Description

Technical Field

[0001] The utility model relates to the technical field of safety engineering, and in particular to a longitudinal guide beam safety belt suspension device. Background Art

[0002] During the box girder erection or equipment maintenance process of a bridge crane, personnel need to walk through the passage at the longitudinal guide beam. At this time, because there is no standardized edge protection on both sides of the longitudinal guide beam and the operation is at high altitude, there is nowhere to hang the safety belt, or the hanging point is fixed. The safety belt needs to be reset and hung again for each movement, and the safety of the operators is not guaranteed. Utility Model Content

[0003] In view of the defects existing in the prior art, the utility model provides a movable safety device for hanging safety belts at the longitudinal guide beam of a bridge crane. The main technical problem that can be solved is the problem that the fixed end cannot move with the operator when the operator hangs the safety belt during the erection of the box beam or equipment maintenance of the bridge crane.

[0004] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0005] A longitudinal guide beam safety belt hanging device comprises an I-beam installed on the longitudinal guide beam; the I-beam is installed along the length direction of the longitudinal guide beam, and a sliding mechanism is arranged on the I-beam; the sliding mechanism can slide on the lower wing plate of the I-beam along the length direction of the I-beam, and a steel plate is arranged below the sliding mechanism, and a hanging hole for hanging the safety belt is arranged on the steel plate.

[0006] The utility model provides a longitudinal guide beam safety belt suspension device, which realizes the flexible suspension of the safety belt by arranging a sliding mechanism that can slide along the length direction of the I-beam on the I-beam and a steel plate with a suspension hole below it. Such a design allows the safety belt to be adjusted according to the specific needs of the working area, thereby improving the safety and flexibility of the workers when working at high altitudes.

[0007] Preferably, the sliding mechanism comprises a suspension box in a U-shaped plate shape with an opening facing upward, and mounting holes are provided on two oppositely disposed side walls of the suspension box, and bearings capable of rolling on the lower wing plate of the I-beam are installed at the mounting holes.

[0008] Preferably, at least two mounting holes are provided on the two opposite side walls of the suspension box, and a bearing is installed at each mounting hole. The bearing is arranged between the I-beam waist plate and the side arm of the suspension box. A steel rod is fixed in the mounting hole, and the bearing is installed on the steel rod.

[0009] In the utility model, the use of the bearing reduces the sliding resistance, ensures the stability and durability of the sliding mechanism, and thus enhances the practicality and reliability of the entire suspension system.

[0010] Preferably, limit plates are provided at both ends of the lower wing plate of the I-beam, and the bearing is arranged between the waist plate of the I-beam and the limit plates to ensure stable operation of the sliding mechanism.

[0011] Through the utility model, the use of steel rods as connecting materials can ensure that the connecting part has high strength and good load-bearing capacity. This is essential to ensure the safety of operators when using it. By welding and fixing in the reserved circular hole, the connection stability between the sliding end and the safety belt suspension device can be increased. Good welding can prevent loosening or breaking under repeated loads or accidental impacts; the sliding end designed for the safety belt suspension device provides a solid fixing point, which is a basic guarantee for the life safety of operators, especially when working at height.
