Camera displacement changing device for bridge crane

Abstract

The invention discloses a camera displacement changing device for a bridge crane, which is suitable for being installed on both sides of the crane's hook and suspended under the steel structure of the main girder of the crane, wherein the camera displacement changing device includes: A camera assembly, which includes two cameras; a telescopic device assembly for vertically lifting the camera assembly, which includes two telescopic devices, each telescopic device includes a telescopic rod and a fixed jacket, and the lower ends of each telescopic rod are connected to corresponding The camera can move vertically together with the corresponding camera; the sealing assembly that can be opened and closed includes two sealing devices, and each sealing device includes a protective cover, an openable bottom plate, and a lifting assembly hinged to the bottom plate. The present invention can meet the angle of view requirements of intelligent or unmanned cranes for video monitoring by adding camera displacement changing devices on both sides of the crane, and also has the function of dustproof and rainproof, which can meet the harsh working conditions of open air and dusty environment use below.

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...
