Embodiments of the present invention will be described below with reference to the drawings.

<A> Outline of drilling machine attitude control device The drilling machine 1 is usually used when constructing a tunnel 4 as shown in FIG.
As shown in the figure, it is arranged in the tunnel 4 together with the tunnel machine 2 and the rod bogie 3, and is used for boring for drainage of a face and boring for geological investigation.

The drilling machine attitude control device 10 freely controls the attitude of the drilling machine 1, and as shown in FIGS. 2 to 6, a rotating unit 30 rotatable on a bogie 20, a boom 32, The attitude of the drilling machine 1 is controlled by controlling the drilling machine support 40 and the like.

The truck 20 is provided with running wheels 22 on a frame 21 of the truck.
Is installed, and a hydraulic hoist 23 for wire lines is
Is provided.

[0010] The boom 32 is attached to the rotating part 30 on the trolley 20, and can be turned with respect to the trolley 20, and the elevation angle is variably controlled.

The drilling machine 1 is mounted on a boom 32 via a drilling support 40, and is capable of turning and variably controlling the undulation angle. In addition, a well-known thing can be used for the drilling machine 1, For example, Adorokyl RPD-100 (made by Minken Mining Co., Ltd.) can be used.

<B> The boom rotating unit 30 is rotatably arranged on the carriage 20, and is controlled by a turning motor 31. The boom 32 is attached to the rotating part so that the elevation angle can be variably controlled.

In a method of variably controlling the elevation angle, for example, the boom 32 is divided into two forks and attached to the rotating unit 30 so as to be able to undulate, and a boom elevation angle jack 41 is disposed on the boom 32 and the rotating unit 30 between the forks. By expanding and contracting the boom elevation angle jack 41, the elevation angle of the boom 32 can be freely controlled. In addition, the rotating unit 30 is also provided with a valve unit 11 and a counterweight 12.

The valve unit 11 uses an electromagnetic valve instead of the lever type hydraulic switching valve, and is of a remote control type.

<C> Drilling Machine Support The drilling machine support 40 supports the drilling machine 1 so that the drilling direction of the drilling machine 1 can be freely controlled.
2 can be pivotally attached to the tip.

There are various methods for controlling the turning angle of the drilling tool support 40. For example, a turning jack 41 is rotatably mounted between the side of the support 40 and the boom 32. By extending and retracting the turning jack 41, the support 40 can be turned with respect to the boom 32.

The drilling machine 1 is mounted on the head of the drilling machine support 40 so that the undulating angle can be freely adjusted. The mounting location of the drilling machine 1 is, for example, undulatingly mounted on a guide shell 50 as a base. In order to control the undulation angle of the drilling machine 1, for example, an undulating jack 42 is arranged between the drilling machine support 40 and the guide shell 50. The undulating angle of the drilling machine 1 can be controlled by expanding and contracting the undulating jack 42.

By attaching the drilling machine 1 to the support 40 in this manner, the drilling machine 1 having a large load can be controlled quickly, easily and safely by controlling the turning jack 41 and the undulating jack 42. can do.

Hereinafter, the operation of the drilling machine attitude control device will be described.

<A> Installation of the drilling machine attitude control device The drilling machine attitude control device 10 and the drilling machine 1 are mounted on the bogie 20 and carried into the rear of the tunnel excavator 2. A hydraulic hose (not shown) is connected to the drilling machine attitude control device 10 and the drilling machine 1.

<B> Operation of the drilling machine attitude control device By operating a remote control panel (not shown), the turning motor 31 is driven to turn the attitude control device 10 and the drilling machine 1 is drilled. Move to near the scheduled line. Next, the remote control panel is operated, and the jack 33 for the boom elevation angle and the jack 4 for the turning are operated.
1. The jack 42 for undulation is expanded and contracted to match the designated hole.

<C> Start of drilling The drilling machine 1 receives the reaction force of the drilling machine 1 from the nearby anchor and starts drilling.

[0023]

According to the present invention, the following effects can be obtained. <A> By mounting the drilling machine on the trolley and controlling it with the attitude control device, the drilling machine can be easily and safely set to a predetermined drilling position in a short time. <B> Since the drilling machine can be set in a wide range of positions, the incidence angle of the drilling can be reduced, and therefore, the accuracy of soil survey can be improved. <C> Since the valve unit for controlling the attitude can be of a remote control type, it can be prevented from being caught or pinched during operation.
