行人天井梯子间钢制结构
摘要：
本实用新型公开了一种行人天井钢制梯子间，涉及矿山安全设备技术领域；它包括有安装在天井的井壁上的梯子平台与放置在梯子平台上的钢制梯子，所述梯子平台由锚杆、垫板、横梁以及钢轨组成，所述锚杆的一端插入井壁内，垫板焊接在所述锚杆的另一端上，所述横梁焊接于上述的垫板上，所述钢轨平铺在所述横梁上并予以固定，该钢轨上还留有用于放置钢制梯子的梯子口；本实用新型的有益效果是：本实用新型的整体结构强度，格筛型结构形式有利于降低爆破冲击波的破坏力，修复维护量极少；并且其材料耐腐蚀，安全性好，使用寿命长，性价比高；另外，本实用新型采用在矿山生产过程中大量淘汰的废旧钢轨或强度满足要求的管材为主要材料，极大降低成本。
摘要（英）：

The utility model discloses a steel ladder compartment for a pedestrian courtyard, and relates to the technical field of a mine safety appliance. The steel ladder compartment comprises a ladder platform and a steel ladder, wherein the ladder platform is arranged on the wall of the courtyard; the steel ladder is arranged on the ladder platform; the ladder platform is composed of an anchor rod, a base plate, a beam and a steel rail; one end of the anchor rod is inserted into the wall; the base plate is welded at the other end of the anchor rod; the beam is welded on the base plate; the steel rail is paved and fixed on the beam; a ladder opening for placing the steel ladder is also reserved in the steel rail. The steel ladder compartment has the beneficial effects that reduction of destructive power of an impact wave is facilitated by the overall structure strength of the steel ladder compartment in a form of a grating structure, the steel ladder compartment is less in repair maintenance, and the material is corrosion resistant, good in safety, long in service life, and high in cost performance. In addition, a lot of eliminated rail scraps in the mine production process or tubular products of which the strength meets the requirements are adopted as main materials, so that the cost is greatly reduced.
