Abstract

A slagging-off machine for underground excavation subway rapid construction comprises a slagging-off device (1), a moving device (2), a driving control room (3), a driving device (4), a dust suppression water spraying device (5), a main machine frame (6), a control device (7) and a material slag conveying device (8). A driving device (4) and a driving control room (3) are connected above the mainframe (6), one side of the driving device (4) is connected with a transmission device (5), the bottom of the main frame (6) is connected with a moving device (2), and the main frame (6) is further connected with a control device (7) and a slag conveying device (8); and a slagging-off device (1) is connected to the main frame (6) at one end of the driving control room (3). The invention belongs tothe intelligent equipment industry, and the slagging-off machine can greatly increase the slagging-off width, greatly improve the working efficiency, improve the stability of the whole machine, achieve the purposes of dust removal, dust suppression and remote control, and has higher practicability and scientificity.

Description

technical field [0001] The invention belongs to the intelligent equipment industry, and relates to the technical field of rail transit and engineering machinery, in particular to a slag removal machine for rapid construction of underground excavation subways. Background technique [0002] In recent years, with the increasing number of subway tunnel projects in my country, the current subway construction generally adopts the construction technology of underground excavation method. Under certain conditions, the underground excavation construction method is to excavate and build linings underground without digging the ground. Structural tunnel construction methods. Although the construction technology of underground excavation method is relatively mature, the degree of mechanization is very low, and the main processes are all completed by manpower, resulting in low construction efficiency. In addition, the number of new generation workers born in the 80s and 90s is small and th...

AI Technical Summary

Problems solved by technology

Although the construction technology of underground excavation method is relatively mature, the degree of mechanization is very low, and the main processes are all completed by manpower, resulting in low construction efficiency. In addition, the number of new generation workers born in the 80s and 90s is small and they are unwilling to engage in heavy physical labor. Labor costs are getting higher and higher, so mechanization is an inevitable trend in the development of undercover methods

[0003] Existing conventional tunnel excavation equipment, the excavating arm only has the function of removing slag, and it needs a certain tunnel height to be used. In order to avoid landslides during the construction of underground tunnels for subway tunnels, the core soil must be preserved, so that the excavating arm of this type has the function of removing slag. The height and width of the slag cannot cover the entire tunnel, and the construction cannot be carried out across the obstacle of the core soil

In addition, currently all slag scrapers lack the device defect that can remove dust and suppress dust when slag is loaded. Because the slag scraper will generate a lot of dust when slag is loaded, the dust concentration is very high when the operator is operating, and the visibility of the working surface is relatively low. Low, directly affect the safety of production and work efficiency, at the same time, the dust may also cause adverse effects on the health of the operators, especially when working in the tunnel, the dust is more difficult to eliminate due to the influence of the environment

Dry materials will form an open dust source when loading slag, and it is difficult to disappear on the working surface. When working in a tunnel, due to the increasing dust concentration, and it is difficult for the light to penetrate the dust to see the working surface, it directly affects In order to improve work efficiency and safety in production, it is easy for workers to suffer from occupational diseases such as silicosis

Moreover, due to the harsh environment during underground excavation, sometimes loose earthwork falls, and accidents occur from time to time, it is difficult to ensure the safety of drivers during on-site operations.
