The invention relates to a self-locking anti-falling device for a construction elevator. The self-locking anti-falling device for the construction elevator effectively solves the problem that a construction elevator emergency braking device is easy to fail and the braking force of the construction elevator emergency braking device is limited. The technical scheme includes the steps that the self-locking anti-falling device for the construction elevator comprises a guiding rail frame and an elevator car; the front side of the guiding rail frame is fixed to a vertical column with a rectangular cross section; the rear wall of the elevator car is fixed to a rectangle sleeve; the vertical column is sleeved by the rectangle sleeve and the rectangle sleeve is matched with the space of the vertical column; the inner wall of the rear side of the elevator car is provided with a fixing block; a vertical chamber with a rectangular section is formed inside the fixing block; the top surface of the chamber is a slope with the left side higher than the right side; the interior of the chamber is provided with a deflectable rectangle block which can move up and down; the rectangle block is fixedly connected with the rectangle sleeve through a horizontal connecting rod; when the elevator car is weightless, the slope on the top of the chamber enables the rectangle block to drive the rectangle sleeve to deflect, so as to lock the rectangle sleeve to the vertical column, and the elevator car is stopped; and the self-locking anti-falling device for the construction elevator can realize self-locking when the elevator falls, can effectively brake the elevator car and work reliably.

    本发明涉及一种自锁式建筑施工电梯防坠装置,有效的解决了施工电梯紧急制动装置容易失灵、制动力有限的问题;解决的技术方案包括导轨架和电梯厢,导轨架的前侧固定有一个截面为矩形的竖向的立柱,电梯厢后壁上固定有一个矩形套,矩形套套设在立柱上且与立柱间隙配合,电梯厢的后侧内壁上设有一个固定块,固定块内开有一个竖向的截面为矩形的腔体,腔体的顶面为左高右低的斜面,腔体内安装有一个可上下移动且可偏转的矩形块,矩形块经一个横向的连杆与矩形套固定连接,电梯厢失重时腔体的顶部斜面可使矩形块带动矩形套偏转从而将矩形套锁死在立柱上,对电梯厢进行制动;本发明在电梯坠落时能实现自锁,能够对电梯厢有效制动,工作可靠。
