[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 4 The utility model provides a technical solution: a visual monitoring device for tank truck loading and unloading, including a base 1, a vertical pole 2 is vertically fixed to the upper end surface of the base 1; a movable frame 4 that can move up and down is provided on the vertical pole 2, a camera 5 is installed on the movable frame 4, the movable frame 4 is connected to one end of a steel wire rope 6, the other end of the steel wire rope 6 is connected to a take-up roller 7, the take-up roller 7 is connected to the vertical pole 2 by a bearing, a rocker 8 is fixed to the right end surface of the take-up roller 7, a fixing plate 9 fixed to the vertical pole 2 is provided on the upper left of the take-up roller 7, and the fixing plate 9 is connected to a limit rod 10.

[0024] A limit block 201 is welded and fixed on the side of the vertical pole 2, and the limit block 201 contacts the movable frame 4 to achieve positioning; a rotatable guide wheel 3 is also connected to the upper end of the vertical pole 2 by a bearing, and the guide wheel 3 contacts the wire rope 6; balls 401 are evenly installed on the movable frame 4, and the balls 401 contact the vertical pole 2 to roll; a baffle 701 is also fixed on the take-up roller 7, and a limit hole 702 is provided at an equal angle on the outer side of the baffle 701; the limit rod 10 is slidably connected to the fixed plate 9, and the limit rod 10 is snap-fitted to the limit hole 702;

[0025] When using the visual monitoring device for tanker loading and unloading, if Figure 1-Figure 4 As shown, firstly, the whole device can be installed and fixed by means of expansion screws in cooperation with the circular holes on the base 1. After the installation is completed, the limiting rod 10 can be pulled to slide, so that the limiting rod 10 can be separated from the limiting hole 702, thereby releasing the limiting effect on the take-up roller 7. Then, the take-up roller 7 can be driven to rotate by turning the rocker 8, so that the take-up and release of the wire rope 6 can be realized. In addition, the guide effect of the guide wheel 3 can be used to prevent the wire rope 6 from getting stuck, thereby ensuring the normal take-up and release of the wire rope 6. When the wire rope 6 is taken up, the movable frame 4 is restrained. The pulling force of the steel wire rope 6 moves upward, and the rolling effect between the ball 401 and the vertical pole 2 can effectively reduce the friction force, ensure the normal movement of the movable frame 4, and thus realize the height adjustment of the movable frame 4 and the camera 5, so as to meet the installation requirements of the camera 5 at different heights, and when the movable frame 4 contacts the limit block 201, the limit can be realized to avoid the installation height of the movable frame 4 being too high, and according to the above principle, when the take-up roller 7 is rotated in the reverse direction to realize the release of the steel wire rope 6, the camera 5 can be moved down for later maintenance;

[0026] A disc 1001 is also fixed on the limiting rod 10, and one end of a spring 1002 is fixed on the disc 1001, and the other end of the spring 1002 is fixed on the fixing plate 9;

[0027] When the limiting rod 10 is pulled away from the limiting hole 702, as shown in FIG. Figure 1-Figure 4 As shown, at this time, the spring 1002 is forced to shrink, which facilitates the height adjustment of the camera 5. After the height adjustment of the camera 5 is completed, by loosening the limit rod 10, under the elastic action of the spring 1002, the limit rod 10 can be reset and nested with the limit hole 702, thereby realizing the limiting effect and ensuring the stability of the device. After the camera 5 is installed, the camera 5 can be used to shoot the tank truck loading and unloading video and transmit it to the control background for real-time monitoring. This is the working principle of the visual monitoring device for tank truck loading and unloading.
