Description

Technical Field

[0001] This invention belongs to the field of belt conveyor idler detection technology, specifically relating to an integrated detection device for idler damping and roller surface runout. Background Technology

[0002] Belt conveyors, also known as belt conveyors or rubber belt conveyors, are key equipment frequently used in bulk material conveying operations. A belt conveyor mainly consists of a head roller, a tail roller, a conveyor belt, an intermediate frame, and several upper and lower idler roller assemblies. An idler roller assembly mainly comprises an idler frame and idlers rotatably mounted on the frame. Upper idler roller assemblies are typically trough-type three-section idlers, while lower idler roller assemblies are typically V-type two-section idlers. Idler rollers generally consist of roller skin, roller shaft, bearing housing, bearings, and seals. The roller shaft passes coaxially through the inside of the cylindrical roller skin. The bearing housing is welded to the inner sides of both ends of the roller skin. The bearing is installed inside the bearing housing and rolls between the roller shaft and the roller skin. The seal primarily seals the outer end of the bearing housing, providing sealing protection for the bearing. However, during the production of idler rollers, there are certain deviations in the coaxiality between the roller shaft, roller skin, and bearing housing. In addition, there is a certain rolling friction between the inner and outer rings of the bearing and the steel balls. Moreover, the bearings are installed using a press-fit assembly method. After the idler rollers are assembled, there may be problems such as insufficient bearing rotation leading to excessive roller shaft rotation damping, or imperfect coaxiality between the roller skin and the roller shaft causing roller surface runout during rotation. Therefore, assembled idler roller products need to undergo rolling damping and roller surface runout tests. Only idler roller products that meet the damping and runout test standards are considered qualified products to ensure the quality of the finished idler rollers and provide safety assurance for the subsequent operation and use of the belt conveyor.

[0003] However, currently, the damping and runout testing of finished idler rollers mainly relies on manual inspection by quality control personnel. This method is inefficient, labor-intensive, and prone to human error, leading to missed or incorrect inspections and posing potential quality control risks. To address these issues with manual inspection, some idler roller manufacturers have developed damping testing equipment, while others have designed corresponding roller runout (radial runout) testing equipment. However, these devices still have structural and functional limitations. They are simple in structure and limited in function. After the idler roller is tested on the damping testing equipment, it must be removed and reinstalled on the runout testing equipment for further testing. This operation is cumbersome, resulting in low efficiency and increasing the workload of quality control personnel. Therefore, there is an urgent need to find a more reasonable integrated testing device for idler roller damping and roller runout. Summary of the Invention

[0004] In response to the above situation, the present invention provides an integrated detection device for idler damping and roller surface runout, which is used to perform quality control detection on the assembled idler shaft rotation flexibility, coaxiality, and whether there is severe runout of the roller surface when the idler rotates during the production process of belt conveyor idlers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An integrated detection device for idler roller damping and roller surface runout includes a fixed base, and an idler roller rolling support mechanism, a damping detection mechanism, and a radial runout detection mechanism installed on the fixed base.

A sliding motor is connected to one end of the positive and negative threaded rod to drive the left and right movable base plates to move towards each other or away from each other.

[0009] Furthermore, the left and right lifting brackets are two vertically adjustable support plates. The upper ends of the two vertical support plates are respectively provided with two rotatable support rollers, which are used to cooperate in rolling support on the lower left and right ends of the idler roller workpiece. Each of the two vertical support plates is connected to a lifting connecting plate in the middle of its opposite side. The lower part of the two lifting connecting plates is provided with an electric lifting assembly and a lifting guide assembly for driving the vertical support plates to move up and down.

[0010] Furthermore, the electric lifting assembly includes worm gear reducers fixed on the left and right movable base plates respectively, and lifting motors that are correspondingly connected to the input ends of the two worm gear reducers. The output ends of the two worm gear reducers are correspondingly connected to the two lifting connecting plates.

[0011] Furthermore, the friction drive wheel and the rolling motor are elliptical and can be mounted above the right inspection frame via a drive lifting bracket. The drive lifting bracket includes a support connecting frame fixedly connected to the right inspection frame, and a power mounting frame elliptical and can be connected to the left side of the support connecting frame. The right side of the power mounting frame is provided with a lifting cylinder and a lifting guide assembly for driving its lifting movement.

