Abstract
Description
Technical Field
[0001] This utility model relates to the field of abnormal parts detection technology, specifically an abnormal parts positioning device. Background Technology
[0002] During subway operation and maintenance, abnormal parts location and detection components are often used to collect images of parts on both sides and the bottom of subway vehicles. These images are then compared and analyzed with the preset standard parts status parameters in the database to accurately determine whether there are abnormalities such as wear or looseness in the parts. This method greatly improves the efficiency and accuracy of subway parts maintenance.
[0003] However, most existing subway parts detection devices are installed in tunnels on both sides of the track. When a train passes by at high speed, the strong airflow it generates will carry away debris such as gravel and dust from the surrounding area of the track, which can easily scratch the lens of the device and damage the sensor. This will not only lead to distorted detection data, but also seriously affect the service life of the device. Therefore, it is urgent to optimize the structure and redesign the abnormal parts positioning device to effectively avoid the above-mentioned damage problems. Utility Model Content
[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide an abnormal part positioning device with the advantage of good protection effect.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an abnormal part positioning device, comprising a base plate, an abnormal part positioning assembly disposed above the base plate, a drive box fixedly connected to the top of the base plate, a slider slidably connected inside the drive box, a threaded rod rotatably connected inside the drive box, the threaded rod being threadedly connected to the slider, a motor fixedly connected to the top of the drive box, the output end of the motor being fixedly connected to the threaded rod, a protective cover fixedly connected to the right side of the slider, the abnormal part positioning assembly being located inside the protective cover, sleeves fixedly connected to the four corners of the front and back of the protective cover, a limit rod slidably connected inside the sleeve, a protective plate fixedly connected to the end of the limit rod away from the protective cover, and springs fixedly connected to the four sides of the front and back of the protective cover, the end of the spring away from the protective cover being fixedly connected to the protective plate.
[0006] In a preferred embodiment of this utility model, a support column is fixedly connected to the top of the base plate, a groove is provided on the top of the support column, and a movable column is slidably connected inside the groove. A support frame is fixedly connected to the top of the movable column, and slots are provided on the surface of the movable column. The number of slots is several, and bolts are threaded inside the support column, and the bolts are inserted into the slots.
[0007] As a preferred embodiment of this utility model, the support frame has a movable block hinged inside, the movable block is fixedly connected to the abnormal part positioning component, and the surface of the support frame is provided with a locking screw, which is used in conjunction with the movable block.
[0008] As a preferred embodiment of this invention, a supplementary light is fixedly connected to the right side of the support column.
[0009] As a preferred embodiment of this utility model, buffers are fixedly connected to the upper and lower sides of the front and back of the protective cover, and the end of the buffer away from the protective cover is fixedly connected to the protective plate.
[0010] As a preferred embodiment of this utility model, mounting brackets are fixedly connected to all four sides of the bottom of the base plate, and mounting brackets have mounting openings on their surfaces.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] 1. This utility model adopts a multi-protective structure combining a protective cover and a protective plate, along with an elastic buffer design of springs and dampers, which can effectively disperse and absorb external impact forces. When a train passes at high speed, the protective plate first contacts the debris carried by the airflow, and the springs and dampers convert the impact force into elastic potential energy, significantly reducing the impact of the impact force on the positioning components of abnormal parts. This design not only protects the precision testing equipment but also reduces testing interruptions and maintenance costs caused by equipment damage, ensuring the long-term stable operation of the device. Simultaneously, the sliding connection structure between the sleeve and the limiting rod ensures the stability of the protective plate under force, preventing it from shifting or shaking, further improving the protective effect. This device has the advantage of excellent protective performance.
