RU95109138A - Device for moving and levelling of derrick unit of drilling rig - Google Patents

Abstract

FIELD: bore-hole drilling equipment. SUBSTANCE: this relates to bases adapted to movement in assembled state together with equipment mounted on it such as derrick unit from one bore-hole to another for drilling groups of bore-holes. Device has double-arm levers and each by its smaller arm is connected with frame. Mounted in middle part of each lever is wheel with axle functioning as fulcrum. Upper part of ram is connected with base. Wheel interacts with rails installed on guide beams. Frame in stationary position also interacts with guide beams. Under action of force produced by extending rods of rams, levers are turned relative to axes of wheels: large arm of levers moves down, and small arm moves up together with frame of derrick unit. Simultaneously, rods of rams acts on frame by force directed upwards. Frame is lifted relative to guide beams on which rails are mounted interacting with wheels. Device is provided with fixing mechanism made in the form of screw and nut pair located parallel to ram. One component of pair is installed on frame of base, and other component is installed on lever. EFFECT: high efficiency. 1 cl, 5 dwg

The invention relates to bases having the ability to move in assembled form with equipment placed on it, for example, a tower block when moving from well to well in drilling rigs for cluster drilling. The device is equipped with two-arm levers, each of which is pivotally connected to the frame by a smaller shoulder and a lower part of the jack with a large shoulder, a wheel is installed in the middle of each lever, the axis of which is the fulcrum. The upper part of the jack is connected to the base. The wheel interacts with the rails mounted on the guide beams, with which the frame can interact in the stationary position of the block. Under the action of the efforts of the extended jack rods, the levers rotate relative to the axles of the wheels: the larger arm of the levers will move down, and the smaller - up together with the frame of the tower block, while the jack rods act on the frame with the force directed upward. The frame is raised relative to the guide beams on which the rails are mounted, interacting with the wheels. The device is equipped with a locking mechanism made in the form of a screw pair located parallel to the jack, one of the elements of which is mounted on the base frame, and the other on the lever.
