Description
带夯实机构的填充支护液压支架 技术领域 Filling support hydraulic support with tamping mechanism
本实用新型涉及一种用于煤矿井下采煤工作面的支护设备， 具体说是一种 在采煤工作面的采空区进行填充、 支护作业的液压支架。 The utility model relates to a supporting device used for coal mining face under coal mine, in particular to a hydraulic support for filling and supporting work in a goaf of a coal mining face.
背景技术 Background technique
我国煤炭资源丰富，综采设备成熟，采煤工艺日趋完善， 随着能源的紧缺， 我国煤炭开采步伐的日益加快， 很多矿井面临着资源枯竭问题， 而一些蕴藏在 建筑物、 道路以及水体下面被认为不宜于开采的煤层， 也越来越受到更多的关 注。 国内一般通过采用条带开采、 搬迁村庄、 充填开采等多种技术措施来解决 "三下"的压煤问题， 提高煤炭采出率。 但是随着村庄搬迁成本的不断提高以 及煤层开采深度的增加， 充填开采技术的优势明显体现出来， 并已逐渐形成蓬 勃发展之势。 现有的充填技术大多采用注水、 注泥浆及填充矸石等方法来充填 采空区。 注水和注泥浆都要受到当地具体地质条件的限制， 在中原地区， 填石 法的采用比较普遍， 其缺点是在进行填充时除了需要支护设备外， 还需提供专 门的运输设备以及夯实机械， 因此投资很大、 作业程序比较复杂。 China's coal resources are abundant, the comprehensive mining equipment is mature, and the coal mining technology is becoming more and more perfect. With the shortage of energy, the pace of coal mining in China is accelerating, many mines are facing the problem of resource depletion, and some are hidden under buildings, roads and water bodies. Coal seams that are considered unsuitable for mining are also receiving more and more attention. In China, the use of strip mining, relocation of villages, filling and mining and other technical measures to solve the "three down" coal crushing problem and increase the coal mining rate. However, with the continuous improvement of village relocation costs and the increase of coal seam mining depth, the advantages of filling mining technology are clearly reflected, and it has gradually formed a booming trend. Most of the existing filling techniques use water injection, mud injection and filling of meteorites to fill the goaf. Water injection and mud injection are subject to the specific geological conditions in the local area. In the Central Plains, the use of rockfill method is more common. The disadvantage is that in addition to the maintenance equipment, special transportation equipment and compaction machinery are required. Therefore, the investment is large and the operating procedures are complicated.

The role. The hinges of the base 16 and the front and rear links 9 and 10 are hinged in a single shaft. In addition, in the connection position of the top beam 3 and the base 16 and the four upper and lower ends of the four columns 19, column holes are respectively provided to facilitate the movement of the hinge.
除了上述方案之外， 也可以不设置挡护装置； 或将挡护装置中的挡矸座仅 设置成一个挡护立板， 夯实机构可铰接在立板上、 或直接铰接在底座上。 还可 不设置夯实机构； 或将夯实机构中的摆梁和夯矸梁设置成固定一体的、 或设置 为多根分别带液压千斤顶的独立结构。另外，还可以将上连杆设置为 H型结构、 或位于左右两侧的 I型独立结构， 这时前、 后连杆可设置为左右对称的两组， 每组的上端分别与上连杆一侧的下部相铰接， 每组的下端分别与立柱之间的底 座两侧相铰接， 同样可实现方便观察采空区填充夯实情况的目的。 此外， 在保 证四连杆机构具有足够支撑力的情况下， 也可将立柱只设置为左右对称的两 根。 还可以将托板设置为直接固定在尾梁上。 In addition to the above, the retaining device may not be provided; or the retaining seat in the retaining device may be provided only as a retaining plate, and the compacting mechanism may be hinged to the vertical plate or directly hinged to the base. It is also possible not to provide a tamping mechanism; or to set the sway beam and sill beam in the tamping mechanism to be one-piece, or to be provided as a plurality of separate structures with hydraulic jacks. In addition, the upper link can also be set as an H-shaped structure, or an I-type independent structure located on the left and right sides. At this time, the front and rear links can be set to two groups of left and right symmetry, and the upper ends of each group are respectively connected with the upper link. The lower part of one side is hinged, and the lower end of each group is respectively hinged with the two sides of the base between the columns, so that the purpose of observing the filling condition of the goaf can be realized conveniently. In addition, in the case where the four-bar linkage mechanism is provided with sufficient supporting force, the column can be set only to two symmetrical sides. It is also possible to set the pallet to be directly attached to the tail boom.
