Description

  The present invention relates to a road snow melting device for a forklift using engine waste heat, which is used for melting snow on a premises road using waste heat of a vehicle engine.

  Although it is difficult to remove snow from the forklift passage in the northern country office premises, if the snow melts, it becomes water and flows into the drainage drain, so it does not take much time, and the heat required for melting is the engine. Since it is waste heat, it is an ideal road cleaning method free of charge, and furthermore, forklifts frequently go back and forth on a fixed road and frequently give waste heat to the road surface. There is no type of road snow melting device.

  Even if a snow drain plate is attached to the forklift and snow is removed like a bulldozer, the snow must be transported with some space secured and placed as a snow mountain. The current situation is that we have a hard time.

Patent No. 3876427

  The problem to be solved is embodied as a snowmelt warp in Patent Document 1, but damage to the bottom surface occurs in the warp. Although snow continues to exist at the ski resort, the snowmelt sled melts the snow on the road and the snow disappears, so the bottom of the sled is in direct contact with the road surface, causing damage to the bottom of the sled and not durable. It is an object to provide a device having the characteristics.

  The present invention comprises a hot water tank that is heated by the heat of the engine coolant via a heat exchanger that contains hot water inside and contains the hot water, and an endless track that is heated by passing through the heated hot water. A snow melting device composed of a drive wheel, idler wheel, upper support wheel, and lower support wheel that drives the endless track and circulates around the water bath is attached to the bottom of the forklift, and the forklift travels. This is a forklift road snow melting device that uses engine waste heat to ground the endless track and melt snow on the road surface.

  According to such a configuration, if a low-speed vehicle such as a forklift uses an endless track, it will not interfere with the work travel, and the endless track is passed through a heat exchanger with the heat of the engine coolant. The endless track that has been heated is grounded to the passage continuously by running a vehicle equipped with this device, and the snow is melted by the heat capacity of the endless track itself. There is an effect that snow can be melted on a road by a durable device without using an inferior warp.

  According to the present invention, the endless track is driven to circulate around the hot water bath, pass through the hot water bath and warm, and then ground it to the road surface to melt the snow on the passage. Hot water is heated by a heat exchanger that uses engine waste heat built into the water bath. As a result, there is an advantage that the snow on the road surface is surely melted without using a sled having poor durability due to damage to the bottom surface.

  It is necessary to remove snow with a bulldozer at the start of work as usual, but as mentioned above, snowfall during daytime work is melted away by this snowmelter, reducing snow removal labor and costs and forking during snow removal work. There is an advantage that there is no loss of lift shutdown.

  For example, a snowfall of 24 cm per day is only 0.17 mm per minute. For example, if the forklift operation interval is 5 minutes, 0.85 mm of snow may be melted during each run. For example, if you run on a ski resort, a large amount of snow will adhere to the endless track and the bath will soon be filled with snow, but the present invention has the advantage that this does not happen.

  The use of a soil removal (snow) board to handle snow accumulation of about 1 mm per run of a forklift will prevent the board and road surface from being damaged because the bottom of the board will contact the road surface directly. Therefore, there is an advantage that the snow on the road surface is surely melted without using a soil removal (snow) plate having poor durability.

  In addition to the direct effect of melting the snow and removing it from the road surface, unlike mechanical snow removal, there is an advantage that the labor required for securing a snow dump and transporting the snow there is reduced.

  In addition, when snow is stepped and hardened with a tire, it becomes an ice plate from the pressure snow, and in this way, there is an advantage that the removal of the sherbet snow with a little melting of the snow is less difficult.

  The equipment installed on the bottom of the body of the forklift automatically melts snow on the aisle while working on the forklift as usual. There is an advantage that it is not necessary to temporarily stop and remove the snow in the passage, and it is not necessary to reduce the work efficiency just because it snowed.

FIG. 1 is an explanatory diagram of a forklift road snow melting device using engine waste heat using the endless track of claim 1. (Example 1).

  Instead of adopting parts that damage the bottom surface due to friction with the road surface, such as snow melting, an endless track that prevents damage due to friction by giving the same ground traveling speed as the traveling speed of the vehicle equipped with this device is adopted. By implementing a heat transfer method that transfers engine waste heat to the track without waste, the vehicle-mounted road snow melting method that uses free engine waste heat has been realized.

  In the first embodiment, an endless track is adopted as the snow melting component, and this is driven in synchronization with the running of the forklift to be grounded. A hot water bath is prepared that praises the hot water heated by the heat of the engine coolant via the built-in heat exchanger. The endless track is heated by passing the endless track through the hot water in the water bath with the upper support ring. Thus, the heated endless track is driven and grounded by the lower support wheel to melt the snow on the road surface. This snow melting device is attached to the bottom of the forklift to melt the snow on the road surface as the forklift runs.

  FIG. 1 is a cross-sectional view of an example of the embodiment of the device of the present invention, in which a water film is always formed between the heated endless track 1 and the accumulated snow 9 and the friction coefficient is Lower. Therefore, if the endless track is not driven, the endless track slides on the snow surface, so that the ground contact surface of the endless track is fixed. In this case, since the snow melting ability of the endless track is reduced, one endless track is driven by eight drive wheels in order to prevent this.

  In addition, by driving 8 drive wheels so that the ground traveling speed of 1 endless track matches that of the vehicle, slippage between 1 endless track and 10 road surfaces is eliminated and wear of 1 endless track is prevented. .

  2 idler wheels support the circumferential rotation of 1 endless track.

  Further, the upper support ring of 5 pushes down the 1 endless track below the level of 4 so that the 1 endless track passes through the hot water in the 3 hot water bath.

  Further, the lower support ring of 11 secures the snow melting action of the 1 endless track by pushing down the 1 endless track so that the 1 endless track is in close contact with the 9 snow cover of the 10 road surface.

  Further, a small hole may be provided on the ground contact surface of one endless track to ensure snow adhesion.

  The amount of hot water in the hot water bath 3 increases because the snow adhering to the endless track 1 is brought into the hot water bath 3 and melts. On the other hand, since there is hot water attached to the 1 endless track that goes out, the amount of hot water decreases, but the amount of subtracted hot water increases, so the hot water overflowing from the hot water bath falls into the passage and melts snow. The top does not cause heat loss and does not require hot water supply.

  Also, the hot water in the hot water tank 3 is heated by the heat of the engine coolant by the heat exchanger 6, and the hot water is cooled by heating the 1 endless track that has been cooled. Repeat this.

  The hot water in the hot water tank 3 is agitated by the 1 moving endless track to increase the efficiency of heat exchange.

  7 engine exhaust gas is blown onto the endless track and the endless track is heated by the heat it has to further increase the snow melting ability of the 1 endless track.

  The device installed on the bottom of the forklift body automatically melts the snow on the passageway while running the forklift as usual, so the melted snow flows into the drainage channel just like rain, and bothers It is not necessary to suspend the work and remove the snow in the passage, and it is not necessary to reduce the work efficiency just because it snowed.
