[0015] Beneficial effects

[0016] According to the test devices of the embodiments of the present invention, the tests are more comprehensive, adjustable floating drive can be achieved, the overall linkage is stronger, heating and scratching tests can be assisted, and the belt test is more standard.

[0017] In addition, by setting a floating test piece and cooperating with the provided propulsion detection device, comprehensive detection of the belt can be achieved, the practicability is stronger, the problem of incomplete detection of belt vibration can be effectively avoided, dynamic fixed-point tests on the side and outer periphery of the belt can be realized, the use is more flexible and stable, the data is more accurate, the overall structure is more practical, the vibration offset during the operation of the belt can be effectively tested, the practicability is stronger, and at the same time, the provided installation support device can arbitrarily adjust the running speed of the belt through the drive motor, which is more practical and the detection data is more complete.

[0018] In addition, by setting the belt adaptation part, different belt styles can be better adapted, and it can be applied to toothed belts and non-toothed belts, with stronger adaptability. The set adjustable floating part, combined with the set tensioning device, can realize the tensioning drive for belts of different lengths, and at the same time, floating lifting detection can be realized, which can effectively improve the practicality of the overall structure. On the one hand, the anti-detachment effect of the belt can be detected. On the other hand, when the liftable belt adaptation part on the adjustable floating part lifts, the belt can be pulled to detect its strength. At the same time, during the lifting process of the liftable belt adaptation part, the belt pulley can accelerate the friction of the non-toothed belt to accelerate the wear resistance detection effect. At the same time, the set adjustable floating part can freely adjust the lifting height, with stronger practicality, the overall structure is simpler and more stable, and the practicality is stronger. It can be better applied to different belt test requirements, and can better test the influence of the stability of the pulley on the vibration stability of belt transmission. By rotating the adjustment screw rod, the tensioning moving plate can be driven to move. During the process, the belt adaptation part can be driven to move simultaneously to realize belt tensioning. The set adjustment mounting plate can drive the overall lowering of the adjustment mounting plate by rotating the extrusion cam to squeeze and fit the adjustment plate. The adjustment screw rod can be rotated to control the lifting height of the adjustment mounting plate. The overall operation is simple and flexible, and the belt test is more comprehensive, which can be better applied to different detection requirements.

[0019] In addition, by setting the transmission docking device, transmission can be realized in a linked manner, and at the same time, manual free control of the docking drive can be achieved, which is more practical. At the same time, linkage can be assisted. The set sliding mounting cylinder adopts a method of setting four chutes, with a clever and practical structure. It can not only move and adjust its position following the tensioning moving plate, but also be driven by the transmission shaft. Similarly, the set rotating propulsion cylinder can drive the sliding docking engaging gear disk to engage with the driving gear disk. At the same time, the driving transmission shaft with a hexagonal column structure can also ensure the transmission effect during rotation. The structure is simple and practical, and the control is more flexible.

[0020] In addition, by adopting a propulsion control part, combined with the set dual-purpose extrusion part, the detection functionality can be effectively improved. The tensioning force can be dynamically adjusted, making it more flexible to use. Friction heating can be assisted to make the belt withstand high temperatures and test the influence of temperature on belt transmission. At the same time, the belt can be strongly scraped for destructive testing, and the anti-wear effect of the belt outer skin can be better tested. At the same time, under the extrusion of the extrusion propulsion block and the sliding scraping block, a load will be generated. At this time, it can be observed whether the belt pulley on the rotating mounting shaft slips. The overall test is more comprehensive and practical, and a clear understanding of the belt performance can be obtained, which is more convenient for subsequent assistance in improving the process quality of belt production. By rotating the scraping lift screw rod, the sliding scraping block can be driven to rise in height to achieve strong scraping, accelerate the destructive testing, and detect the strength of the belt after being damaged. The overall operation is simpler, easier to start, and the test is more efficient and accurate. Brief Description of the Drawings

[0046] Specific usage and function of this embodiment: In the present invention, first, the adjusting threaded rod 504 is rotated to drive the tensioning movable plate 401 to move. In the process, the belt adapter 6 can be driven to move at the same time to achieve the tensioning of the belt. The adjusting mounting plate 501 is set, and the sliding control plate 705 is moved to realize that when the driving shaft 104 rotates, the transmission shaft 701 is driven to rotate at the same time, and the extrusion cam 703 on the sliding mounting cylinder 702 is driven to rotate.

By squeezing the cam 703 and rotating the squeezing and fitting adjustment plate 505, the overall height of the adjustment mounting plate 501 can be driven to drop. At the same time, the elastic reset can be achieved by squeezing the spring on the lifting sliding shaft 5011. The structure is simple and stable, and it can be rotated. The threaded rod 504 is adjusted to drive the adjustment shaft frame 503 to rise and fall, that is, to drive the fitting adjustment plate 505 to rise and fall to adjust the height, so as to control the lifting height of the adjustment mounting plate 501. The driving motor 103 is driven to drive the belt to run. The extrusion control roller 803 can be controlled to move by rotating the propulsion control threaded rod 802. The extrusion control roller 803 can be directly used to extrude the belt, or the extrusion propulsion block 901 can be used to extrude the belt. This can be achieved by rotating the extrusion drive threaded rod 902. At the same time, the extrusion drive threaded rod 902 can be continuously rotated to drive the extrusion propulsion. Block 901 rubs against the belt, causing the belt to generate frictional heat. By rotating the scraping lifting screw rod 904, the sliding scraping block 903 can be driven to rise in height, achieving strong scraping and accelerating destructive testing. It can be observed whether the pulley 602 on the rotating mounting shaft 102 is slipping. By rotating the detection advancing threaded rod 202, the external vibration detector 302 can be driven to connect the belt periphery for detection. At the same time, by rotating the detection threaded rod 304, the upper vibration detector 303 can be driven to detect the side vibration parameters of the belt. By rotating the lateral driving threaded rod 205, the lateral position of the detection can be adjusted.

[0047] Finally, it should be noted that when describing the position of each component and the matching relationship between them, the present invention usually takes one / a pair of components as an example. However, those skilled in the art should understand that such position, matching relationship, etc. are also applicable to other components / other pairs of components.

[0048] The above description is merely an exemplary embodiment of the present invention and is not intended to limit the protection scope of the present invention. The protection scope of the present invention is determined by the appended claims.
