Description

{Multipurpose Construction Vehicle for Inclined Shaft of Underground Tunnel}

The present invention relates to a multi-purpose construction equipment for underground tunnel inclined gauging, and more particularly, to a multi-purpose construction equipment for underground tunnel inclined gauging, more particularly, It is possible to prevent a safety accident in which the wire rope is cut off during the traction process and to provide a means for loading the burdens generated during the excavation work and a self traction function, To an underground tunnel inclined gangway multi-purpose construction equipment capable of improving the performance of the underground tunnel.

Generally, in the case of large cities, since the population of the city is several hundred thousand, it is the urban railway that allows citizens to use a large number of people at the same time.

These urban railways have evolved into several stages. The first urban railway began to run on the road surface, but as the city became more complicated, it served as a stumbling block to the operation of other means of transportation. As a result, traffic congestion, Due to problems such as vibrations, it turned into a subway that can solve problems such as noise, vibration, and urban congestion.

In the case of constructing underground structures such as underground parking lots, underground roads, underground communication areas, tunnels and underground waterways including the history of subways and subways, in order to access underground structures and grounds built in the ground, .

The access path may be a staircase, an escalator, an elevator, etc. In order to install a staircase or an escalator, the access passage must be inclined. Therefore, .

However, when the construction equipment according to the prior art works in a sloped gang, there is no separate fixing device or supporting device, so that the load can not be supported and a safety accident occurs.

In order to solve such a problem, an attempt has been made to attach an electric winch to a fixing device and to support it by connecting it with a construction equipment. However, since the electric winch is operated only by turning on and off the power, It is difficult to actively cope with the load or the traveling speed of the construction equipment, and there is a problem that the wire rope connecting the construction equipment is cut off or a safety accident occurs.

In addition, in the case of construction equipment according to the prior art, in addition to the construction equipment for underground tunnel construction, a load car such as a dump truck is additionally required to load the buoyancy generated in the slope gang during tunnel construction.

However, in the case of dump trucks, unlike the construction equipment in which most of the track-type tracks are composed of traveling wheels, a large-sized tire is constituted by a driving wheel, so that there is a high possibility that a safety accident In addition to the construction equipment for tunnel construction, additional equipment is installed, which lowers the overall efficiency of the slope mine work process and increases construction costs.

Therefore, it is possible to prevent safety accidents during construction of underground tunnels, to reduce the construction cost while improving the efficiency of the work process, and to be able to actively cope with the load and running speed of the construction equipment put into the sloped gang There is an urgent need for technology for such a construction equipment.
