Problems solved by technology

[0005] A standard section introduction platform is set on the side of the introduction surface. After the standard section is hoisted onto the platform, the standard section moves forward freely with the introduction rollers during the jacking process. There are potential safety hazards due to the unrestricted movement range; and After the standard section is in place, it is inconvenient to disassemble the introduction roller, and the standard section needs to be lifted manually

Embodiment 1

[0023] Example 1 is attached Figure 1~3 As shown, the climbing frame includes an introduction surface S2, a climbing surface S1 opposite to the introduction surface S2, and two connecting surfaces connected between the introduction surface S2 and the climbing surface S1, wherein the introduction surface S2, the climbing surface S1 and the two connecting surfaces The surfaces are connected together by the main chords of the climbing frame to form a frame structure with a quadrilateral cross section. The main chords include two first main chords 2 arranged on the side of the introduction surface S2 and two first main chords 2 arranged on the side of the climbing surface S1. The two second main chords 1 of the tower body are provided with a set of roller devices at the four corners of the climbing frame, and each set of roller devices includes two guide rollers 11 arranged perpendicular to each other and in rolling contact with the same main chord of the tower body. , each guide...

Embodiment 2

[0027] Example 2 as Figure 4 As shown, the difference from Embodiment 1 is only that the stopper assembly 4 is not provided.

[0028] Taking Example 1 as an example, during the specific operation, use the main hook to hoist the standard section 8 onto the introduction platform 5, and the frame of the standard section 8 is pressed on the standard section 8. Since the roller 7 is inclined, the standard section 8 will move down to the block assembly 4, blocked by the block assembly 4, and not moving. When the standard section 8 needs to be installed, start the rotating motor, and the rotation of the roller 7 will drive the standard section 8 to move and squeeze the slider. The thickness of the slider towards the side of the introduction surface S2 gradually becomes smaller, so the standard section 8 continues to push the slider, so that the spring is squeezed, the slider is pressed into the sliding cavity, and the standard section 8 smoothly moves from the introduction platform ...

Abstract

The invention discloses a tower crane climbing frame, relates to the technical field of tower cranes. The tower crane climbing frame comprises a leading-in surface, a climbing surface opposite to the leading-in surface, and two connecting surfaces connected between the leading-in surface and the climbing surface; the leading-in surface, the climbing surface and the two connecting surfaces are connected together through main chord members of the climbing frame to form a frame structure with a quadrangular cross section, and a leading-in platform is hinged to one side of the leading-in surface and is connected to the first main chord member through a steel rope; a plurality of rollers for driving standard knots to move towards the interior of the climbing frame are arranged on the leading-in platform, the rollers are rotationally connected to the side wall of the leading-in platform, the connecting line of the axes of the rollers inclines towards one side of the leading-in surface, and the roller far away from one end of the leading-in surface is located at the high end. Movement of the standard knots is achieved through the rollers obliquely arranged on the leading-in platform, the standard knots do not need to be disassembled in the mounting process, the mounting time of the standard knots is shortened, and the difficulty is lowered.

Description

technical field [0001] The invention relates to the technical field of tower cranes, in particular to a tower crane climbing frame. Background technique [0002] In recent years, with the in-depth development of the construction industry, tower cranes (also referred to as "tower cranes") have been widely used. The promotion and use of tower cranes has gradually changed the vertical and horizontal transportation methods of construction, created safe working conditions for operators, and improved work efficiency. [0003] The climbing frame is an important part of the tower crane. It is set on the tower body of the tower crane. When the tower crane is working on the construction site, when it needs to be raised, the tower body is jacked up through the climbing frame and the jacking system set on the climbing frame. The upper part of the tower crane is introduced with an integral standard section to increase the height of the tower crane. The climbing frame plays an important...
