Description

Intelligence welder helmet

Technical Field

The invention relates to a helmet, in particular to an intelligent welder helmet.

Background

The welding technology is mainly applied to metal base metal, and commonly used welding technologies comprise arc welding, argon arc welding, carbon dioxide arc welding, oxygen-acetylene welding, laser welding, electroslag pressure welding and the like, and plastics and other non-metal materials can also be welded. The metal welding methods are more than 40, and mainly include fusion welding, pressure welding and brazing. And the welder is at the welding process, because of the central temperature of welding arc column is up to 6000 ~ 8000 ℃, welding rod, weldment and coating are under the high temperature effect of electric arc, take place evaporation, condensation and gas, produce a large amount of smoke and dust and harmful gas to the human body directly receives arc light radiation during the welding, if the welding operation in this time, will make the welder take place multiple occupational disease.

When carrying out the welding operation at present, the welder is wear-type welding helmet mostly, or the hand-held type welding helmet, and the optical filter that sets up on these helmets has already been fixed, and the colour is dark, inconvenient observation to the welding position situation, so when using wear-type welding helmet to carry out welding operation, need frequently to go up and down to weld helmet and observe welding work, just so have complex operation, the shortcoming that work efficiency is lower, if use the welding helmet of the adoption liquid crystal technology that current intelligent degree is high, it adjusts the intensity of welder's visible light through the photodetection technique, but this kind of face guard is with high costs, difficult popularization, if use hand-held type welding helmet, can only carry out one-hand work during welding operation, there is very big inconvenience and danger.

In view of this, can not satisfy present work demand, so need to develop a welder's intelligent face guard urgently, make it can observe the welding situation under the condition of not taking off the face guard, protect the welder's face when welding, in order to improve work efficiency and increase welding operation security, and can avoid welder to breathe smoke and dust and harmful gas under the closed environment, the service environment of extension welder's face guard, further messenger welder can obtain the health guarantee when carrying out welding operation, and this welder's intelligent face guard is with low costs easy popularization, and easy operation, can not influence welder's welding operation in the use.

Disclosure of Invention

In order to overcome the defects that the existing helmet for welders only can work with one hand and is complex in operation and difficult to observe the welding seam, the invention has the technical problems that: the intelligent welder helmet can observe the welding condition without detaching the mask and can perform double-hand welding work.

An intelligent welder helmet comprises a mounting frame, detachable elastic fastener belts, an integrated top belt, a motor, rotary blocks, filter lenses, limiting blocks, connecting frames, a triggering device moving through active parts of human heads and a power supply device supplying power to the helmet, wherein the mounting frame comprises a front group and a rear group; when the helmet is used, the helmet is worn on the head, the removable elastic buckle belt and the integrated top belt are used for fixing, the filter lens blocks the eyes, the limit block at the lower side drags the filter lens, welding operation can be carried out at the moment, if the active part of the head contacts the trigger device at the moment, the trigger device controls the motor to rotate clockwise through the power supply device, the motor drives the rotating block and the filter lens to rotate clockwise, the upper limit block blocks the filter lens at the moment, the filter lens does not block the eyes any more at the moment, the condition of welding operation can be observed at the moment, if the active part of the head is separated from the contact with the trigger device, the power supply device disconnects the power supply of the motor, the filter lens rotates anticlockwise, and the lower limit block drags the filter lens, the filter lens will then re-block the eye.
