballast drain port 208 can also be formed on any appropriate position of the body frame. It is preferable that ballast drain port 208 is on the lower side of compactor 200. Users can drain out ballast tank 206 by controlling ballast drain port 208.
• Ballast tank 206 is filled with water on site while working to achieve the desired weight. However, the lighter machine is easier to transport between work sites. Therefore, when transporting the machine to another site, users can drain water through ballast drain port 208 to empty ballast tank 206.
• FIG. 3a and FIG. 3b show same perspective views of part "A" in FIG. 2.
• Cover plate 204 has a plurality of holes 300-n. Holes 300-n are scattered on cover plate 204, so rainwater can be drained into ballast tank 206 through holes 300-n.
• the number of holes 300-n can be increased at the center location of cover plate 204, or holes 300-n can be only formed at the center location of cover plate 204. This is efficient since the natural vibration and the turns of the machine should allow any collected water to drain into ballast tank 206. Holes 300-n can also be used for drainage of any water used to clean the platform surface of the machine.
• cover plate 204 is made of a single plate. However, based on needs, cover plate 204 can be made of more than two panels.
• FIG. 3a shows cover plate 204 having two panels 304a and 304b. Panels 304a and 304b are connected by seamless joints 308-n. Seamless joints 308-n can have structure that the cross section of one panel's edge has a protrusion, and the other panel's edge has a receptor in the opposite direction. The two edge's cross sectional shapes are complementary so that they can be engaged each other.
• edges 302a, 302b, 302c, 302d, 302e, 302f all around cover plate 204 are angled upwards and raised so that water falling onto cover plate 204 is prevented from draining out over the edges of the machine.
• These raised edges of cover plate 204 are solid and tight enough to collect water near the edges without draining water out of the machine.
• the method of the present disclosure is good for the environment and natural. Also, there is no need to provide additional devices for manual refilling such as, hinges, water supply hoses, and storage tanks.
• FIG. 4 shows a water ballast system according to another embodiment of the present disclosure of which a cover plate 402 has a water inducing slope.
• the water inducing slope can be designed in various types based on the users' need.
• the inside periphery of the frame's upper rim has a protrusion running along itself.
• the protrusion can be formed into a slope-like structure inclined from opposite ending sides to middle side and the middle portion is flat.
• the edges of cover plate 402 are mounted on the protrusion.
• FIG. 4 shows cover plate 402 having three panels 404a, 404b and 404c. Panel 404a and panel 404b are mounted being inclined from both ending sides towards the middle portion. Panel 404c is supported by the middle portion of the protrusion. Holes 408a-n are intensively formed on middle panel 404c.
• cover plate 402 it is not necessary that the edges of cover plate 402 are angled upwards and raised since water falling onto cover plate 402 cannot drain out over the edges.
• FIG. 5 shows a water ballast system according to yet another embodiment of the present disclosure which has a water level sensor 502.
• Water level sensor 502 is installed inside of a ballast tank 500 at an appropriate height. When activated, water level sensor 502 sends a corresponding signal to the operation cabin so that users can drain water by opening ballast drain port 208 (shown in FIG. 2).
• the position of water level sensor 502 can be appropriately decided based on needs. For example, if the machine is used to work on the inclined ground, it is easy for the machine to be inclined. If that happens, the water on ballast tank 500 leans to one side so that water can overflow and spill out naturally. Therefore, the water volume of ballast tank 500 has to be under a set volume that is smaller than full volume of ballast tank 500. Accordingly, it is preferred that water level sensor 502 is installed in the position that it can be activated before ballast tank 500 is fully filled.
• the self-refilled water ballast is not limited to the pneumatic tire compactors as shown in the embodiments, but can be widely used for various construction machinery equipped with a ballast system.
