The invention discloses a vertical ladder for an underground coal mine. The vertical ladder comprises a vertical ladder body used for leaning against a single hydraulic prop, the vertical ladder body comprises side rods at the two sides, and a plurality of transverse rods are arranged between the side rods at the two sides in parallel; an arc-shaped reinforcing plate is arranged at the leaning side of the transverse rod located at the top, the arc-shaped reinforcing plate is an arc-shaped plate, and an arc-shaped opening of the arc-shaped reinforcing plate faces the single hydraulic prop; and the arc-shaped opening is matched with the side face of the single hydraulic prop in shape, and the inner surface of the arc-shaped plate is used for being tightly attached to the side face of the single hydraulic prop. According to the vertical ladder, the arc-shaped reinforcing plate is arranged at the leaning side of the top of the vertical ladder, and the arc-shaped reinforcing plate is buckled to the side face of the single hydraulic prop in the using process, so that the contact face of the vertical ladder and the single hydraulic prop can be enlarged, the stability of the vertical ladder leaning on the single hydraulic prop is improved, and then the construction safety in an underground roadway is improved.
本发明公开了一种煤矿井下用直梯，包括用于倚靠在单体液压支柱上的直梯，直梯包括两侧的侧杆，两侧的侧杆之间平行设置有若干根横杆；位于顶部的横杆的倚靠侧设置有弧形加固板，弧形加固板为弧形板，且其弧形开口朝向单体液压支柱；弧形开口与单体液压支柱的侧面形状吻合，且弧形板的内表面用于紧密贴合在单体液压支柱的侧面上；本发明通过在直梯顶部的倚靠侧设置了弧形加固板，并且在使用时通过弧形加固板卡扣在单体液压支柱的侧面，可以加大直梯与单体液压支柱的接触面，提升直梯倚靠在单体液压支柱上的稳固性，进而提升了井下巷道内施工安全性。
