Abstract
The utility model discloses a tunnel kiln gate safety device, which comprises a kiln gate which slides up and down in a gate frame in a sliding way; a locating sleeve is horizontally arranged at the upper part of the gate frame; a push-pull bolt which goes through the locating sleeve is arranged in a movable matching way; and one end of the push-pull bolt which is arranged on the inner side of the gate frame is provided with a U-shaped hook extending into a tunnel kiln. The tunnel kiln gate safety device has the advantages of convenient operation and capability of effectively locating the open kiln gate reliably. During use, after the kiln gate is opened, the push-pull bolt is rotated, so that the U-shaped hook on the end extends and enters the gate frame to locate the kiln gate; when kiln gate is closed, the push-pull bolt is rotated in a reverse direction to rotate the U-shaped hook on the end out of the gate frame, thereby preventing the kiln gate from suddenly sliding down.
Description
Technical field
The utility model relates to the tunnel wicket, especially relates to the tunnel cave door safety device.
Background technology
Tunnel cave must upwards be mentioned the location with wicket in turnover material process, so that the turnover of track kiln car.At present wicket is mentioned Mechanical Driven or the electric type of drive of adopting more, but accidents caused because power failure or mechanical breakdown will cause wicket to fall.
The utility model content
The utility model purpose is to provide a kind of tunnel cave door safety device that prevents that wicket from gliding suddenly.
For achieving the above object, the utility model can be taked following technical proposals:
Tunnel cave door safety device described in the utility model, it comprises and slides up and down the wicket that is arranged in the doorframe chute; Be provided with positioning sleeve at described doorframe upper level, run through described positioning sleeve and be provided with push-and-pull in mode movingly and fasten, fasten an end that is positioned at the doorframe inboard in described push-and-pull and be provided with the U-shaped hook that tilts to extend to tunnel cave.
The utility model advantage is easy to operate, can effectively the wicket of opening reliably be located.During use, after wicket is opened, rotate described push-and-pull and fasten the U-shaped hook that makes its end and extend in the doorframe wicket is located; In the time of need falling wicket, the counter-rotation push-and-pull is fastened U-shaped hook with its end and is rotated outside the doorframe and get final product; Thereby stopped glide the suddenly generation of phenomenon of wicket.
