Description

  The present invention relates to a chairlift rescue device for lowering a passenger from a carriage stopped on a railroad to the ground when the chairlift becomes inoperable due to a power failure or a failure.

  A chair lift is a cableway transport facility that suspends a chair-type transporter from a rope and transports personnel by circulating and moving the transporter between a stop at a foot of a mountain and a stop at a mountaintop mainly on a slope. In chair lifts, personnel are transported at a high position away from the ground, so if the equipment stops due to a power outage or breakdown, etc., and this will be prolonged, passengers will be lowered to the ground from each stopped carrier in the air and rescued. There is a need to. Conventionally, as a rescue device in such a case, a dropping tool was attached to a long pole having an inverted U-shaped hook at the tip, and the hook of this pole was hooked on a rope and wound around the dropping tool. 2. Description of the Related Art A rescue device that lowers a passenger by using a rescue rope is known (for example, see Patent Document 1).

  The rescue device described in Patent Literature 1 is configured as follows. The rescue device includes a rescue hook, a rod connected to the hook, an emergency descent tool suspended from the hook, and a descent rope provided for the emergency descent tool. The rescue hook is a steel wire formed in an inverted U-shape, one end of which is bent outward, while the other end is extended to form an extension. A hook is fixed to the end to connect the rods. A hook is fixed to an intermediate portion of the hook extension, and an emergency descent tool is suspended there.

  With the above configuration, the operation of lowering the passenger of the transporter is performed as follows. First, the rescuer operates the basal end of the rod from the lower part of the transporter to hook the rescue hook provided on the other end of the rod on the traveling rope of the transporter. At this time, the end of the descent rope provided for the emergency descent equipment is suspended near the passenger, and after the passenger wears the wearing belt provided at the end of the descent rope to the body, the passenger moves to the descent rope side . The other end of the descending rope is supported by a rescue worker, and the rescue worker pulls out the descending rope, so that the passenger descends slowly.

Japanese Utility Model Publication No. 3-54949

  In the rescue apparatus as described above, the emergency descent tool has a certain weight, and the rod body also has a considerable weight because it has a length of more than 10 meters, which imposes a considerable burden on the rescuer. In particular, when the hook is hooked on the cable, the hook, on which the weight is concentrated, is raised and hooked on the cable, so that good operability at this time is required.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a rescue device for a chairlift that is easy for a rescuer to rescue a passenger.

  The invention of claim 1 includes a telescopic rescue pole, a hook connected to the rescue pole and hooked on a cable, a descent device having a rescue rope and suspended from the hook, and a rescue rope. And a rescue belt attached thereto, wherein the rescue pole and the hook are connected via a joint formed of a plastic resin.

  According to a second aspect of the present invention, in the rescue apparatus for a chair lift according to the first aspect, the joint has a cylindrical shape, and the rescue pole and the hook are externally fitted and connected from both ends of the joint. It is characterized by doing.

  According to the present invention, since the hook and the rescue pole are connected via the joint formed of the plastic resin, the joint may be slightly displaced when the hook is hooked on the cable. Since it can be deformed and absorbed, the hook can be easily hooked on the rope, and the operability of the rescue pole is improved.

Front view of rescue equipment Enlarged view of connection Illustration of rescue

  Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front view of the rescue device. The rescue device 10 roughly includes a rescue pole 11, a hook 12, a descent device 13, and a rescue belt 16. The rescue pole 11 is formed by nesting hollow cylinders in a nested manner and is stretchable in the longitudinal direction.

  The hook 12 is formed in a substantially U-shape by a steel plate. The side connected to the rescue pole 11 has a slightly extended shape, and a hollow cylindrical connecting member 18 is welded to the side of the end. A hole 19 for hanging the descending device 13 is formed on the side of the hole. On the other hand, the opposite end is formed in a shape bent outward, and the shape of the hook 12 as a whole is obliquely downward with respect to the rescue pole 11 when the hook 12 is connected to the rescue pole 11 and stands upright. It has a shape that opens to. Further, a slip stopper 20 made of a rubber material is fitted inside the U-shaped arc portion.

  As described above, the lowering device 13 is suspended from the hook 12. The descending device 13 includes a rescue rope 14, and is configured so that the moving speed of the rescue rope 14 does not exceed a certain speed. A connector 15 such as a carabiner is connected to both ends of the rescue rope 14, and a rescue belt 16 is connected to one connector 15. The rescue belt 16 is an annular band, which is provided with a suspension ring 21 at an upper portion, a resilient pad 17 at a lower portion, and two belts are hooked at an intermediate portion. A fastener 22 is provided for adjusting the size of the annular portion by sliding along the band.

  FIG. 2 is an enlarged view of a connecting portion between the rescue pole 11 and the hook 12. The rescue pole 11 and the hook 12 are connected via a joint 23. The joint 23 is formed of a plastic resin such as ether-based urethane, and both ends are formed in a columnar shape corresponding to the inner diameters of the rescue pole 11 and the connecting member 18, respectively. The rescue pole 11 is sandwiched between the end of the rescue pole 11 and the connecting member 18. As shown in the figure, a rescue pole 11 and a connecting member 18 are externally fitted to both ends of the joint 23, and the rescue pole 11 and the connecting member 18 have plasticity by fixing the joint 23 to each with a bolt 24. Are connected.

  FIG. 3 is an explanatory diagram of rescue performed using the rescue device 10. First, when the chair lift stops, the rescuers 33 and 34 carry the rescue device 10 below the transporter 30 on which the passenger 32 is boarding, and assemble each device in the state of FIG. Subsequently, the rescuers 33 and 34 extend the rescue pole 11 so as to conform to the height of the rope 31, and then raise the rescue pole 11 to set the hook 12 at a position where the rescue belt 16 is in front of the passenger 32. Is hooked on the cable 31.

  Next, the passenger 32 seated on the transporter 30 has the rescue belt 16 at the tip of the rescue rope 14 attached to the chest, and the fastener 22 is adjusted so that the rescue belt 16 is in close contact with the chest. After confirming that the passenger 32 has worn the rescue belt 16, the rescuer 34 pulls the rescue rope 14 to eliminate the slack of the rescue rope 14, and instructs the passenger 32 to slowly shift his / her waist away from the seat. . Thereafter, the rescuer 34 gently advances the rescue rope 14 to lower the passenger 32 to the ground and rescue the passenger. After the rescue is completed, the rescuers 33 and 34 remove the hook 12 from the cable 31 and transport the rescue device 10 to the position of the carrier 30 for performing the next rescue, and similarly rescue the passenger 32.

  In general, in the above-described rescue method, it is usual that the rescue pole 11 is raised obliquely from the side of the cable 31 and the hook 12 is hooked on the cable 31 to perform rescue. In such a situation, the rescue device 10 has a hook-shaped U-shape that opens obliquely downward with respect to the rescue pole 11. It becomes easy to stop, and the operability of the rescue pole 11 improves. Further, since the hook 12 and the rescue pole 11 are connected via the joint 23 made of a plastic material, even if the position of the hook 12 is slightly shifted when the hook 12 is Can be deformed to absorb this, so that the hook 12 can be easily hooked on the rope 31 as described above, and the operability of the rescue pole 11 is improved.
