JP3065040U - Lifting rescue release equipment lifting automatic telescopic pole C-type hook - Google Patents

Abstract

(57) [Summary] [Purpose] Because the rescue release gear mounting ring under the hook at the pole tip of the lift rescue device is fixed to the pole post, when the rescue is started, the weight of the passenger is The resilience pole will be independent and will always be vertical when the load is applied to the C-shaped hook ring without tilting the pole tip post even if the rescue pole is tilted. did. The lower part of the C-type hook is softly connected to the mounting ring of the lower part by means of a spring parallel to the post, so as to obtain a damping effect when the lowering part is not mounted on the C-type hook. [Construction] The C-type hook is made of a solid material, and the cassette plate is welded to the part to be hung on the supporting rope and the ring for attaching the lifting / lowering device, and the cassette plate to the middle and slightly upper part. This is a configuration that is soft-coupled with a spring.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 Lift rescue equipment becomes inoperable due to a failure such as a power outage at a facility during operation, and when it is no longer possible to resume operation, rescue equipment is used and passengers can be safely transported from the carrier to the ground or on the snow in a short time It is a tool to drop quickly.

[0002]

[Prior art]

 The conventional rescue pole hook has a structure in which a hanging ring for hanging a lifting device is provided directly below the hook at the tip of the post of a bamboo pole and an automatic telescopic pole. Therefore, when performing rescue, suspend the lifting equipment on the ring, hook the ropes, hook the ropes, and lower the passengers from the transporter. As a result, bending stress was applied to the suspension ring between the pole and the hook, causing the inconvenience of bending the hook.

[0003]

[Problems to be solved by the invention]

 There is a need for a mechanism that can prevent the hook from being bent and easily change the angle at which the pole stands when the passenger descends, as described in the related art 0002.

[0004]

[Means for Solving the Problems]

 The problem 0003 to be solved by the present invention is that the C-type hook of the present invention has a structure in which the hook and the ring are made independent, the cassette plate is welded to the upper back portion, and the ball post is connected to the tip of the pole post via this. . Also, since the C-type hook was hanging out, the lower end of the ring and the post were tied with a soft spring and softly fixed against run-out such as carrying the pole. By installing this device at the tip of the pole post, the C-type hook is always kept vertical when the lifting device is hung on the ring, and when the weight of the passenger who supports and hooks the hook and rescues acts on the ring, The pole can be changed around the ball joint to a position where it does not hinder the passenger passage while the mold hook remains vertical.

[0005]

[Action]

 A 1-meter post is fixed to the end of the telescopic pole with a screw, and a C-type hook is attached to the end of the post via a ball joint. The lower ring of the hook and the post are joined by a soft spring. The structure was not used. When rescuing a passenger from a carrier, first go under the carrier with a rescue pole and a lifting device, and the rescuer attaches the lifting device to the ring under the hook of the C-shaped pole at the tip of the rescue pole on snow or on the ground. Attach. After setting up the pole, extending the pole to the support rope and hooking the support rope, the C-type hook is in a vertical state, so it is easy to hook. When descending from the passenger carriage, the pole descends when the vertical angle is close to vertical. The pole must be opened diagonally because it enters the passage of the passenger and obstructs the descent. Since it is a joint connection, the pole can be moved freely. Since the bending force does not act directly on the pole post that moves obliquely while the weight is applied to the C-type hook, the bending does not occur unlike the old pole post.

[0006]

【Example】

 When the rescuer arrives directly below the rescue vehicle carrying the rescue equipment, the rescue equipment is as shown in Figure 1. 4. Relaxing device The telescopic pole 3. 3. C-shaped hook on the tip post Ring of 7. Telescopic pole attached to 3. Stand up and support this. Stretch towards. Then, the passenger who supported the C-type hook and tied up the rope and had the passenger on the transporter hang the belt of the lifting equipment under the armpits, and started the operation of descending from the transporter, but the pole was left as it was and the passenger descended. It is necessary to remove the lower part of the pole out of the passage because the pole is in the way and obstructs the pole. If the pole is opened with the weight of the passenger on the hook, the conventional structure would cause the pole, ring and hook to be linearly integrated and bend at the position of the ring. Here, in the present invention, the hook and the ring are made independent of the C type, and the ball joint is provided at the tip of the pole post with the cassette plate at the back of the main body. The pole can be freely opened at any angle while the weight is applied to the C-shaped hook.

[0007]

[Effect of the invention]

 In the present invention, a ring for hanging the lifting device is attached directly below the hook of the pole post used to rescue the passengers on the snow or on the ground, so that the pole can be rescued while the weight is on the hook. When the passengers escaped from the aisle, the hooks were pulled up from the upright position with the weight hung on the ring, and when the rescuing passenger was heavy, the pole tip was often bent, hindering rescue.

In the present invention, the hook and the ring are separated into a C-shape, and the cassette plate on the back of the main body is provided. 8. Ball joint at pole tip The pole can be freely opened at any angle while keeping weight on the C-shaped hook.

In addition, since the C-type hook is ball-jointed at the tip of the pole, if there is no load such as a loosening tool, the C-type hook is stiff when moving, so the ring at the lower end of the C-type hook and the pole post are pulled by a soft spring. As a result, the C-type hook is always softly fixed to the post, making it convenient to carry.
