[0007] Further preferably, the connecting shaft is a bolt, the bolt penetrates through the side of the overlapping part horizontally to connect the side support column and the side support in series, and the side support column can rotate around the bolt; the bolt is stably connected by a stop nut.

[0008] Further preferably, the side support and the side support column are both of groove structure, and the groove parts of the two are both directed to the outside; the bottom of the side support column is located between the two connecting lugs.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] Example 1: As Figures 1 to 5 The diagram shows a folding idler beam for a belt conveyor, comprising a beam body 1 that supports the entire idler assembly. Side supports 2 are located at both ends of the beam body 1, and are perpendicularly fixed to the beam body 1. The side supports 2 are integrally connected to the beam body 1 or welded together. Side support columns 3 are connected to each of the two side supports 2, extending upwards along the length of the side supports 2. The side support columns 3 support the side rollers of the idler assembly. When packaging and transporting the idler beam, the side support columns 3 are folded and retracted along their connection points with the side supports 2.

[0029] Since the side support 3 can be folded and retracted along the connection with the side support 2, the height of the entire idler beam can be greatly reduced after the side support 3 is folded and retracted, making the overall structure of the idler beam more balanced, making it easier to package and stack, reducing the space occupied during warehousing and transportation, and reducing packaging costs, transportation costs and storage costs.

[0030] Example 2: Based on Example 1, the connection method between the upper side support 2 and the side support column 3 is optimized. Connecting ears 21 are fixed to both sides of the top of the side support 2. The connecting ears 21 are plate-shaped structures and integrally connected to the side support 2. The two connecting ears 21 stand opposite each other. The bottom sides of the side support column 3 are parallel to the two connecting ears 21 and form overlapping portions 4 with them. Two connecting shafts 41 pass horizontally through the overlapping portions 4, and the side support column 3 can rotate around the connecting shafts 41. Therefore, when the idler beam needs to support and convey materials, such as... Figure 5 As shown, the side support 3 is flipped upwards until it is perpendicular to the crossbeam body 1, at which point the side roller can be placed on the side support 3; and when it is necessary to transport or store the idler crossbeam, as... Figure 4As shown, the side support column 3 is flipped down, the height of the side support column 3 is lowered, the height of the whole roller beam is reduced, the height of the roller beam can be reduced without the side support column 3 completely leaving the roller beam, the structure can also reduce the amount of subsequent installation engineering, and the assembly efficiency is improved.

[0031] Specifically, the connecting shaft 41 is selected as a bolt 5, the two overlapping parts 4 are connected through the bolt 5, the bolt 5 passes through the side of the overlapping part 4 horizontally to connect the side support column 3 and the side support base 2 in series, the side support column 3 can rotate around the bolt 5, and the bolt 5 is stably connected through a stop nut 51, that is, the movable end of the bolt 5 is connected with the stop nut 51, the stop nut 51 can prevent the bolt 5 from loosening or falling off when subjected to vibration or load, thereby ensuring the stability and safety of the connecting structure, preventing the bolt 5 from loosening, and affecting the support stability of the whole roller beam. In use, the side support column 3 can be controlled and fixed by tightening or loosening the stop nut 51, and the side support column 3 can be flipped.

[0032] Preferably, the outer sides of the side support base 2 and the side support column 3 are both recessed inward to form a groove-shaped structure, which reduces the weight of the whole roller beam and maintains the support strength of the whole roller beam. The bottom of the side support column 3 is located between the two connecting ears 21, and the two sides are attached to the connecting ears 21, so that the width of the side support column 3 is less than the width of the side support base 2, thereby reducing the bearing pressure of the side support base 2. The bottom surface of the side support column 3 is higher than the top surface of the side support base 2 (not the connecting ear 21), which increases the flipping range of the side support column 3, and avoids the side support column 3 from being folded and overlapped on the beam body 1.

[0033] Preferably, the side support base 2 and the side support column 3 are further connected through a fixed plate 6, the fixed plate 6 is fixed parallel to the inner side surfaces of the side support base 2 and the side support column 3, two mounting holes 61 are formed in the fixed plate 6, the positions of the two mounting holes 61 correspond to the positions of the mounting holes 61 on the side support base 2 and the side support column 3 one by one, and the fixed plate 6 is fixedly connected with the side support base 2 and the side support column 3 through the bolt 5. The bolt 5 passes through the mounting holes 61 of the side support base 2 and the corresponding mounting holes 61 of the fixed plate 6 to fix the fixed plate 6 on the side support base 2, and the bolt 5 passes through the mounting holes 61 of the side support column 3 and the corresponding mounting holes 61 of the fixed plate 6 to fix the fixed plate 6 on the side support column 3. The fixed plate 6 is arranged to connect the side support base 2 and the side support column 3 to improve the stability and support strength of the connection between the two. The bolt 5 is stably connected through the stop nut 51 to prevent the bolt 5 from loosening and affecting the support stability of the whole roller beam. When the roller beam needs to support the material conveying, the fixed plate 6 is kept fixedly connected with the side support base 2 and the side support column 3, and when the roller beam needs to be transported or stored, only the bolt 5 connected with the side support column 3 on the fixed plate 6 needs to be disassembled. At this time, the fixed plate 6 is also installed on the side support base 2, which reduces the amount of subsequent installation engineering and improves the assembly efficiency.

[0034] In the above embodiment, the side support 3 is folded inwardly to the inner side of the side support 2, and the movable end of the side support 3 is connected to the surface of the beam body 1. By folding the side support 3 to the side support 2, the height of the roller beam is reduced without increasing the length of the roller beam, thereby further reducing the occupied space of the roller beam and facilitating packaging and transportation.

[0035] In the above embodiment, the side support 3 is folded inwardly to the inner side of the side support 2, and the movable end of the side support 3 is connected to the surface of the beam body 1. By folding the side support 3 to the side support 2, the height of the roller beam is reduced without increasing the length of the roller beam, thereby further reducing the occupied space of the roller beam and facilitating packaging and transportation.

[0036] Further, the height of the side support 3 is less than the distance between the middle support 7 and the adjacent side support 2, so as to avoid the side support 3 from being folded on the middle support 7 and increasing the occupied area of the roller beam.

[0037] In the packaging and transportation of the roller beam, the fixed plate 6 is first installed on the side support 2 through the bolt 5, and the bolt 5 is pre-tightened by the stop nut 51, i.e., the bolt 5 is tightened to just enable the rotation of the fixed plate 6. Then, the two side supports 3 are installed in the connecting ears 21 of the two side supports 2 through the bolts 5, and the bolts 5 are pre-tightened by the stop nuts 51, i.e., the bolts 5 are tightened to just enable the rotation of the side supports 3. The two side supports 3 are folded inwardly around the bolts 5 to contact the surface of the roller beam. Finally, the folded roller beam is packaged and transported, thereby greatly saving the occupied space and reducing the packaging cost, transportation cost and storage cost. Since the fixed plate 6 and the side support 3 are only pre-tightened during transportation, the time for loosening the stop nuts 51 in the fully tightened state during the subsequent assembly of the roller beam on site is greatly saved. After pre-tightening, the fixed plate 6 and the side support 3 will not be separated from the roller beam, and the subsequent assembly of the roller beam is facilitated, thereby reducing the assembly time and improving the assembly efficiency.

[0038] The above embodiments only express the specific implementation of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the protection scope of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the technical concept of the present application, a number of modifications and improvements can be made, which are within the protection scope of the present application.
