Flexible screw claw tool, visual guidance covering device and covering method

Abstract

The invention discloses a flexible screw claw tool, a visual guidance covering device and a covering method, wherein the flexible screw claw tool comprises a flexible screw claw which comprises a rotating body, a spring seat, a spring, a compressing seat and a screw claw; when a barrel mouth surface is not parallel to the surface of the screw claw, the lower end of the rotating body is a spherical surface, the compressing seat is connected with the rotating body by the elastic force of the spring, so that the spring is compressed upwards by the compressing seat under the action of the pressure of a barrel cover and a barrel mouth, the compressing seat forms a certain angle together with the barrel surface so as to enable the barrel cover to be parallel to the barrel mouth, and the barrel cover is firmly pressed on the barrel mouth by the compressing seat under the action of the spring. Furthermore, when the rotating body is driven to rotate by a pneumatic motor, an angle is formed by the rotating body and the barrel cover all the time, so that the barrel cover is screwed into the barrel mouth, and the cover can be closed when the barrel mouth is not flat. After the flexible screw claw tool, the visual guidance covering device and the covering method are adopted, the cover is automatically covered under the condition that the barrel surface is not flat, so that the intelligence of a covering machine and the efficiency of covering work are improved, and the personal safety of workers can be guaranteed.

Description

technical field [0001] The invention is suitable for a cover closing device of a liquid standard 200L material barrel. In particular, it involves the automatic lid closing device for the standard 200L material barrels of highly corrosive and highly toxic materials in the chemical industry. Background technique [0002] The cover closing device widely used at present is manual closing cover. The manual cover closing device adopts a commercially available cover closing wrench (a simple and simple cover closing wrench can also be made). Simply relying on manpower to close the lid, the degree of automation of the above methods is not strong, and it is completely dependent on manual labor to find the mouth of the barrel, which will cause certain harm to the human body in a highly toxic and highly corrosive environment. However, the manual closing of the lid is highly adaptable, and the lid closing work can still be completed smoothly even when the barrel surface is uneven. How...

Problems solved by technology

Only relying on manpower to close the lid, the degree of automation of the above methods is not strong, relying entirely on manual labor to find the mouth of the barrel, which will cause certain harm to the human body in a highly toxic and corrosive environment

However, the manual closing of the lid is highly adaptable, and the lid closing work can still be completed smoothly even when the surface of the barrel is uneven.

However, the existing mechanical lid closing device has low efficiency and low degree of automation, and it is difficult to complete the lid closing work when the barrel surface is uneven.

Therefore, it is a top priority to solve the problem that the mechanical lid closing device cannot accurately complete the lid closing work when the barrel surface is uneven
