Abstract
The utility model discloses a double-drum power winch, which has an input shaft that is connected with a bidirectional clutch. The bidirectional clutch is connected with two speed changers on both sides of the bidirectional clutch, and the two speed changers are respectively connected with a drum arranged on a rack. The utility model has reasonable structure, high safety, labor saving, easy operation, and easy control, and can be directly and conveniently installed on a drill floor close to a well head, operation control is far away from the double-drum power winch, force moment and speed can both be controlled, and the utility model is not only labour-saving but also safe.
Description
Technical field:
The utility model relates to a kind of oilfield and bores in (repairing) well operations, the drilling tool tubing string is gone up the device of shackle and spinner operation.
Background technology:
The tradition oilfield bores in (repairing) well operations, the drilling tool tubing string is gone up shackle and spinner adopt that mechanical cat head is used as power on the rig main winch, be wrapped in traction Type B tongs on the cylinder of cat shaft with steel rope or coir rope or carry out last shackle and spinner operation drilling tool as spinning rope, because mechanical cat head is away from center of turntable (drilling tool center), and output torque is big, the rotating speed height needs artificial control its moment size and rotating speed speed.Because impact moment is big during the shackle of operation drilling tool tubing string, and rope (steel rope and coir rope) is broken, and causes the life accident on the rig floor face.And mechanical cat head operation labor intensity is big, so from security consideration, modern drilling operation is all cancelled mechanical cat head.
Summary of the invention:
The purpose of this utility model is to provide a kind of rational in infrastructure, safe, laborsaving, manageable pair of reel power winch.
Technical solution of the present utility model is:
A kind of pair of reel power winch is characterized in that: input shaft is arranged, and input shaft is connected with bidirectional clutch, and bidirectional clutch is connected with two change-speed boxs of both sides, and two change-speed boxs are connected with a reel that is contained on the support respectively.
Bidirectional clutch is mechanical type or fluid pressure type.Bidirectional clutch is connected with two change-speed boxs of both sides by coupler.
The utility model is rational in infrastructure, and is safe, laborsaving, easy to operate, easy to control, can direct convenience be installed on the nearer rig floor of well head, and operation control is away from this device, and moment and speed-controllable system, not only laborsaving but also safety.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing is the configuration diagram of an embodiment of the utility model.
The specific embodiment:
A kind of pair of reel power winch has input shaft 1, and input shaft 1 is connected with bidirectional clutch 2, and bidirectional clutch 2 is connected with two change-speed boxs 3,4 of both sides by coupler 5,9, two change-speed boxs 3,4 respectively be contained in support 6 on reel 7,8 be connected.Bidirectional clutch is mechanical type or fluid pressure type.Two reels 7,8 be arranged as coaxial type, promptly be installed on the transmission shaft, but also twin axle is installed, and promptly is installed on respectively on two transmission shafts.Bidirectional clutch, two change-speed boxs all are installed on complete machine inside, power-transfer clutch interlocking, more compact structure.
During the utility model work, support 6 is to be used to support used unit and installation, and power reaches bidirectional clutch 2 from input shaft 1, when bidirectional clutch is hung fashionable (promptly throwing off) left to the right, power is transmitted left through coupler 5 to change-speed box 3 by bidirectional clutch 2, is passed to reel 7 outputs again.The moment of torsion of reel 7 outputs is big, and speed is low, is used for the shackle operation to the drilling tool tubing string.Hang fashionable (promptly throwing off) to the right left when bidirectional clutch 2, power is transmitted to the right by bidirectional clutch 2, to change-speed box 4, is passed to reel 8 outputs via coupler 9 again.The moment of torsion of reel 8 outputs is little, and the speed height is used for going up of drilling tool tubing string detained and the spinner operation as spinning rope.
Claims (3)
1, a kind of pair of reel power winch is characterized in that: input shaft is arranged, and input shaft is connected with bidirectional clutch, and bidirectional clutch is connected with two change-speed boxs of both sides, and two change-speed boxs are connected with a reel that is contained on the support respectively.
2, according to claim 1 pair of reel power winch is characterized in that: bidirectional clutch is mechanical type or fluid pressure type.
