There is also a system for guiding a steel rope on a reel drum according to the Polish patent description no 98 497- This system is equipped with a frame with two guide rollers, steel line counter-rotating on the turnstile drum, positioned parallel to the axis of the rope run, bent at an angle of 110 °, the frame is pivotally connected on the side of the longer arm with clamps fastened to struts, while on the side of the shorter arm, rotatingly with a lever articulated to the turnstile support. Another known device is presented in Polish patent specification No. 104,996. This device has three rollers placed next to each other with a total length corresponding to the active width of the drum. The rolls are pressed along the width of the drum to the wound rope. Two external rollers are attached to two-armed levers, equipped with limit switches, cooperating with cams mounted on two two-armed levers, connected to an internal roller. according to which the pressure roller is composed of three rollers mounted in a holder articulated with an angular lever through a joint. The outermost rollers have the shape of truncated cones and their diameters are larger than the diameter of the central roll having a cylindrical shape, thanks to which the last coil of the rope is constantly pressed against the rope drum, and the horizontal component of this pressure is directed towards the previous coil of the rope on the drum. The ropes on the turnstile drum consist of a system of rollers, where the steering roller and the pressure roller with the sides of the lever form a two-arm lever relative to the axis of rotation fixed in the brackets of the base fastened to the turnstile frame © Distance "d" of the axis of rotation of the two-arm lever from the axis of the turnstile drum "L the distance "the axis of rotation of the steering roller and the pressure roller satisfies the relation d1. The length of the segment 0 ^ 02 connecting the axis of rotation of the two-armed lever with the axis of rotation of the turnstile drum, minus R radius of the turnstile drum - distance "L". The device according to the invention is structurally simple and suitable for a variety of rope diameters. The subject of the invention is illustrated by an example of embodiment in the drawing, in which fig. 1 shows the device in front view, and fig. 2 shows the device in a side view. . As shown in the drawing, the device according to the invention is provided with a guide roller 1 mounted on an axis 2, the pins 3 of which rotate freely in the sides 4 of the levers. On the sides 4 of the levers, there are also supported spherical pivots 5 of the pressure roller 6. The rollers 1 and 6 with the sides of the 4-lever form two-arm levers which can be rotated about the axis 7 parallel to the drum 11 of the turnstile and fixed in the brackets 8 of the base 9, fastened to the frame of the turnstile. The pins 3 are secured against axial displacement. The pressure roller 6 has a chamfer at the angle of oC = 15 °. The selection of the rollers 1 and 6 spacing and the distance of the axis of rotation 7 of the double-arm door handle from the axis of the reel 11 of the turnstile affects the correct laying of the rope 10. Assuming that the distance of the axis of rotation of the steering roller 1 and pressure roller 6 is "L", and ¬ The depth of the axis of rotation 7 from the axis of the drum 11 of the turnstile Md ", the radius of the drum 11 of the turnstile is R and the segment connecting the geometrical axes of rotation of the drum 11 of the turnstile and the two-arm lever 0 * 02, there is a relationship d L and L ^ 0 ^ 02 - R with the spacing of the rollers 1 and 6 with respect to the axis of rotation 7, such as 3: 5, the rope 10 is wound on the reel 11 of the winch in a slurry manner. The pressure of the rope 10 on the guide roller 1 presses the roller 6 and the correct positioning of the rope 10 and the bevels on the pressure roller 6 ensure " rope return 10. Patent claims 1.
