Description

Light top suction cover

Technical Field

The utility model relates to the field of industrial dust removal and waste gas treatment, in particular to a light top suction cover.

Background

In the control and management of smoke and exhaust pollution in industrial manufacturing industry, smoke and exhaust generated by each manufacturing process are generally effectively captured, and then purified or treated. However, due to the limitations of the production process, it is very difficult to trap the exhaust gas generated by some production processes and conditions. For example, most vehicle frames and steel structures are welded under the working condition that the workpieces are assembled and disassembled by adopting a crane or a hoist above, welding smoke dust slowly rises due to hot smoke dust, and smoke dust and waste gas are captured by adopting a fixed-position top suction cover covering all welding points on the upper part of a welding workbench, so that a hoisting tool for assembling and disassembling the workpieces and the top suction cover interfere with each other, and the respective functions are difficult to realize simultaneously.

When welding large-sized workpieces, the workpieces need to be lifted by using a crane to enter and exit, and at the moment, the fixed top suction cover needs to be removed, so that the workpieces are inconvenient to enter and exit. In addition, the size of the welding work piece of the welding station is changed frequently according to the output requirement, and the size of the required capturing top suction cover is also changed according to the size of the work piece. In addition, due to the different equipment layout and process flows in the field workshop, the welding and polishing stations are changed, and the fixed top suction cover needs to be flexibly moved and changed, so that a series of technical problems can be generated. At present, some suction hoods are installed on a cantilever to rotate, but due to the field layout problem, the upright posts of the suction hoods are far away from a station, the installation angle is not fixed with the center of the suction hood, and the angle of the suction hood after rotation is not attractive and is not parallel to the station. In addition, the suction cover is required to be rotated by a certain angle when the suction cover is interfered with the posts around the site during frequent rotation.

The prior art CN110052468A discloses a cantilever type telescopic rotary suction hood, the suction hood is provided with a rotary mechanism on a rotary upright post, the rotary mechanism drives a cantilever which swings reciprocally around the central axis of the rotary upright post, a rotary mechanism arranged at one end of the cantilever far away from the rotary mechanism, the suction hood which drives to rotate through the rotary mechanism, and a telescopic hood which is horizontally and slidingly sleeved with the suction hood, an inner air duct is arranged in the cantilever, one end of the cantilever far away from the suction hood is provided with an air suction duct which is communicated with an external dust removal system, and the air suction duct, the inner air duct, the rotary mechanism and the suction hood are sequentially communicated, and the telescopic hood drives to slide through a telescopic cylinder. Although the suction hood can avoid lifting workpieces through the cantilever and the slewing mechanism, the slewing mechanism can be driven only by adding the air cylinder, the air cylinder assembly occupies part of space and increases the load of the cantilever, the suction hood can prevent lifting the workpieces during rotation and can possibly generate falling danger, and weight components such as the slewing mechanism, the suction hood, the telescopic air cylinder and the rotary air cylinder are simultaneously arranged on the cantilever, so that the burden of the cantilever is increased due to a complex structure.
