[0013] The utility model will be explained in detail below in combination with the drawings and specific embodiments. The embodiments are implemented on the premise of the technical scheme of the utility model, and detailed implementation modes and specific operation processes are given, but the protection scope of the utility model is not limited to the following embodiments.

[0014] Reference Figure 1 As shown in the figure, the utility model provides a kind of horizontal winding mechanism prevents over-rotation protection device, including winding drum 1, turntable 2, stop assembly 3, limit switch 4;Winding drum 1 is connected with turntable 2, winding drum 1 is equipped with the stop assembly 3 of preventing excessive rotation, winding drum 1 is equipped with the limit switch 4 of receiving stop assembly 3 signal;

[0015] Winding drum 1 top is equipped with winding drum platform 11, and the stop assembly 3 and limit switch 4 are arranged on winding drum platform 11;

[0016] The stop assembly 3 includes stop arm 31 and hydraulic cylinder 32;Stop arm 31 is connected with the drive shaft of hydraulic cylinder 32, and hydraulic cylinder 32 drives stop arm 31 to extend or retract;

[0017] The limit switch 4 includes first limit switch 41 and second limit switch 42, and the first limit switch 41 detects that stopper completely extends, and the second limit switch 42 detects that stopper completely retracts;

[0018] The bottom of turntable 2 is equipped with mechanical stop block 21, and mechanical stop block 21 and stop arm 31 are mutually blocked when extending to provide physical barrier to prevent excessive rotation;

[0019] Working principle and beneficial effects are:

[0020] When extending: when system needs stop assembly 3 to engage, hydraulic cylinder 32 starts, and stop arm 31 is pushed outwards. When stop arm 31 extends, second limit switch 42 (retraction detection) is first disabled, and it is confirmed that stop arm 31 is no longer in retracted position. Once completely extends, first limit switch 41 (extension detection) will trigger, and it is confirmed that stop assembly 3 has arrived, so that stop arm 31 and mechanical stop block 21 are mutually blocked to prevent the rotation of winding mechanism.

[0021] When retracted: The hydraulic cylinder 32 retracts the stop arm 31 while the system allows rotation. During retraction, the first limit switch 41 (extension detection) is deactivated first, confirming that the stop arm 31 has left the extended position. When the stop arm 31 is fully retracted, the second limit switch 42 (retraction detection) is activated, allowing the rotation of the tube mechanism to resume.

[0022] The two switches of the utility model must provide consistent feedback to continue any operation. If any switch fails or provides inconsistent feedback, the system will immediately stop to ensure safety. Even during power or system failure, the stop assembly 3 will be locked in place when extended. If any component fails, the stop assembly 3 prevents rotation by default, and the redundant system prevents over-rotation failure.
