As such, the rope drum 210 of the present invention is provided to be applicable to all ropes having various specifications by adjusting the width of the rope drum 210 according to the thickness and size of the rope 500.

Meanwhile, a mechanical braking device 220 may be provided outside the rope drum 210. A partial area of the rope 500 may be accommodated inside the mechanical braking device 220. The rope 500 may be restrained or separated from the rope 500 according to the operation of the mechanical brake device 220. When the mechanical braking device 220 restrains the rope 500, the power ascender 10 performs a stop operation in which the elevation and descent are stopped. In contrast, when the mechanical braking device 220 is spaced apart from the rope 500, the power ascender 10 may be elevated or lowered. The operation of the mechanical brake device 220 may be controlled by a user.

A rope drum braking device 240 may be provided in another area outside the rope drum 210. The rope drum braking device 240 may be operated by user manipulation. The rope drum braking device 240 may be selectively coupled to the rope drum 210 or separated from the rope drum 210 by a user operation.

When the rope drum braking device 240 is coupled to the rope drum 210, rotation of the rope drum 210 may be prevented. Due to this, the power ascender 10 may be in a stopped state.

When the rope drum braking device 240 is separated from the rope drum 210, the rope drum 210 may be rotated. Due to this, the power ascender 10 may be raised or lowered.

In addition, a separate roller 230 is provided outside the rope drum 210, and the roller 230 may be rotated according to the rise and fall of the power ascender 10. The roller 230 supports the outer surface of the rope 500, so that the movement of the power ascending machine 10 may be made more easily by rotation.

The power ascender 10 may be provided with an accelerator for varying the output value of the motor or engine. For example, a throttle lever 300 may be disposed on the power ascender 10. One end of the throttle lever 300 may be coupled to the first housing 110 or the second housing 130, and the other end of the throttle lever 300 may be coupled to the second housing 130 or the fourth housing 140. The throttle lever 300 may be selectively rotated by user manipulation. When the throttle lever 300 is rotated by user manipulation, the output of the engine or motor may be higher. When the output value of the engine or motor increases, the rotation of the rotation shaft 610 may be rotated more rapidly. Due to this, the power ascender 10 can be moved more rapidly ascending and descending. When the user's external force on the throttle lever 300 is released, the throttle lever 300 may be rotated to a normal position. To this end, an elastic spring may be disposed inside the throttle lever 300.

Meanwhile, a user input unit (not shown) for controlling the power ascender 10 may be provided on an outer surface of the power ascender 10. The user input unit may include a plurality of input buttons to input a user manipulation command. Accordingly, the control unit (not shown) may raise or lower the power ascending machine 10.

Hereinafter, the braking structure of the power ascender 10 will be described.

8 is a cross-sectional view showing the internal structure of the power transmission housing according to an embodiment of the present invention, Figure 9 is a cross-sectional view showing the internal structure of the power transmission housing when the power ascender according to the embodiment of the present invention is raised, and FIG. A cross-sectional view showing the internal structure of a power transmission housing when a power ascender according to an embodiment of the present invention is stopped.

For convenience of explanation, based on FIGS. 8 and 9, it is assumed that when the rotation shaft 610 rotates in a clockwise direction, the power ascender 10 moves upward. In addition, when the rotation shaft 610 rotates in a counterclockwise direction, the power ascender 10 is assumed to descend. In addition, hereinafter, the third housing 130 will be referred to as a power transmission housing 130 and will be described.

8 to 10, a rotation shaft 610 is disposed inside the power transmission housing 130. One end of the rotation shaft 610 is coupled to the engine or motor, and the other end is coupled to the rope drum 210 to transmit power generated from the engine or motor to the rope drum 210. Accordingly, it has been described above that the rope drum 210 can be rotated.

In addition, an inner case 132, a support roller 620, a pressing part 630, an elastic part 640, and a support part 650 may be disposed inside the power transmission housing 130.

The inner case 132 is disposed inside the power transmission housing 130. The inner case 132 is disposed outside the rotation shaft 610. The inner surface of the inner case 132 may be spaced apart from the outer surface of the rotation shaft 610. Accordingly, a gap or a space may be formed between the inner case 132 and the rotation shaft 610.

