[0059] The technical solutions in the embodiments will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0060] In the description of the present invention, it should be understood that the terms "center", "lateral", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the scope of protection of the present invention.

[0061] like Figure 1 As shown, in one embodiment of the boom assembly tooling provided by the present invention, the boom assembly tooling includes an assembly platform 10, a positioning assembly and a leveling device 60, wherein the positioning assembly is arranged on the assembly platform 10, and the positioning assembly is used to position the boom 100, and the leveling device 60 is arranged on the assembly platform 10, and the leveling device 60 is used to level the boom 100.

[0062] In the above embodiment, the assembly of the boom 100 can be achieved by setting up an assembly platform 10, a positioning component and a leveling device 60. At the same time, the boom 100 can be positioned and leveled during the assembly process through the positioning component and the leveling device 60, which effectively improves the assembly efficiency and the assembly quality, avoids the problem of non-leveling during the assembly process, and further affects the welding quality in the subsequent welding process, which is beneficial to improving the overall quality of the boom.

[0063] Optionally, the positioning assembly includes a first positioning member 20 and a second positioning member 30 , the first positioning member 20 is mounted on the assembly platform 10 , the second positioning member 30 is mounted on the first positioning member 20 , and the second positioning member 30 is used to position the boom 100 .

[0064] like Figure 1 As shown, there are two first positioning members 20, which are respectively installed on the assembly platform 10 by bolts and washers. The arm 100 is located between the two first positioning members 20. The side of the first positioning member 20 is trapezoidal to enhance the stability of the first positioning member 20. A plurality of ribs and ribs are provided on the side of the first positioning member 20 away from the arm 100 to enhance the strength of the first positioning member 20.

[0065] like Figure 2 As shown, the second positioning member 30 includes a positioning body 31 and a plurality of first connecting holes 32. The positioning body 31 includes two flat plates, and a plurality of connecting plates are arranged between the two flat plates to enhance the strength of the second positioning member 30, and such an arrangement can reduce the weight of the second positioning member 30 as much as possible.

[0066] Optionally, the installation position of the first positioning member 20 on the assembly platform 10 is adjustable to accommodate various sizes of the boom 100 .

[0067] Optionally, the installation position of the second positioning member 30 on the first positioning member 20 is adjustable. A plurality of mounting holes are provided on one side of the first positioning member 20 close to the boom 100, and the second positioning member 30 is installed on the side of the first positioning member 20 close to the boom 100 by bolts or pins, so as to adjust the installation position of the second positioning member 30 on the first positioning member 20 according to actual needs to meet the needs in the height direction or other directions.

[0068] The boom 100 includes a main chord tube 101 and a belly tube 102 . The belly tube 102 is connected between two main chord tubes 101 . The cross section of the main chord tube 101 is L-shaped.

[0069] There are four main chord tubes 101. When assembling the boom 100, two main chord tubes 101 are first connected to form a first assembly by using the belly tube 102, and then the other two main chord tubes 101 are connected to form a second assembly by using the belly tube 102. The first assembly and the second assembly are vertically arranged opposite to each other. Compared with the scheme in which the first assembly and the second assembly are horizontally arranged opposite to each other up and down, the operating space can be increased, and the assembly of other connecting tubes of each belly tube is avoided from being affected by the limited operating space below.

[0070] The main chord tube 101 is connected by two connecting plates. Although the structure formed after the connection is similar to the angle steel, compared with the angle steel, it can avoid the arc transition angle at the connection between the two connecting plates, which affects the extension and retraction of the telescopic boom.

[0071] Optionally, the positioning assembly further includes a third positioning member 40 , which is mounted on the second positioning member 30 , and is used to position two inner side surfaces of the main chord tube 101 .

[0072] like Figure 1 As shown, for the right end of the arm 100 , its end face is the end face of the main chord tube 101 , and by providing the third positioning member 40 , the two inner side faces of the main chord tube 101 can be positioned.

[0073] Furthermore, the main chord tube 101 is overlapped on the third positioning member 40, and the two inner side surfaces of the main chord tube 101 are limited by the two side surfaces of the third positioning member 40. Since the cross section of the main chord tube 101 is L-shaped, the two inner side surfaces of the main chord tube 101 can be limited by overlapping the main chord tube 101 on the third positioning member 40. This positioning method is simple, reliable and easy to operate.

[0074] Furthermore, if Figure 3 As shown, the third positioning member 40 includes a first positioning plate 41, which is installed on the positioning body 31 of the second positioning member 30, and the first positioning plate 41 includes a first side surface and a second side surface adjacent to the first side surface. The main chord tube 101 includes a first inner side surface and a second inner side surface, and the first inner side surface is in contact with the first side surface, and the second inner side surface is in contact with the second side surface.