[0012] Furthermore, a left mounting platform is provided in the middle of the left inspection frame. Two linear guide rails extending in the left-right direction are fixedly laid on the left mounting platform. The bottom of the inspection slide is slidably connected to the two linear guide rails via linear sliders. A push-pull cylinder for driving the inspection slide to slide left and right is installed on one side of the left mounting platform. The piston rod of the push-pull cylinder is connected to the inspection slide via a connecting frame.

[0013] Furthermore, a right mounting platform is provided in the middle of the right inspection frame, and a three-axis cylinder with a self-guiding function is installed below the left and right mounting platforms respectively. Each of the two three-axis cylinders has a set of limiting wheel assemblies installed at one end facing each other. The limiting wheel assembly includes a rotatable vertical side guard wheel for limiting the left / right ends of the roller workpiece, and an L-shaped connecting frame for connecting the vertical side guard wheel to the top end of the telescopic rod of the three-axis cylinder.

[0014] Furthermore, a workpiece detection sensor is also fixedly installed on the right mounting platform via a connecting bracket, which is used to detect whether there are idler roller workpieces placed above the left and right lifting brackets.

[0015] Furthermore, the left and right ends of the damping detection shaft are rotatably connected to the detection slide via bearings with mounting seats. The clamping assembly includes a finger cylinder and clamping fingers correspondingly installed on each working end of the finger cylinder. The detection shaft of the torque sensor is coaxially connected to the damping detection shaft via a coupling, and the housing of the torque sensor is fixedly connected to the detection slide via a connecting seat.

[0016] Furthermore, both of the aforementioned ranging sensors are laser ranging sensors. Each of the two ranging sensors is connected to the top of the cylinder rod of the two telescopic cylinders via a movable mounting bracket.

Detailed Implementation

[0020] The present invention will now be clearly described in conjunction with the accompanying drawings and specific embodiments. Any modifications, equivalent substitutions, improvements, etc., made by those skilled in the art based on the embodiments of the present invention without inventive effort to obtain all other embodiments should be included within the scope of protection of the present invention.

[0021] In the description of this invention, it should be noted that the terms "upper," "lower," "left," "right," "inner," "outer," "center," "vertical," and "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for ease of description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] Example 1 like Figure 1-4 As shown, an integrated detection device for idler roller damping and roller surface runout includes a fixed base 1, and an idler roller rolling support mechanism, a damping detection mechanism, and a radial runout detection mechanism installed on the fixed base. The fixed base is prior art, and its specific structure will not be described in detail here.

[0023] The roller rolling support mechanism includes a left movable base plate 2 and a right movable base plate 3 that can be slidably disposed on the fixed base in opposite directions, and a left lifting bracket 4 and a right lifting bracket 5 symmetrically disposed on opposite sides of the left and right movable base plates for cooperating to roll and support the roller workpiece. It also includes a friction drive wheel 6 that can be lifted and disposed above the roller workpiece for driving the roller workpiece to rotate and roll. The friction drive wheel is connected to a rolling motor 7. The rolling power of the roller workpiece to be tested comes entirely from the rolling friction force of the friction drive wheel. In order to further improve the friction coefficient between the friction drive wheel and the surface of the roller workpiece, the rolling friction contact surface of the friction drive wheel is also covered with a rubber layer.

[0024] The fixed base has two linear guide rails 8 extending in the left-right direction laid on the front and rear sides of its upper surface. The left and right movable base plates are slidably connected to the two linear guide rails 8 via linear sliders 9. A forward and reverse threaded rod 10 extending in the left-right direction is rotatably mounted in the middle of the fixed base. The bottoms of the left and right movable base plates are respectively screwed to the left and right ends of the forward and reverse threaded rod via threaded sleeves. One end of the forward and reverse threaded rod is connected to a sliding motor 11, which drives the left and right movable base plates to move towards each other or away from each other. The sliding motor is a variable frequency motor with forward / reverse switching and speed adjustment functions. By driving the forward and reverse threaded rod to rotate forward or backward, the left and right movable base plates can move towards each other or away from each other, improving the adaptability of the detection device to roller workpieces of different lengths. To facilitate the left-right sliding movement of the two sliding motors, the power and control lines of the sliding motors are all threaded through the matching cable tray groove. The aforementioned positive and negative threaded screws and threaded sleeves are all existing technologies, and their specific configurations will not be described in detail here.

