Abstract

PURPOSE: To rapidly, safely, and reliably support a cylinder unit on a side frame without protruding the cylinder unit from the side frame. CONSTITUTION: A support device for an on-vehicle cylinder unit is formed in such a manner that holes 13 and 13' for suspension are formed not only on the side of the case 12 of an on-vehicle cylinder unit 10 contained in a cylinder case 12 but also support members in such a state to support one or more cylinders 1-1 and 1-2 by support members 11 and 11', and hooks 17 and 17' at which the holes 13 and 13' for suspension are hooked are arranged at mounting members 15 and 15' fixed at the outside of a vehicle frame. The support members 11 and 11' or the cylinder case 12 is surely coupled to the mounting members 15 and 15' by means of bolts 22 and 24. This constitution supports the cylinder unit 10 without protruding the cylinder unit to a position above a side frame, and performs smooth spanning of a load-carrying platform on and between the frames, and rapidly, safely, and reliably supports the cylinder unit 10 on the frame.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support device for an on-vehicle cylinder unit.

[0002]

2. Description of the Related Art For example, in a vehicle powered by an engine using CNG (compressed natural gas) as a power source, as shown in FIG. 4, one or more large cylinders 1 for storing the CNG are housed in a cylinder case 2. Then cylinder unit 3, 3 '
However, in the conventional case, the two units 3 and 3 ′ are mounted on the side frame 4 of the vehicle.
4 ', in a state of being almost in contact with the outer surface of the frame 4,
The two units 3 and 3'are connected by two crossbars 5 so as to be suspended on 4 ', and fixedly mounted on the side frames 4 and 4'.

[0003]

However, in the means for suspending the cylinder units 3 and 3'on the side frames 4 and 4'as described above, the crossbar 5 is the side frame 4,
There is a problem in that the protrusions on the 4'may interfere with the mounting of the cargo bed or the like on the side frames 4, 4 '. The present invention has been devised as a problem to solve the above-mentioned problems, and a vehicle-mounted cylinder unit capable of supporting the cylinder unit on the side frame quickly, safely, and surely without protruding on the side frame. It is intended to provide a support device.

[0004]

In order to achieve the above object, the present invention provides a vehicle-mounted cylinder unit in which one or more cylinders are supported by a supporting member and accommodated in a cylinder case, and each support is provided on a side surface of the cylinder case. A suspension hole is formed together with the member, and a hook to which the suspension hole is attached is provided on an attachment member fixed to the outside of the vehicle frame so as to face the support member, and the support member or the cylinder case is attached to the attachment member by a bolt. The on-vehicle cylinder unit supporting device is characterized in that it is configured to be connected and fixed.

[0005]

[Operation] When the cylinder unit is supported by the in-vehicle cylinder unit supporting device of the present invention having the above-described structure, first, the suspension hole on the cylinder case side is hooked on the hook provided on the mounting member. Next, open the cylinder case, and screw the male screw on the rotating nut side of the long bolt described later to the nut fixed to the mounting member, and the other of the long bolts is connected to the support plate of the cylinder through the U-shaped piece described later. Fix on the upper side. Further, four short bolts are passed through the holes formed in the connecting metal fitting, which will be described later, of the mounting member through the holes formed in the cylinder case, and the nuts are fastened with the nuts at the ends.

[0006]

1 to 3, an embodiment of a supporting device for an on-vehicle cylinder unit according to the present invention will be described in detail. The same reference numerals as in FIG. In the unit, as shown in FIG. 1, the two support plates 11 are arranged so that the cylinders 1-1 and 1-2 are vertically stacked.
Insert holes 11a for the cylinders 1-1 and 1-2 opened in 11 ',
The cylinders 1-1 and 1-2 are housed in the cylinder case 12 with the cylinders 1-1 and 1-2 supported in parallel with each other. The support plates 11 and 11 'have a shape in which four sides are bent and the corners are cut off, and the insertion holes 11a and 11'a of the cylinders 1-1 and 1-2 are formed as described above. The cylinder case 1 facing each other at appropriate intervals
It is arranged in the inside of 2 and is fixed by welding or the like.

Reference numerals 13 and 13 'denote the support plates 11 and 11'.
2 are side holes 11b, 11'b of the cylinder and a side surface of the cylinder case 12 in contact therewith, and as shown in FIG. 2, one hole 13 has a trapezoidal shape and the lower end has a hook 1 described later.
Although it is wider than the width of 7, the upper end is the same as the width of the hook 17 to prevent movement of the cylinder unit 10 in the longitudinal direction of the cylinder unit, that is, the front-rear direction of the vehicle. The other suspension hole 13 'has a rectangular shape and is wider than the width of a hook 17' to be described later for easy hanging. In addition, 14 is the hole 1 for suspension.
It is a reinforcing rod fixed to the upper edges of 3, 13 'by welding or the like.

Reference numerals 15 and 15 'denote attachment members whose upper ends are fixed to the side frames 4 with bolts 16 and have a length substantially equal to the height of the cylinder case 12, and the suspension holes 13 and 13' near the upper ends. Hooks 17 and 17 'for hanging are provided, and the lower ends of the attachment members 15 and 15' are connected to the metal fittings 18 and 1 '.
Crossbars 19 and 19 'connected by 8' are connected to the lower ends of the mounting members on the side frame 4'side (not shown) across the lower sides of the side frames 4 and 4 '. A nut 20 is welded to the rear side of the hook 17 (17 ') near the upper ends of the mounting members 15 and 15', and the mounting member 15 (15 ') and the nut 20 are concentric with the nut 20, as shown in FIG. The cylinder case 12 has holes 15a (15'a) and 12a larger than the female thread of the nut 20. 2
A long bolt 2 is provided with screws at both ends, and rotating nuts 23, 23 'are fixed to the mounting members 15, 15' side. 24 is a short bolt and 25 is a nut.

When the cylinder unit 10 is supported by the supporting device for a vehicle-mounted cylinder unit of the present invention having the above-described structure, first, the suspension holes 13, 13 'on the cylinder case 12 side are provided with the hooks 17 provided in the mounting members 15, 15'. , 17 '. At this time, if the side close to the lower edge of the suspension holes 13 and 13 'is directed toward the tip side of the hooks 17 and 17', it is easy to hang, and after hanging, the upper edge of the trapezoidal suspension hole 13 and the hook 17 are hung. Fit together without a gap, and the movement of the cylinder unit 10 in the front-back direction is stopped. In addition, the hooks 17 and 17 'are reinforcement bars 14 fixed to the upper edges of the suspension holes 13 and 13'.
Since it abuts against, it can be engaged securely and withstand long-term use.

Next, the cylinder case 12 is opened, and the male screws of the rotation nuts 23 and 23 'of the long bolt 22 are attached as shown in FIG.
As shown in FIG. 3, the nut 20 is screwed to the nut 20 through the holes 12a and 15a (15′a),
23 'is rotated and fastened. Then, the other external thread of the long bolt 22 is inserted into the slit 26a of the U-shaped piece 26 fixed to the upper side of the support plates 11 and 11 ', and is inserted from both sides thereof by 2
Tighten two nuts 25 and fix to the U-shaped piece 26. Further, the four short bolts 24 are attached to the mounting member 15,
The nuts 25 are attached to the tips of the connecting fittings 18 and 18 'through the holes 18a and 18'a of the connecting metal fittings 15' to the holes 12b formed in the cylinder case 12 for fastening.
