Therefore, the operation steps are cumbersome, and a large number of processes require manual driving operations, which are time-consuming and laborious. Moreover, after the new idler is installed, it is necessary to ensure that both ends of the idler can be tightly embedded in the top groove of the idler frame by knocking, which is difficult and easy to damage both ends of the idler during the knocking process.

[0022] To make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further elaborated below in conjunction with specific embodiments.

[0023] Please refer to Figures 1 to 4 , the present utility model provides the following technical solutions: An idler roller replacement auxiliary device, including an auxiliary device body, an idler roller frame 1 and a belt 2, the auxiliary device body includes a transfer rack 3, a disassembly and assembly mechanism 4 and a positioning component 5, the top of the idler roller frame 1 is embedded with an idler roller, the belt 2 is placed on the top of the idler roller, the transfer rack 3 includes a bottom plate 6 and a side plate 7, the positioning component 5 is placed on the surface of the bottom plate 6, the disassembly and assembly mechanism 4 is installed on the top of the positioning component 5, and the top of the disassembly and assembly mechanism 4 is integrally formed with a top plate 18, and the top of the top plate 18 is used to jack up the bottom of the belt 2. This idler roller replacement auxiliary device is used to remove the old idler roller on the idler roller frame 1 and directly place the new idler roller on the idler roller frame 1 after removal.

[0024] When the utility model is in use, first push the device to the bottom of the belt 2 through the transfer rack 3 at the bottom and close to one side of the idler to be replaced, as Figure 1 shown. Then, lift the belt 2 by means of the pneumatic and electric lifting rod 11. At this time, use the disassembly and assembly mechanism 4 to lift the old idler on the idler bracket 1, and then control the transfer rack 3 to move back again. After lowering, the old idler can be directly taken out. At this time, control the electric lifting rod 11 to lift again until the disassembly and assembly mechanism 4 is aligned with the installation area on the idler bracket 1. Insert the new idler into the interior of the disassembly and assembly mechanism 4 from the surface of the side plate 7. After starting the positioning component 5, unlock the placed new idler, and the idler can be moved onto the idler bracket 1 under the guidance of the disassembly and assembly mechanism 4. Finally, contract the electric lifting rod 11, and apply a downward pressure to the installed idler by means of the lowering effect to ensure that the new idler can be fully installed.

[0025] In this embodiment, the electric lifting rod 11 is screwed on the surface of the bottom plate 6. A pushing hole 8 is opened in the middle of the side plate 7. A pushing channel 9 is integrally formed on the outer side of the side plate 7. The side plate 7 and the bottom plate 6 are in a right-angled bending state. A roller 10 is inserted at the bottom of the bottom plate 6. The number of the electric lifting rods 11 is two, and the top end of each electric lifting rod 11 is fixedly connected to the bottom of the disassembly and assembly mechanism 4. The inner wall diameter of the pushing hole 8 is the same as the surface diameter of the idler to be replaced.

[0026] Specifically, through the roller 10 at the bottom, the entire transfer rack 3 can be directly controlled to move. In the subsequent processes of lifting and removing the old idler and transporting and pressing the new idler, the entire transfer rack 3 needs to be pulled to complete.

[0027] In this embodiment, the disassembly and assembly mechanism 4 includes an arc-shaped plate 17 and a top plate 18. The top plate 18 is integrally formed on the top of the arc-shaped plate 17. A guiding inclined plate 22 is integrally formed at the bottom end of the arc-shaped plate 17. A strip-shaped hole 23 is opened on the surface of the guiding inclined plate 22. An extension plate 19 is integrally formed on the side of the top plate 18. A pressing groove 20 is arranged at the bottom of the extension plate 19. A lifting groove 21 is arranged on the side of the pressing groove 20. The surface of the extension plate 19 is flush with the surface of the top plate 18.

[0028] Specifically, in the initial state, after being moved by the transfer rack 3 to the side close to the old idler to be disassembled, the lifting groove 21 is moved to the bottom of the old idler. At this time, the electric lifting rod 11 is directly started until the lifting groove 21 abuts against the bottom of the old idler, and the old idler is taken out by lifting it upward. When installing the new idler subsequently, after aligning the guiding inclined plate 22 with the top of the idler rack 1 from which the old idler has been removed, the new idler is directly inserted into the pushing hole 8 from the pushing channel 9 until it is pushed into the inside of the arc plate 17. At this time, it will be blocked by the positioning stop rod 16. After removing the support of the positioning stop rod 16, the new idler can be rolled along the guiding inclined plate 22 into the top groove of the idler rack 1. Finally, the electric lifting rod 11 is directly controlled to move downward at this position, so that the pressing groove 20 at the top can be pressed downward on the top of the idler in place, and a downward pressure is applied to ensure complete embedding on the idler rack 1.

[0029] In this embodiment, the ends of the top plate 18 and the arc plate 17 abut against the inner wall of the side plate 7. The inner wall radian diameter of the arc plate 17 is the same as the surface diameter of the idler to be replaced. The pressing groove 20 and the lifting groove 21 are both of an arc structure as a whole. The end of the guiding inclined plate 22 is inclined downward. The positioning assembly 5 includes a cylinder 12 and a positioning stop rod 16. The cylinder 12 is fixed on the surface of the bottom plate 6. One end of the cylinder 12 is connected with a pressure pipeline 13. The top of the pressure pipeline 13 is sleeved with a lifting sleeve 14. An air-driven lifting rod 15 is inserted into the inside of the lifting sleeve 14. The top of the air-driven lifting rod 15 is welded with a positioning stop rod 16. The positioning stop rod 16 passes through the inside of the strip-shaped hole 23 as a whole. The top of the lifting sleeve 14 is welded at the bottom position of the arc plate 17.

[0030] Specifically, after the new idler is placed on the arc plate 17, due to being blocked by the positioning stop rod 16, even if the guiding inclined plate 22 at the bottom is in an inclined state, it will not directly roll downward but remain in a horizontal state. Subsequently, the cylinder 12 is started, and the lifting rod is moved downward and retracted into the inside of the lifting sleeve 14, and then the positioning stop rod 16 can be driven to move downward to release the blocking effect on the new idler. At this time, it can be ensured that the idler rolls downward evenly along the guiding inclined plate 22 while maintaining a horizontal state.

[0031] The above shows and describes the basic principles, main features and advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the present invention.

[0032] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
