Problems solved by technology

[0004] Although there are many kinds of slings used for hoisting reflector units, each sling can only lift reflector units of a certain size. At present, the sizes of reflector units of radio telescopes are different, and there are as many as 186 types of external dimensions. , therefore, when installing a radio telescope, it is necessary to frequently replace the spreader, resulting in low construction efficiency

Embodiment Construction

[0033] Embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0034] see figure 1 and figure 2 As shown, the embodiment of the present invention provides a special sling for hoisting the reflector unit of a radio telescope, including a hanger 1, a remote controller, 3 universal hanging claws 4, 3 steel wire ropes 5 and 2 remote control winches 3, The remote controller and the remote control hoist 3 are all wirelessly connected.

[0035] see figure 2 As shown, the hanger 1 is the main load-bearing structure. The hanger 1 includes a connecting plate 1a and three booms 1b located in the same plane. The included angles between the two booms 1b are equal, and are connected by reinforcing rods 1c. Each boom 1b is fixed with a lug 1d for hoisting the hanger 1, and the distance between each lug 1d and the center of the connection plate 1a is equal.

[0036] see figure 1 and figure 2 As shown, each boom ...

Abstract

The invention discloses a special lifting device and a lifting method for lifting a reflector unit of a radiotelescope and relates to the technical field of installation of reflector units of radiotelescopes. The special lifting device adopts the structure that a position-adjustable guiding pulley is arranged on each lifting arm, one end of each of two wire cables is connected with a remote-control windlass, and the other end of each of the two wire cables bypasses the corresponding guiding pulley; and one end of the third wire cable is connected with a hanging bracket, the other end of the third wire cable bypasses the corresponding guiding pulley, and a universal lifting claw is tied to each wire cable. The special lifting device and the lifting method can adapt to the lifting requirements of reflector units of different sizes to improve the construction efficiency.

Description

technical field [0001] The invention relates to the technical field of installation of a radio telescope reflector unit, in particular to a special hoisting tool and a hoisting method for hoisting a radio telescope reflector unit. Background technique [0002] The active reflector of the radio telescope installed this time is a spherical crown surface composed of 4,450 reflector units. Each reflector unit is a space grid structure with a triangular cross-section. The height of the reflector unit is about 1.3m. RMS≤2.5mm, the side length of the cross section is 10.4~12.4m. [0003] When installing a radio telescope, it is necessary to use a sling to hoist the reflector unit to the corresponding position on the cable net of the radio telescope and fix it. When all the reflector units are installed in place, the active reflector of the radio telescope will be formed. Among them, the reflector The three endpoints of the unit are node 0, node 1 and node 2 respectively. These thr...
