- the longwall shearer shown in Figs. 1 and 2 is adapted to load seams.
- the longwall shearer 10 may cover seam heights from 63 to 126 inches (1.6 to 3.2 m). Due to the low seam shearer applications, the mainframe 15 of shearer loader 10 has to be quiet compact and, therefore, the assembly and disassembly of some major shearer loader components like, e.g. a haulage motor 100, might be difficult due to the weight and little space available for handling these components.
- haulage motor 100 may have to be assembled to the mainframe 15 of shearer loader 10 underground or has to be removed for maintenance purposes. Handling of such a shearer loader component like the haulage motor 100 by a crane or forklift could be difficult and even impossible.

Description
- The present disclosure refers in general to a shearer loader for underground mining. More particularly, the disclosure refers to a shearer loader comprising a mainframe extending in a longitudinal axis and having a first end portion and a second end portion opposite the first end portion. A ranging arm is swivel-mounted at least at one of the first and second end portions of the mainframe. The ranging arm may be provided with at least one cutting drum pivot-mounted at the ranging arm. At least one shearer loader component is configured to be mounted at the mainframe in a removable manner, for example a haulage motor or an electrical control box.
- Shearer loaders for underground mining are also known as longwall shearers. Such shearers comprise a mainframe with fabricated structure to meet even the toughest mining conditions. During operation of a longwall shearer the mainframe is travelling along rails and the cutting drum rotates to cut the desired mineral, in particular underground coal. The cutting drum rotates about an axis perpendicular to the mine wall and includes vanes extending along the cutting drum. The ranging arm can raise the drum to mine material at different heights.
- A longwall shearer having two cutting drums at different ends of the mainframe is for example shown in
US 7,954,904 B2 ,US 2012/0267940 A1 andAU-B-83820/91 - Due to the tough conditions during operation of longwall shearers large and/or heavy shearer components may have to be replaced. Assembly and removal of such major shearer components from the mainframe of the shearer shall be easy and safe. However, due to the fact that longwall shearers have different sizes, the mainframe and other major components of the shearer have different dimensions. Hence, sometimes the available clearance or free space for removal and assembly of such major components in or from the machine may be very small. The latter is particularly the case if the longwall shearer is a low height machine for low seams. In this case, the remaining clearance in the mainframe for the major components like e.g. a haulage motor is very small. Accordingly, the use of cranes and forklifts to handle the shearer components to be assembled or removed from the mainframe of the shearer could be problematic.
- In one aspect of the present disclosure, a shearer loader for underground mining is disclosed. A shearer loader comprises a mainframe extending in a longitudinal axis and having a first end portion and a second end portion opposite the first end portion. A ranging arm is swivel-mounted at least at one of the first and second end portions of the mainframe. The ranging arm is provided with at least one cutting drum pivot-mounted at the ranging arm. At least one shearer loader component is configured to be mounted at the mainframe in a removable manner. Further, the shearer loader comprises a bearing unit arranged at the mainframe at such a position that the at least one bearing unit supports the at least one shearer loader component when it is moved with respect to the mainframe during assembly or disassembly. Moving of the shearer loader component is necessary if the component has to be mounted to or dismounted from the mainframe, i.e. for example if the component has to be replaced or a maintenance of that component is necessary

The longwall shearer comprises amainframe 15 and two rangingarms arms respective end portions mainframe 15. Both rangingarms cutting drums cutting drum arm arms respective cutting drum seam 50 to be mined. -
Fig. 2 shows a schematic front view of thelongwall shearer 10 ofFig. 1 . As usual, thelongwall shearer 10 runs onrails conveyer 55. Thelongwall shearer 10 is driven by a haulage motor 100 (not shown inFigs. 1 and 2 ) mounted within themainframe 15 and connected to a gear for propellinglongwall shearer 10 on atooth rack 70. Thetooth rack 70 extends along therail 60 ofconveyer 55. - The longwall shearer shown in
Figs. 1 and 2 is adapted to load seams. For example, thelongwall shearer 10 may cover seam heights from 63 to 126 inches (1.6 to 3.2 m). Due to the low seam shearer applications, themainframe 15 ofshearer loader 10 has to be quiet compact and, therefore, the assembly and disassembly of some major shearer loader components like, e.g. ahaulage motor 100, might be difficult due to the weight and little space available for handling these components. - Particularly,
haulage motor 100 may have to be assembled to themainframe 15 ofshearer loader 10 underground or has to be removed for maintenance purposes. Handling of such a shearer loader component like thehaulage motor 100 by a crane or forklift could be difficult and even impossible. - As already mentioned before, the whole
