Description

Technology area

The technical solution relates to mining engineering and is used in tunneling machines for mining workings by a combine method with the installation of anchor support.

State of the art

From the prior art, it is known that a mining machine with an anchor fitter is taken as the closest analogue, which includes a frame to which an actuator is attached along the longitudinal axis of the machine, and undercarriages are attached to the left and right, at least one drilling and anchoring device, a transverse beam, connected with it manipulators made in the form of articulated parallelograms with a drive, in which one side is fixed motionlessly, a rotary-gripping device, which is kinematically connected with the drilling and anchoring device, a shaft installed along the longitudinal axis of the machine, connected to a transverse beam, characterized in that articulated parallelograms are attached outside the machine, one at a time to each undercarriage and are located in planes parallel to the longitudinal axis of the machine, while the fixed side of each articulated parallelogram is the stationary part of the corresponding undercarriage, to which at least two rocker arms, kinematically connected by a connecting rod, while the connecting rods of the articulated parallelograms of the bogies are connected to each other by a transverse beam, on which a telescopic shaft is installed, with the possibility of sliding along the longitudinal axis of the machine and the ability to move along the transverse beam, and the rotary-gripping device is installed on it the end from the side of the face with the possibility of rotation, a kinematically connected device for drilling and anchoring in a plane perpendicular to the longitudinal axis of the machine, and inclination relative to this plane towards and away from the face [1].

The disadvantage of this design is that the length at which it is possible to feed the drilling and anchoring device installed on the telescopic shaft of the transverse beam into the working area is directly related to the length of the rocker arms of the articulated parallelograms of the bogies: the longer the rocker arm, the closer the device can be fed to the bottom. drilling and anchoring. But at the moment of folding / unfolding of the anchor-setting structure, the rocker arms of the articulated parallelograms pass a vertical position in the mine workings, while the connecting rods of the articulated parallelograms with a transverse beam, on which the telescopic shaft with a drilling and anchoring device is installed, must fit into this height of the mine workings. Therefore, this design of manipulators is applicable in workings with a large cross-section, and is not suitable for workings with a small cross-section.

Task

To create a construction of a tunneling machine with an anchor-installer, which will allow it to fit in height into mine workings of a smaller section, and, accordingly, a lower height, and will retain the possibility of delivering the drilling and anchoring device to any point along the perimeter of the working, as well as to the face of the face.

As a result of solving this problem, a technical result will be obtained, which consists in creating a more flexible mechanism for delivering the drilling and anchoring device to the working area in front of the executive body of the tunneling machine, which at the time of folding / unfolding of the anchor-setting structure will allow it to fit into the given height "H" of the mine working.

Achievement of the claimed technical result will provide the technical solution with consumer properties - the expansion of a number of typical sections of mine workings, in which it is possible to use the claimed tunneling machine with an anchor installer, including a smaller section.

Disclosure of a technical solution

In the already known from the prior art a mining machine with an anchor installer, which includes a frame (1), to which an actuator (7) is attached along the longitudinal axis (X) of the machine, and the undercarriages (2) are connected to the left and right, a transverse beam (4) with a telescopic shaft (8) installed with the possibility of sliding along the longitudinal axis (X) of the machine and the ability to move along the transverse beam (4), manipulators (10) connected to the transverse beam (4), installed in planes (V) parallel to the longitudinal axis (X) machines, each of which includes a driven articulated parallelogram (3), mounted outside the corresponding undercarriage (2), the rocker arms (ZA and Ze) of which one of the ends is fixed to the latter, and the opposite ends are connected to the connecting rod (3b), installed at the end of the telescopic shaft (8) from the side of the face (9) a rotary-gripping device (5) with the ability to rotate around the axis (Y) of the telescopic shaft (8) and a device kinematically connected to it drilling and anchoring (6), in accordance with the invention it is proposed to additionally introduce an upper articulated parallelogram (11) into the design of each manipulator (10), the connecting rod (11a) of which is fixed on the transverse beam (4), and the rocker arms (11b and 11c) are kinematically connected with the connecting rod (3b) of the drive articulated parallelogram (3) with the possibility of plane-parallel movement of both connecting rods (11a and 3b), while, in one of the rocker arms (lib) of the upper articulated parallelogram (11), perform an additional hinge assembly coupled with the rod ( 12), kinematically connected with one of the rocker arms (3a) of the driven articulated parallelogram (3).

In addition, it is proposed:

- to provide the drive articulated parallelogram (3) with a drive in the form of a hydraulic jack (3c), which is pivotally connected to the frame (1) and at least one rocker arm (3a) of the driven articulated parallelogram (3);

- the rocker arms (3a) of the driven articulated parallelogram (3) should be installed outside the corresponding undercarriage (2) on axles, one of which is designed as an extension of the axis (2a) of the driven wheel (2b) of the undercarriage (2), and the second axle (2c) is additionally introduced into the design of the undercarriage (2);

- fasten the telescopic shaft (8) from the bottom of the transverse beam (4) with the possibility of movement along it with a drive made in the form of a hydraulic jack (4a);

- the thrust (12) is made in the form of a rigid lever;

- make the thrust in the form of a hydraulic jack (12a).