[0013] 2. This utility model utilizes an adjustable structure of the support column and movable column, combined with a locking mechanism of slots and bolts, to make the height adjustment of the abnormal part positioning component more flexible and convenient. By loosening the bolts and moving the movable column to the appropriate position, and then retightening the bolts to fix it, it can quickly adapt to the inspection needs of different types of subway vehicles. This design not only improves the versatility of the device but also ensures that the positioning component is always at the optimal inspection height, improving the quality and accuracy of image acquisition. In addition, the multiple slots provide more height adjustment options, meeting the precise adjustment needs in different scenarios. Attached Figure Description

Detailed Implementation
[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] like Figures 1 to 4 As shown, an abnormal part positioning device includes a base plate 1, an abnormal part positioning assembly 5 disposed on the top of the base plate 1, a drive box 2 fixedly connected to the top of the base plate 1, a slider 3 slidably connected inside the drive box 2, a threaded rod rotatably connected inside the drive box 2, the threaded rod being threadedly connected to the slider 3, a motor 4 fixedly connected to the top of the drive box 2, the output end of the motor 4 being fixedly connected to the threaded rod, a protective cover 6 fixedly connected to the right side of the slider 3, the abnormal part positioning assembly 5 being located inside the protective cover 6, sleeves 7 fixedly connected to the four corners of the front and back of the protective cover 6, a limit rod 8 slidably connected inside the sleeves 7, the end of the limit rod 8 away from the protective cover 6 being fixed. A protective plate 9 is connected to the protective cover 6. Springs 16 are fixedly connected to the front and back sides of the protective cover 6. The end of the spring 16 away from the protective cover 6 is fixedly connected to the protective plate 9. The slider 3 slides up and down in the drive box 2. In actual use, there are two sets of this device, which are installed on both sides of the subway track respectively. The abnormal part positioning component 5 detects the subway on the subway track. The above-mentioned abnormal part positioning component 5 and motor 4 are common existing technologies and are common knowledge to those skilled in the art. This application will not elaborate on them. The relevant contents not disclosed in this application, such as the dustproof treatment of the threaded rod and the control system of the motor 4, are common knowledge to those skilled in the art. This application will not elaborate on them one by one.
[0021] refer to Figure 3A support column 10 is fixedly connected to the top of the base plate 1. The top of the support column 10 is provided with a groove, and a movable column 11 is slidably connected inside the groove. A support frame 13 is fixedly connected to the top of the movable column 11. The surface of the movable column 11 is provided with slots, and there are several slots. A bolt 12 is threaded inside the support column 10, and the bolt 12 is inserted into the slot.
[0022] As a technical optimization of this utility model, the adjustable structure of the support column 10 and the movable column 11, combined with the locking method of the slot and bolt 12, makes the height adjustment of the abnormal part positioning component 5 more flexible and convenient. By loosening the bolt 12 and moving the movable column 11 to the appropriate position, and then retightening the bolt 12 to fix it, it can quickly adapt to the detection needs of different types of subway vehicles. This design not only improves the versatility of the device, but also ensures that the positioning component is always at the optimal detection height, improving the quality and accuracy of image acquisition. In addition, the setting of several slots provides more height adjustment options to meet the precise adjustment needs in different scenarios.
[0023] refer to Figure 4 The support frame 13 has a hinged movable block 14 inside, which is fixedly connected to the abnormal part positioning assembly 5. The surface of the support frame 13 is provided with a locking screw 15, which works in conjunction with the movable block 14.
[0024] As a technical optimization of this utility model, the movable block 14 inside the support frame 13 cooperates with the locking screw 15 to achieve multi-angle adjustment of the abnormal part positioning component 5. By loosening the locking screw 15, the movable block 14 can be freely rotated to the desired angle, and then the screw can be tightened to lock the position, allowing the abnormal part positioning component 5 to flexibly align with different parts of the subway vehicle. This design enhances the adaptability of the device, enabling precise detection of different parts on both sides and the bottom of the vehicle. At the same time, the fixing method of the locking screw 15 ensures the stability of the movable block 14 during the detection process, guaranteeing the reliability of the detection results.
[0025] refer to Figure 3 A supplementary light 20 is fixedly connected to the right side of the support column 10.
[0026] As a technical optimization of this utility model, the addition of the supplementary light 20 effectively improves the lighting conditions of the inspection environment, especially in low-light scenarios such as tunnels, significantly enhancing the image acquisition effect of the abnormal part positioning component 5. Sufficient light makes the details on the part surface clearer, helping the system to more accurately identify abnormalities such as wear and looseness. This not only improves the accuracy of inspection but also reduces misjudgments or missed detections caused by insufficient light. The reasonable installation position of the supplementary light 20 ensures that the light can be evenly irradiated in the inspection area, avoiding shadows or reflections, further optimizing the inspection environment.
