Description

Technical Field

[0001] This utility model belongs to the technical field of vibration monitoring sensor mounting base for rail crane wheels, and specifically relates to a vibration monitoring sensor mounting base for rail crane wheels. Background Technology

[0002] The wheel vibration monitoring sensor mounting bracket for a rail crane is simply a base specifically designed to fix the vibration sensor. Its core function is to ensure that the sensor is installed at the monitoring point, accurately senses the vibration generated when the wheel rotates, and thus transmits the accurate vibration signal back to the monitoring system.

[0003] In existing technologies, vibrations generated by the movement of the rail crane wheels during use can cause the vibration monitoring sensor to loosen, preventing the sensor's detection surface from fully contacting the monitoring point and affecting the accuracy of the detection data. Furthermore, the vibration monitoring sensor requires regular inspection and maintenance, and its disassembly is quite cumbersome. Utility Model Content The purpose of this utility model is to address the shortcomings of existing technologies by proposing a vibration monitoring sensor mounting base for rail crane wheels.

[0004] To achieve the above objectives, this utility model provides a vibration monitoring sensor mounting base for a rail crane wheel, including a hanger. The side of the hanger has several sleeve holes, and a bearing is sleeved inside the sleeve holes. A crane wheel assembly is sleeved inside the bearing, and a slide rail is slidably connected to the surface of the crane wheel assembly. An installation component is provided on the side of the hanger, and a positioning component is provided inside the installation component. A vibration sensor is axially symmetrically arranged at one end of the positioning component. The installation assembly includes a strong magnetic ring magnetically connected to the side of the hanger. A device box is fixedly connected to the side of the strong magnetic ring. A cover plate is fixedly connected to the side of the device box. A control board is fixedly connected inside the cover plate. A communication module is installed inside the control board. The positioning component includes a left side plate fixedly connected to the inner side wall of the device box, a left arc plate fixedly connected to the side of the left side plate in an axisymmetric manner, a right arc plate slidably connected to the side of the left arc plate, a right side plate fixedly connected to the side of the right arc plate, and a spring fixedly connected between the left side plate and the right side plate.

[0005] In the above technical solution, a vibration sensor is further fixedly connected to the back of the right side plate in an axisymmetric manner, and the detection surface of the vibration sensor is in contact with the side of the hanger.

[0006] In the above technical solution, the spring provides a rebound thrust to make the vibration sensor fit against the side of the hanger, and the spring force is less than the magnetic attraction between the strong magnetic ring and the hanger.

[0007] In the above technical solution, the vibration sensor is further electrically connected to the control board, and the control board is configured to send vibration data to the peripheral terminal device through the communication module.

[0008] In the above technical solution, the sliding connection between the left and right arc plates allows the right side plate to move relative to the left side plate to compress or release the spring.

[0009] In the above technical solution, the device box is further detachably connected to the side of the hanger via a strong magnetic ring.

[0010] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model, through the cooperation of the installation component and the positioning component, utilizes the spring between the left and right plates inside the equipment box to provide a continuous rebound thrust. This thrust is transmitted through the right arc plate and the right plate, so that the detection surfaces of the two vibration sensors that are symmetrically fixed to the back of the right plate can be stably and tightly attached to the side of the hanger. This structure effectively overcomes the problem of loose installation caused by the movement and vibration of the crane wheel assembly, ensuring that the vibration sensors always maintain a stable contact state at the monitoring point, thereby significantly improving the accuracy and reliability of vibration data acquisition. 2. This utility model connects the strong magnetic ring in the mounting assembly to the side of the hanger, making the entire equipment box and its internal positioning components and vibration sensor a quick-release unit. When sensor maintenance or replacement is required, the entire detection device can be removed from the hanger simply by overcoming the magnetic force of the strong magnetic ring, making the operation extremely simple and quick. At the same time, the spring force is set to be less than the magnetic force, ensuring the stable adsorption of the device under normal monitoring conditions, thereby greatly simplifying the maintenance process and improving the efficiency of maintenance work.

[0013] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0014] like Figures 1-5 The vibration monitoring sensor mounting base for a track crane wheel shown includes a hanger 1. The side of the hanger 1 has several sleeve holes. A bearing 2 is sleeved inside the sleeve holes. A crane wheel assembly 3 is sleeved inside the bearing 2. A slide rail 4 is slidably connected to the surface of the crane wheel assembly 3. A mounting component 5 is provided on the side of the hanger 1. A positioning component 6 is provided inside the mounting component 5. A vibration sensor 7 is axially symmetrically arranged at one end of the positioning component 6. The mounting component 5 includes a strong magnetic ring 51 magnetically connected to the side of the hanger 1. A device box 52 is fixedly connected to the side of the strong magnetic ring 51. A cover plate 53 is fixedly connected to the side of the device box 52. A control board 54 is fixedly connected inside the cover plate 53. A communication module is installed inside the control board 54. During operation, the entire monitoring device functions as a single unit, connected detachably only to the side of the steel hanger 1 via a strong magnetic ring 51. For maintenance or replacement, personnel simply apply a pulling force sufficient to overcome the magnetic attraction of the strong magnetic ring 51 to the device box 52, allowing for easy and quick removal of the entire device from the hanger 1. It is noteworthy that the preset elastic force of the spring 65 in the positioning assembly 6 is far less than the magnetic attraction of the strong magnetic ring 51. This design ensures that the spring's thrust will not cause the device to loosen or fall off during normal operation. The magnetic connection is only released during manual maintenance, thus perfectly balancing operational stability and ease of maintenance.

