Summary of the invention
Technical problem to be solved in the utility model provides a kind of tunnel noise-proofing facility, tries hard to significantly reduce because the constructing tunnel noise that causes of environment to external world with a kind of simple and easy to do way.
Described tunnel noise-proofing facility, it is characterized in that: comprise the sound insulation curtain that is arranged on the outside, tunnel face, sound insulation curtain draw-gear, traction control plate and traction electric machine, described sound insulation curtain draw-gear comprises the driven pulley that is arranged at both sides, top outside the tunnel face, drive, and drive and the pull rope of loopy moving around described driven pulley and drive and by described drive, one end of described sound insulation curtain and top, tunnel face body of wall stay hook are fixed, the other end and described pull rope fixedly become drawing head, the top of sound insulation curtain is provided with a plurality of slip rings, and described slip ring movable set is on described pull rope; Described traction electric machine drives the forward and reverse rotation of described drive by reductor, so that described sound insulation curtain is driven folding sound insulation curtain by described drawing head, the start and stop of described traction electric machine and rotation direction are controlled by described traction control plate.
As a kind of embodiment, described sound insulation curtain is made of the sound insulation curtain of two width of cloth opposite openeds, the drawing head of described opposite opened sound insulation curtain is arranged at respectively the medial extremity of the top margin of two width of cloth sound insulation curtains, the stay hook of sound insulation curtain is arranged at respectively the outboard end of two width of cloth sound insulation curtain top margins, and the slip ring of two width of cloth sound insulation curtains is arranged at respectively on the overhanging cable and lower pull rope of described pull rope, so that two described sound insulation curtain whiles under the drive of traction electric machine are pulled open to both sides or close up to the centre.
As prioritization scheme, at the body of wall of described pull rope medium position the support pulley is housed, described pull rope places on the described support pulley, and the movable supporting that provides to described pull rope is provided.
Described traction control plate drives the starting switch of described traction electric machine by wired or wireless remote signal.
As embodiment, described sound insulation curtain is take canvas, cotton or sponge as main body, or leather layer is material in addition.To play preferably soundproof effect.As prioritization scheme, described sound insulation curtain is take the single or multiple lift canvas as material, and thickness is that 5mm is to 15mm.The soundproof effect of thicker sound insulation curtain is better, but can increase the weight of whole sound insulation curtain, strengthens the load of pull rope and traction electric machine.
The utility model realizes significantly reducing the noise of blasting of caused by tunnel construction by simple and effective mode, avoid the interference of personnel's noise outside the hole and guarantee that the advantage that reflects in safety of building, the especially Construction of City Tunnel is more outstanding.Draw-gear and sound insulation curtain simple in structure, be easy to safeguard and install, and easy to use, successful.
Description of drawings
Fig. 1 is the utility model overall structure schematic diagram.
Among the figure: 1-driven pulley, 2-stay hook, 3-slip ring, 4-drawing head, 5-support pulley, 6-overhanging cable, 7-lower pull rope, 8-drive, 9-traction electric machine, 10-sound insulation curtain, 11-traction control plate, 12-tunnel face, 13-massif, 14-pull rope.
The specific embodiment
The present invention is further described below in conjunction with accompanying drawing: as shown in fig. 1, described tunnel noise-proofing facility, comprise the sound insulation curtain 10 that is arranged on 12 outsides, tunnel face, sound insulation curtain draw-gear, traction control plate 11 and traction electric machine 9, described sound insulation curtain draw-gear comprises the driven pulley 1 that is arranged at both sides, top outside the tunnel face, drive 8, and drive and the pull rope 14 of loopy moving around described driven pulley 1 and drive 8 and by described drive 8, one end of described sound insulation curtain 10 and top, tunnel face body of wall stay hook 2 are fixing, the other end and described pull rope 14 fixedly become drawing head 4, the top of sound insulation curtain 10 is provided with a plurality of slip rings 3, and described slip ring 3 movable sets are on described pull rope 14; Described traction electric machine 9 drives described drive 8 forward and reverse rotations by reductor, so that described sound insulation curtain 10 is driven folding sound insulation curtain by described drawing head 4, the start and stop of described traction electric machine 9 and rotation direction are by described traction control plate 11 controls.
As embodiment, the mode of described traction control plate 11 by wired or wireless remote control is to described traction electric machine 9 signal controlling.Traction control plate 11 is by starting, stop by key control traction electric machine 9, and rotation direction, and the moving direction of the drawing head 4 by traction electric machine control sound insulation curtain namely control sound insulation curtain sealing tunnel face 12 reducing noise, or unlimited tunnel face is with convenient current.
According to the plan of establishment of above-described sound insulation curtain, the sound insulation curtain can be set to single width or double width.Pull rope 14 is around in driven pulley and the drive of both sides, forms the ring-type of a sealing, and the pull rope of ring-type has an overhanging cable 6 and a lower pull rope 7 all the time.