longwall shearer loader 10 moves onrails haulage motor 100, see for exampleFig. 11 . Such ahaulage motor 100 may provide a maximum power rating of 100kW and has an overhaul weight of approximately 500 kg at the minimum. Ahaulage motor 100 configured to be used in a rather smalllongwall shearer loader 10 might have a diameter of at least 400 mm and a length of at least 900 mm. Haulage motors for other longwall shearer larger dimensions might be larger and heavier. - The
haulage motor 100 has to be connected to a gear box located withinmainframe 15, see for exampleFigs. 9 to 12 .Fig. 12 shows a part of themainframe 15 withouthaulage motor 100. Contrary to the view shown inFig. 12 ,Fig. 10 shows a view includinghaulage motor 100 mounted to themainframe 15. - Due to the weight and the dimensions and also due to the small clearance within
mainframe 15, the assembly and disassembly ofhaulage motor 100 might be difficult to be carried out with known handling equipment. - Referring to
Figs. 3-12 , according to the present disclosure abottom portion 105 ofmainframe 15 located in front of a mountingflange 110 for ahaulage motor 100 is provided with one ormore bearing units 115. A fixedsupport flange 120 can be arranged on thebottom portion 105 such that the bearingunits 115 are located betweensupport flange 120 and mountingflange 110, see for exampleFigs. 4-6 andFig. 12 . - A bearing
unit 115 is shown in more details inFigs. 13-16 . Here, abearing unit 115 comprises alower bearing block 125 fixed to thebottom portion 105 ofmainframe 15 by, for example, welding. As shown inFigs. 14 and 15 ,lower bearing block 125 comprises acenter hole 145 and a flatupper face 160. Anupper bearing block 130 comprises a flatlower face 165 and a centeringpin 140. The centeringpin 140 of the upper bearing block 130 fits incenter hole 145 oflower bearing block 125. - In the exemplary embodiment of a
bearing unit 115 shown inFigs. 13-15 fourroller elements 135 are removably arranged onupper bearing block 130. - The principle structure of an exemplary embodiment of
roller element 135 is shown inFig. 16 . Theroller element 135 has ashaft 165 and anupper contact face 150. Alubricated roller 155 or ball is freely rotatable supported within theroller element 135. - Due to the above structure of a
bearing unit 115 the upper bearing blocks can be replaced, if desired. Therollers 155 allow support of a load like, e.g.,haulage motor 100 to be moved thereon in any desired direction parallel to the plane defined byupper bearing block 130. In addition, a load supported by one ormore bearing units 115 may even be rotated around an axis extending parallel to the plane defined by theupper bearing block 130. - As shown in
Figs. 14 and 15 , the upper bearing block 130 can be lifted from thelower bearing block 125. Due to this configuration of an exemplary embodiment of a bearing unit 115 a shim (not shown) may be placed between the two faces 165 and 160 of the upper andlower blocks bearing unit 115 can be adjusted to the component to be supported. - Different
longwall shearers 10 have different dimensions and, most likely, the haulage motors to be used therein have different dimensions, too. If the bearingunits 115 shall be used in all kind oflongwall shearers 10, the support height for thehaulage motor 100 might be different. - Due to use of at least one shim to be placed between a lower bearing block and an upper bearing block, the same kind of bearing units can be used in different longwall shearers even if the respective haulage motors have different sizes. Of course, the same applies to other shearer loader components to be moved with respect to the frame during assembly or disassembly.
- A mainframe according to the present disclosure may not only protect all the modular shearer loader components but also enables selective overhaul and modular unit exchange for the most efficient maintenance in the industry.
-
Longwall shearers 10 disclosed herein are configured for underground mining. Formaintenance haulage motor 100 may be removed from themainframe 15 of thelongwall shearer 10 and later be assembled again. - Referring now to
Figs. 3 to 5 ,7 and 8 , the mounting process is explained in more details. As shown inFig. 3 ,haulage motor 100 can be placed onsupport flange 120 by means of known equipment (not shown). Supported bysupport flange 120 the haulage motor is pushed horizontally in the direction to a mountingflange 110.Haulage motor 100 has finally be mounted to mountingflange 110 during operation of thelongwall shearer 10. - Due to the arrangement of one or
more bearing units 115 betweensupport flange 120 and mountingflange 110,haulage motor 100 is supported across the whole distance to the mountingflange 110. Hence, it might not be necessary to use forklifts or similar devices for moving thehaulage motor 100 up to mountingflange 110. As the bearingunits 115 have forexample roller elements 155, the forces necessary for pushinghaulage motor 100 to mountingflange 110 are relatively low and a worker might easily handle the transport, although the clearance in the mainframe is very small. - The
roller elements 155 allow movement of a load in all directions. Therefore, it might be very easy for a worker to rotatehaulage motor 100 already pushed to the correct mounting position in the correct mounting orientation. Whenhaulage motor 100 is correctly oriented, haulage motor can easily mounted to mountingflange 110 by for example bolts (not shown). That handling might be very difficult with support by means of common devices in the small clearance provided in the mainframe. - Although the preferred embodiments of this invention have been described herein, improvements and modifications may be incorporated without departing from the scope of the following claims.
