The utility model relates to the field of mine construction and installation, in particular to a deformable mine ditch cover plate, which comprises a cover plate frame, a cross beam and a grid plate. A cylindrical sleeve is arranged in the middle and lower parts of the cover plate frame perpendicular to the direction of the length of the cover plate frame, and the cross beam is arranged in the sleeve; the two sides of the grid plate are placed between the damping pads inside the cover plate frame. The space between the cover plate frame and the grid plate provides the deformation space for the ditch cover plate; the sleeve fixes the shield, the lower surface fixes the shield at the bottom end of the beam bottom plate, and the shield and the fixed shield at the lower surface of the bottom end of the beam bottom plate contradict each other to prevent the beam from falling off from the sleeve; On the inner side of the cover plate and the cross beam, the damping pad increases the friction between the cover plate and the grid plate, increases the resistance of the ditch cover plate to lateral extrusion, and reduces the impact noise between the cover plate and the grid plate. The utility model can effectively overcome the defect that the cover plate of the existing mine water ditch does not have coordinated deformation existing in the prior art.
【技术实现步骤摘要】
一种矿用可变形水沟盖板
本技术涉及矿山建设施工安装领域,尤其是一种矿用可变形水沟盖板。
技术介绍
在矿山生产过程中,涌出的地下水通过巷道一侧水沟流入水仓,目前普遍采用的混凝土水沟盖板,由于地压的作用随水沟断面缩小水沟盖板隆起,断裂失去作用,给行走在上面的人员安全带来严重威胁。水沟盖板笨重,损坏后不能再使用需经常跟换,造成人力物力的巨大浪费。金属格栅水沟有一定塑性受挤压变形后可修复,但其边框形状固定挤压后变形开焊现象常发生,经常更换成本太高。
技术实现思路
本技术的目的是克服已有技术的不足之处,提供一种材料方便获得,便于安装使用,可随水沟断面减小协调变形的矿用可变形水沟盖板。为实现上述目的,本技术采用以下技术方案予以实现:一种矿用可变形水沟盖板,包括盖板框、横梁、格栅板;所述盖板框为截面呈ㄈ字形的槽型钢,所述盖板框为左右平行对称设置的2个,且2个所述盖板框的开口相对设置;每个所述盖板框的中下部垂直于所述盖板框长的方向上嵌设固定有若干个左右两端开口的圆柱形套筒,且所述套筒的轴心线与所述盖板框的底板位于同一平面上;所述横梁的截面为倒T字形,且左右对称的2个所述套筒滑动套设所述横 ...
