Description

[Detailed description of the invention]

This issue 1 (well, related to the working equipment in the tunnel, details 1.
] Work (j゛)! There is an ISl b log on the work equipment. Conventionally, equipment for tunnel blowing (=JG) work is known, such as one mounted on a self-propelled work g7 vehicle.In other words, the above-mentioned The work is carried out while the work vehicle is gradually advanced in the direction of the axis of the tunnel. Rotation is used to carry in and out other work vehicles or to carry in and out equipment. In this case, it is impossible to speed up the tunnel 1'1t. Therefore, the present invention is designed to speed up the tunnel 1'1t. The purpose of the present invention is to make the loading and unloading of the tunnel in a suspended manner, and to increase the number of ffs in the tunnel. The present invention was constructed as follows.The present invention utilizes a 1'1 workbench of the 111 downtr type which has been previously developed and is publicly known. j；li

Alternatively, it is easy to carry in and out of the BS shrine. (2) Since it is possible to change the direction of the axis and the circumference of the tunnel by the suspension rail and the guide rail, a wide range of blowing (= J GJ
It can be performed. Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings. A certain device M by Haku Kinen can perform 11 jobs such as erection work of shoring (

A rail 11 is constructed, and the rail 11 is provided with bin racks arranged at equal pitches, to which the drive wheels 12 of the following four-wheel stand [1j 13] are sequentially engaged. The truck 1311 is shaped like a rectangular table, and on its side (the left side in Fig. 1) is equipped with an oil truck 14 that is driven by a driving device (not shown).
