Description

one

The invention relates to the field of mining, in particular to equipment for drilling holes and loading rock mass in the mine workings.

The known boropogruzochny machine, including a chassis, a long-hole drill, a manipulator, a guide frame for moving the manipulator, pivotally connected to the frame of the chassis and equipped with a lifting cylinder l .10

The drilling in width is ensured by moving the manipulator in a horizontal plane, as well as by maneuvering the loading machine. To drill at the height, the guide rail moves in a vertical plane with the help of a power cylinder.

The lack of a drilling machine in the low reliability of the design is due to the significant cantilever drilling of the 20 via bus.

Closest to the invention in technical essence and the achieved result is a barge-loading machine, including a chassis with a frame, on which are mounted

The loading unit and the conveyor, and on the frame, are arranged longitudinally inclined mounted guides along which the trolley with perforators 2 moves on the rollers by means of cables,

The disadvantage of the machine lies in the fact that the height of the suspension of the drilling equipment remains unchanged relative to the production soil, and in this connection the drilling of the upper part of the bottom is limited by the length of the manipulator. Increasing the length of the latter requires an increase in the length of the movement of the drilling equipment in order to drive it away from the bottom up during the loading period.

In addition, the design of the drilling machine does not allow the transfer of drilling equipment to devices for placing this equipment on them during loading.

The purpose of the invention is the most rational movement of drilling equipment in the wellbore zone with minimal time and labor.

This goal is achieved by the fact that the proposed loading machine is fitted in series with uvainnymi profile beams n lifting boom, pivotally mounted on the frame of the chassis of the machine and pivotally connected to the profile beams. At the same time, one of the profile beams is connected to the conveyor frame through the roller supports and is made of parts connected by a vertical hinge, and the other is connected via a power cylinder and a lever parallel to the connecting rod. FIG. 1 depicts an alternate drilling machine, side view; in fig. 2 the same, top view. The forklift truck consists of a frame with a chassis 1, a loading body 2 and a frame with a conveyor-3. A rack 4 is rigidly fixed to the chassis frame, to which the lifting boom 5 and the parallelogram of the ha 6 are pivotally attached. associated with the frame of the chassis 1 and with the profile beam 8 connected through the lever 9 and the power cylinder 10 with a parallelogram thrust 6; The lifting beam 5 also hinges the profile beam 11 consisting of two parts 12 and 13 connected vertical hinge 14. Part 13 Alk 11 is connected via roller bearings 15 to the frame of the conveyor 3. On part 13 of the beam, guide bar 16 is rigidly fixed in contact with the grooves of roller 17. Chassis 18 equipped with rollers 19 and st Axles 20. Carts 18 are equipped with mounted storm equipment .21. On the axis 2O fixed cargo lines 22 variable plina. Before starting drilling, the drilling equipment 21 on the track rollers 19 moves from the profile beam 11, the lifting boom 5 to the beam 8 by means of a cargo sling 22 connected by a drive of the conveyor to its chain. Moreover, the elements 5, 8, 11 form a single guide beam, which occupies a horizontal position. Then the equipment is fixed from linear movement by the known method {and, and the beams 11 8 and the lifting boom 5 keep it from turning in a vertical plane, since the running rollers of the attachment are located in the profile of these beams. Drilling equipment 21 is adjusted to the point of drilling with the help of the beam 8, turning it with the power cylinder 10 in the vertical plane. The power cylinders 7, which are connected hydraulically between themselves through the hydraulic distributor, move the boom 5 in a vertical plane and the profile beams 8 with attached drilling equipment 21 located on them with preservation of its initial position. After finishing drilling with the help of cylinders 7 and 1O, lift the lift-shot 5 and profile beams 11 and 8 to a horizontal position, and move the weightless drilling equipment 21 to drive the machine conveyor through the sling 22 to the middle part of the machine or transfer this equipment to devices for its placement at the time of blasting and cleaning of the rock mass. It is possible to move the mounted drilling equipment any way known. When rotated during loading of the conveyor 3 in a horizontal plane, part 13 of the profile beam 11 rotates relative to part 12 due to the vertical hinge 14, and the beam part 13 is linearly displaced by means of the guide bar 16 and the roller 17 in contact with it. In the vertical plane, the beam 11 is rotated together with the conveyor around the hinge attachment of the beam 11 to the stand 4, and the linear movement of the conveyor 3 and the beam 11 relative to each other is also provided. After the end of the harvest, the rock mass is repeated in the order described. A forklift truck allows you to reduce the time of auxiliary operations, improves the conditions for turning the slab, and ultimately allows you to increase productivity in tunneling works. Formula of the Invention Boropogruzochny machine, including a frame with a chassis, a loading body, a frame with a conveyor and attached drilling equipment, characterized in that, with the aim of the most rational movement of drilling equipment in the drilling area with minimal time and labor. connected by profile beams and a lifting boom, pivotally mounted on the chassis frame of the machine and pivotally connected to the profile beams, with one of the profile beams through roller supports The frames are connected with the frame of the conveyor and are made of parts connected by a vertical cannon, and the other is connected via a power cylinder and a lever with a parallelogram t.
