DETAILED DESCRIPTION

[0028] Please refer to Figures 1 to 3The present application provides an adjustable lower roller hanger assembly 1, hereinafter referred to as this assembly, which includes two hangers 11 and a single roller 12. Figure 2 As shown, the end of the hanger 11 is bent to form an open slot 111. The hanger 11 also has a slot 112, which is spaced apart from the open slot 111 and is used to pass the roller 12. The two ends of the roller 12 are respectively locked in the slots 112 of the two opposite hangers 11, thereby achieving the assembly of the roller 12 on the hanger 11, and supporting the lower belt of the belt conveyor 2 via the roller 12.

[0029] The belt conveyor 2 is provided with a frame, and the frame is provided with two opposite main beams 21. The two hangers 11 in this assembly are respectively suspended on the two opposite main beams 21 of the belt conveyor 2 through the open slots 111, and the hangers 11 and the main beams 21 are clearance-fitted, and the clearance of the clearance fit is controlled within a range of less than or equal to 0.5 mm, thereby ensuring that the connection between the hangers 11 and the main beams 21 is relatively precise, ensuring that the hangers 11 suspended on the main beams 21 will not shake, and the position of the hangers 11 on the main beams 21 can be adjusted using tools.

[0030] When the belt conveyor 2 has a deviation problem, especially when the deviation problem cannot be solved by the deviation adjustment roller frame group of the belt conveyor 2, this component is installed on the belt conveyor 2. Specifically, the two hangers 11 of this component are hung on the two opposite main beams 21 of the belt conveyor 2, and the rollers 12 are clamped in the clamping grooves 112 of the two hangers 11. The lower belt body of the belt conveyor 2 is supported by the rollers 12, so that the hanger 11 and the main beam 21 are clearance-matched and the clearance of the clearance is controlled within 0.5mm; then, the staff can use tools such as a hammer to slightly move the hanger 11 along the length direction of the main beam 21, adjust the contact position of the lower belt body of the belt with the rollers 12 of this component, thereby realizing the adjustment of the running position of the belt, and through multiple adjustments and corrections until the deviation problem of the belt conveyor 2 is solved, the foundation is laid for the long-term stable operation and smooth production of the belt conveyor 2.

[0031] This component can be used to adjust the belt without stopping the belt conveyor 2, and can complete the deviation adjustment process without stopping the belt conveyor 2, thereby adding a short-term effective emergency device to the belt conveyor 2, avoiding the problem of reduced production efficiency due to the belt conveyor 2 stopping for deviation correction.

[0032] Please refer to Figure 4 When the belt conveyor 2 has a deviation problem, especially when the deviation problem cannot be solved by the deviation adjustment roller frame group of the belt conveyor 2, two or more of the components can be used in combination to adjust the belt of the belt conveyor 2 together.

[0033] like Figure 4As shown, this assembly is installed between two adjacent groups of upper rollers 23. Figure 4 The lower roller structure of belt conveyor 2 is not shown in the figure, so no adjustments are required when installing this component. In addition, if the lower roller of belt conveyor 2 is damaged and the machine cannot be shut down for replacement, this component can be installed on the main crossbeam 21 of belt conveyor 2. The roller 12 of this component can replace the damaged lower roller of belt conveyor 2, allowing for short-term emergency use, laying a reliable foundation for the long-term stable operation of belt conveyor 2.

[0034] Please refer to Figure 4 Protective panels 22 are often arranged on both longitudinal sides of the conveyor belt 2. These panels are typically mesh-like structures. When the conveyor belt 2 is in operation, these panels reduce the risk of personnel coming into contact with the rotating area of the conveyor belt 2, thereby improving personal safety. The protective panels 22 are typically detachably connected to the main beam 21. During maintenance or other non-operational periods, the protective panels 22 can be removed from the main beam 21.

[0035] In some embodiments, see Figure 4 The protective sheet 22 defines a vertically extending escape zone 221. This escape zone 221 allows the hanger 11 of this assembly to be smoothly suspended from the main beam 21. During use of this assembly, the hanger 11 can be slightly moved along the length of the main beam 21 using a tool. Therefore, the escape zone 221 also needs to take into account the distance the hanger 11 moves along the length of the main beam 21. In actual use, given the relatively short distance the hanger 11 moves along the length of the main beam 21, the width of the escape zone 221 is generally set to no more than 200 mm.

[0036] In some embodiments, see Figure 2 The slot 112 passes through the hanger 11 along the thickness direction 1131 of the hanger 11, and please refer to Figure 3 The slot 1121 of the clamping groove 112 is located on the length side of the hanger 11. Specifically, the slot 1121 is provided on the side of the hanger 11 in the thickness direction and the length direction. With this method, the roller 12 can smoothly pass through the slot 1121 and enter the clamping groove 112, completing the assembly process of the roller 12 to the hanger 11, making the assembly process of the roller 12 to the hanger 11 more convenient.

[0037] In some other embodiments, the slot 112 may not form the notch 1121 on the side where the thickness of the hanger 11 is located. However, compared with the method in which the slot 112 forms the notch 1121 on the side where the thickness of the hanger 11 is located, this method has a disadvantage when disassembling and assembling the roller 12.

