Clearance adjustable deashing device for building construction

Abstract

The invention relates to the field of building equipment, in particular to a clearance adjustable deashing device for building construction. The clearance adjustable deashing device for building construction comprises a horizontally arranged movable mounting plate, wherein traction rings are horizontally arranged at two ends of the movable mounting plate, supporting mounting columns are verticallyarranged at four corners of the lower end of the movable mounting plate, lifting mounting plates horizontally are arranged right below the supporting mounting columns, limiting rotating racks are vertically arranged in the middle positions of the lifting mounting plates downward, and movable guide wheels are arranged at the lower ends of the limiting rotating racks through a rotating shaft. As aturning moving structure is matched with a limiting guiding shock absorbing structure, the device has good moving performance and shock absorbing performance. Active guidance and spiral pressurized guidance are achieved by means of active drive fit, so that follow-up aeration and dedusting is guaranteed. A ground clearance is adjusted stably by means of pneumatic synchronous lifting adjustment, sothat the dedusting efficiency and quality can be improved, various dedusting demands can be further met, and the practicality is improved obviously.

Description

technical field [0001] The invention relates to the field of construction equipment, in particular to an adjustable-gap ash cleaning device for construction. Background technique [0002] During construction, there is a lot of dust on the ground at the construction site, and it is very easy to cause secondary dust during secondary construction or decoration indoors, which will harm the health of construction workers and pollute the environment. In order to avoid secondary dust , the ground needs to be cleaned before construction, and a dust collection device is required. The existing dust collection devices use the airflow generated by negative pressure to inhale and filter the dust on the ground. Due to the high roughness of the building construction ground , the dust is not easy to be sucked up, and the building construction ground also contains dust with a relatively high quality. The airflow generated by the negative pressure alone cannot complete the dust cleaning. The...

[0002] During construction, there is a lot of dust on the ground at the construction site, and it is very easy to cause secondary dust during secondary construction or decoration indoors, which will harm the health of construction workers and pollute the environment. In order to avoid secondary dust , the ground needs to be cleaned before construction, and a dust collection device is required. The existing dust collection devices use the airflow generated by negative pressure to inhale and filter the dust on the ground. Due to the high roughness of the building construction ground , the dust is not easy to be sucked up, and the building construction ground also contains dust with a relatively high quality. The airflow generated by the negative pressure alone cannot complete the dust cleaning. There is secondary dust

[0003] Chinese patent (Notice No. CN209550073U) discloses a dust suction device for building construction. The rotation direction of the two brush rollers is opposite and the rotation direction of the lower side of the two brush rollers is opposite. The dust suction cover is located between the two brush rollers. There is an opening, and the dust suction port of the vacuum cleaner is connected with the opening, which can completely lift up the dust on the ground and filter it. Although the above problems can be improved, there are still many problems in terms of stable movement, pressurization and diversion, and synchronous lifting and adjusting clearance. Both have defects, which significantly improve the quality and efficiency of dust removal
