Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rescue device for a chairlift for unloading passengers from a carriage stopped on a railroad track when the chairlift becomes inoperable due to power failure or failure.

A chairlift is a cableway transport facility in which a chair-type carrier is suspended from a rope, and the carrier circulates between stops on the mountain foot side and the mountaintop side mainly on slopes to transport people. In chairlifts, people are transported in a high position away from the ground, so if the equipment stops for a long time due to a power failure or malfunction, the passengers are lowered to the ground from each carrier suspended in the air and rescued. There is a need to. Conventionally, as a rescue device in such a case, a descent tool is attached to a long pole having an inverted U-shaped hook at the tip, and the hook of this pole is hooked to the rope and wrapped around the descent tool. A rescue device that lowers a passenger with a rescue rope is known (see Patent Literature 1, for example).

The rescue device described in Patent Document 1 is configured as follows. This rescue device consists of a rescue hook, a rod connected to this hook, an emergency descent tool hung on the hook, and a descent rope provided for this emergency descent tool. The rescue hook is formed by forming a steel wire into an inverted U shape, one end of which is bent outward, while the other end is extended to form an extension. The rods are connected by fixing metal fittings to the ends. In addition, a latch is fixed to the intermediate portion of the hook extension, from which the emergency descent tool is suspended.

With the above configuration, the operation of lowering the passenger of the carrier is performed as follows. First, from below the carrier, a rescuer operates the base end side of the rod to hook the rescue hook provided on the other end of the rod to the cable on the advancing side of the carrier. At this time, the end of the descent rope provided for the emergency descent equipment is hung near the passenger, and after the passenger attaches the attachment belt provided at the end of this descent rope to the body, the passenger transfers to the descent rope side. . The other end side of the descent rope is supported by a rescuer, and the passengers slowly descend when the descent rope is let out by the rescuer.

Japanese Utility Model Laid-Open No. 3-5449

In the above-described rescue equipment, the emergency descent equipment has a certain weight, and the rod is 10-odd meters long, so the overall weight is considerable, and the burden is imposed on the rescuers. In particular, when the hook is hooked to the cable, the side of the hook where the weight is concentrated is raised to hook the cable, so good operability at this time has been required.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a rescue device for a chairlift that is easy to operate for a rescuer when rescuing a passenger.

The invention of claim 1 comprises a telescopic rescue pole, a hook provided at the tip of the rescue pole and hooked to a rope, a descent device provided with a rescue rope and suspended from the hook, and the rescue pole. a rescue belt attached to a rope;
The hook has a mounting portion attached to the side surface of the tip portion of the rescue pole and protruding sideways. formed so as to extend obliquely upward toward the axial direction side of the rescue pole and be bent into a substantially U shape ,
The substantially U-shaped portion is formed so as to open obliquely downward with respect to the rescue pole when the rescue pole is erected vertically, and the cable is inserted through the opening to move the cable. It is characterized in that it is configured to hang the

According to the present invention, when the rescue pole is erected vertically, the shape of the hook is substantially U-shaped opening obliquely downward with respect to the rescue pole. can be easily hooked to the rope, and the operability of the rescue pole is improved.

Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. 1 is a front view of a rescue device; FIG. The rescue device 10 is roughly composed of a rescue pole 11 , a hook 12 , a lowering device 13 and a rescue belt 16 . The rescue pole 11 is made by combining hollow cylindrical bodies in a nested manner so as to be stretchable in the longitudinal direction, and the tip is connected to the hook 12 .

The hook 12 is made of a steel plate and has a substantially U-shape. The side connected to the rescue pole 11 extends slightly longer, and a hollow cylindrical connecting member 18 is welded to the side of the end. A hole 19 for suspending the lowering device 13 is formed on the side thereof. On the other hand, the opposite end portion is formed in a shape bent outward, and the overall shape of the hook 12 is obliquely downward with respect to the rescue pole 11 when it is connected to the rescue pole 11 and stands vertically. It has a shape that opens to Also, a non-slipper 20 made of rubber material is fitted inside the U-shaped arc portion.

As described above, the hook 12 has the lowering device 13 suspended thereon. The descent device 13 has a rescue rope 14, and is configured so that the moving speed of the rescue rope 14 does not exceed a certain speed. A coupler 15 such as a carabiner is connected to both ends of the rescue rope 14 , and a rescue belt 16 is connected to one of the couplers 15 . The rescue belt 16 is an annular belt body, and has a suspension ring 21 on the upper part, an elastic pad 17 on the lower part, and two belt bodies in the middle part. A fastener 22 is provided for adjusting the size of the annular portion by sliding along the strip.

FIG. 2 is an enlarged view of the connecting portion between the rescue pole 11 and the hook 12. FIG. The rescue pole 11 and hook 12 are connected via a joint 23 . The joint 23 is molded from a plastic resin such as ether-based urethane. It is sandwiched between the end of the rescue pole 11 and the connecting member 18 . As shown in the figure, the rescue pole 11 and the connecting member 18 are fitted on 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 bolts 24. are concatenated as

FIG. 3 is an explanatory diagram of rescue performed using the rescue device 10. As shown in FIG. First, when the chairlift stops, the rescuers 33 and 34 carry the rescue device 10 under the carrier 30 on which the passenger 32 is boarding, and assemble each device in the state shown in FIG. Rescuers 33 and 34 extend the rescue pole 11 to match the height of the cable 31 , and then raise the rescue pole 11 so that the rescue belt 16 is placed in front of the passenger 32 . is hooked on the rope 31.

Next, the passenger 32 seated on the carrier 30 is asked to attach the rescue belt 16 at the tip of the rescue rope 14 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 put on the rescue belt 16, the rescuer 34 pulls the rescue rope 14 to eliminate the slack in the rescue rope 14, and instructs the passenger 32 to slowly move his/her waist away from the seat. . After that, the rescuer 34 slowly lets out the rescue rope 14 to lower the passenger 32 to the ground to rescue him. After completing the rescue, the rescuers 33 and 34 remove the hook 12 from the rope 31, carry the rescue device 10 to the position of the carrier 30 for the next rescue, and rescue the passenger 32 in the same manner.

Generally, in the rescue method as described above, the rescue pole 11 is raised obliquely from the side of the cable 31 and the hook 12 is hooked to the cable 31 to rescue. In such a situation, in the rescue device 10, the hook 12 has a U-shape that opens obliquely downward with respect to the rescue pole 11, so that the hook 12 can be attached to the rope 31 during rescue work from an oblique direction. Hooking becomes easy, and the operability of the rescue pole 11 is improved. 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 deviated when hooking the hook 12 on the rope 31, the joint 23 can absorb the deformation, the hook 12 can be easily hooked to the cord 31 in the same manner as described above, and the operability of the rescue pole 11 is improved.
