Description

Technical Field

[0001] This invention relates to the field of axial displacement detection technology, and in particular to a lateral displacement detection device for detecting the axial displacement of idler rollers. Background Technology

[0002] As a core load-bearing and guiding component of belt conveyors, the axial displacement of idlers directly determines their assembly accuracy, bearing life, and the conveyor's operational stability. Excessive axial displacement of idlers can lead to conveyor belt misalignment, accelerated wear at the idler ends, bearing seizure, and even breakage. This not only affects the normal operation of the conveyor but may also cause equipment damage, material leakage, and other safety accidents. Therefore, idlers must undergo rigorous axial displacement testing before leaving the factory, after installation, and during routine maintenance to ensure their performance meets relevant standards.

[0003] Currently, most existing idler roller axial displacement detection devices adopt a vertical detection structure, which has certain technical drawbacks: the displacement detection stroke of existing vertical detection devices depends entirely on the vertical height of the device itself. Due to the rigid constraints of the vertical arrangement space of the frame and loading mechanism, they cannot meet the detection requirements of large-size idlers and idlers under heavy-duty conditions, and are difficult to adapt to the detection needs of different idler models. Vertical detection devices require the idlers to be vertically hoisted or fixed, and the loading and detection mechanisms are all arranged vertically, resulting in a generally high overall height of the device. This not only occupies a large amount of factory floor space and vertical space, but also makes it difficult to adapt to confined on-site maintenance scenarios, such as the maintenance of idler rollers on underground conveyors or the inspection of small factory buildings. The workstations and temporary outdoor testing points are prone to tilting and slipping due to the combined effects of their own weight and the applied load. This risk increases significantly, especially during heavy load loading, which not only threatens the safety of operators but may also damage the rollers and testing equipment, increasing testing costs. Current equipment requires manual and repeated calibration of roller positioning, and the adjustment of the applied load and displacement readings are independent, requiring separate operation of the loading mechanism, reading of displacement data, and manual recording. Displacement detection often relies on manual readings using traditional dial indicators, resulting in significant errors. Furthermore, the test data cannot be stored, exported, or analyzed in real time and must be manually compiled, leading to low testing efficiency and poor operational convenience. Summary of the Invention

[0004] The purpose of this invention is to overcome the four technical problems mentioned above in existing idler roller axial displacement detection devices, and to provide a lateral displacement detection device for detecting the axial displacement of idler rollers. This solves the problems of: vertical detection being limited by the detection stroke and having a small detection range; the overall height of the device being large, occupying a lot of space and restricting its layout; safety hazards such as idler roller slippage during operation, resulting in low safety; and the adjustment and reading process being cumbersome, with insufficient detection efficiency and ease of operation.

[0005] The present invention adopts the following technical solution: A lateral displacement detection device for detecting the axial displacement of a roller includes a frame, a loading mechanism, a detection fixing plate, and a control display placement table; the frame is integrally welded and formed from a high-strength alloy material, laid out horizontally, with an overall length range of 3000 - 4000 mm and a width range of 800 - 1000 mm. Two groups of movable and adjustable long roller fixing brackets are installed on the frame. A roller placement mechanism is provided between the two long roller fixing brackets on the left and right. A connecting frame is fixedly connected to the top of the long roller fixing bracket. The adjustment range between the front and rear of the two groups of long roller fixing brackets is 500 to 3500 mm, which can be adapted to rollers with a length of 500 to 3500 mm for axial displacement detection; a rectangular plate is fixedly welded between the connecting frames, and an installation frame is fixedly installed between the rectangular plates; a nut is clamped inside the installation frame, and a ball screw is connected to the nut through balls and an inverter. The ball screw, nut, and installation frame form a ball screw adjustment mechanism; the roller to be detected is placed on the roller placement mechanism; the loading mechanism is composed of installation steel, a jack, and a loading adjustment module, and the loading mechanism is electrically connected to the PLC controller inside the control display placement table; a displacement sensor is installed on the detection fixing plate, and the displacement sensor is electrically connected to the PLC controller.