[0015] Furthermore, the positioning component 6 includes a left side plate 61 fixedly connected to the inner side wall of the device box 52, a left arc plate 62 fixedly connected to the side of the left side plate 61 in an axisymmetric manner, a right arc plate 63 slidably connected to the side of the left arc plate 62, a right side plate 64 fixedly connected to the side of the right arc plate 63, and a spring 65 fixedly connected between the left side plate 61 and the right side plate 64. During operation, during installation, the equipment box 52 is attracted to the side of the hanger 1 by a strong magnetic ring 51. At this time, the left side plate 61 inside the equipment box 52 is fixed, and the spring 65 connecting the left side plate 61 and the right side plate 64 will release its rebound thrust. This thrust pushes the right side plate 64 and the right arc plate 63 fixed on it to slide along the arc surface of the left arc plate 62 towards the hanger 1, thereby forcing the detection surfaces of the two vibration sensors 7, which are symmetrically fixed to the back of the right side plate 64, to be tightly pressed against the side of the hanger 1 with constant pressure. This continuous and adaptive clamping force effectively eliminates the small gaps that may be caused by vibration, ensuring the integrity and authenticity of vibration signal transmission, thereby realizing high-precision vibration monitoring.

[0016] Furthermore, the vibration sensor 7 is electrically connected to the control board 54, which is configured to send vibration data to a peripheral terminal device via a communication module. During operation, the vibration sensor 7 is electrically connected to the control board 54 fixed inside the cover plate 53 via wires. The control board 54 is configured to receive and process the analog signals collected by the vibration sensor 7 and convert them into digital data. Subsequently, the communication module inside the control board 54 is activated, and the processed vibration data is wirelessly transmitted to the remote terminal device of the peripheral device. Its beneficial effect is that this implementation realizes the real-time acquisition, on-site processing and remote wireless transmission of vibration monitoring data, so that the staff can monitor the running status of the rail crane wheels in real time on the terminal device without being on-site. This greatly improves the automation level and response efficiency of condition monitoring and provides a timely and accurate data foundation for predictive maintenance.

[0017] Furthermore, the sliding connection between the left arc plate 62 and the right arc plate 63 allows the right side plate 64 to move relative to the left side plate 61 to compress or release the spring 65. During operation, the left arc plate 62, fixed to the side of the left side plate 61, and the right arc plate 63, fixed to the side of the right side plate 64, make contact and guide each other through their interlocking arc-shaped sliding surfaces. When the device is installed on the side of the hanger 1, the surface of the hanger 1 generates a reaction force on the vibration sensor 7, pushing the right side plate 64 and the right arc plate 63 to slide along the arc of the left arc plate 62 into the device box 52, thereby smoothly compressing the spring 65 between the left side plate 61 and the right side plate 64. When there is a gap or vibration, the rebound force of the spring 65 pushes the right arc plate 63 and the right side plate 64 to move in the opposite direction through the sliding connection. The beneficial effect is that the sliding connection between the left arc plate 62 and the right arc plate 63 provides precise and stable guidance for the compression and rebound of the spring 65, ensuring that the right side plate 64 can only move in a predetermined straight line, thereby avoiding component jamming or deflection, and enabling the vibration sensor 7 to always apply pressure perpendicular to the detection surface, ensuring the stability and reliability of the fit and detection.

[0018] Working principle: The equipment box 52 is fixed to the side of the hanger 1 by the strong magnetic ring 51. At this time, the spring 65 in the positioning component 6 pushes the right side plate 64, so that the right arc plate 63 slides along the left arc plate 62, thereby pressing the detection surface of the vibration sensor 7 tightly against the surface of the hanger 1. The vibration generated by the crane wheel assembly 3 during operation is transmitted to the vibration sensor 7 through the hanger 1. The sensor converts the vibration signal into an electrical signal and transmits it to the control board 54. After processing the signal, the control board 54 wirelessly sends the data to the remote terminal device through the communication module to realize status monitoring. The elasticity of the spring 65 ensures continuous and stable contact, while the magnetic attraction of the strong magnetic ring 51 ensures the reliability of the overall installation. When maintenance is required, the equipment box 52 can be directly disassembled.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
