JP3018657U - Soundproof door for tunnel construction - Google Patents

Abstract

(57) [Summary] [Objective] The present invention relates to a door for preventing noise caused by tunnel construction. [Structure] A unit panel (1) that rotates and has a ventilation port is provided on the upper part of the tunnel, and a three-stage lock bar lock device (7) is operated by a manual winch (10), and a damper ( 12) is attached.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This is a soundproof door that prevents the noise generated by various tunnel excavation works, in pursuit of improvement of the work environment after installation, safety, and higher soundproofing effect.

[0002]

[Prior art]

 The dust generated in the conventional tunnel construction accumulates at the top of the tunnel, and even if it is blown into the mine by a contra fan for ventilation, the dust collected at the top was difficult to come out of the tunnel mine. The door lock device for the door panel of the Kannon type, which is the entrance and exit of trucks, etc., used Kannuki and lifted it using the lever principle to operate the door lock device. Since Kannuki uses heavy members, it was difficult to stop and open and close the door panel while lifting. In tunnel excavation work using the blasting method, the high degree of airtightness of soundproof doors is required, but the blasting noise (about φ900 to φ1500 mm) was left open, so blasting noise was generated in the tunnel pit. It leaked to the outside and reduced the effectiveness of the soundproof door.

[0003]

[Problems to be solved or solved]

 The present invention eliminates the drawbacks, improves the soundproofing effect, improves the working environment associated with the purification of tunnel tunnels, and ensures the safety when installing and using the soundproofing door, improving it to a versatile soundproofing door. Is what you are trying to do.

[0004]

[Means for Solving the Problems]

 The solution means will be described with reference to the drawings. (A) A unit panel (1) installed on the top of a soundproof door and capable of rotating and having a ventilation opening is constituted by a frame part (2) and a rotating part (3). Remove the wire (5) from the connecting rod (4) attached to the part and wind the wire with the manual winch (6) to rotate the vertical rotating part until it becomes horizontal and open the ventilation port. To do so. (B) When opening and closing the Kannon type door panel, the wire (9) is attached to the cannon bar to lift the cannon bar (8) of the three-stage cannever bar lock device (7), and the hand winch (10) is rolled up to lift the cannever bar. So that it lifts and disengages from the receiver. (C) A damper (12) that closes the through-hole when the blast occurs is attached to the through-hole (11) for the wind pipe.

[0005]

[Action or Example]

 With the present invention, the dust collected in the upper part of the tunnel mine quickly flows out of the tunnel mine by the ventilation opening of the soundproof door. By using a manual winch to operate the three-stage lock bar, the door lock can be released with a small amount of human power, and since the lock bar can be fixed in the lifted state, the door panel can be easily opened and closed. A damper was attached to the through hole for blowing air to close the through hole when blasting, and the through hole was opened when using the contrafan.

[0006]

[Effect of device]

 Therefore, the unit panel with a rotating and ventilation port installed above the soundproof door makes it easier for the dust collected in the upper part of the tunnel mine to go out of the tunnel mine, helping to clean the inside of the tunnel mine and improving the working environment. It was Regarding the opening and closing of the door panel, a manual winch was used to operate the three-stage lock bar lock device, making safe and easy work possible. In addition, the soundproof effect of the entire soundproof door could be enhanced by the damper attached to the through hole for ventilation.
