Description

Technical Field

[0001] This utility model belongs to the field of train integrated wireless communication technology, and relates to a locomotive CIR on-the-road monitoring device that is easy to maintain. Background Technology

[0002] In the railway transportation sector, locomotive CIR (Continuous In-Ride Monitoring) equipment is a crucial component ensuring the safe and stable operation of locomotives. It is primarily used to monitor various parameters and status information during locomotive operation in real time and promptly report this information to relevant control systems or personnel, providing essential data for locomotive scheduling, maintenance, and troubleshooting. However, some existing CIR monitoring devices have structural design flaws, causing numerous inconveniences in practical use and maintenance.

[0003] On the one hand, the housing and internal components of existing CIR in-transit monitoring equipment are usually fixedly connected by multiple bolts. When the equipment needs maintenance due to malfunction or routine inspection, the staff must remove these bolts one by one in order to pull the internal components out of the housing for operation. This fixing method makes the maintenance process time-consuming and laborious, seriously affecting the maintenance efficiency. At the same time, during frequent disassembly and installation, the bolts are prone to loosening or even being lost, which not only affects the normal assembly of the equipment, but may also pose a potential threat to the operational stability of the equipment.

[0004] On the other hand, during the use of CIR in-transit monitoring equipment, multiple lines with different functions need to be connected to achieve data transmission, power supply and other functions. Due to the complex locomotive operating environment, these connecting harnesses are inevitably affected by factors such as vibration and external pulling. After long-term use, they are prone to loosening. Loose lines can lead to problems such as unstable signal transmission and power outage. In severe cases, the monitoring equipment may not be able to work properly, which will affect the accurate monitoring and judgment of the locomotive's operating status and pose a hidden danger to railway transportation safety. Utility Model Content

[0005] The technical problem this utility model aims to solve is that workers must disassemble these bolt fasteners one by one in order to pull the internal components out of the housing for operation. This fixing method makes the maintenance process time-consuming and laborious, seriously affecting maintenance efficiency. In addition, the locomotive operating environment is complex, and these connecting harnesses are inevitably affected by factors such as vibration and external pulling. After long-term use, they are prone to loosening. Loose wiring can lead to problems such as unstable signal transmission and power outage.

[0006] The present invention provides a locomotive CIR on-the-road monitoring device that facilitates subsequent maintenance, comprising a chassis and an inner shell. The chassis has an opening on one side, and the inner shell extends to the outside of the chassis and is fixedly connected to a panel. The fixing component is located on the side of the panel opposite to the chassis, near the two end faces. The fixing component is used to fix the position of the inner shell. The fixing component also includes a stabilizing mechanism, which is used in conjunction with the panel.

[0007] Preferably, the fixing assembly includes a mounting plate, a positioning rod, a fixing block, a limiting block, a movable plate, and a connecting rod. The mounting plate is fixedly connected to both end faces of the side of the panel opposite to the chassis. The positioning rod is symmetrically and movably connected to the side of the mounting plate away from the chassis. The fixing block is symmetrically and fixedly connected to the end face of the chassis opposite to the mounting plate, and the fixing block abuts against the positioning rod. A movable plate is provided on the end face of the mounting plate away from the chassis. A connecting rod is symmetrically and movably connected to the end face of the movable plate away from the mounting plate. The end of the connecting rod away from the movable plate is movably connected to the positioning rod. The side of the movable plate away from the chassis passes through the panel and is slidably connected to the panel.

[0008] Preferably, the fixing component further includes a rectangular opening, a rectangular plate, a spring, and a handle opening. The end face of the movable plate has a rectangular opening, and a rectangular plate is disposed inside the rectangular opening. The end face of the rectangular plate away from the movable plate is fixedly connected to the mounting plate. A spring is fixedly connected between the side of the rectangular plate away from the panel and the inside of the rectangular opening. The end face of the movable plate away from the connecting rod has a handle opening.

[0009] Preferably, the stabilizing mechanism includes an inner T-shaped slide rail, a T-shaped slider, a lead screw, a pressure plate, and a movable opening. The inner T-shaped slide rail is fixedly connected to the side of the panel away from the chassis. Several T-shaped sliders are slidably connected to the inner side of the inner T-shaped slide rail. A lead screw is fixedly connected to the side of the T-shaped slider away from the panel. Several pressure plates are provided on the side of the inner T-shaped slide rail away from the panel. A movable opening is provided on one side of the pressure plate, and the lead screw is located inside the movable opening.

