Description

The proposed utility model relates to the mining industry, namely to the executive bodies of mining mining machines, and is intended to form a set of trihedral prisms with disk tools that are adaptive to a wide range of operating conditions and increase the efficiency of installation and dismantling works.

Known disk cone (RF Patent 2239059, E21C 35/19, publ. 10/27/2004), consisting of a disk element that is mounted on a trunnion, console mounted in the cone holder with the possibility of free rotation around it and fixed in the axial direction using a combined radially thrust bearing. In this case, the pin is connected to the cone holder with a fixing screw.

The disadvantages of this design are the high complexity of the assembly and disassembly of the bearing assembly, high contact loads on the rolling bearing, leading to intensive wear of the raceways. At the same time, the fixing screw is intended only for assembly and fixing operations, and in cases of jamming of the conical joints of the axle of the disk cone axis with the holder socket, the screw does not provide dismantling operations by using the axial force of the thread. They can be carried out using shock loads, which can damage the thread.

A well-known executive body of a mining combine (A.S. 1456558 USSR, class E21C 27/02, publ. 07.02.89, Bull. No. 5), comprising a cutting disc and a hub with screw loading blades and disk cutters mounted on axes placed in brackets installed behind the screw loading blades. In the brackets, guide grooves are made in which the elastic elements and axes of the disk cones are placed. The elastic elements are made in the form of Belleville springs with guide pins.

The disadvantages of this executive body are the complexity of the design, the decrease of the tool overhang with an increase in the strength of the bottomhole array and the complexity of installation and dismantling operations when replacing the mount in the bottom hole.

Also known is the executive body of a mining combine (A.S. 1280119 USSR, class E21C 25/00, publ. 30.12.86, bull. No. 48), including a hub, a cutting disc with cutters, loading blades, behind which are sequentially mounted brackets with disk cones mounted on them.

The disadvantages of this design are the presence of a two-support disk mounting system and the filling of the labyrinth space between the support brackets.

A common drawback of the analogues described above is the inability to implement a reverse mode of operation of executive bodies.

The closest technical solution to the claimed utility model is the executive body of a roadheader (RF patent No. 2455486, IPC E21C 25/18, E21C 27/24, publ. 10.07.2012, Bull. No. 19), including a boom, a transfer gear and two destructive loading crowns, the axes of which are parallel to the longitudinal axis of the boom. The body of each of the destructive loading crowns is made in the form of a truncated conical surface, or in the form of truncated polyhedral pyramids. On the outer surfaces of the shells of the crushing and loading crowns, trihedral prisms are installed with attachment points for disk tools and axle-axles. A disc tool freely mounted on each axle axle is cantilevered to one of the faces of the trihedral prisms. The fastening part of the pivot axis is located inside the trihedral prism and is rigidly attached with bolts and a lock bar to the partition. On both sides of the disk tool, remote end rings are installed that perform the function of thrust bearings that absorb axial loads during failure.

The disadvantages of this executive body of a roadheader are the limited range of formation of schemes for a set of trihedral prisms with a disk tool according to the parameters of the destruction step, the number of visits of rotary reversible helical spirals, the number of disk tools in one cutting line, the complexity of the design of the attachment points and the complexity of installation and dismantling operations.

The indicated technical result is also achieved by the fact that the U-shaped support is made with an internal U-shaped two-stage stream, one of the steps of which is smaller in width, made in the form of two parallel faces with through lateral rectangular grooves and is associated with a step of a larger width, the opposite side surfaces of which made in the form of symmetrical parallel two gear surfaces.

The executive body of a mining mining machine (Fig. 1-9) consists of a housing 1 of a mining mining machine with feeding mechanisms, a rotary gearbox 2, a hydraulic jack 3 of raising and lowering the reversible working body 4 with a loading shield 5. Reversible working body 4 with a diameter of D _io (Fig. 1) and a width B _p (Fig. 4, 5), forming a loading and conveying space, including a working width B ₃ (Fig. 2, 5) for destruction of the face, includes a hub 6 (Fig. 3) with the housing 7, made in the form of a multifaceted prism. Guides 8 with lateral gear racks 9 are rigidly attached to each face of the housing 7, to which, with a certain step, relative to each other, supports 10 of the U-shaped cut 11 and linear 12 trihedral prisms with trihedral covers 13 are attached (Fig. 2, 4, 5, 7, 9), axes 14 with persistent collars and disk tools 15. Supports 10 of the U-shaped form are attached to the guides 8 using detachable wire locks-clamps made in the form of long cylindrical rods 16 (Fig. 6-9) with folding conical end shanks 17 (Fig. 1, 3, 7, 9) and placed in square through holes (Fig. 6, 8) formed by through lateral rectangular grooves of 18.19 piers 10 U-shaped and gear racks 9.

Moreover, each of the guides 8 with the side gear racks 9 can be made (Fig. 8, 9) two-stage, one of which steps of smaller width is made in the form of flat faces containing through lateral rectangular grooves 19 for long cylindrical rods 16 and is conjugated stage with a greater width, the side surfaces of which are formed as two parallel symmetrical racks 9.

The U-shaped support 10 is made (Fig. 6) with an internal U-shaped brook, one face of which is made flat with a through lateral rectangular groove 18 under a long cylindrical rod 16, and the other opposite face is made with a gear surface 20. In this case, the support 10 A U-shaped can be made (Fig. 8) with an internal U-shaped two-stage brook, one of the steps of which is smaller in width in the form of two parallel faces with through lateral rectangular grooves 18 and is associated with a step of a larger width, pr opposites side surfaces which are in the form of two symmetrical parallel toothed surfaces 20.

The utility model, for example, as the executive body of a mining mining mining machine, is carried out in three stages: preliminary installation, work to destroy the bottomhole array and dismantle in the bottomhole space.

At the stage of preliminary installation (Fig. 3-9) for each working element 4 on the housing 7 in the form of a multifaceted prism, guides 8 with lateral gear racks 9 are rigidly fixed, to which U-shaped supports 10 are attached with a certain step relative to each other gear surfaces 20, providing gear engagement.

Since the housing 1 of a mining mining machine with feed mechanisms moves along the face with a feed speed of V _p and contains two executive bodies, a coal seam is excavated with an average power of m _cf. ≤D _acting The destruction of the bottomhole array is carried out by disk tools 15, and the transportation and loading of the products of destruction to the bottomhole conveyor is carried out by the faces of trihedral prisms 11, 12, regardless of the direction of rotation of the reversing working bodies 4.

At the stage of dismantling in the bottomhole space (Fig. 3-9), the work of the utility model is carried out in the reverse order to the installation work. When dismantling each of the disk tools 15, the trihedral covers 13 are first dismantled, and then the attachment points of the disks 15. When dismantling the attachment points of the trihedral prisms 11, 12 to the guides 8 with side gear rails 9, one of the conical end shanks 17 of the long cylindrical rods is pre-bent 16, removing them for other bent tapered shanks 17 from square through holes (Figs. 6, 8) formed by through lateral rectangular grooves 18, 19 of the U-shaped supports 10 and gear racks 9. After which each th support 10 U-shaped triangular prisms 11, 12, freely withdrawn from engagement with the racks 9 guides 8.
