[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1 - 8 , the present invention provides two technical solutions, specifically including the following embodiments:

[0033] Embodiment 1: In the embodiment of the present invention, a sprocket shaft group test mechanism for a scraper conveyor includes a body 1. A carrier disk frame 5 is slidably connected to the top surface of the body 1 for conveying the sprocket shaft group body 11. During the test, first, the sprocket shaft group body 11 is placed above the carrier disk frame 5 by means of hoisting or handling, and then the carrier disk frame 5 is operated to convey the sprocket shaft group body 11 to the position to be tested;

[0034] In the embodiment of the present invention, further, a concave detection frame 8 is slidably connected inside the body 1, and locking ends 12 are provided at both ends of the concave detection frame 8. The locking ends 12 are used to lock both ends of the conveyed sprocket shaft group body 11 and drive the locked sprocket shaft group body 11 to run to realize the test operation. When the carrier disk frame 5 conveys the sprocket shaft group body 11 to the position to be tested, by approaching the sprocket shaft group body 11 with the locking end 12 on one side, the clamping operation of both ends of the sprocket shaft group body 11 can be realized through the two locking ends 12, and then the clamped sprocket shaft group body 11 is rotated by the rotation of the locking end 12 to realize the detection operation;

[0035] In an embodiment of the present invention, a detection module is provided inside the concave detection frame 8. The detection module includes a rotational speed detection unit, an eccentric angle detection unit, a temperature detection unit, and a stability detection unit. The detection module is an existing device and is controlled based on a PLC control module, so no further description will be given here;

[0036] In an embodiment of the present invention, specifically, one end of the concave detection frame 8 is rotatably connected to a transmission collar 13. The locking end 12 is slidably connected inside the transmission collar 13, and the other locking end 12 is rotatably connected to the end of the concave detection frame 8 away from the transmission collar 13. The two locking ends 12 always remain coaxial. The transmission collar 13 is used to perform a driving operation. When the locking end 12 located inside the transmission collar 13 slides towards the sprocket shaft group body 11 until the sprocket shaft group body 11 is clamped, by rotating the transmission collar 13, it can drive the locking end 12 and the clamped sprocket shaft group body 11 to operate, realizing the detection operation of the parameters during the operation of the sprocket shaft group body 11;

[0037] In an embodiment of the present invention, further, a driving end 201 is rotatably connected inside the machine body 1. A driving belt 202 is rotatably connected between the driving end 201 and the transmission collar 13. The driving belt 202 is an existing device and is used to perform a transmission operation, and can be used to drive the transmission collar 13 to rotate inside the concave detection frame 8;

[0038] In an embodiment of the present invention, specifically, when the driving end 201 operates, it can drive the transmission collar 13 to rotate inside the concave detection frame 8 through the cooperation of the driving belt 202, realizing the driving operation;

A driving cylinder 3 is installed outside the machine body 1. The piston end of the driving cylinder 3 is installed with a rotating end 301, and the rotating end 301 is rotatably connected to the corresponding locking end 12. The rotating end 301 is used to drive the corresponding locking end 12 to slide inside the transmission collar 13, so that the clamping operation is completed during the process of the locking end 12 sliding towards the sprocket shaft group body 11;

[0040] In an embodiment of the present invention, specifically, a positioning notch 1201 is provided inside the locking end 12.

When the locking end 12 slides towards the sprocket shaft group body 11, as both ends of the sprocket shaft group body 11 enter the positioning notch 1201 provided inside the locking end 12 until the end of the sprocket shaft group body 11 contacts the inner wall of the positioning notch 1201, through the cooperation of the plurality of locking convex shafts 1202, the locking operation of the sprocket shaft group body 11 can be completed. At the same time, by shaping the positioning notch 1201 into a conical shape, it can be applicable to clamping operations on sprocket shaft group bodies 11 of different sizes. At the same time, during the clamping and locking process, the calibration of the sprocket shaft group body 11 can be automatically completed, so that the sprocket shaft group body 11 can be coaxial with the locking ends 12 on both sides;

[0041] In an embodiment of the present invention, specifically, a test chain 10 is provided inside the machine body 1 for connecting to the sprocket shaft group body 11 during the test. A detection rod 9 is rotatably connected inside the machine body 1. A test sprocket 901 is fixedly sleeved on the outer side of the detection rod 9.

