Manual drawbench
The invention provides a manual drawbench which comprises a support. A transverse rod is arranged on the support and provided with movable slide wheels capable of sliding along the transverse rod. Thebottom of each movable slide wheel is provided with a pulley block. The bottom of each pulley block is connected with a drill stem connector. Each drill stem connector is used for being fixedly connected with a drill stem. The drill stem connectors further include the second drill stem connectors. Each second drill stem connector structurally comprises a torque part fixing element and a tensioning steel wire rope movably installed on the torque part fixing element, wherein the torque part fixing element is of an open frame structure matched with a drill stem torque part of the corresponding drill stem, the inner wall of the torque part fixing element fits part of the drill stem torque part, the outer walls of the two sides of an opening of the torque part fixing element are provided withtensioning grooves and/or tensioning holes, the tensioning steel wire rope penetrates through the tensioning grooves and/or the tensioning holes, and the ends of the tensioning steel wire rope are connected with a lifting hook of the corresponding pulley block. The weight of the whole device can be greatly reduced, and the tube drawing construction can be conveniently performed on a complex-terrain natural slope.
本发明提供一种手动式拔管机，它包括支架，在支架上设有横杆，在横杆上设有可沿横杆滑动的移动滑轮，移动滑轮的底部设有滑轮组，滑轮组的底部与钻杆连接件连接；所述的钻杆连接件用于与钻杆固定连接。所述的钻杆连接件还包括第二钻杆连接件，第二钻杆连接件的结构为：它包括扭矩部固定件和活动安装在扭矩部固定件上的拉紧钢丝绳；扭矩部固定件为与钻杆的钻杆扭矩部相配合的开放框架结构，扭矩部固定件的内壁与钻杆扭矩部的局部贴合，在扭矩部固定件开口两侧的外壁设有拉紧槽和/或拉紧孔，拉紧钢丝绳穿过拉紧槽和/或拉紧孔，拉紧钢丝绳的端头与滑轮组的吊钩连接。本发明能够大幅减轻整个设备的重量，便于在地形复杂的自然边坡进行拔管施工。
