Claims

20, through-cuts are made under the angle to the longitudinal axis of the conductor, ravaine or larger than the self-braking angle, with the locking elements fitted with fingers installed in the through-slots, the ends of which are fixed in the walls of the grooves, and the fixing elements are spring-loaded relative to the carrier plate. In addition, the gaskets are made step-wise, and the surface adjacent to the conductor is provided with longitudinal curves, the wedge-shaped ones forming the hole cuts are made with a greater angle than the self-braking angle. FIG. t shows a device for fastening conductors in a sleeper; in fig. 2 shows section A-A in FIG. in fig. 3 shows a section BB in FIG. 2; n FIG. 4 shows a section B-B in FIG. 2, in FIG. 5 is a section of YYD in FIG. 4. To the execution of 1 box or two sections with the help of bolts and a conventional yoke (not shown in the drawing; cauldron) the carrier plate 3 is attached; from the side of the conductor to the conductor it is made with box-shaped parallel grooves 5, in which stepped gaskets 6 are mounted , provided with holes, and from the side adjacent to the sole of the conductor, a longitudinal grooved surface. Fixed elements 7, made in the form of wedge-shaped plates with the angle of inclination of surfaces 8 to the sole of the conductor smaller than the angle of self-braking by 5-13 °, are inserted into these grooves. Elements 7 have limited waudai resistant surfaces 9 facing the sole of the conductor from both sides. The gradation of the gaskets 6 is provided to provide centering with the conductor 4 during installation. I On plate 3 there are tides 10 against which the upper ends of the gaskets 6 abut. Parts 6 and 7 are made of synthetic material. In the lower part of the elements 7, jacks 11 are provided, and in the middle center, through slots 12, taking into account the inclination to the longitudinal axis of the conductor, are equal to or greater than the self-locking angle cL in the plane perpendicular to the surface 8. Through the slots 11, the elements 7 are spring-loaded upwards by springs 13 resting on the perforated shelves 14 of the lower part of the box-shaped grooves 5, the lower ends of the gaskets 6 rest on the same shelves. The perforations of the shelves 14 do not allow accumulation in the grooves by accident and spilling. Through slots 12, fingers 15 (or sleeves with fastening bolts) with flats 16, interacting with slots as wedge slips on both sides of the longitudinal axis of the conductor, are passed. The ends of the fingers 13 are fixed in coaxial holes of the 17 walls of the box-like slots. To reduce the clogging of the box grooves, a cap of elastic material can be put on top of the profile of the conductor base (not shown). In the absence of mutual vertical displacements in the system, shooting conductor conductor 4 is held in the horizontal plane by elements 7 due to the interaction of surfaces 8 directed from two sides to the conductor, the action of wedge pairs 12 and 16 with fingers 15 brought by springs permanently acting with a given force through sockets I1 13, resting on the shelves 14, and additionally - gaskets 6, fixed in the slots of the grooves 5 by the tides 10. When the temperature increases the conductor 4 or its displacement due to the shafts of the barrel and the shaft surface, on which rigid fixation of the upper end of the solid conductor is implied, the latter, moving downward relative to plate 3, can only drag element 7 due to friction, which, in turn, when interacting with wedge surfaces pairs 2, 15 and 16 stimulates the expansion of these elements 7 along the planes B, which ensures better slippage of the conductor soles relative to the mount with a minimum vertical load on the reinforcement and on the walls of the shaft shaft, maintaining the overall weight fixing stability horizontally stable. In a similar way, the stability of fixing the conductor is preserved in terms of wear of contact with the conductor bottom of the conductor due to the constant selection of the springs 13 and wedge pairs of emerging gaps. In cases of less probable, but possible in roprfoM, movements of the conductor with respect to the shootings 5 upwards, arising in addition to jamming the force acting from the spring 13; the force is limited to surfaces 9, -the position, 1Mi, two sides of the sole of the conductor 4. Returning In this case, the load on the shooting will be negative, i.e. directed upwards. Thus, the load on the trunk reinforcement from mutual vertical displacements arising in all cases, regardless of the magnitude of the rock pressure, is limited by the frictional properties and the parameters of the wedge pairs 7, 8, 12, 15 and 16 and the parameters of the constant springs 13, ensuring that the greatest preservation of reinforcement and conductor from deformation and damage. Such properties of the proposed device allow to reduce the design and actual loads in the shooting-conductor system by at least 10-15 times, which, while improving reliability, reduces the metal consumption, while the device itself reduces the labor-intensiveness and maintenance of mine reinforcement.
