Description

Modularized tower crane connecting piece Technical Field The utility model relates to the technical field of tower crane connectors, in particular to a modularized tower crane connector. Background The tower crane connecting piece is a key element for connecting various parts of the tower crane. Chinese patent No. 201520306295.5 discloses the shaping connecting piece in the tower crane, and this shaping connecting piece includes frock frame (1), and the up end welding of the four corners of frock frame (1) is single otic placode (2), establishes round pin axle (3) and locating sleeve (4) on single otic placode (2), and locating pin (5) are established at the upper end center of the four corners of frock frame (1), and lower terminal surface welding double lug plate (6) in the four corners of frock frame (1) also establishes round pin axle and locating sleeve on double lug plate (6). When the vibration-damping device is used, the vibration-damping effect is poor, and the phenomenon that vibration is generated cannot be avoided when the vibration-damping device is used, so that the use stability of the tower crane is affected. Disclosure of utility model The utility model aims to provide a modularized tower crane connecting piece, which is used for solving the problems in the prior art. The modularized tower crane connecting piece comprises a connecting piece and a connecting support, wherein the connecting piece comprises mounting plates and mounting cylinders, a damping mechanism is arranged between the mounting plates, a limiting mechanism is arranged in the middle between the mounting plates, the mounting cylinders are arranged at one side of the mounting plates, slots are formed in the periphery of the upper ends of the mounting cylinders, one end of the connecting support is inserted into the mounting cylinders, a baffle is welded on the upper side of the connecting support, a threaded rod is welded on the periphery of one end of the connecting support, the threaded rod is embedded into the slots, and nuts are rotatably arranged on the outer sides of the threaded rods. Preferably, triangular piles are arranged between the mounting cylinder and the mounting plate, and the triangular piles are welded on the outer side of the mounting cylinder and one side of the mounting plate. Preferably, the upper end of the slot is in a conical shape, and the large-caliber end is upward. Preferably, the damping mechanism consists of damping springs and dampers, wherein the upper end and the lower end of each damper are arranged between the mounting plates, and the damping springs are arranged between the mounting plates and are positioned outside the dampers.
