Technical Field
[0001] This utility model belongs to the field of mine emergency rescue, specifically relating to a backpack-type stretcher for underground mine emergency rescue. Background Technology
[0002] Mine rescue refers to the technical measures taken to quickly rescue victims and handle accidents after a mine disaster. To quickly and effectively handle sudden mine accidents, protect the lives of workers, reduce losses of national resources and property, equip miners with self-rescue skills, organize high-level rescue teams, and equip them with advanced rescue equipment, it is crucial to carry out rescue work effectively.
[0003] The emergency rescue environment in mines is characterized by confined spaces, complex geological structures, and a high risk of secondary disasters, placing stringent demands on the portability and functionality of rescue equipment. Current technology, particularly traditional folding stretchers, typically employs a fixed frame structure, resulting in excessively large storage volume. This makes them difficult to transport quickly in low-ceilinged tunnels, and they are prone to slipping on inclined tunnels or debris-strewn surfaces, easily causing secondary injuries to the rescued person due to stretcher displacement. Furthermore, the presence of a stretcher makes it difficult for rescuers to carry other rescue items.
[0004] Therefore, how to provide a portable backpack-style stretcher for emergency rescue in mines has become a problem that needs to be considered by those skilled in the art. Utility Model Content
[0005] In view of this, the present invention provides a backpack-style stretcher for emergency rescue in mines, which allows rescuers to carry the stretcher on their backs, freeing up their hands. The backpack-style structure also makes it convenient to carry other rescue items.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A backpack-style stretcher for emergency rescue in underground mines includes a main frame with a support fabric sewn onto it. A handle is sewn onto the edge of the support fabric covering the main frame, and a detachable strap is threaded through the handle. The main frame includes an outer support, a back support, and an inner support. Two shoulder straps are provided on the outer side of the back support. The bottom of the back support is hinged to the outer support via a first hinge assembly. The inner support is positioned between the outer support and the back support, and its top is hinged to the back support via a second hinge assembly. A canvas cover is provided at the hinge point of the inner support, and an inflatable pillow is sewn onto the outer side of the canvas cover. The canvas cover is adhered to the support fabric on the outer support.
[0008] Furthermore, the main body of the first hinge assembly is semi-cylindrical, and through hinge slots are provided at both ends of the first hinge assembly. The opening of the first hinge assembly faces away from the backpack, and the two side support rods of the external bracket and the back bracket are hinged to the ear plate of the hinge slot.
[0009] Furthermore, the second hinge assembly has the same structure as the first hinge assembly, and the length of the second hinge assembly is half the length of the first hinge assembly.
[0010] Furthermore, the inner side of the canvas cover is sewn with a hook and loop fastener, the supporting fabric of the outer bracket is correspondingly sewn with a first hook and loop fastener, and the supporting fabric of the inner bracket is correspondingly sewn with a second hook and loop fastener.
[0011] Furthermore, it also includes a first leg and a second leg. The first leg is cylindrical and is installed on the inner side of the support rods on both sides of the outer bracket. The bottom of the first leg abuts against the support rods on both sides of the inner bracket. The second leg is V-shaped and is installed in the middle of the support rods on both sides of the inner bracket. The second leg straddles the support rods on both sides of the back bracket.
[0012] Furthermore, the middle sections of the two shoulder straps are respectively provided with metal connectors and metal buckles.
[0013] Furthermore, it also includes a disposable air bottle and an inflation valve. A storage cavity is sewn on one side of the air pillow, and the disposable air bottle is placed in the storage cavity. The disposable air bottle is connected to the air pillow through the inflation valve.
[0014] Furthermore, it also includes an emergency rescue kit, an oxygen cylinder, and a breathing mask, which are housed inside the backpack.
[0015] The beneficial effects of this utility model are as follows: The backpack-style stretcher of this utility model can be easily carried by rescuers and can carry additional rescue supplies, freeing up the hands of rescuers. By adopting the setting of a multi-segment hinged main frame, it can be unfolded to form a rescue stretcher. The setting of an inflatable pillow makes it convenient for the rescued person to lie flat. The setting of handles makes it convenient for rescuers to hold. The detachable straps can be used to fix the body of the rescued person after lying down, preventing them from slipping off the rescue stretcher. The carrying straps, with the setting of metal plugs and metal buckles, can be used to assist in fixing the person's body. The setting of disposable air cylinders and air valves can reduce the weight of the backpack while achieving rapid inflation of the inflatable pillow. Attached Figure Description
