When the drilling tool is stuck or blocked in the process of tripping, the top drive can be quickly connected with the drilling tool, and mud is circulated to carry out reaming operation. When the casing is put down, the casing is grabbed by means of the lifting ring tilting mechanism, and the top drive has a centralizing effect when the casing is buckled, so that the disordered buckling and the staggered buckling can be avoided, and the casing-lowering speed is greatly improved. In the directional drilling, a brake mechanism can be used for braking the top drive main shaft to perform directional deflecting. Therefore, the application of the top drive in drilling at home and abroad is more and more extensive.
However, with the wide application of the top drive, the special functions of the top drive hanging ring and the rotating head also cause some accidents during special operations. For example, when tripping operation is performed, a derrick worker is required to climb the racking platform, stand at the monkey platform and cooperate with a mechanical boom operated by a driller to complete operations such as screwing and unscrewing, taking and placing a stand, connecting the stand and the like. During actual top drive operation, due to misoperation of a driller, the extended top drive hanging ring cannot be restored in time after certain operation is completed, and when a traveling block moves up and down, the extended top drive hanging ring collides with a monkey stand where a derrick worker stands, so that serious safety accidents are caused. At present, domestic drilling machines are equipped with anti-collision brake systems, but some of the anti-collision brake devices do not have the function of preventing collision with a monkey, and some of the anti-collision brake devices do not have the function of preventing collision with a monkey although the anti-collision with a monkey, namely no matter whether the driller has misoperation, no matter whether the top drive hoisting ring is inclined and extended, as long as the traveling block reaches the position of the monkey, the anti-collision devices can take brake actions, and forcibly interrupt normal operation processes such as drilling and tripping.
