Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a lifeline retractor, and more particularly, to a lifeline retractor for quickly winding a lifeline in a form that facilitates firing of the lifeline with a firing gun.

[0002]

[Prior art]

 Conventionally, in order to rescue a rescuer who was left behind in the middle of the river during a disaster such as a flood, a lifeboat was fired with a firing gun from the riverbank to the opposite shore, and the main line was passed. To reach the location of the rescuer. Here, a lifeline is a rope whose mass is smaller than that of the main rope in order to reduce the energy required for launch.

[0003] At this time, the launching of the lifeline is not always successful at one time. If the launching of the lifeline fails, the lifeline must be pulled back and fired again. In the past, at this time, the rescue rope was groped back, simply wrapped in a box, and then fired again. In such a case, it is necessary to quickly pull back and fire the rescue line manually to rescue the rescuer in need.

[0004]

[Problems to be solved by the invention]

 However, such a conventional method requires a considerable amount of time to pull back the lifeline. In addition, when the lifeline was relaunched, the lifeline was often entangled inside the box, and there was a high risk that the lifeline would fail to fire again during the relaunch. Under such circumstances, if it takes time to deliver the rescue line, the worst situation may occur, such as the rescuer being washed away by the river during that time.

[0005] In order to shorten the time required for pulling the lifeline, it is conceivable to connect the handle to the spool and rotate the handle to sequentially wind the lifeline on the spool in an aligned state. However, in this method, simply winding on a spool cannot completely prevent entanglement of the lifeline, and cannot properly avoid the risk of failure of relaunch of the lifeline. Furthermore, in the case of relaunch, not only the force to pull out the lifeline but also the force to rotate the spool itself is needed, so if the power of the firing gun is insufficient, the tip of the fired lifeline will not reach the opposite shore. However, there was a high risk of failure to relaunch the lifeline.

Therefore, the present invention requires that the time required for winding the lifeline be reduced, the entanglement of the wound lifeline be avoided, and the power of the firing gun at the time of relaunch be great. It is an object of the present invention to provide a lifeline retractor capable of launching a lifeline without using the same.

The frame 2 is provided with a guide member 8. First, a frame extension 80 is fixed to a rear side surface of the frame 2 by a pin 81 (FIG. 3), and an upper surface of the frame extension 80 is flush with the top plate 20. The lower end of a guide column 82 extending perpendicular to the frame extension 80 is fixed to the rear end of the upper surface of the frame extension 80. A cable insertion member 84 is detachably fixed near the upper end of the guide column 82. The cable insertion member 84 has a thickness in the front-rear line direction in FIG. 1 and has a through hole 84a formed along the height direction, through which the guide column 82 penetrates. Further, the cable insertion member 84 is formed with a groove surface 84b extending from the through hole 84a toward one end surface of the cable insertion member 84 and extending perpendicularly to the thickness direction of the cable insertion member 84 (FIG. 2). A pin 83 is provided so as to cross the groove surface 84b in the thickness direction of the cable insertion member 84, and the cable insertion member 84 is fixed to the guide column 82 by tightening the pin 83.

The cable insertion member 84 has a plate-like introduction-side guide 85 and a winding-side guide 86 which are located on the other end face side from the through hole 84a and are arranged in the front-rear direction of FIG. 2). The introduction-side guide 85 and the winding-side guide 86 are provided in parallel with the thickness direction of the rope insertion member 84. The introduction-side guide 85 and the winding-side guide 86 are formed with cable insertion holes that respectively penetrate the introduction-side guide 85 and the winding-side guide 86 along a front-rear line. The cable insertion holes are respectively provided with vertical grooves 85a, 86a extending upward from the lower ends of the introduction-side guide 85 and the winding-side guide 86 to near the center, and lateral grooves 85b, 86b extending laterally from the upper ends of the vertical grooves. , And substantially circular holes 85c and 86c formed at the end opposite to the side of the horizontal groove connected to the vertical groove. The vertical grooves 85a and 86a and the horizontal grooves 85b and 86b have a shape overlapping each other in the thickness direction of the cable insertion member 84, but the circular holes 85c and 86c have different diameters. Specifically, the diameter of the circular hole 85c formed in the introduction-side guide 85 is set to be slightly larger than the diameter of the lifeline wound around the core member 7. On the other hand, the diameter of the circular hole 86 c formed in the winding guide 86 is set to be slightly smaller than the diameter of the life-saving rope wound on the core 7. A plurality of cable insertion members 84 are prepared, and can be replaced with the most suitable one according to the diameter of the lifeline to be wound.