[0075] Taking the two main chord tubes 101 located in the upper row as an example, the openings of the two main chord tubes 101 are both facing inwards, and taking the direction shown in the figure as the reference direction, the two inner side surfaces of the main chord tube 101 located at the rear face one downwards and one forwards, the inner side surface facing downwards contacts the top surface of the first positioning plate 41 installed at the upper rear of the second positioning member 30, and the inner side surface facing forwards contacts the rear side surface of the first positioning plate 41; the two inner side surfaces of the main chord tube 101 located at the front face one downwards and one backwards, the inner side surface facing downwards contacts the top surface of the first positioning plate 41 installed at the upper front of the second positioning member 30, and the inner side surface facing backwards contacts the front side surface of the first positioning plate 41. The first positioning plate 41 at the upper rear and the first positioning plate 41 at the upper front can not only limit the forward and backward movement of the two main chord tubes 101, but also form upward support and positioning for the two main chord tubes 101.

[0076] The situation of the two main chord pipes 101 in the lower row is similar and will not be described in detail here.

[0077] Alternatively, if Figure 3 As shown, the third positioning member 40 further includes a second positioning plate 42, which is mounted on the second positioning member 30. The second positioning plate 42 is used to position the end surface of the main chord tube 101, and the first positioning plate 41 is mounted on the second positioning plate 42. The left and right movement of the main chord tube 101 can be limited by the second positioning plate 42 on the second positioning member 30 on the right side and the second positioning member 30 on the left side.

[0078] For the left end of the boom 100, a connection portion is provided at the end of the boom 100, and the positioning assembly further includes a fourth positioning member 50, which is mounted on the second positioning member 30 and connected to the connection portion. By providing the fourth positioning member 50, the positioning of the left side of the boom 100 can be achieved.

[0079] like Figure 4 As shown, the fourth positioning member 50 includes a third positioning plate 51, a fourth positioning plate 52 and a connecting member. The third positioning plate 51 is mounted on the second positioning member 30, the fourth positioning plate 52 is mounted on the third positioning plate 51, and the connecting member is used to connect the fourth positioning plate 52 and the connecting portion.

[0080] The third positioning plate 51 is provided with a second connection hole 53, and a bolt passes through the second connection hole 53 to achieve the connection between the third positioning plate 51 and the positioning body 31 of the second positioning member 30. The fourth positioning plate 52 is perpendicular to the third positioning plate 51, and the fourth positioning plate 52 is provided with a third connection hole 54, and a boss protruding relative to the fourth positioning plate 52 is provided around the third connection hole 54. The boss has a positioning function and can reduce the thickness of the fourth positioning plate 52 and reduce the weight of the entire fourth positioning member 50. The connecting member passes through the third connection hole 54 and the connecting hole on the connecting part to achieve the connection between the fourth positioning member 50 and the connecting part.

[0081] The connecting member may be a bolt or a pin, etc. The connecting portion may be a double-fork connecting structure, and the fourth positioning member 50 may be a single-fork connecting structure. The fourth positioning member 50 is inserted between the double-fork structures of the connecting portion to achieve connection.

[0082] The fourth positioning member 50 is provided with a lifting lug 55 for lifting, which facilitates lifting.

[0083] like Figure 5 As shown, the leveling device 60 includes a support, a first support rod 61 and a second support rod 62. The first support rod 61 is horizontally mounted on the support and is used to press against the top of the boom 100. The second support rod 62 is horizontally mounted on the support and is used to support the bottom of the boom 100, so as to adjust the horizontality of the boom 100 through the first support rod 61 and the second support rod 62. This can improve the assembly quality of the boom 100, and is also of great benefit to the subsequent welding process, which can prevent welding problems caused by uneven assembly and reduce the overall quality of the boom 100.

[0084] The support includes a support plate 63 and a vertical plate 64. The support plate 63 can be installed on the assembly platform 10 by bolts, and the vertical plate 64 is installed on the support plate 63. The first support rod 61 and the second support rod 62 are both installed on the vertical plate 64, with the first support rod 61 located at the top and the second support rod 62 located at the bottom. The first support rod 61 and the second support rod 62 are installed on the vertical plate 64 by threads, and a handle is provided at the end. By turning the handle, the extension length of the first support rod 61 and the second support rod 62 can be adjusted.

[0085] A first rib 65 and a second rib 66 are respectively provided on both sides of the vertical plate 64 to enhance the strength of the support.

[0086] Optionally, the heights of the first support rod 61 and the second support rod 62 are adjustable to accommodate arms 100 of different heights, thereby increasing the applicable range of the leveling device 60 .
