Description

Technical Field

[0001] This utility model belongs to the technical field of rope and cable fixing structure, specifically relating to a quick fixing device for helicopter rescue ropes and cables. Background Technology

[0002] Helicopter rescue utilizes helicopters for emergency rescue, enabling them to reach work sites that are difficult to access by water or land more quickly, and to carry out search and rescue, material transportation, and aerial command and control.

[0003] The current rescue method involves lowering rescue equipment or supplies based on the actual situation on site. However, this requires rescuers to secure the supplies and equipment in advance using rescue ropes. Rescuers need to quickly tie the ropes and ensure the secureness of the connection between the ropes and the equipment. This tying process greatly affects the speed of the rescue operation. Utility Model Content

[0004] The purpose of this utility model is to provide a simple and reasonably designed quick-fixing device for helicopter rescue ropes in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A helicopter rescue rope quick-fixing device includes two symmetrically arranged side plates, with a frame-like edging between the two side plates. The two side plates are fixed by the edging, forming a receiving cavity between the two side plates and the edging. Two sets of limiting wheels are symmetrically arranged within the receiving cavity, with a gap between the two limiting wheels in each set. A connecting shaft is eccentrically mounted at both ends of each limiting wheel. The end of the connecting shaft away from the limiting wheel passes through the side plate and is rotatably connected to the side plate. An adjustment structure is installed at the end of the connecting shaft outside the receiving cavity. A rescue rope is arranged below the side plates, with both ends of the rescue rope passing through the gap between the two limiting wheels and extending above the edging. A ball head is fixedly connected to the end of the rescue rope. The maximum gap between the two limiting wheels in each set is greater than the diameter of the rescue rope, and the minimum gap between the two limiting wheels in each set is less than the diameter of the rescue rope.

[0007] As a further optimization of this utility model, two ear plates are symmetrically connected to the upper surface of the perimeter, and a shackle for connecting to a helicopter is connected between the two ear plates.

[0008] As a further optimization of this utility model, the middle section of the limiting wheel is provided with an annular groove, and the inner wall of the groove is provided with anti-slip texture.

[0009] As a further optimization of this utility model, the adjustment structure includes a handle fixedly connected to one end of the connecting shaft outside the receiving cavity, and a magnetic ring fixedly sleeved on one end of the handle near the side plate, the magnetic ring being attached to the side plate and magnetically connected to the side plate.

[0010] As a further optimization of this utility model, two rope holes are provided on both the top wall and the bottom wall of the enclosure. The end of the rescue rope passes through the rope hole and passes through the enclosure. The diameter of the ball head connected to the end of the rescue rope is larger than the diameter of the rope hole.

[0011] As a further optimization of this utility model, two wear-resistant sleeves are fixedly connected to the bottom wall of the perimeter, the wear-resistant sleeves are sleeved on the rescue rope, and a reinforcing plate is fixedly connected between the top ends of the two wear-resistant sleeves.

[0012] The beneficial effects of this utility model are as follows: the end of the rescue rope is located in the gap between the two limit wheels in each group. The size of the rope loop formed by the rescue rope and the edge can be adjusted by pulling the end of the rescue rope to fix the materials. When the helicopter is transporting materials, the materials will pull the rescue rope and cause it to slide down under the action of gravity. At this time, the friction between the rescue rope and the limit wheel will drive the limit wheel to rotate and clamp the rescue rope to ensure the stability of the materials. This makes it easy for users to quickly fix the materials and transport them by helicopter. Attached Figure Description

[0018] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Example

[0020] like Figure 1 - Figure 4 As shown, a quick-fixing device for helicopter rescue ropes includes two symmetrically arranged side plates 1. The side plates 1 are made of a material that can be attracted by magnetic materials. A frame-like rim 2 is provided between the two side plates 1. The two side plates 1 are fixed by the rim 2, and the side plates 1 and the rim 2 are connected to form an integral structure.

[0021] Two ear plates 4 are symmetrically connected to the upper surface of the side panel 2. A shackle 5 for connecting with the helicopter is connected between the two ear plates 4. When in use, the shackle 5 can be removed from the two ear plates 4 and put on the connecting parts of the helicopter. Then the shackle 5 can be reinstalled on the ear plates 4, so that the overall structure formed by connecting the side plate 1 and the side panel 2 can be connected to the helicopter.

[0022] A receiving cavity 3 is formed between the two side plates 1 and the surrounding edge 2. Two sets of limiting wheels 6 are symmetrically arranged in the receiving cavity 3. A gap is left between the two limiting wheels 6 in each set. A groove 8 with an annular structure is opened in the middle section of the limiting wheel 6. Anti-slip texture is opened on the inner wall of the groove 8. By setting anti-slip texture in the groove 8, the anti-slip performance of the limiting wheel 6 can be greatly improved.

