Embodiments of the present invention will be described below with reference to the drawings. 1 is a top view of a cylinder fixed and attached state, FIG. 2 is a top view of a cylinder swivel take-out position, FIG. 3 is a side view of a cylinder rear portion replacement position, and FIG. 4 is a side view of FIG. In FIG. 1, the support frame 2 to which the fuel gas cylinder 13 is attached is fitted into a shaft 7 on the upper surface of the base 6, which is fixed to the suspension hole 12 on the upper surface of the counterweight 11 with a bolt 8, and rotates around the shaft 7. The movable rotating plate 1, the hinge 3, and the simple auxiliary device 4 are connected.
[0008]
FIG. 1 shows a cylinder fixed attachment state in which the cylinder 13 is fixedly attached to the counterweight 11. From the state where the handle 5 of the support frame 2 is gripped and the cylinder is fixedly attached as shown in FIG. 1, the rotating plate 1 and the support frame 2 are integrally rotated horizontally around the shaft 7 to the rear side, The state is moved to the removal position.
Then, as will be described later, the rotating plate 1 connected to the support frame 2 remains in the horizontal direction from the cylinder fixed mounting position shown in FIG. 1 as shown in FIG. The counterweight 11 is rotated to the rear side. As shown in FIGS. 1 and 2, the base 6 provided on the upper surface of the counterweight 11 is a substantially rectangular plate-like shape elongated in the width direction of the counterweight 11. A support shaft portion 6a is formed at one corner at the rear side of one side so as to extend in a direction perpendicular to the width direction of the counterweight 11. Accordingly, the rotating plate 1 connected to the support frame 2 is arranged in the rearward direction of the counterweight 11 in the horizontal direction around the shaft 7 attached to the support shaft portion 6a formed to extend in the direction perpendicular to the corners of the upper surface of the base 6. It will rotate. When the rotary plate 1 is rotated about the shaft 7 as a support shaft, the support frame 2 is vertically moved with respect to the rotary plate 2 via a hinge 3 on the rear side edge 1a of the rotary plate 1 serving as a rear side edge. Wear pivotally.
FIG. 2 shows this cylinder turning extraction position. Figure 3 looks at the cylinder pivot take-out position of Figure 2 showing the positional Shi out up pivoted cylinder turning in the horizontal direction from the side, with shows a diagram cylinder is in a horizontal state in phantom, the bomb turning extraction A state in which the support frame 2 is bent downward from the position around the hinge 3 of the rotating plate 1 is indicated by a virtual line. A state where the support frame 2 is bent downward is a cylinder rear portion replacement position where the cylinder 13 is replaced. The support frame 2 can be set from a horizontal state to a bent state by operating a handle 5 provided at a front end of the support frame 2 so as to be able to support a cylinder load so as to support the cylinder load. The band 9 for attaching the cylinder 13 is provided while being able to position in the state.
[0009]
Therefore, when the fuel gas cylinder 13 is replaced, the shaft 7 on the upper surface of the base 6 is integrated as shown in FIG. 2 , with the rotating plate 1 connected to the support frame 2 being integrated from the cylinder fixing attachment position shown in FIG. As shown in FIG. 3 , the support frame 2 is bent downward by the handle 5 around the shaft core of the hinge 3 . In addition, by lowering the cylinder 13 to the rear replacement position, it is possible to achieve a height at which the cylinder replacement operation can be easily performed.
In the above description, the support frame 2 can be bent downward by the handle 5 as shown in FIG. 3 after moving to the take-out position rotated to the rear side shown in FIG. This is because the hinge 3 is connected at the rear side edge 1a of the rotary plate 1 as shown in 2 and the cylinder 13 can be bent to the rear replacement position around the axis of the hinge 3 .
[0010]
The support frame 2 is lowered from the rotating plate 1 by bending at three hinges to bring it to the rear cylinder replacement position. At the rear cylinder replacement position, the cylinder 13 is replaced with a full tank, and then the support frame 2 is moved horizontally. Raise it . When returning to the take-out position by raising it horizontally, the support frame 2 to which the fuel gas cylinder 13 is attached is connected to the rotary plate 1 connected to the support frame 2 by the hinge 3 using the simple auxiliary device 4. Consideration is made so that the operator can easily return without receiving the weight directly by the action of the auxiliary device 4. As the simple auxiliary device 4, a simple labor-saving device such as a commercially available gas spring may be selected.
[0011]
After replacing the cylinder 13, it is sufficient to follow the procedure in reverse, and since the force of the simple auxiliary device 4 such as a gas spring is used, the cylinder 5 can be easily filled with the handle 5 of the support frame 2. 13 can be returned to the horizontal state, and then the support frame 2 may be rotated around the shaft 7 to the fixed mounting position.
[0012]
By using the bracket for the fuel gas cylinder according to the present invention, it is not necessary for the operator who replaces the cylinder to lift the heavy cylinder 13 to a high place forcibly, and even if a gas shortage suddenly occurs in a narrow passage. In addition to being easily exchangeable, the cylinder 13 can be arranged close to the driver's seat, so that it is easy to secure a rear view, which is very useful in terms of reducing worker fatigue and working safety.