[0006] More preferably, connecting angle plates are welded between the left and right of the installation steel. The first installation plate and the second installation plate are welded on the outside of the connecting angle plates. A vertical through slot is opened inside the first installation plate, and sliding slots are opened on both sides of the through slot. Two mutually parallel vertical sliding slots are opened inside the second installation plate. The jack is arranged parallel to the axial direction of the roller. The output end of the jack is rigidly connected with a pressure sensor. A fastening plate is arranged at the output end of the jack. The fastening plate is fixedly connected to the first installation plate through a bolt assembly. A connecting screw is threadedly connected inside the fastening plate, and the end of the connecting screw is connected to the second installation plate. The jack adopts an electro-hydraulic structure, replacing the traditional manual jack, which can achieve stepless adjustment of the loading force and adapt to the detection requirements of rollers under different load conditions. The pressure sensor monitors the loading force value in real time and transmits the force value signal to the data acquisition and storage module and the PLC controller in real time. When the loading force reaches the preset value, the loading mechanism automatically stops loading to avoid overloading and damaging the roller.

[0007] More preferably, the inside of the long roller fixing bracket is fixedly connected to the threaded connection holes inside the frame through a bolt assembly. The long roller fixing bracket has an inverted U-shaped structure, and a square tube is welded on the top surface of the long roller fixing bracket. The square tube is fixedly connected to the connecting frame. The structure of the long roller fixing bracket can increase the pressure exerted from top to bottom and disperse the force to the frame, ensuring the bearing capacity and stability of the connecting frame.

[0008] More preferably, the idler roller placement mechanism includes an idler roller bracket and an anti-rolling stop roller. A support plate is welded between two idler roller brackets in the same group, and an anti-rolling stop roller is installed between the support plates. The idler roller bracket is an angled structure plate with an included angle of not less than 90 degrees. The anti-rolling stop roller supports the idler roller to be tested and is adapted to support idler rollers with different diameters for axial movement detection. The angled structure of the idler roller bracket can improve the stability of the idler roller during placement, limit the rolling and radial displacement of the idler roller during the testing process, and keep the idler roller in a horizontal and stable state at all times, providing a precise positioning basis for axial displacement detection.

[0009] More preferably, two handles are fixedly provided on the top of the lead screw, and a concave hexagonal hole is opened on the top surface of the lead screw. Two circular plates are fixedly connected to the outside of the lead screw to facilitate the use of tools such as electric drills to drive the lead screw to rotate. The handles can be used to manually apply pressure to the top of the idler roller to prevent radial displacement of the idler roller, which would lead to inaccurate detection results. At the same time, it also serves as a protective function to prevent the idler roller from falling off. Movable limit plates are fixedly welded to the upper and lower sides of the nut. The movable limit plates are snapped into the inside of the mounting frame. The bottom surface of the lower movable limit plate is provided with an anti-fall limit plate, which abuts against... Above the idler roller to be tested, the roller is radially limited and prevented from falling off. After the lead screw rotates, it drives the nut to move up and down. The moving limit plate limits the nut's directional movement and also limits the distance the nut can move up and down. The mounting frame has a connecting ring inside, which is located between two circular plates outside the lead screw. The connecting ring is fixed inside the mounting frame by a pin. The connecting ring limits the lead screw's rotation to a fixed height. After rotating the lead screw, it ensures that the lead screw rotates at a fixed height, driving the nut to move up and down to adjust the height of the anti-fall-off limit plate.

[0010] More preferably, the displacement sensor adopts a high-precision laser displacement sensor to replace the traditional dial indicator, thereby improving the detection accuracy. The displacement sensor has a displacement conversion module at its end that is flexibly connected to the end of the roller shaft. When the roller is subjected to force and produces axial displacement, it drives the displacement conversion module to make a transverse linear movement along the guide rail. The displacement sensor 701 collects the transverse displacement change data in real time and converts the transverse displacement signal into the roller axial displacement signal through the displacement conversion module, thereby achieving accurate detection of axial displacement.

