Description

Technical Field

[0001] This utility model relates to the field of rail transit technology, and in particular to a monitoring device for rail transit. Background Technology

[0002] Rail transit refers to a type of transportation vehicle or transport system that requires operating vehicles to run on specific tracks. During the operation of rail transit, stable monitoring is required with the help of communication and monitoring equipment. Existing monitoring devices generally adopt a fixed structure with flanges and bolts. Conventional installation requires multiple bolts, and in order to ensure stability in a vibration environment, this directly leads to multiple obstacles in the disassembly process.

[0003] The core requirements for equipment maintenance in the rail transit industry are short timeliness, high efficiency, and no disruption to operations. However, the inefficiency of bolt installation directly disrupts this balance. From the maintenance process perspective, bolt removal involves multiple tedious steps such as tool preparation, climbing to heights, rust removal, and disassembly and component removal, which takes a long time overall. If abnormal situations such as stripped bolt threads or corrosion are encountered, the time consumption will further increase.

[0004] Therefore, it is necessary to provide a new monitoring device for rail transit to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a monitoring device for rail transit.

[0006] This utility model provides a monitoring device for rail transit, including a mounting base and multiple snap-fit ​​plates. The mounting base has an angle adjustment component at its bottom end that drives the fixed plate to rotate. Two side fixed plates are fixedly connected to both sides of the fixed plate. Two snap-fit ​​grooves are opened on the adjacent side of the two side fixed plates. Two electric cylinders are respectively provided on both sides of the inner wall of the monitoring lens compartment. The output ends of the two electric cylinders pass through the monitoring lens compartment and are fixedly connected to two snap-fit ​​cylinders. The snap-fit ​​cylinders are provided with a driving component for driving the multiple snap-fit ​​plates to move closer and further apart.

[0007] Preferably, the angle adjustment assembly includes a gear assembly, a rotary limiting disk, a fixed frame, a drive motor and a motor shaft. A rotary limiting groove is provided on the lower surface of the mounting base. One end of the rotary limiting disk is rotatably connected inside the rotary limiting groove. The fixed frame is fixedly connected to the lower surface of the mounting base. The drive motor is also fixedly connected to the lower surface of the mounting base. The output end of the drive motor is connected to the motor shaft. The motor shaft is rotatably connected to the fixed frame. A gear assembly is provided between the motor shaft and the rotary limiting disk.

[0008] Preferably, the gear assembly includes a driving gear and a driven gear. The driving gear is sleeved on the outer surface of the motor shaft, and the driven gear is fixedly connected to the end of the rotating limiting disk away from the rotating limiting groove. The end of the rotating limiting groove away from the rotating limiting disk is fixedly connected to the fixing plate.

[0009] Preferably, the drive assembly includes a transmission assembly, a second transmission motor, a second motor shaft, and multiple snap-fit ​​plates. A gear cavity is provided inside the snap-fit ​​cylinder, and the second transmission motor is embedded inside the snap-fit ​​cylinder. The output end of the second transmission motor is connected to one end of the second motor shaft, and the other end of the second motor shaft is rotatably connected to one side wall of the gear cavity. Multiple guide grooves are arranged in a circular array on the outer side of the snap-fit ​​cylinder, and multiple snap-fit ​​plates are slidably connected inside the multiple guide grooves. A transmission assembly is provided between the second motor shaft and the multiple snap-fit ​​plates.

[0010] Preferably, the transmission component includes a transmission gear, on which multiple guide arc grooves are formed in a circumferential array, and one end of multiple snap-fit ​​plates is slidably connected inside the multiple guide arc grooves.

[0011] Preferably, a monitoring lens is provided on one side of the monitoring lens compartment, and multiple heat dissipation holes are provided on the side of the monitoring lens compartment away from the monitoring lens.

