    (5) DRIVE PIPE STANDARD
    one
    The invention relates to a mechanized tool for assembling and disassembling threaded connections, in particular, drilling, casing and tubing, and can be used during exploration, development and operation of oil fields.
    Pipe wrenches are known that include a housing with a lever, drive rollers housed in the housing, crimping the pipe, an actuator mounted on the lever, kinematically associated with the drive rollers 13 The disadvantage of the known design is that there is no torque control unit transmitted to the tightening threaded compound.
    The closest in technical essence to the present invention is an actuating pipe wrench, comprising a housing with a lever, a head located in the housing and clamping dies connected to one more, a drive mounted on the lever, kinematically connected with a head, a throttle valve mounted before the actuator and the moment sensor 2 interacting with the end of the lever.
    The disadvantage of this key is that during the process of tightening the threaded connection of pipes, the operator must hold the throttle valve handle in the extreme position, corresponding to the full opening of the throttle valve, until the indicating devices have reached the required torque, and then
    by moving the handle partially or completely shut off the throttle valve.

    20 The purpose of the invention is to provide ease of control of a throttle valve, namely, to ensure that the handle is automatically held in the extreme position until the required moment is reached and its subsequent re-operation to close the throttle valve. The goal is achieved in that the key is provided with a mechanism for locking the handle position with a fully open throttle valve, including a handle fixing unit, an automatic handle release unit and an automatic handle release unit disengaging unit. In addition, the handle fixing unit is made in the form of a spike rigidly fixed on the shaft handle, rigidly fixed at its end an eccentric profile cam with a throat, a lead with a tooth, fixed at the other end of the shaft, and a torsion spring interacting with one end a driver and intended to press the cam to the spike of the handle; The assembly of the automatic release of the handle is made in the form of a solenoid, which receives the signal from the torque sensor installed in the housing on the axis of the L-shaped earring, interacting with the rod of the solenoid rigidly connected with the L-shaped pbii-iara shackle, on one shoulder of which there and the locking tooth, which interacts with the tooth of the fixation assembly fixture, and the other arm interacts with the second end of the torsion spring of the same assembly; the knot of disconnection of fixing and automatic release of the handle is made in the form of a shaft, at one end of which a handle is fixed, and the other is a plate-stopper interacting with the stop of the L-shaped lever of the automatic release of the handle. Figure 1 shows a power pipe wrench, general view; figure 2 - section aa in Fig, 1; on fig.Z - section bb in figure 2; in fig. - section bb in fig.Z; Fig. 5 shows the same at the time of the operation of the automatic release of the handle; Fig. 6 is the same, when the knot of disengagement of the fixation knots and automatic release of the handle triggers. The drive pipe wrench includes a housing 1 with a lever 2, a head (not shown) located in the housing, and dies 3 connected to it, an actuator placed on the lever 2, kinematically connected with the head, mounted before operation of a throttle valve 5 with a handle 6, the torque sensor interacting with the end of the lever is not shown). A spike 7 is formed on the handle 6. The lever 2 has a mechanism 8 for blocking the position of the handle b with the throttle valve 5 fully open. The mechanism 8 for blocking includes a fixing unit for the handle 6. an assembly for automatically releasing the handle and an assembly for unlocking fixation units and automatic release the handle. The handle fixing unit is made in the form of a spike 7, a shaft 9 rigidly fixed at one end of the eccentric profile cam 10 with a shed 11, a leash 12 with a tooth 13 rigidly fixed at the other end of the shaft 9, and a torsion spring 1 interacting with one end with a driver 12 and intended to press 1 of the pawl 10 to the spike 7. A knob for automatically releasing the handle in the form of a solenoid 15, receiving the signal from a torque sensor installed on the axis 16 of an L-shaped shaft 17 interacting with a rod of the solenoid 15 rigidly connected with se goy 17 of L-shaped lever 18, one arm of which there is a stop 19 and the locking tooth 20 cooperating with a tooth 13 of a lead fixing unit 12, and the other arm interacts with a second end of the spring and the torsion of the same node. The knot of disengagement of the fixing and automatic release knobs is made in the form of a shaft 21, at one end of which a handle 22 is fixed, and on the other - a stopper plate 23, interacting with the stop 19 of the L-shaped lever 18. The solenoid rod 13 is connected with a link 17 using a cotter pin 2k. The handle b is connected to the throttle valve by means of a 25-axis. The key is held above the well head by means of a suspension 26 connected to a drilling or production tower. The key works as follows. Typically, the drive pipe wrench is rotated by a hydraulic actuator, which is controlled by the throttle valve 5 by means of the handle 6. The operator, standing near the pipe wrench, actuates the valve 5 by means of the handle 6, which is squeezed forward (as viewed from FIG. 1) the dies of the 3 keys rotate clockwise and the pipes are screwed. When the handle 6 is pulled back in the opposite direction, the valve changes the direction of fluid flow to the reverse and the direction of rotation of the dies 3, i.e. the pipes are unscrewed. Between the position of the forward and reverse rotation is the neutral or inoperative position of the handle 6, which is usually shifted to this position. To perform the screwing operation, the drive k is turned on and the handle 6 is pressed forward until the thorn 7 stops against the cam 10. In the process of pressing the handle 8, the thorn 7 rests against the cam 10, and due to a sharp drop in its profile, it is rotated until the spike 7 will not go into the jaw 11 of the cam 10, which is locked by the driver 12. At this moment the tooth 13 of the driver 12 is engaged with the locking tooth of the 20 L-shaped lever 18. When the position of the handle 6 is fixed in this way, the throttle valve 5, the fluid passes in the Water that makes the pipes screw together As the torque increases, it is recorded by means of a sensor connected to the end of lever 2 and transmitted to recording instruments. Upon reaching the torsional moment limit, the signal from the sensor also enters the node of the automatic release of the handle. Under the action of this signal, a solenoid 15, which interacts with an earring 17, which rotates around axis 16, is triggered. Together with serge 17, the L-shaped lever 18 also rotates, and its locking tooth 20 releases tooth 13 of the leash 12, which in turn under The torsion spring 14 rotates counterclockwise (FIG. 5) Together with the driver 12, the shaft 9 and the cam 10 rotate, The cam 10 rotates with its profile surface and pushes the spike 7, and with it rotates the handle 6 to the neutral position or close to him. Simultaneously with the rotation of the handle 6, the throttle valve 5 also moves, connected with it by means of the axis 25 and completely or partially blocking the access of fluid to the hydraulic actuator. Then the operator switches to manual control. In case the operator wants to switch to full manual control, he turns on the knot of disengaging the fixing knots and automatically releasing the handle. To do this, it rotates the handle 22 clockwise (FIG. 6) until it stops. In the process of turning the handle 22, the axis 16 and the plate-stopper 23 turn along with it, which with its end presses the stop 19 of the L-shaped lever 18 and causes it to turn clockwise. When the L-shaped lever 18 is rotated, the shackle 17 also rotates with it, at the same time its locking tooth 20 releases the tooth 13 of the leash 12, the leash 12 rotates with the cam 10, as indicated above. Subsequent squeezing of the handle 6 forward until the thrust stop into the cam 10 and the subsequent rotation until the thrust 7 stops into the cam 10, the locking of the cam 10 does not occur, since, turning together with the cam 10, the tooth 13 of the leash 12 does not engage with the locking the tooth of the 20 L-shaped lever 18, since the lever 18 is at this moment retracted by the plate-stopper 23, which rests against the abutment of the 19 G-bar lever 18, therefore, with the knock-off and automatic release knob off, the operator must all hold the handle weave to the edge it rest position and transfer it to the neutral position, guidance indication Referring E devices. Since the automatic release handle assembly is also disconnected, the shackle 17, together with the L-shaped lever 18, is in the turned (clockwise) and locked position by the stopper plate 23, which is retained. living them, resting against the rest 19 of the L-shaped lever 18, the automatic release of the handle does not work. Claims 1. Drive a pipe wrench, comprising a housing with a lever, placed. In the housing, the head and the clamping dies associated with it, a drive mounted on the lever, kinematically connected 79 to the head, a throttle valve with a handle installed in front of the water and a torque sensor that interacts with the end of the lever, in order to ensure convenience throttle valve control, it is provided with a handle position locking mechanism with the throttle valve fully open, which includes the handle fixing unit, automatic handle release unit and the fixing unit shutdown unit automatic released handle. , 2.
