Drilling rig winch large rope air resistance type rope remover

Abstract

The invention discloses an air-resistance type rope guide for guiding large steel rope of a boring winch. The air-resistance type rope guide is characterized in that a left rope support wheel and a right rope support wheel are sheathed on a left rope support wheel axle and a right rope support wheel axle, and sandwich a steel rope; a left piston and a right piston cannot move freely under the resistance of compressed air, so that the force applied to the left piston and the right piston by the compressed air is transferred to the left rope support wheel and the right rope support wheel to enable the rope support wheels to be arranged on a drum in sequence so as to prevent the steel rope on the drum from tangling. When the pressure providing compressed air pressure becomes larger in the field and cannot push the left piston and the right piston of the rope guider to move left and right stably along with the steel rope while winding and unwinding the steel rope below the weight of an empty runner wagon, the pressure can be lowered by adjusting a relief valve in front of an air inlet pipe of an air tank to ensure to bear against the left piston and the right piston of the rope guider to move stably while the winding and unwinding the wire rope on the drum below the weight of the empty runner wagon. In order to ensure the use safety and the service life, a gas-water separator, an atomized lubricator and the like are required below the air tank.

Description

technical field

[0001] The invention relates to the orderly arrangement of the steel wire ropes on the drum of the drilling rig in the process of lifting and lowering the car during oil drilling and workover, so that the steel wire ropes are not entangled and squeezed and damaged. Background technique

[0002] During oil drilling and workover, when the steel wire rope on the drilling rig drum is winding upwards, the brake operation is performed suddenly. Because there is no stable support resistance, the steel wire rope is arranged in sequence on the drum, so the steel wire rope is easy to get entangled on the drilling rig drum. Several kinds of drilling rig drum rope pullers used on site also cannot provide stable support resistance for the wound steel wire ropes. The steel wire ropes on the drum are easily entangled. When it is heavy, the entangled steel wire rope may be broken due to extrusion, which poses a great potential safety hazard. Contents of the invention [0...
