The invention relates to the technical field of lifters, and discloses a safety protection device of a lifter for engineering construction. The problem that gear loads are prone to being damaged due to instant impact when cargoes are loaded and unloaded in a compartment is solved. Comprising a guide rail frame, a rack rail and a plurality of fixing blocks are installed on the guide rail frame, a lift car is arranged on one side of the guide rail frame, the lift car is rotationally connected with a plurality of gear discs, and the gear discs are in meshing transmission with the rack rail; and the two sliding plates are both connected to the lift car in a sliding mode, sliding blocks are connected to the sliding plates in a sliding mode, and the sliding blocks are connected with supporting rods which are in extrusion fit with the adjacent fixing blocks in a sliding mode and used for dispersing acting force acting on the gear disc. Through interaction of the supporting rods and the fixing blocks, instant impact generated by loading and unloading cargos in the lift car is dispersed and acts on the two fixing blocks, the additional load borne by the sliding plate is reduced, the possibility of damage to the sliding plate is reduced, and the use safety of the device is improved.

    本发明涉及升降机技术领域,公开了一种工程施工用升降机安全防护装置。关于车厢上下货物时受到瞬时冲击容易造成齿轮负载损坏的问题。包括:导轨架,所述导轨架上安装有齿轨和多个固定块,所述导轨架的一侧设置有轿厢,所述轿厢转动连接有多个齿轮盘,所述齿轮盘与所述齿轨啮合传动;两个滑动板,均滑动连接于所述轿厢,所述滑动板上滑动连接有滑块,所述滑块滑动连接有与相邻所述固定块挤压配合的支撑杆,用于分散作用在所述齿轮盘处的作用力。本发明通过支撑杆与固定块的相互作用,使轿厢上下货物所瞬时冲击分散作用在两个固定块上,削减了滑动板承受的额外负载,降低了滑动板损坏的可能性,提高本装置使用的安全性。
