Description

Technical Field

[0001] The utility model relates to the technical field of supervision information devices, and more specifically, to a rotatable engineering supervision information device used on a tower crane. Background Art

[0002] A tower crane, also known as a tower crane, is a fully rotating crane with a vertical tower body. Its lifting arm is installed on the top of the tower body, forming a "Г"-shaped working space. During the engineering supervision process, in order to effectively monitor the operation of the tower crane, cameras and other monitoring information devices are usually installed.

[0003] Existing surveillance equipment has certain limitations. For example, Chinese patent application CN207179091U discloses a 360-degree rotating surveillance camera for smart buildings. The device uses a micro-motor to drive the rotating seat, which cooperates with the driving wheel, driven wheel and bevel gear set to achieve horizontal and vertical rotation of the camera, thereby expanding the camera range.

[0004] However, this type of monitoring information device that only supports horizontal and vertical rotation adjustment is difficult to adapt to the complex operating environment of the tower crane. Due to the long length of the tower crane's boom and the wide operating range, the existing device lacks the functions of forward and backward movement and height adjustment, and it is very easy to form a monitoring blind spot in a specific area of ​​the boom. It makes it difficult to fully capture the key details of the tower crane lifting process, and cannot meet the actual needs of engineering supervision for refined and no-dead-angle supervision of tower crane operations.

[0005] To this end, the present application proposes a rotatable engineering supervision and management information device for a tower crane, aiming to solve the above-mentioned problems. Utility Model Content
