Description

Technical Field

[0001] This utility model belongs to the field of equipment maintenance technology in mines or tunnels, and specifically relates to a quick-repair tool for ventilation ducts. Background Technology

[0002] Underground ventilation ducts are important equipment in mine ventilation systems. Their main function is to transport fresh air from the surface to various working areas underground, meeting the oxygen needs of miners for breathing and equipment operation. At the same time, they also discharge harmful gases such as methane and carbon monoxide, as well as dust generated during underground operations, into the mine through the ventilation ducts, reducing their concentration underground and preventing accidents such as explosions and poisoning.

[0003] By properly arranging ventilation ducts, the direction and speed of airflow underground can be controlled, making ventilation more uniform and effective, and ensuring that each work point receives good ventilation.

[0004] When the ventilation duct is torn or damaged, it severely affects the normal air supply to the working face, leading to issues such as insufficient circulating air or insufficient air supply to the working face, thus impacting safe production. Because traditional ventilation duct repair tools use straight needles that cannot bend during the repair process, and when there is air inside the duct, the pressure is high, making it difficult to quickly and efficiently repair the torn duct. Utility Model Content

[0005] In order to solve at least one of the above-mentioned technical problems in the prior art, this utility model provides a quick repair tool for air ducts.

[0006] This utility model is achieved by the following technical solution: a quick repair tool for a blower, comprising a spiral structure and an auxiliary rotating structure, wherein the tip of the spiral structure is provided with a thread hole for inserting the repair thread, and the tail of the spiral structure is provided with an auxiliary rotating structure for assisting the spiral structure to rotate so that the tip of the spiral structure can quickly shuttle back and forth on both sides of the blower hole along its length, thereby alternately inserting the repair thread into both sides of the blower hole.

[0007] Preferably, the spiral structure is a steel spring, the tip of the spiral structure is conical, and the end of the conical shape is provided with a thread hole.

[0008] Preferably, the length of the spiral structure is greater than the length of the rupture opening in the air duct.

[0009] Preferably, the auxiliary rotating structure is laterally fixed at the tail of the spiral structure, and the auxiliary rotating structure is a straight steel bar welded to the spiral structure.

[0010] Compared with the prior art, the beneficial effects of this utility model are: This utility model employs a unique structural design that solves the problem of traditional ventilation duct repair tools struggling to connect long tears. It enables rapid closure of tears and is suitable for emergency support and rapid response at various work sites where ventilation ducts provide air supply. Simultaneously, it facilitates rapid and effective bonding of the tear surface later (adhesive bonding), allowing the repaired ventilation duct to continue meeting on-site work requirements.

[0014] The technical solutions of the present utility model will be clearly and completely described in conjunction with 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 implementation methods obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0015] It should be noted that the structures, proportions, sizes, etc., shown in the accompanying drawings of this specification are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed in the specification, and are not intended to limit the conditions under which this utility model can be implemented. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportional relationships, or adjustments to the size, without affecting the effects and purposes that this utility model can produce, should fall within the scope of the technical content disclosed in this utility model. It should be noted that in this specification, relational terms such as "first" and "second" are only used to distinguish one entity from several other entities, and do not necessarily require or imply any actual relationship or order between these entities.

[0016] This utility model provides an embodiment: like Figures 1 to 3As shown, a quick repair tool for a blower includes a spiral structure 1 and an auxiliary rotating structure 2. The tip of the spiral structure 1 is provided with a thread hole 101 for threading the repair thread. The tail of the spiral structure 1 is provided with an auxiliary rotating structure 2 for assisting the spiral structure 1 to rotate so that the tip of the spiral structure 1 can quickly shuttle back and forth on both sides of the blower hole along its length, alternately threading the repair thread into both sides of the blower hole.

[0017] In this embodiment, the spiral structure 1 is a steel spring. The tip of the spiral structure 1 is conical, and a threading hole 101 is provided at the end of the conical end. The length of the spiral structure 1 is greater than the length of the damaged opening in the air duct. The auxiliary rotating structure 2 is horizontally fixed to the tail of the spiral structure 1. The auxiliary rotating structure 2 is a straight steel bar welded to the spiral structure 1, serving as a rotating handle. This tool mainly consists of spiral structures 1 with different wire diameters, combined with the rotating handle at the bottom. A threading hole 101 is drilled at the top, and the tip of the needle is sharpened to form a new type of quick air duct repair tool. This tool can solve the problem that straight needles cannot bend during daily air duct repair. Moreover, it can select corresponding quick repair tools with different wire diameters and lengths according to the length of the air duct tear. In situations where it is not possible to replace the air duct with a new one in time or to save resources, it can quickly handle the situation and save air duct materials.

[0018] This structure uses steel spring spirals of varying wire diameters instead of straight needles to shuttle back and forth on both sides of the duct tear, alternately threading the patching thread through both sides of the tear to quickly, effectively, and pressure-resistantly close the tear. After quickly and conveniently patching the tear, it is then secured with special adhesive, saving material waste from replacing the duct and ensuring a reliable air supply to the work area.

[0019] Operating steps: During use, simply insert the mending thread 3 into the thread hole 101, align the tip with one side of the duct opening, and insert it while turning it out the other side. By alternating rotations, the mending thread 3 can be inserted alternately into both sides of the duct opening. After all the threads have been rotated and sewn, leave the thread end, reverse the spiral and pull it out, and then tie a knot in the mending thread 3 to complete the mending operation.

[0020] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
