[0027] The following is combined with Figure 1-4 The utility model is described in further detail.

[0028] Please refer to the attached figure in the instruction manual Figure 1-4 The utility model provides an embodiment: a rotation limit installation device, including a central steel pipe 1, a connecting block 5 is connected to the outer side of the central steel pipe 1, and a movable block 9 is connected through the connecting block 5 to facilitate the adjustment of the position of the movable block 9. A first threaded nail 6 is connected to the right side of the connecting block 5, and a bolt 7 is connected to the outer side of the first threaded nail 6. The first threaded nail 6 cooperates with the bolt 7 to complete the limit adjustment of the connecting block 5, and the other side of the connecting block 5 is connected to the movable block 9;

[0029] Second threaded nails 10 are connected to both sides of the movable block 9, and the mounting block 8 is limited by the second threaded nails 10 to ensure its easy installation. A threaded sleeve 11 is sleeved on the other side of the second threaded nail 10, and the second threaded nail 10 also passes through the mounting block 8. A touch ruler 4 is connected to the outside of the mounting block 8. The touch ruler 4 is used in conjunction with the limiter 3 to limit the crane to ensure its use. A limiter 3 is arranged on the outside of the touch ruler 4, and the limiter 3 is located inside the upper beam 2.

[0030] See the attached drawings in the specification Figure 1-4 The connection method between the central steel pipe 1 and the lower cross beam is hot-melt connection, the connection method between the central steel pipe 1 and the connecting block 5 is sliding connection, and the connection method between the connecting block 5 and the first threaded nail 6 is threaded connection. The first threaded nail 6 cooperates with the connecting block 5 to assist in the installation of the touch ruler 4, and it is convenient to adjust the angle and position of the touch ruler 4.

[0031] See the attached drawings in the specification Figure 1-4 The upper crossbeam 2 has limiters 3 symmetrically distributed inside. The limiters 3 are symmetrically distributed on both sides of the impact ruler 4. The angle between the limiters 3 is 180°. The upper crossbeam 2 and the limiters 3 are installed in an integrated manner. The limiters 3 cooperate with the impact ruler 4 to prevent the central steel pipe 1 from moving too much, thereby achieving the purpose of protecting the upper crossbeam 2.

[0032] See the attached drawings in the specification Figure 1-4 The connection between the touch ruler 4 and the mounting block 8 is a hot-melt connection. Arc-shaped protrusions are provided on both sides of the touch ruler 4. The movable angle of the touch ruler 4 is 130°. The rotation position of the touch ruler 4 contacts the limiter 3. The mounting block 8 is used to limit and fix the touch ruler 4, ensuring that the touch ruler 4 can adapt to the limiter 3 at any position, so that the touch ruler 4 can be installed quickly and conveniently.

[0033] See the attached drawings in the specification Figure 1-4 The inner side of the mounting block 8 is evenly and equidistantly distributed with second threaded nails 10. The second threaded nails 10 are connected to the threaded sleeve 11 by threaded connection. The threaded sleeve 11 and the movable block 9 are engaged with each other. The movable block 9 cooperates with the threaded sleeve 11 to limit the installation of the second threaded nail 10 while avoiding wear of the thread during the disassembly process, thereby ensuring repeated use.

[0034] See the attached drawings in the specification Figure 1-4 The movable block 9 fits tightly with the central steel pipe 1. The movable block 9 forms an integrated installation structure with the central steel pipe 1 through the connecting block 5. The connecting block 5 forms a threaded connection structure with the first threaded nail 6 and the bolt 7. A shock-absorbing gasket is arranged between the bolt 7 and the first threaded nail 6. The bolt 7 cooperates with the gasket to ensure the fixation of the first threaded nail 6 and ensure the firm connection between the connecting block 5 and the first threaded nail 6.

[0035] Working principle: When in use, first, according to the position of the limiter 3, pull the movable block 9 so that the movable block 9 moves at the position of the central steel pipe 1. The movable block 9 drives the mounting block 8 to move during the movement, so that the touch ruler 4 moves together until the touch ruler 4 and the limiter 3 are at the same horizontal line. Then, stop moving the movable block 9 and tighten the first threaded nail 6 at the same time, so that the first threaded nail 6 tightens the connecting block 5, so that the connecting block 5 and the central steel pipe 1 are fixed. At the same time, fix the gasket and the bolt 7 on both sides of the first threaded nail 6 to complete the fixing work. When the touch ruler 4 needs to be repaired, remove the second threaded nail 10, release the fixation of the movable block 9 and the mounting block 8, and the disassembly and repair work can be completed.

[0036] As mentioned above, when in use, the lower cross beam drives the central steel pipe 1 to rotate during rotation, so that the central steel pipe 1 drives the connecting block 5 and the movable block 9 to rotate, so that the mounting block 8 and the touch ruler 4 also rotate. When the touch ruler 4 rotates to the position of the limiter 3, the touch ruler 4 triggers the limiter 3, causing the lower cross beam to stop rotating.

[0037] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
