Self-walking device of large transformer

Abstract

The invention discloses a self-walking device of a large transformer. The self-walking device comprises a walking wheel set, a hydraulic driving system, a control cabinet and a driven walking mechanism, wherein the walking wheel set comprises a plurality of walking wheel mechanisms, the walking wheel mechanisms are uniformly distributed and installed at the bottom of the transformer, the walking wheel mechanisms are power and carriers of the transformer, the hydraulic driving system and the control cabinet are integrated on the driven walking mechanism, the driven walking mechanism is hung onthe transformer through rigid connection, and one end of the hydraulic driving system is in transmission connection with the walking wheel mechanisms. The walking wheel set is provided with the corresponding hydraulic system, so that on-orbit self-walking displacement of the large transformer is realized, and many problems existing in a rope traction displacement mode are eliminated; a ground anchor does not need to be arranged on site, the conveying process is coherent and rapid, and the transfer time of more than ten days can be shortened to one day; and the self-walking device walks stably,safely and reliably, so that the operation efficiency is greatly improved, the engineering construction period or the shutdown maintenance period is shortened, and the economic benefit and the socialbenefit are extremely considerable.

Description

technical field

[0001] The invention relates to the field of operation transportation, in particular to a self-propelled device for on-rail transportation of a large transformer of a hydropower station. Background technique

[0002] With the rapid development of the hydropower industry, the scale of hydropower units is getting larger and larger, and the quality and volume of the main transformer of the power station are getting heavier and larger. Due to the lack of effective means of transfer, the installation and out-of-place maintenance of transformers have always been difficult. It's a very big problem. The conventional method of transportation is to pull through the noose system step by step, and many ground anchors need to be set in the middle. Due to the long transportation distance, the transportation operation has to be divided into many sections, which lacks continuity. At the same time, the traction force of the transformer is difficult Correct allocation and con...
