Dual roller rail clamping type falling-proof scaffold

Abstract

The invention particularly relates to a double-roller clip-rail anti-falling scaffold; a connecting frame is fixedly connected with a brake box; a guide rail is fixedly arranged on one side of the scaffold body; the guide rail is inserted in the brake box; a guide groove is arranged on the lateral wall of the brake box; a brake wheel shaft is arranged in the guide groove; a brake wheel is arranged on the brake wheel shaft; a back pressing wheel is erected on the brake box on the same side where the brake wheel is arranged; the back pressing wheel leans on one side wall body of the guide rail; a friction block is arranged on the other lateral side of the brake wheel; a ratchet wheel is fixed on the end surface of the brake wheel; the lateral wall of the brake box is hinged with a pawl; the bottom of the pawl is supported on the operating end surface of the ratchet wheel; the bottom end of the pawl is connected with a tension spring; the other end of the tension spring is connected on the external wall of the brake wall; the top end of the pawl is connected with a traction rope; the other end of the traction rope is extended out of the brake box and hung with an operating hammer on the end part; a vertical brake tension spring is arranged outside the brake box; the top end of the brake tension spring is fixed and the bottom end is connected on the brake wheel shaft.

Description

technical field [0001] The invention belongs to an attached lifting scaffold used in building construction, and in particular relates to a double roller clamping rail type anti-falling scaffold. Background technique [0002] At present, the fall prevention devices used in many attached lifting scaffolds at home and abroad are relatively complex or simple. The more complicated ones require more parts for processing and assembly, and the assembly and debugging are time-consuming and costly. There are also simple ones in China, but they are not easy to use, and they often do not work at critical times, affecting construction safety and making the safety of construction workers not guaranteed. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a double-roller clamping rail type anti-falling scaffold that can effectively brake the frame body and prevent the frame body from falling when the frame ...
