| 摘要 |
The present invention relates to an ice guard (2) for facilitating the breaking-up of ice formations in conjunction with the use of turntables (1), and for protecting mechanical parts of an apparatus platform (4) from mechanical stresses, the platform being able to be tilted selectively in relation to a supportive surface (3). The ice guard (2) functions to protect mechanical parts of the apparatus platform from ice formations, among other things. The ice guard is comprised of a bellows structure (23) which surrounds mechanical parts of the apparatus platform (4) from the supportive surface (3) up to the apparatus platform (4). One end of the bellows structure (23) is firmly attached to the supportive surface (3) and the other end of the bellows structure extends up to the apparatus platform (4). In a first instance, in which the apparatus platform (4) is non-rotatable, the ice guard (2) includes a cover plate (19) to which the aforesaid other end of the bellows structure (23) is attached. In a second instance, in which the apparatus platform (4) is rotatable, the bellows structure (23) is attached to a bearing (26) between the aforesaid other end of the bellows structure (23) and the periphery of the apparatus platform (4). |
