Abstract
The utility model relates to a plum-petal explosion-proof door for a coal mine shaft, providing an active safety device for a coal mine ventilation system and solving the serious problem that the coal mine shaft is blown up or damaged and cannot be restored in a short time, and the ventilation system is difficult to recover, after the underground explosion occurs in the prior art. The plum-petal explosion-proof door mainly comprises a door, a doorframe, hydraulic buffer devices or gas buffer devices and hinges, wherein the doorframe is polygonal, the door consists of triangular door leaves, the door leaves are hinged on the doorframe through the hinges, and the hydraulic buffer devices or the gas buffer devices are fixedly mounted outside the doorframe. The plum-petal explosion-proof door for the coal mine shaft has the advantages that: the plum-petal explosion-proof door is convenient in manufacture, transportation and mounting, the coal mine shaft can be rapidly restored, the ventilation system is rapidly recovered, the time for rescue and relief can be advanced, the casualties are reduced, and the loss caused by accidents is reduced, so that the explosion-proof performance and the safety function of the explosion-proof door are greatly improved.
Description
Technical field
The utility model belongs to coalmine ventilation system explosion proof door technical field, particularly a kind of coal mine shaft plum blossom lobe explosion proof door that is used for.
Technical background
Existing coal mine shaft door is the lid of general common form steel work; Do not have spacing resetting-mechanism, 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; 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, and then can't exhale pernicious gases, let the personnel of speedily carrying out rescue work lose and speedily carry out rescue work the relief time; Simultaneously also seriously jeopardize staff's life security under the coal mine, caused 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.Simultaneously, because original explosion proof door diameter is big, overall weight is big, and impact force is big, is difficult to control and cause, and is difficult for problems such as manufacturing, transportation and installation.
Summary of the invention
The purpose of the utility model is to overcome the shortcoming of prior art, provide a kind of can STRUCTURE DECOMPOSITION, component weight is lighter, is convenient to the coal mine shaft plum blossom lobe explosion proof door that transports and install.
The utility model is achieved in that
Coal mine shaft plum blossom lobe explosion proof door comprises door 1, door frame 2, hydraulic damping device or gas buffer 3 and hinge 4; It is characterized in that: described door frame is a polygon, and described door is made up of leg-of-mutton door leaf, and the quantity of door leaf equals the quantity on the polygonal limit of door frame, and door leaf is hinged on the door frame through hinge; The quantity correspondence of described hydraulic damping device or gas buffer 3 and the quantity of door leaf, and be fixedly mounted on outside the door frame.
Described coal mine shaft plum blossom lobe explosion proof door is characterized in that: also comprise foamed aluminium buffer 6; Wherein: described hydraulic damping device or gas buffer 3 are made up of with the bearing 3-2 that fixedly mounts oil buffer or gas cushion oil buffer or gas cushion 3-1; Described foamed aluminium buffer is fixedly mounted on the bearing.
The utility model substantive distinguishing features and beneficial effect are:
(1) plays buffer protection function through hydraulic damping device or gas buffer opposite house.
(2) door be decomposed into behind the multi-clove type door leaf can so that make, transportation and installing.
(3) after hydraulic damping device or gas buffer effect, if any dump energy, lean on the foamed aluminium buffer to absorb energy once more, further improve the effect of buffering.
The utility model has solved existing generation coal-bed gas blast back coal mine shaft and has been beaten and fly or break, and can't reset in the short time, is difficult to recover the serious problems of ventilation system; And have simple in structurely, safe and reliable, can reset fast; Make advantages such as ventilation system recovery, the time of the relief of can speedily carrying out rescue work in advance, reduce casualties; Reduce the loss that accident causes, thereby improved the explosion-proof performance and the safety effect of explosion proof door greatly.
Description of drawings
Fig. 1 is the structural front view of coal mine shaft plum blossom lobe explosion proof door.
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As depicted in figs. 1 and 2, coal mine shaft plum blossom lobe explosion proof door.It comprises door 1, framework 2, hydraulic damping device or gas buffer 3, hinge 4, sealing device 5, the foamed aluminium buffer 6 of door is installed; Described door frame is a polygon, and described door is made up of leg-of-mutton door leaf, and the quantity of door leaf equals the quantity on the polygonal limit of door frame, and door leaf is hinged on the door frame through hinge; The quantity correspondence of described hydraulic damping device or gas buffer 3 and the quantity of door leaf, and be fixedly mounted on outside the door frame.Described hydraulic damping device or gas buffer 3 are made up of with the bearing 3-2 that fixedly mounts oil buffer or gas cushion oil buffer or gas cushion 3-1; Described foamed aluminium buffer is fixedly mounted on the bearing.Described sealing device is installed on the framework.
Hydraulic damping device or gas buffer 3 that the utility model is installed on the framework absorb energy, and opposite house shields; When venting of dust explosion, under the effect of hydraulic damping device or gas buffer 3, as not absorbing energy fully, dump energy leans on foamed aluminium buffer 6 to absorb energy once more, and improves the effect of shutter; After blast, rely on the energy of the spring savings in hydraulic damping device or the gas buffer 3, impel door to return to position, lean on from repeats bits then less than 90 °.
Claims (3)
