Description

A plurality of groups of first linkage sticks 5 are internally rotatably connected to the front linkage linear speed regulating platform 1, and a first chain 6 is provided on one end surface of the plurality of groups of first linkage sticks 5. When the first front stick motor 4 is started, one group of the first linkage sticks 5 can be driven to rotate, and the remaining first linkage sticks 5 are rotated through the first chain 6.

[0038] In one embodiment, Figure 2 As shown, a second front stick motor 12 is fixedly connected to a rear end side of the front linkage linear speed adjusting platform 1, one end of the second front stick motor 12 is fixedly connected to a first rotating rod 13, one end of the first rotating rod 13 is rotatably connected to the front linkage linear speed adjusting platform 1, and starting the second front stick motor 12 can drive the first rotating rod 13 to rotate, and a second rear stick motor 17 is fixedly connected to a rear end side of the rear linkage linear speed adjusting platform 3, one end of the second rear stick motor 17 is fixedly connected to a second rotating rod 18, and one end of the second rotating rod 18 is rotatably connected to the rear linkage linear speed adjusting platform 3, and starting the second rear stick motor 17 can drive the second rotating rod 18 to rotate.

[0039] In one embodiment, Figure 1 As shown, one side of the top of the front linkage line speed adjustment platform 1 is fixedly connected to a speed display panel 19 of the front linkage line speed measuring instrument, and the other side is fixedly connected to a first speed adjustment and speed display panel 20, which is used to set the speed of the first front stick motor 4 and the second front stick motor 12, and can display the speed measured by the speed measuring instrument 10 of the front linkage line. One side of the top of the rear linkage line speed adjustment platform 3 is fixedly connected to a speed display panel 21 of the rear linkage line speed measuring instrument, and the other side is fixedly connected to a second speed adjustment and speed display panel 22, which is used to set the speed of the first rear stick motor 14 and the second rear stick motor 17, and can display the speed measured by the speed measuring instrument 11 of the rear linkage line. One side of the top of the rear linkage line speed adjustment platform 3 is fixedly connected to an indicator light 23. When the speeds of the front and rear motors are inconsistent, timely reminders can be given through the indicator light 23.

[0040] Working principle: The above embodiment discloses a multi-stage adjustable front and rear linkage line speed adjustment device, wherein, when in use, the fixed block 901 is inserted into the fixed groove 903, and the surface of the fixed block 901 will squeeze the pin 906 and the spring 905. When the fixed block 901 is in a suitable position, the spring 905 resets and pushes the pin 906 into the interior of the slot 902, so that the speed measuring instrument 10 of the front linkage line and the speed measuring instrument 11 of the rear linkage line are connected to the fixed block 901. Twist the screw 908, the screw 908 passes through the threaded hole 907 and is threadedly connected to the fixed block 901, so that the speed measuring instrument 10 of the front linkage line and the speed measuring instrument 11 of the rear linkage line are fixed on the fixed frame 8 through the fixed block 901, thereby completing the installation of the speed measuring instrument 10 of the front linkage line and the speed measuring instrument 11 of the rear linkage line. Starting the second front stick motor 12 can drive the first rotating rod 13 to rotate, and starting the first front stick motor 4 can drive one group of the first linkage sticks 5 to rotate, and the remaining first linkage sticks 5 can rotate through the first chain 6.

