DETAILED DESCRIPTION

[0019] The technical solutions of the patent will be further described in detail in combination with specific embodiments.

[0020] Please refer to Figs. 1-3 A tower crane safety protective fence, comprising two bases 1 arranged symmetrically and spaced apart, the top of the base 1 is fixedly connected with a first plug-in sleeve 2, a first plug-in head 3 is movably inserted in the first plug-in sleeve 2, a first fixed bolt 4 is arranged horizontally between the first plug-in sleeve 2 and the first plug-in head 3, a stand 5 is integrally formed on the top of the first plug-in head 3, a hinge assembly 6 is fixedly connected on both sides of the stand 5, the other side of the hinge assembly 6 is fixedly connected with a second plug-in sleeve 7, a railing 8 is arranged between the two opposite second plug-in sleeves 7, the two ends of the railing 8 are fixedly connected with second plug-in heads 9, the second plug-in heads 9 are movably inserted in the second plug-in sleeves 7, and second fixed bolts 10 are arranged horizontally between the second plug-in heads 9 and the second plug-in sleeves 7. The arrangement of the base 1, the first plug-in sleeve 2, the first plug-in head 3, the first fixed bolt 4, the stand 5, the hinge assembly 6, the second plug-in sleeve 7, the railing 8, the second plug-in head 9 and the second fixed bolt 10 enables the base 1 and the stand 5 and the stand 5 and the railing 8 to be detachably connected, facilitating the carrying and transportation of the fence, and facilitating the separate replacement after local damage, thereby reducing maintenance costs.

[0021] Further, a cavity 11 is formed in the inside of the base 1, the first plug-in sleeve 2 is in conductive connection with the cavity 11, and sand is contained in the cavity 11. The self-weight of the base 1 can be increased by containing sand in the cavity 11, so that the center of gravity of the fence is lower and more stable, and the fence is not easy to be blown down by the wind. The first plug-in sleeve 2 is in conductive connection with the cavity 11, so that the sand in the cavity 11 can be poured out through the first plug-in sleeve 2 after use, thereby reducing the weight of the base 1 and facilitating carrying.
