[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0028] Referring to Figure 1-6 , a fourteen-frame heavy-duty speed reducer includes an input shaft 2 and an output shaft 3 arranged on the surface of a machine body 1, a mounting plate 4 arranged on the surface of the machine body 1, and hexagonal bolts 5 arranged on the surface of the mounting plate 4. An auxiliary component is arranged on the surface of the mounting plate 4; the inside of the auxiliary component includes a limiting plate 6 arranged on the surface of the mounting plate 4 and in contact with the bolts 5, and two placement grooves 7 are formed on the surface of the limiting plate 6. A return spring 8, a moving plate 9 and a fixing rod 10 are sequentially arranged in the placement groove 7 from right to left, and a pulling plate 11 is arranged on the surface of the moving plate 9; a connection groove 12 is formed on the surface of the mounting plate 4, and fixing holes 13 connected to the fixing rod 10 are respectively arranged on both sides of the inner wall of the connection groove 12. During use, both sides of the inside of the limiting plate 6 can be respectively moved to both side planes of the hexagonal bolt 5 to limit the bolt 5, avoiding loosening or dropping due to vibration. At the same time, the limiting plate 6 also needs to be moved into the connection groove 12, and through the action of the return spring 8, the moving plate 9 can drive the fixing rod 10 to move and move it into the fixing hole 13, thereby limiting the limiting plate 6. And the rope 16 tied to the surface of the limiting plate 6 can prevent the limiting plate 6 from being lost due to dropping. A through hole is formed on one side of the inner wall of the placement groove 7, and the fixing rod 10 passes through the through hole and is connected to the inside of the fixing hole 13.
[0029] Furthermore, the heights of the two placement grooves 7 on the surface of the limiting plate 6 are different. When the two fixing rods 10 are on the same straight line, it is easy to cause the limiting plate 6 to turn and move.
[0030] Furthermore, the cross-section of the limiting plate 6 is in a "U" shape, and the distance between the two sides inside the limiting plate 6 is in contact with the two side planes of the bolt 5. The two inner walls of the "U"-shaped limiting plate 6 can limit the hexagonal bolt 5 to avoid loosening of the bolt 5 due to vibration.
[0031] Furthermore, the inside of the auxiliary component also includes a groove 14 arranged at the bottom end inside the connection groove 12, and a rotating tube 15 is rotatably connected inside the groove 14. A rope 16 connected to the limiting plate 6 is wound on the surface of the rotating tube 15. The rope 16 mainly prevents the limiting plate 6 from dropping or being lost, and also facilitates prompting personnel to reset the dropped limiting plate 6 to limit the bolt 5.
[0032] Furthermore, a spring 17 and a positioning rod 18 are sequentially arranged inside the rotating tube 15 , and the positioning rod 18 is fixedly connected to the inner wall of the groove 14 , so that the rotating tube 15 can reel in the rope 16 by tonning the spring 17 .
[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
