A worm 7 is arranged between the front and rear inner walls of the control box 3. The worm 7 is meshed with the worm wheel 6, wherein the helix lead angle of the worm 7 is less than the equivalent friction angle between the meshing teeth of the worm 7 and the worm wheel 6. The worm wheel 6 and the worm 7 are adopted to have a self-locking function. In any case, during the mobile shooting process, the track frame 2 is moved by external force. One end of the worm 7 is rotatably connected to the inside of the control box 3, and the other end of the worm 7 is fixedly connected to a drive motor 8, wherein the drive motor 8 can be adopted in the control box 3. A storage battery is added inside or it is directly connected to the power supply required in the process of video recording, and the driving motor 8 can be controlled by wireless remote control or wired control. A tooth groove 9 is opened in the center section of the top of the track frame 2, and one end of the bottom of the gear 5 passes through the control box 3 and meshes with the tooth groove 9. The top of the track frame 2 is provided with a first positioning groove 10 on both sides of the tooth groove 9, and a first positioning block 11 is slidably connected inside the first positioning groove 10. A second positioning groove 12 is opened on the top of a section of the track frame 2 near both ends, and a second positioning block 13 is slidably connected inside the second positioning groove 12.

Therefore, when the shooting length needs to be increased, there is no need to increase the length of the track frame 2 itself, so that the track frame 2 correspondingly increases the cameraable length, thereby eliminating the need to replace a longer truss 1, reducing the floor space occupied during shooting, and reducing the load-bearing capacity of the truss 1. In addition, during the fixing process, only the first pipe clamp 14 and the two second pipe clamps 15 need to be fixed to the longitudinal beam 102, so that it can be installed quickly.

[0032] Furthermore, in the above technical method, the tooth groove 9 and the second positioning groove 12 are both arranged on the transverse center line of the track frame 2, and the two second positioning grooves 12 are symmetrically arranged about the tooth groove 9, so that the track frame 2 is evenly stressed.

[0033] Working principle of the present invention:

[0034] Refer to the instruction manual Figure 1-5When a track frame 2 and a truss 1 are installed, the first pipe clamp 14 and the second pipe clamp 15 at the top of the control box 3 and the top of the second positioning block 13 of the track frame 2 are fixedly connected to the center position of the longitudinal beam 102 corresponding to the bottom of the truss 1, so that the forces on both sides of the truss 1 are evenly applied, and it is prevented that one side of the truss 1 is subjected to more forces and deflected when installing a track frame 2. When the length to be photographed is greater than the length of the track frame 2, the drive motor 8 is started, and the shaft of the drive motor 8 rotates counterclockwise, so that the worm 7 drives the worm wheel 6 to rotate counterclockwise, so that the center shaft 4 drives the gear 5 to rotate counterclockwise, so that the gear 5 pushes the track frame 2 to move in the opposite direction, changing the initial position of the starting end of the track frame 2. When the gear 5 moves to one end of the tooth groove 9 or the second positioning block 13 moves to one end of the second positioning groove 12, the drive motor 8 is stopped, thereby increasing the original length of the track frame 2. The length between the previous position and the current position, when the camera completes shooting of a position, the drive motor 8 is started to rotate the shaft of the drive motor 8 clockwise, so that the worm 7 drives the worm wheel 6 to rotate clockwise, so that the central shaft 4 drives the gear 5 to rotate clockwise, so that the gear 5 pushes the track frame 2 to move in the opposite direction, and the initial position of the tail end of the track frame 2 is changed. When the gear 5 moves to the other end of the tooth groove 9 or the second positioning block 13 moves to the other end of the second positioning groove 12, the drive motor 8 is stopped, and the position of the tail end of the track frame 2 is effectively changed, so that compared with the original position of the track frame 2, the track frame 2 is correspondingly increased in camera length, so that there is no need to replace a longer truss 1, reducing the floor space occupied during shooting, reducing the load-bearing capacity of the truss 1, and in the fixing process, only the first pipe clamp 14 and the two second pipe clamps 15 need to be fixed to the longitudinal beam 102, so that it can be installed quickly;

[0035] Refer to the instruction manual Figure 5 When installing the two track frames 2 and the truss 1, loosen the locking nuts 22 on the connecting rods 21 of the first pipe clamp 14 and the second pipe clamp 15, rotate the lower clamp 1890 degrees, and make the first pipe clamp 14 and the second pipe clamp 15 perpendicular to the crossbeam 101, so as to be fixedly installed with the crossbeam 101, and effectively adjust the angles of the first pipe clamp 14 and the second pipe clamp 15 to make them suitable for fixing the crossbeam 101 and the longitudinal beam 102 of the truss 1, so as to ensure that the truss 1 is always in a uniform load-bearing state according to the number of installations, and prevent the truss 1 from being deflected and damaged.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