[0038] In some embodiments, please refer to Figure 2 and Figure 3The slot 112 extends through the hanger 11 along its thickness direction 1131. The slot 112 is tilted relative to the width direction 1132 of the hanger 11. One end of the slot 112 forms a notch 1121 in the hanger 11 along its width direction 1132. The other end of the slot 112 forms a groove bottom 1122 in the hanger 11 along its width direction 1132. The groove bottom 1122 is further away from the opening 111 than the notch 1121. When the roller 12 smoothly enters the slot 112 through the notch 1121, the roller 12 smoothly falls to the groove bottom 1122 and remains stationary there, based on the tilted arrangement of the slot 112. In some embodiments, the slot 112 is tilted at a 45° angle relative to the width direction 1132 of the hanger 11. Through the above method, the difficulty of clamping the roller 12 in the clamping groove 112 is simplified, the structural simplicity of the component is maintained, and the installation convenience of the component is improved.

[0039] In some embodiments, see Figure 2 The hanger 11 is provided with at least two slots 112 , and the direction from the opening slot 111 to the direction away from the opening slot 111 is the length direction 1133 of the hanger 11 . Figure 2 The longitudinal direction 1133 of the hanger 11 is shown. When the hanger 11 is installed on the belt conveyor 2, the longitudinal direction 1133 of the hanger 11 is vertical, and at least two slots 112 are arranged in sequence along the longitudinal direction 1133 of the hanger 11. By selecting the position of the slots 112 through which the roller 12 passes, the roller 12 can be adjusted vertically. Combined with the forward and backward movement of the hanger 11 when the tool is used to slightly shift the hanger 11 along the longitudinal direction of the main crossbeam 21, the roller 12 can be adjusted forward and backward, up and down as a whole, thereby improving the ability of this component to adjust the deviation of the lower belt body of the belt. In actual applications, the number of slots 112 opened by the hanger 11 is usually controlled to be 4-6, and the distance between two adjacent slots 112 is controlled to be about 50 mm.

[0040] Regarding the movement process of the roller 12 from the slot 112 at one height to the slot 112 at another height, in some embodiments, at least two sleeves 13 are provided in this component, and the above-mentioned movement process is facilitated by the sleeves 13. Specifically, the two sleeves 13 are sleeved on both ends of the length of the roller 12. The staff on one side of the belt conveyor 2 first moves one end of the roller 12 from the slot 112 at one height to the slot 112 at another height through the sleeve 13 on that side. After the staff on that side has completed the operation, the staff on the other side of the belt conveyor 2 moves the other end of the roller 12 from the slot 112 at one height to the slot 112 at another height, so that the roller 12 passes through the slot 112 at the same height, thereby completing the movement process of the roller 12 from the slot 112 at one height to the slot 112 at another height.

[0041] In some embodiments, see Figure 2 The hanger 11 includes a main plate 1141, a top plate 1142, and a sub-plate 1143. The main plate 1141 defines a slot 112. One end of the top plate 1142 is connected to the main plate 1141, and the other end of the top plate 1142 is connected to the sub-plate 1143. The sub-plate 1143 is aligned with and parallel to the main plate 1141. The sub-plate 1143, top plate 1142, and main plate 1141 together form an open slot 111. The main plate 1141 is longer than the sub-plate 1143, thereby spacing the slot 112 on the main plate 1141 from the open slot 111. In some embodiments, the main plate 1141 is 200 mm to 400 mm long, and the sub-plate 1143 is 120 mm to 150 mm long.

[0042] In some embodiments, the main plate 1141, top plate 1142, and sub-plate 1143 are all made of steel plates. The main plate 1141 and top plate 1142, and the sub-plate 1143 can be fixedly connected by welding, and the top plate 1142 and sub-plate 1143 can be fixedly connected by welding, specifically by full welding. In some embodiments, the thickness of the steel plates is 8 mm to 10 mm.

[0043] In some embodiments, see Figure 1 The roller 12 includes a main roller 121 and an extension shaft 122. The main roller 121 includes a roller shaft and a roller rotatably sleeved on the roller shaft. The roller is used to support the lower belt body. Two extension shafts 122 are arranged opposite to each other. The two extension shafts 122 are respectively connected to the two ends of the roller shaft. The two extension shafts 122 are used to be respectively clamped in the clamping grooves 112 of the two hangers 11. The main roller 121 can usually use the old roller 12 belonging to the belt conveyor 2. The two extension shafts 122 are respectively welded to the two ends of the main roller 121. Usually, the diameter of the extension shaft 122 is smaller than the outer diameter of the roller of the main roller 121. After the deviation problem of the belt conveyor 2 has been solved by this component, as the belt runs, the roller of the main roller 121 rotates with the belt, and the extension shaft 122 and the roller shaft of the main roller 121 remain stationary.

[0044] In the solution where the roller 12 includes a main roller 121 and an extension shaft 122 , when this component is designed with a sleeve 13 , the two sleeves 13 are detachably sleeved on the extension shaft 122 , and the staff holds the sleeve 13 to move the roller 12 from one slot 112 to another slot 112 .

[0045] The present application also provides a belt conveyor 2, which includes a main body and at least one of the above-mentioned adjustable lower roller hanger assemblies 1. The main body is provided with a frame, the main body is provided with rollers mounted at both ends of the frame, the main body is provided with multiple upper rollers 23 and multiple lower rollers located between the rollers, the main body is provided with a belt sleeved on the sleeve, the upper rollers 23 and the lower rollers, and the frame is provided with two opposing main beams 21; the adjustable lower roller hanger assembly 1 is provided with two hangers 11 and a single roller 12, the two hangers 11 of this assembly are hung on the two main beams 21, and the lower belt body of the belt is supported by the roller 12.