The causal relationship between the technical result and the newly introduced essential features is explained as follows. The introduction of an additional upper articulated parallelogram into the design of each manipulator, the movement of which is transmitted through the thrust from the drive articulated parallelogram already in the design, makes the manipulator more flexible than its closest analogue. A pair of hinged rocker arms, during the delivery of the drilling and anchoring device forward to the bottom and back, are almost constantly in the position of a broken line, and the moment they line up in a straight line, which is their greatest total length, they are at an angle to the vertical axis mine workings, which allows you to fit in height "H" into mine workings of a smaller section. As a result, the inventive design with an additional parallelogram makes it possible to deliver the drilling and anchoring device forward even closer to the bottom. allows to lengthen the rocker arms of the upper articulated parallelogram within the framework of fitting into the given height "H" of the mine working. Achievement of the claimed technical result gives the invention consumer properties - the expansion of a number of typical sections of mine workings, in which it is possible to use the claimed mining machine with an anchor installer, including a smaller section.

Industrial applicability

The implementation of the technical solution is shown in examples (Fig. 1-6), which are not exclusive, but clearly demonstrate the possibility of achieving the claimed technical result.

A mining machine with an anchor-installer includes a frame (1), to which an executive body (7) is attached along the longitudinal axis (X), and bogies (2) are attached to the left and right. Manipulators (10) are connected to the undercarriage (2) from the outside of the machine in planes (V) parallel to the longitudinal axis (X) of the machine, each of which includes a drive articulated parallelogram (3) with a drive (3c) made in the form of a hydraulic jack, which is pivotally connected to the frame (1) and at least one of the rocker arms (3a) (Fig. 1, 2, 3).

The stationary part of the corresponding undercarriage (2) of the mining machine is used as the stationary base of each driven articulated parallelogram (3). As an example, the stationary part is made in the form of an axle (2a) protruding outward by the amount (L) of its driven wheel (2b), on which one of the rocker arms (3a) is hinged (Fig. 4). The second rocker arm (3e) is installed on an axle (2c) additionally introduced into the structure, fixed outside the corresponding running carriage of the mining machine (Fig. 5). Both rocker arms (3a and 3e) are kinematically connected by a connecting rod (3b), forming a driving articulated parallelogram (3) (Figs. 1, 2).

To achieve the claimed technical result, an upper articulated parallelogram (11) is additionally introduced into the design of each manipulator (10). The connecting rods (11a) of the upper articulated parallelograms (11) are fixed on the cross beam (4) from both sides of the machine, and a pair of rocker arms (11b and 11c) of each upper articulated parallelogram (11) are kinematically connected to the connecting rod (3b) of the corresponding driving articulated parallelogram (3 ) with the possibility of plane-parallel movement of both connecting rods (11a and 3b) of the drive (3) and upper (11) articulated parallelograms.

On each side of the mining machine, to one of the rocker arms (11b) of the upper articulated parallelogram (11), a rod (12) is pivotally connected, kinematically connected by the opposite end to one of the rocker arms (3a) of the driven articulated parallelogram (3), which provides plane-parallel movement of the connecting rod (11a) ) of the upper articulated parallelogram (11), fixed on the transverse beam (4), on which a telescopic shaft (8) is installed with a rotary-gripping device (5) at the bottom-side end (9), which is equipped with a drilling and anchoring device (6) ... The telescopic shaft (8) in the example is fixed to the bottom of the transverse beam (4) with the ability to move along it, i.e. across the working, the drive is, for example, a hydraulic jack (4a) (Fig. 3). The rotary-gripping device (5) provides rotation about the axis of the telescopic shaft (8) of the kinematically connected drilling and anchoring device (6), providing a range of work both in the sides of the mine and in the face (9).

FIG. 6 shows a possible version of the thrust (12a) in the form of a hydraulic jack, which is fixed with one eyelet on one of the rocker arms (3e) of the driving articulated parallelogram (3), and the rod eyelet is pivotally connected to one of the rocker arms (11b) of the upper articulated parallelogram (11).

The mining machine works with the bolter as follows. Before feeding the drilling and anchoring device (6) to the working zone, the mining machine is stopped to extract the rock mass, and the executive body (7) is lowered onto the mine workings along the longitudinal axis (X) of the mining machine.

Then, the drives (3c) are turned on in the form of hydraulic jacks on the sides of the mining machine, each of which is pivotally connected with one end to the frame (1), and the opposite end is connected to the rocker arm (3a) of the driven articulated parallelogram (3). The rod (3d) of the hydraulic jack is extended, which begins to turn the corresponding rocker arm (3a) (Figs. 1, 2). During the movement of the rocker arm (3a) of the driven articulated parallelogram (3), the rod (12) kinematically connected to it transfers the force to the upper articulated parallelogram (11) and provides a plane-parallel movement of the connecting rod (11a) of the upper articulated parallelogram (11). Since the connecting rods (11a) located on both sides of the mining machine are structurally interconnected with a transverse beam, they are set in motion and fed towards the face (9) a rotary-gripping device (5) mounted on the transverse beam (4) with a device drilling and anchoring (6). If necessary, additional feed towards the bottom (9) is also carried out by extending the telescopic shaft (8). Adjustment of the position of the drilling and anchoring device (6) along the working width is carried out by moving the rotary-gripping device (5) along the transverse beam (4) with a hydraulic jack (4a). Thus, the required position of the drilling and anchoring device (6) in front of the executive body (7) is provided in a complex manner. Further, by rotating and tilting about the axis (Y) the rotary-gripping device (5) with the drilling and anchoring device (6), the drilling and anchoring device (6) is installed in the required position, and in the process of operation, it is moved along the working section to the desired points, providing drilling and anchoring to any point along the perimeter of the mine and into the face (9).

The inventive tunneling machine with an anchor installer can be manufactured by known means using modern technologies, therefore the technical solution is industrially applicable and provides the claimed technical result.
