Falling Prevention Structure for Attached Lift Scaffold

Abstract

A falling prevention structure can be stably connected to an attached lift scaffold body and is provided with a hinge point in the middle. The control arm is on one side of the hinge point, and an extension portion of the control arm can be connected/matched with a lifting structure of the attached lift scaffold. An operating arm is on the other side of the hinge point, an extension portion of the operating arm is provided with a transition structure and connected to a falling prevention pin by the transition structure. The falling prevention pin is provided with an elastic restoring structure and is capable of extending and retracting, and the extending falling prevention pin can be inserted into a clamping and hanging structure in a falling prevention structure directly or indirectly fixed to a building object.

BRIEF DESCRIPTION OF THE DRAWING

[0019] FIG. 1 is a schematic diagram of a falling prevention structure for an attached lift scaffold according to the present invention.

DETAILED DESCRIPTION

[0020] As shown in FIG. 1, in a falling prevention structure for an attached lift scaffold according to the present invention, on a leveraged structure 3 that can be stably connected to an attached lift scaffold body and is provided with a hinge point 4 of a hinge structure by conventional means in the middle, a control arm 2 is on one side of the hinge point 4, and an extension portion (usually an end portion) of the control arm 2 can be connected/matched with a lifting structure 1 (such as a lifting hook of an electric loop chain of a conventional hoist) of the attached lift scaffold; an operating arm 5 is on the other side of the hinge point 4, an extension portion (usually an end portion or a proximal portion) of the operating arm 5 is provided with a transition structure 6 in the form of a connecting rod or the like and connected to a falling prevention pin 8 by the transition structure 6, the falling prevention pin 8 is provided with an elastic restoring structure 7 in a proper form such as a compression spring and is capable of extending and retracting, and the extending falling prevention pin (8) can be inserted into a clamping and hanging structure 9 such as a clamping hole in a falling prevention structure 10 such as a falling prevention steel plate directly or indirectly fixed to a building object 11 to achieve falling prevention clamping and hanging cooperation. The leveraged structure 3 is of a turning structure with a right angle or other proper turning angle in the middle, the hinge point 4 is arranged at a turning position where the turning angle is located, and a length of the control arm 2 between the hinge point 4 and a portion of connection/matching with the lifting structure 1 of the attached lift scaffold is smaller than a length of the operating arm 5 between the hinge point 4 and a portion of connection with the transition structure 6. The transition structure 6 and the falling prevention pin 8 capable of extending and retracting are of an integral rod structure.