A space portion 670 in which the support roller 620 or the pressing portion 630 is disposed may be formed on the inner surface of the inner case 132. The space part 670 may be a groove formed by being recessed from the inner surface of the inner case 132 to an outer side of the inner case 132. When a plurality of the support rollers 620, the pressing part 630, the elastic part 640, and the support part 650 are provided on the outer side of the rotation shaft 610, the space part 670 is It may be formed in a plurality on the outside of 610. For example, four space units 670 may be arranged to face each other in pairs based on the rotation shaft 610.

When the inner surface of the inner case 132 on which the space part 670 is formed is the bottom surface of the space part 670, the bottom surface of the space part 670 is the rotation shaft 610 from one end to the other end. The inclined surface 660 may be formed so that the radial distance from the center of the is different. That is, when both ends spaced apart from the bottom surface 660 in the circumferential direction are referred to as one end and the other end of the bottom surface 660, the bottom surface 660 has a radial length from the center of the rotation shaft 610 at one end. The inclined surface 660 may be formed so that this is formed closest and the other end is formed farthest.

Meanwhile, the inner case 132 has been described as an example that is provided as a separate member of the power transmission housing 130, but is not limited thereto, and the inner case 132 is the power transmission housing 130 ) Can be part of. Accordingly, the space portion 670 and the inclined surface 660 may be formed on the inner surface of the power transmission housing 130.

The support roller 620 is disposed outside the rotation shaft 610. The support roller 620 may be rotated together with the rotation of the rotation shaft 610. The support roller 620 may be accommodated in the space part 670. That is, the support roller 620 may slide on the inclined surface 660. As the rotation shaft 610 rotates, the support roller 620 rotates and may move along the inclined surface 660. Since the inclined surface 660 includes regions having different lengths to the outer surface of the rotating shaft 610, the support roller 620 is moved along the inclined surface 660 to the outer surface of the rotating shaft 610. The length can be variable.

In detail, when the support roller 620 is disposed in an area (area (1)) having the shortest radial length from the inclined surface 660 to the rotation shaft 610, the support roller 620 ) Can be in contact with the outer surface. Accordingly, the support roller 620 may press the outer surface of the rotation shaft 610. As a result, rotation of the rotation shaft 610 can be prevented.

In addition, when disposed adjacent to the area other than the area (1) or area (2), the support roller 620 may be spaced apart from the outer surface of the rotation shaft 610. In this case, the rotation shaft 610 may be rotated through a driving force of the motor or engine without interference from the support roller 620.

The pressing part 630, the elastic part 640, and the support part 650 are disposed between the support roller 620 and the inner surface of the power transmission housing 130. In detail, the pressing part 630 presses the support roller 620 by an elastic force generated from the elastic part 640. For example, when the support roller 620 is positioned at the position (2), the elastic portion 640 is compressed, and the pressing portion 630 is compressed by the elastic force of the elastic portion 640 generated at this time. The support roller 620 may be pushed to the (1) position. For example, the elastic part 640 may be a spring.

When the rotation shaft 610 rotates in a clockwise direction (first direction) based on FIG. 9, the support roller 620 is rotated counterclockwise and moves along the inclined surface 660 toward the position (2). Can be. In this case, the support roller 620 may push the pressing part 630 outward. In addition, the elastic part 640 may be compressed.

In addition, when the rotation of the rotation shaft 610 is stopped due to the engine or motor operation being stopped, the pressing unit 630 by the elastic force of the elastic unit 640 causes the support roller 620 to (1) It will be pushed towards the position. Accordingly, when the support roller 620 is disposed at the position (1), the outer surface of the rotation shaft 610 is pressed, so that the rotation shaft 610 can be prevented from rotating.

In summary, when the rotation shaft 610 rotates in a clockwise direction in the direction in which the power ascending machine 10 is elevated, the support roller 620 is rotated counterclockwise so as not to interfere with the rotation of the rotation shaft 610. Can be moved to a location.

However, when the operation of the engine or motor is stopped and the rotation of the rotation shaft 610 is stopped, as shown in FIG. 10, the support roller 620 is applied to the pressing part 630 by the elastic force of the elastic part 640. ) Is moved close to the rotation shaft 610 (position (1)) to prevent the rotation shaft 610 from rotating arbitrarily. That is, when the operation of the engine or motor in the power ascender 10 is stopped, the support roller 620 randomly rotates the rotation shaft 610 (for example, the counterclockwise direction in which the power ascender 10 descends) Direction), it is possible to prevent the power ascender 10 from rising or falling arbitrarily.

