Description

Technical Field

[0001] The utility model relates to the technical field of video monitoring, in particular to an industrial heavy-load high-precision anti-shock pan. Background Art

[0002] During the operation of a gantry crane, the driver needs to observe the material grabbing and unloading process of the spreader in real time in the cab. However, since the cab is located in a position where the relevant situation of the spreader cannot be directly observed by the naked eye, a camera system is needed that can track the actual operating position of the spreader in real time and center the position of the spreader in the picture. In addition, since the gantry cranes and other large equipment at the port site will generate mechanical vibrations during operation, the camera system installed on them is required to have anti-vibration and anti-shock functions. Conventional camera products on the market are roughly divided into two types. One type cannot track the movement of the observed object in real time, and the other type is a spherical camera, which intelligently identifies the movement of the observed object based on the AI ​​algorithm and follows it. However, this type of recognition is mostly used for human or vehicle recognition. If it is used in the above application environment, a large amount of material training is required again, and the training results may not meet the requirements of high-precision tracking. On the other hand, the movement mechanism of this spherical camera system itself basically adopts belt transmission, and the shell is mostly made of aluminum alloy or plastic. If this type of equipment is used on the large lifting equipment of the above-mentioned port, it will cause damage to the camera system and have a short lifespan. If the damaged parts fall to some important parts of the large lifting equipment, it may also cause failure of the large lifting equipment. Therefore, there is an urgent need for a camera system that can automatically track the movement trajectory of the observed object and resist certain impact and vibration. The pan / tilt is the most important rotating component in the camera system, so an industrial heavy-duty high-precision impact-resistant pan / tilt came into being. Utility Model Content

[0003] The purpose of the utility model is to provide an industrial heavy-load high-precision impact-resistant pan / tilt head in response to the defects and shortcomings of the prior art, which solves the problem that during the grabbing and unloading operations of large mechanical equipment such as gantry cranes, conventional monitoring means cannot effectively position the spreader due to the low precision or low structural strength of the pan / tilt head, causing the spreader to shift in position on the monitoring screen and the inability to adjust the pan / tilt head angle in real time following the spreader; the spreader screen is always in the center of the monitoring screen, making it convenient for the driver to observe the operation of the spreader.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical solutions: it comprises an upper cover, an upper shell, an upper motor turntable, a pan-tilt control board, a lower spindle turntable, a lower shell, a lower motor turntable, a lower cover, an upper output spindle and an upper turntable bracket; the lower motor turntable is fixed in the lower shell, and the bottom cover of the lower shell is provided with a lower cover; the lower spindle turntable is fixed on the power output plane of the lower motor turntable, the upper turntable bracket is fixed on the lower spindle turntable, the upper motor turntable and the pan-tilt control board are both fixed on the left side of the upper turntable bracket, the upper shell is sleeved on the outer side of the lower spindle turntable, and the upper output spindle is fixed on the power output plane of the upper motor turntable after passing through the upper shell, and the top cover of the upper shell is provided with an upper cover; the pan-tilt control board is control-connected to the PLC control system; the motor driver in the upper motor turntable and the motor driver in the lower motor turntable are both electrically connected to the pan-tilt control board.

[0005] Preferably, an O-ring is used to seal between the upper cover and the upper shell.

[0006] Preferably, an O-ring is used to seal between the lower cover and the lower shell.

[0007] Preferably, a skeleton sealing ring is used to seal between the upper output spindle and the upper housing.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model provides an industrial heavy-load high-precision impact-resistant pan / tilt head, which solves the problem that during the grabbing and unloading operations of large mechanical equipment such as gantry cranes, conventional monitoring means cannot effectively position the sling due to the low precision or low structural strength of the pan / tilt head, causing the sling to be offset in the monitoring screen and unable to adjust the pan / tilt head angle in real time following the sling; the sling screen is always in the center of the monitoring screen, making it convenient for the driver to observe the operation of the sling.
