Abstract

The invention discloses a multi-gear direct-drive well drilling winch provided with two hydraulic motors. The multi-gear direct-drive well drilling winch provided with the two hydraulic motors comprises a winch body and a hydraulic control part. The hydraulic control part comprises a free wheel valve group and a double-speed valve group. The free wheel valve group and the double-speed valve group communicate with a hydraulic source. The winch body structurally comprises a roller assembly. Winch frames are symmetrically installed at the left end and the right end of the roller assembly. A protective cover is arranged on the peripheries of the two winch frames. A left hydraulic motor assembly is installed at the outer end of the winch frame on the left side and integrates a left braking mechanism with the left hydraulic motor. A right hydraulic motor assembly is installed at the outer end of the winch frame on the right side and integrates a right braking mechanism with the right hydraulic motor. An encoder is installed at the shaft end on the outer side of the right hydraulic motor. The multi-gear direct-drive well drilling winch provided with the two hydraulic motors is small in size, low in weight and easy to maintain; and up-shifting and down-shifting of four gears of the winch are achieved, and the working efficiency of the winch is improved.

Description

technical field [0001] The invention belongs to the technical field of petroleum drilling equipment, and relates to a multi-gear double hydraulic motor direct-drive drilling drawworks. Background technique [0002] The drawworks is the core component of the oil drilling rig. During the oil drilling process, it is not only responsible for various operations such as drilling tools, running casing, controlling drilling pressure, handling accidents, extracting core barrels, and testing oil. Lifting and lowering tasks of the derrick and the base, etc. At present, the common drilling winches are divided into two types: one is the mechanical drive chain transmission form, the disadvantages of this type of drawworks are the long transmission chain, huge mechanism, low transmission efficiency and high failure rate; the other is the electric drive gear transmission form, This type of product has the disadvantages of complex control system, high production cost, and difficult manufact...
