Telescopic-adjustable tunnel trolley and working method thereof

Abstract

The invention relates to a telescopic-adjustable tunnel trolley which comprises a rack. Crawler wheels are arranged below the rack, a workbench capable of ascending and descending relative to the rackis arranged above the rack, and a first sliding rail is arranged between the workbench and the rack; a first execution system capable of controlling the workbench to ascend and descend is arranged onthe rack. The invention further relates to a working method of the telescopic-adjustable tunnel trolley. The tunnel trolley is reasonable in structure and easy and convenient to operate; the height and width of a working platform can be adjusted according to the size and construction requirements of a construction site.

Description

technical field [0001] The invention relates to a telescopically adjustable tunnel trolley and a working method thereof. Background technique [0002] With the continuous development of technology and economy, in the field of highway and railway tunnel engineering, trolleys gradually replace the previous simple scaffolding and become an indispensable equipment in the construction process. The trolley has a wide range of uses and can meet a variety of construction needs, such as excavation, support, dangerous rock treatment, steel arch installation, steel mesh hanging, explosive loading, etc. [0003] Domestic ordinary tunnel operation trolleys are generally divided into three-layer operation trolleys and four-layer operation trolleys according to the size of excavated tunnels. Their operating platforms are fixed, which greatly restricts the operating area of ​​construction trolleys; and the tunnel The working environment is complex and needs to be processed at different loc...

AI Technical Summary

Problems solved by technology

[0003] Domestic ordinary tunnel operation trolleys are generally divided into three-layer operation trolleys and four-layer operation trolleys according to the size of excavated tunnels. Their operating platforms are fixed, which greatly restricts the operating area of ​​construction trolleys; and the tunnel The working environment is complex and needs to be processed at different locations at any time. Therefore, the fixed working platform needs to be rebuilt to meet the demand. However, this work is time-consuming and labor-intensive, which increases the operating cost and further affects the construction efficiency.

At present, ordinary rubber tires are mostly used for the movement of trolleys. In tunnel engineering construction with poor geological conditions and harsh environments, not only the safety of the tires cannot be guaranteed, but also the movement of the trolley requires more personnel and consumes a lot of energy. The time is longer, and the body is also easily damaged, so the safety factor is low and the reliability is not high
