Description
Boring winches are the main mechanism of a hoisting complex of the drilling rig. Boring winches are intended for performance of the following operations of technological process of construction of wells:
- descent and raising of boring pipes;
- descent of upsetting pipes;
- giving of the tool on a face;
- rotation transfer to a rotor in the absence of the individual drive of a rotor;
- emergency raising of the tool.
Design features and advantages:
Boring winches are completed with the regulator of giving of a chisel on a face, the additional drive of the winch provides rise and lowering of a tower at installation and dismantle of the drilling rig.
The design of the winch allows to carry out raising of the boring tool with simultaneous rotation of a rotor.
System of pipelines of greasing and air are entered in a design of the winch and allow to carry out maintenance of the equipment of winches.
Switching of speeds in a transmission, inclusion and shutdown of an auxiliary brake and the regulator of giving of a chisel is made by means of the switching mechanism.