[0023] Both ends of the limiting wheel 6 are eccentrically mounted with connecting shafts 7. Since the limiting wheel 6 is eccentrically set, the two limiting wheels 6 in each group can rotate around the connecting shaft 7 to adjust the distance between the two limiting wheels 6.

[0024] One end of the connecting shaft 7 away from the limiting wheel 6 passes through the side plate 1 and is rotatably connected to the side plate 1. An adjustment structure is installed at the end of the connecting shaft 7 outside the receiving cavity 3. The adjustment structure includes a handle 9 fixedly connected to the end of the connecting shaft 7 outside the receiving cavity 3. A magnetic ring 10 is fixedly sleeved at the end of the handle 9 near the side plate 1. The magnetic ring 10 is attached to the side plate 1 and magnetically connected to the side plate 1. The handle 9 is provided so that the user can rotate the connecting shaft 7 to rotate the side of the connecting shaft 7, thereby driving the limiting wheel 6 fixed to the connecting shaft 7 to rotate and adjust the distance between the two limiting wheels 6 in each group. The magnetic ring 10 is provided to be attracted to the side plate 1 so that the connecting shaft 7 can be relatively fixed to the side plate 1 when no external force is applied.

[0025] A rescue rope 12 is provided below the side panel 1. Two rope holes 11 are opened on the top wall and bottom wall of the enclosure 2. The two ends of the rescue rope 12 pass through the two rope holes 11 opened on the bottom wall of the enclosure 2 and extend into the receiving cavity 3. Then, it passes through the gap between the two limit wheels 6 in each group and finally passes through the rope hole 1 opened on the top of the enclosure 2 and extends to the top of the enclosure 2.

[0026] The end of the rescue rope 12 is fixedly connected to a ball head 13, and the diameter of the ball head 13 connected to the end of the rescue rope 12 is larger than the diameter of the rope hole 11, which can minimize the risk of the end of the rescue rope 12 slipping off from above the edge 2.

[0027] The maximum distance between the two limiting wheels 6 in each group is greater than the diameter of the rescue rope 12, and the minimum distance between the two limiting wheels 6 in each group is less than the diameter of the rescue rope 12. When the two limiting wheels 6 in each group rotate to the maximum distance, the rescue rope 12 can slide within the gap formed between the two limiting wheels 6 in each group. When the inner wall of the groove 8 opened on the two limiting wheels 6 in each group rotates to fit against the outer surface of the rescue rope 12, it can clamp the rescue rope 12 and fix the rescue rope 12.

[0028] Two wear-resistant sleeves 14 are fixedly connected to the bottom wall of the perimeter 2. The wear-resistant sleeves 14 are fitted onto the rescue rope 12. A reinforcing plate 15 is fixedly connected between the top ends of the two wear-resistant sleeves 14. The wear-resistant sleeves 14 fitted onto the rescue rope 12 are used to protect the rescue rope 12 and minimize the friction between the rescue rope 12 and the inner edge of the threading hole 11 during sliding, which could easily lead to wear and breakage of the rescue rope 12. The reinforcing plate 15 is used to reinforce the two wear-resistant sleeves 14 and improve the stability of the installation of the wear-resistant sleeves 14.

[0029] It should be noted that, in use, this helicopter rescue rope quick-fixing device first involves turning the connecting shaft 7 by twisting the handle 9, which in turn rotates the limiting wheel 6 fixed to the connecting shaft 7, adjusting the distance between the two limiting wheels 6 in each group to the maximum. This allows the rescue rope 12 to slide within the gap between the two limiting wheels 6 in each group. Then, the supplies to be transported are placed in the rope loop formed by the rescue rope 12 below the perimeter 2. Pulling the rescue rope 12 upwards tightens it and secures the supplies. Once the rescue rope 12 is tightened, the user reverses the rotation of the handle 9. Adjust the distance between the two limit wheels 6 in each group until the inner wall of the groove 8 in the middle section of the limit wheel 6 fits against the rescue rope 12. At this point, the materials fixed in the loop of the rescue rope 12 can be transported by helicopter. Since the minimum distance between the two limit wheels 6 in each group is less than the diameter of the rescue rope 12, the weight of the materials will pull the rescue rope 12 downward during the hoisting process. This will cause the limit wheels 12 on both sides of the rescue rope 12 to rotate in opposite directions through the friction between the rescue rope 12 and the limit wheels 6, so as to clamp the rescue rope 12 and prevent it from loosening.

[0030] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
