Description

[Detailed Description of the Invention] This invention relates to a cylinder hanger for moving propane gas cylinders loaded onto a truck, for example, when the cylinders are unloaded onto the road.

The purpose of this invention is to provide a cylinder hanger that is inexpensive, robust, and easy to handle.

The structure of this invention in accordance with the above purpose is that an annular support member that fits into the cylinder body and a lower locking hook that engages with the bottom skirt of the cylinder are provided at the middle and lower end of the rod-shaped body, respectively, to hold the cylinder. The cylinder is supported at two points, and a hanging wire is locked at a selected position on the curved part provided at the upper end of the rod-shaped body, so that the cylinder supported at two points can be held in any tilted position. , when raising and lowering the cylinder and locking it, the operator grasps a part of the rod-shaped body, first tilts the cylinder, fits the annular support member into the cylinder body from above, and then lifts the rod-shaped body. By pulling the body downward, engaging the lower locking hook with the bottom skirt, and then standing the cylinder upright, the engaging operation is performed easily and reliably,
Furthermore, in the detachment operation, the operator similarly grasps the two parts of the rod-shaped body, first tilts the cylinder, and then pulls the rod-shaped body downward to detach the lower locking hook from the bottom skirt. Next, the rod-shaped body is pushed upward to detach the annular support member from the cylinder body, thereby making it possible to perform the detachment operation easily and reliably.

The structure and operation of this invention will be explained below based on FIGS. 1 and 2.

FIG. 1 is a perspective view showing the structure of a cylinder hanger which is an embodiment of this invention, in which 1 is a rod-shaped body made of a metal such as iron or stainless steel, or a rigid body such as carbon fiber, and 2 is the upper end of the rod-shaped body 1. 3 is an annular support member fixed to the middle part of the rod-shaped body 1; 4 is a hole provided in the curved portion 2; 5 is a bolt passing through the hole 4; 6 is a shank; , screwed together with bolt 5.

T is a hanging wire whose one end is fastened to the shank 6.

8 is a handle attached to the bottom of the rod-shaped body 1; 9 is the rod-shaped body 1;
It is a lower locking hook provided at the lower end of the .

Hereinafter, based on FIG. 2, an explanation will be given of the operation when raising and lowering a propane gas cylinder using a cylinder hanger as shown in FIG. 1.

In FIG. 2, 11 is the head cover of the cylinder, 12 is the cylinder body, 13 is the bottom skirt of the cylinder, and 14 is the ground.

Now, when the cylinder body 12 is tilted as shown in FIG. 1A, one end 13a of the bottom skirt 13 separates from the ground 14, creating a gap between it and the ground 14.

On the other hand, after fitting the annular support member 3 to the cylinder main body 12 from above, the cylinder hanger operator engages the lower locking hook 9 with the one end 13a of the bottom skirt 13. , the rod-shaped body 1 is pulled down to move the locking hook 9 into the gap formed between the one end 13a of the bottom skirt 13 and the ground 14.

At this time, since the structure is such that there is a clearance a between one end 13a of the bottom skirt 13 and the tip of the locking hook 9, the locking hook 9 can be easily moved.

Next, when the cylinder body 12 is made to stand approximately upright with respect to the ground 14, it will be in the state shown in FIG. 2B.

That is, due to the gravity of the cylinder body 12, the lower locking hook 9 engages with one end 13a of the bottom skirt 13, and the entire cylinder hanging tool moves upward by a distance corresponding to the play space indicated by a in FIG. do.

As a result, the annular support member 3 slides upward by a distance a relative to its original position in FIG.

However, since there is still a distance left to the shoulder 12' of the cylinder, the annular support member 3 is stably fitted to the cylinder main body 12.

Subsequently, as shown in FIG. 2CK, when the hanging wire γ is lifted up by a crane or the like (not shown), the cylinder body 12 is engaged with the annular support member 3 fitted thereto and one end 13a of the bottom skirt 13. The rod-shaped body 1 leaves the ground 14 and rises together with the rod-shaped body 1 while maintaining a stable posture while being supported by the lower locking hooks 9 that have been fitted together.

When the cylinder body 12 reaches, for example, the loading platform of a truck for transporting cylinders, the cylinder body 12 is placed in an inclined position as shown in FIG. , lower locking hook 9 and bottom skirt 1
Since a play space a is created between the handle 8 and one end 13a of the rod-shaped body 1, the operator of the hanging tool grasps the handle 8 and pulls the rod-shaped body 1 toward himself.

By pushing up the entire hanging tool, the fitting of the annular support member 3 to the cylinder body 12 can be easily released.

The hanger is thus separated from the cylinder.

As described above, in this invention, the annular support member 3 fixed to one end of the rod-shaped body 1 is fitted to the cylinder body 12, and the lower locking hook 9 provided at the lower end of the rod-shaped body 1 is fitted into the cylinder body 12. engaged against the bottom skirt 13 of the cylinder;
By locking a hanging wire γ at a selected position on a curved part 2 provided at the upper end of a rod-like body 1, a cylinder hanging tool is provided which raises and lowers a cylinder main body 12 while stably holding it.

Therefore, the cylinder hanger according to this invention is designed to effectively utilize the shape of the cylinder to support it, and therefore has a simple structure and is robust.

In addition, since the required members are extremely small, it is small, lightweight, and inexpensive.

Being small and lightweight is a practical advantage, especially in the case of a cylinder hoist that is used by being attached to a crane mounted on a truck for transporting cylinders.

Furthermore, since the annular support member 3 and the lower locking hook 9 are connected by the rod-shaped body 1 made of a rigid body such as metal, the operator can hold the annular support member 3 by hand when engaging and disengaging the cylinder. This provides an excellent effect in that it is possible to easily and reliably engage and disengage the cylinder by gripping only the rod-shaped body 1 without having to touch the cylinder.

In particular, since it is possible to engage and disengage the cylinder by gripping the lower part of the rod-shaped body 1 from below, when raising and lowering a cylinder placed on a high place such as the loading platform of a truck,
Extremely convenient for handling and operation.

In addition, a curved portion 2 is provided at the upper end of the rod-shaped body 1, and
Since the locking position of the hanging wire 1 on the curved portion 2 can be variably set, the moment acting on the cylinder around the locking position can be greatly reduced according to the relationship between the locking position and the center of gravity of the cylinder. By changing the angle, it is possible to adjust the tilted posture of the cylinder while it is being raised and lowered.
