Figure 1 and Figure 2 Provide explanation.

[0025] Some specific implementation modes described below are intended to facilitate those skilled in the art to understand the present embodiment, and the present embodiment is not limited to some specific implementation modes described below.

[0026] Reference Figure 1 and Figure 2 An exemplary embodiment of the present disclosure provides a modular belt deviation protection assembly test device, the modular belt deviation protection assembly test device comprising:

[0027] There are at least two correcting rollers 1 in a first state with their top ends close to each other in an inclined posture, and a protective area 7 for accommodating the belt is provided between the correcting rollers 1;

[0028] The controller 2 is fixed to at least one of the deflection correcting rollers 1 and is used to drive the top end of the deflection correcting roller 1 to move away from the other deflection correcting roller 1. The controller 2 has at least a power output end 22 and a power input end 23. The power input end 23 and the power output end 22 are respectively arranged on both sides of the protection area 7.

[0029] The elastic member 4 is fixed to the deflection-correcting roller 1 and is used to drive the deflection-correcting roller 1 to return to the first state.

[0030] For example, refer to Figure 1 and Figure 2 , further comprising a frame 3, the frame 3 comprising a first connecting frame 31 for supporting the deviation-correcting roller 1, a second connecting frame 32 for supporting the first connecting frame 31 and rotatably connected to the first connecting frame 31, and a third connecting frame 33 rotatably connected to the second connecting frame 32 and slidably connected to the first connecting frame 31, the rotation axes of the first connecting frame 31 and the third connecting frame 33 are parallel to each other, and the sliding direction of the third connecting frame 33 is perpendicular to the rotation direction of the third connecting frame 33. The second connecting frame 32 serves as a bearing base, one end of the first connecting frame 31 is hinged to the top of the second connecting frame 32, the other end of the first connecting frame 31 is hinged to the third connecting frame 33, one end of the third connecting frame 33 is hinged to the first connecting frame 31, and the other end of the third connecting frame 33 is hinged to the second connecting frame 32. Both the first connecting frame 31 and the third connecting frame 33 can rotate relative to the second connecting frame 32 along an axis extending in the horizontal direction, and the first connecting frame 31, part of the second connecting frame 32 and the third connecting frame 33 together form a stable triangular structure that is not easily deformed.

[0031] The first connecting frame 31 is provided with a first through slot 311 that penetrates the first connecting frame 31 along the direction of the rotation axis of the first connecting frame 31 and extends along the length direction of the first connecting frame 31. The first connecting frame 31 on one side of the first through slot 311 is also provided with a plurality of threaded holes that are spaced apart along the length direction of the first connecting frame 31. The third connecting frame 33 is provided with a second through slot 331 that penetrates the third connecting frame 33 along the direction of the rotation axis of the third connecting frame 33 and extends along the length direction of the third connecting frame 33. The second connecting frame 32 is provided with a plurality of threaded holes that penetrate the second connecting frame 32 in the horizontal direction and are spaced apart vertically. A bolt that is simultaneously threadedly connected to a threaded hole on the first connecting frame 31 is threadedly connected to another threaded hole on the first connecting frame 31 and is simultaneously inserted into the second through slot 331. A bolt that is simultaneously threadedly connected to a threaded hole on the second connecting frame 32 is also inserted into the second through slot 331. The aforementioned three bolts are all fixed by nuts. The user can change the posture and position of the correcting roller 1 connected to the first connecting frame 31 by selecting the first through groove 311 or the threaded hole on the first connecting frame 31 to connect with the second connecting frame 32, and fix the angle of the first connecting frame 31 by tightening the bolt with a nut. Similarly, the connection between the first connecting frame 31 and the third connecting frame 33 can also be used to change the posture and position of the correcting roller 1 in the above manner.

[0032] The deviation-correcting roller 1 includes a support rod 12 fixed to the first connecting frame 31 and a sleeve 11 coaxially connected to the support rod 12. The support rod 12 is made of an elastic material such as rubber, and the elastic member 4 is a spring. The spring is coaxially sleeved on the support rod 12. The support rod 12 is fixedly connected to the first connecting frame 31 and is perpendicular to the first connecting frame 31. The support rod 12 is also perpendicular to the rotation axis of the first connecting frame 31. The sleeve 11 is coaxially sleeved on the support rod 12 and is connected to the support rod 12 in a fixed-axis rotation manner. The top end of the spring is fixedly connected to the bottom end of the sleeve 11, and the bottom end of the spring is fixedly connected to the support rod 12. When the deviation-correcting roller 1 abuts against the belt, the sleeve 11 abuts against the belt and rotates with the moving belt, thereby reducing the friction between the belt and the deviation-correcting roller 1, reducing the belt loss, and applying a limit to the belt through the support rod 12 and the spring when the belt deviates to both sides, thereby correcting the belt.

