单体液¤压支柱为外供恒阻式单体液★压支柱,它可以与各种顶梁配合,也可以作主柱使用。可供炮采工作面支护顶板使用,也可做其他临时性支护使用。
The single hydraulic prop for the external supply of constant resistance type single hydraulic prop, it can be matched with various top beam, can also make use of column. For the blasting mining face supporting the roof, also can do other temporary supporting the use of.
单体液∩压支柱适用于煤层倾角小于25度--35度的倾斜煤层回采工作面,所适应的煤层顶底板条件是:顶板落后不影响支柱的回收,底板㊣ 不宜过软,支柱压入底板深度不恶化底板的完整性,否则应加大底座。
The single hydraulic prop for coal seam dip angle is less than the inclined coal seam mining working face 25 degrees --35 degrees, the adaptation of the coal seam roof and floor conditions is: the roof behind does not affect the pillar recovery, the bottom should not be too soft, integrity pillar pressure into the floor depth is not deteriorated plate should be added, or large base.
在煤质较松软的炮采工作面内使用时,对活柱体镀层表面采取保护措施,以防崩坏。支柱与¤木顶梁配合或做点柱使用时,应将顶盖换成柱↓帽,以免损坏木梁。
Within the mining face in coal more loose cannon, to take measures to protect the active column body surface coating, to prevent the collapse. Pillar and the wooden bar with or do some column when in use, should be changed into the column top hat, so as not to damage the wooden beams.
Pillar according to liquid and liquid, divided into the external supply of liquid type (referred to as the external injection type) and for the liquid type (referred to as the injection type) pillar.
According to different pillar working stroke, divided into single telescopic (Dan Hangcheng) and the double telescopic prop (Shuang Hangcheng) pillar, in does not indicate the travel characteristic, for single telescopic prop.
The pillar by the use of different materials, is divided into ordinary steel pillar, the pillar of high titanium alloy, aluminum alloy, stainless steel pillar pillar, in does not indicate the material characteristics, is a steel pillar.
Pillar can be divided into piston plunger suspension pillar and pillar two categories according to the structure form. Piston type pillar according to the working stroke is divided into single and double telescopic prop expansion. Plunger suspension strut using water medium, which belongs to the "environmentally friendly" pillar.
Because the production batches, the different models, the picture is for reference only

每个规格可替代传统活塞式单体支▓柱2-4个规格,减少了由于工作面采高和巷道受顶板、底板移进量的变化需要换不同型号单体支柱的⊙频次,降低了工人劳动强度和支柱额外备№用数量。
支柱无承载焊缝,同时支柱采用悬浮式技术原理,高压液产生〖的悬浮力直接作用在顶盖端,达到工作阻力的五分之四,立柱受力仅为五分之一,大大提高了支柱支护的稳定性和偏载能力。
由于结构上的改进,避免了因内泄漏造成的支柱虚顶、脱顶情况,支柱一旦泄漏,在井下现场用肉眼直接就能检查出,可随时更换支柱;采用密封补偿和密封涨紧技术原理【,顶板来压越大,密封面配合』越紧密,越不易泄漏。
整体ζ 结构简单,使用寿命长;操作方便,易于维护,能够大大降低支柱升井及维修率。
