Abstract

The invention provides a winch lifting point device for a shielding room and a using method thereof. The winch lifting point device comprises a guide wheel (1), a shielding case (2), a winch lifting point shielding case (3), a stopping block (5), a steel wire rope (10), a winch (12) and a sheep eye lifting hook (7). One end of the steel wire rope (10) is connected with the winch (12) arranged on a winch bracket through the guide wheel (1), and the other end of the steel wire rope (10) is connected with the sheep eye lifting hook (7). The steel wire rope (10) penetrates through the winch hoisting point shielding case (3), the shielding case (2) is arranged between the steel wire rope (10) and the winch hoisting point shielding case (3), the steel wire rope (10) is provided with the stopping block (5), and travel switches are respectively arranged above and below the stopping block (5). The problem of hoisting point positioning of the winch is solved. According to the winch lifting point shielding device, a shielding case shell is arranged at the position where the steel wire rope passes through, and an automatic limiting device is installed in the case shell.

Description

technical field [0001] The invention relates to the field of electromagnetic shielding, in particular to a hoist lifting point shielding device for a shielding room and a method for using the same. Background technique [0002] At present, when conducting experiments in the high-voltage test hall, the test sample needs to be hung vertically in the air. Therefore, a hoist needs to be installed on the top of the hall, and the hoist wire rope needs to pass through the shielding layer on the top. This is equivalent to an antenna for the shielded hall. The external signal is introduced into the hall through the wire rope, which has a great impact on the overall shielding performance and will cause the shielded hall to lose its shielding function. Contents of the invention [0003] The invention provides a hoist lifting point shielding device used in a shielding room and a method for using the same. The purpose is to develop a new hoisting machine lifting point device to elimina...
