Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a turret truck using LP gas as a fuel.

(Prior Art) In a turret truck that uses LP gas as a fuel,
The gas pipe must be guided so that it will not be twisted or entangled in the swivel turret containing the engine mechanism and will not be pulled. As a measure to do this, it is conceivable to have the pipe run outside the side wall of the turret and lead it through the hole in the center of the upper wall of the turret.However, in this case, there is a risk that the pipe will bend or break due to a collision or other accident. Since it protrudes above the ring-shaped steering wheel, it is uncomfortable for the operator, and there are other problems such as impairing the appearance of the turret truck.

(Problems to be solved by the invention) The present invention has been made in view of the above-mentioned actual circumstances.
The gas pipes are routed under the floor of the cockpit, and are introduced into the turret regardless of the turning motion of the turret and connected to the engine, thereby eliminating the above-mentioned difficulties.

[Structure of the Invention] In order to achieve the above object, the turret truck of the present invention is equipped with a gas cylinder in the cockpit, and the turret that swivels on the fixed base by the operation of the ring-shaped handle is allowed to swivel around the bottom wall. A guide notch that substantially matches the range is provided, and a gas pipe in which a rubber pipe connected to the gas cylinder is inserted is formed from a gap formed by the lower end of the side wall of the turret and the guide notch via the underfloor of the cockpit. It is configured by being guided into the turret and keeping an interval with its inner wall, avoiding internal mechanisms such as the engine and connecting to the vaporizer above.

The guide notch provided around the bottom wall of the turret may be a guide slot instead of this, and in this case, the pipe is guided through the guide slot into the turret and pulled out vertically. With this, the space between the inner wall of the turret and the inner wall of the turret can be reliably maintained, and the vaporizer can be reached in the shortest distance, which is desirable from the viewpoint of material saving.

The engine mechanism can be either water-cooled or air-cooled, but it is an air-cooled engine, and a vaporizer connected to a gas pipe introduced into the turret is installed in the vicinity of the exhaust port for the cooling hot air, and the LP gas A mode in which vaporization is performed and the gas is sucked into the engine is desirable from the viewpoint of simplifying the mechanism and effectively utilizing the heat source.

(Embodiment) An embodiment will be described below with reference to the drawings. In FIGS. 1 to 3, reference numeral 1 denotes a turret track body, 2
Is the cockpit, 3 is the cockpit floor, and there is a gas cylinder 8 in one corner.
Equipped with. 4 is a fixed base 6 provided in front of the cockpit floor 3
A turret with a wheel-shaped handle 5 that swivels upward and has an air-cooled engine 7 inside.

The turret 4 is formed around the bottom wall of the turret 4.
The guide cutout portion 4a that substantially coincides with the turning allowable range of
A gas pipe 9 in which a rubber pipe 10 connected to the gas cylinder 8 is inserted is inserted below the floor through a through hole 3a provided in the floor 3 of the cockpit to extend to the floor just below the turret, and a through hole 11 provided in that portion. Further, it is pulled out to the floor again and guided to the inside of the turret 4 through the gap formed by the lower end of the side wall of the turret 4 and the guide notch 4a. 7
The air-cooled engine 7 is connected via a to a vaporizer 7b arranged in the vicinity of the hot air exhaust port (see also FIG. 6).

In the embodiment shown in FIGS. 4 and 5, the guide slot 4c is provided in the peripheral portion of the bottom wall of the turret 4 instead of the guide notch 4a, and the guide elongated hole 4c is substantially aligned with the turning allowable range of the turret. In the same manner as above, the gas pipe 9 passing through the underfloor of the cockpit is guided to the turret 4 through the guide elongated hole 4c, pulled out in the vertical direction as it is, and at a position above the hot air exhaust port of the air-cooled engine 7 through the filter 7a. It is connected to the vaporizer 7b arranged in.

[Advantageous effects of the invention] As described above, the present invention is configured so that the gas pipe is guided from below the turret into the turret through the underfloor of the cockpit. There was no problem with the machine, and the risk of pipe bending and damage due to collisions and other accidents was eliminated. The gas pipe introduced into the turret is connected to the upper vaporizer irrespective of the swirling motion by the play action of the guide notch or the elongated guide hole and the spacing between the swirling inner wall of the turret and the turret swirl. There is no risk of kinking, squeezing, or pulling due to. Of course, it does not spoil the appearance as a turret truck.

Further, in a mode in which the engine mechanism is an air-cooled engine, its cooling hot air (about 60 ° C.) is blown to the vaporizer and vaporizes the LP gas, so that heat exchange in the vaporizer is unnecessary as described above, The entire mechanism can be simplified, which is economically advantageous.
