Abstract

The invention concerns the construction of a mechanism for connecting a roadheader with a feeder, especially useful when excavating underground excavations with a roadheader in soft-floor conditions. The body (6) of the roadheader (2) has an articulated handle (8), constituting one element, equipped with an upper handle (8a) and a lower handle (8b). The feeder (5) is equipped with an articulating handle (7), preferably in the form of a spatial joint.

Description of the invention

The subject of the invention is a mechanism for connecting a roadheader with a feeder, used in excavating workings in underground mining.

In the known systems of haulage of the excavated material in a hollow roadway with the use of a long-range roadheader, the material from the roadheader loader is fed to the feeder located behind the roadheader, and from the feeder it is directed to the haulage conveyors. The feeder is coupled in movement with the roadheader body and can move along the pavement floor, as for example known from the Polish patent description No. 157 271, or be suspended on the rails of a suspended monorail, as for example known from the Russian patent RU 2 209 311 C1, or from the Polish patent application P-318854. The feeder can also move along the route of the hauling conveyor, as is the case, for example, in the solution according to Polish patent description No. 167 816.

Technical problems of cooperation between the feeder and a roadheader appear in a situation of rapidly changing position of the roadheader body. Then, the articulated handle, in which the feeder is connected to the roadheader, is subject to loads of different direction and level, which lead to blocking or damage to this connection. Such situations can be eliminated to a certain extent by the proper construction of the catch, for example a double-hinged catch, known from the Polish description of the utility model Ru 58976. However, with significant differences in the level of work of a roadheader and a feeder, which usually takes place when running a road in conditions of soft floor rocks, the scope the free movement carried by such a hitch is nevertheless too small to meet the needs. Therefore, there are fundamental problems with the transfer of the output from the loader of the roadheader to the feeder, and also with the spreading of the output from the loader or feeder onto the pavement floor. The presented inconveniences significantly disorganize the work of drilling the pavement, causing frequent repetition of mechanical failures that are difficult to remove due to the binding prohibitions on conducting welding works in underground workings of hard coal mines.

The aim of the invention is to develop such a structure of the mechanism of connecting the roadheader with the feeder, which to a large extent eliminates the currently existing disadvantages.

The essence of the invention consists in the fact that the articulated holder of the feeder is connected to the articulated holder of the roadheader body by means of a rigid connector cooperating with a support acting on this connector pivotally in the vertical plane defined by the longitudinal axis of the connector.

Preferably, the link is in the form of a beam mounted at one end in the joint holder of the roadheader body, and at the other end mounted in the joint holder of the feeder.

It is best when the pivoting handle of the dispenser is a spatial articulated handle, which substantially increases the freedom of movement of the connector end fixed in it.

In a preferred embodiment, the support is in the form of a hydraulic actuator and is fixed with one end in the connector holder, located on the side of the feeder, and the other end is mounted in the articulated holder, attached to the roadheader body below the articulated holder that fastens the connector, thanks to which the end of the connector cooperating with the feeder can be lowered or lifted with sufficient force.

It is simple to make the articulated handle of the roadheader in such a way that it has the form of one element containing on the top a bolt handle fastening the fastener, and on the bottom, below, it has a second pin handle fastening one end of the support.

The main advantage of the mechanism according to the invention is the possibility of changing the position of the loading spout of the feeder in relation to the body of a roadheader with a very large range, with the possibility of a very simple and quick change of this position. It is very useful in the working conditions of a roadheader on a soft floor, when the roadheader sinks into the floor rocks with its undercarriage and it is necessary to change the position of the feeder in relation to the discharge end of the roadheader's loader, as well as to obtain an appropriate slope of the feeder's route, eliminating the fall of the collected spoil from it. . The very structure of the mechanism according to the invention is very simple to manufacture and operate.

The invention is explained in more detail in the drawing, which shows the connection mechanism according to the invention in a side view.

PL 214 403 B1

The excavated material 1 obtained by the roadheader 2 from the cutting of the roadheader 3 is fed from the loader 4 of the roadheader 2 to the loading end of the feeder 5, which overlaps the dump of the loader 4. The feeder 5 and the body 6 of the roadheader 2 are connected in this way, that the articulated holder 7 located in the end of the feeder 5 is coupled to the articulated holder 8 of the roadheader's body 6 by means of a rigid beam 9. The articulated holder 7 has the form of a spatial joint. The beam 9 has a holder 10 in which one end of the hydraulic cylinder 11 is articulated by means of a pin, which serves to pivot the beam 9 in a vertical plane. The other end of the hydraulic cylinder 11 is connected by a pin to the articulated holder 8 of the roadheader's body 6 2. The articulated holder 8 is made as one element with two holders 8a, 8b, one of which 8a is used to fix the beam 9, and the other, below the handle 8b located is used to fix the other end of the hydraulic cylinder 11.