Next, based on the above configuration, the operation of the life search retractor according to the embodiment of the present invention will be described. First, one end of the lifeline is passed through the large-diameter hole 70a of the capturing means 70 of the core material 7 shown in FIG. 4 from the outer peripheral side of the core material 7 and is moved to the small-diameter hole 70b. Hold one end of the lifeline. Thereafter, the protrusion 63A of the core receiving portion 63 is inserted into the vertical groove 71a of the mounting portion 71 of the core 7, and the core 7 is rotated so that the projection of the core receiving portion 63 is inserted into the lateral groove 71b of the mounting portion 71. It guides the part 63A. Thereby, the core 7 is fixed to the inclined plate 6 through the core receiving portion 63 and the core support plate 60.

Next, a lifesaving cable is passed through the cable insertion member 84. Specifically, the lifesaving rope is engaged with both the circular hole 85c of the introduction-side guide 85 and the circular hole 86c of the winding-side guide 86 through the vertical grooves 85a and 86a and the horizontal grooves 85b and 86b. Here, since the circular hole 85c has a larger diameter than the lifeline and the circular hole 86c has a smaller diameter than the lifeline, the lifeline is held with sufficient clearance in the circular hole 85c of the introduction-side guide 85. The guide 86 is pressed and held in the circular hole 86 c of the winding guide 86.

Then, an electric driver 57 (FIG. 2) having a socket wrench 57 A is connected to the driving force input portion 50 A of the handle shaft 50 via a flexible wire 57 B, and the handle shaft 50 (FIG. ) To rotate. The electric driver 57 may be directly connected to the driving force input unit 50A without using the flexible wire 57B. However, when the electric driver 57 is connected via the flexible wire 57B, the output shaft of the electric driver 57 is coaxial with the driving force input unit 50A. Since the handle shaft 50 can be continuously rotated without being held in the emergency, there are many advantages in an emergency such as a rescue operation. When the battery of the electric driver 57 has run out, the handle shaft 50 can be rotated by connecting the handle 58 as shown in FIG.

When the handle shaft 50 is rotated in this manner, the gear member 51 rotates about the axis of the handle shaft 50 integrally with the handle shaft 50. The large-diameter gear member 53 meshing with the gear member 51, the communication shaft 54 fixed to the large-diameter gear member 53, the rotary plate support 55 fixed to the communication shaft 54, and the rotary plate support 55 are fixed. The rotating plate 4 integrally rotates about the axis 3X of the small diameter portion 3B of the support shaft 3. Accordingly, the bracket 40 fixed to the rotating plate 4 and the inclined plate 6 supported by the inclined shaft 43 of the bracket 40 pivotally move about the axis 3X of the small diameter portion 3B of the support shaft 3. At this time, while maintaining the state where the axis 6X of the inclined plate 6 is inclined at 40 ° with respect to the rotary plate 4, the axis 6X pivots around the axis 3X of the small diameter portion 3A of the support shaft 3 to form two cones. Draw a trajectory as if the vertices were aligned and aligned on the same axis. That is, the intersection of the axis 3X of the small diameter portion 3B of the support shaft 3 and the axis 6X of the inclined plate 6 does not move.

At this time, the gear portion 6 A formed on the edge of the inclined plate 6 meshes with the pinion gear 30 fixed to the projecting portion 3 A of the support shaft 3, so that the inclined plate 6 As it moves, it rotates with respect to the bracket 40 about the axis 6X of the inclined shaft 43 while meshing with the pinion gear 30. As a result, the core 7 rotates around the axis 6X via the inclined plate 6, the spacer 61, the core support 60, and the core receiving portion 63. Further, as described above, the axis 6X pivots about the axis 3X of the small-diameter portion 3A of the support shaft 3, and accordingly, the core member 7 moves on the top plate 20 and the rotating plate 4 While maintaining an angle of 40 ° with respect to, both the rotational motion about the axis 6X and the turning motion about the axis 3X are performed.

