Description

Technical Field

[0001] This utility model relates to the technical field of horizontal wheel detection device for yard bridge trolleys, specifically a horizontal wheel detection device for yard bridge trolleys. Background Technology

[0002] The horizontal wheel detection device for a yard crane trolley disclosed in authorization announcement number CN222232059U includes a detection sensor and a detection mechanism. The detection mechanism includes a sensing plate that cooperates with the detection sensor. The sensing plate is mounted on the upper part of a vertically arranged sensing rod. The sensing rod is mounted in a guide tube. The guide tube is vertically installed above the horizontal wheel of the yard crane trolley mechanism. The bottom end of the sensing rod extends out of the bottom end of the guide tube, is located above the horizontal wheel, and contacts the upper end surface of the horizontal wheel.

[0003] When the horizontal wheel mechanism wears down and moves up and down, the horizontal wheel will contact the bottom of the sensing rod, causing the sensing rod to move upward. By detecting the change in the position of the sensing plate by the detection sensor, it is possible to effectively determine whether the horizontal wheel of the trolley mechanism has malfunctioned or is damaged, so as to realize the real-time detection of the status of the horizontal wheel of the trolley mechanism. It can trigger an alarm in the early stage of damage to the horizontal wheel of the trolley, reminding the equipment management personnel to replace the horizontal wheel in time and eliminate potential hazards.

[0004] The technical solution in the prior art document has the function of monitoring and alarming when the horizontal wheel is displaced. However, the device can only be applied to horizontal wheels of a single size. For horizontal wheels of larger yard bridge equipment, it cannot be adapted to the diameter of the horizontal wheel, which affects the accuracy of monitoring. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a horizontal wheel detection device for a yard crane trolley, which solves the problem that it can only be applied to horizontal wheels of a single size specification. For horizontal wheels of larger yard crane equipment, it cannot adapt to the diameter of the horizontal wheel, thus affecting the accuracy of monitoring.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a horizontal wheel detection device for a field bridge trolley, comprising a horizontal wheel, a rotating rod fixedly connected to the side of the horizontal wheel, a bearing sleeved at one end of the rotating rod, a bracket fixedly connected to the side of the bearing, an installation hole provided at the top of the bracket and an installation bolt provided in the installation hole, a monitoring component fixedly connected to the bottom of the bracket, and a control board fixedly connected to the side of the bracket;

[0007] The monitoring component includes two extension rods fixed symmetrically to the bottom of the bracket. The extension rods are slidably connected to a sleeve. The sleeve has several limiting holes equidistantly opened from top to bottom on its side. The bottom end of the extension rod has a sleeve hole and a spring is sleeved in the sleeve hole. One end of the spring is fixedly connected to a limiting bead that fits into the limiting hole. The bottom end of the sleeve is fixedly connected to a device plate. The surface of the device plate is fixedly connected to a displacement monitor.

[0008] In one specific embodiment, the displacement monitor adopts a non-contact measurement structure, and its transmitting end axis maintains a vertical orientation relationship with the horizontal wheel rim plane.

[0009] In one specific embodiment, the limiting hole group on the side of the sleeve includes a plurality of equidistant positioning holes, and the diameter of the limiting bead is adapted to the diameter of the positioning hole.

[0010] In one specific embodiment, the control board integrates a signal processing module and a data storage unit, wherein the signal processing module is configured to convert the detection signal of the displacement monitor.

[0011] In one specific embodiment, the mounting bolts are designed with an anti-loosening structure and equipped with a locking component.

[0012] In one specific embodiment, the surface of the extension rod is provided with scale lines indicating the extension length.

[0013] Compared with the prior art, this utility model provides a horizontal wheel detection device for a yard bridge trolley, which has the following beneficial effects:

[0014] In the technical solution disclosed in this utility model, the adjustable mechanical structure design of the monitoring component enables the displacement monitor to accurately adapt to horizontal wheels of different sizes. At the same time, combined with the intelligent processing function of the non-contact measurement and control board, it achieves high-precision and wide-adaptability horizontal wheel status monitoring.

