    2. A device according to claim 1, characterized in that the working cavities of the hydraulic cylinders of the sensors and the receptacle are filled with plastic.
    3. The device according to PP, 1 and 2, on t-. Likewise, the boom position sensor stem is installed with the ability to interact with the boom through a stop made on the boom.
    The invention relates to a device for preventing a collision between a part of the notch bar and a part of the loading chute of a tunneling machine and can be used in the excavation of mines.
    The aim of the invention is to improve the reliability of the device.
    Fig. 1 shows the projectile machine J in Fig. 2 — cylinder-piston units forming sensors, and a piston forming a receiving device; FIG. hydraulic piston forming receiving unit with distribution valve.
    The notch bar 1 is pivotally connected to the tunneling machine 2 with the possibility of raising and lowering relative to axis 3. The loading chute 4 can be rotated about the horizontal axis 5 and pivotally attached to the tunneling machine 2. With the help of a hydraulic cylinder 6 that is ... point 7 to the notch bar 15 is last rotated about axis 3. In addition, the bar can be rotated sideways relative to the vertical axis 8. The hydraulic cylinder 9, which is connected at point 10 to the loading tray 4, serves to turn the ice in the vertical direction.
    The notch bar is equipped with a sensor 11 having a hydraulic cylinder, and the loading tray is equipped with a sensor 12 also having a hydraulic cylinder (FIG. 2).
    Sensor 1 includes a hydraulic 11; cylinder with cylinder 13 and piston 14. Cylinder 13 is mounted on part 15, co213989
    4. The device according to claims 1 to 3, characterized in that the switching body is made in the form of a spool with distribution grooves that connect the hydraulic cannon; 1, providing lowering the boom and raising the tray, with a drain line.

    united with the driving machine. Bar 1 has an abutment 16, with which the piston rod 17 of the piston 14 interacts. With the spring 18 the piston 14 is pressed into
    the direction to the stop 16. The movement of the piston 14 is limited so that the rod 17 interacts with the stop: 16 only in the lower part of the turning trajectory in the vertical: plane. The hydraulic cylinder 9, which at the point 10 is pivotally attached to the loading chute 4, is mounted on the tunneling machine. Cylinder 19 cylinder hydraulic sensor 12
    mounted on cylinder 9 and, therefore, on the tunneling machine itself. The rod 20 of the hydraulic cylinder 12 is connected to the pro-spin 21 on the rod 22 of the hydraulic cylinder 9 connected to the loading chute by means of a part 23 welded to the lug 21. Therefore, no force is required here.
    When the boom is lowered, the cylinder cavity 24 is reduced and the working medium, such as oil, is forced out via pipelines 25 and 26 into the working cavity 27 of the hydraulic cylinder 28 forming the receiving device. If the loading chute rises, the working sump 29 of the piston 21 of the hydraulic cylinder 12, which is a loading tray-ka sensor, is removed. The hydraulic working medium is then displaced through pipelines 30 and 26 into the working cavity 27 of the hydraulic cylinder forming the receiving device.
    five . .
    Thus, when the boom is lowered and the tray 4 is raised. The working medium is displaced into the cavity 27 and the piston 31 of the hydraulic cylinder 28 forming the receiving device is pressed to the right by the sum of the volumes of working medium. Turning the piston 31 to the right is determined both depending on the lifting of the chute and depending on the lowering of the boom, and if the sum of the volumes of working medium from the hydrodilins of the sensors 11 and 12 reaches the value at which the boom and the chute approach each other. degree, the piston 31 stops lowering the boom and raising the chute.
    The piston 31 is removed by the spring 32 to the left. The working cavity 27 of this piston enters through pipe 33 33. A spool 34 is connected to the piston 31, which is moved in the spool mirror 35. Distribution 13989
    An aperture 36 is connected to a mainline, which provides the lowering of the boom 1. A distribution opening 37 is connected to
    5 by a hydraulic line, which ensures the lifting of tray 4. The distribution opening 38 is connected to a drain line. The spool 34 has distribution grooves 39 and 40, which are connected via radial channels 41 and 42 to the central channel 43 of spool 34. When the grooves 39 and 40 are aligned with the openings 36 and 37, these openings are connected channels 41 and 42 and a central channel 43 with an opening 38. In this case, the main hydraulic lines that lower the boom and raise the tray, through the opening 38 connect 20 to the drain line and at the same time lift the tray and lower the boom, thereby eliminating the risk of collision.