[0010] Preferably, the stabilizing mechanism further includes a V-shaped groove, a flange nut, and a lever. The top and bottom of the pressure plate are provided with V-shaped grooves, the end of the lead screw is equipped with a flange nut, and levers are symmetrically fixedly connected to the outer side of the lever.

[0011] Furthermore, the outer side of the inner shell is slidably connected to the inner side of the chassis, and the panel is symmetrically fixedly connected to an arc-shaped handle on the side away from the chassis.

[0012] Compared with the prior art, the beneficial effects of this utility model are: By cooperating with the panel, chassis, mounting plate, positioning rods, movable plate, and springs, the two positioning rods can be made to contact the fixed block when they swing outward, preventing the panel and inner shell from being pulled out. When the movable plate is pulled, the two positioning rods swing inward, disengaging from the fixed block, allowing the panel and inner shell to be pulled out. This effectively solves the problem that workers must disassemble the bolt fasteners one by one before they can pull the internal components out of the casing. Through the cooperation of the inner T-shaped slide rail, T-shaped slider, lead screw and pressure plate, the pressure plate can be slid freely to the place where it is needed. The V-shaped groove on the pressure plate can hold the connecting wire at the end of the plug. By tightening the flange nut, the pressure plate is pushed to press the plug tightly. This effectively solves the problem that these connecting wires are inevitably affected by vibration, external force and other factors, and are prone to loosening after long-term use.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0016] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0017] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0018] Example 1 like Figures 1-6 As shown, the device includes a chassis 1 and an inner shell 3. One side of the chassis 1 is open, and one side of the inner shell 3 extends to the outside of the chassis 1 and is fixedly connected to a panel 2. A fixing component is located on the side of the panel 2 opposite to the chassis 1, near the two end faces. The fixing component is used to fix the position of the inner shell 3. The fixing component also includes a stabilizing mechanism, which works in conjunction with the panel 2. The outer side of the inner shell 3 is slidably connected to the inner side of the chassis 1. A curved handle 22 is symmetrically fixedly connected to the side of the panel 2 away from the chassis 1.

[0019] The chassis 1, inner shell 3, and panel 2 in this technical solution are all existing CIR equipment shells. The electronic components of the CIR equipment are installed inside the inner shell 3. When maintenance is required, the inner shell 3 can be pulled out to expose the components outside the chassis 1. How the electronic components of the CIR equipment are installed inside the inner shell 3 is common knowledge among those in the field, so it will not be described in detail in this technical solution.

[0020] like Figures 1-4 As shown, the fixing assembly includes a mounting plate 4, a positioning rod 5, a fixing block 6, a limiting block 7, a movable plate 8, and a connecting rod 9. Mounting plates 4 are fixedly connected to both end faces of the panel 2 opposite to the chassis 1. Positioning rods 5 are symmetrically and movably connected to the side of mounting plate 4 away from the chassis 1. Fixing blocks 6 are symmetrically and fixedly connected to the end face of the chassis 1 opposite to the mounting plate 4, and the fixing blocks 6 abut against the positioning rods 5. A movable plate 8 is provided on the end face of mounting plate 4 away from the chassis 1. A connecting rod 9 is symmetrically and movably connected to the end face of movable plate 8 away from the mounting plate 4. The connecting rod 9 is located away from the movable plate 8. One end of the movable plate 8 is movably connected to the positioning rod 5. The side of the movable plate 8 away from the chassis 1 passes through the panel 2 and is slidably connected to the panel 2. The fixing assembly also includes a rectangular opening 10, a rectangular plate 11, a spring 12 and a handle opening 13. A rectangular opening 10 is provided on the end face of the movable plate 8. A rectangular plate 11 is provided inside the rectangular opening 10. The end face of the rectangular plate 11 away from the movable plate 8 is fixedly connected to the mounting plate 4. A spring 12 is fixedly connected between the side of the rectangular plate 11 away from the panel 2 and the inside of the rectangular opening 10. A handle opening 13 is provided on the end face of the movable plate 8 away from the connecting rod 9.

