This embodiment is provided to more fully describe the present invention to those skilled in the art.

Hereinafter, the present invention will be described in detail with reference to Figs. 1 to 8 according to an embodiment of the present invention.

In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention unclear.

A gantry fixing bolt 200 is installed on a vertical member of a section where a lifting ring 101 used for lifting the gantry 100 is installed in a gantry 100 used for constructing a high-rise building or an outer wall of an apartment, A gang-lifting safety device is installed adjacent to the upper portion of the gang-fixing bolt (200) so that the operator can not dismantle the gang-fixing bolt (200).

The gang lifting safety device includes a lifting ring 101 and a gangue fixing bolt 200 installed on a ganged vertical member 102 used for constructing an outer wall of an apartment, A base plate 50 fixed to the front surface of the vertical member 102; And is rotatably and restrained by a fixed shaft bolt 30 which is passed through the base plate member 50 and is fastened to the nut at the upper side of the front surface of the base plate member 50. The fixed shaft bolt 30 A safety cover 10 formed symmetrically in a " C " A torsion spring (not shown) is installed inside the safety cover 10 with the fixed shaft bolt 30 inserted therein and both ends of the torsion spring are brought into close contact with the upper ends of the pair of safety covers 10 to apply an elastic force to the safety covers 10 40); The pulling bolt 60 is inserted into the end portion of the pulling bracket 20 which is bent and bent in the form of a 'C' at both sides of the safety cover 10 so as to penetrate the safety ring 80, And a fixing member (70) having a through hole formed at one side thereof so that the end of the pulling bolt (60) presses the outer peripheral surface of the safety hook (80). The pulling bracket (20) And the pulling bolt 60 is inserted into the other end of the fixing member 70 to fix the fixing member 70 so that the pulling bracket 20 is moved outward when the safety ring 80 is moved upward And the lower side of the safety cover 10 flares outward about the fixed shaft bolt 30 as the movable cover 10 is moved.
As described above, the safety cover 10 blocks both sides of the gang-fixing bolt 200 and the front portion of the gang-fixing bolt 200 in order to prevent the gang-fixing bolts 200 from being exposed to the outside and being disassembled arbitrarily.
One end of the fixing bolt 70 is rotatably fixed to the fixing member 70 raised at both sides of the safety cover 10 at the same time as the safety bolt 80, The pulling bracket 20 is formed of a plate material and one end thereof is bent at an angle of 90 degrees so that the safety cover 10 can be opened to the rear side of the center portion of both sides of the safety cover 10, And the other end is rotated about the pull bolt 60 when the fixing member 70 is moved upward and the other end is moved outward so that the safety cover 10 is fixed to the safety cover 10, .
Therefore, the pulling bracket 20 can prevent the pulling bracket 20 and the connecting portions from being damaged as compared with the pulling method in which the force acts in the upper diagonal direction and acts vertically upward as shown in FIGS. 6 to 8 .
At this time, the pair of safety covers 10 can be opened or closed.
