Particularly, in the present invention, the bending rod 130 and the long-side portion 150 are assembled by the hinge pin 151 so that the second hook 120 and the fixing bracket 152 are integrally rotatable (see arrow B direction) It is possible to prevent the elongate wire part 150 from being assembled directly to the wire, thereby securing the safety of work.

The second hook 120 is rotatable in the axial direction and the second hook 120 is rotated in the direction perpendicular to the axial direction by the fixing bracket 152 and the hinge pin 151 It is possible to freely rotate the connection part between the bent bar 130 and the long side part 150, so that it is easy to handle and manipulate the long side part 150 according to the working position in the field.

The driving unit M may be directly connected to an input shaft for driving the reduction type drum 200 to rotate, and may be driven by a motor provided with a reduction gear, for example. And the motor may be a known pneumatic, hydraulic or electric motor.

Preferably, in the present invention, the deceleration type drum 200 is provided by an inverse cycloid speed reducer.

In this embodiment, the deceleration type drum 200 includes an input shaft 210, a cycloid rotating body 220, a stationary ring 230, and an output ring 240.

Specifically, the deceleration type drum 200 includes an input shaft 210 having an eccentric portion 211 formed therein and rotated by receiving a rotational force; A first planetary roller 2211 and a second planetary roller 2212 which are disposed in parallel with the input shaft 210 at equal radial intervals around the eccentric portion 211 and a plurality of first planetary rollers 2211 and second planetary rollers 2212, A cycloid rotating body 220 composed of a first support plate 2221 and a second support plate 2222 rotatably supporting the planetary rollers 2212 and rotatably supported on the outer periphery of the eccentric portion 211; The number of fixing grooves 231 is greater than the number of the first planetary rollers 2211 and is formed on the inner circumferential surface to sequentially contact the first planetary roller 2211 in accordance with the eccentric rotation of the cyclic rotary body 220, A fixing ring 230 for guiding idle rotation of the main body 220; A plurality of rotation grooves 2410 are formed on the inner circumferential surface and are in contact with the second planetary roller 2212 in order to rotate the output ring 240 ).

First, the input shaft 210 is located at the innermost periphery of the deceleration type drum 200 of the present invention. The input shaft 210 rotates by receiving a rotational force from the outside, and one end of the input shaft 210 is formed into a polygonal shape, And the figure shows that the end portion is formed into a hexagonal shape.

Next, the eccentric portion 211 is formed in the middle of the input shaft 210 so as to have a shaft center spaced from the shaft center of the input shaft 210 by a certain distance.

Accordingly, when the input shaft 210 rotates, the eccentric portion 211 integrally eccentrically rotates.

4 to 6, the cycloid rotating body 200 includes a plurality of first planetary rollers 2211 and a plurality of second planetary rollers 2212, a first support plate 2221 for supporting the first planetary rollers 2211 and the second planetary rollers 2212, And a second support plate 2222.

That is, the first planetary roller 2211 is supported on the first support plate 2221 in parallel with the input shaft 210 at an equal radial spacing around the eccentric portion 211, and the second planetary roller 2212 is also supported by the eccentric portion And is supported on the second support plate 2222 in parallel with the input shaft 210 at radially equally spaced intervals about the input shaft 211.

At this time, the number of the second planetary rollers 2212 is set to exceed the number of the first planetary rollers 2211, and in the figure, nine first planetary rollers 2211 and ten second planetary rollers 2212 are applied .

Each of the first support plate 2221 and the second support plate 2222 forms a single trough, and the first planetary roller 2211 and the second planetary roller 2212 are sandwiched therebetween The first support plate 2221 and the second support plate 2222 are sequentially stacked so that the mutual contact surfaces of the first support plate 2221 and the second support plate 2222 are formed to share the same plane It will be possible.

At this time, the first support plate 2221 and the second support plate 2222 are integrally rotated as one body, and the first and second planetary rollers 2211 and 2212 are rotatably supported by the first support plate 2221 and the second support plate 2222, as shown in FIG.

The inner circumferential surface of the cycloid rotary body 220 having such a structure may be rotatably supported on the outer circumferential surface of the eccentric portion 211, and a sliding bearing 224 may be added to reduce friction therebetween.

Next, the fixing ring 230 is connected to a separate component to be described later and is fixed in a non-rotatable manner. A plurality of fixing grooves 231 made of a cycloid curve are formed on the inner circumferential surface of the fixing ring 230, 231 are designed to be larger than the number of the first planetary rollers 2211 provided on the first support plate 2221 of the cyclic rotary body 220. It is illustrated that ten fixing grooves 231 are formed in the figure.

On the other hand, the step 2301 may be formed on the outer surface of the stationary ring 230 to prevent rotation of the stationary ring 230 by assembling the stationary ring 230 to an external stationary component (not shown).

In addition, it is preferable to add an inner bearing 232 and an outer bearing 233 between the non-rotatable fixed ring 300 and the rotating input shaft 210. Reference numeral 2321 designates an inner bearing 232 as an input shaft 210 to prevent the assembled inner bearings 232 from being separated.

Accordingly, when the eccentric portion 211 rotates together with the input shaft 210, the cycloconic rotating body 220 rotatably supported by the eccentric portion 211 eccentrically rotates to rotate the first planetary roller 2211 Are in contact with the fixing grooves 231 in order and are in contact with each other along the inner circumferential surface of the fixing ring 230.

Such contact relations are shown in Fig. 7 sequentially.

Thus, when the input shaft 100 rotates 10 times in the counterclockwise direction, the cycloid rotary body 220 rotates 10 times in the counterclockwise direction by the eccentric portion 211, while the rotation is performed only once in the clockwise direction.

