Embodiment 1

[0049] The embodiment of the present application discloses an electric dust-proof net covering device.

[0050] refer to figure 1 , the electric dust-proof net covering device includes a first support frame 1 and a second support frame 2 arranged laterally opposite to each other, a dust-proof net 3 located between the first support frame 1 and the second support frame 2, and a dust-proof net for controlling the dust-proof net 3 Unwinding or winding unwinding mechanism 4.

[0051] refer to figure 1 , figure 2 The unwinding mechanism 4 includes a rewinding shaft 41 pivotally supported at the top of the first support frame 1 , a support shaft 42 pivotally balanced at the top of the second support frame 2 , and a drive assembly 43 for driving the take-up shaft 41 to rotate. The winding shaft 41 and the supporting shaft 42 are horizontally opposite and parallel to each other.

[0052] Two ends of the take-up shaft 41 are respectively provided with vertically arranged support b...

Embodiment 2

[0062] The embodiment of the present application discloses an electric dust-proof net covering device.

[0063] refer to Figure 4 The difference between the second embodiment and the first embodiment is that two sliding rails 6 located on the same horizontal height and parallel to each other are also arranged between the first support frame 1 and the second support frame 2 . The dust filter 3 is located between the two slide rails 6 . A plurality of supporting uprights 7 are arranged at the bottom end of the sliding rail 6 along the length direction of the sliding rail 6 at intervals, and the top ends of the supporting uprights 7 abut against the sliding rail 6 and are fixed together.

[0064] The side of the slide rail 6 facing the dustproof net 3 is provided with a guide groove 61 along the length direction of the slide rail 6 , and the guide grooves 61 on the two slide rails 6 are horizontally opposite to each other.

[0065] refer to Figure 4 , Figure 5 A plurality ...

Abstract

The application relates to an electric dust-proof net covering device, which belongs to the field of engineering construction, comprising a first support frame and a second support frame arranged laterally opposite to each other, a dust-proof net and an unwinding mechanism; the unwinding mechanism includes a winding shaft, a supporting shaft and a A drive assembly used to drive the rewinding shaft to rotate; the rewinding shaft and the supporting shaft are parallel to each other; one end of the dust-proof net is connected to the winding shaft, the other end of the dust-proof net is provided with a moving shaft, and both the supporting shaft and the winding shaft are provided with The transmission gear, the transmission gear on the support shaft and the transmission gear of the rewinding shaft are connected by a chain; the moving shaft is connected with the chain; when the driving component drives the rewinding shaft to lay out the dust net, the chain drives the moving shaft away from the reeling shaft. ; When the drive assembly drives the rewinding shaft to rewind the dust-proof net, the chain drives the moving shaft to approach the reeling shaft. The present application has the effect of reducing the fugitive dust flying into the air during the construction of the foundation pit.

Description

technical field [0001] The present application relates to the field of engineering construction, in particular to an electric dust-proof net covering device. Background technique [0002] In the construction of geotechnical projects, in order to reduce the dust on the construction site, it is necessary to cover all the exposed earthwork with dustproof nets, so as to reduce the fugitive dust generated by the exposed earthwork under the action of blowing air. [0003] During the construction of the foundation pit, the dust net needs to be lifted before the earthwork can be constructed, and a large amount of dust will still be generated during the construction, so that the dust will fly into the air and cause air pollution. pollution. SUMMARY OF THE INVENTION [0004] In order to reduce the dust flying into the air during the construction of the foundation pit, the present application provides an electric dust-proof net covering device. [0005] A kind of electric dust-proo...
