In figure: 1 door cover plate, 2 handles, 3 secondary opening door hooks, 31 shape caps, 32 coupler bodies, 4 hydraulic servos, 41 upper connectors, 42 boosters, 43 times connectors, 5 fixed axis, 6 fire door stiles, 7 boilers, 8 seal washers, 9 hinges.
Detailed description of the invention:
As shown in Figure 1, a kind of secondary opening door, comprise door cover plate 1, handle 2, secondary opening door hook 3, hydraulic servo 4, fixed axis 5, fire door stile 6, seal washer 8 and hinge 9, described fire door stile 6 is welded on the fire door of boiler 7 upper surface, be welded with a fixed axis 5 in the middle part of the leading flank of fire door stile 6, be provided with hinge 9 in the rear end of fire door stile 6.The leading flank of described door cover plate 1 is welded with a handles 2, and be also provided with a secondary opening hook in the middle part, front end of door cover plate 1, the rear end of door cover plate 1 is connected with fire door stile 6 by hinge 9.Seal washer 8 is provided with at the lower surface of door cover plate 1.Described hydraulic servo 4 is arranged on the both sides of door cover plate 1 lower surface, and its top is connected with the front end of door cover plate 1, and its lower end is connected with boiler 7 upper surface.Described door cover plate 1 is rectangular metallic plate, and its material is carbon steel, is provided with a bar hole in its middle part, front end, in the middle of bar hole, longitudinally arrange a bearing pin, and secondary opening door hook 3 is arranged in bar hole by bearing pin.
As shown in Figure 2, the upper gib head of secondary opening door hook 3 hooks fixed axis 5, and now door cover plate 1 is locked.
As shown in Figure 3, the lower gib head of secondary opening door hook 3 hooks fixed axis 5, and now door cover plate 1 opens a bit of distance under the effect of hydraulic servo 4.
As shown in Figure 4, described secondary opening door hook 3 is made up of spherical caps and coupler body, and the top of coupler body is handle, and bottom is hook, installs a plastic spherical cap on the top of handle, both laborsaving during switch secondary opening door, right heat insulation, convenient operation.Described hook has two gib heads, namely goes up gib head and lower gib head, is provided with one section of perforate between upper gib head and lower gib head.When upper gib head hooks fixed axis 5, door cover plate 1 is locked.Instantly, when gib head hooks fixed axis 5, door cover plate 1 can open a bit of distance under the effect of hydraulic servo 4.
