Kinetic-energy-free falling-preventing safety lock for scaffold

Abstract

The invention discloses a kinetic-energy-free falling-preventing safety lock for a scaffold, comprising a lock bracket and a lock body, wherein the lock body is rotatably connected with the lock bracket through a mounting shaft; the lock bracket is provided with a stopping block; a balancing weight is arranged at the lower part of the lock body; the lock body is provided with outwards protruding pusher dogs and tapered ends; after the lock body rotates, the pusher dog can support against the stopping block; the lock bracket is also fixedly connected with a tilt-preventing support with four guide wheels; the lock body comprises two locking pieces made into a whole and the balancing weight arranged between the two locking pieces; and the two locking pieces are provided with the outwards protruding pusher dogs and the tapered ends. The kinetic-energy-free falling-preventing safety lock for the scaffold is simple in structure, convenient to mount and use, is free of operation of operating personnel and improved in safety performance.

Description

technical field [0001] The invention relates to a scaffold safety device, in particular to a scaffold non-kinetic energy anti-drop safety lock. Background technique [0002] At present, the scaffolding of high-rise buildings generally adopts attached lifting scaffolding, which can be lifted and lowered along with the construction progress of the building. When lifting, the scaffolding needs to move up and down, and safety performance is the most important consideration. In order to prevent it from falling suddenly, the traditional The mobile scaffold adopts a very complicated safety device in structure and installation to ensure that the scaffold does not fall suddenly when it is moving. This kind of complicated safety device has a high failure rate and is very cumbersome, and requires specific operators to operate. The failure of the anti-fall device can also cause the scaffold to fall, causing a safety accident. Contents of the invention [0003] The object of the prese...
