Problems solved by technology

This kind of catwalk structure is the simplest, but the friction between the drilling tool and the V-shaped groove is large, and the protection of the drilling tool is not enough
The V-shaped groove in the lifting power catwalk can be lifted to a certain height, and the drilling tool placed in the V-shaped groove is lifted to a certain position along with the V-shaped groove, and then pushed to the wellhead by the special mechanism inside the V-shaped groove Relative position, this kind of catwalk is not suitable for deep well drilling rigs

Embodiment Construction

[0030] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0031] see figure 1 , the land deep well drilling rig energy-saving power catwalk of the present invention mainly includes a flap feeding mechanism 1, a horizontal push trolley 2, a flap return mechanism 3, a V-wheel lifting mechanism 4, a slope trolley 5, a lifting manipulator 6 and a drill Countertop V-wheel trolley7. The main body of the turning plate feeding mechanism 1 is driven by two hydraulic cylinders, one of which is connected by a double pin shaft, and the other hydraulic cylinder is connected by a rear flange. After the system is started, the two hydraulic cylinders of the turning plate feeding mechanism 1 act first. The hydraulic cylinder is stretched out so that the material turning device is raised to be flush with the slide surface of the catwalk, and the drill pipe reaches the slideway of the horizontal part of the catwalk. The stro...

Abstract

The invention provides a terrestrial deep drilling rig energy saving power catwalk, mainly consisting of a plate turnover feeding mechanism, a horizontal pushing trolley, a plate turnover back feeding mechanism, a V wheel lifting mechanism, a slope trolley, a lifting manipulator and a drilling platform surface V wheel trolley. The main body of the catwalk is divided into a horizontal pushing portion and a slope lifting portion, wherein the horizontal pushing portion is a single slideway, the slope lifting portion is a three-slideway, when a drill stem runs upward, only the middle slideway of the slope lifting portion is used, when the drill stem runs downward, the slideways on two sides of the slope portion are used. The catwalk can automatically realize a series of functions, i.e., the drill stem is released at a low position, the drill stem can go up to a drilling platform stably and get down from the drilling platform successfully, accordingly, the number of drillers is reduced, the labor intensity of workers is relieved, the time for making a connection is shortened, the well construction period and cost are reduced, and the energy can be saved greatly.

Description

technical field [0001] The invention relates to an energy-saving power catwalk for a land deep well drilling rig. Background technique [0002] The catwalk is an important part of the drilling rig string drainage system, which belongs to the conveying part. Through corresponding operations, the drill pipes, drill collars and other tools used for drilling can be transported to the drilling platform to complete the corresponding drilling process operations. Its structural layout The rationality and operability of drilling directly affect the speed, efficiency, stability, safety and reliability of drilling operations. In traditional drilling operations, drawworks and wire ropes are mostly used to realize the horizontal transmission of the drill string and the upper and lower drill floors. Drilling workers need to be in direct contact with the drill pipes, manual operation, low work efficiency, and great danger. [0003] With the increase of drilling depth, the demand for drill...