[0012] Compared with related technologies, the monitoring equipment for rail transit provided by this utility model has the following advantages:

[0013] The drive assembly moves multiple snap-fit ​​plates together and apart. When the snap-fit ​​plates are close together, they release their contact with the inner wall of the snap-fit ​​groove and simultaneously release the snap-fit ​​between the snap-fit ​​cylinder and the side fixing plate, making it easy to remove the monitoring lens compartment. When the snap-fit ​​plates are apart, they contact the inner wall of the snap-fit ​​groove and simultaneously lock the snap-fit ​​between the snap-fit ​​cylinder and the side fixing plate, making it easy to fix the monitoring lens compartment. This eliminates the cumbersome process of bolt removal and saves time-consuming steps such as tool preparation and rust removal, greatly improving maintenance efficiency. The maintenance team can handle more faulty cameras within the limited track maintenance window, without having to repair them step by step in multiple windows. Attached Figure Description

[0023] In the specific implementation process, such as Figure 1-6 As shown, the device includes a mounting base 1 and multiple snap-fit ​​plates 407.

[0024] In the specific implementation process, such as Figure 2 As shown, the angle adjustment assembly includes a gear assembly, a rotating limiting disk 203, a fixed frame 101, a drive motor 104, and a motor shaft 105. A rotating limiting groove 102 is formed on the lower surface of the mounting base 1, and one end of the rotating limiting disk 203 is rotatably connected inside the rotating limiting groove 102. The fixed frame 101 is fixedly connected to the lower surface of the mounting base 1, and the drive motor 104 is also fixedly connected to the lower surface of the mounting base 1. The output end of the drive motor 104 is connected to the motor shaft 105, and the motor shaft 105 is rotatably connected to the fixed frame 101. A gear is provided between the motor shaft 105 and the rotating limiting disk 203. The angle adjustment assembly includes a gear assembly, a rotary limiting disk 203, a fixed frame 101, a drive motor 104, and a motor shaft 105. A rotary limiting groove 102 is provided on the lower surface of the mounting base 1. One end of the rotary limiting disk 203 is rotatably connected inside the rotary limiting groove 102. The fixed frame 101 is fixedly connected to the lower surface of the mounting base 1. The drive motor 104 is also fixedly connected to the lower surface of the mounting base 1. The output end of the drive motor 104 is connected to the motor shaft 105. The motor shaft 105 is rotatably connected to the fixed frame 101. A gear assembly is provided between the motor shaft 105 and the rotary limiting disk 203.

[0025] The drive motor 104 drives the motor shaft 105 to rotate the drive gear 103. The drive gear 103 meshes with and drives the driven gear 202 to rotate synchronously. Then, the driven gear 202 synchronously drives the rotating limit disk 203 and the fixed plate 2 to rotate. The rotating limit disk 203 assists the rotation of the driven gear 202 and the fixed plate 2 inside the rotating limit groove 102. Then, the fixed plate 2 drives the monitoring lens compartment 3 to adjust its angle through the two side fixed plates 201.

[0026] In the specific implementation process, such as Figure 3-6 As shown, the drive assembly includes a transmission assembly, a second transmission motor 402, a second motor shaft 403, and multiple snap-fit ​​plates 407. A gear cavity 401 is provided inside the snap-fit ​​cylinder 4, and the second transmission motor 402 is embedded in the snap-fit ​​cylinder 4. The output end of the second transmission motor 402 is connected to one end of the second motor shaft 403, and the other end of the second motor shaft 403 is rotatably connected to one side wall of the gear cavity 401.

[0027] The monitoring lens compartment 3 uses a combination of multiple fans 304 and multiple heat dissipation holes 305 to ensure that the core computing unit can still work normally under extreme temperatures.

[0028] The working principle of this utility model is as follows: The second drive motor 402 drives the second motor shaft 403 to drive the multiple guide arc grooves 405 to drive the multiple snap-fit ​​plates 407 away from the inner wall of the snap-fit ​​groove 204 along the multiple guide grooves 406, thereby activating the electric cylinder 303 to drive the snap-fit ​​cylinder 4 to disengage from the snap-fit ​​groove 204, so that the operator can easily remove the monitoring lens compartment 3. By reversing the above operation, the multiple snap-fit ​​plates 407 can abut against the inner wall of the snap-fit ​​groove 204 along the multiple guide grooves 406.

[0029] The circuits and controls involved in this utility model are all existing technologies and will not be described in detail here.
