Description

一种钻杆升降工具Drill pipe lifting tool 技术领域Technical field
本发明涉及一种钻井施工工具，特别涉及一种钻杆升降工具，属于钻井工具技术领域。The invention relates to a drilling construction tool, in particular to a drill pipe lifting tool, belonging to the technical field of drilling tools.
背景技术Background technique
钻杆是尾部带有缧纹的钢管，用于连接钻机地表设备和位于钻井底端钻磨设备或底孔装置。钻杆的用途是将钻探泥浆运送到钻头，并与钻头一起提高、降低或旋转底孔装置。钻杆必须能够承受巨大的内外压、扭曲、弯曲和振动。在油气的开采和提炼过程中，钻杆可以多次使用。每根钻杆的长度一般在九米左右。The drill pipe is a steel pipe with a crepe at the end for connecting the surface equipment of the drilling rig and the drilling equipment or bottom hole device at the bottom of the drilling. The purpose of the drill pipe is to transport the drilling mud to the drill bit and to raise, lower or rotate the bottom hole device with the drill bit. The drill pipe must be able to withstand large internal and external pressures, distortions, bends and vibrations. The drill pipe can be used multiple times during the oil and gas extraction and refining process. The length of each drill pipe is generally about nine meters.
每根钻杆的尾部均设有母缧纹，设置母螺纹的尾端头外径略大于钻杆正身的外径。当钻杆被放置在地面上时，由于钻杆尾端头接触地面，钻杆正身与地面之间存在一定间歇。在向钻杆母缧纹中旋接公接头时，必须要先将钻杆尾端抬离地面，否则公接头不好旋转，操作者的手部也不好握持。因此，在施工现场特别需要能将钻杆抬离地面的工具，钻杆被抬离地面后要能够保持稳定状态，防止在旋接头的过程中出现倒伏，导致人身伤害。Each tail of the drill pipe is provided with a mother ridge pattern, and the outer diameter of the tail end of the female thread is slightly larger than the outer diameter of the drill pipe body. When the drill pipe is placed on the ground, there is a certain interval between the drill pipe and the ground due to the tip end of the drill pipe contacting the ground. When screwing the male joint into the drill rod female crepe, the tail end of the drill rod must be lifted off the ground first, otherwise the male joint is not well rotated, and the operator's hand is not well held. Therefore, there is a special need at the construction site for the tool to lift the drill pipe off the ground. After the drill pipe is lifted off the ground, it must be able to maintain a stable state, preventing the lodging during the process of the screw joint, resulting in personal injury.
发明内容Summary of the invention
本发明的目的在于，克服现有技术中存在的问题，提供一种钻杆升降工具，可以很方便地将钻杆抬离地面，便于钻杆端部的母螺纹与接头旋接。The object of the present invention is to overcome the problems in the prior art and to provide a drill pipe lifting and lowering tool, which can conveniently lift the drill pipe off the ground and facilitate the screwing of the female thread of the end of the drill pipe with the joint.
为解决以上技术问题，本发明的一种钻杆升降工具，包括手柄，所述手柄的下端垂直焊接在撬板的角部，所述撬板呈矩形，所述撬板靠近手柄的长边上设有钻杆支撑口，所述钻杆支撑口为半圆形开口，所述半圆形开口的半径与钻杆的半径相适配。In order to solve the above technical problem, a drill pipe lifting and lowering tool of the present invention includes a handle, and a lower end of the handle is vertically welded to a corner of the seesaw, the seesaw is rectangular, and the seesaw is adjacent to a long side of the handle. A drill rod support opening is provided, the drill rod support opening is a semi-circular opening, and the radius of the semi-circular opening is adapted to the radius of the drill rod.
相对于现有技术，本发明取得了以下有益效果：当钻杆被放置在地面上时，设有母螺纹的钻杆尾端头接触地面，钻杆正身与地面之间存在一定间歇，将撬板水平插入至钻杆下方，半圆形开口对准钻杆，此时手柄垂直于地面朝上；然后转动手柄的上端向地面方向倒伏，撬板的半圆形开口向上升起卡住钻杆，随着手柄的继续向下转动，半圆形开口抬着钻杆正身逐渐升高。当撬板转动至垂直于地面时，钻杆升至最高，将手柄头部搁在地面上，撬板的半圆形开口与手柄共同形成稳定支撑，此时可以进行旋接头操作。接头安装完毕后，再反向旋转手柄，将钻杆放回地面上，然后将撬板抽出。Compared with the prior art, the present invention achieves the following beneficial effects: when the drill pipe is placed on the ground, the tail end of the drill pipe provided with the female thread contacts the ground, and there is a certain interval between the drill pipe and the ground. The plate is horizontally inserted under the drill pipe, the semicircular opening is aligned with the drill pipe, and the handle is perpendicular to the ground upward; then the upper end of the handle is turned to the ground direction, and the semicircular opening of the seesaw rises to catch the drill pipe As the handle continues to rotate downward, the semi-circular opening lifts the drill pipe and the body gradually rises. When the seesaw is rotated perpendicular to the ground, the drill pipe is raised to the highest position, and the handle head is placed on the ground. The semicircular opening of the seesaw and the handle form a stable support, and the screw joint operation can be performed at this time. After the joint is installed, rotate the handle in the opposite direction, put the drill rod back on the ground, and then pull out the jaw.
作为本发明的优选方案，所述钻杆支撑口的底部与所述撬板的另一条长边之间的距离为60mm～120mm。能够使钻杆的尾端离地面50mm左右，足够进行旋接头操作。 As a preferred embodiment of the present invention, the distance between the bottom of the drill pipe support opening and the other long side of the raft is 60 mm to 120 mm. It can make the tail end of the drill pipe about 50mm from the ground, which is enough for the screw joint operation.
作为本发明的优选方案，所述手柄的直径为25mm，长度为1.2m～1.8m。操作人员握持比较方便，不用弯腰操作，且可以省力。As a preferred embodiment of the present invention, the handle has a diameter of 25 mm and a length of 1.2 m to 1.8 m. The operator is more convenient to hold, does not need to bend over, and can save labor.
作为本发明的优选方案，所述半圆形开口的半径为90mm～145mm。可以适应三英寸半、四英寸、四英寸半、五英寸和五英寸半的钻杆。As a preferred aspect of the invention, the semicircular opening has a radius of from 90 mm to 145 mm. Can accommodate three-and-a-half, four-inch, four-inch, five-, five-, and five-and-a-half-inch drill pipes.
