[0001] The invention relates to a traction device, in particular to a traction fixed self-locking device capable of realizing multi-level protection and its application. Background technique
[0002] It is known that during the construction of the derrick, in order to ensure the stability of the derrick, it is usually necessary to fix the derrick guy rope on the derrick, and in order to enable the guy rope to effectively pull and limit the derrick, the guy rope needs to be tightened and straightened. The traditional The method is to use turnbuckle screws to realize the tightening of the stay ropes. However, due to the short adjustment distance and slow adjustment speed of the turnbuckle screws, it takes about 20 minutes for each stay rope to be adjusted by three people. The radial torque generated when the turnbuckle adjusts the stay rope will cause the bolts of the threaded buckle to loosen, which increases the safety hazard. At present, a traction fixed sel...
