DETAILED DESCRIPTION

[0038] The preferred embodiments of the present application will be described in detail below with reference to the drawings, wherein the drawings constitute a part of the present application and serve to explain the principles of the present application together with the embodiments of the present application, but are not intended to limit the scope of the present application.

[0039] Example 1

[0040] One specific embodiment of the present application, as shown in Figure 1 discloses a mounting assembly of a truss rack, comprising a support assembly 1 and an adjusting assembly 2.

[0041] As shown in Figure 2 , the support assembly 1 comprises an upper support plate 11, a reinforcing side plate 12 and a lower support plate 13.

[0042] Exemplarily, the upper support plate 11 and the lower support plate 13 are the same in shape and structure. Preferably, in order to avoid the welds when the two adjacent rack connecting pipes 3 are welded, the upper support plate 11 and the lower support plate 13 are both arranged as L-shaped plates. Correspondingly, the first through hole 111 is arranged on the upper support plate 11; the second through hole 131 is arranged on the lower support plate 13, and the adjusting assembly 2 is arranged through the first through hole 111 and the second through hole 131. Preferably, in order to facilitate the installation of the adjusting assembly 2 and facilitate the stress distribution of the support assembly 1, the first through hole 111 and the second through hole 131 are arranged at the intersection of the two side plates of the upper support plate 11 and the lower support plate 13.

[0043] The reinforcing side plate 12 is arranged between the upper support plate 11 and the lower support plate 13 and is welded to the upper support plate 11 and the lower support plate 13. Preferably, the reinforcing side plate 12 is perpendicular to the upper support plate 11 and the lower support plate 13 in the height direction, so as to better support the external load.

[0044] The reinforcing side plate 12 is arranged on both sides of the first through hole 111 and the second through hole 131, tangent to the first through hole 111 and the second through hole 131, and extends outward along the tangent direction. The end of the reinforcing side plate 12 away from the first through hole 111 and the second through hole 131 is provided with a notch for welding the rack connecting pipe 3. After the adjusting assembly 2 is installed in the first through hole 111 and the second through hole 131, the reinforcing side plate 12 is arranged on both sides of the adjusting assembly 2 and is tangent to the outer wall surface of the adjusting assembly 2. The two reinforcing side plates 12 form an included angle, and the size of the included angle corresponds to the size of the included angle of the rack connecting pipe 3 welded on both sides.

[0045] In some embodiments, in order to facilitate welding and improve the connection strength of the reinforcing side plate 12 and the adjusting assembly 2, two reinforcing side plates 12 are arranged on both sides of the adjusting assembly 2 to form a predetermined included angle. In other embodiments, in order to reduce costs and improve production efficiency, the reinforcing side plate 12 is an L-shaped plate having two side surfaces with a predetermined included angle, and the two side surfaces are tangent to the outer wall surface of the adjusting assembly 2.

[0046] The reinforcing side plate 12 in the utility model is arranged on both sides of the adjusting assembly 2 and is tangent to the outer wall surface of the adjusting assembly 2, and the upper end and the lower end are welded to the upper support plate 11 and the lower support plate 13, respectively. On the one hand, the stability of the support assembly 1 can be increased, and on the other hand, the stress structure of the installed assembly during loading can be optimized.

[0047] The adjusting assembly 2 penetrates the upper support plate 11 and the lower support plate 13 and is connected with the upper support plate 11, the reinforcing side plate 12 and the lower support plate 13. The adjusting assembly 2 can move in a direction perpendicular to the upper support plate 11 and the lower support plate 13 to adjust the connection position of the installed assembly and the external component.

[0048] As shown in Figure 3 The adjusting assembly 2 includes an installation pipe 22 and an installation table 21. Exemplarily, the installation table 21 is a cylindrical structure arranged at the end of the installation pipe 22. The upper end surface of the installation table 21 is an installation surface 211 for connecting with the external component.

[0049] The installation pipe 22 penetrates the first through hole 111 and the second through hole 131 and can move in the first through hole 111 and the second through hole 131. The installation table 21 protrudes from the upper part of the upper support plate 11. The installation table 21 can adjust the position of the installation surface 211 to the required installation position by moving the installation pipe 22.

[0050] The mounting method of the embodiment is as follows:

[0051] Step 1: weld the support assembly 1; weld the upper support plate 11, the reinforcing side plate 12 and the lower support plate 13;

[0052] Step 2: weld the support assembly 1 to the rack;

[0053] Step 3: mount the mounting pipe 22 into the first through hole 111 and the second through hole 131, and adjust the mounting surface 211 to the required position;

[0054] Step 4: as shown in Figure 4 and Figure 5 , weld the mounting pipe 22 to the support assembly 1.

[0055] Compared with the mounting joint of the truss rack formed by overall machining in the prior art, the mounting assembly of the embodiment is formed by welding low-cost plates and pipes, which reduces the cost and saves materials. At the same time, before welding the adjusting assembly 2, the adjusting assembly 2 can move in a direction perpendicular to the upper support plate 11 and the lower support plate 13 to adjust the mounting surface 211 to the required position, which avoids the phenomenon that the mounting surface 211 of the mounting joint in the prior art is fixed and deformed after welding the rack connecting pipe 3 to deviate from the mounting position, and improves the safety and stability of the connecting part.

The mounting inner pipe 222 is threadedly connected with the mounting outer pipe 221. In the embodiment, the mounting position of the mounting table 21 is adjusted by adjusting the length of the mounting inner pipe 222 screwed into the mounting outer pipe 221, without using clamps or other auxiliary tools, which is simple and convenient to operate.

[0059] The mounting table 21 is arranged at the end of the mounting inner pipe 222.

[0060] In the embodiment, the mounting outer pipe 221 is arranged in the first through hole 111 and the second through hole 131, and is welded to the upper support plate 11, the reinforcing side plate 12 and the lower support plate 13.

[0061] Further, in order to improve the support effect of the mounting pipe 22 on the mounting assembly, the embodiment is provided with a stud 2212 inside the mounting outer pipe 221, which forms a cavity structure with the inner wall of the mounting outer pipe 221, for accommodating the mounting inner pipe 222. Correspondingly, the inner wall of the mounting inner pipe 222 is provided with an internal thread, for screwing with the stud 2212.

[0062] In the embodiment, after the mounting inner pipe 222 and the mounting outer pipe 221 are installed, the support effect of the hollow mounting pipe 22 in the embodiment 1 is changed to be borne by the mounting outer pipe 221, the mounting inner pipe 222 and the stud 2212, so as to improve the support and carrying capacity of the whole mounting assembly.

[0063] Further, in order to improve the installation precision and accurately control the installation distance of the mounting surface 211 and the external component, the embodiment is provided with a scale table 2221 on the outer wall of the mounting inner pipe 222 along the axial direction, the scale of the scale table 2221 corresponds to the pitch of the stud 2212, and the number of turns of the mounting inner pipe 222 screwed into the mounting outer pipe 221 is determined by reading the scale table 2221. The outer side of the mounting outer pipe 221 is provided with a scale disc 2211 along the circumferential direction, the scale disc 2211 is an angle scale disc 2211, and the angle of the mounting inner pipe 222 screwed into the mounting outer pipe 221 is determined by the scale disc 2211, so as to quantitatively adjust the position of the mounting table 21 and the mounting surface 211.
