Description

Technical Field

[0001] This utility model belongs to the field of conveyor belt maintenance technology, and specifically relates to a conveyor belt maintenance device. Background Technology

[0002] A conveyor belt is an industrial equipment component used for the continuous carrying and transport of materials. It is usually made of flexible materials and is a device that achieves the directional transport of materials through friction. In order to prevent the conveyor belt from tearing during use, it is necessary to use appropriate maintenance devices to detect cracks on the surface of the conveyor belt.

[0003] Most existing conveyor belt crack inspection devices directly monitor the conveyor belt surface using cameras. However, some minute cracks and damages are difficult for cameras to detect accurately, and these can easily lead to tearing, resulting in poor monitoring performance and limiting the applicability of the devices.

[0004] Therefore, a conveyor belt maintenance device is needed to solve the problem that some minor cracks and damages in the existing technology are not easy for cameras to detect accurately, but in practice they are also prone to tearing, resulting in poor monitoring results. Summary of the Invention

[0005] The purpose of this invention is to provide a conveyor belt maintenance device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a conveyor belt maintenance device, comprising two bases, a conveyor belt body disposed at the middle position of the two bases, and a crack detection mechanism acting on the conveyor belt body, for detecting cracks on the surface of the conveyor belt body during operation, wherein the conveyor belt body (2) is provided with a reflective interlayer.

[0007] The crack detection mechanism includes a support plate fixed between the two bases at the bottom of the conveyor belt body, a movable plate attached to the top of the support plate, multiple cameras fixed to the top of the movable plate, two openings on the inner surface of the bases, sliding seats slidably inserted into the openings, a movable shaft positioned between the two sliding seats in the same front-back direction, a clamping roller fixedly sleeved on the outer circumference of the movable shaft, a curved belt assembly acting on the sliding seats, and a moving assembly acting on the movable plate.

[0008] It should be noted in the solution that the curved belt assembly includes a storage groove formed on the surface of the sliding seat, an embedded shaft fixed inside the storage groove, sliding sleeves slidably sleeved on the upper and lower ends of the outer circumferential surface of the embedded shaft, and a spring fixedly sleeved on the outer circumferential surface of the embedded shaft near the position of the adjacent sliding sleeve.

[0009] It is worth noting that one end of the movable shaft is rotatably connected to the surface of the adjacent sliding sleeve, one end of the spring is fixed to the surface of the adjacent sliding sleeve, and the other end of the spring is fixed to the inner wall of the storage groove.

[0010] Furthermore, the curved belt assembly also includes a first threaded rod that is threaded through and connected to one side of the two sliding seats located in the storage slot, a motor fixed at the middle position of the top of one of the bases, a rotating shaft rotatably connected to the top of the motor of one of the bases, a first bevel gear fixedly sleeved on the output end of the motor and extending out of the base from the first threaded rod, and a plurality of second bevel gears fixedly sleeved on the outer circumference of the rotating shaft.

[0011] In a preferred embodiment, the first bevel gear is meshed with the adjacent second bevel gear, and the upper and lower ends of the first threaded rod are rotatably connected to the inner wall of the base.

[0012] In a preferred embodiment, the movable component includes a rod groove formed on the surface of the support plate, a second threaded rod rotatably connected inside the rod groove, and a threaded sleeve threadedly connected to the outer circumferential surface of the second threaded rod.

[0013] In a preferred embodiment, one side of the second threaded rod passes through the support plate and extends to the outside of the support plate, and the top of the threaded sleeve is fixed to the surface of the bottom of the movable plate.

[0014] Compared with the prior art, the conveyor belt maintenance device provided by this utility model has at least the following beneficial effects:

[0015] (1) The bottom of the conveyor belt body is bent by the curved belt assembly to make it bend into an S shape, which can amplify the cracks on the surface of the conveyor belt body, so that the camera can accurately monitor the cracks on the surface of the conveyor belt body, thereby improving the monitoring effect of the conveyor belt body.

[0016] (2) The position of the movable plate and the camera in the horizontal direction can be adjusted by moving the component, so that the camera can be adjusted to one side for easy maintenance, thereby further improving the ease of use of the device. Attached Figure Description

[0023] Please see Figure 1-5 This utility model provides a conveyor belt maintenance device, including two bases 1, a conveyor belt body 2 located in the middle of the two bases 1, and a crack detection mechanism acting on the conveyor belt body 2, used to detect cracks on the surface of the conveyor belt body 2 during operation. The conveyor belt body (2) is provided with a reflective interlayer inside.

[0024] The crack detection mechanism includes a support plate 3 fixed between two bases 1 at the bottom of the conveyor belt body 2, a movable plate 5 attached to the top of the support plate 3, multiple cameras 6 fixed to the top of the movable plate 5, two openings 7 on the inner surface of the base 1, a sliding seat 8 slidably inserted into the opening 7, a movable shaft 10 located at the middle position of the two sliding seats 8 in the same front-back direction, a clamping roller 11 fixedly sleeved on the outer circumference of the movable shaft 10, a curved belt assembly acting on the sliding seat 8, and a moving assembly acting on the movable plate 5.

