A tower crane with the function of all-round adjustment of the spatial position and posture of lifting parts

Abstract

A tower crane with the function of adjusting the spatial position of a lifting component omnidirectionally belongs to the technical field of tower cranes. The tower crane comprises two parallel lifting mechanisms and a trolley with a slewing gear; the two parallel lifting mechanisms are installed back and forth on balance arms of the tower crane in the axis direction; the trolley is connected to a lower chord member of a crane jib, and slides along the crane jib; lifting steel wire ropes on the two lifting mechanisms are connected to wedged joints of the crane jib through a guide rope pulley block on a tower head, a lifting weight limiter, a trolley center guide rope pulley block, a slewing beam guide pulley block on the trolley and a lifting pulley block as well as a guide pulley block of the slewing beam, a central guide rope pulley block and two anti-twisting device pulleys at the end of the crane jib; the lift or decent of the lifting pulley blocks is controlled through the lifting mechanisms. In the invention, the + / - 90 DEG rotation function of the lifting component can be achieved, and the spatial position of the lifting component can be adjusted omnidirectionally; different lifting components can be rotated and adjusted in place on a construction side, and the efficiency and construction quality are improved in the lifting process.

Description

technical field [0001] The invention belongs to the technical field of tower cranes, and in particular relates to a tower crane with the function of all-round adjustment of the space pose of lifting parts. Background technique [0002] In modern industrial and civil buildings, hoisting building components is large in size and relatively heavy in weight. Using traditional hoisting equipment requires manpower to rotate and position the building components on the construction site. Due to the large scale and weight of the components, the rotational moment of inertia It is also relatively large, which increases the labor intensity and work risk of the hoisting workers, which is not in line with the development direction of construction industrialization. Therefore, it is necessary to study the corresponding intelligent level of building component dispatching equipment to reduce the labor of workers during assembly. Strength, greatly reduce the safety risk in the assembly process...
