Problems solved by technology

like figure 1 As shown, since the upper chord 50' of the jib root joint is under a greater force, the width of the pin connecting lug 10' is much larger than the height of the upper chord 50' of the jib to meet the requirements of the jib root. In this way, the height of the boom will be greatl

Embodiment Construction

[0030] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0031] like Figure 2 to Figure 10 As shown, according to the embodiment of the present invention, the pin connection structure includes a pin connection lug 10 , a connection pin 20 , and a pin bracket 30 . The two pin-shaft connection lugs 10 are fixedly connected to the ends of the chord 50 and arranged relatively parallel. The two pin connecting lug plates 10 include an upper connecting plate 11 arranged above and a lower connecting plate 12 arranged below. Both the upper connecting plate 11 and the lower connecting plate 12 are fixedly connected to the chord 50 horizontally and horizontally. The upper connecting plate 11 and the lower connecting plate 12 are oppositely provided with pin connec...

Abstract

The invention provides a pin shaft connecting structure, assembling and disassembling methods thereof and a tower crane. The pin shaft connecting structure comprises two pin shaft connecting ear plates (10) which are fixedly connected to the end parts of a chord member (50) and are arranged oppositely and connecting pin shafts (20) which are arranged in pin shaft connecting holes of the two pin shaft connecting ear plates (10); each of the two pin shaft connecting ear plates (10) comprises an upper connecting plate (11) arranged at the upside and a lower connecting plate (12) arranged at the downside; the upper connecting plates (11) and the lower connecting plates (12) are respectively transversely connected to the end part of the chord member (50); and the connecting pin shafts (20) are vertically mounted in the pin shaft connecting ear plates (10). According to the pin shaft connecting structure, disclosed by the invention, the height of a cargo boom of the tower crane and transportation cost of the tower crane can be reduced without reducing structural intensity of the pin shaft connecting ear plates.

Description

technical field [0001] The invention relates to a connection structure of construction machinery, in particular to a pin connection structure, its installation and disassembly method, and a tower crane. Background technique [0002] The pin connection structure has a very important position in the connection structure between the various components of the tower crane, and can connect the various components of the tower crane together safely and effectively. Because the connecting lugs of the pin-shaft connection structure are subjected to a large force, in general, the pin-shaft connecting lugs need to have sufficient thickness and width to ensure the structural strength of the pin-shaft connection structure and prevent the pin-shaft connection structure from being used. During the process, due to the large force, the pin shaft connection lug plate was damaged, resulting in the instability of the connection structure of the tower crane. [0003] In order to prevent the pin-...
