The invention discloses a tube well tube lifting device which comprises a frame body. The frame body comprises a bottom triangular frame, a top triangular frame and supporting rods, the upper portion of one supporting rod is provided with a limiting rod, the lower portion of one supporting rod is provided with a driving roller, and the upper portions and the lower portions of the other two supporting rods are each provided with a limiting rod. The limiting rods can be horizontally moved and locked, limiting wheels are arranged at the inward ends of the limiting rods, a motor is arranged on the bottom triangular frame, and the motor drives a driving roller to rotate forwards and backwards through a transmission mechanism. During work, the bottom triangular frame is arranged at a wellhead of a tube well, a tube penetrates through the top triangular frame and the bottom triangular frame, the three limiting rods at the upper layer limit the upper point of the tube from three directions, the two limiting rods at the lower layer and the driving roller limit the lower point of the tube from three directions, the limiting wheel is in rolling fit with the outer wall of the tube, and the motor drives the tube to ascend and descend through the driving roller. The device avoids the deformation of the tube, is simple and safe to operate and is high in efficiency, can ensure the coherence of tube operation, and is convenient to manufacture, mount and transfer.
本发明公开了一种管井管材升降装置,包括架体,架体包括底部三角框、顶部三角框、支撑杆,一个支撑杆的上部设有限位杆、下部设有驱动辊,另两个支撑杆的上下部各设有一个限位杆,限位杆均可水平移动和锁定的安装且朝内的一端均设有限位轮,底部三角框上设有电机,电机通过传动机构带动驱动辊正反转;工作时,底部三角框设在管井井口处,管材穿过顶部三角框和底部三角框,上层三个限位杆从三个方向将管材上位点限位,下层两个限位杆和驱动辊从三个方向将管材下位点限位,限位轮与管材外壁滚动贴合,电机通过驱动辊带动管材升降。该装置避免了管材变形,操作简单、安全、效率高,能保证管材作业的连贯,方便制作、安装和转移。
