Dust-proof net lifting mechanism suitable for building foundation pit

Abstract

The invention discloses a dust-proof net lifting mechanism suitable for a building foundation pit. The dust-proof net lifting mechanism comprises a dust-proof system, a force measuring system and a traction system; the dust-proof system comprises a steel wire rope and a dust-proof net, and the dust-proof net is detachably installed on the steel wire rope to cover the foundation pit; the force measuring system comprises a wireless dynamometer and a wireless receiver, the wireless dynamometer is in communication connection with the wireless receiver, and the wireless dynamometer is connected with the steel wire rope; the lifting system comprises a stand column, a traction rope and a traction device; the stand column is arranged on one side of the foundation pit and vertically arranged, the traction device is installed on the stand column, one end of the traction rope is a free end, the free end is connected with the wireless dynamometer, and the other end of the traction rope is connected with the traction device; and the traction device works to recover or release the traction rope, when the traction rope is recovered, the free end moves upwards, the dust-proof net ascends, and whenthe traction rope is released, the free end moves downwards, and the dust-proof net descends. The mechanism can realize lifting of the dust-proof net and can monitor the tension of the steel wire rope.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a dust-proof net lifting mechanism suitable for building foundation pits. Background technique [0002] At present, the country is paying close attention to environmental governance. Dust control in the construction process of the construction industry is an important work content of the national environmental governance. The dust during construction mainly comes from the soil exposed during the excavation of the foundation pit. In order to control the dust, the traditional method is to cover the surface of the soil with geotextile or dense mesh. Pulling the wire rope above the foundation pit, and fixing the dust-proof net on the wire rope, building a dust-proof and noise-reducing shed in this way is a new type of dust-proof and noise-reducing measure for the foundation pit. In the prior art, the wire ropes used in the dust-proof and noise-reducing sheds of foundation pits a...

Problems solved by technology

This shortcoming makes it difficult to fix, repair and replace the wire rope, and it is difficult to realize repeated use

Moreover, in rainy and snowy weather, the load on the dust-proof net increases sharply, and the force on the wire rope hanging on the net increases sharply. If no measures are taken, the wire rope may break and endanger the safety of personnel in the foundation pit.
