    1497569 Automatic control of tension CONTINENTAL OIL Co 11 June 1975 [4 Nov 1974] 25070/75 Heading G3R Tension in a pipe-line is kept constant by automatically controlling the position of a "turn vehicle" 30, round which a 180 degrees loop is formed, in response to an electrical signal indicative of the pipe-line tension exceeding prescribed limits. The limits may be selected according to whether the end of the line is advancing, stationary, or withdrawing. The "vehicle" may be self powered but as shown it is moved by a winch 64 and the tension is measured by a transducer responsive to the pressure in an hydraulic piston and cylinder 68 connected in the winch cable. Similar transducers may be positioned at bends as at 60 to give an alarm and immobilize the control if tension bÞcomes excessive. The complete system comprises an hydraulic slurry transport pipe 26 and its supply 27, with pneumatic and electrical control lines 48, used in a mine with a work face 18. The pipe-line is supported along its length by wheeled, articulated "links" (42), Fig. 2 (not shown). The "turn vehicle" Fig. 4 (not shown) has a ramp to lift the wheels off the ground, the links being supported by, and sliding on, the inclined surface. The supports and the "turn vehicle" are described in Specifications 1428567 and 1497568 respectively.

    The invention relates to the mining industry, namely to devices for monitoring the flow of flexible pipelines of hydrotransport systems,
    A known control system for a mining machine, comprising a winch with a reversing electric motor, a regulator, a cable tension sensor, by which the winch is connected to a mobile mining machine TI.
    However, this system is designed to maintain the speed of the mining machine and prevent cable breaks and cannot be used in this form to control the mining machine with the hydraulic transport of the mineral, to ensure the speed of its movement and prevent breaks in the hydraulic pipelines.
    Closest to the invention is a mining machine control system with hydro mineral transport, including a self-propelled pump unit, the pipelines of which are mounted on wheeled carts, and a pressure pump 2.
    However, in the known system, the automatic movement of the pipelines is not provided and their tension is not controlled. This reduces the performance of the mining machine and the reliability of pipelines.
    The purpose of the invention is to increase the productivity of the mining machine and the reliability of the pipelines.
    The goal is achieved by the fact that the system is equipped with movable and uncontrolled turning nodes, tensioning cables of turning units and tensioners of the cables, a winch with a reversing electric motor, anchors and a tension controller, to which output the tension sensors are connected, and the torus is connected to the reversible electric motor of the winch, with the fixed noBOpoTHbte nodes being attached by means of cables through tension sensors to the corresponding anchors, and the movable swivel unit is suspended by means of a cable Through the nat sensor to winch.
    FIG. 1 shows a general scheme of the entire system; in fig. 2 - diagram of the electrical part of the system.
    The coal mined by the mining machine 1 (Fig. 1) goes to the self-propelled pumping unit 2, which is connected by pipes 3 and 4 to the pressure pump 5 and the connecting unit 6, respectively. Pipeline 3 receives clarified water, and pipe 4 - the slurry. The pipelines are mounted on wheeled carts 7 passing through fixed swivel assemblies 8 (only one such unit is shown in Fig. 1, but there may be several of them) and a movable rotary unit 9.
    Each individual stationary swivel unit 8 is attached by means of a tension cable 10 through a tension sensor 11 to an anchor 12.
    5 - The movable swivel unit 9 is suspended by means of a cable 13 via a tension sensor 1t to the winch 15.
    The control unit 16 for controlling the self-drive unit of the pump unit's hub, the tension sensors 11, through the junction box 17, is connected to the control unit 18, to which the tension sensor 14 is also connected.
    In the control unit 18 (Fig. 2), a regulator 19 is placed to the inputs of which the outputs of the tension sensors 11 and 14 are connected. A reversible electric motor 20 of the winch 15 is connected to the output of the regulator 19. The tension sensors 11 are connected to an emergency stop relay 21 connected to the regulator 19 and the reversible electric motor 20.
    The control panel 16 is connected to the switch 22 of the tasks connected to the selective switch 23 of the settings, and its turn connected to the controller 19.
    The system works as follows. As the machine 1 moves up (fig. 1),
    self-propelled pumping unit 2. By lowering the movable swivel unit 9, timely delivery of pipelines 3-4, moving together with the pumping unit 7, is ensured.
     The lowering (and in preparation for the next cycle of the shifting - lifting) of the movable swivel unit 9 is carried out with the help of a winch 15.
    To prevent breaks in the pipelines 3-4 and the links of the wheel bodies of the ek 7 during their movement on the movable 9 and the stationary swivel nodes 8, the tension on the respective cables 10 and 13 is controlled.
    To do this, on the operator control panel 16, one of the operation modes is selected: manual or automatic control “With manual control. 31, the whole complex of mechanisms is either turned off or turned on to lift the movable swivel unit 9, if necessary, move back from the mountain tunnel 1. The remote control 16 is manually controlled using the task selector (not shown in Fig. 2) can be remotely changed the settings of the regulator 19. With automatic control (Fig. 2), the signals from the sensors 11 and tension I go to the control unit 18 to the regulator 19, controlling the reversing motor 20 of the winch 15 When increasing the tension of one of the cables 10 or 13 (Fig 1) beyond a given About the value of the signals of the above-mentioned sensors through the regulator turns on the electric motor 20 of the winch 15 (Fig. 2), which ensures the lowering of the movable swivel 1 664 of the node 9 to reduce the tension of these cables below the values of the regulator 19. Settings. the whole complex of mechanisms is shut off with the help of the emergency stop relay 21 until the reasons for this rope tension are eliminated. The setting of the settings of the regulator 19 in the control unit 18 is carried out by the switch 22 of the tasks through the selective switch 23 of the settings. The use of the system will improve the accuracy and reliability of control by providing the possibility of full automatic control over the entire length of the pipe-carrying truck system, thereby reducing the number of personnel serviced, and increase the safety of mining operations.
