The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described;
In conjunction with Fig. 1-Fig. 4;
It is cylindrical structural that described leading screw 5 has an end of pin-and-hole 9.
The equilateral structure of described leading screw 5 is hexagon.
The middle part diameter of described leading screw 5 is greater than the diameter at two ends.
Being reduced to the both sides staged by the centre of described leading screw 5 diameters.
Comprise the hatch door system that is installed on the cabin body 8, described hatch door system comprises leading screw 5, described leading screw 5 is connected connection with door shell also can be in door shell 2 inner rotation, one end of described leading screw 5 has switching system, described switching system comprises screw thread and is installed in force transmission element 6 on the leading screw, between described force transmission element 6 and the door shell 2 spring 3 is arranged, the outside of described force transmission element 6 is connected with more than one wiper seal bar 8, also comprise fulcrum cross bar 4, consist of mobile space between fulcrum cross bar 4 and the door shell 2, described wiper seal bar 8 stretches in the mobile space and can rotate along with the rotation of force transmission element 6, described wiper seal bar 8 is installed on the force transmission element 6 and can rotates around horizontal rotating shaft by horizontal rotating shaft, described wiper seal bar 8 when a side of mobile space between fulcrum cross bar 4 and cabin body 8.
The end that described wiper seal bar 8 stretches into mobile space also comprises the column type hold-down head, and the axis of cylindrical hold-down head is perpendicular to the axis of wiper seal bar 8.
Described leading screw 5 is switching system at an end of door shell 2, and the other end is installed with handwheel 1.
Cover has round nut braking collar on the described leading screw 5, the shift motion of force transmission element 6 on leading screw that restriction is installed,
Described handwheel 1 and leading screw 5 are connected, and drive during hand wheel rotating that force transmission element 6 rotates and axially-movable exists simultaneously, horizontal movement at the extreme position of mobile space between fulcrum cross bar 4 and cabin body 8.
Leading screw 5 mainly is to consist of the lead screw transmission pair with force transmission element 6 in the escape door transmission system, the rotation of handwheel 1 is become moving axially of force transmission element 6, power on the handwheel 1 amplifies through leverage the most at last, be connected at the handwheel 1 of leading screw 5 one ends with the escape outside during design, the other end is designed to interior hexagonal structure, mainly be to consider the in the future installation of heat-barrier material, because the mounting means of the installation of escape heat-barrier material and explosion proof door heat-barrier material is different, the installation of escape heat-barrier material adopts the individual layer straight cutting to install, and is to adopt heat shield directly after first hatch door being closed and the escape opening fastens.Force transmission element 6 mainly is Bonding pressure seal bar 8, uses pin to be connected with wiper seal bar 8, is designed with the butter hole in the junction, will inject butter before work.This is located described pin and is horizontal rotating shaft.
The leverage that has connected and composed the transmission system most critical of wiper seal bar 8 and force transmission element 6, the Front-end Design of wiper seal bar 8 has the column type hold-down head, mainly is in order to increase the contact area with hatch door body edge, to realize all and pressurized.Wiper seal bar 8 mainly is by forging, the fulcrum of leverage is a semicolumn cross bar, the scope of activities of wiper seal bar is subject to certain restrictions, mainly be subject to the restriction of L, H, L represents the maximum linear displacement that wiper seal bar 8 rotates in circular flat, H represents the maximum height that wiper seal bar 8 is is axially rising and falling.Being designed with a spring between force transmission element 6 and leading screw 5 shaft shoulders, mainly is to give the power transmission diskware pre-pressing force, and wiper seal bar 8 can move in the L scope when realizing the leading screw rotation.
Mine escape capsule escape operating principle is as follows, what the wiper seal bar was in when escape are in opening is the opening that hatch door body doorframe edge goes out, this moment, wiper seal bar 8 seal head placed under the rectangular frame above the side rod, and spring contacts with force transmission element 6, and thrust is larger.When clockwise rotating handwheel 1, because the existence of thrust, the power transmission diskware also turns clockwise when lead screw transmission axially rises, driving the wiper seal bar moves clockwise, final pressure seal bar 8 is because the restriction of framework rests on this place, this moment, bottom, the wiper seal bar face of cylinder was on hatch door body doorframe inward flange plane, this moment, force transmission element 6 still rose, wiper seal bar 8 is rotated counterclockwise round the pin that force transmission element 6 is connected, the wiper seal head then moves downward, power is through the amplification of leverage like this, and the contact force at Three pressures seal head and hatch door body edge becomes greatly gradually, and escape are realized locking the most at last.When opening escape, be designed with interior hexagonal deep hole at the other end of leading screw 5, the escape personnel finally can open escape by means of rotating counterclockwise leading screw at the inner hexagonal head wrench of cabin body.
Above demonstration and described basic principle of the present utility model, principal character and advantage of the present utility model.Those skilled in the art should understand the utility model and not be restricted to the described embodiments; that describes in above-described embodiment and the manual just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in the claimed scope.