By the movement of the core member 7, the life-saving cable is wound around the core member 7. At this time, one end of the life-saving cable is captured by the capturing means 70, and a part of the life-saving cable is compressed and captured by the circular hole 86c of the winding-side guide 86 of the cable insertion member 84. Between the insertion member 84 and the core 7, tension is always applied to the life-saving cable. Thus, the lifeline does not become entangled during winding, and the lifeline is wound on the core member 7 under tension and does not become loose. Further, since the rescue line is supported with sufficient clearance in the circular hole 85c of the introduction-side guide 85, the rescue line can be smoothly guided to the circular hole 86c of the winding-up guide 86.

At this point, when the core member 7 completes one turning movement about the axis 3X, the rotation amount of the core member 7 about the axis 6X is shifted by about one lifeline. The gear ratio between the pinion gear 30 and the gear portion 6A of the inclined plate 6 is appropriately set so that the amount becomes as follows. As a result, the rescue line is wound up uniformly and without gaps in a twill-like state as shown in FIG.

After winding of the lifeline is completed, the core 7 is removed from the core receiving portion 63, and the core 7 is further removed from the lifeline. At this time, since the innermost tip of the wound lifeline is captured by the capturing means 70 of the core member 7, when the lifeline itself is removed from the core member 7, only the distal end portion becomes the core. It does not come off from the material 7 and is pulled out from the wound lifeline. FIG. 6 shows a state in which the wound material of the lifeline from which the core material 7 has been removed is stored in a box body such as cardboard. At the time of relaunch of the lifeline, the distal end of the lifeline captured by the capturing means 70 is attached to a firing gun and relaunched.

FIG. 7 shows a modification of the guide member. For this, a guide member 108 shown in FIG. 7 is used instead of the guide member 8 of the above-described embodiment. The guide member 108 in FIG. 7 is provided on the frame extension 80 in the same manner as the guide member 8 in the above embodiment. The lower end of a vertically extending guide column 182 is fixed to the rear end of the upper surface of the frame extension 80. The guide support 182 has a large-diameter portion 182A extending from the frame extension portion 80 and a small-diameter portion 128B extending upward from the upper end of the large-diameter portion, and a connecting portion between the large-diameter portion 128A and the small-diameter portion 128B is provided. , A step portion 182a is formed. The cable insertion member 184 is externally supported by the small diameter portion 128B and sits on the step portion 182a.

The cable insertion member 184 has a thickness in the front-rear line direction in FIG. Further, in the rope insertion member 184, a through hole 184a having a diameter slightly larger than the small diameter portion 182B of the guide support 182 is formed along the height direction so as to penetrate the small diameter portion 182B of the guide support 182. After the penetration, the cable insertion member 184 is rotatably supported by the guide column 182, and the step 182 a forms a sliding surface of the cable insertion member 184.

The cable insertion member 184 is integrally provided with a plate-like introduction guide 185 and a take-up guide 186 that extend in parallel with the through hole 184a. The introduction-side guide 185 and the winding-side guide 186 are provided in parallel to each other along the front-rear line direction in FIG. The introduction-side guide 185 and the winding-side guide 186 are formed with cable insertion holes that respectively penetrate the introduction-side guide 185 and the winding-side guide 186 along a front-rear line. The cable insertion holes include vertical grooves 185a, 186a extending upward from the lower ends of the introduction-side guide 185 and the winding-side guide 186 to near the center, and horizontal grooves 185b, 186b extending laterally from the upper ends of the vertical grooves. It is formed. In the above-described embodiment, the cable insertion holes 85a, 86a and 85b, 86b have a shape overlapping each other in the thickness direction of the guides 85, 86 (FIG. 3). The distances from the through hole 184a of the vertical groove 185a and the vertical groove 186a are different from each other and do not overlap. The horizontal groove 185b extends from the vertical groove 185a toward the through hole 184a, while the horizontal groove 186b extends from the vertical groove 186a in a direction away from the through hole 184a. The width of each of the vertical grooves 185a and 186a is set to be slightly larger than the diameter of the lifesaving rope wound around the core member 7. On the other hand, the width of the lateral groove 185a formed in the introduction-side guide 185 is slightly larger than the diameter of the life-saving cable, and the width of the lateral groove 186a formed in the winding-side guide 186 is formed slightly smaller than the diameter of the life-saving cable. ing.

