    The invention relates to devices for creating transverse acoustic waves in the soil, used in particular in seismic surveys. The aim of the invention is to increase the seismic efficiency by increasing the frequency of repetition of force effects and spreading the range of application conditions of the device.
    Figure 1 shows the device, a general view; figure 2 - the working node; FIGS. 3 and 4 are the same, the cross-section, respectively, in the working and transport positions; fig.Z - frame, type in the plan; 6 shows the target element, a plan view; 7, 8 and 9 are a rigid lever with a shock mass in the lower, upper and middle positions, respectively; in fig. 10, 11 and 12-power cylinder with valve in different phases of work.
    The device for creating transverse waves includes a rectangular-shaped target element 1 with a hole in the central part (Fig. 6). The target element can be a system made of metal beams rigidly interconnected and having a contact surface 2 laid on the ground. Coupling elements 3, teeth or. the protrusions may be filled on the surface of the overlay of the target element in order to increase the coefficient of adhesion of the latter to the soil. Metal plates 6 are mounted on two internal opposite walls 4, 5 (FIG. 3) of the target element, perpendicular to the contact surface 2. Damping elements 7 made of polyurethane are provided in the plates 6 that receive the impact. The device also includes a rigid lever 8 formed by two elongated elements. 9, each of which is connected at one end to a mass of 10 "and opposite to each other by means of a cylindrical part 11. Axis 12, rigidly connected to the lever 8, passes through both elements 9 and a cylindrical part 11. The device also includes a platform 13 formed by a plate 14 (FIG. 3) and two brackets or side panels 15, 16 (FIG. 2) perpendicular to the plate 14 and rigidly connected to the latter. At the end opposite to plate 14, both

    the sidewalls have round sockets for two disks 17 - (FIG. 2) made of some cushioning material (for example, polyurethane), and
    In the center of each disk, there is also a hole in which one end of the axis 12 enters. On the plate 14, a gear ring 18 is mounted, capable of being rotated relative to the ring bracket 19 (Fig. 3) with the help of ball bearings (not shown). The ring bracket 19 is part of the first rigid frame 20, which also includes (Fig. 8, 4 and 5): the node formed by two beams 21 and 22, the ends of which are rigidly connected by means of two other beams 23, 24, and the middle parts - using two more beams 25, 26 (ring bracket 19 is attached to beams 25 and 26); two beams 27, 28 parallel to beams 23, 24 and connected to the latter by means of truncated parts

    and installed perpendicular to the plane of the latter. The second ends of these four columns are rigidly connected to a second rigid frame 31 of rectangular shape, formed by parallel rigid beams 32 and 33, rigidly connected to each other by two tubular partitions 34, 35 (Figures 2, 3) by means of fittings 36. Two rigid frames 20 and 31 and four, columns 30 form a rigid frame.
    The rigid beams 32, 33 of the lower rigid frame include each (FIG. 4) a first support partition 37 and a second support partition 38, which is installed perpendicular to the first one. Deformable elements 39, representing, for example, containers of elastic material filled with compressed air, are installed, on ONE side, in two different places of each of the support walls 37 and, on the other hand, on the upper surface of the target element 1 in four the corners of the latter (6), thus forming the first elastic connection between the target element and the frames in the first direction. The same deformable elements 40 (FIG. 4) are strengthened, on the one hand, in two different places of each of the support lines.

    town 38 and, on the other hand, abut against supporting walls 41, mounted parallel to the impact plates 6 of the target element and rigidly connected to the latter so as to form a second elastic connection between the target element and the frame in a direction parallel to the plane of mass rotation and - perpendicular to the first direction. The chains covered by the covers 42 (FIG. 2) are fixed, on the one hand, to the target elements and, on the other hand, to the second rigid frame 31, in order to limit the vertical expansion of the deformable elements 39 when they are holding the target element 1 by weight. Torsion bars the rods 43 are mounted with the lower rigid frame 31 and the stop parts 44 provided on the target element in order to prevent any displacement of the latter in the direction perpendicular to the plane of rotation of the lever (the axis of the car).
    The lower rigid frame is provided with two fastening parts 45 (Fig. 3, 4) fixedly fixed in the middle part of the beams 32, 33. The rods of two jacks 46 (driving means) are connected to these fastening details. Damping elements 47 (Fig. 4) may be installed between the walls of the fastening parts 45 and the supporting plates 41, limiting the lateral displacement of the target element relative to the lower rigid frame 31 and excessive deformation of the joining means (deformable elements 39, 40). The housings of both jacks are connected to the chassis 48 of the car. An automotive hydraulic system (not shown) provides power for jacks with pressurized fluid. Four couplings

    baking the direction of the four columns 30, when the jacks 46 are powered.
    In addition, the device includes a gear wheel 50, which is engaged with the ring gear 18 and driven in rotation by an engine 51 mounted on an upper rigid frame 20.
    The rigid lever 8 control means includes: three gears 52 (FIG. 3, 4) rigidly connected to the cylindrical part 11; three chains 53 put on three gear wheels50

