[0045] 参见图1至图15,本发明的工作原理是:首先将钻杆插入本发明的拧管机,并使钻杆连接头以下的部位处于夹持机构2的卡瓦25形成的夹持腔254内,连接头30以上的部位处于拧卸机构I芯管14及以上的位置;再用搬叉16的叉口161部分夹持上段钻杆20,并使卡柄162架设在两卡设在所述拨环15的两挡柱151之间。 [0045] Referring to FIG. 1 to FIG. 15, the working principle of the invention is: first threaded drill pipe is inserted into the machine of the present invention, and the drill pipe connector clip clamping mechanism is in a portion 25 formed in the slip 2 the holding chamber 254, connected to head portion 30 or 14 and at a position above the core tube I breakout mechanism; then conveyed cross section portion 161 on the fork 16 holding the drill rod 20, the stem 162 and the card erected two card dial ring disposed between said two gears of column 15,115. 启动环形油缸21,使夹紧活塞212向上移动,斜面2124及滚子排24对卡瓦25施以向内的作用力,使卡瓦25向内移动,并且卡瓦25在自重的作用下沉,大大地加大了夹持力,以抱死钻杆,处于如图7所示的状态。 Start the annular cylinder 21, the clamp piston 212 moves upward, the inclined surface 2124 and the discharge roller 24 to impose a force on the slips 25 inwardly, so that the slips 25 move inwardly, and the slips 25 in its own weight sink greatly increase the clamping force to the locking rod, in the state shown in FIG. 7. (如果要松开卡瓦25,则反向启动环形油缸21,使夹紧活塞212向下移动,斜面2124及滚子排24对卡瓦25向内的作用力减小直到消失,在第一压缩弹簧22产生向上的弹力以抵消卡瓦25因自身的重力,使卡瓦25不会下沉,从而保持松开钻杆的状态,即如图8所示的状态。)启动拧卸机构I的电机11,以带动大齿轮13旋转,由于刚开始拧卸,钻杆连接头的阻力很大,电机11给大齿轮13的力不足以使大齿轮13顺利旋转,此时再启动冲扣机构3的直线油缸31,直线油缸31的直线活塞311前进并带动杠杆32绕环形旋转部322的中心也即大齿轮13的中心旋转。 (To release the slips 25, the annular cylinder 21 is started in reverse, so that the clamp piston 212 moves downward, the inclined surface 2124 and the discharge roller 24 to reduce the force of the slips 25 inwardly until it disappears, the first the compression spring 22 generates elastic force to counteract the upward slip 25 due to their own gravity, so that the slips 25 will not sink, thereby maintaining the state of disengaging the drill rod, i.e., the state shown in FIG. 8.) start I breakout mechanism motor 11 to drive the large gear 13 rotates, since the beginning of breakout, great resistance to the drill pipe connector, to force the motor 11 is insufficient to cause the large gear 13 gear 13 rotate smoothly, then re-start mechanism Exploded Line Line 3 of the cylinder 31, the linear cylinder 31 and piston 311 advances drive lever 32 about the center of the annular portion 322 of the rotation center of the large gear 13 that is rotating.

[0046] 现以第一种弹性棘爪装置33为例说明冲扣机构3的工作原理:杠杆32旋转一定角度时,在第二压缩弹簧332的作用下,所述棘爪331会插入环形旋转部322的其中一棘孔3225,此时杠杆32并与大齿轮13卡紧,直线活塞311的冲击力并可传递给大齿轮13,使大齿轮13获得一瞬时冲击力。 [0046] Now a first resilient detent means in an example 33 Exploded mechanism works 3: when the lever 32 is rotated a certain angle, in the second compression spring 332, the pawl 331 inserted endless rotary wherein a portion of the ratchet hole 3,225,322, when the lever 32 and the large gear 13 with the gripping, linear impact force transmitted to the piston 311 and the large gear 13, the large gear 13 to give a momentary impact force. 之后直线活塞311后退,由于棘爪331具有一个滑行面3312,在直线活塞311后退时,棘爪331可以顺利退出所述棘孔3225,这样直线油缸31传递给大齿轮13的力只有动力而非阻力。 After the linear piston 311 retracted, since the pawl 331 has a sliding surface 3312, when the linear piston 311 retracted, the pawl 331 may smoothly exit the ratchet hole 3225, so that a straight line the cylinder 31 is transmitted to the large gear 13 of the force not only power resistance. 如此多次往复之后,在电机11和直线油缸31的共同作用下,使拧卸机构I有足够的力量将上段钻杆20从下段钻杆40旋开。 After so many times back and forth, under the action of the linear motor 11 and the cylinder 31 of the breakout means I have sufficient force to the drill pipe 20 from the lower opening 40 of drill pipe rotation. 另外,若是要安装钻杆时,即将上段钻杆20旋在下段钻杆40上并拧紧,只需将棘爪331的滑行面3312的朝向对调即可,此时可通过所述拨环15的调向孔153用螺丝刀等工具将所述调向压盖3331上的直槽3334旋转180度后,由于调向压盖3331的两卡柱3335与棘爪331的两开口槽3314对应扣紧,从而使棘爪331也旋转了180度,所述棘爪331的滑行面3312的高端33121及低端33122的朝向即发生对调,并使第一螺孔3333与其中一第二螺孔154对准后通过紧固螺钉3332锁紧。 In addition, if the drill pipe to be installed, i.e. the lower the drill pipe 20 screwed on the drill pipe 40 and tightened simply sliding surface 331 toward pawl 3312 can be reversed, this time by the dial ring 15 after the transfer to the wells 153 with a screwdriver to adjust the rotation of 180 degrees to the straight grooves 3334 on the lid 3331, due to the corresponding two adjustment gland opening groove 3331 3335 two locking studs fastening pawl 331 3314, so that the pawl 331 is also rotated by 180 degrees, the sliding surface 3312 of the pawl end 331 of the lower end 33122 and 33121 toward i.e. swap occurs, and wherein a first screw hole 3333 and the second screw hole 154 is aligned 3332 by locking the fastening screw. 这样直线油缸31传递给大齿轮13的力方向相反,使抒管机对上段钻杆20施以拧紧的力。 Such straight cylinder 31 is transmitted to the force in the direction opposite to the large gear 13, so that the machine to express the drill pipe 20 is applied tightening force.

