Abstract
The utility model designs a mine roadway support door, which comprises: a bracket door device and a cast iron bolt device. The support door device consists of a support, a rotating shaft and a supporting beam. The cast iron bolt device consists of a cast iron bolt and a pin. The rotating shaft is fixedly arranged on the support, the supporting beams are rotatably arranged on the rotating shaft, the two supporting beams are connected through cast iron bolts, the horizontal postures of the two supporting beams are kept, and the cast iron bolts and the supporting beams are fixed through pins. Under the condition that the mine roadway collapses, the supporting beams are stressed to break the cast iron bolt with poor material elasticity, so that the two supporting beams are displaced, the supporting beams are inclined, a stable supporting triangular state is formed, and the supporting protection effect is achieved. According to the utility model, through the interaction of the support door device and the cast iron bolt device and the combination of special materials of the cast iron bolt, after the roadway is collapsed, the cast iron can be fractured, so that the device is deformed into a triangular state, the effect of protecting workers is achieved, and the support door device has the advantages of simple structure, ingenious design and the like.
Description
Technical Field
The utility model relates to a support door, in particular to a mine roadway support door.
Background
In a mine roadway, the time of roadway collapse frequently occurs, great threat is caused to the life and property safety of workers, in order to ensure the life safety of the workers temporarily under the extreme dangerous condition of the collapse, an emergency device is urgently needed to be developed, and the life safety of the workers can be fully ensured under the condition of the roadway collapse.
Disclosure of Invention
The utility model aims to provide a mine roadway support door, which can be applied to various mine roadway collapse scenes and is used for temporarily supporting and protecting the life safety of workers.
The above technical problem of the present invention is solved by the following means.
The utility model discloses a mine roadway support door, which is characterized in that: the mine roadway support door consists of a support door device and a cast iron bolt device.
The support door device consists of a support (1), a rotating shaft (2) and a supporting beam (3).
The cast iron bolt device consists of a cast iron bolt (4) and a pin (5).
The rotating shaft (2) is fixedly installed on the support (1), the supporting beams (3) are rotatably installed on the rotating shaft (2), the two supporting beams (3) are connected through the cast iron bolt (4), the two supporting beams (3) are kept in a horizontal posture, and the cast iron bolt (4) is fixed with the supporting beams (3) through the pin (5). Under the condition that the mine roadway collapses, the supporting beams are stressed to break the cast iron bolt with poor material elasticity, so that the two supporting beams are displaced, the supporting beams are inclined, a stable supporting triangular state is formed, and the supporting protection effect is achieved.
According to the utility model, through the interaction of the support door device and the cast iron bolt device and the combination of special materials of the cast iron bolt, after the roadway is collapsed, the cast iron can be fractured, so that the device is deformed into a triangular state, the effect of protecting workers is achieved, and the support door device has the advantages of simple structure, ingenious design and the like.

Detailed Description
For a better understanding and appreciation of the structural features and advantages achieved by the present invention, reference should be made to the following detailed description taken in conjunction with the accompanying drawings, in which:
as shown in figures 1 and 2, the mine roadway support door consists of a support door device and a cast iron bolt device.
The support door device consists of a support (1), a rotating shaft (2) and a supporting beam (3).
The cast iron bolt device consists of a cast iron bolt (4) and a pin (5).
The rotating shaft (2) is fixedly installed on the support (1), the supporting beams (3) are rotatably installed on the rotating shaft (2), the two supporting beams (3) are connected through the cast iron bolt (4), the two supporting beams (3) are kept in a horizontal posture, and the cast iron bolt (4) is fixed with the supporting beams (3) through the pin (5). As shown in fig. 5, when the mine roadway is collapsed, the supporting beams are stressed to break the cast iron bolt with poor elasticity, so that the two supporting beams are displaced, the supporting beams are inclined, a stable supporting triangular state is formed, and a supporting protection effect is achieved.
According to the utility model, through the interaction of the support door device and the cast iron bolt device and the combination of special materials of the cast iron bolt, after the roadway is collapsed, the cast iron can be fractured, so that the device is deformed into a triangular state, the effect of protecting workers is achieved, and the support door device has the advantages of simple structure, ingenious design and the like.
The foregoing shows and describes the general principles, essential features, and advantages of the utility model. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the utility model, but that various changes and modifications may be made without departing from the spirit and scope of the utility model, which fall within the scope of the utility model as claimed. The scope of the utility model is defined by the appended claims and equivalents thereof.
