A separate climbing frame protection device

Abstract

The invention discloses a detachable protection device for a climbing frame, comprising a connecting rod (5) for fixing the ear plate of the climbing frame, and a connecting ear plate (4) for connecting the ear plate of the climbing frame; the connecting rod (5) ) both ends are fixedly connected to the ear plate (4), and the length is the same as that of the narrow ear plate half (1) and the wide ear plate half (2); the distance between the connecting ear plates (4) is the same as that of the narrow ear plate half (1) The distance between the ear plates and the distance between the lug plates of the half of the wide ear plate (2) match, and the connection holes (4‑1) are provided on the connecting ear plates (4). In the present invention, when the separated climbing frame is separated, the ear plates of the two separated parts are respectively connected through the protective device, the structure is stable, and the deformation problem of the separated two parts of the ear plates in the process of welding and transportation is reduced; the device It is a movable structure, which is convenient for installation and removal, and does not affect the assembly and use of the climbing frame.

Description

technical field [0001] The invention relates to a crane climbing frame accessory, in particular to a separated climbing frame protection device. Background technique [0002] The climbing frame is a structure that cooperates with jacking devices such as jacking cylinders to change the height of the tower crane by adding or subtracting standard joints. At present, the climbing frame of the tower crane is generally a whole, but when it is necessary to use a container for export and other reasons, the section of the integral climbing frame is too large to fit into the container, and the climbing frame needs to be designed as a separate type. [0003] Such as figure 1 As shown, the separated climbing frame structure includes the narrow lug half part 1 and the wide lug half part 2. During the transportation, the two are separated. When assembled and used, as figure 2 As shown, the mounting holes at the front ends of the narrow ear plate half 1 and the wide ear plate half 2 mat...

AI Technical Summary

Problems solved by technology

Since the lug end used for connection is in a free state without any protection, it is easy to deform the lug end due to bumps and other reasons during the production and transportation process, making it impossible to assemble the climbing frame as a whole, which seriously affects the installation efficiency
