Camera displacement changing devices for bridge crane

Abstract

The invention discloses camera displacement changing devices for a bridge crane. The devices are suitable for being arranged on the two sides of a lifting hook of the crane and suspended below a mainbeam steel structure of the crane; the camera displacement changing devices comprise camera assemblies, telescopic device assemblies and sealing assemblies; the camera assemblies comprises cameras; the telescopic device assemblies are used for lifting the camera assemblies in the vertical direction and comprise telescopic devices, the telescopic devices comprise telescopic rods and fixed outer sleeves, and the lower ends of the telescopic rods are all connected to the corresponding cameras so as to move together with the corresponding cameras in the vertical direction; and the sealing assemblies can be opened and closed and comprises sealing devices, and the sealing devices comprise protective outer covers, bottom plates capable of being opened and lifting assemblies hinged to the bottom plates. According to the technical scheme, the camera displacement changing devices are additionally arranged on the two sides of the crane, so that the visual angle requirement of intelligent or unmanned video monitoring of the crane is met; and the dustproof and rainproof functions are achieved so that the devices can be used in the open air and in the severe working condition environment with large dust.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a camera displacement changing device for bridge cranes. Background technique [0002] With the development of intelligent and unmanned bridge cranes, the demand for image monitoring and image recognition technology during crane operation and hoisting is also increasing. However, the bridge crane is generally located in the upper part of the workshop, and the heavy objects to be lifted are below its running path. In order to monitor the heavy objects to be lifted, it also meets the image requirements of some special cranes, such as casting cranes for molten iron The decoupling recognition of bales, the decoupling recognition of steel coils by clamp cranes, etc., are traditionally used to install cameras on cranes, but this is often difficult to meet the viewing angle, especially the viewing angle requirements of image recognition technology. [0003] Therefore, there is a need in...
