Abstract

The invention relates to the welding industry, namely to devices for assembling and disassembling large-sized units such as downhole motors. The aim of the invention is to increase productivity, reliability and safety in operation by supplying the device with additional electromagnetic and electromechanical drives, an additional gripping unit, force and displacement sensors, and a control panel. This ensures that different drives are automatically switched on depending on the pressing out forces. The downhole motor 22 is placed on a fixed yoke (T) I. Then the power cylinders (SC) 3 and 8 gripping units are engaged. SC 6, resting its rods 7 in the mobile T 2, mixed T 2 together with the shaft clamped in it. After moving the last from a place the effort falls. Information about this comes to the console and at the command of SC 6 returns to its original position. Further extrusion is carried out by switching on the electromechanical actuator II. In the event that the pressing force does not fall, the chain drive moves the node to be processed in the opposite direction by the stroke value of SC 6. If it is impossible to press out, the electromagnetic drive 10 is activated in this order, which abruptly moves the motor shaft relative to its body. The assembly of the assembly described is carried out by means of an electromechanical drive. 3 h. n. f-ly, 3 ill. S (L 3 9 12 jg fue J co w eed sd nu co

Cylinders 3 of the gripping unit mounted on the mobile cross member and strong forces act only at the initial stage, at the moment of repressing and when the maximum forces are reached when the shaft is moving, the forces fall sharply, as a result of which the pressure of the rods 7 of the power cylinders 6 at some time interval at the ends of the mobile cross member 2 weakens sharply, the sensors 17 are triggered, the signal returns to the control panel 14. The hydraulic station 15 arrives

the command to turn off the power cylinders 6, the rods 7 of which are returned

in the initial position, the electromechanical actuator 11 receives the command to activate it.

The electromechanical actuator 11 has a system for smoothly varying the rotational speed depending on the load arising during disassembly, a reversing system and an electrical protection system. Speed

the movements of the movable crosspiece 2 and, accordingly, the speed of repressing the shaft of the downhole motor 22 change smoothly and at different speeds at some intervals of time. The less load - when disassembling the downhole motor 22, the higher the rate of repressing, and vice versa.

The electromechanical actuator 11, through the chain transmission 13, begins to move the movable yoke 2 together with the shaft of the downhole motor 22 to the right, while the shaft of the downhole motor 22 moves along the guide rollers 12. The moving yoke 2 moves in its movement to the sensor 20, which, , sends a signal to the control panel 14, commands from it are received to turn off the power cylinders of the main gripping unit and the power cylinders 8 of the first stage of the additional gripping unit.

The shaft and housing of the downhole motor 22 are loosened, after which the housing and shaft of the after-running engine 22 are removed from the hydraulic device, the sensor 21 after removing the case is activated and the command from the control panel 14 forces the electromechanical drive 11 through the second stage chain 19 control panel 14. The movable yoke 2 comes to its initial position against the stop with the rods of 7 power cylinders. After that, the electromechanical actuator 11 is turned off and the power cylinders 6 are turned on, the shaker 7 moves and moves the mobile yoke 2 to the right. Further repressing of the downhole motor 22 takes place in a similar

The work of the subsequent steps of the magazine grippers 8 is carried out with subsequent possible jamming of the shaft of the downhole motor 22.

In the case of an extreme and unpredictable situation, associated with the impossibility of repressing the downhole motor 22, for example, in the event of a failure of the power cylinders 6, it is necessary to disconnect the shaft from the bottom of the downhole motor 22. In this case, the board (not shown) of the control panel 14, the inscription lights up, saying that repressing is impossible. Then the operator servicing the hydraulic device presses the “On” button. email magnets, and the power supply 13 move the movable yoke 2 25 enters the electromagnets 10, so to the left against the stop with the power 7 brushes as the electromagnets of the same hydraulic cylinders 6 into the initial position, polarity, repulsive forces, arising their operation are transmitted to the sub-mechanical drive 11 and the hydraulic-vise traverse 2, which, moving

to the right, the shaft shuns for a short period of time, after which the electromagnets are turned off and the shaft 15 is removed from the body of the downhole motor 22 by the station 15. The message “Ready to press out: indicating the end of the pressout” lights up on the control panel, after which the following engine, and the process proceeds again in a similar order.
