When the operator grips the gripping member 12 and pushes or pulls in the horizontal direction, the lifting device 6 is moved along the traveling rail 3 or the traversing rail 4, and the LP gas container holding device 13 described later is moved. It is possible to move above the LP gas container storage space 30 or the truck 31 stop position.

An LP gas container holding device 13 for holding the LP gas container 2 is detachably attached to the holding member 12. The LP gas container holding device 13 mainly includes a frame 14, a mounting member 15, a suspension member 17, an attachment 18, and the like. The frame 14 forms a skeleton of the LP gas container holding member 13 and is arranged in parallel with the traversing rail 4. At both ends in the longitudinal direction of the frame 14, mounting members 15 are attached. This mounting member 15
Is for detachably attaching the LP gas container holding device 13 to the lifting / lowering device 6, and is formed in a substantially J-shape in a front view. In addition, an LP is provided at a substantially central portion of the mounting member 15.

When a sensor for detecting whether or not the tip of the hanging member 7 is grounded on the floor 19 is attached to the tip of the hanging member 17, and the sensor determines that the tip of the hanging member 17 is grounded on the floor 19. Alternatively, the lowering operation by the lifting device 6 may be automatically stopped.

Attachments 18 are arranged at equal intervals in the longitudinal direction of the frame 14 and attached to the frame 14 via a support member 20. The attachments 18 are for locking and holding the handle portion 2 a of the LP gas container 2. In this embodiment, five attachments 18 are attached to the frame 14. Therefore, in the LP gas container transport device 1 according to the present embodiment,
Up to five LP gas containers 2 can be transported at a time. Here, the details of the attachment 18 of the LP gas container holding device 13 will be described with reference to FIG.

FIG. 2 is a partial front view of the LP gas container holding device 13. In FIG. 2, a part of the frame 14 is not shown. As shown in FIG.
, The supporting member 20 is rotatably supported while penetrating the frame 14. The support member 20 is for supporting the attachment 18 movably, and has a pair of annular members formed at one end (lower side in FIG. 2) of which are formed annularly and movably connected to each other. 20a. The attachment 18 is supported by the support member 20 configured as described above, so that the attachment 18 can freely move with respect to the frame 14. Therefore, as described later, when the handle portion 2a of the LP gas container 2 is locked by the lock arm 28 of the attachment 18, the direction of the handle portion 2a of the LP gas container 2 matches the direction of the lock arm 28. If not (see Figure 1),
By rotating the attachment 18 via the support member 20, the handle portion 2a of the LP gas container 2 can be locked by the locking arm 28. Furthermore, LP
Even when the gas container 2 is not disposed immediately below the attachment 18, the attachment 18 moves to the handle portion 2a of the LP gas container 2 by allowing the attachment 18 to move, and the handle portion 2a is locked by the locking arm 28. can do. Therefore, there is no need to previously perform the operation of aligning the LP gas containers 2 directly below each attachment 18 at equal intervals.

The attachment 18 comprises a telescopic member 21 formed to be extendable and contractable and a locking member 22 for locking and holding the handle portion 2a of the LP gas container 2. The elastic member 21 includes a pair of upper frame members 23 rotatably supported by the support member 20 and a pair of lower frame members 24 rotatably connected to a substrate member 25 of a locking member 22 described later.
Are rotatably connected to each other to form a substantially pantograph shape.

When the upper frame member 23 and the lower frame member 24 open and close in one direction, the upper and lower ends of the pantograph shape are brought close to each other, and the elastic member 21 is compressed in the vertical direction. With the compression of the elastic member 21, the locking member 22
Is moved upward. On the other hand, the upper frame member 23 and the lower frame member 2
When the leg 4 is opened and closed in the other direction, the upper and lower ends of the pantograph shape are separated, and the elastic member 21 is extended in the vertical direction. With the extension of the elastic member 21, the locking member 2
2 is moved upward. Here, the members of the support member 20, the upper frame member 23, the lower frame member 24, and the substrate member 25 are rotatably connected by a pivot shaft 26.

