Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

In the prior art, because the inner side structure of the bridge type traveling crane girder is not used much, people often pay attention to the safety factor inadequately and potential safety hazards in the production process are easy to occur.

Example 1

As shown in attached figures 1 and 2, the safety protection device for the bridge type traveling crane girder comprises a traveling crane girder end beam 1, a steel wire rope 2, a trolley 3, a trolley supporting point support 4, an end support 5 and a steel wire rope threading hole 6; the trolley supporting point supports 4 are arranged at two ends of the trolley 3, and the steel wire rope 2 penetrates through a steel wire rope threading hole 6 on the trolley supporting point supports 4; the steel wire rope 2 is fixedly connected with the end bracket 5 at two sides of a girder at the inner side of the driving; the end bracket 5 is arranged on the end beam 1 of the girder of the traveling crane; the trolley 3 is arranged on the inner side of the girder of the traveling crane.