[0015] The monitoring component designed in this invention, with its sliding fit structure between the extension rod and the sleeve, combined with a spring-driven limiting bead locking mechanism, allows the device board to be adjusted in multiple positions along the axial direction of the extension rod. The locking bead engages with the limiting hole on the side of the sleeve, ensuring the displacement monitor is always aligned with the rim plane of the horizontal wheel, completely resolving the monitoring failure issue caused by differences in the horizontal wheel's dimensions as described in the prior art. Simultaneously, the non-contact measurement characteristic of the displacement monitor maintains a constant vertical distance between its transmitter and the rim of the horizontal wheel, avoiding measurement errors caused by mechanical contact. Combined with the real-time conversion and analysis of displacement data by the integrated signal processing module on the control board, the radial runout of the horizontal wheel can be accurately captured, significantly improving wear monitoring sensitivity. Furthermore, the floating connection between the bracket and the bearing allows the monitoring component to adaptively adjust its angle according to changes in the horizontal wheel's position. The anti-loosening design of the mounting bolts ensures long-term stable fixation of the entire device under vibration. The scale lines on the extension rod surface simplify the positioning operation of the device board, enabling rapid size adaptation and high repeatability monitoring. Attached Figure Description

[0022] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0023] Figures 1-4As an embodiment of this utility model, a horizontal wheel detection device for a field bridge trolley includes a horizontal wheel 1, a rotating rod 2 fixedly connected to the side of the horizontal wheel 1, a bearing 3 sleeved at one end of the rotating rod 2, a bracket 4 fixedly connected to the side of the bearing 3, an installation hole with an installation bolt 5 in the top of the bracket 4, a monitoring component 6 fixedly connected to the bottom of the bracket 4, and a control plate 7 fixedly connected to the side of the bracket 4.

[0024] The specific problem addressed in this embodiment is that it can only be applied to horizontal wheels of a single size, and cannot accommodate the diameter of horizontal wheels in larger field bridge equipment, thus affecting the accuracy of monitoring. This invention utilizes the adjustable mechanical structure design of the monitoring component 6, enabling the displacement monitor 65 to accurately adapt to horizontal wheels 1 of different sizes. Simultaneously, combined with the intelligent processing function of the non-contact measurement and control board 7, it achieves high-precision and wide-adaptability horizontal wheel status monitoring.

[0025] The monitoring component 6 includes two extension rods 61 that are axially symmetrically fixed to the bottom of the bracket 4. The extension rods 61 are slidably connected to the sleeves 62. The sleeves 62 have several limiting holes equidistantly opened from top to bottom on their side. The bottom of the extension rods 61 has a sleeve hole and a spring 66 is sleeved in the sleeve hole. One end of the spring 66 is fixedly connected to a limiting bead 63 that fits into the limiting hole. The bottom of the sleeves 62 is fixedly connected to the equipment plate 64. The surface of the equipment plate 64 is fixedly connected to the displacement monitor 65. In this specific embodiment, the displacement monitor 65 adopts a non-contact measurement structure, and its transmitting end axis maintains a vertical orientation relationship with the rim plane of the horizontal wheel 1. The sliding fit structure between the extension rod 61 and the sleeve 62, combined with the locking mechanism of the limit bead 63 driven by the spring 66, allows the device plate 64 to be adjusted in multiple positions along the axial direction of the extension rod 61. The locking mechanism of the limit bead 63 and the limit hole on the side of the sleeve 62 ensures that the displacement monitor 65 is always aligned with the rim plane of the horizontal wheel 1, completely solving the monitoring failure problem caused by the size difference of the horizontal wheel in the comparison document. At the same time, the non-contact measurement characteristic of the displacement monitor 65 keeps its transmitter end at a constant vertical distance from the rim of the horizontal wheel 1, avoiding measurement errors caused by mechanical contact. Combined with the real-time conversion and analysis of displacement data by the signal processing module integrated in the control board 7, the radial runout of the horizontal wheel 1 can be accurately captured, significantly improving the wear monitoring sensitivity. Furthermore, the floating connection between the bracket 4 and the bearing 3 allows the monitoring component 6 to adaptively adjust its angle according to the position change of the horizontal wheel 1. The anti-loosening design of the mounting bolts 5 ensures that the whole device is stably fixed in a vibration environment for a long time. The scale lines on the surface of the extension rod 61 simplify the positioning operation of the device plate 64, realizing rapid size adaptation and high repeatability monitoring.

