A plate unit non-destructive turn over spreader and turn over method

Abstract

The invention relates to a plate unit non-destructive turning spreader and turning over which can fundamentally solve the damage to the steel by the fixture in the process of turning over the steel structure plate unit, avoid the safety and quality risks of the current way of turning over, and realize the safe and non-destructive turning of the steel structure plate unit method, a ladder-shaped placement plate unit bracket is formed between the main beam of the lifting bracket and the main beam of the bracket by a plurality of bracket cross braces, and one bracket main beam in the ladder-shaped placement plate unit bracket is rotated through multiple The support and the bottom beam are hinged to form a ladder-shaped display plate unit rotating bracket. Advantages: First, it avoids the safety and quality hazards of the plate unit falling due to the loosening of the teeth of the fixture, so that it can be turned over safely and steadily; The processing quality of the plate unit is guaranteed, and the turning over without damage is achieved; the third is that by adjusting the position of the spreader pallet, the plate unit of different specifications can be rotated and turned over, and the scope of application is wider.

Description

technical field [0001] The invention relates to a panel unit non-destructive turning spreader and turning over which can fundamentally solve the damage to the steel by the fixture during the turning process of the steel structure plate unit, avoid the safety and quality risk of the current turning method, and realize the safe and non-destructive turning of the steel structure plate unit The method belongs to the field of manufacture of plate unit overturning spreaders. Background technique [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, ...

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 / CR 9211-2015 stipulates: "When the depth is 0.3mm ~ 1mm, it can be smoothed, and when the depth exceeds 1mm, it should be smoothed after repair welding"; in addition, in the actual application process, Due to the strain of the fixture, improper operation of the operator, etc., it is easy to cause the plate unit to 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
