Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hoisting device for hoisting a connecting member such as a wire to a hoisting object such as a hanging load, and more particularly to a hoisting object having various shapes and sizes. The present invention relates to a two-point hanging device capable of adjusting the hanging point interval.

[0002]

2. Description of the Related Art Conventionally, in the work of hoisting an object to be hoisted by a crane or the like, as shown in FIG. It is instructed to support and lift in. It is needless to say that the two points are arranged so that the load center is located in the center of the object to be lifted, but in order to stabilize the object 9 to be lifted, It is necessary to prepare a suspension beam that matches the spacing of the suspension points so that the suspension beam can be lifted up without any extra load. For this reason, even if the intervals of the hanging points are slightly different, they may be fixed and used as they are.

By the way, considering workability and safety,
It is preferable to adjust the hanging point interval according to the object to be hung.

On the other hand, there is known one which can adjust the suspension point interval as shown in FIG.
097). What is disclosed in this publication is a pipe conveying device, which eliminates the displacement of the center of gravity and the pipe P.
It is possible to adjust according to the length of.

It is known that the upper and lower supporting positions (the lower end locking position of the wire 2 and the position of the hook 42) as shown in FIG.
(See 10682 publication). What is disclosed in this publication is a suspension beam for pipes, and a method of expanding and contracting the beam 41 in order to adjust the support position is adopted.

[0006]

However, in the conventional pipe conveying device shown in FIG. 5, the lower end locking position of the hooking wire 2 for a heavy machine is fixed to the suspension beam 43, and therefore, When adjusting the hanging point interval L, only the interval between the hanging wires 3 is changed.
Therefore, as shown in the figure, the vertical component T _{1y of the} tension T ₁ generated on the hooking wire 2 and the tension T ₁ generated on the suspension wire 3
There is a problem in that the suspension beam 43 is bent due to ₂ and. Therefore, it is necessary to increase the strength of the hanging beam 43 to increase the strength of the hanging beam 43, especially for a heavy object to be hoisted. Therefore, it is necessary to increase the capacity of the lifting machine.

On the other hand, in the conventional hanging beam for a pipe shown in FIG. 6, the beam structure is complicated by the method of expanding and contracting the entire beam even if the upper and lower supporting positions can be adjusted at the same time as described above. In addition, when handling heavy objects, there is a possibility that the beam of the expandable structure may be twisted or a large compressive force may be temporarily applied. Moreover, this suspension beam for pipes is of a type in which both ends of a pipe body such as a pipe are lifted while sandwiching both ends of the suspended object by utilizing the compressive force acting on the suspended object itself, and in the first place, two points of the suspended object are locked. Then, the wire is not lifted up as it is, but a force in an oblique direction acts from the wires 2 and 2 on the object to be lifted, and a compressive force is applied to the object to be lifted. Therefore, the suspension beam for pipes shown in FIG. 6 is limited in use to pipes such as pipes, and it is not possible to stably suspend suspended objects of various shapes and sizes upward.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to stably lift objects to be lifted having various shapes and sizes, and An object of the present invention is to provide a suspension device having a function of adjusting the spacing between suspension points, which can be reduced in size and weight.

The two support members 4 and 4 are respectively installed on the left and right sides of the suspension beam 5 so that they are inserted through the notches 11a and 12a and are located between the two grooved steels 8a and 8b. . The support member 4 includes two support plates 14 and 15 arranged in parallel so as to form a vertical plane.

Further, an engagement hole 22 is formed in the substantially central portion of the support plates 14 and 15. As a result, the engagement holes 22 and the plurality of engagement holes 1 formed on the side surface of the beam body 8 are formed.
It is configured such that the support member 4 can be held at a predetermined position in the longitudinal direction of the suspension beam 5 by centering any one of them 3 and inserting and engaging the positioning pin 23. Since a compressive force acts from the support member 4 in the longitudinal direction of the suspension beam 5 via the positioning pin 23, a horizontal force can be reliably received with a simple configuration without exerting a load on other portions. In addition, this positioning pin 23
An engaging groove 23b is formed adjacent to the head 23a of the hanging beam 5 after the positioning pin 23 is set.
The positioning pin 23 is formed by fitting the movable plate 30, which is vertically movable, into the engaging groove 23b.
It is designed to prevent it from coming off. The structure for holding the supporting member 4 at a predetermined position in the longitudinal direction of the suspension beam 5 can be achieved by using not only the positioning pin 23 described above but also a clamp means, a brake mechanism, or the like.

As shown in FIG. 1, the two support members 4,
The hooking wires 2 and 2 of which one end is locked to the lifting machine hook 1 are attached to the hooking wire attachment shafts 6 and 6 of 4, respectively. That is, the upper end ring portion (not shown) of these two hooking wires 2 and 2 (the same structure as the lower end ring portion 3a of the hanging wires 3 and 3 shown in FIG.
(The same applies to other ring portions thereafter) is hooked on the hook 1, and the lower end ring portion (not shown) is provided on the left and right support members 4, 4.

have. The cushioning material 25 ′ is made of a material such as urethane and is provided at both ends of the nut portion 25 so as to be interposed between the nut portion 25 and the support member 4 as shown in the figure.

