技术领域technical field
本发明涉及一种充填液压支架，尤其涉及一种适用于对工作面采空区进行充填的带有自动翻袋机构的液压支架。The invention relates to a filling hydraulic support, in particular to a hydraulic support with an automatic bag turning mechanism suitable for filling goafs in working faces.
背景技术Background technique
液压支架是综合机械化采煤的关键设备，几乎在各个煤矿的矿井中都需要用到。目前常见的液压支架是为通常的工作面采掘设计的，其后部支撑空间较小，不能针对一些随采随冒的破碎顶板实行大步距掩护功能，更重要的是，当需要充填采空区时，装有充填材料的料袋必须从狭窄的支撑空间中运输至需要充填的地点，并通过人工手动翻袋使其落入采空区，这种充填方式不但费时费力，还容易发生危险，极大的影响了煤矿的安全生产。Hydraulic support is the key equipment for comprehensive mechanized coal mining, and it is used in almost every coal mine. At present, the common hydraulic support is designed for normal working face mining, and its rear support space is small, so it cannot perform the function of large-step protection for some broken roofs that occur at any time. More importantly, when it is necessary to fill the goaf In the mined-out area, the bag containing the filling material must be transported from the narrow support space to the place where it needs to be filled, and the bag must be manually turned over to make it fall into the goaf. This filling method is not only time-consuming and labor-intensive, but also prone to danger. , which has greatly affected the safe production of coal mines.
发明内容Contents of the invention
本发明针对现有技术中的缺陷，提供一种具有大步距掩护、自动翻袋充填采空区的液压支架。该液压支架不仅能够保证采煤时具有足够的支护强度，而且在该支架的尾部可形成超大距离的支撑空间，以掩护后部的具有弹射翻袋功能的刮板输送机，把刮板输送机输送过来的成袋的煤矸石等充填材料翻转到采空区中，达到充填采空区的目的。Aiming at the defects in the prior art, the present invention provides a hydraulic support with large step distance cover and automatic bag turning to fill the goaf. The hydraulic support can not only ensure sufficient support strength during coal mining, but also form a large-distance support space at the tail of the support to cover the rear scraper conveyor with the function of ejecting and flipping bags, and transport the scraper The bagged coal gangue and other filling materials transported by the machine are turned over into the goaf to achieve the purpose of filling the goaf.
本发明的技术方案如下：Technical scheme of the present invention is as follows:
一种具有自动翻袋机构的充填液压支架，包括立柱、顶梁和底座，所述立柱固定连接所述顶梁和所述底座，所述顶梁的后端铰接后掩护挡板的一端，所述后掩护挡板的另一端为自由端，所述后掩护挡板可在后液压油缸的驱动下绕其与所述顶梁的铰接点转动，所述底座上设置有横向布置的后输送机千斤顶，所述底座的后端连接有后挡板座，所述输送机千斤顶和所述后挡板座之间设置有溜槽，所述溜槽的底板上设置有液压千斤顶，所述溜槽中设置有刮板，所述刮板可相对溜槽移动。A filling hydraulic support with an automatic bag turning mechanism, including a column, a top beam and a base, the column is fixedly connected to the top beam and the base, the rear end of the top beam is hinged to one end of the rear shielding baffle, the The other end of the rear shielding baffle is a free end, and the rear shielding baffle can rotate around its hinge point with the top beam under the drive of the rear hydraulic cylinder, and the rear conveyor arranged horizontally is arranged on the base Jack, the rear end of the base is connected with a tailgate seat, a chute is arranged between the conveyor jack and the tailgate seat, a hydraulic jack is arranged on the bottom plate of the chute, and a The scraper is movable relative to the chute.
所述刮板上设置有刮板圆孔。A scraper circular hole is arranged on the scraper.
所述液压千斤顶设置在所述溜槽的偏支架方向的部分中The hydraulic jack is arranged in the part of the chute in the direction of the support
所述液压千斤顶通过高压油管与所述充填液压支架上的电磁阀连接。The hydraulic jack is connected with the solenoid valve on the filling hydraulic support through a high-pressure oil pipe.
本发明的有益效果是：在能够保证液压支架稳定性的条件下，满足采空区充填自动翻袋的需要。本发明所述的液压支架在采煤时，较长的后掩护挡板在液压缸的作用下伸出与顶梁位于同一水平面上，主动支护充填区破碎顶板，同时对液压支架后方的刮板输送机起到很好保护作用。The beneficial effect of the invention is: under the condition that the stability of the hydraulic support can be ensured, the requirement of automatic bag turning for goaf filling can be met. When the hydraulic support according to the present invention is mining coal, the longer rear shielding baffle protrudes under the action of the hydraulic cylinder and is located on the same level as the top beam, actively supports the broken roof in the filling area, and at the same time scrapes the rear of the hydraulic support. The plate conveyor plays a very good protective role.
