The invention relates to the technical field of elevator protection, and discloses an engineering construction elevator safety braking device which comprises a traction wheel, rope grooves are axially formed in the outer side of the traction wheel at equal intervals, traction ropes are movably connected into the rope grooves, and sliding grooves are axially formed in the rope grooves in the outer side of the traction wheel at equal angles. The sliding groove is formed in the inner side of the traction wheel in the circumferential direction according to the surface where the rope groove is located, so that the sliding block in the sliding groove is in sealed connection with the sliding groove, and when the sliding groove moves to the upper half portion of the traction wheel, the gravity block in the sliding block moves in the circle center direction of the traction wheel; the gravity block pulls the connecting rope and drives the adjusting block to move towards the interior of the strip-shaped groove, so that the outer side of the adjusting block is not tightly attached to the inner side of the sliding groove, the downward moving speed of the sliding block is increased, the sliding block moves to suck air above the sliding groove, and particles generated after abrasion between the rope groove and the traction rope enter the upper half portion of the sliding groove and are collected.

    本发明涉及电梯保护技术领域,且公开了一种工程建设用电梯安全制动装置,包括曳引轮,所述曳引轮的外侧轴向等距离开设有绳槽,所述绳槽的内部活动连接有曳引绳,所述曳引轮的外侧绳槽轴向等角度开设有滑动槽。通过曳引轮的内侧根据绳槽所在的面周向开设有滑动槽,使滑动槽内部的滑动块与滑动槽之间密封连接,当滑动槽移动到曳引轮的上半部分时,滑动块内的重力块向曳引轮的圆心方向移动,重力块拉动连接绳并带动调节块向条形槽的内部移动,使调节块的外侧与滑动槽的内侧不紧贴,令滑动块向下移动的速度增加,滑动块移动吸入滑动槽上方的空气,使绳槽和曳引绳之间磨损后产生的颗粒进入滑动槽的上半部分,进行收集。