[0025] like Figure 5 , 6 As shown, the left and right lifting supports are two vertically adjustable support plates. Two rotatable support rollers 12 are symmetrically arranged at the upper ends of each vertical support plate, used to provide rolling support on the lower left and right sides of the idler roller workpiece. A U-shaped clearance groove is provided at the top of the vertical support plate between the two support rollers, and multiple sets of roller mounting holes 13 are symmetrically arranged below the U-shaped clearance groove. Depending on the selection of the support rollers, different roller mounting holes can be installed, allowing adjustment of the support spacing between the support rollers to improve the adaptability of the detection device to idler roller workpieces of different diameters. A lifting connecting plate 14 is connected to the middle of each of the two vertical support plates on opposite sides. An electric lifting assembly and a lifting guide assembly for driving the lifting movement of the vertical support plates are correspondingly arranged below the two lifting connecting plates.

[0026] The electric lifting assembly includes worm gear reducers 15 fixed to the left and right movable base plates respectively, and lifting motors 16 correspondingly connected to the input ends of the two worm gear reducers. The output ends of the two worm gear reducers are correspondingly connected to the two lifting connecting plates. The lifting motors are servo motors with encoders, which facilitates precise control of the lifting height of the worm gear reducers, thereby accurately controlling the lifting height of the two vertical support plates on the roller workpiece.

[0027] The lifting guide assembly includes linear guide rails 17 fixedly connected to the opposite sides of the two vertical support plates, and linear sliders 18 slidably connected to the linear guide rails 17. Each linear slider 18 is fixedly connected to the left and right movable base plates via a fixed bracket 19. The worm gear reducer and servo motor with encoder used here are existing technologies, and their specific configurations will not be described in detail here.

[0028] like Figure 4-8 As shown, the friction drive wheel and rolling motor are vertically and flexibly mounted above the right inspection frame via a drive lifting bracket. The drive lifting bracket includes a support connecting frame 20 fixedly connected to the upper part of the right inspection frame, and a power mounting frame 21 vertically and flexibly connected to the left side of the support connecting frame. A lifting cylinder 22 and a lifting guide assembly are provided on the right side of the power mounting frame to drive its lifting movement. The lifting guide assembly includes a linear guide rail 23 fixedly connected to the right side of the power mounting frame, and linear sliders 24 corresponding to and slidably connected to the linear guide rail 23. Each linear slider 24 is fixedly connected to the support connecting frame. Under the guidance of the lifting guide assembly, the lifting cylinder can ensure that the power mounting frame is vertically lifted and lowered. The rolling motor is also a servo motor with an encoder. To facilitate the lifting and lowering movement of the rolling motor, its power cord and control wires are all run through a matching cable chain box.

[0029] Example 2 Based on Embodiment 1, the damping detection mechanism includes a left detection frame 25 disposed above the left movable base plate, and a detection slide 26 slidably mounted on the left detection frame. It also includes a damping detection shaft 27 rotatably mounted on the detection slide. One end of the damping detection shaft near the idler roller workpiece is provided with a clamping assembly for cooperating with and holding the end of the roller shaft of the idler roller workpiece. The other end of the damping detection shaft is provided with a torque sensor 28 for detecting the rotational damping of the damping detection shaft. The torque sensor is prior art and will not be described in detail here.

[0030] The left and right ends of the damping detection shaft are rotatably connected to the detection slide via bearings 29. The clamping assembly includes a finger cylinder 30 and clamping fingers 31 correspondingly installed on each actuating end of the finger cylinder. The finger cylinder is a three-jaw finger cylinder, and the clamping fingers are correspondingly clamped by a three-jaw chuck. The clamping distance between the three jaws of the three-jaw chuck is adjustable to further improve its adaptability to rollers of different thicknesses. The finger cylinder and the three-jaw chuck are existing technologies and will not be described in detail here. The detection shaft of the torque sensor is coaxially connected to the damping detection shaft via a coupling 32, and the housing of the torque sensor is fixedly connected to the detection slide via a connecting seat 33. The torque sensor is connected to the automatic control system of the detection device. The damping of the roller can be detected and judged by measuring the rotational resistance of the roller shaft of the roller workpiece in Newtons detected by the torque sensor.

