Description

 The invention relates to mining. It is designed to work together with a continuous or cyclic loading machine and is placed on its body.

 When mining in a drilling and blasting method, the time required for drilling holes in the face reaches 30–50% of the length of the driving cycle, and the time for fastening is 20–25%. In addition, when loading rock in the face, especially using continuous loaders, the reduction productivity and lengthening the duration of loading is associated with the need for manual cleaning of the rock mass at the walls of the mine. A significant amount of time is spent in the preparation of pits / holes / under the supports of the lining and gutters. These works are carried out mainly by hand.

 The use of shaft drilling rigs for drilling holes and for the erection of lining of suspended mobile roof mounts allows to reduce the duration of these operations. However, the need for a consistent replacement of machines and equipment in the face during the technological process of sinking, as well as the operation of building up the suspended monorail for the mount, lead to the fact that the duration of the sinking cycle practically does not decrease, and the cost of sinking increases.

 During mining using the drilling and blasting method, the use of 1PNB2B and 2PNB2B type boring machines in tunneling complexes and complexes makes it possible to combine loading and drilling mechanisms on a single base. This leads to the fact that in the face decreases the amount of equipment needed to complete the process. At the same time, in such kits and complexes, work on fixing workings is carried out either with the help of suspended mounts or manually using simple devices. Work related to the cleaning of the rock at the walls of the workings and the formation of holes under the supports are always carried out manually. Great difficulties in the creation and use of machinery and equipment for the mechanization of the aforementioned works arise when conducting single-track, relatively small in cross-section and length of mine workings.

 The well-known universal machine "Strek" is intended for the mechanization of installation of mine equipment, the construction of wooden and reinforced concrete prefabricated supports, soil support and loading of rock mass and trolleys, the installation of advanced roof supports / "Machines and equipment for coal mines". Directory. / Ed. Khorina V.N. M: Nedra, 197, p. 300 /. The car "Shtrek" on a wheel-rail. Depending on the type of work performed on the machine, the following can be installed: an excavator or loading bucket, a tick-borne grab of the support elements, a grab, a crane suspension, a device for installing an advanced support.

 A wide range of working equipment makes it possible to carry out various types of work, mainly related to the repair and maintenance of workings. The machine is not very suitable for mining, as when using rail vehicles for the delivery of rock from the face and the delivery of materials to the face in a one-track mine, it impedes the performance of these works. When working directly in the mine face of a mine, distillation of a loading or boring machine is necessary for some distance from the mine face, which is almost impossible when mining relatively small sections / one-track / and leads to clogging of the bottom-hole part of the mine workings of various sections and complicating the organization of work.

The well-known tunnel complex "Siberia" by "Machines and equipment for coal mines." Directory. / Ed. Khorina V.N. M: Nedra, 1987, p. 208, 209. The complex is designed for inclined workings using a drill-and-blast method with a cross section in the light from 12 to 22 m ² . It consists of a platform on a wheel-rail track suspended on a winch rope, two hydraulic loading buckets with side loading built into the platform, a reloader with a hopper, two drilling machines and a fixer. The complex is not self-propelled. The presence in the complex of loading bodies, drilling machines and a crepe installer allows to achieve a high level of mechanization of work. The possibility of using horizontal mining is practically absent. In addition, it can only be used for capital inclined workings of relatively large sections and lengths.

 Known suspension mounters, for example, KPM8 / "Machines and equipment for coal mines." Handbook. / Ed. Khorina V.N. M: Nedra, 197, p. 289,291 /. KPM8 is designed to mechanize the construction of a permanent metal lining and perform advanced safety fastening in preparatory inclined and horizontal mine workings, carried out by drill-blasting and combine methods.

 The disadvantages of suspended mounting supports include the fact that they move along hanging monorails fixed to the upper supports, which must be periodically increased.

 The closest in technical and constructive solution is the "Mine self-propelled manipulator", known for A.S. USSR N 1724883, E 21 D 13/04. This manipulator consists of a lifting boom placed on the frame of the undercarriage with the possibility of rotation in the horizontal plane and longitudinal movement along the frame. A support is mounted at the end of the boom, which is equipped with hydraulic motors that rotate it in the vertical and horizontal planes relative to the longitudinal axis of the boom.

 The manipulator under consideration can be used to perform various operations carried out both during and during the repair of mine workings. At the same time, it should be noted that to carry out certain tunneling and repair operations, special transitional devices are required for placement on its supporting part or a drilling machine, or loading / cleaning / bucket, or installation forks for lining elements, etc.

 The aim of the present invention is to increase the level of mechanization of the main and auxiliary works and labor productivity when conducting a relatively small section of the preparatory workings, by creating a compact mounted movable drill-crepe-stripping module with interchangeable equipment located on the body of the base loading machine. The proposed module allows you to simultaneously perform the main operations of the tunneling cycle: loading the rock with a loading machine and securing the mine, as well as loading the rock with mopping up the rocks at the walls, forming holes for the roof support and conducting a drainage groove. In addition, the proposed module allows drilling holes in the face after the completion of tunneling operations for loading and securing the mine using two drilling machines.

