Embodiment Construction

[0018] Such as Figure 1 to Figure 3 As shown, the movable hanging operation platform for the welding of the steel box girder bridge guardrail includes a hanging operation platform 1 and a counterweight trolley 2. Through the welding connection, the hanging operation platform 1 needs to be hung on the steel guardrail 21 before the steel guardrail 21 is welded, and the counterweight trolley 2 is set on the surface of the bridge (steel box girder) beam body 23, and the counterweight is pushed by the steel tie rod 16. The car 2 is connected with the hanging operation platform 1, which plays the role of counterweight, so that the force of the hanging operation platform 1 acting on the steel guardrail 21 can be balanced inside and outside, so as to prevent the steel guardrail 21 from being subjected to excessive external pulling force generated by the hanging operating platform 1 and a fall occurs. The counterweight trolley 2 can be promoted on the bridge (steel box girder) beam b...

Abstract

The invention provides a movable hanging operation platform for welding a steel box girder bridge guardrail, the steel guardrail needing to be welded is placed on a steel box girder or a bridge body, the movable hanging operation platform comprises a hanging operation platform and a counterweight cart, and the counterweight cart is located on the surface of the steel box girder or the bridge body; the hanging operation platform comprises a steel support and rolling wheels, and the steel support is designed to be in an inverted U-shaped groove shape to be clamped on the steel guardrail and rolls on the steel guardrail through the rolling wheels in the U-shaped groove. And the counterweight cart is connected with the hanging operation platform through a steel pull rod. The steel guardrail welding device can meet the requirement of moving to any section on a long steel guardrail for steel guardrail welding operation. The hanging operation platform is simple in structure, low in manufacturing cost and convenient to operate, and the safety of constructors operating in the hanging operation platform can be ensured. The device is very suitable for welding steel guardrails on two sides of a steel box girder structure bridge.

Description

technical field [0001] The invention relates to an operation platform, in particular to a movable hanging operation platform for steel box girder bridge guardrail welding. Background technique [0002] During the construction of steel box girder structure bridges, it is usually necessary to install guardrails on both sides of the road on the girder box girder bridge deck. The guardrails are generally steel guardrails and are installed on the steel box girder by welding, because the steel guardrails are located at the edge of the steel box girder The welding seam between the outer side of the steel guardrail and the steel box girder is a high-altitude edge operation, and an outer aerial work platform needs to be provided. The conventional method is to set up scaffolding at the lower part of the bridge from the ground to the steel guardrail as an operating platform or use a special For lifting operation platform equipment, the cost of the above methods is relatively high.
