Abstract
A base portion 12 for supporting a segmented support column 14 of the telescope 10 is provided. A telescope mount 18 is located at a load bearing region 20 of the base portion 12. The mount 18 is mounted on three jacks 22 that permit raising of the mount 18 to permit a support column segment (not shown) to be inserted below the mount 18.
Claims
1. A method of erecting a radio telescope including at least the steps of: providing a base portion for supporting a segmented support column of the telescope; locating a telescope mount at a load bearing region of the base portion, the mount being mounted on one or more jacks; connecting a telescope collector to the telescope mount; mounting a support structure for a parabolic antenna on a hub of the telescope mount; and fitting panels to the support structure to form the parabolic antenna so that the panels are aligned to reflect a radio signal to the telescope collector; actuating the jacks into lifting the telescope mount through a height slightly higher than the height of one segment of the support column; and inserting a first support column segment between the telescope mount and the load bearing region of the base portion and securing said segment to the telescope mount whereafter the jacks are lowered and re-attached to the lowest support column segment of the support column; wherein the lifting of the telescope mount and support column segment(s) secured thereto and the lowering and re-attachment of the jacks is repeated as desired to permit the insertion of further support column segments until the support column has reached a desired height.
2. A method as claimed in claim 1 , wherein the base portion includes a plurality of open-topped ballast containers that are arranged to form a polygonal structure resting on the ground.
AMENDED SHEET (ARTICLE 19)
3. A method as claimed in claim 2, wherein the dimensions of the polygon are selected in accordance with the wind forces that the telescope is to withstand in use.
4. A method as claimed in claim 2 or claim 3, wherein each container is about 1,2 meters deep and is in use filled with sand, gravel, rocks, or any other suitable ballast material.
5. A method as claimed in any one of the preceding claims, wherein the load- bearing region of the base portion is located in a central region of the base portion.
6. A method as claimed in any one of the preceding claims, wherein the jacks are conventional hydraulic jacks.
7. A method as claimed in any one of the preceding claims, wherein three jacks are provided, which jacks are arranged so as to permit insertion of a support column segment once the jacks have completed their lifting action.
8. A method as claimed in any one of the preceding claims, wherein the jacks are attached to a base portion of the telescope mount by means of bolts passing through receiving formations provided on the base portion.
9. A method as claimed in any one of the preceding claims, wherein the telescope mount and the support column segments are provided with flanges extending circumferentially from free edges regions of the telescope mount and support column segments respectively.
10. A method as claimed in any one of the preceding claims, wherein once the first support column segment has been inserted between the telescope mount and the load bearing region of the base portion and secured to the telescope
AMENDED SHEET (ARTICLE 19)
16 mount, the jacks are lowered slightly to permit the first segment to rest on the load bearing region of the base portion so that the jacks can be removed from the base portion of the telescope mount.
11. A method as claimed in claim 10, wherein the jacks are as a next step attached to the first support column segment.
12. A method as claimed in claim 11 , wherein the first support column segment is provided with receiving formations spaced apart around its circumference, each receiving formation including an opening to permit attachment of the jacks to the segment.
13. A method as claimed in claim 11 or claim 12, wherein the jacks are as a next step actuated into lifting the telescope mount and the first segment secured thereto, through a height that is slightly higher than the height of one segment of the support column to permit insertion of a second support column segment between the first support column segment and the load bearing region of the base portion.
14. A method as claimed in any one of claims 11 to 13, wherein the lifting process, addition of support column segments, and removal and re- attachment of the jacks is repeated as often as desired until the desired height of the support column has been reached.
15. A method as claimed in any one of the preceding claims, wherein, when the desired height of the support column has been reached, a lattice framework and/or support struts extending between the base portion of the telescope mount and the base portion are erected in order to reinforce the support column.
AMENDED SHEET (ARTICLE 19)
17
16. A radio telescope erected in accordance with a method as claimed in any one of claims 1 to 15.
17.A method according to the invention for erecting a radio telescope substantially as hereinbefore described or exemplified.
18. A method of erecting a radio telescope including any new and inventive integer or combination of integers, substantially as herein described.
