Description
技术领域 technical field
本实用新型涉及采矿技术领域，特别涉及一种可更换中板的复合中部槽。 The utility model relates to the technical field of mining, in particular to a composite middle groove with a replaceable middle plate.
背景技术 Background technique
目前国内中部槽的结构型式主要是铸焊式结构，主要由：挡板槽帮、铲板槽帮、中板、底板、齿轨座组件等组成。 At present, the structural type of the middle trough in China is mainly a cast-welded structure, which is mainly composed of: baffle plate trough side, shovel plate trough side, middle plate, bottom plate, rack seat assembly and so on.
由于采煤机采下的煤、矸石等全部落在中部槽上，直接与中板接触，然后随移动的刮板链在中部槽内运行。因此中板所受的摩擦力很大，并且不断循环反复，所以磨损会非常严重。目前国内所用中板只有一层，不可更换，中板磨损后只能靠堆焊来修复。 Because the coal and gangue mined by the shearer all fall on the middle groove, directly contact with the middle plate, and then run in the middle groove with the moving scraper chain. Therefore, the frictional force suffered by the middle plate is very large, and the cycle is repeated, so the wear will be very serious. At present, the middle plate used in China has only one layer, which cannot be replaced. After the middle plate is worn, it can only be repaired by surfacing welding.
另一处磨损严重的地方是铲板，铲板槽帮由铲板与槽帮整体铸造而成。采煤机的滑靴在铲板上往复运用，二者为滑动摩擦。因此铲板磨损严重，目前铲板磨损后也只能靠堆焊修复。 Another place with serious wear is the scraper plate. The scraper plate and the groove side are integrally cast by the scraper plate and the groove side. The sliding shoes of the shearer are used reciprocatingly on the shovel plate, and the two are sliding friction. Therefore the scraper plate wears seriously, and also can only rely on overlay welding to repair after the scraper plate wears out at present.
堆焊虽然可以弥补表面磨损，但堆焊表面质量差，效果很不理想，并且中部槽的强度会降低。而且中部槽数量多，中板面积广，当设备完成一定量的采煤任务需要大修时，大部分中部槽中板和铲板均磨损量过多需要修复，采用大面堆焊费时费力。 Although surfacing welding can make up for surface wear, but the surface quality of surfacing welding is poor, the effect is not ideal, and the strength of the middle groove will be reduced. Moreover, there are many slots in the middle, and the area of the middle plate is large. When the equipment completes a certain amount of coal mining tasks and needs to be overhauled, most of the middle plates and shovel plates in the middle slots wear too much and need to be repaired. It takes time and effort to use large surface surfacing welding.

在铲板槽帮上设置有与铲板相配合的凹槽。 Grooves matched with the shovel are arranged on the groove side of the shovel.
在上中板、铲板上均匀布置有通孔。 Through holes are evenly arranged on the upper middle plate and the shovel plate.
本实用新型的中板由原来整块高强耐磨板，分为普通板和高强耐磨板，即保证了使用效果又大大降低了材料成本；当中板磨损严重需要修复时只需要将上中板取下，更换新的耐磨板重新焊接即可，即降低了维修成本又大大提高了复合中部槽的使用寿命；铲板在原有的铸造槽帮上焊接一块高强耐磨板，减少了采煤机滑靴对铲板的磨损量，大大提高了铲板的使用寿命，并且磨损严重时只需要将铲板用新的更换掉即可。 The middle plate of the utility model is divided into a common plate and a high-strength wear-resistant plate from the original whole high-strength wear-resistant plate, which ensures the use effect and greatly reduces the material cost; when the middle plate wears seriously and needs to be repaired, only the upper and middle plates need to be removed. Next, replace the new wear-resistant plate and re-weld it, which reduces the maintenance cost and greatly improves the service life of the composite middle tank; the shovel plate is welded with a high-strength wear-resistant plate on the original cast tank side, reducing the cost of the shearer. The wear amount of the sliding shoe to the blade greatly improves the service life of the blade, and when the wear is serious, only the blade needs to be replaced with a new one.

具体实施方式 Detailed ways
如图1、图2、图3所示，一种可更换中板的复合中部槽，包括挡板槽帮1、铲板槽帮、中板、底板4，中板的两端分别为挡板槽帮和铲板槽帮，中板由上中板2和下中板3组成，铲板槽帮由铲板6和槽帮5组成，上中板与下中板之间、铲板与槽帮之间均以焊接形式连接。在挡板槽帮和槽帮的中板沿位置设有与中板横截面相配合的缺口7。在铲板槽帮上设置有与铲板相配合的凹槽。在上中板、铲板上均匀布置有通孔8。上中板为高强耐磨板，下中板为普通板，且上中板的厚度小于下中板的厚度。 As shown in Figure 1, Figure 2, and Figure 3, a composite middle tank with a replaceable middle plate includes a baffle plate groove side 1, a scraper plate groove side, a middle plate, and a bottom plate 4, and the two ends of the middle plate are respectively baffle plates The groove side and the scraping board groove side, the middle plate is composed of the upper middle board 2 and the lower middle board 3, the scraping board groove side is composed of the scraping board 6 and the groove side 5, between the upper middle board and the lower middle board, the scraping board and the groove The gangs are connected by welding. A notch 7 matching the cross-section of the middle plate is provided at the edge of the baffle plate and the edge of the middle plate. Grooves matched with the shovel are arranged on the groove side of the shovel. Through holes 8 are evenly arranged on the upper middle plate and the shovel plate. The upper middle plate is a high-strength wear-resistant plate, the lower middle plate is an ordinary plate, and the thickness of the upper middle plate is smaller than that of the lower middle plate.
如果上中板和铲板磨损严重，则可以将上中板与铲板的连接焊缝刨开，换新，避免原来堆焊的表面缺陷、提高效率。铲板与槽帮分体，不再与槽帮一体铸成，可将铲板单独用耐磨材质，增强耐磨性能。上中板和铲板上布置的通孔，如图4中的通孔8所示，能有效防止焊接后中板和铲板产生“鼓肚”等变形，增大焊接面积，强化连接。另外，中板的材质上中板为耐磨材质，下中板为普通板材，上中板薄下中板厚，这样比整个中板均用耐磨材质要节约成本。 If the upper middle plate and the scraping plate are severely worn, the connection weld between the upper middle plate and the scraping plate can be planed and replaced with a new one, so as to avoid the surface defects of the original surfacing welding and improve efficiency. The shovel plate and the side of the groove are separated, instead of being integrally cast with the side of the groove, the shovel plate can be made of wear-resistant material alone to enhance the wear resistance. The through holes arranged on the upper middle plate and the shovel plate, as shown in the through hole 8 in Fig. 4, can effectively prevent the deformation of the middle plate and the shovel plate after welding, such as "bulging", increase the welding area, and strengthen the connection. In addition, the upper and middle plates are made of wear-resistant materials, the lower and middle plates are ordinary plates, the upper and lower plates are thinner and the lower plates are thicker, which saves costs compared to using wear-resistant materials for the entire middle plate.
