In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0033] The present invention provides a steel truss positioning mechanism, which can realize the accurate positioning of multiple steel trusses 10 at a preset spacing, so as to be subsequently welded with the bottom plate to form the required steel truss floor deck. Figure 1-3 As shown, the steel bar truss positioning mechanism of this embodiment includes a positioning frame 1, a positioning lifting assembly 2, a material moving assembly 3 and an alignment assembly 4, wherein the positioning lifting assembly 2, the material moving assembly 3 and the alignment assembly 4 are all installed on the positioning frame 1, the material moving assembly 3 can transport the steel bar truss 10 along the width direction of the positioning frame 1, and position the steel bar truss 10 through the positioning lifting assembly 2, and the above-mentioned alignment assembly 4 can align one end of multiple steel bar trusses 10.

[0034] The positioning frame 1 is configured as a long frame structure according to the structure of the steel truss 10, that is, its length is relatively long so as to support the steel truss 10. Considering the relatively long length of the steel truss 10, the positioning frame 1 of this embodiment may include at least two segmented brackets, and the steel truss 10 is placed on the material moving assembly 3 along the length direction of at least two segmented brackets. That is to say, through the configuration of the segmented brackets, on the one hand, segmented brackets of different numbers can be selected and connected according to the different lengths of the steel truss 10, so as to meet the needs of the steel truss 10 of different lengths. On the other hand, it also avoids the positioning frame 1 being too long, resulting in poor overall structural strength and difficulty in processing and manufacturing.

[0035] In this embodiment, a first positioning plate 11 is fixed on the positioning frame 1, and the first positioning plate 11 protrudes from the top of the positioning frame 1, which can block and position the steel truss 10 when the material shifting assembly 3 transports the first steel truss 10. Optionally, a plurality of the above-mentioned first positioning plates 11 are provided, and the plurality of first positioning plates 11 are arranged on the positioning frame 1 at intervals along the length direction. Considering that the length of the steel truss 10 is relatively long, the steel truss 10 is positioned at multiple points by using a plurality of first positioning plates 11, so that the positioning of the steel truss 10 is more accurate. It can be understood that the positioning frame 1 includes at least two segmented brackets, and therefore the above-mentioned first positioning plate 11 is provided on each segmented bracket.

[0036] In this embodiment, reference can be made to Figure 4 The positioning lifting assembly 2 includes a lifting drive 21, a second positioning plate 22 and a positioning beam 23, wherein the lifting drive 21 is vertically arranged, and the output end is connected to the positioning beam 23, and the second positioning plate 22 is installed on the positioning beam 23, and the lifting drive 21 drives the positioning beam 23 to move up and down, so as to realize the up and down movement of the second positioning plate 22, and then the second positioning plate 22 can position the second and more steel bar trusses 10 transported by the material moving assembly 3 after rising. It should be pointed out that when the second positioning plate 22 is driven down by the lifting drive 21, the highest point of the second positioning plate 22 is lower than the top of the positioning frame 1, so as to avoid the second positioning plate 22 interfering with the transportation of the first steel bar truss 10.

[0037] Optionally, the lifting drive member 21 may be a cylinder or other components capable of driving the positioning beam 23 to lift. A plurality of lifting drives 21 may be provided, and the plurality of lifting drives 21 can synchronously lift the positioning beam 23. In addition, the positioning frame 1 includes at least two segmented brackets, so the lifting drive member 21 is installed on each segmented bracket, and a positioning beam 23 and a second positioning plate 22 are provided at each segmented bracket.

[0038] At least two second positioning plates 22 are provided, and at least two second positioning plates 22 are installed on the positioning beam 23 at intervals. Through at least two second positioning plates 22, the second and subsequent conveyed steel trusses 10 can be positioned at multiple points, so that the positioning of the steel trusses 10 is more accurate. Preferably, the second positioning plate 22 is installed on the positioning beam 23 in an adjustable manner. Specifically, a through hole is provided on the positioning beam 23, and a waist-shaped hole is provided on the second positioning plate 22. Bolts are passed through the waist-shaped hole and the through hole in sequence to fix the second positioning plate 22 on the positioning beam 23. Due to the setting of the waist-shaped hole, the position of the second positioning plate 22 on the positioning beam 23 can be adjusted.

[0039] It can be understood that in this embodiment, since the produced steel bar truss floor deck includes a plurality of steel bar trusses 10, the material moving assembly 3 will synchronously transport the plurality of steel bar trusses 10. Therefore, the positioning lifting assembly 2 is set to at least two groups according to the number of steel bar trusses 10. Specifically, the number of groups of the positioning lifting assembly 2 is the number of steel bar trusses 10 minus one. The at least two groups of positioning lifting assemblies 2 are arranged at intervals along the width direction of the positioning frame 1, and the spacing between the first positioning plate 11 and the adjacent second positioning plate 22 is the same as the spacing between the second positioning plates 22 of the two adjacent groups of positioning lifting assemblies 2, which are both the spacing between two adjacent steel bar trusses 10 on the steel bar truss floor deck.

[0040] In this embodiment, the positioning beam 23 is slidably placed on the positioning frame 1, and specifically, a slide rail is provided on the positioning frame 1, and a slider is provided on the positioning beam 23, and the slider slides on the slide rail to realize the sliding of the positioning beam 23 on the positioning frame 1. And through the structure of the slider and the slide rail, the positioning frame 1 cooperates with the lifting drive member 21 to support the positioning beam 23.

