DETAILED DESCRIPTION

[0025] The technical scheme of the utility model will be described clearly and completely in combination with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0026] Referring to Figures 1 to 7 , the utility model provides a kind of technical scheme: a belt deviation and skidding detection device with positioning mechanism, including support wheel 1, support wheel 1 is the special wheel of transmission belt, support wheel 1 both ends are rotatably arranged in bearing seat 5, bearing seat 5 is slidably arranged in support frame 2 respectively, as shown in Figure 7 In actual application process, support frame 2 is installed in the end of belt conveyor both sides fixed.

[0027] Bearing seat 5 is installed as follows, as shown in Figure 1 And Figure 2As shown, the upper and lower ends of the bearing seat 5 are respectively provided with sliding seats 6, and each sliding seat 6 has a sliding groove on its end face. The upper and lower surfaces of the support frame 2 are provided with strip rails 7 that match the sliding grooves. The strip rails 7 are movably placed in the sliding grooves, so that the sliding seat 6 is not only limited by the strip rails 7, but also can only move in a straight line along the strip rails 7.

[0028] like Figure 5 As shown, the support wheel 1 is used to support the belt. When the belt needs to be tensioned or adjusted, the left and right ends of the support wheel 1 need to be adjusted. Therefore, a screw adjustment mechanism connected to the bearing seat 5 is provided at one end of each support frame 2. Figure 1 and Figure 3 As shown, the screw adjustment mechanism includes an adjusting screw 8 disposed on one side of the bearing seat 5. The adjusting screw 8 is perpendicular to the axis of the support wheel 1, and one end of the adjusting screw 8 is movably disposed inside one end of the support frame 2. The adjusting screw 8 is provided with a locking component for positioning it. The locking component is a nut disposed inside and outside the support frame 2. By rotating the nut, the extension and retraction of the adjusting screw 8 within the support frame 2 can be adjusted, thereby changing the position of both ends of the support wheel 1, thus tensioning and adjusting the belt.

[0029] like Figure 2 and Figure 4 As shown, two speed sensors 18 are provided on the side of the support wheel 1 away from the screw adjustment mechanism. Specifically, the speed sensors 18 are laser speed sensors or ultrasonic speed sensors. During installation, one speed sensor 18 is positioned with its detection direction facing the surface of the support wheel 1 to detect the rotational speed of the support wheel 1 surface, while the other speed sensor 18 is positioned with its detection direction facing downwards to detect the rotational speed of the belt. By simultaneously detecting with both speed sensors 18, the movement speeds of the support wheel 1 and the belt can be measured at the same time.

[0030] Next, the two speed sensors 18 are connected to the bearing housing 5 via brackets. These brackets include first support rods 3 connected to the speed sensors 18. It should be noted that a sensor bracket 17 is provided at the end of the first support rod 3 closest to the speed sensor 18, and the speed sensors 18 are mounted on the sensor bracket 17. The end of the first support rod 3 furthest from the speed sensor 18 is movably placed within a connecting arm 4, one end of which is connected to the side of the bearing housing 5.

[0031] The first support rod 3 can extend, retract, and rotate within the connecting arm 4, thereby changing the position of the speed sensor 18 and adjusting the irradiation direction of the speed sensor 18. The connecting arm 4 is provided with a fastener that can position the first support rod 3. The fastener is a bolt threaded on the end of the connecting arm 4. The first support rod 3 can be fixed by tightening the bolt to prevent unnecessary deflection and slippage of the first support rod 3.

[0032] The pressure sensor 14 is connected with an alarm device, such as Figure 7 As shown, the alarm device comprises a control cabinet 20, and the surface of the control cabinet 20 is provided with an alarm 21, which is an alarm horn or a sound and light alarm. The control cabinet 20 is provided with a controller, which is a host, a PLC controller or a control mainboard. Specifically, the controller is connected with the speed sensor 18 and the alarm 21 respectively;

[0033] The speed of the supporting wheel 1 and the running speed of the belt should be equal under the condition of belt tension. When the speed of the supporting wheel 1 and the running speed of the belt are compared in the controller, if the ratio does not exceed the preset value, the alarm 21 remains static. If the ratio exceeds the preset value (including higher and lower), the controller controls the alarm 21 to alarm and prompt. At this time, it can be concluded that the running speed of the belt and the speed of the supporting wheel 1 do not match, that is, the phenomenon of slipping occurs between the supporting wheel 1 and the belt.

