Description

Technical Field

[0001] This utility model relates to the field of runway leveling technology, specifically a rapid assembly-type runway leveling mechanism for emergency repairs. Background Technology

[0002] In modern warfare, airport runways are core infrastructure for air power projection, combat support, and material resupply. Their survivability and rapid recovery capabilities directly affect the initiative on the battlefield. During wartime, the enemy often uses precision-guided weapons and bunker-buster munitions to target runways, causing severe damage such as craters, cracks, and collapses on the runway surface. In some areas, the damage can even be complex, with significant elevation differences and scattered debris, making it impossible for aircraft to take off and land normally and directly cutting off the air combat link.

[0003] Existing track leveling mechanisms often use overlapping plates and fixing bolts to connect two leveling plates. In this process, the fixing bolts need to be driven into the holes between the overlapping plates and the leveling plates one by one, which is time-consuming and labor-intensive and not conducive to the rapid assembly of usable temporary track.

[0004] Therefore, a rapid assembly-type runway leveling mechanism is needed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a quick-assembly runway leveling mechanism for emergency repairs, in order to solve the problem mentioned in the background art that the existing runway leveling mechanisms are time-consuming and labor-intensive during assembly.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A rapid-assembly runway leveling mechanism for emergency repair includes a leveling plate and splicing holes disposed thereon. Adjacent leveling plates are connected by a splicing mechanism, and the splicing mechanism includes an embedded protrusion for penetrating the splicing hole. The end of the embedded protrusion penetrating the splicing hole has an open structure, and a limiting protrusion extends movably into the open structure of the embedded protrusion. A limiting mechanism for restricting the rotation of the limiting protrusion is installed on the splicing mechanism.

[0008] Furthermore, the splicing mechanism also includes a lower mating plate for fixing the embedded protrusion, and a corresponding upper mating plate is provided above the lower mating plate, with the limiting protrusion installed on the lower surface of the upper mating plate.

[0009] Furthermore, both the upper and lower mating plates are provided in two models, and the limiting protrusion on the lower surface of the upper mating plate and the corresponding embedding protrusion on the upper surface of the lower mating plate are provided in a one-to-one correspondence. The limiting protrusion is provided through the upper mating plate by a damping bearing, and the embedding protrusion is connected to the upper surface of the lower mating plate by a bearing. A torsion spring is also provided between the embedding protrusion and the corresponding lower mating plate.

[0010] Furthermore, the splicing mechanism also includes two limiting blocks that are centrally symmetrically arranged within the embedded protrusion opening structure. Two locking blocks are centrally symmetrically arranged on the outer side of the limiting protrusion, and the locking blocks are arranged in a one-to-one correspondence with the embedded protrusion.

[0011] Furthermore, the downward-facing surface of the insert block and the upward-facing surface of the embedded protrusion are mutually matching inclined arc surfaces, and the upward-facing surface of the insert block and the downward-facing surface of the embedded protrusion are horizontal surfaces.

[0012] Furthermore, the limiting mechanism also includes a groove on the upper surface of the upper mating plate, and the upper end of the limiting protrusion extends into the upper surface of the upper mating plate. A cover plate is inserted into the groove, and a limiting buckle is provided on the lower surface of the cover plate.

The cover plate is provided with reserved holes that correspond one-to-one with the limiting protrusions, and the upper end of the limiting protrusions extends movably into the corresponding reserved holes.

[0022] 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 scope of protection of the present utility model.

[0023] Please see Figure 1-7 This utility model provides a technical solution:

[0024] A rapid-assembly runway leveling mechanism for emergency repair includes a leveling plate 1 and splicing holes 2 disposed thereon. Adjacent leveling plates 1 are connected by a splicing mechanism, which includes an embedding protrusion 6 for penetrating the splicing hole 2. The end of the embedding protrusion 6 penetrating the splicing hole 2 is open, and a limiting protrusion 10 extends movably into the opening of the embedding protrusion 6. The splicing mechanism also includes a lower connecting plate 5 for fixing the embedding protrusion 6, and a corresponding upper connecting plate 3 is disposed above the lower connecting plate 5. The limiting protrusion 10 is installed on the lower surface of the upper connecting plate 3. Both the upper connecting plate 3 and the lower connecting plate 5 are provided in two models, and the limiting protrusion 10 on the lower surface of the upper connecting plate 3 and the corresponding upper connecting plate 5 are connected in a specific manner. The embedded protrusions 6 on the upper surface of the lower docking plate 5 are set one-to-one. The limiting protrusions 10 are set through the upper docking plate 3 via damping bearings. The embedded protrusions 6 are connected to the upper surface of the lower docking plate 5 via bearings. A torsion spring 13 is also set between the embedded protrusions 6 and the corresponding lower docking plate 5. The splicing mechanism also includes two limiting blocks 7 centrally symmetrically arranged in the opening structure of the embedded protrusions 6. Two locking blocks 12 are centrally symmetrically arranged on the outer side of the limiting protrusions 10. The locking blocks 12 are set one-to-one with the embedded protrusions 6. The downward surface of the locking blocks 12 and the upward surface of the embedded protrusions 6 are mutually matching inclined arc surfaces. The upward surface of the locking blocks 12 and the downward surface of the embedded protrusions 6 are horizontal surfaces.

[0025] The splicing mechanism is equipped with a limiting mechanism for restricting the rotation of the limiting protrusion 10. The limiting mechanism also includes a plate groove 8 set on the upper surface of the upper docking plate 3, and the upper end of the limiting protrusion 10 extends into the upper surface of the upper docking plate 3. A cover plate 4 is inserted into the plate groove 8, and a limiting buckle 14 is provided on the lower surface of the cover plate 4. Four limiting right-angle blocks 11 are provided on the part of the limiting protrusion 10 that extends into the plate groove 8, and the four limiting right-angle blocks 11 form a square structure. The cover plate 4 is provided with reserved holes 9 that correspond one-to-one with the limiting protrusion 10, and the upper end of the limiting protrusion 10 extends movably into the corresponding reserved hole 9.

[0026] In use, the embedded protrusion 6 on the lower mating plate 5 is inserted through the adjacent flat plate 1 to make a preliminary connection between the adjacent flat plates 1.

[0027] Then, the cover plate 4 is inserted into the plate groove 8 and slid a certain distance so that the limit buckle 14 is locked on the side of the corresponding limit right angle block 11, thereby limiting the limit right angle block 11 so that the limit protrusion 10 is limited and cannot rotate.

[0028] Then, the limiting protrusion 10 on the upper docking plate 3 is inserted into the inner side of the corresponding embedded protrusion 6. During the process, the contact between the inserting block 12 and the limiting block 7 will cause the embedded protrusion 6 to rotate and move by an angle first, and then be reset by the torsion spring 13, so that the inserting block 12 moves to the bottom of the corresponding limiting block 7, thereby connecting the upper docking plate 3 and the lower docking plate 5.

[0029] Because the upper connecting plates 3 are mutually restrained, the cover plates 4 are also mutually restrained, so that the cover plates 4 cannot be moved after splicing, thus ensuring the stability of the connection between the flat plates 1 and helping the temporary runway built to be used stably.
