    U., i; j is robust pouring, and the number of jaws 9 installed on the chip is determined; fastened levers 10 and having the ability;) sdvngatsy or closer to the radial direction by mechanical or hydraulic means.
    The entire installation is symmetrical with respect to the vertical plane B. In FIG. Fig. 1 also shows a schematic of a chuple pipe with a flare: KO7x pa extracted from mold 2 and is supported on retractable supports // before it is sent to another position for further processing.
    The bed 3, in its upper part and along the entire length, has a groove 12 for receiving sand waste from STbl.1. 1 sockets, which break down during extraction. This chute has a flat bottom and on each side has a flat horizontal flange 13, to which the guides 4 are fastened (Fig. 3). On the bed 3, in its lower part, as well as on the capped side, there is a flat horizontal flange 14, which ends beyond the plane of symmetry than the corresponding flange 13, and continues with the vertical wall 15. Between the walls 15 and the shoulders of the groove there is free space and The bed 3 has two side open hoppers 16 with a rectangular cross section.
    The carriage 5 with each old one has an edge 17, on which the vertical foot 18 is fixed, is located on the same line with the wall 19, a little is not income to it. At the end, the tab 18 has a finger 20, which is parallel to the plane B, and is located in the bunker / 6 under the corresponding shoulder 13.
    The carriage 5 also has in its rear part a landing place or a collar 21 for a pulley 22 with a vertical axis.
    The movement of the carriage 5 along the guides 4 is provided with a winch and three cables - an upper cable 23 and two lower cables 24 and 25.
    The winch drum i26 has a cylindrical 4x) (omu-c mountains (izant.al) al axis), tert.divary axis bb, and its upper arm is in the plane of the pulley 22. The cable 23 (flexible pulling member), which is intended for retraction the carriage 5 forms a loop that covers half of the entire circumference of the balance pulley 22, and both of its: End are attached in series on the same forming drum 26.
    Each cable 24 and 25, designed to allow the carriage 5 to move forward, has an end 27 fixed to the end of the drum 26. From here it passes down to the first guide pulley 28, iaTOM horizontally forward in the lower part of the hopper 16 to the second guide pulley 29 located opposite the pepe ;; i: ei4j game |) au chitel of move 7, and after June; h) |) in the 1st horizon of HanpaLs.ifnpi back to the top of the bunker / 6,; ..рэ (ИИСЯ on the finger of the 2G carriage -: 5. Each e-cable 24 and 25 is located in a vertical IL / TOC x / 11 D parallel to the plane B.
    Pulleys 29 still roll the vehicle ysiopaMii 30, while the stops 31 of the pulleys 28 are adjustable.
    0 parallel to the axis bb through the itah of the device with the threaded rod 32. Thus, the tension of the cables 24 and 25 can be adjusted. Alternatively, this solution would be subject to
    5 tension devices, rigidly connected. 1 with each patch of 1 carriage 5.
    14, regardless of the position of the carriage 5, there always remains some part of the cables 23, 24 and 25 wound on the reel 26. Both branches of the cable 23 are wound in the same direction, which is the opposite direction to the winding of the ends of the cables 24 and 25.
    The proposed machine is running CL5. in a sensible way.
    At least: at one end of the drum 26 there is a hydraulic motor located at a single, non-disposable engagement with this 1H1 drum.
    0 or work machine 33, having two speeds. Each working machine 33 can optionally operate, either providing a large speed of rotation, but a high torque, or providing a speed twice as high as the previous one and two times a lower torque. In order to make this choice of speeds and torques, each lender has a coaxially mounted key.
    0 pan or valve 34 with two active positions in each direction. The distributor 34 is able to distribute the working fluid (oil or water) by means of the corresponding channels.
    5 supplied by a pressure vessel to a common pipeline 35 running from the common pump 36. The drive system 37 also completes the descent or return channel IB of the liquid exiting each engine and its distributor to the net.
    The dust cover 38, adjacent to the bed 5, closes the winch and has narrow openings for the passage of cables.

    At the beginning of the extraction process, the carriage 5 is at the end of the reverse stroke, for example, in the stop position at the backstop 7. The ingot 2 is at the end of its path adjacent to the horizontal guides 4.
    During the rotation of the winch drum 26 towards the mold 2, the cables 24 and 25 exert a thrust force on the legs 18 of the carriage 5 and are wound on the drum 26.

    Claims (3)

    f At the same time, the double cable 23 is washed out at the same speed from this drum. This rotation of the drum 26 is effected, for example, until the carriage 5 is latolnetted; on the upper limit stop 7 it is thus actuated in this way by a control switch. The beam 8 and the jaws 9 are then inside the pipe. The lips 9 are diluted and the pipe is hooked on the inside. At this point, considerable effort must be applied to separate the pipe from the chill mold and begin to move it in the direction of the chill and remove it from the chill mold. The motor provides its maximum torque and the drum 26 rotates very slowly away from the mold. The cable 23 exerts on the carriage 5 a large pulling force, which is distributed into two equal forces along its two branches with the help of a tension balance bar 22, which does not rotate. Thus, the pipe is torn off from the chill mold and its mouth comes out of the chill mold. Starting from this moment, it is no longer necessary that the carriage 5 exerts a large pulling force on the pipe. On the contrary, it is desirable that the rest of the extraction operation be carried out as quickly as possible. During this first extraction phase, the carriage 5 has moved a very small distance, for example, less than a meter. The drum 26 now rotates at a relatively high speed, in any case this speed is much higher than the speed corresponding to the separation of the pipe. Both branches of the cable 23 are wound onto the drum 26 at the same time, while the cables 24 and 25 are unwound. The supports // come to the horizontal working position in order to receive: the pipe before sending it. The carriage 5 stops its turn back, i.e. the extraction stroke. By splitting the cable feed system forward, it became possible to protect it simultaneously from above using the shoulders 13 of the chute 12 and laterally using the walls 15 of the bed 3, thus providing this protective casing to this system that is very effective against emptying or falling sand (Fig. 3) bell-shaped rod. The reversing cable 23 is constantly outside the area accessible to the waste of sand, and therefore it is not subject to sand. In addition, the cables 23, 24 and 25 are protected from pop-up dust on them with the help of a casing 38 covering the winch. Therefore, they can remain suitably lubricated. The cable system with a single winch drum is a well balanced system due to symmetry with respect to plane B. Both branches of cable 23 operate under equal tension n, therefore, they do not allow the carriage 5 to deviate from the track. The carriage 5 cannot bend under the action of the pulling force, in particular, due to the fact that the pulley 22 is located in the horizontal plane, in which the extraction axis is located. Claim 1. A machine for extracting centrifugally cast pipes from molds, comprising horizontal guides of the bearing carriage, a chute for collecting sand, mounted between horizontal guides, trays, flexible pull branches moving the carriage back and forth, a drive device consisting of upper a driving mechanism mounted on the back of the carriage, and a lower bearing mechanism mounted on the lower lip of the carriage, a working drum, pulleys, and an engine, characterized in that, in order to accelerate and to improve the extraction of pipes from molds, the upper pulling mechanism is equipped with a balancing pulley mounted behind the carriage, and is made with two symmetric flexible pulling branches relative to the vertical plane of symmetry of the carriage n the envelopes of the balancing pulley, and each separate half of the lower pulling mechanism contains two flexible branches , one-sided K01ShCHI which are fixed on the working drum.
