Description

Technical Field

[0001] This utility model relates to the field of fire rescue technology, specifically a multi-functional rope for helicopter fire rescue. Background Technology

[0002] Urban firefighting is a preventive and disaster reduction measure taken to prevent and mitigate the losses caused by fire to cities. Currently, due to the height of buildings and complex layouts in cities, helicopter assistance is required during firefighting. Rescue ropes and safety ropes are essential equipment for fire rescue. They are mainly used by firefighters for personal escape and self-rescue during firefighting, rescue, disaster relief, and daily training. They can also be used for auxiliary work such as rescuing people and hoisting equipment, but are limited to single-person use.

[0003] For example, the utility model patent with publication number CN212709980U discloses a multi-functional rope for helicopter fire rescue. In view of the problem that the existing rescue ropes have only one function, the following solution is proposed: it includes a triangular head, the top of which has an installation groove, a red warning light is movably installed in the installation groove, and connecting blocks located in the installation groove are fixedly installed on both sides of the red warning light. The two connecting blocks have a slot on the side that is far away from each other. The triangular head has an installation cavity, which is located directly below the installation groove. The top inner wall of the installation cavity has a first groove on both sides. This utility model has a simple structure and reasonable design. The rescue rope can not only be used for auxiliary work such as rescuing people and hoisting equipment, but also emits red light in low-light environments to help trapped people find the rescue rope. This solves the problem of the single function of existing ropes and improves the practicality of the rope. However, there is a problem that the locking lever will interfere with the connecting block and the inner end of the second groove during the movement. This will cause the locking lever to get stuck when installing or removing the red warning light, resulting in inconvenience and difficulty in installing or removing the red warning light. Therefore, we propose a multi-functional rope for helicopter fire rescue. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5This utility model provides a technical solution: a multi-functional rope for helicopter fire rescue, including an installation block 1, a placement cavity 6 at the inner end of the installation block 1, an installation groove 2 at the middle of the upper end of the installation block 1, a warning light assembly 3 at the inner end of the installation groove 2, two symmetrically arranged placement grooves 4 at the lower end of the installation block 1, the placement grooves 4 communicating with the placement cavity 6, a contact wheel assembly 5 on the inner wall of the placement groove 4, a sliding groove 7 on the installation block 1 communicating with the inner side wall of the placement cavity 6, a rope pulling and clamping mechanism 8 at the inner end of the placement cavity 6, the rope pulling and clamping mechanism 8 for clamping the warning light assembly 3, the contact wheel assembly 5 for guiding the rope body 88, and the warning light assembly 3 for warning purposes.

[0023] In this embodiment, the rope pulling and clamping mechanism 8 includes two symmetrically arranged rotating wheels 81. A follower shaft 82 is fixedly installed on the surface of the rotating wheels 81. Two symmetrically arranged rotating gears 83 are fixedly installed on the outer end of the follower shaft 82. A movable rack 84 is meshed with the upper end of each rotating gear 83. A slide groove 7 is slidably connected to the outer end of each movable rack 84. A post 85 is fixedly installed on the inner end of each movable rack 84. A return spring 86 is fixedly installed on the end of the movable rack 84 away from the post 85. The outer end of the return spring 86 is fixedly connected to the inner wall of the mounting block 1. A rope body 88 is wound around the outer end of each rotating wheel 81. Each rope body 88 passes through the placement groove 4.

[0024] Specifically, in use, the pull ring 87 can be pulled downwards, causing the two symmetrically arranged rope bodies 88 to move downwards. At this time, each rope body 88 drives the rotating wheel 81 to rotate, which in turn drives the follower shaft 82 to rotate, which in turn drives the rotating gear 83 to rotate. Each rotating gear 83 drives the moving rack 84 to move, and each moving rack 84 drives the insertion post 85 to move. During this movement, the insertion post 85 disengages from the insertion hole 33, and the warning light assembly 3 can then be removed from the mounting slot 2 for easy installation and removal. During this process, the moving rack 84 always slides on the inner wall of the slide groove 7.

[0025] In this embodiment, the warning light assembly 3 includes a warning light body 31. Both sides of the warning light body 31 are fixedly installed with fixing strips 32. Each of the two fixing strips 32 has two symmetrically arranged insertion holes 33 at one end away from each other.

[0026] Specifically, the warning light component 3 can be used to perform warning actions to provide a reminder effect.

[0027] In this embodiment, the contact wheel assembly 5 includes a contact shaft 51. Both ends of the contact shaft 51 are rotatably connected to the inner wall of the placement groove 4 through bearings. A contact wheel body 52 is fixedly installed at the middle of the outer end of the contact shaft 51, and the outer end of the rope body 88 abuts against the contact wheel body 52.

[0028] Specifically, through the rope body 88 and the contact wheel assembly 5, the rope body 88 is always in contact with the contact wheel body 52 during the pulling process. The contact wheel body 52 provides support for the rope body 88 during the pulling process, thereby improving the stability of the rope body 88 during the pulling process.

[0029] In this embodiment, the follower shaft 82 passes through the rotating wheel 81, and both ends of the follower shaft 82 are rotatably connected to the mounting block 1 through bearings.

[0030] Specifically, ensure that the follower shaft 82 does not interfere with the mounting block 1 during rotation.

[0031] In this embodiment, a pull ring 87 is fixedly installed between the tail ends of the two rope bodies 88, and the pull ring 87 is located at the lower part of the mounting block 1.

[0032] Specifically, the pull ring 87 directly performs work on the two symmetrically arranged rope bodies 88.

[0033] In this embodiment, the insertion post 85 is inserted into the insertion hole 33. The outer diameter of the insertion post 85 is matched with the inner diameter of the insertion hole 33, and the outer diameter of the insertion post 85 is matched with the inner height of the sliding groove 7.

[0034] Specifically, ensure that there is no interference when the plug 85 is plugged into the socket 33.

[0035] Working principle: In use, the pull ring 87 can be pulled downwards directly. The pull ring 87 drives the two symmetrically arranged rope bodies 88 to move downwards. At this time, each rope body 88 drives the rotating wheel 81 to rotate. The rotating wheel 81 drives the follower shaft 82 to rotate, which in turn drives the rotating gear 83 to rotate. Each rotating gear 83 drives the moving rack 84 to move. At this time, each moving rack 84 drives the insertion post 85 to move. During this movement, the insertion post 85 disengages from the insertion hole 33. Then, the warning light assembly 3 can be removed from the mounting slot 2 for convenient installation and removal. During this process, the moving rack 84 always slides on the inner wall of the slide groove 7.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
