Embodiment Construction

[0031] The technical solutions and beneficial effects of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0032] Such as figure 1 and figure 2 As shown, a new type of sliding gantry crane for GIS installation and maintenance, mainly including main beam 1, support beam 13, top slide rail 2, electric sliding trolley 3, electric chain hoist 4, power supply cable 10, control line 14. Controller 15, triangular bracket 17, roller 21, etc. Wherein, the main beam 1 is arranged transversely in the middle of the gantry crane, and the support beams 13 are arranged longitudinally at both ends of the main beam 1 for supporting the main beam 1 . The top slide rail 2 is welded under the main beam 1, and the electric sliding trolley 3 is suspended below the top slide rail 2 through the cooperation of the trolley running device 8 and the top slide rail 2, and can move along the slide rail 2; the top slide rail 2 ...

Abstract

The invention relates to a novel sliding-type gantry crane and a use of the novel sliding-type gantry crane in hoisting of GIS equipment. The novel sliding-type gantry crane comprises a main beam part, a control part and a support part. The main beam part comprises a main beam which is transversely arranged in the middle of the novel sliding-type gantry crane, a two-end support beam which is longitudinally arranged at two ends of the main beam and used for supporting the main beam, a top sliding rail which is fixedly arranged under the main beam, an electrically sliding trolley which is hung at a lower part of the top sliding rail and moves along the top sliding rail, a trolley traveling device which is in a fit relationship with the top sliding rail and is used for assisting the electrically sliding trolley to slide along the top sliding rail, an electrically hoisting chain calabash which is arranged under the electrically sliding trolley and used for moving hoisting equipment upward / downward, and a control part which is used for controlling the electrically sliding trolley to move and controlling the electrically hoisting chain calabash to rise and fall. The novel sliding-type gantry crane has the advantages of small volume, light weight, flexible movement, mounting / dismounting convenience, and flexible use.

Description

technical field [0001] The invention specifically relates to a novel sliding gantry crane and its application, and belongs to the field of installation and maintenance of GIS equipment. Background technique [0002] In the power industry, GIS is the abbreviation of "Gas Insulated Switchgear" (Gas Insulated Switchgear), which refers to all equipment in a substation except transformers, including circuit breakers, disconnectors, grounding switches, voltage transformers, and current transformers. , surge arrester, busbar, cable terminal, inlet and outlet bushing, etc., are organically combined into a whole through optimized design, which is the switch station that we often see, also called high-voltage power distribution device. [0003] GIS is high-voltage electrical equipment with high operational reliability, less maintenance workload, and long maintenance cycle. Its failure rate is only 20% to 40% of conventional equipment, but GIS also has its inherent shortcomings. Due to...
