Description

Technical Field

[0001] The utility model relates to the technical field of tower crane hooks, in particular to a device for visual monitoring of the tower crane hook. Background Art

[0002] Tower cranes are also called tower cranes, which are widely used in the vertical and horizontal transportation of materials and the installation of building components in house construction. Tower cranes need to be used with hooks, which are a common type of lifting equipment in lifting machinery. As the tower crane has a large operating space, the operator in the operating room is in the visual blind spot, which can easily cause accidents due to the inability to see the surrounding conditions of the tower crane.

[0003] In the related art, before using the hook, it is necessary to check the appearance and structure of the hook. When selecting the hook, it is necessary to consider factors such as the weight, shape and size of the object to be hoisted. Selecting a hook that can match the object to be hoisted can avoid problems such as uneven force on the hook in actual operation. The hook is fixed on the hook frame on the tower crane arm. After the hook is fixed, the object is hoisted up. After moving to a certain position, the object is put down to facilitate the use of the hook. However, due to the long-term use of the hook, the operator sits inside the tower crane to operate the hook normally, and the tower crane is far away from the hook, which makes it impossible for the operator to observe the wear of the hook, which may cause the hook to be damaged during use, making it inconvenient to use. In view of this, we have introduced a device for visual monitoring of the hook of a tower crane. Utility Model Content
