A tower crane connection structure

Abstract

The invention discloses a tower crane connection structure, which mainly includes an outer frame, a side shaft, a motor, a steel cable, a control box, a car, a guide rail, an electromagnetic engaging frame, a sliding seat and a locking box, and the upper and lower ends of the outer frame are fixed A reinforcement frame is installed, and a symmetrical triangular bracket is fixedly installed on the edge of the reinforcement frame. The middle part of the inner side of the outer frame is rotatably installed with a central shaft, and the outer side of the central shaft is fixedly installed with a front and back symmetrical outer winding frame. A front and back symmetrical rotary sleeve is installed for rotation, and an inner winding frame is fixedly installed on the outer side of the rotary sleeve. The present invention is structurally designed reasonably, and through a flexible and reasonable connection structure, the car can move up and down for personnel transportation, has good expandability, adapts to the use environment of the tower crane, and has better safety, and has double lock shafts and reasonable The advanced anti-fall structure, through the soft and slow falling method, avoids the instantaneous impact of internal personnel when stopping, making it safer to use. At the same time, it is equipped with active steel cable detection to prevent problems before they happen.

Description

technical field [0001] The invention relates to tower crane equipment, in particular to a tower crane connection structure. Background technique [0002] Tower crane is the most commonly used lifting equipment on construction sites, also known as "tower crane". , concrete, steel pipes and other construction raw materials. The tower crane is an indispensable equipment on the construction site. The function of the tip of the tower crane is to bear the upper load from the jib pull rope and the balance arm pull rope, and pass the structure of the rotating tower, turntable, bearing seat, etc. The component type is directly transferred to the tower structure through the turntable. The top of the self-elevating tower has a truncated cone column type, a forward or backward truncated cone column type, a herringbone frame type and a diagonal support frame type. [0003] The operating room of the existing tower crane is mostly fixedly connected to the tower crane, and the connection...

AI Technical Summary

Problems solved by technology

[0003] The operating room of the existing tower crane is mostly fixedly connected to the tower crane, and the connection structure is simple. It is directly fixed on the tower crane, causing the operator to manually climb up and down when moving up and down, which is very inconvenient and cannot effectively move the top and bottom. The transportation connection affects the efficiency and poor safety. At the same time, the structure of the existing upper and lower transportation devices is unstable, which leads to the inability to guarantee the safety of personnel moving up and down, and the expansion is poor.