[0041] The first rotating rod 13 is driven by the second front-roller motor 12, the first linkage rod 5 is driven by the first front-roller motor 4, the speed matching setting of the first front-roller motor 4 and the second front-roller motor 12 is the same, the second rotating rod 18 is driven by the second rear-roller motor 17, the second linkage rod 15 is driven by the first rear-roller motor 14, the speed matching setting of the first rear-roller motor 14 and the second rear-roller motor 17 is the same, that is, when the speed of the second rear-roller motor 17 is determined, the speed matching of the first rear-roller motor 14 is the same as that of the second rear-roller motor 17, thereby achieving a stable state of linkage line speed, and the upper half of the front linkage line speed adjustment platform 1 is measured by the speed measuring instrument 10 of the front linkage line and displayed on the speed display panel 19 of the front linkage line speed measuring instrument. The upper half of the rear linkage line speed adjustment platform 3 is measured by the speed measuring instrument 11 of the rear linkage line and displayed on the speed display panel 21 of the rear linkage line speed measuring instrument. Example of setting the preset range of the percentage difference of the front and rear linkage line speeds: the percentage difference of the front and rear linkage line speeds is 5%, the speed of the second rear roller motor 17 is set by the second speed adjustment and speed display panel 22, and it drives the second rotating rod 18 to move, when the speed measuring instrument 11 of the rear section linkage line measures the actual speed of the half-component to reach 95% of the actual speed of the half-component measured by the speed measuring instrument of the front section linkage line, the set speed of the second rear roller motor 17 at this time is recorded (due to kinetic energy loss, the second rear roller motor 17 ≠ the actual speed of the half-component measured by the speed measuring instrument 11 of the rear section linkage line) , that is, the half-component is at the lowest point of the operating range of the second angle radian sensor 25, the speed measuring instrument 11 of the rear-section linkage line measures the actual speed of the half-component to reach 105%, the speed measuring instrument 10 of the front-section linkage line measures the actual speed of the half-component, and records the set speed of the second rear roller motor 17 at this time (due to kinetic energy loss, the second rear roller motor 17 ≠ the actual speed of the half-component of the speed measuring instrument 11 of the rear-section linkage line), that is, the second angle radian sensor 25 records the highest point of the operating angle or radian of the disc, thereby determining the preset control range of the second angle radian sensor 25.

[0042] When the front and rear speed difference percentage exceeds the preset range requirement (at this time, the running angle or curvature of the disc recorded by the second angle radian sensor 25 is also out of tolerance), the second angle radian sensor 25 gives feedback, and the second rear roller motor 17 adjusts the speed so that the running angle or curvature of the disc recorded by the second angle radian sensor 25 reaches the previous running preset range (the preset range of the front and rear speed difference percentage can be set, such as the above 5%). The indicator light 23 gives a red alarm and performs speed adjustment. When the front and rear speed difference percentage is within the preset requirement range, but does not meet the more stringent standard range requirements, the speed measuring instrument measures the speed and feeds it back to each motor, and the speed is adjusted between the motors to meet the more stringent standard requirement range (the more stringent standard requirement range can be set, such as 1%). The indicator light 23 gives a yellow alarm and performs speed adjustment. When the front and rear speed difference percentage reaches the more stringent standard range requirements, the indicator light 23 is green and qualified, and no speed adjustment is performed. When the front and rear speed difference percentage reaches the more stringent standard range requirements, the indicator light 23 is green and qualified, and no speed adjustment is performed.

[0043] The speed measuring instrument continuously measures the front and rear speed difference in real time and records it, and calculates the front and rear speed difference percentage. If the second angle radian sensor 25 records the running angle or radian of the disk beyond the previous running preset range, the feedback mode is the feedback of the second angle radian sensor 25, because the floating stick 706 has sensitive feedback and responds quickly, but the accuracy is low. When it exceeds the preset range, it needs to respond quickly. But when the front and rear speed difference percentage is within the preset requirement range, but does not meet the more stringent standard range requirements, the feedback mode is the speed measuring instrument, the speed measuring instrument measures the speed and feeds it back to the motor, and the motor adjusts the speed to meet the more stringent standard requirement range. The feedback adjustment requires calculation, so the reaction speed is slow, but the accuracy is high. Through the first angle radian sensor 24, the running angle or radian of the disk is checked at intervals (the inspection interval time can be set) to eliminate external forces such as equipment.

[0044] When it is necessary to keep the floating rod 706 balanced in weight, the turntable 710 is rotated, and the turntable 710 drives the threaded rod 709 to rotate, so that the gravity block 712 can slide. At the same time, when the gravity block 712 slides in the slide groove 708, the slide groove 708 will play a limiting role, so that the gravity block 712 will not rotate and there will be no shaking when sliding. The balance between the floating rod 706 and the gravity block 712 is adjusted by the left and right movement of the gravity block 712, so that the floating rod 706 maintains a balanced weight. The floating rod 706 rotates, driving the front disc to rotate. The second angle arc sensor 25 records the running angle or arc of the disc, so that it can achieve the weight offset balance of the floating rod 706. When the half component passes through the floating rod 706, the influence of gravity on the floating rod 706 is reduced, so that it passes through the floating rod 706 in a natural state.

[0045] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