[0034] Further, the detection device provided by the application can not only detect the phenomenon of belt slipping, but also detect whether the belt is deviated. A connecting rod 9 is arranged between the two screw adjusting mechanisms. The specific connection mode is shown in Figure 3 and Figure 4 As shown, the two ends of the connecting rod 9 are respectively provided with mounting sleeves 13, and the mounting sleeves 13 are movably sleeved on the adjusting screws 8. The adjusting screws 8 are provided with locking members for positioning the mounting sleeves 13. The locking members are nuts arranged on the adjusting screws 8 in a threaded manner. The nuts are distributed on the two sides of the mounting sleeves 13. When the nuts are loosened, the positions of the mounting sleeves 13 can be adjusted, so that the distance between the connecting rod 9 and the supporting wheel 1 is changed.

[0035] Two second supporting rods 12 are symmetrically arranged on the connecting rod 9. The ends of the second supporting rods 12 close to the supporting wheel 1 are respectively provided with pressure sensors 14. The pressure sensors 14 are connected with the alarm device. Specifically, the pressure sensors 14 are connected with the controller.

[0036] The second supporting rods 12 are movable, that is, the second supporting rods 12 are movably arranged in the support 10. The support 10 is provided with fastening members for positioning the second supporting rods 12. The fastening members are bolts arranged in the support 10 in a threaded manner. The second supporting rods 12 can be fixed by screwing the bolts. The support 10 can move back and forth along the connecting rod 9. Specifically, the support 10 is arranged at the top of the U-shaped clamping seat 11, and the U-shaped clamping seat 11 is slidably clamped on the connecting rod 9. The U-shaped clamping seat 11 is provided with fastening members for positioning it. The fastening members are bolts arranged on the side surface of the U-shaped clamping seat 11 in a threaded manner. When the U-shaped clamping seat 11 is adjusted to a preset position, the bolts can be screwed to fix the U-shaped clamping seat 11.

[0037] Specifically, as shown in Figure 5As shown, the second support rod 12 should be located on both sides of the belt, and the pressure sensor 14 should be close to the position of the two sides of the belt, so that when the belt deviates, the belt deviates to any side and contacts the pressure sensor 14. In order to better allow the pressure sensor 14 to perceive the contact force between the belt, the installation mode of the pressure sensor 14 is designed, and the specific case is as follows Figure 6 As shown, the second support rod 12 is provided with a mounting seat 19 at one end close to the support wheel 1, and the pressure sensor 14 is detachably arranged on the mounting seat 19, that is, the edge of the pressure sensor 14 is fastened with the mounting seat 19 by bolts; and a mounting disc 16 is detachably arranged on the side of the pressure sensor 14 close to the support wheel 1, the edge of the mounting disc 16 is also connected with the mounting disc 16 by bolts, and a push plate 15 extending towards the support wheel 1 is arranged in the middle of the mounting disc 16. The push plate 15 is elastic, and since the belt deviates with a large force, the push plate 15 is elastic, which can avoid the rigid contact between the push plate 15 and the belt and damage the push plate 15. The push plate 15 is a metal elastic piece.

[0038] In actual use, the push plate 15 should be adjusted to the surface of the support wheel 1 through the second support rod 12 in the support 10, so that the support wheel 1 and the end of the push plate 15 are gap matched, so that when the belt deviates, it can immediately contact the push plate 15. The push plate 15 transmits the force to the pressure sensor 14, and the pressure sensor 14 transmits the information to the controller, and the controller controls the alarm to alarm.

[0039] Based on the above embodiment, it should be noted that the control cabinet 20 can be arranged on the side of the belt conveyor, and a display screen and operation buttons are arranged on the surface of the control cabinet 20. The display screen and operation buttons are respectively connected with the controller.

[0040] Based on the above embodiment, it should be noted that the two speed sensors 18 are arranged in the belt end, which can avoid the interference of the external environment to the speed sensor 18, and the inner wall of the belt and the support wheel are smooth and clean, so that the detection data is more accurate.

[0041] Based on the above embodiment, it can be further optimized that the connecting arm 4 and the bearing seat 5 are detachably connected by bolts.

[0042] The above only describes the preferred embodiment of the present application, and does not limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
