Description
技术领域technical field
本发明属于煤矿用设备技术领域，尤其涉及一种悬臂式纵轴双截割部掘进机。The invention belongs to the technical field of coal mine equipment, and in particular relates to a cantilever type longitudinal axis double-cutting section roadheader.
背景技术Background technique
近年来随着技术的进步，为了增加产量和经济效益，一些地质条件比较好的煤矿，综采工作面的设备装机功率增大了很多，设备体积也随着相应增大；为了运输和布置大型设备，煤矿煤巷的断面尺寸也相应同步加大；目前很多煤矿煤巷宽度已经达到5m以上，有的接近6m，煤巷断面达到20m2左右，许多已经接近25m2。悬臂式纵轴掘进机是一种投放市场几十年的机型，该机型因具有结构简单、适应性强、技术成熟、生产成本低等优点，具有非常高的市场占有率；为了满足大断面煤巷高效施工的需求，当前悬臂式纵轴掘进机截割电机功率最大已经达到350kw，但到目前为止已有的悬臂式纵轴掘进机,全部都是一个截割部，使用这样的掘进机施工大断面的煤巷，一方面截割速度低，截割用时长，即使增大截割功率，仍然不能完全解决截割速度低、截割用时长的问题，另一方面一次机身定位不能截割全断面，必须采用两次机身定位截割的方法，这也严重影响施工效率，同时两次机身定位，造成每次机身定位截割机身稳定时间相对较短，难以实现使用机载支护设备实施掘锚平行作业施工，不能达到对顶板实施及时支护的目的，而加长截割臂又受到强度的制约。所以目前已有的悬臂式纵轴掘进机，已经不能很好地满足大断面煤巷高效施工的要求，再继续使用这样的机型掘进施工大断面煤巷，必然导致煤矿采掘关系紧张，工作面接续压力大，也影响企业经济效益。In recent years, with the advancement of technology, in order to increase production and economic benefits, in some coal mines with relatively good geological conditions, the installed power of equipment in the fully mechanized mining face has increased a lot, and the volume of equipment has also increased accordingly; in order to transport and arrange large Equipment, and the cross-sectional size of coal mines and coal mines have also increased correspondingly; at present, the width of many coal mines and coal mines has reached more than 5m, and some are close to 6m . The cantilever type longitudinal axis roadheader is a model that has been on the market for decades. This model has a very high market share due to its simple structure, strong adaptability, mature technology, and low production cost; in order to meet the needs of large To meet the needs of efficient construction of cross-section coal roadways, the power of the cutting motor of the current cantilever-type longitudinal-axis roadheading machine has reached a maximum of 350kw, but so far the existing cantilever-type longitudinal-axis roadheaders are all a cutting part. Coal lanes with large sections constructed by machine, on the one hand, the cutting speed is low and the cutting time is long. Even if the cutting power is increased, the problem of low cutting speed and long cutting time cannot be completely solved. The entire section cannot be cut, and the method of positioning and cutting the fuselage twice must be used, which also seriously affects the construction efficiency. The fuselage is positioned twice at the same time, resulting in a relatively short stabilization time for each fuselage positioning and cutting the fuselage, which is difficult to achieve The use of airborne support equipment to carry out parallel operation of digging and anchoring cannot achieve the purpose of timely supporting the roof, and the lengthened cutting arm is restricted by its strength. Therefore, the existing cantilever-type longitudinal-axis roadheaders can no longer meet the requirements of high-efficiency construction of large-section coal roadways. Continuing to use such machines to excavate and construct large-section coal roadways will inevitably lead to tension in the relationship between coal mine excavation. Continued pressure will also affect the economic benefits of enterprises.

为保持悬臂式纵轴双截割部掘进机截割过程的稳定，在机架本体10的左右两侧上分别设有侧向液压支撑稳定装置22，每侧上的侧向液压支撑稳定装置22至少有一个，该侧向液压支撑稳定装置22包括与机架本体10连接的支撑液压油缸，该支撑液压油缸由机架本体10指向巷道侧壁，该支撑液压油缸的接近巷道侧壁的一端上固定设置有一块支撑板，在截割之前将支撑液压油缸的活塞杆伸出，将支撑板紧紧顶靠在巷道侧壁上，在截割过程中，可保持悬臂式纵轴双截割部掘进机机身的稳定，在本实施例中，每侧上的侧向液压支撑稳定装置22设有一个，位于机架本体10的前部一侧。In order to maintain the stability of the cutting process of the cantilever-type longitudinal axis double-cutting section roadheader, lateral hydraulic support and stabilization devices 22 are respectively provided on the left and right sides of the frame body 10, and the lateral hydraulic support and stabilization devices 22 on each side At least one, the lateral hydraulic support and stabilization device 22 includes a support hydraulic cylinder connected to the frame body 10, the support hydraulic cylinder is directed from the frame body 10 to the roadway side wall, and the end of the support hydraulic cylinder close to the roadway side wall A supporting plate is fixedly installed. Before cutting, the piston rod of the supporting hydraulic cylinder is stretched out, and the supporting plate is tightly pressed against the side wall of the roadway. During the cutting process, the cantilevered longitudinal axis double cutting part can be maintained. For the stability of the body of the roadheader, in this embodiment, one lateral hydraulic support stabilization device 22 is provided on each side, which is located on the front side of the frame body 10 .

One end of the adjustment cylinder 26 is connected to the slide rail 25. The other end of the adjustment oil cylinder 26 is connected with the frame body 10; when the cantilever type longitudinal axis double cutting section roadheader stretches out the cutting head to continue cutting, the cut and dropped coal is far away from the loading mechanism 20 , the coal cannot be loaded quickly. At this time, the scraper conveyor 19 and the loading mechanism 20 are pushed forward along the slideway by adjusting the oil cylinder 26, so that the loading mechanism 20 is closer to the cut and fallen coal, and the coal under excavation is avoided. For the problem of being unable to load, after the cutting is completed, the scraper conveyor 19 and the loading mechanism 20 will be retracted along the slideway by adjusting the oil cylinder 26.
