Description

Mine push-pull damper

technical field

The utility model relates to an adjusting damper in the technical field of mine ventilation.

Background technique

In underground mining mines, the air demand in the middle production section of the mine changes continuously with the transfer of the working face. Usually, ventilation structures are set on the return air side to adjust the air volume to achieve a reasonable distribution of air volume. In order not to affect pedestrians and adjust the air volume flexibly, and at the same time not be affected by the blasting shock wave, the mine has changed the way of setting a single air window adjustment. At present, most of the steel double-open air volume adjustment doors are used. However, it is still dangerous to switch the damper in the return air tunnel with large air volume and negative pressure, and it is difficult to fix the damper after it is opened. It is easy to damage the structure of the door body and cause the gasket to fall off, which affects the setting effect. In addition, this kind of The air volume adjustment range of the damper is small, so it is not suitable for mines where the air volume of the working face changes greatly.

Contents of the invention

The purpose of the utility model is to provide a mine-used push-pull damper, which overcomes the shortcomings of the conventional double-open damper, which are difficult to fix after opening, easy to damage the structure of the door body and cause the liner to fall off.

A mine-used push-pull damper, comprising a sliding door body, a door frame, shutters, pulleys, guide rails and buffer pads, characterized in that: the sliding door body is installed in the door frame, a shutter is set above the sliding door body, and at the same time The top and the bottom of the sliding door are respectively equipped with two double-sided pulleys, the top and bottom of the door frame are welded with guide rails, and the buffer pad is arranged on the contact surface between the door frame and the sliding door.

A mine-used push-pull damper, characterized in that it also includes a limit bolt, the limit bolt is recessed and installed under the right side of the sliding door body, and the surface of the guide rail at the bottom of the sliding door has a bolt hole.

The utility model relates to a push-pull adjustable damper for mining, which is characterized in that: the left side of the push-pull door adopts a T-shaped design.

The utility model has the advantages that the opening and closing direction of the new mining push-pull regulating damper body is perpendicular to the direction of wind flow or negative pressure, basically not affected by the air volume and negative pressure, simple structure, and safe design. The air volume can be adjusted and a certain blasting shock wave can be released by controlling the size of the closing space of the louvers and the air door. The air volume adjustment range is large, and it is suitable for mines with high blasting intensity and large changes in the required air volume on the working surface.

Detailed ways

Now describe in detail the implementation of the utility model structure in conjunction with the accompanying drawings:

A push-pull damper for mine use. The sliding door body 1 is installed in the door frame 2. The left edge of the sliding door body 1 adopts a T-shaped design, which is beneficial to prevent air leakage and ensure the stability of the damper. The left part of the door frame 2 is built in the wall 7, and the right part of the door frame 2 is embedded in the opening surface of the wall 7. In order to prevent the damage of the blasting shock wave, the surface of the wall 7 is poured with cement pebbles. The sliding door body 1 And door frame 2 adopts steel or other materials. The shutter 3 is arranged on the top of the sliding door body 1. When there is a blasting operation, the shutter 3 can be turned into an open state, which is beneficial to reduce the impact of the blasting impact on the adjustment damper. Simultaneously, two bilateral pulleys 4 are respectively installed on the top and the bottom of the sliding door body 1, the top and the bottom of the door frame 2 are welded with the guide rail 5, and the buffer pad 8 is arranged on the contact surface between the door frame 2 and the sliding door body 1 to avoid Damage from physical impact on the damper. The limit bolt 6 is installed in the depression on the right side of the sliding door body 1, the surface of the guide rail 5 at the bottom of the sliding door has a bolt hole 9, and the position of the sliding door body 1 is fixed by passing the limit bolt 6 through the bolt hole 9 , maintain the stability of the damper and control the ventilation volume.

The above content is a further detailed description of the utility model in combination with specific preferred embodiments, and it cannot be assumed that the specific implementation of the utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the utility model belongs, those who make several equivalent substitutions or obvious modifications without departing from the concept of the utility model, and have the same performance or use, shall be deemed to belong to the submitted utility model. The scope of protection determined by the claims.