[0025] When it is necessary to monitor cracks on the surface of the conveyor belt body 2 during operation, the bottom of the conveyor belt body 2 is first bent into an S-shape by the curved belt assembly. This magnifies the cracks on the surface of the conveyor belt body 2, making it easier for the camera 6 to accurately monitor the cracks on the surface of the conveyor belt body 2, thereby improving the monitoring effect of the conveyor belt body 2. The position of the movable plate 5 and the camera 6 in the horizontal direction can be adjusted by the moving assembly, so that the camera 6 can be adjusted to one side for easy maintenance, thereby further improving the ease of use of the device. At the same time, the reflective interlayer (such as aluminum foil layer) set inside the conveyor belt body 2 makes it easier to detect when the conveyor belt body 2 is damaged or broken, under the action of the crack detection mechanism, because the reflective interlayer at the crack of the conveyor belt body 2 will be reflected by the external light, thus improving the maintenance efficiency.

[0026] Please see Figure 1-5 The curved belt assembly includes a storage groove 15 formed on the surface of the sliding seat 8, an embedded shaft 16 fixed inside the storage groove 15, a sliding sleeve 17 slidably sleeved on the upper and lower ends of the outer peripheral surface of the embedded shaft 16, and a spring 18 fixedly sleeved on the outer peripheral surface of the embedded shaft 16 near the adjacent sliding sleeve 17. One end of the movable shaft 10 is rotatably connected to the surface of the adjacent sliding sleeve 17, one end of the spring 18 is fixed to the surface of the adjacent sliding sleeve 17, and the other end of the spring 18 is fixed to the inner wall of the storage groove 15.

[0027] Since the two clamping rollers 11 can clamp the bottom of the inner surface of the conveyor belt body 2 and the bottommost position, the user can adjust the position of the sliding seat 8 to make one sliding seat 8 move up and the other sliding seat 8 move down, thereby bending the bottom of the conveyor belt body 2. Since the movable shaft 10 can rotate, the conveyor belt body 2 can pass through the two clamping rollers 11 without affecting its movement. Furthermore, due to the setting of the spring 18, the spring 18 will slightly contract when the two clamping rollers 11 clamp the surface of the conveyor belt body 2, thereby making the clamping rollers 11 more stable in clamping the conveyor belt body 2. Moreover, when the device shakes due to external forces, the conveyor belt body 2 will not get stuck due to the extension and contraction characteristics of the spring 18.

[0028] Please see Figure 1-5 The curved belt assembly also includes a first threaded rod 9 that is threaded through and connected to one side of the storage slot 15 of two sliding seats 8, a motor 4 fixed at the top middle position of one of the bases 1, a rotating shaft 12 rotatably connected to the top of the motor 4 of one of the bases 1, a first bevel gear 13 fixedly sleeved on the output end of the motor 4 and extending out of the base 1 from the first threaded rod 9, and a plurality of second bevel gears 14 fixedly sleeved on the outer circumferential surface of the rotating shaft 12. The first bevel gear 13 and the adjacent second bevel gear 14 are meshed and connected. The upper and lower ends of the first threaded rod 9 are rotatably connected to the inner wall of the base 1.

[0029] By starting the motor 4, the rotating shaft 12 rotates due to the meshing of one set of first bevel gears 13 and second bevel gears 14, and the two first threaded rods 9 rotate due to the meshing of the remaining first bevel gears 13 and second bevel gears 14. Due to the different positions of the second bevel gears 14 relative to the first threaded rods 9, the two first threaded rods 9 rotate in opposite directions. Since the inner wall of the opening 7 can limit the movement trajectory of the sliding seat 8, it can only slide in the vertical direction. Thus, under the action of the threaded structure between the sliding seat 8 and the adjacent first threaded rods 9, the sliding seat 8 can move in the vertical direction. Since the first threaded rods 9 rotate in opposite directions, one sliding seat 8 can move vertically downward and the other sliding seat 8 can move vertically upward, so that the two clamping rollers 11 can bend the conveyor belt body 2 into an S-shape.

[0030] Please see Figure 1-5 The movable component includes a rod groove 19 formed on the surface of the support plate 3, a second threaded rod 20 rotatably connected inside the rod groove 19, and a threaded sleeve 21 threadedly connected to the outer circumferential surface of the second threaded rod 20. One side of the second threaded rod 20 passes through the support plate 3 and extends to the outside of the support plate 3. The top of the threaded sleeve 21 is fixed to the bottom surface of the movable plate 5.

[0031] By rotating the second threaded rod 20, the inner wall of the rod groove 19 can resist and limit the threaded sleeve 21, allowing it to slide only along the inner cavity of the rod groove 19. Thus, under the cooperation between the internal thread structure of the inner wall of the threaded sleeve 21 and the external thread structure of the outer circumference of the second threaded rod 20, the movable plate 5 can be driven to move in the horizontal direction, thereby moving the movable plate 5 to a position closer to the base 1, so that the camera 6 can be closer to the outside of the device, thus facilitating the user to perform maintenance work on the camera 6.

[0032] The motor 4 can be purchased from the market. The motor 4 is equipped with a power supply. It is a mature technology in this field and has been fully disclosed. Therefore, it will not be described again in the specification.
