JPH1111887A - Hang-up device - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a hang-up device which can lift a heavy object and move easily and safely using a simple configuration where no large-scale heavy machine or the like is required. SOLUTION: A hang-up device is composed of straddle legs 2 capable of moving and being fixed, a jack 3 formed by placing a horizontal member 4 on the legs, a jack operating means, and a chain member 7 which is dangled at the horizontal member with possibility of elongating and equipped at the tip with a locking member for an object to be hung up. The jack 3 is fitted with a handle 10 at one end of a bolt shaft for elevating and sinking the jack, and the height of the jack 3 is made adjustable by means of grasping a grip and turning.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device capable of easily lifting a heavy object, and more specifically, a device capable of easily lifting and moving a heavy object such as a lid for a road gutter or pickled stone. It concerns the device.

[0002]

2. Description of the Related Art Conventionally, when installing or temporarily removing a side gutter lid on a road, an adult man usually has a weight that can be lifted (about 10 kg even for a heavy one), so that it is hardly used for a machine. It was performed manually without resorting to it.

[0003]

However, no matter how much weight can be lifted, the work is usually carried out by bending down on the waist, so that many people suffer from lower back pain. If the weight cannot be lifted by human power, it may be necessary to use a small heavy machine or the like, but it is often difficult to bring the heavy machine to the work place.

Furthermore, when such heavy objects are lifted by human hands, there is even a risk of falling and injuries if the hands slip.

Accordingly, the present invention solves the above-mentioned conventional problems and provides a lifting device capable of easily and safely lifting and moving a heavy object with a simple device without using a large-scale heavy machine or the like. The purpose is to do so.

[0006]

That is, a lifting device according to the present invention comprises a straddle-shaped leg which can be moved and fixed, a jack having a transverse member mounted on the leg, and a jack operating means. And a chain member which is suspended from the horizontal member so as to be freely extendable and has a hooked member locking member at a distal end thereof.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a lifting device according to the present invention will be described with reference to the drawings.

FIGS. 1 and 2 show a lifting device 1 according to the present invention.
1 is a perspective view and a side view showing a first embodiment of the present invention. A pantograph-type jack 3 is provided at the center of the upper end of the straddle-shaped leg 2 having a caster 12 at the lower end. It is desirable that the leg 2 is also opened in the front-rear direction as shown in FIG. A balance-shaped horizontal member 4 is mounted on the upper end of the jack 3. At both ends of the horizontal member 4, a lifting chain 7 formed by a slit 5 having a gap corresponding to the thickness of the chain 7 at the center is provided. A stop member 6 is provided so that the hanging chain can be stretched for 7 hanging lengths.

The jack 3 is provided with a handle 10 at one end of a bolt shaft 9 for raising and lowering the jack. The height of the jack 3 can be adjusted by grasping and rotating the handle 11. From both ends of the horizontal member 4, a lifting chain 7 having a suspended object locking member (hereinafter, referred to as a hanging hook) 8 at the tip thereof is hung.
Reference numeral 13 denotes a lid for the gutter. It is desirable that at least two of the casters 12 have a lock means. This is to prevent the entire apparatus 1 from wobbling during lifting.

The lifting device constructed as described above is used as follows.

First, the handle 10 is rotated in the jack lowering direction to lower the jack 3. The device 1 is installed so that the lock of the casters 12 is released and the object to be lifted (for example, the lid 11 in the side groove) is straddled. Casters 12
The hanging hook 8 is inserted into the gap 14 of the lid in the side groove, and is hooked on the lid 13. The length of the chain 7 is adjusted so as not to be unnecessarily loosened, and the chain 7 is hooked on the chain locking member 6 of the horizontal member 4. By rotating the handle 10 in the jack rising direction, the jack 3 is gradually raised. At this time, lifting hook 8
It is important to lift the cover while taking care not to come off the cover 13. After being lifted to a certain height, the casters 12 are unlocked and moved (FIG. 3).
When the lid 13 once removed is to be returned to the original position, the above operation may be performed in reverse.

When the lid 13 is removed while sequentially moving the lid 13 sideways along the gutter, there is no scaffold on the previously removed side. In such a case, for example, the bridge 17 is passed over the gutter and one side is placed on it. It is good to put on the leg 2 of this.

FIG. 4 shows a second embodiment of the lifting device 1 of the present invention.
FIG. 2 is a front partial cross-sectional view showing the example of FIG. This embodiment is an example used for lifting pickled stones 16. The straddle leg 2 is higher than the previous embodiment so as to straddle the pickle tub 15. Since pickled stones are not always of a fixed shape, they are difficult to grasp and are unstable and dangerous, so it is advisable to put them in the basket 18 and lift them. The basket 18 is preferably made of a stainless steel material, and the handle 19 is desirably reinforced with a thick metal plate.

The legs are integrally formed as shown in FIG. 4 to form a high leg, or as shown in FIG.
It may be through high legs.

Although the lifting device of the present invention is constructed as described above, the jack 3, the lifting hook 8 and the like can be appropriately changed according to the use condition. That is, the jack 3 is not limited to the pantograph type shown in each of the above embodiments, but may be a cylinder type or a hydraulic type as well as a mechanical type. Further, in order to increase the sense of stability at the time of lifting, the horizontal member 4 may not be provided in a single jack 3 in a balance shape, but may be provided so as to extend between two jacks provided in parallel. In that case, it is desirable to link the up and down movement of the two jacks, and it is also possible to pull up with one chain. The hanging hook 8 is lifted according to the shape or structure of the object to be hung such as a so-called hook type as shown in FIG. 1, a holding type as shown in FIG. 4, a carabiner type or a bolt type. It is desirable to have an optimal shape with high security so that it does not easily come off sometimes, and it is desirable that they can be freely replaced. Hook-type hanging hooks are ideal for lifting gratings. It is also important to provide a saw-like tooth shape on each of the suspension hooks so that the suspension can be easily inserted into the suspension hook, or to stick rubber or the like to ensure that measures against slipping are taken.

[0016]

Since the lifting device of the present invention is constructed as described above, a lifting device capable of easily and safely lifting and moving a heavy object with a simple device without using a large-scale heavy machine or the like is provided. can do.
