    The purpose of isopheny is to simplify the design of the device. The goal is achieved by the fact that in a device for exciting elastic waves in the ground on a vehicle that contains an impact mass, an elongated guide element to control the movement of the mass to the target, while the target is fixed on one of the condoms of the guide element - a jerky mass retention is fixed on the guide element near its other end; means are introduced to transfer the guide element between the first position in which the Mars can move under the action of its own gravity from the second end of the guide member to mshpeni situated at a first end of said guide member, with ego mischen in the first position is connected to ground, and a second position in which the mass under. the action of its own gravity moves from the first end of the guide element to its second end, on which retaining means are mounted and vice versa. In this case, the means of movement of the guide element are implemented in the form of a system with a rigid support placed on the vehicle frame and containing at least one holder connected to the guide element and with the support, and a device for rotating the holder around a certain axis of rotation. In addition, the device may contain at least two fastening elements connected to a guide element, one of which is rotatable relative to the axis of rotation, and the other relatively rigid support, with The hydraulic means comprise a jack for turning the second fastening element with respect to a rigid support. Fig. 1 schematically shows a device with a guiding element installed in the first position (in this position the Miss is held by means of retaining means) in Fig. 2 the same, top view; in FIG. 3, the same, with the guide element in the first position, when the mass, after starting, is in contact with the target; 4 is the same, with the guide element in the second position; in fig. 5 - a device located on an inclined plane, with the direction of the lowest element Nahrdvts in the first: PB oriented in vertical orientation; In FIG. 6, a system for driving a /, guide element. Figures 1-5 show a guide element consisting of a guide pipe 1 inside which some mass 2 can slide with some gap, at least a part of which is made of metal. At the first end of the guide tube 1, a fastening system 3, reinforced preferably on the hinges, is fastened with a fastening system 3. This fastening system may include a ball joint 4, the outer part of which is connected to the mouse and can rotate in a slot located in the end part of the pipe 1 The springs 5 provide 1 a clearing of the mallee 3 to the end part of the guide pipe 1. The opening 6 in the wall of the guide pipe 1 serves to communicate its lower part with the external medium and provides free flow of air compressed when the masses fall. s on the target. The guide tube is supported by a sleeve 7 having the shape of a cylinder (Fig. 6), the diameter of the inner cavity 8 is larger than the diameter of the tube, and in the lower part of the sleeve there is a slightly taper hole 9. The guide tube 1 has two retaining lugs 10 and 117 located on two sides of the cylindrical sleeve 7, and the distance between the retaining protrusions exceeds the height of the sleeve. The shape of the retaining protrusion 11 corresponds to the shape of the conical hole 9. A ring 12 made of rubber or plastic, the diameter of which is approximately equal to the diameter {) of the inner cavity 8 of the cylindrical sleeve 7 is provided to the outer wall of the guide tube 1. guide pipe inside the coupling. Within the stroke length, limited by the diameter of the tapered bore 9, the guide tube 1 can tilt inside the cylindrical sleeve 7 and maintain a vertical position when the sleeve is tilted to one side or the other from the desired position. In the cylindrical coupling 7 there are sockets for two axes 13 and 14 (Fig. 1-5). On axis 13, the holder 15, which has the shape of a letter U (shown, in particular, in Fig. 2), is pivoted around. The two shoulders of the holder are 15 mo "; they rotate around the axes 16 fixed in the lateral spars of the nejmoro holder 1 and the rigid elongated frame 17. On the axis 14, the second rotates
    The holder 18, represented by itself, is a plate of approximately triangular shape. One of the vertices of the plastigal 18 is connected by an axis around which the rod 19 of the jack 20 can rotate, which is attached to a rigid elongated frame near one of its ends. At the same end of the elongated rigid frame 17 there is an outer part of the ball joint 21, the inner part of which is connected to a movable part or a slider capable of moving. The guide 22 is attached to the second frame 23, which is, for example, located on the chassis of a vehicle, for example, a truck. A second rigid frame 23 can also be equipped with legs and placed on the ground at a selected location. In this case, the installation can be transported by helicopter or by any other vehicle. Guide 22 is oriented on a strictly longitudinal axis of the vehicle. An end of the rod 24 of the jack 25, which pivots around an axis on a second frame 23 mounted on the vehicle chassis, is attached to a movable part or a slider rigidly connected with the outer part of the ball joint.
    Near its other end, a rigid frame 17 is attached to an elongated element or a tubular curved holder. 26, the bending center of which passes through the ball joint 21. On both sides of the longitudinal axis of the vehicle and parallel to it are two directions of the axis 27, which are part of the frame 23, inside which two moving holders or slides 28 slide. JflBa movable holders 28 have holes or gaps 29, which includes a tubular holder 26.