When the life-saving cable is passed through the cable insertion member 184, the life-saving cable is engaged with both the horizontal grooves 185b and 186b through the vertical grooves 185a and 186a. Here, the lateral grooves 185b and 186b have a function of holding a lifeline, similarly to the circular holes 85c and 86c of the above-described embodiment. That is, the rescue line is held with a sufficient space in the lateral groove 185 b of the introduction-side guide 185, and is pressed and held in the lateral groove 186 b of the winding-side guide 186.

According to the cable insertion member 184, since the positions of the vertical groove 185a and the vertical groove 186a do not overlap with each other, it is possible to favorably prevent the cable passing therethrough from dropping off. Further, in the above-described embodiment, the life-saving cable is not supported at one point as in the circular holes 85c and 86c of the above-described embodiment, and the life-saving cable is wound along the lateral grooves 185b and 186b during winding. Because the lifeline can be shifted, the lifeline can be wound up satisfactorily regardless of the state of the lifeline, such as twisting. Further, since the cable insertion member 184 is rotatably provided around the guide column 182, the cable insertion member 184 can cope with the frictional force of the life-saving cable, and can avoid inconvenience due to excessively strong tension acting on the life-saving cable. Can be.

The lifeline retractor according to the present invention is not limited to the above-described embodiment, and various modifications and improvements can be made within the scope described in the claims for utility model registration. For example, in the present embodiment, the core material support plate 60 is provided on the inclined plate 6 with the spacer 61 interposed therebetween, and the core material 7 is installed thereon. The core member 7 may be directly installed detachably.

Further, in the present embodiment, the cable insertion holes are constituted by the vertical grooves 85a, 86a, the horizontal grooves 85b, 86b, and the circular holes 85c, 86c. However, only the vertical grooves from the edge of the cable insertion member 84 or only the horizontal grooves are provided. It is also possible to provide a shape in which only the guide hole is provided and guided to the circular hole.

[Effect of the invention]

 According to the lifeline retractor of the first aspect, when a driving force is input to the driving force input portion, which is one end of the rotation transmission mechanism, the lifeline is wound around the core material, and the rescue of the lifeline is quickly performed. Can be done suddenly. In addition, since the wound lifeline has a twill shape, the lifeline does not easily become tangled when the lifeline is relaunched, increasing the success rate of relaunch. In addition, a guide member is provided to pass the lifeline by pressing it, so when winding the lifeline around the core material, the lifeline will not be loosened, and the wound lifeline will collapse and become entangled or entangled. There is no fear. Furthermore, since the core material has a hollow cylindrical shape, the wound lifeline can be removed from the core material, and it is possible to remove the lifeline from the core material before relaunching the lifeline. it can. As a result, at the time of relaunch, even if the output of the firing gun is small to a certain extent, it is possible to successfully launch the lifeline. In addition, since it has a simple configuration, it can be miniaturized and can be carried around at any rescue site as a portable device.

According to the second aspect of the present invention, a power tool or a manual handle can be selectively connected to the one end exposed to the outside of the rotation transmitting mechanism. Power tool and manual handle can be used properly. As a result, hoisting can be carried out with a manual handle in an emergency such as when the battery has risen, while using a power tool that can be quickly carried out without requiring labor for winding.

According to the third aspect of the present invention, since the angle between the inclined plate and the rotary plate is 50 °, the rescue rope can be efficiently wound. In addition, the rescue line after winding is in an easy-to-handle form, which reduces the risk of relaunch failure.

According to the life-saving rope winding machine of the fourth aspect, since the cable-inserting member is replaceable, it is possible to selectively change the inner diameter and the shape of the cable-inserting portion depending on the diameter of the life-saving cable. It can be used to wind up various life-saving cables.
