Abstract
The utility model relates to a lightweight dome for astronomical observation. The spherical shell of a general dome for astronomical observation adopts a structure of a steel skeleton metal plate shell. The spherical shell of the dome is made of light materials, and a sprocket mechanical driving structure with a major diameter is designed to facilitate scene construction. The roller chains of a sleeve are respectively fixed on a peripheral face in the ring beam of the dome and the inner sector of a scuttle fan to form a sprocket ring (strip) and a sprocket driving mechanism in order to replace the rack-and-pinion drive. The structure of the spherical shell of the lightweight dome for astronomical observation is suitable for the structures of domes and analogous domes in various types and with various diameters, and the structure of the sprocket is suitable for various rotary type domes for astronomical observation.
Description
The utility model relates to a kind of light-duty astronomical observation dome.
General astronomical observation dome, its spherical shell housing normally adopts steel structure framework, outer illiteracy of skeleton the metal sheet shell is arranged, and nexine is hung sound-absorbing and decorative sheet, middle filling heat-barrier material; Adopt gear, rack for transmission mode.This structure is not only complicated and comparatively heavy, and it is big to make workload, the cost height.
This astronomical observation dome only is used for manufacturing of spherical shell with light material, and has designed the mechanical transmission mechanism that is applicable to different-diameter (particularly major diameter), is convenient to site operation.
The spherical shell of this light-duty astronomical observation dome has adopted the rigid foam through being processed into sphere to be made into body, makes outer reinforcement, waterproofing course with glass fiber reinforced plastic again, becomes composite construction.As required, global shell can be arranged to individual layer or bilayer.No matter individual layer or the double-deck global shell that is provided with all are fixed on the ring beam and become one.The arched girder that is used to support sash of skylight is fixed in ring beam, and (two arches are inboard) is provided with the track that can move for sash of skylight on its arched girder, and sash of skylight can move along its track by being installed on the driving of the drive unit on the arched girder, opens or close dome.In the outside of arched girder the ladder that is used to overhaul the skylight is housed, more than having constituted is the dome main body of supporting with the ring beam, that is top cover.Establishing one on the equal circumference on top cover ring beam bottom and the domed base top of being fixed in building can be for the raceway groove of steel ball rolling, place the steel ball of sufficient amount in the raceway groove, and guarantee that steel ball moves orderlyly, be by being arranged on the steel ball, it separated realization as retainer structure in the bearing.The dome top cover by the effect of top cover drive unit, is made circular motion on base under the supporting of steel ball, replaced conventional train supporting device with this steel ball supporting structure.But the steel ball rolling channel groove side on base is provided with the groove of a filling and sealing lubricating fluid, behind this groove and the raceway groove while topping up, steel ball and the annular plate washer of being located on the ring beam bottom all are immersed in the seal lubrication liquid, the resistance when reducing the top cover motion and increase it dynamically or the sealing under static.Motion joint at sash of skylight and sash of skylight track has designed a labyrinth seal structure simultaneously.
The fixed sprocket drive structure of chain has been adopted in the rotation of top cover and the keying of sash of skylight, that is adopt welding or riveted joint and other fixed forms that bushroller chain is fixed on it on the ring beam inner peripheral surface and in the sash of skylight on the covering of the fan, constituted respectively and be positioned at top cover ring beam inner periphery place and be equivalent to the ring gear effect, be equivalent to the effect of fan-shaped internal tooth bar on the sash of skylight covering of the fan etc. the chain gear ring of pitch radius and being positioned at, chain tooth bar etc. pitch radius, with respectively and be installed on the top cover drive unit of base, the drive sprocket that is installed on the sash of skylight drive unit on the ring beam is meshed, finish the rotation of dome top cover and the keying campaign of sash of skylight in a kind of special fixed chain drive mode of chain, replaced conventional rack-and-pinion drive structure.
Because the spherical shell of this astronomical observation dome has adopted light material, characteristics such as having good integrity, in light weight, heat insulation good, good waterproof performance, not corrosion, easily make, cost is low.
Owing to adopt bushroller chain to be fixed in by on the body of transmission thing, become the chain gear ring (bar) of (tooth bar) function that has gear, replaced the big modulus gear ring (bar) that needs heavy duty machine tools or particular method of manufacture to make, solved the machine driving problem of rotation of dome top cover and sash of skylight opening and closing preferably, have characteristics such as processing and manufacturing is simple, cost is low, wearing and tearing are little, be specially adapted to large diameter astronomical observation dome.
In the movable joint of ring beam and base and the movable joint of sash of skylight and its orbit, adopted sealing fluid and labyrinth sealing mode respectively, guaranteed abundant sealing to dome, prevented the pollution of dust to equipment in the dome; Adopt supporting and the rolling attachment of a large amount of steel balls as top cover, its supporting capacity greatly and vibrate for a short time owing to operate in the seal lubrication liquid, has reduced motion noise again, is specially adapted to manufacture large diameter dome rotating support body.
An embodiment of the light-duty astronomical observation dome of the basis that accompanying drawing provides.
Accompanying drawing 1: light-duty astronomical observation dome front view (under the sash of skylight opening).
Accompanying drawing 2: light-duty astronomical observation dome front view partial enlarged drawing I.
Accompanying drawing 3: light-duty astronomical observation dome front view partial enlarged drawing II.