[0026] In this specific embodiment, the mounting bolt 5 adopts an anti-loosening structure design and is equipped with a locking component. Specifically, the mounting bolt 5 adopts an anti-loosening structure design and is equipped with a locking component. The specific implementation method is to process a self-locking thread section on the bolt shank and nest an elastic washer and a toothed washer at the nut end to form a double locking component. When the mounting bolt 5 passes through the mounting hole at the top of the bracket 4 and is fixed to the equipment base, the elastic washer is compressed and generates a continuous rebound force, and the meshing teeth of the toothed washer are embedded in the base surface to form a mechanical interlock, effectively resisting the high-frequency vibration during the operation of the field bridge equipment. Its beneficial effect is that through the synergistic effect of the self-locking thread and the double washer, the risk of loosening caused by vibration of traditional bolts is completely eliminated, ensuring the long-term stable fixation of the bracket 4 and the monitoring component 6, and avoiding the distortion of monitoring data caused by installation displacement.

[0027] In this specific embodiment, the surface of the extension rod 61 is provided with scale lines indicating the extension length; specifically, the extension rod 61 is provided with scale lines indicating the extension length by etching a continuously arranged set of millimeter-precision scale lines on the outer wall of the extension rod 61. The scale lines include a reference zero point mark and downwardly increasing numerical markings; when the operator pulls the sleeve 62 to adjust the height of the equipment plate 64, the extension length of the extension rod 61 can be directly read by observing the scale line value aligned with the top of the sleeve 62, and a corresponding relationship can be established with the diameter of the horizontal wheel 1; its beneficial effect is that the precise quantitative positioning of the equipment plate 64 can be achieved through the visual scale lines, and with the locking of the limiting bead 63 and the limiting hole of the sleeve 62, the displacement monitor 65 can quickly adapt to the installation requirements of horizontal wheels 1 of different sizes, while ensuring the consistency of height adjustment of multiple monitoring components 6, and improving the efficiency of batch deployment.

[0028] Working principle: The horizontal wheel 1 floats radially through the rotating rod 2 and the bearing 3. The bracket 4 fixed to the side of the bearing 3 is fixed to the equipment base by the mounting bolts 5. When it is necessary to adapt to different sizes of horizontal wheels 1, the operator pulls down the sleeve 62 to make it slide along the surface of the extension rod 61. After the spring 66 is compressed, it drives the limit bead 63 to disengage from the current limit hole. When the equipment plate 64 is lowered to the target height, the sleeve 62 is released. The spring 66 rebounds and pushes the limit bead 63 into the corresponding limit hole on the side of the sleeve 62 to achieve mechanical locking. At this time, the extension length indicated by the scale line on the surface of the extension rod 61 matches the diameter of the horizontal wheel 1. The displacement monitor 65 transmits detection signals vertically to the wheel rim plane of the horizontal wheel 1 in a non-contact manner. The real-time collected displacement data is converted into radial runout by the signal processing module of the control board 7. The data storage unit continuously records the monitoring results. When the wear of the horizontal wheel 1 causes the radial displacement to exceed the threshold, an alarm is triggered.

[0029] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field.