[0011] More preferably, a tray is provided at the bottom front side of the frame, and a control display platform is mounted on the tray. The bottom front side of the control display platform has feet flush with the bottom surface of the frame. A touch screen, a data acquisition and storage module, a data export interface, and a PLC controller are mounted on the control display platform. The touch screen has operation buttons, an emergency stop button, and an overload alarm module. The display screen on the top surface of the control display platform adopts an inclined structure for easy data reading and operation by the operator. The touch screen is 10.4 inches in size and supports touch operation. The data acquisition and storage module has a storage capacity of 10,000 sets and can store parameters such as loading force values, axial displacement data, and detection time. The data export interface supports both USB 3.0 and Bluetooth 5.0 export methods. The PLC controller adopts... The Siemens S7-1200 series, but not limited to the models mentioned above, achieves coordinated control of the loading mechanism and displacement sensor through circuit design and control component connection. It allows for preset detection processes, supports manual or automatic switching, and enables automated detection and result output display. In case of safety hazards, operators can quickly press the emergency stop button to stop all mechanisms and prevent the accident from escalating. The overload alarm module is linked with the pressure sensor; when the loading force exceeds the preset threshold or the roller displacement is abnormal, it automatically issues an audible and visual alarm to remind operators to handle the situation promptly. This completely solves the problem of low safety in existing devices. Furthermore, through automated control and data integration management, it simplifies the adjustment and reading process, automating the detection process and intelligently processing data, significantly improving detection efficiency and operational convenience.

[0012] Beneficial effects This invention adopts a transverse detection method, and the distance between the long idler roller fixing brackets can be flexibly adjusted. The detection stroke is not constrained by the height of the device. Compared with the existing vertical device, it expands the detection range and can meet the axial displacement detection requirements of large-size idlers and idlers under heavy load conditions. The long idler roller fixing brackets are movable and adjustable, and can be adapted to different models of idlers, significantly improving versatility and solving the problems of small detection range and poor versatility of existing devices.

[0013] In addition, the frame is arranged horizontally, and the overall height is lower than that of the existing vertical devices, which also reduces the floor space occupied. It does not require a large amount of vertical space, which can meet the batch testing needs of the factory, and can also be adapted to the on-site maintenance scenarios with limited space such as underground and small factories, thus solving the problem of limited layout of existing devices.

[0014] In addition, the combined effect of the anti-fall limit plate, emergency stop button, and overload alarm module forms a comprehensive safety protection system, completely eliminating safety hazards such as roller slippage. At the same time, the flexible positioning structure can buffer the impact force, avoiding damage to the roller and equipment, ensuring the personal safety of operators, reducing testing costs, and solving the problem of low safety of existing devices.

[0015] Furthermore, the detection process is automated through a PLC controller. After preset detection parameters, the system can automatically complete operations such as roller positioning, loading, detection, and data storage. A high-precision laser displacement sensor enables real-time acquisition of displacement data, which is displayed on the touch screen in real time. The data can be automatically stored and exported, eliminating the need for manual reading and recording. The loading mechanism adopts electro-hydraulic stepless adjustment, which is easy to operate. Compared with existing devices, it improves detection efficiency and significantly enhances operational convenience, meeting the rapid detection needs of batch rollers and adapting to the pace of modern production lines.

[0016] In addition, the use of high-precision laser displacement sensors and displacement conversion modules improves detection accuracy, which is significantly better than that of traditional dial indicators. The jack can simulate the actual working force state of the idler roller, making the detection data more realistic and reliable. It can be widely used in multiple industries such as mining, ports, and metallurgy, and is suitable for the detection needs of idler rollers of different specifications and working conditions. It has high practicality and promotion value. Attached Figure Description

