The feature is that it has been made possible.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a hoisting machine capable of lifting a heavy object and freely changing the angle of an object.

[0002]

[Prior art]

 Conventionally, a machine for lifting and moving a heavy object has been developed, but even if the lifting work could be performed, the desired surface and angle could not be changed immediately.

[0003]

[Problems to be solved by the device]

 In order to solve the conventional drawbacks, a heavy bearing is supported from both sides by a strong holding part with a built-in free bearing, and it is lifted while being held, and at the same time, the function of the free bearing that operates in the front-rear, left-right direction The purpose of the present invention is to provide a hoisting machine that makes it possible to move the surface and change the angle with a simple operation.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned purpose, a slide column that fits and slides on the column is installed, the screw part is fitted to the lower end of the column, and the free bearing and the cushioning material are fixed to one end, while the tightening hole is provided on the other end. The feature is that it can be operated with a tightening rod.

[0005]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, a sliding sliding pillar 2 is fitted in a fitted state with the supporting pillar 1 made of steel material in contact with the sliding pillar 2 (see the enlarged view of assembly in FIG. 4). Make an annular part that can be screwed in, and screw in the screw part 6. As shown in FIGS. 2 and 3, the tip portion is composed of a free bearing 5, a stopper 9 and a fixed ring 10, and a cushioning material 4 is fixed to the tip portion with a screw. The screw portion 6 is fitted into the central cylindrical space hole wall of the universal bearing 5, and a tightening hole 7 and a tightening rod 8 for operating the screw part 6 are provided at the tip.

[0006]

【Example】

 First, connect a lifting machine such as a crane or chain block to the hanging part 3 in the center of the column 1 shown in FIG. 1, and press the tightening parts from both sides as shown in FIGS. 5, 6 and 7. By inserting and tightening the tightening rod 8 into the hole 7, the flexible bearing 5 shown in FIGS. 2 and 3 is firmly attached to the front cushioning member 4 (annular elastic material such as urethane and rubber). The fitting portions of the support column 1 and the slide column 2 are in a state of being pressed obliquely by the tightening force of the lower portion of the slide column 2, and are firmly and firmly fixed. Now, when actually operating (see FIGS. 5, 6, and 7), it is as follows. Taking Fig. 5 as an example, supposing that the heavy object 11 is rectangular, a rectangular object can be rotated back and forth by the action of the flexible bearing 5, and the number of steps without using a rope is increased as in the conventional case. It's that simple. In the case of FIG. 6, the object is moved to the left and right to bring out the desired surface, and the operation can be easily performed only by changing the fixing position of the tightening device. FIG. 7 shows the case where the heavy object 11 is in the vertical position, and it can be moved as shown in the drawing.

[0007]

[Effect of the invention]

 Since the action of the flexible bearing can be used to the maximum, it is possible to rotate the front, rear, left and right at the same time as lifting, thus improving work efficiency. Simple structure and operation. You can learn the operation method in a short time of practice, and there is no danger. Since each part can be disassembled, cleaning and repair are easy.
