    A mobile device for generating acoustic shear waves comprises a structure provided with at least one axle with wheels mounted thereon, said axle being displaceable with respect to at least a part of the structure. The mobile device has mounted thereon a target-member displaceable from a position suitable for transportation to a working position where it is in contact with the earth, and means for striking the target member, when in working position, by means of a mass, to produce an impact thereon. The target member is provided at its upper part with tracks for the wheels of the axle so that the wheels can be driven, by displacing the respective axles, from a position of contact with the earth to a position where they bear on the target member with the weight of at least a part of the structure.

    专利说明:

    The invention relates to technical means for seismic research and can be used to create shock excitation sources. It is known a device intended to create transverse sound waves and a containing element of the target with a surface for contact with the ground, and a mass for applying impact on the target element in a direction parallel to the surface of the earth 1. However, this device is characterized by low speed. Closest to the present invention is a device for connecting with the earth of a target element, mounted on a vehicle and containing a surface for contact with the ground, side impact surfaces and tracks for the wheels of the vehicle, and the target element is connected to the mass and to communicate this mass of movement directed to the lateral surfaces of the cell element. To connect the target element to the ground, it is placed on the ground at a selected location and removed from the pivotally connected levers, which are held by dt. its in the transportation position. The vehicle is then guided in such a way that its tail chassis, which in this case consists of two axles, is aimed at the target element and fixed. Then, the mass that hits the target element with the greater efficiency in terms of transferring seismic energy to the ground is released, so that the rear part of the vehicle’s transport presses its weight on the raceway 2. However, this device has the disadvantage that each firing operation must be preceded by maneuvering the vehicle to provide a rigid connection of the target element to the ground, and because of this maneuvering, the frequency of possible repetition of successive mass releases is reduced. The purpose of the invention is to increase the speed of the device,
    The goal is achieved by the fact that in the device for connecting the target element to the ground, mounted on the vehicle and containing a surface for contact with the ground, side impact surfaces, impact weight and raceways for the vehicle wheels, the target element is connected to the impact mass and with means for communicating this mass of movement in the direction of the side surfaces of the target element, the vehicle comprises at least one axis configured to move between the first false in which the wheels placed on the ground, and a second position in which the wheels placed on the rolling track, and propulsion means for moving the axis,
    . In this case, the motor means for moving the axle contain at least one jack, the casing of which is fixed on the vehicle, and the rod is fixed on the axle.
    The means for moving the axle comprise an engine and a transmission system for connecting the engine to the wheel 1 1I.
    The axis, which is made with the possibility of movement, is connected to the target element by cables, supported by a stream, a pulley, the axis of which is fixed to the vehicle.
    If the device has two axes that are movable, they are located on both sides of the target element and are movable in opposite directions.
    The vehicle contains at least one part that is movable and rigidly connected to the axle being moved ,.
    FIG. 1 shows the device at the moment when the target element is in the upper position, and both axes are moved apart — in FIG. 2, the same at the moment when the target element is in contact with the ground, and both axes are in the shifted position. pressure on the target element; in FIG. 3, the same, in the position when it presses on the target element, side view; at FI1.4 node I in FIG.
    The device comprises a structure 1 mounted on two axles equipped with wheels x 2 and 3. The structure supports mass 4 and means allowing it to communicate speed with a certain amplitude. These means consist of a control lever 5, one end of which is rigidly connected to the mass, and the other end is installed rotatably about the axis b, rigidly connected to the platform 7, in a plane, perpendicular to the structure.
    The platform 7 is rotatable with respect to a head rigidly connected to the structure 1, the axis of rotation being perpendicular to this structure. Motor means forcing the lever 5 and the platform to rotate. 7 are not shown in the drawings.