[0027] refer to Figure 2 The front and back sides of the protective cover 6 are fixedly connected with buffers 17, and the end of the buffer 17 away from the protective cover 6 is fixedly connected to the protective plate 9.
[0028] As a technical optimization of this utility model, the addition of buffer 17 further enhances the buffering and shock absorption performance of the protective plate 9. Working in conjunction with the spring 16, it can more effectively absorb and disperse impact forces. When the protective plate 9 is impacted, the buffer 17, through its internal damping structure, slows down the transmission speed of the impact force, prolonging the impact time and thus reducing the force acting on the positioning components per unit time. This dual buffer design greatly improves the device's impact resistance and protects internal precision components from damage. Simultaneously, the stable performance of the buffer 17 ensures that the protective system maintains good working condition after multiple impacts, improving the reliability and durability of the device.
[0029] refer to Figure 1 The bottom of the base plate 1 is fixedly connected to the four sides of the bottom with mounting brackets 18, and the surface of the mounting brackets 18 is provided with mounting openings 19.
[0030] As a technical optimization of this utility model, the mounting bracket 18 and mounting port 19 at the bottom of the base plate 1 facilitate the installation and fixation of the device. The mounting port 19 allows the device to be securely installed at suitable positions on both sides of the track, and the multiple mounting ports 19 increase the flexibility and stability of the installation. This design not only facilitates the quick installation and disassembly of the device but also ensures its stability under the vibration environment generated by train movement. A stable installation foundation is a prerequisite for ensuring the accurate detection of the abnormal parts positioning component 5, avoiding detection errors caused by device shaking, and improving the reliability of the detection results.
[0031] The working principle and usage process of this utility model are as follows: Before use, check the installation status of the mounting bracket 18 at the bottom of the base plate 1 to ensure that the mounting bracket 18 is firmly connected without any signs of loosening, and that the connection structure at the mounting port 19 is reliable. Check whether each component of the device is intact, whether the surface of the protective cover 6 is undamaged, whether the spring 16 and the buffer 17 between the protective plate 9 and the protective cover 6 are deformed, and whether the limiting rod 8 inside the sleeve 7 slides smoothly. At the same time, check the connection between the support column 10 and the movable column 11, whether the bolt 12 is tightly inserted into the slot, whether the supplementary light 20 can be lit normally, and whether the wiring connection of the motor 4 and the abnormal parts positioning component 5 is secure. When using, first loosen the bolt 12 on the support column 10 according to the height of the subway vehicle to be tested, adjust the position of the movable column 11 in the groove of the support column 10, and after the support frame 13 reaches the appropriate height, reinsert the bolt 12 into the corresponding slot and tighten it to fix it. Next, loosen the locking screws 15 on the surface of the support frame 13, rotate the movable block 14 fixedly connected to the abnormal part positioning component 5, adjust the detection angle of the abnormal part positioning component 5, and tighten the locking screws 15 after the angle is appropriate to fix the movable block 14 to the support frame 13. When the subway has not completely stopped, it is in motion, and the airflow can easily carry away gravel. At this time, the position of the protective cover 6 is as shown in the attached figure. Figure 1 As shown, the device is in the closed state, thus protecting the abnormal part positioning component 5. If there is external debris or airflow impact, the protective plate 9 will be subjected to force first and move towards the protective cover 6 under the limiting action of the sleeve 7 and the limiting rod 8. The spring 16 and the buffer 17 will be compressed to generate elastic force, which will absorb and buffer the impact force, protecting the abnormal part positioning component 5 from damage. At the same time, the protective cover 6 can effectively protect the abnormal part positioning component 5. After the subway stops, the motor 4 is started. The output end of the motor 4 drives the threaded rod in the drive box 2 to rotate. The slider 3, which is threadedly connected to the threaded rod, slides in the drive box 2. The protective cover 6 on the right side of the slider 3 moves upward with the slider 3, gradually revealing the abnormal part positioning component 5 located inside the protective cover 6, and then the parts at the bottom of both sides of the subway are inspected. Then, the supplementary light 20 is turned on to provide sufficient light for the inspection area.
