Problems solved by technology

[0004] The present invention proposes a tower crane capable of preventing materials from shaking, which solves the problems of the existing tower cranes. When lifting objects, the hook is prone to shake and has poor stability. , it is easy to cause impact on the upper parts, and it is easy to cause damage to the parts. In addition, there is no corresponding anti-falling function on the hook, which cannot effectively prevent the phenomenon of objects falling off.

Abstract

The invention belongs to the field of tower cranes, and particularly relates to a tower crane capable of preventing a material from shaking. Aiming at solving the problems that as for an existing tower crane, when the material is lifted by a lifting hook, shaking is prone to occurring, stability is poor, in the event of misoperation of a worker, when the lifting hook ascends, an upper part is prone to being impacted, the part is prone to being damaged, in addition, a corresponding anti-falling function is not set on the lifting hook, and the phenomenon of material falling cannot be effectivelyprevented from occurring, the following scheme is put forward currently, specifically, the tower crane comprises a base; a tower body is fixed to the top of the base, and a crane boom is fixed to thetop of the tower body; and a fixed seat is fixed to the bottom of the crane boom, connecting blocks are fixed to the two sides of the bottom of the fixed seat correspondingly, and a reel is rotationally connected between the two connecting blocks. Through an anti-shaking mechanism, the phenomenon that an object hung and buckled on the lifting hook shakes when being lifted by a lifting rope can beeffectively prevented, the tower crane has a good anti-shaking effect, and the working efficiency and stability of the tower crane are improved.

Description

technical field [0001] The invention relates to the technical field of tower cranes, in particular to a tower crane capable of preventing materials from shaking. Background technique [0002] The tower crane is the most commonly used lifting equipment on the construction site, also known as the tower crane. It is an indispensable equipment on the construction site. The function of the tower suspension tip is to bear the upper load transmitted by the jib stay rope and the balance arm stay rope, and transmit it directly through the turntable through the structural components such as the slewing tower, turntable, bearing, etc. For the structure of the tower body, there are truncated cone column type, forward or backward inclined truncated cone column type, herringbone frame type and oblique frame type on the top of the self-elevating tower. The balance weight is used to form the balance moment required by the design to act in the opposite direction to the lifting moment. [0...
