Description

Technical Field

[0001] This utility model relates to the technical field of mine rescue facilities, and in particular to an emergency rescue device for underground mines. Background Technology

[0002] Mine emergency rescue stretchers are rescue tools designed specifically for complex mine environments. In accidents such as gas explosions, stretchers help rescue team members quickly transfer the injured and reduce secondary injuries. They are an indispensable piece of equipment in mine rescue. Traditional rescue stretchers usually require two people to carry them to quickly move the injured out of the danger zone.

[0003] In the context of mine environments, due to the narrow rescue space, insufficient number of rescuers, and urgent rescue progress, double stretchers are not suitable for mine rescue missions. As for traditional transport vehicle-type rescue stretchers, they are bulky and heavy, making them inconvenient to carry. When used on mine tunnels with poor lighting and uneven ground, they are prone to tilting and violent shaking, affecting the stability of transporting the wounded. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Example 1: Please refer to Figures 1 to 6 :

[0027] This utility model proposes an emergency rescue device for underground mines, comprising: a rescue stretcher 1, with two sets of safety straps 2 on the top of the rescue stretcher 1; the frame of the rescue stretcher 1 is connected by two sets of folding connecting rods 3, the folding connecting rods 3 being composed of a first folding rod 301 and a second folding rod 302 connected by a hinge; a vertical frame 4 is installed at the bottom of the rear folding connecting rods 3; a swing shaft frame 5 is hinged to the lower end of the vertical frame 4; a directional connecting plate 403 is fixedly connected to each side of the vertical frame 4; a shaft frame swing plate 501 is fixedly connected to each side of the swing shaft frame 5; a directional balance spring 502 is fixedly connected to the outer end of the shaft frame swing plate 501; the upper end of the directional balance spring 502 is fixedly connected to the outer end of the directional connecting plate 403; a balance wheel axle 6 is fixedly connected to the lower end of the swing shaft frame 5; stretcher support wheels 7 are rotatably connected to both ends of the balance wheel axle 6; the upper surfaces of the two shaft frame swing plates 501 are parallel to the axis of the balance wheel axle 6; and the directional connecting plates 403 are connected to the vertical frame. The side of the stretcher 4 is perpendicular, and the vertical connecting frame 4 is perpendicular to the first folding rod 301. When operating by a single person, the stretcher handle 8 is manually lifted to drag the stretcher. When passing through uneven road sections or obstacles and pits, the stretcher support wheel 7 rolls over the obstacle, applying unilateral pressure to the balance wheel axle 6. Under the pressure, the lower end of the vertical connecting frame 4 of the swinging axle frame 5 tilts to one side, achieving a buffering effect and balancing the stretcher. This prevents the stretcher from shaking and tilting violently when passing through uneven road surfaces or obstacles, which could cause the injured person to fall and suffer secondary injuries. This improves the stability of the rescue. The directional balance tension spring 502 helps to keep the swinging axle frame 5 perpendicular to the rescue stretcher 1, keeping the stretcher stable. After shaking and tilting, the directional balance tension spring 502 restores the swinging axle frame 5 to its original angle. Single-person operation of the stretcher is more conducive to walking in the confined space and winding mine tunnels, making it suitable for emergency rescue.

[0028] In this embodiment, the inner end of the first folding rod 301 is fixedly connected to a first docking plate 303, and the inner end of the second folding rod 302 is fixedly connected to a second docking plate 304. The first folding rod 301 and the second folding rod 302 are aligned end-to-end in the unfolded state, and the first docking plate 303 and the second docking plate 304 are fitted together and fixedly connected by bolts. The first folding rod 301 and the second folding rod 302 are hinged to form a foldable folding link 3, which allows the rescue stretcher 1 to be folded, making it easy to store and carry. The bolt connection between the first docking plate 303 and the second docking plate 304 locks the angle between the first folding rod 301 and the second folding rod 302, so that the rescue stretcher 1 does not deform in the unfolded state.

[0029] In Example 2, based on Example 1, a rectangular opening structure connecting socket 401 is provided at the front of the vertical connecting frame 4. The connecting socket 401 is movably sleeved on the outside of the directional slot 305. The upper and lower edges of the opening of the connecting socket 401 are provided with limiting socket holes 402 with screw holes, and bolts are installed inside the limiting socket holes 402. The connecting socket 401 is slidably connected to the directional slot 305, and the opening of the connecting socket 401 is blocked by bolts, so that the vertical connecting frame 4 and the first folding rod 301 are fixedly connected. The vertical connecting frame 4 and the folding connecting rod 3 can be quickly disassembled and connected, which can realize the quick disassembly and assembly of the stretcher body and the auxiliary wheel frame. It can further reduce the weight and volume of the stretcher, making it easier to carry. It can be used for two-person cooperative lifting and rescue, with multiple forms and a wide range of applications.

[0030] The working principle of this embodiment is as follows: When conducting emergency rescue operations in confined mine tunnels with many sharp bends, rescuers carry a folded rescue stretcher 1 into the rescue area, locate the injured person, unfold the stretcher so that the first folding rod 301 and the second folding rod 302 are unfolded horizontally, and fix the first connecting plate 303 and the second connecting plate 304 together with bolts. The vertical connecting frame 4 is then installed onto the rear first folding rod 301, so that the opening of the connecting socket 401 is fitted onto the outside of the directional slot 305, and the vertical connecting frame 4 is fixedly installed by screwing bolts into the limiting socket 402. The injured person is then transferred to the rescue stretcher 1, and the injured person is further secured using the safety straps 2. The two stretcher handles 8 are then grasped to lift the stretcher. The stretcher support wheels 7 roll in contact with the ground. Rescuers pull the stretcher through the mine tunnel. When passing uneven sections, obstacles, or pits, the stretcher support wheels 7 roll over the obstacles, applying unilateral pressure to the balance wheel axle 6. This pressure causes the swing axle frame 5 to tilt to one side at the lower end of the vertical connecting frame 4, providing a buffer and balancing effect. This prevents the stretcher from shaking and tilting violently when passing uneven surfaces or obstacles, which could cause the injured to fall and suffer secondary injuries. This improves rescue stability. Under the action of the directional balance tension spring 502, the swing axle frame 5 returns to its original angle, keeping the stretcher stable. This facilitates the transfer and rescue of the injured in the confined space and winding mine tunnels.
