For solving foretell technical problem, the utility model relates to a pre-buried fixing device of tower crane cross-section, constitute including first main limb, first horizontal support bar, second main limb and lower margin, the first horizontal support bar of upper end fixedly connected with of first main limb, first horizontal support bar and first connecting plate fixed connection, first connecting plate and second main limb fixed connection, second main limb and second connecting plate fixed connection, second connecting plate and second horizontal support bar fixed connection, second horizontal support bar and first main limb fixed connection.
Further, the lower part of first main limb is provided with two 65mm through-holes 65mm through-hole outside fixedly connected with first flitch, the downside of second main limb is provided with two 50mm through-holes, 50mm through-hole outside fixedly connected with second flitch.
Further, the 65mm through hole is movably connected with the connecting vertical pin, and the connecting vertical pin is movably connected with the connecting pin shaft.
Furthermore, the upper end of the first horizontal support rod is fixedly connected with a fixed steel plate, and the fixed steel plate is fixedly connected with the inclined support rod.
Furthermore, the first main limb and the ground foot are fixedly connected through a connecting vertical pin.
Compared with the prior art after adopting the above-mentioned structure, the utility model relates to a pre-buried fixing device in many cross-sections of tower crane, through main limb simulation mark vertebra festival mounting point, ensure that pre-buried lower margin and mark vertebra festival mounting point coincide, horizontal stay bar is formed by the channel-section steel welding, it is used for stabilizing whole firm frame structure to strengthen the diagonal stay, this device relative position and erection dimension satisfy the tower crane installation needs all the time, improve the pre-buried lower margin installation accuracy of tower crane, this patent adopts many sizes cross-section tower body and current a cross-section tower body technique to compare, can adapt to the pre-buried lower margin of two kinds of sizes tower body festival of 2 meters and 1.6 meters and use, also can use with the lower margin of two kinds of pre-buried sizes of needs when same basis, improve production efficiency in the use, structural reliable and stable will be in order to guarantee the installation accuracy, this fixing device installation.