    The rigid frame 17 has an axis for the hinge rotation of the SO of the rod 31 of the transverse jack 32, which is globally fixed by the axis on the frame 23, fitted to the vehicle chassis (FGM 2). The third top of the carrier plate 18 can rotate on the axis 33, which is towards the flat part of the tubular holder 26. The rigid frame 17 also contains the surface of the support 34 in the vicinity of the ball joint 21, which lies in its second position, which is also the position transporting the installation, the end of the guide tube 1. At the second end of the guide tube 1 are located the means 35 for holding the mass 2, containing, for example, an electro-magnetic.
    Three jacks 20, 25 and 32 are powered by a hydraulic system (not shown).
    In addition, the device comprises means for monitoring the verticality of the guide tube in the firing position. These means comprise two sensors Verticals 36 and 37 located on guide tube 1, the axes of which are respectively perpendicular to the hydraulic jacks 25 and 32. These sensors are, for example, electromagnetic taps of a known type. The sensors are connected with an electronic device, controlling two electronic valves that actuate the hydraulic jacks 25 and 32, respectively, until the guide tube is in the vertical position. Means of controlling the verticality of the sensor, interacting with the sensors, are shown in the drawing.
    In addition, it is preferable that the weight of the used mass 2 lies within 0, 5-1.5 times the weight of the sheet. It should also be close to the target weight. The material from which the target is made is chosen so that its total acoustic impedance is well matched with the full acoustic response from the bottom of the base. The target can be made, for example, from cement poured into a metal tank.

    When the jack 25 comes into motion, the movable part, which is part of the female ball joint 24, moves along the non-guide 22 and draws into its movement the rigid rehearsal system 17 and, through the latter, the parts of the movable holder 28 sliding along the two guides 27 and the pivot points of the holders 15 and J8. In this way, the coupling 7 of the guide tube 1 moves parallel to itself and in a direction parallel to the longitudinal axis of the vehicle. When the movement comes, the jack 32 (Fig. 2) begins to rotate on the ball joint 21 of the rigid frame 17, which is involved in movement by moving the tubular holder 26 in the lumens 29 located in two parts of the holder 28. The movement of the coupling 7 along this also results. an arc of a circle centered on a ball joint 21 in the direction transverse to the location of the vehicle. The combined action of the two doctrines 25 and 32 causes the movement of the carrier 7 of the guide tube 7 in a plane parallel to the frame 23 located on the vehicle, and, as described, this makes it possible to transfer the tube B to the vertical position. In the described position of the rods of the jacks 25 and 32, the movement of the rod 19 of the jack 20 causes the shoulder system 15 and 18 to rotate around their axes of rotation 16 and 33, so that the guide element 1 passes from the first, preferably strictly vertical position (Fig. 1.3 and 5), to the second position (FIG. 4), in which its end with electromagnet 4 is below the other end. The device operates in the following manner. When transporting the device to the place where seismic shooting is to take place, the device is in the position izofazhennom in FIG. 4. To actuate the electromagnet 35 to fix the mass 2 at the end of the direction of the device opposite the target, then the main jack is actuated, re-shaping the head of the pipe into a strictly, vertical position (Fig. 1), which means that the tube can move relative to the coupling 7, it takes the position of vertical equilibrium, but if at the moment when the target enters. contact with the soil, the guide tube is not completely vertical, the jack 25 or jack 32 is set in motion, due to which the verticality of the target is achieved:. These actions can be carried out manually or, preferably, they can be controlled automatically. Using the described means of control, a vertical installation, designed according to isofetenis, can also be successfully used on a sloping platform (Fig. 5). The width of movement of the guide tube relative to the coupling allows it to maintain equilibrium with respect to the vertical. In all cases, with the help of households 25 and 32, an equal weight with respect to the vertical is provided when there is a deviation from it. . After completion of the installation operations, the pipe 1 is directed to the pipe 1 and the target is brought into contact with, the launch is started, and the weight of the mass striking the target 3 is dropped (Fig. 3). If shooting is to be done elsewhere, the main house 2Ot 2O is actuated to transfer the guide tube 1 from the first position, in which the target 3 is in contact with the soil, to the second position, in which the target 3 is located above the end of the tube with an electromagnet. The mass is lowered to this end by its own gravity and can be fixed again with the help of an electromagnet (Fig. 4). Claim I. Invention of a device for exciting elastic waves in the ground on a conveyor vehicle, a shock weight, an elongated guide element for controlling the movement of the mass to the target, fixed at one end of the guide element, and means for discontinuously holding the weight, fixed on the guide element at its second end, characterized in that, in order to simplify the structure, it is provided with means for translating the guide element from the first position in which the mass can move under the action of bstvennoy gravity from the second end of the guide target member, the target in this first position is in contact with the ground, to a second position in which the mass moves under the action of gravity from the first to the second guide yushego element and vice versa.
