Description

Technical Field

[0001] This invention relates to the field of engineering machinery technology, and in particular to a pull plate bracket assembly and a boom device. Background Technology

[0002] For a series of crane products, some boom sections have the same main structure, but the distance between the tie plates matched with the booms of different products is different. This results in different positions of the tie plate brackets used to support the tie plates, thus forming different boom sections. The versatility of boom sections between different products is greatly limited. Summary of the Invention

[0003] This invention provides a pull plate bracket assembly and a boom device to expand the application scope of the pull plate bracket assembly, reduce the types of boom sections, and improve the versatility of boom sections among a series of crane products.

[0032] The pull plate bracket assembly provided in this embodiment of the invention is used to fix the pull plate on the boom, thereby supporting the pull plate and fixing it during transport with the boom.

[0033] refer to Figure 2 and Figure 9 This invention provides a pull plate bracket assembly, which includes a pull plate bracket 11 and at least one limiting bracket 12. The pull plate bracket 11 is configured to be fixedly connected to a boom 30. The pull plate bracket 11 includes a vertical plate 111 for supporting a pull plate 20. At least one limiting bracket 12 is detachably connected to the vertical plate 111. The limiting bracket 12 includes two slots 121 located at the bottom end and spaced apart along the length of the vertical plate 111, and two connecting holes 122 located on both sides along the thickness of the vertical plate 111. The limiting bracket 12 is engaged with the vertical plate 111 through the two slots 121, and the vertical plate 111 is connected to the limiting bracket 12 through the two connecting holes 122.

[0034] The pull plate bracket assembly of this invention provides at least one detachably connected limiting frame 12 on the pull plate bracket 11. This allows for quick adjustment of the limiting gap of the pull plate bracket by connecting the limiting frame 12 to the pull plate bracket 11, thereby making the pull plate bracket assembly adaptable to different pull plate pitches, thus improving the versatility of the pull plate bracket assembly and expanding its application range.

[0035] When connecting the limiting frame 12 to the upright plate 111, first, the slot 121 of the limiting frame 12 is snapped into the upright plate 111, and the connecting piece is passed through the two connecting holes 122 to connect the limiting frame 12 and the upright plate 111.

Adjacent limiting plates 112 are connected by a first connector 15. A limiting bracket 12 may be optionally disposed between adjacent limiting plates 112. Figure 1 As shown, when the distance between the two limiting plates 112 is too large, a limiting frame 12 can be set between the two limiting plates 112 so that a limiting space for supporting the pull plate 20 is formed between the limiting frame 12 and the limiting plate 112. In some other embodiments, the position of the limiting frame 12 can be adjusted according to the size of the pull plate distance, or the limiting frame 12 can be set between other limiting plates.

[0037] like Figure 4 As shown, the pull plate bracket 11 includes an upright plate 111 and at least two limiting plates 112 disposed on the upright plate 111. The at least two limiting plates 112 are spaced apart along the length of the upright plate 111. A limiting space for the pull plate is formed between two adjacent limiting plates 112.

[0038] like Figure 5 As shown, in some embodiments, at least two limiting plates 112 include two end limiting plates disposed at both ends of the vertical plate 111 along its length and an intermediate limiting plate located between the two end limiting plates. The two end limiting plates are integrally formed with the vertical plate 111, and the intermediate limiting plate is connected to the vertical plate 111. Specifically, the end limiting plates are formed by bending, and the intermediate limiting plate is welded to the vertical plate 111.

[0039] like Figure 5 As shown, the intermediate limiting plate includes a vertical section, a first horizontal section disposed at the upper end of the vertical section, and a second horizontal section disposed at the lower end of the vertical section. Both the first and second horizontal sections are perpendicular to the vertical section and extend in the opposite direction. When welded to the upright plate 111, the second horizontal section is engaged with the lower side of the upright plate 111, and the vertical section is welded to the upright plate 111. The intermediate limiting plate is perpendicular to the surface of the upright plate 111.

[0040] like Figure 2As shown, the two intermediate limiting plates are connected by a first connecting member 15. The intermediate limiting plates and the end limiting plates are connected by another first connecting member 15. Figure 1 As shown, one pull plate 20 is supported between the intermediate limiting plate and the limiting frame 12, and another pull plate 20 is supported between the intermediate limiting plate and the end limiting plate. The limiting plate 112 and the limiting frame 12 are used to limit the movement of the pull plates, and the first connecting member 15 is used to limit the rotation of the pull plates.

[0041] The first connector 15 is a pin. One end of the first connector 15 is provided with a limit end, and the other end is limited by a clip 13.

[0042] like Figure 3 As shown, the pull plate bracket assembly also includes a second connector 18. The second connector 18 passes through two connecting holes 122 to connect the upright plate 111 and the limiting bracket 12. The second connector 18 may also be a pin.

The first limiting frame and the second limiting frame are respectively disposed on both sides of the pull plate 20 to form a limiting action, and the first connecting member 15 is disposed above the pull plate 20 to limit the pull plate 20. Figure 8 As shown, the upright plate 111 is connected to the web member 40 of the boom. The first and second limiting brackets limit the movement of the pull plate 20. The first connecting piece 15 is disposed above the pull plate 20 to limit the rotation of the pull plate 20.
