Description

Iron pedestrian passageway

Technical Field

The utility model discloses iron pedestrian's passageway belongs to mine ventilation technical field.

Background

Usually in the colliery in the pit, there are a lot of horizontal rivers of contact between two adjacent crossheading roadways, in order to ensure mine ventilation system's stability, reliability, practicality, need be under the horizontal river of contact construction some ventilation facilities are used for cutting off the ventilation system in two adjacent roadways, these ventilation facilities have also hindered the passage of personnel and vehicle when having insulated two adjacent tunnel air currents, reach appointed task place in the very first time in order to reduce personnel and vehicle walking distance, need plan, have pointed to construct balanced air door in demand place, let personnel and vehicle pass on the shortest route. But the engineering volume is big in the balanced air door work progress, and is consuming time much, and the cost input is very high simultaneously.

Therefore, when a ventilation facility is constructed at a place where people do not need to pass through vehicles and only need to pass through, people need to be provided with the openings for people passing through, small-sized material transportation and the like, but a large amount of air leakage occurs after the people are provided with the openings, ventilation systems of two adjacent roadways are disordered, air current short circuit is caused, and the stability of a mine ventilation system is influenced.

As shown in figure 1, in order to solve the problem of air leakage through the doorway, a belt curtain made of waste belts can be used as a door leaf, and the air leakage is blocked under the condition of ensuring normal passing of people. Can be daily discover the leather curtain in the use and easily drop, cause the distinguished and admirable short circuit, the personnel need lift the leather curtain and keep normally open state and just can pass through when making a round trip to pass through moreover, use extremely inconveniently.

As shown in figure 2, can also reform transform into wooden door with the belt curtain, wooden door has solved easily and has fallen off, the current inconvenient problem of personnel, but single wall wooden door can not block up, and when personnel made a round trip to pass through, still can cause the distinguished and admirable short circuit, and wooden door fragile, especially under the big condition of negative pressure, the life of wooden door can shorten by a wide margin. If the safety and reliability of the ventilation system are ensured, two walls must be constructed at the same place, and two small doors passing through the human mouth can be manufactured to install the locking, so that the material cost is doubled.

SUMMERY OF THE UTILITY MODEL

The utility model discloses iron pedestrian's passageway has overcome the not enough of prior art existence, has satisfied the current requirement of wall distinguished the distinguished and admirable and personnel, and simple to operate is swift.

In order to solve the technical problem, the utility model discloses a technical scheme be: an iron pedestrian passageway is arranged in an underground roadway and comprises a rectangular parallelepiped frame consisting of an upper frame, a side frame and a bottom frame, wherein the top surface, the left side surface and the right side surface of the rectangular parallelepiped frame are covered by steel plates; the second wire rope is fixed with one point of the inner side of the front door.

Furthermore, a first nut is arranged on the outer side of the rear door and used for connecting the first steel wire rope, and a second nut is arranged on the inner side of the front door and used for connecting the second steel wire rope.

Further, handles are arranged on the inner side and the outer side of the front door, and handles are arranged on the inner side and the outer side of the rear door.

Furthermore, the front door is hinged with the frame through a hinge, the rear door is hinged with the frame through a hinge, and the opening directions of the front door and the rear door are consistent.

Compared with the prior art, the utility model following beneficial effect has.

The utility model discloses can cut off the wind current, also can satisfy the current requirement of personnel, the material cost drops into lowly simultaneously, avoids causing the wind current short circuit. The utility model discloses firm, adopt the design of integration to make the simple installation, realize ventilation facility's essence safety.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in fig. 3-6, an iron pedestrian passageway is arranged in an underground roadway and comprises a rectangular parallelepiped frame consisting of an upper frame 1, a frame 2 and a bottom frame 11, wherein the top surface, the left side surface and the right side surface of the rectangular parallelepiped frame are covered by steel plates, the front surface of the rectangular parallelepiped frame is provided with a front door 3, the back surface of the rectangular parallelepiped frame is provided with a rear door 10, the right side surface of the rectangular parallelepiped frame is provided with a locking device 6 and a threading hole 12, the right side of the rear door 10 is provided with a pulley 7, the locking device comprises a first steel wire rope 61 and a second steel wire rope 62, and the first steel wire rope 61 passes through the threading hole 12 and is fixed with one point on the outer side of; the second wire rope 62 is fixed to a point on the inner side of the front door 3.

A first nut 8 is arranged on the outer side of the rear door 10 and used for connecting a first steel wire rope 61, and a second nut 9 is arranged on the inner side of the front door 3 and used for connecting a second steel wire rope 62.