11 is a cross-sectional view showing the configuration of a support roller control module according to an embodiment of the present invention, FIG. 12 is a cross-sectional view showing the operation of the support roller control module according to an embodiment of the present invention, and FIG. 13 is an embodiment of the present invention It is a cross-sectional view of a power transmission housing showing a state in which the support roller is released from the rotation shaft according to the operation of the support roller control module according to the following.

11 to 13, the power ascender 10 according to an embodiment of the present invention may include a support roller control module. The support roller control module may separate the support roller 620 from the rotation shaft 610 by user manipulation.

In detail, the support roller control module includes a lever 700, a first gear 710 coupled to one end of the lever 700, a second gear 720 engaged with the first gear 710 and rotated. , A third gear 730 that rotates together with the rotation of the second gear 730 and a moving plate 760 that is rotated by meshing with the rotation of the third gear 730.

The moving plate 760 may be disposed in the power transmission housing 130. The moving plate 760 may be screwed to the inner case 132 through a bolt B. A hole 762 penetrating from one surface to the other may be formed in a region of the moving plate 760 facing the support roller 620. The holes 762 may be provided in plurality to correspond to the number of the support rollers 620.

The support roller 620 may be provided with an extension part 624 that protrudes outward from another area and is inserted into the hole 762. That is, the support roller 620 includes a support roller body 622 selectively in contact with the rotation shaft 610, and an extension part 624 extending outside the support roller body 622 and penetrating the hole 762. ) Can be divided. The cross-sectional area of the extension part 624 may be smaller than the cross-sectional area of the support roller body 622. The cross-sectional area of the extension part 624 may be smaller than the cross-sectional area of the hole 762. The hole 762 may have an area extending a predetermined distance in the circumferential direction so as to be selectively engaged with the extension part 624.

Referring to FIG. 12, when the user rotates the lever 700 in a clockwise direction by manipulating the lever 700, the first gear 710 may be rotated in a clockwise direction. In addition, as the first gear 710 rotates, the second gear 720 engages and rotates, so that the third gear 730 may also rotate. The moving plate 760 may be provided with a fourth gear 740 meshed with and rotated with the third gear 730. The fourth gear 740 may be configured as one body with the moving plate 760 or provided as a separate gear to be coupled to the moving plate 760. Accordingly, the moving plate 760 may be rotated counterclockwise by the rotation of the fourth gear 740.

When the moving plate 760 rotates in a counterclockwise direction, the support roller 620 pushes the pressing part 630 outward, in a direction in which the elastic part 630 is compressed, based on FIG. 13. Can be moved. That is, the support roller 620 may slide the inclined surface 660 so that the constrained state with the rotation shaft 610 is released.

In summary, when the lever 700 rotates in one direction by user manipulation, the moving plate 760 moves the support roller 620 to be separated from the rotation shaft 610. Accordingly, the rotation shaft 610 can be freely rotated without interference from the support roller 620. For example, the rotation shaft 610 may be rotated in a direction in which the power ascender 10 descends.

And, when the lever 700 is rotated in a direction opposite to the one direction by user manipulation, the moving plate 760 may be rotated together. At this time, since the cross-sectional area of the hole 762 is formed to be longer in the circumferential direction than the cross-sectional area of the extension part 624, the support roller 620 may not be rotated even when the moving plate 760 is rotated. In addition, the support roller 620 may be moved to the position (1) so as to restrain the rotation shaft 610 by movement of the pressing part 620 by the elastic force of the elastic part 640.

Accordingly, when the power ascending machine 10 according to the embodiment of the present invention is raised, the support roller 620 may be rotated in a direction not constrained with the rotation shaft 610. And, when the power ascending machine 10 is stopped, the support roller 620 is moved in a direction constrained by the rotational shaft 610 by the elastic force of the elastic part 640, and the power ascending machine 10 You can prevent it from moving. In addition, when the power ascender 10 descends, the user moves the support roller 620 in a direction not constrained by the rotation shaft 610 through the operation of the lever 700, so that the user's predictability according to the descending Can increase.