[0031] For example, the indicators for judging the damping of some models of idler rollers are shown in the table below: Table 1: Roller Damping Test Standards

[0032] The standards for judging roller damping are not entirely the same for different roller diameters and roller types. For example: for dustproof rollers with a roller diameter ≤ 108mm, the rolling resistance must not exceed 2.5N; for waterproof rollers with a roller diameter ≤ 108mm, the rolling resistance must not exceed 3.6N; for dustproof rollers with a roller diameter > 108mm, the rolling resistance must not exceed 3.0N; and for waterproof rollers with a roller diameter > 108mm, the rolling resistance must not exceed 4.35N. Otherwise, it can be judged as a defective product. As shown in Table 1.

[0033] Example 3 Based on Embodiment 2, the radial runout detection mechanism includes a right detection frame 34 disposed above the right moving base plate, and a pair of distance measuring sensors 35 symmetrically installed on the outside of the left and right detection frames for cooperating in detecting the radial runout of the roller surface of the idler roller workpiece. The two distance measuring sensors can extend and retract to approach or move away from the idler roller workpiece through a push-pull assembly.

[0034] Both of the aforementioned distance sensors employ laser distance sensors. By using the detection light from the distance sensor to measure the runout distance of the roller surface at both ends of the rolling idler workpiece, the sensor can detect and perceive factors that may cause poor roller surface runout, such as elliptical deformation and bulges.

[0035] For example, the indicators for judging the diameter runout of some idler roller models are shown in the table below: Table 2: Idler Roller Diameter Runout Detection Standard

[0036] The criteria for judging the radial runout of idlers vary depending on the belt speed and roller length used on belt conveyors. For example: for idlers with a belt speed < 3.15 m / s and a roller length < 550 mm, the radial runout should not exceed 0.6 mm; for idlers with a belt speed ≥ 3.15 m / s and a roller length < 550 mm, the radial runout should not exceed 0.5 mm; for idlers with a belt speed < 3.15 m / s and a roller length of 550–950 mm, the radial runout should not exceed 0.9 mm; and for idlers with a belt speed ≥ 3.15 m / s and a roller length of 550–950 mm, the radial runout should not exceed 0.7 mm. Otherwise, the idler is considered defective. This pattern continues, as shown in Table 2.

[0037] Two ranging sensors are each connected to the top of the cylinder rod of two telescopic cylinders via a movable mounting bracket 36. Linear guide rails 37 are provided on the outer side of each of the two telescopic cylinders. The movable mounting brackets are slidably connected to the two linear guide rails 3 via linear sliders 38. The two linear guide rails 3 and the two telescopic cylinders are respectively fixedly installed on the outer side walls of the left and right detection frames.

[0038] A left mounting platform 39 is provided in the middle of the left inspection frame. Two linear guide rails 40 extending in the left and right directions are fixedly laid on the left mounting platform. The bottom of the inspection slide is slidably connected to the two linear guide rails 40 through a linear slider 41. A push-pull cylinder 42 for driving the inspection slide to slide left and right is fixedly installed on one side of the left mounting platform. The piston rod of the push-pull cylinder is connected to the inspection slide through a connecting bracket 43.

[0039] A right mounting platform 44 is located in the middle of the right inspection frame. A three-axis cylinder 45 with a self-guiding function is installed below each of the left and right mounting platforms. Each of the two three-axis cylinders has a set of limiting wheel assemblies installed at its facing end. The limiting wheel assembly includes a rotatable vertical sidewall wheel 46 for limiting the left / right ends of the roller workpiece, and an L-shaped connecting frame 47 for connecting the vertical sidewall wheel to the top of the telescopic rod of the three-axis cylinder. The three-axis cylinder with a self-guiding function is prior art and will not be described in detail here.

[0040] Example 4 Based on Example 3, such as Figure 1 , 5As shown, a workpiece detection sensor 49 is also fixedly installed on the right mounting platform via a connecting bracket 48. This sensor is used to detect whether there are any roller workpieces above the left and right lifting brackets, and to send the presence or absence detection signal to the automatic control system of the detection device so as to determine whether detection work needs to be performed.

[0041] An electrical control cabinet 50 is fitted to the outside of the fixed base. The electrical control cabinet houses an automatic control system for automatically detecting, recording, and controlling the entire detection device. The rolling motor, torque sensor, distance sensor, and workpiece detection sensor are all electrically connected to the automatic control system. The electrical control cabinet contains frequency converters, servo drives, PLCs, and other control devices. The entire automated control of the detection device is completed according to a preset program. The electrical control cabinet and its automatic control system are existing technologies and will not be described in detail here.

[0042] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
