Plate unit non-destructive turnover hanger and turnover method

Abstract

The invention relates to a plate unit non-destructive turnover hanger and a plate unit non-destructive turnover method, which can radically solve damages of a clamp to steel in a turnover process of a steel structure plate unit, can avoid safety and quality risks of a current turnover mode, and can realize safe non-destructive turnover of the steel structure plate unit. An trapezoidal plate unit placing bracket which consists of a plurality of bracket cross arms is arranged between a lifting bracket main beam and a bracket main beam; and one bracket main beam in the trapezoidal plate unit placing bracket is hinged with a bottom beam through a plurality of rotary supporting bases to form a trapezoidal plate unit placing rotary bracket. The plate unit non-destructive turnover hanger has the advantages that: firstly, safety and quality hidden danger, due to the fact that occlusive teeth are loosened and are even dropped, of the plate unit is avoided, so that safe and stable turnover is achieved; secondly, various damages such as tooth marks, collision, scratches and the like, generated in the turnover process, of the plate unit are eliminated, so that the plate unit processing quality is guaranteed, and non-destructive turnover is achieved; and thirdly, by regulating the position of a hanger supporting plate, rotary turnover of plate units of different specifications is met, and therefore, the scope of application is wide.

Description

Technical field [0001] The invention relates to a plate unit non-destructive turn-over sling and turn-over which can fundamentally solve the damage to the steel by the clamp during the turn-over process of the steel structure plate unit, avoid the safety and quality risk of the current turn-over method, and realize the safe and non-destructive turn-over of the steel structure plate unit The method belongs to the manufacturing field of a plate unit turning sling. Background technique [0002] In the field of steel structure manufacturing, the common method for turning over the plate unit is to fix the clamp on one side. The lifting equipment is first lifted and hoisted until it is vertical to the ground, and the walking mechanism is moved to cooperate to roll over to the ground. Although the operation method is simple and easy, it is convenient Implementation, but the plate unit that is turned over by this method will produce tooth marks of varying depths at the fixtures, and the ...

AI Technical Summary

Problems solved by technology

[0002] In the field of steel structure manufacturing, the general method of turning over the plate unit is to fix the fixture on one side, lift the lifting equipment to lift it to be perpendicular to the ground, and then walk the walking mechanism to cooperate with turning over to the ground. Although this operation method is simple and easy, it is convenient implementation, but the plate unit turned over by this method will produce tooth marks of different depths at the clamping place, and the current steel structure manufacturing standards and specifications have clear requirements for steel processing defects, such as "Manufacturing Specifications for Railway Steel Bridges "Q / CR9211-2015 stipulates: "When the depth is 0.3mm ~ 1mm, it can be ground evenly, and when the depth exceeds 1mm, it should be smoothed after repair welding"; in addition, in the actual application process, due to Fatigue of the fixture, improper operation of the operator and other reasons may easily lead to the phenomenon that the plate unit will fall and be damaged due to the loosening of the teeth of the fixture

It can be seen that the current method not only seriously affects the appearance quality of the panel unit, but also increases additional repair costs, reduces production efficiency, and hides hidden dangers to safety and quality
