Description

one

The invention relates to equipment for the construction of general purpose pipelines.

The known actuators for cleaning and priming pipelines, including an internal combustion engine mounted on a common frame, a clutch coupling, a transmission and a lever for regulating the supply of priming material, do not ensure uniform priming of pipeline sections. In addition, in the process of work there are large losses of priming material.

The purpose of the invention is the elimination of non-primed sections of the pipeline without loss of the priming material.

For this purpose, the drive of the pipe cleaning and priming unit is made with an additional electric motor with a gearbox, one end of the output shaft of which is kinematically connected to the clutch lever and the lever lever of the priming material, and the other end of the output shaft of the gearbox is connected to a board mounted for movement relative to the shaft , on which is also installed an electric motor that interacts through a screw gear with a lever of the nozzles of the internal combustion engine.

FIG. 1 shows a device for

cleaning and priming of pipelines, general view; in fig. 2 shows a kinematic diagram of the device drive. The drive of the device includes an internal combustion engine 2 mounted on a common frame 1, a clutch (not shown in the drawing), a transmission 3, cleaning bodies 4, and a lever 5 for regulating the feed of priming material. Engine control

2 is carried out by the lever 6 of the nozzles of this engine and the lever 7 of the clutch.

On the frame is mounted an electric motor 8, articulated with a gearbox 9. At one end

the output shaft 10 of the gearbox with the possibility of axial movement relative to this shaft is installed a board 11 with an additional electric motor 12 connected by a screw gear 13 with a lever 6. A spring 14 and

stops 15 and 16 are designed to limit the movement of the board I. The final switches 17, 18 and 19, included in the motor control circuit 8, limit the movement of the output shaft 10 or, which is one

and the same, the angle of rotation of the levers 5, 6 and 7, the end switches 20 and 21 of the rotation of the lever 6, and the stop 22 - the rotation of the lever 7. The drive works as follows. At the beginning of its operation, the output shaft 10 of the gearbox 9 is in a position in which the clutch is disengaged, the priming material is not fed, and the fuel supply to the engine 2 is limited. When the motor 8 is turned on, the output shaft 10 of the gearbox 9 moves together 5 with the board 11 towards the limit switch 18. At the same time, the lever 6 turns, increasing the fuel supply to the injectors of the engine 2, the lever 7 turns, smoothly engaging the clutch, and turning lever 5, including a primer supply valve. When the output shaft 10 reaches the position corresponding to the limit switch 18, the motor 8 is turned off, 15 the lever 7 reaches the stop 22, and the board 11 goes to the stop 15, the clutch is turned on, the fuel is supplied to the nozzles in the amount necessary to start the machine, and the supply of priming material is limited to 20 average. During operation of the drive, it is possible to re-enable the electric motor 8 to increase to a maximum value or reduce the supply of priming material to an average value, while the lever 7 pressed to the stop 22 does not turn, and the board II is pressed to the stop 15 by the spring 14, does not move. If it is necessary to change the supply of top 30; | willow to the injectors of the internal combustion engine, an additional electric motor 12 is turned on, which rotates the lever 6 by means of a screw 13. Object of the Invention A drive for cleaning and priming a pipeline, including an internal combustion engine mounted on a common frame, a clutch, a transmission and p A control lever for supplying priming material, characterized in that, in order to exclude non-primed sections of the pipeline, it is made with an additional electric motor with gearbox, one end of the output shaft of which is kinematically connected with the clutch lever and the lever of the crane for supplying the priming material and the other end of the output shaft the gearbox is connected to a plgata installed with the possibility of movement relative to the shaft, on which a motor is also installed, which interacts with a screw edachi with lever rails injectors of internal combustion engine.
