Technical Field

[0001] The utility model relates to the field of belt conveyors, in particular to a device for facilitating replacement of a driving roller of a belt conveyor. Background Art

[0002] With the continuous advancement and innovation of industrial technology, belt conveyor drive rollers, as core components of conveyor belt equipment, have undergone continuous updates and improvements. Based on traditional belt conveyor drive rollers, with the development of science and technology and production processes, new belt conveyor drive rollers have emerged, offering many advantages such as higher production efficiency, more stable performance, lower energy consumption, and longer service life.

[0003] In the wet-process phosphoric acid production process, the transportation of phosphate rock and phosphogypsum relies on belt conveyors. When a belt conveyor's drive roller fails, the system must be shut down for replacement. The longer the replacement time, the greater the loss of production. Traditional conveyor drive roller replacement methods require significant manual effort, which is time-consuming and poses safety risks. Therefore, shortening replacement time and improving the safety and efficiency of the replacement process have become urgent challenges.

[0004] However, when replacing the drive roller, it is generally necessary to fix the belt to prevent the belt from retracting. Traditional drive roller replacement not only takes a lot of time, but also requires a lot of manpower. Utility Model Content

DETAILED DESCRIPTION

[0023] like Figure 1-7 As shown, an embodiment of the present application provides a device for facilitating replacement of a belt conveyor drive roller, comprising a base 12 arranged below the movement path of a conveyor 101, and a belt clamping device 1 arranged above the base 12; the belt clamping device 1 comprises a support member 2 arranged between two layers of belts for supporting an upper belt 102 and a lower belt 103, a third support shaft 11 arranged on the base 12, and a linear propulsion mechanism 3 arranged on the upper and lower sides of the third support shaft 11 for pressing the belt to the support member 2.

[0024] The belt clamping device 1 is arranged next to the driving roller of the conveyor 101. When the driving roller needs to be removed, the belt clamping device 1 is started to fix the positions of the upper belt 102 and the lower belt 103. Only the upper belt 102 or the lower belt 103 can be fixed to achieve the function of fixing the belt, thereby completing the preliminary work for removing the driving roller.

[0025] In a preferred embodiment, the linear propulsion mechanism 3 includes a support plate 31 disposed on the third support shaft 11, a cylinder 32 disposed on the support plate 31, a connecting seat 33 disposed on the shaft extending from the cylinder 32, and a pressure plate 34 disposed on the connecting seat 33. By placing the support member 2 between the upper belt 102 and the lower belt 103, the linear propulsion mechanism 3 moves to one side, and the pressure plate 34 presses the upper belt 102 and the lower belt 103 against the surface of the support member 2, thereby fixing the upper belt 102 and the lower belt 103. The pressure plate 34 can be made of plastic to avoid damaging the belts.

[0026] In a preferred embodiment, a linear bearing 35 is further provided on the support plate 31, and a guide shaft 36 is sleeved in the linear bearing 35. One end of the guide shaft 36 is connected to the pressure plate 34. When the pressure plate 34 moves along the direction of the guide shaft 36, it can resist a certain lateral force.

[0027] In a preferred embodiment, a mounting plate 13 is provided on the base 12, a mounting hole 131 is provided in the mounting plate 13, the third support shaft 11 is inserted into the mounting hole 131, and a fixing ring 4 is provided on the third support shaft 11 to fix the third support shaft 11 to the mounting plate 13.

[0028] In a preferred embodiment, the fixing ring 4 includes a first through-hole 41 for fitting the third support shaft 11. Slots 42 are provided on both sides of the first through-hole 41. The slots 42 divide the fixing ring 4 into two parts. A threaded hole 43 is provided on a vertical surface on one side of the slot 42 of the fixing ring 4, and a second through-hole 44 is provided on a vertical surface on the other side of the slot 42 of the fixing ring 4. The two parts of the slot 42 are connected by screws installed in the threaded hole 43 and the second through-hole 44. A fastening hole 45 is provided on the upper surface of the fixing ring 4 for connecting the fixing ring 4 to the mounting plate 13. By tightening the screws, the third support shaft 11 can be tightly clamped, and by installing screws in the fastening holes 45, the fixing ring can be fixed to the mounting plate 13.

[0029] In the preferred solution, the support member 2 includes an upper plate 21 and a lower plate 22, a first support shaft 23 is provided below the upper plate 21, a second support shaft 24 corresponding to the first support shaft 23 is provided above the lower plate 22, and an adjusting member 25 is provided between the first support shaft 23 and the second support shaft 24.
