[0023] Example 1

[0024] like Figure 1-Figure 3 As shown, the present invention proposes a treadmill belt tension testing device comprising a frame 1, a running belt 5, a mounting plate 8, a lifting drive assembly, a translation drive assembly, and a control assembly. The frame 1 is rotatably connected to the active roller 2 and the passive roller 3. The frame 1 is connected to the running deck 4, and a bracket 7 is provided on the frame 1. The running deck 4 is positioned between the active roller 2 and the passive roller 3. The upper surface of the running deck 4 is smooth, and the running deck 4 and the active roller 2 do not contact each other, thereby providing a suspended area between them. A roller 15 is positioned above the suspended area. The running belt 5 is drivingly connected to the active roller 2 and the passive roller 3. The lower surface of the upper horizontal end of the running belt 5 is slidably connected to the upper surface of the running deck 4, and the lower surface of the running deck 4 does not contact the running belt 5. The mounting plate 8 is connected to the bracket 7 and slidably connected to the movable plate 9. The movable plate 9 is slidably connected to the pressure sensor 13. The detection end of the pressure sensor 13 is connected to the suspension rod 14, and the lower end of the suspension rod 14 is rotatably connected to the roller 15. The lifting drive assembly includes but is not limited to a hydraulic cylinder 10, the cylinder barrel of the hydraulic cylinder 10 is connected to the mounting plate 8, the push rod of the hydraulic cylinder 10 is connected to the movable plate 9, and a plurality of sliding rods slidably connected to the mounting plate 8 are provided, and the sliding rods are connected to the movable plate 9. The lifting drive assembly drives the movable plate 9 to rise and fall. The translation drive assembly includes but is not limited to a slide 11 and a linear module 12, the slide 11 is slidably connected to the movable plate 9, and the slide 11 is connected to the body of the pressure sensor 13. The linear module 12 is connected to the movable plate 9, and the linear module 12 drives the slide 11, and the translation drive assembly drives the roller 15 to move in a direction perpendicular to the transmission direction of the running belt 5. The control assembly includes a controller and a display, the display is electrically connected to the controller, and the controller is electrically connected to the hydraulic cylinder 10, the pressure sensor 13 and the translation drive assembly.

[0025] In this embodiment, during detection, the hydraulic cylinder 10 first presses down the movable plate 9 and the roller 15 to lower their height. When the pressure sensor 13 detects a pressure signal, the hydraulic cylinder 10 stops working, and the controller records the propulsion distance of the hydraulic cylinder 10 as 0 in this state. Then the hydraulic cylinder 10 presses down the movable plate 9 and the roller 15 to continue to descend to a certain height. At this height, the treadmill 5 is deformed concavely by the pressure of the roller 15. The pressure sensor 13 detects the pressure data at the current position, and then the linear module 12 drives the slide 11 to slide, thereby driving the roller 15 to roll on the treadmill 5. During the rolling process, the pressure sensor 13 continuously records the changes in the pressure signal. Through this detection method, the precise tension value of the treadmill 5 can be effectively detected, and at the same time, it can also be detected whether the treadmill 5 is deviating.

[0028] In this embodiment, by providing a support roller 6, the roller 15 is prevented from contacting the edge of the running deck 4 when pressing down the treadbelt 5 to cause the upper end of the treadbelt 5 to be concave, thereby preventing the friction between the treadbelt 4 and the treadbelt 5 from increasing instantaneously and causing the deformation of the treadbelt 5 to be affected, thereby improving the accuracy of the tension test of the treadbelt 5 and protecting the treadbelt 5 at the same time.
