[0011]

[Action]

 In this cylinder transporter, a trackless traveling device 22 such as a rubber crawler is used for traveling on steps, stairs, and level ground. The rotation output of the DC motor 16 is transmitted to the trackless traveling device 22 by changing the speed of the main clutch / brake lever 5 in three stages by the transmission 19 and adjusting the speed according to the traveling position. When driving on steps or stairs, the vehicle is operated at a low speed to climb and climb stably and safely.

When there are corners or curved sections in the transportation route, the side clutch lever 4 on one of the left and right sides is operated to disengage the clutch of the trackless traveling device 22 on that side, so that the machine body 35 moves in the required direction. Turn. In addition, the direction of the body 35 at the location where the cargo truck or the cylinder is installed is also changed.

At the installation location of the cylinder, the cylinder 1 is normally set up and stored. By pulling up the rotary handle 7, the hook metal fitting 23 and the receiving metal fitting 25 are disengaged from each other, so that the carrier 9 rotates upright around the rotary shaft 10 to a vertical state. Therefore, it is possible to easily mount the bomb 1 on the carrier 9 in a standing state.

The carrier support frame 11 is slid horizontally on the rail 12. The carrier support frame 11 is fixed to the rails 12 by the stoppers 13 at predetermined positions according to the purpose of running on a flat ground, running on steps or stairs, and loading and unloading cylinders. As a result, the center of gravity of the entire body moves to improve running stability.

[0015]

【Example】

 When traveling on level ground shown in FIG. 1, the stopper 13 of the carrier support frame 11 is inserted into the receiving hole 12b in the middle of the rail 12, and the center of gravity of the entire carrier is the contact surface of the track-type traveling device 22 of the rubber crawler type. It is inside and stable driving is possible. At this time, the carrier 9 is constrained to the carrier support frame 11 by the hook fitting 23 and the receiving fitting 25. The hook fitting 23 is connected to the rotary handle 7. The engagement holding spring 24 between the hook metal fitting 23 and the receiving metal fitting 25 is composed of a torsion spring. When the rotational force of the DC motor 16 is input to the transmission 19 by the V-belt 17 and the trackless traveling device 22 is driven by the sprocket 20 attached to the output shaft of the transmission 19, the carrier machine moves in the direction of the arrow in FIG. To run.

At the time of loading and unloading the cylinder shown in FIG. 3, the stopper 13 is inserted into the receiving hole 12c on the side close to the rotary shaft 10, that is, on the front side, and the carrier support frame 11 projects toward the front side of the carrier for a predetermined distance. It is fixed to the rail 12 in a closed state. When the rotating handle 7 is pulled up, the hook metal fitting 23 is detached from the receiving metal fitting 25, and the carrier 9 is rotated upright to a vertical state. In this state, the cylinder 1 is loaded on the carrier 9 and fixed to the carrier 9 with the band 8. When the rotating handle 7 is pulled down, the carrier 9 is again restrained by the carrier support frame 11.

At the time of traveling on the stairs shown in FIG. 4, the stopper 13 is inserted into the receiving hole 12a on the rear side, and the carrier support frame 11 is fixed to the rail 12 while being moved rearward. The position of the center of gravity of the entire carrier is within the ground of the trackless traveling device 22, which enables stable traveling even on a steep slope. Further, by shifting the shift lever 14 of the transmission 19 to run at an extremely low speed, highly efficient rotation can be obtained, and stable and safe lifting can be performed. Normally, backward movement (in the direction of the arrow in Fig. 4) is used for climbing up steps or stairs, but since the position of the center of gravity can be changed, it is possible to go up and down without selecting forward or backward movement.

As shown in FIG. 5, the stopper 13 is of a spring return type, and the wire 28 having one end fixed to the base end portion 32 of the stopper 13 is connected to the stopper operation lever 2 attached to the operation handle 6. ing. When the stopper 28 is pulled and the wire 28 is pulled, the tip of the stopper 13 is pulled out from the receiving holes 12a, 12b, 12c on the rail 12 side. When the hand is released from the stopper operating lever 2, the elastic force of the compression coil spring 33 causes the stopper 13 to slide back and be inserted into the receiving holes 12a, 12b, 12c.

[0019]

As described above, in the cylinder transporter of the present invention, since the DC motor 16 using the battery 21 as a power source is mounted on the machine body 35 as a driving means, there is little noise, and it is less crowded in a residential area or at night. But it can be operated and there is no danger of catching fire.

Rubber crawler type trackless traveling devices 22 such as rubber crawler type are installed on the left and right sides of the machine body 35 around the feet, and the rotation output of the DC motor 16 is transmitted to the trackless traveling device 22 via the transmission 19. It becomes possible to run at ultra-low speed with high efficiency rotation, and the stopper 13 is inserted into the receiving holes 12a, 12b, 12c of the rail 12 and the carrier supporting frame 11 is slid in the front-rear direction. Since it can move, it is possible to drive safely and stably even on a step or stairs.

The carrier 9 on which the cylinder 1 is mounted is connected to the carrier support frame 11 by the rotating shaft 10. When loading and unloading the cylinder, the hook metal fitting 23 and the receiving metal fitting 25 are disengaged from each other and the rotary handle 7 is used. Since the carrier 9 can be erected and rotated in the vertical state, it is possible to work with the cylinder 1 standing upright, and the unloading work of the cylinder is rationalized.

Further, in the cylinder transporter of the present invention, the side clutch lever 4 is operated to disengage the clutch of the trackless traveling device 22 on the left and right sides, so that the turning and direction changing operations can be easily performed without difficulty. ..