That is, a reduction ratio of 1/10 between the cycloid rotary body 220 and the fixed ring 230 can be primarily obtained.

Next, the output ring 240 is rotatably positioned by a separate external component. The output ring 240 is rotatable only, its position is not changed, and a plurality of rotation grooves 241 made of a cycloid curve are formed on the inner circumferential surface thereof have.

More specifically, the number of the rotation grooves 241 is designed to be larger than the number of the second planetary rollers 2212 provided in the second support plate 2222 of the cycloid rotating body 220, and 11 rotation grooves 241 .

A ball bearing 242 is added between the output ring 240 to which the decelerated rotational force is output and the input shaft 210 that rotates at the initial rotational speed and the outer circumferential surface of the stationary ring 230 and the outer circumferential surface of the output ring 240 It is preferable to add a separate bearing 243 between the inner circumferential surfaces to reduce the generation of mutual frictional force.

At this time, the second planetary roller 2212, which is rotatably supported on the second support plate 2222, of the cycloconus rotating body 220 that simultaneously performs the revolving and rotating operations contacts the rotation grooves 241 The output ring 240 is rotated. Meanwhile, since the number of the second planetary rollers 2212 is larger than the number of the first planetary rollers 2211, the deceleration is performed again.

This contact relationship is shown in Fig. 8 sequentially.

Accordingly, when the cycloid rotating body 220 rotates 11 times in the clockwise direction, the output ring 240 rotates in the clockwise direction.

That is, the cycloid rotating body 220 and the output ring 240 constitute an inverse cycloid, and a reduction ratio of 1/11 can be obtained secondarily therebetween.

As a result, as illustrated in the drawing, the first deceleration is achieved through the nine first planetary rollers 2211 and the ten fixing grooves 231 contacting with the ten first planetary rollers 2211 and the ten second planetary rollers 2212 and the (1/10) ㅧ (1/11) = 1/110, which is a high speed reduction ratio.

Of course, it is obvious that various reduction ratios can be obtained by appropriately varying the number of the first planetary roller 2211 and the fixing groove 231, the second planetary roller 2212, and the rotation groove 241.

Particularly, in the present invention, it is preferable that the number of the second planetary rollers 2212 is the same as the number of the fixing grooves 231. In this case, the reducer itself can be designed simply and compactly do.

As described above, the deceleration type drum 200 of the present invention is configured such that when the rotational force is inputted to the input shaft 210, the first deceleration is performed between the stationary ring 230 and the cyclic rotary body 220, The decelerated rotational force is finally output through the output ring 240 after the second deceleration is performed between the output ring 240 and the output ring 240. [

The inverse cycloidal deceleration type drum 200 of the present invention may be applied to various mechanical devices requiring deceleration.

Hereinafter, the operation of the deceleration type drum will be described with reference to FIGS. 3 to 8. FIG.

In the decelerating drum 200 of the present invention, rotational force is transmitted to the input shaft 210 according to the operation of the prime mover (not shown).

As a result, the eccentric portion 211 integrally eccentrically rotates as the input shaft 210 rotates, which induces rotation and revolution of the cyclic rotary body 220 on the inner peripheral surface of the fixed ring 230, Deceleration is achieved.

The reduction ratio of the first deceleration is determined by the number of the fixing grooves 231 formed in the stationary ring 230 and the number of the first planetary rollers 2211 supported on the first support plate 2221 of the cycloid rotating body 220 do.

Thereafter, the rotation and revolution of the cycloid rotating body 220 induce the reduced rotation of the output ring 240, whereby the second deceleration is performed here.

The reduction ratio of the second deceleration is also determined by the number of the second planetary rollers 2212 supported on the second support plate 2222 of the cycloid rotating body 220 and the number of the rotation grooves 241 formed in the output ring 240 will be.

As a result, the cyclic deceleration is primarily performed between the stationary ring 230 and the cyclic rotary body 220, and then the reverse cyclic deceleration is secondarily performed between the cyclic rotary body 220 and the output ring 240, The deceleration is performed at a high final reduction ratio through the first reduction ratio and the second reduction ratio.

The decelerated rotational force is output to the outside through the drum housing 260 of the output ring 240. Reference numerals 261 and 262 denote guide blades constituting the drum housing 260, and 2611 denote bolts.

Therefore, the decelerating drum of the present invention is not only capable of decelerating at a higher deceleration ratio due to secondary deceleration, but also has a very simple structure because it does not need to receive the rotational force from the eccentrically rotating cyclic rotary body.

Referring again to FIG. 2, in the present invention, the long side portion 150 can be used both as a motorized type and as a manual type.

The driving unit M may be detachably attached to the input shaft 210 to be driven to rotate the deceleration type drum 200. In this case, And a ratchet wheel 155a for preventing reverse rotation of the input shaft.

9, the input shaft 210 installed in the decelerating drum is formed with a spline S on the outer circumferential surface in the axial direction, and the drive shaft of the drive M is connected to the spline S of the input shaft 210 The driving unit M can be assembled so that the driving unit M can be detachably attached to the input shaft 210 in the axial direction.

A shaft housing 153a may be provided on the body 153 so as to guide a spline axis MS to be assembled with the input shaft 210. A shaft housing 153a may be provided between the shaft housing 153a and the spline axis MS A well-known bearing 154b can be added.

The driving unit M constructed as described above is assembled to the decelerating drum 200 and driven in a motorized manner. If necessary, the decelerating drum 200 is separated from the decelerating drum 200, Lt; / RTI >
