In figure: terraced beam 1, handrail 2, handrail upright bar 201, arm rest cross bar 202, hanger plate 3, platform board 4, guardrail 5, fixed frame
Frame 6, Z-type support 6-1, position sealing plate 7, spiral case 8, stair tread 9, snap ring 10, rotating fulcrum 11, pin shaft 12, supporting beam 13.
Specific embodiment
As shown in Figure 1-3, a kind of water turbine set spiral case door is made into helper of aluminum alloy material, including terraced beam 1, help
Hand 2, guardrail 5 and fixed frame 6.
Specifically, the terraced beam 1 includes the supporting beam 13 of the plate of left and right, the connection of two supporting beams, 13 middle bolt fastening or welding
There is stair tread 9, the disengaging for service personnel is walked about up and down, and 9 surface of stair tread is printed on the spray of molten steel, avoids skidding.
The handrail 2 includes handrail upright bar 201, arm rest cross bar 202, and 201 lower end of handrail upright bar passes through with supporting beam 13
It is bolted, easy to disassemble, 201 upper end of handrail upright bar is connect by screw thread with rotating fulcrum 11, and rotating fulcrum 11 passes through pin
It is connect with snap ring 10, snap ring 10 can be around pin rotation, and 10 sets of snap ring on arm rest cross bar 202, can glide on arm rest cross bar 202
It is dynamic.By the way that rotating fulcrum 11 and snap ring 10 is hinged, the position of adjustment arm rest cross bar 202 can be facilitated.
In practical application year, two o'clock convenience can be brought in installing and dismounting by being rotatably connected: first, rotatably connect
Space can be saved by connecing, handrail is fashionable, handrail upright bar 201 can be rotated it is parallel with arm rest cross bar 202, it is original in spiral case door
Under conditions of less, bring convenience.If snap ring is not able to rotate, handrail upright bar 201 only has a kind of vertical position state, is removing
Larger space is occupied in fortune, installation.Second, during the installation process, accurate adjustment snap ring 10 can not had to due to being rotatably connected
Position increase the aspect of installation as long as handrail upright bar 201 is i.e. mountable vertically.
The guardrail 5 includes the notched hollow frame in left and right, and hollow frame lower end indentation, there is equipped with bolt font
Frame is put together on positioning framework 6 by bolt.
The Z-type of the fixed frame 6 including the left and right sides supports 6-1, and two Z-types support the one end 6-1 to be equipped with notch, at notch
Equipped with pin shaft 12.3 one end of hanger plate is hung on pin shaft 12, the other end and 13 bolt of supporting beam are fixed.And two Z-types support 6-1
The other end is welded with positioning sealing plate 7, and positioning on sealing plate 7 has bolt hole, and has on corresponding spiral case doorframe for fastening spiral case door
Bolt hole, therefore position sealing plate 7 can be fixed by bolt and spiral case doorframe.It is welded on two Z-types support 6-1 lower horizontal plane
Platform board 4 with the spray of molten steel facilitates maintenance personal to enter from spiral case doorway.Fixed frame 6 by Z-type support 6-1 lower fulcrum and
7 bearing's load of sealing plate is positioned, guarantees the stability of whole device.
As illustrated in figures 4-5, in addition, being provided with through slot 14 at 3 leading hook of hanger plate, in 3 lower end main part of hanger plate
It is drilled with jack 15, top plate 16 is connect by spring 17 with 15 bottom surface of jack, and 16 other end of top plate is extend into through slot 14.Work as hook
Before plate 3 hangs over pin shaft 12, top plate 16 is first depressed, after hanger plate 3 is hung on pin shaft 12, decontrols top plate 16, top plate 16 is inserted into logical
Spacing collar can be formed in slot 14 with hanger plate 3, it is firm that guarantee is hung, and terraced beam 1 is avoided to be detached from, and guarantees safety.
Operation principle and process:
1), fixed frame 6 is fixed by bolts on spiral case doorframe.Before fastening bolt, the position of fixed frame 6 is adjusted
It sets, keeps 6 position of fixed frame horizontal, allow the lower fulcrum of fixed frame 6 to contact with spiral case 8, then fastening bolt.
2), it is divided to or so two pieces to connect by bolt with ladder beam 1 hanger plate 3.
3), the terraced beam 1 with hanger plate is put into spiral case 8 from spiral case door, the hook of hanger plate 3 is hung on pin shaft 12, it is left
Right shaking, to check whether overlap joint robust.
4), guardrail 5 and handrail 2 are separately fixed at bolt to the both sides of fixed frame 6 and terraced beam 1, and check whether jail
Gu reliable.Handrail 2 can also adjust position by snap ring 10.
