Description

The utility model relates to mining, in particular to devices for exploration drilling in the exploration of minerals on the seabed. The device can also be used for geological exploration, drilling rocks with a complex relief of the field, development of peat deposits.

Known devices for moving mining working bodies under water using ropes or caterpillars of caterpillar, wheel and screw type (Walking machines for the development of the resources of the seabed. L., 1987, p. 12-17).

The disadvantages of these devices are the difficulty in providing the required trajectories of the movement of the working bodies with continuous mining of minerals, as well as environmental damage while leaving tracks of tracks, wheels and screws.

Known mining walking device for underwater mining of minerals capable of transporting working bodies along certain trajectories (copyright certificate SU No. 1027343, E02F 3/88, publ. 07/07/1983), including a farm mounted on two supports with a towing cart and a turning mechanism .

The disadvantage of the mining walking device is that to ensure the movement of the device requires a special traction trolley with a load, the rotation restriction mechanism is an emphasis at the ends of the truss consoles, and the supports are made in the form of arcs. This design significantly complicates the design, creates additional resistance when turning the device, reduces the stability of the structure.

A known installation for the development of nodules of silts and placers from the bottom of the seas and oceans (copyright certificate SU No. 1099081, E21C 45/00, publ. 23.06.84), in which the frame is equipped with a mechanism for the transverse drift of one end relative to the other.

The disadvantage of the installation is the supporting frame, supported by two skis, which create additional resistance to the rotation of the installation in the horizontal plane and do not allow continuous development of the seabed in order to determine mineral reserves, since the zone of possible movement of the installation is significantly limited.

Known walking installation for sampling from the bottom of the seas and oceans (copyright certificate SU No. 1151675, E21C 45/00, publ. 04.23.85), containing a working body, a farm, a traction trolley of the working body with the possibility of longitudinal reciprocating motion, two supporting tables with vertical and horizontal hinges and rotation mechanisms.

The disadvantage of this device is the presence of a float, which greatly complicates the walking mechanism and limits the scope of the installation (only under water), in addition, the working body does not allow sampling with the necessary regularity.

Known mining walking device for underwater mining (copyright certificate SU No. 471452, E02f 3/88, publ. 25.05.75), adopted as a prototype, including a truss installed on two supports consisting of a platform and telescopic rods, a working body and management system. The farm is suspended from the lower surface of the platforms of supports and pivotally connected with them, equipped with brackets with rollers interacting with the fists mounted on the platforms of the supports movably, and the working body is equipped with a traction trolley to move it around the farm.

The disadvantage of this device is that the working body allows you to take samples only from the surface of the seabed and mine only in the area limited by the position of the supports, which reduces the performance of the installation as a whole.

The technical result is to simplify the design of the device, to ensure the movement of the working body of the drilling rig along the entire length of the farm, as well as creating the possibility of sampling at different depths of the surface of the seabed.

The technical result is achieved by the fact that the truss is made of two parallel pipes with longitudinal guides and equipped with earrings pivotally connected to the support platforms, while the ends of the pipes are rigidly interconnected by transverse beams with blocks placed on them, and the working body is made in the form of a cart with rollers, interacting with the longitudinal guides of the farm, with a drilling rig rigidly fixed on it and two winches equipped with flexible traction elements (for example, cables), covering blocks of transverse balls to, one end of which is fixed on the drum of the winch, and the other on the trolley of the working body.

The walking drilling rig includes a supporting truss 1 (Fig. 1) mounted on two supports 2 and a working body 3. The truss 1 is made of two parallel pipes 4 (Fig. 2), equipped with longitudinal guides 5 (Fig. 2, 3), having the shape of the channel, and in the lower part - earrings 6 (Fig. 3). The ends of the pipes 4 are rigidly interconnected by transverse beams 7, on which the blocks are placed 8. The truss 1 has a rectilinear section 9, and the ends of the truss are bent upward, forming symmetrical consoles 10, left and right (Fig. 1, 2). The working body 3 is made in the form of a trolley 11 (Fig. 2, 3, 4) with rollers 12. In the lower part of the trolley 11 is equipped with eyes 13. A drilling rig 14 and two winches, the right-hand drive 15 and the left-hand drive 16, are equipped with trolley 11 flexible traction elements. 17 (ropes) covering blocks 8 of the transverse beams 7, one end of which is fixed on the winch drum, and the other on the eyes 13 of the carriage 11. The rollers 12 of the carriage 11 interact with the guides 5 of the carrier farm 1 with the possibility of reciprocating movement of the working body 3 along the farm . In this case, it is possible to move the working body along the entire length of the truss, including the console 10. Each of the supports 2 (left and right) consists of a support table 18 (Fig. 1, 3), equipped with telescopic rods 19 with support shoes 20 and platform 21, made with forks 22. The turntable 21 is supported on a support table 18 by means of cylindrical rollers 23 and is connected with it by a vertical axis 24 with the possibility of relative rotation. On the support table 18 there is a drive 25 for turning the platform 21, including an open gear train consisting of a gear 26 and a gear wheel 27 rigidly connected to the vertical axis 24. The earrings 6 (Figs. 1, 3) are connected to the forks 22 of the platforms 21 using axes 28, forming a hinge joint of the truss 1 with the supports 2.

The work of walking rig is as follows. The device is installed on the drilling site (Fig. 5) (for example, on the surface of the seabed, pit ledge, etc.) and the drilling process begins in accordance with the specified drilling passport. After the first well has been drilled, the drilling rig 29 of the drilling rig is lifted (Figs. 1, 5), the drive of the right winch 15 is turned on, and the working body 3 is moved to a new position along the guides 5 of the supporting truss 1 at a distance S corresponding to the location of the exploration wells. Then drill rig 29 is lowered and the next well is drilled.

The process continues until the working body 3 reaches the right console 10 (Fig. 7, 8). When the working body 3 reaches the end of the right console, the left support 2 is torn off from the seabed, the carrier truss 1 rotates in a vertical plane relative to the hinge axis 28 by an angle φ (Fig. 7). In this position, the drive 25 rotates the platform 21 (Fig. 3, 8) of the right support 2 and rotates the truss 1 at an angle β in the horizontal plane (Fig. 8). Next, the drive of the left winch 16 is turned on and the working body 3 begins to move towards the left console 10. As soon as the working body 3 is shifted from the end of the right console 10, the condition of equilibrium of the system is violated and the raised left support 2 is lowered and mounted on the seabed in a new position (Fig. . 8). Begin a new cycle of drilling wells by sequential movement of the working body 3 along the farm 1 along the guides 5 in accordance with the drilling passport. At the end of the development of the next entry, the walking cycle is repeated by moving the working body 3 to the left console 10 (Fig. 9, 10).

The movement of a walking drilling rig by changing the position of its center of mass by moving the working body from one console to another allows you to drill wells in accordance with a specified drilling passport along the required paths - angular, straight, circular, parallel and others in order to determine mineral reserves.