    ca 52 and connected at one end with the stem 54 of the jack 55, the body of which is mounted on the axis 57. In the plate 14 of the plastform, a hole 58 is made (Fig. 5) for the passage of the body of the jack 55. There are also two bearings 59 in which the axis 57 is installed connected to housing 56.
    Inside the housing 56 of the jack 55 (Figures 10-12), the valve 60 is rigidly mounted on the rod 54, the cross section of which is smaller than the internal section of the housing. Between the valves 60 and the lower end of the body, where the rod 54 is connected to the chains 53, a free piston 6.1 is installed, capable of moving inside the jack body while ensuring tightness. A jack 62 is made in the upper jackplate of the jack body, the cross section of which is smaller than the valve cross section and in which the valve rests when the stem 54 is fully extended. A notch 63 is provided in the jack 62 communicating with the hydraulic system mentioned by means of the tube 64. at the lower end of the housing 56 (Fig. 10) to the second position, in which it is pressed against the valve 60, which is in contact with the socket 62 (Figures 11, 12). Two tubes 65 and 66, respectively, extending into the opposite ends of the jack body and also communicating with the hydraulic system, supply the pressurized fluid to the inside of the jack to move the piston freely from one extreme position to the other.
    The dimensions of the platform 13 and the length of the rigid lever 8 correspond to the dimensions of the cage and the dimensions of the target element so that in both positions of the axis 12
    lever, symmetrical with respect to
    the longitudinal plane of the vehicle, the mass would be in the lower position in contact with one of the striking plates 6 of the target element or with the corresponding damping element 7. On the other hand, the length of the lever 8 is adjusted so that all movements of the mass 10 fit inside the volume bounded frame and chassis cars.
    The angle formed by the lever 8 vertical in the upper position can be changed in order to regulate the force of impact. According to preference5131
    For the preferred embodiment of the isobena, the change in the angle of mass rotation is provided by separating the lug seat 60 and the wall of the jack body. Its means of moving from the first position and at the upper end of the jack body to the second predetermined position, indicated by the stop mounted on the side wall of the case, are hydraulic means. The first position corresponds to the maximum angle of rotation, and the second - the minimum. For example, these angles can be 117 and 88, respectively. You can also choose any position within this angular sector by moving the seat to a certain intermediate position and mechanically locking it using stoppers of appropriate sizes.
    In accordance with another embodiment of the invention, the maximum angle of rotation of the rigid lever 8 can be changed by adding (or decreasing) one or several links in the chain 53.
    The device works as follows.
    Upon arrival of the vehicle, two jacks 46 are actuated in order to transfer the rigid frame from its upper position (second position) to its lower position (first position), in which target element 1 is pressed to the ground. It is preferable to create such hydraulic pressure in both jacks so that a part of the weight of the car presses against the target element in the working position to ensure a good acoustic contact.
    The motor 51 is actuated in order to rotate the platform and set it flat; the levers are turned to the first position (Figures 4 and 7). Until
    the lever 8 is in the lower position, the mass 10 is in contact with the shock-absorbing element 7 of one of the striking plates 6 of the target element. The shock 54 of the jack 55 is in an extended position (Fig. 10) when the valve 60 rests on the free piston 61 and occupies its first position in the lower part of the jack body 56. A tube 65 is supplied with pressurized fluid in order to move the piston 61 to its second position. When moving, the porsche takes along
    6326
    U1apan 60 and jack rod 54, as a result of the chain 53, tighten and turn the rigid lever to its upper position (Fig. 8), in which the valve
    rests on the seat 62, and the free piston 61 is pressed against the valve (Fig. 1 1).
    In tube 66, high hydraulic pressure is created while at the same time creating weaker hydraulic pressure.
    the pressure in the tubes 64 and 65, with the result that the xgapan 60 is pressed against the seat 62, and the free piston is re-. placed in its first position (Fig. 12).
    5 A fluid 64 is supplied through the tube 64 into the recess 63 of the seat 62, the pressure of which is higher than the pressure in the jack body between the free piston 61 and the valve 60, the valve slightly moves away from its seat 62. As a result, the pressure of the fluid on both sides of the valve is balanced. Since the valve section is smaller than the internal section of the jack body 56, the fluid
     can flow freely from one side of the valve to the other. As a result, the braking force of the jack 55 when extending its stem is almost zero, which allows the mass to freely fall down to its lower position, in which it collides with the striking plate 6. Under the action of a side impact, transverse elements are transferred to the target element seismic waves. The deformation of the connecting means formed by the inflated bags 39, 40 interfere. that the strikes inflicted on the target element are transmitted to the rigid 5th cage and the chassis of the automobile.
    Dp creating seismic transverse waves with opposite polarity in the soil is driven by the motor of the DNP 51 turning platform 13 to 45 180 ° to a position symmetrical to the position shown in FIG. 3 where the mass is in contact with another hit plate 6 or its shock-absorbing element, and repeat the described operations with the lever 8 and its lifting jack 55.
    After completion of the research and acquisition of seismic data in one place, the driving means (jacks 46) are actuated in order to set the frame in the upper position (Fig. 1), after
    7 13
    What the car is ready to move to a new place of research.
    It is advisable to equip the device with a control system that provides automatic execution of various movements of the frame and rigid arm. In addition, air bags 40 (FIG. 4) can be replaced with bellows filled with compressed air, the side wall of which can be deformed, and the axis is oriented parallel to the plane of rotation of the rigid ridge.
    The use of the invention allows to increase the repetition rate of force effects and to apply the device in conditions when the space for lifting and dropping the shock mass is limited.