[0047] 如果是第二弹性棘爪装置33,其冲扣机构3的工作原理:当直线油缸31的直线活塞311前进时,带动杠杆32绕环形旋转部322的中心也即大齿轮13的中心旋转,旋转一定角度时,在第二压缩弹簧332的作用下,所述棘爪331会插入大齿轮13的其中一棘孔132,此时杠杆32并与大齿轮13卡紧,直线活塞311的冲击力并可传递给大齿轮13,使大齿轮13获得一瞬时冲击力。 Central cylinder 31 when the linear straight forward piston 311, i.e. the lever 32 to drive the large gear portion 322 about a central rotating ring 13: [0047] If the second resilient detent means 33, which works mechanism 3 Exploded rotation, the rotation angle, in the second compression spring 332, the pawl 331 is inserted in one of the large gear 13 of the ratchet hole 132, when the lever 32 and the large gear 13 with the gripping, the piston 311 is linearly and the impact force is transmitted to the large gear 13, the large gear 13 to give a momentary impact force. 之后直线活塞311后退,由于棘爪331具有一个倾斜设置的滑行面3312,在直线活塞311后退时,棘爪33可以顺利退出所述棘孔132,这样直线油缸31传递给大齿轮13的力只有动力而非阻力。 After the linear piston 311 retracted, since the pawl 331 has an inclined sliding surface 3312, when the linear piston 311 retracted, the pawl 33 may smoothly exit the ratchet hole 132, so that the linear cylinder 31 is transmitted to the gear 13 only force power rather than resistance. 如此多次往复之后,在电机11和直线油缸31的共同作用下,使拧卸机构I有足够的力量将上段钻杆20从下段钻杆40旋开。 After so many times back and forth, under the action of the linear motor 11 and the cylinder 31 of the breakout means I have sufficient force to the drill pipe 20 from the lower opening 40 of drill pipe rotation. 但由于棘爪331是固定在杠杆32上,杠杆32又设在大齿轮的底部,因此没有条件设置棘爪调向机构,因此该拧管机只能用于拆卸钻杆,而不能拧紧钻杆。 However, since the pawl 331 is secured to the lever 32, the lever 32 and the large gear is provided at the bottom, there is no condition setting ratchet steering mechanism, so that the machine can only be screwed for removing drill pipe, and drill pipe can not be tightened .

[0048] 综上所述,本发明的拧管机包括拧卸机构、一夹持机构以及一冲扣机构,拧卸机构采用齿轮传动,带动拨环和搬叉卡紧上段钻杆;夹持机构设置有环形油缸、滚子排和卡瓦的相配合的结构,达到自重夹持和液压夹持相结合,夹持力大且可靠,还能降低能耗;冲扣机构的设置可在大齿轮力量不够的情况下,传输一个瞬时的冲击力给大齿轮,以协助大齿轮顺利拧卸,本发明的拧管机结构简单合理,夹持力大,且占地面积小,能耗小,是一理想立轴式钻机的自动拧管机。 [0048] In summary, the present invention is machine screwed pipe breakout means comprises a clamping mechanism and a punch lock mechanism, breakout mechanism gear wheel, driven by said dial ring and the clamping fork on the transport of drill pipe; nip mechanism provided with an annular cylinder, and cooperating structure of the discharge roller slips, achieve weight and hydraulic clamps holding the combination, the clamping force and reliably, but also to reduce energy consumption; clasp means may be provided in the punch large lower gear case power is not enough, an instantaneous impact force transmitted to the large gear, the large gear to assist in a smooth breakout, a simple twist of the machine structure of the invention is reasonably large clamping force, and small footprint, low power consumption, over a vertical shaft tube rig automatic screw machine.