[0028] In this embodiment, as shown in the appendix Figure 1As shown in the figure, a pallet is provided at the bottom of the front side of the frame 1. A control display placement table 8 is placed on the pallet. At the front side of the bottom of the control display placement table 8, there are feet flush with the bottom surface of the frame 1. A touch screen, a data acquisition and storage module, a data export interface, and a PLC controller are installed on the control display placement table 8. Operation buttons, an emergency stop button, and an overload alarm module are provided on the touch screen. The display screen on the top surface of the control display placement table 8 adopts an inclined structure, which is convenient for operators to read data and operate. The size of the touch screen is 10.4 inches and supports touch operation. The storage capacity of the data acquisition and storage module is 10,000 groups, and it can store parameters such as loading force values, axial displacement data, and detection time. The data export interface supports dual export methods of USB3.0 and Bluetooth 5.0. The PLC controller adopts the Siemens S7-1200 series, but is not limited to the above models. Through circuit design and connection of control components, coordinated control of the loading mechanism 6 and the displacement sensor 701 is achieved. The detection process can be preset, and manual or automatic switching is supported to achieve automated detection and result output display. When there are potential safety hazards, the operator can quickly press the emergency stop button to stop the operation of all mechanisms and avoid the expansion of accidents. The overload alarm module is linked with the pressure sensor. When the loading force exceeds the preset threshold or the displacement of the idler 9 is abnormal, an audible and visual alarm is automatically issued to remind the operator to handle it in time, completely solving the problem of low safety of the existing device. And through automated control and data integration management, the adjustment and reading process are simplified, the detection process is automated, and data processing is intelligent, greatly improving the detection efficiency and operation convenience.

[0029] In this embodiment, as shown in the appendix Figure 3 As shown in the figure, the inside of the long idler fixed bracket 2 is firmly connected to the threaded connection holes inside the frame 1 through bolt assemblies. The long idler fixed bracket 2 has an inverted U-shaped structure, and a square tube is welded to the top surface of the long idler fixed bracket 2. The square tube is fixedly connected to the connecting frame 4. The structure of the long idler fixed bracket 2 can increase the pressure exerted from top to bottom and disperse the force to the frame 1, ensuring the bearing capacity and stability of the connecting frame 4.

[0030] In this embodiment, as shown in the appendix Figure 6 As shown in the figure, two rotating handles 3101 are fixedly provided at the top of the lead screw 31. An inner concave hexagonal hole is opened on the top surface of the lead screw 31. Two round plates are fixedly connected to the outside of the lead screw 31 to facilitate driving the rotation of the lead screw 31 with tools such as an electric drill. The rotating handle 3101 can be used to manually apply pressure to the top of the idler 9 to prevent the radial displacement of the idler 9 from causing inaccurate detection results, and at the same time play a protective role to prevent the idler 9 from falling.

[0031] In this embodiment, as shown in the appendix Figure 6As shown, movable limiting plates 3201 are fixedly welded to the upper and lower sides of the nut 32. The movable limiting plates 3201 are snapped into the inside of the mounting frame 33. The bottom surface of the lower movable limiting plate 3201 is provided with an anti-drop limiting plate 3202. The anti-drop limiting plate 3202 abuts against the roller 9 to be tested, which plays a role in radial limiting and preventing the roller 9 from falling off. After the lead screw 31 rotates, it drives the nut 32 to move up and down. The movable limiting plate 3201 plays a role in limiting the directional movement of the nut 32, and can also limit the distance of the nut 32's up and down movement.

[0032] In this embodiment, as shown in the appendix Figure 6 As shown, the mounting bracket 33 has a connecting ring 3301 inside. The connecting ring 3301 is located between two circular plates outside the lead screw 31, and the connecting ring 3301 is fixedly installed inside the mounting bracket 33 by a pin. The connecting ring 3301 restricts the rotation of the lead screw 31 to a fixed height. After rotating the lead screw 31, it ensures that the lead screw 31 rotates at a fixed height, driving the nut 32 to move up and down to adjust the height of the anti-drop limit plate 3202.

[0033] In this embodiment, as shown in the appendix Figure 3 As shown, the idler roller placement mechanism 5 includes an idler roller bracket 501 and an anti-rolling stop roller 502. A support plate is welded between two idler roller brackets 501 in the same group, and the anti-rolling stop roller 502 is installed between the support plates. The idler roller bracket 501 is an angled structure plate with an included angle of not less than 90 degrees. The anti-rolling stop roller 502 supports the idler roller 9 to be tested and is adapted to support idler rollers 9 with different diameters for axial movement detection. The angled structure of the idler roller bracket 501 can improve the stability of the idler roller 9 when it is placed, limit the rolling and radial displacement of the idler roller 9 during the testing process, and keep the idler roller 9 in a horizontal and stable state at all times, providing a precise positioning basis for axial displacement detection. The anti-rolling stop roller 502 is made of elastic rubber material, which can closely fit the surface of the idler roller 9 to achieve flexible support for the idler roller 9, and at the same time buffer the impact force during the loading process to protect the idler roller 9 from damage.