    0 In addition, ..., the device contains a target element 8, provided on its side walls with impact surfaces 9 and containing in its upper part a raceway 10
    5 for axle wheels on which the structure is mounted. The raceways are profiled to make it easier to lift the wheels onto the target element,
    Motor means, made in the form of ropes / or chains 11,
    fixed, fixed in the upper part of the target element and resting on end pulleys 12 and 13, the axes of which are fixedly fixed, respectively
    5 in the upper part of the structure on the vertical of the target element and in its lower part at the height of axes 2 and 3, these latter contain attachment points for the second end of the ropes or chains.
    Each axis contains two guides.
    14 {FIG. 3 and 4) on the one and the other side of the longitudinal axis of the structure. They are made slidable along two guide rails 15 fixedly mounted in
    the lower part of the structure parallel to its longitudinal axis.
    The propulsion means intended for moving the axles are contained by the jacks 16, the shells of which are fixedly mounted on the structure, and the rods are fixedly mounted on the axles 2 and. 3, the jacks. directed in such a way that as a result of their simultaneous expansion both axes approach each other, and the target element is lowered. The means of pressure located on the structure (not shown) ,. the democrats are allowed to set in motion, in the upper position the target element rests on the stoppers 17 rigidly connected to the structure.
    The distance between the axes in their approach position is chosen so that it is less than the length of the target element. Similarly, the maximum distance between the two axes corresponding to the position s. reverse or reverse rods of jacks, selected greater than the length of the target element. The creme of that. the length of the ropes or chains is chosen in such a way that the distance 5 between the axles exceeds the length of the target flamen when a pull force is applied to the latter.
    The device works as follows.
    The jacks 16 are brought into action so as to bring both axes 2 and 3 closer to one another and at the same time lower the target element. The latter comes in contact with the ground. As the pressure of the jacks on the axle continues, the wheels go up along the raceways 10 (Fig. 2) and force the structure 1 to press its weight on the target element 8, Then the operation of oscillation can be performed.
    The movement of the device from one place of excitation to another is carried out as follows.
    The reverse stroke of the blunt rods 16 is turned on, with the result that both si are moved one from the other, the wheels are lowered to the ground. As a result of the increase in the duration of the return stroke movement of the domrat rod on the ropes or chain 11, pressure is applied to the target element 8. The latter rises to its upper limit of the position by which it is blocked by the stoppers 17 (Fig. 1). Moving structure 1 is ready to move.
    In variants of the device, both jacks can be replaced; by any other motor means capable of causing the front and rear wheels to grow in opposite directions. You can use a hydraulic motor connected to a hydrostatic gear of a known type .. Then, in the position of movement of the device, both axes 2 and 3 will be fixed with respect to structures 1, and the wheels will be rotated in the same direction. In order to force the wheels to rise on the tracks of the target element, the axles are disconnected with respect to the rigid structure and the opposite direction of the hydraulic transmission applied to the wheels, for example, the front axle 2, is applied. The drive of the hydraulic motor causes the two axes to approach each other. and lifting the wheels on the target element. In the same way, changing the direction of transmission to the opposite, after each excitation, both axes return to their initial blocked position. It is also possible to implement a device equipped with two axes, of which only one can move and lift onto the target element and apply to the latter a part of the weight of the structure 1,
    In a similar way, it is possible to make the movement of one or both axes and the target element independent of one another, controlling their movements with independent motor means.
    In the above-described embodiment and in its variants, the structure used is rigid, and the axes are adapted to be displaced relative to the latter. However, it is also possible to replace the rigid structure 1 with a deformable structure, with which one or both axes are rigidly connected. This design can be
    5 is made of dzeuk parts, each of which carries one of the axes, and these parts can move one relative to the other.
    In addition, the structure can be moved by trailer
    0 means or be self-propelled. The propulsion means allowing the vehicle to be moved may be independent of the axle displacement means and the target element.
    5 (case of use of jacks 16) or to be the same, {the case in which they act directly on the wheels by means of hydraulic transmission, for example, for
    0 in order to raise them on the element of the target 8),
    The proposed device is characterized by high maneuverability,. which speeds up the installation
    5 target element at the point of excitation and thereby increase the speed of the device.