[0041] like Figure 2-5 As shown, the material shifting assembly 3 includes a material shifting motor 31, a material shifting chain 32, an active material shifting sprocket 33 and a driven material shifting sprocket 34. The material shifting motor 31 is mounted on the positioning frame 1, and a sprocket (not shown) is provided at its output end, which is connected to the active material shifting sprocket 33 through a chain drive. The active material shifting sprocket 33 is mounted on one side of the positioning frame 1 in the width direction, and the driven material shifting sprocket 34 is mounted on the other side of the positioning frame 1 in the width direction, and the active material shifting sprocket 33 is connected to the driven material shifting sprocket 34 through the material shifting chain 32. Specifically, the material shifting chain 32 is sleeved on the active material shifting sprocket 33 and the driven material shifting sprocket 34. The plurality of steel bar trusses 10 are placed on the material shifting chain 32, and are driven by the material shifting chain 32 to move along the width direction of the positioning frame 1, and can then be blocked and positioned by the first positioning plate 11 or the second positioning plate 22. It should be noted that when the steel truss 10 is blocked by the first positioning plate 11 or the second positioning plate 22 , the material transfer chain 32 will move relative to the blocked steel truss 10 , that is, it will not be affected by the blocked steel truss 10 .

[0042] In this embodiment, the active material transfer sprocket 33, the driven material transfer sprocket 34 and the material transfer chain 32 are provided in multiple groups, and the multiple groups of active material transfer sprocket 33, the driven material transfer sprocket 34 and the material transfer chain 32 are arranged at intervals along the length direction of the positioning frame 1. Then, the steel bar truss 10 is supported and transported by the multiple material transfer chains 32. Preferably, it can be referred to Figure 3 and Figure 5The material shifting assembly 3 of this embodiment further includes a material shifting shaft 35, which is rotatably connected to the positioning frame 1, and a plurality of active material shifting sprockets 33 are fixedly connected to the material shifting shaft 35 at intervals, and the material shifting motor 31 is drivingly connected to one of the active material shifting sprockets 33, and the material shifting motor 31 drives one of the active material shifting sprockets 33 to rotate, and the active material shifting sprocket 33 drives other active material shifting sprockets 33 to rotate synchronously through the material shifting shaft 35, thereby realizing the synchronous movement of multiple material shifting chains 32, so as to achieve the purpose of better conveying the steel bar truss 10. It can be understood that in other embodiments, the material shifting shaft 35 may not be provided, and in this case, each active material shifting sprocket 33 is correspondingly provided with a material shifting motor 31, and multiple material shifting motors 31 need to rotate synchronously.

[0043] It should be pointed out that when the positioning frame 1 includes at least two segmented brackets, a segmented rotating shaft is rotatably mounted on each segmented bracket, and the multiple segmented rotating shafts can be connected by couplings.

[0044] In order to better realize the stable conveying of the material transfer chain 32 to the steel bar truss 10, the material transfer assembly 3 of this embodiment also includes a tension support sprocket 36 ( Figure 4 As shown in the figure, the tension support sprocket 36 is rotatably arranged on the positioning frame 1, and the tension support sprocket 36 is chain-connected to the lower end of the material transfer chain 32 to tension and support the material transfer chain 32. It can be understood that a tension support sprocket 36 is provided for each material transfer chain 32.

[0045] In this embodiment, Figure 1 As shown, the alignment assembly 4 is disposed at one end of the positioning frame 1 in the length direction, and is used to align the ends of a plurality of steel trusses 10, thereby providing a basis for subsequent welding of steel truss floor decks. Figure 6 As shown, the alignment assembly 4 includes an alignment driver 41 mounted on the positioning frame 1, and an alignment plate 42 driven to move by the alignment driver 41. The alignment plate 42 is driven to move by the alignment driver 41, and the alignment plate 42 can align the ends of multiple steel bar trusses 10. In this embodiment, the alignment driver 41 can be a cylinder, or other components that can drive the alignment plate 42 to move linearly.

[0046] When the above-mentioned steel bar truss positioning mechanism of this embodiment is used, taking the steel bar truss floor deck including three steel bar trusses 10 as an example, the three steel bar trusses 10 are first placed on the material moving chain 32, and then the material moving motor 31 of the material moving assembly 3 drives the material moving chain 32 to move, and the material moving chain 32 moves the first steel bar truss 10 to the first positioning plate 11 and is blocked and positioned by the first positioning plate 11. At this time, the lifting drive 21 of the first positioning lifting assembly 2 drives the second positioning plate 22 to rise, and then the material moving chain 32 continues to move and transport the second steel bar truss 10. When the second steel bar truss 10 moves to the second positioning plate 22 of the first positioning lifting assembly 2, it is blocked and positioned by the second positioning plate 22. At this time, the lifting drive 21 of the second positioning lifting assembly 2 drives the second positioning plate 22 to rise, and the material moving chain 32 continues to move and transport the third steel bar truss 10. When the third steel bar truss 10 moves to the second positioning plate 22 of the second positioning lifting assembly 2, it is blocked and positioned by the second positioning plate 22. Afterwards, the alignment plate 42 is driven by the alignment driving member 41 to move and align the ends of the three steel bar trusses 10 , thus completing the positioning process of the entire steel bar truss 10 .

[0047] The above-mentioned steel bar truss positioning mechanism of this embodiment can realize the precise positioning of multiple steel bar trusses 10, so that multiple steel bar trusses 10 are positioned and placed according to a preset spacing, with a high degree of automation, reducing the safety hazards of the labor intensity of operators and improving production efficiency and yield rate.