[0033] The bottom end of the support rod 12 extends from the bottom end of the sleeve 11 and is fixedly connected to the first connecting frame 31. The top end of the support rod extends from the top end of the sleeve 11 and is fixedly connected to the fixing ring 13. The axis of the fixing ring 13 is parallel to the axis of the support rod 12. The controller 2 includes a connecting rope 21 with one end fixedly connected to a deviation correction roller 1. One end of the connecting rope 21 is wound around and fixed on the fixing ring 13. The other end of the connecting rope 21 is bent and extended to the bottom of another deviation correction roller 1. A pulley block 5 for supporting and tensioning the connecting rope 21 is fixed on the second connecting frame 32. The pulley block 5 includes a tension spring 51 fixed to the second connecting frame 32 and a fixed pulley 52 fixedly connected to the tension spring 51. One end of the tension spring 51 is fixedly connected to the second connecting frame 32, for example, it is hooked on the second connecting frame 32 and welded and fixed after the posture is determined, and the other end of the tension spring 51 is fixedly connected to the fixed pulley 52. ​​The connecting rope 21 is set up and supported and guided by the fixed pulley 52 and then extends to a position below another deviation correcting roller 1. The tension spring 51 can provide the fixed pulley 52 with the required displacement stroke. For example, after the posture of the deviation correcting roller 1 is changed to the extreme position by pulling the connecting rope 21, when the connecting rope 21 is continued to be pulled, the connecting rope 21 applies pressure on the fixed pulley 52, thereby further stretching the tension spring 51, causing the fixed pulley 52 to be displaced, thereby reducing the possibility of the connecting rope 21 being broken due to excessive pulling force. It should be understood that the pulley group 5 includes a tension spring 51 and a fixed pulley 52 , so a group of tension springs 51 must be provided, and multiple groups of fixed pulleys 52 can also be provided on the second connecting frame 32 to change the direction of the connecting rope 21 and support the connecting rope 21 .

[0034] The second connecting frame 32 includes a vertical beam 322 located at the deviation correction roller 1 and a horizontal beam 323 located at the protection area 7. A plurality of support rings 8 for sleeved with the connecting rope 21 are fixed on the horizontal beam 323. The support rings 8 are spaced apart along the length direction of the horizontal beam 323. The axis of the support ring 8 is parallel to the length direction of the horizontal beam 323. The pulley block 5 is located at the ends of the vertical beam 322 and the horizontal beam 323. The crossbeam 323 is fixed with a positioning hoop 6 for buckling the belt body and a positioning bolt 61 which is threadedly connected to the positioning hoop 6 and is used to press the positioning hoop 6 against the belt body. There are two positioning hoops 6 which are respectively arranged at both ends of the crossbeam 323. The two positioning hoops 6 are C-shaped and their openings are arranged opposite to each other. The positioning bolt 61 is threadedly connected to the positioning hoop 6. The positioning bolt 61 penetrates part of the solid body of the positioning hoop 6 from the bottom surface of the positioning hoop 6 and then extends into the C-shaped opening of the positioning hoop 6. After the positioning hoop 6 is buckled on the belt body, the positioning hoop 6 can be fixed at the current position on the belt body and maintain the current posture by tightening the positioning bolt 61, so that the deviation correction roller 1 can be separately arranged on both sides of the belt.

[0035] In this embodiment, the correcting roller 1 is arranged on the inner and outer sides of the belt, and the belt passes through the protection area 7. The controller 2 located on the outer side of the belt drives the correcting roller 1 located on the inner side of the belt to move to achieve the experimental purpose, and the correcting roller 1 is reset by the elastic member 4 to meet the needs of a new round of experiments.

[0036] In an exemplary embodiment of the present disclosure, referring to Figure 1 and Figure 2 The correcting roller 1 is slidably connected to the first connecting frame 31 , and the sliding direction of the correcting roller 1 is perpendicular to the rotation direction of the third connecting frame 33 , and is set at an angle with the sliding direction of the third connecting frame 33 .

[0037] For example, refer to Figure 1 and Figure 2 The bottom end of the support rod 12 is fixedly connected with a mounting frame 14, and the mounting frame 14 is fixed to the first connecting frame 31 by two bolts passing through the first through slot 311. The bottom end of the spring is fixedly connected to the mounting frame 14. By loosening the nut on the bolt, the mounting frame 14 can slide along the length direction of the first through slot 311, thereby changing the posture and position of the deviation correction roller 1.

[0038] The present invention is capable of being implemented or used by those skilled in the art. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
