[0023] refer to Figure 3 and Figure 4 The moving assembly 4 includes a moving block 9, which is arranged on the front side of the rotating plate 6. The outer surface of the moving block 9 is slidably connected to the inner wall of the moving groove 601. The front side of the moving block 9 is fixedly connected with a toggle block 10, and the back side of the moving block 9 is provided with a moving rod 11.
[0024] The above solution is adopted: by setting the moving block 9, when the toggle block 10 is pushed upward, it can drive the moving block 9 to slide upward in the moving groove 601, thereby synchronously driving the moving rod 11 to move.
[0025] refer to Figure 4 The moving rod 11 is arranged on the inner wall of the slot 8 , the front side of the moving rod 11 is fixedly connected to the back side of the moving block 9 , and the moving rod 11 cooperates with the limiting assembly 5 .
[0026] The above solution is adopted: by arranging the moving rod 11, the moving rod 11 can respectively squeeze the two linkage arms 12 during the movement, thereby driving the operation of the limiting assembly 5.
[0027] refer to Figure 4 The limiting assembly 5 includes two linkage arms 12, both of which are arranged on the inner wall of the slot 8, and the middle of the two linkage arms 12 are rotatably connected to the inner wall of the slot 8 through a rotating shaft. The two linkage arms 12 are respectively arranged opposite to each other on the left and right, and the bottoms of the two linkage arms 12 are respectively fitted with the outer surface of the moving rod 11, and the tops of the two linkage arms 12 are respectively fixedly connected with linkage rods 13, and the outer surfaces of the two linkage rods 13 are respectively sleeved with moving arms 14, and the rear sides of the two linkage arms 12 are provided with sliding arms 15.
[0028] The above scheme is adopted: by setting the linkage arm 12, the moving rod 11 can squeeze the bottom of the two linkage arms 12 respectively during the upward movement, thereby driving the two linkage arms 12 to rotate relative to each other. The rotation of the two linkage arms 12 drives the two linkage rods 13 to move away, thereby cooperating with the sliding arm 15 to drive the two moving arms 14 to move away.
[0029] refer to Figure 4 The sliding arm 15 is arranged at the rear side of the two linkage arms 12 , and the back side of the sliding arm 15 is fixedly connected to the rear side of the inner wall of the slot 8 , and the sliding arm 15 cooperates with the two moving arms 14 to work.
[0030] The above solution is adopted: by providing the sliding arm 15 , the sliding arm 15 can provide a horizontal stroke for the two movable arms 14 , so that the two movable arms 14 can move in the horizontal direction.
[0031] refer to Figure 4, the backs of the two moving arms 14 are respectively slidably connected to the surfaces of the sliding arms 15. Linkage grooves 16 are respectively formed on the fronts of the two moving arms 14. The inner walls of the two linkage grooves 16 are respectively in contact with the outer surfaces of the two linkage rods 13. Fixing springs 17 are respectively fixedly connected to the sides of the two moving arms 14 away from each other. The ends of the two fixing springs 17 away from each other are respectively fixedly connected to the inner walls of the slotted openings 8. Fixing blocks 18 are respectively arranged at the tops of the two moving arms 14.
[0032] With the above solution: By arranging the moving arms 14, when the two linkage rods 13 move, they can respectively press the inner walls of the two linkage grooves 16 to drive the two moving arms 14 to slide away on the surfaces of the sliding arms 15 respectively, and compress the two fixing springs 17 respectively. When the two moving arms 14 move, they drive the two fixing blocks 18 to move away respectively.
[0033] Reference Figure 4 , the two fixing blocks 18 are respectively fixedly connected to the sides of the tops of the two moving arms 14 close to each other. The ends of the two fixing blocks 18 close to each other are respectively inserted into the inner walls of the positioning grooves 701.
[0034] With the above solution: By arranging the fixing blocks 18, when the two fixing blocks 18 move away, they can respectively disengage from the positioning grooves 701 to release the fixed limit on the positioning block 7. In this way, the protective auxiliary plate 201 can be pushed back into the protective plate 2 through the handle 202.
[0035] The working principle of the present utility model:
[0036] When in use, the toggle block 10 is pushed upward, so that it drives the moving block 9 to slide up in the moving groove 601, and simultaneously drives the moving rod 11 to move upward. When the moving rod 11 moves, it squeezes the surfaces of the bottoms of the two linkage arms 12 at the same time, so as to drive the two linkage arms 12 to rotate relative to each other. The rotation of the two linkage arms 12 drives the two linkage rods 13 to move and move away respectively. During the movement of the two linkage rods 13, they squeeze the linkage grooves 16 respectively, thereby driving the two moving arms 14 to slide away on the surfaces of the sliding arms 15, and squeeze the compression of the two fixed springs 17 respectively. The two moving arms 14 slide away and then drive the two fixed blocks 18 to move away respectively, so that the two fixed blocks 18 are disengaged from the positioning grooves 701 to release the fixed limit of the positioning block 7. Subsequently, the protective sub-plate 201 can be pushed upward through the handle 202, so that the protective sub-plate 201 moves up together with the positioning block 7 and is retracted into the protective plate 2, and The protective plate 2 can be flipped backward as a whole to expose the two rollers 103, and then the rotating plate 6 can be flipped downward. At this time, the cable winding work can be carried out. After use, the rotating plate 6 is flipped upward to make it in a vertical state, and the protective plate 2 is flipped forward so that the protective plate 2 covers the outer ring of the roller 103, and then the protective sub-plate 201 is pulled downward by the handle 202, so that it synchronously drives the positioning block 7 to move downward and move the positioning block 7 into the slot 8, and the moving block 9 moves downward and squeezes the surfaces of the two fixed blocks 18 at the same time, so that the two fixed blocks 18 are squeezed to move away and drive the two moving arms 14 to slide away. As the positioning block 7 moves downward, the two moving arms 14 are pushed closer by the fixed spring 17, and drive the two fixed blocks 18 to be respectively inserted into the positioning groove 701 to fix and limit the positioning block 7, so that the protective sub-plate 201 is fixedly connected with the rotating plate 6 to protect the roller 103.
[0037] To sum up: the double-drum cantilever gun cable winch, through the coordinated work of the base 1, the protective plate 2, the positioning structure 3, the moving component 4 and the limiting component 5, solves the problem that when the double-drum cantilever gun cable winch is idle, if it is not properly protected, its internal mechanical parts such as gears and bearings are easily invaded by dust and impurities, resulting in increased wear, which not only affects the normal startup and operation of the winch, but even causes more serious mechanical failures.