[0021] The fixing components can easily fix the positions of the panel 2 and the inner shell 3, which can play a locking role. The surfaces of the positioning rod 5 and the fixing block 6 are in an inclined state, so that when the two positioning rods 5 swing towards the center of the mounting plate 4, there will be no jamming. If necessary, anti-slip pads can be fixed on the surfaces of the positioning rods 5 and the fixing block 6 to increase their friction. The limiting block 7 can limit the maximum angle of the two positioning rods 5 swinging outward.

[0022] Example 2 like Figures 5-6 As shown, the stabilizing mechanism includes an inner T-shaped slide rail 14, a T-shaped slider 15, a lead screw 16, a pressure plate 17, and a movable opening 18. The inner T-shaped slide rail 14 is fixedly connected to the side of the panel 2 away from the chassis 1. Several T-shaped sliders 15 are slidably connected to the inner side of the inner T-shaped slide rail 14. The lead screw 16 is fixedly connected to the side of the T-shaped slider 15 away from the panel 2. Several pressure plates 17 are provided on the side of the inner T-shaped slide rail 14 away from the panel 2. A movable opening 18 is opened on one side of the pressure plate 17. The lead screw 16 is located inside the movable opening 18. The stabilizing mechanism also includes a V-shaped groove 19, a flange nut 20, and a lever 21. V-shaped grooves 19 are opened at the top and bottom of the pressure plate 17. A flange nut 20 is installed at the end of the lead screw 16. Lever 21s are symmetrically fixedly connected to the outer side of the lever 21.

[0023] The stabilizing mechanism can stably fix multiple connecting wires to the interface on the panel 2. One of the pressure plates 17 can fix the plugs of two connecting wires at the same time, or only one connecting wire plug can be fixed. The movable opening 18 is used to adjust the position of the pressure plate 17. When only one plug is fixed, it can accommodate plugs of different thicknesses. Because the V-shaped groove 19 is V-shaped, by adjusting the overall position of the pressure plate 17, the V-shaped groove 19 can accommodate plugs of different thicknesses, making it more convenient to use and increasing its applicability.

[0024] Working Principle: When using this technical solution, first place the chassis 1 in the desired location. The CIR equipment's electronic components are located inside the inner shell 3. When the inner shell 3 and electronic components need to be pulled out for maintenance, firstly, pull the two movable plates 8 simultaneously through the two handle openings 13 to compress the spring 12. Simultaneously, the movable plates 8 pull the positioning rod 5 towards the center of the mounting plate 4 via the connecting rod 9, causing the positioning rod 5 to disengage from the fixed stop 6. Then, the panel 2 and inner shell 3 can be pulled outwards from the chassis 1. Then, maintenance and other operations can be performed on the electronic components inside the inner shell 3. After maintenance is completed, first push the inner shell 3 as a whole towards the chassis 1 to its limit position to release the movable plates 8. Simultaneously, the rebound force of the spring 12 pushes the movable plates 8 and connecting rod 9 to slide towards the positioning rod 5. Simultaneously, the connecting rod 9 pushes the positioning rod 5 to swing outwards and abut against the fixed stop 6. In this way, even when the panel 2 is pulled, the mounting plate 4 and positioning rod 5 will not slip. The above operation can effectively and conveniently fix the position between the panel 2 and the chassis 1.

[0025] After connecting the data cable or power cord to the interface on panel 2, fix it with pressure plate 17. First, you can slide the T-shaped slider 15 freely so that the V-shaped groove 19 on pressure plate 17 is aligned with the end of the data cable plug. Then, put the V-shaped groove 19 on pressure plate 17 onto the end of the plug, and rotate the flange nut 20 forward by using the lever 21. The flange nut 20 pushes pressure plate 17 to press the plug tightly. While pressing the plug, the reaction force fixes the position of T-shaped slider 15, which can effectively fix the data cable or power cord plug and effectively prevent the plug from loosening.

[0026] The descriptions of the orientation and relative positional relationships of the structure in this utility model, such as descriptions of front, back, left, right, up, and down, do not constitute a limitation on this utility model, but are merely for the convenience of description.