It should be noted that the pantograph shape described in claim 2 is not necessarily limited to an accurate rhombus, and for example, the upper frame member 23 and the lower frame member 24 may have different lengths. One of the pair of upper frame members 23 (or the lower frame member 24) may have a different length from the other. However, the length of the member here does not mean the maximum length from one end to the other end but the length between the pivot shafts 26 along each member.

Further, between the upper frame member 23 and the substrate member 25 of the locking member 22, two first tension springs 27 are attached by a pivot shaft 26. The first tension spring 27 urges the locking member 22 upward (the frame 14), and applies the upper frame member 23 in a direction in which the pantograph shape is compressed vertically by its elastic restoring force. Energize. By this biasing, the elastic member 21 is held in a vertically compressed state, and the locking member 22 is moved upward.

The height of the LP gas container 2 is slightly different (for example, about 4 cm) depending on the production year or the like, even if the container has the same capacity. Container 2 may be used in mixture. Even when the grip portions 2a of the LP gas container 2 having different heights are respectively held by the locking arms 28 described later, the locking arms 28 are moved in the vertical direction by expanding and contracting the elastic member 21 in the vertical direction. Since the handle portion 2a of the LP gas container 2 can be locked and held, the height of the locking arm 28 does not need to be finely adjusted for each LP gas container 2 by the lifting operation of the lifting device 6.

The spring constant of the first tension spring 27 of the telescopic member 21 is such that when the LP gas container 2 is lifted by the elevating device 6, the weight of the LP gas container 2 causes the telescopic member 21 to expand and contract in the vertical direction. It is set to be. Therefore, when the LP gas container 2 is placed at a predetermined position by the lowering operation of the lifting / lowering device 6, the expandable member 21 is compressed and deformed in the vertical direction, and the first tension spring 29 is moved by the elastic restoring force to cause the LP gas Absorb the shock applied to the container 2,
The LP gas container 2 can be safely placed.

The locking member 22 locks and holds the handle portion 2 a of the LP gas container 2, and includes a substrate member 25, a locking arm 28 and a second tension spring 29. The board member 25 is formed in a rectangular shape in a front view, and the lower frame member 24 and the first tension spring 27 described above are attached to a substantially central portion thereof by a pivot shaft 26.

A pair of locking arms 28 formed in a substantially J-shape as viewed from the front are provided on both left and right end portions of the substrate member 25.
It is attached so that it can swing. Locking arm 28
Are opposed to each other with a predetermined space therebetween, and are used to lock and hold a handle portion 2a of the LP gas container 2 inserted between the opposed surfaces. The pair of locking arms 28 are formed of a plate-like member, and by twisting a substantially central portion in the longitudinal direction of the plate-like member, opposing surfaces 28a are formed to face each other. The locking surface 28b is formed on the inner peripheral side by bending.

Above the pair of locking arms 28, a second tension spring 29 is attached in parallel with the base member 25 by a pivot shaft 26, and the elastic restoring force of the second tension spring 29 causes
The locking arms 28 are urged in directions to contact each other.
By such biasing, the state in which the pair of locking arms 28 sandwich the LP gas container 2 between the handle portions 2a is maintained, and the locking arms 28 can be prevented from falling off from the handle portion 2a of the LP gas container 2. .

The opposing surface 28a of the locking arm 28 and both side surfaces thereof are formed in a straight or curved shape without a step (see FIG. 3B).
When the locking arm 28 is lifted upward by the elevating device 6 from the state where the handle portion 2a of the LP gas container 2 is sandwiched between a, the handle portion 2a of the LP gas container 2 is attached to the tip of the locking arm 28. It is possible to slide and lock without being caught on the locking surface 28b provided. Further, when the locking arm 28 removed from the handle portion 2a of the LP gas container 2 is moved upward, the locking arm 28 is moved to the side end of the facing surface 28a and the handle portion of the LP gas container 2 2a can be slid without being caught on each other.
