Description

Technical Field

[0001] The utility model relates to a monitoring device, and more specifically, to a track-type video monitoring device. Background Art

[0002] Existing track-mounted monitoring devices typically include a monitoring camera and running wheels positioned above the camera to engage with the upper surface of the track. When the monitoring device moves on the track, it is prone to shaking, causing the running wheels to deviate from parallel to the track, resulting in a jam and inability to move forward. Currently, to prevent the running wheels from deviating from their path, the monitoring device is usually equipped with limiting wheels that engage with the side of the track to limit their position. However, the limiting wheels will wear out over time, and after a long period of use, shaking will still occur, causing the running wheels to deviate from their path. Utility Model Content

[0003] The purpose of the present invention is to address the deficiencies of the prior art and to provide a track-type video surveillance device with a simple structure and the ability to advance parallel to a track.

[0004] The technical solution of the utility model is implemented as follows: a track-type video monitoring device includes a track and a chassis, the upper end of the chassis is provided with a pulley mounted on the track, the lower end of the chassis is provided with a monitoring head, and a battery module is provided in the chassis.

[0005] A mounting bracket is provided in the chassis above the battery module. A driving wheel that cooperates with the vertical side wall on one side of the track is provided on the mounting bracket through a driving assembly, and a driven wheel is provided on the mounting bracket on the other side of the track; a tensioning assembly is provided on the mounting bracket for cooperating with the driving wheel and the driven wheel to clamp the track.

[0006] In the above-mentioned track-type video surveillance device, the driving assembly includes a bearing seat arranged on the mounting brackets on both sides of the track, a rotating shaft is provided in the bearing seat through at least one bearing, and the driving wheel is installed on the upper end of the rotating shaft.

[0007] A drive motor is provided on the mounting bracket, the output shaft of the drive motor is connected to a drive wheel through a gearbox, a pulley is provided at the lower end of the rotating shaft, and the drive wheel and the pulley are connected by a transmission belt.

[0008] In the above-mentioned track-type video surveillance device, the mounting bracket on one side of the driving wheel is provided with an adjustment long hole perpendicular to the track direction, a mounting bolt is provided in the adjustment long hole, and a tensioning adjustment wheel that cooperates with the transmission belt is provided at the lower end of the mounting bolt.

[0009] In the above-mentioned track-type video surveillance device, the tensioning assembly includes two guide rods arranged on the mounting bracket and perpendicular to the track direction, a sliding mounting seat is provided between the two guide rods, and the driving assembly is provided on the sliding mounting seat; a baffle is provided at the free end of the guide rod, and a tensioning spring is provided between the baffle and the sliding mounting seat.

[0010] In the above-mentioned rail-type video surveillance device, at least two pulleys are provided and are symmetrically arranged along the length direction of the rail. A fixing ear for hoisting and fixing is provided on the upper surface of the rail, and the fixing ear is located between the two symmetrical pulleys.

[0011] With this structure, the driving wheel is positioned on the side of the track. Even if the upper pulley shifts, its forward direction remains parallel to the length of the track, effectively preventing the occurrence of jamming caused by pulley shifting. Furthermore, the self-tensioning assembly ensures that the driving and driven wheels are always clamped to the track, effectively reducing shaking during movement. This further prevents pulley shifting while maintaining camera stability and ensuring clear surveillance footage. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] See Figure 1-5 As shown, the present invention provides a track-mounted video surveillance device comprising a track 1 and a chassis 2. The chassis 2 has a pulley 3 mounted on the track 1 at its upper end, a monitoring head 4 at its lower end, and a battery module 5 within the chassis 2. The monitoring head is connected to an external control terminal for real-time monitoring or video recording. The connection method can be conventional in the art. In this embodiment, an antenna is used for wireless transmission. The specific structure is common knowledge to those skilled in the art and will not be described in detail here.

[0020] A mounting bracket 6 is installed within the chassis 2 above the battery module 5. A driving pulley 8 is mounted on the mounting bracket 6 via a drive assembly 7, engaging the vertical sidewall of one side of the track 1. A driven pulley 9 is mounted on the mounting bracket 6 on the other side of the track 1. A tensioning assembly 10 is also installed on the mounting bracket 6, which is used to securely clamp the driving and driven pulleys 8 and 9 to the track 1. By placing the driving pulley on the side of the track, even if the upper pulley deviates, its forward direction remains parallel to the length of the track, effectively preventing jamming caused by pulley deviation due to shaking.

[0021] In addition, the tensioning assembly enables the driving wheel and the driven wheel to always clamp the track, which can effectively reduce the shaking of the monitoring device during movement, further avoid the pulley offset, and maintain the stability of the camera, ensuring the clarity of the monitoring video.

[0022] In this embodiment, the drive assembly 7 preferably includes a bearing seat 7a mounted on mounting brackets 6 on both sides of the track 1. A rotating shaft 7b is disposed within the bearing seat 7a via at least one bearing, and the driving wheel 8 is mounted on the upper end of the rotating shaft 7b. In this embodiment, two bearings are provided within the bearing seat to secure the upper and lower proximal ends of the rotating shaft, respectively, thereby improving the stability of the rotating shaft.

[0023] Mounting bracket 6 is equipped with a drive motor 7c. Its output shaft is connected to a drive wheel 7d via a gearbox. A pulley 7e is located at the lower end of a rotating shaft 7b, connected to the drive wheel 7d and pulley 7e via a transmission belt 7f. The drive motor is a servo motor and is connected to an external control terminal. The speed and direction of the drive motor are adjusted according to monitoring requirements, allowing the monitoring device to move forward, backward, or stop along the track in the desired direction.

[0024] Furthermore, the mounting bracket 6 on one side of the drive wheel 7d is provided with an adjustment slot 7g perpendicular to the direction of the track 1. A mounting bolt 7h is installed within the adjustment slot 7g. A tensioning wheel 7i is provided below the mounting bolt 7h to engage with the drive belt 7f. The tensioning wheel keeps the drive belt taut at all times, preventing the drive wheel from spinning idly due to the belt becoming loose, thereby ensuring effective transmission.

[0025] In this embodiment, the tensioning assembly 10 comprises two guide rods 10a mounted on the mounting bracket 6 and perpendicular to the track 1. A sliding mount 10b is positioned between the two guide rods 10a, and the driving assembly 7 is mounted on the sliding mount 10b. A baffle 10c is positioned at the free end of the guide rods 10a, and a tensioning spring 10d is positioned between the baffle 10c and the sliding mount 10b. The baffle and the tensioning spring cooperate to press the sliding mount against the track, ensuring that the driving wheel maintains close contact with the track surface and reducing shaking of the monitoring device during movement.

[0026] In this embodiment, at least two pulleys 3 are provided and are symmetrically arranged along the length of the track. A fixing lug 11 for hanging and fixing is provided on the upper surface of the track 1. The fixing lug 11 is located between the two symmetrical pulleys 3. This structure ensures the installation of the track and the movement of the pulleys on the track, avoiding interference between the two.

[0027] When in use, the drive motor is started to provide power to the active wheel, and the tensioning spring cooperates with the baffle to press the sliding mount toward the track, so that the active wheel can always be close to the track surface, and the pulley moves along the track, and video monitoring is performed under the track path through the monitoring head.