As described above, the moving means 24 has an extremely simple structure within a limited space, and by manually rotating the handle 27 attached to the outer end of the screw shaft 26, the screw can be fed. The support member 4 can be moved by using the operation. Here, reference numerals “28” and “29” in the drawings denote bearing members that rotatably support the screw shaft 26. The screw shaft 26 of the moving means 24 can be driven by a driving means (not shown) such as a motor. By doing so, it is not necessary to arrange many workers, and the support member 4 can be smoothly moved to a predetermined position in the longitudinal direction of the suspension beam 5. Also, the cushioning material 2

Furthermore, the positioning pin 23 is not transmitted to the screw shaft 26 when the horizontal force of the suspension load is transmitted during the suspension.
Can be told.

The moving means of the present invention is not limited to the one utilizing the screw feeding operation as described above,
For example, a wire or a steel belt may be used.

Next, the operation of this embodiment will be described. When hoisting an object to be hoisted using the hoisting device 10 of the present embodiment, first, the interval of hoisting points is adjusted. That is, the mutual intervals of the lower end ring portions 3a, 3a of the suspension wires 3, 3 attached to the suspension wire attachment shafts 7, 7 of the respective left and right support members 4, 4 correspond to the suspension of an object to be suspended, not shown. The handle 27 is rotated so that the distance between the pieces coincides with each other, and the support member 4 is moved by the moving means 24.
Is moved in the longitudinal direction of the suspension beam 5. Here, since the hook wire attachment shaft 6 and the hanging wire attachment shaft 7 are attached to the respective support members 4 at predetermined positions, they are moved while maintaining their relative positions. Next, the engagement hole 22 of the support member 4 and the engagement hole 1 of the suspension beam 5
After moving the supporting member 4 to a predetermined position so that the center of the positioning member 23 and the center of the supporting member 3 coincide with each other, the positioning pin 23 is fitted and engaged. As a result, the support member 4 is held at a predetermined position in the longitudinal direction of the suspension beam 5. In this way, the interval between the hanging points can be adjusted according to the size of the object to be hung, and the stability of hoisting can be achieved. Therefore, it is not necessary to prepare a suspension beam for each suspension point interval each time, and it can be made extremely versatile.

Next, the upper end ring portions of the hooking wires 2 and 2 attached to the hooking wire attaching shafts 6 and 6 of the left and right supporting members 4 and 4 are hooked and hooked on the hook 1 of the lifting machine. At the same time, the lower end ring portions 3a, 3a of the hanging wires 3, 3 whose spacing between the hanging points is adjusted are locked to the corresponding hanging pieces of the object to be lifted, and the hooking wire 2, which is locked to the hook 1 by the lifting machine. When the upper end of 2 is pulled upward, the object to be lifted, which is locked to the lower end ring portions 3a, 3a of the hanging wires 3, 3, is lifted via the support member 4 held by the hanging beam 5.

In this case, as shown in FIG. 1, when the load W (t) of the object to be hung is set, the tension T ₂ (t) applied to each hanging wire 3 becomes W / 2 (t), and the hanging beam is The tension T ₁ applied to each hooking wire 2 from the balance of the force acting on 5
The vertical component T _1y (t) of (t) is equal to T ₂ (t) and T
The horizontal component force T _1x (t) is hanging beams 5 ₁ (t) acts as compressive force. In this way, the vertical component T _1y (t) of the tension T ₁ (t) applied to each hooking wire 2 and the tension T ₂ (t) applied to each suspension wire 3 are perpendicular to the same point of the suspension beam 5. Since the suspension beams 5 have the same magnitude in opposite directions, no bending is exerted on the suspension beam 5, and only the horizontal component force T _1x (t) of the tension T ₁ (t) applied to each hooking wire 2 is applied. 5 acts as a compressive force. Therefore, the size of the steel material forming the suspension beam 5 can be reduced. For example, when the load W (t) of the object to be hoisted is 40 t, the conventional hanging device uses shaped steel having a height dimension of 500 mm for the hanging beam, but in the present invention, the height dimension of 300 mm is used.
It became possible to use mm shaped steel.

Further, since a compressive force acts from the support member 4 in the longitudinal direction of the suspension beam 5 via the positioning pin 23, the horizontal force can be surely received with a simple structure without exerting a load on other portions. You can Further, in this device, since the cushioning material 25 ′ is provided at both ends of the nut portion 25 so as to be interposed between the nut portion 25 and the support member 4,
The horizontal force can be more reliably received by the positioning pin 23, and the nut portion 25 at the stroke end is moved when the support member 4 moves in the longitudinal direction of the suspension beam.
It is possible to prevent galling between the screw shaft 26 and the screw shaft 26, and prevent galling between the nut portion 25 and the screw shaft 26 when an external force such as a suspension load is applied to the support member 4. Therefore, at the time of lifting, no load is applied to the screw shaft 26 of the moving means 24,
The moving means 24 can be downsized.

As described above, it is possible to reduce the size and weight of the entire lifting device, thereby reducing the equipment cost and downsizing the lifting machine.

It should be noted that the above-described embodiments are described for facilitating the understanding of the present invention and not for limiting the present invention. Each disclosed element is intended to include all design changes and equivalents within the technical scope of the present invention. In the above-mentioned embodiment, the hanging device of the present invention has been described by taking the two-point hanging device with high utilization as an example, but the present invention is applicable to a multi-point hanging device having three or more hanging wires. It is possible to apply.

Therefore, it is not necessary to prepare a suspension beam for each suspension point interval each time, and it can be made extremely versatile.

Further, since the force acting on the suspension beam from the hooking connection member and the suspension connection member via the support member acts on the same point, only bending force acts on the suspension beam in the longitudinal direction without bending.
