Description

The invention relates to cable-laying equipment and can be used with devices for laying a cable or flexible pipeline.

The purpose of the invention - increasing the efficiency of cable laying notation ⁵ rudovaniya by optimizing the trajectory vibronozha oscillations depending on the physico-mechanical properties of soils developed.

FIG. 1 shows the working equipment for cutting the soil, a general view; in fig. 2 — node I in FIG. one; in fig. 3 - a topic of vibration of the working equipment.

The cable-laying equipment contains a non-15 • ear frame! Mounted on the base chassis, a sub-hinged four-hub 2 mounted on it, one vibration link 4 attached to one of the vertical links 3, connected to the unbalanced vibrator 5 its ₂ θ oscillation, which is fixed on the link 3 nsgärker 2. The vibrator 5 is duhnalny, directional and connected to the vibrator 4 by means of a crank mechanism mounted on the shaft of the vibrator 5, consisting of a crank-25 thorn 6 and a connecting rod 7. The length of the crank 6 re it is guided by a permutation of the axis connecting it with the connecting rod 7 (see Fig. 2). Fixing the crank 6 on the shaft of the vibrator 5 is carried out using a spline connection. The fixed angular displacement of 30 hryvoshpa 6 relative to the unbalances of the vibrator 3 is carried out due to the displacement of the irradiator 6 at the splined joint of the shaft of the vibrator 5 by an angle of 0-2 l rad. The vibrator 5 is powered by engine 8, for example a hydraulic motor. On one vertical link 3 55 hinged four-link 2 by means of parallel strings 9, a cable cassette 10 is hinged, and the second vertical link of this four-link 2 by means of hinge 11 is connected to frame 1 with the possibility of ₄ θ turning in horizontal plane.

Cable-laying equipment works as follows.

Upon rotation of the output shaft ⁴⁵ dvigate- A vibrator 8 5 generates driving force, under the action of a link quadrilateral 3 with 2 vibronozhom 4 is moved in the vertical plane (vertical component trajectory of elliptical vibrations). At the same time, the crank 7 of the crank-connecting rod mechanism, acting on the vibro-blade 4, causes it to oscillate in the direction coinciding with the longitudinal axis of the base machine (the horizontal component of the elliptical oscillations). As a result of the addition of two in-phase components of the vibration vibration path 4 in mutually perpendicular directions, the toe describes the trajectory in the form of an ellipse, one of the axes of which is parallel to the longitudinal axis of the base machine. At a given rotational speed of the unbalance, changing the shape of the path of movement of the toe of the vibrator 4 in the vertical direction is done by increasing (decreasing) the driving force of the adjustable unbalance vibrator 5 (by a corresponding change in the eccentricity or mass of the unbalance), and in the horizontal direction by changing the amplitude of vibration of the vibroranch 4 relative to the link 3 of the 4 due to the permutation of the crank 6 relative to the connecting rod (Fig. 2). The rotation of the elliptical trajectory of the movement of the toe of the vibronod 4 around the point of intersection of the axes of the ellipse is due to the phase shift of the unbalance rotation by shifting the crank 6 relative to the unbalance by an angle of 0-2 π rad.

FIG. 3 letters a, b, c, g and d indicate some variants of elliptical vibration vibration paths 4 with different rotation of the ellipse axes around their point of intersection due to the angular displacement of the crank 6 and the different ratio of the vertical Ay and horizontal oscillations:

<p - 0.5 l, Ah = 0.5 Ah; ψ = 0.4l, Αχ = 0.5Ay; φ = 0.3 l, A _x = Ay φ = 0.2 l, A _x = 1.5Ay; φ - 0, A _x = 1,5A;

Vibration loads on the cable cassette 10 of the vibrator 4 are absent in the horizontal direction, in the vertical direction they are weakened due to the articulation of the cassette 10 with the link 3 of the 4-link 2. Excessive power consumption and overvoltage in the structural elements of the cable laying device resulting from maneuvering during cable laying in cramped conditions, are reduced due to the hinged connection, the vertical link of the four-trestler 2 with the frame 1 in the horizontal plane.

Cable-laying equipment allows to obtain elliptical trajectories of the movement of the toe of a vibro-blade of any shape and, depending on the physical and mechanical properties of the soil being developed, makes it possible to realize the optimal trajectory.
