A miniature crawler crane for substation maintenance

Abstract

The present invention relates to the technical field of substation lifting devices, in particular to a miniature crawler crane vehicle for substation maintenance, including a chassis vehicle system and a lifting device system arranged on the chassis vehicle system, and the chassis vehicle system includes a steel structure Vehicle frame and the power device, outrigger device, slewing device and running device arranged on the steel structure frame; the power device includes an engine and a gear pump, and the engine is installed at the front of the steel structure frame, The engine is connected with the gear pump; the lifting device system includes a lower arm structure arranged on the chassis vehicle system and an upper arm structure connected with the lower arm structure, and the upper arm structure is hydraulic or electric Multi-section folding structure. Through the application of the novel equipment, the present invention can improve the work efficiency and construction safety of the power station construction, and effectively solve the contradiction between the construction and maintenance of electric facilities and the safety and reliable power supply of the system.

Description

technical field [0001] The invention relates to the technical field of substation lifting devices, in particular to a miniature crawler crane for substation maintenance. Background technique [0002] Cranes are often used for lifting equipment in power station expansion or renovation projects. Ordinary cranes are large in size. The swing and lifting of the lifting arm in the live equipment area is limited by the geographical location of the site and the surrounding live equipment. It is very inconvenient to use and has safety concerns. , Sometimes the power outage range has to be expanded to meet the conditions of use. For example, when replacing a 110KV outdoor current transformer, the current transformer is generally located behind the switch. The lifting height is affected by the passing line above, and the swing angle is limited by the switch; for another example, when replacing the 110KV bus PT, its installation position or the crane cannot reach it, or the lifting heig...

Problems solved by technology

[0006] However, although the above-mentioned small-sized lifting truck can directly reach the vicinity of the equipment, and adopts the lifting method of lifting, the lifting height is less affected by the live equipment above, and it is flexible, convenient and safe to use, but one is expensive, and the other is The hoisting method is also adopted, and the hoisting height is severely limited in the electrified area

Other products also use the lifting method, and their volume is too large to meet the on-site use of substations. So far, the small-scale crane trucks that can meet our requirements for substation projects are still blank in the domestic and foreign markets.
