The invention belongs to the technical field of construction machinery, in particular to a tower crane platform. The tower crane platform comprises a supporting mechanism, wherein a plurality of bearing mechanism is arranged on the supporting mechanism, the supporting mechanism comprises an inner frame and an outer frame sleeved on the outer side of the inner frame, the inner frame and the outer frame are fixedly connected with a tower section through supports, and each bearing mechanism comprises two groups of bearing plates and sleeves; the two bearing plates at the lower part are pulled tothe outside, the two sleeves slide under the guide of a connecting rod, the bearing plates on one sides are rotated after sliding to a proper distance, the rotation unfolding direction of the bearingplates above the bearing plates corresponds to a corner, after the rotating adjustment is completed, under the tension of springs, the two sleeves drive the bearing plates to slide in the opposite direction until the two bearing plates are attached to each other, then the bearing plates at the upper part are rotated and unfolded, and the bearing plates are rotated to the horizontal state, so thatthe extension installation can be performed at the straight line and the corner, the adjustability is high, and the installation is more convenient.
Description
technical field [0001] The invention belongs to the technical field of construction machinery, and in particular relates to a tower crane platform. Background technique [0002] Tower crane is the most commonly used lifting equipment on construction sites, also known as tower crane. The last indispensable equipment, the function of the tower suspension tip is to bear the upper load transmitted by the jib stay rope and the balance jib stay rope, and transmit it directly to the Tower body structure, self-elevating tower top has truncated cone column type, forward or backward inclined truncated cone column type, herringbone frame type and diagonal brace type. [0003] The load-bearing bottom plate of the existing tower crane platform is a diamond-shaped metal mesh. Under natural conditions, the connection edge between the metal mesh and the fixed frame is prone to corrosion. security risks. Contents of the invention [0004] In order to solve the problems raised in the abo...