[0044] In an embodiment of the present invention, specifically, a push cylinder 4 is fixedly installed inside the machine body 1. The piston end of the push cylinder 4 is fixedly connected to the concave detection frame 8 for driving the concave detection frame 8 to slide inside the machine body 1. The push cylinder 4 is a conventional device;

[0045] In an embodiment of the present invention, further, a limiting component is provided at the bottom of the carrier tray rack 5 for adjusting the height of the carrier tray rack 5. By adjusting the height of the carrier tray rack 5, it can be made suitable for transporting sprocket shaft group bodies 11 of different sizes, so that after the sprocket shaft group body 11 reaches the position to be measured, it can be coaxial with the locking ends 12 on both sides, further improving the clamping stability;

[0046] In an embodiment of the present invention, specifically, the limiting component includes a limiting plate rack 6.

An adjusting cylinder body 502 is fixedly installed inside the machine body 1, and a telescopic sleeve plate 5021 is rotatably installed at the piston end of the adjusting cylinder body 502. The telescopic sleeve plate 5021 is installed at the bottom of the carrier tray rack 5;

[0047] In an embodiment of the present invention, the thread adjusting sleeve rod 602 is a conventional device, that is, adjusting rods are threadedly connected to both ends of a hollow sleeve. The ends of the two adjusting rods are respectively rotationally connected to the machine body 1 and the limiting plate rack 6. When the hollow sleeve is rotated forward or backward, the adjusting rods at both ends can be stretched or retracted under force, realizing the adjustment of the installation inclination of the limiting plate rack 6, so that the height of the carrier tray rack 5 is convenient to adjust when sliding to the position to be measured, and thus it can be suitable for transporting sprocket shaft group bodies 11 of different sizes;

[0048] In an embodiment of the present invention, specifically, a limiting shaft 601 is rotatably connected to one end of the limiting plate rack 6 away from the thread adjusting sleeve rod 602. The limiting shaft 601 is rotatably connected to the machine body 1.

[0049] Embodiment 2: Based on Embodiment 1, on the basis of Embodiment 1; a protection component is provided inside the machine body 1 for stretching during the test of the sprocket shaft group body 11 to achieve protection operations; the protection component includes a protection plate rack 7. The protection plate rack 7 is fixed inside the machine body 1. An inner protection plate 701 is slidably connected inside the protection plate rack 7. A transmission shaft 703 is rotatably connected inside the machine body 1. A transmission gear 704 is fixedly sleeved on the outer side of the transmission shaft 703. A transmission belt 705 is rotatably connected between the end of the transmission shaft 703 and the driving end 201. A transmission tooth plate 702 is fixedly installed at the bottom of the protection plate rack 7. The transmission gear 704 meshes with the transmission tooth plate 702;

[0050] In the embodiment of the present invention, specifically, the length of the transmission gear 704 is two-thirds of that of the inner protection plate 701, that is, when the transmission gear 704 operates, it can drive the protection plate frame 7 to slide outwards through the transmission tooth plate 702 to achieve protection until the transmission gear 704 moves to the end of the transmission tooth plate 702 and idles. At this time, the inner protection plate 701 is stationary, and the operation safety of the equipment can be effectively improved by the extension of the inner protection plate 701;

[0051] In the embodiment of the present invention, the protection plate frame 7 and the inner protection plate 701 always remain parallel, and a plurality of springs for resetting are installed between the end of the inner protection plate 701 and the inside of the protection plate frame 7. After the operation is completed, by reversing the transmission shaft 703, the inner protection plate 701 can be retracted into the protection plate frame 7 through the cooperation of the springs.

[0052] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
