A PTZ camera can be installed on both the top and bottom walls of the mounting housing 1, meeting the needs of both ground operation and hoisting. By setting the drive assembly 6 and combining it with the rigid body structure of the mounting housing 1, the load-bearing capacity and operational stability of the track vehicle are significantly improved, making it suitable for shooting requirements in heavy-load scenarios. By setting the power supply component 2, the PTZ camera and the mounting housing 1 can be powered by cables or batteries, ensuring power stability during long-term heavy-load shooting.

The drive main control board 61 is mounted on the bottom surface of the mounting housing 1, the motor mounting plate 62 is mounted on the bottom surface of the mounting housing 1, the drive motor 63 is mounted on the side wall of the motor mounting plate 62, the output end of the drive motor 63 passes through the motor mounting plate 62 and is connected to a motor drive wheel 64, the transmission shaft bracket 65 is mounted on the bottom surface of the mounting housing 1, and the transmission shaft 66 is rotatably connected inside the transmission shaft bracket 65. The transmission shaft 66 passes through the motor mounting plate 62, and the transmission shaft synchronous pulley 661 is mounted on the transmission shaft 66. On the circumferential surface, the synchronous pulley 661 of the drive shaft is connected to the motor drive wheel 64 via a synchronous belt. The drive wheel 662 is mounted on the circumferential surface of the drive shaft 66. The main shaft 67 is rotatably connected inside the mounting housing 1. Both ends of the main shaft 67 protrude through the side wall of the mounting housing 1 and are equipped with drive wheels 5. The main shaft synchronous pulley 671 is mounted on the circumferential surface of the main shaft 67 and is connected to the drive wheel 662 via a synchronous belt. The main shaft pulleys 672 are arranged in pairs and mounted on the circumferential surface of the main shaft 67. The driven shafts 68 are arranged in pairs and rotatably connected to the side wall of the mounting housing 1. One end of the driven shaft 68 protrudes through the side wall of the mounting housing 1 and is equipped with a drive wheel 5. The driven wheels 681 are arranged in pairs and mounted on the circumferential surface of the driven shaft 68. The driven wheels 681 are connected to the main shaft pulleys 672 via a synchronous belt.

[0051] In this embodiment, the location and connection relationship of the driving component 6 are as follows: Figure 4 As shown. The drive control board 61 is used to control the start, stop, speed, and direction of the drive motor 63 according to the received instructions. The rated power of the drive motor 63 is 50W, and the peak power is 400W. The two ends of the drive shaft 66 are rotatably connected to the inside of the drive shaft bracket 65 through bearings, and the rotating shaft is rotatably connected to the motor mounting plate 62 through bearings.

There are two main shaft wheels 672, which are respectively provided at both ends of the main shaft 67 near the sidewalls of the mounting housing 1. There are two driven shafts 68 and driven wheels 681. Bearings are provided on the inner sidewalls of the mounting housing 1, and the driven shaft 68 is rotatably connected to the mounting housing 1 through bearings. A driven shaft 68 bracket is provided on the bottom surface of the mounting housing 1, and the end of the driven shaft 68 located inside the mounting housing is rotatably connected to the driven shaft 68 bracket through a bearing.

[0052] In operation, the drive motor 63 starts, and the motor drive wheel 64 begins to rotate, thereby driving the synchronous belt pulley 661 of the transmission shaft to rotate, which in turn causes the transmission shaft 66 to rotate. At this time, the transmission wheel 662 located on the transmission shaft 66 rotates, thereby driving the synchronous belt pulley 671 of the main shaft connected to it to rotate, which in turn drives the main shaft 67 to rotate, causing the drive wheels 5 located at both ends of the main shaft 67 to rotate. The main shaft pulley 672 on the main shaft 67 will rotate with the rotation of the main shaft 67, thereby driving the driven wheel 681 to rotate, which in turn drives the driven shaft 68 to rotate, causing the drive wheel 5 located on the driven shaft 68 to rotate, realizing the synchronous drive of eight wheels. The motor drive wheel 64 and the synchronous belt pulley 661 of the transmission shaft, the transmission wheel 662 and the synchronous belt pulley 671 of the main shaft, and the main shaft pulley 672 and the driven wheel 681 are all connected by synchronous belts to achieve stepless power transmission, reducing mechanical losses and improving transmission efficiency. Combined with the high-performance drive motor 63, this utility model has a fast response, quiet operation, independently adjustable acceleration and deceleration curves, and no shaking during start and stop. By setting up a drive shaft synchronous pulley 661, a drive wheel 662, a main shaft synchronous pulley 671, a main shaft wheel 672, and a driven wheel 681, and connecting them through a drive belt, multi-level linkage is achieved, ensuring that the drive wheel 5 operates synchronously, reducing the risk of slippage or deviation, and enhancing stability during high-speed operation.
