Problems solved by technology

[0003] In the prior art, after the material is hoisted by the crane, the boom rotates around the turntable. During this process, the material not only has a certain vertical distance from the boom, but also has a horizontal distance from the tower body. Swing, which has adverse effects on the bearing capacity of the boom and the stability of the tower

Embodiment Construction

[0014] Embodiment 1 of the present invention proposes an anti-swing tower crane for transporting materials 14, such as figure 1 and figure 2 As shown, it includes: base 1, tower body 2, turntable 3, boom 4, lifting and traveling device 5, balance arm 6, hook 7, counterweight 8, counterweight traveling device 9, tower tip 10, bracket 11, Baffle plate 12, rope 13. Among them, the tower body 2 is fixed on the base 1; the tower tip 10 is set on the top of the tower body 2; the turntable 3 is located between the tower body 2 and the tower tip 10; the left and right sides of the turntable 3 are fixed with a boom 4 and a balance arm 6; The lifting and traveling device 5 with the suspension hook 7 is movably installed on the boom 4, which is used to release and retract the cable under the drive of the motor to make the suspension hook 7 take materials, then move along the direction of the boom 4, and turn to Unloading after the working area; a counterweight walking device 9 with a ...

Abstract

The invention discloses an anti-swing tower crane. A rope is shortened as much as possible after materials are lifted, so that the materials are close to a lifting arm as much as possible, the materials are driven to move to a position close to the tower body by a lifting and traveling device and are fixed by a fixing bracket arranged at a corresponding position of the tower body, a rotary table is driven to a specific angle, and the lifting and traveling device drives the materials to move to an operating area to be discharged. Because the materials are close to the lifting arm and the tower body as much as possible in the process of rotating the rotary table and are fixed by the fixing bracket, the materials do not swing after the rotary table stops, and bad influence to the bearing force of the lifting arm and the stability of the tower body is avoided.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to an anti-swing tower crane. Background technique [0002] A crane refers to a multi-action hoisting machine that lifts vertically and carries heavy objects horizontally within a certain range. The working characteristics of the crane are intermittent movements, that is, the corresponding mechanisms for retrieving, moving, unloading and other actions work alternately in a working cycle. The hoisting machinery used in bridge construction projects can generally be divided into light and small hoisting equipment, bridge type hoisting machinery, jib type cranes, and cable cranes according to their structure and performance. Light and small lifting equipment such as: jacks, pneumatic hoists, electric hoists, balance hoists (also known as balance cranes), winches, etc.; bridge type lifting machinery such as beam cranes, etc.; Cranes, truck cranes, tire cranes, crawler cranes, etc. Amon...
