Abstract
The utility model relates to a self-weight reset anti-explosion door of a vertical shaft, belonging to a coal mine ventilation safety device, and aiming at solving the problem that after the pressure of the anti-explosion door of the vertical shaft is released, two door leaves are easily damaged and can not be reset in time. The self-weight reset anti-explosion door of the vertical shaft comprises a wedge-shaped beam arranged at a wellhead, and is characterized in that the center of the wedge-shaped beam is provided with a rotary seat; the rotary seat is provided with a hinge used for articulating the two leaves of the anti-explosion door which are supported on a base; the base is fixed on the foundation of the wellhead; and the anti-explosion door is provided with a buffer material. The self-weight reset anti-explosion door is used for the coal mine air shaft, not only is capable of eliminating the potential safety hazard of the anti-explosion door, but also has the advantages of being simple in structure, safe and reliable.
Description
Technical field
The utility model relates to the coalmine ventilation safety device, and particularly a kind of vertical shaft middle open type is from the repeats bits explosion proof door.
Technical background
The explosion proof door of ventilating shaft is the explosion proof door of general common door form steel work in the existing coalmine ventilation safety device; In a single day run into the situation that well shooting takes place in the colliery; Explosion proof door very easily is destroyed or flies away from well head, and explosion proof door can't reset at short notice, will cause like this and can't recover within a short period of time under the coal mine to ventilate; Thereby can't exhale pernicious gases; Let the personnel of speedily carrying out rescue work lose and speedily carry out rescue work the relief time, also seriously jeopardized staff's life security under the coal mine simultaneously, cause the disaster after accident takes place to enlarge.For this reason, the colliery presses for the explosion proof door that has more safety that can in time reset that research and development are used for the coalmine ventilation well.
Summary of the invention
The purpose of the utility model is to overcome the prior art shortcoming, provides the vertical shaft that there is padded coaming at a kind of door leaf back from the repeats bits explosion proof door, solve existing vertical shaft explosion proof door pressure release after, door leaf is destroyed and problem such as the difficulty that resets easily.
The utility model is realized through following technical scheme:
A kind of vertical shaft is from the repeats bits explosion proof door; Comprise: the tapered beam that is arranged on well head; It is characterized in that: the central authorities of said tapered beam are equipped with revolving bed, and said revolving bed is provided with the hinge of hinged two fan explosion proof doors, and the said explosion proof door of two fans is bearing on the base; Said base is fixed on the well head basis, on the said explosion proof door padded coaming is installed.
The utility model compared with prior art; Owing to take the middle open type structure; On the two fan explosion proof doors padded coaming is installed; When explosion proof door was opened by impact generated by explosion ripple or high pressure draught, two fan explosion proof doors rotated head-on collision around hinge axis, and the padded coaming that is installed on the explosion proof door is compressed the absorption impact energy.Door leaf can be from horizontal reset under the deadweight effect after the pressure release.The utility model is used for coal mine air-shaft, realized explosion proof door from horizontal reset, so just can recover within a short period of time to ventilate; The time of speedily carrying out rescue work in advance and succouring; Reduce casualties, reduce the loss that accident causes, thereby improved the explosion-proof performance and the safety effect of explosion proof door greatly; Not only can eliminate the potential safety hazard of explosion proof door, and have simple in structure, safe and reliable advantage.Simultaneously, the resistance coefficient of tapered beam is little, helps releasing of impact generated by explosion ripple or high pressure draught, reduces the destruction to beam.

Fig. 1 is the structural representation (front view) of the utility model;
Fig. 2 is the vertical view of Fig. 1.
The utility model is described further through embodiment below in conjunction with accompanying drawing.
The specific embodiment
As shown in Figure 1; A kind of vertical shaft comprises from the repeats bits explosion proof door: be arranged on the tapered beam 4 of well head, the central authorities of said tapered beam 4 are equipped with revolving bed 3; Said revolving bed 3 is provided with the hinge 5 of hinged two fan explosion proof doors 2; The said explosion proof door 2 of two fans is bearing on the base 1, and said base 1 is fixed on the well head basis, and padded coaming 6 is installed on the said explosion proof door 2.