 According to the invention, the goals are achieved in that the brown-crepe-stripping module mounted movably on the body of the base loading machine of continuous or cyclic action, consists of a swept arm mounted on a movable carriage moving along the body of the loading machine; a handle pivotally attached to the end of the boom of the manipulator, drilling machines; a bucket and frames with installation forks for the roof supports with puffs, characterized in that an equal-arm handle is mounted on the end of the boom with the possibility of turning it in two planes by means of two power hydraulic jacks. The hydraulic jacks are pivotally connected at one end to the boom of the manipulator, and the other to the handle by means of cardan joints. At the ends of the handle, depending on the operations performed, either two removable boring machines or a frame with installation forks for the upper arms with puffs, or a bucket for destroying the wall of the dump of the broken rock mass, cleaning the rock near the walls of the excavation, the formation of holes under the supports and gutter grooves.

 The module handle, which is used to place removable ones on it: drilling machines, a bucket and a frame with installation forks, is made telescopically sliding in two opposite directions. This design of the handle allows you to change the distance between the holes and to drill several holes from one position of the manipulator. In addition, when installing the lining, the final compression of the upper parts with puffs to the roof of the excavation is carried out by a sliding jack.

Significant differences are:
1. The drill-crepe-stripping module, which is an arrow-shaped manipulator mounted on a movable carriage moving along the body of the loading machine, has a pivotally mounted equal-armed handle at the end of the boom with the possibility of rotation in two planes by means of two hydraulic jacks attached to it by cardan joints. At the ends of the handle, interchangeable equipment is installed alternately: two drilling machines, a bucket or a frame with installation forks for the roof supports with puffs.

 2. The equal-arm handle is telescopically extendable in two opposite directions, which allows you to change the distance between the drilling machines and increase the reach of the bucket during cleaning, destruction of the slope and the formation of holes for the supports and gutter grooves.

 3. Sliding the handle in two opposite directions is carried out by means of two power hydraulic jacks located inside the handle and pushing its internal parts.

 The invention is illustrated by drawings.

 In FIG. 1 shows a layout diagram of a module 1 located on the body of a continuous loading machine 2. The drill-crepe-cleaning module 1 consists of a boom 3 of the manipulator pivotally mounted on a movable carriage 4, moving along a guide located on the body of the loading machine 2. On the boom 3 of the manipulator, an equal-arm telescoping sliding arm 5 is mounted pivotally, on the sliding ends of which 6 can alternately to be installed: bucket 7 and other equipment. The rotation of the handle 5 relative to the longitudinal axis of the boom 3 is carried out by means of two power hydraulic jacks 8, which are connected to the handle 5 by means of cardan joints 9.

 In FIG. 2 shows the front of the boom 3 of the manipulator, a handle 5, on the sliding end 6 of which a mounting frame 10 with mounting forks 11 is mounted, on which are placed the tops 12 with puffs 13.

 In FIG. 13 shows a layout diagram of module 1 with drilling machines installed on it 14. The handle 5 is rotated around a vertical axis by hydraulic jacks 8 using a flat joint 15.

 In FIG. 4 shows the front of module 1 / view A of FIG. 3 /. At the telescopically extendable ends 6 of the handle 5 are two removable boring machines 14. The initial 1 working position when drilling holes. With an increase in the distance between the boreholes, as well as when drilling further boreholes horizontally at the same position of the boom 3 of the manipulator by means of sliding jacks / in FIG. 4 not shown / extension of ends 6 is carried out - position 11.

 The principle of operation of the proposed module is as follows.

 In the process of unloading the rock mass from the bottom with a loader 2, module 1, on one of the ends 6 of the handle 5 of which a bucket 7 is mounted, carries out raking / cleaning / of the rock remaining at the excavation walls to the loading organ of the machine. With a steady slope of the blade in order to eliminate a possible sharp collapse of the rock mass on the loading table, the stability of the slope / blade wall is destroyed. The formation of pits / holes / under the lining supports and drainage grooves is carried out simultaneously with the unloading of the rock mass from the face.

 After completion of the unloading of the rock from the face or in its last phase, at the second end 6 of the handle 5, a frame 10 with mounting forks 11 is mounted, and the bucket 7 is dismantled. The loading machine 2 is fed back to the storage location of the lining elements. The manipulator of module 1 moves along the body of machine 2 to the rear position and lowers down. On the installation forks are two upper 12 with puffs 13. After that, the loader 2 and module 1 are moved forward. The boom 3 of the manipulator rises and pushes the upper with puffs to the newly formed roof of the mine. The final tightening of the tops to the roof is carried out by a jack with sliding handles. After that, the supports are installed manually under the tops and the elements are connected.

 The next operation of the tunneling cycle is drilling holes. For its implementation, it is necessary to remove the frame 10 from the handle 5. The handle 5 is installed in a horizontal position. After that, when the boom 3 of the manipulator is lowered to the extreme lower position, two boring machines 14 are mounted on the sliding ends 6 of the handle 5 / in our embodiment, these are core electric drills of the EBGP-1 / type. The loader 2 is fed to the face to the required distance and with the help of module 1 the hole is drilled over the entire area.
