FAST Active Reflector is made up of collar tie beam, reflecting surface, rope net, actuator, earth anchor etc., and structural representation can referring to Figure of description 1.Rope net is arranged on collar tie beam, has 2225 nodes, and rope net node is installed 4450 reflecting surface unit of having an appointment and forms reflecting surface, be connected with downhaul and actuator below each node, actuator is connected with earth anchor again.By controlling actuator, realizing 300 meters of instantaneous parabolas of bore and carrying out celestial observation.
Reflecting surface unit is divided into triangle and the large class of quadrangle two, wherein triangle reflecting surface unit is space grid structure, the length of side is about 10.4 ~ 12.4 meters, and be made up of backrest, setting device, panel and connection joint etc., each triangle reflecting surface unit weight is about 500 kilograms.Reflecting surface unit backrest is all equipped with and connects joint on summit, is suspended on rope forms glass reflecting surface on the net by these joints.Reflecting surface unit lifting be by all reflecting surface unit by hanging device handling to rope net assigned address, make connection joint and the rope net node assembly connection at reflecting surface unit summit place, form glass reflecting surface.
Adopt the reflecting surface unit of Special Hoisting equipment hoisting, itself there is certain rigidity, for reducing hoisting process to the impact of reflecting surface unit surface figure accuracy as far as possible, on reflecting surface unit top, one rigidity suspender is set, consider reflecting surface unit aerial statue, panel area, the problems such as the motion space of end bar in upper layer disc, the connection mode of reflecting surface unit and suspender wants succinct, rationally, reliably, avoid and other constructive interferences, the panel area at unit summit place can not be reduced again, and ensure that each reflecting surface unit has respective aerial statue etc., it is also one of the gordian technique of lifting construction that reflecting surface unit is connected with suspender.Traditional suspension centre form with above-mentioned requirements contradiction, the demand of reflecting surface unit lifting can not be met, need badly exploitation a kind of Novel spider plant point apparatus.
Utility model content
For problems of the prior art, the utility model provides a kind of novel FAST reflecting surface unit design of lifting points form.Reflecting surface unit design of lifting points is at the connection joint of unit side bar, be rigidly connected with end bar, when lifting reflecting surface unit, lifting-point device is connected with suspender, dismantle lifting-point device after this reflecting surface unit is installed, by this new design, achieve the simple, reliable, convenient, reasonable of lifting-point device, not with other constructive interferences, do not reduce unit summit place panel area, do not affect end bar and the motion space of joint on father of node dish yet.
The purpose of this utility model is achieved through the following technical solutions:
For the lifting-point device of FAST reflecting surface unit lifting, comprise reflecting surface unit summit place end bar, described end bar is connected with reflecting surface unit backrest, described end bar arranges detouchable hanger, hanger is rigidly connected with end bar, and hanger top, with connecting bore, is connected with suspender by connecting bore; After to be reflected cellular installation completes, disassemble described hanger.
Further, one end that described end bar is connected with hanger is provided with axial internal thread hole, described hanger is plate shape, be provided with through hole up and down, upper through-hole forms described connecting bore and is connected with suspender, lower through-hole forms fixed orifice, is fixed on the outer face of end bar by described hanger by bolt and pad.
Further, described hanger upper and lower side all arranges fillet.
The reflecting surface unit of above-mentioned suspension centre form is adopted to have the following advantages:
Lifting-point device is arranged on unit side bar place, be rigidly connected with end bar, when lifting reflecting surface unit, suspension centre is connected with suspender, can dismantling lifting-point device after having lifted, by which solves lifting hanging point problem, achieving the simple, reliable, convenient, reasonable of lifting-point device, not with other constructive interferences, do not reduce unit summit place panel area, do not affect end bar and the motion space of joint on father of node dish yet.