[0034] In this embodiment, as shown in the appendix Figure 4 and attached Figure 5As shown, a connecting angle plate is welded between the left and right sides of the mounting steel 61. A first mounting plate 6101 and a second mounting plate 6102 are welded to the outside of the connecting angle plate. The first mounting plate 6101 has a vertical through groove inside, with sliding grooves on both sides. The second mounting plate 6102 has two parallel vertical sliding grooves inside. The jack 62 is axially parallel to the idler roller 9. A pressure sensor is rigidly connected to the output end of the jack 62. A fastening plate 6201 is installed at the output end of the jack 62. The fastening plate 6201 is fastened to the first mounting plate 6101 by a bolt assembly. A connecting screw 601 is threaded into the inside of the fastening plate 6201. The end of the connecting screw 601... The jack 62 is connected to the second mounting plate 6102. It adopts an electro-hydraulic structure to replace the traditional manual jack. It can realize stepless adjustment of loading force and adapt to the detection requirements of idler roller 9 under different load conditions. The pressure sensor monitors the loading force value in real time and transmits the force value signal to the data acquisition and storage module and PLC controller in real time. When the loading force reaches the preset value, the loading mechanism 6 automatically stops loading to avoid overload damage to idler roller 9. The loading adjustment module can preset the loading force gradient to realize uniform and graded loading, simulate the stress state of idler roller 9 in actual work, improve the accuracy and reliability of detection data, and greatly improve the convenience of operation compared with the existing manual loading method.

[0035] In this embodiment, as shown in the appendix Figure 2 As shown, the displacement sensor 701 adopts a high-precision laser displacement sensor to replace the traditional dial indicator, thereby improving the detection accuracy. The displacement sensor 701 has a displacement conversion module at its end that is flexibly connected to the end of the idler roller shaft. When the idler roller 9 generates axial displacement after being subjected to force, it drives the displacement conversion module to make a transverse linear movement along the guide rail. The displacement sensor 701 collects the transverse displacement change data in real time and converts the transverse displacement signal into the axial displacement signal of the idler roller through the displacement conversion module, thereby realizing the accurate detection of axial displacement.

[0036] The working process of this embodiment is as follows: First, according to the specifications of the idler roller 9, adjust the spacing of the long idler roller fixing bracket 2, place the idler roller 9 on the idler roller bracket 501, restrict the rolling of the idler roller 9 by the anti-rolling stop roller 502, then flexibly connect the displacement conversion module to the shaft end of the idler roller 9, adjust the position of the displacement sensor 701 to ensure detection accuracy, preset the loading force parameters, detection time, alarm threshold, etc. on the touch screen, and start the detection program; Jack 62 loads the load uniformly and in stages according to preset parameters. Pressure sensors collect the loading force value in real time and transmit it to the data acquisition and storage module and PLC controller. When the loading force reaches the preset value, the loading state is maintained. The idler roller 9, under pressure, generates axial displacement, driving the displacement conversion module to perform lateral movement. Displacement sensor 701 collects the lateral displacement data in real time, converts it into an axial displacement signal through the displacement conversion module, and transmits it to the touchscreen for real-time display of relevant parameters. The data acquisition and storage module automatically stores the detection data. After the test is completed, the jack 62 will automatically release the force. The test data can be exported via USB or Bluetooth. The operator can use the test data to determine whether the axial displacement of the idler roller 9 meets the standard. If overload or abnormal displacement occurs during the test, the overload alarm module will issue an audible and visual alarm. The operator can press the emergency stop button to stop the test process and check for safety hazards.

[0037] Flexible connection is the opposite of rigid connection. Rigid connection means that there is no displacement between the pressure sensor and the output end of the jack. Flexible connection can use couplings and other measures to achieve power transmission. Various modules such as displacement conversion module are electrically connected through circuit design and basic control elements. Based on the embodiments of the present invention described, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
