Detailed Description
The present utility model will be described in further detail with reference to the accompanying drawings for a better understanding of the objects, structures and functions of the present utility model.
As shown in fig. 1 to 4, the leveling device for the embedded support leg of the tower crane comprises a bracket 1, a support plate 2 arranged on the bracket 1, and a screw 3 arranged on the support plate 2. Specifically, the bracket 1 includes a plurality of support rods 11 welded on the lower surface of the support plate 2, two adjacent support rods 11 are connected through a reinforcing rod 12, and the reinforcing rod 12 is connected with the support rods 11 in a welding manner. Preferably, the support plate 2 is a triangular plate, and the support rods 11 are respectively connected at three vertexes of the triangular plate.
The support plate 2 is provided with a through hole penetrating through the support plate 2, the through hole is positioned at the center of the support plate 2, and the through hole is provided with internal threads. The screw 3 is screwed in from the lower end of the through hole and protrudes from the upper end of the through hole, the screw 3 being provided with a first nut 4 between its head 31 and the through hole. Preferably, said through hole with internal threads is formed by a second nut 5 provided on the support plate 2. Specifically, the supporting plate 2 is provided with a mounting hole, the second nut 5 is fixedly arranged in the mounting hole, and the upper and lower end surfaces of the second nut 5 extend out relative to the upper and lower surfaces of the supporting plate 2.
When the tower crane leveling device is used, as shown in fig. 5 and 6, the distance between the lower plane of the tower crane supporting leg and the foundation cushion layer of the tower crane is calculated through the thickness of the foundation of the tower crane and the pre-buried depth of the supporting leg of the tower crane, materials used by the pre-buried supporting leg leveling device of the tower crane are prepared in advance, and when more tower cranes exist, the materials used by the quick leveling device of the supporting leg of the tower crane can be processed in batches, so that the construction time is shortened.
